    To evaluate and compare the efficacy of the combination of midazolam and dexamethasone, with midazolam and dexamethasone alone, for the prevention of postoperative nausea and vomiting (PONV) in female patients undergoing middle ear surgery. A prospective, randomized, double-blind, placebo-controlled study in 80 female patients (mean age 32.6 years), undergoing middle ear surgery with general anesthesia at Ohud Hospital, Madina, Kingdom of Saudi Arabia from May 2007 to May 2008. Patients were classified into 4 groups. They received intravenous normal saline (S group), midazolam 0.075 mg/kg (M group), or dexamethasone 10 mg (D group), or a combination of midazolam and dexamethasone (MD group), before the induction of anesthesia. Postoperatively for 24 hours observation and assessment of nausea, vomiting, rescue anti-emetics, and side effects of the study drugs such as headache and drowsiness were carried out. There was a significant difference between the 4 groups. The MD group was the least to develop PONV compared to other groups (p<0.01). Regarding nausea, there was a non-significant difference between the 4 groups, although the MD group developed the least symptoms among the 4 groups, there were no significant differences in pain intensity and side effects such as, headache, dizziness, and drowsiness between the 4 groups. The combination of midazolam 0.075 mg/kg and dexamethasone 10 mg intravenously is better than either drug alone in reducing the incidence of PONV in female patients after middle ear surgery.

    To find out the occurrence of postoperative nausea and vomiting (PONY) in oral and maxillofacial surgery done under general anaesthesia and to evaluate the purpose of using prophylactic antiemetic drugs. Design: Observational study. Place and Duration of the Study: Oral and Maxillofacial Department, KEMU / Mayo Hospital Lahore, from September 20 II to June 2012. Method: The number of patients who were operated in oral and maxillofacial surgery ward irrespective of age and gender for this study were 240. Risk factors related with PONY including gender, anesthetic drug used, surgical procedure, approach' used, total time of surgery and postoperative use of opioids were investigated. A wait and watch scheme was followed in patients with complaint of PONY. Antiemetics to be given in those cases where more than 2 episodes of vomiting took place. Results: It was found out that only II patients experienced from nausea and vomiting in post operative period. A notable relation was seen between PONY and female population, total time of surgery, anesthetic drug, surgery of tumor and temporomandibular joint. The surgical approach and opioids in postoperative period for PONY were found to be insignificant. Conclusion: PONY is not a significant finding in oral and maxillofacial surgery. We find out that there is no logic for the use of prophylactic antiemetic drugs in maxillofacial surgery. (author)

    Approximately 30-59% of patients undergoing cranial or craniospinal radiotherapy experience nausea and/or vomiting. Here, we evaluated the effectiveness of granisetron for controlling emesis in patients treated with cranial or craniospinal radiotherapy. Between December 2011 and January 2013, 34 patients (19 males, 15 females; age range, 3-80 years) received cranial or craniospinal radiotherapy at our department. All but one male patient, who developed meningitis during the irradiation period were enrolled in this retrospective study. Patients who experienced irradiation-induced vomiting (grade 1) or nausea (grade 2) were treated with granisetron as a rescue anti-emetic. Episodes were graded as no vomiting, no nausea, no anti-emetic; no vomiting, nausea, no anti-emetic; no vomiting, nausea with anti-emetic; and vomiting. Of the 9 patients who underwent whole-brain or whole neural-axis irradiation, 5 (55.6%) experienced grade 2 nausea or vomiting. Two of 6 patients (33.3%) treated with whole ventricle irradiation experienced grade 2 nausea or vomiting. Three of 18 patients (16.7%) who underwent local-field irradiation experienced grade 2 nausea or vomiting. Patients who underwent wide-field irradiation experienced nausea, vomiting, and anorexia (p<0.05). Complete response (no vomiting, no additional rescue anti-emetic, and no nausea) was observed in 5 of 9 patients treated with granisetron. Four of 9 patients (44.4%) treated with granisetron experienced constipation (grade 1 or 2); its administration had no major adverse effects in our study population. Rescue therapy with granisetron is safe and effective to treat nausea and vomiting in patients subjected to cranial or craniospinal irradiation. (author)

    A series of experiments were run to evaluate the effect of antiemetics on the acquisition and recall of a conditioned taste aversion induced by exposure to ionizing radiation or by injection of lithium chloride. Groups of male rats were exposed to 100 rad gamma radiation or 3 mEq/kg lithium chloride following consumption of a 10% sucrose solution. They were then injected with saline or with one of three antiemetics (prochlorperazine, trimethobenzamide, or cyclizine) at dose levels that have been reported to be effective in attenuating a previously acquired lithium chloride-induced taste aversion. The pretreatments with antiemetics had no effect on the acquisition or recall of either the lithium chloride- or radiation-induced taste aversion. The data suggest that antiemetics do not disrupt lithium chloride-induced taste aversions as previously reported, nor do they effect radiation-induced taste aversion learning

    The antiemetic effects and safety of granisetron and palonosetron against chemotherapy-induced nausea and vomiting (CINV) were retrospectively evaluated in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy. A total of 61 patients were eligible for this study. Before starting the bendamustine-based chemotherapy, granisetron or palonosetron were intravenously administered with or without aprepitant and/or dexamethasone. The proportions of patients with complete control (CC) during the overall (during the 6 days after the start of the chemotherapy), acute (up to 2 days), and delayed (3 to 6 days) phases were assessed. CC was defined as complete response with only grade 0-1 nausea, no vomiting, and no use of antiemetic rescue medication. Granisetron or palonosetron alone were administered to 9 and 19 patients, respectively. Aprepitant and/or dexamethasone were combined with granisetron and palonosetron in 28 and 5 patients, respectively. Acute CINV was completely controlled in all patients. Both granisetron monotherapy and palonosetron combination therapy could provide good control of delayed CINV, although the CC rates during the delayed and overall phases were not significantly different among mono- and combination therapy of the antiemetics. There was no significant difference in the frequencies of adverse drug events between the granisetron and palonosetron treatment groups. The present study showed that the antiemetic efficacy and safety of granisetron-based therapy were non-inferior to those of palonosetron-based therapy. Taken together with treatment costs, granisetron monotherapy would be adequate to prevent CINV in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy.

    The 5-HT 3 receptor antagonists are the most potent antiemetics known at present. Lerisetron is a new 5-HT 3 receptor antagonist chemically unrelated to other antagonists like Ondansetron. An emesis model in the dog induced by irradiation with 60 Co was used, and 8 Gy were administered over the total body surface. An irradiated control group was established and received no medication, and two irradiated groups received treatment with either Ondansetron or Lerisetron. The 'up-down' technique was employed to determine the effective dose (ED 50 ). A logarithmic scale was used to increase or decrease the doses in each case. The initial doses were 300 μg/kg for Ondansetron and 100 μg/kg for Lerisetron. All animals in the control group vomited. The ED 50 of Ondansetron was 178 ± 151 μg/kg body wt and that of Lerisetron was 63 ± 18 μg/kg. Lerisetron is more potent and presented less individual variability than Ondansetron, but its antiemetic effects were equally effective. (orig.)

    Triplet antiemetic therapy with neurokinin 1 receptor blocker, 5-hydroxytryptamine receptor blocker and steroids is commonly used in patients who are highly emetic after chemotherapy. However, an alternative antiemetic therapy for patients who are resistant to triplet antiemetic therapy is not established. Olanzapine is recommended in the guidelines as an optional antiemetic drug. However, the effectiveness of adding olanzapine to triplet antiemetic therapy is unknown. In this study, the effectiveness and safety of adding olanzapine to triplet antiemetic therapy with aprepitant, palonosetron and dexamethasone as highly emetic anthracycline-containing adjuvant chemotherapy for primary breast cancer patients were prospectively investigated. Forty-five patients with breast cancer who experienced >Grade 1 nausea or any vomiting after the first cycle of chemotherapy using both epirubicin and cyclophosphamide were included. Low-dose olanzapine (2.5 mg/day) was administered orally from the first day of chemotherapy for 4 days, and the number of episodes of vomiting, scale of nausea, dietary intake and somnolence were compared with the symptoms after the first cycle. As the primary endpoint, the nausea grade was significantly improved by adding olanzapine (P effectiveness and tolerability of adding low-dose olanzapine for patients with insufficient nausea relief with triplet antiemetic therapy consisting of palonosetron, steroid and aprepitant.

    Szarvas, Szilvia

    2012-02-03

    In a prospective, double-blinded, randomized trial, we evaluated the efficacy of IV (a) dexamethasone 8 mg, (b) ondansetron 8 mg, and (c) dexamethasone 8 mg plus ondansetron 4 mg for the prevention of postoperative nausea, vomiting (PONV), and pruritus in 130 (ASA physical status I to III) patients undergoing elective major orthopedic surgery after spinal anesthesia with hyperbaric 0.5% bupivacaine and intrathecal morphine. After spinal anesthesia, patients were randomized to one of three groups. Failure of PONV prophylaxis in the 24-h postoperative period occurred more frequently in patients who received dexamethasone alone (29 of 40; 73%) compared with those who received either ondansetron alone (23 of 47; 49%) (P = 0.02) or dexamethasone plus ondansetron together (19 of 43; 44%)(P = 0.01). There was no difference in the incidence of failure of prophylaxis of pruritus (70%, 72%, and 70% in dexamethasone 8 mg, ondansetron 8 mg, and dexamethasone 8 mg plus ondansetron 4 mg, respectively) (P > 0.1) in the 24-h postoperative period. We conclude that the administration of dexamethasone 8 mg with ondansetron 4 mg has no added benefit compared with ondansetron 8 mg alone in the prophylaxis of PONV and pruritus. IMPLICATIONS: Postoperative nausea and vomiting (PONV) and pruritus are common side effects after spinal opioid administration. In this study, dexamethasone 8 mg plus ondansetron 4 mg was as effective as ondansetron 8 mg. The administration of dexamethasone alone was associated with a frequent incidence of PONV, demonstrating a lack of efficacy. This has important cost implications.

    CONCLUSION: Although this study is not prospective, it is homogenous for treatment modalities and patient selection. Complete response was observed in 63% of courses; however this antiemetic affect is not found to be satisfactory. In order to develope better protocols there is need for prospective studies on homogenous group. Antiemetic efficiency has to associate for chemotherapy protocols.

    2013-01-01

    In a prospective cohort study of antiemetic therapy conducted in Malaysia, a total of 94 patients received low emetogenic chemotherapy (LEC) with or without granisetron injections as the primary prophylaxis for chemotherapy-induced nausea and vomiting (CINV). This study is a retrospective cost analysis of two antiemetic regimens from the payer perspective. This cost evaluation refers to 2011, the year in which the observation was conducted. Direct costs incurred by hospitals including the drug acquisition, materials and time spent for clinical activities from prescribing to dispensing of home medications were evaluated (MYR 1=$0.32 USD). As reported to be significantly different between two regimens (96.1% vs 81.0%; p=0.017), the complete response rate of acute emesis which was defined as a patient successfully treated without any emesis episode within 24 hours after LEC was used as the main indicator for effectiveness. Antiemetic drug acquisition cost per patient was 40.7 times higher for the granisetron-based regimen than for the standard regimen (MYR 64.3 vs 1.58). When both the costs for materials and clinical activities were included, the total cost per patient was 8.68 times higher for the granisetron-based regimen (MYR 73.5 vs 8.47). Considering the complete response rates, the mean cost per successfully treated patient in granisetron group was 7.31 times higher (MYR 76.5 vs 10.5). The incremental cost-effectiveness ratio (ICER) with granisetron-based regimen, relative to the standard regimen, was MYR 430.7. It was found to be most sensitive to the change of antiemetic effects of granisetron-based regimen. While providing a better efficacy in acute emesis control, the low incidence of acute emesis and high ICER makes use of granisetron as primary prophylaxis in LEC controversial.

    The acute antiemetic effect was compared between oral azasetron and intravenous granisetron based on the 5-hydroxytryptamine(3) (5-HT(3)) receptor occupancy theory. Receptor occupancy was estimated from reported data on plasma concentrations and affinity constants to 5-HT(3) receptor. A randomized non-inferiority study comparing acute antiemetic effects between oral azasetron and intravenous granisetron was performed in 105 patients receiving the first course of carboplatin-based chemotherapy for lung cancer. Azasetron exhibited the highest 5-HT(3) receptor occupancy among various first-generation 5-HT(3) antagonists. The complete response to oral azasetron was shown to be non-inferior to that of intravenous granisetron, in which the risk difference was 0.0004 (95% confidence interval: -0.0519-0.0527). The lower limit of the confidence intervals did not exceed the negative non-inferiority margin (-0.1). The complete response during the overall period was not different (68% versus 67%). Oral azasetron was found to be non-inferior to intravenous granisetron in the acute antiemetic effect against moderately emetogenic chemotherapy.

    The authors tested the effectiveness of orally administred delta-9-tetrahydrocannabinol (THC) as compared to prochlorperazine for the alleviation of symptoms, such as vomiting and nausea, experienced by patients receiving radiotherapy. The test subjects rated the severity of their illness, as well as the extent of their subsequent moods, their level of concentration, their amount of physical activity, and their desire for social interaction. They chose the drug they preferred and recorded its side effects. The use of THC was slightly more beneficial than the use of prochlorperazine

    Full Text Available Rhus verniciflua Stoke has been commonly used in traditional medicine to treat gastrointestinal (GI dysfunction diseases. In order to investigate pharmacological properties of Rhus verniciflua Stoke water extract (RVX on cisplatin-induced amnesia, RVX (0, 25, 50, or 100 mg/kg was orally administrated for five consecutive days after a single intraperitoneal injection of cisplatin (6 mg/kg to SD rat. Cisplatin injection significantly increased the kaolin intake (emesis but reduced the normal diet intake (anorexia whereas the RVX treatment significantly improved these abnormal diet behaviors at both the acute and delayed phase. The serotonin concentration and the related gene expressions (5-HT3 receptors and SERT in small intestine tissue were abnormally altered by cisplatin injection, which were significantly attenuated by the RVX treatment. Histological findings of gastrointestinal tracts, as well as the proteins level of proinflammatory cytokines (TNF-α, IL-6, and IL-1β, revealed the beneficial effect of RVX on cisplatin-induced gastrointestinal inflammation. In addition, RVX significantly improved cisplatin-induced myelosuppression, as evidenced by the observation of leukopenia and by histological examinations in bone marrow. Our findings collectively indicated Rhus verniciflua Stoke improved the resistance of rats to chemotherapy-related adverse effects in the gastrointestinal track and bone marrow.

    1977-11-01

    The effect of prophylactic digitalization on the development of left ventricular hypertrophy was studied in adult rats. Digitoxin, 0.1 mg/100 g body wt or solvent was given daily for 1 wk prior to either aortic constriction or sham operation and was continued until the animals were killed, either 1 or 4 wk after surgery. A hemodynamic study was done in those animals killed 1 wk after surgery; hearts of all animals were examined for evidence of myocardial hypertrophy. Constriction of the ascending aorta had no significant effect on cardiac output but did reduce peak flow velocity and flow acceleration. An increase in left ventricular mass, RNA, and hydroxyproline was found in the animals with aortic constriction. Digitoxin treatment did not alter peak flow velocity or flow acceleration, but did significantly increase isovolumic (dP/dt)P-1. Digitoxin had no effect on body weight, heart weight, RNA, or hydroxyproline in either the sham-operated animals or in the animals with aortic constriction. Therefore, despite plasma digitoxin levels sufficient to affect myocardial contractility, left ventricular hypertrophy still developed after aortic constriction.

    Research on patient-reported outcomes indicates that constipation is a common adverse effect of chemotherapy, and the use of 5-hydroxytryptamine (serotonin; 5HT3) receptor antagonists aggravates this condition. As cancer patients take multiple drugs as a part of their clinical management, a non-pharmacological self-management (SM) of constipation would be recommended. We aimed to evaluate the effectiveness of a SM program on antiemetic-induced constipation in cancer patients. Thirty patients with breast cancer, receiving 5HT3 receptor antagonists to prevent emesis during chemotherapy were randomly assigned to the intervention or control group. The SM program consisted of abdominal massage, abdominal muscle stretching, and education on proper defecation position. The intervention group started the program before the first chemotherapy cycle, whereas patients in the wait-list control group received the program on the day before their second chemotherapy cycle. The primary outcome was constipation severity, assessed by the constipation assessment scale (CAS, sum of eight components). The secondary outcome included each CAS component (0-2 points) and mood states. A self-reported assessment of satisfaction with the program was performed. The program produced a statistically and clinically significant alleviation of constipation severity (mean difference in CAS, -3.00; P = 0.02), decrease in the likelihood of a small volume of stool (P = 0.03), and decrease in depression and dejection (P = 0.02). With regards to program satisfaction, 43.6 and 26.4 % patients rated the program as excellent and good, respectively. Our SM program is effective for mitigating the symptoms of antiemetic-induced constipation during chemotherapy.

    2017-01-01

    In the present study, the antiemetic effect of palonosetron, not combined with dexamethasone and aprepitant, on chemotherapy-induced nausea and vomiting was evaluated in patients with malignant lymphoma receiving first-line rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy, and was compared to that of granisetron. A total of 74 patients with non-Hodgkin lymphoma were included in this study (April 2007 to December 2015). Palonosetron (0.75 mg) or granisetron (3 mg) was intravenously administered before R-CHOP therapy. The proportions of patients with complete response (CR) during the overall (0-120 h after the start of R-CHOP therapy), acute (0-24 h) and delayed (24-120 h) phases were evaluated. CR was defined as no vomiting and no use of antiemetic rescue medication. A total of 32 and 42 patients were treated with palonosetron and granisetron, respectively. The CR rate in the palonosetron group was significantly higher than that in the granisetron group during the delayed phase (90.6 and 61.9%, respectively; p=0.007). Logistic regression analysis showed that use of palonosetron improved the CR rate during the delayed phase, compared to use of granisetron. Female sex, age less than 60 years, no habitual alcohol intake, and Eastern Cooperative Oncology Group performance status (ECOG-PS) score of 1 were significant risk factors associated with non-CR. The findings of this study suggested the superiority of palonosetron to granisetron, without accompanying dexamethasone and aprepitant, for chemotherapy-induced nausea and vomiting in patients with malignant lymphoma.

    : A previous hip fracture more than doubles the risk of a contralateral hip fracture. Pharmacologic and environmental interventions to prevent hip fracture have documented poor compliance. The purpose of this study was to examine the cost-effectiveness of prophylactic fixation of the uninjured hip to prevent contralateral hip fracture. : A Markov state-transition model was used to evaluate the cost and quality-adjusted life-years (QALYs) for unilateral fixation of hip fracture alone (including internal fixation or arthroplasty) compared with unilateral fixation and contralateral prophylactic hip fixation performed at the time of hip fracture or unilateral fixation and bilateral hip pad protection. Prophylactic fixation involved placement of a cephalomedullary nail in the uninjured hip and was initially assumed to have a relative risk of a contralateral fracture of 1%. Health states included good health, surgery-related complications requiring a second operation (infection, osteonecrosis, nonunion, and malunion), fracture of the uninjured hip, and death. The primary outcome measure was the incremental cost-effectiveness ratio estimated as cost per QALY gained in 2006 US dollars with incremental cost-effectiveness ratios below $50,000 per QALY gained considered cost-effective. Sensitivity analyses evaluated the impact of patient age, annual mortality and complication rates, intervention effectiveness, utilities, and costs on the value of prophylactic fixation. : In the baseline analysis, in a 79-year-old woman, prophylactic fixation was not found to be cost-effective (incremental cost-effectiveness ratio = $142,795/QALY). However, prophylactic fixation was found to be a cost-effective method to prevent contralateral hip fracture in: 1) women 71 to 75 years old who had 30% greater relative risk for a contralateral fracture; and 2) women younger than age 70 years. Cost-effectiveness was greater when the additional costs of prophylaxis were less than $6000. However, for

    Ondansetron (GR 38032F) is a highly selective 5-HT3 receptor antagonist, one of a new class of compounds which may have several therapeutic applications. Animal and clinical studies show that ondansetron reduces the 24-hour incidence and severity of nausea and vomiting induced by cytotoxic drugs, including cisplatin, and by single exposure, high dose radiation. Ondansetron is more effective than high dose metoclopramide in the 24 hours following chemotherapy, and preliminary clinical evidence suggests that it is equally effective in the following 4 days. It is also more effective than the moderate doses of metoclopramide used to suppress emesis following radiotherapy. The antiemetic efficacy of ondansetron is enhanced by dexamethasone in cisplatin-treated patients. Importantly, extrapyramidal effects have not been reported with ondansetron. Further comparisons are required with standard combination antiemetic therapy to complement the data presently available. Thus, ondansetron is a promising new agent for prophylaxis against nausea and vomiting in chemotherapy and radiotherapy. It may be particularly useful in young and elderly patients who are more susceptible to extrapyramidal symptoms induced by high dose metoclopramide. With its improved tolerability and clinical response profiles, ondansetron represents an important advance in a difficult area of therapeutics. 101 refs.

    The objective of this study was to examine the effect of prophylactic continuous positive airway pressure (CPAP) on infants born in 25 South American neonatal intensive care units affiliated with the Neocosur Neonatal Network using novel multivariate matching methods. A prospective cohort was constructed of infants with a birth weight 500 to 1500 g born between 2005 and 2011 who clinically were eligible for prophylactic CPAP. Patients who received prophylactic CPAP were matched to those who did not on 23 clinical and sociodemographic variables (N=1268). Outcomes were analyzed using the McNemar's test. Infants not receiving prophylactic CPAP had higher mortality rates (odds ratio (OR)=1.69, 95% confidence interval (CI) 1.17, 2.46), need for any mechanical ventilation (OR=1.68, 95% CI 1.33, 2.14) and death or bronchopulmonary dysplasia (BPD) (OR=1.47, 95% CI 1.09, 1.98). The benefit of prophylactic CPAP varied by birth weight and gender. The implementation of this process was associated with a significant improvement in survival and survival free of BPD.

    Resistance to antiemetic treatment with 5-hydroxytryptamine 3 receptor antagonists is a problem, with 20-30% of patients showing unsatisfactory responses. Efflux transport by P-glycoprotein, encoded by the ATP-binding cassette ABCB1 gene in the blood-brain barrier, has been the suggested resistance mechanism. We evaluated the association between the antiemetic efficacy of granisetron plus dexamethasone and ABCB1 polymorphisms 3435C>T and 2677G>T/A. Sixty-four breast cancer patients treated with doxorubicin plus cyclophosphamide were evaluated for their responses to antiemetic therapy. Genotyping of patient DNA samples for ABCB1 single nucleotide polymorphisms was performed; the genotypes were then investigated for their association with the efficacy of prophylactic antiemetics. The acute phase complete response rate was 83% in GG subjects (n = 12), and 69% (n = 35) and 41% (n = 17) in heterozygous and homozygous carriers of the 2677T/A allele, respectively (p = 0.047). The ABCB1 2677 TT genotype group showed significantly lower rates of complete control of acute emesis than the group with GG genotypes (p = 0.045). No significant association with complete response was found for 3435C>T (p = 0.190). ABCB1 polymorphisms may influence the extent of acute emesis control in granisetron-treated patients, making the ABCB1 genotype a predictor of prophylactic antiemetic response.

  18. A review of granisetron, 5-hydroxytryptamine3 receptor antagonists, and other antiemetics.

    Nausea and vomiting are 2 of the most upsetting adverse reactions of chemotherapy. Current guidelines propose 5-hydroxytryptamine3 (5-HT3) receptor antagonists as a pharmacologic intervention for acute and delayed nausea and vomiting [chemotherapy-induced nausea and vomiting (CINV)] associated with moderately and highly emetogenic chemotherapy. Meanwhile, both postoperative nausea and vomiting (PONV) and postdischarge nausea and vomiting are challenging situations after surgeries and procedures. Prophylactic and therapeutic combinations of antiemetics are recommended in patients at high risk of suffering from PONV and postdischarge nausea and vomiting. Granisetron (Kytril) is a selective 5-HT3 receptor antagonist that does not induce or inhibit the hepatic cytochrome P-450 system in vitro. There are also 4 other antagonists of 5-HT3 receptor (dolasetron, ondansetron, palonosetron, and tropisetron) being metabolized via the CYP2D6 and are subject to potential genetic polymorphism. The launch of a new class of antiemetics, the substance P/neurokinin1 receptor antagonists, was attributed to the scientific update on the central generator responsible for emesis and role of substance P. There has been mounting interest in exploring integrative medicine, either acupuncture or acustimulation of P6 (Nei-Kuwan), to complement the western medicine for prevention and management of nausea and vomiting. The potential application of cannabinoids, either alone or in combination with other agents of different mechanism, could contribute further to improve outcome in CINV. Implementation of future treatment guidelines for more effective management of CINV and PONV could certainly improve the efficacy and outcome of cancer and postoperative care.

    Patients with head and neck carcinoma are often provided concurrent chemoradiotherapy (CCRT), but they experience severe mucositis and dysphagia. These side effects can lead to decreased oral intake, resulting in interruption of treatment. In our hospital, from September 2007, all patients with oropharyngeal cancer who were to receive CCRT, were principally offered percutaneous endoscopic gastrostomy (PEG) before the start of treatment, and tube feeding was started when swallowing became impaired, to accomplish the treatment as planned. To evaluate the effect of prophylactic PEG, outcome measures in this study included the frequency of unplanned break from CCRT, nutritional deterioration and required analgesic during CCRT, complication of PEG, and patient satisfaction between 15 patients with PEG and 11 patients without PEG as a control group. Although no significant weight loss occurred in either group, there were fewer patients with a Body Mass Index <18.5 in the PEG group after CCRT than in the control group. Regarding the treatment, most patients were satisfied with their PEG and considered that prophylactic PEG was necessary and helpful in completing the CCRT. This study suggests that prophylactic PEG helps patients to complete CCRT both mentally and nutritionally. (author)

    The purpose of this prospective, randomized, double-blind, placebo-controlled study was to determine the effect of prophylactic amoxicillin on the occurrence of endodontic flare-up in asymptomatic, necrotic teeth. Seventy patients participated and had a clinical diagnosis of an asymptomatic, necrotic tooth with associated periapical radiolucency. One hour before endodontic treatment, patients randomly received either 3 g of amoxicillin or 3 g of a placebo control in a double-blind manner. After endodontic treatment, each patient received: ibuprofen; acetaminophen with codeine (30 mg); and a 5 1/2-day diary to record pain, swelling, percussion pain, and number and type of pain medication taken. The results demonstrated 10% of the 70 patients had a flare-up characterized by moderate-to-severe postoperative pain or swelling that began approximately 30 h after endodontic treatment and persisted for an average of 74 h. Of the seven patients who had flare-ups, 4 were in the amoxicillin group and 3 were not. Prophylactic amoxicillin did not significantly (p = 0.80) influence the endodontic flare-up. We concluded that a prophylactic dose of amoxicillin before endodontic treatment of asymptomatic, necrotic teeth had no effect on the endodontic flare-up.

    Full Text Available Prophylactic antipyretic administration decreases the post-vaccination adverse reactions. Recent study finds that they may also decrease the antibody responses to several vaccine antigens. This systematic review aimed to assess the evidence for a relationship between prophylactic antipyretic administration, post-vaccination adverse events, and antibody response in children.A systematic search of major databases including MEDLINE and EMBASE was carried out till March 2014. Randomized controlled trials (RCTs comparing prophylactic antipyretic treatment versus placebo post-vaccination in children ≤ 6 years of age were included. Two reviewers independently applied eligibility criteria, assessed the studies for methodological quality, and extracted data [PROSPERO registration: CRD42014009717].Of 2579 citations retrieved, a total of 13 RCTs including 5077 children were included in the review. Prophylactic antipyretic administration significantly reduced the febrile reactions (≥ 38.0 °C after primary and booster vaccinations. Though there were statistically significant differences in the antibody responses between the two groups, the prophylactic PCM group had what would be considered protective levels of antibodies to all of the antigens given after the primary and booster vaccinations. No significant difference in the nasopharyngeal carriage rates (short-term and long-term of H. influenzae or S. pneumoniae serotypes was found between the prophylactic and no prophylactic PCM group. There was a significant reduction in the local and systemic symptoms after primary, but not booster vaccinations.Though prophylactic antipyretic administration leads to relief of the local and systemic symptoms after primary vaccinations, there is a reduction in antibody responses to some vaccine antigens without any effect on the nasopharyngeal carriage rates of S. pneumoniae & H. influenza serotypes. Future trials and surveillance programs should also aim at

    The use of radiation has become an integral part of modern life. Interest has been generated to develop potential drug of plant origin for the modification of radiation toxicity. Common nutritional plants such as flaxseed and sesame are rich of lignan and may prove efficient antioxidants. The lignan like secoisolericiresinol and pinoresinol found in flaxseed and sesame are reported to have strong antioxidant nature. Cyclophosphamide induced decline in the level of GSH, GSH-Px and alkaline phosphatase was also significantly averted by flaxseed oil in mice blood. The high antioxidative properties of sesame appear to be related to lignans, such as sesamol, sesamolinol, pinoresinol, p1 and sesaminol. The mice have been administered with flaxseed oil and sesame oil for fifteen days, before an acute dose of radiation (5 Gy at a dose rate of 1.07 Gy/min). Both the herbs have been found to check the level of lipid peroxidation and protein degradation induced by radiation in mice brain. The survivability in terms of life span showed much better picture in sesame oil pretreated irradiated mice in comparison to linseed oil pretreated irradiated mice. Statistically analyzed survival data produced a dose reduction factor (DRF) = 1.41 for flaxseed oil and 1.45 for sesame oil. The results indicate that sesame oil provide a better protection in comparison to linseed oil. Since flaxseed and sesame oil have demonstrated excellent antioxidative effect against radiation, it would further pave way to the formulation of medicine against radiation and several radiomimetic drug induced toxicity

    Objective: To discuss the effects of prophylactic chemotherapy on the outcomes and prognosis of invasive mole patients. Methods: One hundred and fifteen invasive mole (IM) patients older than 40 years were registered in Peking Union Medical Collage Hospital.Eleven of them were treated with prophylactic chemotherapy before diagnosed as IM prophylactic chemotherapy group, while the other 104 cases received therapeutic chemotherapy after diagnosed as IM (non-prophylactic chemotherapy group). The general clinical data (including age, clinical stage, risk factor score), treatment, outcomes and relapse of patients were retrospectively compared between two groups. Results: (1) The age of prophylactic chemotherapy group and non-prophylactic chemotherapy group were (47±5) versus (46±4) years old. Ratio of clinical stageⅠ-Ⅱ were 3/11 versus 29.8% (31/104), clinical stage Ⅲ-Ⅳ were 8/11 versus 70.2% (73/104). Ratio of risk factor score 0-6 were 11/11 versus 84.6% (88/104), risk factor score >6 were 0 versus 15.4% (16/104). There were no significant statistical differences between two groups in age, clinical stage or risk factor score (all P> 0.05). (2) Treatment: the total chemotherapy courses between prophylactic chemotherapy group and non-prophylactic chemotherapy group (median 7 versus 5) were significantly different ( Z= 3.071, P= 0.002). There were no significant statistical differences between two groups in the chemotherapy courses until negative conversion of β-hCG, consolidation chemotherapy courses, total therapeutic chemotherapy courses or ratio of hysterectomy (all P> 0.05). (3) Outcomes and relapse: between the prophylactic chemotherapy group and the non-prophylactic chemotherapy group, the complete remission rate were 11/11 versus 98.1%(102/104), the relapse rate were 0 versus 1.0%(1/102). There were no significant difference between the two groups in outcomes or relapse rate ( P> 0.05). Conclusions: Prophylactic chemotherapy does not substantially

    Negative pressure wound therapy (NPWT) is increasingly used prophylactically following surgery despite limited evidence of clinical or cost-effectiveness. To evaluate whether NPWT is cost-effective compared to standard care, for the prevention of surgical site infection (SSI) in obese women undergoing elective caesarean section, and inform development of a larger trial. An economic evaluation was conducted alongside a pilot randomised controlled trial at one Australian hospital, in which women were randomised to NPWT (n = 44) or standard care (n = 43). A public health care provider perspective and time horizon to four weeks post-discharge was adopted. Cost-effectiveness assessment was based on incremental cost per SSI prevented and per quality-adjusted life year (QALY) gained. Patients receiving NPWT each received health care costing AU$5887 (±1038) and reported 0.069 (±0.010) QALYs compared to AU$5754 (±1484) and 0.066 (±0.010) QALYs for patients receiving standard care. NPWT may be slightly more costly and more effective than standard care, with estimated incremental cost-effectiveness ratios (ICERs) of AU$1347 (95%CI dominant- $41,873) per SSI prevented and AU$42,340 (95%CI dominant- $884,019) per QALY gained. However, there was considerable uncertainty around these estimates. NPWT may be cost-effective in the prophylactic treatment of surgical wounds following elective caesarean section in obese women. Larger trials could clarify the cost-effectiveness of NPWT as a prophylactic treatment for SSI. Sensitive capture of QALYs and cost offsets will be important given the high level of uncertainty around the point estimate cost-effectiveness ratio which was close to conventional thresholds.

  7. The Angelina Jolie Effect in Jewish Law: Prophylactic Mastectomy and Oophorectomy in BRCA Carriers

    Sharon Galper Grossman

    2015-10-01

    Full Text Available Background: Following the announcement of actress Angelina Jolie’s prophylactic bilateral mastectomies and subsequent prophylactic oophorectomy, there has been a dramatic increase in interest in BRCA testing and prophylactic surgery. Objective: To review current medical literature on the benefits of prophylactic mastectomy and oophorectomy among BRCA-positive women and its permissibility under Jewish law. Results: Recent literature suggests that in BRCA-positive women who undergo prophylactic oophorectomy the risk of dying of breast cancer is reduced by 90%, the risk of dying of ovarian cancer is reduced by 95%, and the risk of dying of any cause is reduced by 77%. The risk of breast cancer is further reduced by prophylactic mastectomy. Prophylactic oophorectomy and prophylactic mastectomy pose several challenges within Jewish law that call into question the permissibility of surgery, including mutilation of a healthy organ, termination of fertility, self-wounding, and castration. A growing number of Jewish legal scholars have found grounds to permit prophylactic surgery among BRCA carriers, with some even obligating prophylactic mastectomy and oophorectomy. Conclusion: Current data suggest a significant reduction in mortality from prophylactic mastectomy and oophorectomy in BRCA carriers. While mutilation of healthy organs is intrinsically forbidden in Jewish law, the ability to preserve human life may contravene and even mandate prophylactic surgery.

HPV-related diseases were of interest: cervical cancer, cervical intraepithelial neoplasia, and genital warts. The two strategies used were 1) current practice and 2) prophylactic quadrivalent vaccine against HPV types 6, 11, 16, and 18. We developed a Markov simulation model to evaluate the incremental cost-effectiveness ratio of prophylactic HPV vaccine. Women transition through a model either healthy or developing HPV or its related diseases, or die from cervical cancer or from other causes according to transitional probabilities under the Thai health-care context. Costs from a provider perspective were obtained from King Chulalongkorn Memorial Hospital. Costs and benefits were discounted at 3% annually. Compared with no prophylactic HPV vaccine, the incremental cost-effectiveness ratio was 160,649.50 baht per quality-adjusted life-year. The mortality rate was reduced by 54.8%. The incidence of cervical cancer, cervical intraepithelial neoplasia grade 1, cervical intraepithelial neoplasia grade 2/3, and genital warts was reduced by up to 55.1%. Compared with commonly accepted standard thresholds recommended by the World Health Organization Commission on Macroeconomics and Health, the nationwide coverage of HPV vaccination in girls is likely to be cost-effective in Thailand.

    Objective: To discuss the effect and safety of transcatheter angiographic embolization (TAE)for managing massive obstetric haemorrhage. Methods: 17 cases of obstetric massive haemorrhage or with haemorrhage tendency were treated with TAE. Among them 14 cases had haemorrhage already, including 10 cases after abortion, caesarean section or normal labor and other 4 of hydatidiform mole. 3 cases with obstetric haemorrhage tendency included 2 cases of placenta praevia and 1 case of cervical pregnancy. Selective catheterization into bilateral uterine arteries or internal iliac arteries for DSA, showed the cause and location of the haemorrhage and then embolized with gelfoam sponge chips (1-3 mm) or Polyvinyl Alcohol(PVA); and part of the cases with MTX through uterine arterial perfusion. Results: The successful rate of catheterization was 100%. The achievement in 14 cases showed no active haemorrhage immediately after the procedure and no vaginal bleeding after 1-5 days. In 3 prophylactic cases before abortion or uterine curettage, obstetric massive haemorrhage occurred in 1 case, but not so in other 2 cases. Conclusions: TAE is an effective treatment for obstetric massive haemorrhage, with the advantages of minimal trauma, fast and definite treating effect and less complications. Prophylactical application for high risk patients can reduce the bleeding and mortality. (authors)

    Full Text Available Introduction: Wound infection is one of the most common complications of surgical procedures.At present, different procedures are used to reduce wound infection including prophylactic antibiotics.Since laparoscopy controls the most sources of wound infection such as mechanical factors, the role ofprophylactic antibiotic therapy may be in doubt. In this study, we evaluated the antibiotic effects inprevention of wound infection in laparoscopic cholecystectomy.Methods and Materials: In this double-blind clinical trial study, patients who were candidate forlaparoscopic cholecystectomy were divided randomly into two groups: antibiotic receivers (38patients and placebo (Normal Saline receivers (32 patients group. The patients were visited in 24hours, 4-7, 10-15 and 30 days after surgery for wound infection and then 2 groups compared.Results: The study showed that there were no significant differences between two groups withrespect to age, body mass index and smoking. In addition, no wound infection was observed in first 24hours, 4-7, 10-15 and 30 days after operation in both groups.Conclusion: The findings showed that prophylactic antibiotic therapy in laparoscopiccholecystectomy has no effect on the incidence of wound infection. Therefore, it is suggested thatprophylactic antibiotic therapy does not use in laparoscopic cholecystectomy because of producingantibiotic resistance, unnecessary complications and also reducing economical costs.

    Prophylactic ankle bracing is commonly used during physical activity. Understanding how bracing affects body mechanics is critically important when discussing both injury prevention and sport performance. The purpose is to determine if ankle bracing affects lower extremity mechanics during the Landing Error Scoring System test (LESS) and Sage Sway Index (SSI). Thirty physically active participants volunteered for this study. Participants completed the LESS and SSI in both a braced and unsupported conditions. Total errors were recorded for the LESS. Total errors and time (seconds) were recorded for the SSI. The Wilcoxon signed-rank test was utilized to evaluate any differences between the brace conditions for each dependent variable. A priori alpha level was set at pWilcoxon signed-rank test yielded no significant difference between the braced and unsupported conditions for the LESS (Z=-0.35, p=0.72), SSI time (Z=-0.36, p=0.72), or SSI Errors (Z=-0.37, p=0.71). Ankle braces had no effect on subjective clinical assessments of lower extremity alignment or postural stability. Utilization of a prophylactic support at the ankle did not substantially alter the proximal components of the lower kinetic chain. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available AIMS AND OBJECTIVE: This prospective double blind randomized study was conducted to compare: 1. The efficacy and safety of prophylactic administration of Metoclopramide versus Ondansetron in the control of postoperative nausea and vomiting in patients receiving intravenous Tr amadol as postoperative analgesic. 2. To study the incidence of post operative nausea and vomiting with IV bolus Tramadol. METHODS: 90 patients ASA grade I and II, age 18 - 60 years, posted for hernia, hydrocele and other peripheral lower limb surgeries under subarachnoid block were selected . Patients were randomly allocated into three groups of thirty each. All surgeries were performed under subarachnoid block and received IV Tramadol 100 m g 8 hourly for 24 hours as post - operative analgesic. Group N received no prophylactic antiemetic. Group M received 10 mg Metoclopramide 12 hourly. Group O received 4 mg Ondansetron 12 hourly. Vital signs, nausea, vomiting, pain, sedation, need for rescue a ntiemetic, rescue analgesic and adverse effects were recorded for 24 hours. RESULTS: Ondansetron group (Group O significantly reduced the incidence of PONV as compared to Metoclopramide (Group M and no antiemetic group (Group N .But Metoclopramide was fo und to be not significantly effective in controlling PONV in patients receiving Tramadol as analgesic. None of the patients in Group O required rescue antiemetic as compared to 13.3% patients in Group M and 26.7% patients in Group N. There was statisticall y no significant difference between the 3 groups with respect to requirement of rescue analgesic. No major adverse effects were observed which can be attributed to either Metoclopramide or Ondansetron. CONCLUSION: Ondansetron was more effective than Metoclopramide in controlling PONV, in patients receiving IV Tramadol as post-operative analgesia

    Although surgery is recommended after two or more attacks of uncomplicated diverticulitis, the optimal timing for surgery in terms of cost-effectiveness is unknown. A Markov model was used to compare the costs and outcomes of performing surgery after one, two, or three uncomplicated attacks in 60-year-old hypothetical cohorts. Transition state probabilities were assigned values using published data and expert opinion. Costs were estimated from Medicare reimbursement rates. Surgery after the third attack is cost saving, yielding more years of life and quality adjusted life years at a lower cost than the other two strategies. The results were not sensitive to many of the variables tested in the model or to changes made in the discount rate (0-5%). In conclusion, performing prophylactic resection after the third attack of diverticulitis is cost saving in comparison to resection performed after the first or second attacks and remains cost-effective during sensitivity analysis.

    Develop a risk prediction model for severe intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI). Prospectively collected data of infants with birth weight 500 to 1249 g born between 2001 and 2010 in centers from the Neocosur Network were used. Forward stepwise logistic regression model was employed. The model was tested in the 2011 cohort and then applied to the population of VLBWI that received prophylactic indomethacin to analyze its effect in the risk of severe IVH. Data from 6538 VLBWI were analyzed. The area under ROC curve for the model was 0.79 and 0.76 when tested in the 2011 cohort. The prophylactic indomethacin group had lower incidence of severe IVH, especially in the highest-risk groups. A model for early severe IVH prediction was developed and tested in our population. Prophylactic indomethacin was associated with a lower risk-adjusted incidence of severe IVH.

    Many polishing protocols have been evaluated in vitro for their effect on the surface roughness of restorative materials. These results have been useful in establishing protocols for in vivo application. However, limited research has focused on the subsequent care and maintenance of esthetic restorations following their placement. This investigation evaluated the effect of five polishing protocols that could be implemented at recall on the surface roughness of five direct esthetic restorative materials. Specimens (n=25) measuring 8 mm diameter x 3 mm thick were fabricated in an acrylic mold using five light-cured resin-based materials (hybrid composite, microfilled composite, packable composite, compomer and resin-modified glass ionomer). After photopolymerization, all specimens were polished with Sof-Lex Disks to produce an initial (baseline) surface finish. All specimens were then polished with one of five prophylactic protocols (Butler medium paste, Butler coarse paste, OneGloss, SuperBuff or OneGloss & SuperBuff). The average surface roughness of each treated specimen was determined from three measurements with a profilometer (Surface 1). Next, all specimens were brushed 60,000 times at 1.5 Hz using a brush-head force of 2 N on a Manly V-8 cross-brushing machine in a 50:50 (w/w) slurry of toothpaste and water. The surface roughness of each specimen was measured after brushing (Surface 2) followed by re-polishing with one of five protocols, then final surface roughness values were determined (Surface 3). The data were analyzed using repeated measures ANOVA. Significant differences (p=0.05) in surface roughness were observed among restorative materials and polishing protocols. The microfilled and hybrid resin composite yielded significantly rougher surfaces than the other three materials following tooth brushing. Prophylactic polishing protocols can be used to restore a smooth surface on resin-based esthetic restorative materials following simulated tooth

    Inflammation plays a role in the pathophysiology of depression. Sulforaphane (SFN), an isothiocyanate compound derived from broccoli, is a potent activator of the NF-E2-related factor-2 (Nrf2), which plays a role in inflammation. In this study, we examined whether the prevention effects of SFN in lipopolysaccharide (LPS) induced depression-like behavior in mice. Pretreatment with SFN significantly blocked an increase in the serum tumor necrosis factor-α (TNF-α) level and an increase in microglial activation of brain regions after a single administration of LPS (0.5 mg/kg). Furthermore, SFN significantly potentiated increased serum levels of IL-10 after LPS administration. In the tail-suspension test and forced swimming test, SFN significantly attenuated an increase of the immobility time after LPS administration. In addition, SFN significantly recovered to control levels for LPS-induced alterations in the proteins such as brain-derived neurotrophic factor, postsynaptic density protein 95 and AMPA receptor 1 (GluA1) and dendritic spine density in the brain regions. Finally, dietary intake of 0.1% glucoraphanin (a glucosinolate precursor of SFN) food during the juvenile and adolescence could prevent the onset of LPS-induced depression-like behaviors and dendritic spine changes in the brain regions at adulthood. In conclusion, these findings suggest that dietary intake of SFN-rich broccoli sprout has prophylactic effects on inflammation-related depressive symptoms. Therefore, supplementation of SFN-rich broccoli sprout could be prophylactic vegetable to prevent or minimize the relapse by inflammation in the remission state of depressed patients.

    The ulcerogenic potential of dopamine antagonists and L-NAME in rats provides unresolved issues of anti-emetic neuroleptic application in both patients and experimental studies. Therefore, in a 1-week study, we examined the pressures within the lower oesophageal and the pyloric sphincters in rats [assessed manometrically (cm H 2 O)] after dopamine neuroleptics/prokinetics, L-NAME, L-arginine and stable gastric pentadecapeptide BPC 157 were administered alone and/or in combination. Medication (/kg) was given once daily intraperitoneally throughout the 7 days, with the last dose at 24 h before pressure assessment. Given as individual agents to healthy rats, all dopamine antagonists (central [haloperidol (6.25 mg, 16 mg, 25 mg), fluphenazine (5 mg), levomepromazine (50 mg), chlorpromazine (10 mg), quetiapine (10 mg), olanzapine (5 mg), clozapine (100 mg), sulpiride (160 mg), metoclopramide (25 mg)) and peripheral(domperidone (10 mg)], L-NAME (5 mg) and L-arginine (100 mg) decreased the pressure within both sphincters. As a common effect, this decreased pressure was rescued, dose-dependently, by BPC 157 (10 µg, 10 ng) (also note that L-arginine and L-NAME given together antagonized each other's responses). With haloperidol, L-NAME worsened both the lower oesophageal and the pyloric sphincter pressure, while L-arginine ameliorated lower oesophageal sphincter but not pyloric sphincter pressure, and antagonized L-NAME effect. With domperidone, L-arginine originally had no effect, while L-NAME worsened pyloric sphincter pressure. This effect was opposed by L-arginine. All these effects were further reversed towards a stronger beneficial effect, close to normal pressure values, by the addition of BPC 157. In addition, NO level was determined in plasma, sphincters and brain tissue. Thiobarbituric acid reactive substances (TBARS) were also assessed. Haloperidol increased NO levels (in both sphincters, the plasma and brain), consistently producing increased

    This paper reports prescribing patterns for prophylaxis of chemotherapy-induced nausea and vomiting (CINV) after highly or moderately emetogenic chemotherapy (HEC or MEC) for cancer in six Asia Pacific countries. In a prospective noninterventional study, 31 sites in Australia, China, India, Singapore, South Korea, and Taiwan recorded details of CINV prophylaxis for the acute phase (first 24 h) and delayed phase (days 2-5) after single-day HEC or MEC for adult patients. Additional information on CINV prophylactic medications was collected from 6-day patient diaries. Primary antiemetic therapies were defined as corticosteroids, the 5-hydroxytryptamine-3 receptor antagonists (5HT3-RAs), and neurokinin-1 receptor antagonists (NK1-RAs). Evaluable patients in cycle 1 numbered 648 (318 [49%] HEC and 330 [51%] MEC) of mean (SD) age of 56 (12) years, including 58% women. For the acute phase after HEC, overall (and country range), 96% (91-100%) of patients received a 5HT3-RA, 87% (70-100%) a corticosteroid, and 43% (0-91%) an NK1-RA. CINV prophylaxis for the HEC delayed phase was more variable: including 22% (7-65%) 5HT3-RA, 52% (12-93%) corticosteroid, and 46% (0-88%) NK1-RA. For the MEC acute phase, 97% (87-100%) of patients received 5HT3-RA and 86% (73-97%) a corticosteroid. For the MEC delayed phase, 201 patients (61%) received a primary antiemetic, including 5HT3-RA (41%), corticosteroid (37%), and/or NK1-RA (4%). The 5HT3-RAs were prescribed consistently in all countries, while prescribing of other antiemetic therapies was variable, and corticosteroids were under-prescribed for CINV prophylaxis, particularly in the delayed phase.

    The anti-emetic effects of 40 extracts made from 12 traditional Chinese herbal drugs were examined. Ten extracts inhibited emesis induced by copper sulfate pentahydrate; all were administered orally, and one extract inhibited emesis induced by apomorphine hydrochloride given to leopard and ranid frogs. Taraxasteryl palmitate and acetate, bigelovin and dihydrobigelovin were isolated from the CHCl(3) extract of Inula linariaefolia flowers, and identified as the active antiemetic agents when emesis was induced by copper sulfate. In addition, chlorogenic acid was isolated from the MeOH extract as an anti-emetic principle for the emesis induced by apomorphine hydrochloride. Rengyol, phillyrin and rutin were isolated from the MeOH extract of Forsythia suspensa fruits and identified as the inhibitors of emesis induced by copper sulfate pentahydrate.

    To evaluate the effect of prophylactic epiphyseodesis of the greater trochanter in Perthes' disease, 62 children with unilateral Perthes' disease who underwent trochanteric epiphyseodesis combined with varus osteotomy of the femur during the active stage of the disease (mean age at surgery: 8.4 y) and 20 controls were followed up until skeletal maturity. On radiographs taken at skeletal maturity, the articulo-trochanteric distance, the center-trochanteric distance, the length of the abductor lever arm, the neck-shaft angle, the radius of the femoral head, and the Reimer's migration index of normal and affected hips were measured. The shape of the femoral head was assessed according to the criteria of Mose. The range of hip motion, the strength of hip abduction, and limb lengths were measured and the Trendelenburg sign was elicited. The mean values of articulo-trochanteric distance and center-trochanteric distance were greater and the frequency of a positive Trendelenburg sign was less in children who had undergone trochanteric epiphyseodesis than in children who had no surgery (P<0.01). Trochanteric epiphyseodesis achieved optimal trochanteric growth arrest in 60% of operated children; the procedure was not effective in 30%, and in 10% of children there was overcorrection. Logistic regression analysis showed that the size of the femoral head at healing and the age at surgery were variables that significantly influenced the effectiveness of trochanteric growth arrest. At skeletal maturity, the mean shortening of the affected limb in operated children was 0.44 cm (SD 0.68 cm), whereas that of non-operated children was 0.86 cm (SD 0.78 cm) (P<0.05). The range of motion of the hip was excellent and there were no significant differences in the range of motion among children with optimal correction, under-correction, and overcorrection. A probability curve plotted on the basis of a logistic regression model suggests that effective trochanteric arrest may be achieved in a

    To determine the effect of prophylactic antibiotics on endometrial and endocervical microflora upon diagnosis of postcesarean endometritis. The medical records of patients enrolled in open-label comparative trials of therapeutic antibiotics for postpartum endometritis between 1989 and 1994 were reviewed (n = 682). Endometritis was diagnosed by a standard definition that included fever and localizing signs. Endometrial cultures were obtained by a sheathed injection/aspiration technique. Aerobes and anaerobes were isolated by standard microbiologic techniques. The primary outcome, endometrial and endocervical microflora, was compared in women who received intravenous ampicillin (2 g every 6 hours for 1-3 doses), cephalosporin (2 g every 6 hours for 1-3 doses), or no prophylaxis. Secondary outcomes included the cure of endometritis and the prevalence of wound infection in the three groups. Four hundred sixty-five of 682 patients (67%) had a cesarean delivery. One hundred fifty-one patients received ampicillin prophylaxis, 100 patients received cefazolin prophylaxis, 18 patients received extended-spectrum antibiotics, and 196 patients received no prophylaxis. Patients who received cefazolin prophylaxis had a significant increase in enterococcus (P women who develop endometritis. Whereas these changes had no effect on endometritis cure rate (power > 80%), the association between cefazolin prophylaxis followed by an extended-spectrum cephalosporin and wound infection may warrant caution against the use of the combination.

    A double-blind, randomized controlled trial was conducted in an endemic focus for Schistosoma mansoni in Kafr El-Sheikh Governorate, Northern Nile Delta, Egypt, to evaluate the prophylactic effect of artemether (ART) given in conjunction with praziquantel (PZQ). The study encompassed 913 primary school children randomly assigned to two treatment groups PZQ/ART and PZQ/ART-placebo. At baseline, both groups received 40 mg/kg body weight of PZQ twice four weeks apart, after which one group received 6 mg/kg body weight of ART every 3 weeks in 5 cycles during the transmission season and the other group received ART-placebo. At the end of the study, prevalence of infection among the PZQ/ART was approximately half that of the PZQ/ART-placebo group, i.e. 6.7% versus 11.6%, and incidence of new infections for the PZQ/ART was 2.7% versus 6.5% for the PZQ/ART-placebo. In conclusion, PZQ/ART combined therapy might be considered as an adjunct measure against human schistosomiasis, by specifically reducing transmission and therefore contribute to disease elimination.

    To investigate the effects of a prophylactic knee brace on knee joint kinetics and kinematics during netball specific movements. Repeated measures. Laboratory. Twenty university first team level female netball players. Participants performed three movements, run, cut and vertical jump under two conditions (brace and no-brace). 3-D knee joint kinetics and kinematics were measured using an eight-camera motion analysis system. Knee joint kinetics and kinematics were examined using 2 × 3 repeated measures ANOVA whilst the subjective ratings of comfort and stability were investigated using chi-squared tests. The results showed no differences (p > 0.05) in knee joint kinetics. However the internal/external rotation range of motion was significantly (p < 0.05) reduced when wearing the brace in all movements. The subjective ratings of stability revealed that netballers felt that the knee brace improved knee stability in all movements. Further study is required to determine whether reductions in transverse plane knee range of motion serve to attenuate the risk from injury in netballers. Copyright © 2016 Elsevier Ltd.

    Sinusoidal obstruction syndrome (SOS) is a serious complication of hematopoietic stem cell transplantation (HSCT), with a mortality rate of up to 90%. We report our experience on the use of defibrotide for SOS prophylaxis in HSCT. We retrospectively reviewed data of 49 patients who received defibrotide as SOS prophylaxis during the course of HSCT at the National Cancer Center, Goyang, Korea, between August 2005 and July 2008. Thirty-four patients (69.4%) were classified as a high-risk group for developing SOS. Defibrotide was well-tolerated, without any grade 3 or 4 toxicity. The median value of maximum total bilirubin within 100 days after HSCT was within the normal range. SOS was diagnosed in only 1 patient, who underwent autologous HSCT due to relapsed medulloblastoma. There was no day 100 treatment-related mortality in our study. Defibrotide appears to be a safe prophylaxis for SOS. This study suggests that it could be effective to use prophylactic defibrotide in advance to improve HSCT outcomes in patients at risk of SOS.

    The narrow field of non-controversial indications concerning the application of digitalis glycosides is pointed out. Problems of routine digitalization of older patients not suffering from cardiac insuffiency are discussed with special regard to preparing them for operations. Up to now, from the viewpoint of anaesthesiologists no benefits of prophylactic digitalization have been found. In a retrospective computerized study, clinical hemodynamic parameters during introduction of anaesthesia have been investigated by means of anaesthetic data recorded during three years. Nondigitalized patients older than fifty years showed satisfactory cardiac functions, whereas prophylactically digitalized patients--compared with the control group--have been treated with plasma expanders earlier and at a double rate. Furthermore, higher heart frequencies and greater tendency to arrythmias were observed. Consequently, prophylactic digitalization cannot be recommended in general.

    Few studies have evaluated the long-term effects of prophylactic ankle-brace use during a sport season. To determine the effects of prophylactic ankle-brace use during a high school basketball season on dynamic postural control and functional tests. Prospective repeated-measures design. High school athletic facility. 21 healthy high school basketball athletes (13 girls, 8 boys). The order of testing was randomized using the Star Excursion Balance Test (SEBT) for posteromedial (PM), medial (M), and anteromedial (AM) directions and 3 functional tests (FT) consisting of the single-leg crossover hop, single-leg vertical jump, and the single-leg 6-m hop for time at pre-, mid-, and postseason. After pretesting, the ankle brace was worn on both limbs during the entire 16-wk competitive basketball season. SEBT for PM, M, and AM and 3 single-leg FTs. Dynamic postural control using the SEBT and the 3 FTs improved over time, notably from pretest to posttest. The left limb was different from the right limb during the single-leg vertical jump. Effect sizes were large for pretest to posttest for the 3 SEBT directions and 2 of the 3 FTs. The 16-wk basketball prophylactic ankle-brace intervention significantly improved dynamic postural control and single-limb FTs over time.

    Probiotics are live bacteria that confer health benefits to the host physiology. Although protective role of probiotics have been reported in diverse diseases, no information is available whether probiotics can modulate neuromuscular immune disorders. We have recently demonstrated that IRT5 probiotics, a mixture of 5 probiotics, could suppress diverse experimental disorders in mice model. In this study we further investigated whether IRT5 probiotics could modulate the progression of experimental autoimmune myasthenia gravis (EAMG). Myasthenia gravis (MG) is a T cell dependent antibody mediated autoimmune disorder in which acetylcholine receptor (AChR) at the neuromuscular junction is the major auto-antigen. Oral administration of IRT5 probiotics significantly reduced clinical symptoms of EAMG such as weight loss, body trembling and grip strength. Prophylactic effect of IRT5 probiotics on EMAG is mediated by down-regulation of effector function of AChR-reactive T cells and B cells. Administration of IRT5 probiotics decreased AChR-reactive lymphocyte proliferation, anti-AChR reactive IgG levels and inflammatory cytokine levels such as IFN-γ, TNF-α, IL-6 and IL-17. Down-regulation of inflammatory mediators in AChR-reactive lymphocytes by IRT5 probiotics is mediated by the generation of regulatory dendritic cells (rDCs) that express increased levels of IL-10, TGF-β, arginase 1 and aldh1a2. Furthermore, DCs isolated from IRT5 probiotics-fed group effectively converted CD4+ T cells into CD4+Foxp3+ regulatory T cells compared with control DCs. Our data suggest that IRT5 probiotics could be applicable to modulate antibody mediated autoimmune diseases including myasthenia gravis. PMID:23284891

    Although antiemetic management in cancer therapy has improved, chemotherapy-induced nausea and vomiting remain common and troubling adverse events. Chemotherapeutic agents are classified based on their emetogenic effects, and appropriate antiemetics are recommended according to this categorization. Chemotherapy categorized as moderately emetogenic is associated with a wide spectrum of emetic risks. Combined anthracycline and cyclophosphamide regimens have been recently reclassified as highly emetogenic chemotherapy regimen. This review focuses on antiemetic pharmacotherapy in patients receiving non-anthracycline and cyclophosphamide-based moderately emetogenic chemotherapy regimens. Combination therapy with a 5-hydroxytryptamine-3 receptor agonist, preferably palonosetron, and dexamethasone is the standard therapy in moderately emetogenic chemotherapy, although triple therapy with add-on neurokinin-1 receptor antagonist is used as an alternative treatment strategy. Among moderately emetogenic chemotherapy regimens, carboplatin-containing chemotherapy has considerable emetic potential, particularly during the delayed phase. However, the additional of a neurokinin-1 receptor antagonist to the standard antiemetic therapy prevents carboplatin-induced nausea and vomiting. For regimens including oxaliplatin, the benefit of adding neurokinin-1 receptor antagonist requires further clarification.

    We have reported previously that the anti-emetic efficacy of single agent 5HT3 antagonists is not maintained when analysed with the measurement of cumulative probabilities. Presently, the most effective anti-emetic regimen is a combination of a 5HT3 antagonist plus dexamethasone. We, therefore, assessed the sustainment of efficacy of such a combination in 125 patients, scheduled to receive cisplatin > or = 70 mg m(-2) either alone or in combination with other cytotoxic drugs. Anti-emetic therapy was initiated with 10 mg of dexamethasone and 3 mg of granisetron intravenously, before cisplatin. On days 1-6, patients received 8 mg of dexamethasone and 1 mg of granisetron twice daily by oral administration. Protection was assessed during all cycles and calculated based on cumulative probability analyses using the method of Kaplan-Meier and a model for transitional probabilities. Irrespective of the type of analysis used, the anti-emetic efficacy of granisetron/dexamethasone decreased over cycles. The initial complete acute emesis protection rate of 66% decreased to 30% according to the method of Kaplan-Meier and to 39% using the model for transitional probabilities. For delayed emesis, the initial complete protection rate of 52% decreased to 21% (Kaplan-Meier) and to 43% (transitional probabilities). In addition, we observed that protection failure in the delayed emesis period adversely influenced the acute emesis protection in the next cycle. We conclude that the anti-emetic efficacy of a 5HT3 antagonist plus dexamethasone is not maintained over multiple cycles of highly emetogenic chemotherapy, and that the acute emesis protection is adversely influenced by protection failure in the delayed emesis phase.

    Cardiac implantable electronic device (CIED) hematomas are associated with many adverse outcomes. We examined the incidence and risk factors associated with hematoma formation post-CIED implantation, and explored the preventative effect of prophylactic pressure bandaging (PPB) in a large tertiary center. 1,091 devices were implanted during October 2011-December 2014. Clinically significant hematomas (CSH) were those that necessitated prolonged admission, including those due to reoperation, and clinically suspicious hematomas were swellings noted by medical/nursing staff. We screened for variables affecting hematoma incidence prior to conducting multivariate logistic regression analyses, one for all hematomas and one for CSH. 61 hematomas were identified (5.6% of patients), with 12 of those clinically significant (1.1% of patients). Factors significantly increasing the odds of developing any hematoma were stage 2 (odds ratio [OR] = 2.93, 95% confidence interval [CI] [1.08-7.94], P = 0.034) and 3 chronic kidney disease (CKD) (OR = 3.39 [1.20-9.56], P = 0.021), unfractionated heparin/therapeutic enoxaparin (OR = 3.15 [1.22-8.14], P = 0.018), and dual antiplatelets-aspirin + clopidogrel (OR = 2.95 [1.14-7.65], P = 0.026) + other combinations. Body Mass index (BMI) 25.0-29.9 (OR 0.52 [0.28-0.98], P = 0.044) and >30 were associated with decreased hematoma risk (OR 0.43 [0.20-0.91], P = 0.028). Factors significant for CSH formation were unfractionated heparin/therapeutic enoxaparin (OR = 9.55 [1.83-49.84], P = 0.007) and aspirin + clopidogrel (OR = 7.19 [1.01-50.91], P = 0.048). PPB nonsignificantly increased the odds of total hematoma development (OR = 1.53 [0.87-2.69], P = 0.135), and reduced CSH (OR = 0.67 [0.18-2.47], P = 0.547). Heparin and dual antiplatelet use remain strong predictors of overall hematoma formation. CKD is a comparatively moderate predictor. BMI > 25 may decrease the risk of hematoma formation. PPB had nonsignificant effects on hematoma development

    To study the relationship of chemoprophylaxis and other factors with the occurrence of acute, clinical, postoperative macular edema. Retrospective cohort study. The drug regimens consisted of postoperative topical prednisolone acetate (PA) alone or with a nonsteroidal anti-inflammatory drug (NSAID) or intraoperative subconjunctival injection of 2 mg triamcinolone acetonide (TA) alone. Patients undergoing phacoemulsification at Kaiser Permanente, Diablo Service Area, Northern California, from 2007 through 2013. We identified incident macular edema diagnoses that had been recorded 5 to 120 days after phacoemulsification with visual acuity 20/40 or worse and evidence of macular thickening by optical coherence tomography. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained from logistic regression analysis, conditioned on the surgeon and adjusted for year, patient age and race, diabetic retinopathy status, other ocular comorbidities, systemic comorbidities, and posterior capsular rupture status. Incident rates of acute, clinical, postoperative macular edema. We confirmed 118 cases among 16 070 cataract surgeries (incidence, 0.73%). Compared with PA alone, the OR for the relationship of macular edema with PA+NSAID was 0.45 (95% CI, 0.21-0.95) and that for TA injection was 1.21 (95% CI, 0.48-3.06). The frequency of intraocular pressure spikes of 30 mmHg or more between postoperative days 16 and 45 was 0.6% in the topical PA group, 0.3% in the topical PA+NSAID group (P = 0.13), and 0.8% for the TA group (P = 0.52). Black race was associated with a risk of macular edema (OR, 2.86; 95% CI, 1.41-5.79). Adding a prophylactic NSAID to PA treatment was associated with a reduced risk of macular edema with visual acuity of 20/40 or worse. The risk and safety of TA injection were similar to those of PA alone. Further research is needed on the prognostic significance of postoperative macular edema, the role of prophylaxis, the risk among black people, and the

    Full Text Available There has been much debate on how prophylactic ankle supports (PASs may influence the vertical ground reaction force (vGRF during landing. Therefore, the primary aims of this meta-analysis were to systematically review and synthesize the effect of PASs on vGRF, and to understand how PASs affect vGRF peaks (F1, F2 and the time from initial contact to peak loading (T1, T2 during landing. Several key databases, including Scopus, Cochrane, Embase, PubMed, ProQuest, Medline, Ovid, Web of Science, and the Physical Activity Index, were used for identifying relevant studies published in English since inception to April 1, 2015. The computerized literature search and cross-referencing the citation list of the articles yielded 3,993 articles. Criteria for inclusion required that 1 the study was conducted on healthy adults; 2 the subject number and trial number were known; 3 the subjects performed landing with and without PAS; 4 the landing movement was in the sagittal plane; 5 the comparable vGRF parameters were reported; and 6 the F1 and F2 must be normalized to the subject’s body weight. After the removal of duplicates and irrelevant articles, 6, 6, 15 and 11 studies were respectively pooled for outcomes of F1, T1, F2 and T2. This study found a significantly increased F2 (.03 BW, 95% CI: .001, .05 and decreased T1 (-1.24 ms, 95% CI: -1.77, -.71 and T2 (-3.74 ms, 95% CI: -4.83, -2.65 with the use of a PAS. F1 was not significantly influenced by the PAS. Heterogeneity was present in some results, but there was no evidence of publication bias for any outcome. These changes represented deterioration in the buffering characteristics of the joint. An ideal PAS design should limit the excessive joint motion of ankle inversion, while allowing a normal range of motion, especially in the sagittal plane.

    At the beginning of the 80's the Italian Group for Clinical Research (G.O.I.R.C.) identified chemotherapy-induced nausea and vomiting as one of the most distressing adverse events, and decided to plan and execute clinical trials on antiemetics in order to reduce this negative impact on patients. Therefore, some consecutive double-blind randomized trials were conducted on cisplatin-treated patients. The first was a dose-finding study on four different high-doses of domperidone, followed by a study comparing two different high-doses of metoclopramide, and a study comparing the addition of a corticosteroid to high-dose metoclopramide with respect to metoclopramide alone. Finally, a study demonstrating that a combination of a higher dose of metoclopramide (3 mg/kg x 2) plus dexamethasone and diphenhydramine was significantly superior with respect to a lower dose of metoclopramide (1 mg/kg x 4) combined with methylprednisolone was carried out. With the introduction of the 5-HT3 receptor antagonists the interest for antiemetic therapy increased and other Italian gynecological and medical oncology centres became involved in the antiemetic research. The Italian Group for Antiemetic Research was formed in 90's and its first study demonstrated the superiority of a combination of a 5-HT3 receptor antagonist plus dexamethasone with respect to the standard three drug combination of high doses of metoclopramide in the prevention of cisplatin-induced acute emesis. In the following years, the Group contributed to the identification of the best antiemetic prophylaxis for acute emesis induced by moderately emetogenic chemotherapy, and for delayed emesis induced by cisplatin. Also a drug utilization review on antiemetics in clinical practice has recently been carried out. Today, the interest of the Group is concentrated in studying the optimal antiemetic prophylaxis for delayed emesis induced by moderately emetogenic chemotherapy. The rules always followed by the Italian Group for

    Purpose: The purpose of the present study was to evaluate the prophylactic effect of hyperbaric oxygen (HBO) therapy for radiation-induced brain injury in patients with brain metastasis treated with stereotactic radiosurgery (SRS). Methods and Materials: The data of 78 patients presenting with 101 brain metastases treated with SRS between October 1994 and September 2003 were retrospectively analyzed. A total of 32 patients with 47 brain metastases were treated with prophylactic HBO (HBO group), which included all 21 patients who underwent subsequent or prior radiotherapy and 11 patients with common predictors of longer survival, such as inactive extracranial tumors and younger age. The other 46 patients with 54 brain metastases did not undergo HBO (non-HBO group). Radiation-induced brain injuries were divided into two categories, white matter injury (WMI) and radiation necrosis (RN), on the basis of imaging findings. Results: Radiation-induced brain injury occurred in 5 lesions (11%) in the HBO group (2 WMIs and 3 RNs) and in 11 (20%) in the non-HBO group (9 WMIs and 2 RNs). The WMI was less frequent for the HBO group than for the non-HBO group (p = 0.05), although multivariate analysis by logistic regression showed that WMI was not significantly correlated with HBO (p = 0.07). The 1-year actuarial probability of WMI was significantly better for the HBO group (2%) than for the non-HBO group (36%) (p < 0.05). Conclusions: The present study showed a potential value of prophylactic HBO for Radiation-induced WMIs, which justifies further evaluation to confirm its definite benefit

    1993-01-01

    Between 1967 and 1988, 102 patients with Stage T1-2N0 squamous cell carcinoma of the tongue were treated with uneven fractional irradiation therapy (intra-oral electron beam irradiation with and without prophylactic ipsilateral upper neck irradiation at the Dept. of Radiology, Nihon University School of Medicine. Of 102 primary lesions, 89 cases were controlled with this therapy. In this study, these 89 cases were investigated in order to analyze the prophylactic effect of upper neck irradiation. Of the 89 patients, 42 received only intra-oral electron beam irradiation, while the remaining 47 received a combination of intra-oral electron beam irradiation and prophylactic irradiation to the ipsilateral upper neck. Twenty three of the 89 (25.8%) developed metastasis to the neck after the radiotherapy. A breakdown of these 23 cases reveals that 3/21 (14.3%) received 40-50 Gy to the neck, 9/26 (34.6%) received 20-40 Gy to the neck, and 11/42 (26.2%) received no irradiation to the neck (p<0.05 between first and second groups, and between first and third groups). The neck metastasis was classified into one of three categories based on the region in which it first appeared (ipsilateral upper neck, ipsilateral lower neck or contralateral neck). The first metastasis was seen in the ipsilateral upper neck, in the ipsilateral lower neck and in the contralateral neck in 17, 4 and 2 patients, respectively. In 1/19 who had received 40-50 Gy, in 5/21 who had received 20-40 Gy and in 11/42 who had not received neck irradiation the first metastasis appeared in the ipsilateral upper neck. The five year survival rate was 94%, 75% and 85% in the patients receiving 40-50 Gy, 20-40 Gy and no neck irradiation, respectively. These results suggest that prophylactic irradiation of 40-50 Gy to the ipsilateral upper neck might decrease the incidence of neck metastasis and slightly prolong survival time. (author)

    Anterior cruciate ligament (ACL) injuries commonly occur during landing maneuvers. Prophylactic knee braces were introduced to reduce the risk of ACL injuries, but their effectiveness is debated. We hypothesized that bracing would improve biomechanical factors previously related to the risk of ACL injuries, such as increased hip and knee flexion angles at initial contact and at peak vertical ground-reaction force (GRF), increased ankle plantar flexion angles at initial contact, decreased peak GRFs, and decreased peak knee extension moment. We also hypothesized that bracing would increase the negative power and work of the hip joint and would decrease the negative power and work of the knee and ankle joints. Controlled laboratory study. Three-dimensional motion and force plate data were collected from 8 female and 7 male recreational athletes performing double-leg drop landings from 0.30 m and 0.60 m with and without a prophylactic knee brace. GRFs, joint angles, moments, power, and work were calculated for each athlete with and without a knee brace. Prophylactic knee bracing increased the hip flexion angle at peak GRF by 5.56° (P knee flexion angle at peak GRF by 4.75° (P = .001), and peak hip extension moment by 0.44 N·m/kg (P knee and ankle. No differences in peak GRFs and peak knee extension moment were observed with bracing. The application of a prophylactic knee brace resulted in improvements in important biomechanical factors associated with the risk of ACL injuries. Prophylactic knee braces may help reduce the risk of noncontact knee injuries in recreational and professional athletes while playing sports. Further studies should investigate different types of prophylactic knee braces in conjunction with existing training interventions so that the sports medicine community can better assess the effectiveness of prophylactic knee bracing. © 2016 The Author(s).

  5. Mechanisms of Broad-Spectrum Antiemetic Efficacy of Cannabinoids against Chemotherapy-Induced Acute and Delayed Vomiting

    2010-09-01

    Full Text Available Chemotherapy-induced nausea and vomiting (CINV is a complex pathophysiological condition and consists of two phases. The conventional CINV neurotransmitter hypothesis suggests that the immediate phase is mainly due to release of serotonin (5-HT from the enterochromaffin cells in the gastrointestinal tract (GIT, while the delayed phase is a consequence of release of substance P (SP in the brainstem. However, more recent findings argue against this simplistic neurotransmitter and anatomical view of CINV. Revision of the hypothesis advocates a more complex, differential and overlapping involvement of several emetic neurotransmitters/modulators (e.g. dopamine, serotonin, substance P, prostaglandins and related arachidonic acid derived metabolites in both phases of emesis occurring concomitantly in the brainstem and in the GIT enteric nervous system (ENS [1]. No single antiemetic is currently available to completely prevent both phases of CINV. The standard antiemetic regimens include a 5-HT3 antagonist plus dexamethasone for the prevention of acute emetic phase, combined with an NK1 receptor antagonist (e.g. aprepitant for the delayed phase. Although NK1 antagonists behave in animals as broad-spectrum antiemetics against different emetogens including cisplatin-induced acute and delayed vomiting, by themselves they are not very effective against CINV in cancer patients. Cannabinoids such as D9-THC also behave as broad-spectrum antiemetics against diverse emetic stimuli as well as being effective against both phases of CINV in animals and patients. Potential side effects may limit the clinical utility of direct-acting cannabinoid agonists which could be avoided by the use of corresponding indirect-acting agonists. Cannabinoids (both phyto-derived and synthetic behave as agonist antiemetics via the activation of cannabinoid CB1 receptors in both the brainstem and the ENS emetic loci. An endocannabinoid antiemetic tone may exist since inverse CB1

    Full Text Available Background. Whether routine antifungal prophylaxis decreases posttransplantation fungal infections in patients receiving orthotopic liver transplantation (OLT remains unclear. This study aimed to determine the effectiveness of antifungal prophylaxis for patients receiving OLT. Patients and Methods. This is a retrospective analysis of a database at Chang Gung Memorial Hospital. We have been administering routine antibiotic and prophylactic antifungal regimens to recipients with high model for end-stage liver disease scores (>20 since 2009. After propensity score matching, 402 patients were enrolled. We conducted a multistate model to analyze the cumulative hazards, probability of fungal infections, and risk factors. Results. The cumulative hazards and transition probability of “transplantation to fungal infection” were lower in the prophylaxis group. The incidence rate of fungal infection after OLT decreased from 18.9% to 11.4% (p=0.052; overall mortality improved from 40.8% to 23.4% (p<0.001. In the “transplantation to fungal infection” transition, prophylaxis was significantly associated with reduced hazards for fungal infection (hazard ratio: 0.57, 95% confidence interval: 0.34–0.96, p=0.033. Massive ascites, cadaver transplantation, and older age were significantly associated with higher risks for mortality. Conclusion. Prophylactic antifungal regimens in high-risk recipients might decrease the incidence of posttransplant fungal infections.

    The prophylactic capacity of the RUTI® vaccine, based on fragmented cells of Mycobacterium tuberculosis, has been evaluated in respect to aerosol challenge with virulent bacilli. Subcutaneous vaccination significantly reduced viable bacterial counts in both lungs and spleens of C57Bl mice, when challenged 4 weeks after vaccination. RUTI® protected the spleen less than BCG. Following a 9 month vaccination-challenge interval, protection was observed for the lungs, but not for the spleen. Survival of infected guinea pigs was prolonged by vaccination given 5 weeks before challenge. Inoculations of RUTI® shortly after infection significantly reduced the viable bacterial counts in the lungs, when compared with infected control mice. Thus, vaccination by RUTI® has potential for both the prophylaxis and immunotherapy of tuberculosis.

    It is presumed that bilateral mastectomy is so far the most efficient way how to prevent development of breast carcinoma among BRCA positive patients. This mutilating intervention might be unacceptable for cosmetic reasons for most women. The purpose of this study was to determine the influence of prophylactic mastectomy on the quality of life of BRCA positive patients by comparing results of psychodiagnostic questionnaire methods before surgical intervention and after it. Our data set consisted of 25 BRCA positive healthy women and 19 BRCA positive women in remission. All these patients underwent a reconstructive surgical intervention after mastectomy. Age of patients was 38-55 years. The following questionnaires were used: Life Satisfaction Questionnaire by J. Fahrenberg, M. Myrtek and E. Brähler, Clinical analysis questionnaire by S. E. Kruge and R. B. Cattel, Impact of Event Scale - Revised by D. S. Weiss and C. R. Marmar. Women in remission showed most significant decrease in Financial position category and minor decrease in Work and Employment category and Friends, Acquaintances and Relatives category. Improvement of quality of life was recorded especially in category of Health, Sexuality, Own person, Partnership and in Relationship with own children and there was also a significant improvement to overall life satisfaction. Among healthy patients, there was a significant improvement in category of Health and Own person. Most significant decrease was in dimension of Financial position and Work and employment. Prophylactic mastectomy with reconstruction might be the way of prevention of breast carcinoma because from psychological point of view there is the unambiguously significant fact that there was improvement of perception of own health and own person in both groups of women. These are the quality of life aspects that are considered to be basal and long term stabilizing from the perspective of dynamics of own self and they also systematically influence

    Prophylactic treatment is mainly intended to reduce the frequency of migraine attacks. It is usually proposed to patients who suffer from two or more attacks per month. It should also be considered in patients who suffer from less frequent, but prolonged, disabling attacks with a poor response to abortive treatment, and who consider that their quality of life is reduced between attacks. Excessive intake of acute medication, more than twice a week, is a strong indication for prophylactic treatment. In order to obtain a good compliance to treatment, the patient must be informed of the expected efficacy of the drugs, and of their most frequent side effects. Thus, the choice of a prophylactic drug is made together with the patient. Based on the results of published controlled trials, the main prophylactic drugs are some betablockers, methysergide, pizotifene, oxetorone, flunarizine, amitriptyline, NSAIDs, and sodium valproate. Some less evaluated drugs such as aspirin, DHE, indoramine, verapamil, may be useful. Other substances such as riboflavin and new antiepileptic dugs are being evaluated. The choice of the drug to start with depends on several considerations. The first step is to make sure that there are no contra indications, and no possible interaction with the abortive medications. Then, possible side effects will be taken into account, for example, weight gain is a problem for most young women and patients who practice sports may not tolerate betablockers. Associated pathologies have to be checked. For example, a hypertensive migraine sufferers may benefit from betablockers; in a patient who suffers both from migraine and tension type headaches or from depression, amitriptyline is the first choice drug. The type of migraine should also be considered; for instance, in frequent attacks with aura, aspirin is recommended and betablockers avoided. In most cases, prophylaxis should be given as monotherapy, and it is often necessary to try successively several drugs

    The fruits of Grewia asiatica were evaluated for the antiemetic activity in the experimental model dogs, whereas, acute oral toxicity test was carried out in mice and rats. Maximum oral dose of 200 mg/kg and 600 mg/kg of crude alcoholic extract was found non toxic in mice and rats. Oral dose of crude alcoholic extract (120 mg/kg body weight) caused antiemetic effect in dogs in 3 h and controlled emesis centrally induced by Apomorphine (0.044 mg/kg body weight). This activity of G asiatica was comparable with standard commercial anti-emctic drugs like Maxolon (Metoclopramide) and Largactil tablets 10 mg (Chlorpromazine) of M/s. Aventis Pharma., Pakistan.

    The objective of this study was to develop an oral transmucosal formulation of an antiemetic drug that can not only serve in the active form but also provide a controlled release profile. In this study, sublingual films based on the biodegradable and water-soluble polymers, that is HPMCK-4M and PVPK-30, were developed by the solvent casting method, and were loaded with the antiemetic drug granisetron hydrochloride (granisetron HCl). The entrapment efficiency of the developed formulation was found to be 86%. The in vitro profile showed an instant release of the drug from the sublingual film, in a pattern following the first order kinetics array. The in vivo studies showed that granisetron HCl was delivered in its active state and showed effective results, as compared to its activity in the marketed formulation.

    Full Text Available Abstract Background Intermittent preventive treatment in infants (IPTi with sulphadoxine-pyrimethamine (SP reduces the incidence of malaria episodes in young children. The exact mechanism by which the protective effect is mediated needs to be defined. This study aimed to investigate therapeutic, prophylactic, and possible exceeding effects of SP-based IPTi in two clinical trials. Methods Protective efficacies from two IPTi trials performed in Kumasi, Ghana, and Lambaréné, Gabon, were assessed for overlapping time series of 61 days. For six-months periods after each of three IPTi doses a multivariate Poisson regression model with the respective cohort as co-variate was generated and effect modification of protective efficacy with time strata was evaluated by log-likelihood tests. Results Protective efficacies were not significantly different between the two study cohorts. Study-cohort corrected protective efficacy was highest for the first 61 days after each IPTi application and decreased continuously. For the first 61 days after IPTi-1, IPTi-2, and IPTi-3 the protective efficacy was 71%, 44%, and 43%, respectively. A reduction of the malaria incidence rate was detectable for the first 60, 30 and 40 days after IPTi-1, IPTi-2 and IPTi-3 drug application, respectively. After IPTi-3 a higher risk for malaria could be seen after day 60. This effect was mainly based on the overwhelming influence of the Kumasi cohort. Conclusion The results suggest that SP-based IPTi mainly works through a therapeutic and prophylactic effect over 30 to 60 days after drug application and that a sustained effect beyond post-treatment prophylaxis might be very low.

    Postoperative analgesia and antiemetic efficacy after intrathecal neostigmine were investigated in a randomized, double-blind, placebo-controlled trial of 100 patients undergoing abdominal hysterectomy. The patients were assigned to one of five groups (n = 20), and received intravenous prior to the spinal block the antiemetic test drug (except propofol) and 0.05 mg/kg midazolam. The control group (group C), the neostigmine group (group N), and the propofol group (group P) received saline as the test drug. The droperidol group (group D) received 0.5 mg intravenous droperidol, and the metoclopramide group (group M) 10 mg intravenous metoclopramide. Group P was single-blinded and had an intravenous continuous propofol infusion (2-4 mg/kg/h) turned on 10 minutes after the spinal injection. The intrathecal drugs administered were 20 mg hyperbaric bupivacaine (0.5%) associated with either 100 microg neostigmine or saline (for group C). Nausea, emetic episodes, and the need for rescue medication were recorded for the first 24 hours postoperative and scored by the Visual Analog Scale (VAS). Time-to-first-rescue medication and rescue medications in 24 hours were similar among the groups (P = .2917 and P = .8780, respectively). Intrathecal 100 microg neostigmine was associated with a high incidence of nausea and vomiting perioperative, leading to a high consumption of antiemetics (P antiemetic test drugs were effective in preventing nausea and vomiting after 100 microg neostigmine. Intrathecal neostigmine (100 microg) was ineffective for postoperative analgesia after abdominal hysterectomy due to side effects of nausea and vomiting.

    PURPOSE: To study the effect of prophylactic application of mitomycin-C on regression and corneal haze formation after photorefractive keratectomy (PRK for high myopia. METHODS: Fifty-four eyes of 28 high myopic patients were enrolled in this prospective study. All eyes underwent PRK with application of 0.02% mitomycin-C for two minutes and irrigation with 15-20 ml of normal saline. Follow-up visits were scheduled for the first 7 days and 1, 3 and 6 months after surgery. Hanna grading (in the scale of 0 to 4+ was used to assess corneal haze. RESULTS: Mean spherical equivalent refraction (SE was -7.08 ± 1.11 diopters (D, preoperatively. All eyes were examined on the first 7 days and one month after surgery; 48 eyes (88.9% were evaluated 3 and 6 months post-surgery. Six months after surgery, all eyes had uncorrected visual acuity (UCVA of 20/40 or better and 37 eyes (77.1 % achieved UCVA of 20/20 or better, 45 eyes (93.7% had SE within ±1.00D of emmetropia. One month postoperatively, 2 eyes (3.7% had grade 0.5 haze, while at 3 and 6 months after surgery no visited eye had haze at all. There was no decrease in best corrected visual acuity after 6 months. In spatial frequencies of 6 and 12 cycle/degree, contrast sensitivity decreased immediately after PRK but increased to the preoperative values by the 6th postoperative month

    Radiation-induced leukopenia was analyzed and assessed in breast cancer patients receiving prophylactic irradiation after radical mastectomy. Average white blood cell counts decreased to about 67 percent of the initial value after irradiation, and the ratio of the decrease was greater when the initial value was higher. During the course of the irradiation, white blood cell counts decreased to the lowest value by the middle of treatment time and stayed at the same level for one month after irradiation. The restorative or protective effects of taurine and cytochrome C were assessed by an open study, and that of DNA-spermidine by a double blind test, and the significant effects of each was observed.

    To determine the prophylactic effects of an elastin peptide derived from the bulbus arteriosus of bonitos and prolylglycine (PG), a degradation product of elastin peptide, on vascular dysfunction in spontaneously hypertensive rats (SHRs). Male 15-week-old SHR/Izm rats were fed without (control group) or with elastin peptide (1 g/kg body weight) for 5 weeks (EP group), or were infused via an osmotic mini-pump for 4 weeks with PG (PG group) or saline (control group). Using thoracic aortas, we assessed endothelial changes by scanning electron microscopy. Vascular reactivity (contraction and relaxation) and pressure-induced distension was compared. mRNA production levels of endothelial nitric oxide synthase (eNOS) and intercellular adhesion molecule-1 (ICAM-1) were investigated by real-time-polymerase chain reaction. Aortas of the EP group displayed limited endothelial damage compared with that in the control group. Under treatment of SHRs with elastin peptide, the effect of phenylephrine returned closer to the normal level observed in normotensive Wistar-Kyoto (WKY/Izm) rats. mRNA production of eNOS (but not ICAM-1) was greater in the EP group than in the control group. Endothelial damage was suppressed and pressure-induced vascular distension was greater in the PG group than in the corresponding control group. These results suggest that elastin peptide from bonitos elicits prophylactic affects hypertension-associated vascular dysfunction by targeting the eNOS signaling pathway. PG may be a key mediator of the beneficial effects of elastin peptide. Copyright © 2014 Elsevier Inc. All rights reserved.

    Herpes simplex virus type-2 (HSV2) infection increases HIV transmission. We explore the impact of a potential prophylactic HSV2 vaccination on HIV incidence in Africa using STDSIM an individual-based model. A campaign that achieved 70% coverage over 5 years with a vaccine that reduced susceptibility to HSV2 acquisition and HSV2 reactivation by 75% for 10 years, reduced HIV incidence by 30–40% after 20 years (range 4–66%). Over 20 years, in most scenarios fewer than 100 vaccinations were required to avert one HIV infection. HSV2 vaccines could have a substantial impact on HIV incidence. Intensified efforts are needed to develop an effective HSV2 vaccine. PMID:19071187

    Many medicinal plants have been employed during ages to treat urinary stones though the rationale behind their use is not well established. Thus, the present study was proposed to evaluate the effect of coconut water as a prophylactic agent in experimentally induced nephrolithiasis in a rat model. The male Wistar rats were divided randomly into three groups. Animals of group I (control) were fed standard rat diet. In group II, the animals were administrated 0.75% ethylene glycol in drinking water for the induction of nephrolithiasis. Group III animals were administrated coconut water in addition to ethylene glycol. All the treatments were continued for a total duration of seven weeks. Treatment with coconut water inhibited crystal deposition in renal tissue as well as reduced the number of crystals in urine. Furthermore, coconut water also protected against impaired renal function and development of oxidative stress in the kidneys. The results indicate that coconut water could be a potential candidate for phytotherapy against urolithiasis.

    Full Text Available Aim: Although prophylactic antibiotic treatment is still debatable, it is currently in use in recurrent urinary tract infections (UTIs. In the present study, we aimed to observe if prophylactic antibiotic use had any effect on the development of antibiotic resistance in patients with recurrent UTIs who we followed up in our clinic. Methods: The present study was performed on patients aged between one month and 16 years, who had recurrent UTIs, and were followed up by the Department of Pediatrics at Bülent Ecevit University Medical School. Patient files were retrospectively reviewed, and 50 patients who received antibiotic prophylaxis and 100 patients without prophylaxis were enrolled in the study. Urinary tests, subsequent urinary culture results, and antibiotic resistances were compared between the groups. Results: The mean age was 42.7±44.2 months. The most frequently cultured isolated bacterium was Escherichia coli (E. coli (58.4%. No difference was determined in bacteria in cultures between prophylaxis receivers and non-receivers. Isolation rate of E. coli was higher in urinary cultures in females than in males (p<0.001. When antibiotic resistance of all urinary culture-isolated bacteria was compared between the two groups, there was no statistically significant difference. However, an increased resistance against amoxicillin/clavulanic acid, ceftriaxone, and piperacillin was determined in prophylaxis group in whom E. coli was grown. In this study, general antibiotic resistance was most frequently observed against ampicillin (71.9%. Conclusion: In the present study, we observed that prophylaxis did not contribute so much to resistance other than E. coli. We recommend not preferring antibiotics which have increased resistance in our institution especially in children receiving prophylaxis for empirical treatment.

    Purpose: Prophylactic cranial irradiation (PCI) for the prevention of brain metastasis in small cell lung cancer remains controversial, both in terms of efficacy and the optimal dose-fractionation scheme. We performed this study to evaluate the efficacy of PCI at low doses. Methods and Materials: One hundred and ninety-seven patients were referred to our institution for treatment of limited stage small cell carcinoma of the lung between June 1986 and December 1992. Follow-up ranged from 1.1 to 89.8 months, with a mean of 19 months. Eighty-five patients received PCI. Results: Patients receiving PCI exhibited brain failure in 15%, while 38% of untreated patients developed metastases. This degree of prophylaxis was achieved with a median total dose of 25.20 Gy and a median fraction size of 1.80 Gy. At these doses, acute and late complications were minimal. Patients receiving PCI had significantly better 1-year and 2-year overall survivals (68% and 46% vs. 33% and 13%). However, patients with a complete response (CR) to chemotherapy and better Karnofsky performance status (KPS) were overrepresented in the PCI group. In an attempt to compare similar patients in both groups (PCI vs. no PCI), only patients with KPS ≥ 80, CR or near-CR to chemotherapy, and treatment with attempt to cure, were compared. In this good prognostic group, survival was still better in the PCI group (p = 0.0018). Conclusion: In this patient population, relatively low doses of PCI have accomplished a significant reduction in the incidence of brain metastasis with little toxicity. Whether such treatment truly improves survival awaits the results of additional prospective randomized trials

    Chemotherapy Induced Nausea and Vomiting (CINV) is a serious health concern in the treatment of cancer patients. Conventional routes for administering anti-emetics (i.e. oral and parenteral) have several drawbacks such as painful injections, poor patient compliance, dependence on skilled personnel, non-affordability to majority of population (parenteral), lack of programmability and suboptimal bioavailability (oral). Hence, we have developed a trans-epidermal antiemetic drug delivery patch using out-of-plane hollow silicon microneedle array. Microneedles are pointed micron-scale structures that pierce the epidermal layer of skin to reach dermal blood vessels and can directly release the drug in their vicinity. They are painless by virtue of avoiding significant contact with dermal sensory nerve endings. This alternate approach gives same pharmacodynamic effects as par- enteral route at a sparse drug-dose requirement, hence negligible side-effects and improved patient compliance. Microneedle design attributes were derived by systematic study of human skin anatomy, natural micron-size structures like wasp-sting and cactus-spine and multi-physics simulations. We used deep reactive ion etching with Bosch process and optimized recipe of gases to fabricate high-aspect-ratio hollow silicon microneedle array. Finally, microneedle array and polydimethylsiloxane drug reservoir were assembled to make finished anti-emetic patch. We assessed microneedles mechanical stability, physico-chemical properties and performed in-vitro, ex- vivo and in-vivo studies. These studies established functional efficacy of the device in trans-epidermal delivery of anti-emetics, its programmability, ease of use and biosafety. Thus, out-of-plane hollow silicon microneedle array trans-epidermal antiemetic patch is a promising strategy for painless and effective management of CINV at low cost in mainstream healthcare.

    Aspirin and nonsteroidal anti-inflammatory agents are known to induce gastroduodenal complications such as ulcer, bleeding, and dyspepsia. In this study, we examined the prophylactic effect of rebamipide, an anti-ulcer agent with free-radical scavenging and anti-inflammatory effect, on acidified aspirin-induced gastric mucosal injury in rats. In addition, we investigated the mucosal barrier functions disrupted by aspirin. Oral administration of acidified aspirin resulted in linear hemorrhagic erosions with increasing myeloperoxidase activity and thiobarbituric acid-reactive substance concentrations in the gastric mucosa. Rebamipide suppressed these acidified aspirin-induced gastric lesions and inflammatory changes significantly, and its protective effect was more potent in the case of repeated (twice daily for 3 days) treatment than single treatment before aspirin administration. Immunostaining of zonula occludens (ZO)-1, one of the tight junctional proteins, was strengthened in rat gastric mucosa after repeated administration of rebamipide. In addition, aspirin induced the increasing transport of fluorescine isothiocyanate-labeled dextrans with localized disruption and decreased expression of ZO-1 protein on rat gastric mucosal cell line RGM-1. Rebamipide effectively prevented aspirin-induced permeability changes and disruption of ZO-1 distribution. These results suggest that rebamipide protects against aspirin-induced gastric mucosal lesions by preserving gastric epithelial cell-to cell integrity in addition to the anti-inflammatory effects.

    The purpose of this study was to examine the effectiveness and value of prophylactic 5-layer foam sacral dressings to prevent hospital-acquired pressure injury rates in acute care settings. Retrospective observational cohort. We reviewed records of adult patients 18 years or older who were hospitalized at least 5 days across 38 acute care hospitals of the University Health System Consortium (UHC) and had a pressure injury as identified by Patient Safety Indicator #3 (PSI-03). All facilities are located in the United States. We collected longitudinal data pertaining to prophylactic 5-layer foam sacral dressings purchased by hospital-quarter for 38 academic medical centers between 2010 and 2015. Longitudinal data on acute care, hospital-level patient outcomes (eg, admissions and PSI-03 and pressure injury rate) were queried through the UHC clinical database/resource manager from the Johns Hopkins Medicine portal. Data on volumes of dressings purchased per UHC hospital were merged with UHC data. Mixed-effects negative binomial regression was used to test the longitudinal association of prophylactic foam sacral dressings on pressure injury rates, adjusted for hospital case-mix and Medicare payments rules. Significant pressure injury rate reductions in US acute care hospitals between 2010 and 2015 were associated with the adoption of prophylactic 5-layer foam sacral dressings within a prevention protocol (-1.0 cases/quarter; P = .002) and changes to Medicare payment rules in 2014 (-1.13 cases/quarter; P = .035). Prophylactic 5-layer foam sacral dressings are an effective component of a pressure injury prevention protocol. Hospitals adopting these technologies should expect good value for use of these products.

    Mucuna pruriens is widely used in traditional medicine for treatments of various diseases. In certain region of Nigeria, the seed is used as oral prophylactics for snakebite. Rats pretreated with the aqueous extract from M. pruriens seed (MPE) were protected against the lethal effects of Naja sputatrix (Javan spitting cobra) venom [Tan et al., J Ethnopharmacol, 123 (2009) 356]. The pretreatment also protected against venom-induced histopathological changes in rat heart. To contribute to the understanding of the mechanism of cardio-protective action, the present study examined the effects of MPE-pretreatment on gene expression profile of rat heart as well as effect of MPE-pretreatment on N. sputatrix venom-induced gene expression alterations in rat heart. The gene expression profiles were examined by microarray analysis and verified by real time PCR. The results showed that pretreatment with MPE caused 50 genes in the rat heart substantially up-regulated of which 19 were related to immune responses, 7 were related to energy production and metabolism. The up-regulation of genes related to energy metabolism probably plays a role in maintaining the viability of the heart. Four other genes that were up-regulated (alpha synuclein, natriuretic peptide precursor, calsequestrin and triadin) were involved in the maintenance of homeostasis of the heart or maintaining its viability, thereby contributing to the direct protective action. The results demonstrated that protective effect of MPE pretreatment against snake venom poisoning may involve a direct action on the heart.

    To study the prophylactic effects of four Chinese traditional prescriptions against experimental liver injury. Liver toxins, alpha-naphthylisothiocyanate (ANIT), and carbon tetrachloride (CCl4) were used to induce acute liver injury. Simo Yin(SMY), Guizhi Fuling Wan (GFW), Xieqing Wan (XQW), and Sini San (SNS) were fed (500 mg/kg, in saline, po) to the rats before toxin administration. All the animals were killed 48 h after toxin insulted. Serum index of liver function and hepatic lipid peroxidation (LPO) were estimated. Histopathological observation was conducted simultaneously. The rats treated with ANIT exhibited elevations of serum total bilirubin (TBI), alkaline phosphatase (ALP), glutamate-oxalate- transaminase (GOT), glutamate-pyruvate-transaminase (GPT), as well as cholestasis and parenchyma necrosis. In rats, challenged with ANIT, receiving the pre-treatment of prescriptions of SMY, XQW, and SNS, the biochemical and morphological parameters of liver injury were significantly reduced. The increased LPO level in liver tissue, associated with the provoked serum GOT and GPT levels were the salient features observed in CCl4-insulting rats. Pre-treatment of four prescriptions showed a remarkable protective effect, and also was effective in counteracting the free radical toxicity by bringing about a significant decrease in peroxidative level. These recipes ameliorate liver damage induced by both ANIT and CCl4 despite the differences in their mechanisms of injury. Therefore they may be able to exert hepatoprotective effects through more than one mechanism of action because they contained a mixture of anti-hepatotoxic ingredients with mutual reinforcement and assistance.

    The purpose of this retrospective study is to assess the frequency and intensity of chronic nausea in patients admitted to the Palliative Care Unit and the results of a metoclopramide-based treatment regimen. We reviewed the medical records of 100 consecutive patients admitted to the Palliative Care Unit at the Edmonton General Hospital until death during 1992-1993. All patients had terminal cancer and normal cognitive function. All patients completed the Functional Analogue Scale for appetite, nausea, pain, activity, shortness of breath, and sensation of well-being at 1000 and 1600 hours every day. Patients who complained of nausea initially received metoclopramide 10 mg every 4 hr orally or subcutaneously (Step 1). If nausea persisted, dexamethasone 10 mg twice daily was added (Step 2). Step 3 consisted of a continuous subcutaneous infusion of metoclopramide of 60-120 mg/day plus dexamethasone. If no response was observed, other antiemetics were administered (Step 4). Upon admission to the unit, 32 patients (32%) presented with nausea. During the average admission of 25 +/- 13 days, 98 patients (98%) developed nausea. Twenty-five patients (25%) required other antiemetics because of bowel obstruction (18), extrapyramidal side effects (3), or other reasons (4). Most patients without bowel obstruction achieved excellent control of nausea using the metoclopramide-based regimen. During the first 5 days and last 5 days of admission, nausea had significantly lower intensity than the rest of the symptoms that were monitored. Our results suggest that, although nausea is very frequent, it can be well controlled in the majority of patients using safe and simple antiemetic regimens.

    Full Text Available Introduction: One of the common problems in neonatal period is jaundice that occurs in the first week of birth in 60% of term and 80% of preterm neonates. In preterm newborn hyperbilirubinaemia is higher, persistent, longer, and more likely to be associated with neurological injury than term neonates. The purpose of this study was to determine Prophylactic effect of zinc sulphate on hyperbilirubinemia in premature very low birth weight neonates. Method and Material: Sixty Newborns who admitted in our NICU which had inclusion criteria were eligible in this trial. Included neonates were randomly placed in two groups (case and control and before intervention the total serum bilirubin (TSB was measured at second day. The participant received either 20 mg of zinc sulfate or placebo through NG-tube divided in two doses till day seven of age. Then total and indirect bilirubin was measured at 3ed, 5th and 7th day of life. If any of newborns in duration of hospitalization develop clinical jaundice, after assessment of bilirubin, need for phototherapy was evaluated based on phototherapy and exchange schedule as described by the American Academy of Pediatrics guidelines. The termination point of phototherapy was defined as a bilirubin level less than 50 percent of starting point. After gathering Data, they were analyzed using SPSS software (version 11.5 and T-test, Chi-square and repeated measurement tests. Results: Seventy eight patients enrolled in this trial that 18 cases were excluded and the remaining cases divided into two equal groups (N=30 in each group. Demographic condition was similar in two groups. There were no different between two groups in decreasing total serum bilirubin and duration of phototherapy. Conclusion: This study showed that zinc sulfate has no preventing effective in hyperbilirubinemia in preterm very low birth weight neonates. It has also no effect on duration of phototherapy.

    Márcio Cavalcante Salmito

    Full Text Available Abstract Introduction: Vestibular migraine (VM is now accepted as a common cause of episodic vertigo. Treatment of VM involves two situations: the vestibular symptom attacks and the period between attacks. For the latter, some prophylaxis methods can be used. The current recommendation is to use the same prophylactic drugs used for migraines, including β-blockers, antidepressants and anticonvulsants. The recent diagnostic definition of vestibular migraine makes the number of studies on its treatment scarce. Objective: To evaluate the efficacy of prophylactic treatment used in patients from a VM outpatient clinic. Methods: Review of medical records from patients with VM according to the criteria of the Bárány Society/International Headache Society of 2012 criteria. The drugs used in the treatment and treatment response obtained through the visual analog scale (VAS for dizziness and headache were assessed. The pre and post-treatment VAS scores were compared (the improvement was evaluated together and individually, per drug used. Associations with clinical subgroups of patients were also assessed. Results: Of the 88 assessed records, 47 were eligible. We included patients that met the diagnostic criteria for VM and excluded those whose medical records were illegible and those of patients with other disorders causing dizziness and/or headache that did not meet the 2012 criteria for VM. 80.9% of the patients showed improvement with prophylaxis (p < 0.001. Amitriptyline, Flunarizine, Propranolol and Topiramate improved vestibular symptoms (p < 0.001 and headache (p < 0.015. The four drugs were effective in a statistically significant manner. There was a positive statistical association between the time of vestibular symptoms and clinical improvement. There was no additional benefit in hypertensive patients who used antihypertensive drugs as prophylaxis or depressed patients who used antidepressants in relation to other prophylactic drugs. Drug

    The incidence of cervical cancer (CC) is high in Japan and is further increasing among women younger than 30 years. This burden could be reduced by the implementation of a CC vaccine, but its cost-effectiveness is unknown. We quantified the clinical impact and assessed the cost-effectiveness of adding CC vaccination at age 12 to the current screening in place in Japan with a lifetime Markov model adapted to the Japanese setting. Transition probabilities and utility values were obtained from public databases. Direct costs for treatment and screening were estimated using Japanese medical fees. Annual costs and benefits were discounted at 3%. Sensitivity analyses were conducted on the age at vaccination, the vaccine characteristics, the discount rates, the proportion of human papillomavirus types 16/18 in cancer, and the screening coverage. Vaccinating a 12-year-old cohort was predicted to reduce CC incidence and deaths from CC by 73%. These clinical effects were associated with an incremental cost-effectiveness ratio of yen1.8 million per quality-adjusted life year gained. The incremental cost-effectiveness ratio of vaccinating all 10- to 45-year-old women was yen2.8 million per quality-adjusted life year, still below the threshold value. The implementation of a CC vaccination in Japan could reduce the CC burden in a very cost-effective manner for women up to 45 years.

    To make comparisons between acupuncture and acupressure for preventing menstrual migraine (MM). MM is one kind of migraine associated with females' menses. It is often associated with increased menstrual distress and disability, leading to decreased daily activity and quality of life. A randomized and controlled pilot study with three groups: verum acupuncture (VA) group, acupressure (AP) group, and control acupuncture (CA) group. The study lasted for seven cycle-months, with a 1-cycle-month baseline observation (T1), a 3-cycle-month intervention (three times per cycle-month) (T2-T4), and a 3-cycle-month follow-up (T5-T7). Outcome measures were number of migraine days, average and peak pain, total duration period of MM, and percentage of patients with ≥ 50% reduction in the number of MM days. A total of 18 participants were included in the analysis (VA, n = 7; AP, n = 6; CA, n = 5). Both VA and AP were significantly more effective than CA for reducing MM days during the intervention period. Both VA and AP tended to be more effective than CA for reducing peak pain during the intervention period. No significant differences for the outcomes were observed among VA, AP, and CA during the follow-up period. No serious adverse events were reported. Results of the pilot study suggest that both VA and AP could be considered as alternative and safe prophylactic interventions for MM. Register ClinicalTrials.gov Identifier: NCT02592681.

    Postoperative nausea and vomiting (PONV) remains the most common postoperative complication, and causes decreased patient satisfaction, prolonged postoperative hospital stays, and unanticipated admission. There are limited data that indicate that dextrose may reduce nausea and vomiting. In this trial, we attempted to determine whether the rate of PONV can be decreased by postoperative administration of IV dextrose bolus. To test the effect of postoperative dextrose administration on PONV rates, we conducted a double-blind, randomized, placebo-controlled trial. We enrolled 62 nondiabetic, ASA class I or II nonsmoking outpatients scheduled for gynecologic laparoscopic and hysteroscopic procedures. Patients were randomized into 2 groups: the treatment group received dextrose 5% in Ringer lactate solution, and the control (placebo) group received Ringer lactate solution given immediately after surgery. All patients underwent a standardized general anesthesia and received 1 dose of antiemetic a half hour before emergence from anesthesia. PONV scores, antiemetic rescue medications, narcotic consumption, and discharge time were recorded in the postanesthesia care unit (PACU) in half-hour intervals. The 2 groups were similar with regard to age, weight, anxiety scores, prior PONV, non per os status, presurgical glucose, anesthetic duration, intraoperative narcotic use, and total weight-based fluid volume received. Postoperative nausea scores were not significantly different in the dextrose group compared with the control group (P > 0.05) after Bonferroni correction for repeated measurements over time. However, patients who received dextrose 5% in Ringer lactate solution consumed less rescue antiemetic medications (ratio mean difference, 0.56; 95% confidence interval, 0.39-0.82; P = 0.02), and had a shorter length of stay in the PACU (ratio mean difference, 0.80; 95% confidence interval, 0.66-0.97; P = 0.03) compared with patients in the control group.

    Nausea and vomiting (NV) are the most prevalent adverse effects of chemotherapy (CT). This study was conducted to evaluate adherence of the health care team to standard guidelines for antiemetics usage to prevent acute chemotherapy-induced nausea and vomiting (CINV) in a large CT center. A prospective study was performed during an 11-month period on patients receiving CT. A form was designed to collect patients' demographic information and their chemotherapeutic and antiemetic regimen data. The Likert scale was used to measure the effectiveness of the antiemetics in patients. In this study, the effect of patient-related risk factors on the incidence rate of CINV was examined. Based on the results, CINV events were reported by 74.4% of patients. The antiemetic regimen of 71.2% of the patients complied with the guidelines. The complete response, complete protection, and complete control end points did not differ significantly between patients undergoing guidelines-consistent prophylaxis or guidelines-inconsistent prophylaxis. The females clearly showed a higher incidence rate of CINV ( P =0.001) during the first course of CT ( P =0.006). A history of motion sickness did not affect the incidence of NV. The maximum compliance error occurred for the use of aprepitant, as 16.16% of the patients who were receiving aprepitant did not comply with its instructions. The results of this study highlight how CINV was controlled in this center, which was significantly lower than that of the global standard. Perhaps, factors such as noncompliance to antiemetic regimens with standard guidelines and the failure to adhere to the administration instructions of the antiemetics were involved in the incomplete control of CINV.

    At cancer treatment, the use of antiemetics are often needed due to induction of nausea and vomiting. Some antiemetics have been shown to interact with the direct cytotoxic effects. The newly developed antiemetics have, so far as we know, not been studied in this respect. In the present study, the effects of the 5-HT{sub 3} receptor antagonists ondansetron and granisetron were evaluated on the cytotoxicity, induced by irradiation, bleomycin, epirubicin, estramustine, and cisplatin using fibroblasts (V79) and lung cancer cells (P31) in vitro. Ondansetron or granisetron (10{sup -5} mol/l) had no effect on the survival of irradiated cells. Granisetron (10{sup -5} mol/l) significantly potentiated cytoxocity of 2.5 mg/l epirubicin on fibroblasts whereas the effect of granisetron (10{sup -7} mol/l) on the cytotoxic effect of 25 mg/l bleomycin, and estramustine (80 mg/l) seemed additive to lung cancer cells. Ondansetron was non-interactive with the cytotoxicity induced by any of the anti-cancer drugs. Although the encountered observation with an enhancing effect of granisetron on the epirubicin-induced cytotoxicity is seen in a specific experimental situation in vitro, the fact that 5-HT{sub 3} receptor antagonists are routinely used during cancer treatment indicate that attention should be given to a possible interaction with the antineoplastic action of cancer treatment.

    Amaro Afrânio de Araújo-Filho

    Full Text Available OBJECTIVE: During cardiac surgery, several factors contribute to the development of postoperative pulmonary complications. Non-invasive ventilation is a promising therapeutic tool for improving the functionality of this type of patient. The aim of this study is to evaluate the functional capacity and length of stay of patients in a nosocomial intensive care unit who underwent prophylactic non-invasive ventilation after heart valve replacement. METHOD: The study was a controlled clinical trial, comprising 50 individuals of both sexes who were allocated by randomization into two groups with 25 patients in each group: the control group and experimental group. After surgery, the patients were transferred to the intensive care unit and then participated in standard physical therapy, which was provided to the experimental group after 3 applications of non-invasive ventilation within the first 26 hours after extubation. For non-invasive ventilation, the positive pressure was 10 cm H2O, with a duration of 1 hour. The evaluation was performed on the 7th postoperative day/discharge and included a 6-minute walk test. The intensive care unit and hospitalization times were monitored in both groups. Brazilian Registry of Clinical Trials (REBeC: RBR number 8bxdd3. RESULTS: Analysis of the 6-minute walk test showed that the control group walked an average distance of 264.34±76 meters and the experimental group walked an average distance of 334.07±71 meters (p=0.002. The intensive care unit and hospitalization times did not differ between the groups. CONCLUSION: Non-invasive ventilation as a therapeutic resource was effective toward improving functionality; however, non-invasive ventilation did not influence the intensive care unit or hospitalization times of the studied cardiac patients.

    Purpose: Radiotherapy induced dermatitis is a common and sometimes serious side effect. We conducted a randomized study to understand whether the adjunctive use of aloe vera gel might reduce the prevalence and/or severity of radiotherapy induced dermatitis. Methods: One hundred patients with newly diagnosed breast cancer were randomized to receive aloe vera gel or nothing during adjuvant radiotherapy consisting of conventional external beam radiation using 6 MV mega voltage linear accelerator photons. The radiation portals were composed of breast fields in all patients and supraclavicular and posterior axillary fields in node positive cases. The total dose was 50 Gy with a daily fraction of 2 Gy, five fractions per week. Results: Dermatitis was first found among patients of both groups after week 2. In the aloe vera and control groups, 2/8 patients and 5/12 patients had dermatitis grade 1 after weeks 2 (P value = 0.240) and 3 (P value = 0.317). After the 4th week, the numbers were 18 and, 23 fordermatitis grade 1 and only 1 for grade 3 dermatitis (P value = 0.328). After the 5th week, 31, 12 and 2 patients in the aloe vera group and 36, 6 and 5 of the controls had grades 1, 2 and 3 dermatitis, respectively (P value = 0.488).

    To determine the effect of prophylactic tranexamic acid (TA) on calculated and measured blood loss after vaginal delivery in women at low risk of postpartum haemorrhage. In this double-blind randomised controlled trial, 120 women with a singleton pregnancy were randomly allocated to receive either one gram intravenous TA or placebo in addition to 10 IU oxytocin after delivery of the fetus. Calculated blood loss was determined based on haematocrit before delivery and 12-24 h postdelivery. The quantity of blood loss was measured during two time periods: from delivery of the fetus to placental expulsion and from placental expulsion to the end of the second hour after childbirth. The mean (SD) calculated total blood loss (519 (320) vs 659 (402) mL, P = 0.036) and measured blood loss from placental delivery to 2 h postpartum (69 (39) vs 108 (53) mL, P  1000 mL was lower in the TA group (7% vs 18%, P = 0.048). Prophylactic TA reduces blood loss after vaginal delivery in women with a low risk of postpartum haemorrhage. The prophylactic use of TA may reduce blood loss complications and enhance maternal health. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Enterococcus lactis IW5 was obtained from human gut and the potential probiotic characteristics of this organism were then evaluated. Results showed that this strain was highly resistant to low pH and high bile salt and adhered strongly to Caco-2 human epithelial colorectal cell lines. The supernatant of E. lactis IW5 strongly inhibited the growth of several pathogenic bacteria and decreased the viability of different cancer cells, such as HeLa, AGS, HT-29, and MCF-7. Conversely, E. lactis IW5 did not inhibit the viability of normal FHs-74 cells. This strain did not generate toxic enzymes, including β-glucosidase, β-glucuronidase, and N-acetyl-β-glucosaminidase and was highly susceptible to ampicillin, gentamycin, penicillin, vancomycin, clindamycin, sulfamethoxazol, and chloramphenicol but resistant to erythromycin and tetracyclin. This study provided evidence for the effect of E. lactis IW5 on cancer cells. Therefore, E. lactis IW5, as a bioactive therapeutics, should be subjected to other relevant tests to verify the therapeutic suitability of this strain for clinical applications.

    Nausea and vomiting may occur in a significant minority of patients following hepatic artery embolization with yttrium-90 spheres (K. T. Sato et al. Radiology 247:507-515, 2008). This encumbers human and economic resources and undercuts the assertion that it is as a well-tolerated outpatient treatment. A single intravenous dose of palonosetron HCl was administered before hepatic artery embolization with yttrium-90 spheres to ameliorate posttreatment nausea and vomiting, in 23 consecutive patients. The patients were discharged the day of procedure on oral antiemetics, steroids, and blockers of gastric acid release. All patients had clinical and laboratory evaluation at 2 weeks after the procedure. The data were gathered and reviewed retrospectively. At 2-week follow-up, none reported significant nausea, vomiting, additional antiemetic use, need for parenteral therapy, hospital readmission, or palonosetron-related side effects. All patients recovered from postembolization symptoms within a week after treatment. In conclusion, this retrospective study suggests that single-dose palonosetron is feasible, safe, and effective for acute and delayed nausea and vomiting in this group of patients. The added cost may be offset by benefits.

Several antiemetic options exist to manage CINV. Corticosteroids, serotonin receptor antagonists, and neurokinin receptor antagonists are the classes most commonly used in the prevention of CINV. There are many alternative drug classes utilized for the prevention and management of CINV such as antihistamines, benzodiazepines, anticonvulsants, cannabinoids, and dopamine receptor antagonists. Medications belonging to these classes generally have lower efficacy and are associated with more adverse effects. They are also not as well studied compared to the aforementioned agents. This review will focus on dronabinol, a member of the cannabinoid class, and its role in CINV. Cannabis sativa L. (also known as marijuana contains naturally occurring delta-9-tetrahydrocannibinol (delta-9-THC. The synthetic version of delta-9-THC is the active ingredient in dronabinol that makes dronabinol an orally active cannabinoid. Evidence for clinical efficacy of dronabinol will be analyzed in this review as monotherapy, in combination with ondansetron, and in combination with prochlorperazine.

    1998-01-01

    A double-blind randomized crossover trial was performed to compare the antiemetic efficacy of two 5-HT3 receptor antagonists, granisetron and ondansetron, in Chinese patients receiving adjuvant chemotherapy (cyclophosphamide, methotrexate and 5-fluorouracil) for breast cancer. Twenty patients were randomized to receive chemotherapy with either granisetron on day 1 and ondansetron on day 8 of the first cycle followed by the reverse order in the second cycle, or vice versa. The number of vomiting episodes and the severity of nausea in the first 24 h (acute vomiting/nausea) and the following 7 days (delayed vomiting/nausea) were studied. Acute vomiting was completely prevented in 29 (72.5%) cycles with granisetron and 27 (67.5%) cycles with ondansetron, and treatment failure (>5 vomiting episodes) occurred in two (5%) cycles with each agent (P = NS). Acute nausea was completely controlled in 15 (37.5%) cycles with granisetron and 14 (35%) cycles with ondansetron, whereas severe acute nausea occurred in four (10%) cycles with each agent (P = NS). However, complete response for delayed vomiting was observed in only 21 (52.5%) cycles with granisetron and 22 (55%) cycles with ondansetron (P = NS), and delayed nausea was completely controlled in only 11 (27.5%) and ten (25%) cycles respectively (P = NS). In conclusion, both granisetron and ondansetron are effective in controlling acute nausea and vomiting in Chinese patients, with equivalent antiemetic efficacy. Control of delayed nausea and vomiting is less satisfactory. PMID:9635849

    Preliminary data on the effects of prophylactic bilateral salpingectomy (PBS) show that postoperative ovarian function is preserved up to 3 months after surgery. The confirmation of PBS safety on ovarian function even many years after surgery is essential to reassure the medical community that this new strategy, recently proposed for the prevention of ovarian cancer, is at least able to avoid the risk of premature surgical menopause. We investigated whether the addition of PBS during total laparoscopic hysterectomy (TLH) causes long-term effects on ovarian function. An observational study (Canadian Task Force classification II-3). Department of Obstetrics and Gynecology, "Magna Graecia" University, Catanzaro, Italy. Seventy-nine patients who underwent TLH plus salpingectomy between September 2010 and September 2012 at our institution have been recalled to be submitted to ovarian reserve evaluation in February 2015. Eight of 79 women refused to participate in this follow-up study. The ovarian age of PBS patients has been determined through OvAge (OvAge sr., Catanzaro, Italy), a statistical model that combines antimüllerian hormone, follicle-stimulating hormone, 3-dimensional antral follicle count, vascular index, flow index, and vascular flow index values. The control group consisted of a large population of 652 healthy women (with intact uterus and adnexa) previously enrolled to build the OvAge model. Comparisons between ovarian ages of PBS patients and the control group have been assessed by analysis of covariance linear statistical modeling. The main outcome measurement was the differences in the behavior within OvAge/age relation between PBS and control women. Descriptive statistics of those 71 enrolled PBS patients are the following: age, 49.61 ± 2.15 years; OvAge, 49.22 ± 2.57 years; follicle-stimulating hormone, 43.02 ± 19.92 mU/mL; antimüllerian hormone, 0.12 ± 0.20 ng/mL; 3-dimensional antral follicle count, 1.91 ± 1.28; vascular index

    The effects of prophylactic oral Ca supplementation on blood mineral status and markers of energy balance were evaluated on 205 multiparous Jersey cows at a commercial dairy. Postpartum, cows were systematically assigned to control (n = 105) or oral Ca supplementation (CaOS; 50 to 60 g of Ca as boluses; n = 100) at 0 and 1 d in milk (DIM). Blood samples for analysis of serum minerals (Ca, P, Mg, K, Na, Fe, Zn, and Cu) were collected before and 1 h after treatment at 0 and 1 DIM, and at 2 DIM. Urine pH was measured immediately before and 1 h after treatment administration (n = 96). A subset of 74 cows was evaluated for plasma glucose and fatty acid concentrations at 0, 1, and 2 DIM. Cows were classified according to their initial calcemic status (Ca status) as normocalcemic (NC; serum Ca >2.12 mmol/L) or subclinically hypocalcemic (SCH; serum Ca ≤2.12 mmol/L). Average serum Ca concentration was higher in CaOS than control cows (2.12 vs. 2.06 mmol/L); this treatment effect was higher for SCH [CaOS (2.03 mmol/L); control (1.89 mmol/L)] than NC cows [CaOS (2.22 mmol/L); control (2.22 mmol/L)]. The incidence of subclinical hypocalcemia was lower for CaOS than control cows (53 vs. 65%); however, at 2 DIM the prevalence of subclinical hypocalcemia tended to be higher for CaOS cows, mostly because it was higher for CaOS-NC than control-NC cows (70 vs. 25%). Urine pH was lower for CaOS than control cows (6.10 vs. 7.04). Lower serum Mg concentration was detected for CaOS-SCH (1.06 mmol/L) than for control-SCH (1.10 mmol/L) cows. Cows in the CaOS group had higher serum K (4.68 vs. 4.53 mmol/L), lower plasma glucose (2.97 vs. 3.10 mmol/L), and at 2 DIM higher plasma fatty acid concentrations (0.43 vs. 0.35 mmol/L) than control cows. Our results showed that postpartum serum Ca concentration increases with oral Ca supplementation, but calcemic status influenced treatment response. Future studies should evaluate the long-term implications on production and reproduction of oral

    Cytokines are known to increase in the patients subjected to open chest surgery. Those patients are usually administered with antibiotic agents for prophylaxis, while some of antibiotic agents might yield significantly higher level of cytokines than other agents especially in patients suffering from severe infections. It is believed that imipenem may yield lower interleukin-6 (IL6) level than cephem antibiotics. To study whether such difference could be observed in the patients who show no sign of severe infections, a total of 13 patients underwent scheduled open chest surgery were allocated at random into two groups, the imipenem-group and the flomoxef-group. The cytokine levels of the patients in the two groups were compared, while the prophylactic administration of imipenem or flomoxef. In both groups, IL6 increased immediately after the operation while endotoxin remained unchanged. Thereafter IL6 decreased gradually in both groups, however, the decrease of IL6 in the imipenem-group was faster and greater than the flomoxef-group resulting in the significantly lower level of IL6 on the 4th day after operation. One week after the operation, there existed no difference in the IL6 levels between these two groups. In conclusion, it was suggested that, depending on the choice of a prophylactic antibiotic agent, some invasive burden could be added to those patients underwent open chest surgery, a certain number of whom would develop severe infection.

    The prophylactic administration of antibiotics to prevent infection and the prophylactic administration of anticonvulsants to prevent first seizure episodes are common practice in neurosurgery. If prophylactic medication therapy is not indicated, the patient not only incurs the discomfort and the inconvenience resulting from drug treatment but is also unnecessarily exposed to adverse drug reactions, and incurs extra costs. The main situations in which prophylactic anticonvulsants and antibiotics are used are described and those situations we found controversial in the literature and lack further investigation are identified: anticonvulsants for preventing seizures in patients with chronic subdural hematomas, antiepileptic drugs for preventing seizures in those suffering from brain tumors, antibiotic prophylaxis for preventing meningitis in patients with basilar skull fractures, and antibiotic prophylaxis for the surgical introduction of intracranial ventricular shunts.In the following we present systematic reviews of the literature in accordance with the standard protocol of The Cochrane Collaboration to evaluate the effectiveness of the use of these prophylactic medications in the situations mentioned. Our goal was to efficiently integrate valid information and provide a basis for rational decision-making.

    Full Text Available Abstract Background: Most of the current regimens in the treatment of multiple myeloma include thalidomide. Thalidomide is a modulator of the immune system and according to several studies, its main complication is thromboembolism. The aim of this study is to compare the thromboemboli prophylactic effect of aspirin and low dose warfarin in standard risk multiple myeloma patients that treated with regimens containing thalidomide. Materials and Methods: In this double- blind clinical trial study, sixty-six patients with multiple myeloma under treatment with thalidomide-containing regimens with standard risk for thromboembolism who were admitted to Khansari hospital, entered the study according to inclusion and exclusion criteria. The incidence of thromboembolism in these patients was evaluated. Results: Five patients in the warfarin group and 2 patients in the aspirin group had thromboemboli. Chi square analyses showed no significant difference between groups (p=0.635. Conclusion: The results showed that both drugs are effective in preventing thromboembolism and can be used as a prophylactic treatment.

    Medtep Hemophilia platform is an online tool that allows patients with congenital coagulopathies to keep track of their daily condition-related events with the objective of ensuring successful adherence to therapy. To assess the effectiveness of Medtep Hemophilia in improving adherence to prophylactic treatment in haemophilia A and B patients in a 1-year prospective observational study, as well as its impact on the patient's disease status. Patients (>13 years old) received support material to familiarize themselves with Medtep Hemophilia. Adherence to treatment, quality of life (QoL) and illness perception were assessed. Values at baseline, 1, 6 and 12 months, and changes from baseline value were analysed. The Hemophilia Joint Health Score (HJHS) test was applied at baseline and study completion. Forty-six patients were enrolled (43 evaluable). After 1 year, 56.4% patients showed continued use of the platform (100% compliance) whereas 25.6% were inactive. Treatment adherence increased both significantly (P 80% of platform use) tended to score better than noncompliant. The HJHS test values remained similar during the study. The Medtep Hemophilia online platform helped the studied patients with haemophilia to improve their adherence to prophylactic treatment, while increasing their QoL and illness perception, as well as joint arthropathies stabilization. © 2018 John Wiley & Sons Ltd.

    Multiple myeloma (MM) patients have a propensity for thromboembolic events (TE), and treatment with thalidomide/dexamethasone or lenalidomide/dexamethasone increases this risk. This report describes the use of low-dose aspirin (81 mg) as primary thromboprophylaxis in three series of MM patients receiving thalidomide or lenalidomide with other drugs. In the first regimen (clarithromycin, thalidomide, dexamethasone), initiation of low-dose aspirin negated the occurrence of any further TE. In a second study, prophylactic aspirin given with thalidomide/dexamethasone resulted in a rate of TE similar to that seen with dexamethasone alone (without aspirin). A third study (n = 72) evaluated thrombosis rates with aspirin and a lenalidomide-containing regimen (clarithromycin, lenalidomide, dexamethasone). Of nine occurrences of thromboembolism, five were associated with aspirin interruption or poor compliance. Low-dose aspirin appears to reduce the incidence of thrombosis with these regimens. Routine use of aspirin as antithrombotic prophylaxis in MM patients receiving immunomodulatory drugs with corticosteroids is warranted.

    Natale, James J

    2015-01-01

    This review provides background information on chemotherapy-induced nausea and vomiting (CINV) classification and pathophysiology and reviews various antiemetic agents for CINV prophylaxis, including corticosteroids, serotonin receptor antagonists (5-HT3 RAs), tachykinin NK1 receptor antagonists (NK1 RAs), and olanzapine. Other less commonly used agents are briefly discussed. Practical considerations are reviewed as well, including emetogenicity of chemotherapeutic regimens, patient-specific risk factors for CINV, principles of CINV management, health economics outcome research, and quality of life. Available data on the newly FDA-approved antiemetic combination netupitant/palonosetron (NEPA) is also reviewed. Prevention of CINV is an important goal in managing patients with cancer and is especially difficult with respect to nausea and delayed CINV. Corticosteroids are a mainstay of CINV prophylaxis and are usually given in combination with other therapies. The 5-HT3 RA palonosetron has shown increased efficacy over other agents in the same class for prevention of delayed emesis with moderately emetogenic chemotherapy and NK1 RAs improve emesis prevention in combination with 5-HT3 RAs and dexamethasone. Olanzapine has shown efficacy for CINV prophylaxis and the treatment of breakthrough CINV. The new combination therapy, NEPA, has been shown to be efficacious for the prevention of acute, delayed, and overall CINV. Risk factors that have been identified for CINV include gender, age, and alcohol intake. It is important to assess the emetogenicity of chemotherapy regimens as well as the potential impact of patient risk factors in order to provide adequate prophylaxis. Acute and delayed CINV are severe, burdensome side effects of chemotherapy; however, new data on prevention and the discovery of new agents can further improve CINV control.

    Postoperative urinary retention (POUR) is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%), 3 patients in Group II (5%) and 4 patients in Group III (6.7%) required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006). The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697). This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

    The ubiquitous and opportunistic bacterial pathogen Aeromonas hydrophila has been associated with ulcerative dermatitis in fish, especially under stressful conditions. It can cause severe losses in fresh water aquaculture and is particularly prevalent in tropical and subtropical regions. Fresh leaves from maize and bananas have been used as feed supplement by fish farmers in Vietnam and it has been reported that they may have phyto-prophylactic benefits. In the present study, a feeding trial was conducted to investigate the benefits of providing maize and banana leaves as feed supplement: to determine if they were taken up and digested by grass carp (Ctenopharyngodon idella), if this uptake resulted in improved growth performance, and if leaf supplementation protected fish when challenged with A. hydrophila by intramuscular injection. All fish were fed an identical ratio of commercial pelleted feed relative to biomass. However, in 12/18 tanks, this diet was supplemented with either fresh banana leaves or fresh maize leaves; offered ad libitum. Addition of leaves increased the overall feed conversion ratio (FCR) significantly. However, if only the pellet were taken into account, then no difference was found between treatments. Changes to the isotopic composition of the fish showed leaf nutrient uptake occurred. No prophylactic effects of feeding banana or maize leaves were detected against infection with A. hydrophila, and the diet did not induce changes in the fish haematocrit. However, addition of the maize leaves was associated with significantly reduced severity of the skin lesions, which could improve the market value of the fish. Addition of the leaf supplement did not result in significantly improved growth performance. Similarly, the effect of the supplement on the fish survival to infection was not significant.

    Zingiber officinale (ZO, family Zingiberaceae) has been reported for its antiemetic activity against cancer chemotherapy induced emesis in animal models and in clinics. Current study was designed to investigate ZO for potential usefulness against cisplatin induced vomiting in pigeon and its effects on central and peripheral neurotransmitters involved in the act of vomiting. Zingiber officinale acetone fraction (ZO-ActFr) was investigated for attenuation of emesis induced by cisplatin in healthy pigeons. Neurotransmitters DA, 5HT and their metabolites DOPAC, HVA and 5HIAA were analyzed using High Performance Liquid Chromatography system coupled with electrochemical detector in area postrema, brain stem and intestine. Antiemetic effect of ZO-ActFr was correlated with central and intestinal neurotransmitters levels in pigeon. Cisplatin (7 mg/kg i.v.) induced emesis without lethality upto the observation period. ZO-ActFr (25, 50 & 100 mg/kg) attenuated cisplatin induced emesis ~ 44.18%, 58.13% (P < 0.05) and 27.9%, respectively; the reference drug, metoclopramide (MCP; 30 mg/kg), produced ~ 48.83% reduction (P < 0.05). ZO-ActFr reduced (P < 0.05 - 0.001) 5-hydroxytryptamine (5HT) concentration in the area postrema, brain stem and intestine at 3(rd) hour of cisplatin administration, while at the 18(th) hour ZO treatments attenuated the dopamine upsurge (P < 0.001) caused by cisplatin in the area postrema and 5HT concentration (P < 0.01 - 0.001) in the brain stem and intestine. ZO treatments alone did not altered the basal neurotransmitters and their metabolites in the brain areas and intestine. The behavioral study verify the antiemetic profile of ZO against cisplatin induced emesis in the pigeon, where central and peripheral neural evidences advocate the involvement of serotonergic mechanism at initial time point (3(rd) hr), while the later time point (18(th) hr) is associated with serotonergic and dopaminergic component in the mediation

    Full Text Available Background and purpose: Antiemetic guidelines suggest daily prophylaxis with a serotonin3 receptor antagonist (5-HT3RA as an option for patients receiving long-course neoadjuvant radiation therapy and concurrent 5-fluorouracil-based chemotherapy for rectal cancer, despite the risks that 5-HT3RA-induced constipation may pose. We explored the incidence of patient-reported vomiting, retching, nausea and antiemetic intake among patients in this setting to determine if these risks are justified. Materials and methods: We carried out a single-centre non-randomised prospective cohort study of adult patients receiving long-course neoadjuvant radiation therapy and concurrent 5-fluorouracil-based chemotherapy for rectal adenocarcinoma. Patients recorded symptoms and medication intake daily until 7 days following treatment completion. Results: From 33 evaluable patients, we collected 1407 days of patient-reported data. Vomiting was reported by 7 patients (21%, retching by 5(15% and nausea by 21(64%. No patients were administered prophylactic antiemetics. The median number of days with vomiting was 2, and the cumulative number of days for all affected patients was 22 (1.6% of 1407 evaluable days. There were no differences in PTV or small bowel loop V15Gy, V45Gy and V50Gy volumes between patients that did and did not vomit. Conclusions: The cumulative incidence of days with vomiting was only 1.6%. 5-HT3RA prophylaxis during long-course neoadjuvant treatment seems unnecessary.

    The most frequent recurrence site of papillary thyroid carcinoma (PTC) is the cervical lymph nodes. The introduction of an electric linear probe for use with ultrasonography in 1996 improved preoperative lateral neck evaluations. Before 2006, however, our hospital routinely performed prophylactic modified neck dissection (p-MND) for N0 or N1a PTCs >1 cm to prevent node recurrence. In 2006, we changed our policy and the indications for p-MND to PTCs >3 cm and/or with significant extrathyroid extension. Here, we retrospectively compared lymph node recurrence-free survival between PTCs with/without p-MND. We examined the cases of N0 or N1 and M0 PTC patients who underwent initial surgery in 1992-2012. To compare lymph node recurrence-free survival between patients who did/did not undergo p-MND, we divided these patients into three groups (excluding those whose surgery was in 2006): the 2045 patients whose surgery was performed in 1992-1996 (Group 1), the 2989 with surgery between 1997 (post-introduction of ultrasound electric linear probes) and 2005 (Group 2), and the 5332 operated on in 2007-2012 (Group 3). The p-MND performance rate of Group 3 (9%) was much lower than that of Group 1 (80%), but the lymph node recurrence-free survival of the former was significantly better, probably due to differences in clinical features and neck evaluations by ultrasound between the two groups. Our analysis of the patients aged Abolishing routine p-MND for PTCs in 2006 did not decrease lymph node recurrence-free survival, probably due to improved ultrasound preoperative neck evaluations and clinical feature changes. Selective p-MND for high-risk cases improved lymph node recurrence-free survival.

    Full Text Available Preventive therapy in migraine constitutes an important aspect of migraine management especially in patients who are not controlled or have significant disability despite taking drugs for acute management. In spite of te recent advances in understanding of the pathophysiology of migraine, the mechanisms of action of many preventive drugs are largely unknown. Further, these provide only about 50% reduction in frequency in about 2/3rds of migraine sufferers. Hence, risk-benefit ratio must be considered while prescribing these agents. Recent efforts to undertake large-scale meta-analysis to assess the efficacy of these agents have been rewarding and consensus guidelines have evolved. Propanolol, metoprolol, amitriptyline, sodium valproate, flunarizine and lisuride have emerged as first line drugs. The role of newer anti-convulsants and botox injections in refractory cases are being investigated. Availability, co-morbidities, medical contraindications, concomitant acute therapy and costs are important determinants for choosing a particular agent. This article reviews the guidelines to be followed in choosing the prophylactic treatment options for migraine.

    DNA-spermidine (DA-51), which has been originally developed by Dr. Sekiguchi et al. as a protective agent against radiation-induced leukopenia, was submitted to clinical trial by the double blind test. The protective effect against radiation-induced leukopenia and side effect of DA-51 were compared with those of Inosine, selected as a control agent, on breast cancer cases receiving prophylactic irradiation. Daily dose of 2700 mg of DA-51 and 1800 mg of Inosine were administered orally during a 5 week period of irradiation. The differences between the white blood cell counts, the thrombocyte counts and the percentages of lymphocytes in the DA-51 and the Inosine treated groups were assessed at 1, 3 and 5 weeks by x/sup 2/ and T tests, and the following results are obtained: No significant difference in white blood cell or thrombocyte counts was demonstrated at 1, 3 or 5 weeks between the two groups. The only significant difference noted was in the percentage of lymphocyte at 5 weeks, and the thrombocyte counts at 3 weeks. DNA-spermidine is considered to be an effective drug against radiation-induced leukopenia, comparable to Inosine and without noticeable side effects.

    Full Text Available Background: Radio frequency wave (RFW generated by base transceiver station (BTS has been reported to make deleterious effects on liver and kidney, possibly through oxidative stress. This study was conducted to evaluate the effect of radiofrequency wave (RFW-induced oxidative stress in the liver and kidney and the prophylactic effect of vitamin C on this organs by measuring the antioxidant enzymes activity including: glutathione peroxidase (GPx, superoxide dismutase (SOD and catalase (CAT, and malondialdehyde (MDA. Materials and Methods: In this experimental study, thirty-two adult male Sprague-Dawley rats were randomly divided into four experimental groups and treated daily for 45 days as follows: control, vitamin C (L-ascorbic acid 200 mg/kg of body weight/day by gavage, test (exposed to 900MHz RFW and the treated group (received vitamin C in addition to exposure to RFW. At the end of the experiment all animals were sacrificed and their liver and kidney were removed and were used for measurement of antioxidant enzymes and MDA activity. Results: The results indicate that exposure to RFW in the test group decreased antioxidant enzymes activity and increased MDA compared with the control groups (p<0.05. In the treated group vitamin C improved antioxidant enzymes activity and reduced MDA compared to the test group (p<0.05. Conclusion: It can be concluded that RFW causes oxidative stress in liver and kidney, and vitamin C improves the antioxidant enzymes activity and decreases MDA.

Methods: Randomized controlled trials and cohort studies comparing PPIs with H2RAs in adults receiving DAPT were collected from PubMed, EMBASE and Cochrane databases. Dichotomous data were pooled to obtain risk ratios (RRs for UGIB, major adverse cardiovascular events (MACEs, poor responders to clopidogrel and rehospitalization, and continuous data were pooled to obtain mean differences (MDs for P2Y12 reaction units (PRUs, with 95% confidence intervals (CIs. Results: Twelve clinical trials (n=3,301 met the inclusion criteria. Compared to H2RAs, PPIs lessened UGIB (RR =0.16, 95% CI: 0.03–0.70, and there was no significant difference in the incidence of PRUs (MD =18.21 PRUs, 95% CI: -4.11–40.54, poor responders to clopidogrel (RR =1.21, 95% CI: 0.92–1.61, incidence of MACEs (RR =0.89, 95% CI: 0.45–1.75 or rehospitalization (RR =1.76, 95% CI: 0.79–3.92. Subgroup analysis confirmed fewer PRUs in the H2RAs group compared to the omeprazole group (2 studies, n=189, MD =31.80 PRUs, 95% CI: 11.65–51.96. However, poor responder data for clopidogrel and MACEs might be unreliable because few studies of this kind were included. Conclusion: Limited evidence indicates that PPIs were better than H2RAs for prophylaxis of UGIB associated with DAPT and had no effect on platelet function. Further study is needed to confirm these observations. Keywords: proton pump

    2014-01-01

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter (OTC) analgesics. Diclofenac is an established analgesic, and new formulations using the potassium or epolamine salts, which can be dissolved in water, have been developed for rapid absorption, which may be beneficial in acute migraine. Co-therapy with an antiemetic should help to reduce the nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of diclofenac, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, ClinicalTrials.gov, and reference lists for studies through 27 September 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using self administered diclofenac to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Five studies (1356 participants) compared oral diclofenac with placebo, and one also compared it with sumatriptan; none combined diclofenac with a self administered antiemetic. Four studies treated attacks with single doses of medication, and two allowed an optional second dose for inadequate response. Only two studies, with three active treatment arms, provided data for pooled analysis of primary outcomes. For single doses of diclofenac

    A field trial was carried out during a summer-fall period on a commercial beef cattle farm in Minas Gerais State, located in the Southeast of Brazil. In order to evaluate the prophylactic effect and the curative efficacy of fipronil in a 1% solution, 200 Zebu crossbred bulls, with ages varying from 20 to 30 months and weights from 233 to 362 kg, were selected. The bulls were assigned by ranked pair to an untreated control group (A) or to a treated group (B), resulting in 100 animals per group. All experimental animals were surgically castrated on day 0, following routine procedures. After castration all animals in the group B were treated with 10 mg/kg bw of a 1% fipronil solution, topically on the dorsal mid-line. The wounds were individually inspected on days: 2, 4, 7, 10, 14, 17, 21, 28 and 35. After castration the animals were naturally exposed to Cochliomyia hominivorax and remained in the same pasture throughout the trial. Among the animals in the control group, 83 were observed to harbor C. hominivorax eggs, with a total of 97 ovipositions, and among those 73 animals had active myiasis. In group B (fipronil 1%), 66 animals showed C. hominivorax eggs, with 92 ovipositions and five animals with active myiasis. Most ovipositions and active myiasis were detected until seven days post-castration for both groups. Wound parasite infestation evidenced bleeding, serous purulent exudation and presence of active C. hominivorax larvae. Treatment with fipronil 1% had a prophylactic effect on scrotal wounds against the development of C. hominivorax larvae in more than 95% of the treated animals for up to 17 days after castration. The treatment showed partial protection of 66% and 50% on days 21 and 28 post-treatment (pt), respectively. Three animals from the control group and one from the treated group showed active screwworms on day 21 pt, and one animal from the treated group and two from the control group also presented C. hominivorax larvae on scrotal wounds on day 28

    This study was conducted to evaluate the effect of radiofrequency wave (RFW)-induced oxidative stress in the eye and the prophylactic effect of vitamin C on this organ by measuring the antioxidant enzymes activity including: glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT), and malondialdehyde (MDA). Thirty-two adult male Sprague-Dawley rats were randomly divided into four experimental groups and treated daily for 45 days as follows: Control, vitamin C (L-ascorbic acid 200 mg/kg of body weight/day by gavage), test (exposed to 900 MHz RFW) and the treated group (received vitamin C in addition to exposure to RFW). At the end of the experiment all animals were sacrificed, their eyes were removed and were used for measurement of antioxidant enzymes and MDA activity. The results indicate that exposure to RFW in the test group decreased antioxidant enzymes activity and increased MDA compared with the control groups (P < 0.05). In the treated group vitamin C improved antioxidant enzymes activity and reduced MDA compared to the test group (P < 0.05). It can be concluded that RFW causes oxidative stress in the eyes and vitamin C improves the antioxidant enzymes activity and decreases MDA.

    Prophylaxis with plasma-derived or recombinant activated factor VII is beneficial in severe factor VII deficiency. To understand why prophylactic treatment with both products is efficacious, we conducted a pharmacokinetic study. Ten factor VII deficient patients were treated with either recombinant activated (20 μg/kg) or plasma-derived (25 IU/kg) factor VII in a cross-over design. Pharmacokinetic parameters were analyzed through activated factor VII activity, factor VII clotting activity, and factor VII antigen levels on depicted time points. Factor VII activity half-lifes, determined by non-compartmental and one-compartmental analysis (results in brackets), were shorter for recombinant activated (1.4h; 0.7h) than for plasma-derived factor VII (6.8h; 3.2h); both recombinant activated (5.1h; 2.1h and plasma-derived factor VII (5.8h; 3.2h) resulted in longer half-lives of factor VII antigen. Activated factor VII half-lives (based on activated factor VII activity levels) were significantly higher compared to factor VII clotting activity (1.6h; 0.9h). Volumes of distribution were significantly higher for activated factor VII (236 ml/kg; 175 ml/kg, measured by activated factor VII) as compared to plasma-derived factor VII (206 ml/kg; 64 ml/kg, measured by factor FVII activity), suggesting a plasma- and extracellular fluid distribution for recombinant activated factor VII. Recombinant activated factor VII showed significantly shorter half-lifes than plasma-derived factor VII. Volumes of distribution were significantly higher for treatment with recombinant activated factor VII. The longer half-life for plasma-derived factor VII, compared to recombinant activated factor VII, and the increased volume of distribution for recombinant activated factor VII, compared to plasma-derived factor VII may further elucidate the beneficial effect of prophylactic treatment of both products.

  18. The Effect of Transdermal Scopolamine for the Prevention of Postoperative Nausea and Vomiting

    Directory of Open Access Journals (Sweden)

    Maria A. Antor

    2014-04-01

    Full Text Available Postoperative nausea and vomiting is one of the most common and undesirable complaints recorded in as many as 70%-80% of high-risk surgical patients. The current prophylactic therapy recommendations for PONV management stated in the Society of Ambulatory Anesthesia guidelines should start with monotherapy and patients at moderate to high risk, a combination of antiemetic medication should be considered. Consequently, if rescue medication is required, the antiemetic drug chosen should be from a different therapeutic class and administration mode than the drug used for prophylaxis. The guidelines restrict the use of dexamethasone, transdermal scopolamine, aprepitant, and palonosetron as rescue medication 6 hours after surgery. In an effort to find a safer and reliable therapy for postoperative nausea and vomiting, new drugs with antiemetic properties and minimal side effects are needed, and scopolamine may be considered an effective alternative. Scopolamine is a belladonna alkaloid, α-(hydroxymethyl benzene acetic acid 9-methyl-3-oxa-9-azatricyclo non-7-yl ester, acting as a nonselective muscarinic antagonist and producing both peripheral antimuscarinic and central sedative, antiemetic, and amnestic effects. The empirical formula is C17H21NO4 and its structural formula is a tertiary amine L-(2-scopolamine (tropic acid ester with scopine; MW = 303.4. Scopolamine became the first drug commercially available as a transdermal therapeutic system used for extended continuous drug delivery during 72 hours. Clinical trials with transdermal scopolamine have consistently demonstrated its safety and efficacy in postoperative nausea and vomiting. Thus, scopolamine is a promising candidate for the management of postoperative nausea and vomiting in adults as a first line monotherapy or in combination with other drugs. In addition, transdermal scopolamine might be helpful in preventing postoperative discharge nausea and vomiting owing to its long

However, HRs for OS favored non-PCI (HR = 1.19, 95% [CI]: 1.06-1.33, p = 0.004, without evidence of heterogeneity between the studies.Our results suggest that although PCI decreased the risk of BM, it may impose a detrimental effect on OS of NSCLC patients.

  1. Dronabinol for chemotherapy-induced nausea and vomiting unresponsive to antiemetics

    2016-01-01

    Chemotherapy-induced nausea and vomiting (CINV) is one of the most common symptoms feared by patients, but may be prevented or lessened with appropriate medications. Several antiemetic options exist to manage CINV. Corticosteroids, serotonin receptor antagonists, and neurokinin receptor antagonists are the classes most commonly used in the prevention of CINV. There are many alternative drug classes utilized for the prevention and management of CINV such as antihistamines, benzodiazepines, anticonvulsants, cannabinoids, and dopamine receptor antagonists. Medications belonging to these classes generally have lower efficacy and are associated with more adverse effects. They are also not as well studied compared to the aforementioned agents. This review will focus on dronabinol, a member of the cannabinoid class, and its role in CINV. Cannabis sativa L. (also known as marijuana) contains naturally occurring delta-9-tetrahydrocannibinol (delta-9-THC). The synthetic version of delta-9-THC is the active ingredient in dronabinol that makes dronabinol an orally active cannabinoid. Evidence for clinical efficacy of dronabinol will be analyzed in this review as monotherapy, in combination with ondansetron, and in combination with prochlorperazine

  2. Palonosetron as an anti-emetic and anti-nausea agent in oncology.

    Palonosetron (Aloxi(®), Onicit(®), Paloxi(®)) is a second-generation 5-HT(3) receptor antagonist (RA) with an extended half-life of ~40 hours and high binding affinity for the 5-HT₃ receptor that is markedly different from other 5-HT(3) RAs. Phase III trials demonstrate that a single dose of palonosetron compared with traditional 5-HT₃ RAs is more effective in preventing chemotherapy-induced nausea and vomiting (CINV) during the first 24 hours following chemotherapy (acute CINV), and also exhibits prolonged efficacy to provide significantly better protection from CINV in the delayed and overall phases. This superior and extended protection from CINV conferred by palonosetron following a single intravenous dose before chemotherapy simplifies dosing schedules. Recent research has focused on optimization of palonosetron-based antiemetic regimens, particularly in combination with steroids and neurokinin-1 RAs. The available clinical data indicate high control rates for palonosetron, suggesting a synergistic potential for protection in patients scheduled to receive emetogenic drug regimens.

    Prophylactic digoxin is widely used in patients undergoing pulmonary surgery to prevent or control cardiac arrhythmias, but whether it is helpful or not is uncertain. An open, controlled randomised prospective clinical study of 111 patients was undertaken to compare the incidence of cardiac arrhythmias in the 58 patients who received preoperative digoxin and the 53 who did not. Cardiac arrhythmia occurred in half (29/58) of those given prophylactic digoxin and in 36% (19/53) of those who were not. The overall incidence of arrhythmia was 43%, with no statistically significant difference between the groups. Cardiac arrhythmias remain an important complication of pulmonary surgery and the incidence is not reduced by prophylactic digoxin.

    There has been an increasing trend in the use of contralateral prophylactic mastectomy (CPM) in the United States among women diagnosed with unilateral breast cancer, particularly young women. Approximately one-third of women CPM in the US. Most studies have shown that the CPM trend is mainly patient-driven, which reflects a changing environment for newly diagnosed breast cancer patients. The most common reason that women choose CPM is based on misperceptions about CPM’s effect on survival and overestimation of their contralateral breast cancer (CBC) risk. No prospective studies have shown survival benefit to CPM, and the CBC rate for most women is low at 10 years. Fear of recurrence is also a big driver of CPM decisions. Nonetheless, studies have shown that women are mostly satisfied with undergoing CPM, but complications and subsequent surgeries with reconstruction have been associated with dissatisfaction with CPM. Studies on surgeon’s perspectives on CPM are sparse but show that the most common reasons surgeons discuss CPM with patients is because of a suspicious family history or for a patient who is a confirmed BRCA mutation carrier. Studies on the cost–effectiveness of CPM have been conflicting and are highly dependent on patient’s quality of life after CPM. Most recent guidelines for CPM are contradictory. Future areas of research include the development of interventions to better inform patients about CPM, modification of the guidelines to form a more consistent statement, longer term studies on CBC risk and CPM’s effect on survival, and prospective studies that track the psychosocial effects of CPM on body image and sexuality.

    Pre-operative prophylactic antibiotics may decrease the frequency of surgical site infection after appendectomy. However, the optimal timing for administration of pre-operative prophylactic antibiotics is unknown. The purpose of this study was to evaluate the effect of timing of prophylactic antibiotics on the frequency of surgical site infection after appendectomy. Medical records were reviewed retrospectively for 577 consecutive patients who had appendectomy for acute appendicitis from 2006 to 2009. Quality assurance guidelines for timing of prophylactic antibiotics before the skin incision were changed from 0 to 30 min before the skin incision (before June 2008) to 30 to 60 min before the skin incision (after June 2008). Surgical site infection occurred in 28 patients (4.9%). There was no difference in frequency of surgical site infection with different timing of pre-operative prophylactic antibiotic (pre-operative time 0 to 30 min: 9 infections [3.6%]; 31 to 60 min: 13 infections [5.4%]; 61 to 120 min: 5 infections [7.0%]; >120 min: 1 infection [6.6%]). Multivariable analysis showed that surgical site infection was associated significantly with medical comorbidity but not perforated appendicitis. The frequency of surgical site infection was independent of timing of preoperative prophylactic antibiotics but was associated with the presence of medical comorbidity.

  7. Comparison of the effectiveness of ''late'' and ''early'' prophylactic cranial irradiation in patients with limited-stage small cell lung cancer

    2010-01-01

    Purpose: to evaluate the effectiveness of timing of application of prophylactic cranial irradiation (PCI) in patients with small cell lung cancer in limited stage of disease (LS SCLC). Patients and methods: between 1995 and 2004, 129 patients with LS SCLC were treated within two consecutive phase II studies assessing different schedules of combined treatment. All patients received chemotherapy and concurrent thoracic radiotherapy. In 86 patients (66.7%) who developed complete response in the thorax, PCI was performed either after chemoradiotherapy (''late'' PCI, n = 45 [52.4%]) or during chemoradiotherapy (''early'' PCI, n = 41 [47.7%]). In the latter case, PCI was given immediately after the end of thoracic radiotherapy and prior to the last cycles of chemotherapy to a total dose of 30 Gy in 2-Gy fractions to the whole brain. The results were evaluated with regard to 4-year rates of overall survival, disease-free survival, and brain metastases-free survival. Additionally, the prognostic role of PCI application and its time delay in relation to survival rates and incidence of brain metastases was estimated. Results: the 4-year survival rates were 25.5% for overall survival, 26.8% for disease-free survival, and 67.8% for brain metastases-free survival. During the observation period, 32 patients (24.8%) developed brain metastases, which occured in 20 of 43 patients (46.5%) without and only in twelve out of 86 patients (14%) with PCI. The 4-year brain metastases-free survival rates were 81.8%, if PCI was applied, versus 32.2%, if no such procedure was used (for p = 0.0000). The timing of PCI appeared to be an important factor in terms of decreasing the incidence of brain metastases. Conclusion: PCI significantly decreases the incidence of brain metastases and delays their development in patients with LS SCLC. ''Early'' PCI is more effective than PCI applied after combined therapy. (orig.)

    Full Text Available Objectives: Postoperative nausea and vomiting (PONV is one of the most frequent adverse effects of anesthesia. PONV postpones hospital stays and also delays recover and getting better, of the patients. The objective of the current study is to compare efficacy of prophylactic granisetron(40 μ/kg + dexamethasone (4 mg combination against PONV in different anesthesia models.Materials and Methods: 72 patients with an age range of 18-72 years and ASA 1 or 2 were enrolled in the present study. The patients were assigned as group 1 propofol-remifentanil (P-R, group 2 propofol- nitrous oxide (P-N2O, group 3 sevoflurane- nitrous oxide (S-N2O and group 4 sevoflurane-remifentanyl-air (S-R+H. Inductions of the patients in all groups were made with intravenous 2-3 mg/kg propofol, 1μ/kg remifentanil and 0.2 mg/kg cis-atracurium. 4 mg of dexamethasone by bolus and 40 μ/kg of granisetron by infusion were administered to the patients in all groups after induction. During the last 10 minutes of the operation, 1mg/kg tramadol was administered.Postoperative nausea and vomiting, VAS scores, and additional antiemetic needs were recorded during postoperative 48 hours.Results: Postoperative 48 hours follow up revealed that PONV was seen 27%, 16%, 38%, 48% frequencies in (P+R, (P+ N2O, (S+ N2O, (S+R+H groups, respectively.While antiemetic requirement was not observed in (P+ N2O and (S+ N2O groups, the patients in (P+R and (S+R+H groups needed additional antiemetic drugs with a frequency of 5.5% and 11% respectively.Conclusion: Granisetron, dexamethasone combination in different anesthetic models did not reveal significant difference in terms of postoperative nausea, vomiting, and additional antiemetic usage.

    The effect of central nervous system prophylaxis (cranial radiation and intrathecal chemotherapy) on intellectual function was studied in 24 children with acute lymphocytic leukemia. The Wechsler Intelligence tests were administered to these children and to a sample of their healthy siblings, who served as a comparison group. The mean Full Scale lQ was 98.6 for the patients and 112.5 for the sibling controls (p less than 0.001 level). Those patients who received central nervous system preventive treatment at a young age exhibited a greater decrement in intellectual abilities than did patients who were older when they received this treatment. In contrast, leukemia patients who had not received central nervous system prophylaxis had IQs that did not differ statistically from those of their siblings. These data suggest that central nervous system prophylaxis may have an adverse effect on the intellectual capability of children with acute lymphocytic leukemia

    Full Text Available Background : The most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP is acute pancreatitis. A number of therapeutic trials have been studied due to reduce the occurrence of postendoscopic retrograde cholangiopancreatography pancreatitis (PEP but many of them were unsuccessful. Periampullary corticosteroid injection was proposed to use as prophylactic agents for PEP because of its anti-inflammatory property with relative low systemic side effects. Materials and Methods : By conducting a double blinded clinical trial study in a single center university hospital, all patients undergoing therapeutic or diagnostic ERCP in our gastrointestinal endoscopy ward, enrolled the study. During ERCP, we randomly assigned the patients in blocks of 40 to undergo a locally injection of methylprednisolone acetate (corticosteroid group or saline (control group on the major papilla and prospectively evaluated the occurrence of PEP pancreatitis in each groups. Clinical and laboratory findings of acute pancreatitis were collected by means of a validated questionnaire during the procedure and before discharge. At baseline and end of the study, were compared pancreatitis prevalence and also its severity by using Chi-square and t-test statistics. Results : The frequency of moderate to severe PEP pain was not significantly between the placebo and corticosteroid receiving group (13.7% ± 3.2% vs. 9.3% ± 2.1%, respectively; P = 0.8. There is no significant difference in the mean concentration of lipase and amylase between corticosteroid receiving group and placebo receiving group at the first, second, and third time. In the corticosteroid receiving group, 3 patients (10.3% while in the control group, 11 patients (11.3% developed pancreatitis. Conclusion: We found no significant difference in PEP rates and also severity between the corticosteroid and placebo groups. The mean increase in serum amylase and amylase level

    Full Text Available Because microaspiration of contaminated supraglottic secretions past the endotracheal tube cuff is considered to be central in the pathogenesis of pneumonia, improved design of tracheal tubes with new cuff material and shape have reduced the size and number of folds, which together with the addition of suction ports above the cuff to drain pooled subglottic secretions leads to reduced aspiration of oropharyngeal secretions. So we conducted a study to compare the prophylactic effects of polyurethane-cylindrical or tapered cuff and polyvinyl chloride cuff endotracheal tubes (ETT on ventilator-associated pneumonia. This randomized clinical trial was carried out in a 12 bed surgical intensive care unit. 96 patients expected to require mechanical ventilation more than 96 hours were randomly allocated to one of three following groups: Polyvinyl chloride cuff (PCV ETT, Polyurethane (PU cylindrical Sealguard ETT and PU Taperguard ETT. Cuff pressure monitored every three hours 3 days in all patients. Mean cuff pressure didn't have significant difference between three groups during 72 hours. Pneumonia was seen in 11 patients (34% in group PVC, 8 (25% in Sealguard and 7 (21% in Taperguard group. Changes in mean cuff pressure between Sealguard and PVC tubes and also between Taperguard and PVC tubes did not show any significant difference. There was no significant difference in overinflation between three groups. The use of ETT with PU material results in reducing ventilator-associated pneumonia compared to ETT with PVC cuff. In PU tubes Taperguard has less incidence of ventilator-associated pneumonia compared to Sealguard tubes.

    The objective of this study was to investigate the protective effects of pomegranate (Punica granatum) juice (PGJ) on oxidative damages in liver tissue and erythrocytes of rats intoxicated by sodium fluoride (NaF). Rats were randomly divided into two groups: group I received standard diet and group II received orally 1 mL of PGJ. After 5 weeks of pretreatment, each group was divided again into two subgroups and treated for another 3 weeks as follows: group I was subdivided into a control group and a group that was treated with 100 ppm of NaF (in drinking water); group II was subdivided into one group that was treated daily with both 100 ppm NaF and PGJ (1 mL orally) and one that received daily 1 mL of pomegranate juice. Exposure to NaF decreased hematological parameters, changed the total protein, albumin, bilirubin levels, and increased the activities of hepatic marker enzymes. We also noted an increase in lipid peroxidation contents, accompanied by a decrease of reduced glutathione levels. Antioxidant enzyme activities in both tissues were modified in the NaF group compared with the control group. However, the administration of PGJ juice caused an amelioration of the previous parameters. Our results indicated the potential effects of NaF to induce oxidative damage in tissues and the ability of PGJ to attenuate NaF-induced oxidative injury.

    Full Text Available Abstract Background: Probiotics are known as a factor for prevention of infectious diseases such as urinary tract infection(UTI. The present study aimed to investigate the positive effects of probiotics on urinery truct infection of cateterized intensive care unit patients. Materials and Methods: In a triple blind clinical trial, 125 cateterized intensive care unit patients were randomly selected and divided into two groups, Treatment group (n = 63 was well matched with placebo group (n = 62 for age and sex and duration of admission .Case group received one lactocare capsule for 10 days and control group with a same method received placebo for 10 days. In both groups urine analysis and urine culture were measured with a same method at the first day and then twentieth day and finally data were analysed with t-test. Results: The incidence of urinary tract infection between treatment and control group (respectively 17.4% and 22.5% had no statistically significant difference (p=0.672. But, in terms of sex, incidence of urinary tract infections in women compared to men with the same condition was significantly different(p=0.002. In treatment group with long term cathetrization, urinary tract infections significantly were significantly different(p=0.041. Conclusion: Administration of lactocare capsule has no statistically significant impact on the incidence of urinery truct infection of cateterized intensive care unit patients. In comparsion of cateterized men and women receiving probiotics, the reduction of urinary tract infection in women was more than in men. Probiotics had preventive effects on long term catheterization.

    To determine whether topical hypotensive medications prevent postoperative ocular hypertension (POH) after phacoemulsification. 52 client-owned dogs (88 eyes). Diabetic and nondiabetic dogs having undergone phacoemulsification were included in this retrospective study. The control group received no ocular hypotensive medications. The treatment groups received latanoprost, dorzolamide, or dorzolamide/timolol, beginning immediately after surgery, for 2-week duration. IOPs were obtained at initial examination followed by 4 h, 24 h, 7 days, and 14 days postoperatively. POH was defined as an IOP above 20 mmHg (POH20) or 25 mmHg (POH25). POH20 occurred in 33 of 87 eyes (37.93%), including 11 of 21 eyes (52.38%) in the control group, three of 23 eyes (13.04%) in the latanoprost group, eight of 15 eyes (53.33%) in the dorzolamide group, and 11 of 28 eyes (39.29%) in the dorzolamide/timolol group. Active treatment groups were compared to the control group, and the overall group effect was not significant (P = 0.11). POH25 occurred in 22 of 86 eyes (25.58%), including seven of 21 eyes (33.33%) in the control group, two of 23 eyes (8.70%) in the latanoprost group, five of 15 eyes (33.33%) in the dorzolamide group, and eight of 27 eyes (29.63%) in the dorzolamide/timolol group. Active treatment groups were compared to the control group, and the overall group effect was not significant (P = 0.31). Intraoperative use of intracameral tissue plasminogen activator significantly decreased the chances of POH25 (P = 0.0063). The latanoprost group had a substantially lower percentage of POH 20 and POH25 compared to the control and other active treatment groups, although statistical significance was not achieved. Intraoperative intracameral tissue plasminogen activator decreased the incidence of POH25. © 2017 American College of Veterinary Ophthalmologists.

    Acute gastroenteritis (AG) represents both the main cause of acute vomiting in children under 3 years old and a major cause of access to the emergency department. Even if several drugs may be able to reduce the emesis, the pharmacological treatment of vomiting in children remains a controversial issue, and several drugs are prescribed outside their authorized drug label with respect dosage, age, indication, or route of administration and are named as off-label. The aim of present study was to assess the off-label use of antiemetic drugs in patients less than 18 years with vomiting related to AG. This study was carried out in eight pediatric emergency departments in Italy. The following data were obtained crossing the pharmacy distribution records with emergency departments' patient data: sex and age of the patients and detailed information for each drug used (indication, dose, frequency, and route of administration). We recorded that antiemetic drugs were prescribed in every year, particularly in children up to 2 years old, and compared with both literature data and data sheet; 30 % of the administered antiemetics were used off-label. In particular, domperidone was the only antiemetic used labeled for AG treatment in pediatric patients, while metoclopramide and ondansetron have been off-label for both age and indications (i.e., AG treatment). In conclusion, we documented an off-label use of antiemetics in children, and this could represents a problem of safety for the patient and a legal risk for the prescribing physician if patients have an unwanted or bad outcome from treatment.

    Recently, concurrent chemoradiotherapy (CCRT) is frequently used for the treatment of oropharyngeal cancer. However, CCRT induces mucositis and dysphagia and causes inadequate oral nutrition intake. Thus, percutaneous endoscopic gastrostomy (PEG) in advance is recently recommended. To evaluate the effectiveness of PEG on nutritional intake, nutritional status, blood test, and grade of mucositis of 29 patients who had CCRT with PEG were investigated retrospectively. The results were statistically compared with those of 13 patients who had CCRT without PEG as a control group. Regarding the total energy, no significant change was observed in the PEG group, while the total energy intake significantly decreased in the control group (P=0.026). A significant correlation was observed between the rate of body weight loss during CCRT and total energy intake (R=0.78). The total energy intake of patients who could maintain body weight was 34.1 kcal/kg/day. Taken together, these results suggested that early nutritional administration using PEG can reduce the weight loss during CCRT. (author)

Follow-up was performed via record linkage and two parent-completed validated questionnaires, the Child Development Inventory and the Health Utilities Index.Record linkage was successfully performed on at least one record in 759/781 (97% children eligible for follow-up. There were no differences between progesterone-exposed and placebo-exposed twins with respect to incidence of death, congenital anomalies and hospitalisation, nor on routine national child health assessments. Questionnaire responses were received for 324/738 (44% children. The mean age at questionnaire follow-up was 55.5 months. Delay in at least one developmental domain on the Child Development Inventory was observed in 107/324 (33% children, with no evidence of difference between progesterone-exposed and placebo-exposed twins. There was no evidence of difference between the progesterone and placebo groups in global health status assessed using the Health Utilities Index: 89% of children were rated as having 'excellent' health and a further 8% as having 'very good' health.In this cohort of twin children there was no evidence of a detrimental or beneficial impact on health and developmental outcomes at three to six years of age due to in utero exposure to progesterone.

    In this study we compared the efficacy and safety of three antiemetic combinations in the prevention of postoperative nausea and vomiting (PONV). Ninety ASA status I-II women, aged 18-65 yr, undergoing general anesthesia for major gynecological surgery, were included in a prospective, randomized, double-blinded study. A standardized anesthetic technique and postoperative analgesia (intrathecal morphine plus IV patient-controlled analgesia (PCA) with morphine) were used in all patients. Patients were randomly assigned to receive ondansetron 4 mg plus droperidol 1.25 mg after the induction of anesthesia and droperidol 1.25 mg 12 h later (Group 1, n = 30), dexamethasone 8 mg plus droperidol 1.25 mg after the induction of anesthesia and droperidol 1.25 mg 12 h later (Group 2, n = 30), or ondansetron 4 mg plus dexamethasone 8 mg after the induction of anesthesia and placebo 12 h later (Group 3, n = 30). A complete response, defined as no PONV in 48 h, occurred in 80% of patients in Group 1, 70% in Group 3, and 40% in Group 2 (P = 0.004 versus Groups 1 and 3). The incidences of side effects and other variables that could modify the incidence of PONV were similar among groups. In conclusion, ondansetron, in combination with droperidol or dexamethasone, is more effective than dexamethasone in combination with droperidol in women undergoing general anesthesia for major gynecological surgery with intrathecal morphine plus IV PCA with morphine for postoperative analgesia. The combination of ondansetron plus dexamethasone or droperidol was significantly better than the combination of dexamethasone plus droperidol in the prophylaxis of postoperative nausea and vomiting in women undergoing general anesthesia for major gynecological surgery, with intrathecal and IV morphine (patient-controlled analgesia) for management of postoperative pain.

    We conducted a clinical trial to determine if prophylactic anticonvulsants in brain tumour patients (without prior seizures) reduced seizure frequency. We stopped accrual at 100 patients on the basis of the interim analysis. One hundred newly diagnosed brain tumour patients received anticonvulsants (AC Group) or not (No AC Group) in this prospective randomized unblinded study. Sixty patients had metastatic, and 40 had primary brain tumours. Forty-six (46%) patients were randomized to the AC Group and 54 (54%) to the No AC Group. Median follow-up was 5.44 months (range 0.13 -30.1 months). Seizures occurred in 26 (26%) patients, eleven in the AC Group and 15 in the No AC Group. Seizure-free survivals were not different; at three months 87% of the AC Group and 90% of the No AC Group were seizure-free (log rank test, p=0.98). Seventy patients died (unrelated to seizures) and survival rates were equivalent in both groups (median survival = 6.8 months versus 5.6 months, respectively; log rank test, p=0.50). We then terminated accrual at 100 patients because seizure and survival rates were much lower than expected; we would need ≥900 patients to have a suitably powered study. These data should be used by individuals contemplating a clinical trial to determine if prophylactic anticonvulsants are effective in subsets of brain tumour patients (e.g. only anaplastic astrocytomas). When taken together with the results of a similar randomized trial, prophylactic anticonvulsants are unlikely to be effective or useful in brain tumour patients who have not had a seizure. (author)

    2017-08-01

    Full Text Available Purpose: Adherence to international antiemetic prophylaxis guidelines like those of ASCO can result in better control of chemotherapy-induced nausea and vomiting; however, the extent of implementation of such guidelines in India is unknown. Therefore, this survey was planned. Methods: This study was an anonymized cross-sectional survey approved by the ethics committee. Survey items were generated from the clinical questions given in the ASCO guidelines. The survey was disseminated through personal contacts at an oncology conference and via e-mail to various community oncology centers across India. The B1, B2, and B3 domains included questions regarding the optimal antiemetic prophylaxis for high, moderate, and low-minimal emetogenic regimens. Results: Sixty-six (62.9% of 105 responded and 65 centers (98.5% were aware of the published guidelines. The partial, full, and no implementation scores were 92.5%, 4.5%, and 3.0%, respectively. Full implementation was better for the low-minimal emetogenic regimens (34.8% than the highly emetogenic regimens (6.1%. The three most frequent reasons for hampered implementation of ASCO guidelines in routine chemotherapy practice cited by centers were a lack of sensitization (26 centers; 39.4%, lack of national guidelines (12 centers; 18.2%, and lack of administrative support (10 centers; 15.2%. Conclusion: Awareness regarding ASCO antiemetic guidelines is satisfactory in Indian oncology practices; however, there is a need for sensitization of oncologists toward complete implementation of these guidelines in their clinical practice.

    Full Text Available BACKGROUND: Oxytocin (10 IU is the drug of choice for prevention of postpartum hemorrhage (PPH. Its use has generally been restricted to medically trained staff in health facilities. We assessed the effectiveness, safety, and feasibility of PPH prevention using oxytocin injected by peripheral health care providers without midwifery skills at home births. METHODS AND FINDINGS: This community-based, cluster-randomized trial was conducted in four rural districts in Ghana. We randomly allocated 54 community health officers (stratified on district and catchment area distance to a health facility: ≥10 km versus <10 km to intervention (one injection of oxytocin [10 IU] one minute after birth and control (no provision of prophylactic oxytocin arms. Births attended by a community health officer constituted a cluster. Our primary outcome was PPH, using multiple definitions; (PPH-1 blood loss ≥500 mL; (PPH-2 PPH-1 plus women who received early treatment for PPH; and (PPH-3 PPH-2 plus any other women referred to hospital for postpartum bleeding. Unsafe practice is defined as oxytocin use before delivery of the baby. We enrolled 689 and 897 women, respectively, into oxytocin and control arms of the trial from April 2011 to November 2012. In oxytocin and control arms, respectively, PPH-1 rates were 2.6% versus 5.5% (RR: 0.49; 95% CI: 0.27-0.88; PPH-2 rates were 3.8% versus 10.8% (RR: 0.35; 95% CI: 0.18-0.63, and PPH-3 rates were similar to those of PPH-2. Compared to women in control clusters, those in the intervention clusters lost 45.1 mL (17.7-72.6 less blood. There were no cases of oxytocin use before delivery of the baby and no major adverse events requiring notification of the institutional review boards. Limitations include an unblinded trial and imbalanced numbers of participants, favoring controls. CONCLUSION: Maternal health care planners can consider adapting this model to extend the use of oxytocin into peripheral settings including, in some

    Full Text Available BackgroundIncreasingly, prophylactic mastectomy has been evaluated as a treatment of breast cancer. Hereditary breast cancer now accounts for approximately 5%–10% of all cases of breast cancer, meaning that the widespread implementation of prophylactic mastectomy may significantly reduce the occurrence of breast cancer. However, prophylactic mastectomy is rarely performed in Korea. Therefore, in this study, we assessed Koreans' attitudes toward and awareness of preventive mastectomy.MethodsThis was a prospective study of a cohort of patients attending outpatient clinics and their relatives. Data were collected using self-administered questionnaires assessing sex, age, educational level, knowledge of breast cancer, understanding of prophylactic mastectomy, attitudes toward prophylactic mastectomy, and reasons for choosing prophylactic mastectomy.ResultsSixty-five patients were included. Most patients (36.9% were between 40 and 49 years of age and 58.4% were college graduates. Only six respondents (9% understood prophylactic mastectomy, and 17 respondents (27% stated that they would agree to undergo prophylactic mastectomy if necessary. Reasons given for refusing prophylactic mastectomy included aesthetic concerns (38%, the perception that it would not cure the disease (26%, possible surgical complications (24%, and financial cost (6%.ConclusionsIn this study, most of the respondents showed a poor knowledge of prophylactic mastectomy. Ultimately, it will be necessary to establish medical guidelines for patients with a high risk of breast cancer, with the objective of providing accurate information and proper treatment at hospitals.

    Hepatitis E has been increasingly recognized as an underestimated global disease burden in recent years. Subpopulations with more serious infection-associated damage or death include pregnant women, patients with basic liver diseases, and elderly persons. Vaccine would be the most effective means for prevention of HEV infection. The lack of an efficient cell culture system for HEV makes the development of classic inactive or attenuated vaccine infeasible. Hence, the recombinant vaccine approaches are explored deeply. The neutralizing sites are located almost exclusively in the capsid protein, pORF2, of the virion. Based on pORF2, many vaccine candidates showed potential of protecting primate animals; two of them were tested in human and evidenced to be well tolerated in adults and highly efficacious in preventing hepatitis E. The world's first hepatitis E vaccine, Hecolin ® (HEV 239 vaccine), was licensed in China and launched in 2012.

    To determine the acute corn-specific serum IgE and IgG, total serum IgE, and clinical responses to s.c. administration of prophylactic vaccines and aluminum adjuvant in corn-allergic dogs. 20 allergic and 8 nonallergic dogs. 17 corn-allergic dogs were vaccinated. Eight clinically normal dogs also were vaccinated as a control group. Serum corn-specific IgE, corn-specific IgG, and total IgE concentrations were measured in each dog before vaccination and 1 and 3 weeks after vaccination by use of an ELISA. The corn-allergic dogs also had serum immunoglobulin concentrations measured at 8 and 9 weeks after vaccination. Twenty allergic dogs received a s.c. injection of aluminum adjuvant, and serum immunoglobulin concentrations were measured in each dog 1, 2, 3, 4, and 8 weeks after injection. The allergic dogs were examined during the 8 weeks after aluminum administration for clinical signs of allergic disease. The allergic dogs had significant increases in serum corn-specific IgE and IgG concentrations 1 and 3 weeks after vaccination but not 8 or 9 weeks after vaccination. Control dogs did not have a significant change in serum immunoglobulin concentrations after vaccination. After injection of aluminum adjuvant, the allergic dogs did not have a significant change in serum immunoglobulin concentrations or clinical signs. Allergen-specific IgE and IgG concentrations increase after prophylactic vaccination in allergic dogs but not in clinically normal dogs. Prophylactic vaccination of dogs with food allergies may affect results of serologic allergen-specific immunoglobulin testing performed within 8 weeks after vaccination.

    To evaluate the effectiveness of ondansetron for the prevention of nausea and vomiting from dimethylsulfoxide (DMSO) during autologous stem cell transplantation (ASCT) infusion. Nonrandomized cohort using historical control. Comprehensive cancer center outpatient infusion department. 50 patients receiving ASCT in the outpatient setting. Patients were assessed for nausea and vomiting on their infusion day using the Multinational Association of Supportive Care in Cancer Antiemesis Tool (MAT) at arrival, pre-ASCT infusion, pre-ondansetron administration, prior to the first bag, and after each bag of stem cells. A standard script was used to ensure consistency. Ondansetron, 16 mg IV, was administered 30-90 minutes prior to each ASCT infusion. Number and volume of stem cells bags, as well as infusion rate and emesis episodes, were recorded. Nausea scores and vomiting episodes were compared to historical data. Subjectivity of nausea, potential Hawthorne Effect. Forty-five percent of patients had an MAT score greater than 2 on arrival, decreasing to 18% after receiving ondansetron before the first bag. Twenty-four percent had MAT increases of more than two points by infusion end compared to 58% in the historic control group. Eighteen percent of patients vomited compared to 28% of historic controls. The administration of 16 mg of IV ondansetron significantly reduced DMSO-related nausea and episodes of vomiting in patients receiving ASCT. Prophylactic administration of ondansetron had a positive effect on reducing nausea symptoms and episodes of vomiting during ASCT infusions. These results prompted a change in clinical practice. More research is required to determine whether the inclusion of other antiemetic agents would provide even greater benefit. To date, no other published studies have explored the benefits of premedicating patients with ondansetron prior to ASCT infusions. This study is the first to establish efficacy of ondansetron for an unlabeled indication. These

    The spread of infectious diseases can be impacted by human behavior, and behavioral decisions often depend implicitly on a planning horizon-the time in the future over which options are weighed. We investigate the effects of planning horizons on epidemic dynamics. We developed an epidemiological agent-based model (along with an ODE analog) to explore the decision-making of self-interested individuals on adopting prophylactic behavior. The decision-making process incorporates prophylaxis efficacy and disease prevalence with the individuals' payoffs and planning horizon. Our results show that for short and long planning horizons individuals do not consider engaging in prophylactic behavior. In contrast, individuals adopt prophylactic behavior when considering intermediate planning horizons. Such adoption, however, is not always monotonically associated with the prevalence of the disease, depending on the perceived protection efficacy and the disease parameters. Adoption of prophylactic behavior reduces the epidemic peak size while prolonging the epidemic and potentially generates secondary waves of infection. These effects can be made stronger by increasing the behavioral decision frequency or distorting an individual's perceived risk of infection.

  16. Prophylactic iodine treatment in radiation protection

    Prophylactic iodine treatment is to prevent accumulation of radioactive iodine in the thyroid. This is done by administering a large amount of stable iodine before uptake of radioactive iodine so that further accummulation of iodine in the thyroid will be impossible. This blocking effect should be as complete as possible. This is achieved by administering an initial dose of 200 mg potassium iodide. As the release of radioactive iodine may last several hours or even days; for this reason, maintenance doses of 100 mg potassium iodide should be administered in 8-hour intervals. The risk of prophylactiv iodine treatment is rather low; however, provocation of latent hyperthyreoses must be expected in, at the most, 0.2% of the exposed population. (orig./MG) [de

    The indications for and results of prophylactic treatment of retinal detachment during a period of five years are reported and compared with the results in the literature. Half of the cases (3 out of 6 eyes) which developed a retinal detachment had been horse-shoe tears combined with a vitreous hemorrhage. For this reason a small buckle operation is recommended in these cases, to prevent further traction. Lattice degeneration should rather be observed than treated, except in special cases: This includes eyes where the fellow eye had a detachment from a lattice degeneration, cases in which one eye is blind from an uncured detachment or has no useful visual acuity, and eyes whose fellow eye has giant tears. In aphakic eyes treatment of lattice degeneration is recommended, because the incidence of detachment from these areas is high, especially in young aphakic cases. In one aphakic eye which had been photocoagulated several times the formation of a preretinal membrane was observed.

    Amnioinfusion aims to relieve umbilical cord compression during labour by infusing a liquid into the uterine cavity. The objective of this review was to assess the effects of prophylactic amnioinfusion for women in labour with oligohydramnios, but not fetal heart deceleration, compared with therapeutic amnioinfusion only if fetal heart rate decelerations or thick meconium-staining of the liquor occur. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (28 February 2012). Randomised trials comparing prophylactic amnioinfusion in women in labour with oligohydramnios but not fetal heart rate deceleration in labour with therapeutic amnioinfusion. The authors assessed trial quality and extracted data. One randomized trial of 116 women was included. No differences were found in the rate of caesarean section (risk ratio 1.29, 95% confidence interval 0.60 to 2.74). There were no differences in cord arterial pH, oxytocin augmentation, neonatal pneumonia or postpartum endometritis. Prophylactic amnioinfusion was associated with increased intrapartum fever (risk ratio 3.48, 95% confidence interval 1.21 to 10.05). There appears to be no advantage of prophylactic amnioinfusion over therapeutic amnioinfusion carried out only when fetal heart rate decelerations or thick meconium-staining of the liquor occur.

    Clebopride, a new benzamide derivative, has, in common with the other members of this group, antidopaminergic activity. In animals, its therapeutic ratio is superior to that of metoclopramide at doses free of side effects associated with hyperprolactinemia and extrapyramidal symptoms. The present study was designed to define the maximum tolerated dose (MTD) in patients with advanced histologically-proven cancer, treated with cisplatin at a dose of greater than 50 mg/m2. Most of them were pretreated and refractory to standard antiemetics. Clebopride was started at a dosage of 0.10 mg/kg in a group of 6 patients and escalated by 0.2 mg at each dose level. A total of 30 patients were included. Side effects include somnolence, diarrhea and extrapyramidal-like symptoms. The latter occurred at almost all dose levels in 14% of the cycles and limited continuation of the study. Activity in this group of patients was encouraging but, considering the rate of extrapyramidal symptoms, further dose escalation is not indicated and activity at lower, nontoxic levels should be investigated.

    Nausea and vomiting are the most often observed symptoms in the course of the early radiation syndrome. Their prevention has long been difficult because of the low effectiveness and side-effects of most antiemetics. There is a clear evidence that 5HT 3 receptor antagonists such as ondansetron and granisetron are highly effective to prevent radiation-induced emesis without any side-effect. We studied the prophylactic effectiveness of their oral administration to macacus cynomolgus, for mixed neutron-gamma whole-body exposure, tat high dose rates. Doses of 4 mg of ondansetron or 1 mg of granisetron were administered before, or after, or both before and after irradiation. The treatment was effective when administered both before and after radiation exposure. It was significant but incomplete if administered once. Post-irradiation administration is interesting, particularly in case of accident. Both antiemetic drugs were well tolerated. Their effectiveness and tolerance are apparently comparable. The 5HT 3 receptor antagonists represent a much improved treatment for radiation-induced nausea and vomiting by completely inhibiting emesis, if administered before and after irradiation. Unwanted sedation and extra-pyramidal side-effects, usually associated with the clinical use of D 2 receptor antagonists, were not observed. (authors). 40 refs., 5 tabs

    A systematic review on the cost effectiveness of prophylactic treatments of non-steroidal anti-inflammatory drug (NSAID) induced gastropathy in patients with osteoarthritis or rheumatoid arthritis was conducted. Two reviewers conducted the literature search and the review. Both full and partial economic evaluations published in English, Dutch, or German were included. The criteria list published in the textbook of Drummond was used to determine the quality of the economic evaluations. The methodological quality of three randomised controlled trials (RCTs) in which the economic evaluations obtained probability estimates of NSAID induced gastropathy and adverse events was assessed by a list of internal validity criteria. The conclusions were based on a rating system consisting of four levels of evidence. Ten economic evaluations were included; three were based on RCTs. All evaluations studied misoprostol as prophylactic treatment: in one evaluation misoprostol was studied as a fixed component in a combination with diclofenac (Arthrotec). All economic evaluations comprised analytical studies containing a decision tree. The three trials were of high methodological quality. Nine economic evaluations were considered high quality and one economic evaluation was considered of low methodological quality. There is strong evidence (level "A") that the use of misoprostol for the prevention of NSAID induced gastropathy is cost effective, and limited evidence (level "C") that the use of Arthrotec is cost effective. Although the levels of evidence used in this review are arbitrary, it is believed that a qualitative analysis is useful: quantitative analyses in this field are hampered by the heterogeneity of economic evaluations. Existing criteria to evaluate the methodological quality of economic evaluations may need refinement for use in systematic reviews.

    Hyperoxic ventilation, used to prevent hypoxia during potential periods of hypoventilation, has been reported to paradoxically decrease whole-body oxygen consumption (VO2). Reduction in nutritive blood flow due to oxygen radical production is one possible mechanism. We investigated whether pretreatment with the sulfhydryl group donor and O2 radical scavenger N-acetylcysteine (NAC) would preserve VO2 and other clinical indicators of tissue oxygenation in cardiac risk patients. Thirty patients, requiring hemodynamic monitoring (radial and pulmonary artery catheters) because of cardiac risk factors, were included in this randomized investigation. All patients exhibited stable clinical conditions (hemodynamics, body temperature, hemoglobin, F1O2 depression ( > 0.2 mV) was significantly less marked in the NAC group (NAC: -0.02 +/- 0.17 vs placebo: -0.23 +/- 0.15; P depression if patients were prophylactically treated with NAC. This suggests that pretreatment with NAC could be considered to attenuate impaired tissue oxygenation and to preserve myocardial performance better in cardiac risk patients during hyperoxia.

    Background and purpose: To report recommendations given in the Multinational Association of Supportive Care in Cancer (MASCC) International Consensus Conference regarding the use of antiemetics in radiotherapy. Patients and methods: A steering committee under MASCC auspice chose panel participants for the guidelines development process on prevention of chemotherapy- and radiotherapy-induced emesis (RIE). Pertinent information from published literature as of March 2004 was reviewed for the guideline process. Both the MASCC level of scientific confidence and level of consensus, and the American Society of Clinical Oncology (ASCO) type of evidence and grade for recommendation were adopted. Results: Total body irradiation is classified at high risk, upper abdomen at moderate, lower thorax, pelvis, cranium (radiosurgery) and craniospinal at low, head and neck, extremities, cranium and breast at minimal risk. The recommendations for the use of antiemetics in radiotherapy are as follows: prophylaxis with a 5-HT3 antagonist in patients at high and moderate risk levels of RIE (±dexamethasone in the former group), prophylaxis or rescue with a 5-HT3 antagonist in the low risk group, and rescue with dopamine or a 5-HT3 receptor antagonist in minimal risk level. Conclusions: These recommendations represent a valid tool for prophylaxis and treatment of RIE in clinical practice

    Regorafenib is an oral multikinase inhibitor with a proven survival benefit for metastatic colorectal cancer patients. The KSCC1402/HGCSG1402 study investigated the prophylactic effect of oral dexamethasone (DEX) on regorafenib-related fatigue and/or malaise. Patients who progressed after standard chemotherapy were randomized 1: 1 to a DEX group (2 mg/day; days 1-28) with regorafenib or a placebo group with regorafenib. The primary endpoint was the incidence of fatigue and/or malaise, based on version 4.0 of the National Cancer Institute's CTCAE (Common Terminology Criteria for Adverse Events). One of the secondary endpoints was the in-cidence of fatigue and/or malaise based on the CTCAE assessed by patient-reported outcome (PRO). The incidence of any grade of fatigue and/or malaise assessed by the investigators was 58.8% in the DEX group and 61.1% in the placebo group (p = 0.8101), and that assessed by PRO was 47.2 and 58.3%, respectively (p = 0.3450). The incidence of grade ≥2 fatigue and/or malaise, as assessed by the investigators, was 19.4% for the DEX group and 38.9% for the placebo group (p = 0.0695), and that assessed by PRO was 27.8 and 52.8%, respectively (p = 0.0306). Our results suggest that prophylactic oral DEX is clinically effective in improving regorafenib-related fatigue and/or malaise. © 2018 S. Karger AG, Basel.

  9. Effect of prophylactic treatments on the superficial roughness of dental tissues and of two esthetic restorative materials Efeito de tratamentos profiláticos na rugosidade superficial de tecidos dentais e de dois materiais restauradores estéticos

    Full Text Available Dental prophylaxis is a common way to remove dental plaque and stain, both undesirable factors in most dentistry procedures. However, besides cleaning the tooth surface, prophylactic techniques may increase the surface roughness of restorations and dental tissues, which, in turn, may result in plaque accumulation, superficial staining and superficial degradation. This study evaluated the effect of three prophylactic techniques - sodium bicarbonate jet, pumice paste and whiting paste - on the superficial roughness of two restorative materials - a composite resin and a compomer - and on the superficial roughness of two dental surfaces - enamel and cementum/dentin - through rugosimetric and scanning electron microscopy (SEM analysis. Statistical analysis of the rugosimetric data showed that the use of pumice paste on enamel produced a significantly smoother surface than the natural surface. However, comparing the effect of the three techniques, prophylaxis with the pumice paste produced a rougher surface than did the other techniques as regards enamel and cementum/dentin probably due to its abrasiveness. On composite resin, the pumice paste only produced a rougher surface than did the whiting paste. On compomer, all of the applied treatments produced similar results. Based on rugosimetric and SEM analysis, we could conclude that the prophylactic treatments employed did not improve roughness of the studied surfaces. As to the effects of the techniques, they were different depending on the surfaces on which the prophylactic treatments were applied.A profilaxia dental é uma prática comum para a remoção de placa bacteriana e outros indutos que dificultam a realização dos procedimentos restauradores. Entretanto, como efeito secundário à limpeza, pode-se ter uma superfície mais rugosa e sujeita a manchamentos e degradações.

    1996-01-01

    To analyse if prophylactic cranial irradiation is small cell lung cancer for improved survival is indicated; if adjuvant irradiation could cure the microscopic disease; if and how late effects could be minimized. Data from randomized trials and retrospective studies are critically analysed related to the incidence of central nervous system (CNS) metastases in limited disease patients in complete remission with or without prophylactic cranial irradiation. The mechanisms of late effects on CNS of prophylactic cranial irradiation and combined treatment are presented. Prophylactic cranial irradiation could decrease the incidence of CNS metastases but could not improve survival. A subgroup of patients (9 to 14%) most likely to benefit from prophylactic cranial irradiation includes patients who are likely to have an isolated CNS failure. The actual used total dose in the range 30 to 40 Gy could only conditionally decrease the CNS failure. Higher total and/or daily doses and combined treatment are related with potentially devastating neurologic and intellectual disabilities. No prospective randomized trial has demonstrated a significant survival advantage for patients treated with prophylactic cranial irradiation. Prophylactic cranial irradiation is capable of reducing the incidence of cerebral metastases and delays CNS failure. A subgroup of patients most likely to benefit from prophylactic cranial irradiation (9 to 14%) includes patients who are likely to have an isolated CNS failure, but this had yet to be demonstrated. The toxicity of treatment is difficult to be influenced. Prophylactic cranial irradiation should not be given concurrently with chemotherapy, a larger interval after chemotherapy is indicated. The total dose should be in the range 30 to 36 Gy and the daily fraction size not larger than 2 Gy. (orig.) [de

    This study aims to evaluate the association of prophylactic antenatal steroids, indomethacin, and phototherapy with extremely preterm infant outcomes in a pragmatic setting. Retrospective study of infants born at <28 weeks gestation and admitted to 26 Canadian Neonatal Network neonatal intensive care units between 2010 and 2012. Mortality, severe neurological injury, retinopathy, necrotizing enterocolitis, bronchopulmonary dysplasia, nosocomial infection, and patent ductus arteriosus ligation rates were compared between infants who received antenatal steroids, prophylactic indomethacin, and/or prophylactic phototherapy and those who did not. Of 3,465 eligible infants, 2,900 (84%) received antenatal steroids, 269 (8%) prophylactic indomethacin, and 403 (12%) prophylactic phototherapy. Associations were observed between antenatal steroids and mortality (adjusted odds ration [aOR] 0.47 [0.33-0.66]) and severe neurological injury (aOR 0.60 [0.46-0.77]), indomethacin and ductus arteriosus ligations (aOR 0.52 [0.31-0.87]), but not severe neurological injury (aOR 1.12 [0.81-1.54]), but phototherapy was not associated with any of the neonatal outcomes despite reductions in bilirubin. Antenatal steroids were associated with reduced mortality and neurological injury, prophylactic indomethacin was not associated with reduction in neurological injury and phototherapy was not associated with any improvement in neonatal outcomes. In a pragmatic setting, outside randomized controlled trials, the effectiveness and safety of prophylactic interventions in extremely preterm neonates vary; ongoing monitoring is warranted.

    Nausea and vomiting are the most often observed symptoms in the course of the early radiation syndrome. Their prevention has long been difficult because of the low effectiveness and side-effects of most antiemetics. There is a clear evidence that 5HT{sub 3} receptor antagonists such as ondansetron and granisetron are highly effective to prevent radiation-induced emesis without any side-effect. We studied the prophylactic effectiveness of their oral administration to macacus cynomolgus, for mixed neutron-gamma whole-body exposure, tat high dose rates. Doses of 4 mg of ondansetron or 1 mg of granisetron were administered before, or after, or both before and after irradiation. The treatment was effective when administered both before and after radiation exposure. It was significant but incomplete if administered once. Post-irradiation administration is interesting, particularly in case of accident. Both antiemetic drugs were well tolerated. Their effectiveness and tolerance are apparently comparable. The 5HT{sub 3} receptor antagonists represent a much improved treatment for radiation-induced nausea and vomiting by completely inhibiting emesis, if administered before and after irradiation. Unwanted sedation and extra-pyramidal side-effects, usually associated with the clinical use of D{sub 2} receptor antagonists, were not observed. (authors). 40 refs., 5 tabs.

    Prophylactic intraoperative ureteral stent placement is performed to decrease operative ureteric injury, though few data are available on the effectiveness of this procedure, and no data are available on its cost. To analyze the cost of prophylactic intraoperative cystoscopic ureteral stents in gynecologic surgery. All cases of prophylactic ureteral stent placement performed in gynecologic surgery during a 1-year period were identified and retrospectively reviewed through the electronic medical records database of Summa Health System. Costs were obtained through the Healthcare Cost Accounting System. The principles of cost-effective analysis were used (ie, explicit and detailed descriptions of costs and cost-effectiveness statistics). Importantly, we evaluated cost and not charges or financial model estimates. In addition, we obtained the contribution margins (ie, the hospital's net profit or loss) for prophylactic ureteral stent placement. Other gynecologic procedures were also analyzed. Among 792 major inpatient gynecologic procedures, 18 cases of prophylactic intraoperative ureteral stents were identified. Median costs were as follows: additional cost of prophylactic intraoperative ureteral stenting, $1580; additional cost of surgical resources, $770; cost of ureteral catheters, $427; cost of surgeons, $383. The contribution margins per case for various gynecologic surgical procedures were as follows: oophorectomy, $2804 profit; abdominal hysterectomy, $2649 profit; laparoscopically assisted vaginal hysterectomy (LAVH), $1760 profit. When intraoperative ureteral stenting was added, the contribution margins changed to the following: oophorectomy, $782 profit; abdominal hysterectomy, $627 profit; LAVH, $262 loss. Overall, the contribution margin profit was decreased by about 85%, from $2400 to $380. Prophylactic intraoperative ureteral stenting in gynecologic surgery decreases a hospital's contribution margin. Because of the expense of this procedure, as well as

    Infection with human papilloma virus (HPV) has been identified as the cause of recurrent papillomatosis and of a subgroup of squamous cell carcinomas of the head and neck. A change in prevalence of these lesions, especially for oropharyngeal carcinoma, can be expected as a consequence of the introduction of prophylactic HPV vaccines for young women, targeting the most frequent high- and low-risk HPV subtypes. Vaccination for the major low-risk HPV types has proven to be highly effective against genital warts and activity against papillomatosis can be expected. The possibilities of prophylactic HPV vaccination as well as new developments and the rationale for therapeutic vaccines are discussed on the basis of the current literature.

    Renal allograft rejection is a complex phenomenon involving both cell-mediated and humoral antibody responses. Most transplant programs have used a combination of therapeutic modalites to combat the immune system in an attempt to prolong both allograft and patient survival. Corticosteroids (methylprednisolone (Solu-Medrol) and prednisone and azathioprine (Imuran) are widely accepted as immunosuppressive drugs; however, both are non-specific and have the disadvantage of compromising the recipients' defense mechanisms. Nevertheless, these drugs have proved to be essential to the success of renal transplantation and they are routinely used while the efficacy of other modalities continues to be evaluated. We could find no reports of a prospective study to evaluate the efficacy of prophylactic irradiation in the complex therapeutic situation of renal transplantation with the only variable being the administration of local graft irradiation. The purpose of this study was to evaluate prophylactic graft irradiation for its effectiveness in preventing graft rejection in conjunction with Imuran and corticosteroids

    Intraoperative vomiting leads to serious respiratory complications that could influence the surgical decision-making process for awake craniotomy. However, the use of antiemetics is still limited in Japan. The aim of this study was to investigate the effect of prophylactically administered single low-dose dexamethasone on the incidence of vomiting during awake craniotomy. The frequency of hyperglycemia was also examined. We conducted a retrospective case review of awake craniotomy for glioma resection between 2012 and 2015. Of the 124 patients, 91 were included in the analysis. Dexamethasone was not used in 43 patients and the 48 remaining patients received an intravenous bolus of 4.95 mg dexamethasone at anesthetic induction. Because of stable operating conditions, no one required conscious sedation throughout functional mapping and tumor resection. Although dexamethasone pretreatment reduced the incidence of intraoperative vomiting (P = 0.027), the number of patients who complained of nausea was comparable (P = 0.969). No adverse events related to vomiting occurred intraoperatively. Baseline blood glucose concentration did not differ between each group (P = 0.143), but the samples withdrawn before emergence (P = 0.018), during the awake period (P awake craniotomy cases. However, as even a small dose of dexamethasone increases the risk for hyperglycemia, antiemetic prophylaxis with dexamethasone should be administered after careful consideration. Monitoring of perioperative blood glucose concentration is also necessary.

  19. A Review of NEPA, a Novel Fixed Antiemetic Combination with the Potential for Enhancing Guideline Adherence and Improving Control of Chemotherapy-Induced Nausea and Vomiting

    Full Text Available Combination antiemetic regimens targeting multiple molecular pathways associated with emesis have become the standard of care for prevention of chemotherapy-induced nausea and vomiting (CINV related to highly and moderately emetogenic chemotherapies. Antiemetic consensus guidelines from several professional societies are widely available and updated regularly as new data emerges. Unfortunately, despite substantial research supporting the notion that guideline conformity improves CINV control, adherence to antiemetic guidelines is unsatisfactory. While studies are needed to identify specific barriers to guideline use and explore measures to enhance adherence, a novel approach has been taken to improve clinician adherence and patient compliance, with the development of a new combination antiemetic. NEPA is an oral fixed combination of a new highly selective NK1 receptor antagonist (RA, netupitant, and the pharmacologically and clinically distinct 5-HT3 RA, palonosetron. This convenient antiemetic combination offers guideline-consistent prophylaxis by targeting two critical pathways associated with CINV in a single oral dose administered only once per cycle. This paper will review and discuss the NEPA data in the context of how this first combination antiemetic may overcome some of the barriers interfering with adherence to antiemetic guidelines, enhance patient compliance, and offer a possible advance in the prevention of CINV for patients.

    We assessed the cost-effectiveness of a risk model-guided (RMG) antiemetic prophylaxis strategy compared with the physician's choice (PC) strategy in patients receiving chemotherapy for early-stage breast cancer. We conducted a cost-utility analysis based on a published randomized controlled trial of 324 patients with early-stage breast cancer undergoing chemotherapy at two Canadian cancer centers. Patients were randomized to receive their antiemetic treatments according to either predefined risk scores or the treating physician's preference. Effectiveness was measured as quality-adjusted life years (QALYs) gained. Cost and utility data were obtained from the Canadian published literature. We used generalized estimating equations to estimate the incremental cost-effectiveness ratios (ICERs) and 95% confidence intervals (CIs) over a range of willingness-to-pay values. The lower and upper bounds of the 95% CIs were used to characterize the statistical uncertainty for the cost-effectiveness estimates and construct cost-effectiveness acceptability curves. From the health care system's perspective, the RMG strategy was associated with greater QALYs gained (0.0016, 95% CI 0.0009, 0.0022) and higher cost ($49.19, 95% CI $24.87, $73.08) than the PC strategy, resulting in an ICER of $30,864.28 (95% CI $14,718.98, $62,789.04). At the commonly used threshold of $50,000/QALY, the probability that RMG prophylaxis is cost-effective was >94%; this probability increased with greater willingness-to-pay values. The risk-guided antiemetic prophylaxis is an economically attractive option for patients receiving chemotherapy for early-stage breast cancer. This information supports the implementation of risk prediction models to guide chemotherapy-induced nausea and vomiting prophylaxis in clinical practices.

    Radio frequency wave (RFW) generated by base transceiver station (BTS) has been reported to make deleterious effects on reproduction, possibly through oxidative stress. This study was conducted to evaluate the effect of RFW generated by BTS on oxidative stress in testis and the prophylactic effect of vitamin C by measuring the antioxidant enzymes activity, including glutathione peroxidase, superoxide dismutase (SOD) and catalase, and malondialdehyde (MDA). Thirty-two adult male Sprague-Dawley rats were randomly divided into four experimental groups and treated daily for 45 days as follows: sham, sham+vitamin C (l-ascorbic acid 200 mg/kg of body weight/day by gavage), RFW (exposed to 900 MHz RFW) 'sham' and 'RFW' animals were given the vehicle, i.e., distilled water and the RFW+vitamin C group (received vitamin C in addition to exposure to RFW). At the end of the experiment, all the rats were sacrificed and their testes were removed and used for measurement of antioxidant enzymes and MDA activity. The results indicate that exposure to RFW in the test group decreased antioxidant enzymes activity and increased MDA compared with the control groups (p < 0.05). In the treated group, vitamin C improved antioxidant enzymes activity and reduced MDA compared with the test group (p < 0.05). It can be concluded that RFW causes oxidative stress in testis and vitamin C improves the antioxidant enzymes activity and decreases MDA.

    2013-04-30

    This is an updated version of the original Cochrane review published in Issue 11, 2010 (Derry 2010). Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting, which are commonly associated with migraine. To determine the efficacy and tolerability of paracetamol (acetaminophen), alone or in combination with an antiemetic, compared with placebo and other active interventions in the treatment of acute migraine in adults. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 4 October 2010 for the original review, and to 13 February 2013 for the update. Two clinical trials registers (ClinicalTrials.gov and gsk-clinicalstudyregister.com) were also searched on both occasions. We included randomised, double-blind, placebo- or active-controlled studies using self-administered paracetamol to treat a migraine headache episode, with at least 10 participants per treatment arm. Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared with placebo or other active treatment. Searches for the update identified one additional study for inclusion. Eleven studies (2942 participants, 5109 attacks) compared paracetamol 1000 mg, alone or in combination with an antiemetic, with placebo or other active comparators, mainly sumatriptan 100 mg. For all efficacy outcomes paracetamol was superior to placebo, with NNTs of 12 (19% response with paracetamol, 10% with placebo), 5.0 (56% response with paracetamol, 36% with placebo) and 5.2 (39% response with paracetamol, 20% with placebo) for 2-hour pain-free and 2- and 1

    Despite significant antiemetic advances, almost 50% of treated cancer patients still experience nausea and vomiting (N&V). The goal of antiemetic therapy--complete prevention of treatment-induced nausea and/or vomiting (TIN+/-V)--remains elusive for several reasons. Potentially, N&V may be part of a symptom cluster where co-occurring symptoms negatively affect antiemetic management. Consequently, we examined TIN+/-V incidence and the impact of nausea, vomiting and symptom cluster(s) containing them, respectively, on patients' quality of life (QoL) and psychological adjustment across treatment. A longitudinal secondary analysis was performed on data from a prospective, observational QoL study involving 200 newly diagnosed cancer patients who underwent combined modality treatment. QoL, psychological adjustment and patient/clinical characteristics were examined at pretreatment, on-treatment (8 weeks) and post-treatment. Overall, 62% of patients experienced TIN+/-V, with TIN (60%) doubling TIV incidence (27 %). Exploratory factor analyses of QoL scores at each treatment time point identified a recurrent gastrointestinal symptom cluster comprising nausea, vomiting and appetite loss. Approximately two thirds of patients reported co-occurrence of all three symptoms, which exerted synergistic effects of multiplicative proportions on overall QoL. Patients who reported co-occurrence of these symptoms during treatment experienced significantly greater QoL impairment (physical, role and social functioning, fatigue, N&V, appetite loss, overall physical health, overall QOL) and psychological distress (cancer distress, premorbid neuroticism) than those unaffected (0.001 > p ≤ 0.05). Moreover, nausea was more pervasive than vomiting or appetite loss across treatment and had a greater impact on overall QoL. While antiemetic therapy was effective for vomiting and helped prevent/relieve associated appetite loss, the benefits for appetite loss were seemingly constrained by its

    Full Text Available The Transdermal Drug Delivery System (TDDS is one of the novel routes for systemic delivery of drugs through intact skin. A transdermal patch (TP is a medicated patch that is placed on skin for delivery of medication through skin into the blood stream. The aim of present study was to formulate and evaluate a Unani transdermal patch that could be used for antiemetic therapy. The incorporation of Unani ingredients, namely, Khardal (Brassica nigra, Zanjabeel (Zingiber officinale, Podina (Mentha arvensis, and Sirka (Vinegar were envisaged. The TP was prepared by solvent evaporation technique and was evaluated for organoleptic characteristics and other physicochemical properties, such as thickness, weight uniformity, folding endurance, moisture content, drug content, and tolerability and acceptability of patch. The in vitro permeation study of the patch was carried out through Franz diffusion cell using egg shell membrane as barrier membrane. Phosphate buffer pH 7.4 was used as dissolution medium and the temperature was maintained at 37 ± 1°C. The in vitro permeation study of the prepared TP indicated a time dependent increase in drug release throughout the study. The percentage of cumulative drug release was found to be 77.38% in 24 hours. The study shows a new approach to work in Unani pharmaceutics.

    Maternity care providers administer oxytocin prophylactically to prevent postpartum hemorrhage (PPH). Prophylactic oxytocin is generally considered effective and safe and is promoted by national organizations for standardized use. In this article, the evidence supporting prophylactic oxytocin administration for women undergoing spontaneous labor and birth compared with women whose labors included administration of exogenous oxytocin for induction or augmentation is explored. Using data from randomized controlled trials included in 2 recent Cochrane meta-analyses papers, only studies with women in spontaneous labor were selected for inclusion (N = 4 studies). Outcomes of immediate postpartum bleeding volumes (≥ 500 mL or 1000 mL), risk for blood transfusion, and risk for administration of more uterotonic medication were pooled from these 4 studies. Focused random effects meta-analytics were used. Compared to women without prophylactic oxytocin, women who received prophylactic oxytocin had a lower risk of having a 500 mL or higher blood loss. However, prophylactic oxytocin did not lower risk of PPH (≥ 1000 mL), blood transfusion, or need for additional uterotonic treatment. Prophylactic oxytocin may not confer the same benefits to women undergoing spontaneous labor and birth compared to women laboring with oxytocin infusion. Reasons for this difference are explored from a pharmacologic perspective. In addition, the value of prophylactic oxytocin given recent changes in the definition of PPH from greater than or equal to 500 mL to 1000 mL or more after birth is discussed. Finally, gaps in research on adverse effects of prophylactic oxytocin are presented. More research is needed on reducing risk of PPH for women in spontaneous labor. © 2017 by the American College of Nurse-Midwives.

    2003-09-12

    The lifetime probability of death from gastric dilation-volvulus (GDV) for five dog breeds was estimated based on published breed-specific longevity and GDV incidence. These breeds were Great Dane, Irish Setter, Rottweiler, Standard Poodle and Weimaraner. Lifetime risk (95% CI) of GDV in these breeds ranged from 3.9% (0-11.2%) for Rottweiler to 36.7% (25.2-44.6%) for Great Dane. A decision-tree analysis for prophylactic gastropexy--using lifetime probability of death from GDV and expected cost savings for veterinary services as outcome measures--was undertaken to determine the preferred course of action in several dog breeds. Prophylactic gastropexy was the preferred choice of action for all breeds examined, with the reduction in mortality (versus no gastropexy) ranging from 2.2-fold (Rottweiler) to 29.6-fold (Great Dane). Assuming a prophylactic gastropexy costs US$ 400, the procedure was cost-effective when the lifetime risk of GDV was > or = 34%. The maximum and minimum estimated breakeven costs for the gastopexy procedure ranged from US$ 20 (Rottweiler) to US$ 435 (Great Dane). The cost-effectiveness of prophylactic gastropexy was most sensitive to the cost of treating GDV (US$ 1500). Prophylactic gastropexy raises ethical issues that need to be considered by veterinarians and dog breeders.

    2017-08-01

    Long-term prophylaxis is needed in many patients with hereditary angioedema and poses many challenges. Attenuated androgens are effective in many but are limited by side effect profiles. There is less evidence for efficacy of tranexamic acid and progestagens; however, the small side effect profile makes tranexamic acid an option for prophylaxis in children and progestagens an option for women. C1 inhibitor is beneficial, but at present requires intravenous delivery and may need dose titration for maximum efficacy. Short-term prophylaxis should be considered for all procedures. New therapies are promising in overcoming many problems encountered with current options for long-term prophylaxis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Vaccines containing synthetic peptides derived from tumor-associated antigens (TAA) can elicit potent cytotoxic T lymphocyte (CTL) response if they are formulated in an optimal vaccine delivery system. The aim of this study was to develop a simple and effective lipid-based vaccine delivery system using P5 HER2/neu-derived peptide conjugated to Maleimide-PEG2000-DSPE. The conjugated lipid was then incorporated into liposomes composed of DMPC:DMPG:Chol:DOPE containing Monophosphoryl lipid A (MPL) (Lip-DOPE-P5-MPL). Different liposome formulations were prepared and characterized for their physicochemical properties. To evaluate anti-tumoral efficacy, BALB/c mice were immunized subcutaneously 3 times in two-week intervals and the generated immune response was studied. The results demonstrated that Lip-DOPE-P5-MPL induced a significantly higher IFN-γ production by CD8+ T cells intracellularly which represents higher CTL response in comparison with other control formulations. CTL response induced by this formulation caused the lowest tumor size and the longest survival time in a mice model of TUBO tumor. The encouraging results achieved by Lip-DOPE-P5-MPL formulation could make it a promising candidate in developing effective vaccines against Her2 positive breast cancers.

    To evaluate the safety and efficacy of prophylactic uterine artery embolization (UAE) before obstetrical procedures with high risk for massive bleeding. A retrospective review of 29 female patients who underwent prophylactic UAE from June 2009 to February 2014 was performed. Indications for prophylactic UAE were as follows: dilatation and curettage (D and C) associated with ectopic pregnancy (cesarean scar pregnancy, n = 9; cervical pregnancy, n = 6), termination of pregnancy with abnormal placentation (placenta previa, n = 8), D and C for retained placenta with vascularity (n = 5), and D and C for suspected gestational trophoblastic disease (n = 1). Their medical records were reviewed to evaluate the safety and efficacy of UAE. All women received successful bilateral prophylactic UAE followed by D and C with preservation of the uterus. In all patients, UAE followed by obstetrical procedure prevented significant vaginal bleeding on gynecologic examination. There was no major complication related to UAE. Vaginal spotting continued for 3 months in three cases. Although oligomenorrhea continued for six months in one patient, normal menstruation resumed in all patients afterwards. During follow-up, four had subsequent successful natural pregnancies. Spontaneous abortion occurred in one of them during the first trimester. Prophylactic UAE before an obstetrical procedure in patients with high risk of bleeding or symptomatic bleeding may be a safe and effective way to manage or prevent serious bleeding, especially for women who wish to preserve their fertility

    Infections are the most common cause of morbidity and mortality in pediatric immunocompromised children. The emergence of pan-drug resistant bacteria is particularly concerning for these patients. The risk of infection can be reduced by educational rules, immunizing these patients and sometimes antibiotic prophylaxis. But the individual level of risk is very difficult to assess. Using antibiotics may lead to adverse effects such as allergic reactions, cross-reactions with other drugs, development of super-infections, pseudomembranous colitis and overall development of antibioticresistant bacterial strains. Recommendations for preventing infections in these patients exist for specific case such as inherited disorder or stem cell transplantation. In others cases it depends on physicians' habits: the increase of bacterial resistance could lead to reduce the prescriptions non evidence based and not included in official guidelines. Pneumococcal and meningococcal vaccinations might change guidelines and habits. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available Aim. The aim of the study was to assess the impact of the long-term use of the composite probiotics in patients after restorative proctocolectomy. Method. Forty-three patients (20 females and 23 males, aged 21 to 68 years after restorative proctocolectomy were included in the study. After randomization patients were divided into placebo group and treatment group with oral intake of probiotic containing Lactobacillus acidophilus, Lactobacillus delbrueckii subsp. bulgaricus, and Bifidobacterium bifidus. Patients were investigated during initial visit and during final visit after 9 months. All patients were subjected to standard clinical and endoscopic examination with microscopic study of the specimens. Concentrations of calprotectin and pyruvate kinase isoenzyme M2-PK were determined in all cases. Results. The average severity of pouchitis and the number of patients with pouchitis significantly decrease after 9 months of the probiotic taking. The concentrations of calprotectin and pyruvate kinase isoenzyme M2-PK significantly decreased after the therapy. Conclusions. Nine months of the probiotic treatment (Lactobacillus acidophilus, Lactobacillus delbrueckii subsp. bulgaricus, and Bifidobacterium bifidus reduced the number of patients with pouchitis, decreased the PDAI score, and also decreased the fecal pyruvate kinase and calprotectin. The long-term probiotics use is safe and well accepted and can be an effective method of the pouchitis prevention.

    The protective effect of L-carnitine or Co enzyme Q 10 (Co Q 10) against high magnetic field (20 mt) induced testicular toxicity in mice was evaluated. Animals were injected with L-carnitine (200 mg/kg i.p.) or Co Q 10(200 mg/kg per o.s.) 1 hr before exposure to fractionated doses (1/2 h/day, 3 times per week for 2 weeks) or acute dose (3 hr) of magnetic field. Total sperm count motility, daily sperm production and testicular LDH-X activity as well as histopathological examination were investigated. Exposure of mice to fractionated doses of magnetic field caused a significant decrease in sperm count, motility, daily sperm production and LDH-X activity,which were more pronounced than those of acute dose. Moreover,marked testicular histopathological changes were observed after exposure to fractionated doses of magnetic field. Pretreatment of mice with L-carnitine or Co Q 10 1 hr before exposure to the magnetic field caused a significant recovery of testicular damage induced by high magnetic field (20 mT)

Pressure ulcers have significant impact on emotional and physical wellbeing, quality of life, and health care costs. The use of wound dressings could be an important and cost-effective strategy in preventing pressure ulcers. The main types of dressings that are examined for this purpose in the literature are foam, hydrocolloid, and films. Some small studies have shown a preventative role for sacral dressings with low-shear backings, though they raise concerns about over-hydration of the skin. Further research demonstrates the application of barrier films over bony prominences to have a prophylactic effect; however, adhesive dressings can also contribute to shearing forces on the skin. There is a vast body of research that examines the use of dressings to prevent pressure ulcers; however, there is limited high-level evidence, such as randomized control trials. A 2013 Cochrane review indicated that there is a paucity of high-level evidence to support the prophylactic use of dressings to prevent pressure ulcers; this paper will examine the emerging literature and consider its relevance to pressure ulcer prevention protocols.

    The SMART trial is a UK-based, multicentre RCT comparing prophylactic radiotherapy and symptom-based (deferred) radiotherapy in 203 patients with Malignant Pleural Mesothelioma who had undergone large bore pleural interventions. Using costs and quality of life data collected alongside the clinical trial, we will estimate the cost-effectiveness of prophylactic radiotherapy compared to deferred radiotherapy over a 1-year period. Healthcare utilization and costs were captured during the trial. Utility weights produced by the EQ-5D questionnaire were used to determine quality-adjusted life-years (QALY) gained. The incremental cost-effectiveness ratio was calculated over the one-year trial period. Costs were similar in the immediate and deferred radiotherapy groups: £5480.40 (SD = £7040; n = 102) and £5461.40 (SD = £7770; n = 101) respectively. There was also no difference in QALY: 0.498 (95% CI: [0.45, 0.547]) in the prophylactic radiotherapy group versus 0.525 (95% CI: [0.471, 0.580]) in the deferred group. At a willingness to pay threshold of £30,000/QALY there was only a 24% chance that prophylactic radiotherapy was cost-effective compared to deferred radiotherapy. There was no significant effect of prophylactic radiotherapy on quality of life in the intervention group, nor was there any discernable decrease in healthcare costs. There is little evidence to suggest that prophylactic radiotherapy is a cost-effective intervention in this population. ISRCTN72767336 with ISRCTN.

    Full Text Available Background and Aims: Chemotherapy-induced acute and delayed emesis involves the activation of multiple pathways, with 5-hydroxytryptamine (5-HT; serotonin playing a major role in the initial response. Substance P tachykinin NK1 receptor antagonists can reduce emesis induced by disparate emetic challenges and therefore have a clinical utility as broad inhibitory anti-emetic drugs. In the present studies, we investigate the broad inhibitory anti-emetic profile of a relatively new NK1 receptor antagonist, netupitant, alone or in combination with the long acting 5-HT3 receptor antagonist, palonosetron, for a potential to reduce emesis in ferrets and shrews.Materials and Methods: Ferrets were pretreated with netupitant and/or palonosetron, or their combination, and then administered apomorphine (0.125 mg/kg, s.c., morphine (0.5 mg/kg, s.c., ipecacuanha (1.2 mg/kg, p.o., copper sulphate (100 mg/kg, intragastric, or cisplatin (5-10 mg/kg, i.p.; in other studies netupitant was administered to Suncus murinus before motion (4 cm horizontal displacement, 2 Hz for 10 min.Results: Netupitant (3 mg/kg, p.o. abolished apomorphine-, morphine-, ipecacuanha- and copper sulphate-induced emesis. Lower doses of netupitant (0.03-0.3 mg/kg, p.o. dose-dependently reduced cisplatin (10 mg/kg, i.p.-induced emesis in an acute (8 h model, and motion-induced emesis in Suncus murinus. In a ferret cisplatin (5 mg/kg, i.p.-induced acute and delayed emesis model, netupitant administered once at 3 mg/kg, p.o., abolished the first 24 h response and reduced the 24-72 h response by 94.6 %; the reduction was markedly superior to the effect of a three times per day administration of ondansetron (1 mg/kg, i.p.. A single administration of netupitant (1 mg/kg, p.o. plus palonosetron (0.1 mg/kg, p.o. combined with dexamethasone (1 mg/kg, i.p., once per day, also significantly antagonized cisplatin-induced acute and delayed emesis and was comparable with a once-daily regimen of

    This study was undertaken to investigate the hemodynamic effect of prophylactic digitalization before major surgical procedures. Sixteen patients, all admitted for an elective vascular operation for arteriosclerotic disease and all with impaired left ventricular function, were investigated. In half of the patients, digitalis was given before the operation, the other half of the patients served as the control study. The measured parameters were pulmonary artery mean pressure, pulmonary capillary wedge pressure, central venous pressure, mean arterial blood pressure, heart rate, cardiac output, blood volume and arterial, as well as venous, oxygen content. Preoperatively, before digitalization, no significant differences were noted between the two groups at rest and during exercise. Before anesthesia and postoperatively, those given digitalis had improved cardiac function. Those in both groups, however, had a normal hemodynamic response to the surgical trauma. In this study, a definite answer is not provided concerning the usefulness of prophylactic digitalization but an increase in the ability of the digitalized heart to withstand the imposition of a pressure load postoperatively is suggested.

    Full Text Available Objectives: The aim of this review was to systematically examine the available evidence for the effectiveness of prophylactic antibiotics in cases of vesicoureteric reflux (VUR. Materials and Methods: We searched the relevant data on medical management of VUR and the date of last search was June 2008. The search included both randomized controlled trials as well as the nonrandomized trials and the data sources were; MEDLINE, online peer reviewed journals, Cochrane database and abstracts from conference proceedings. Results: Barring few most of the studies published on medical management were nonrandomized. Besides being small in number many of these studies were of poor-quality and poorly designed eventually failing in giving a reliable answer in this regard. Few of the studies suggest that the children with low grade VUR might do well even without antibiotic prophylaxis. Conclusions : In the absence of properly designed, randomized controlled trials and long-term follow-up the question of antibiotic prophylaxis in cases of VUR remains unanswered in large part of it. Whether to give prophylactic antibiotics or not would ultimately need a shared decision-making involving both the treating physician and the parents assessing both the risks and the benefits.

    The behavior of micellization of chlorpromazine hydrochloride (CPH) as an antiemetic drug and its inclusion complex formation with β-cyclodextrin (β-CD) was studied using conductometric technique. The binding or association constant of the complexation equilibrium is evaluated from conductometric measurements by using a nonlinear regression method. The resulting K values for micellization as well as complexation are analyzed. The experiments were carried out at different temperatures. It has been found that CPH form only the 1:1 complex. The association constant values are used for evaluation of thermodynamic parameters of complexation, such as ΔG complex o , ΔH complex o and ΔS complex o .

    Anterior cruciate ligament (ACL) injury can be a painful, debilitating and costly consequence of participating in sporting activities. Prophylactic knee bracing aims to reduce the number and severity of ACL injury, which commonly occurs during landing maneuvers and is more prevalent in female athletes, but a consensus on the effectiveness of prophylactic knee braces has not been established. The lower-limb muscles are believed to play an important role in stabilizing the knee joint. The purpose of this study was to investigate the changes in lower-limb muscle function with prophylactic knee bracing in male and female athletes during landing. Fifteen recreational athletes performed double-leg drop landing tasks from 0.30m and 0.60m with and without a prophylactic knee brace. Motion analysis data were used to create subject-specific musculoskeletal models in OpenSim. Static optimization was performed to calculate the lower-limb muscle forces. A linear mixed model determined that the hamstrings and vasti muscles produced significantly greater flexion and extension torques, respectively, and greater peak muscle forces with bracing. No differences in the timings of peak muscle forces were observed. These findings suggest that prophylactic knee bracing may help to provide stability to the knee joint by increasing the active stiffness of the hamstrings and vasti muscles later in the landing phase rather than by altering the timing of muscle forces. Further studies are necessary to quantify whether prophylactic knee bracing can reduce the load placed on the ACL during intense dynamic movements. Copyright © 2016 Elsevier Ltd.

    Full Text Available Background: Jaundice is a common clinical condition in newborn occurring in approximately 60% of term and 80% of preterm infants. Unconjugated hyperbilirubinemia is universally common in all preterm infants especially in newborns with very low biLth weight. Low birth weight and premature infants are at major risk for exaggerated hyperbilirubinemia that can lead to bilirubin encephalopathy. Significant heterogeneity in the approach to the treatment of jaundiced neonates exists throughout the world. Phototherapy is the most common treatment for neonatal hyperbilirubinemia and could be most effective in preventing the sequelae of hyperbilirubinemia if initiated prophylactically. This randomized clinical trial has been proposed with the objective of assessing the efficacy of prophylactic photo therapy in preventing significant rise of unconjugated hyperbilirubinemia in premature neonates weighing less than 1500 gram and therefore to decrease the need for exchange transfusion and finally to reduce hospital stay due to hyperbilirubinemia. Methods: This randomized controlled clinical trial enrolled sixty newborns with birth weight less than 1500 gram. They were divided into two groups: 1 Prophylactic group, in whom phototherapy was started within 24 hours of birth and continued for 7 days and 2 Control group in whom therapeutic phototherapy was started considering serum bilirubin level and other clinical condi­tions as per institutional guidelines. Mean value of total serum bilirubin (TSB, duration of phototherapy, the need for exchange transfusion and duration of hospital stay in both groups were analyzed.Results: The maximum mean TSB level in prophylactic group was observed on 7th day and in control group it was observed on 3rd day of life. The total serum bilirubin levels were significantly lower in the 3rd and 5th days of life in the prophylactic group in comparison to control group (P value 0.001. Total serum bilirubin level exceeded therapeutic

    The objective of this study was to estimate the cost of antiemetic therapy for chemotherapy-induced nausea and vomiting (CINV) in daily practice in Japan. This was a retrospective observational study using medical records. Eligible patients were those with bladder or testicular cancer receiving platinum-containing highly emetogenic chemotherapy. The incidence of CINV on days 1-5 in single-day chemotherapy and on days 1-9 in multiple-day chemotherapy, and the costs of antiemetic therapy directly associated with the administration of antiemetics were estimated. The analysis of costs was performed from a hospital perspective. A total of 54 patients or 169 chemotherapy courses were included. In all chemotherapy courses 5-HT(3) receptor antagonists were used on the day(s) that platinum-containing agents were administered and frequently used on subsequent days. In contrast, the use of corticosteroids was infrequent. Acute CINV in single-day chemotherapy was well controlled, but the incidences of delayed CINV in single-day chemotherapy and CINV in multiple-day chemotherapy were relatively high. The costs for antiemetic therapy were $484.65 in courses with CINV and $318.56 in courses without CINV, and the difference was approximately $170 per chemotherapy course, which was considered to be mainly imputable to the prevalence of CINV. The cost of antiemetic therapy for CINV is substantial in Japan as well as in other countries, and it is suggested that the onset of CINV is a possible cost driver. The improvements in antiemetic therapy may contribute not only to improved patient well-being but also to a reduction of economic burden.

    The past decade has seen an increasing prevalence of prophylactic mastectomy with decreasing ages of patients treated for breast cancer. Data are limited on the fiscal impacts of contralateral prophylactic mastectomy trends, and no study has compared bilateral prophylactic mastectomy with reconstruction to surveillance in high-risk patients. Lifetime third-party payer costs over 30 years were estimated with 2013 Medicare reimbursement rates. Costs were estimated for patients choosing contralateral or bilateral prophylactic mastectomy versus surveillance, with immediate reconstructions using a single-stage implant, tissue expander, or perforator-based free flap approach. Published cancer incidence rates predicted the percentage of surveillance patients that would require mastectomies. Sensitivity analyses were conducted that varied cost growth, discount rate, cancer incidence rate, and other variables. Lifetime costs and present values (3 percent discount rate) were estimated. Lifetime prophylactic mastectomy costs were lower than surveillance costs, $1292 to $1993 lower for contralateral prophylactic mastectomy and $15,668 to $21,342 lower for bilateral prophylactic mastectomy, depending on the reconstruction. Present value estimates were slightly higher for contralateral prophylactic mastectomy over contralateral surveillance but still cost saving for bilateral prophylactic mastectomy compared with bilateral surveillance. Present value estimates are also cost saving for contralateral prophylactic mastectomy when the modeled contralateral breast cancer incidence rate is increased to at least 0.6 percent per year. These findings are consistent with contralateral and bilateral prophylactic mastectomy being cost saving in many scenarios, regardless of the reconstructive option chosen. They suggest that physicians and patients should continue to receive flexibility in deciding how best to proceed clinically in each case.

    an exacerbation was reduced (odds ratio (OR) 0.55; 95% confidence interval (CI) 0.39 to 0.77, 3 studies, 1262 participants, high quality). This represented a reduction from 69% of participants in the control group compared to 54% in the treatment group (95% CI 46% to 63%) and the number needed to treat to prevent one exacerbation (NNTb) was therefore 8 (95% CI 5 to 18). The frequency of exacerbations was also reduced with continuous prophylactic antibiotic treatment (rate ratio 0.73; 95% CI 0.58 to 0.91).Use of pulsed antibiotic treatment showed a non-significant reduction in the number of people with exacerbations (OR 0.87; 95% CI 0.69 to 1.09, 1 study, 1149 participants, moderate quality) and the test for interaction showed that this result was significantly different from the effect on exacerbations with continuous antibiotics.There was a statistically significant improvement in quality of life with both continuous and pulsed antibiotic treatment but this was smaller than the four unit improvement that is regarded as being clinically significant (MD -1.78; 95% CI -2.95 to -0.61, 2 studies, 1962 participants, moderate quality).Neither pulsed nor continuous antibiotics showed a significant effect on the secondary outcomes of frequency of hospital admissions, change in lung function, serious adverse events or all-cause mortality (moderate quality evidence).The adverse events that were recorded varied among the trials depending on the different antibiotics used. Azithromycin was associated with a significant hearing loss in the treatment group. The moxifloxacin pulsed study reported a significantly higher number of adverse events in the treatment arm due to the marked increase in gastrointestinal adverse events (P antibiotic resistance in the community is of major concern. One study found newly colonised patients to have higher rates of antibiotic resistance. Patients colonised with moxifloxacin-sensitive pseudomonas at initiation of therapy rapidly became resistant

    Antiemetic agent Meclizine HCl, widely prescribed in vertigo, is available only in immediate release dosage forms. The approved therapeutic dose and shorter elimination half-life make Meclizine HCl a potential candidate to be formulated in extended release dosage form. This study was aimed to develop extended release Meclizine HCl pellets by extrusion spheronization using natural and synthetic lipids. Influence of lipid type, drug/lipid ratio and combinations of different lipids on drug release and sphericity of pellets were evaluated. Thirty two formulations were prepared with four different lipids, Glyceryl monostearate (Geleol ® ), Glyceryl palmitostearate (Precirol ® ), Glyceryl behenate (Compritol ® ) and Carnauba wax, utilized either alone or in combinations of drug/lipid ratio of 1:0.5-1:3. Dissolution studies were performed at variable pH and release kinetics were analyzed. Fourier transform infrared spectroscopy was conducted and no drug lipid interaction was found. Sphericity indicated by shape factor (e R ) varied with type and concentration of lipids: Geleol ® (e R  = 0.891-0.997), Precirol ® (e R  = 0.611-0.743), Compritol ® (e R  = 0.665-0.729) and Carnauba wax (e R  = 0.499-0.551). Highly spherical pellets were obtained with Geleol ® (Aspect ratio = 1.005-1.052) whereas irregularly shaped pellets were formed using Carnauba wax (Aspect ratio = 1.153-1.309). Drug release was effectively controlled by three different combinations of lipids: (i) Geleol ® and Compritol ® , (ii) Geleol ® and Carnauba wax and (iii) Geleol ® , Compritol ® and Carnauba wax. Scanning electron microscopy of Compritol ® pellets showed smooth surface with pores, whereas, irregular rough surface with hollow depressions was observed in Carnauba wax pellets. Energy dispersive spectroscopy indicated elemental composition of lipid matrix pellets. Kinetics of (i) Geleol ® and Compritol ® pellets, explained by Korsmeyer-Peppas (R 2  = 0.978-0.993) indicated

    A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

    The optimal antibiotic prophylaxis for pediatric shunt-related procedures is not clear. There is much inconsistency among different medical centers. This paper summarizes and analyzes the various prophylactic antibiotic regiments used for shunt-related surgeries at different pediatric neurosurgery centers in the world. A survey questionnaire was distributed through the Pediatric Neurosurgery list-server (an e-mail-based special interest group in pediatric neurosurgery). Forty-five completed questionnaires were received, one per medical center, primarily from pediatric neurosurgeons with the following geographic breakdown: 25 from North America, 13 from Europe, and 7 from Asia and other countries. All centers routinely administered prophylactic antibiotics for shunt-related procedures. The drugs of choice were first-generation cephalosporins (23), second-generation cephalosporins (10), naficillin/oxacillin (4), vancomycin (3), clindamycin (1), amoxicillin (1), and mixed protocols in three centers. The initial drug administration ("first dose") was: in the department before transfer to operating room (5), upon arrival to operating room (11), at induction of anesthesia (13), and at initial skin incision (16). The duration of antibiotic dosage also varied: single dose (13), 24-h administration (26), 48-h administration (2), and longer than 48 h in four centers. Two general tendencies were noted, common to the majority of participating centers. There was a general trend to modify antibiotic treatment protocol in "high-risk" populations. The second common theme noted in more than half of responding centers was the use of long-term antibiotic treatment for externalized devices (such as externalized shunts, external ventricular drains or lumbar drains), usually till the device was in place.

    Full Text Available In a prospective, double blind, randomized trial, 120 children, aged 3-8 years,ASAI-II, undergoing strabismus repair were randomly divided into three groups (n = 40 each. Oral clonidine premedication (4gg.kg-1 was administered to all the patients two hours prior to surgery. Soon after induction of anaesthesia, Group G patients were administered intravenous granisetron (40gg.kg-1 , Group D intravenous dexamethasone (150gg.kg-1 and group S received 4ml normal saline. Postoperatively, children were continuously monitored and assessed half-hourly till discharge and then after 24 hours for vomiting and pain. The overall incidence of postoperative emesis was lower (15.4% in the Group G compared with the Group D (21.6% in the first 24 hours (P>0.05. The Group S had a highest incidence of postoperative vomiting ((37% P value < 0.0324 compared to group G. The frequency of early vomiting was highest in the S group. Both G and D groups showed better control of delayed emetic episodes. We observed that in children who were premedicated with clonidine, both IV granisetron or dexamethasone were efficacious in reducing the incidence and severity of POV in day-care strabismus surgery.

    An alarming increase in emergence of antibiotic resistance among pathogens worldwide has become a serious threat to our ability to treat infectious diseases according to the World Health Organization. Extensive use of antibiotics by livestock producers promotes the spread of new resistant strains, some of zoonotic concern, which increases food-borne illness in humans and causes significant economic burden on healthcare systems. Furthermore, consumer preferences for meat/poultry/fish produced without the use of antibiotics shape today's market demand. So, it is viewed as inevitable by the One Health Initiative that humans need to reduce the use of antibiotics and turn to alternative, improved means to control disease: vaccination and prophylactics. Besides the intense research focused on novel therapeutic molecules, both these strategies rely heavily on the availability of cost-effective, efficient and scalable production platforms which will allow large-volume manufacturing for vaccines, antibodies and other biopharmaceuticals. Within this context, plant-based platforms for production of recombinant therapeutic proteins offer significant advantages over conventional expression systems, including lack of animal pathogens, low production costs, fast turnaround and response times and rapid, nearly-unlimited scalability. Also, because dried leaves and seeds can be stored at room temperature for lengthy periods without loss of recombinant proteins, plant expression systems have the potential to offer lucrative benefits from the development of edible vaccines and prophylactics, as these would not require "cold chain" storage and transportation, and could be administered in mass volumes with minimal processing. Several biotechnology companies currently have developed and adopted plant-based platforms for commercial production of recombinant protein therapeutics. In this manuscript, we outline the challenges in the process of livestock immunization as well as the current

    Background: In recent years, radical breast cancer surgery has been largely replaced by breast conservation treatment, due to early diagnosis and more effective adjuvant treatment. While breast conservation is mostly preferred, the trend of bilateral mastectomy has risen in the United States. The aim of this study is to determine factors influencing patients’ choice for having contralateral prophylactic mastectomy (CPM). Methods: This is a retrospective study of 373 patients diagnosed with primary invasive breast cancer who were treated by bilateral or unilateral mastectomy (BM or UM) at the Revlon/UCLA Breast Center between Jan. 2002 and Dec. 2010. In the BM group, only those with unilateral breast cancer who chose CPM were included in the analysis. Results: When compared with the UM group, the following factors were found to be associated with BM: younger age, pre-menopausal, a family history of breast/ovarian cancer, BRCA mutation, more breast biopsies, history of breast augmentation, having MRI study within 6 months before the surgery, more likely to have reconstruction and sentinel lymph node biopsy (SLNB) and fewer had neoadjuvant/adjuvant chemotherapy/radiation. When patients with bilateral breast cancer were excluded, multivariate logistic regression analysis indicated younger patients with negative nodes, SLNB as the only nodal surgery and positive family history were significant factors predicting CPM and immediate reconstruction using tissue expanders or implants. Conclusion: Younger age, lower TN stage, requiring only SLNB and high risk family history predict contralateral prophylactic mastectomy. Tissue expander/implant-based reconstructions were more frequently chosen by patients with BM. PMID:26097557

    Purpose: To determine the effect of prophylactic gastrostomy tube (GT) placement on acute and long-term outcome for patients treated with definitive chemoradiotherapy for locally advanced head and neck cancer. Methods and Materials: One hundred twenty consecutive patients were treated with chemoradiotherapy for Stage III/IV head and neck cancer to a median dose of 70 Gy (range, 64-74 Gy). The most common primary site was the oropharynx (66 patients). Sixty-seven patients (56%) were treated using intensity-modulated radiotherapy (IMRT). Seventy patients (58%) received prophylactic GT placement at the discretion of the physician before initiation of chemoradiotherapy. Results: Prophylactic GT placement significantly reduced weight loss during radiation therapy from 43 pounds (range, 0 to 76 pounds) to 19 pounds (range, 0 to 51 pounds), which corresponded to a net change of -14% (range, 0% to -30%) and -8% (range, +1% to -22%) from baseline, respectively (p < 0.001). However, the proportion of patients who were GT-dependent at 6- and 12-months after treatment was 41% and 21%, respectively, compared with 8% and 0%, respectively, for those with and without prophylactic GT (p < 0.001). Additionally, prophylactic GT was associated with a significantly higher incidence of late esophageal stricture compared with those who did not have prophylactic GT (30% vs. 6%, p < 0.001). Conclusions: Although prophylactic GT placement was effective at preventing acute weight loss and the need for intravenous hydration, it was also associated with significantly higher rates of late esophageal toxicity. The benefits of this strategy must be balanced with the risks.

    We compare aromatherapy with inhaled isopropyl alcohol versus oral ondansetron for treating nausea among emergency department (ED) patients not requiring immediate intravenous access. In a randomized, blinded, placebo-controlled trial, we enrolled a convenience sample of adults presenting to an urban tertiary care ED with chief complaints including nausea or vomiting. We randomized subjects to 1 of 3 arms: inhaled isopropyl alcohol and 4 mg oral ondansetron, inhaled isopropyl alcohol and oral placebo, and inhaled saline solution placebo and 4 mg oral ondansetron. The primary outcome was mean nausea reduction measured by a 0- to 100-mm visual analog scale from enrollment to 30 minutes postintervention. Secondary outcomes included receipt of rescue antiemetic medications and adverse events. We enrolled 122 subjects, of whom 120 (98.3%) completed the study. Of randomized subjects, 40 received inhaled isopropyl alcohol and oral ondansetron, 41 received inhaled isopropyl alcohol and oral placebo, and 41 received inhaled saline solution placebo and oral ondansetron. The mean decrease in nausea visual analog scale score in each arm was 30 mm (95% confidence interval [CI] 22 to 37 mm), 32 mm (95% CI 25 to 39 mm), and 9 mm (95% CI 5 to 14 mm), respectively. The proportions of subjects who received rescue antiemetic therapy in each arm were 27.5% (95% CI 14.6% to 43.9%), 25.0% (95% CI 12.7% to 41.2%), and 45.0% (95% CI 29.3% to 61.5%), respectively. There were no adverse events. Among ED patients with acute nausea and not requiring immediate intravenous access, aromatherapy with or without oral ondansetron provides greater nausea relief than oral ondansetron alone.

    2013-11-18

    Penetrating abdominal trauma occurs when the peritoneal cavity is breached. Routine laparotomy for penetrating abdominal injuries began in the 1800s, with antibiotics first being used in World War II to combat septic complications associated with these injuries. This practice was marked with a reduction in sepsis-related mortality and morbidity. Whether prophylactic antibiotics are required in the prevention of infective complications following penetrating abdominal trauma is controversial, however, as no randomised placebo controlled trials have been published to date. There has also been debate about the timing of antibiotic prophylaxis. In 1972 Fullen noted a 7% to 11% post-surgical infection rate with pre-operative antibiotics, a 33% to 57% infection rate with intra-operative antibiotic administration and 30% to 70% infection rate with only post-operative antibiotic administration. Current guidelines state there is sufficient class I evidence to support the use of a single pre-operative broad spectrum antibiotic dose, with aerobic and anaerobic cover, and continuation (up to 24 hours) only in the event of a hollow viscus perforation found at exploratory laparotomy. To assess the benefits and harms of prophylactic antibiotics administered for penetrating abdominal injuries for the reduction of the incidence of septic complications, such as septicaemia, intra-abdominal abscesses and wound infections. Searches were not restricted by date, language or publication status. We searched the following electronic databases: the Cochrane Injuries Group Specialised Register, CENTRAL (The Cochrane Library 2013, issue 12 of 12), MEDLINE (OvidSP), Embase (OvidSP), ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED), ISI Web of Science: Conference Proceedings Citation Index- Science (CPCI-S) and PubMed.

    The use of modern analytical methods has demonstrated that aluminium salts can be absorbed from the gut and concentrated in various human tissues, including bone, the parathyroids and brain. The neurotoxicity of aluminium has been extensively characterized in rabbits and cats, and high concentrations of aluminium have been detected in the brain tissue of patients with Alzheimer's disease. Various reports have suggested that high aluminium intakes may be harmful to some patients with bone disease or renal impairment. Fatal aluminium-induced neuropathies have been reported in patients on renal dialysis. Since there are no demonstrable consequences of aluminium deprivation, the prophylactic reduction of aluminium intake by many patients would appear prudent. In this report, the major sources of aluminium in foods and non-prescription drugs are summarized and alternative products are described. The most common foods that contain substantial amounts of aluminium-containing additives include some processed cheeses, baking powders, cake mixes, frozen doughs, pancake mixes, self-raising flours and pickled vegetables. The aluminium-containing non-prescription drugs include some antacids, buffered aspirins, antidiarrhoeal products, douches and haemorrhoidal medications. The advisability of recommending a low aluminium diet for geriatric patients is discussed in detail.

    The aim of the study was to work out a prophylactic program for strain urinary incontinence. Analysis of literature on the subject and results of own investigations presented in the first part of the paper indicate that the program of prophylaxis of strain urinary incontinence should primarily include: (1) Preparation of the medical staff (nurses, midwives) for propagating health education among women on prevention of strain urinary incontinence. (2) Preparation of adequate educational materials in the form of brochures, leaflets, information posters about symptoms, causes and prophylaxis of urinary incontinence indicating health care institutions available to all women when the disease is suspected or already present. (3) Propagation of problems connected with strain urinary incontinence in the mass media providing information to a wide audience in order to make people realize the significance of this social problem and break stereotypes associated with this disease of "shame". (4) Preparation of sets of exercises for the muscles of the base of the pelvis to be performed during pregnancy, confinement and menopause to maintain their proper function. (5) Indicating factors predisposing to strain urinary incontinence with focus on possibilities of their reduction or elimination.

    Surgical site infections with elective laparoscopic cholecystectomy are less frequent and less severe, leading some to suggest that prophylactic antibiotics (PA) are no longer indicated. We compared the incidence of surgical site infections before and after an institutional practice change of withholding PA for elective laparoscopic cholecystectomy. Between May 7, 2013, and March 11, 2015, no PA were given to patients selected for elective cholecystectomy by two surgeons at a single center. The only patients excluded were those who received antibiotics before surgery for any reason. All others, including those at high risk for infection, were included. The incidence and severity of infections were compared with historical controls treated with prophylaxis by the same two surgeons from November 6, 2011, to January 13, 2013. There were 268 patients in the study group and 119 patients in the control group. Infection occurred in 3.0 per cent in the study group compared with 0.9 per cent in the controls (P = 0.29). All infections were mild except one. Based on these data, the routine use of PA for elective laparoscopic cholecystectomy is not supported.

    Thirty-five patients who were to begin pelvic irradiation for malignant disease were randomized to receive ibuprofen 400 mg P.O. q.i.d. during their radiotherapy or standard therapy for radiation-induced gastrointestinal symptoms. Seventeen of 19 patients in the ibuprofen group completed the protocol. There was no significant difference in the daily stool frequency between the ibuprofen and control patients during the 5 to 6 week course of pelvic irradiation; the incidence and severity of diarrhea was the same. There was no significant difference in the incidence of nausea reported by the patients but the severity of nausea was less in the ibuprofen group; none of the 17 patients in the ibuprofen group reported vomiting at any time, whereas, 27% of the patients in the control group reported vomiting. The difference was statistically significant (p < 0.05). The data suggest that prophylactic ibuprofen administration may be beneficial in reducing the severity of nausea and preventing radiation-induced vomiting in patients who receive pelvic irradiation

    Full Text Available The SMART trial is a UK-based, multicentre RCT comparing prophylactic radiotherapy and symptom-based (deferred radiotherapy in 203 patients with Malignant Pleural Mesothelioma who had undergone large bore pleural interventions. Using costs and quality of life data collected alongside the clinical trial, we will estimate the cost-effectiveness of prophylactic radiotherapy compared to deferred radiotherapy over a 1-year period.Healthcare utilization and costs were captured during the trial. Utility weights produced by the EQ-5D questionnaire were used to determine quality-adjusted life-years (QALY gained. The incremental cost-effectiveness ratio was calculated over the one-year trial period.Costs were similar in the immediate and deferred radiotherapy groups: £5480.40 (SD = £7040; n = 102 and £5461.40 (SD = £7770; n = 101 respectively. There was also no difference in QALY: 0.498 (95% CI: [0.45, 0.547] in the prophylactic radiotherapy group versus 0.525 (95% CI: [0.471, 0.580] in the deferred group. At a willingness to pay threshold of £30,000/QALY there was only a 24% chance that prophylactic radiotherapy was cost-effective compared to deferred radiotherapy.There was no significant effect of prophylactic radiotherapy on quality of life in the intervention group, nor was there any discernable decrease in healthcare costs. There is little evidence to suggest that prophylactic radiotherapy is a cost-effective intervention in this population.ISRCTN72767336 with ISRCTN.

    Only eight women out of one hundred diagnosed with ovarian epithelial cancers, which progressed to the clinical stage IV, survive 10 years. First line therapies: surgery, chemotherapy, and radiation therapy inflict very serious iatrogenic consequences. Passive immunotherapy of ovarian cancers offers only low efficacy. Prophylactic and therapeutic vaccines for ovarian cancers are not available. Interestingly, prophylactic vaccines for Hepatitis B Viruses (HBV) are very effective. The specific aim of this work was to design, synthesize, and administer biomolecules, which would engage prophylactic, vaccination-induced immunity for HBV towards killing of ovarian cancer cells with high specificity and efficacy. Tissue biopsies, ascites, and blood were acquired from the patients, whose identities were entirely concealed in accordance with the Declaration of Helsinki, pursuant to the Institutional Review Board approval, and with the Patients' informed consent. By biomolecular engineering, we have created a novel family of biomolecules: antibody × vaccine engineered constructs (AVEC: anti-HER-2 × HBsAg). We have collected the blood from the volunteers, and measured the titers of anti-HBV antibodies resulting from the FDA approved and CDC scheduled HBV vaccinations. We have acquired tumor biopsies, ascites, and blood from patients suffering from the advanced ovarian cancers. We have established cultures of HER-2 over-expressing epithelial ovarian cancers: OV-90, TOC-112D, SKOV-3, as well as human ovary surface epithelial (HOSE) and human artery endothelial (HAE) cells. Treatment of the HER-2+ ovarian cancer cells with AVEC: anti-HER-2 × HBsAg, accompanied by administration of blood drawn from patients with high titers of the anti-HBV antibodies, resulted in much higher therapeutic efficacy as compared to treatment with the naked anti-HER-2 antibodies alone and/or with the relevant isotype antibodies. This treatment had practically no effect upon the HOSE and HAE

    Active management of the third stage of labour has been shown to reduce the risk of postpartum haemorrhage (PPH) greater than 1000 mL. One aspect of the active management protocol is the administration of prophylactic uterotonics, however, the type of uterotonic, dose, and route of administration vary across the globe and may have an impact on maternal outcomes. To determine the effectiveness of prophylactic oxytocin at any dose to prevent PPH and other adverse maternal outcomes related to the third stage of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2013). Randomised or quasi-randomised controlled trials including pregnant women anticipating a vaginal delivery where prophylactic oxytocin was given during management of the third stage of labour. The primary outcomes were blood loss > 500 mL and the use of therapeutic uterotonics. Two review authors independently assessed trials for inclusion, assessed trial quality and extracted data. Data were checked for accuracy. This updated review included 20 trials (involving 10,806 women). Prophylactic oxytocin versus placebo Prophylactic oxytocin compared with placebo reduced the risk of PPH greater than 500 mL, (risk ratio (RR) 0.53; 95% confidence interval (CI) 0.38 to 0.74; six trials, 4203 women; T² = 0.11, I² = 78%) and the need for therapeutic uterotonics (RR 0.56; 95% CI 0.36 to 0.87, four trials, 3174 women; T² = 0.10, I² = 58%). The benefit of prophylactic oxytocin to prevent PPH greater than 500 mL was seen in all subgroups. Decreased use of therapeutic uterotonics was only seen in the following subgroups: randomised trials with low risk of bias (RR 0.58; 95% CI 0.36 to 0.92; three trials, 3122 women; T² = 0.11, I² = 69%); trials that performed active management of the third stage (RR 0.39; 95% CI 0.26 to 0.58; one trial, 1901 women; heterogeneity not applicable); trials that delivered oxytocin as an IV bolus (RR 0.57; 95% CI 0.39 to 0.82; one trial, 1000 women

    Full Text Available Studies in patients and chimpanzees that spontaneously clear Hepatitis C Virus (HCV have demonstrated that natural immunity to the virus is induced during primary infections and that this immunity can be cross protective. These discoveries led to optimism regarding prophylactic HCV vaccines and a number of studies in the chimpanzee model have been performed, all of which resulted in modified infections after challenge but did not always prevent persistence of the virus. Therapeutic vaccine strategies have also been pursued in an effort to reduce the costs and side effects associated with anti-viral drug treatment. This review summarizes the studies performed thus far in both patients and chimpanzees for prophylactic and therapeutic vaccination, assesses the progress made and future perspectives.

    To evaluate the ways of reduction complications during endoscopic procedures based on principals of professional ethics and improving the quality of working area. Data of fundamental literature, evidence based medicine, science publications and internet portals. Deontology is the fundamental principle of medical practice and one of the main factors of professional effectiveness. Complications in endoscopy are often the investigations of deviation from the deontological principals. The whole number of psychological factors influences on professional activity of endoscopists, where the emotional "burn-out" syndrome (EBS) occupies one of the main places. Prophylactic and timely relief of EBS serves improvement of the practical work quality. Creation of favorable working area is the strategically important task in prophylactics of endoscopy complications. The questions of practical realization of deontological principles in endoscopy are the subject of further discussion.

    Full Text Available BACKGROUND Postoperative nausea and vomiting is (PONV a very distressing complication and preventive measures are justified when the risk of PONV is very high. Ondansetron is the first 5-HT3 antagonist used alone or in combination for prophylaxis of PONV due to its lower cost. Granisetron and palonosetron are recently introduced 5-HT3 antagonists with greater affinity for 5-HT3 receptor and having longer half-life. Aim of the present study is to compare the antiemetic efficacy of ondansetron, granisetron and palonosetron in high-risk patients undergoing abdominal hysterectomy under general anaesthesia. METHODS After obtaining Institutional Ethical Committee approval and written informed consent from all the participants, 150 patients of ASA grade I & II, aged between 20-50 years and weight between 30-60 kg undergoing abdominal hysterectomy under general anaesthesia were assigned randomly in to three groups of 50 patients each using random number table receiving either ondansetron 4 mg (Group O or granisetron 2 mg (Group G or palonosetron 0.75 mg (Group P intravenously just before the induction of anaesthesia. Incidence and severity of nausea and frequency of retching and vomiting were recorded in each group at the end of 2-hour and then at 24-hour and 48-hour intervals. RESULTS The incidence of nausea during first two hours postoperatively was found to be 14(28% in Group O, which was found to be significantly higher than 6(12% in group G and 4(8% in group P (p value = 0.016. The incidence of vomiting was found to be 6(12% in group O, which was found to be significantly higher than 2(4% in both group G and group P (p value = 0.018. Number of complete responders was significantly higher in Group P and group G as compared to group O. Number of patients requiring rescue antiemetic treatment was significantly high in group O{10(20%} as compared to 3(6% in both the group G and group P.

    The first aim of this study was to evaluate combination antiemetic therapy consisting of 5-HT 3 receptor antagonists, neurokinin-1 receptor antagonists (NK-1RAs), and dexamethasone for multiple high emetogenic risk (HER) anticancer agents in bone and soft tissue sarcoma. The second aim was to compare the effectiveness of single-shot palonosetron and consecutive-day granisetron in a randomized, single-blinded crossover study. A single randomization method was used to assign eligible patients to the palonosetron or granisetron arm. Patients in the palonosetron arm received a palonosetron regimen during the first and third chemotherapy courses and a granisetron regimen during the second and fourth courses. All patients received NK-1RA and dexamethasone. Patients receiving the palonosetron regimen were administered 0.75 mg palonosetron on day 1, and patients receiving the granisetron regimen were administered 3 mg granisetron twice daily on days 1 through 5. All 24 patients in this study received at least 4 chemotherapy courses. A total of 96 courses of antiemetic therapy were evaluated. Overall, the complete response CR rate (no emetic episodes and no rescue medication use) was 34%, while the total control rate (a CR plus no nausea) was 7%. No significant differences were observed between single-shot palonosetron and consecutive-day granisetron. Antiemetic therapy with a 3-drug combination was not sufficient to control chemotherapy-induced nausea and vomiting (CINV) during chemotherapy with multiple HER agents for bone and soft tissue sarcoma. This study also demonstrated that consecutive-day granisetron was not inferior to single-shot palonosetron for treating CINV

    Hypoperfusion-induced thrombosis is an important mechanism for postsurgery stroke and cognitive decline, but there are no perioperative neuroprotectants to date. This study investigated whether prophylactic application of Edaravone, a free radical scavenger already used in treating ischemic stroke in Japan, can prevent infarct and cognitive deficits in a murine model of transient cerebral hypoxia-ischemia. Adult male C57BL/6 mice were subjected to transient hypoxic-ischemic (tHI) insult that consists of 30-minute occlusion of the unilateral common carotid artery and exposure to 7.5% oxygen. Edaravone or saline was prophylactically applied to compare their effects on cortical oxygen saturation, blood flow, coagulation, oxidative stress, metabolites, and learning-memory using methods that include photoacoustic imaging, laser speckle contrast imaging, solid-state NMR, and Morris water maze. The effects on infarct size by Edaravone application at different time points after tHI were also compared. Prophylactic administration of Edaravone (4.5 mg/kg×2, IP, 1 hour before and 1 hour after tHI) improved vascular reperfusion, oxygen saturation, and the maintenance of brain metabolites, reducing oxidative stress, thrombosis, white-matter injury, and learning impairment after tHI insult. Delayed Edaravone treatment after 3 h post-tHI became unable to reduce infarct size. Acute application of Edaravone may be a useful strategy to prevent postsurgery stroke and cognitive impairment, especially in patients with severe carotid stenosis. © 2015 American Heart Association, Inc.

    Full Text Available Postoperative surgical site infections are a major source of illness.  Infection results in longer hospital stay and higher costs.  Uses of preoperative antibiotics have been standardized and are being used routinely in most clinical surgeries and include controversial areas like breast surgery and herniorraphy. Objective of the study is to find out the benefit of prophylactic use of antibiotics in the management of herniorraphy.This project was carried out in a multispeciality tertiary care teaching hospital from 1st-30th April in 2002. Group 1 patients were treated prophylactically half an hour before surgery with single dose of I.V. antibiotics (injection.  Ampicillin 1gm + injection.  Gentamicin 80mg. Group 2 patients were treated post surgery with capsule. Ampicillin 500mg 4 times a day for 7 days and injection. Gentamicin twice a day for first 4 days. In case of group 1 patients only one out of 20 patients (5% was infected.  Whereas in-group 2 patients 5 out of 20 patients (25% were infected. The cost of prophylactic antibiotic treatment was Rs. 25.56 per patient.  The postoperative antibiotic treatment cost was Rs. 220.4 per patient.  That means postoperative treatment is around 8.62 times costlier than prophylactic treatment.             From this study it is evident that prophylactic (preoperative treatment is better than postoperative treatment with antibiotics.

    Objective Naratriptan has been reported to reduce the frequency of cluster headache. The purpose of this study was to determine whether naratriptan is effective as a prophylactic treatment for cluster headache in Japan. Methods We retrospectively reviewed all 43 patients with cluster headache who received preventive treatment with naratriptan from April 2009 to April 2015. The International Classification of Headache Disorders, 3rd Edition (beta version) (ICHD-3 beta) was used to diagnose cluster headache. This study was conducted at 3 centers (Department of Neurology, Saitama Medical University; Saitama Neuropsychiatric Institute; Saitama Medical University International Medical Center). Patients were recruited from these specialized headache outpatient centers. Naratriptan was taken before the patient went to bed. Results The study population included 30 men (69.8%) and 13 women (30.2%). Twenty-two cases received other preventive treatments (51.2%), while 21 cases only received naratriptan (48.8%). Among the 43 cases, 37 patients (86.0%) achieved an improvement of cluster headache on naratriptan. Conclusion Naratriptan has been suggested as a preventive medicine for cluster headache because of the longer the biological half-life in comparison to other triptans. The internal use of naratriptan 2 hours before attacks appears to achieve a good response in patients with cluster headache.

    Introduction Hemophilia A individuals displaying a similar genetic defect have heterogeneous clinical phenotypes. Aim To evaluate the underlying effect of exogenous factor (f)VIII on tissue factor (Tf)-initiated blood coagulation in severe hemophilia utilizing both empirical and computational models. Methods We investigated twenty-five clinically severe hemophilia A patients. All individuals were on fVIII prophylaxis and had not received fVIII from 0.25 to 4 days prior to phlebotomy. Coagulation was initiated by the addition of Tf to contact-pathway inhibited whole blood ± an anti-fVIII antibody. Aliquots were quenched over 20 min and analyzed for thrombin generation and fibrin formation. Coagulation factor levels were obtained and used to computationally predict thrombin generation with fVIII set to either zero or its value at the time of the draw. Results Due to prophylactic fVIII, at the time of the blood draw, the individuals had fVIII levels that ranged from hemophilia A. The combination of each individual's coagulation factors (outside of fVIII) determine each individual's baseline thrombin potential and may affect bleeding risk. PMID:21899664

  3. Pharmacological preconditioning with GYKI 52466: a prophylactic approach to neuroprotection

    Full Text Available Some toxins and drugs can trigger lasting neuroprotective mechanisms that enable neurons to resist a subsequent severe insult. This ‘pharmacological preconditioning’ has far-reaching implications for conditions in which blood flow to the brain is interrupted. We have previously shown that in vitro preconditioning with the AMPA receptor antagonist GYKI 52466 induces tolerance to kainic acid (KA toxicity in hippocampus. This effect persists well after washout of the drug and may be mediated via inverse agonism of G protein linked receptors. Given the amplifying nature of metabotropic modulation, we hypothesised that GYKI 52466 may be effective in reducing seizure severity at doses well below those normally associated with adverse side effects. Here we report that pharmacological preconditioning with low-dose GYKI imparts a significant protection against KA-induced seizures in vivo. GYKI (3 mg/kg, s.c., 90 to 180 min. prior to high-dose KA, markedly reduced seizure scores, virtually abolished all level 3 and level 4 seizures, and completely suppressed KA-induced hippocampal cFOS expression. In addition, preconditioned animals exhibited significant reductions in high frequency/high amplitude spiking and ECoG power in the delta, theta, alpha and beta bands during KA. Adverse behaviours often associated with higher doses of GYKI were not evident during preconditioning. The fact that GYKI is effective at doses well-below, and at pre-administration intervals well-beyond previous studies, suggests that a classical blockade of ionotropic AMPA receptors does not underlie anticonvulsant effects. Low-dose GYKI preconditioning may represent a novel, prophylactic strategy for neuroprotection in a field almost completely devoid of effective pharmaceuticals.

    Full Text Available Background: In the end of 2009, a large number of patients with cancer undergoing chemotherapy at the day care unit of a private hospital in Mumbai, India developed Burkholderia cepacia complex (BCC blood stream infection (BSI. Objective: The objectives were to identify the source of the outbreak and terminate the outbreak as rapidly as possible. Materials and Methods: All infection control protocols and processes were reviewed. Intensive training was started for all nursing staff involved in patient care. Cultures were sent from the environment (surfaces, water, air, intravenous fluids, disinfectants and antiseptics and opened/unopened medication. Results: A total of 13 patients with cancer with tunneled catheters were affected with BCC BSI. The isolates were of similar antimicrobial sensitivity. No significant breach of infection control protocols could be identified. Cultures from the prepared intravenous medication bags grew BCC. Subsequently, culture from unused vials of the antiemetic granisetron grew BCC, whereas those from the unopened IV fluid bag and chemotherapy medication were negative. On review, it was discovered that the outbreak started when a new brand of granisetron was introduced. The result was communicated to the manufacturer and the brand was withdrawn. There were no further cases. Conclusions: This outbreak was thus linked to intrinsic contamination of medication vials. We acknowledge a delay in identifying the source as we were concentrating more on human errors in medication preparation and less on intrinsic contamination. We recommend that in an event of an outbreak, unopened vials be cultured at the outset.

    The incidence of postoperative cardiac disturbances and the value of prophylactic digitalization were studied retrospectively in 143 patients undergoing pneumonectomy for carcinoma of the lung. Cardiac arrhythmias occurred in 29% and tachycardia episodes in 30% of the patients. The incidence of myocardial infarction was 2%. Operative mortality was 4%. The cardiac disturbances developed more often after left than after right pneumonectomy. The age of the patients, a history of angina pectoris or hypertension did not markedly increase the incidence of cardiac disturbances, neither did operative factors, such as pericardiotomy, left atrial resection, major bleeding nor postoperative empyema. Prophylactic digitalization significantly reduced postoperative cardiac disorders, their frequency being 33% in the group of patients who received prophylactic digitalis compared with 65% in the group that did not.

    In the present study, we sought to evaluate the prophylactic use of octreotide for asparaginase-induced acute pancreatitis. We reviewed the medical records of seven patients in two institutions who received prophylactic octreotide for re-administration of asparaginase after asparaginase-induced acute pancreatitis. Three patients completed asparaginase treatment without developing pancreatitis, and four experienced recurrence of pancreatitis. A literature search using PubMed identified four additional patients in whom asparaginase was successfully re-administered with octreotide. Prophylactic use of octreotide may, thus, be warranted for patients who would benefit from re-administration of asparaginase for cancer treatment; however, careful observation is needed to monitor for breakthrough recurrence of pancreatitis.

    To evaluate the efficacy of ampicillin versus cefazolin as prophylactic antibiotics prior to cesarean delivery in Rwanda. In a prospective, randomized, open-label, single-site study conducted between March and May 2012, the effects of prophylactic ampicillin versus cefazolin were compared among women undergoing cesarean delivery at the Centre Hospitalier Universitaire de Kigali, Rwanda. Postoperatively, participants were evaluated daily for infectious morbidity while in the hospital. Follow-up was done by phone and by appointment at the hospital within 2 weeks of delivery. During the study period, there were 578 total deliveries and 234 cesarean deliveries (40.4%). Overall, 132 women were enrolled in the study and randomized to receive either ampicillin (n=66) or cefazolin (n=66). No women were lost to follow-up. The overall infection rate was 15.9% (21/132). The infection rate in the ampicillin group and the cefazolin group was 25.8% (17/66) and 6.1% (4/66), respectively. Implementing a universal protocol in Rwanda of prophylactic cefazolin prior to cesarean delivery might reduce postoperative febrile morbidity, use of postoperative antibiotics, and number of postoperative days in hospital.

    Conclusion: We presented a new, effective and safe second line endoscopic hemostatic method in patients with therapy resistant post-papillotomy bleeding. Combination of prophylactic pancreatic stenting and thermal coagulation with coagulation forceps might be suggested as a rescue treatment in patients with severe post-papillotomy bleeding, resistant to standard endoscopic therapy.

    It is recommended that patients initiate triple antiemetic therapy with one of the 5-hydroxytryptamine receptor antagonists (5-HT(3) RAs), aprepitant (or its intravenous prodrug fosaprepitant) and dexamethasone prior to the start of highly emetogenic chemotherapy (HEC). However, the impact of 5-HT(3) RA selection within triple antiemetic regimens on the risk of uncontrolled chemotherapy-induced nausea and vomiting (CINV) with HEC has not been well studied. To assess the likelihood of an uncontrolled CINV event following antiemetic prophylaxis with the 5-HT(3) RA palonosetron + aprepitant/fosaprepitant + dexamethasone (palonosetron cohort) versus any of the other 5-HT(3) RAs + aprepitant/fosaprepitant + dexamethasone (other 5-HT(3) RA cohort) among single-day HEC cycles. Single-day HEC cycles (a gap of at least 5 days between two administrations) among patients with a cancer diagnosis and receiving antiemetic prophylaxis with the aforementioned regimens between 1/1/2006 and 6/30/2010 were identified from the IMS LifeLink claims database. Uncontrolled CINV events were identified through ICD-9-CM codes (nausea and vomiting), Current Procedural Terminology codes (hydration), rescue medications and/or use of antiemetic therapy from days 2-5 following HEC administration. Risks for an uncontrolled CINV event among all patients, and within breast cancer and multiple cancer subpopulations, were analyzed at cycle level using logistic multivariate regression models. A total of 8018 cycles for the palonosetron cohort and 1926 cycles for the other 5-HT(3) RA cohort (3574 and 978 patients, respectively) were analyzed. Single-day HEC cycles received by the palonosetron cohort had a significantly lower unadjusted risk of an uncontrolled CINV event (17.5 vs 20.7% for the other 5-HT(3) RA cohort; p = 0.0010), with a 17% lower adjusted risk for palonosetron-administered cycles (odds ratio: 0.83; 95% CI: 0.73-0.94; p = 0.0042).

    High-voltage measurements of generators, unit and service transformers and some significant motor drives used at a nuclear power plant are described in this paper. Thermovision measurements of electric machines and distribution systems are dealt with in the second part of the paper. Power electric equipment represent one of the most significant components of a nuclear power plant. Turbine mechanical energy is converted into the electrical energy within these equipment. Power generated by generators is transformed by transformers so that it can achieve appropriate parameters for both the transmission over the distribution system and the power plant service power supply. The service power supply switchboards and cables provide supply to motors and other consumers necessary for the nuclear power plant technological process. The whole complex of equipment has to be maintained in good technical conditions. It is necessary to make thermovision and prophylactic measurements to identify and verify the electric equipment technical condition. The mentioned measurements warn the operation staff in advance against both gradual deterioration of power connection contact resistances, i.e. power connections overheating, and the machine insulation systems condition deterioration. The operation staff try to prevent the electric equipment operation accidents by early removing the detected failures, thus, improving the nuclear safety. In order to provide the above-mentioned activities a special prophylactic measurement group was established at the NPP Bohunice in 1983. The group specialists make following types of measurements. 1. Prophylactic measurements of electric machines. Prophylactics of 220 MW generators and 6 MW service power generators; Prophylactics of both unit and service transformers and VHV bushings; Prophylactics of major 6 kV motor drives. 2. Thermovision measurements of current connections. (Abstract Truncated)

    Despite limited evidence, postoperative prophylactic antibiotics are often used in the setting of permanent pacemaker implantation or replacement. The aim of this study is to investigate the efficacy of postoperative antibiotics. Postoperative prophylactic antibiotics may be not clinically useful. We recruited 367 consecutive patients undergoing permanent pacemaker implantation or generator replacement at a tertiary referral center. Baseline demographics, clinical characteristics, and procedure information were collected, and all patients received preoperative prophylactic antibiotics. Postoperative prophylactic antibiotics were administered at the discretion of the treating physician, and all patients were seen in follow-up every 3 to 6 months for an average follow-up period of 16 months. The primary endpoint was device-related infection. A total of 110 patients were treated with preoperative antibiotics only (group 1), whereas 257 patients received both preoperative and postoperative antibiotics (group 2). After a mean follow-up period of 16 months, 1 patient in group 1 (0.9%) and 4 patients in group 2 (1.5%) experienced a device-related infection. There was no significant difference in the rate of infection between the 2 groups (P = 0.624). In the univariate analysis, only the age (60 ± 11 vs 75 ± 12 years, P antibiotics had a similar rate of infection as those treated with preoperative antibiotics alone. Further studies are needed to confirm these preliminary findings. © 2017 Wiley Periodicals, Inc.

    Full Text Available Expediency of the development of formulae and innovative technologies for production of prophylactic application drinks possessing antioxidant, probiotic and hepatoprotective properties with the use of the secondary dairy product – whey, as well as the domestic vegetable raw materials having a high content of bioactive substances has been substantiated.Formulation composition of the prophylactic drinks based on cheese whey, extract of Tagetes patula flowers and the berry filler “Strawberry” with the use of the response surface method has been developed. Bioactivity of the drinks and the complex quality indicator which accounts for the total influence of the bioactivity, organoleptic assessment and weight coefficients of the specified unit indicators were taken as the optimization criteria; as the independent factors that were varied in the course of the experiment, the mass fractions of the marigold flowers extract and the strawberries filler were selected. It is recommended that the mass fractions of the berry filler “Strawberry” and the extract of Tagetes patula flowers in the prophylactic drinks are set as 7 and 20 % of the finished product, accordingly. The practical mass fraction of the citric acid of 0.2 % was determined as it ensures high organoleptic characteristics of the finished drinks. Recommendations are given concerning development of innovative technologies of unfermented and fermented strawberry whey drinks of prophylactic application enriched with the extract of Tagetes patula flowers.

  17. Prophylactic fenbendazole therapy does not affect the incidence and onset of type 1 diabetes in non-obese diabetic mice.

    Fenbendazole (FBZ) is a common, highly efficacious broad-spectrum anthelmintic drug used to treat and limit rodent pinworm infections. However, the effect of its prophylactic use on the immune response of rodents is largely undefined. The non-obese diabetic (NOD) mouse is a model commonly used to study type 1 diabetes (T1D). Parasitic infections will inhibit diabetes development in NOD mice; thus, in the presence of contamination, prophylactic treatment with anthelmintics must be considered to maintain experimental research. Herein, we investigated the prophylactic use of FBZ in NOD mice to determine its effect on the incidence and onset of diabetes, lymphocyte sub-populations and T cell proliferative responses. NOD mice were separated into control and treatment groups. The treatment group received a diet containing FBZ. Animals were monitored for the incidence and onset of T1D. At matched time points, diabetic and non-diabetic mice were killed and splenic lymphocytes analyzed for various cell sub-populations and mitogen-induced proliferative responses using flow cytometry. Treated and control mice were monitored >23 weeks with no detectable effects on the incidence or onset of diabetes. Moreover, no significant differences were detected in lymphocyte sub-populations and mitogen-induced CD4(+) and CD8(+) proliferative responses between control and treatment groups. These results suggest that prophylactic FBZ treatment does not significantly alter the incidence or onset of diabetes in NOD mice. The prophylactic use of FBZ, therefore, presents a viable approach for the prevention of pinworm infection in precious experimental animals with substantial scientific and economic benefits.

    Full Text Available Abstract Background Prophylactic treatment is an important but under-utilised option for the management of migraine. Patients and physicians appear to have reservations about initiating this treatment option. This paper explores the opinions, motives and expectations of patients regarding prophylactic migraine therapy. Methods A qualitative focus group study in general practice in the Netherlands with twenty patients recruited from urban and rural general practices. Three focus group meetings were held with 6-7 migraine patients per group (2 female and 1 male group. All participants were migraine patients according to the IHS (International Headache Society; 9 had experience with prophylactic medication. The focus group meetings were analysed using a general thematic analysis. Results For patients several distinguished factors count when making a decision on prophylactic treatment. The decision of a patient on prophylactic medication is depending on experience and perspectives, grouped into five categories, namely the context of being active or passive in taking the initiative to start prophylaxis; assessing the advantages and disadvantages of prophylaxis; satisfaction with current migraine treatment; the relationship with the physician and the feeling to be heard; and previous steps taken to prevent migraine. Conclusion In addition to the functional impact of migraine, the decision to start prophylaxis is based on a complex of considerations from the patient's perspective (e.g. perceived burden of migraine, expected benefits or disadvantages, interaction with relatives, colleagues and physician. Therefore, when advising migraine patients about prophylaxis, their opinions should be taken into account. Patients need to be open to advice and information and intervention have to be offered at an appropriate moment in the course of migraine.

    Full Text Available BACKGROUND Febrile seizures occurring in a child older than one month during an episode of fever affect 2% to 4% of children in Great Britain and the United States and recur in 30%. Rapid-acting antiepileptics and antipyretics given during subsequent fever episodes have been used to avoid the adverse effects of continuous antiepileptic drugs. OBJECTIVE To evaluate the effectiveness and safety of antiepileptic and antipyretic drugs used prophylactically to treat children with febrile seizures. METHODS Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL (The Cochrane Library 2011. Issue 3; MEDLINE (1966 to May 2011; EMBASE (1966 to May 2011; Database of Abstracts of Reviews of Effectiveness (DARE (May 2011. No language restrictions were imposed. We also contacted researchers in the field to identify continuing or unpublished studies. Selection criteria: Trials using randomized or quasi-randomized patient allocation that compared the use of antiepileptic or antipyretic agents with each other, placebo or no treatment. Data collection and analysis: Two review authors (RN and MO independently applied pre-defined criteria to select trials for inclusion and extracted the pre-defined relevant data, recording methods for randomization, blinding and exclusions. Outcomes assessed were seizure recurrence at 6, 12, 18, 24, 36 months and at age 5 to 6 years in the intervention and non-intervention groups, and adverse medication effects. The presence of publication bias was assessed using funnel plots. MAIN RESULTS Thirty-six articles describing 26 randomized trials with 2740 randomized participants were included. Thirteen interventions of continuous or intermittent prophylaxis and their control treatments were analyzed. Methodological quality was moderate to poor in most studies. We could not do a meta-analysis for 8 of the 13 comparisons due to insufficient numbers of trials. No significant benefit for valproate, pyridoxine

    This is an update of the original Cochrane Review published in Cochrane Library, Issue 10, 2012.Hydatidiform mole (HM), also called a molar pregnancy, is characterised by an overgrowth of foetal chorionic tissue within the uterus. HMs may be partial (PM) or complete (CM) depending on their gross appearance, histopathology and karyotype. PMs usually have a triploid karyotype, derived from maternal and paternal origins, whereas CMs are diploid and have paternal origins only. Most women with HM can be cured by evacuation of retained products of conception (ERPC) and their fertility preserved. However, in some women the growth persists and develops into gestational trophoblastic neoplasia (GTN), a malignant form of the disease that requires treatment with chemotherapy. CMs have a higher rate of malignant transformation than PMs. It may be possible to reduce the risk of GTN in women with HM by administering prophylactic chemotherapy (P-Chem). However, P-Chem given before or after evacuation of HM to prevent malignant sequelae remains controversial, as the risks and benefits of this practice are unclear. To evaluate the effectiveness and safety of P-Chem to prevent GTN in women with a molar pregnancy. To investigate whether any subgroup of women with HM may benefit more from P-Chem than others. For the original review we performed electronic searches in the Cochrane Gynaecological Cancer Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 2, 2012), MEDLINE (1946 to February week 4, 2012) and Embase (1980 to 2012, week 9). We developed the search strategy using free text and MeSH. For this update we searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 5, 2017), MEDLINE (February 2012 to June week 1, 2017) and Embase (February 2012 to 2017, week 23). We also handsearched reference lists of relevant literature to identify additional studies and searched trial registries. We included randomised controlled trials

    Purpose: The main purpose of this study was to determine influential factors related to minor leukoencephalopathy (LEP) caused by moderate-dose methotrexate (MTX) and prophylactic cranial radiotherapy (CRT) in childhood hematopoietic malignancies. We also compared the incidence of LEP following this treatment to that reported in the literature following treatment with high-dose MTX alone. Methods and Materials: Thirty-eight pediatric patients of hematopoietic malignancies (37 acute lymphoblastic leukemias, 1 non-Hodgkin lymphoma) who were given CRT (18-24 Gy) as well as prophylactic intrathecal and per os MTX were studied for leukoencephalopathy by magnetic resonance (MR) imaging. All the patients were free from grave neuropsychiatric disturbances. The data were examined to elucidate the influential ones of five factors (patients' age, doses of intrathecal and per os MTX, dose of CRT, interval between treatment, and MR study) to develop LEP using multiple regression analysis. To compare the effect of moderate-dose MTX and prophylactic CRT on LEP to that of high-dose MTX alone, we conducted literature review. Results: Seven out of 38 patients (18%) developed LEP. From multiple regression analysis and partial correlation coefficients, the age and CRT dose seemed influential in the subsequent development of LEP. The incidence of LEP following treatment with moderate-dose MTX and prophylactic CRT appears to be less than that reported in the literature following treatment with intravenous high-dose MTX. However, even moderate-dose MTX in combination with CRT can result in a significant incidence of MR-detectable LEP, particularly in children 6 years of age or younger receiving 24 Gy. Conclusion: Leukoencephalopathy was caused by moderate-dose MTX and prophylactic CRT in pediatric patients, probably less frequently than by high-dose MTX treatment alone. The influential factors were patient's age and CRT dose

    Most patients who undergo chemotherapy have noted that nausea and vomiting are the most feared and distressing side-effects of cancer treatment (1). Nausea and vomiting from chemotherapy can be classified as acute, delayed, or anticipatory. Acute emesis generally occurs within 24 hours of chemotherapy administration; while delayed nausea and vomiting begin 24 hours after chemotherapy and may continue for up to one week. Anticipatory emesis occurs prior to chemotherapy in patients who anticipate another episode by sight, odors or memory of the place where acute nausea and vomiting occurred (2, 3). Different neurotransmitters found in the gastrointestinal tract (GIT) and central nervous system (CNS) mediate the pathophysiology of chemotherapy induced nausea and vomiting (CINV). These include dopamine, histamine, acetycholine, serotonin, and substance P; which act directly and indirectly on the vomiting center located in the lateral reticular formation of the medulla (1, 4). Substance P is a member of the tachykinins family of neuropeptides. The biological activity of this substance is to induce vomiting mediated by neurokinin-1 (NK1) receptors located primarily in the GIT and the CNS (5). Both Nk1 receptors and substance P play a significant role in the pathogenesis of acute and delayed CINV. (author)

    Purpose: To develop an evidence-based clinical practice guideline that would address the following questions: (a) What is the role of prophylactic cranial irradiation (PCI) in patients with limited or extensive stage small-cell lung cancer (SCLC) who have achieved complete remission in response to induction therapy (chemotherapy or chemoradiotherapy)? (b) What dose and fractionation schedules of PCI are optimal? (c) Does the use of PCI in patients with SCLC in complete remission affect quality of life? Survival, disease-free survival, quality of life, and adverse effects were the outcomes of interest. Methods and Materials: A systematic review of the published literature was undertaken to provide the data for an evidence-based practice guideline. Results: Six randomized controlled trials and one fully published individual patient data meta-analysis were included in the systematic review of the evidence. For patients who have achieved complete response after induction therapy, there is evidence of a disease-free survival benefit (4 of 6 trials) and an overall survival benefit (meta-analysis). There is insufficient evidence to make a definitive recommendation with respect to dose. There is some indication that 30-36 Gy in 2-3 Gy per fraction, or a biologically equivalent dose, may produce a better outcome than a lower dose or less aggressive fractionation regimen. The schedule commonly used in Canada is 25 Gy in 10 fractions over 2 weeks. Data from further research, including a trial currently ongoing that compares 25 Gy in 10 fractions with 36 Gy in 18 fractions, will be required to determine optimal dose of PCI. There is insufficient evidence to make recommendations concerning the optimal timing of PCI in relation to the administration of chemotherapy. Lung DSG members generally felt that it should be given as soon as possible after completion of chemotherapy. There is evidence from trials with data for up to 2 years of follow-up that prophylactic cranial

    This study aims to evaluate the effect of the prophylactic continuous positive airway pressure (CPAP) administration in the delivery room to newborns who were delivered by elective cesarean section (CS). Inborn infants with gestational age between 34(0/7) to 38(6/7) and born by elective CS were prospectively randomized to receive either prophylactic CPAP for 20 minutes via face mask or standardized care without CPAP in the delivery room. Primary outcomes were the incidence of transient tachypnea of the newborn (TTN) and neonatal intensive care unit (NICU) admission due to respiratory distress. A total of 259 infants with a mean gestational age of 37.7 ± 0.8 weeks and birth weight of 3,244 ± 477 g were included. A total of 134 infants received prophylactic CPAP and 125 received control standard care. The rate of NICU admission was significantly lower in prophylactic CPAP group (p = 0.045). Although the rate of TTN was lower in the prophylactic CPAP group, the difference was not statistically significant (p = 0.059). The rate of NICU admission due to respiratory distress was significantly higher in late-preterm cohort than early-term cohort (p CPAP administration decreases the rate of NICU admission without any side effect in late-preterm and early-term infants delivered by elective CS.

    Primary membranous nephropathy is associated with increased risk of venous thromboembolic events, which are inversely correlated with serum albumin levels. To evaluate the potential benefit of prophylactic anticoagulation (venous thromboembolic events prevented) relative to the risk (major bleeds), we constructed a Markov decision model. The venous thromboembolic event risk according to serum albumin was obtained from an inception cohort of 898 patients with primary membranous nephropathy. Risk estimates of hemorrhage were obtained from a systematic literature review. Benefit-to-risk ratios were predicted according to bleeding risk and serum albumin. This ratio increased with worsening hypoalbuminemia from 4.5:1 for an albumin under 3 g/dl to 13.1:1 for an albumin under 2 g/dl in patients at low bleeding risk. Patients at intermediate bleeding risk with an albumin under 2 g/dl have a moderately favorable benefit-to-risk ratio (under 5:1). Patients at high bleeding risk are unlikely to benefit from prophylactic anticoagulation regardless of albuminemia. Probabilistic sensitivity analysis, to account for uncertainty in risk estimates, confirmed these trends. From these data, we constructed a tool to estimate the likelihood of benefit based on an individual’s bleeding risk profile, serum albumin level, and acceptable benefit-to-risk ratio (http://www.gntools.com). This tool provides an approach to the decision of prophylactic anticoagulation personalized to the individual’s needs and adaptable to dynamic changes in health status and risk profile.

    AIM: To investigate the role of prophylactic antibiotics in the reduction of mortality of severe acute pancreatitis (SAP) patients, which is highly questioned by more and more randomized controlled trials (RCTs) and meta-analyses. METHODS: An updated meta-analysis was performed. RCTs comparing prophylactic antibiotics for SAP with control or placebo were included for meta-analysis. The mortality outcomes were pooled for estimation, and re-pooled estimation was performed by the sensitivity analysis of an ideal large-scale RCT. RESULTS: Currently available 11 RCTs were included. Subgroup analysis showed that there was significant reduction of mortality rate in the period before 2000, while no significant reduction in the period from 2000 [Risk Ratio, (RR) = 1.01, P = 0.98]. Funnel plot indicated that there might be apparent publication bias in the period before 2000. Sensitivity analysis showed that the RR of mortality rate ranged from 0.77 to 1.00 with a relatively narrow confidence interval (P antibiotic prophylaxis. CONCLUSION: Current evidences do not support prophylactic antibiotics as a routine treatment for SAP, but the potentially benefited sub-population requires further investigations. PMID:22294832

    To evaluate the effectiveness of intrapartum prophylactic amnioinfusion in pregnancies complicated by oligohydramnios. Randomized controlled trials of prophylactic amnioinfusion in women with oligohydramnios were identified using computerized databases, index reviews, and references cited in original studies and review articles. We evaluated, abstracted data from, and analyzed randomized studies of prophylactic intrapartum amnioinfusion in women with oligohydramnios. In every study the group allocation was based exclusively on presence of oligohydramnios. Only published studies with clearly documented outcome data were included. The quality of each trial was evaluated for methodology, inclusion and exclusion criteria, adequacy of randomization, amnioinfusion protocols, definition of outcomes, and statistical analyses. The trials were evaluated concerning cesarean deliveries for fetal heart rate (FHR) abnormalities, overall cesarean rates, acidemia at birth, intrapartum fetal heart rate abnormalities, Apgar scores under 7 at 5 minutes, and postpartum endometritis. Thirty-five studies were identified, of which 14 met the inclusion criteria for this systematic review. They included 1533 patients, 793 in the amnioinfusion group, and 740 controls. Odds ratios (OR) with their 95% confidence intervals (CI) for each outcome were calculated. We calculated an estimate of the OR and risk difference for dichotomous outcomes using random and fixed-effects models. A test of homogeneity was done across studies. Women with oligohydramnios who received intrapartum amnioinfusion had lower incidence of cesarean for FHR abnormalities (OR 0.23; 95% CI 0.15, 0.35). Intrapartum amnioinfusion also was associated with lower overall rates of cesarean deliveries (OR 0.52; 95% CI 0.40, 0. 68), acidemia at birth (OR 0.40; 95% CI 0.30, 0.55), FHR abnormalities during labor (OR 0.24; 95% CI 0.17, 0.34), and Apgar scores under 7 at 5 minutes (OR 0.52; 95% CI 0.29, 0.91).

    Central nervous system (CNS) prophylaxis is required during initial treatment of non-Hodgkin lymphoma (NHL) subtypes that carry a high risk of CNS involvement. Intrathecal (IT) liposomal cytarabine, a formulation with prolonged half-life, has been shown to be safe and effective in the treatment of meningeal disease in patients with high-grade lymphoma. We retrospectively reviewed all adult patients with high-grade NHL that received prophylactic therapy with IT liposomal cytarabine and developed neurologic complications in our institution between April 2007 and May 2009. We recorded information on hospital admission, chemotherapy regimens, clinical features, neuroimaging, cerebrospinal fluid, neurophysiology data, and outcome. Neurotoxicity was graded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC). Four of fourteen patients (28%) developed moderate or severe neurotoxicity (grades 2 and 3 of the NCI-CTC), manifested as conus medullaris/cauda equine syndrome or pseudotumour cerebri-like syndrome, after a median of 3.5 IT courses of liposomal cytarabine. All patients had received corticosteroids to prevent arachnoiditis. Liposomal cytarabine given via the IT route, even with concomitant corticosteroid administration, can result in significant neurotoxicity in some patients. We discuss the potential pathogenesis of these effects and suggest hypothetical therapeutic measures to prevent these complications. Specialists should be aware of these possible complications when administering prophylactic IT liposomal cytarabine in high-grade NHL patients, and additional prospective studies should be conducted to more clearly delineate the frequency and characteristics of these complications.

    The optimal approach is controversial in asymptomatic patients who are coincidentally found to have evidence of an accessory pathway (AP) on an ECG. The risk of sudden cardiac death (SCD) is low, and the risk of developing symptoms also appears to be low, although a wide range of incidences have been reported. In our trial, we tested the hypothesis that if prophylactic accessory-pathway ablation performed at the time of the initial electrophysiological testing would improve the long-term outcome in asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern. Recruitment of patients began on February 1, 2004, and ended on February 5, 2009. All 110 asymptomatic patients were hospitalized and underwent electrophysiological testing the same day to assess the inducibility of atrioventricular reciprocating tachycardia. The anterograde effective refractory period of the accessory pathway was defined as the longest coupling interval at which anterograde block in the bypass tract was observed. For the statistical analysis, the statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, USA). Of 110 asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern, 80 patients were ablated. Ablation group consisted of these patients. Control group consisted of remaining 30 and were divided into two groups according to the anterograde effective refractory period of the accessory pathway. There was no significant difference between three groups in terms of arrhythmic events (p: 0.58). Asymptomatic patients with the Wolff-Parkinson-White syndrome do not require prophylactic ablation, since they remain asymptomatic for many years.

    This study was designed to evaluate the efficacy of CNS-prophylaxis with high-dose methotrexate (MTX). Seventy children with previously untreated acute lymphoblastic leukemia (ALL) entered to this study between July 1978 and December 1980. According to initial white blood count (WBC), they were stratified to induce remission with; vincristine and prednine in low initial WBC ( lt 25,000/mm 3 ) group and these two agents plus adriamycin in high initial WBC ( gt 25,000/mm 3 ) group. After inducing remission, 62 children who achieved CR, received different CNS-prophlaxis; using a regimen of three doses of weekly high-dose MTX (1,000 mg/m 2 ) 6-hour infusion, which was repeated every 12 weeks-Group A (n = 14); high-dose MTX followed by 2400 rad cranial irradiation plus three doses of i.t. MT X-Group B (n = 15), 2400 rad cranial irradiation plus three doses of i.t. MTX-Group C (n = 16), and in 17 patients with high initial WBC, same as in Group A-Group D (n = 17). During an intravenous 6-h infusion of MTX at a dose of 1,000 mg/m 2 , the CSF concentration of MTX rose to 2.3 +- 2.4 x 10 -6 M after initiation of infusion and remained in 10 -7 M level for 48 hours. CNS-leukemia terminated complete remission in one of 14 children in Group A, two of 15 in Group B, two of 16 in Group C and two of 17 in Group D. The cumulative incidence of CNS-leukemia at 20 months calculated by the technique of Kaplan and Meier was 0% i n Group A, 18.1% in Group B, 7.1% in Group C and 50.8% in Group D. There was no statistical difference among Groups A, B and C. These data suggested that CNS-prophylaxis with high-dose intravenous MTX was effective as well as 2400 rad cranial irradiation plus three doses of i.t. MTX in childhood ALL with low initial WBC.

    There exists few pediatric data on the safety and efficacy of prophylactic antibiotics during chemotherapy-induced agranulocytosis. We prospectively studied the incidence of infection-related fever in 38 children, aged 2-16 years, with acute myeloid leukemia (AML) over 121 chemotherapy treatment cycles. A prophylactic group (n = 18) was given either vancomycin/cefepime (400 mg/m(2), q12 h/50 mg/kg, q12 h) or piperacillin/tazobactam (110 mg/kg, q12 h). Control patients (n = 20) received no preventive antibiotics. The prophylactic group (59 treatment cycles) experienced fever less frequently than the control group (0.4 vs. 0.9 events; p chemotherapy-induced agranulocytosis can effectively reduce the incidence of infectious fever and can shorten the average length of hospital stay, improving treatment success and quality of life. © 2014 S.

    Trema orientalis (T. orientalis Linn) has been used in the management of malaria in the western part of Nigeria and despite its application in ethnomedicine, there is dearth of scientific evidence to justify the acclaimed prophylactic antimalarial usage of the plant. The aim of this study is to assess the in vitro antiplasmodial cell-free assay and chemopreventive efficacy of the methanol extract of the stem bark of T. orientalis and its fractions as a prophylactic regimen for malaria prevention. Also, the antimicrobial activities of the extract and the fractions were investigated. Vacuum liquid chromatography was used to obtain dichloromethane, ethylacetate and methanol fractions from the methanol extract of T. orientalis. The fractions were tested for their prophylactic and cell-free antimalarial activity using murine models and β-hematin formation assay respectively. Disc diffusion method was used to determine the antibacterial activity of the extract and its fractions against both Gram-positive and Gram-negative bacteria. In the prophylactic experiment, dichloromethane (DCMF), methanol fraction (MF) and extract (ME) (in this order) showed significant chemopreventive effects against P. berghei invasion of the red blood cells when compared with both Sulfadoxine-Pyrimethamine (SP) and untreated controls. Results of the in vitro study showed that the DCMF had the highest effect in preventing the formation of β-hematin when compared with other fractions. The DCMF also had the highest percentage inhibition of β-hematin formation when compared with chloroquine. The extract and fractions showed a concentration dependent antibacterial activity. Methanol extract had a pronounced inhibitory effect on Enterobacter cloaca ATCC 13047 and Enterococcus faecalis ATCC 29212. Serratia mercescens ATCC 9986 and Pseudomonas aeruginosa ATCC 19582 were the most susceptible bacteria. The results obtained showed that both extract and fractions of T. orientalis possessed

  16. Current Evidence regarding Prophylactic Antibiotics in Head and Neck and Maxillofacial Surgery

    Science.gov (United States)

    2014-01-01

    Antibiotic prophylaxis is commonly used to decrease the rate of infections in head and neck surgery. The aim of this paper is to present the available evidence regarding the application of antibiotic prophylaxis in surgical procedures of the head and neck region in healthy patients. A systemic literature review based on Medline and Embase databases was performed. All reviews and meta-analyses based on RCTs in English from 2000 to 2013 were included. Eight out of 532 studies fulfilled all requirements. Within those, only seven different operative procedures were analyzed. Evidence exists for the beneficial use of prophylactic antibiotics for tympanostomy, orthognathic surgery, and operative tooth extractions. Unfortunately, little high-level evidence exists regarding the use of prophylactic antibiotics in head and neck surgery. In numerous cases, no clear benefit of antibiotic prophylaxis has been shown, particularly considering their potential adverse side effects. Antibiotics are often given unnecessarily and are administered too late and for too long. Furthermore, little research has been performed on the large number of routine cases in the above-mentioned areas of specialization within the last few years, although questions arising with respect to the treatment of high-risk patients or of specific infections are discussed on a broad base.

    The aim of this study was to systematically review the literature on antibiotic prophylaxis in gynaecologic surgeries to prevent inflammatory complications after gynaecological operations. The study was carried out as a systematic review. Only randomised controlled trials of women undergoing gynaecological surgery were included. The Medline and the Cochrane library databases were searched from 1966 to 2016. The trials must have investigated an antibiotic intervention to prevent an inflammatory complication after gynaecological surgery. Trials were excluded if they were not randomised, uncontrolled or included obstetrical surgery. Prophylactic antibiotics prevent inflammatory complications after gynaecological surgery. Prophylactic antibiotics are more effective in surgery requiring access to the peritoneal cavity or the vagina. Cefotetan appears to be more capable in preventing the overall inflammatory complication rate than cefoxitin or cefazolin. No benefit has been shown for the combination of antibiotics as prophylaxis. No difference has been shown between the long-term and short-term use of antibiotics. There is no need for the primary use of an anaerobic antibacterial agent. Antibiotics help to prevent postoperative inflammatory complications after major gynecologic surgeries.

    Although topical agents for the treatment of tinea capitis decrease viable fungal elements and reduce shedding, their use as a prophylactic agent has not been investigated. This study evaluated the effectiveness of a prophylactic ketoconazole shampoo (Nizoral 2%) protocol to reduce the number of clinically evident tinea capitis infections in a high-risk African American, urban population. We conducted a retrospective analysis of a ketoconazole prophylaxis protocol that was implemented at an urban pediatric clinic for medically fragile children. Patients at high risk for tinea capitis received twice-weekly ketoconazole shampoo. The primary outcome of the study was a reduction in the number of documented tinea capitis infections between the 12-month preprotocol and 12-month postprotocol periods. A secondary outcome included the evaluation of predisposing risk factors for acquiring tinea infections. Ninety-seven patients, with a mean age of 8.06 years, were included. Most patients (78%) were African American. There were a total of 13 tinea capitis infections during the 12-month preprotocol period. During the 12-month postprotocol period, 41 infections were documented: 37 (90.2%) in the prophylaxis group and 4 (9.8%) in the nonprophylaxis group. The average numbers of per-patient infections in the postprotocol period were 0.79 and 0.08 in the prophylaxis and nonprophylaxis groups, respectively. Initiation of prophylaxis did not reduce tinea capitis infections (p=NS). Previous history of infection and a high level of care were significant predictors of infections (pshampoo) prophylaxis protocol.

    PurposeTo appraise the efficacy and safety of prophylactic uterine artery embolization in pregnancy termination with placenta previa.MethodsA cohort of 54 consecutive patients with placenta previa underwent prophylactic uterine artery embolization before vaginal delivery from February 2012 to March 2015. Vaginal delivery was attempted in all patients. Cesarean section or hysterectomy was introduced when vaginal delivery failed.ResultsVaginal delivery succeeded in 50 patients (93.6%) and failed in 4 patients (6.4%), thereupon converted to cesarean delivery. No patients resorted to hysterectomy. Six patients (11.1%) underwent blood transfusion. None of clinical characteristics, including maternal age, gestational age, history of abortion, history of cesarean delivery, and volume of vaginal bleeding, was significantly associated with complete placenta previa (P > 0.05). However, patients with complete placenta previa had a significantly lower successful rate of vaginal delivery than did patients without complete placenta previa (81 vs 100%, P = 0.038). The rate of complications was 3.7%. No major complications were observed.ConclusionUterine artery embolization is an effective and safe technique to assist pregnancy termination with placenta previa, which may lower the risk of cesarean section, hysterectomy, and blood transfusion.

    PurposeTo study the effectiveness of prophylactic embolization of hepaticoenteric arteries to prevent gastrointestinal complications during radioembolization.MethodsA PubMed, Embase and Cochrane literature search was performed. We included studies assessing both a group of patients with and without embolization.ResultsOur search revealed 1401 articles of which title and abstract were screened. Finally, eight studies were included investigating 1237 patients. Of these patients, 456 received embolization of one or more arteries. No difference was seen in the incidence of gastrointestinal complications in patients with prophylactic embolization of the gastroduodenal artery (GDA), right gastric artery (RGA), cystic artery (CA) or hepatic falciform artery (HFA) compared to patients without embolization. Few complications were reported when microspheres were injected distal to the origin of these arteries or when reversed flow of the GDA was present. A high risk of confounding by indication was present because of the non-randomized nature of the included studies.ConclusionIt is advisable to restrict embolization to those hepaticoenteric arteries that originate distally or close to the injection site of microspheres. There is no conclusive evidence that embolization of hepaticoenteric arteries influences the risk of complications.

    AIMS: ICD implantation for primary prevention of sudden cardiac death in patients with left ventricular systolic dysfunction (ejection fraction <\\/= 35%) has increased since the publication of the SCD-HEFT and MADIT-II data. The aim of this study is to examine the effectiveness and safety of prophylactic ICD use in a community heart failure population and to assess the impact on patient\\'s quality of life. METHODS AND RESULTS: Seventy-one ICDs were inserted between the years 2002 and 2006. The mean follow-up from time of insertion was 24 +\\/- 11 months. Eighteen patients (25%) had potentially life-saving therapy. Seven (10%) patients received inappropriate shocks. Complications were encountered in five patients (7%). CONCLUSION: In a community heart failure population, prophylactic ICD implantation is associated with a high incidence of life-saving therapy, a low complication rate and a high level of tolerability. These data indicate translation of clinical trial benefits to the general heart failure population.

    Full Text Available BACKGROUND AND OBJECTIVES: Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery bypass graft surgery bleeding. METHODS: A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1 g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post-operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. RESULTS: There were no significant differences between intra-operative packed red blood cells infusion in the studied groups (1.0 ± 1.4 in fibrinogen group, and 1.3 ± 1.1 in control group. Less postoperative bleeding was observed in the fibrinogen group (477 ± 143 versus 703 ± 179, p = 0.0001. Fifteen patients in the fibrinogen group and 21 in the control group required post-op packed red blood cells infusion (p = 0.094. No thrombotic event was observed through 72 h after surgery. CONCLUSION: Prophylactic fibrinogen reduces post-operative bleeding in patients undergoing coronary artery bypass graft.

    2013-01-01

    Introduction The current mainstream practice in otolaryngology departments relating to the use of prophylactic antibiotics in epistaxis patients requiring nasal packing is highly variable. This is due primarily to the lack of any validated guidelines. As such, we introduced a new treatment algorithm resulting in significant reduction of use in the systemic antibiotics, with emphasis instead on the use of topical antibiotics. The results were validated through a complete audit cycle. Methods A total of 57 patients undergoing nasal packing for spontaneous epistaxis were studied. Reaudit occurred after the implementation of new guidelines. Telephone surveys were conducted six weeks after hospital discharge, assessing infective nasal symptoms as well as rebleeding and readmission rates. Results Systemic antibiotic prescribing in anterior nasal packing fell by 58.2% between audit cycles with no statistically significant associated increase in infective nasal symptoms, rebleeding or readmission rates six weeks following hospital discharge. Conclusions Systemic prophylactic antibiotics are unnecessary in the majority of epistaxis patients with nasal packs. The use of topical antibiotics such as Naseptin® may be more appropriate, cheaper and as effective. Implementation of this treatment algorithm will help standardise systemic antibiotic usage in epistaxis patients with nasal packing and should reduce costs associated with unnecessary use of such medication.

    PurposeTo appraise the efficacy and safety of prophylactic uterine artery embolization in pregnancy termination with placenta previa.MethodsA cohort of 54 consecutive patients with placenta previa underwent prophylactic uterine artery embolization before vaginal delivery from February 2012 to March 2015. Vaginal delivery was attempted in all patients. Cesarean section or hysterectomy was introduced when vaginal delivery failed.ResultsVaginal delivery succeeded in 50 patients (93.6%) and failed in 4 patients (6.4%), thereupon converted to cesarean delivery. No patients resorted to hysterectomy. Six patients (11.1%) underwent blood transfusion. None of clinical characteristics, including maternal age, gestational age, history of abortion, history of cesarean delivery, and volume of vaginal bleeding, was significantly associated with complete placenta previa (P > 0.05). However, patients with complete placenta previa had a significantly lower successful rate of vaginal delivery than did patients without complete placenta previa (81 vs 100%, P = 0.038). The rate of complications was 3.7%. No major complications were observed.ConclusionUterine artery embolization is an effective and safe technique to assist pregnancy termination with placenta previa, which may lower the risk of cesarean section, hysterectomy, and blood transfusion.

    Globally, tobacco use causes approximately 6 million deaths per year, and predictions report that with current trends; more than 8 million deaths are expected annually by 2030. Cigarette smokings is currently accountable for more than 480,000 deaths each year in United States (US) and is the leading cause of preventable death in the US. On average, smokers die 10 years earlier than nonsmokers and if smoking continues at its current proportion among adolescents, one in every 13 Americans aged 17 years or younger is expected to die prematurely from a smoking-related illness. Even though there has been a marginal smoking decline of around 5% in recent years (2005 vs 2015), smokers still account for 15% of the US adult population. What is also concerning is that 41,000 out of 480,000 deaths results from secondhand smoke (SHS) exposure. Herein, we provide a detailed review of health complications and major pathological mechanisms including mutation, inflammation, oxidative stress, and hemodynamic and plasma protein changes associated with chronic smoking. Further, we discuss prophylactic interventions and associated benefits and provide a rationale for the scope of clinical treatment. Considering these premises, it is evident that much detailed translational and clinical studies are needed. Factors such as the length of smoking cessation for ex-smokers, the level of smoke exposure in case of SHS, pre-established health conditions, genetics (and epigenetics modification caused by chronic smoking) are few of the criteria that need to be evaluated to begin assessing the prophylactic and/or therapeutic impact of treatments aimed at chronic and former smokers (especially early stage ex-smokers) including those frequently subjected to second hand tobacco smoke exposure. Herein, we provide a detailed review of health complications and major pathological mechanisms including mutation, inflammation, oxidative stress, and hemodynamic and plasma protein changes associated with

    The monitoring of antimicrobial use is an essential step to control the selection and spread of antimicrobial resistance. Between January and October 2010 data on prophylactic and metaphylactic antimicrobial use were collected retrospectively on 50 closed or semi-closed pig herds. Ninety-three percent of the group treatments were prophylactic whereas only 7% were methaphylactic. The most frequently used antimicrobials orally applied at group level were colistin (30.7%), amoxicillin (30.0%), trimethoprim-sulfonamides (13.1%), doxycycline (9.9%) and tylosin (8.1%). The most frequently applied injectable antimicrobials were tulathromycin (45.0%), long acting ceftiofur (40.1%) and long acting amoxicillin (8.4%). The treatment incidences (TI) based on the used daily dose pig (UDD(pig) or the actually administered dose per day per kg pig of a drug) for all oral and injectable antimicrobial drugs was on average 200.7 per 1000 pigs at risk per day (min=0, max=699.0), while the TI based on the animal daily dose pig (ADD(pig) or the national defined average maintenance dose per day per kg pig of a drug used for its main indication) was slightly higher (average=235.8, min=0, max=1322.1). This indicates that in reality fewer pigs were treated with the same amount of antimicrobials than theoretically possible. Injectable products were generally overdosed (79.5%), whereas oral treatments were often underdosed (47.3%). In conclusion, this study shows that prophylactic group treatment was applied in 98% of the visited herds and often includes the use of critically important and broad-spectrum antimicrobials. In Belgium, the guidelines for prudent use of antimicrobials are not yet implemented. Copyright © 2012 Elsevier B.V. All rights reserved.

    Many head and neck cancer (HNC) survivors experience reduced quality of life due to radiotherapy (RT)-related dysphagia. The aim of this prospective randomized trial was to evaluate the impact of prophylactic swallowing exercises on swallowing-related outcomes in HNC patients treated with curative...... of the dysphagia outcomes during and after treatment. Adherence to exercises was poor and dropouts due to especially fatigue were very frequent in both groups. Systematic swallowing exercises had no impact on swallowing outcomes within the first year after RT. Despite repeated supervised sessions, adherence...

    The objective of the study was to compare the efficacy of palanosetron (0.25 mg), granisetron (3.0 mg) and ondansetron (8.0 mg) used as anti-emetics for the prevention of postoperative nausea/vomiting in patients undergoing middle ear surgery. The study was done among 75 adult patients (age group 30-45 years) of which 50 were males and rest (25) females, all of ASA I and ASA II. The patients were randomly allocated into 3 equal groups: Group I (n = 25) received injection palanosetron (0.25 mg) IV, group II (n = 25) received injection granisetron (3 mg) IV and group III (n = 25) received injection ondansetron (8.0 mg) IV at the end of the surgical procedure. A standard general anaesthesia technique was employed. Emetic episodes and safety assessments were performed during two periods of 0-6 hours in the postanaesthesia care unit and 6-24 hours in the ward after anaesthesia. The incidence of emesis-free patients during the 0-6 hours period was 100% for group I; 72% for group II and 56% for group III. During the 6-24 hours period incidence of emesis-free patients were 96% for group I; 56% for group II and 32% for group III. So to conclude, a single dose of palanosetron (0.25 mg) is a superior anti-emetic to granisetron (3.0 mg) or ondansetron (8.0 mg) in complete prevention of postoperative nausea and vomiting after middle ear surgery during the first 24 hours period.

  10. Eliminating Postoperative Nausea and Vomiting in Outpatient Surgery with Multimodal Strategies including Low Doses of Nonsedating, Off-Patent Antiemetics: Is “Zero Tolerance“ Achievable?

    Full Text Available For ondansetron, dexamethasone, and droperidol (when used for prophylaxis, each is estimated to reduce risk of postoperative nausea and/or vomiting (PONV by approximately 25%. Current consensus guidelines denote that patients with 0–1 risk factors still have a 10–20% risk of encountering PONV, but do not yet advocate routine prophylaxis for all patients with 10–20% risk. In ambulatory surgery, however, multimodal prophylaxis has gained favor, and our previously published experience with routine prophylaxis has yielded PONV rates below 10%. We now propose a “zero-tolerance” antiemetic algorithm for outpatients that involves routine prophylaxis by first avoiding volatile agents and opioids to the extent possible, using locoregional anesthesia, multimodal analgesia, and low doses of three nonsedating off-patent antiemetics. Routine oral administration (immediately on arrival to the ambulatory surgery suite of perphenazine 8 mg (antidopaminergic or cyclizine 50 mg (antihistamine, is followed by dexamethasone 4 mg i.v. after anesthesia induction (dexamethasone is avoided in diabetic patients. At the end of surgery, ondansetron (4 mg i.v., now off-patent is added. Rescue therapy consists of avoiding unnecessary repeat doses of drugs acting by the same mechanism: haloperidol 2 mg i.v. (antidopaminergic is prescribed for patients pretreated with cyclizine or promethazine 6.25 mg i.v. (antihistamine for patients having been pretreated with perphenazine. If available, a consultation for therapeutic acupuncture procedure is ordered. Our approach toward “zero tolerance” of PONV emphasizes liberal identification of and prophylaxis against common risks.

    To describe the benefits and optimum use of prophylactic antibiotics in users of therapeutic contact lenses (TCL). A microbiological study was carried out on samples from 33 patients who continuously wore TCL. The resistance to antibiotics of bacteria isolated in our health region was also reviewed. An assessment was also made on whether there were microorganisms of a higher pathogenic potential in TCL than conventional contact lenses, as reported in the literature. No bacteria were isolated from 17 (52%) of the 33 lenses studied. From the 16 (48%) remaining lenses, coagulase negative Staphylococci were isolated from 10 (62%), Propionibacterium acnes from 4 (25%), and Corynebacterium from 2 (13%). The high number of negative cultures and the presence of saprophytic bacteria indicate that prophylactic antibiotic treatment is not precise. The most frequent pathogenic bacteria found in contact lenses are strongly resistant to the current commercially available antibiotics. Copyright © 2012 Sociedad Española de Oftalmología.

    Full Text Available Herpes zoster (HZ occurs in older ages with activation of varicella-zoster virus (VZV which persists in a dormant phase within the dorsal root ganglia. The incidence of HZ in immunosuppressed patients is 20-100 times higher and the clinical progress is more severe than in immunocompetent individuals. A 48-year-old man who had been diagnosed with acute myelocytic leukemia type M3 and had been treated with immunosuppressive agents was admitted to our clinic. The patient was clinically diagnosed as having HZ. He was treated with acyclovir 800 mg five times daily for 7 days. In the consecutive three months, he attended our clinic again with similar complaints. The left cervical (C5, C6 dermatomes were involved at the fourth attack of HZ. Multinucleated giant cells were determined on the Tzanck smear. VZV DNA was detected by polymerase chain reaction (PCR. Treatment with valacyclovir 1 g three times daily for 14 days was prescribed and then, prophylactic treatment with valacyclovir 500 mg two times a day was administered. Although immunosuppressive treatment was continued, no new attacks of herpes zoster occurred. We think that prophylactic antiviral therapy should be initiated in immunosuppressive individuals who have recurrent herpes zoster attacks.

    Thrombocytopenia is a hallmark of dengue infection, and bleeding is a dreaded complication of dengue fever. Prophylactic platelet transfusion has been used to prevent bleeding in the management of dengue fever, although the evidence for its benefit is lacking. In adult dengue patients with platelet count Tan Tock Seng Hospital from January 2005 to December 2008. Baseline characteristics and clinical outcomes were compared between the non-transfused vs. transfused groups. Outcomes studied were clinical bleeding, platelet increment, hospital length of stay, intensive care unit admission and death. Of the 788 patients included, 486 received prophylactic platelet transfusion. There was no significant difference in the presence of clinical bleeding in the two groups (18.2% in non-transfused group vs. 23.5% in transfused group; P = 0.08). Patients in the transfused group took a median of 1 day longer than the non-transfused group to increase their platelet count to 50,000/mm3 or more (3 days vs. 2 days, P hospital stay in the non-transfused group was 5 days vs. 6 days in the transfused group (P50,000/mm3 and increasing length of hospitalization.

    There is limited published research studying the effect of antibiotic prophylaxis on surgical site infection (SSI) in dermatological surgery, and there is no consensus for its use in higher-risk cases. The objective of this study was to determine the effectiveness of a single oral preoperative 2 g dose of cephalexin in preventing SSI following flap and graft dermatological closures on the nose and ear. Prospective double-blinded, randomised, placebo-controlled trial testing for difference in infection rates. Primary care skin cancer clinics in North Queensland, Australia, were randomised to 2 g oral cephalexin or placebo 40-60 min prior to skin incision. 154 consecutive eligible patients booked for flap or graft closure following skin cancer excision on the ear and nose. 2 g dose of cephalexin administered 40-60 min prior to surgery. Overall 8/69 (11.6%) controls and 1/73 (1.4%) in the intervention group developed SSI (p=0.015; absolute SSI reduction 10.2%; number needed to treat (NNT) for benefit 9.8, 95% CI 5.5 to 45.5). In males, 7/44 controls and 0/33 in the intervention group developed SSI (p=0.018; absolute SSI reduction 15.9%; NNT for benefit 6.3, 95% CI 3.8 to 19.2). SSI was much lower in female controls (1/25) and antibiotic prophylaxis did not further reduce this (p=1.0). There was no difference between the study groups in adverse symptoms attributable to high-dose antibiotic administration (p=0.871). A single oral 2 g dose of cephalexin given before complex skin closure on the nose and ear reduced SSI.

    Full Text Available Background: Gabapentin is an antiepileptic drug. Its antiemetic effect is demonstrated in chemotherapy-induced acute and delayed onset of nausea and vomiting in breast cancer patients. Aim: To evaluate the antiemetic effect of gabapentin on incidence and severity of postoperative nausea and vomiting in laparoscopic cholecystectomy. Settings and Design: Double-blind, randomized, placebo-controlled study. Materials and Methods: Two hundred and fifty patients of ASA physical status I and II, scheduled for laparoscopic cholecystectomy were randomly assigned into two equal groups to receive 600 mg gabapentin or matching placebo two hours before surgery. Standard anaesthesia technique was used. Fentanyl was used as rescue postoperative analgesic. Ondansetron 4 mg was used intravenously as rescue medication for emesis. The total number of patients who had nausea or vomiting, and its severity and total fentanyl consumption in the first 24 hours were recorded. Statistical Analysis: "Z test" was used to test the significance of severity of post-operative nausea and vomiting between groups. Fentanyl consumed in each group (Mean±SD within 24 hrs was compared using student t test. P value< 0.05 was considered significant. Results: There were no demographic difference between the two groups. Incidence of post-operative nausea and vomiting within 24 hrs after laparoscopic cholecystectomy was significantly lower in gabapentin group (46/125 than in the placebo group (75/125 (37.8% vs 60%; P =0.04. There was a significantly decreased fentanyl consumption in gabapentin group (221.2±92.4 µg as compared to placebo group (505.9±82.0 µg; P =0.01. Conclusion: Gabapentin effectively suppresses nausea and vomiting in laparoscopic cholecystectomy and post-operative rescue analgesic requirement.

  16. Role of healthcare workers in early epidemic spread of Ebola: policy implications of prophylactic compared to reactive vaccination policy in outbreak prevention and control.

    Ebola causes severe illness in humans and has epidemic potential. How to deploy vaccines most effectively is a central policy question since different strategies have implications for ideal vaccine profile. More than one vaccine may be needed. A vaccine optimised for prophylactic vaccination in high-risk areas but when the virus is not actively circulating should be safe, well tolerated, and provide long-lasting protection; a two- or three-dose strategy would be realistic. Conversely, a reactive vaccine deployed in an outbreak context for ring-vaccination strategies should have rapid onset of protection with one dose, but longevity of protection is less important. In initial cases, before an outbreak is recognised, healthcare workers (HCWs) are at particular risk of acquiring and transmitting infection, thus potentially augmenting early epidemics. We hypothesise that many early outbreak cases could be averted, or epidemics aborted, by prophylactic vaccination of HCWs. This paper explores the potential impact of prophylactic versus reactive vaccination strategies of HCWs in preventing early epidemic transmissions. To do this, we use the limited data available from Ebola epidemics (current and historic) to reconstruct transmission trees and illustrate the theoretical impact of these vaccination strategies. Our data suggest a substantial potential benefit of prophylactic versus reactive vaccination of HCWs in preventing early transmissions. We estimate that prophylactic vaccination with a coverage >99% and theoretical 100% efficacy could avert nearly two-thirds of cases studied; 75% coverage would still confer clear benefit (40% cases averted), but reactive vaccination would be of less value in the early epidemic. A prophylactic vaccination campaign for front-line HCWs is not a trivial undertaking; whether to prioritise long-lasting vaccines and provide prophylaxis to HCWs is a live policy question. Prophylactic vaccination is likely to have a greater impact on the

    The aim of this meta-analysis was to investigate whether there are any positive effects of prophylactic antibiotic regimen on implant failure rates and post-operative infection when performing dental implant treatment in healthy individuals. An electronic search without time or language restrictions was undertaken in March 2014. Eligibility criteria included clinical human studies, either randomised or not. The search strategy resulted in 14 publications. The I(2) statistic was used to express the percentage of the total variation across studies due to heterogeneity. The inverse variance method was used with a fixed- or random-effects model, depending on the heterogeneity. The estimates of relative effect were expressed in risk ratio (RR) with 95% confidence interval. Six studies were judged to be at high risk of bias, whereas one study was considered at moderate risk, and six studies were considered at low risk of bias. The test for overall effect showed that the difference between the procedures (use versus non-use of antibiotics) significantly affected the implant failure rates (P = 0.0002), with a RR of 0.55 (95% CI 0.41-0.75). The number needed to treat (NNT) to prevent one patient having an implant failure was 50 (95% CI 33-100). There were no apparent significant effects of prophylactic antibiotics on the occurrence of post-operative infections in healthy patients receiving implants (P = 0.520). A sensitivity analysis did not reveal difference when studies judged as having high risk of bias were not considered. The results have to be interpreted with caution due to the presence of several confounding factors in the included studies. © 2014 John Wiley & Sons Ltd.

Despite vitamin D therapy, BMC decreased from the baseline in 15 (32.6%) children receiving 1000 IU/day vitamin D and in 17 (36.9%) children receiving 400 IU/day vitamin D. There were no adverse effects attributable to vitamin D. The 1000 IU/day dose is marginally more effective than 400 IU/day and it is likely than an even larger dose is required. Further research is required to assess the efficacy and safety of vitamin D doses higher than 1000 IU/day.

No significant difference was observed in sex, gestational age, birth weight, mode of delivery, multifetal gestation and birth order between two groups. The rate of ductal closure was 75% and 50% in prophylaxis group and control group respectively (P=0.27. Conclusion: Our study demonstrated that prophylactic paracetamol is ineffective in PDA closure, although the rate of ductal closure between two groups seems remarkable. Paracetamol as a new strategy for PDA closure because of cost effectiveness and harmlessness may be used in future. However, we presume larger sample size studies are needed to show the efficacy of paracetamol, side effects, and complications in PDA prophylaxis treatment.

    Full Text Available Recent studies of military personnel who have deployed to Iraq and Afghanistan have reported a number of combat-related psychiatric disorders such as posttraumatic stress disorder, depression, and traumatic brain injury. This case report involves a 27-year-old male active-duty US military service member who developed severe depression, psychotic hallucinations, and neuropsychological sequelae following the prophylactic use of the antimalarial medication mefloquine hydrochloride. The patient had a recent history of depression and was taking antidepressant medications at the time of his deployment to the Middle East. Psychiatrists and other health care providers should be aware of the possible neuropsychiatric side effects of mefloquine in deployed military personnel and should consider the use of other medications for malaria prophylaxis in those individuals who may be at increased risk for side effects.

    There will be a continued imperative to recruit large numbers of healthy volunteers to early phase prophylactic HIV vaccine (PHV) trials. We studied mechanisms associated with participation in two related phase II PHV trials. The most cited reasons for volunteering were altruism and a personal connection to HIV. The most successful recruiting strategies targeted organisations dealing with HIV, health or social issues, or were directed to large audiences through the mass media. However, circulated emails and word of mouth were the most resource-effective approaches. Group discussions and the collection of a pool of potential volunteers were much less effective than one-to-one discussions and immediate screening after recruitment. We utilised our findings to devise key recommendations to assist PHV trial teams who are planning future studies.

    AIM: To evaluate the effectiveness of paracetamol as a prophylactic analgesic for hysterosalpingography (HSG). DESIGN: A prospective double blind randomized controlled trial comparing one 1 g of paracetamol (SmithKline Beecham, Brentford, U.K.) to placebo taken 30 min before HSG. One hundred consecutive out-patients were studied prospectively. The analgesic effectiveness during the procedure and at 24 h and 1 week post procedure was analysed by a postal pain score questionnaire. Additional data on the ethnicity of the patient, sex and level of experience of the radiologist performing the hysterosalpingogram, the parity of the patient, the ease of the procedure, and whether pathology was identified were also recorded. RESULTS: Eighty-eight patients (88%) replied, 39 (44%) received paracetamol and 49 placebo (56%). During the procedure 3/39 (7%) of women in the paracetamol group were pain-free compared to 9/49 (18%) in the placebo group, which was not significant (P = 0.11). At 24 h, 15/39 (38%) of women in the paracetamol group were pain-free compared to 20/49 (41%) in the placebo group, which was not significant (P = 0.82). At 1 week, 27/39 (69%) of women in the paracetamol group were pain-free compared to 29/49 (59%) in the placebo group, which was not significant (P = 0.33). No significant difference in mean pain scores was determined during the procedure (P 0.91), or at 24 h post procedure (P = 0.94). Similarly, no difference in mean pain scores was identified with regard to the ethnicity of the patient, the sex of the radiologist performing the procedure, the level of experience of the radiologist performing the procedure, or whether pathology was present or not. Difficult cannulations were associated with higher mean pain scores, however, there was no difference in mean pain scores between the paracetamol or placebo groups for both easy and difficult cannulations. CONCLUSION: Paracetamol is not effective as a prophylactic analgesic for HSG. If a prophylactic

    This study was designed to: (i) evaluate the effect of amnioinfusion on the latency period in patients with oligohydramnios for preterm premature rupture of membranes, and (ii) to investigate the relationship between changes in the amniotic fluid index and fetal heart rate short-term variability by computerized Hewlett-Packard cardiotocography, longitudinally estimated before and after prophylactic amnioinfusion. All singleton pregnancies with prolonged premature rupture of membranes after 25 weeks of gestation and seen at the Institute of Obstetrics and Gynecology, University of Ancona (Italy), between January 1994 and June 1995 were included in the study. Transabdominal amnioinfusion with 150-350 ml warmed normal saline (25-50 ml/min) was performed at weekly intervals. Amniotic fluid volume was assessed ultrasonographically by means of the four-quadrant technique on a weekly basis before and after each amnioinfusion, as well as the short-term variability by a Hewlett-Packard computerized cardiotocographic system. 18 women were enrolled and underwent prophylactic transabdominal amnioinfusion at weekly intervals until delivery. Eighteen controls, who did not undergo prophylactic amnioinfusion, were recruited from our 1992-1993 series and included in the study. The median interval between premature rupture of membranes and delivery was 3.0 weeks (range 1-8 weeks), with an average delivery age of 33.0 weeks (range 27-36 weeks). The latency period was significantly longer in patients who underwent prophylactic amnioinfusion (mean +/- SD, 4.1 +/- 1.7 weeks) than in controls(1.7 +/- 1.0 weeks; p amnioinfusion. A direct relationship was observed between the amniotic fluid index and short-term variability (linear regression analysis r = 0.54, p = 0.04). The mean values of fetal movements recorded by computerized tomography during the 20 min of observation significantly increased after amnioinfusion in comparison with those before it (2.6 +/- 0.9 and 0.9 +/- 0

    International guidelines recommend the use of a prophylactic antibiotic before the peritoneal dialysis (PD) catheter can be inserted. The main objective of this study was to assess whether this practice is associated with a lower risk of early peritonitis and to estimate the magnitude of the centre effect. A retrospective, multi-centric study was conducted, in which data from the French Language Peritoneal Dialysis Registry was analysed. Patients were separated into 2 groups based on whether or not prophylactic antibiotics were used prior to catheter placement. Out of the 2,014 patients who had a PD catheter placed between February 1, 2012 and December 31, 2014, 1,105 were given a prophylactic antibiotic. In a classical logit model, the use of prophylactic antibiotics was found to protect the individual against the risk of early peritonitis (OR 0.67, 95% CI 0.49-0.92). However, this association lost significance in a mixed logistic regression model with centre as a random effect: OR 0.73 (95% CI 0.48-1.09). Covariates associated with the risk of developing early peritonitis were age over 65: OR 0.73 (95% CI 0.39-0.85), body mass index over 35 kg/m2: OR 1.99 (95% CI 1.13-3.47), transfer to PD due to graft failure: OR 2.24 (95% CI 1.22-4.11), assisted PD: OR 1.96 (95% CI 1.31-2.93), and the use of the Moncrief technique: OR 3.07 (95% CI 1.85-5.11). There is a beneficial effect of prophylactic antibiotic used prior to peritoneal catheter placement, on the occurence of early peritonitis. However, the beneficial effect could be masked by a centre effect. © 2016 S. Karger AG, Basel.

    Clostridium difficile infection (CDI) is a common complication to antibiotic use. Saccharomyces boulardii has shown effect as a prophylactic agent. We aimed to evaluate the efficacy of S. boulardii in preventing CDI in unselected hospitalized patients treated with antibiotics. We conducted a 1 year...... controlled prospective intervention study aiming to prescribe Sacchaflor (S. boulardii 5 × 109, Pharmaforce ApS) twice daily to hospitalized patients treated with antibiotics. Comparable departments from three other hospitals in our region were included as controls. All occurrences of CDI in patients...... receiving antibiotics were reported and compared to a baseline period defined as 2 years prior to intervention. Results were analyzed using run chart tests for non-random variation in CDI rates. In addition, odds ratios for CDI were calculated. S. boulardii compliance reached 44% at the intervention...

    A prospective study, including 60 patients with vaginal discharge has been made at Maternity hospital "Majchin dom"--Sofia for the period November 2006- February 2007. In 32 patients no causative agent has been revealed. They have been counseled to use Yin Care--vaginal lotion for 3 months in prophylactic concentration. 88.4% reported for diminished discharge. No adverse effects have been observed. In 11 patients suffering from bacterial vaginitis, caused by S. Epidermidis, S. Aureus, Enterococcus and E. Coli cure was achieved in 72.7% of cases. 17 women with Candida vaginitis have been included in the study. After standard antifungal treatment, 8 of them continued therapy with Yin Care. Recurrence of disease has been observed in only one case, while in the group treated with antifungal medication only recurrence has been observed in 2 cases.

  10. Guidelines on the use of stable iodine as a prophylactic measure during nuclear emergencies

    International Nuclear Information System (INIS)

    1996-01-01

    Among the fission products that may be released in a power reactor accident the radioiodines are unique in that the dose received by persons exposed by inhalation of radioiodines in the gaseous plume may be substantially reduced. GMA-9 provides guidance on the medical aspects of the use of stable iodine compounds as a prophylactic measure in the event of a nuclear accident. A review of the physiologic basis for the use of stable iodine as a prophylatic measure and the effects of radiation on the thyroid gland are provided. Logistic factors that must be considered to provide the optimum level of radiological protection and medical safety are also addressed. Due to the delay in publishing the French version of this report, some sections of this report have been updated to reflect current practices.71 refs., 6 tabs., 2 figs

    Posterior epistaxis is a frequent emergency, and the key to efficient management is identification of the bleeding point. We performed a retrospective study of 318 patients with posterior epistaxis treated with endoscopic bipolar electrocautery during a 4-year period. Distribution of the bleeding sites was recorded. Patients with no definite bleeding sites in the first operation were assigned to Group A (n = 39) and Group B (n = 34). Patients in Group A were only observed in the ward. Patients in Group B were given prophylactic electrocoagulation at the common bleeding points. Of the 318 patients, bleeding sites were successfully identified and coagulated in 263 patients. All of them were located posteriorly, with 166 on the lateral nasal wall, 86 on the septum, and 11 on the anterior face of the sphenoid sinus. The rebleeding rate of Group B (8.8%) was lower than that of Group A (38.5%) (p < 0.01).

    Inactivating mutations in the CDH1 (E-cadherin) gene are the predisposing cause of gastric cancer in most families with hereditary diffuse gastric cancer (HDGC). The lifetime risk of cancer in mutation positive members is more than 80 % and prophylactic total gastrectomy is recommended. Not all...... mutations in the CDH1 gene are however pathogenic and it is important to classify mutations before this major operation is performed. Probands from two Danish families with gastric cancer and a history suggesting HDGC were screened for CDH1 gene mutations. Two novel CDH1 gene mutations were identified....... Hospital stay was 6-8 days and there were no complications. Small foci of diffuse gastric cancer were found in all patients-intramucosal in six and advanced in one. Preoperative endoscopic biopsies had revealed a microscopic cancer focus in two of the patients. Our data confirmed the pathogenic nature...

    We have examined the value of prophylactic epilepsy surgery in diseases leading to intractable epilepsy. We reviewed 11 glioneuronal tumors (GNT) including gangliogliomas and dysembryoplastic neuroepithelial tumors, 11 cortical dysplasia (CD), and 33 cavernous angiomas (CA) diagnosed with MRI between the years 2000 and 2008 at the Department of Neurosurgery of Juntendo University in this study. We analyzed retrospectively the followings. Age of seizure onset and seizure severity. Region of each disease leading to intractable epilepsy. Seizure outcome after the surgery. Surgical morbidity. Ages of seizure onset of GNT, CD, and CA were 21.0±12.1, 1.3±7.5, 24.8±18.1 years, respectively. 81.8% of CD and GNT were intractable, however CA progresses to intractable epilepsy in 48.5%. The 66.7% of GNT with intractable seizures located in the mesial temporal lobe and 66.7% of CD had entra-temporal location. CA located in the mesial temporal lobe progressed to intractable epilepsy in 80%. Seizure free ratios of GNT, CD, and CA were 87.5%, 50.0%, 81.3%, respectively. In CDs where was impossible to carry out complete resection resulted in residual seizures. Neurological sequelae after surgery were observed in 3 cases. Morbidity ratios of motor weakness, speech difficulty, and memory disturbances are 4.6%, 4.6%, 2.3%, respectively. Majority of CD, GNT, and CA located in the mesial temporal lobe progress towards intractable epilepsy. Prophylactic epilepsy surgery by experienced surgeon with low complication rates can be an acceptable alternative for these pathological conditions. Seizure outcome of surgery for CD does not reach the success rates of those in GNT and CA. The cause of the unfavorable result in CD is the inapplicability to eloquent areas. Aggressive early surgery for CD may improve outcome considering neuronal plasticity of childhood. (author)

    Prophylactic continuous positive airway pressure (CPAP) can prevent pulmonary adverse events following upper abdominal surgeries. The present meta-regression evaluates and quantifies the effect of degree/duration of (CPAP) on the incidence of postoperative pulmonary events. Medical databases were searched for randomized controlled trials involving adult patients, comparing the outcome in those receiving prophylactic postoperative CPAP versus no CPAP, undergoing high-risk abdominal surgeries. Our meta-analysis evaluated the relationship between the postoperative pulmonary complications and the use of CPAP. Furthermore, meta-regression was used to quantify the effect of cumulative duration and degree of CPAP on the measured outcomes. Seventy-three potentially relevant studies were identified, of which 11 had appropriate data, allowing us to compare a total of 362 and 363 patients in CPAP and control groups, respectively. Qualitatively, Odds ratio for CPAP showed protective effect for pneumonia [0.39 (0.19-0.78)], atelectasis [0.51 (0.32-0.80)] and pulmonary complications [0.37 (0.24-0.56)] with zero heterogeneity. For prevention of pulmonary complications, odds ratio was better for continuous than intermittent CPAP. Meta-regression demonstrated a positive correlation between the degree of CPAP and the incidence of pneumonia with a regression coefficient of +0.61 (95 % CI 0.02-1.21, P = 0.048, τ (2) = 0.078, r (2) = 7.87 %). Overall, adverse effects were similar with or without the use of CPAP. Prophylactic postoperative use of continuous CPAP significantly reduces the incidence of postoperative pneumonia, atelectasis and pulmonary complications in patients undergoing high-risk abdominal surgeries. Quantitatively, increasing the CPAP levels does not necessarily enhance the protective effect against pneumonia. Instead, protective effect diminishes with increasing degree of CPAP.

    To characterize the short- and long-term outcome (>12 months), complications, and owner satisfaction following prophylactic laparoscopic-assisted gastropexy (LAG) in dogs. Retrospective study. Client-owned dogs (n = 49). Dogs that underwent prophylactic LAG at 2 veterinary academic hospitals were studied. Surgical time, anesthesia time, concurrent intra- and extra-abdominal procedures, and intraoperative and postoperative complications were recorded following review of medical records. Veterinarian and/or owner follow-up was obtained to determine outcome and satisfaction with LAG. Five of 49 dogs (10%) experienced complications related to abdominal access during LAG. Four percent (2/49) of dogs experienced an intraoperative complication. Follow-up information was available for 89% of dogs (44/49). Four dogs died of causes unrelated to LAG or gastric dilatation volvulus (GDV) in the follow-up period. Two dogs experienced major postoperative complications requiring additional veterinary intervention. Thirty percent (13 dogs) experienced a minor postoperative self-limiting wound-related complication. Median follow-up time was 698 days (range, 411-1825). No dogs experienced GDV. One hundred percent of dog owners were satisfied with LAG, would repeat the procedure in a future pet, and would recommend the procedure to a friend or family member. LAG was an effective procedure for prevention of GDV and was associated with high client satisfaction in this cohort of dogs. A moderate rate of postoperative wound complications occurred that were minor and self-limiting in nature. © Copyright 2016 by The American College of Veterinary Surgeons.

    Full Text Available Abstract Background Preterm prelabor rupture of membrane (PPROM causes maternal and neonatal complications. Prophylactic antiobiotics were used in the management of PPROM. The objectives of this retrospective study were to compare clinical course and outcome of PPROM managed expectantly with prophylactic antibiotics and antenatal corticosteroids with those without prophylactic antibiotics and antenatal corticosteroids. Results A total of 170 cases of singleton pregnant women with gestational age between 28–34 weeks suffering from PROM during January 1998 to December 2009 were included; 119 cases received prophylactic antibiotics and antenatal corticosteroids while 51 cases did not received prophylactic antibiotics and antenatal corticosteroids. Median latency period in the study group was significantly longer than in the control group (89.8 vs. 24.3 hours, P  Conclusions Latency period of PPROM after using prophylactic antibiotics and antenatal corticosteroids increased while neonatal infectious morbidity was low. But maternal infectious morbidity was not increased. This retrospective study confirms the benefit of prophylactic antibiotics and antenatal corticosteroids in management of PPROM.

    There are several Cochrane systematic reviews looking at postpartum haemorrhage (PPH) prophylaxis in the third stage of labour and another Cochrane review investigating the timing of prophylactic uterotonics in the third stage of labour (i.e. before or after delivery of the placenta). There are, however, no Cochrane reviews looking at the use of interventions given purely after delivery of the placenta. Ergometrine or methylergometrine are used for the prevention of PPH in the postpartum period (the period after delivery of the infant) after delivery of the placenta in some countries. There are, furthermore, no Cochrane reviews that have so far considered herbal therapies or homeopathic remedies for the prevention of PPH after delivery of the placenta. To assess the effectiveness of available prophylactic interventions for PPH including prophylactic use of ergotamine, ergometrine, methylergometrine, herbal therapies, and homeopathic remedies, administered after delivery of the placenta, compared with no uterotonic agents as well as with different routes of administration for prevention of PPH after delivery of the placenta. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013), The Food and Drug Administration (FDA) (USA),  Medicines and Healthcare Products Regulatory Agency (MHRA) (UK), European Medicines Agency (EMA) (EU), Pharmaceuticals and Medical Devices Agency (PMDA) (Japan),  Therapeutic Goods Administration (TGA) (Australia), ClinicalTrials.gov, Current Controlled Trials, WHO International Clinical Trials Registry Platform (ICTRP), University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; Japan), Japan Pharmaceutical Information Center Clinical Trials Information (Japic-CTI; Japan), Japan Medical Association Clinical Trial Registration (JMACCT CTR; Japan) (all on 30 April 2013) and reference lists of retrieved studies All randomised or quasi-randomised controlled trials comparing prophylactic

    Purpose/Objective: To determine the effect of post-operative radiation on the incidence of heterotopic ossification following traumatic acetabular fracture. Materials and Methods: A retrospective analysis was performed of the medical records and radiographs of all patients who received prophylactic radiotherapy to prevent heterotopic ossification. These results were compared to a similar group of patients receiving no prophylactic radiotherapy following traumatic acetabular fracture. Between 1987 and 1994, sixty-six patients received prophylactic radiotherapy to prevent heterotopic ossification. Results: Thirty-six patients (55%) received radiotherapy following operative repair of a traumatic acetabular fracture (median follow-up: 210 days). Three dose schedules were utilized: (28(36)) (77.8%) received 700 cGy/1 fx, (2(36)) (5.5%) 800 cGy/1 fx, and (6(36)) (16.7%) 1000 cGy/5 fxs. These patients were retrospectively compared with thirty-four patients who received similar operative management of traumatic acetabular fractures without post-operative radiotherapy (median follow-up: 378 days). Of the patients with heterotopic ossification, 96% developed it within 180 days. Complications and delayed wound healing rates were not significantly different in patients treated with or without post-operative radiotherapy, 6.4% and 6.3% respectively (p=0.49). The incidence of heterotopic ossification at last follow-up in patients treated with and without post-operative radiotherapy was (5(36)) (13.9%) and (19(34)) (55.9%), respectively (p=0.000332). For all patients, type of surgical approach was associated with development of heterotopic ossification: posterior, (7(38)) (18.4%), ilio-inguinal (1(3)) (33.3%), tri-radiate (13(19)) (68.4%), p=.000511. In patients receiving post-operative radiotherapy, variables associated with heterotopic ossification included dose (p=.00962), injury-to-radiation interval (p=.0038), and surgery-to-radiation interval (p=.0238).

    Identify factors associated with the prophylactic prescription of a bowel regimen with an inpatient opioid prescription. This was a retrospective cohort study from June 1, 2013, to October 31, 2014 of pediatric inpatients prescribed an oral or intravenous opioid on the general medical/surgical floors. We identified patients with or without a prophylactic prescription of a bowel regimen. We obtained patient demographics, prescriber training level and service and used multivariate logistic regression to analyze the factors associated with prophylactic bowel regimen and opioid prescription. Of the 6682 encounters that met study criteria, only 966 (14.5%) encounters had prophylactic prescriptions. Patient factors associated with prophylactic prescription include increasing age (per year; odds ratio [OR] = 1.06, 95% confidence interval [CI] 1.05-1.07) and sickle cell diagnosis (OR = 3.19, 95% CI 2.08-4.91). Medication factors associated with prophylactic prescription include a scheduled opioid prescription (OR = 1.75, 95% CI 1.46-2.1) and a prescription for oxycodone (OR = 3.59, 95% CI 2.57-5.00) or morphine (OR = 1.84, 95% CI 1.39-2.44), compared with acetaminophen-hydrocodone. Compared with medical providers, surgeons were less likely (OR = 0.43, 95% CI 0.35-0.53) and pain service providers were more likely to prescribe a prophylactic bowel regimen (OR = 4.12, 95% CI 3.13-5.43). More than 85% of inpatient opioid prescriptions did not receive a prophylactic bowel regimen. Future research should examine factors (eg, clinical decision support tools) to increase prophylactic prescription of bowel regimens with opioids for populations found to have lower rates.

    : Severe hereditary factor VII deficiency is a rare bleeding disorder and may be associated with a severe bleeding phenotype. We describe a pregnancy in a 33-year-old woman with compound heterozygous factor VII deficiency and a history of severe menorrhagia and mucocutaneous bleedings. After discontinuation of contraceptives, menstruation was covered with recombinant activated factor VII (rFVIIa), and during pregnancy, rFVIIa had to be administered in first trimester in doses ranging from 15 to 90 μg/kg per day because of recurrent retroplacental hematomas and vaginal bleedings. Thrombin generation was measured in first trimester at different doses of rFVIIa and showed an increase in lag time when doses of less than 30 μg/kg/day were administered, whereas time to thrombin peak and peak thrombin were not influenced. A low-dose rFVIIa prophylactic treatment of 15 μg/kg every other day in the late second and in the third trimester was sufficient to allow a successful childbirth in this patient with severe factor VII deficiency.

    BACKGROUND: Prophylactic cerebral irradiation (PCI) is a standard treatment for all small cell lung cancer (SCLC) patients with response to chemotherapy. The aims of this study were: to evaluate patients undergoing PCI with regard to cerebral recurrence rate, site of recurrence, and overall...... retrospectively with regard to disease stage, treatment, date of PCI, steroid dose during PCI, toxicity, time to recurrence, site of recurrence and time of death. The median follow up time was 16.6months (range 3-54months). RESULTS: Of the 118 patients undergoing PCI, 74 had limited disease (LD-SCLC) and 44 had...... extensive disease (ED-SCLC). The median age was 65years (range 46-80years). The median overall survival of all patients from the time of diagnosis was 16.0months (CI 95% 13.0-19.0), in LD-SCLC it was 24.0months (CI 95% 19.6-28.3), and in ED-SCLC it was 12.0months (CI 95% 9.6-14.4). Twenty-one patients (17...

    Purpose: To report outcomes of patients with localized intracranial germinoma treated with low-dose craniospinal irradiation (CSI) followed by a boost to the ventricular system and primary site. Methods and Materials: Thirty-one patients had pathologically confirmed intracranial germinoma and no spine metastases. Low-dose CSI was administered in 29 patients: usually 21 Gy of CSI, 9.0 Gy of ventricular boost, and a 19.5-Gy tumor boost, all at 1.5 Gy per fraction. Our neuroradiologist recorded three-dimensional tumor size on magnetic resonance images before, during, and after radiotherapy. Results: With a median follow-up of 7.0 years, 29 of 31 patients (94%) are disease free. One failure had nongerminomatous histology; the initial diagnosis was a sampling error. Of 3 patients who did not receive CSI, 1 died. No patient developed myelopathy, visual deficits, dementia, or skeletal growth problems. In locally controlled patients, tumor response according to magnetic resonance scan was nearly complete within 6 months after radiotherapy. Conclusions: Radiotherapy alone with low-dose prophylactic CSI cures almost all patients with localized intracranial germinoma. Complications are rare when the daily dose of radiotherapy is limited to 1.5 Gy and the total CSI dose to 21 Gy. Patients without a near-complete response to radiotherapy should undergo resection to rule out a nongerminomatous element

    Recruitment of volunteers is one of the main challenges in clinical trial management, and there is little information about recruitment barriers for preventative vaccine trials. We investigated both the recruitment barriers and recruitment strategies for preventive vaccine trials in Belgium. A 10 min survey was used as well as interviews of staff at all clinical trial sites in Belgium that regularly perform vaccine trials. We observed that there are successful recruitment strategies and few recruitment issues for trials involving healthy adults and those over 65 years old. However, challenges face the recruitment of paediatric populations, pregnant women, patients and the very elderly (over 85 years old). From these results, we identified three priority areas to increase recruitment for prophylactic vaccine trials in Belgium. These are: the lack of public knowledge about infectious diseases; the lack of resources of healthcare professionals to take part in clinical trials; and the burden to potential volunteers to take part in a trial. These were discussed with stakeholders and solutions were proposed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The prophylactic treatment of the CNS was conducted by cobalt teletherapy of the cranium and by intrathecal application of MTX after the induction of primary remission in 70 children with acute leukemia throughout 5 years up to the end of 1978. The method of the combined radio- and chemoprophylaxis of the CNS was being changed during the years, especially as far as the radiation dose for the cranium was concerned. A detailed analysis made in a group of 59 children with the minimum interval of 18 months from the beginning of the treatment showed the best results after the application of a dose of 24 Gy/3 weeks. Following this procedure the relapse of leukemia in the CNS occurred in 9% only, whereas on the application of doses of 20 Gy and lower it occurred in 35 to 40%. On the whole 24 out of 59 children, i.e. 41%, are surviving, 35 children, i.e. 59%, died. Mostly complete, but only temporary, epilation was an invariable consequence of the irradiation of the cranium. The somnolence syndrome was only sporadically observed. It cannot be excluded, however, that some of its forms in patients discharged from hospital escaped attention. No case was recorded of serious impairment of the CNS of the leukoencephalopathic type. Up to now the psychomotor, intellectual and emotional development of the surviving children has been normal. (author)

    Full Text Available Background and objective: Post Operative endophthalmitis is rare but devastating complication in ocular surgery. The present study determined the efficacy of intracameral vancomycin after phaco-emusification cataract surgery to prevent endophthalmitis. Method: A total of 768 cases who had undergone phaco-emusification cataract surgery were included in the study. Every alternate patient received 0.5 ml injection of vancomycin (1mg in 0.1 ml in the anterior chamber after completion of phaco-emulcification and formation of anterior chamber. All the patients were examined for symptoms and signs of bacterial endophthalmitis at 24 hrs, 7 days, 15 days and subsequently at 1, 3 and 6 months following surgery. Results: No endophthalmitis case was recorded at any time period during 6 month follow up in either group. However, significantly higher number of cases in vancomycin group had cells in anterior chamber and disturbances in visual acuity at day 15 following surgery. Conclusion: Vancomycin did not have any prophylactic role in preventing endophthalmitis. Proper aseptic measures are important to prevent any infection in ocular surgery.

    Full Text Available Acute appendicitis remains the most common surgical emergency. Laparoscopy has gained increasing favor as a method of both investigating right iliac fossa pain and treating the finding of appendicitis. A question arises: what to do with an apparent healthy appendix discovered during laparoscopic surgery for other pathology. We present a case of unilateral hydroureteronephrosis complicated with rupture of the renal pelvis, due to gangrenous appendicitis with abscess of the right iliopsoas muscle and periappendicular inflammation in a 67-year-old woman, who underwent laparoscopic right annessiectomy for right ovarian cyst few years earlier, in which a healthy appendix was left inside. There is a lack of consensus in the literature about what to do with a normal appendix. The main argument for removing an apparently normal appendix is that endoluminal appendicitis may not be recognized during surgery, leading to concern that an abnormal appendix is left in place. Because of a lack of evidence from randomized trials, it remains unclear whether the benefits of routine elective coincidental appendectomy outweigh the costs and risks of morbidity associated with this prophylactic procedure. Nevertheless, it appears, from limited data, that women aged 35 years and under benefit most from elective coincidental appendectomy.

    The consistency of the classification of prophylactic antiradiation drugs have been given consideration as history of their discovery, theory of the radioprotection mechanisms and their use in applied medicine. Prophylactic drugs consists of radioprotectors with short-term of long-term action, drugs stimulating radioresistance, the ones suppressing symptoms of primary radiation reaction, the ones of early detoxication, the ones for adsorption and elimination of radionuclides from an organism [ru

    Full Text Available Metastatic involvement of central lymph nodes in patients with papillary thyroid cancer (PTC is very common. However, prophylactic central lymph nodes dissection additionally to thyroidectomy does not significantly affect disease-free and overall survival of PTC patients. Meanwhile its routine conduction is tangibly increase postsurgical complications. From efficacy/safety point of view prophylactic central lymph nodes dissection couldn't be recommended as substantiated in all PTC patients.

    Parastomal hernia is a very common complication after colostomy, especially end-colostomy. It is unclear whether prophylactic placement of mesh at the time of stoma formation could prevent parastomal hernia formation after surgery for rectal cancer. A systematic review and meta-analysis were conducted to evaluate the efficacy of prophylactic mesh in end-colostomy construction. PubMed, Embase, and the Cochrane Library were searched, covering records entered from their inception to September 2015. Randomized controlled trials (RCTs) comparing stoma with mesh to stoma without mesh after surgery for rectal cancer were included. The primary outcome was the incidence of parastomal hernia. Pooled risk ratios (RR) with 95 % confidence intervals (CI) were obtained using random effects models. Six RCTs containing 309 patients were included. Parastomal hernia occurred in 24.4 % (38 of 156) of patients with mesh and 50.3 % (77 of 153) of patients without mesh. Meta-analysis showed a lower incidence of parastomal hernia (RR, 0.42; 95 % CI 0.22-0.82) and reoperation related to parastomal hernia (RR, 0.23; 95 % CI 0.06-0.89) in patients with mesh. Stoma-related morbidity was similar between mesh group and non-mesh group (RR, 0.65; 95 % CI 0.33-1.30). Prophylactic placement of a mesh at the time of a stoma formation seems to be associated with a significant reduction in the incidence of parastomal hernia and reoperation related to parastomal hernia after surgery for rectal cancer, but not the rate of stoma-related morbidity. However, the results should be interpreted with caution because of the heterogeneity among the studies.

    Prophylactic or therapeutic immunomodulation is an antigen-independent strategy that induces nonspecific immune system activation, thereby enhancing host defense to disease. In this study, we investigated the effect of prophylactic immunomodulation on the outcome of influenza virus infection using three bacterially derived immune-enhancing agents known for promoting distinct immunological profiles. BALB/c mice were treated nasally with either cholera toxin (CT), a mutant form of the CT-related Escherichia coli heat-labile enterotoxin designated LT(R192G), or CpG oligodeoxynucleotide. Mice were subsequently challenged with a lethal dose of influenza A/PR/8/34 virus 24 h after the last immunomodulation treatment and either monitored for survival or sacrificed postchallenge for viral and immunological analysis. Treatment with the three immunomodulators prevented or delayed mortality and weight loss, but only CT and LT(R192G) significantly reduced initial lung viral loads as measured by plaque assay. Analysis performed 4 days postinfection indicated that prophylactic treatments with CT, LT(R192G), or CpG resulted in significantly increased numbers of CD4 T cells, B cells, and dendritic cells and altered costimulatory marker expression in the airways of infected mice, coinciding with reduced expression of pulmonary chemokines and the appearance of inducible bronchus-associated lymphoid tissue-like structures in the lungs. Collectively, these results suggest that, despite different immunomodulatory mechanisms, CT, LT(R192G), and CpG induce an initial inflammatory process and enhance the immune response to primary influenza virus challenge while preventing potentially damaging chemokine expression. These studies provide insight into the immunological parameters and immune modulation strategies that have the potential to enhance the nonspecific host response to influenza virus infection.

    The role of olanzapine added to a dopamine antagonist and benzodiazepine for the treatment of refractory chemotherapy-induced nausea and vomiting (CINV) is incompletely characterized in all levels of chemotherapy emetogenicity. This retrospective study evaluated the efficacy of the addition of olanzapine in adults experiencing refractory CINV stratified by chemotherapy emetogenicity. Thirty-three adults who experienced CINV refractory to guideline-recommended prophylaxis and breakthrough antiemetics (dopamine antagonists and benzodiazepines) and received at least one dose of olanzapine 5-10 mg per os were evaluated. Failure was defined as >5 emesis events in 24 h or more than 10 cumulative doses of rescue antiemetics following first olanzapine dose per treatment cycle. Post hoc analyses investigated variables impacting olanzapine efficacy. The addition of olanzapine demonstrated an overall success rate of 70 %. This success rate did not differ between chemotherapy regimens of high versus low-to-moderate emetogenicity (p = 0.79), prophylaxis with serotonin antagonist plus corticosteroid and aprepitant versus serotonin antagonist alone (p = 0.77), or age over 50 versus ≤50 years (p > 0.99). A trend toward greater benefit was seen in women (p = 0.08). The addition of olanzapine to a dopamine antagonist and benzodiazepine demonstrated high efficacy rates for refractory CINV irrespective of chemotherapy emetogenicity. The high success rates among all groups suggests that incomplete resolution of CINV with prophylactic serotonin antagonists and breakthrough dopamine antagonists plus benzodiazepine may benefit from the addition of olanzapine regardless of gender, degree of chemotherapy emetogenicity, number of prophylactic antiemetics, or age. The trend toward greater control of emesis in women merits further investigation.

    STUDY OBJECTIVES: To compare the prophylactic antiemetic efficacy of the combination of ondansetron and droperidol with that of droperidol alone in patients undergoing elective laparoscopic cholecystectomy. DESIGN: Randomized, double-blind controlled trial. University affiliated teaching hospital after induction of standardized general anesthesia. PATIENTS: 64 ASA physical status I or II patients aged 18 to 80 years, undergoing elective laparoscopic cholecystectomy. INTERVENTION: Following induction of general anesthesia, patients received either droperidol 1.25 mg intravenously (IV; n = 30; Group D) or the combination of droperidol 1.25 mg IV and ondansetron 4 mg IV (n = 34; Group D+O). MEASUREMENTS: Number and severity of nausea episodes, number of emetic episodes, total analgesic consumption, and rescue antiemetic administration were assessed at 1, 3, and 24 hours after admission to the recovery room. Data were analyzed using Fisher\\'s Exact test and unpaired Student\\'s t-test; a p-value <0.05 was considered significant. RESULTS: The proportions of patients who experienced nausea (70% and 53% for D and D+O groups, respectively) and vomiting (30% and 19% for D and D+O groups, respectively) were similar in the two groups. The frequency of moderate and severe nausea (requiring administration of antiemetic) was less in group D + O (7%) compared with group D (19%; p < 0.05). CONCLUSIONS: Patients who received the combination of droperidol and ondansetron experienced less severe nausea compared with patients who received droperidol alone.

    Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in thrombocytopenic patients with bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004 and updated in 2012 that addressed four separate questions: therapeutic-only versus prophylactic platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. We have now split this review into four smaller reviews looking at these questions individually; this review is the first part of the original review. Objectives To determine whether a therapeutic-only platelet transfusion policy (platelet transfusions given when patient bleeds) is as effective and safe as a prophylactic platelet transfusion policy (platelet transfusions given to prevent bleeding, usually when the platelet count falls below a given trigger level) in patients with haematological disorders undergoing myelosuppressive chemotherapy or stem cell transplantation. Search methods We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (Cochrane Library 2015, Issue 6), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950) and ongoing trial databases to 23 July 2015. Selection criteria RCTs involving transfusions of platelet concentrates prepared either from individual units of whole blood or by apheresis, and given to prevent or treat bleeding in patients with malignant haematological disorders receiving myelosuppressive chemotherapy or undergoing HSCT. Data collection and analysis We used standard methodological procedures

    The combined effects of physostigmine and procyclidine (antagonizing muscarinic, nicotinic, and NMDA receptors) were tested against various doses of soman. Physostigmine (0.1 mg/kg) in combination with procyclidine doses of 1, 3, or 6 mg/kg effectively prevented the development of convulsions and hippocampally monitored seizures when the doses of soman were 1.3, 1.6, or 2 x LD50, respectively. Results from [ 3 H]MK-801-binding experiments showed that procyclidine inhibits the phencyclidine site at the NMDA receptor in a concentration-dependent manner. Physostigmine (0.1 mg/kg) and procyclidine in a dose of 1 mg/kg did not prevent convulsions or seizures when the soman dose was 1.6 x LD50. Subsequent treatment with scopolamine in doses of 0.5 or 1 mg/kg immediately after (3 min) seizure onset showed that only the highest dose produced a reliable termination. When scopolamine (1 mg/kg) was given later (10 min) after onset of seizures, no effect was obtained. The sustained seizures were subsequently treated with diazepam (10 mg/kg) and pentobarbital (30 mg/kg) and finally terminated 25 min after onset. In rats given inadequate prophylaxis, both modified convulsions and seizures were seen. It is suggested that moderate doses of prophylactics should be preferred to avoid adverse effects on cognitive functions because insufficient prophylaxis can be compensated for by adjunct treatment

    Purpose: To examine whether cerebrospinal fluid biomarkers for neuroaxonal damage, neuroglial activation, and amyloid β–related processes could characterize the neurochemical response to cranial radiation. Methods and Materials: Before prophylactic cranial irradiation (PCI) of patients with small cell lung cancer, each patient underwent magnetic resonance imaging of the brain, lumbar puncture, and Mini-Mental State Examination of cognitive function. These examinations were repeated at approximately 3 and 12 months after radiation. Results: The major findings were as follows. (1) Cerebrospinal fluid markers for neuronal and neuroglial injury were elevated during the subacute phase after PCI. Neurofilament and T-tau increased 120% and 50%, respectively, after PCI (P<.05). The same was seen for the neuroglial markers YKL-40 and glial fibrillary acidic protein, which increased 144% and 106%, respectively, after PCI (P<.05). (2) The levels of secreted amyloid precursor protein-α and -β were reduced 44% and 46%, respectively, 3 months after PCI, and the levels continued to decrease as long as 1 year after treatment (P<.05). (3) Mini-Mental State Examination did not reveal any cognitive decline, indicating that a more sensitive test should be used in future studies. Conclusion: In conclusion, we were able to detect radiation therapy–induced changes in several markers reflecting neuronal injury, inflammatory/astroglial activation, and altered amyloid precursor protein/amyloid β metabolism, despite the low number of patients and quite moderate radiation doses (20-30 Gy). These changes are hypothesis generating and could potentially be used to assess the individual risk of developing long-term symptoms of chronic encephalopathy after PCI. This has to be evaluated in large studies with extended clinical follow-up and more detailed neurocognitive assessments.

    In Poland cardiovascular diseases (CVD), classified as work-related diseases, are responsible for 25% of disability and cause 50% of all deaths, including 26.9% of deaths in people aged under 65 years. The aim of the study was to analyze employee expectations regarding CVD- oriented prophylactic activities in the selected enterprise. A questionnaire, developed for this study, consists of: socio-demographic data, job characteristics, occupational factors, and questions about the respondents' expectations concerning the prevention program. The study group comprised 407 multi-profile company employees aged (mean) 46.7 years (standard deviation (SD) = 9.1), including 330 men (81.1%), mean age = 46.9 (SD = 9.2) and 77 women (18.9%), mean age = 45.9 (SD = 8.2) The study was performed using the method of auditorium survey. Employees declared the need for actions related to physical activity: use of gym, swimming pool, tennis (56.5%), smoking habits - education sessions on quitting smoking (24.6%). A few people were interested in activities related to healthy diet. According to the majority of the study group, the scope of preventive examinations should be expanded. Based on our own findings and literature data CVD- -oriented preventive program, addressed to the analyzed enterprise was prepared. The program will be presented in another paper. The results showed significant quantitative and qualitative differences in the classic and occupational CVD risk factors between men and women, as well as in preferences for participation in prevention programs. Therefore, gender differences should be taken into account when planning prevention programs. Med Pr 2017;68(6):757-769.

    Purpose: To examine whether cerebrospinal fluid biomarkers for neuroaxonal damage, neuroglial activation, and amyloid β–related processes could characterize the neurochemical response to cranial radiation. Methods and Materials: Before prophylactic cranial irradiation (PCI) of patients with small cell lung cancer, each patient underwent magnetic resonance imaging of the brain, lumbar puncture, and Mini-Mental State Examination of cognitive function. These examinations were repeated at approximately 3 and 12 months after radiation. Results: The major findings were as follows. (1) Cerebrospinal fluid markers for neuronal and neuroglial injury were elevated during the subacute phase after PCI. Neurofilament and T-tau increased 120% and 50%, respectively, after PCI (P<.05). The same was seen for the neuroglial markers YKL-40 and glial fibrillary acidic protein, which increased 144% and 106%, respectively, after PCI (P<.05). (2) The levels of secreted amyloid precursor protein-α and -β were reduced 44% and 46%, respectively, 3 months after PCI, and the levels continued to decrease as long as 1 year after treatment (P<.05). (3) Mini-Mental State Examination did not reveal any cognitive decline, indicating that a more sensitive test should be used in future studies. Conclusion: In conclusion, we were able to detect radiation therapy–induced changes in several markers reflecting neuronal injury, inflammatory/astroglial activation, and altered amyloid precursor protein/amyloid β metabolism, despite the low number of patients and quite moderate radiation doses (20-30 Gy). These changes are hypothesis generating and could potentially be used to assess the individual risk of developing long-term symptoms of chronic encephalopathy after PCI.

    Prophylactic mastectomy is an effective risk-reducing option in women with hereditary increased risk of breast cancer. It may be combined with immediate reconstruction, with the intention of improving aesthetic outcome and health-related quality of life. Sixty-one women underwent prophylactic mastectomy and immediate breast reconstruction in Malmö, Sweden, between 1995 and 2003. Forty women underwent bilateral prophylactic mastectomy and immediate reconstruction. Ten of these had a previous breast cancer diagnosis. Twenty-one women underwent contralateral prophylactic mastectomy and immediate reconstruction after a previous breast cancer. Fifty-four of the women (89%) were evaluated clinically for aesthetic results and complications. Patient satisfaction and quality of life were evaluated with one study-specific and two standardised health-related questionnaires administered at time of clinical follow-up. Median follow-up time was 42 months (range 7-99 months). The position of the reconstructed breasts was judged as satisfactory in 77% of breasts. Symmetry in relation to the midline was adequate in 89% of breasts. A capsular contracture grade III according to Baker and indentation tonometry was observed in 1% of breasts (1/104). The complication rate was 18% (7% early and 11% late). Secondary corrections were carried out in 11% of breasts. The study-specific questionnaire revealed a high degree of satisfaction. No woman regretted the procedure, and all women would have chosen the same type of surgery again. An age-stratified comparison of Swedish women using the Short Form 36 Health Survey Questionnaire (SF-36) questionnaire was carried out for this study. The study population scores were high, suggesting that prophylactic mastectomy and immediate reconstruction on both physical and psychological issues in this retrospective study had no negative effect. Also, the Hospital Anxiety and Depression Scale (HAD) questionnaire did not suggest any increased anxiety or

    Background Artificial cornea transplantation, keratoprosthesis, improves vision for patients at high risk of failure with human cadaveric cornea. However, post-operative infection can cause visual loss and implant extrusion in 3.2–17% of eyes. Long-term vancomycin drops are recommended following keratoprosthesis to prevent bacterial keratitis. Evidence, though, in support of this practice is poor. We investigated whether prophylactic vancomycin drops prevented bacterial keratitis in an animal keratoprosthesis model. Methodology Twenty-three rabbits were assigned either to a prophylactic group (n = 13) that received vancomycin 1.4% drops 5 times/day from keratoprosthesis implantation to sacrifice, or a non-prophylactic group (n = 10) that received no drops. All rabbits had Staphylococcus aureus inoculation into the cornea at 7–12 days post-implantation and were sacrificed at predetermined time-points. Prophylactic and non-prophylactic groups were compared with slit-lamp photography (SLP), anterior segment optical coherence tomography (AS-OCT), and histology, immunohistochemistry and bacterial quantification of excised corneas. Corneal vancomycin pharmacokinetics were studied in 8 additional rabbits. Results On day 1 post-inoculation, the median SLP score and mean±SEM AS-OCT corneal thickness (CT) were greater in the non-prophylactic than the prophylactic group (11 vs. 1, p = 0.049 and 486.9±61.2 vs. 327.4±37.1 μm, p = 0.029 respectively). On days 2 and 4, SLP scores and CT were not significantly different. Immunohistochemistry showed a greater CD11b+ve/non-CD11b+ve cell ratio in the non-prophylactic group (1.45 vs. 0.71) on day 2. Bacterial counts were not significantly different between the two groups. Corneal vancomycin concentration (2.835±0.383 μg/ml) exceeded minimum inhibitory concentration (MIC) for Staphylococcus aureus only after 16 days of vancomycin drops. Two of 3 rabbits still developed infection despite bacterial inoculation after 16 days of

Patients (n=63; aged 52.2±12.6 years; 25.4% women with frequent AF recurrences who restored sinus rhythm with propafenone, were included into the study. Paroxysmal AF was observed in 84.1% of patients, and persistent AF — in 15.9% of patients. ECG, transthoracic echocardiography , chest radiography with the calculation of cardio-thoracic index (CTI was performed at baseline. All patients received rpropafenone therapy (450–600 mg/day during 6 months after sinus rhythm conversion. ECG and 24-hours ECG monitoring were performed in 1, 3 and 6 months of the therapy. Patients with 70–100% reduction in AF recurrence rate were included into the 1-st group, and patients with <70% reduction – into the 2-nd group. Results. 92%, 88.5% and 78% of patients were included into the group 1 after 1, 3 and 6 months of follow up, respectively. AF recurrences were observed 4.5, 3.8, and 1.7 times more often in women than these in men after 1, 3 and 6 months, respectively , (p>0.05. Mean age of patients in the group 2 was significantly older than this in patients of the group 1 (p<0.05.

As a result, emergence of resistant organisms is commonplace. Antibiotic prophylaxis in surgery consists of a short antibiotic course given immediately before the procedure in order to prevent development of a surgical site infection. The basic principle of prophylaxis is to maintain effective concentrations of an antibiotic active against the commonest pathogens during the entire surgery.Materials and methods: We prospectively investigated 427 urologic surgery cases in our department between August 2008 and September 2009 (Group1. As reference cases, we retrospectively reviewed 966 patients who underwent urologic surgery between May 2004 and May 2008 (Group 2 who were administered antibiotics without any restriction. Prophylactic antibiotics such as cefazolin were administered intravenously according to our protocol. Postoperative body temperature, peripheral white blood cell counts, urinalysis, and urine culture were checked.Results: To judge perioperative infections, wound condition and general condition were evaluated in terms of surgical site infection, as well as remote infection and urinary tract infection, up to postoperative day 30. Surgical site infection was defined as the presence of swelling, tenderness, redness, or drainage of pus from the wound, superficially or deeply. Remote infection was defined as occurrence of pneumonia, sepsis, or urinary tract infection.

    The purpose of the study is to investigate the usefulness of the triplet regimen comprising aprepitant, palonosetron, and dexamethasone in patients treated with highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). Patients with lung cancer (aged 65.8 ± 8.4 years) who received carboplatin-based MEC and those treated with cisplatin-based HEC were enrolled. The antiemetic regimen for both types of chemotherapy consisted of aprepitant, palonosetron, and dexamethasone based on the May 2010 guidelines prepared by the Japan Society of Clinical Oncology. The incidence of chemotherapy-induced nausea and vomiting (CINV) and the use of salvage treatment were assessed. The primary endpoints were the percentage of patients with a complete response (CR: no nausea and no salvage treatment) during the entire study period (5 days) after chemotherapy, during the acute phase (day 1), and during the delayed phase (days 2-5). CR rates for the entire period were 86 and 71% in patients receiving carboplatin-based and cisplatin-based chemotherapy, respectively. CR rates were respectively 98 and 100% in the acute phase versus 87 and 71% in the delayed phase. Most of the patients could ingest food throughout the entire period after chemotherapy. Assessment of various risk factors for acute and delayed CINV (gender, age, prior vomiting due to antineoplastic therapy, prior experience of motion sickness, and history of drinking) revealed no significant influence of these factors on the CR rate for the entire period in patients receiving either carboplatin-based or cisplatin-based chemotherapy. The present triple therapy can be recommended for supporting both carboplatin-based and cisplatin-based chemotherapy regimens.

    In 0.1 mol L-1 HCl medium, antiemetic drugs (ATM), such as granisetron hydrochloride (GS) and tropisetron hydrochloride (TS), reacted with H3PW12O40·nH2O and formed 3:1 ion-association complex of [(ATM)3PW12O40], then self-aggregated into nanoparticles-[(ATM)3PW12O40]n with an average size of 100 nm. The reaction resulted in the enhancement of resonance Rayleigh scattering (RRS) and the absorption spectra. The increments of scattering intensity (ΔIRRS) and the change of absorbance (ΔA) were both directly proportional to the concentrations of ATM in certain ranges. Accordingly, two new RRS and spectrophotometric methods were proposed for ATM detection. The detection limits (3σ) of GS and TS were 3.2 ng mL-1 and 4.0 ng mL-1(RRS method), 112.5 ng mL-1 and 100.0 ng mL-1(spectrophotometric method). These two methods were applied to determine GS in orally disintegrating tablets and the results were in good agreement with the official method. The ground-state geometries and electronic structures of GS and TS were optimized by the hybrid density functional theory (DFT) method and the shape of [(ATM)3PW12O40]n was characterized by atomic force microscopy (AFM). Take the RRS method with higher sensitivity as an example, the reaction mechanism and the reasons for enhancement of scattering were discussed.

    Objectives: Flare-up during root canal treatment of non vital teeth is a common clinical incident. The aim of the present study was to assess the effect of prophylactic use of antibiotics to avoid flare up during root canal treatment of the teeth having asymptomatic necrotic pulp. Materials and Methods: A randomized double blind clinical trial with parallel design was conducted on 100 subjects with asymptomatic non vital teeth. They were randomly divided into two groups. The first group (50 participants) was given two gram amoxicillin one hour before the first visit of root canal treatment; the second group (50 participants) did not receive any treatment (control group). In both groups, root canal treatment was performed in two visits. The flare up was assessed by the pain visual analogue scale and based on the swelling criteria. The data were processed and analyzed using SPSS statistical software 17. A p-value of 0.05 or less was considered statistically significant. Results: A total of 80% of participants in the experimental group had flare up while 12% of participants had flare up in the control group. Prophylactic Amoxicillin had no effect on inter-appointment flare up (p > 0.05). There was no relationship between flare up and patient’s age, gender and tooth type (p > 0.05). Conclusion: Prophylactic use of Amoxicillin in asymptomatic non vital teeth before root canal treatment had no effect on the incidence of flare-up. PMID:25954695

    To test the hypothesis that prophylactic dextrose gel administered to newborn infants at risk for hypoglycemia will increase the initial blood glucose concentration after the first feeding and decrease neonatal intensive care unit (NICU) admissions for treatment of asymptomatic neonatal hypoglycemia compared with feedings alone. This quasi-experimental study allocated asymptomatic at-risk newborn infants (late preterm, birth weight 4000 g, and infants of mothers with diabetes) to receive prophylactic dextrose gel (Insta-Glucose; Valeant Pharmaceuticals North America LLC, Bridgewater, New Jersey); other at-risk infants formed the control group. After the initial feeding, the prophylactic group received dextrose gel (0.5 mL/kg) rubbed into the buccal mucosa. The blood glucose concentration was checked 30 minutes later. Initial glucose concentrations and rate of NICU admissions were compared between the prophylactic group and controls using bivariate analyses. A multivariable linear regression compared first glucose concentrations between groups, adjusting for at-risk categories and age at first glucose concentration. There were 236 subjects (72 prophylactic, 164 controls). The first glucose concentration was not different between the prophylactic and control groups in bivariate analysis (52.1 ± 17.1 vs 50.5 ± 15.3 mg/dL, P = .69) and after adjusting for covariates (P  = .18). Rates of NICU admission for treatment of transient neonatal hypoglycemia were 9.7% and 14.6%, respectively (P = .40). Prophylactic dextrose gel did not reduce transient neonatal hypoglycemia or NICU admissions for hypoglycemia. The carbohydrate concentration of Insta-Glucose (77%) may have caused a hyperinsulinemic response, or alternatively, exogenous enteral dextrose influences glucose homeostasis minimally during the first few hours when counter-regulatory mechanisms are especially active.

    The effectiveness of a single 8-Gy fraction prophylactic cranial irradiation regime was assessed in 106 patients with small-cell carcinoma of the lung. All patients had limited stage disease and received combination chemotherapy consisting of either cisplatin or carboplatin with ifosfamide, etoposide, and vincristine (VICE). Cranial irradiation was administered 48 h after the first cycle of chemotherapy and was well tolerated. Actual 2-year survival was 35% and cranial relapse occurred in 22% of those patients who achieved complete remission. This compares favourably with a cranial relapse rate of 45% incomplete remitters previously reported with the same chemotherapy regime after a minimum follow-up of 2 years where PCI was not used. Formal psychometric testing was performed retrospectively on a series of 25 long-term survivors of whom 14 were taken from this reported series. Whilst 75% of patients were impaired on at least one test with 68% performing badly in the most complex task, this was not associated with clinically detectable neurological damage and the patients did not complain of memory or concentration difficulties. In conclusion, single fraction PCI, when used with platinum based combination chemotherapy, appears to be equally effective but may be less neurotoxic than the more standard fractionated regimes

    The recent US Food and Drug Administration licensure of a prophylactic vaccine against oncogenic human papillomavirus (HPV) types 16 and 18, the first of its kind, poses unique challenges in postmarketing vaccine surveillance, especially in measuring vaccine effectiveness against biologic endpoints of HPV infection. Historically, the national system of population-based cancer registries in the US has provided high-quality data on cancer incidence and mortality for the most important biologic endpoints, namely, anogenital cancers and some oral cavity/oropharyngeal cancers. There also has been some data collection on cancer precursors; however, this activity has been inconsistent and of lower priority. Because effectiveness against HPV-associated cancers will not be measurable for several decades, strengthening and possibly expanding the capacity of registries to collect precancer data, which are earlier manifestations of infection, must be considered. Collecting type-specific data on HPV-associated precancers and cancers. While keeping in mind the current limitations of registry operations, they discuss resources that may be needed to implement and sustain these types of activities.

    Full Text Available Gut microbiota (GM plays several crucial roles in host physiology and influences several relevant functions. In more than one respect, it can be said that you “feed your microbiota and are fed by it.” GM diversity is affected by diet and influences metabolic and immune functions of the host’s physiology. Consequently, an imbalance of GM, or dysbiosis, may be the cause or at least may lead to the progression of various pathologies such as infectious diseases, gastrointestinal cancers, inflammatory bowel disease, and even obesity and diabetes. Therefore, GM is an appropriate target for nutritional interventions to improve health. For this reason, phytochemicals that can influence GM have recently been studied as adjuvants for the treatment of obesity and inflammatory diseases. Phytochemicals include prebiotics and probiotics, as well as several chemical compounds such as polyphenols and derivatives, carotenoids, and thiosulfates. The largest group of these comprises polyphenols, which can be subclassified into four main groups: flavonoids (including eight subgroups, phenolic acids (such as curcumin, stilbenoids (such as resveratrol, and lignans. Consequently, in this review, we will present, organize, and discuss the most recent evidence indicating a relationship between the effects of different phytochemicals on GM that affect obesity and/or inflammation, focusing on the effect of approximately 40 different phytochemical compounds that have been chemically identified and that constitute some natural reservoir, such as potential prophylactics, as candidates for the treatment of obesity and inflammatory diseases.

    Red blod cell (RBC)- and plasma-choline levels were measured in patients on lithium (n=96), antidepressants (n=32) and neuroleptics (n=51) and in 25 healthy drug-free controls. Lithium patients exhibited highly increased RBC- and slightly increased plasma-choline levels compared with controls (P<0.001 and P<0.05, respectively); the choline ratio (RBC-/plasma-choline) was elevated almost to the same extent as RBC-choline (P<0.001). With antidepressants RBC-choline and choline ratios were slightly reduced (P<0.05), whereas neuroleptics showed no effect on choline levels. 79% of lithium patients were responders (reduction in hospitalizations with lithium) 21% were non-responders (no reduction or increase in hospitalizations). Choline ratio exhibited a significant relation to prophylactic lithium response, but lithium ratio did not. The percentage of non-responders was significantly higher in patients with a choline ratio exceeding 100 than in patients with a choline ratio below this cut-off (P<0.01). Thus, the increase of RBC-choline and choline ratios appears to be an effect specific for lithium and might be related to the outcome of lithium prophylaxis. (author)

    Full Text Available Purpose. To determine if the use of combined HLA matched limbal stem cells allograft with amniotic membrane transplantation (AMT is a safe and effective prophylactic surgical procedure to prevent corneal graft after penetrating keratoplasty (PK. Methods. We report the case of a 17 years old patient with a history of congenital glaucoma, trabeculectomy and multiple corneal graft rejections, presenting total limbal cell deficiency. To reduce the possibility of graft rejection in the left eye after a new PK, a two step procedure was performed. At first the patient underwent a combined HLA matched limbal stem cells allograft (LAT and AMT and then, 10 months later, a new PK. Results. During 12 months of follow-up, the corneal graft remained stable and smooth, with no sign of graft rejection. Conclusions. In our patient, the prophylactic use of LAT from HLA-matched donors and AMT before PK, may result in a better prognosis of corneal graft survival.

    Fatigue is the most common toxicity of all grade toxicities with regorafenib, was the second most common toxicity in the CORRECT (regorafenib monotherapy for previously treated metastatic colorectal cancer) study, and is a major reason for early dose modification. The results from a recent randomized study suggested that dexamethasone (DEX) can improve cancer-related fatigue. We retrospectively analyzed the effect of prophylactic use of an oral DEX on fatigue during regorafenib treatment in patients with metastatic colorectal cancer (mCRC). A total of 105 patients who had received regorafenib at our institution from May 2013 to August 2014 were divided into 2 groups according to oral DEX use (2 mg/day; at the physician's discretion). Of the 105 patients, 31 received prophylactic DEX and 74 received regorafenib alone. The time to dose modification was significantly longer in the DEX group than in the no DEX group (15 days vs. 9 days; P = .009). The incidence of fatigue (grade ≥ 1) was significantly lower with DEX than without DEX (25.8% vs. 50.0%; P = .022). Fewer patients experienced a decreased appetite (grade ≥ 1; 3.2% vs. 35.1%; P regorafenib treatment, resulting in prolonging the time to dose modification for regorafenib. The decreased incidence of appetite loss and HFSR also suggest that concurrent DEX administration with regorafenib warrants further investigation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available New prophylactic and therapeutic strategies to combat human infections with highly pathogenic avian influenza (HPAI H5N1 viruses are needed. We generated neutralizing anti-H5N1 human monoclonal antibodies (mAbs and tested their efficacy for prophylaxis and therapy in a murine model of infection.Using Epstein-Barr virus we immortalized memory B cells from Vietnamese adults who had recovered from infections with HPAI H5N1 viruses. Supernatants from B cell lines were screened in a virus neutralization assay. B cell lines secreting neutralizing antibodies were cloned and the mAbs purified. The cross-reactivity of these antibodies for different strains of H5N1 was tested in vitro by neutralization assays, and their prophylactic and therapeutic efficacy in vivo was tested in mice. In vitro, mAbs FLA3.14 and FLD20.19 neutralized both Clade I and Clade II H5N1 viruses, whilst FLA5.10 and FLD21.140 neutralized Clade I viruses only. In vivo, FLA3.14 and FLA5.10 conferred protection from lethality in mice challenged with A/Vietnam/1203/04 (H5N1 in a dose-dependent manner. mAb prophylaxis provided a statistically significant reduction in pulmonary virus titer, reduced associated inflammation in the lungs, and restricted extrapulmonary dissemination of the virus. Therapeutic doses of FLA3.14, FLA5.10, FLD20.19, and FLD21.140 provided robust protection from lethality at least up to 72 h postinfection with A/Vietnam/1203/04 (H5N1. mAbs FLA3.14, FLD21.140 and FLD20.19, but not FLA5.10, were also therapeutically active in vivo against the Clade II virus A/Indonesia/5/2005 (H5N1.These studies provide proof of concept that fully human mAbs with neutralizing activity can be rapidly generated from the peripheral blood of convalescent patients and that these mAbs are effective for the prevention and treatment of H5N1 infection in a mouse model. A panel of neutralizing, cross-reactive mAbs might be useful for prophylaxis or adjunctive treatment of human cases of H5N1

    Full Text Available Background: Hepatic ischemia reperfusion is one the main causes for graft failure following transplantation. Although, the molecular events that lead to hepatic failure following ischemia reperfusion (IR are diverse and complex, previous studies have shown that excessive formation of reactive oxygen species (ROS are responsible for hepatic IR injury. Cerium oxide (CeO2 nanoparticles have been previously shown to act as an anti-oxidant and anti-inflammatory agent. Here, we evaluated the protective effects of CeO2 nanoparticles on hepatic ischemia reperfusion injury. Methods: Male Sprague Dawley rats were randomly assigned to one of the four groups: Control, CeO2 nanoparticle only, hepatic ischemia reperfusion (IR group and hepatic ischemia reperfusion (IR plus CeO2 nanoparticle group (IR+ CeO2. Partial warm hepatic ischemia was induced in left lateral and median lobes for 1h, followed by 6h of reperfusion. Animals were sacrificed after 6h of reperfusion and blood and tissue samples were collected and processed for various biochemical experiments. Results: Prophylactic treatment with CeO2 nanoparticles (0.5mg/kg i.v (IR+CeO2 group 1 hour prior to hepatic ischemia and subsequent reperfusion injury lead to a decrease in serum levels of alanine aminotransaminase and lactate dehydrogenase at 6 hours after reperfusion. These changes were accompanied by significant decrease in hepatocyte necrosis along with reduction in several serum inflammatory markers such as macrophage derived chemokine, macrophage inflammatory protein-2, KC/GRO, myoglobin and plasminogen activator inhibitor-1. However, immunoblotting demonstrated no significant changes in the levels of apoptosis related protein markers such as bax, bcl2 and caspase 3 in IR and IR+ CeO2 groups at 6 hours suggesting necrosis as the main pathway for hepatocyte death. Conclusion: Taken together, these data suggest that CeO2 nanoparticles attenuate IR induced cell death and can be used as a prophylactic

    Full Text Available Background : This study was designed to evaluate the use of laxative prophylaxis for constipation in intensive care unit (ICU and the impact of early versus late bowel movement on patient′s outcome. Methods : The study was a prospective, randomized controlled trial in critically ill ventilated adult patients, who were expected to stay on ventilator for >72 h. Control group did not receive any intervention for bowel movement for the first 72 h, whereas interventional group received prophylactic dose of lactulose 20 cc enterally every 12 h for the first 72 h. The parameters measured during the study were admission diagnosis, age, gender, comorbid conditions, admission Simplified Acute Physiologic Score (SAPS II, sedative and narcotic agents with doses and duration, timing and tolerance of nutrition, daily assessment of bowel movement, total use of prokinetic, doses of suppositories, and enema for first bowel movement, total number of days on ventilator, weaning failures, extubation or tracheostomy, ICU length of stay, and death or discharge. Results : A total of 100 patients were enrolled, 50 patients in each control and interventional group. Mean age was 38.8 years, and both groups had male predominance. Mean SAPS II score for both was 35. Mean dose of Fentanyl (323.8 ± 108.89 mcg/h in control and 345.83 ± 94.43 mcg/h in interventional group and mean dose of Midazolam (11.1 ± 4.04 mg/h in control and 12.4 ± 3.19 mg/h in interventional group. There were only two (4% patients in control, while nine (18% patients in interventional group who had bowel movement in <72 h (P < 0.05. Mean ventilator days were 16.19, and 17.36 days in control and interventional groups, respectively. Subgroup analysis showed that the patients who moved bowel in <5 days in both groups had mean ventilator days of 18.5, whereas it was 15.88 days for the patients who moved bowel after 5 days in both groups (P< 0.05. Mean ICU days for control was 21.15 ± 10.44 and 20

    1996-01-01

    Purpose: To determine the incidence of postimplant infection in patients who are not given prophylactic antibiotics (ATBs). Methods and Materials: One hundred thirty-one patients had computerized tomography (CT)-planned transperineal 125 I implantation of the prostate from 1988 through 1995. One hundred fourteen of the patients did not receive prophylactic ATBs, 19 of whom required postimplant Foley catheter drainage for 1 day or more for acute urinary retention. Results: The incidence of postimplant febrile episodes within 2 weeks of surgery among the patients who had not received prophylactic ATBs was 2 of 114 (2%). One of the two patients who developed postimplantation febrile episodes was treated successfully with ATBs as an outpatient. The second patient, who had a history of chronic lymphocytic leukemia (CLL) and immune suppression, developed E. coli sepsis and required intravenous antibiotics. Of 17 patients who received prophylactic ATBs, none had a postoperative febrile episode. Conclusion: We continue to refrain from routinely prescribing prophylactic ATBs unless there is some compelling circumstance including rheumatic heart disease, prosthetic devices, immune compromise, or a previous history of prostatitis

    Morphine is the reference treatment for severe acute pain in an emergency department. The purpose of this study was to describe and analyse opioid-related ADRs (adverse drug reactions) in a large cohort of emergency department patients, and to identify predictive factors for those ADRs. In this prospective, observational, pharmaco-epidemiological international cohort study, all patients aged 18years or older who were treated with morphine were enrolled. The study was done in 23 emergency departments in the US and France. Baseline numerical rating scale score and initial and total doses of morphine titration were recorded. Logistic regression analysis was used to study the effects of demographic, clinical and medical history covariates on the occurrence of opioid-induced ADRs within 6h after treatment. A total of 1128 patients were included over 10months. Median baseline initial pain scores were 8/10 (7-10) versus 3/10 (1-4) after morphine administration. Median titration duration was 10min (IQR, 1-30). The occurrence of opioid-induced ADRs was 25% and 2% were serious. Patients experienced mainly nausea and drowsiness. Medical history of travel sickness (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.01-2.86) and history of nausea or vomiting post morphine (OR, 3.86; 95% CI, 2.29-6.51) were independent predictors of morphine related ADRs. Serious morphine related ADRs are rare and unpredictable. Prophylactic antiemetic therapy could be proposed to patients with history of travel sickness and history of nausea or vomiting in a postoperative setting or after morphine administration.

    Purpose: To provide data for estimation of fetal radiation dose (D{sub F}) from prophylactic hypogastric artery balloon occlusion (HABO) procedures. Methods: The Monte-Carlo-N-particle (MCNP) transport code and mathematical phantoms representing a pregnant patient at the ninth month of gestation were employed. PA, RAO 20° and LAO 20° fluoroscopy projections of left and right internal iliac arteries were simulated. Projection-specific normalized fetal dose (NFD) data were produced for various beam qualities. The effects of projection angle, x-ray field location relative to the fetus, field size, maternal body size, and fetal size on NFD were investigated. Presented NFD values were compared to corresponding values derived using a physical anthropomorphic phantom simulating pregnancy at the third trimester and thermoluminescence dosimeters. Results: NFD did not considerably vary when projection angle was altered by ±5°, whereas it was found to markedly depend on tube voltage, filtration, x-ray field location and size, and maternal body size. Differences in NFD < 7.5% were observed for naturally expected variations in fetal size. A difference of less than 13.5% was observed between NFD values estimated by MCNP and direct measurements. Conclusions: Data and methods provided allow for reliable estimation of radiation burden to the fetus from HABO.

    Of 147 patients with carcinoma of the esophagus resected at Saitama Cancer Center Hospital for 10 years, 98 cases were studied to evaluate post-operative prophylactic irradiation. The total dose of irradiation was up to 4,000 ∼ 5,000 rads of Linac X-ray and the irradiated field was T-shaped covering the upper mediastinal and bilateral cervical regions. The prognosis of the post-operative irradiated group (56 cases) was significantly better than that of the control group (42 cases) (p < 0.01). This study resulted in a five-year survival rate of 34.2 percent for patients in the post-operative irradiated group, compared to 16.7 percent for those in the control group. Further detailed comparative studies revealed similar results. Cancer recurrence occurred at the irradiated fields in 8 cases (14.3 %), though in 15 cases (35.7 %) of the control group. This suggested the local suppressive effect of the post-operative irradiation to the cancer recurrence. (author)

    Objective: To determine the efficacy of prophylactic administration of intravenous Ondansetron for prevention of spinal anaesthesia induced hypotension in lower segment caesarean section. Study Design: Double blinded randomized controlled trial. Place and Duration of Study: It was conducted in Anesthesiology department, CMH Rawalakot; from 3 Mar to 4 Jun 2014. Material and Methods: One hundred patients were selected for this study, and randomly divided in two groups of 50 each, using random numbers table. Both groups were preloaded with Ringer's lactate at dose of 10ml/kg. Group A received 04 mg of IV ondansetron 5 min prior to spinal anaesthesia, whereas Group B received normal saline 05 minutes before administration of Spinal Anaesthesia. Results: Average age of Group A was 28.62 +- 4.64 years, whereas that of Group B was 27.88 +- 3.98 (p-value= 0.394). Average weight of Group A was 70.30 +- 6.25 kg, whereas that of Group B was 70.74 +- 6.17 kg (p-value= 0.724). Hypotension was noted in 21 patients in group A (42 percent), whereas it was observed in 34 Patients in Group B (68 percent) (p-value= 0.009). Bradycardia was noted in 9 patients in Group A (18 percent) and 19 patients in Group B (p=0.026). Conclusion: Intravenous administration of 04 mg of intravenous ondansetron, 05 minutes prior to subarachnoid block, is effective in decreasing frequency of hypotension. (author)

    The current study was conducted to investigate the protective effect of spermine, a natural polyamine against toxicity of lead and /or gamma irradiation in male rats. Eight groups of rats were used in this study (control, irradiated group (6 GY), lead (40 mg/kg bw), spermine (10 mg/kg bw), lead plus irradiation, irradiation plus spermine, lead plus spermine, irradiation plus lead co-treated with spermine) for consecutive 14 days. Blood samples were used for complete blood count (CBC) and glucose 6-phosphate-dehydrogenase (G6PD) levels. Moreover, malondialdhyde (MDA), glutathione (GSH), metallothionein (MT) levels and catalase (CAT) activity were investigated in liver, kidney and brain. G6PD activity significantly decreased post exposure to lead and /or gamma irradiation. Hepatic, renal and brain MDA, GSH, MT and CAT were significantly increased in lead intoxicated group, while GSH, MT and CAT activity were significantly decreased in gamma-irradiated group. Spermine administration alleviated changes in CBC, G6PD, MDA, MT and CAT to normal control levels, but with significant increase in G6PD activity and platelets count. In conclusion, spermine acts as an antioxidant and plays a prophylactic role against intoxication with lead and/or gamma irradiation exposure.

    Full Text Available Proteoglycan (PG extracted from salmon nasal cartilage has potential to be a prophylactic agent. Daily oral administration of the PG attenuates systemic inflammatory response in the experimental mouse models. In this study, we applied the culture-independent approach to investigate an alteration of intestinal microbiota composition in PG-administered mice. The results indicated that the population level of bacilli increased in the small and large intestine upon PG administration. On the other hand, the population level of clostridia decreased in the large intestine. The proportion of bacteria that are able to ferment saccharides and produce short-chain fatty acids increased in the small intestine and decreased in the large intestine. Importantly, population level of probiotic lactobacilli and bacteria exhibiting the immunomodulatory effect increased in the PG-administered mice. In addition, several disease-associated bacteria decreased upon PG administration. These results provided an understanding of the specific role of PG involved in host immune modulation and supported our hypothesis that daily oral administration of PG improves the overall balance in composition of the intestinal microbial community.

    Development of efficient and cost effective vaccines have been recognized as the primary concern to improve the overall healthcare in a country. In order to achieve this goal, more improved and powerful adjuvants need to be developed. Lacking in the self-adjuvanting immuno-modulatory constituents, vaccines exhibit lower immunogenicity. Combining potent adjuvants with vaccines is the most appropriate method to enhance the efficacy of the vaccines. Hence, this review is focussed on the most potent adjuvants for the formulation of vaccines. Areas covered: This review focuses on Oil-based emulsions, Mineral compounds, Liposomes, Bacterial products, ISCOMs and most recently used nanomaterials as adjuvants for enhancing the antigenicity of vaccines. Furthermore, this review explains the immunological response elicited by various particles. Moreover, case studies are incorporated providing an in depth analyses of various adjuvant-containing vaccines which are currently used. Expert commentary: Enhanced fundamental knowledge about the adjuvants and their immuno-stimulatory capabilities and delivery mechanisms will facilitate the rational designing of prophylactic vaccines with better efficacy.

    Infections represent a leading cause of mortality in patients with acute ischemic stroke, but it is unclear whether prophylactic antibiotic treatment improves the outcome. We aimed to evaluate the effects of this treatment on infection incidence and short-term mortality. This was a pragmatic, prospective multicenter real-world analysis of previously independent consecutive patients with acute ischemic stroke who were >18 years, and who had at admission National Institutes of Health Stroke Scale (NIHSS) >11. Patients with infection at admission or during the preceding month, with axillary temperature at admission >37 °C, with chronic inflammatory diseases or under treatment with corticosteroids were excluded from the study. Among 110 patients (44.5 % males, 80.2 ± 6.8 years), 31 (28.2 %) received prophylactic antibiotic treatment, mostly cefuroxime (n = 21). Prophylactic antibiotic treatment was administered to 51.4 % of patients who developed infection, and to 16.4 % of patients who did not (p antibiotic treatment (RR 5.84, 95 % CI 2.03-16.79, p antibiotic treatment did not differ between patients who died during hospitalization and those discharged, or between patients who died during hospitalization or during follow-up and those who were alive 3 months after discharge. Prophylactic administration of antibiotics in patients with severe acute ischemic stroke is associated with an increased risk of infection during hospitalization, and does not affect short-term mortality risk.

    To investigate the effectiveness and safety of prophylactic surgical ligation of patent ductus arteriosus (PDA) on mortality and morbidity of preterm infants weighing less than 1000 g at birth. The study conducted a systematic search of available database from 1996-2008. Retrieved articles were assessed for eligibility and data was abstracted independently by two reviewers. Decisions to include studies for review and the methodological quality of included studies were asssessed in duplicate based on predetermined criteria. No language restrictions were applied. Only one eligible study that enrolled 84 extremely low birth weight infants was identified. Prophylactic surgical ligation of PDA resulted in a statistically significant reduction of severe stage II or III necrotizing enterocolitis, [RR 0.25, 95% CI (0.08, 0.83), P value 0.02, number needed to treat 5]. The study, however, found no statistically significant difference in mortality, intraventricular hemorrhage, bronchopulmonary dysplasia, and retinopathy of prematurity. Current evidence does not support the use of prophylactic surgical ligation of PDA in the management of the preterm infants

    2005-01-01

    Purpose: To investigate whether prophylactic cranial irradiation (PCI) has a role in the management of patients with non-small-cell lung cancer (NSCLC) treated with curative intent. Methods and Materials: A search strategy was designed to identify randomized controlled trials (RCTs) comparing PCI with no PCI in NSCLC patients treated with curative intent. The electronic databases MEDLINE, EMBASE, LILACS, and Cancerlit were searched, along with relevant journals, books, and review articles to identify potentially eligible trials. Four RCTs were identified and reviewed. A total of 951 patients were randomized in these RCTs, of whom 833 were evaluable and reported. Forty-two patients with small-cell lung cancer were excluded, leaving 791 patients in total. Because of the small patient numbers and trial heterogeneity, no meta-analysis was attempted. Results: Prophylactic cranial irradiation did significantly reduce the incidence of brain metastases in three trials. No trial reported a survival advantage with PCI over observation. Toxicity data were poorly collected and no quality of life assessments were carried out in any trial. Conclusion: Prophylactic cranial irradiation may reduce the incidence of brain metastases, but there is no evidence of a survival benefit. It was not possible to evaluate whether any radiotherapy regimen is superior, and the effect of PCI on quality of life is not known. There is insufficient evidence to support the use of PCI in clinical practice. Where possible, patients should be offered entry into a clinical trial

    1992-08-29

    About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

    Breast cancer is the most common oncologic disease in the female population. Besides the sporadic occurrence, it occurs in the familial or hereditary form. Genetic testing for mutation BRCA1 and BRCA2 helps to identify women, who are at increased risk of developing breast and ovarian cancer. Women with the hereditary form of breast cancer occurs in 5 -10%. Women with mutations BRCA1 and BRCA2 have to be classified to intensive dispensaration, and may consider several options for breast cancer prevention, as prophylactic mastectomy, prophylactic salpingo-oophorectomy or chemo prevention.

    Clinically significant bleeding (CSPEB) is the most common adverse event following endoscopic mucosal resection (EMR) of large sessile and laterally spreading colorectal lesions (LSLs), and is associated with morbidity and resource utilization. CSPEB occurs more frequently with proximal LSLs. Prophylactic clipping of the post-EMR defect may be beneficial in CSPEB prevention. The aim of this study was to determine the cost-effectiveness of a prophylactic clipping strategy. We hypothesized that prophylactic clipping in the proximal colon was cost-effective. An economic model was applied to outcomes from the Australian Colonic Endoscopic Mucosal Resection (ACE) Study. Clip distances of 3, 5, 8, and 10 mm were analyzed. The cost of treating CSPEB was determined from an independent costing agency. The funds needed to spend (FNS) was the cost incurred in order to prevent one episode of CSPEB. A break-even analysis was performed to determine cost equivalence of the costs of clipping and CSPEB. Outcomes of 1717 LSLs (mean size 35.8 mm; 52.6 % proximal colon) that underwent EMR were analyzed. The overall rate of CSPEB was 6.4 % (proximal 8.9 %; distal 3.7 %). Endoscopic management was required in 45 % of CSPEB episodes. With a clip distance of 3 mm, the expected cost of prophylactic clipping was € 1106 per lesion compared with € 157 per lesion for the expected cost of CSPEB without clipping. At 100 % clipping efficacy, the FNS was € 14 826 (proximal and distal lesions € 9309 and € 29 540, respectively). A clip price of € 10.35 was required for the cost of clipping to offset the cost of CSPEB. A prophylactic clipping strategy is not cost-effective and at present cannot be justified for all lesions or selectively for lesions in the proximal colon.

    Cotrimoxazole prophylactic treatment (CPT) prevents opportunistic infections in HIV-infected or HIV-exposed children, but estimates of the effectiveness in preventing malaria vary. We reviewed studies that examined the effect of CPT on incidence of malaria in children in sub-Saharan Africa. We searched PubMed and EMBASE for randomised controlled trials (RCTs) and cohort studies on the effect of CPT on incidence of malaria and mortality in children and extracted data on the prevalence of sulphadoxine-pyrimethamine resistance-conferring point mutations. Incidence rate ratios (IRR) from individual studies were combined using random effects meta-analysis; confounder-adjusted estimates were used for cohort studies. The importance of resistance was examined in meta-regression analyses. Three RCTs and four cohort studies with 5039 children (1692 HIV-exposed; 2800 HIV-uninfected; 1486 HIV-infected) were included. Children on CPT were less likely to develop clinical malaria episodes than those without prophylaxis (combined IRR 0.37, 95% confidence interval: 0.21-0.66), but there was substantial between-study heterogeneity (I-squared = 94%, P < 0.001). The protective efficacy of CPT was highest in an RCT from Mali, where the prevalence of antifolate resistant plasmodia was low. In meta-regression analyses, there was some evidence that the efficacy of CPT declined with increasing levels of resistance. Mortality was reduced with CPT in an RCT from Zambia, but not in a cohort study from Côte d'Ivoire. Cotrimoxazole prophylactic treatment reduces incidence of malaria and mortality in children in sub-Saharan Africa, but study designs, settings and results were heterogeneous. CPT appears to be beneficial for HIV-infected and HIV-exposed as well as HIV-uninfected children. © 2014 John Wiley & Sons Ltd.

    Full Text Available Background and Objectives: Surgical site infection (SSI is the most common nosocomial infection encountered in post operative surgical wards. The use of prophylactic antibiotic in clean elective surgical cases is still a subject of controversy to surgeons. The objective of the study is to identify the need for using prophylactic antibiotics in clean surgeries, prevalence of organisms in patients who are not given prophylactic antibiotics and to study whether the presence of risk factors increase the incidence of surgical site infection. Methodology: The comparative study consists of 100 cases admitted under two groups of 50 each: Group A was given prophylactic antibiotic and Group B didn’t receive any. All surgeries other than clean surgical cases were excluded from the study. Results: Out of 50 patients in group B who were not given prophylactic antibiotic, 2 patients had more than one risk factor for development of SSI and both of them developed SSI. Of the 50 patients who received prophylactic antibiotic, none developed SSI. The rate of infection in group A was nil and in Group B was 4%. Conclusion: Prophylactic antibiotics are not recommended for clean elective surgical cases as there is no statistically significant change in the infection rate seen in patients not receiving prophylactic antibiotic(P=0.4952. Meticulous surgical technique and correcting risk factors prior to surgery is a must for reducing incidence of SSI.

    Full Text Available Objectives: To compare the effects of prophylactic ketamine and dexmedetomidine on postoperative bladder catheter-related discomfort/pain in patients undergoing cystoscopy. Methods: This prospective study was conducted on 75 American Society of Anesthesiologists (ASA I-II patients between 18-75 years of age and undergoing cystoscopy between November 2011 and June 2012 at Hacettepe University Hospital, Ankara, Turkey. Patients were randomly assigned to one of the 3 groups to receive 1 μ/kg dexmedetomidine, 250 μ/kg intravenous ketamine, or normal saline. All patients were questioned regarding probe-related discomfort, patient satisfaction, and pain at the end of the operation 0 (t0 and 15 (t1, 60 (t2, 120 (t3, and 360 (t4 minutes postoperatively. Evaluations were performed in person at the post-anesthesia care unit, or in ambulatory surgery rooms, or by phone calls. Results: Pain incidence in the dexmedetomidine and ketamine groups (p=0.042 was significantly lower than that in the control group (p=0.044.The sedation scores recorded at t0 in the dexmedetomidine and ketamine groups (p=0.004 were significantly higher than that of the control group (p=0.017. Patient groups were similar regarding the rate of hallucinations experienced at t1, no patients experienced hallucinations at t2, t3, or t4. Significantly more patients experienced hallucinations at t0 in the ketamine group than in the dexmedetomidine group (p=0.034 and the control group (p=0.005. Conclusion: Dexmedetomidine and ketamine had similar analgesic effects in preventing catheter-related pain; however, dexmedetomidine had a more acceptable side effect profile. To identify the optimal doses of dexmedetomidine and ketamine, more large-scale interventional studies are needed.

    INTRODUCTION: Prophylactic antibiotics (PRO) reduce the incidence of early-onset pneumonia in comatose patients with structural brain injury, but have not been examined in cardiac arrest survivors undergoing targeted temperature management (TTM). We investigated the effect of PRO on the development...... of pneumonia in that population. METHODS: We conducted a retrospective cohort study comparing patients treated with PRO to those not receiving PRO (no-PRO) using Northern Hypothermia Network registry data. Cardiac arrest survivors ≥ 18 years of age with a GCS...-34 °C were enrolled in the registry. Differences were analyzed in univariate analyses and with logistic regression models to evaluate independent associations of clinical factors with incidence of pneumonia and good functional outcome. RESULTS: 416 of 1240 patients (33.5%) received PRO. Groups were...

    Aim: To assess outcomes and usage rate of prophylactic radiologically inserted gastrostomy (RIG) in head and neck cancer (HNC) patients. Materials and methods: Outcome data of all HNC patients who underwent prophylactic RIG over a 22-month period (November 2007 to September 2009) in a tertiary referral centre were collected retrospectively. Thirty-day mortality, major and minor complication rates, and subsequent usage of the RIG were analysed. Results: Fifty-one HNC patients underwent prophylactic RIG. Three minor and no major immediate complications were identified. Sixteen minor and three major complications at 30-days were identified. Three (5.9%) major complications were identified. There was one death due to disease progression and not RIG insertion. The RIG was not used in 17.7% of patients post-procedure. Conclusion: Prophylactic RIG in HNC patients has a comparable mortality rate to RIG insertion in HNC patients with mixed indications. However, the number of cases where the gastrostomy is not used raises important concerns and warrants further investigation.

  6. The current status of prophylactic replacement therapy in children and adults with haemophilia.

    2015-06-01

    Initiating prophylactic treatment at an early age is considered to be the optimal form of therapy for a child with haemophilia A or B. The pioneering long term experiences of prophylactic treatment from Sweden and The Netherlands demonstrated the benefit of prophylaxis in retrospective and observational studies. Decades later, these benefits were confirmed in a randomized controlled study in USA. We review the current status of prophylactic replacement therapy of haemophilia in children, adolescents, adults and the elderly. Prophylaxis should begin at an early age and there are arguments for continuing it into adulthood. The dose of prophylaxis is dependent on the goal of treatment, economic resources and venous access and should be tailored individually. Starting the first exposures to clotting factor concentrates as prophylactic treatment, instead of on-demand in response to a bleed, may decrease the frequency of inhibitors in patients with haemophilia A. Novel longer-acting products are being introduced that could be helpful for patients with difficult venous access and enable higher trough levels. © 2015 John Wiley & Sons Ltd.

    We conducted this study to clarify the current clinical practice of prophylactic colectomy for patients with familial adenomatous polyposis (FAP) in Japan. This retrospective multi-center cohort study involved 23 specialized institutions for colorectal disease in Japan. We analyzed the records of 147 patients who underwent prophylactic surgical treatment between 2000 and 2012. Patients were divided into Group 1 (2000-2006) and Group 2 (2007-2012) based on their date of surgery. Age at the time of prophylactic surgery was 27 and 31 years in Groups 1 and 2, respectively. The proportion of attenuated FAP was significantly lower in Group 2 than in Group 1 (1.0 vs. 13 %, respectively). Pathological examination revealed an increased incidence of malignant polyps in the resected specimens from Group 2 patients (10 vs. 23 %, respectively; P = 0.034). Laparoscopic surgery was more frequent in Group 2 than in Group 1 (61 vs. 40 %, respectively). There was no surgical mortality in either group. Prophylactic surgery for FAP results in good short-term surgical outcomes in Japan. The current surgical approach is characterized by limited surgical indications for patients with attenuated FAP, delayed timing of colectomy, and the increasing standardization of laparoscopic surgery.

    Objective was to evaluate the therapeutic and prophylactic effectiveness of oral zinc sulfate in recurrent aphthous stomatitis RAS in comparison with dapsone. A double-blind placebo controlled study, conducted in the Department of Dermatology, Baghdad Teaching Hospitals, Baghdad, Iraq between May 2005 and October 2006, in which 45 patents with RAS were recruited and divided into 3 equal groups: group A on zinc sulfate 150 mg twice daily, group B on dapsone 50 mg twice daily and group C on glucose 250 mg as placebo. The drugs were prepared in identical capsules and patents were instructed to take the capsules twice daily after meals in a double blind manner. Assessment of each patient was carried out by the Oral Clinical Manifestation Index OCMI and the diameter of the ulcers at day 0, day 4 and the second, fourth, sixth, eighth, tenth and twelfth weeks of the therapy. Forty-five patients were included in the study 25 males and 20 females and their ages ranged between 16-45 years mean +/-SD 31.24+/-8.14. In group A, the mean of OCMI and diameters of the ulcers improved, with a p=0.0001 for OCMI, and 0.0001 for the diameter for ulcers at the end of the twelfth week of therapy, which was statistically significant. Group B also showed significant improvement, however, the action was lower and slower p=0.0001 for OCMI and 0.001 for the diameter for ulcers. Group C revealed slight non-significant improvement p=0.028 for OCMI and 0.034 for the diameter of ulcers. In the sixth week of therapy, zinc sulfate was more effective than dapsone in reducing in reducing the reducing the OCMI of the ulcers p=0.007. The present study showed that both zinc sulfate and dapsone had significant therapeutic and prophylactic affects in controlling RAS, however, zinc sulfate had much more rapid and sustained action.

    The indications for prophylactic antibiotics in plastic surgery remain controversial. No recent survey has been reported on the use of prophylactic antibiotics by plastic surgeons in clinical practice. This survey was designed to assess the current use of prophylactic antibiotics by plastic surgeons and to compare trends with previous studies. All members of the American Society of Plastic Surgeons with an e-mail address on the Society's website were contacted via an e-mail and sent a link to a SurveyMonkey questionnaire. To survey only in those subspecialty areas that they practice in, surgeons were queried only on the procedures that they perform. Within each section, a list of common representative procedures was included, with questions about the use of antibiotic prophylaxis. A total of 3824 American Society of Plastic Surgeons members were contacted. Of the 3613, 910 with working e-mail addresses responded to the survey for a response rate of 25%. And 833 or 91.5% completed the survey. Survey data cover the percentage of surgeons reporting their use of antibiotics in procedures that they currently perform. The percentage of plastic surgeons who use prophylactic antibiotics in almost all procedures studied has increased significantly when compared with earlier studies. The use of prophylactic antibiotics by plastic surgeons has increased considerably since the prior studies by Krizek et al (Plast Reconstr Surg. 1975;55:21-32 and 1985;76:953-963). Some of these uses are appropriate because of the use in procedures involving implants and longer operations. The elevated rates for clean procedures are not part of the evidence-based practice.

    The objective of this article is to prospectively investigate the efficacy of amnioinfusion as a means to reduce febrile morbidity in pregnancies complicated by chorioamnionitis. All laboring patients with a temperature > or =100.1 degrees F were approached for study participation. Exclusion criteria included amnionitis diagnosed at greater than 8 cm dilation, multiple gestation, placental abruption, or a nonreassuring fetal heart rate tracing. Consenting patients were randomized to receive antibiotics (ampicillin or penicillin with gentamicin) and acetaminophen with or without amnioinfusion. All patients received intrauterine pressure catheter placement. For study patients, normal saline at room temperature was infused at 10 mL/min for 60 min, then 3 mL/min until delivery. Postpartum endometritis was defined as a temperature = 100.4 degrees F accompanied by uterine tenderness more than 12 hr after delivery. Statistical analysis was performed using the Student's t-test for continuous data and Chi-square for discrete variables. Thirty-six patients were enrolled, and complete data were available for 34 patients (17 in each group). There were no differences between groups with respect to maternal age, gravidity, race, or gestational age. There were also no differences between groups in duration of rupture of membranes, temperature at randomization, interval from randomization to delivery, cesarean section rate, or umbilical cord arterial pH. The mean temperature at the time of delivery was 99.8+/-0.9 degrees F for the amnioinfusion group versus 100.5+/-1.0 degrees F for the control group (p=0.046). Three of 17 amnioinfusion patients and 3 of 17 control patients had postpartum endometritis. There was 1 neonatal infection in the treatment group and no neonatal infections among the control patients. Prophylactic amnioinfusion was associated with a decline in temperature at the time of delivery. No untoward effects from the amnioinfusion were identified.

    Background Contralateral prophylactic mastectomy (CPM) rates have been increasing in the U.S. Though some studies have reported high overall satisfaction among women who undergo CPM, it is unclear how long-term satisfaction differs from that of women who undergo unilateral mastectomy (UM). Furthermore, few studies have assessed whether the effects of CPM on body image differ from those of breast conserving surgery (BCS) or UM. Methods We analyzed responses from a survey of women with both a personal and family history of breast cancer who were enrolled in the Sister Study (n=1176). Among women who underwent mastectomy, satisfaction with mastectomy decision and reconstruction was compared between women who underwent CPM and UM. We also evaluated responses on 5 items related to body image according to surgery type (BCS, UM without reconstruction, CPM without reconstruction, UM with reconstruction, and CPM with reconstruction). Results Participants were, on average, 60.8 years old at diagnosis (SD=8.7) and 3.6 years post-diagnosis at the time of survey (SD=1.7). BCS was the most common surgical treatment reported (63%), followed by CPM (22%) and UM (15%). Satisfaction with mastectomy decision was reported by 97% of women who underwent CPM and 89% of those who underwent UM. Compared to other surgery types, women who underwent CPM without reconstruction reported feeling more self-conscious, less feminine, less whole, and less satisfied with the appearance of their breasts. Body image was consistently highest among women who underwent BCS. Conclusions In our sample of women with both a personal and family history of breast cancer, most were highly satisfied with their mastectomy decision, including those who elected to undergo CPM. However, body image was lowest among women who underwent CPM without reconstruction. Our findings may inform decisions among women considering various courses of surgical treatment. PMID:28058563

    To evaluate associations between prophylactic preoperative antibiotic choice and surgical site infection rates after hysterectomy. A retrospective cohort study was performed of patients in the Michigan Surgical Quality Collaborative undergoing hysterectomy from July 2012 to February 2015. The primary outcome was a composite outcome of any surgical site infection (superficial surgical site infections or combined deep organ space surgical site infections). Preoperative antibiotics were categorized based on the recommendations set forth by the American College of Obstetricians and Gynecologists and the Surgical Care Improvement Project. Patients receiving a recommended antibiotic regimen were categorized into those receiving β-lactam antibiotics and those receiving alternatives to β-lactam antibiotics. Patients receiving nonrecommended antibiotics were categorized into those receiving overtreatment (excluded from further analysis) and those receiving nonstandard antibiotics. Multivariable logistic regression models were developed to estimate the independent effect of antibiotic choice. Propensity score matching analysis was performed to validate the results. The study included 21,358 hysterectomies. The overall rate of any surgical site infection was 2.06% (n=441). Unadjusted rates of "any surgical site infection" were 1.8%, 3.1%, and 3.7% for β-lactam, β-lactam alternatives, and nonstandard groups, respectively. After adjusting for patient and operative factors within clusters of hospitals, compared with the β-lactam antibiotics (reference group), the risk of "any surgical site infection" was higher for the group receiving β-lactam alternatives (odds ratio [OR] 1.7, confidence interval [CI] 1.27-2.07) or the nonstandard antibiotics (OR 2.0, CI 1.31-3.1). Compared with women receiving β-lactam antibiotic regimens, there is a higher risk of surgical site infection after hysterectomy among those receiving a recommended β-lactam alternative or nonstandard regimen.

    Routine sentinel lymph node (SLN) surgery during prophylactic mastectomy (PM) is unnecessary, because most PMs do not contain cancer. Our institution utilizes intraoperative pathology to guide the surgical decision for resection of SLNs in PM. The purpose of this study was to review the effectiveness of this approach. We identified all women aged ≥18 years who underwent bilateral PM (BPM) or contralateral PM (CPM) at our institution from January 2008 to July 2016. We evaluated the frequency of SLN resection and rate of occult breast cancer (DCIS or invasive disease) in the PM. We used the following definitions: over-treatment-SLN surgery in patients without cancer; under-treatment-no SLN surgery in patients with cancer; appropriate treatment-no SLN in patients without cancer or SLN surgery in patients with cancer. PM was performed on 1900 breasts: 1410 (74.2%) CPMs and 490 (25.8%) BPMs. Cancer was identified in 58 (3.0%) cases (32 invasive disease and 26 DCIS) and concurrent SLN surgery was performed in 44 (75.9%) of those cases. Overall, SLN surgery guided by intraoperative pathology resulted in appropriate treatment of 1787 (94.1%) cases: 1319 (93.5%) CPMs and 468 (95.5%) BPMs, by avoiding SLN in 1743/1842 cases without cancer (94.6%), and performing SLN surgery in 44/58 cases with cancer (75.9%). Use of intraoperative pathology to direct SLN surgery in patients undergoing PM minimizes over-treatment from routine SLN in PM and minimizes under-treatment from avoiding SLN in PM, demonstrating the value of intraoperative pathology in this era of focus on appropriateness of care.

  5. Early T Cell Recognition of B Cells following Epstein-Barr Virus Infection: Identifying Potential Targets for Prophylactic Vaccination.

    Full Text Available Epstein-Barr virus, a B-lymphotropic herpesvirus, is the cause of infectious mononucleosis, has strong aetiologic links with several malignancies and has been implicated in certain autoimmune diseases. Efforts to develop a prophylactic vaccine to prevent or reduce EBV-associated disease have, to date, focused on the induction of neutralising antibody responses. However, such vaccines might be further improved by inducing T cell responses capable of recognising and killing recently-infected B cells. In that context, EBNA2, EBNA-LP and BHRF1 are the first viral antigens expressed during the initial stage of B cell growth transformation, yet have been poorly characterised as CD8+ T cell targets. Here we describe CD8+ T cell responses against each of these three "first wave" proteins, identifying target epitopes and HLA restricting alleles. While EBNA-LP and BHRF1 each contained one strong CD8 epitope, epitopes within EBNA2 induced immunodominant responses through several less common HLA class I alleles (e.g. B*3801 and B*5501, as well as subdominant responses through common class I alleles (e.g. B7 and C*0304. Importantly, such EBNA2-specific CD8+ T cells recognised B cells within the first day post-infection, prior to CD8+ T cells against well-characterised latent target antigens such as EBNA3B or LMP2, and effectively inhibited outgrowth of EBV-transformed B cell lines. We infer that "first wave" antigens of the growth-transforming infection, especially EBNA2, constitute potential CD8+ T cell immunogens for inclusion in prophylactic EBV vaccine design.

    Full Text Available  INTRODUCTION. High risk of venous thrombosis in patients with multisystem trauma is associated with a number of precipitating factors, such as direct damage to vessels, prolonged immobilization, major changes in the hemostatic system, as well as possible surgical intervention.THE PURPOSE OF THE STUDY. Analysis of the incidence, echosemiotics, and evolutionof venous thrombosis in the course of various prophylactic drug therapies in patients with polytrauma.METHODS. The results of leg veins ultrasonography in 610 patients with various prophylactic drugtherapies have been analyzed over time. Antiplatelet agentswere received by 314 patients of the first group, low molecular weight heparins — 186 patients of the second group, oral anticoagulants — 110 patients of the third group. THE RESulTS Evolved thromboses varied in frequency (52.5% in the first group, 15.6% in the 2nd group and 10% in the 3rd group, prevalence, nature of the proximal border, with an increase in the proportion of nonocclusive lesions in the 2nd and 3rd groups, as well as in start time and degree of recanalization.CONCLUSION. Low molecular weight heparins and oral anticoagulants reduce the risk of venous thrombosis by 3.3 and 5 times respectively, compared to the group of patients who did not receive anticoagulants in the early posttraumatic period; recanalization begins 1−2 weeks earlier with more effective restoration of the lumen. As the number of thromboses in the course of modern anticoagulants decreases, the proportion of non-occlusive thromboses including the floating onesgrows, requiring ultrasoundobservation.

    To assess HPV prophylactic vaccine coverage among French high school and university students as well as their level of education about this vaccine. An anonymous survey was conducted among 2500 high school and university students from the area of Marseilles, France, from December 2009 to April 2010. A total of 2018 questionnaires were collected (80.7% participation rate). Mean age of participants was 20 years (range, 15-45 years). Only 671 (35.4%) participants reported having been vaccinated against HPV, of whom 510 (73.4%) had completed the three injections scheme. Practice of cytological cervical cancer screening was not significantly influenced by vaccination status. Thus, 578 (45.2%) participants who had not been vaccinated already had had a cervical cytology performed, versus 295 (43.3%) vaccinated ones (P=0.445). Among those not being vaccinated, 671 (49.8%) fulfilled criteria for a catch-up vaccination, of whom only 325 (48.4%) agreed for such a catch-up. Main reasons given for refusal for a catch-up vaccination were the lack of information about HPV vaccine and fear of side effects. In total, 1722 (90%) considered themselves as educated about the HPV vaccine. Source of education was attributed to doctors and media by 54.4% and 53.7% of participants, respectively. Educational role attributed to school and university was poor (3.4%). Despite apparent satisfactory level of education, HPV prophylactic vaccine coverage among high school and university students appears to be insufficient. Copyright © 2011 Elsevier Masson SAS.

    Purpose: To ascertain whether the time from injury to prophylactic radiation therapy (RT) influences the rate of heterotopic ossification (HO) after operative treatment of displaced acetabular fractures. Methods and Materials: This is a single-institution, retrospective analysis of patients referred for RT for the prevention of HO. Between January 2000 and January 2009, 585 patients with displaced acetabular fractures were treated surgically followed by RT for HO prevention. We analyzed the effect of time from injury on prevention of HO by RT. In all patients, 700 cGy was prescribed in a single fraction and delivered within 72 hours postsurgery. The patients were stratified into five groups according to time interval (in days) from the date of their accident to the date of RT: Groups A {<=}3, B {<=}7, C {<=}14, D {<=}21, and E >21days. Results: Of the 585 patients with displaced acetabular fractures treated with RT, (18%) 106 patients developed HO within the irradiated field. The risk of HO after RT increased from 10% for RT delivered {<=}3 days to 92% for treatment delivered >21 days after the initial injury. Wilcoxon test showed a significant correlation between the risk of HO and the length of time from injury to RT (p < 0.0001). Chi-square test and multiple logistic regression analysis showed no significant association between all other factors and the risk of HO (race, gender, cause and type of fracture, surgical approach, or the use of indomethacin). Conclusions: Our data suggest that there is higher incidence and risk of HO if prophylactic RT is significantly delayed after a displaced acetabular fracture. Thus, RT should be administered as early as clinically possible after the trauma. Patients undergoing RT >3 weeks from their displaced acetabular fracture should be informed of the higher risk (>90%) of developing HO despite prophylaxis.

    Heated humidifiers (HH) enable effective treatment of upper airway dryness during nasal continuous positive airway pressure (nCPAP) therapy for obstructive sleep apnoea (OSA), but the role of prophylactic use of HH during the initiation of nCPAP treatment has not been studied so far. The aim of the present study was to investigate whether prophylactic HH during the initiation of CPAP would result in improved initial patient comfort and acceptance. In 44 consecutive, previously untreated OSA patients with no history of upper airway dryness, CPAP titration with and without HH was performed on two consecutive nights in a randomised order. The patients were interviewed after each treatment night in order to establish the comfort of the treatment, and, after the second treatment, they were asked which of the two nights they considered more pleasant, and which treatment they would prefer for long-term use. Following CPAP titration with HH, 32 patients (73%) claimed to have had a better night's sleep than usual (i.e. without CPAP treatment) compared with 33 patients (75%) saying the same following CPAP treatment without HH. For 21 patients (47.7%) treatment with HH was more pleasant, 23 (52.3%) saw no difference or said that treatment without HH was more pleasant. Nineteen patients (43.2%) gave preference to treatment with HH for long-term use, while 25 patients (56.8%) had no preference or said they would prefer treatment without HH. The use of HH during the initiation phase of CPAP treatment was associated neither with an initial improvement in comfort nor with greater initial treatment acceptance. Copyright 2002 S.

    To determine the difference in infection rate between 24h versus five days of prophylactic antibiotic use in management of Gustilo II open tibia fractures. Unblinded randomized control trial. Accident and Emergency, orthopedic wards and outpatient clinics at Kenyatta National Hospital (KNH). The study involved patients aged 18-80 years admitted through accident and emergency department with Gustilo II traumatic open tibia fractures. Patients were randomized into either 24hour or five day group and antibiotics started for 24hours or five days after surgical debridement. The wounds were exposed and scored using ASEPSIS wound scoring system for infection after 48h, 5days and at 14days. The main outcomes of interest were presence of infection at days 2, 5 and 14 and effect of duration to antibiotic administration on infection rate. There was no significant difference in infection rates between 24-hour and 5-day groups with infection rates of 23% (9/40) vs. 19% (7/37) respectively (p=0.699). The infection rate was significantly associated with time lapsed before administration of antibiotics (p=0.004). In the use of prophylactic antibiotics for the management of Gustilo II traumatic open tibia fractures, there is no difference in infection rate between 24hours and five days regimen but time to antibiotic administration correlates with infection rate. Antibiotic use for 24hours only has proven adequate prophylaxis against infection. This is underlined in our study which we hope shall inform practice in our setting. A larger, more appropriately controlled study would be useful. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The purpose of this study was to investigate whether prophylactic administration of melatonin to the mother throughout pregnancy could protect against ischemia/reperfusion (I/R)-induced oxidative brain damage in neonatal rats. The utero-ovarian arteries were occluded bilaterally for 30 min in female Wistar rats on day 16 of pregnancy to induce fetal ischemia. Reperfusion was achieved by releasing the occlusion and restoring circulation. A sham operation was performed in control rats. Melatonin solution or vehicle alone was administrated orally throughout pregnancy. We collected brain mitochondria from neonatal rats, evaluated mitochondrial structure by electron microscopy, and measured the respiratory control index (RCI) as an indicator of mitochondrial respiratory activity as well as the concentration of thiobarbituric acid-reactive substances (TBARS), a marker of oxidative stress. Histological analysis was performed at the Cornu Ammonis 1 (CA1) and Cornu Ammonis 3 (CA3) regions of the hippocampus. I/R significantly reduced the RCI and significantly elevated the concentration of TBARS. Melatonin treatment reversed these effects, resulting in values similar to that in untreated, sham-ischemic animals. Electron microscopic evaluation showed that the number of intact mitochondria decreased in the I/R group, while melatonin treatment preserved them. Histological analysis revealed a decrease in the ratio of normal to whole pyramidal cell number in the CA1 and CA3 regions in the I/R group. While melatonin administration protected against degeneration. These results indicate that prophylactic administration of melatonin to the mother throughout pregnancy may prevent I/R-induced oxidative brain damage in neonatal rats.

    Placenta accrete patients whose mother mortality rates are rather high due to massive bleeding during childbirth need to have Prophylactic placement of Internal Iliac Artery Balloon Occlusion Catheters procedure to reduce amount of blood loss and inoperative transfusion. Nevertheless, studies for mothers inevitably exposed to dose during PIIABOCs procedure have not been published many yet. Therefore, this study is to investigate exact information on radiation dose exposed to fetus during PIIABOCs procedure. Average effective dose of fetus per organ is 2.38∼8.83 mGy, measured highest at beam center and followed by eyeball, stomach and bladder. The result showed that the longer fluoroscopy time is used, the closer beam center is and the thicker abdominal thickness is, the more effective dose on fetus is increasing. When using the collimator and protection shown to decrease the effective dose and when using higher the patient table shown to decrease the effective dose. It has been reported that the threshold of deterministic effect is about 100mGy. Deterministic effect was regarded as a factor that would influence on fetus exposed by medical radiation than stochastic effect. Consequently, it concluded that dose exposed on fetus in PIIABOCs procedure was approximately 10% of threshold of deterministic effect with effective dose of 0.49∼18.27 mGy.

    Purpose: To evaluate the effectiveness of prophylactic tamsulosin (Flomax) in reducing the urinary symptoms in patients undergoing 125 I prostate implantation (PI) for prostate adenocarcinoma. Methods and materials: This is a single-institution, double-blind, placebo-controlled, randomized trial for patients undergoing PI for prostate adenocarcinoma comparing prophylactic tamsulosin versus placebo. Eligibility criteria included patients not taking tamsulosin or other α-blockers treated with PI. The patients were randomly assigned to either tamsulosin (0.8 mg, orally once a day) or matched placebo. All patients started the medication 4 days before PI and continued for 60 days. The American Urologic Association (AUA) symptom index questionnaire was used to assess urinary symptoms. The AUA questionnaire was administered before PI for a baseline score and weekly for 8 weeks after PI. Patients were taken off the study if they developed urinary retention, had intolerable urinary symptoms, or wished to discontinue with the trial. Results: One hundred twenty-six patients were enrolled in this study from November 2001 to January 2003 (118 were evaluable: 58 in the tamsulosin arm and 60 in the placebo group). Pretreatment and treatment characteristics were comparably matched between the two groups. The urinary retention rate was 17% (10 patients) in the placebo group compared with 10% (6 patients) in the tamsulosin group (p = 0.3161). Eighty-eight percent (14 patients) of those who developed urinary retention experienced it within 2 weeks after the PI. Intolerable urinary symptoms were reported equally (10 patients in each group) with 70% occurring in the first 2 weeks after PI. There was a significant difference in mean AUA score in favor of tamsulosin at Week 5 after PI (p = 0.03). Conclusions: Prophylactic tamsulosin (0.8 mg/day) before prostate brachytherapy did not significantly affect urinary retention rates, but had a positive effect on urinary morbidity at Week 5

    Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication of ERCP and may run a severe course. Evidence suggests that vigorous periprocedural hydration can prevent PEP, but studies to date have significant methodological drawbacks. Importantly, evidence for its added value in patients already receiving prophylactic rectal non-steroidal anti-inflammatory drugs (NSAIDs) is lacking and the cost-effectiveness of the approach has not been investigated. We hypothesize that combination therapy of rectal NSAIDs and periprocedural hydration would significantly lower the incidence of post-ERCP pancreatitis compared to rectal NSAIDs alone in moderate- to high-risk patients undergoing ERCP. The FLUYT trial is a multicenter, parallel group, open label, superiority randomized controlled trial. A total of 826 moderate- to high-risk patients undergoing ERCP that receive prophylactic rectal NSAIDs will be randomized to a control group (no fluids or normal saline with a maximum of 1.5 mL/kg/h and 3 L/24 h) or intervention group (lactated Ringer's solution with 20 mL/kg over 60 min at start of ERCP, followed by 3 mL/kg/h for 8 h thereafter). The primary endpoint is the incidence of post-ERCP pancreatitis. Secondary endpoints include PEP severity, hydration-related complications, and cost-effectiveness. The FLUYT trial design, including hydration schedule, fluid type, and sample size, maximize its power of identifying a potential difference in post-ERCP pancreatitis incidence in patients receiving prophylactic rectal NSAIDs.

    The success of prophylactic digitalization in reducing the incidence of supraventricular tachyarrhythmias (SVT) was studied in 140 randomly grouped, consecutive patients undergoing myocardial revascularization operations. The test group received either 1 or 1.5 mg. of digoxin the day before operation and were maintained postoperatively on 0.25 mg. of digoxin daily. There was a significant increase (p less than 0.05) in the incidence of SVT in the treated patients (17 of 61 or 27.8 percent) vs. the untreated patients (nine of 79 or 11.4 percent). There was no significant difference in SVT with the two digitalization dosage levels (31.6 percent with 1 mg. vs. 21.7 percent with 1.5 mg.). Prophylactic digitalization demonstrates no benefit in the prevention of SVT following myocardial revascularization and may, in fact, predispose the patient to these arrhythmias.

  16. Retroperitoneal Bleeding: An Experience During Prophylactic Anticoagulation in a Patient With Nephrotic Syndrome

    Full Text Available The association between nephrotic syndrome (NS and a hypercoagulable state has been demonstrated. Controlling the blood clotting activity may therefore be attractive for patients with nephrosis in terms of thromboembolism prophylaxis. We herein report a 75-year-old woman with minimal change disease who developed pains in the right back, groin, and thigh because of retroperitoneal bleeding during prophylactic anticoagulation with unfractionated heparin. Although this procedure has not been accepted as the standard of care for patients with nephrosis, pharmacologic prophylaxis may already be practiced empirically, as in the present patient. We believe that our experience highlights the pitfalls of such a management in patients with nephrosis, implying the need for a diagnostic strategy for identifying those patients with NS who can benefit from prophylactic anticoagulation. Several concerns that emerged in this case are also discussed.

  18. Effects of zacopride and BMY25801 (batanopride) on radiation-induced emesis and locomotor behavior in the ferret

    1990-01-01

    The antiemetic and locomotor effects of two substituted benzamides, zacopride and batanopride (BMY25801), were compared in ferrets after bilateral 60Co irradiation at 2, 4 or 6 Gy. Both zacopride and BMY25801 were effective against emesis and related signs. Zacopride, tested at several doses (0.003, 0.03 and 0.3 mg/kg), appeared to be more potent because it abolished emesis at 100-fold lower doses than did BMY25801 (3 mg/kg). The ED50 value for the antiemetic effect of zacopride was 0.026 mg/kg (confidence levels = 0.0095, 0.072 mg/kg). However, analysis of emetic parameters recorded from vomiting animals (e.g., latency to first emesis) demonstrated that BMY25801 provided greater antiemetic protection in this population than zacopride without any apparent side effects. Locomotor activity was significantly depressed by both radiation (all doses) and zacopride alone (0.03 mg/kg and 0.3 mg/kg). BMY25801 alone did not affect locomotor activity, and protected against the radiation-induced locomotor decrement. Although zacopride potentiated the locomotor decrement to radiation, no clear dose-response relationship was evident. Bilateral abdominal vagotomy significantly increased the latency to the first emetic episode and significantly reduced the number of retches, but did not alter the duration of the prodromal response to 4-Gy irradiation. Unilateral vagotomies had no effect. Zacopride (at 0.03 mg/kg and 0.3 mg/kg) remained an effective antiemetic in animals that received a bilateral vagotomy, abolishing emesis in four of eight and two of eight ferrets, respectively. These data suggest that the antiemetic action of zacopride does not fully depend on intact vagal innervation and also acts via other pathways

    Full Text Available In competitive and constantly changing market conditions special attention has been paid to market researches. The results of these studies become the basis for formation of sales estimates, and projected levels of revenues and profits from sales. Market researches are the essential condition to make offered goods successful at the market. It is market researches that help companies to realize the control of consumers' needs changing. The market researches on demand for dietary and prophylactic nutrition in the Saratov Region have been the research objective. In accordance with the given objective the following goals have been formed: 1 finding out the most spread diseases among the population; 2 determination of the average age of people suffering from one or another disease; 3 studying demand of products with food fiber additives; 4 analysis of respondent's preference regarding the addition of natural vegetable additives to foodstuff; 5 demand for dietary and prophylactic foodstuff among the population. Since the survey has been carried out among people suffering from various diseases, particular attention during the market research has been turned to the medical and prophylactic properties of food fibers to find out the attitude of the respondents to functional foodstuff. The dynamics of noninfectious diseases, the population health status depending on age, and increase of overweight people during 2012–2014 have been shown. As a result of questionnaire data processing it has been ascertained that the population is of low awareness regarding the necessity to consume foodstuff with radioprotective and chelator properties. The researches have demonstrated that dietary and prophylactic foodstuff is in demand and consequently the development of such products is reasonable.

  20. Evidence-based analysis of prophylactic treatment of asymptomatic retinal breaks and lattice degeneration.

    Wilkinson, C P

    2000-01-01

    To assess the quality of information in the literature regarding the benefits of prophylactic treatment of asymptomatic retinal tears and lattice degeneration. Asymptomatic retinal breaks occur in approximately 7% of patients over age 40, and lattice degeneration is present in approximately 8% of the general population. Because retinal breaks cause retinal detachment and lattice degeneration is associated with approximately 30% of retinal detachments, prophylactic treatment of these lesions has sometimes been recommended. A panel of vitreoretinal experts performed a literature review of all publications regarding prevention of retinal detachment that have been published in English. These articles were then used to prepare recommendations for patient care in an American Academy of Ophthalmology Preferred Practice Pattern (PPP). Each recommendation was rated according to: (1) its importance in the care process and (2) the strength of evidence supporting the given recommendation. Most recommendations were rated as A (most important to patient care). Only a single publication was graded as I (providing strong evidence in support of a recommendation), and this was not a prospective trial. Of the few publications rated as II (substantial evidence), most were studies documenting a lack of treatment benefit. Because of an absence of level I and level II studies in the literature, level III (consensus of expert opinion) was the basis for most recommendations in the PPP. The current literature regarding prevention of retinal detachment does not provide sufficient information to support strongly prophylactic treatment of lesions other than symptomatic flap tears. Prospective randomized trials of prophylactic therapy are indicated. Eyes highly predisposed to retinal detachment should be considered for such studies.

    Controversy exists over the prophylactic treatment of predisposing lesions to prevent retinal detachment. Seven hundred sixty consecutive phakic fellow eyes with rhegmatogenous retinal detachment in the first eye were examined by the same vitreoretinal surgeon before detachment surgery and for a follow-up period ranging from 1 to 72 months, with a mean of 36 months. During this period, in 305 fellow eyes (40.1%) predisposing retinal lesions were present and prophylactic treatments (photocoagulation, cryotherapy or scleral buckle) were performed independently of vitreous status. The results were then compared with the incidence of bilateral RD without prophylaxis reported in Folk and Burton's study of 1982; the two study's data were well matched and showed no significant difference in regards to age, sex, incidence myopia > or =-2.5 and incidence of lattice degeneration. The objective was to investigate whether or not prophylactic treatment is able to avert retinal detachment in the fellow eye. The age of the patients with peripheral retinal lesions was correlated inversely with the presence of myopia. Nine eyes out of 305 eyes treated (2.9%) developed a retinal detachment, reducing the rate of bilateral retinal detachment to 1.2% (9 eyes out of 760). This incidence of bilaterality (1.2%) was lower than the incidence of retinal detachment in fellow eyes not prophylactically treated as reported in the literature, and there exists a highly statistically significant difference between this study's data of 1.2% after prophylaxis and a 13.4% rate of bilaterality as reported by Folk without prophylaxis (P=0.0000).

E-mail: moises.vet@hotmail.com This paper aimed to assess the risk of exposure and conduct of prophylactic antirrabies treatment established by health care providers and the endemics Municipality of Garanhuns, PE during their professional activities. We conducted a descriptive epidemiological study of retrospective type, from data collection through the application of a semi-structured questionnaire containing open and closed questions, to 192 professionals, 168 health agents and 24 agents of the municipality of endemics Garanhuns -PE. Of the 192 interviewed agents, 14.1% (27/165 had been attacked by animals during their occupation activities. On the post-exposure prophylactic treatment, it was found that 44.5% (12/27 received-vaccination serum, 37% (10/27 did not undergo any treatment, while only 18.5% (5/27 had the wound washed with soap and water. Was concluded that there is a lack of basic information regarding both the pre-exposure or post-exposure prophylaxis of rabies in professionals like agents that act with both health and / or endemic diseases and it is suggested both the improvement of their professional skills as the preexposure immunization as prophylactic measure to minimize the occupational risk in function of their field activities.

    People who suffer from headaches often prefer nutraceutical treatment over traditional pharmacological approaches, due to fear of possible side effects, drug dependence, or addiction. Since treatment with nutraceuticals does not require a doctor's prescription, many patients rely on their own judgment as to when and which one to take, often without consultation or guidance from their physician. Some physicians could provide information about potential efficacy and side effects of various products, but many are not familiar with the nutraceuticals. Widespread skepticism persists among doctors about the effectiveness of these treatments. This is largely due to the lack of rigorous clinical studies. However, even when incontrovertible scientific evidence exists, many physicians remain distrustful of the evidence. The following review summarizes randomized controlled trials of some of the most commonly used non-pharmacological treatments, including magnesium, coenzyme Q10, riboflavin (vitamin B2), petasites, and feverfew (Table 1).

    Women who test positive for a BRCA1/2 mutation face difficult choices to manage their breast cancer risk; one of these choices is whether to opt for prophylactic mastectomy. Few data are available about this decision-making process. The current study provides data regarding the stability of risk-management preferences over time and the factors that are associated with these preferences. We analyzed data from 338 women who opted for breast cancer antigen (BRCA) testing. First, we prospectively assessed preferences of 80 BRCA mutation carriers at five different points in time ranging from 1 week after blood sampling up to 9 months after BRCA-test disclosure. Second, we applied univariate and multivariate regression analyses to examine which medical, sociodemographic, and psychological factors are related to a preference for prophylactic mastectomy. Ninety percent of the women already indicated a preference regarding risk management at baseline. Moreover, most women had stable preferences over time. Furthermore, anticipated feelings of regret in case of a hypothetical breast cancer diagnosis in the near future were strongly related to risk-management preference (odds ratio = 8.93; P preferences. Many of them may be sensitive to the possibility of regret in case of a bad outcome. We discuss whether possible regret in the future is a rational reason for opting for prophylactic mastectomy, or whether it signifies an emotional coping process or strategy in which the future costs are no longer fully considered.

    Two prospective trials have demonstrated prophylactic antimuscarinics following prostatectomy reduce pain from bladder spasms. Our practice adopted the routine administration of prophylactic belladonna and opium (B&O) suppositories to patients undergoing robotic assisted laparoscopic radical prostatectomy (RALP). The aim of this study is to determine if this change in clinical practice was associated with improvement of postoperative outcomes. The medical records of 202 patients that underwent RALP surgery who were or were not administered prophylactic B&O suppositories in the immediate postoperative period were abstracted for duration of anesthesia recovery, pain and analgesic use. Patient and surgical characteristics between groups were similar except B&O group were slightly older (p = 0.04) and administered less opioid analgesics (p = 0.05). There was no difference between groups in the duration of phase I recovery from anesthesia (p = 0.96). Multivariable adjustments for age, body mass index, American Society of Anesthesiologists physical status, and surgical duration were made, and again it was found that suppository administration had no association with phase I recovery times (p = 0.94). The use of antimuscarinic medication for bladder spams in the B&O group was less during phase I recovery (p suppositories at the immediate conclusion of RALP surgery was not associated with improvements of the postoperative course.

    During a 4-year period, 1978-1981, 312 patients were operated on for unilateral rhegmatogenous detachment of the retina. Of the fellow eyes, 11% showed moderate (VA 0.15-0.4) and 5% severe (VA less than or equal to 0.1) visual impairment. Of the fellow eyes 49% were myopic (- 1.0 D. or more), and aphakia was present in 14%. Details of the peripheral fundus were adequately recordable for 260 fellow eyes. Degenerations considered to predispose to retinal detachment were found in 98 eyes (38%): lattice degeneration in 54 (21%), granular tuft in 17 (7%), retinal tear(s) in 12 (5%), and retinoschisis in 15 (6%). Prophylactic treatment of predisposing degenerations was performed in 91 of the 98 eyes using cryo- or photocoagulation (argon laser). No intra- or permanent post-operative complications were noticed. One of the treated fellow eyes (1.1%) detached 10 months after prophylactic treatment due to new tears. In the untreated group, 6 of the 221 eyes detached (2.7%). The difference was not statistically significant, but the groups were not comparable because 93% of the eyes showing predisposing degenerations were treated. None of the eyes treated for retinal breaks or lattice degeneration has detached. In these cases prophylactic treatment of the fellow eye is recommended. In most eyes cryocoagulation seems to be preferable to photocoagulation.

    Data on the current burden of adenocarcinoma (ADC) and histology-specific human papillomavirus (HPV) type distribution are relevant to predict the future impact of prophylactic HPV vaccines. We estimate the proportion of ADC in invasive cervical cancer, the global number of cases of cervical ADC in 2015, the effect of cervical screening on ADC, the number of ADC cases attributable to high-risk HPV types -16, -18, -45, -31 and -33, and the potential impact of HPV vaccination using a variety of data sources including: GLOBOCAN 2008, Cancer Incidence in Five Continents (CI5) Volume IX, cerv
