    Zimbabwe is a land-locked plateau country of 151,000 square miles, divided into 8 provinces, in Southeastern Africa, bordered by South Africa, Botswana, Zambia and Mozambique. Its population consists of 8.8 million blacks, divided between the Shona-speaking Mashona (80%) and the Sindebele-speaking Matabele (19%), 100,000 whites, 20,000 coloreds, and 10,000 Asians. Many of the blacks are Christians. More than 1/2 the whites migrated to Zimbabwe after the Second World War at a rate of about 1000 a year until the mid-1970s; since then 12,000 whites have left the country. The official language is English, and education is free. Most African children 5-19 years old attend school, and literacy is between 40% and 50%. The University of Zimbabwe is located in Harare, the capital, and there are several technical institutes and teacher-training colleges. Zimbabwe has been inhabited since the stone age, and evidence of a high indigenous civilization remains in the "Great Zimbabwe Ruins" near Masvingo. The present black population is descended from later migrations of Bantu people from central Africa. Cecil Rhodes was granted concessions for mineral rights in the area in 1888, and the territory, which administered by the British South Africa Company, was called Rhodesia. Southern Rhodesia became a self-governing entity within the British Empire in 1913. In 1953 Southern Rhodesia was joined with the British protectorates of Northern Rhodesia and Nyasaland in the Central African Federation, but this dissolved in 1963, and Northern Rhodesia and Nyasaland became independent as Zambia and Malawi in 1964. Independence was withheld from Rhodesia because Prime Minister Ian Smith refused to give Britain assurances that the country would move toward majority rule. In 1965 Smith issued a Unilateral Declaration of Independence (UDI) from the UK. In 1966 the UN Security Council imposed mandatory economic sanctions on Rhodesia. Within Rhodesia the major African nationalist groups -- the

    Although the current literature discusses mesh complications including pain, as well as suggesting different techniques for removing mesh, there is little literature regarding pain outcomes after surgical removal or revision. The purpose of this study is to determine if surgical removal or revision of vaginal mesh improves patient's subjective complaints of pelvic pain associated with original placement of mesh. After obtaining approval from the Vanderbilt University Medical Center Institutional Review Board, a retrospective review of female patients with pain secondary to previous mesh placement who underwent excision or revision of vaginal mesh from January 2000 to August 2012 was performed. Patient age, relevant medical history including menopause status, previous hysterectomy, smoking status, and presence of diabetes, fibromyalgia, interstitial cystitis, and chronic pelvic pain, was obtained. Patients' postoperative pain complaints were assessed. Of the 481 patients who underwent surgery for mesh revision, removal or urethrolysis, 233 patients met our inclusion criteria. One hundred and sixty-nine patients (73 %) reported that their pain improved, 19 (8 %) reported that their pain worsened, and 45 (19 %) reported that their pain remained unchanged after surgery. Prior history of chronic pelvic pain was associated with increased risk of failure of the procedure to relieve pain (OR 0.28, 95 % CI 0.12-0.64, p = 0.003). Excision or revision of vaginal mesh appears to be effective in improving patients' pain symptoms most of the time. Patients with a history of chronic pelvic pain are at an increased risk of no improvement or of worsening pain.

    To describe pregnancy outcomes among HIV-infected women and examine factors associated with live birth among those receiving and not receiving combination antiretroviral therapy (cART). The present analysis included women with HIV from Uganda and Zimbabwe who participated in a prospective cohort study during 2001-2009. Incident pregnancies and pregnancy outcomes were recorded quarterly. The Kaplan-Meier method was used to estimate incident pregnancy probabilities; factors associated with live birth were evaluated by Poisson regression with generalized estimating equations. Among 306 HIV-infected women, there were 160 incident pregnancies (10.1 per 100 women-years). The pregnancy rate was higher among cART-naïve women than among those receiving cART (10.7 vs 5.5 per 100 women-years; P=0.047), and it was higher in Uganda than in Zimbabwe (14.4 vs 7.7 per 100 women-years; Ppregnancy (relative risk 0.8; 95% confidence interval 0.7-1.0). Women not receiving cART have higher pregnancy rates than do those receiving cART, but cART use might not affect the risk of adverse pregnancy outcomes. Timely prenatal care and monitoring of illnesses during pregnancy should be incorporated into treatment services for HIV-infected women.

    Preoperative teaching is an important part of patient care and can prevent complications, as well as promote patient fulfillment during hospitalization. A study was conducted at Alton Ochsner Medical Foundation in New Orleans, LA, in 1989, to determine the impact of a preoperative teaching program on the incidence of postoperative atelectasis and patient satisfaction. Results showed no significant difference of postoperative complications and patient gratification after participating in a structured preoperative teaching program. As part of this study, it was identified that a patient evaluation tool for a preoperative teaching class needed to be developed. The phases of this process are explained in the following article.

    The government of Zimbabwe began providing antiretroviral therapy (ART) to People Living with HIV/AIDS (PLHIV) in public institutions in 2004. In Midlands province two clinics constituted the most active HIV care service points, with patients being followed up through a comprehensive patient monitoring and tracking system which captured specific patient variables and outcomes over time. The data from 2006 to 2011 were subjected to analysis to answer specific research questions and this case study is based on that analysis. The goal of this case study is to build participants' capacity to undertake secondary data analysis and interpretation using a dataset for HIV antiretroviral therapy in Zimbabwe and to draw conclusions which inform recommendations. Case studies in applied epidemiology allow students to practice applying epidemiologic skills in the classroom to address real-world public health problems. Case studies as a vital component of an applied epidemiology curriculum are instrumental in reinforcing principles and skills covered in lectures or in background reading. The target audience includes Field Epidemiology and Laboratory Training Programs (FELTPs), university students, district health executives, and health information officers.

    Full Text Available Pulmonary artery thromboendarterectomy (PTE has been regarded as a promising, potentially curative surgical procedure. However, PTE is associated with specific postoperative complications, such as reperfusion pulmonary edema and right heart failure leading to a considerable mortality of 7-24%. Despite its limitations PTE is a better surgical alternative to lung transplantation which carries high morbidity and mortality. The aim of the study is to analyze the efficacy, safety, morbidity and survival associated in the postoperative period and quality of life after six months of PTE in Indian patients. Forty-one patients with surgically correctable chronic thromboembolic pulmonary hypertension underwent pulmonary endarterectomy. All patients were in New York Heart Association (NYHA Class II, III or IV. Preoperative mean pulmonary artery pressure was 40.98 ± 9.29 mmHg and mean pulmonary vascular resistance was 418.39 ± 95.88 dynes/sec/cm -5 . All patients were followed up to six months and a telephonic survey was conducted using a standard questionnaire. They were assessed and classified as per NYHA grading. There was a significant reduction in the mean pulmonary artery pressure (from 40.98 ± 9.29 mmHg to 24.13 ± 7.36 mmHg, P < 0.001 and pulmonary vascular resistance (from 418.39 ± 95.88 dynes/sec/cm -5 to 142.45 ± 36.27 dynes/sec/cm -5 , P < 0.001 with a concomitant increase in the cardiac index (from 1.99 ± 0.20 L/min/m 2 to 3.28 ± 0.56 L/min/m 2 , P < 0.001 during the postoperative period. The mortality rate in our study was 12.19% (five patients. Ninety per cent of the patients reported a significant improvement in the quality of life and exercise tolerance after surgery compared to the preoperative state. Pulmonary endarterectomy is an effective and potentially curative surgical treatment for patients with severe chronic thromboembolic pulmonary hypertension. The current techniques of operation make the procedure relatively safe and

    The importance of patient casemix as a determinant of surgical outcome is now being recognized. The present study was undertaken in order to compare the presentation and outcomes in colorectal patients managed surgically by the same surgeon, in the same way, in different settings. Colorectal outcome data from the University Department of Surgery in Wellington and the King Faisal Specialist Hospital in Riyadh were analysed in order to determine casemix differences between the two hospitals. Data relating to the type of surgery, the surgeon, the patient's disease, the operation performed and the postoperative complications were compared. Specific colorectal clinical indicators were compared for two commonly performed operations for rectal cancer: anterior resection and abdomino-perineal resection of the rectum. Wellington patients were slightly older and there were more females. Emergency surgery was more frequent in Wellington. Left hemicolectomy, sigmoid colectomy, abscess drainage and pilonidal surgery were more common in Wellington whereas abdomino-perineal resection and anterior resection of the rectum, stoma closure, fistula surgery, seton insertion, restorative proctocolectomy and ileostomy were undertaken more frequently in Riyadh. More complex anal fistulas were managed in Riyadh. Condylomata accuminata, pilonidal abscess, anorectal abscess, rectal prolapse and diverticular disease were rarely seen in Riyadh. There were more postoperative pulmonary and cardiac complications in Wellington. Patients having anterior resection of the rectum were younger in Riyadh and there were proportionally more females. There were some obvious numerical outcome differences in postoperative atelectasis, wound infection, anastomotic leak and deep vein thrombosis rates but none of these reached statistical significance except atelectasis. In Riyadh the usual male-to-female ratio of patients undergoing abdomino-perineal resection was reversed but, again, none of the numerical

    To evaluate the intraoperative performance and postoperative outcomes after microcoaxial phacoemulsification. Iladevi Cataract & IOL Research Centre, Ahmedabad, India. A prospective observational case series comprised 84 eyes with age-related uncomplicated cataract having microcoaxial phacoemulsification through a 2.2 mm clear corneal incision by a standard surgical technique. Phacoemulsification parameters (Infiniti Vision System, Alcon) were microburst width, 30 ms; preset power, 50%; vacuum, 650 mm Hg; aspiration flow rate, 25 cc/minute. A single-piece Alcon AcrySof intraocular lens was implanted with the C cartridge (Alcon) cartridge. The incision was measured at the end of surgery. Observations included surgical time (from commencement of sculpting to end of epinucleus removal), cumulative dissipated energy (CDE), wound burns, intraoperative complications, postoperative increase in mean central corneal thickness (CCT) at 1 day and 1 month, mean % decrease in endothelial cell density (ECD), absolute mean change in coefficient of variation (cv) 3 months, and uncorrected visual acuity (UCVA) at 1 day. Data were analyzed using a 1-sample t test with 95% confidence intervals (CIs). The mean follow up was 3 months +/- 0.3 (SD). The mean incision size at the end of surgery was 2.3 +/- .09 mm; mean surgical time, 4.5 +/- 1.5 minutes; and mean CDE, 2.3 +/- 2.2 seconds. No wound burns or other intraoperative complications occurred. The postoperative CCT increased by a mean of 16 microm at 1 day (95% CI, 8-25; P = .66;) and by a mean of 3.14 microm at 1 month (95% CI, 2.26-4.05; P = .92). The ECD decreased by a mean of 5.8% (95% CI, 6.8-3.5; P = .82) and the mean coefficient of variation, by 3.3 (95% CI, 4.5-2.0; P = .65). At 1 day, the UCVA was 20/20 in 29% of cases, 20/20 to 20/40 in 58%, and 20/40 to 20/50 in 12%. Microcoaxial phacoemulsification was safely and effectively performed, achieving consistent and satisfactory postoperative outcomes.

    Haematocrit has been studied as an outcome predictor. The aim of this study was to evaluate the correlation between low haematocrit at surgical intensive care unit admission and high disease scoring system score and early outcomes. This retrospective study included 4398 patients admitted to the surgical intensive care unit between January 2006 and July 2013. Acute physiology and chronic health evaluation and simplified acute physiology score II values were calculated and all variables entered as parameters were evaluated independently. Patients were classified as haematocrit if they had a haematocrit < 30% at surgical intensive care unit admission. The correlation between admission haematocrit and outcome was evaluated by univariate analysis and linear regression. A total of 1126 (25.6%) patients had haematocrit. These patients had higher rates of major cardiac events (4% vs 1.9%, p < 0.001), acute renal failure (11.5% vs 4.7%, p < 0.001), and mortality during surgical intensive care unit stay (3% vs 0.8%, p < 0.001) and hospital stay (12% vs 5.9%, p < 0.001). A haematocrit level < 30% at surgical intensive care unit admission was frequent and appears to be a predictor for poorer outcome in critical surgical patients. Patients with haematocrit had longer surgical intensive care unit and hospital stay lengths, more postoperative complications, and higher surgical intensive care unit and hospital mortality rates.

    Postoperative delirium (POD) in Surgical Intensive Care patients is an important independent outcome determinant. The purpose of our study was to evaluate the incidence and determinants of POD. Prospective cohort study conducted during a period of 10 months in a Post-Anesthesia Care Unit (PACU) with five intensive care beds. All consecutive adult patients submitted to major surgery were enrolled. Demographic data, perioperative variables, length of stay (LOS) and the mortality at PACU, hospital and at 6-months follow-up were recorded. Postoperative delirium was evaluated using the Intensive Care Delirium Screening Checklist (ICDSC). Descriptive analyses were conducted and the Mann-Whitney test, Chi-square test or Fisher's exact test were used for comparisons. Logistic regression analysis evaluated the determinants of POD with calculation of odds ratio (OR) and its confidence interval 95% (95% CI). There were 775 adult PACU admissions and 95 patients had exclusion criteria. Of the remaining 680 patients, 128 (18.8%) developed POD. Independent determinants of POD identified were age, ASA-PS, emergency surgery and total amount of fresh frozen plasma administered during surgery. Patients with delirium had higher mortality rates, were more severely ill and stayed longer at the PACU and in the hospital. POD was an independent risk factor for hospital mortality There was a high incidence of delirium had a high incidence in intensive care surgical patients. POD was associated with worse severity of disease scores, longer LOS in hospital, and in PACU and higher mortality rates. The independent risk factors for POD were age, ASAPS, emergency surgery and the amount of plasma administered during surgery. Copyright © 2012 Elsevier Editora Ltda. All rights reserved.

    Full Text Available BACKGROUND Cataract formation is commonly observed as a result of blunt or penetrating ocular injury and constitutes one of major causes of acute or longstanding visual loss. The surgical technique, timing of surgery and postoperative complications have all been considered to be significant factors in determining the final visual outcome. The aim of the present study is to evaluate postoperative visual outcome in a series of patients with traumatic cataract and to assess the postoperative complications conducted at IQ City Medical College, Durgapur, West Bengal. MATERIALS AND METHODS A consecutive series of 45 patients with traumatic cataract were carefully selected from outpatient department between May 2015 and April 2017. All the patients had undergone manual Small Incision Cataract Surgery (SICS with IOL implantation. Postoperative visual outcome and postoperative complications were assessed. RESULTS Corrected Visual Acuity (VA at the end of 6th week in 45 cases ranged between 6/6 and 6/60. Subjective correction with glasses ranged from -2 dioptre spherical to +1.5 dioptre spherical. 25 cases (55.5% had VA 6/6-6/9, 15 cases (33.3% had VA of 6/12 to 6/18, 4 cases (8.9% had VA between 6/24 and 6/36 and 1 case had VA 6/60. The group which had VA between 6/12 and 6/18 was due to the presence of posterior capsular opacification. CONCLUSION The present study reveals most of the traumatic cataract cases had favourable visual outcome. Considering the fact that a good number of paediatric patients were treated in this study, it assumes more significance with the favourable visual outcome that could be achieved, thus preventing deprivation amblyopia and blindness.

    We evaluated postoperative outcomes in patients who have lumbar foraminal or extraforaminal disc herniation (FELDH) and suggested the risk factors for poor outcomes. A total of 234 patients were selected for this study. Pre- and post-operative Visual Analogue Scale (VAS) and Korean version Oswestry Disability Index (KODI) were evaluated and the changes of both score were calculated. Outcome was defined as excellent, good, fair, and poor based on Mcnab classification. The percentage of superior facetectomy was calculated by using the Maro-view 5.4 Picture Archiving Communication System (PACS). Paramedian lumbar discectomy was performed in 180 patients and combined lumbar discectomy was performed in 54 patients. Paramedian lumbar discectomy group showed better outcome compared with combined discectomy group. p value of VAS change was 0.009 and KODI was 0.013. The average percentage of superior facetectomy was 33% (range, 0-79%) and it showed negative correlation with VAS and KODI changes (Pearson coefficient : -0.446 and -0.498, respectively). Excellent or good outcome cases (Group I) were 136 (58.1%) and fair or poor outcome cases (Group II) were 98 (41.9%). The percentage of superior facetectomy was 26.5% at Group I and 42.5% at Group II. There was significant difference in superior facetectomy percentage between Group I and II (p=0.000). This study demonstrated that paramedian lumbar discectomy with preservation of facet joints is an effective and good procedure for FELDH. At least 60% of facet should be preserved for excellent or good outcomes.

    Brain natriuretic peptide (BNP) is a cardiac neurohormone known to correlate with left ventricular (LV) dilation, decreased contractility, and increased stiffness. Consequently, BNP has been used as a prognostic tool to assess the degree of LV unloading for patients supported by continuous-flow LV assist devices (LVADs). We assessed the prognostic value of changes in BNP in the 2 weeks after LVAD implantation. This retrospective study analyzed laboratory findings and outcomes of 189 LVAD patients. Patients were separated into two groups based on whether serum BNP levels had improved from preoperative levels by postoperative day 14. Group 1 had improvement in BNP levels, whereas group 2 had no improvement or worsening in BNP. There were no significant differences between the groups in age, gender, race, body mass index, or comorbidities. Group 1 had preoperative BNP 1,125 ± 1,078.3 pg/dl and postoperative BNP 440.2 ± 267.7 pg/dl (ΔBNP = -693.09 ± 942.4 pg/dl), whereas group 2 had preoperative BNP 346.0 ± 309.1 pg/dl and postoperative BNP 631.57 ± 483.4 pg/dl (ΔBNP = 289.32 ± 329.7 pg/dl). Postoperative survival in group 2 was significantly worse than in group 1. Rates of right ventricular failure (RVF) were significantly higher in group 2 (group 1: 39%, group 2: 52.7%; p = 0.01). In most patients implanted with a LVAD, BNP improves significantly in the postoperative period as the LV is unloaded. Our results indicate that lack of improvement in postoperative BNP is associated with longer length of stay, increased rates of RVF, and is an independent risk factor for reduced postoperative survival.

    Traditionally, hallux valgus operative correction has been accompanied by serial spica taping of the great toe during the postoperative period. We retrospectively reviewed 187 adult patients who underwent proximal first metatarsal osteotomy with a modified McBride procedure in 2008-2009 (n = 83) and 2011-2012 (n = 104). Postoperatively, to maintain the corrected position of the hallux, patients from 2008 through 2009 underwent weekly spica taping, while patients from 2011 through 2012 utilized a toe separator. The hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured using anteroposterior weight-bearing preoperative, 2-week postoperative non-weight-bearing, and 3-month weight-bearing final follow-up radiographs. A mixed-effects linear regression model identified differences between the treatment groups over time, and a t test compared actual radiographic differences at final follow-up. The mixed-effects model revealed no significant difference in the HVA over time when comparing patients taped to those not taped at the preoperative (33 ± 6 vs 33 ± 6), 2-week postoperative (10 ± 7 vs 9 ± 6), and 3-month follow-up (14 ± 6 vs 11 ± 7) visits (P = .08). At final follow-up, the HVA was lower for the group that was not taped, but the difference (2.5 degrees) was below the minimal clinically important difference (MCID) (P = .015, 95% CI 0.5-4.5). For IMA, there was improved maintenance of correction over time in the patients that were not taped compared to those taped at the preoperative (15 ± 3 vs 15 ± 3), 2-week postoperative (2 ± 2 vs 3 ± 3), and 3-month follow-up (5 ± 4 vs 7 ± 4) visits (P = .002). At final follow-up, the IMA was lower for the group that was not taped, but the difference (1.7 degrees) was below the MCID (P = .004, 95% CI 0.7-2.9). We report no radiographic benefit of postoperative taping after hallux valgus correction. The present study challenges the previous dogma of postoperative spica taping as the protocol is cost and

    Poor nutrition status is considered a risk factor for postoperative complications in the adult population. In elderly patients, who often have a poor nutrition status, this relationship has not been substantiated. Thus, the aim of this systematic review was to assess the merit of preoperative nutrition parameters used to predict postoperative outcome in elderly patients undergoing general surgery. A systematic literature search of 10 consecutive years, 1998-2008, in PubMed, EMBASE, and Cochrane databases was performed. Search terms used were nutrition status, preoperative assessment, postoperative outcome, and surgery (hip or general), including their synonyms and MeSH terms. Limits used in the search were human studies, published in English, and age (65 years or older). Articles were screened using inclusion and exclusion criteria. All selected articles were checked on methodology and graded. Of 463 articles found, 15 were included. They showed profound heterogeneity in the parameters used for preoperative nutrition status and postoperative outcome. The only significant preoperative predictors of postoperative outcome in elderly general surgery patients were serum albumin and ≥ 10% weight loss in the previous 6 months. This systematic review revealed only 2 preoperative parameters to predict postoperative outcome in elderly general surgery patients: weight loss and serum albumin. Both are open to discussion in their use as a preoperative nutrition parameter. Nonetheless, serum albumin seems a reliable preoperative parameter to identify a patient at risk for nutrition deterioration and related complicated postoperative course.

    To compare postoperative outcomes in children undergoing cardiac surgery during the viral respiratory season and nonviral season at our institution. This was a retrospective cohort study and secondary matched case-control analysis. The setting was an urban academic tertiary-care children's hospital. The study was comprised of all patients <18 years of age who underwent cardiac surgery at Johns Hopkins Hospital from October 2002 through September 2007. Patients were stratified by season of surgery, complexity of cardiac disease, and presence or absence of viral respiratory infection. Measurements included patient characteristics and postoperative outcomes. The primary outcome was postoperative length of stay (LOS). A total of 744 patients were included in the analysis. There was no difference in baseline characteristics or outcomes, specifically, no difference in postoperative LOS, intensive care unit (ICU) LOS, and mortality, among patients by seasons of surgery. Patients with viral respiratory illness were more likely to have longer postoperative LOS (p < 0.01) and ICU LOS (p < 0.01) compared with matched controls. We identified no difference in postoperative outcomes based on season in patients undergoing cardiac surgery. Children with viral respiratory infection have significantly worse outcomes than matched controls, strengthening the call for universal administration of influenza vaccination and palivizumab to appropriate groups. Preoperative testing for respiratory viruses should be considered during the winter months for children undergoing elective cardiac surgery.

The correlations between the intelligence scores and 1-2 years postoperative Categories of Auditory Performance (CAP scores and between subscales of performance and 1-2 years postoperative CAP scores were analyzed. Results. There was no correlation between the categories of verbal intelligence quotient (IQ and performance IQ for “mentally retarded” and “average,” respectively (Spearman’s rho = 0.42, P=0.15. There was a strong correlation between performance IQ and the postoperative CAP scale (Spearman’s rho = 0.8977, P=0.0008. “Picture arrangement” and “picture completion,” reflecting social cognition, were strongly correlated with the postoperative CAP scales. Conclusion. Performance intelligence, especially social cognition, was strongly related to the postoperative CI outcome of cochlear implant users. Therefore, auditory rehabilitation, including social rehabilitation, should maximize the postoperative CI outcomes.

    Full Text Available To investigate the relationship between preoperative expectations and actual postoperative outcomes of visual function (VF among patients undergoing first eye cataract surgery.A longitudinal study of 182 patients from hospitals in urban Southern China were surveyed prior to surgery and 3 month after cataract surgery regarding their preoperative, expected postoperative and actual postoperative VF for each of the items on the Catquest-9SF and their satisfaction with cataract surgery. In addition, detailed clinical data were collected preoperatively and postoperatively.The majority of cataract patients in urban Southern China had high expectations for VF outcomes after cataract surgery and in most cases postoperative outcomes achieved the expected level of improvement. The mean (standard deviation, SD preoperative Catquest-9SF score was 15.7 (5.86 and the mean (SD expected postoperative score was 26.3 (2.93. The discrepancy between actual and expected improvement was significantly correlated with patients' health literacy, presence of systemic and ocular comorbidity, preoperative visual acuity of the surgery eye, LOCS III nuclear opalescence and cortical cataract grading.Cataract patients in urban Southern China had high expectations for surgery outcomes. Patients with low level of health literacy and the presence of systemic and ocular comorbidity may need a comprehensive counseling to decrease the discrepancy regarding expected and actual outcomes.

    The impact of early enteral nutrition (EEN) on clinical outcomes of gastric cancer patients was investigated. Three hundred pa-tients undergoing gastric cancer surgery from July 2010 to May 2014 were randomly divided into experimental and control groups (n = 150/group). Experimental group patients received enteral nutrition in water during the early postoperative period. Control group patients received conventional perioperative treatment. Patients' clinical outcomes, post-operative immune function, and nutritional statuses were compared, which revealed that the postoperative fever duration (80.2 ± 6.0 vs 88.1 ± 8.1 h, P 0.05]. At postoperative days 3 and 7, the CD3(+), CD4(+), natural killer cell, albumin, and prealbumin levels and CD4(+)/CD8(+) ra-tio were significantly higher in the experimental group than the control group (all P nutritional status and immune function and promote early recovery of intestinal function in patients with gastric cancer.

    Head and neck cancer patients treated with surgery often experience significant postoperative morbidities. Administering preoperative nutritional intervention may improve surgical outcomes, but there is currently a paucity of data reviewing the association between preoperative nutritional status and postoperative outcome. It is therefore of importance to investigate this association among head and neck cancer patients. To assess the association between preoperative nutritional status and postoperative outcome in head and neck cancer patients treated with surgery, a retrospective study of 70 head and neck cancer patients who were surgically treated between 2013 and 2014 in a tertiary referral head and neck surgery center in Hong Kong was conducted. Clinical data regarding preoperative nutritional status and postoperative outcome were retrieved from a computer record system. Logistic and linear regressions were used to analyze the appropriate parameters. A higher preoperative albumin level was associated with lower rates of postoperative complications and better wound healing (P cancer patients, preoperative intervention strategies that boost albumin levels could be considered for improving surgical outcome.

    Tibial plateau fractures are complex and the current evidence for postoperative rehabilitation is weak, especially related to the recommended postoperative weight bearing. The primary aim of this study was to investigate if loading in the first 12 weeks of recovery is associated with patient reported outcome measures at 26 and 52 weeks postoperative. We hypothesized that there would be no association between loading and patient reported outcome measures. Seventeen patients, with a minimum of 52-week follow-up following fragment-specific open reduction and internal fixation for tibial plateau fracture, were selected for this retrospective analysis. Postoperatively, patients were advised to load their limb to a maximum of 20kg during the first 6 weeks. Loading data were collected during walking using force platforms. A ratio of limb loading (affected to unaffected) was calculated at 2, 6 and 12 weeks postoperative. Knee Injury and Osteoarthritis Scores were collected at 6, 12, 26 and 52 weeks postoperative. The association between loading ratios and patient reported outcomes were investigated. Compliance with weight bearing recommendations and changes in the patient reported outcome measures are described. Fracture reduction and migration were assessed on plain radiographs. No fractures demonstrated any measurable postoperative migration at 52 weeks. Significant improvements were seen in all patient reported outcome measures over the first 52 weeks, despite poor adherence to postoperative weight bearing restrictions. There were no associations between weight bearing ratio and patient reported outcomes at 52 weeks postoperative. Significant associations were identified between the loading ratio at 2 weeks and knee-related quality of life at six months (R 2 =0.392), and between the loading ratio at 6 weeks combined with injury severity and knee-related quality of life at 26 weeks (R 2 =0.441). In summary, weight bearing as tolerated does not negatively affect the

    Full Text Available Cataract surgery is one of the most successful and frequently performed operations worldwide, and yet cataract remains the commonest cause of global blindness. This is in part due to the shortage and uneven distribution of trained personnel in some countries. More worryingly, a high rate of cataract blindness also reflects poor visual outcomes after surgery, as has been documented in many RAAB (rapid assessment of avoidable blindness studies.

    Subarachnoid hemorrhage (SAH) results in significant morbidity and mortality, even among patients who reach medical attention in good neurological condition. Many patients have neurological decline in the perioperative period, which contributes to long-term outcomes. The focus of this study is to characterize the incidence of, characteristics predictive of, and outcomes associated with acute postoperative neurological deterioration in patients undergoing surgery for ruptured intracranial aneurysm. The Intraoperative Hypothermia for Aneurysm Surgery Trial (IHAST) was a multicenter randomized clinical trial that enrolled 1001 patients and assesssed the efficacy of hypothermia as neuroprotection during surgery to secure a ruptured intracranial aneurysm. All patients had a radiographically confirmed SAH, were classified as World Federation of Neurosurgical Societies (WFNS) Grade I-III immediately prior to surgery, and underwent surgery to secure the ruptured aneurysm within 14 days of SAH. Neurological assessment with the National Institutes of Health Stroke Scale (NIHSS) was performed preoperatively, at 24 and 72 hours postoperatively, and at time of discharge. The primary outcome variable was a dichotomized scoring based on an IHAST version of the Glasgow Outcome Scale (GOS) in which a score of 1 represents a good outcome and a score > 1 a poor outcome, as assessed at 90-days' follow-up. Data from IHAST were analyzed for occurrence of a postoperative neurological deterioration. Preoperative and intraoperative variables were assessed for associations with occurrence of postoperative neurological deterioration. Differences in baseline, intraoperative, and postoperative variables and in outcomes between patients with and without postoperative neurological deterioration were compared with Fisher exact tests. The Wilcoxon rank-sum test was used to compare variables reported as means. Multiple logistic regression was used to adjust for covariates associated with occurrence

    The predictive role of patient-specific characteristics and radiographic parameters on medial unicompartmental knee arthroplasty (UKA) outcomes is well known, but knowledge of these predictors is lacking in lateral UKA. Therefore, purpose of this study was to assess the predictive role of these parameters on short-term functional outcomes of lateral UKA. In this retrospective cohort study, Western Ontario and McMaster Universities Arthritis Index scores were collected at 2-year follow-up (median 2.2 years, range 2.0-4.0 years) in 39 patients who underwent lateral UKA. Patient-specific characteristics included age, BMI and gender, while radiographic parameters included osteoarthritis severity of all three compartments and both preoperative and postoperative hip-knee-ankle alignment. BMI, gender, age and preoperative valgus alignment were not correlated with functional outcomes, while postoperative valgus alignment was correlated with functional outcomes (0.561; p = 0.001). Postoperative valgus of 3°-7° was correlated with better outcomes than more neutral (-2° to 3° valgus) alignment (96.7 vs. 85.6; p = 0.011). Postoperative alignment was a predictor when corrected for patient-specific characteristics (regression coefficient 4.1; p coefficient 3.8; p = 0.002). Postoperative valgus alignment of 3°-7° was correlated with the best short-term functional outcomes in lateral UKA surgery, while patient-specific parameters and preoperative alignment were not correlated with functional outcomes. Based on these findings, a surgeon should aim for valgus alignment of 3°-7° when performing lateral UKA surgery for optimal functional outcomes. Prognostic study, Level II.

    This study investigated the impact of early enteral nutrition (EEN) on the clinical outcomes of gastric cancer patients after radical gastrectomy. Four hundred gastric cancer patients undergoing radical gastrectomy of any extend with D2 nodal dissection were randomly divided into an experimental and a control group with 200 cases in each group. Patients in the control group received postoperative parenteral nutrition (PN), while patients in the experimental group received postoperative EEN. After treatment, the clinical outcomes, postoperative immune function, and nutritional status of the two groups were evaluated. The postoperative fever time, intestinal function recovery time, anal exhaust time, and the length of hospital stay for patients in the experimental group were significantly shorter than those of the control group. We did not find significant differences in anastomotic leak, postoperative ileus and regurgitation between the two groups. The activities of multiple immune cell types, including CD3⁺, CD4⁺, CD4⁺/CD8⁺, and natural killer (NK) cells, were significantly lower in both groups on postoperative day 1 when compared with the preoperative levels (p0.05). After treatment, levels of CD3⁺, CD4⁺, CD4⁺/CD8⁺, and NK cells in the experimental group patients were 35.6 ± 4.2, 42.2 ± 3.0, 1.7 ± 0.3, and 27.3 ± 5.3%, respectively, on postoperative day 7, which were similar to the preoperative levels. The immune cell levels from the control group patients remained significantly lower when compared with preoperative values; in addition, these values were also significantly lower when compared with the EEN patients (pgastric cancer patients undergoing radical gastrectomy, the clinical outcome, immune function and nutritional status after EEN were significantly improved. These data suggest the widespread use of EEN in clinical practice.

    Postoperative outcome of spinal meningiomas is an important issue in surgery decision-making. There are limited and conflicting data in the literature about the prognostic factors influencing recovery, especially about the histopathologic subtypes. This study was carried out to evaluate the effect of some of these factors on postoperative outcome. This study was performed on 39 patients operated for spinal meningioma between October 1998 and January 2012; their histopathologic subtype was determined according to WHO criteria. The follow up period ranged between 8 - 120 months. The influence of histopathologic subtype, grade, age, sex, surgical approach, local adhesion and anatomical location was assessed according to Frankel classification of neurologic deficit. From a total number of 39 spinal meningiomas, 34 cases were WHO grade I, from which 15 cases were psammomatous, 7 cases were meningothelial, 9 cases were transitional and 3 cases were fibroblastic. Five cases were grade II, 3 of which had clear cell appearance and the remaining 2 had chordoid appearance. The mean age was 51.6 (22 to 76) years; 25 cases were female and 14 cases were male. This study revealed that grade II meningioma cases had poor prognosis in all 5 cases and psammomatous subtype had poor postoperative outcome in 40% of cases while the other subtypes had good outcome in all cases (P = 0.026). Cervical location of the tumor was also related with poor outcome in 37.5% of the cases, while 22.5% had poor outcome in other locations (P = 0.029). Age below and above 45 years and sex had no significant influence on the outcome. Spinal meningiomas of psammomatous type and grade II spinal meningiomas are associated with less favorable postoperative neurologic outcome. Cervical location has also a negative correlation with a good outcome.

    The US medical malpractice system assumes that the threat of liability should deter negligence, but it is unclear whether malpractice environment affects health care quality. We sought to explore the association between state malpractice environment and postoperative complication rates. This observational study included Medicare fee-for-service beneficiaries undergoing one of the following operations in 2010: colorectal, lung, esophageal, or pancreatic resection, total knee arthroplasty, craniotomy, gastric bypass, abdominal aortic aneurysm repair, coronary artery bypass grafting, or cystectomy. The state-specific malpractice environment was measured by 2010 medical malpractice insurance premiums, state average award size, paid malpractice claims/100 physicians, and a composite malpractice measure. Outcomes of interest included 30-day readmission, mortality, and postoperative complications (eg sepsis, myocardial infarction [MI], pneumonia). Using Medicare administrative claims data, associations between malpractice environment and postoperative outcomes were estimated using hierarchical logistic regression models with hospital random-intercepts. Measures of malpractice environment did not have significant, consistent associations with postoperative outcomes. No individual tort reform law was consistently associated with improved postoperative outcomes. Higher-risk state malpractice environment, based on the composite measure, was associated with higher likelihood of sepsis (odds ratio [OR] 1.22; 95% CI 1.07 to 1.39), MI (OR 1.14; 95% CI 1.06 to 1.23), pneumonia (OR 1.09; 95% CI 1.03 to 1.16), acute renal failure (OR 1.15; 95% CI 1.08 to 1.22), deep vein thrombosis/pulmonary embolism (OR 1.22; 95% CI 1.13 to 1.32), and gastrointestinal bleed (OR 1.18; 95% CI 1.08 to 1.30). Higher risk malpractice environments were not consistently associated with a lower likelihood of surgical postoperative complications, bringing into question the ability of malpractice lawsuits to

    Full Text Available To study the predictive value of preoperative magnetic resonance imaging (MRI findings for the two-year postoperative clinical outcome in lumbar spinal stenosis (LSS.84 patients (mean age 63±11 years, male 43% with symptoms severe enough to indicate LSS surgery were included in this prospective observational single-center study. Preoperative MRI of the lumbar spine was performed with a 1.5-T unit. The imaging protocol conformed to the requirements of the American College of Radiology for the performance of MRI of the adult spine. Visual and quantitative assessment of MRI was performed by one experienced neuroradiologist. At the two-year postoperative follow-up, functional ability was assessed with the Oswestry Disability Index (ODI 0-100% and treadmill test (0-1000 m, pain symptoms with the overall Visual Analogue Scale (VAS 0-100 mm, and specific low back pain (LBP and specific leg pain (LP separately with a numeric rating scale from 0-10 (NRS-11. Satisfaction with the surgical outcome was also assessed.Preoperative severe central stenosis predicted postoperatively lower LP, LBP, and VAS when compared in patients with moderate central stenosis (p<0.05. Moreover, severe stenosis predicted higher postoperative satisfaction (p = 0.029. Preoperative scoliosis predicted an impaired outcome in the ODI (p = 0.031 and lowered the walking distance in the treadmill test (p = 0.001. The preoperative finding of only one stenotic level in visual assessment predicted less postoperative LBP when compared with patients having 2 or more stenotic levels (p = 0.026. No significant differences were detected between quantitative measurements and the patient outcome.Routine preoperative lumbar spine MRI can predict the patient outcome in a two-year follow up in patients with LSS surgery. Severe central stenosis and one-level central stenosis are predictors of good outcome. Preoperative finding of scoliosis may indicate worse functional ability.

    Approximately one in every two patients with pharmacoresistant temporal lobe epilepsy will not be rendered completely seizure-free after temporal lobe surgery. The reasons for this are unknown and are likely to be multifactorial. Quantitative volumetric magnetic resonance imaging techniques have provided limited insight into the causes of persistent postoperative seizures in patients with temporal lobe epilepsy. The relationship between postoperative outcome and preoperative pathology of white matter tracts, which constitute crucial components of epileptogenic networks, is unknown. We investigated regional tissue characteristics of preoperative temporal lobe white matter tracts known to be important in the generation and propagation of temporal lobe seizures in temporal lobe epilepsy, using diffusion tensor imaging and automated fibre quantification. We studied 43 patients with mesial temporal lobe epilepsy associated with hippocampal sclerosis and 44 healthy controls. Patients underwent preoperative imaging, amygdalohippocampectomy and postoperative assessment using the International League Against Epilepsy seizure outcome scale. From preoperative imaging, the fimbria-fornix, parahippocampal white matter bundle and uncinate fasciculus were reconstructed, and scalar diffusion metrics were calculated along the length of each tract. Altogether, 51.2% of patients were rendered completely seizure-free and 48.8% continued to experience postoperative seizure symptoms. Relative to controls, both patient groups exhibited strong and significant diffusion abnormalities along the length of the uncinate bilaterally, the ipsilateral parahippocampal white matter bundle, and the ipsilateral fimbria-fornix in regions located within the medial temporal lobe. However, only patients with persistent postoperative seizures showed evidence of significant pathology of tract sections located in the ipsilateral dorsal fornix and in the contralateral parahippocampal white matter bundle

    Nutritional support for surgical care is crucial because hospital malnutrition is rather common. However, low- and middle-income countries have not adequately addressed nutritional management of surgical patients. To highlight need for nutritional management in surgical patients, the present study aimed to describe preoperative nutritional status in patients who underwent gastrointestinal cancer surgery in Vietnam and to investigate the relationship between preoperative malnutrition and adverse outcomes, such as postoperative complications and prolonged length of hospital stay. We reviewed medical records of patients who underwent a major curative surgery for gastrointestinal cancer at the national hospital in Ho Chi Minh City, Vietnam. We identified preoperative malnutrition based on body mass index and serum albumin level, and postoperative complications in the first 30 d postoperative. We estimated the relative influence of malnutrition on complications and length of hospital stay using multivariate regression models. Of 459 eligible patients, 63% had colorectal cancer, 33% gastric cancer, and 4% esophageal cancer. The prevalence of malnutrition was 19%. No patients died during hospitalization; however, 26% developed complications after surgery. The average length of hospital stay was 14 d. After controlling for potential confounders, preoperative malnutrition was associated with an increased risk of postoperative complications (odds ratio = 1.97) and prolonged hospital stay (2.8 d). Preoperative malnutrition affects surgical outcomes among patients with gastrointestinal cancer in Vietnam. We recommend implementing preoperative nutritional interventions to achieve better outcomes among surgical cancer patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To construct, train, and apply an artificial neural network (ANN) system for prediction of different outcome variables of percutaneous nephrolithotomy (PCNL). We calculated predictive accuracy, sensitivity, and precision for each outcome variable. During the study period, all adult patients who underwent PCNL at our institute were enrolled in the study. Preoperative and postoperative variables were recorded, and stone-free status was assessed perioperatively with computed tomography scans. MATLAB software was used to design and train the network in a feed forward back-propagation error adjustment scheme. Preoperative and postoperative data from 200 patients (training set) were used to analyze the effect and relative relevance of preoperative values on postoperative parameters. The validated adequately trained ANN was used to predict postoperative outcomes in the subsequent 254 adult patients (test set) whose preoperative values were serially fed into the system. To evaluate system accuracy in predicting each postoperative variable, predicted values were compared with actual outcomes. Two hundred fifty-four patients (155 [61%] males) were considered the test set. Mean stone burden was 6702.86 ± 381.6 mm 3 . Overall stone-free rate was 76.4%. Fifty-four out of 254 patients (21.3%) required ancillary procedures (shockwave lithotripsy 5.9%, transureteral lithotripsy 10.6%, and repeat PCNL 4.7%). The accuracy and sensitivity of the system in predicting different postoperative variables ranged from 81.0% to 98.2%. As a complex nonlinear mathematical model, our ANN system is an interconnected data mining tool, which prospectively analyzes and "learns" the relationships between variables. The accuracy and sensitivity of the system for predicting the stone-free rate, the need for blood transfusion, and post-PCNL ancillary procedures ranged from 81.0% to 98.2%.The stone burden and the stone morphometry were among the most significant preoperative characteristics that

    Full Text Available BACKGROUND Abdominal hysterectomy is one of the most frequently performed surgical procedures in women. The non-ambulatory postoperative period is a high risk period for the development of various complications like wound infection, venous stasis, lower respiratory infection, secondary haemorrhage, deep vein thrombosis, pulmonary embolism, paralytic ileus etc. Prolonged surgery, delayed ambulation and not feeding the patient within 48 hours of surgery are often associated with post-operative morbidity and mortality. This study aims to assess the effectiveness of Scheduled Ambulation on early post-operative outcome among patients undergone abdominal hysterectomy by introduction of Scheduled Ambulation from second day of surgery. MATERIALS AND METHODS Method used is quantitative and quasi experimental post-test control method. Scheduled ambulation technique and pattern were taught pre operatively to 35 patients consecutively selected from general and post-operative ward who formed the experimental group. They were given scheduled ambulation from second to fifth post-operative days and results analysed. Another 35 patients taken as control were given the routine post-operative care. Data Analysis- was performed using SPSS version 17.0. Between group comparisons, quantitative variables analysed by Chisquare test p value >0, 05 considered significant. RESULTS The indication of hysterectomy was fibroid uterus in 80% of the control group and 88, 6% of the experimental group. 51.4% of the hysterectomies were encountered in the age group 40-49 years. There was a statistically significant reduction in the severity of pain, fatigue, postural hypotension and risk for developing Deep vein thrombosis in the experimental group on practicing Scheduled Ambulation from second to fifth post-operative days. CONCLUSION Scheduled ambulation helped the abdominal hysterectomy patients to recover from fatigue, pain, postural hypotension and risk for Deep vein thrombosis

    INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39–79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p=0.005 and p=0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p=0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

    PAIN OUT is a European Commission-funded project aiming at improving postoperative pain management. It combines a registry that can be useful for quality improvement and research using treatment and patient-reported outcome measures. The core of the project is a patient questionnaire-the International Pain Outcomes questionnaire-that comprises key patient-level outcomes of postoperative pain management, including pain intensity, physical and emotional functional interference, side effects, and perceptions of care. Its psychometric quality after translation and adaptation to European patients is the subject of this validation study. The questionnaire was administered to 9,727 patients in 10 languages in 8 European countries and Israel. Construct validity was assessed using factor analysis. Discriminant validity assessment used Mann-Whitney U tests to detect mean group differences between 2 surgical disciplines. Internal consistency reliability was calculated as Cronbach's alpha. Factor analysis resulted in a 3-factor structure explaining 53.6% of variance. Cronbach's alpha at overall scale level was high (.86), and for the 3 subscales was low, moderate, or high (range, .53-.89). Significant mean group differences between general and orthopedic surgery patients confirmed discriminant validity. The psychometric quality of the International Pain Outcomes questionnaire can be regarded as satisfactory. The International Pain Outcomes questionnaire provides an instrument for postoperative pain assessment and improvement of quality of care, which demonstrated good psychometric quality when translated into a variety of languages in a large European and Israeli patient population. This measure provides the basis for the first comprehensive postoperative pain registry in Europe and other countries. Copyright © 2013. Published by Elsevier Inc.

    Full Text Available BACKGROUND: Intellectually disabled patients have various comorbidities, but their risks of adverse surgical outcomes have not been examined. This study assesses pre-existing comorbidities, adjusted risks of postoperative major morbidities and mortality in intellectually disabled surgical patients. METHODS: A nationwide population-based study was conducted in patients who underwent inpatient major surgery in Taiwan between 2004 and 2007. Four controls for each patient were randomly selected from the National Health Insurance Research Database. Preoperative major comorbidities, postoperative major complications and 30-day in-hospital mortality were compared between patients with and without intellectual disability. Use of medical services also was analyzed. Adjusted odds ratios using multivariate logistic regression analyses with 95% confidence intervals were applied to verify intellectual disability's impact. RESULTS: Controls were compared with 3983 surgical patients with intellectual disability. Risks for postoperative major complications were increased in patients with intellectual disability, including acute renal failure (odds ratio 3.81, 95% confidence interval 2.28 to 6.37, pneumonia (odds ratio 2.01, 1.61 to 2.49, postoperative bleeding (odds ratio 1.35, 1.09 to 1.68 and septicemia (odds ratio 2.43, 1.85 to 3.21 without significant differences in overall mortality. Disability severity was positively correlated with postoperative septicemia risk. Medical service use was also significantly higher in surgical patients with intellectual disability. CONCLUSION: Intellectual disability significantly increases the risk of overall major complications after major surgery. Our findings show a need for integrated and revised protocols for postoperative management to improve care for intellectually disabled surgical patients.

    We identified factors associated with early and late postoperative seizure control in patients with supratentorial meningioma plus preoperative seizures. In this retrospective study, univariate analysis and multivariate logistic regression analysis compared 24 clinical variables according to the occurrence of early (≤1 week) or late (>1 week) postoperative seizures. Sixty-two of 97 patients (63.9 %) were seizure free for the entire postoperative follow-up period (29.5 ± 11.8 months), while 13 patients (13.4 %) still had frequent seizures at the end of follow-up. Fourteen of 97 patients (14.4 %) experienced early postoperative seizures, and emergence of new postoperative neurological deficits was the only significant risk factor (odds ratio = 7.377). Thirty-three patients (34.0 %) experienced late postoperative seizures at some time during follow-up, including 12 of 14 patients with early postoperative seizures. Associated risk factors for late postoperative seizures included tumor progression (odds ratio = 7.012) and new permanent postoperative neurological deficits (odds ratio = 4.327). Occurrence of postoperative seizures in patients with supratentorial meningioma and preoperative seizure was associated with new postoperative neurological deficits. Reduced cerebral or vascular injury during surgery may lead to fewer postoperative neurological deficits and better seizure outcome.

    As the prevalence of obesity continues to increase, it now includes the growing number of patients with congenital heart disease (CHD). This particular obese patient population may pose additional intraoperative as well as postoperative challenges that may contribute to poor outcomes. Our aims were to determine the influence of obesity on morbidity and mortality in adults with CHD undergoing surgical repair at a free standing children's hospital. A retrospective analysis of adult (≥18 years) CHD surgery cases from 2002 to 2008 was performed. Congenital heart lesions were defined as mild, moderate, or complex. Patients were categorized by body mass index (BMI): underweight (BMI obese (BMI ≥ 30 kg/m(2)). Demographics, incidence of mortality, or specific morbidities were statistically compared using Fisher's exact test and analyses of variance (anovas). In this population (n = 165), overweight (29%) and obese (22%) patients were prevalent. Hypertension (HTN) and pre-HTN were more prevalent in obese and overweight patients. Postoperative renal dysfunction was observed in obese patients with complex CHD (P = .04). Mortality was not different among groups. Obesity is becoming increasingly common among adults with CHD. Despite marginal evidence of postoperative renal complications in obese patients with CHD of severe complexity, the overall presence of obesity did not influence mortality or short term postoperative morbidities. © 2011 Copyright the Authors.

    This study sought to investigate the clinical outcome and the role of postoperative radiotherapy for patients with salivary duct carcinoma (SDC) who had undergone surgery and postoperative radiotherapy. We performed a retrospective analysis of 25 SDC patients treated between 1998 and 2011 with surgery and postoperative radiotherapy. The median prescribed dose was 60 Gy (range, 49.5-61.4 Gy). The clinical target volume (CTV) was defined as the tumor bed in four patients, the tumor bed and ipsilateral neck in 14 patients, and the tumor bed and bilateral neck in six patients. Local control (LC), disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method, and prognostic variables were analyzed with the log-rank test. The 5-year LC, DFS and OS were 67%, 45% and 47%, respectively. Disease recurrence was found in 12 patients: seven as local, four as regional and eight as distant failure. Perineural and lymphovascular invasion was a significant prognostic factor for LC (P=0.03). Local failure was common, and the presence of local recurrence significantly affected the OS (P<0.05). We conclude that surgery and postoperative radiotherapy is expected to decrease the risk of local failure and contribute to good prognoses for patients with SDC. It might be advisable to have the CTV include the cranial nerves involved and the corresponding parts of the skull base in cases of pathologically positive perineural invasion. (author)

    Full Text Available Background: Increased serum lactate during cardio-pulmonary bypass is associated with high mortality and cardiac complications up to 10-20 percent. The aim of this study was to evaluate the effect of serum lactate increase on postoperative outcomes after coronary artery bypass graft (CABG Surgery. Materials and Methods: This descriptive-analytical study was performed on cases (no=116 undergoing CABG at Beheshti hospital in Kashan between 2013-2014. Demographic data, variables related to surgery, serum lactate level and the time of tracheal extubation, length of stay in intensive care unit (ICU and hospital post-surgery left ventricular ejection fraction were collected. These data was compared in two groups: Normal serum lactate ( 2 m mol\\liter group. Results: The postoperative hyperlactatemia was observed in 62.1 % of patients. There were no significant differences between two groups in time of tracheal extubation, length of stay in ICU and hospital. There was a relationship between the mean postoperative serum lactate and blood sugar, bicarbonate, pH, length of cardiopulmonary bypass and the aortic cross clamping time. There was a significant relationship between the serum lactate increment and the left ventricular ejection fraction decrement. Conclusion: Hyperlactatemia is probably associated with such important factors as high blood sugar, longer duration of aortic cross clamp and cardio-pulmonary bypass time. So controlling such factors can reduce the rate of hyperlactatemia and help postoperative recovery.

    This retrospective study was designed to investigate prognostic factors for postoperative outcomes for cubital tunnel syndrome (CubTS) using multiple logistic regression analysis with a large number of patients. Eighty-three patients with CubTS who underwent surgeries were enrolled. The following potential prognostic factors for disease severity were selected according to previous reports: sex, age, type of surgery, disease duration, body mass index, cervical lesion, presence of diabetes mellitus, Workers' Compensation status, preoperative severity, and preoperative electrodiagnostic testing. Postoperative severity of disease was assessed 2 years after surgery by Messina's criteria which is an outcome measure specifically for CubTS. Bivariate analysis was performed to select candidate prognostic factors for multiple linear regression analyses. Multiple logistic regression analysis was conducted to identify the association between postoperative severity and selected prognostic factors. Both bivariate and multiple linear regression analysis revealed only preoperative severity as an independent risk factor for poor prognosis, while other factors did not show any significant association. Although conflicting results exist regarding prognosis of CubTS, this study supports evidence from previous studies and concludes early surgical intervention portends the most favorable prognosis.

    To evaluate the impact of glycemic control and nutritional status after total pancreatectomy (TP) on complications, tumor recurrence and overall survival. Retrospective records of 52 patients with pancreatic tumors who underwent TP were collected from 2007 to 2015. A series of clinical parameters collected before and after surgery, and during the follow-up were evaluated. The associations of glycemic control and nutritional status with complications, tumor recurrence and long-term survival were determined. Risk factors for postoperative glycemic control and nutritional status were identified. High early postoperative fasting blood glucose (FBG) levels (OR = 4.074, 95%CI: 1.188-13.965, P = 0.025) and low early postoperative prealbumin levels (OR = 3.816, 95%CI: 1.110-13.122, P = 0.034) were significantly associated with complications after TP. Postoperative HbA1c levels over 7% (HR = 2.655, 95%CI: 1.299-5.425, P = 0.007) were identified as one of the independent risk factors for tumor recurrence. Patients with postoperative HbA1c levels over 7% had much poorer overall survival than those with HbA1c levels less than 7% (9.3 mo vs 27.6 mo, HR = 3.212, 95%CI: 1.147-8.999, P = 0.026). Patients with long-term diabetes mellitus (HR = 15.019, 95%CI: 1.278-176.211, P = 0.031) and alcohol history (B = 1.985, SE = 0.860, P = 0.025) tended to have poor glycemic control and lower body mass index levels after TP, respectively. At least 3 mo are required after TP to adapt to diabetes and recover nutritional status. Glycemic control appears to have more influence over nutritional status on long-term outcomes after TP. Improvement in glycemic control and nutritional status after TP is important to prevent early complications and tumor recurrence, and improve survival.

    Sciatica is often caused by a herniated lumbar intervertebral disc. When conservative treatment fails, a lumbar discectomy can be performed. Surgical treatment via lumbar discectomy is not always successful and may depend on a variety of preoperative factors. It remains unclear which, if any, preoperative factors can predict postsurgical clinical outcomes. This review aimed to determine preoperative predictors that are associated with postsurgical clinical outcomes in patients undergoing lumbar discectomy. This is a systematic review. This systematic review of the scientific literature followed the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. MEDLINE and PubMed were systematically searched through June 2014. Results were screened for relevance independently, and full-text studies were assessed for eligibility. Reporting quality was assessed using a modified Newcastle-Ottawa Scale. Quality of evidence was assessed using a modified version of Sackett's Criteria of Evidence Support. No financial support was provided for this study. No potential conflict of interest-associated biases were present from any of the authors. The search strategy yielded 1,147 studies, of which a total of 40 high-quality studies were included. There were 17 positive predictors, 20 negative predictors, 43 non-significant predictors, and 15 conflicting predictors determined. Preoperative predictors associated with positive postoperative outcomes included more severe leg pain, better mental health status, shorter duration of symptoms, and younger age. Preoperative predictors associated with negative postoperative outcomes included intact annulus fibrosus, longer duration of sick leave, worker's compensation, and greater severity of baseline symptoms. Several preoperative factors including motor deficit, side and level of herniation, presence of type 1 Modic changes and degeneration, age, and gender had non-significant associations with postoperative clinical

    Full Text Available Background. Cutting the sternothyroid (ST muscle is a useful technique to expose the superior pole of thyroid gland during thyroidectomy. In this study, we evaluated the impact of partial cutting of the ST muscle on postoperative vocal outcomes after total thyroidectomy. Methods. A retrospective review of 57 patients who underwent total thyroidectomy with central neck dissection for micropapillary thyroid carcinoma was conducted. Group A (n=26 included those without cutting the ST muscle, while group B (n=31 included patients whose muscle was partially cut at the superior pole. All patients underwent voice analysis before the operation and 2 weeks and 1 month after the surgery, and the outcomes were compared between the two groups. Results. There were no differences between the two groups regarding the outcomes at each time of voice analysis. Group A showed a decrease of maximum frequency 2 weeks after surgery but showed no difference after 1 month. Group B showed a mild decrease in maximum frequency 2 weeks after surgery, but the difference was not significant. Conclusion. Partial cutting of ST muscle during thyroidectomy is useful to expose the superior pole without significant negative impact on postoperative outcomes of vocal analysis.

    The contribution of intimal hyperplasia (IH) to arteriovenous fistula (AVF) failure is uncertain. This observational study assessed the relationship between pre-existing, postoperative, and change in IH over time and AVF outcomes. Prospective cohort study with longitudinal assessment of IH at the time of AVF creation (pre-existing) and transposition (postoperative). Patients were followed up for up to 3.3 years. 96 patients from a single center who underwent AVF surgery initially planned as a 2-stage procedure. Veins and AVF samples were collected from 66 and 86 patients, respectively. Matched-pair tissues were available from 56 of these patients. Pre-existing, postoperative, and change in IH over time. Anatomic maturation failure was defined as an AVF that never reached a diameter > 6mm. Primary unassisted patency was defined as the time elapsed from the second-stage surgery to the first intervention. Maximal intimal thickness in veins and AVFs and change in intimal thickness over time. Pre-existing IH (>0.05mm) was present in 98% of patients. In this group, the median intimal thickness increased 4.40-fold (IQR, 2.17- to 4.94-fold) between AVF creation and transposition. However, this change was not associated with pre-existing thickness (r(2)=0.002; P=0.7). Ten of 96 (10%) AVFs never achieved maturation, whereas 70% of vascular accesses remained patent at the end of the observational period. Postoperative IH was not associated with anatomic maturation failure using univariate logistic regression. Pre-existing, postoperative, and change in IH over time had no effects on primary unassisted patency. The small number of patients from whom longitudinal tissue samples were available and low incidence of anatomic maturation failure, which decreased the statistical power to find associations between end points and IH. Pre-existing, postoperative, and change in IH over time were not associated with 2-stage AVF outcomes. Copyright © 2016 National Kidney Foundation, Inc

    To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

    To compare postoperative outcomes of individuals with and without cognitive impairment enrolled in the Perioperative Optimization of Senior Health (POSH) program at Duke University, a comanagement model involving surgery, anesthesia, and geriatrics. Retrospective analysis of individuals enrolled in a quality improvement program. Tertiary academic center. Older adults undergoing surgery and referred to POSH (N = 157). Cognitive impairment was defined as a score less than 25 out of 30 (adjusted for education) on the St. Louis University Mental Status (SLUMS) Examination. Median length of stay (LOS), mean number of postoperative complications, rates of postoperative delirium (POD, %), 30-day readmissions (%), and discharge to home (%) were compared using bivariate analysis. Seventy percent of participants met criteria for cognitive impairment (mean SLUMS score 20.3 for those with cognitive impairment and 27.7 for those without). Participants with and without cognitive impairment did not significantly differ in demographic characteristics, number of medications (including anticholinergics and benzodiazepines), or burden of comorbidities. Participants with and without cognitive impairment had similar LOS (P = .99), cumulative number of complications (P = .70), and 30-day readmission (P = .20). POD was more common in those with cognitive impairment (31% vs 24%), but the difference was not significant (P = .34). Participants without cognitive impairment had higher rates of discharge to home (80.4% vs 65.1%, P = .05). Older adults with and without cognitive impairment referred to the POSH program fared similarly on most postoperative outcomes. Individuals with cognitive impairment may benefit from perioperative geriatric comanagement. Questions remain regarding the validity of available measures of cognition in the preoperative period. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

    NICE guidelines state that patients with psychological contra-indications should not be considered for bariatric surgery, including Laparoscopic Adjustable Gastric Banding (LAGB) surgery as treatment of morbid obesity, although no consistent correlation between psychiatric illness and long-term outcome in LAGB has been established. This is to our knowledge the first study to evaluate long-term outcomes in LAGB for a full range of DSM-IV defined psychiatric and eating disorders, and forms part of a research portfolio developed by the authors aimed at defining psychological predictors of bariatric surgery in the short-, medium- and long-term. Case notes of 37 subjects operated on between April 1997 and June 2000, who had undergone structured clinical interview during pre-surgical assessment to yield diagnoses of mental and eating disorders according to DSM-IV criteria were analyzed according to a set of operationally defined criteria. Statistical analysis was carried out to compare those with a poor outcome and those considered to have a good outcome in terms of psychiatric profile. In this group of mainly female, Caucasian subjects, ranging in age from 27 to 60 years, one-third were diagnosed with a mental disorder according to DSM-IV criteria. The development of postoperative DSM-IV defined binge eating disorder (BED) or depression strongly predicted poor surgical outcome, but pre-surgical psychiatric factors alone did not. Although pre-surgical psychiatric assessment alone cannot predict outcome, an absence of preoperative psychiatric illness should not reassure surgeons who should be mindful of postoperative psychiatric sequelae, particularly BED. The importance of providing an integrated biopsychosocial model of care in bariatric teams is highlighted.

    To assess the retear rate, retear size and location, the clinical impact of a retear, and preoperative patient factors related to postoperative outcome after arthroscopic suture bridge rotator cuff repair. Fifty six patients with an isolated, full-thickness supraspinatus tendon tear who underwent arthroscopic suture bridge rotator cuff repair were retrospectively identified. Patients were evaluated and rotator cuff integrity was assessed using ultrasonography. Visual analog score (VAS), the American Shoulder and Elbow Surgeon (ASES) score, shoulder range of motion and strength were used for clinical evaluation. Retears were assessed for size and location on ultrasonography. Forty two patients (75%) aged a mean 59.7 ± 8.6 years (range 41-79 years) were available for follow-up at a mean 13.5 months. Postoperative evaluation indicated significant improvements in ASES score (49.76 ± 18.2 to 86.57 ± 13.4, P rotation ROM (44.13° ± 12.0 to 52.09° ± 12.0, P = 0.003). The retear rate was 14.28% (6/42). Patients with retears were not older (P = 0.526) but had a larger preoperative tear size (3.25 cm ± 0.5 vs. 2.05 cm ± 0.48, P rotation ROM (P = 0.002), and internal rotation strength (P = 0.004). Arthroscopic suture bridge repair provides good clinical results with a low retear rate. The duration of preoperative symptoms was associated with postoperative outcome, indicating that delaying surgery may result in inferior outcomes. IV, Case Series.

    Full Text Available Context : Pre- and postoperative distress in breast cancer patients can cause complications and delay recovery from surgery. Objective : The aim of our study was to evaluate the effects of yoga intervention on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery. Methods : Ninety-eight recently diagnosed stage II and III breast cancer patients were recruited in a randomized controlled trial comparing the effects of a yoga program with supportive therapy and exercise rehabilitation on postoperative outcomes and wound healing following surgery. Subjects were assessed at the baseline prior to surgery and four weeks later. Sociodemographic, clinical and investigative notes were ascertained in the beginning of the study. Blood samples were collected for estimation of plasma cytokines-soluble Interleukin (IL-2 receptor (IL-2R, tumor necrosis factor (TNF-alpha and interferon (IFN-gamma. Postoperative outcomes such as the duration of hospital stay and drain retention, time of suture removal and postoperative complications were ascertained. We used independent samples t test and nonparametric Mann Whitney U tests to compare groups for postoperative outcomes and plasma cytokines.

    Pre- and postoperative distress in breast cancer patients can cause complications and delay recovery from surgery. The aim of our study was to evaluate the effects of yoga intervention on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery. Ninety-eight recently diagnosed stage II and III breast cancer patients were recruited in a randomized controlled trial comparing the effects of a yoga program with supportive therapy and exercise rehabilitation on postoperative outcomes and wound healing following surgery. Subjects were assessed at the baseline prior to surgery and four weeks later. Sociodemographic, clinical and investigative notes were ascertained in the beginning of the study. Blood samples were collected for estimation of plasma cytokines-soluble Interleukin (IL)-2 receptor (IL-2R), tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma. Postoperative outcomes such as the duration of hospital stay and drain retention, time of suture removal and postoperative complications were ascertained. We used independent samples t test and nonparametric Mann Whitney U tests to compare groups for postoperative outcomes and plasma cytokines. Regression analysis was done to determine predictors for postoperative outcomes. Sixty-nine patients contributed data to the current analysis (yoga: n = 33, control: n = 36). The results suggest a significant decrease in the duration of hospital stay (P = 0.003), days of drain retention (P = 0.001) and days for suture removal (P = 0.03) in the yoga group as compared to the controls. There was also a significant decrease in plasma TNF alpha levels following surgery in the yoga group (P < 0.001), as compared to the controls. Regression analysis on postoperative outcomes showed that the yoga intervention affected the duration of drain retention and hospital stay as well as TNF alpha levels. The results suggest possible benefits of yoga in reducing postoperative complications in

    The aim of this study is to assess the long-term clinical and radiological outcomes between minimally invasive (MIS) and conventional transforaminal lumbar interbody fusion (TLIF) in treating one-segment lumbar disc herniation (LDH). One-hundred and six patients treated by MIS-TLIF (50 cases) or conventional TLIF (56 cases) were included. Perioperative results were evaluated. Clinical outcomes were compared preoperatively and postoperatively. Radiologic parameters were based on a comparison of preoperative and three-year postoperative lumbar lordosis, segmental lordosis, sacral slope, the cross-sectional area of the paraspinal muscle and fusion rates. MIS TILF had significantly less blood, shorter operation time, mean return to work time and lower intramuscular pressure compared with the conventional group during the operation. VAS scores for lower back pain and ODI in MIS-TLIF were significantly decreased. The mean cross-sectional area of the paraspinal muscle was significantly decreased after surgery in the conventional TLIF group and no significant intragroup differences were established in the MIS-TLIF group. No significant differences were found in fusion rate, lumbar lordosis, segmental lordosis and sacral slope. Both MIS and conventional TLIF were beneficial for patients with LDH. However, MIS-TLIF manifests a great improvement in perioperative outcomes, low back pain, disability and preventing paraspinal muscle atrophy during the follow-up period observation.

    Frailty is defined as a state of decreased reserve and susceptibility to stressors. The relationship between frailty and postoperative outcomes after degenerative spine surgery has not been studied. This study aimed to (1) determine prevalence of frailty in the degenerative spine population; (2) describe patient characteristics associated with frailty; and (3) determine the association between frailty and postoperative complications, mortality, length of stay, and discharge disposition. This is a retrospective analysis on a prospectively collected cohort from the National Surgical Quality Improvement Program (NSQIP). A total of 53,080 patients who underwent degenerative spine surgery between 2006 and 2012 were included in the study. A modified frailty index (mFI) with 11 variables derived from the NSQIP dataset was used to determine prevalence of frailty and its correlation with a composite outcome of perioperative complications as well as hospital length of stay, mortality, and discharge disposition. After calculating the mFI for each patient, the prevalence and predictors of frailty were determined for our cohort. The association of frailty with postoperative outcomes was determined after adjusting for known and suspected confounders using multivariate logistic regression. Frailty was present in 2,041 patients within the total population (4%) and in 8% of patients older than 65 years. Frailty severity increased with increasing age, male sex, African American race, higher body mass index, recent weight loss, paraplegia or quadriplegia, American Society of Anesthesiologists (ASA) score, and preadmission residence in a care facility. Frailty severity was an independent predictor of major complication (OR 1.15 for every 0.10 increase in mFI, 95%CI 1.09-1.21, pdegenerative spine surgery. Preoperative recognition of frailty may be useful for perioperative optimization, risk stratification, and patient counseling. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background Enthusiasm for laparoscopic surgical approaches to prostate cancer treatment has grown, despite limited evidence of improved outcomes compared with open radical prostatectomy. We compared laparoscopic (with or without robotic assistance) versus open radical prostatectomy in terms of postoperative outcomes and subsequent cancer-directed therapy. Materials and Methods Using a population-based cancer registry linked with Medicare claims, we identified men age 66 or older with localized prostate cancer who received a radical prostatectomy from 2003-2005. Outcome measures were general medical/surgical complications and mortality within 90 days following surgery; genitourinary/bowel complications within 365 days; receipt of radiation therapy, androgen deprivation therapy or both within 365 days; length of hospital stay. Results Of the 5,923 men,18% received a laparoscopic radical prostatectomy. Adjusting for patient and tumor characteristics, there were no differences in rates of general medical/surgical complications (OR 0.93; 95% CI: 0.77-1.14) or genitourinary/bowel complications (OR 0.96; 95% CI: 0.76-1.22) or in the use of postoperative radiation, androgen deprivation or both (OR 0.80; 95% CI: 0.60-1.08). Laparoscopic prostatectomy was associated with a 35% shorter hospital stay (p<0.0001) and a lower rate of bladder neck/urethral obstruction (OR 0.74; 95% CI 0.58-0.94). In laparoscopic patients, surgeon volume was inversely associated with length of hospital stay and the odds of any genitourinary/bowel complication. Conclusions Laparoscopic and open radical prostatectomy have similar rates of postoperative morbidity and use of additional treatment. Men considering prostate cancer surgery should understand the expected benefits and risks of each technique to facilitate decision-making and to set realistic expectations. PMID:20188381

    To compare the intraoperative performance and postoperative outcomes of 3 phacoemulsification machines that use different modes. Kensington Eye Institute, Toronto, Ontario, Canada. Comparative case series. This chart and video review comprised consecutive eligible patients who had phacoemulsification by the same surgeon using a Whitestar Signature Ellips-FX (transversal), Infiniti-Ozil-IP (torsional), or Stellaris (longitudinal) machine. The review included 98 patients. Baseline characteristics in the groups were similar; the mean nuclear sclerosis grade was 2.0 ± 0.8. There were no significant intraoperative complications. The torsional machine averaged less phacoemulsification needle time (83 ± 33 seconds) than the transversal (99 ± 40 seconds; P=.21) or longitudinal (110 ± 45 seconds; P=.02) machines; the difference was accentuated in cases with high-grade nuclear sclerosis. The torsional machine had less chatter and better followability than the transversal or longitudinal machines (P<.001). The torsional and longitudinal machines had better anterior chamber stability than the transversal machine (P<.001). Postoperatively, the torsional machine yielded less central corneal edema than the transversal (P<.001) and longitudinal (P=.04) machines, corresponding to a smaller increase in mean corneal thickness (torsional 5%, transversal 10%, longitudinal 12%; P=.04). Also, the torsional machine had better 1-day postoperative visual acuities (P<.001). All 3 phacoemulsification machines were effective with no significant intraoperative complications. The torsional machine outperformed the transversal and longitudinal machines, with a lower mean needle time, less chatter, and improved followability. This corresponded to less corneal edema 1 day postoperatively and better visual acuity. Copyright © 2011 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

    To compare the accuracy of R2CHADS2, CHADS2, and CHA2DS2-VASc scores vs the Society of Thoracic Surgeons (STS) score as predictors of morbidity and mortality after cardiovascular surgery. All patients who underwent cardiothoracic surgery at our institution from January 2008 to July 2013 were analyzed. Only those patients who fulfilled the criteria for STS score calculation were included. The R2CHADS2 score was computed as follows: 2 points for GFR < 60 mL/min/1.73 m(2) (R2), prior stroke or TIA (S2); 1 point for history of congestive heart failure (C), hypertension (H), age ≥75 years (A), or diabetes (D). Area under the curve (AUC) analysis was used to estimate the accuracy of the different scores. The end point variables included operative mortality, permanent stroke, and renal failure as defined by the STS database system. Of the 3,492 patients screened, 2,263 met the inclusion criteria. These included 1,160 (51%) isolated valve surgery, 859 (38%) coronary artery bypass graft surgery, and 245 (11%) combined procedures. There were 147 postoperative events: 75 (3%) patients had postoperative renal failure, 48 (2%) had operative mortality, and 24 (1%) had permanent stroke. AUC analysis revealed that STS, R2CHADS2, CHADS2, and CHA2DS2-VASc reliably estimated all postoperative outcomes. STS and R2CHADS2 scores had the best accuracy overall, with no significant difference in AUC values between them. The R2CHADS2 score estimates postoperative events with acceptable accuracy and if further validated may be used as a simple preoperative risk tool calculator. Copyright © 2016 Elsevier Inc.

    Despite modern advancements in transosseous fixation and operative technique, hallux valgus (i.e., bunion) surgery is still associated with a higher than usual amount of patient dissatisfaction and is generally recognized as a complex and nuanced procedure requiring precise osseous and capsulotendon balancing. It stands to reason then that familiarity and skill level of trainee surgeons might impact surgical outcomes in this surgery. The aim of this study was to determine whether podiatry resident experience level influences midterm outcomes in hallux valgus surgery (HVS). Consecutive adults who underwent isolated HVS via distal metatarsal osteotomy at a single US metropolitan teaching hospital from January 2004 to January 2009 were contacted and asked to complete a validated outcome measure of foot health (Manchester-Oxford Foot Questionnaire) regarding their operated foot. Resident experience level was quantified using the surgical logs for the primary resident of record at the time of each case. Associations were assessed using linear and logistic regression analyses. A total of 102 adult patients (n = 102 feet) agreed to participate with a mean age of 46.8 years (standard deviation 13.1, range 18-71) and average length of follow-up 6.2 y (standard deviation 1.4, range 3.6-8.6). Level of trainee experience was not associated with postoperative outcomes in either the univariate (odds ratio 0.99 [95% confidence interval, 0.98-1.01], P = 0.827) or multivariate analyses (odds ratio 1.00 [95% confidence interval, 0.97-1.02], P = 0.907). We conclude that podiatry resident level of experience in HVS does not contribute appreciably to postoperative clinical outcomes. Copyright © 2014 Elsevier Inc. All rights reserved.

    Health-related quality of life (HRQL) data are becoming an important supplement to information pertaining to treatment outcome for cancer patients. The purpose of this study was to evaluate the HRQL outcome for oral cancer survivors after surgery plus postoperative radiotherapy (RT) and to investigate the variables associated with their HRQL. Sixty-six oral cancer patients with cancer-free survival after surgery plus postoperative RT of >2 years were enrolled. The Short Form-36 (SF-36) questionnaire in the Taiwan Chinese version was self-reported by all participants at the clinics. The linear regression model was used to analyze the socio-demographic and medical-related variables correlated with the physical component summary (PCS) and mental component summary (MCS) in SF-36. The mean scores of the eight functional domains in the SF-36 were markedly lower for oral cancer survivors compared with the Taiwanese and US norms. Those with older age, lower annual family income, more advanced cancer stage and flap reconstruction had significantly worse PCS, and those with lower annual family income, unemployment and more advanced cancer stage reported significantly worse MCS. This model accounts for 63% of variance in PCS, and 51% in MCS. These results provided patient-reported evidence that oral cancer survivors lived with a worse HRQL compared with the general Taiwanese population. Socio-economic factors and cancer stage were important factors correlated with their HRQL. (authors)

    To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

    To assess the incidence and the prognostic value of acute postoperative seizures (APOS) in patients surgically treated for drug-resistant temporal lobe epilepsy due to hippocampal sclerosis (TLE-HS). We studied 139 consecutive patients with TLE-HS who underwent epilepsy surgery and were followed up for at least 5 years (mean duration of follow-up 9.1 years, range 5-15). Medical charts were reviewed to identify APOS, defined as ictal events with the exception of auras occurring within the first 7 days after surgery. Seizure outcome was determined at annual intervals. Patients who were in Engel Class Ia at the last contact were classified as having a favorable outcome. Seizure outcome was favorable in 99 patients (71%). Six patients (4%) experienced APOS and in all cases their clinical manifestations were similar to the habitual preoperative seizures. All patients with APOS had unfavorable long-term outcome, as compared with 35 (26%) of 133 in whom APOS did not occur (pseizure outcome. Given some study limitations, our findings should be regarded as preliminary and need confirmation from future larger, prospective, multicenter studies. Copyright © 2014 British Epilepsy Association.

    Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery, especially during the first 3

    Full Text Available Abstract Objective: To investigate the impact of gender difference in early postoperative outcomes in elderly patients (aged 70 or older undergoing coronary artery bypass grafting surgery. Methods: Between October 2009 and December 2013, a total of 223 elderly patients (aged 70 or older undergoing isolated primary coronary artery bypass grafting surgery were included in this retrospective observational cohort study. Patients were divided into two groups according to their gender. The patients' medical records were collected, their baseline preoperative characteristics, operative data, and postoperative outcomes were retrospectively reviewed, and the effect of gender difference in the early postoperative outcomes was analyzed. Results: Group 1 (female patients and Group 2 (male patients consisted of 71 and 152 patients, respectively. Mean age of patients was 74.4±3.6 years (range: 70-84 years. The level of EuroSCORE I, the incidence of hypertension and hyperlipidemia were significantly higher in Group 1, while the rate of smoking was significantly higher in Group 2. Mean postoperative intubation time, length of intensive care unit and hospital stay were longer in female patients than in male patients, but these differences were not statistically significant. No statistically significant difference between two groups in terms of the transfusion of blood products was observed. The rates of in-hospital mortality and major postoperative complications were statistically similar between the two groups. Conclusion: In conclusion, the female gender was not associated with worse early postoperative outcomes in elderly patients undergoing coronary artery bypass grafting surgery.

    Current surgical indications for Graves' disease include intractability to medical and/or radioablative therapy, compressive symptoms, and worsening ophthalmopathy. Total thyroidectomy for Graves' disease may be technically challenging and lead to untoward perioperative outcomes. This study examines outcomes in patients with Graves' disease who underwent total thyroidectomy and assesses its safety for this patient population. A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample database from 2006 to 2011. Total thyroidectomy performed in patients with Graves' disease, benign multinodular goiter (MNG), and thyroid cancer was identified. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-square, one-way analysis of variance, and risk-adjusted multivariable logistic regression were performed. Of 215,068 patients who underwent total thyroidectomy during the study period, 11,205 (5.2%) had Graves' disease, 110,124 (51.2%) MNG, and 93,739 (43.6%) thyroid malignancy.

    To investigate presurgical diagnostic modalities, clinical and seizure outcome as well as predictive factors after resective epilepsy surgery in 3 Tesla MRI-negative focal epilepsies. This retrospective study comprises 26 patients (11 males/15 females, mean age 34±12years, range 13-50 years) with 3 Tesla MRI-negative focal epilepsies who underwent resective epilepsy surgery. Non-invasive and invasive presurgical diagnostic modalities, type and localization of resection, clinical and epileptological outcome with a minimum follow-up of 1year (range 1-11 years, mean 2.5±2.3years) after surgery as well as outcome predictors were evaluated. All patients underwent invasive video-EEG monitoring after implantation of intracerebral depth and/or subdural electrodes. Ten patients received temporal and 16 extratemporal or multilobar (n=4) resections. There was no perioperative death or permanent morbidity. Overall, 12 of 26 patients (46%) were completely seizure-free (Engel IA) and 65% had a favorable outcome (Engel I-II). In particular, seizure-free ratio was 40% in the temporal and 50% in the extratemporal group. In the temporal group, long duration of epilepsy correlated with poor seizure outcome, whereas congruent unilateral FDG-PET hypometabolism correlated with a favorable outcome. In almost two thirds of temporal and extratemporal epilepsies defined as "non-lesional" by 3 Tesla MRI criteria, a favorable postoperative seizure outcome (Engel I-II) can be achieved with accurate multimodal presurgical evaluation including intracranial EEG recordings. In the temporal group, most favorable results were obtained when FDG-PET displayed congruent unilateral hypometabolism. Copyright © 2017 Elsevier B.V. All rights reserved.

    We compared outcomes and xerostomia grade after postoperative intensity-modulated radiation therapy (IMRT) and conventional radiotherapy (RT) in patients with oral and oropharyngeal carcinoma. Eighty-eight patients with oral cavity (n = 77) and oropharyngeal (n = 11) carcinoma underwent postoperative IMRT (n = 44) or conventional RT (n = 44). Outcomes, failure patterns, volume, doses, salivary gland V30, and xerostomia grade were evaluated. The median follow-up was 53 months (range, 48-58 months). The median interval from surgery to RT was 4 weeks (range, 3-6 weeks). Twenty-one patients (7 and 14 for the IMRT and conventional RT groups, respectively) experienced local-regional failure. For the IMRT group, all 7 local-regional failures occurred in the high-dose target volumes. For the conventional RT group, there were 12 in-field failures, 1 at the margin, and 1 out-of-field. Nine patients experienced distant failure (5 and 4 for the IMRT and conventional RT groups, respectively). The 4-year local-regional control, disease-free survival (DFS), overall survival (OS), and distant-metastasis rates for the IMRT and conventional RT groups were 84.1% versus 68.2% (p = .055), 68.2% versus 52.3% (p = .091), 70.5% versus 56.8% (p = .124), and 11.4% versus 9.1% (p = .927), respectively. Xerostomia grade after RT was lower for IMRT compared to conventional RT (p xerostomia grade when compared to conventional RT. The predominant failure pattern was local. No differences were found in survival outcomes between both groups. There was a marginal difference in local-regional control. © 2014 Wiley Periodicals, Inc.

    High-frequency stimulation of the subthalamic nucleus (STN-HFS) is highly effective in treating motor symptoms in Parkinson's disease (PD) and medication side effects as well as in improving quality of life. Despite preoperative screening for patients as eligible candidates for this treatment, electrode position may furthermore influence treatment quality. Here, we investigated the relationship between the anatomical site of stimulation within the MRI-defined STN and the outcome of PD patients after STN-HFS. In 30 PD patients with bilateral STN stimulation, we retrospectively defined the boundaries of the STN within the axial target plane of the stereotactic T2-weighted MRI and determined the position of the active electrode contact in relation to the border of the STN. The position of the active contact within the STN was the only variable to predict the outcome of STN stimulation. In contrast, covariates such as age, disease duration, symptom severity, and response to levodopa had no effect. The lateral position of the stimulation contact within the STN led to significantly better clinical improvement, lower stimulation parameters, and less need for postoperative dopaminergic medication. The outcome of patients with stimulation contacts within the medial region of the STN was significantly worse. Precise targeting of the lateral region of the STN is essential for achieving sufficient stimulation efficacy. Preoperative T2-weighted MRI might be a useful component of the targeting procedure to improve the outcome of PD patients. Copyright © 2012 Movement Disorder Society.

    Prior studies have shown that patient-reported allergies can be prognostic of poorer postoperative outcomes. To investigate the correlation between self-reported allergies and outcomes after cervical or lumbar spine surgery. Retrospective cohort study at a single tertiary-care institution. All patients undergoing cervical or lumbar spine surgery from 2009-2014. The primary outcome measure was change in the EuroQol-5 Dimensions (EQ-5D) following surgery. Secondary outcomes included change in the Pain Disability Questionnaire (PDQ) and Patient Health Questionnaire-9 (PHQ-9), achieving the minimal clinically important difference (MCID) in these measures, as well as cost of admission. Prior to and following surgery, EQ-5D, PDQ, and PHQ-9 were recorded for patients with available data. Paired student's t-tests were used to compare change in these measures following surgery. Multivariable linear and logistic regression were used to assess the relationship between the log transformation of the total number of allergies and outcomes. 592 cervical patients and 4,465 lumbar patients were included. The median number of reported allergies was two. The EQ-5D index increased from 0.539 to 0.703 for cervical patients and from 0.530 to 0.676 for lumbar patients (pallergies predicted significantly higher odds of achieving the PDQ MCID (OR = 2.09, 95% CI 1.05-4.15, p=0.02 for cervical patients; OR = 1.30, 95% CI 1.03-1.68, p=0.03 for lumbar patients). However, this relationship was not durable for patients with follow-up exceeding 1 year. The log transformation of number of allergies for lumbar patients predicted significantly increased cost of admission (β=$3,597, pallergies correlate with subjective improvement in pain and disability following spine surgery and may serve as a marker of postoperative outcomes. The relationship between allergies and PDQ improvement may be secondary to the short-term expectation-actuality discrepancy, as this relationship was not durable beyond 1

    Background and purpose: although gemistocytic astrocytomas are considered slow-growing tumors, they often behave aggressively and carry the least favorable prognosis among low-grade astrocytomas. The aim of this study is to evaluate the outcomes and prognostic factors of patients with incompletely excised gemistocytic astrocytomas irradiated postoperatively. Patients and methods: records of 48 patients with incompletely excised gemistocytic astrocytoma, irradiated between 1976 and 1998 at the department of radiation oncology, Maria Sklodowska-curie Memorial Cancer Center, Cracow, Poland, were reviewed. The total dose ranged from 50 to 60 Gy (mean: 59.35, median: 60 Gy) delivered in daily fractions of 2 Gy, 5 days a week. The treatment volume covered the residual tumor with a margin of 1-2 cm. Results: toxicity was acceptable. The overall actuarial survival rates at 5 and 10 years were 30% and 17%, respectively. Age and gender had an influence on overall survival by univariate and multivariate analysis (p < 0.05). Patients ≤ 35 years of age and female patients carried the best prognosis. Conclusion: in most patients with gemistocytic astrocytoma, combined surgery and postoperative radiotherapy result in only short-term survival. Older age is the most important unfavorable prognostic factor in patients with gemistocytic astrocytoma. (orig.)

    Patient selection remains paramount when developing and adopting quality-based assessment and reimbursement models, and enhanced recovery protocols. Gender is a patient characteristic known before surgery which can inform risk stratification. Our aim was to evaluate the effect of gender on intraoperative blood transfusions, operative time, length of hospital stay, estimated blood loss (EBL) as well as postoperative surgical site infections (SSIs), and mortality. Patients undergoing elective pancreatectomy from 2005 to 2013 were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and Northwestern institutional databases. Multivariable analyses were conducted to identify the association between gender and these outcomes. Analyses demonstrated that male gender was independently associated with blood transfusion (OR 1.23), operative time >6 hr (OR 1.76), length of stay greater than 11 days (OR 1.17), and all-type SSIs (OR 1.17), especially superficial SSIs (OR 1.15) and organ space SSIs (OR 1.18). Analysis of the institutional cohort found that male gender was independently associated with increased odds of EBL > 1 L for Whipple procedures (OR 2.85). Male gender is a significant predictor of increased operative time, length of stay, transfusions, EBL > 1L, as well as postoperative organ space surgical site infections in these patients. J. Surg.

    This single institutional study is aimed to observe the outcome of patients who received postoperative radiotherapy after radical prostatectomy. A total of 59 men with histologically identified prostate adenocarcinoma who had received postoperative radiation after radical prostatectomy from August 2005 to July 2011 in Seoul St. Mary's Hospital of the Catholic University of Korea, was included. They received 45-50 Gy to the pelvis and boost on the prostate bed was given up to total dose of 63-72 Gy (median, 64.8 Gy) in conventional fractionation. The proportion of patients given hormonal therapy and the pattern in which it was given were analyzed. Primary endpoint was biochemical relapse-free survival (bRFS) after radiotherapy completion. Secondary endpoint was overall survival (OS). Biochemical relapse was defined as a prostate-specific antigen level above 0.2 ng/mL. After median follow-up of 53 months (range, 0 to 104 months), the 5-year bRFS of all patients was estimated 80.4%. The 5-year OS was estimated 96.6%. Patients who were given androgen deprivation therapy had a 5-year bRFS of 95.1% while the ones who were not given any had that of 40.0% (p < 0.01). However, the statistical significance in survival difference did not persist in multivariate analysis. The 3-year actuarial grade 3 chronic toxicity was 1.7% and no grade 3 acute toxicity was observed. The biochemical and toxicity outcome of post-radical prostatectomy radiotherapy in our institution is favorable and comparable to those of other studies.

    Background The functional lumen imaging probe (FLIP) is a novel diagnostic tool that can be used to measure esophagogastric junction (EGJ) distensibility. In this study we performed intraoperative FLIP measurements during laparoscopic Heller myotomy (LHM) and peroral esophageal myotomy (POEM) for treatment of achalasia and evaluated the relationship between EGJ distensibility and postoperative symptoms. Methods Distensibility index (DI) (defined as the minimum cross-sectional area at the EGJ divided by distensive pressure) was measured with FLIP at two time points during LHM and POEM: 1) at baseline after induction of anesthesia, and 2) after operation completion. Results Measurements were performed in 20 patients undergoing LHM and 36 undergoing POEM. Both operations resulted in an increase in DI, although this increase was larger with POEM (7±3.1 vs. 5.1±3.4mm2/mmHg, p3mm2/mmHg. When all patients were divided into thirds based on final DI, none in the lowest DI group (7), as compared with 20% in the middle third (6–9mm2/mmHg) and 36% in the highest third (>9mm2/mmHg). Patients within an “ideal” final DI range (4.5–8.5 mm2/mmHg) had optimal symptomatic outcomes (i.e. Eckardt≤1 and GerdQ≤7) in 88% of cases, compared with 47% in those with a final DI above or below that range (p<.05). Conclusions Intraoperative EGJ distensibility measurements with FLIP were predictive of postoperative symptomatic outcomes. These results provide initial evidence that FLIP has the potential to act as a useful calibration tool during operations for achalasia. PMID:25055891

    This is the first systematic review to synthesize the evidence concerning early post-operative variables predictive of later weight and psychosocial outcomes in bariatric surgery. Eight electronic databases for empirical studies were searched (1954 to 2016). Most of the 39 included studies reported solely on weight outcomes; eating and psychosocial outcomes were less common. A better early weight loss trajectory was the most consistent predictor of more successful medium-term weight outcome (≤24 months); however, its relationship to longer term weight loss maintenance is less certain. Early eating adaptation may be associated with later weight loss, but further research is needed. Evidence is lacking for associations between early adherence or early psychosocial variables and later outcome. In particular, the relationship between early post-operative depression and later weight remains unclear. Little research has considered early prediction of later eating or psychosocial outcomes. Consideration of mediating or moderating relationships is lacking. The body of evidence is limited, and synthesis is hampered by heterogeneity in the type and time at which predictors and outcomes are measured and quality of statistical reporting. Further research on prospective prediction of bariatric surgery outcome is needed to guide early post-operative intervention for those at greatest risk of poor outcomes. © 2017 World Obesity Federation.

    The incidence of surgical site infections (SSI) after adolescent idiopathic scoliosis (AIS) surgery ranges from 0.5% to 7%. There is currently a regain of interest in hybrid constructs, combining lumbar pedicle screws and thoracic sublaminar bands, but some authors have raised concerns about the risk of SSI and the difficulty of bacterial eradication. The goal of this study was therefore to assess the outcomes of SSI after AIS surgery using sublaminar bands. A total of 524 consecutive patients operated for AIS using sublaminar bands between June 2006 and June 2014 were included. SSI cases were identified and analyzed retrospectively. Radiologic and functional outcomes were evaluated at follow-up using EOS imaging and SRS 30 scores, and compared with a control group. The overall SSI rate was 5.3%, with a majority of monomicrobial (86%) infections occurring in the first 6 weeks postoperative (93%). The most frequent pathogens were skin germs (Staphylococcus aureus and Propionibacterium acnes) with a community profile. Patients were treated successfully with surgical debridement without implants removal, associated with 6 weeks of antibiotherapy. However, 25% of patients required >1 surgical debridement. Instrumentation removal was decided in the 2 cases with late SSI, and performed uneventfully. Radiologic and functional outcomes at follow-up were not affected by the occurrence of SSI. Sublaminar bands are not associated with a higher risk of infection. However, the SSI rate in the current study stands in the upper range of the literature, and other preventive strategies should be considered. In case of early infection, bands removal is not necessary to obtain pathogen eradication, but the sublaminar implants can be pulled out safely in case of late SSI. The occurrence of SSI does not alter the outcomes at follow-up. Level III.

    The aim of this study is to describe and relate nutritional and inflammatory status and prognostic indexes with postoperative complications and clinical outcome of patients with gastrointestinal malignancies. Twenty-nine patients were evaluated; nutritional assessment was carried out by subjective and objective parameters; albumin, pre-albumin, C-reactive protein (CRP), and alpha-1-acid glycoprotein (AGP) were determined. To assess prognosis, the Glasgow scale, the Prognostic Inflammatory Nutritional Index (PINI), and CRP/albumin ratio were used; the clinical outcomes considered were hospital discharge and death. A high Subjective Global Assessment (SGA) score was associated with the occurrence of postoperative complications: 73% of the patients with postoperative complications had the highest SGA score, but only 6% of those without postoperative complications had the highest SGA score (P 1, and Glasgow score 2. There was a positive correlation between weight loss percentage with serum CRP levels (P = 0.002), CRP/albumin (P = 0.002), PINI (P = 0.002), and Glasgow score (P = 0.000). This study provides evidence that the assessment of the nutritional status and the use of prognostic indexes are good tools for predicting postoperative complications and clinical outcome in patients with gastrointestinal neoplasia.

    The aim of this analysis was to investigate the impact of tumour-, treatment- and patient-related cofactors on local control and survival after postoperative adjuvant radiotherapy in patients with non-small cell lung cancer (NSCLC), with special focus on waiting and overall treatment times. For 100 NSCLC patients who had received postoperative radiotherapy, overall, relapse-free and metastases-free survival was retrospectively analysed using Kaplan-Meier methods. The impact of tumour-, treatment- and patient-related cofactors on treatment outcome was evaluated in uni- and multivariate Cox regression analysis. No statistically significant difference between the survival curves of the groups with a short versus a long time interval between surgery and radiotherapy could be shown in uni- or multivariate analysis. Multivariate analysis revealed a significant decrease in overall survival times for patients with prolonged overall radiotherapy treatment times exceeding 42 days (16 vs. 36 months) and for patients with radiation-induced pneumonitis (8 vs. 29 months). Radiation-induced pneumonitis and prolonged radiation treatment times significantly reduced overall survival after adjuvant radiotherapy in NSCLC patients. The negative impact of a longer radiotherapy treatment time could be shown for the first time in an adjuvant setting. The hypothesis of a negative impact of longer waiting times prior to commencement of adjuvant radiotherapy could not be confirmed. (orig.)

    Many insurance companies require patient participation in a medically supervised weight management program (WMP) before offering approval for bariatric surgery. Clinical data surrounding benefits of participation are limited. To evaluate the relationship between preoperative insurance-mandated WMP participation and postoperative outcomes in bariatric surgery patients. Regional referral center and teaching hospital. A retrospective review of patients who underwent vertical sleeve gastrectomy or Roux-en-Y gastric bypass between January 2014 and January 2016 was performed. Patients (N = 354) were divided into 2 cohorts and analyzed according to presence (n = 266) or absence (n = 88) of an insurance-mandated WMP requirement. Primary endpoints included rate of follow-up and percent of excess weight loss (%EWL) at postoperative months 1, 3, 6, and 12. All patients, regardless of the insurance-mandated WMP requirement, followed a program-directed preoperative diet. The majority of patients with an insurance-mandated WMP requirement had private insurance (63.9%). Both patient groups experienced a similar proportion of readmissions and reoperations, rate of follow-up, and %EWL at 1, 3, 6, and 12 months (P = NS). Median operative duration and hospital length of stay were also similar between groups. Linear regression analysis revealed no significant improvement in %EWL at 12 months in the yes-WMP group. These data show that patients who participate in an insurance-mandated WMP in addition to completing a program-directed preoperative diet experience no significant benefit to rate of readmission, reoperation, follow-up, or %EWL up to 12 months postoperation. Our findings suggest that undergoing bariatric surgery without completing an insurance-mandated WMP is safe and effective. Copyright © 2018 American Society for Bariatric Surgery.

    Full Text Available Since establishment of Zimbabwe's National Antiretroviral Therapy (ART Programme in 2004, ART provision has expanded from <5,000 to 369,431 adults by 2011. However, patient outcomes are unexplored.To determine improvement in health status, retention and factors associated with attrition among HIV-infected patients on ART.A retrospective review of abstracted patient records of adults ≥ 15 years who initiated ART from 2007 to 2009 was done. Frequencies and medians were calculated for rates of retention in care and changes in key health status outcomes at 6, 12, 24 and 36 months respectively. Cox proportional hazards models were used to determine factors associated with attrition.Of the 3,919 patients, 64% were female, 86% were either WHO clinical stage III or IV. Rates of patient retention at 6, 12, 24 and 36 months were 90.7%, 78.1%, 68.8% and 64.4%, respectively. After ART initiation, median weight gains at 6, 12, and 24 months were 3, 4.5, and 5.0 kgs whilst median CD4+ cell count gains at 6, 12 and 24 months were 122, 157 and 279 cells/µL respectively. Factors associated with an increased risk of attrition included male gender (AHR 1.2; 95% CI, 1.1-1.4, baseline WHO stage IV (AHR 1.7; 95% CI, 1.1-2.6, lower baseline body weight (AHR 2.0; 95% CI, 1.4-2. 8 and accessing care from higher level healthcare facilities (AHR 3.5; 95% 1.1-11.2.Our findings with regard to retention as well as clinical and immunological improvements following uptake of ART, are similar to what has been found in other settings. Factors influencing attrition also mirror those found in other parts of sub-Saharan Africa. These findings suggest the need to strengthen earlier diagnosis and treatment to further improve treatment outcomes. Whilst decentralisation improves ART coverage it should be coupled with strategies aimed at improving patient retention.

    Purpose: To determine the effects of three changes in radiotherapy technique on the outcomes for patients irradiated postoperatively for maxillary sinus cancer. Methods and Materials: The data of 146 patients treated between 1969 and 2002 were reviewed. The patients were separated into two groups according to the date of treatment. Group 1 included 90 patients treated before 1991 and Group 2 included 56 patients treated after 1991, when the three changes were implemented. The outcomes were compared between the two groups. Results: No differences were found in the 5-year overall survival, recurrence-free survival, local control, nodal control, or distant metastasis rates between the two groups (51% vs. 62%, 51% vs. 57%, 76% vs. 70%, 82% vs. 83%, and 28% vs. 17% for Groups 1 and 2, respectively). The three changes were to increase the portals to cover the base of the skull in patients with perineural invasion, reducing their risk of local recurrence; the addition of elective neck irradiation in patients with squamous or undifferentiated histologic features, improving the nodal control, distant metastasis, and recurrence-free survival rates (64% vs. 93%, 20% vs. 3%, and 45% vs. 67%, respectively; p < 0.05 for all comparisons); and improving the dose distributions within the target volume, reducing the late Grade 3-4 complication rates (34% in Group 1 vs. 8% in Group 2, p = 0.014). Multivariate analysis revealed advancing age, the need for enucleation, and positive margins as independent predictors of worse overall survival. The need for enucleation also predicted for worse local control. Conclusion: The three changes in radiotherapy technique improved the outcomes for select patients as predicted. Despite these changes, little demonstrable overall improvement occurred in local control or survival for these patients and additional work must be done

    Psychological symptoms are highly prevalent in patients with shoulder complaints. Psychological symptoms in patients with shoulder complaints might play a role in the aetiology, perceived disability and pain and clinical outcome of treatment. The aim of this study was to assess whether preoperative symptoms of distress, depression, anxiety and somatisation were associated with a change in function after shoulder surgery and postoperative patient perceived improvement of pain and function. In addition, the change of psychological symptoms after shoulder surgery was analyzed and the influence of postoperative symptoms of psychological disorders after surgery on the change in function after shoulder surgery and perceived postoperative improvement of pain and function. A prospective longitudinal cohort study was performed in a general teaching hospital. 315 consecutive patients planned for elective shoulder surgery were included. Outcome measures included change of Disabilities of the Arm, Shoulder and Hand (DASH) score and anchor questions about improvement in pain and function after surgery. Psychological symptoms were identified before and 12 months after surgery with the validated Four-Dimensional Symptom Questionnaire (4DSQ). Psychological symptoms were encountered in all the various shoulder diagnoses. Preoperative symptoms of psychological disorders persisted after surgery in 56% of patients, 10% of patients with no symptoms of psychological disorders before surgery developed new psychological symptoms. Preoperative symptoms of psychological disorders were not associated with the change of DASH score and perceived improvement of pain and function after shoulder surgery. Patients with symptoms of psychological disorders after surgery were less likely to improve on the DASH score. Postoperative symptoms of distress and depression were associated with worse perceived improvement of pain. Postoperative symptoms of distress, depression and somatisation were

    The prevalence of pediatric obstructive sleep apnea (OSA) has increased concurrently with the increasing prevalence of obesity. We have previously validated a short questionnaire predicting the occurrence of OSA on polysomnography (PSG). This follow-up study assessed the utility of the questionnaire in predicting postoperative outcomes. Children undergoing surgery and completing a sleep study were prospectively screened for OSA using a short questionnaire. Procedures within 1 year of PSG were included in the analysis. Questionnaires were scored according to a cutoff previously deemed optimal for predicting OSA (apnea-hypopnea index ≥ 5) on the sleep study. Postoperative outcomes included prolonged (>60 min) length of stay (LOS) in the post-anesthesia care unit (PACU) and oxygen requirement in the PACU. The study cohort included 185 patients (100/85 male/female) age 8 ± 4 years, undergoing adenotonsillectomy (n = 109), other ear, nose, and throat (ENT) procedures (n = 18), or non-ENT procedures (n = 58). There were 45 patients with OSA documented by PSG and 122 patients identified as likely to have OSA according to questionnaire responses (89% sensitivity, 41% specificity). PACU LOS was prolonged in 55/181 (30%) cases and supplemental oxygen was used in the PACU in 29/181 (16%) cases. In separate multivariable models, supplemental oxygen use in the PACU was more common if a patient scored ≥2/6 points on the short questionnaire scale (OR = 5.0; 95% CI: 1.3, 19.9; p = 0.023) or if the patient was diagnosed with OSA on PSG (OR = 4.6; 95% CI: 1.6, 13.5; p = 0.005). Neither OSA on PSG nor questionnaire score ≥2/6 were associated with prolonged PACU stay. Both OSA diagnosis based on the AHI and the questionnaire scale achieved comparable predictive value for the need for oxygen use in the PACU. The utility of the questionnaire in predicting rare adverse events (e.g., unplanned admission or rapid response team activation) remains to be determined

    Full Text Available The incidence and prevalence of cardiovascular disease (CVD are increasing rapidly in developing countries. Most patients with CVD do not respond to medical treatment and have to undergo cardiac surgery. This highly stressful experience results in increased levels of anxiety for patients. The objective of this review was to evaluate the efficacy of massage therapy on postoperative outcomes among patients undergoing cardiac surgery. A comprehensive literature search was made on PubMed-Medline, CINAHL, Science Direct, Scopus, Web of Science and the Cochrane library databases for original research articles published between 2000 and 2015. Original articles that reported the efficacy of massage therapy in patients undergoing cardiac surgery were included. The Cochrane data extraction form was used to extract data. A total of 297 studies were identified in the literature search. However, only seven studies were eligible for analysis. Of the seven studies, six studies demonstrated the effects of massage therapy on improving post-operative outcomes of patients, while one study found no evidence of improvement. Although the methods varied considerably, most of the studies included in this review reported positive results. Therefore, there is some evidence that massage therapy can lead to positive postoperative outcomes. Evidence of the effectiveness of massage therapy in patients undergoing cardiac surgery remains inconclusive. Additional research is needed to provide a strong evidence base for the use of massage therapy to improve post-operative outcomes and recovery among cardiac surgery patients

    This study aims to evaluate the efficacy of processed images to predict postoperative appearance following levator resection. Analysis involved 109 eyes from 65 patients with blepharoptosis who underwent advancement of levator aponeurosis and Müller's muscle complex (levator resection). Predictive images were prepared from preoperative photographs using the image processing software (Adobe Photoshop ® ). Images of selected eyes were digitally enlarged in an appropriate manner and shown to patients prior to surgery. Approximately 1 month postoperatively, we surveyed our patients using questionnaires. Fifty-six patients (89.2%) were satisfied with their postoperative appearances, and 55 patients (84.8%) positively responded to the usefulness of processed images to predict postoperative appearance. Showing processed images that predict postoperative appearance to patients prior to blepharoptosis surgery can be useful for those patients concerned with their postoperative appearance. This approach may serve as a useful tool to simulate blepharoptosis surgery.

    Surgical site infection (SSI) is an important complication after spine surgery. The management of SSI is characterized by significant variability, and there is little guidance regarding an evidence-based approach. The objective of this study was to identify risk factors associated with treatment failure of SSI after spine surgery. A total of 225 consecutive patients with SSI after spine surgery between July 2005 and July 2010 were studied retrospectively. Patients were treated with aggressive surgical debridement and prolonged antibiotic therapy. Outcome and risk factors were analyzed in 197 patients having 1 year of follow-up. Treatment success was defined as resolution within 90 days. A total of 126 (76 %) cases were treated with retention of implants. Forty-three (22 %) cases had treatment failure with five (2.5 %) cases resulting in death. Lower rates of treatment success were observed with late infection (38 %), fusion with fixation to the ilium (67 %), Propionibacterium acnes (43 %), poly microbial infection (68 %), >6 operated spinal levels (67 %), and instrumented cases (73 %). Higher rates of early resolution were observed with superficial infection (93 %), methicillin-sensitive Staphylococcus aureus (95 %), and failure. Superficial infection and methicillin-sensitive Staphylococcus aureus were predictors of early resolution. Postoperative spine infections were treated with aggressive surgical debridement and antibiotic therapy. High rates of treatment failure occurred in cases with late infection, long instrumented fusions, polymicrobial infections, and Propionibacterium acnes. Removal of implants and direct or staged re-implantation may be a useful strategy in cases with high risk of treatment failure.

    Bile leakage, while rare, can be a complication seen after cholecystectomy. It may also occur after hepatic or biliary surgical procedures. Etiology may be underlying pathology or surgical complication. Endoscopic retrograde cholangiopancreatography (ERCP) can play major role in diagnosis and treatment of bile leakage. Present study was a retrospective analysis of outcomes of ERCP procedure in patients with bile leakage. Patients who underwent ERCP for bile leakage after surgery between 2008 and 2012 were included in the study. Etiology, clinical and radiological characteristics, and endoscopic treatment outcomes were recorded and analyzed. Total of 31 patients (10 male, 21 female) were included in the study. ERCP was performed for bile leakage after cholecystectomy in 20 patients, after hydatid cyst operation in 10 patients, and after hepatic resection in 1 patient. Clinical signs and symptoms of bile leakage included abdominal pain, bile drainage from percutaneous drain, peritonitis, jaundice, and bilioma. Twelve (60%) patients were treated with endoscopic sphincterotomy (ES) and nasobiliary drainage (NBD) catheter, 7 patients (35%) were treated with ES and biliary stent (BS), and 1 patient (5%) was treated with ES alone. Treatment efficiency was 100% in bile leakage cases after cholecystectomy. Ten (32%) cases of hydatid cyst surgery had subsequent cystobiliary fistula. Of these patients, 7 were treated with ES and NBD, 2 were treated with ES and BS, and 1 patient (8%) with ES alone. Treatment was successful in 90% of these cases. ERCP is an effective method to diagnose and treat bile leakage. Endoscopic treatment of postoperative bile leakage should be individualized based on etiological and other factors, such as accompanying fistula.

    The outcomes and toxicities of locoregionally recurrent non-small-cell lung cancer (NSCLC) patients treated with curative radiotherapy were evaluated in the modern era. Fifty-seven patients receiving radical radiotherapy for locoregionally recurrent NSCLC without distant metastasis after surgery from 2004 to 2014 were reviewed. Forty-two patients were treated with concurrent chemoradiotherapy (CCRT), and 15 patients with radiotherapy alone. The median radiation dose was 66 Gy (range, 45 to 70 Gy). Lung function change after radiotherapy was evaluated by comparing pulmonary function tests before and at 1, 6, and 12 months after radiotherapy. Median follow-up was 53.6 months (range, 12.0 to 107.5 months) among the survivors. The median overall survival (OS) and progression-free survival (PFS) were 54.8 months (range, 3.0 to 116.9 months) and 12.2 months (range, 0.8 to 100.2 months), respectively. Multivariate analyses revealed that single locoregional recurrence focus and use of concurrent chemotherapy were significant prognostic factors for OS (p = 0.048 and p = 0.001, respectively) and PFS (p = 0.002 and p = 0.026, respectively). There was no significant change in predicted forced expiratory volume in one second after radiotherapy. Although diffusing lung capacity for carbon monoxide decreased significantly at 1 month after radiotherapy (p < 0.001), it recovered to pretreatment levels within 12 months. Acute grade 3 radiation pneumonitis and esophagitis were observed in 3 and 2 patients, respectively. There was no chronic complication observed in all patients. Salvage radiotherapy showed good survival outcomes without severe complications in postoperative locoregionally recurrent NSCLC patients. A single locoregional recurrent focus and the use of CCRT chemotherapy were associated with improved survival. CCRT should be considered as a salvage treatment in patients with good prognostic factors.

    Sarcopenia has been proposed to be a prognostic factor of outcomes for various diseases but has not been applied to Crohn's disease (CD). We aimed to assess the impact of sarcopenia on postoperative outcomes after bowel resection in patients with CD. Abdominal computed tomography images within 30 days before bowel resection in 114 patients with CD between May 2011 and March 2014 were assessed for sarcopenia as well as visceral fat areas and subcutaneous fat areas. The impact of sarcopenia on postoperative outcomes was evaluated using univariate and multivariate analyses. Of 114 patients, 70 (61.4%) had sarcopenia. Patients with sarcopenia had a lower body mass index, lower preoperative levels of serum albumin, and more major complications (15.7% vs 2.3%, P = .027) compared with patients without sarcopenia. Moreover, predictors of major postoperative complications were sarcopenia (odds ratio [OR], 9.24; P = .04) and a decreased skeletal muscle index (1.11; P = .023). Preoperative enteral nutrition (OR, 0.13; P = .004) and preoperative serum albumin level >35 g/L (0.19; P = .017) were protective factors in multivariate analyses. The prevalence of sarcopenia is high in patients with CD requiring bowel resection. It significantly increases the risk of major postoperative complications and has clinical implications with respect to nutrition management before surgery for CD.

    Delirium is an acute disturbance of consciousness and cognition that has been shown to be associated with poor outcomes, including increased mortality. We aimed to evaluate outcome after postoperative delirium in a cohort of surgical intensive care unit (SICU) patients. This prospective study was conducted over a 10-month period in a SICU. Postoperative delirium was diagnosed in accordance with the Intensive Care Delirium Screening Checklist (ICDSC). The primary outcome was mortality at 6-month follow-up. Hospital mortality and becoming dependent were considered as secondary outcomes, on the basis of the evaluation of the patient's ability to undertake both personal and instrumental activities of daily living (ADL) before surgery and 6 months after discharge from the SICU. For each dichotomous outcome - hospital mortality, mortality at 6-month follow-up, and becoming dependent - a separate multiple logistic regression analysis was performed, which included delirium as an independent variable. Another outcome analyzed was changes in health-related quality of life, as determined using short-form 36 (SF-36), which was administered before and 6 months after discharge from the SICU. Additionally, for each SF-36 domain, a separate multiple linear regression model was used for each SF-36 domain, with changes in the SF-36 domain as a dependent variable and delirium as an independent variable. Of 775 SICU-admitted adults, 562 were enrolled in the study, of which 89 (16%) experienced postoperative delirium. Delirium was an independent risk factor for mortality at the 6-month follow-up (OR = 2.562, P <0.001) and also for hospital mortality (OR = 2.673, P <0.001). Delirium was also an independent risk factor for becoming dependent for personal ADL (P-ADL) after SICU discharge (OR = 2.188, P <0.046). Moreover, patients who experienced postoperative delirium showed a greater decline in SF-36 domains after discharge, particularly in physical function, vitality, and

    This study was conducted to analyze treatment outcome and prognostic significance of World Health Organization (WHO)-defined thymic epithelial tumor (TET) subtype and to assess optimal radiation target volume in patients receiving surgery and adjuvant radiation therapy with TET. The record of 160 patients with TET, who received surgical resection at the Samsung medical Center, from December 1994 to June 2004, were reviewed. 99 patients were treated with postoperative radiation therapy (PORT). PORT was recommended when patients had more than one findings among suspicious incomplete resection or positive resection margin or Masaoka stage II ∼ IV or WHO tumor type B2 ∼ C. PORT performed to primary tumor bed only with a mean dose of 54 Gy. The prognostic factor and pattern of failure were analyzed retrospectively. The overall survival rate at 5 years was 87.3%. Age (more than 60 years 77.8%, less than 60 years 91.1%; ρ = 0.03), Masaoka stage (I 92.2%, II 95.4%, III 82.1%, IV 67.5%; ρ = 0.001), WHO tumor type (A-B1 96.0%, B2-C 82.3%; ρ = 0.001), Extent of resection (R0 resection 92.3%, R1 or 2 resection 72.6%; ρ = 0.001) were the prognostic factors according to univariate analysis. But WHO tumor type was the only significant prognostic factor according to multivariate analysis. Recurrence was observed in 5 patients of 71 Masoka stage I-III patients who received grossly complete tumor removal (R0, R1 resection ) and PORT to primary tumor bed. Mediastinal recurrence was observed in only one patients. There were no recurrence within irradiation field. WHO tumor type was the important prognostic factor to predict survival of patients with TET. This study suggest that PORT to only primary tumor bed was optimal. To avoid pleura-or pericardium-based recurrence, further study of effective chemotherapy should be investigated

    Preoperative therapy is frequently employed in the management of esophageal adenocarcinoma. However, many patients are found to have advanced pathologic stage and have poor outcomes. A prognostic factor which identifies this patient population before surgery would be desirable, as alternative treatment strategies may be warranted. Between 2/08 and 1/12, 60 evaluable patients with locally advanced esophageal adenocarcinoma enrolled in single-arm phase II trial of induction chemotherapy, surgery, and post-operative adjuvant chemo-radiotherapy (CRT). A clinical stage of T3, N1, or M1a (AJCC 6th) was required for eligibility. Induction chemotherapy with epirubicin 50 mg/m 2 d1, oxaliplatin 130 mg/m 2 d1, and fluorouracil 200 mg/m 2 /day continuous infusion for 3 weeks, was given every 21 days for 3 cycles and was followed by surgical resection. Adjuvant CRT consisted of 50-55 Gy @ 1.8-2.0 Gy/day and 2 cycles of cisplatin (20 mg/m 2 /day) and fluorouracil (1000 mg/m 2 /day) given as 96-h infusions during weeks 1 and 4 of radiotherapy. Dysphagia was assessed at baseline and after induction chemotherapy. Persistent dysphagia was associated with worse distant metastatic control [HR 3.48 (1.43-8.43), p = 0.006], recurrence free survival [HR 3.04 (1.34-6.92), p = 0.008], and overall survival [HR 3.31 (1.43-7.66), p = 0.005]. Persistent dysphagia was associated with more advanced pathologic T descriptor (pT) (p = 0.048) and N descriptor (pN) (p = 0.002), a greater median number of involved lymph nodes (3 v 1, p = 0.003), and greater residual tumor viability (p = 0.05). No patients with persistent dysphagia had pT0-T2 or pN0 disease. Persistent dysphagia after induction chemotherapy is associated with more advanced pathologic stage and inferior outcomes.

    Post-operative sleep disturbance, with suppression of rapid eye movement sleep and slow wave sleep followed by a subsequent rebound, seems to be related to the magnitude of trauma and thereby to the surgical stress response. In this context, cortisol, autonomic stimulation, and certain cytokines...... may lead to abnormal sleep. Furthermore, the environment, pain and the administration of analgesics seem to be important factors in the precipitation of sleep abnormalities. Post-operative sleep disturbance may contribute to the development of episodic hypoxaemia, haemodynamic instability and altered...... mental status, all of which have an influence on post-operative morbidity and mortality. Prevention or reduction of the post-operative sleep disturbance may be achieved by minimizing surgical trauma, changing the conventional nursing procedures, avoiding opioids and treating pain with non...

    Full Text Available Background: The aim of this prospective audit was to investigate clinical practice related to muscle relaxant reversal and the impact made by the recent introduction of sugammadex on patient outcome at a tertiary teaching hospital. Methods: Data from all patients intubated at our institution during two epochs of seven consecutive days each was collected prospectively. Directly prior to extubation, the train-of-four (TOF ratio was assessed quantitatively by an independent observer. Postoperative outcome parameters were complications in the recovery room and radiological diagnosed atelectasis or pneumonia within 30 days. Results: Data from 146 patients were analysed. Three reversal strategies were used: no reversal, neostigmine or sugammadex. The TOF ratio was less than 0.7 in 17 patients (nine no reversal, eight neostigmine and less than 0.9 in 47 patients (24 no reversal, 19 neostigmine, four sugammadex. Those reversed with sugammadex showed fewer episodes of postoperative oxygen desaturation (15% vs. 33%; P<0.05. TOF ratios of less than 0.7 ( P<0.05 and also <0.9 ( P<0.01 were more likely associated with X-ray results consistent with postoperative atelectasis or pneumonia. Conclusions: Our results suggest a significant impact of residual paralysis on patient outcome. The use of sugammadex resulted in the lowest incidence of residual paralysis.

    Primary aldosteronism causes hypertension and hypokalemia and is often surgically treatable. Diagnosis includes elevated plasma aldosterone, suppressed plasma renin activity, and elevated aldosterone renin ratio. Adrenalectomy improves hypertension and hypokalemia. Postoperative plasma aldosterone and plasma renin activity may be useful in documenting cure or failure. A retrospective analysis of patients who underwent adrenalectomy for primary aldosteronism from 2010 to 2016 was performed, analyzing preoperative and postoperative plasma aldosterone, plasma renin activity, hypertension, and hypokalemia. The utility of postoperative testing was assessed. Clinical cure was defined as improved hypertension control and resolution of potassium loss. Biochemical cure was defined as aldosterone renin ratio reduction to <23.6. Forty-four patients were included; 20 had plasma aldosterone and plasma renin activity checked on postoperative day 1. In the study, 40/44 (91%) were clinically cured. All clinical failures had of biochemical failure at follow-up. Postoperative day 1aldosterone renin ratio <23.6 had PPV of 95% for clinical cure. Cured patients had mean plasma aldosterone drop of 33.1 ng/dL on postoperative day 1; noncured patient experienced 3.9 ng/dL increase. A cutoff of plasma aldosterone decrease of 10 ng/dL had high positive predictive value for clinical cure. Changes in plasma aldosterone and plasma renin activity after adrenalectomy correlate with improved hypertension and hypokalemia. The biochemical impact of adrenalectomy manifests as early as postoperative day 1. We propose a plasma aldosterone decrease of 10 ng/dL as a criterion to predict clinical cure.

    Coma is a state of profound unresponsiveness that can occur as a serious perioperative complication. The study of risk factors for, and sequelae of, postoperative coma has been limited due to the rarity of the event. To determine the incidence, risk factors and impact of postoperative coma in a large patient population. Observational study using a prospectively gathered national dataset. Data from 858 606 patients were analysed. The incidence of postoperative coma of more than 24-h duration was identified. Logistic regression was used to identify independent predictors and develop a risk model of postoperative coma in derivation and validation cohorts; 30-day mortality was also analysed. The incidence of postoperative coma was 0.06%. Multivariate analysis revealed the following independent predictors: liver disease, systemic sepsis, age at least 63 years, renal disease, emergency operation, cardiac disease, hypertension, prior neurological disease, diabetes mellitus and BMI 25 to 29.99 kg m (protective). These predictors were incorporated into a risk index classification; odds ratios for postoperative coma increased from 2.5 with one risk factor to 18.4 with three. Coma was associated with 74.2% all-cause mortality; coma associated with cardiac arrest had a 1.9-fold higher mortality. This is the largest study of postoperative coma ever reported and will be useful for determining risk of coma of more than 24 h duration when evaluating an unresponsive patient following surgery. Data on prognosis will aid medical and ethical decision-making for the comatose surgical patient.

    Purpose: We analyzed long-term local control and complications in patients with either pathologically confirmed or clinical World Health Organization Grade I meningiomas treated with definitive or postoperative radiotherapy (RT) at the University of Florida. Methods: Between 1984 and 2006, 146 patients were treated with definitive (n = 88) or postoperative RT after subtotal resection (n = 57) or gross total resection (n = 1). Patients were treated with conventional (n = 41), stereotactic (n = 103), or intensity-modulated RT (n = 2) to a median dose of 52.7 Gy and followed for a median of 7.3 years (range, 0.6-22.0 years) Results: The local control rates at 5 and 10 years were as follows: definitive RT, 99% and 99%; postoperative RT, 96% and 93%; and overall, 97% and 96%, respectively. The 5- and 10-year cause-specific survival rates were as follows: definitive RT 94% and 94%, postoperative RT, 100% and 96%; and overall, 96% and 95%, respectively. The 5- and 10-year overall survival rates were as follows: definitive RT, 81% and 75%; postoperative RT, 96% and 85%; and overall, 87% and 79%, respectively. Severe RT complications occurred in 6.8% of patients; severe surgery-related complications occurred in 10 (17%) of 58 patients treated surgically. Conclusions: The likelihood of cure after definitive RT or following subtotal resection is excellent. However, a small population of patients experience severe complications, even at the moderate dose used for this disease.

    It is unclear whether adjuvant radiotherapy before or after surgery is effective for locally advanced, resectable lower rectal cancer. This study consists of a prospective randomized trial of postoperative radiotherapy for locally advanced curatively resected lower rectal carcinoma. We divided patients into two groups, one with postoperative 50 Gy radiation therapy to pelvic wall (N=64), and the other with no radiation therapy (N=46). The 5 year disease-free rate was 61.8% in the radiation group and 70.6% in the no radiation group. There was statistically no significant difference between these two groups. The local recurrence rate was 2.7% (radiation therapy group: 1.6%, no radiation therapy group: 4.3%). This local recurrence rate was very low. These results made us suspect that postoperative radiation therapy was not always necessary to prevent local recurrence. Postoperative complications had a higher incidence in the radiation therapy group than in the no-radiation therapy group. In the radiation therapy group, 35.5% of the patients suffered from diarrhea or frequent defecation, and 10.8% from severe abdominal pain. We operated on 4 cases of radiation-induced ileal stenosis and ileus. Postoperative radiation therapy did not help prevent local recurrence even though many complications resulted. (author)

    Full Text Available Background: There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral balloon valvotomy. Methods: In this study, we assessed 15 patients (mean age, 47.7±9.7 years; 11 female and 4 male who underwent mitral valve repair between August 2008 and March 2013 for symptomatic mitral valve restenosis after percutaneous mitral balloon valvotomy. The mean interval between the initial percutaneous mitral balloon valvotomy and the mitral valve repair was 13.5±7 years. The mean preoperative Wilkins score was 9.4±2.6. Results: The mean mitral valve area obtained using planimetry increased from 1.16±0.16 cm2 to 1.62±0.34 cm2 (p=0.0001. The mean pressure half time obtained using Doppler ultrasound decreased from 202.4±58.6 ms to 152±50.2 ms (p=0.0001. The mean pressure gradient obtained using Doppler ultrasound decreased from 9.4±4.0 mmHg to 5.8±1.5 mmHg (p=0.0021. There were no early or late deaths. Thromboembolic events or infective endocarditis did not occur. Reoperations such as mitral valve repair or mitral valve replacement were not performed during the follow-up period (39±16 months. The 5-year event-free survival was 56.16% (95% confidence interval, 47.467–64.866. Conclusion: On the basis of these results, we could not conclude that mitral valve repair could be an alternative for patients with mitral valve restenosis after percutaneous balloon mitral valvotomy. However, some patients presented with results similar to those of mitral valve replacement. Further studies including more patients with long-term follow-up are necessary to determine the possibility of this application of mitral valve repair.

    Chronic low back pain (CLBP) has become one of the most common causes of disability in adults under 45 years of age and is consequently one of the most common reasons for early retirement in industrialised societies. Accordingly, CLBP represents an expensive drain on society's resources and is a very challenging area for which a consensus for rational therapy is yet to be established. The spinal fusion procedure was introduced as a treatment option for CLBP more than 70 years ago. However, few areas of spinal surgery have caused so much controversy as spinal fusion. The literature reveals divergent opinions about when fusion is indicated and how it should be performed. Furthermore, the significance of the role of postoperative rehabilitation following spinal fusion may be underestimated. There exists no consensus on the design of a program specific for rehabilitation. Ideally, for any given surgical procedure, it should be possible to identify not only possible complications relative to a surgical procedure, but also what symptoms may be expected, and what pain behaviour may be expected of a particular patient. The overall aims of the current studies were: 1) to introduce patient-based functional outcome evaluation into spinal fusion treatment; 2) to evaluate radiological assessment of different spinal fusion procedures; 3) to investigate the effect of titanium versus stainless steel pedicle screws on mechanical fixation and bone ingrowth in lumbar spinal fusion; 4) to analyse the clinical and radiological outcome of different lumbar spinal fusion techniques; 5) to evaluate complications and re-operation rates following different surgical procedures; and 6) to analyse the effect of different rehabilitation strategies for lumbar spinal fusion patients. The present thesis comprises 9 studies: 2 clinical retrospective studies, 1 clinical prospective case/reference study, 5 clinical randomised prospective studies and 1 animal study (Mini-pigs). In total, 594 patients

    Quality and patient/parent satisfaction are goals for pediatric perioperative services. As part of the implementation of our operating room electronic medical record (EMR), a postoperative phone call questionnaire was developed to assess patients discharged after outpatient surgery. The goal of this initiative was to determine the rate of common postoperative complications and understand reasons for patient/parent dissatisfaction. Institutional Review Board approval was obtained for chart review. The postoperative phone call survey was attempted by our postanesthesia care unit nursing staff on all pediatric outpatients. The call was attempted for 3 days. From 2009 to 2013, more than 37 000 phone records existed in our EMR, Epic Optime (Epic Systems, Verona, WI). These data were extracted to a business intelligence (BI) program, QlikView (Qliktech, Radnor, PA, USA). A BI dashboard was constructed to obtain phone call results for any given time frame from monthly to spanning several years. Complications were logged as 4-point severity rating scales (none, mild, moderate, severe) with descriptions for each level. The BI dashboard calculated the overall and rates by severity for the following: (i) nausea, (ii) vomiting, (iii) pain, (iv) bleeding, (v) hoarseness, and (vi) difficulty eating. Of 42 688 outpatient cases, 37 620 postoperative phone calls were completed for an overall response rate of 88%. Pain, at 11.1%, was the highest reported postoperative complication. The rate of dissatisfaction was reported to be 0.31%. Most patients reporting dissatisfaction (62%) did not report any complications. Contingency coefficient showed that there was little relationship between satisfaction and presence of complications. A postoperative phone survey is cost-effective and appreciated by patients. We found that satisfaction with our perioperative services was not related to the rates of reported complications. Although reducing complications is of utmost importance

    Clinical study with pre- and postoperative back photographs and postoperative Scoliosis Research Society-22 survey in patients who had undergone surgery for idiopathic scoliosis. To determine the effect of showing patients their photographs before and after surgery for idiopathic scoliosis on postoperative patient satisfaction. After scoliosis surgery, patient satisfaction may be limited because the patients cannot directly see their back and may forget the preoperative appearance. In 60 patients who had undergone surgery for correction of idiopathic scoliosis (Lenke type 1), pre- and postoperative photographs were taken from the anterior, posterior, and right and left lateral views. After surgery, patients in group 1 (30 patients) were shown the preoperative and most recent follow-up photographs, and patients in group 2 (30 patients) had routine evaluation but were not shown their photographs. All patients completed the Scoliosis Research Society-22 survey. Patients in both groups had similar age, sex, distribution of Lenke type and Risser sign, follow-up, and pre- and postoperative Cobb angles and balance (coronal and sagittal). A significant difference was observed between the groups for survey question 10 (which was about self-image), question 18 (which was about function and activity), and question 21 (which was about satisfaction) (P ≤ 0.05). There were no differences between patients in groups 1 and 2 in Scoliosis Research Society-22 domain or total scores. By showing patients the pre- and postoperative clinical photographs, patient satisfaction may be greater, as measured with some SRS-22 scores. This method may enable clinicians to positively change the patients' self-image perception after surgery for correction of scoliosis. 4.

    Full Text Available Introduction: The objective of our study was to describe surgical outcomes of Deloyers procedure in our referral center, and to compare the results of patients with and without protective ileostomy. Methods: Patients undergoing a Deloyers procedure from 2013 to 2016 were prospectively included. General characteristics, intraoperative variables, postoperative course, and functional outcomes were analyzed. Patients were compared into two groups: group (1 patients undergoing Deloyers procedure without ileostomy, and group (2 Deloyers procedure with protective ileostomy. Results: Sixteen patients undergoing isoperistaltic transposition of the right colon remnant were included, of which 9 (63% were males with a median age of 47 (range 22–76 years. The main surgical indication was the restoration of bowel transit (62.5%. There was higher major morbidity rate in the Deloyers procedure with protective ileostomy group, but without statistical significance (20% vs. 9%, p = 0.92. No leaks or deaths were reported. The length of hospital stay was 7 days. The mean number of bowel movements per day was 4 at 18 months of follow up. Only four (25% patients used irregularly loperamide. Conclusions: The Deloyers procedure has satisfactory results and is reproducible with low morbidity. The major and minor morbidity rates were similar between groups, suggesting that the costs and risks of a second procedure can be avoided by providing a safe primary anastomosis. Resumo: Introdução: O objetivo de nosso estudo foi descrever os resultados cirúrgicos do procedimento de Deloyer em nosso centro de referência e comparar os resultados de pacientes com e sem ileostomia de proteção.

    To present the critical features of our postoperative plan for children undergoing delayed primary bladder closure because appropriate postoperative management is crucial to successful exstrophy repair. Using an institutionally approved database, patients with bladder exstrophy whose primary bladder closure was performed at least 1 month after birth were identified. All aspects of the postoperative management were reviewed. A total of 20 patients (18 boys) were identified: 19 with classic bladder extrosphy and 1 with an exstrophy variant. The patients underwent closure at a mean age of 9.9 months. All patients underwent pelvic osteotomy and immobilization for an average of 34.8 days. Analgesia was administered by way of a tunneled epidural catheter in 90% of patients for an average of 18.8 days, and 12 patients (60%) required adjunct intravenous analgesia. Bilateral ureteral catheters and suprapubic tubes were used in all patients. Total parenteral nutrition was administered to 10 (83%) of 12 patients who underwent closure after 2000. All patients received preoperative antibiotics and 2 weeks of postoperative intravenous antibiotics that was followed by oral prophylaxis. The mean hospital stay was 6.3 weeks. With an average follow-up of 7.4 years, delayed closure was 100% successful. Successful delayed primary closure of bladder exstrophy requires a multidisciplinary approach. The keys to success include osteotomy, pelvic immobilization, analgesia, nutritional support, maximal bladder drainage, and infection prophylaxis. Copyright © 2012. Published by Elsevier Inc.

    The aim of this study was to evaluate the impact of cerebral blood flow (CBF) recovery obtained from brain single-photon emission computed tomography (SPECT) images on postoperative outcome after aneurysmal subarachnoid haemorrhage (SAH). Twenty-nine patients who had undergone surgical clipping for ruptured anterior communicating artery aneurysms were analyzed prospectively. Routine measurements of CBF were performed using technetium-99 m hexamethyl propyleneamine oxine SPECT on days 4 and 14 after SAH. Regional voxel data analyzed by three dimensional stereotactic surface projection (3D-SSP) were compared between patients and age-matched normal database (NDB). In 3D-SSP analysis of all patients, cortical hypoperfusion around the surgical site in bilateral frontal lobes was evident on day 4 (P SSP SPECT image analyses can be a potential predictor of poor prognosis in postoperative patients after SAH. © 2017 John Wiley & Sons Australia, Ltd.

    Evidence indicates that impaired immunocompetence and nutritional status adversely affect short-term and long-term outcomes of patients with cancer. We aimed to evaluate the clinical significance of preoperative immunocompetence and nutritional status according to Onodera's prognostic nutrition index (PNI) among patients who underwent curative gastrectomy for gastric cancer (GC).This study included 260 patients with stage II/III GC who underwent R0 resection. The predictive values of preoperative nutritional status for postoperative outcome (morbidity and prognosis) were evaluated. Onodera's PNI was calculated as follows: 10 × serum albumin (g/dL) + 0.005 × lymphocyte count (per mm).The mean preoperative PNI was 47.8. The area under the curve for predicting complications was greater for PNI compared with the serum albumin concentration or lymphocyte count. Multivariate analysis identified preoperative PNI < 47 as an independent predictor of postoperative morbidity. Moreover, patients in the PNI < 47 group experienced significantly shorter overall and disease-free survival compared with those in the PNI ≥ 47 group, notably because of a higher prevalence of hematogenous metastasis as the initial recurrence. Subgroup analysis according to disease stage and postoperative adjuvant treatment revealed that the prognostic significance of PNI was more apparent in patients with stage II GC and in those who received adjuvant chemotherapy.Preoperative PNI is easy and inexpensive to determine, and our findings indicate that PNI served as a significant predictor of postoperative morbidity, prognosis, and recurrence patterns of patients with stage II/III GC.

    Donor safety is the major concern in living donor liver transplantation, although hepatic resection may be associated with postoperative coagulopathy. Recently, the use of sugammadex has been gradually increased, but sugammadex is known to prolong prothrombin time (PT) and activated partial thromboplastin time (aPTT). We compared the postoperative coagulation profiles and outcomes of sugammadex versus pyridostigmine group in donors receiving living donor hepatectomy.Consecutive donor hepatectomy performed between September 2013 and August 2016 was retrospectively analyzed. For reversal of rocuronium-induced neuromuscular blockade, donors received sugammadex 4 mg/kg or pyridostigmine 0.25 mg/kg. The primary end-points were laboratory findings (PT, aPTT, hemoglobin, platelet count) and clinically evaluated postoperative bleeding (relaparotomy for bleeding, cumulative volume collected in drains). Secondary outcomes were anesthesia time, postoperative hospital day.Of 992 donors, 383 treated with sugammadex and 609 treated with pyridostigmine for the reversal of neuromuscular blockade. There were no significant differences between both groups for drop in hemoglobin and platelet, prolongation in PT, aPTT, and the amount of 24-h drain volume. Bleeding events within 24 h were reported in 2 (0.3%) for pyridostigmine group and 0 (0%) for sugammadex group (P = .262). Anesthesia time was significantly longer in pyridostigmine group than that in sugammadex group (438.8 ± 71.4 vs. 421.3 ± 62.3, P sugammadex group (P = .002).Sugammadex 4 mg/kg was not associated with increased bleeding tendency, but associated with reduced anesthesia time and hospital stay. Therefore, sugammadex may be safely used and will decrease morbidity in donor undergoing living-donor hepatectomy.

    The management of asymptomatic patients with mitral regurgitation (MR) remains controversial. Exercise-induced pulmonary hypertension (ExPHT) was recently reported as a strong predictor of rapid onset of symptoms. We hypothesised that ExPHT is a predictor of postoperative cardiovascular events in patients with primary MR. One hundred and two patients with primary MR, no or mild symptoms (New York heart association (NYHA) ≤2), and no LV dysfunction/dilatation, were prospectively recruited in 3 centres and underwent exercise-stress echocardiography. The presence of ExPHT was defined as an exercise systolic pulmonary arterial pressure >60 mm Hg. All patients were closely followed up and operated on when indication for surgery was reached. Postoperative events were defined as the occurrence of atrial fibrillation (AF), stroke, cardiac-related hospitalisation or death. Among the 102 patients included, 59 developed ExPHT (58%). These patients were significantly older than those without ExPHT (p=0.01). During a mean postoperative follow-up of 50±23 months, 28 patients (26%) experienced a predefined cardiovascular event. Patients with ExPHT had significantly higher rate of postoperative events (39% vs 12%, p=0.005); the rate of events was still higher in these patients (32% vs 9%, p=0.013), even when excluding early postoperative AF (ie, within 48 h). Event-free survival was significantly lower in the ExPHT group (all events: 5-year: 60±8% vs 88±5%, p=0.007, events without early AF: 5-year: 67±7% vs 90±4%, p=0.02). Using Cox multivariable analysis, ExPHT remained independently associated with higher risk of postoperative events in all models (all p≤0.04). ExPHT is associated with increased risk of adverse cardiac events following mitral valve surgery in patients with primary MR. Published by the BMJ Publishing Group Limited.

    The aim of this study was to compare audiometric results before and after stapes surgery and identify potential prognostic factors to appropriately select patients with otosclerosis who will most likely benefit from surgery. We enrolled 126 patients with otosclerosis (162 consecutive ears) in our study who underwent stapes surgery between 2007 and 2012 at our institution. Preoperative and postoperative data including pure-tone audiometry, speech audiometry, stapedial reflex audiometry and surgical data were analyzed. The average preoperative air-bone gap (ABG) was 28.9 ± 8.6 dB. Male patients and patients older than 45 years of age had greater preoperative ABGs in comparison to females and younger patients. Postoperative ABGs were 11.2 ± 7.4 dB. The average ABG gain was 17.7 ± 11.1 dB. Preoperative audiometric data, age, gender and type of surgery did not influence the postoperative results. Stapes surgery offers predictable results independent from disease progression or patient-related factors. While absolute values of hearing improvement are instrumental in reflecting audiometric results of a cohort, relative values better reflect individual's audiometric data resembling the patient's benefit.

    Purpose: To directly compare the capabilities of perfusion scan, SPECT, co-registered SPECT/CT, and quantitatively and qualitatively assessed MDCT (i.e. quantitative CT and qualitative CT) for predicting postoperative clinical outcome for lung volume reduction surgery (LVRS) candidates. Materials and methods: Twenty-five consecutive candidates (19 men and six women, age range: 42-72 years) for LVRS underwent preoperative CT and perfusion scan with SPECT. Clinical outcome of LVRS for all subjects was also assessed by determining the difference between pre- and postoperative forced expiratory volume in 1 s (FEV 1 ) and 6-min walking distance (6MWD). All SPECT examinations were performed on a SPECT scanner, and co-registered to thin-section CT by using commercially available software. On planar imaging, SPECT and SPECT/CT, upper versus lower zone or lobe ratios (U/Ls) were calculated from regional uptakes between upper and lower lung fields in the operated lung. On quantitatively assessed CT, U/L for all subjects was assessed from regional functional lung volumes. On qualitatively assessed CT, planar imaging, SPECT and co-registered SPECT/CT, U/Ls were assessed with a 4-point visual scoring system. To compare capabilities of predicting clinical outcome, each U/L was statistically correlated with the corresponding clinical outcome. Results: Significantly fair or moderate correlations were observed between quantitatively and qualitatively assessed U/Ls obtained with all four methods and clinical outcomes (-0.60 ≤ r ≤ -0.42, p < 0.05). Conclusion: Co-registered perfusion SPECT/CT has better correlation with clinical outcome in LVRS candidates than do planar imaging, SPECT or qualitatively assessed CT, and is at least as valid as quantitatively assessed CT.

    Purpose To evaluate mid-term refractive outcomes and higher order aberrations of aspheric PRK for low, moderate and high myopia and myopic astigmatism with the AMARIS excimer laser system (SCHWIND eye-tech-solutions GmbH, Kleinostheim, Germany). Methods This prospective longitudinal study evaluated 80 eyes of 40 subjects who underwent aspheric PRK. Manifest refractive spherical equivalent (MRSE) of up to −10.00 diopters (D) at the spectacle plane with cylinder up to 3.25 was treated. Refractive outcomes and corneal wavefront data (6 mm pupil to the 7th Zernike order) were evaluated out to 2 years postoperatively. Statistical significance was indicated by P  0.05, both cases). There was a statistical increase in postoperative coma (+0.12 μm) and spherical aberration (+0.14 μm) compared to preoperatively (P < 0.001, both cases). Conclusion Aspheric PRK provides excellent visual and refractive outcomes with induction in individual corneal aberrations but not overall corneal aberrations.

    Tricuspid regurgitation (TR) is common in patients with heart failure undergoing left ventricular assist device (LVAD) implantation. Whether the TR should be surgically managed at the time of LVAD surgery is controversial. We searched SCOPUS, Web of Science, Ovid EMBASE, and Ovid MEDLINE (through May 10, 2014) for randomized controlled trials and observational studies comparing postoperative outcomes in patients treated with LVAD with concomitant tricuspid valve surgery (TVS) compared with LVAD alone. Six observational studies including 3,249 patients compared outcomes following LVAD + TVS versus LVAD. Four studies were single-center and most did not adjust for potential confounders. Addition of TVS prolonged cardiopulmonary bypass times by an average of 31 minutes (three studies, 95% CI 20-42). There was no difference in need for right ventricular assist device (six studies, HR 1.42, 95% CI 0.54-3.76), acute renal failure (four studies, HR 1.07, 95% CI 0.55-2.10), or early mortality (six studies, HR 1.28, 95% CI 0.78-2.08) in patients treated with LVAD + TVS versus LVAD alone. TVS prolongs cardiopulmonary bypass times, but available data demonstrate no significant association with early postoperative outcomes. However, differences in baseline risk of patients treated with TVS versus not limit our ability to draw conclusions.

    Full Text Available ObjectivesClinical trials of either pulmonary perfusion or ventilation during cardiopulmonary bypass are equivocal. We hypothesized that to achieve significant improvement in outcomes both interventions had to be concurrent.DesignRetrospective case-control studySettingsMajor academic tertiary referral medical centerParticipants274 consecutive patients who underwent open heart surgery with cardiopulmonary bypass 2009 - 2013.InterventionsThe outcomes of 86 patients who received pulmonary perfusion and ventilation during cardiopulmonary bypass were retrospectively compared to the control group of 188 patients.Measurements and Main ResultsRespiratory complications rates were similar in both groups (33.7% vs. 33.5%, as were the rates of postoperative pneumonia (4.7% vs. 4.3%, pleural effusions (13.9% vs. 12.2% and re-intubations (9.3% vs. 9.1%. Rates of adverse postoperative cardiac events including ventricular tachycardia (9.3% vs. 8.5% and atrial fibrillation (33.7% vs. 28.2% were equivalent in both groups. Incidence of sepsis (8.1% vs. 5.3%, postoperative stroke (2.3% vs. 2.1%, acute kidney injury (2.3% vs. 3.7% and renal failure (5.8% vs. 3.7% were likewise comparable. Despite similar transfusion requirements, coagulopathy (12.8% vs. 5.3%, p=0.031 and the need for mediastinal re-exploration (17.4% vs. 9.6%, p=0.0633 were observed more frequently in the pulmonary perfusion and ventilation group, but the difference did not reach the statistical significance. ICU and hospital stays, and the ICU readmission rates (7.0% vs. 8.0% were similar in both groups.ConclusionsSimultaneous pulmonary perfusion and ventilation during cardiopulmonary bypass were not associated with improved clinical outcomes.

    To compare early versus delayed postoperative feeding in women undergoing major gynaecological surgery with regard to clinical outcomes, duration of postoperative stay, and patient satisfaction. We conducted a parallel-randomized controlled trial at a tertiary care centre in Montreal, Quebec, between June 2000 and July 2001. Patients undergoing major gynaecological surgery were randomized following a 1:1 allocation ratio to receive either early postoperative feeding in which oral clear fluids were begun up to six hours after surgery followed by solid foods as tolerated, or delayed postoperative feeding, in which clear fluids were begun on the first postoperative day and solid foods on the second or third day as tolerated. The primary outcomes analyzed were duration of postoperative stay and patient satisfaction. Secondary outcomes included mean time to appetite, passage of flatus, and bowel movement, as well as the presence of symptoms of paralytic ileus. A total of 119 patients were randomized; 61 patients were assigned to the early feeding group and 58 to the delayed feeding group. Demographic characteristics, including age, weight, smoking status, and prior surgical history were comparable between both groups. There was no difference in length of postoperative stay between the two groups (86.4 ± 21.0 hours in the early feeding group vs. 85.6 ± 26.2 hours in the delayed feeding group; P > 0.05). No significant difference was noted in patient satisfaction (P > 0.05). No difference was found in the frequency of postoperative ileus, mean time to appetite, passage of flatus, or first bowel movement. The introduction of early postoperative feeding appears to be safe and well tolerated by patients undergoing major gynaecological surgery. The duration of postoperative stay, patient satisfaction, and gastrointestinal symptoms are comparable between patients undergoing early or delayed postoperative feeding.

    The long-term postoperative improvement of quality of life (QOL) and employment were investigated in patients undergoing resection of epileptogenic lesions detected by magnetic resonance (MR) imaging to identify the associated preoperative factors. Thirty of 47 patients who underwent lesionectomy between 1987-2001 replied to questionnaires. Patients with extratemporal resection outnumbered those with temporal lobe resection. The mean follow-up period was 12.4±3.7 years. An arbitrary score for quantitatively assessing QOL was assigned. The mean increases in QOL score points were significantly higher in the late childhood onset group than those in the early childhood onset group, and were also significantly higher in the temporal resection group and extratemporal resection of non-dysplastic cortical pathology group than in the extratemporal resection of dysplastic cortical pathology group. Postoperative QOL improvement and occupational status of patients depended on the completeness of seizure control. Resection of lesions detected by MR imaging in patients with intractable epilepsy resulted in effective long-term QOL improvement and postoperative occupational status. Favorable outcome was related mainly to the pathology of the epileptogenic lesions, whether the lesion site was temporal or extratemporal, and the completeness of seizure control. (author)

    With an unequalled contraceptive prevalence rate in sub-Saharan Africa, of 43% among currently married women in Zimbabwe, the Central Statistical Office (1989) observed that fertility has declined sharply in recent years. Using data from several surveys on Zimbabwe, especially the birth histories of the Zimbabwe Demographic and Health Survey, this study examines fertility trends in Zimbabwe. The results show that the fertility decline in Zimbabwe is modest and that the decline is concentrated among high order births. Multivariate analysis did not show a statistically significant effect of contraception on fertility, partly because a high proportion of Zimbabwean women in the reproductive age group never use contraception due to prevailing pronatalist attitudes in the country.

    Hysterectomy for enlarged uteri is a surgical challenge. Our aim was to compare perioperative outcomes, cosmesis, and postoperative quality of life following laparoscopic hysterectomy for large uteri using minilaparoscopic 3-mm versus conventional laparoscopic 5-mm instruments. We prospectively enrolled women with a uterus between 16 and 20 weeks of gestation at the preoperative examination. These patients underwent laparoscopic procedures using either 3-mm (minilaparoscopy group) or 5-mm (standard laparoscopy group) instruments. Five months after surgery, patients were called back to fill out the validated Italian translation of the Short Form 12-item Health Survey. Data about the cosmetic outcome of the procedure were also collected, using a Numeric Rating Scale (NRS) from 0 to 10. Seventy-eight women were included (27 in the 3-mm and 51 in the 5-mm groups). Perioperative characteristics were comparable between groups. The median uterus weight was 575 (range, 440-1050) g and 550 (400-1000) g in the 3-mm and 5-mm groups, respectively. No minilaparoscopic procedure was converted to standard 5-mm or to an open approach. One (2%) conversion to open abdominal surgery was needed in the conventional laparoscopy group. A better subjective cosmetic outcome was found in the 3-mm (NRS, 9.7 ± 0.4) versus the 5-mm (NRS, 8.9 ± 1.2) group (P=.01). Postoperative quality of life was comparable between groups. Minilaparoscopic hysterectomy is feasible, even in the case of an enlarged-size uterus. Moreover, it is associated with a better cosmetic outcome, compared with conventional laparoscopy.

    To investigate the effect of general or regional anesthesia on postoperative cardiopulmonary complications and inpatient mortality after hip fracture surgery in elderly patients. A retrospective analysis was conducted according to the medical records of 572 elderly patients with hip fractures admitted to our hospital from January 1, 2005 to December 31, 2014. The age, gender, preoperative comorbidities, length of preoperative bedridden time, mechanism of injury, surgical types, anesthetic methods, major postoperative complications and inpatient mortality were recorded. Multivariate Logistic regression analysis was applied to analyze the impact of different anesthetic methods on inpatient mortality in these patients. Of the 572 patients, 392 (68.5%) received regional anesthesia. Inpatient death occurred in 8 (8/572, mortality: 1.4%), including 5 cases of RA group (5/392, mortality: 1.3%) and 3 cases of GA group (3/180, mortality: 1.7%). There was no statistically significant difference between the two groups in inpatient mortality (P>0.05). Multiple Logistic regression analysis showed that gender (odds ratio: 0.18, 95% CI: 0.03-1.05, P=0.057), age (odds ratio: 1.22, 95% CI: 1.07-1.38, P=0.002), preoperative pulmonary comorbidities (odds ratio: 12.09, 95% CI: 2.28-64.12, P=0.003) and surgical types (odds ratio: 9.36, 95% CI: 1.34-64.26, P=0.024) were risk factors for inpatient mortality. Postoperative cardiovascular complications occurred in 36 patients (36/572, morbidity: 6.3%), with 19 patients in RA group (19/392, morbidity: 4.8%),and 17 patients in GA group (17/180, morbidity: 9.4%). Multiple Logistic regression analysis showed that age (odds ratio: 1.13, 95% CI: 1.07-1.19, Pbedridden time (odds ratio: 1.11, 95% CI: 1.04-1.18, P=0.003) and anesthetic methods (odds ratio: 5.86, 95% CI: 2.98-11.53, Pelderly patients. Regional anesthesia is associated with a lower risk of pulmonary complications after surgical procedure compared with general anesthesia.

    One of the factors contributing to long-term outcome of posterior malleolar fractures is the development of osteoarthritis. Based on biomechanical, cadaveric, and small population studies, fixation of posterior malleolar fracture fragments (PMFFs) is usually performed when fragment size exceeds 25-33%. However, the influence of fragment size on long-term clinical and radiological outcome size remains unclear. A retrospective cohort study of 131 patients treated for an isolated ankle fracture with involvement of the posterior malleolus was performed. Mean follow-up was 6.9 (range, 2.5-15.9) years. Patients were divided into groups depending on size of the fragment, small (25%, n = 25), and presence of step-off after operative treatment. We have compared functional outcome measures (AOFAS, AAOS), pain (VAS), and dorsiflexion restriction compared to the contralateral ankle and the incidence of osteoarthritis on X-ray. There were no nonunions, 56% of patients had no radiographic osteoarthritis, VAS was 10 of 100, and median clinical score was 90 of 100. More osteoarthritis occurred in ankle fractures with medium and large PMFFs compared to small fragments (small 16%, medium 48%, large 54%; P = .006). Also when comparing small with medium-sized fragments (P = .02), larger fragment size did not lead to a significantly decreased function (median AOFAS 95 vs 88, P = .16). If the PMFF size was >5%, osteoarthritis occurred more frequently when there was a postoperative step-off ≥1 mm in the tibiotalar joint surface (41% vs 61%, P = .02) (whether the posterior fragment had been fixed or not). In this group, fixing the PMFF did not influence development of osteoarthritis. However, in 42% of the cases with fixation of the fragment a postoperative step-off remained (vs 45% in the group without fixation). Osteoarthritis is 1 component of long-term outcome of malleolar fractures, and the results of this study demonstrate that there was more radiographic osteoarthritis in

    Either enucleation or more extended resection is performed to treat patients with pancreatic neuroendocrine tumor (pNET). Aim was to analyze the postoperative complications for each operation separately. Furthermore, independent risk factors for complications and incidence of pancreatic insufficiency were analyzed. Retrospective all resected patients from two academic hospitals in The Netherlands between 1992 and 2013 were included. Postoperative complications were scored by both ISGPS and Clavien-Dindo criteria. Based on tumor location, operations were compared. Independent risk factors for overall complications were identified. During long-term follow-up, pancreatic insufficiency and recurrent disease were analyzed. Tumor enucleation was performed in 60/205 patients (29%), pancreatoduodenectomy in 65/205 (31%), distal pancreatectomy in 72/205 (35%) and central pancreatectomy in 8/205 (4%) patients. Overall complications after tumor enucleation of the pancreatic head and pancreatoduodenectomy were comparable, 24/35 (69%) versus 52/65 (80%). The same was found after tumor enucleation and resection of the pancreatic tail (36 vs.58%). Number of re-interventions and readmissions were comparable between all operations. After pancreatoduodenectomy, 33/65 patients had lymph node metastasis and in patients with tumor size ≤2 cm, 55% had lymph node metastasis. Tumor in the head and BMI ≥25 kg/m(2) were independent risk factors for complications after enucleation. During follow-up, incidence of exocrine and endocrine insufficiency was significant higher after pancreatoduodenectomy (resp. 55 and 19%) compared to the tumor enucleation and distal pancreatectomy (resp. 5 and 7% vs. 8 and 13%). After tumor enucleation 19% developed recurrent disease. Since the complication rate, need for re-interventions and readmissions were comparable for all resections, tumor enucleation may be regarded as high risk. Appropriate operation should be based on tumor size, location, and

    To describe surgical technique, postoperative complications, and visual outcome in penguins after phacoemulsification lens extraction surgery. Twenty-one penguins (27 eyes) that had phacoemulsification from 2011 to 2015 at Animal Eye Associates. Species included are as follows: 14 southern Rockhopper (18 eyes, 66.6%), 4 Gentoo (4 eyes, 19%), 2 King (3 eyes, 9.5%), and 1 Chinstrap penguin (2 eyes, 4.8%). Eleven of the penguins were females, and 10 were males with average age at the time of surgery being 27.5 years (range of 22-31 years). This is a retrospective study of phacoemulsification cataract surgery patients from 2011 to 2015. Visual outcome was evaluated by veterinary ophthalmologists at postoperative recheck examinations and subjectively by penguin keepers using individual bird surveys and paired t tests for statistical analysis. All eyes were functionally visual after surgery and at the time of last follow-up. Based on keeper surveys, 81% (17/21) of penguins showed immediate improvements in overall quality of life and 90% (19/21) of penguins exhibited improvement in mobility and behavior within their exhibit following cataract removal. Of the 14 penguins that received 1:5 intracameral atracurium during surgery, 10 (71.4%) had moderate mydriasis, 1 (7.1%) had minimal mydriasis, and 3 (21.4%) showed no effect to the pupil. Seventy percent of the cases had phacoemulsification times less than 60 seconds/eye; the mean time was 72 seconds. Sixteen eyes (59.3%) underwent anterior capsulotomy only, planned anterior and posterior capsulotomies were performed in 3 eyes (11.1%), and the entire lens capsule was removed due to capsular fibrosis and wrinkling in 8 eyes (29.6%). The most common short-term postoperative complication was temporary mild blepharospasm and/or epiphora, reported in 8 eyes (29.6%) from 7 penguins (33.3%). Long-term complications, 2-6 years postoperatively, included posterior synechiation resulting in dyscoria (10 of 24 eyes, 41.7%) and

    To compare tourniquet application and epinephrine injection for hemostasis during hypospadias surgery in terms of bleeding and complications. Between April 2013 and September 2014, patients who were admitted for hypospadias repair were divided by random allocation into either a diluted epinephrine injection (DE) group or tourniquet application (T) group for hemostasis during the procedure. In the T group, a rubber band was applied at the base of the penis after skin dissection, and in the DE group, epinephrine 1/100,000 was injected along the incision lines. The patients' ages, urethral defect lengths, pre-operative, intraoperative and postoperative variables were compared between the two groups. A total of 70 patients (35 in each group) were enrolled into the study. The mean ages and preoperative variables were not significantly different. Average blood loss was 23.51 ± 15.36 cc in the tourniquet group and 15.99 ± 10.00 cc in the epinephrine group, and was significantly higher in tourniquet group (P = 0.022); however, the mean operative time was not significantly different. Postoperative complications, described as Clavian classification, were reported in eight patients (23%) in the T group and 10 patients (30%) in the DE group, which was not significantly different. Epinephrine injections minimize operative bleeding without significant harmful effects on postoperative outcomes; therefore, it could be considered to be a safe and effective method for preparation of a bloodless field during hypospadias surgery.

    National quality programs have been implemented to decrease the burden of adverse events on key outcomes in bariatric surgery. However, it is not well understood which complications have the most impact on patient health. To quantify the impact of specific bariatric surgery complications on key clinical outcomes. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. Data from patients who underwent primary bariatric procedures were retrieved from the MBSAQIP 2015 participant use file. The impact of 8 specific complications (bleeding, venous thromboembolism [VTE], leak, wound infection, pneumonia, urinary tract infection, myocardial infarction, and stroke) on 5 main 30-day outcomes (end-organ dysfunction, reoperation, intensive care unit admission, readmission, and mortality) was estimated using risk-adjusted population attributable fractions. The population attributable fraction is a calculated measure taking into account the prevalence and severity of each complication. The population attributable fractions represents the percentage reduction in a given outcome that would occur if that complication were eliminated. In total, 135,413 patients undergoing sleeve gastrectomy (67%), Roux-en-Y gastric bypass (29%), adjustable gastric banding (3%), and duodenal switch (1%) were included. The most common complications were bleeding (.7%), wound infection (.5%), urinary tract infection (.3%), VTE (.3%), and leak (.2%). Bleeding and leak were the largest contributors to 3 of 5 examined outcomes. VTE had the greatest effect on readmission and mortality. This study quantifies the impact of specific complications on key surgical outcomes after bariatric surgery. Bleeding and leak were the complications with the largest overall effect on end-organ dysfunction, reoperation, and intensive care unit admission after bariatric surgery. Furthermore, our findings suggest that an initiative targeting reduction of post-bariatric surgery

    Several prognostic scores were designed in order to estimate the risk of postoperative adverse events. None of them includes a component directly associated to the nutritional status. The aims of the study were the evaluation of performance of risk-adjusted models for early outcomes after oesophagectomy and to develop a score for severe complication prediction with special consideration regarding nutritional status. A comparison of POSSUM and Charlson score and their derivates, ASA, Lagarde score and nutritional index (PNI) was performed on 167 patients undergoing oesophagectomy for cancer. A logistic regression model was also estimated to obtain a new prognostic score for severe morbidity prediction. Overall morbidity was 35.3% (59 cases), severe complications (grade III-V of Clavien-Dindo classification) occurred in 20 cases. Discrimination was poor for all the scores. Multivariable analysis identified pulse, connective tissue disease, PNI and potassium as independent predictors of severe morbidity. This model showed good discrimination and calibration. Internal validation using standard bootstrapping techniques confirmed the good performance. Nutrition could be an independent risk factor for major complications and a nutritional status coefficient could be included in current prognostic scores to improve risk estimation of major postoperative complications after oesophagectomy for cancer.

    Laparoscopic splenectomy is considered the gold standard for resecting normal-to-moderately bigger spleens in benign conditions, and in addition could be tried for patients with malignant splenic disorders. However, the safety of laparoscopic splenectomy in patients with hypersplenism is not well-known. This study aimed to investigate the efficacy and safety of laparoscopic splenectomy for patients with hypersplenism secondary to liver cirrhosis by comparing with the open splenectomy. Several databases were searched to identify comparative studies fulfilling the predefined selection criteria from January 2000 to June 2015. The subsequent key words were utilized for browsing "laparoscopy" or "laparoscopic", "open", "splenectomy", and "liver cirrhosis". Studies evaluating laparoscopic and open splenectomy for patients with liver cirrhosis were incorporated. Two evaluators personally strained the title and abstract of each publication. Citations with contemplated compliance within our eligibility criteria underwent compressed review. Meta-analysis was carried out according to the recommendations of the Cochrane Collaboration software (review manager 5.1). Seven studies containing 509 patients were included. Compared with the open splenectomy group, patients in the laparoscopic splenectomy group had significantly less intraoperative blood loss (MD=210.30; 95% CI: 11.28-409.32; P=0.04), longer operative time (MD=-31.58; 95% CI: -53.34--9.82; P=0.004), shorter duration of postoperative hospital stay (MD=3.41; 95% CI: 2.39-4.43; Psplenectomy.

    We have retrospectively reviewed the treatment results of postoperative radiotherapy (RT) for advanced oral cavity cancers. The purpose of this study was to determine the impact of anatomic subsite on the results of treatment. Between 1975 and 1985, 51 patients with squamous cell carcinoma of the oral tongue (OT = 29 patients) and floor of mouth (FOM = 22 patients) were treated with combined surgery plus RT. All had an indication(s) for RT including advanced primary disease (T3 or T4) (29 patients), close or positive margins (34 patients), and multiple positive neck nodes and/or extracapsular extension (41 patients). With a median follow-up of 6 years, the 5-year actuarial local control rate was 74% and the rate of distant metastasis (DM) was 34%. Despite the similar T stage, margin status and median RT dose, the 5-year actuarial local failure rate was 38% for OT vs. 11% for FOM (p = 0.03). Furthermore, the median survival after recurrence was 9 months for OT and 40 months for FOM (p = 0.02). At 5 years the determinate survival for both sites was (55%), and the likelihood of developing a second malignancy was 31%. The likelihood of developing DM was 50% for FOM (N0-N1 = 3 of 12, N2-N3 = 8 of 10) and 21% for OT (N0-N1 = 4 of 21, N2-N3 = 1 of 8). This study highlights significant differences between FOM and OT cancers in response to combined surgery and RT. Future strategies should be directed at the enhancement of local control for OT and better systemic therapy for those with advanced N-stage FOM

    Recent studies have revealed that Glasgow prognostic score (GPS), an inflammation-based prognostic score, is associated with poor outcome in a variety of tumors. However, few studies have investigated whether GPS measured prior to neoadjuvant chemoradiotherapy (nCRT) is useful for postoperative prognosis of patients with advanced esophageal squamous cell carcinoma (ESCC). GPS was calculated on the basis of admission data as follows: patients with both an elevated C-reactive protein (>10 mg/L) and hypoalbuminaemia (L) were allocated a GPS score of 2. Patients in whom only 1 of these biochemical abnormalities was present were allocated a GPS score of 1, and patients with a normal C-reactive protein and albumin were allocated a score of 0. All patients underwent radical en-bloc resection 3-4 weeks after nCRT. A total of 48 patients with clinical TNM stage II/III were enrolled. Univariate analyses revealed that there were significant differences in cancer-specific survival in relation to grade of response to nCRT (P = .004), lymph node status (P = .0065), lymphatic invasion (P = .0002), venous invasion (P = .0001), pathological TNM classification (P = .015), and GPS (P GPS classification showed a close relationship with lymphatic invasion, venous invasion, and number of lymph node (P = .0292, .0473, and .0485, respectively). GPS was found to be the only independent predictor of cancer-specific survival (odds ratio, 0.17; 95% confidence interval, 0.06-0.52; P = .0019). GPS, measured prior to nCRT, is an independent novel predictor of postoperative outcome in patients with advanced ESCC.

    2014-05-01

    The use of polypropylene mesh to augment surgery aimed to correct pelvic organ prolapse and stress urinary incontinence stems largely from the high recurrence rates of native tissue repairs. While objective outcomes were improved, mesh related complications began to emerge that included mesh exposures, extrusions, dyspareunia and other pain issues. However, the indication for and benefit of surgical intervention(s) to address these complications are lacking. We aim to review to current literature regarding postoperative pain outcomes following vaginal mesh revision. Evidence based literature indicates that mesh complications are not rare and surgery that aims to address them generally have an overall benefit. However, studies available are generally small case series of a retrospective nature with short follow up. Some themes are evident: there is a long lag period from mesh insertion to removal; there is a lack of a true denominator of total mesh insertions making it hard to gauge the real scope of the problem; mesh material found not along the expected trocar path or coursing close to neurovascular structures thus raises the possibility of technical errors during insertion. Transvaginal mesh revision(s) for mesh complications generally have a positive effect on pain outcomes, but better controlled studies are needed. Additionally, since technical issues may be a factor in the development of mesh complications, rigorous training and sufficient surgical case volume should be emphasized. © 2014 Wiley Publishing Asia Pty Ltd.

    Full Text Available Objective. Autologous fat injection laryngoplasty is ineffective for some patients with iatrogenic vocal fold paralysis, and additional laryngeal framework surgery is often required. An acoustically measurable outcome predictor for lipoinjection laryngoplasty would assist phonosurgeons in formulating treatment strategies. Methods. Seventeen thyroid surgery patients with unilateral vocal fold paralysis participated in this study. All subjects underwent lipoinjection laryngoplasty to treat postsurgery vocal hoarseness. After treatment, patients were assigned to success and failure groups on the basis of voice improvement. Linear prediction analysis was used to construct a new voice quality indicator, the number of irregular peaks (NIrrP. It compared with the measures used in the Multi-Dimensional Voice Program (MDVP, such as jitter (frequency perturbation and shimmer (perturbation of amplitude. Results. By comparing the [i] vowel produced by patients before the lipoinjection laryngoplasty (AUC = 0.98, 95% CI = 0.78–0.99, NIrrP was shown to be a more accurate predictor of long-term surgical outcomes than jitter (AUC = 0.73, 95% CI = 0.47–0.91 and shimmer (AUC = 0.63, 95% CI = 0.37–0.85, as identified by the receiver operating characteristic curve. Conclusions. NIrrP measured using the LP model could be a more accurate outcome predictor than the parameters used in the MDVP.

    There is much controversy regarding the effect of radiotherapy on facial nerve regeneration. However, the effect of brachytherapy has not been studied. Fifty-three patients underwent total parotidectomy of which 13 were radical with immediate facial nerve repair with sural nerve grafts. Six patients (group 1) did not receive adjuvant treatment whereas 7 patients (group 2) received postoperative brachytherapy plus radiotherapy. Functional outcomes were compared using Facial Clima. Mean percentage of blink recovery was 92.6 ± 4.2 for group 1 and 90.7 ± 5.2 for group 2 (p = .37). Mean percentage of commissural excursion restoration was 78.1 ± 3.5 for group 1 and 74.9 ± 5.9 for group 2 (p = .17). Mean time from surgery to first movement was 5.7 ± 0.9 months for group 1 and 6.3 ± 0.5 months for group 2 (p = .15). Brachytherapy plus radiotherapy does not affect the functional outcomes of immediate facial nerve repair with nerve grafts. Copyright © 2013 Wiley Periodicals, Inc.

    Pancreatic fistula (PF) remains the most challenging complication after pancreaticoduodenectomy (PD). The purpose of this study was to identify the risk factors of PF and delineate its impact on patient outcomes. We retrospectively reviewed clinical data of 532 patients who underwent PD and divided them into PF group and no PF group. Risk factors and outcomes of PF following PD were examined. PF was found in 65 (12.2%) cases, of whom 11 were classified into ISGPF grade A, 42 grade B, and 12 grade C. Clinically serious postoperative complications in the PF versus no PF group were mortality, abdominal bleeding, bile leak, intra-abdominal abscess and pneumonia. Univariate and multivariate analysis showed that blood loss ≥ 500 ml, pancreatic duct diameter ≤ 3 mm and pancreaticojejunostomy type were independent risk factors of PF after PD. Blood loss ≥ 500 ml, pancreatic duct diameter ≤ 3 mm and pancreatico-jejunostomy type were independent risk factors of PF after PD. PF was related with higher mortality rate, longer hospital stay, and other complications.

    Recent studies have revealed that the Glasgow prognostic score (GPS), an inflammation-based prognostic score, is useful for predicting outcome in a variety of cancers. This study sought to investigate the significance of GPS for prognostication of patients who underwent surgery with extrahepatic cholangiocarcinoma. We retrospectively analyzed a total of 62 patients who underwent resection for extrahepatic cholangiocarcinoma. We calculated the GPS as follows: patients with both an elevated C-reactive protein (>10 mg/L) and hypoalbuminemia (L) were allocated a score of 2; patients with one or none of these abnormalities were allocated a s ore of 1 or 0, respectively. Prognostic significance was analyzed by the log-rank test and a Cox proportional hazards model. Overall survival rate was 25.5 % at 5 years for all 62 patients. Venous invasion (p = 0.01), pathological primary tumor category (p = 0.013), lymph node metastasis category (p GPS (p = 0.008) were significantly associated with survival by univariate analysis. A Cox model demonstrated that increased GPS was an independent predictive factor with poor prognosis. The preoperative GPS is a useful predictor of postoperative outcome in patients with extrahepatic cholangiocarcinoma.

    Purpose: To analyze retrospectively the outcome of postoperative radiation therapy with or without concurrent chemotherapy for curatively resected stage II pancreatic cancer with T3 or N1 disease. Materials and Methods: Between January 1996 and December 2005, twenty-eight patients completed adjuvant radiation therapy at Ajou University Hospital. The patients had either pathologic T3 stage or N1 stage. The radiation target volume encompassed the initial tumor bed identified preoperatively, resection margin area and celiac nodal area. In the case of N1 patients, the radiation field extended to the lower margin of the L3 vertebra for covering both para-aortic lymph nodes bearing area. The median total radiation dose was 50 Gy. Ten patients received concurrent chemotherapy. Results: Thirteen patients (46%) showed loco-regional recurrences. The celiac axis nodal area was the most frequent site (4 patients). Five patients showed both loco-regional recurrence and a distant metastasis. Patients with positive lymph nodes had a relatively high probability of a distant metastasis (57.1%). Patients that had a positive resection margin showed a relatively high local failure rate (57.1%). The median disease-free survival period of all patients was 6 months and the 1- and 2-year disease free survival rates were 27.4% and 8.2%, respectively. The median overall survival period was 9 months. The 2- and 3-year overall survival rates were 31.6% and 15.8%, respectively. Conclusion: The pancreatic cancer patients with stage II had a high risk of local failure and a high risk of a distant metastasis. We suggest the concurrent use of an effective radiation-sensitizing chemotherapeutic drug and adjuvant chemotherapy after postoperative radiation therapy for the treatment of patients with stage II pancreatic cancer.

    To evaluate the visual acuity outcomes and to investigate the intraocular lens (IOL) and endocapsular ring positions with ultrasound biomicroscopy in 17 eyes of 10 patients with congenital lens subluxation who underwent the same surgical technique, by the same surgeon. The study was performed in the ''Hospital de Olhos de Pernambuco'' and ''Fundação Altino Ventura''. The surgical technique consisted of phacoaspiration with implant of endocapsular ring and intraocular lens with one loop haptic amputated. The age varied from 7 to 22 years. Data on visual acuity (VA) before and after surgery, surgery follow-up period, and complications were analyzed. All patients underwent ultrasound biomicroscopy. The mean follow-up period was 2.8 years. There was a VA improvement in 17 (100%) eyes: in 12 eyes (70.6%) the visual acuity was better than 20/40; 4 (23.5%) ranged from 20/40 to 20/100, and 1 (5.9%) had visual acuity worse than 20/100, however better than the preoperative visual acuity. The posterior capsular opacification occurred in 10 eyes (58.9%). Ultrasound biomicroscopy showed that all IOL were partially decentralized, however without surpassing the pupil border limit. Endocapsular ring position was correct and there was a good capsular support in all cases. The evaluated surgical treatment provided good intraocular lens and endocapsular ring position, with VA improvement Thus, this technique is a viable, effective and safe option for the visual rehabilitation of patients with congenital lens subluxation.

    The aim of this study is to evaluate the effect of depression, anxiety, and optimism on postoperative satisfaction and clinical outcomes in patients who underwent less than two-level posterior instrumented fusions for lumbar spinal stenosis and degenerative spondylolisthesis. Preoperative psychological status of subjects, such as depression, anxiety, and optimism, was evaluated using the Hospital Anxiety and Depression Scale (HADS) and the Revised Life Orientation Test (LOT-R). Clinical evaluation was determined by measuring changes in a visual analogue scale (VAS) and the Oswestry Disability Index (ODI) before and after surgery. Postoperative satisfaction of subjects assessed using the North American Spine Society lumbar spine questionnaire was comparatively analyzed against the preoperative psychological status. The correlation between patient's preoperative psychological status (depression, anxiety, and optimism) and clinical outcomes (VAS and ODI) was evaluated. VAS and ODI scores significantly decreased after surgery ( p optimism) was not related to the degree of improvement in clinical outcomes (VAS and ODI) after surgery. However, postoperative satisfaction was moderately correlated with optimism. Anxiety and optimism were more correlated with patient satisfaction than clinical outcomes. Accordingly, the surgeon can predict postoperative satisfaction of patients based on careful evaluation of psychological status before surgery.

    Lung transplantation for idiopathic pulmonary arterial hypertension has the highest reported postoperative mortality of all indications. Reasons lie in the complexity of treatment of these patients and the frequent occurrence of postoperative left ventricular failure. Transplantation on intraoperative extracorporeal membrane oxygenation support instead of cardiopulmonary bypass and even more the prolongation of extracorporeal membrane oxygenation into the postoperative period helps to overcome these problems. We reviewed our experience with this concept. All patients undergoing bilateral lung transplantation for idiopathic pulmonary arterial hypertension on intraoperative extracorporeal membrane oxygenation with or without prophylactic extracorporeal membrane oxygenation prolongation into the postoperative period between January 2000 and December 2014 were retrospectively analysed. Forty-one patients entered the study. Venoarterial extracorporeal membrane oxygenation support was prolonged into the postoperative period for a median of 2.5 days (range 1-40). Ninety-day, 1-, 3- and 5-year survival rates for the patient collective were 92.7%, 90.2%, 87.4% and 87.4%, respectively. When compared with 31 patients with idiopathic pulmonary arterial hypertension transplanted in the same period of time without prolongation of extracorporeal membrane oxygenation into the postoperative period, the results compared favourably (83.9%, 77.4%, 77.4%, and 77.4%; P = 0.189). Furthermore, these results are among the best results ever reported for this particularly difficult patient population. Bilateral lung transplantation for idiopathic pulmonary arterial hypertension with intraoperative venoarterial extracorporeal membrane oxygenation support seems to provide superior outcome compared with the results reported about the use of cardiopulmonary bypass. Prophylactic prolongation of venoarterial extracorporeal membrane oxygenation into the early postoperative period provides

    Gastric cancer is a major health problem, and frailty and sarcopenia will affect the postoperative outcomes in older people. However, there is still no systematic review to determine the role of frailty and sarcopenia in predicting postoperative outcomes among older patients with gastric cancer who undergo gastrectomy surgery. We searched Embase, Medline through the Ovid interface and PubMed websites to identify potential studies. All the search strategies were run on August 24, 2016. We searched the Google website for unpublished studies on June 1, 2017. The data related to the endpoints of gastrectomy surgery were extracted. Odds ratios (ORs) and their 95% confidence intervals (CIs) were pooled to estimate the association between sarcopenia and adverse postoperative outcomes by using Stata version 11.0. PRISMA guidelines for systematic reviews were followed. After screening 500 records, we identified eight studies, including three prospective cohort studies and five retrospective cohort studies. Only one study described frailty, and the remaining seven studies described sarcopenia. Frailty was statistically significant for predicting hospital mortality (OR 3.96; 95% CI: 1.12-14.09, P = 0.03). Sarcopenia was also associated with postoperative outcomes (pooled OR 3.12; 95% CI: 2.23-4.37). No significant heterogeneity was observed across these pooled studies (Chi 2  = 3.10, I 2  = 0%, P = 0.685). Sarcopenia and frailty seem to have significant adverse impacts on the occurrence of postoperative outcomes. Well-designed prospective cohort studies focusing on frailty and quality of life with a sufficient sample are needed.

    The accurate reconstruction of hip anatomy and biomechanics is thought to be important in achieveing good clinical outcomes following total hip arthroplasty (THA). To this end some newer hip designs have introduced further modularity into the design of the femoral component such that neck-shaft angle and anteversion, which can be adjusted intra-operatively. The clinical effect of this increased modularity is unknown. We have investigated the changes in these anatomical parameters following conventional THA with a prosthesis of predetermined neck-shaft angle and assessed the effect of changes in the hip anatomy on clinical outcomes. In total, 44 patients (mean age 65.3 years (standard deviation (SD) 7); 17 male/27 female; mean body mass index 26.9 (kg/m²) (SD 3.1)) underwent a pre- and post-operative three-dimensional CT scanning of the hip. The pre- and post-operative neck-shaft angle, offset, hip centre of rotation, femoral anteversion, and stem alignment were measured. Additionally, a functional assessment and pain score were evaluated before surgery and at one year post-operatively and related to the post-operative anatomical changes. The mean pre-operative neck-shaft angle was significantly increased by 2.8° from 128° (SD 6.2; 119° to 147°) to 131° (SD 2.1; 127° to 136°) (p = 0.009). The mean pre-operative anteversion was 24.9° (SD 8; 7.9 to 39.1) and reduced to 7.4° (SD 7.3; -11.6° to 25.9°) post-operatively (p shaft angles was found with a significant decrease of the post-operative anteversion and slight increase of the neck-shaft angles, but without any impact on clinical outcome. ©2015 The British Editorial Society of Bone & Joint Surgery.

    Review of a prospective database registry. To compare the Scoliosis Research Society (SRS)-22 and SRS-24 outcomes instruments in terms of scores, rate of ceiling effects, and discriminant ability in patients with pre- and postoperative adolescent idiopathic scoliosis. Despite improvements noted with the SRS-22, the SRS-24 is still occasionally used prospectively and for comparisons with previous studies reporting SRS-24 scores. Previous work has demonstrated that postoperative scores from the 2 versions are not interchangeable. A multicenter prospective registry of patients who underwent surgical correction of adolescent idiopathic scoliosis was queried for preoperative and 2-year postoperative SRS-22 and SRS-24 scores. Scores were compared between versions and ceiling effects were identified. Groups of deformity severity were created to evaluate discriminant ability. 829 patients were identified. The SRS-22 scores for pain and general function were significantly greater than SRS-24 scores (P self-image (P self-image domain was able to discriminate between large (29°+) and small (≤11°) residual curves (P < 0.05). Scores obtained by the SRS-22 and the SRS-24 are not translatable despite shared domains. Whereas both versions demonstrated preoperative discriminant ability, postoperative discrimination of residual deformity is lacking in both. Patient-reported outcomes of treatment are crucial in advancing treatment, and improvement in the ability to assess subjective outcomes is essential. 3.

    Tsungirirai is a counseling and information service developed during 1994 in response to the growing problem of HIV/AIDS in the small town of Norton, southwest of Harare, Zimbabwe. The objectives of the project include identification of key leaders in the area, determination of the setting in which HIV was spreading, and community consultation in program design and implementation. Tsungirirai's initial activities included a series of workshops on participatory techniques particularly the LADA (Listening-Appraisal-Dialogue-Action) method for key leaders, community men, women, and adolescents. Workshop participants demonstrated different views concerning HIV/AIDS problems. Key leaders viewed the HIV/AIDS problem within the context of existing laws that contradict traditional mores, while the youth linked the problem of HIV to the issue of unemployment and lack of recreation. Lessons learned include the following: 1) stop talking and listen; 2) start where people are at instead of telling them what they already know; 3) let the people decide; 4) turn a dream into reality; and 5) facilitate awareness process instead of leading it.

    Approximately 28% of the patients with cystic fibrosis are affected by cholelythiasis. More than 40% of them have a symptomatic disease, which would mandate cholecystectomy. The aim of this study was to review surgical and respiratory outcomes and quality of life scores of cystic fibrosis patients undergoing laparoscopic cholecystectomy for symptomatic cholelythiasis to verify the hypothesis that cholecystectomy is a low-risk operation by laparoscopy, not affecting unfavorably respiratory function and quality of life. Study group was consisted of 9 patients with a mean age of 24.8±8.1 years (range, 15 to 38 y), 2 male and 7 female patients, with cystic fibrosis and symptomatic cholelithiasis. Three patients also presented common bile duct stones. All the patients underwent perioperative Positive End-Expiratory Pressure mask sessions and aggressive antibiotic regimens. At the middle of the antibiotics regimen period, a standard laparoscopic cholecystectomy was performed. In the 3 cases with common duct lithiasis, the so-called "rendezvous" technique was carried out. Preoperatively, intraoperatively, and postoperatively, respiratory function was strictly monitored by the evaluation of SO2 and of the forced expiratory volume in 1 second (FEV1). Preoperatively and 6 months after laparoscopic cholecystectomy the Gastro Intestinal Quality of Life Index was evaluated on all patients. All the operations were completed laparoscopically. No mortality was observed. The intraoperative mean SO2 was 89.0%±5.6% (range, 80% to 95%), versus 82.8%±8.5% (range, 66% to 91%) at the extubation (P=0.006). Intraoperative respiratory functions were stable in 6 patients. In 3 patients, a severe bronchospasm occurred determining marked desaturation. Preoperative mean FEV1 was 70.5%±7.0% (range, 55% to 75%) versus 61.8%±13.2% (range, 39% to 80%) 48 hours after the operation (P=0.132). The 3 patients, who experienced intraoperatively severe bronchospasm, reported a 48 hours postoperative

    Robotic-assisted laparoscopic surgery is an emerging modality in the field of minimally invasive colorectal surgery. However, there is a dearth of data comparing outcomes with other minimally invasive techniques. We present a 3-arm (conventional, hand-assisted, and robotic) matched-case analysis of intraoperative and short-term outcomes in patients undergoing minimally invasive colorectal procedures. Between August 2008 and October 2009, 70 robotic cases of the rectum and rectosigmoid were performed. Thirty of these were organized into triplets with conventional and hand-assisted cases based on the following 6 matching criteria: 1) surgeon; 2) sex; 3) body mass index; 4) operative procedure; 5) pathology; and 6) history of neoadjuvant therapy in malignant cases. Demographics, intraoperative parameters, and postoperative outcomes were assessed. Pathological outcomes were analyzed in malignant cases. Data were stratified by postoperative diagnosis and operative procedure. There was no significant difference in intraoperative complications, estimated blood loss (126.1 ± 98.5 mL overall), or postoperative morbidity and mortality among the groups. Robotic technique required longer operative time compared with conventional laparoscopic (P hand-assisted (P robotic approach results in short-term outcomes comparable to conventional and hand-assisted laparoscopic approaches for benign and malignant diseases of the rectum and rectosigmoid. With 3-dimensional visualization, additional freedom of motion, and improved ergonomics, this enabling technology may play an important role when performing colorectal procedures involving the pelvic anatomy.

    This paper assesses the importance of community-level factors on prenatal care utilization in Zimbabwe. The analysis is performed using data from the two most recent rounds of the nationally representative Demographic and Health Survey for Zimbabwe conducted in 2005/06 and 2010/11 linked with other community-level data. We use logistic, generalized linear regressions as well as multilevel mixed models to examine the factors associated with the frequency, timing and quality of prenatal care. Our results suggest that contraceptive prevalence, religious composition, density of nurses, health expenditures per capita and availability of government hospitals in communities are important predictors of prenatal care use in Zimbabwe. These findings have important implications for public health policy in Zimbabwe - a country with unfavorable maternal and child health outcomes. Copyright © 2017 Ministry of Health, Saudi Arabia.

    We analysed the gross motor recovery of infants and toddlers with cyanotic and acyanotic congenital heart disease (CHD) who received early postoperative physical therapy to see whether there was any difference in the duration to recovery. This study retrospectively evaluated the influence of early physical therapy on postoperative gross motor outcomes of patients with CHD. The gross motor ability of patients with cyanotic (n = 25, average age: 376.4 days) and acyanotic (n = 26, average age: 164.5 days) CHD was evaluated using our newly developed nine-grade mobility assessment scale. Physical therapy was started at an average of five days after surgery, during which each patient's gross motor ability was significantly decreased compared with the preoperative level. Patients (who received early postoperative physical therapy) with cyanotic (88.0%) and acyanotic CHD (96.2%) showed improved preoperative mobility grades by the time of hospital discharge. However, patients with cyanotic CHD had a significantly prolonged recovery period compared to those with acyanotic CHD (p congenital heart disease are likely at greater risk of gross motor delays and have a prolonged recovery period of gross motor ability compared to those with acyanotic congenital heart disease. Early postoperative physical therapy for patients with congenital heart disease after cardiac surgery promoted gross motor recovery. The postoperative recovery period to preoperative mobility grade was affected by pre-, intra-, and postoperative factors. Rehabilitation experts should consider the risk of gross motor delays of patients with congenital heart disease after cardiac surgery and the early postoperative physical therapy to promote their gross motor recovery.

    Bariatric surgery patients are at high risk of perioperative respiratory adverse events. We hypothesized that the use of sugammadex to reverse neuromuscular blockade could improve postoperative respiratory outcomes. Prospective observational series of consecutive patients scheduled for laparoscopic bariatric surgery in whom neuromuscular blockade was reverted with sugammadex were compared with a historical matched cohort of patients reverted with neostigmines. The necessity of postoperative mechanical ventilation or pathological changes in postoperative chest X-ray were two of the comparisons done. We enrolled 160 patients in each group (Sugammadex - SG and Historical - HG). Two patients (mean, CI 95%), (1.25, 0.34-4.4) in the SG and five patients in the HG (mean, CI 95%), (3.13, 1.34-7.11) required mechanical ventilation immediately after surgery (p=0.38, chi-square test). Significantly less chest X-ray postoperative changes were observed in the SG: 11 patients (6.9%) versus 26 patients (16.3%) in the HG (Odds ratio OR, CI 95%) (0.36, 0.18-0.8). Requirement of mechanical ventilation is not associated to the reversal agent employed. Less pathological postoperative chest X-ray changes were found in the group of patients whose neuromuscular blockade was reverted with sugammadex.

    To evaluate the effects of urinary bladder retroflexion (UBR) and surgical technique on postoperative complication rates and long-term outcome in dogs with perineal hernia. Retrospective case series. 41 client-owned dogs with perineal hernia that underwent surgery between November 2002 and November 2009. Medical records were reviewed for information on dog signalment, history, physical examination findings, ultrasonographic findings, surgical techniques, intraoperative complications, duration of hospital stay, postoperative complications, and long-term outcome. 31 dogs had no UBR, and 10 dogs had UBR. Internal obturator muscle transposition (IOMT) was performed in 20 dogs, and a cystopexy or colopexy was performed before the IOMT (LapIOMT) in 21. Postoperative complications included tenesmus (n = 8) and urinary incontinence (1). Rates of postoperative complications were not significantly different between the no-UBR and UBR groups or between the IOMT and LapIOMT groups. Thirty-two dogs were free of clinical signs at the time of the study. The median disease-free interval did not differ significantly between dogs in the no-UBR and UBR groups, but it was significantly lower in the LapIOMT group than in the IOMT group. None of the 7 dogs with UBR that were treated without cystopexy developed recurrence of UBR. UBR was not associated with an increased rate of postoperative complications relative to no UBR and had no effect on the long-term outcome in dogs with perineal hernia. The use of IOMT alone may be recommended for clinical use because LapIOMT offered no clear advantage.

    Full Text Available Surgically managed burn patients admitted between 2010-14 were included. Operative stay was defined as the time from admission until the last operation, postoperative stay as the time from the last operation until discharge. The difference in variation was analysed with F-test. A retrospective review of medical records was done to explore reasons for extended postoperative stay. Multivariable regression was used to assess factors associated with operative stay and postoperative stay.Operative stay/TBSA% showed less variation than total duration/TBSA% (F test = 2.38, p<0.01. The size of the burn, and the number of operations, were the independent factors that influenced operative stay (R2 0.65. Except for the size of the burn other factors were associated with duration of postoperative stay: wound related, psychological and other medical causes, advanced medical support, and accommodation arrangements before discharge, of which the two last were the most important with an increase of (mean 12 and 17 days (p<0.001, R2 0.51.Adjusted operative stay showed less variation than total hospital stay and thus can be considered a more accurate outcome measure for surgically managed burns. The size of burn and number of operations are the factors affecting this outcome measure.

    This study evaluates long-term outcomes of two trabecular micro-bypass stents, one suprachoroidal stent, and postoperative prostaglandin in eyes with refractory open angle glaucoma (OAG). Prospective ongoing 5-year study of 80 eligible subjects (70 with 4-year follow-up) with OAG and IOP ≥ 18 mmHg after prior trabeculectomy and while taking 1-3 glaucoma medications. Subjects received two iStent ® trabecular micro-bypass stents, one iStent Supra ® suprachoroidal stent, and postoperative travoprost. Postoperative IOP was measured with medication and annually following medication washouts. Performance was measured by the proportion of eyes with ≥ 20% IOP reduction on one medication (the protocol-specified prostaglandin) versus preoperative medicated IOP (primary outcome); and the proportion of eyes with postoperative IOP ≤ 15 and ≤ 18 mmHg on one medication (secondary outcome). Additional clinical and safety data included medications, visual field, pachymetry, gonioscopy, adverse events, visual acuity, and slit-lamp and fundus examinations. Preoperatively, mean medicated IOP was 22.0 ± 3.1 mmHg on 1.2 ± 0.4 medications, and mean unmedicated IOP was 26.4 ± 2.4 mmHg. Postoperatively, among eyes without later cataract surgery, mean medicated IOP at all visits through 48 months was ≤ 13.7 mmHg (≥ 37% reduction), and annual unmedicated IOP was ≤ 18.4 mmHg (reductions of ≥ 30% vs. preoperative unmedicated IOP and ≥ 16% vs. preoperative medicated IOP). At all postoperative visits among eyes without additional surgery or medication, ≥ 91% of eyes had ≥ 20% IOP reduction on one medication versus preoperative medicated IOP. At month 48, 97 and 98% of eyes achieved IOP ≤ 15 and ≤ 18 mmHg, respectively, on one medication. Six eyes required additional medication, no eyes required additional glaucoma surgery, and safety measurements were favorable throughout follow-up. IOP control was achieved safely with two

    To analyze factors associated with metastases, prostate cancer-specific mortality, and all-cause mortality in pN1 patients. We analyzed 3,642 radical prostatectomy patients within the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Pathologic Gleason grade, number of lymph nodes (LN) removed, and first postoperative prostate-specific antigen (PSA) (PSA. Of 3,642 patients, 124 (3.4%) had pN1. There were 71 (60%) patients with 1 positive LN, 32 (27%) with 2 positive LNs, and 15 (13%) with ≥3. Among men with pN1, first postoperative PSA wasPSA ≥0.2 ng/ml (P = 0.005) were associated with metastases. First postoperative PSA ≥0.2ng/ml was associated with metastasis on multivariable analysis (P = 0.046). Log-rank analysis revealed a more favorable metastases-free survival in patients with a first postoperative PSAPSAPSA ≥0.2ng/ml were more likely to develop metastases. First postoperative PSA may be useful in identifying pN1 patients who harbor distant disease and aid in secondary treatment decisions. Copyright © 2018 Elsevier Inc. All rights reserved.

    Preserving functionality is of significant importance during neurosurgical resection of brain tumors. Specialized centers also map further brain functions apart from motor and language functions, such as arithmetic processing (AP). The mapping of AP by navigated repetitive transcranial magnetic stimulation (nrTMS) in healthy volunteers has been demonstrated. The present study aimed to correlate the results of mapping AP with functional patient outcomes. We included 26 patients with parietal brain tumors. Due to preoperative impairment of AP, mapping was not possible in 8 patients (31%). We stimulated 52 cortical sites by nrTMS while patients performed a calculation task. Pre- and postoperatively, patients underwent a standardized number-processing and calculation test (NPCT). Tumor resection was blinded to nrTMS results, and the change in NPCT performance was correlated to resected AP-positive spots as identified by nrTMS. The resection of AP-positive sites correlated with a worsening of the postoperative NPCT result in 12 cases. In 3 cases, no AP-positive sites were resected and the postoperative NPCT result was similar to or better than preoperatively. Also, in 3 cases, the postoperative NPCT result was better than preoperatively, although AP-positive sites were resected. Despite only presenting a low number of cases, nrTMS might be a useful tool for preoperative mapping of AP. However, the reliability of the present results has to be evaluated in a larger series and by intraoperative mapping data. Copyright © 2018 Elsevier Inc. All rights reserved.

    The predictive value of changes in intraoperatively acquired motor-evoked potentials (MEPs) of the lower cranial nerves (LCN) IX-X (glossopharyngeal-vagus nerve) and CN XII (hypoglossal nerve) on operative outcomes was investigated. MEPs of CN IX-X and CN XII were recorded intraoperatively in 63 patients undergoing surgery of the posterior cranial fossa. We correlated the changes of the MEPs with postoperative nerve function. For CN IX-X, we found a correlation between the amplitude of the MEP ratio and uvula deviation (P = 0.028) and the amplitude duration of the MEP and gag reflex function (P = 0.027). Patients with an MEP ratio of the glossopharyngeal-vagus amplitude ≤1.47 μV had a 3.4 times increased risk of developing a uvula deviation. Patients with a final MEP duration of the CN IX-X ≤11.6 milliseconds had a 3.6 times increased risk for their gag reflex to become extinct. Our study greatly contributes to the current knowledge of intraoperative MEPs as a predictor for postoperative cranial nerve function. We were able to extent previous findings on MEP values of the facial nerve on postoperative nerve function to 3 additional cranial nerves. Finding reliable predictors for postoperative nerve function is of great importance to the overall quality of life for a patient undergoing surgery of the posterior cranial fossa.

    Approximately thirty percent of the global burden of disease is comprised of surgical conditions. However, five billion people lack access to surgery, with complex factors acting as barriers. We examined whether patient demographics predict barriers to care, and the relation between these factors and postoperative complications in a prospective cohort. Participants included people presenting to a global charity in Republic of Congo with a surgical condition between August 2013 and May 2014. The outcomes were self-reported barrier to care and postoperative complications documented by medical record. Logistic regression was used to adjust for covariates. Of 1237 patients in our study, 1190 (96.2 %) experienced a barrier to care and 126 (10.2 %) experienced a postoperative complication. The most frequently reported barrier was cost (73 %), followed by lack of provider (8.2 %). Greater wealth was associated with decreased odds of cost as a barrier (OR 0.72 [0.57, 0.90]). Greater wealth (OR 1.52 [1.03, 2.25]) and rural home location (OR 3.35 [1.16, 9.62]) were associated with increased odds of no surgeon being available. Cost as a barrier (OR 2.82 [1.02, 7.77]), female sex (OR 3.45 [1.62, 7.33]), and lack of surgeon (OR 5.62 [1.68, 18.77]) were associated with increased odds of postoperative complication. Patient wealth was not associated with odds of postoperative complication. Barriers to surgery were common in Republic of Congo. Patient wealth and home location may predict barriers to surgery. Addressing gender disparities, access to providers, and patient perception of barriers in addition to removal of barriers may help maximize patient health benefits.

  1. Overpopulation and unemployment in Zimbabwe.

    1996-02-01

    The size of Zimbabwe's African population has grown dramatically over the past 50 years, with 5.7 children on average being born per woman. The following factors are responsible for the rapid population growth in Zimbabwe: the country's economic prosperity during the period of the Central African Federation from 1953 to 1963, and its successful food policy before and after independence; the success of the health system, also in both periods; and the fact that women have not been incorporated into the economy as wage-earners. A brief historical overview is presented, followed by sections on the food policy and health system, reasons for the persistence of large families, and the relationship between wage-earning by women and the birth rate. The author also describes some of the problems caused by overpopulation. Engaging more women in regular wage-earning employment is the key to controlling the birth rate in Zimbabwe. Current government policies encouraging female employment in government services and the economy in general, along with the expansion of contraceptive services, could influence female fertility over the long term.

    Although child sexual abuse is a significant public health problem globally, its incidence, prevention, and management is less well described in resource-poor settings. In poorer settings prevention initiatives assume even more importance since resources for managing abused children are severely limited. This article examines the current status of policy and practice related to the prevention of child sexual abuse in Zimbabwe. It identifies implementation challenges and highlights opportunities that could be embraced to reduce CSA in Zimbabwe, based on evidence synthesized from recent work. Although Zimbabwe has a well-established legal and regulatory framework to protect children from child sexual abuse, implementation of existing policies is weak. Financial, human, and material resource constraints are frequently cited to explain limited prevention activity. Effective strategies for the prevention of child sexual abuse should focus on implementing existing legislation, targeting schoolchildren, and getting community involvement. A dedicated budget would help entrench these strategies, but gains can be achieved even in the absence of this.

    Full Text Available Introduction. The aim of this study is to examine the feasibility of reducing postoperative hospital stay following open partial nephrectomy through the implementation of a goal directed clinical management pathway. Materials and Methods. A fast track clinical pathway for open partial nephrectomy was introduced in July 2006 at our institution. The pathway has daily goals and targets discharge for all patients on the 3rd postoperative day (POD. Defined goals are (1 ambulation and liquid diet on the evening of the operative day; (2 out of bed (OOB at least 4 times on POD 1; (3 removal of Foley catheter on the morning of POD 2; (4 removal of Jackson Pratt drain on the afternoon of POD 2; (4 discharge to home on POD 3. Patients and family are instructed in the fast track protocol preoperatively. Demographic data, tumor size, length of stay, and complications were captured in a prospective database, and compared to a control group managed consecutively immediately preceding the institution of the fast track clinical pathway. Results. Data on 33 consecutive patients managed on the fast track clinical pathway was compared to that of 25 control patients. Twenty two (61% out of 36 fast track patients and 4 (16% out of 25 control patients achieved discharge on POD 3. Overall, fast track patients had a shorter hospital stay than controls (median, 3 versus 4 days; P = .012. Age (median, 55 versus 57 years, tumor size (median, 2.5 versus 2.5 cm, readmission within 30 days (5.5% versus 5.1%, and complications (10.2% versus 13.8% were similar in the fast track patients and control, respectively. Conclusions. In the present series, a fast track clinical pathway after open partial nephrectomy reduced the postoperative length of hospital stay and did not appear to increase the postoperative complication rate.

    To examine correlation between postoperative radiographic and cosmetic improvements in Lenke 1C adolescent idiopathic scoliosis (AIS) with patients' self-rated outcomes of health and disability at follow-up as determined by the Scoliosis Research Society questionnaire (SRS-30), Oswestry Disability Index score (ODI) and measure of overall health quality Euroqol-5d (EQ-5D). 24 Lenke 1C scoliosis patients, mean age 16.5 (12.8-38.1) years, treated with posterior pedicle screw-only construct, were included. The coronal profile indices (radiographic and cosmetic) regarding magnitude of spinal deformity and truncal balance were measured preoperatively, postoperatively and at final follow-up. A comprehensive index of overall back symmetry was also measured by means of the Posterior Trunk Symmetry Index (POTSI). Pearson's correlation analysis determined the association between the radiographic-cosmetic indices and patient-rated outcomes. Mean follow-up for the cohort was 4.4 (±1.86) years. The thoracic apical vertebra-first thoracic vertebra horizontal distance (AV-TI) correction had significant correlation with function, self-image, and mental health SRS-30 scores (0.55, 0.54, 0.66). Similarly, thoracic apical vertebra horizontal translation from central sacral vertical line (AV-CSVL) correction at follow-up had significant correlation with self-image and management domains (0.57, 0.50). Follow-up POTSI correlated well with SRS-30 and EQ-5D scores (r = -0.64, -0.54). Postoperative leftward trunk shift/spinal imbalance did not influence overall cosmesis and outcomes; significant spinal realignment was evident in follow-up resulting in physiological balance and acceptable cosmesis and outcomes. Significant, but less than "perfect" correlations were observed between the radiographic, cosmetic measures and patient-rated outcomes. Thoracic AV-CSVL, AV-T1 correction and POTSI associated significantly with SRS-30 scores. Whereas, thoracic Cobb angle, Cobb correction, and

    Knee osteoarthritis (OA) is a leading cause of disability in older adults (≥60) in the UK. If nonsurgical management fails and if OA severity becomes too great, knee arthroplasty is a preferred treatment choice. Preoperative physiotherapy is often offered as part of rehabilitation to improve postoperative patient-based outcomes. Systematically review whether preoperative physiotherapy improves postoperative, patient-based outcomes in older adults who have undergone total knee arthroplasty (TKA) and compare study interventions to best-practice guidelines. A literature search of Randomized Controlled Trials (RCTs), published April 2004-April 2014, was performed across six databases. Individual studies were evaluated for quality using the PEDro Scale. Ten RCTs met the full inclusion/exclusion criteria. RCTs compared control groups versus: preoperative exercise (n = 5); combined exercise and education (n = 2); combined exercise and acupuncture (n = 1); neuromuscular electrical stimulation (NMES; n = 1); and acupuncture versus exercise (n = 1). RCTs recorded many patient-based outcomes including knee strength, ambulation, and pain. Minimal evidence is presented that preoperative physiotherapy is more effective than no physiotherapy or usual care. PEDro Scale and critical appraisal highlighted substantial methodological quality issues within the RCTs. There is insufficient quality evidence to support the efficacy of preoperative physiotherapy in older adults who undergo total knee arthroplasty.

    Transsphenoidal surgery is the treatment of choice for ACTH-producing pituitary adenoma (Cushing's disease) and pituitary irradiation is widely considered the most appropriate treatment for patients with Cushing's disease for whom transsphenoidal surgery has been unsuccessful. We studied 49 consecutive patients who underwent transsphenoidal surgery for the treatment of Cushing's disease at Tokyo Women's Medical University from 1977-1997 with a mean follow-up duration of 87.6 months (range, 24-253 months). We examined the relationship between postoperative endocrinological data, assessed between 3 and 8 weeks after surgery, and long-term outcome and efficacy of pituitary irradiation after surgery. Long-term remission was defined as the regression of the symptom and signs of Cushing's syndrome, and restoration of normal levels of plasma ACTH, cortisol and urinary free cortisol, together with adequate suppression of morning plasma cortisol levels following the administration of low dose (1 mg) of dexamethasone. Thirty patients had no additional treatment after pituitary surgery. Only 1 of 25 patients (4%) whose postoperative plasma cortisol level was less than 2 μg/dl developed recurrent disease whereas 3 out of 5 patients with postoperative plasma cortisol levels higher than 2 μg/dl relapsed. Postoperative external pituitary radiation was used to treat the remaining 19 patients. Four patients who received radiation therapy had a low or undetectable postoperative plasma cortisol level (<2 μg/dl, 56 nmol/L) and all of these patients developed hypopituitarism whereas 5 patients with subnormal plasma cortisol levels (2.0-10.0 μg/dl) remained in remission. Among 10 patients with persistent disease after surgery, 6 entered remission 6-47 months after irradiation but one of them subsequently relapsed after 108 months. These results suggest that additional therapy should be avoided in patients with a postoperative plasma cortisol less than 2 μg/dl because relapse is

  8. Electricity from bagasse in Zimbabwe

    2003-01-01

    Zimbabwe has suffered electrical power shortages resulting in electrical energy imports rising to between 40% and 50% of total energy needs. Electricity generation capacity has stagnated at around 2000 Megawatts (MW e ) since 1985, when two thermal units totaling 440 MW e were completed at Hwange. The effective capacity is 1.75 GW e . The current plan is to increase capacity by installing 600 MW e at Hwange at a cost of at least US $ 600 million. Raising this level of capital is difficult hence over the last 15 years there has been a failure to increase capacity. This article is based on a study of bagasse cogeneration in Zimbabwe and Mauritius conducted over a two-year period. It discusses technology improvements that can be made in the sugar sector to improve process and energy efficiency for the purposes of becoming an independent power producer that supplies power to the grid continuously throughout the year. Power plant investment in the sugar industry offers a bridging and realizable alternative for electricity generation in Zimbabwe. Investment in a 35 MW e bagasse (moisturized fiber left when sugar has been extracted from sugarcane) system would require a capital of about US$ 35 million using modern technology based on experiences in Mauritius and Reunion. A technical and economic evaluation and analysis reveals that bagasse power development is technically and economically feasible if electricity is priced at the long-term marginal cost. At current import prices, financial assistance from the global environment facility and/or the clean development mechanism of the Kyoto protocol would be necessary. The solving of the current political and economic problems in the country would pave the way for attracting a technical partner and development, of bagasse power using domestic and international financing

    N-terminal pro-B-type natriuretic peptide (NT-proBNP) predicts adverse cardiac outcome in patients undergoing vascular surgery. However, several conditions might influence this prognostic value, including anemia. In this study, we evaluated whether anemia confounds the prognostic value of NT-proBNP for predicting cardiac events in patients undergoing vascular surgery. A detailed cardiac history, resting echocardiography, and hemoglobin and NT-proBNP levels were obtained in 666 patients before vascular surgery. Anemia was defined as serum hemoglobin value of NT-proBNP for the prediction of the composite end point. Multivariable regression analysis was used to assess the additional value of NT-proBNP for the prediction of postoperative cardiac events in nonanemic and anemic patients. Anemia was present in 206 patients (31%) before surgery. Hemoglobin level was inversely related with the NT-proBNP levels (beta coefficient = -2.242; P = 0.025). The optimal predictive cutoff value of NT-proBNP for predicting the composite cardiovascular outcome was 350 pg/mL. After adjustment for clinical cardiac risk factors, both anemia (odds ratio [OR] 1.53; 95% confidence interval [CI]: 1.07-2.99) and increased levels of NT-proBNP (OR 4.09; 95% CI: 2.19-7.64) remained independent predictors for postoperative cardiac events. However, increased levels of NT-proBNP were not predictive for the risk of adverse cardiac events in the subgroup of anemic patients (OR 2.16; 95% CI: 0.90-5.21). Both anemia and NT-proBNP are independently associated with an increased risk for postoperative cardiac events in patients undergoing vascular surgery. NT-proBNP has less predictive value in anemic patients.

    Background and purpose: The role of post-operative radiotherapy in patients with resected non-small-cell lung cancer (NSCLC) is unclear. Modifiable factors, like smoking, may help guide therapy. We retrospectively evaluated the impact of smoking on control in patients undergoing post-operative radiation therapy (PORT) for NSCLC. Materials and methods: Between 1995 and 2007, 152 patients who underwent surgery for NSCLC were analyzed (median follow-up 26 months). Non-smokers were defined as patients who never smoked or who had stopped smoking at the time of initial consultation. Sixty seven percent were non-smokers; 5% never smoked, 40% of the non-smokers had ceased smoking for a year or less, while 55% had stopped for more than a year. Results: On univariate analysis, smokers had worse 5-year local control than non-smokers (70% versus 90%, p = 0.001) and locoregional control (52% versus 77%, p = 0.002). The 5 -year survival rate was 21% for smokers and 31% for non-smokers (p = 0.2). On multivariate analysis, smokers maintained a detrimental effect on locoregional control (HR 3.6, p = 0.0006). Conclusions: Smokers at initial consultation have poorer local and locoregional control after PORT than non-smokers. In patients being considered for PORT for NSCLC, quitting smoking before treatment confers additional treatment advantage.

    Anatomic techniques of ankle ligament repair have the advantage of restoring the anatomy and kinematics of the joint. This study presents a technique for anatomic reconstruction of the lateral ligament complex by way of lateral ligament advancement using suture anchors associated with immediate protected full weightbearing; 2- to 5-year clinical outcomes are reported. This technique of providing an anatomic reconstruction with a secure fixation will enable early rehabilitation with immediate, protected weightbearing, with favorable outcomes. Case series; Level of evidence, 4. Fifty-five patients with chronic lateral ankle instability who failed nonoperative management underwent modified Broström repair (lateral ligament fibular advancement) between 2005 and 2008. The anterior talofibular ligament and calcaneofibular ligament were released from the fibula and advanced using 2 double-loaded metallic suture anchors (3.5 mm). Full weightbearing in a walking boot was allowed from the first postoperative day. Patients were assessed preoperatively and at a minimum 2-year follow-up using the Foot and Ankle Outcome Score. Complication, failure (recurrent instability), and return-to-sport rates were also recorded. Six patients (11%) were lost to follow-up, leaving a study group of 49 patients (23 men, 26 women). The mean age at the time of surgery was 25 years (range, 18-37 years), with a mean duration of symptoms of 1.8 years (range, 6 months to 5 years). The mean follow-up time was 42 months (range, 24-60 months). Significant improvement was seen in the Foot and Ankle Outcome Score from preoperatively to postoperatively (from 36 to 75.4, P ankle-related quality of life subscale from 35 to 78 (P anchor fixation is an effective procedure for the treatment of chronic lateral ankle instability and allows immediate weightbearing. © 2014 The Author(s).

    The aim of the study was to analyze epidemiologic parameters, treatment-related data and prognostic factors in the management of gastric cancer patients of a university surgical center under conditions of routine clinical care before the onset of the era of multimodal therapies. By analyzing our data in relation with multi-center quality assurance trials [German Gastric Cancer Study - GGCS (1992) and East German Gastric Cancer Study - EGGCS (2004)] we aimed at providing an instrument of internal quality control at our institution as well as a base for comparison with future analyses taking into account the implementation of evolving (multimodal) therapies and their influence on treatment results. Retrospective analysis of prospectively gathered data of gastric cancer patients treated at a single institution during a defined 10-year time period with multivariate analysis of risk factors for early postoperative outcome. From 04/01/1993 through 03/31/2003, a total of 328 gastric cancer patients were treated. In comparison with the EGGCS cohort there was a larger proportion of patients with locally advanced and proximally located tumors. 272 patients (82.9%) underwent surgery with curative intent; in 88.4% of these an R0 resection was achieved (EGGCS/GGCS: 82.5%/71.5%). 68.2% of patients underwent preoperative endoluminal ultrasound (EUS) (EGGCS: 27.4%); the proportion of patients undergoing EUS increased over the study period. Diagnostic accuracy of EUS for T stage was 50.6% (EGGCS: 42.6%). 77.2% of operated patients with curative intent underwent gastrectomy (EGGCS/GGCS: 79.8%/71.1%). Anastomotic leaks at the esophagojejunostomy occurred slightly more frequently (8.8%) than in the EGGCS (5.9%) and GGCS (7.2%); however, postoperative morbidity (36.1%) and early postoperative mortality (5.3%) were not increased compared to the multi-center quality assurance study results (EGGCS morbidity, 45%); EGGCS/GGCS mortality, 8%/8.9%). D2 lymphadenectomy was performed in 72

    NSQIP Risk Calculator was developed to allow surgeons to inform their patients about their individual risks for surgery. Its ability to predict complication rates and length of stay (LOS) has made it an appealing tool for both patients and surgeons. However, the NSQIP Risk Calculator has been criticized for its generality and lack of detail towards surgical subspecialties, including the hepatopancreaticobiliary (HPB) surgery. We wish to determine whether the NSQIP Risk Calculator is predictive of post-operative complications and LOS with respect to Whipple's resections for our patient population. As well, we wish to identify strategies to optimize early surgical outcomes in patients with pancreatic cancer. We conducted a retrospective review of patients who underwent elective Whipple's procedure for benign or malignant pancreatic head lesions at Health Sciences North (Sudbury, Ontario), a tertiary care center, from February 2014 to August 2016. Comparisons of LOS and post-operative complications between NSQIP-predicted and actual ones were carried out. NSQIP-predicted complications rates were obtained using the NSQIP Risk Calculator through pre-defined preoperative risk factors. Clinical outcomes examined, at 30 days post-operation, included pneumonia, cardiac events, surgical site infection (SSI), urinary tract infection (UTI), venous thromboembolism (VTE), renal failure, readmission, and reoperation for procedural complications. As well, mortality, disposition to nursing or rehabilitation facilities, and LOS were assessed. A total of 40 patients underwent Whipple's procedure at our center from February 2014 to August 2016. The average age was 68 (50-85), and there were 22 males and 18 females. The majority of patients had independent baseline functional status (39/40) with minimal pre-operative comorbidities. The overall post-operative morbidity was 47.5% (19/40). The rate of serious complication was 17.5% with four Clavien grade II, two grade III, and one grade

    Sub-analysis of the prospective AOSpine CSM North America and International studies. The aim of this study was to investigate the impact of cervical spine deformity on pre- and postoperative outcomes in fusion surgeries for degenerative cervical myelopathy. The associations between cervical alignment and patient outcomes have been reported but are not well established in a myelopathy cohort. The impact of deformity correction in this population also needs to be elucidated. A total of 757 patients were enrolled in two prospective international multicenter AOSpine studies. Among those who underwent anterior or posterior fusion surgeries, pre- and 1-year postoperative upright neutral lateral radiographs of cervical spine were investigated to measure C2-7 Cobb angle and C2-7 sagittal vertical axis (SVA). Patient outcome measures included the modified Japanese Orthopedic Association score for myelopathy severity, Neck Disability Index (NDI), and Short-form 36 (SF-36). These scores were compared between patients with and without cervical deformity, which was defined as C2-7 Cobb >10° kyphosis and/or SVA >40 mm. A total of 178 patients were included with complete pre- and postoperative radiographs. SVA significantly increased postoperatively (27.4 vs. 30.7 mm, P = 0.004). All outcome measurement showed significant improvements above minimal clinically important differences. 23.6% of the patients had cervical deformity preoperatively; preoperative deformity was associated with worse preoperative NDI scores (45.7 vs. 38.9, P = 0.04). Postoperatively, those with deformity exhibited significantly lower SF-36 physical component scores (37.2 vs. 41.4, P = 0.048). However, when focusing on the preoperatively deformed cohort, we did not find any significant differences in the postoperative outcome scores between those with and without residual deformity. There was a significant association between cervical deformity and both preoperative disease severity and

    Endoscopic third ventriculostomy (ETV) is increasingly being used as an alternative treatment for post-tuberculous meningitis (TBM) hydrocephalus. The aim of this study was to affirm the role of ETV in patients with TBM hydrocephalus and also to study the usefulness of cine phase-contrast MR imaging (cine MR imaging) for functional assessment of the ETV stoma. An additional goal was to identify factors that influence the outcome of ETV, so as to define patients with TBM hydrocephalus in whom ETV is warranted. Twenty-six patients with TBM hydrocephalus treated with ETV were evaluated clinically and with cine MR imaging postoperatively. The duration of follow-up ranged from 1 to 15 months. The authors evaluated flow void changes in the floor of the third ventricle and analyzed parameters from the preoperative data, which they then used as a basis for comparison between endoscopically successful and endoscopically unsuccessful cases. The overall success rate of ETV in TBM hydrocephalus was 73.1% in this case series. Cine MR imaging showed a sensitivity of 94.73% and specificity of 71.42% for the functional assessment of third ventriculostomy in these patients, with the efficacy being maintained during follow-up. The outcome of ETV showed a statistically significant correlation with the stage of illness and presence of intraoperative cisternal exudates. Although duration of symptoms and duration of preoperative antituberculous therapy (ATT) appeared to influence the outcome, their correlation with outcome was not statistically significant. Endoscopic third ventriculostomy should be considered as the first surgical option for CSF diversion (that is, before shunt surgery) in patients with TBM hydrocephalus. Cine MR imaging is a highly effective noninvasive tool for the postoperative functional assessment of stomata. Patients who presented with a history of longer duration and those who were administered preoperative ATT for a longer period had a better outcome of

    Modern total hip arthroplasty is largely dependent on the successful preservation of hip geometry. Thus, a successful implementation of the preoperative planning is of great importance. The present study evaluates the accuracy of anatomic hip reconstruction predicted by 2D digital planning using a calcar-guided short stem of the newest generation. A calcar-guided short stem was implanted in 109 patients in combination with a cementless cup using the modified anterolateral approach. Preoperative digital planning was performed including implant size, caput-collum-diaphyseal angle, offset, and leg length using mediCAD II software. A coordinate system and individual scale factors were implemented. Postoperative outcome was evaluated accordingly and was compared to the planning. Intraoperatively used stem sizes were within one unit of the planned stem sizes. The postoperative stem alignment showed a minor and insignificant (p = 0.159) mean valgization of 0.5° (SD 3.79°) compared to the planned caput-collum-diaphyseal angles. Compared to the planning, mean femoral offset gained 2.18 (SD 4.24) mm, while acetabular offset was reduced by 0.78 (SD 4.36) mm during implantation resulting in an increased global offset of 1.40 (SD 5.51) mm (p = 0.0094). Postoperative femoroacetabular height increased by a mean of 5.00 (SD 5.98) mm (p planning in calcar-guided short-stem total hip arthroplasty assures a satisfying implementation of the intended anatomy. Valgization, which has been frequently observed in previous short-stem designs, negatively affecting offset, can be avoided. However, surgeons have to be aware of a possible leg lengthening.

    Aim: To assess clinical, visual, computerised corneal topographic, and subjective satisfaction with visual acuity, in a cohort of subjects 2 years after phacoemulsification surgery in a public hospital in New Zealand. Methods: Prospective study of a representative sample of 97 subjects (20%) randomly selected from 480 subjects in the original Auckland Cataract Study (ACS) cohort. The clinical assessment protocol was identical to the ACS and included an extensive questionnaire to enable direct comparisons to be made between the two groups. Results: The study population was predominantly female (66%) with a mean age of 76.3 (SD 9.9) years. New systemic and ocular disease affected 18.4% and 10.3% of subjects respectively, and 10.3% required referral to either a general practitioner (2.1%) or ophthalmologist (8.2%). Mean best spectacle corrected visual acuity (BSCVA) was 0.2 (0.2) logMAR units (6/9 Snellen equivalent), with mean spherical equivalent −0.37 (1.01) dioptres (D) and astigmatism −1.07 (0.70) D 2 years postoperatively, compared to mean BSCVA 0.1 (0.2) logMAR units (6/7.5 Snellen equivalent), spherical equivalent −0.59 (1.07) D, and astigmatism −1.14 (0.77) D 4 weeks after surgery. 94.9% of subjects retained a BSCVA of 6/12 or better, irrespective of pre-existing ocular disease. The overall posterior capsule opacification (PCO) rate was 20.4% and this was visually insignificant in all but 3.1% of eyes that had already undergone Nd:YAG posterior capsulotomy. Orbscan II elevation technology demonstrated corneal stability 2 years after uncomplicated phacoemulsification. Although corneal astigmatism was eliminated in approximately half of the subjects 1 month postoperatively, astigmatism showed a tendency to regress towards the preoperative level with local corneal thickening at the site of incision 2 years after cataract surgery. Of fellow eyes, 61.2% had undergone cataract surgery. Overall, 75.3% of subjects were moderately to very satisfied with their

    The aim of this study was to investigate the impact of Daikenchuto (DKT) on early postoperative outcomes after living donor liver transplantation (LDLT), focusing on the prevention of abdominal distension and bacterial translocation. Adult LDLT recipients were prospectively divided into 2 groups, who were administered DKT (n = 20, group A) or not (n = 20, group B). The area of bowel gas defined as gas volume score (GVS) 7 days after LDLT was calculated. Postoperative liver function tests, the development of bacterial, viral, and fungal infections, and GVS after LDLT were reviewed. There were no significant differences in liver function tests and ammonia level after LDLT. Also, the rates of infection and the result of culture study were not different between groups. The median GVS 7 days after LDLT was not significantly different between groups A (0.26 (range, 0.12-0.58)) and B (0.23 (range, 0.15-0.42)). No positive impact was observed for 14-day DKT administration after LDLT, in terms of preventing infection or abdominal distension. Copyright © 2018. Published by Elsevier Taiwan.

    To compare postoperative outcomes of minimally invasive gastrectomy (MIG) to open gastrectomy (OG) for cancer during the introduction of MIG in the Netherlands. Between 2011 and 2015, the use of MIG increased from 4% to 53% in the Netherlands. This population-based cohort study included all patients with curable gastric adenocarcinoma that underwent gastrectomy between 2011 and 2015, registered in the Dutch Upper GI Cancer Audit. Patients with missing preoperative data, and patients in whom no lymphadenectomy or reconstruction was performed were excluded. Propensity score matching was applied to create comparable groups between patients receiving MIG or OG, using year of surgery and other potential confounders. Morbidity, mortality, and hospital stay were evaluated. Of the 1697 eligible patients, 813 were discarded after propensity score matching; 442 and 442 patients who underwent MIG and OG, respectively, remained. Conversions occurred in 10% of the patients during MIG. Although the overall postoperative morbidity (37% vs 40%, P = 0.489) and mortality rates (6% vs 4%, P = 0.214) were comparable between the 2 groups, patients who underwent MIG experienced less wound complications (2% vs 5%, P = 0.006). Anastomotic leakage occurred in 8% of the patients after MIG, and in 7% after OG (P = 0.525). The median hospital stay declined over the years for both procedures (11 to 8 days, P Netherlands, with overall morbidity and mortality comparable with OG, less wound complications and shorter hospitalization.

    Excellent results have recently been reported for both total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA), but there have been few reports about which has a better long-term outcome. The preoperative and postoperative results of TKA and UKA for osteoarthritis of the knee were thus compared. The results of 48 patients who underwent TKA and 25 patients who underwent UKA were evaluated based on clinical scores and survivorship in the middle long-term period. Preoperative, latest postoperative, and changes in the femoro-tibial angle (FTA), range of motion (ROM), Japanese Orthopedic Association score (JOA score), and Japanese Knee Osteoarthritis Measure (JKOM) were compared. The patients' mean age was 73 years. The mean follow-up period was 9 years (TKA: mean, 10.5 years; range, 7-12 years; UKA: mean, 9 years; range, 6-11 years). Preoperative FTA and ROM were significantly higher in the UKA group than in the TKA group. Total changes in all scores were similar among the two groups, as were changes in scores for all JOA and JKOM domains. The cumulative revision rate was higher for UKA than for TKA (7 versus 4%). Kaplan-Meier survivorship at 10 years was 84% for UKA and 92% for TKA. This clinical study found no significant differences between TKA and UKA, except in long-term survivorship.

    Queensland, Australia, has the highest rates of cutaneous squamous cell carcinoma (SCC). Perineural invasion (PNI) is associated with reduced local control and survival. A retrospective review of a prospective database of patients with clinical PNI from cutaneous SCC of the head and neck (SCCHN) treated with surgery and postoperative radiotherapy (PORT) between 2000 and 2011 and a minimum of 24 months follow-up. Patients were excluded if immunosuppressed, had non-SCC histology, or were treated palliatively. Fifty patients (mean age, 60 years) with median follow-up of 50 months were included in this study. A total of 54.8% of known primary tumors had incidental PNI. Ten percent had nodal disease at presentation. MRI neurogram was positive in 95.8%. Recurrence-free survival (RFS) at 5-years was 62%. Five-year disease-specific survival (DSS) and overall survival (OS) were 75% and 64%, respectively. There were no perioperative deaths. This report demonstrates that long-term survival is achievable in patients with clinical PNI from cutaneous SCCHN after surgery and PORT. © 2015 Wiley Periodicals, Inc.

    A substantial proportion of individuals who undergo surgical procedures to relieve spine pain continue to report significant pain and dysfunction after recovery. Psychopathology and patient expectations have been linked to poor results, leading to an increasing reliance on presurgical psychological screening (PPS) as part of the surgical diagnostic process. The original Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) and the MMPI-2 (Butcher, Graham, Ben-Porath, Tellegen, & Dahlstrom, 2001) were among the measures most commonly used in PPS evaluations and research. This study focuses on the newest version of the test, the MMPI-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011; Tellegen & Ben-Porath, 2008/2011) as a predictor of outcomes for spine surgery candidates. Using a sample of 172 men and 210 women who underwent a PPS, we examined the ability of MMPI-2-RF scale scores to predict early surgical outcomes independent of other presurgical risk factors identified by other means, as well as patients' presurgical expectations. MMPI-2-RF results accounted for up to 11% of additional variance in measures of early postoperative functioning. MMPI-2-RF scales that assess for emotional/internalizing problems, specifically Demoralization, measures of somatoform dysfunction, and interpersonal problems contributed most to the prediction of diminished outcome. 2015 APA, all rights reserved

    Maternal education is strongly associated with young child nutrition outcomes. However, the threshold of the level of maternal education that reduces the level of undernutrition in children is not well established. This paper investigates the level of threshold of maternal education that influences child nutrition outcomes using Demographic and Health Survey data from Malawi (2010), Tanzania (2009-10) and Zimbabwe (2005-06). The total number of children (weighted sample) was 4,563 in Malawi; 4,821 children in Tanzania; and 3,473 children in Zimbabwe Demographic and Health Surveys. Using three measures of child nutritional status: stunting, wasting and underweight, we employ a survey logistic regression to analyse the influence of various levels of maternal education on child nutrition outcomes. In Malawi, 45% of the children were stunted, 42% in Tanzania and 33% in Zimbabwe. There were 12% children underweight in Malawi and Zimbabwe and 16% in Tanzania.The level of wasting was 6% of children in Malawi, 5% in Tanzania and 4% in Zimbabwe. Stunting was significantly (p values educational level in all the three countries. Higher levels of maternal education reduced the odds of child stunting, underweight and wasting in the three countries. The maternal threshold for stunting is more than ten years of schooling. Wasting and underweight have lower threshold levels. These results imply that the free primary education in the three African countries may not be sufficient and policies to keep girls in school beyond primary school hold more promise of addressing child undernutrition.

    Background Preoperative knee function is associated with successful postoperative outcome after ACL reconstruction (ACLR). However, there are few longer-term studies of patients who underwent progressive preoperative and postoperative rehabilitation compared to usual care Objectives To compare preoperative and 2 year postoperative patient-reported outcomes (PROs) in patients undergoing progressive preoperative and postoperative rehabilitation at a sports medicine clinic compared with usual care Methods We included patients aged 16–40 years undergoing primary unilateral ACLR. The preoperative and 2 year postoperative KOOS of 84 patients undergoing progressive pre- and postoperative rehabilitation at a sports medicine clinic (Norwegian Research Center for Active Rehabilitation [NAR] cohort) were compared with the scores of 2690 patients from the Norwegian Knee Ligament Registry (NKLR). The analyses were adjusted for sex, age, months from injury to surgery, and cartilage/meniscus injury at ACLR. Results The NAR cohort had significantly better preoperative KOOS in all subscales, with clinically relevant differences (>10 points) observed in KOOS Pain, ADL, Sports and Quality of Life. At 2 years, the NAR cohort still had significantly better KOOS with clinically relevant differences in KOOS Symptoms, Sports and Quality of Life. At 2 years, 85.7–94.0 % of the patients in the NAR cohort scored within the normative range of the different KOOS subscales, compared to 51.4–75.8 % of the patients in the NKLR cohort. Conclusion Patients in a prospective cohort who underwent progressive pre- and postoperative rehabilitation at a sports medicine clinic showed superior patient-reported outcomes both preoperatively and 2 year postoperatively compared to patients in the Norwegian Knee Ligament Registry who received usual care.

    Hypothermic machine perfusion (HPM) grants a better postoperative outcome in transplantation of organs procured from extended criteria donors (ECDs) and donors after cardiac death (DCD). So far, the only available parameter for outcome prediction concerning those organs is pretransplant biopsy score. The aim of this study is to evaluate whether renal resistance (RR) trend during HPM may be used as a predictive marker for post-transplantation outcome. From December 2015 to present, HMP has been systematically applied to all organs from ECDs and DCD. All grafts underwent pretransplantation biopsy evaluation using Karpinski's histological score. Only organs that reached RR value ≤1.0 within 3 hours of perfusion were transplanted. Single kidney transplantation (SKT) or double kidney transplantation (DKT) were performed according to biopsy score results. Sixty-five HMPs were performed (58 from ECDs and 7 from DCD/ECMO donors). Fifteen kidneys were insufficiently reconditioned (RR > 1) and were therefore discarded. Forty-nine kidneys were transplanted, divided between 21 SKT and 14 DKT. Overall primary nonfunction (PNF) and delayed graft function (DGF) rate were 2.9 and 17.1%, respectively. DGF were more common in kidneys from DCD (67 vs. 7%; P = 0.004). Biopsy score did not correlate with PNF/DGF rate (P = 0.870) and postoperative creatinine trend (P = 0.796). Recipients of kidneys that reached RR ≤ 1.0 within 1 hour of HMP had a lower PNF/DGF rate (11 vs. 44%; P = 0.033) and faster serum creatinine decrease (POD10 creatinine: 1.79 mg/dL vs. 4.33 mg/dL; P = 0.019). RR trend is more predictive of post-transplantation outcome than biopsy score. Hence, RR trend should be taken into account in the pretransplantation evaluation of the organs. © 2018 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

    The incidence and consequence of an anastomotic leak associated with low anterior resection for cancer mandates covering stoma in most cases. A water-soluble enema is often performed to assess anastomotic integrity prior to stoma reversal. The functional outcome following reversal in patients with occult radiologically detected leaks is poorly defined. The goal of the present study was to determine the functional outcome in patients with a radiologically detected anastomotic leak who subsequently underwent stoma reversal. This case control study used patients with and without radiologically detected occult anastomotic leak having undergone reversal of covering stomata. The study group was matched with controls for age, gender, procedure, tumor stage, and adjuvant/neoadjuvant therapy. Validated fecal incontinence quality of life (FIQL), Cleveland Clinic Fecal Incontinence Score (CCFIS), and the Memorial Sloan-Kettering Cancer Center (MSKCC) Bowel Function Index (BFI) were used. Patient satisfaction, medication use, and ancillary procedures prior to closure were also recorded. Thirteen patients with radiologically detected occult anastomotic leaks and 13 matched controls were identified from a prospectively maintained database. The FIQL, CCFIS, and MSKCC BFI scores were significantly reduced in those with occult leaks. The mean number of radiological and surgical interventions was significantly greater in the patients with occult leaks. Antidiarrheal and bulking agent use, as well as patient satisfaction, were the same for both groups. Only one patient in the occult leak group would not undergo stoma reversal again. Reversal of a defunctioning ileostomy in the presence of an occult radiological leak can be associated with poorer functional outcomes, but patient satisfaction is undiminished.

    There is a lack of high-level evidence on the surgical management of cleft palate. An appreciation of the differences in the complication rates between different surgical techniques and timing of repair is essential in optimizing cleft palate management. A comprehensive electronic database search will be conducted on the complication rates associated with cleft palate repair using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. Two independent reviewers with expertise in cleft pathology will screen all appropriate titles, abstracts, and full-text publications prior to deciding whether each meet the predetermined inclusion criteria. The study findings will be tabulated and summarized. The primary outcomes will be the rate of palatal fistula, the incidence and severity of velopharyngeal insufficiency, and the rate of maxillary hypoplasia with different techniques and also the timing of the repair. A meta-analysis will be conducted using a random effects model. The evidence behind the optimal surgical approach to cleft palate repair is minimal, with no gold standard technique identified to date for a certain type of cleft palate. It is essential to appreciate how the complication rates differ between each surgical technique and each time point of repair, in order to optimize the management of these patients. A more critical evaluation of the outcomes of different cleft palate repair methods may also provide insight into more effective surgical approaches for different types of cleft palates.

    This paper reports on the importance of postoperative radiology. Most surgical procedures on the alimentary tract are successful, but postoperative complications remain a common occurrence. The radiologist must be familiar with a large variety of possible surgical complications, because it is this specialty that is most commonly called on to render a definitive diagnosis. The decision for reoperation, for instance, is usually based on results from radiologic imaging techniques. These now include ultrasonography, CT scanning, needle biopsy, and interventional techniques in addition to contrast studies and nuclear medicine investigation

    Background As many of 3% of bariatric surgery candidates are diagnosed with a bipolar spectrum disorder. Objectives 1) To describe differences between patients with bipolar spectrum disorders who are approved and not approved for surgery by the mental health evaluator. 2) To examine surgical outcomes of patients with bipolar spectrum disorders. Setting Academic medical center, United States. Methods A retrospective record review was conducted of consecutive patients who applied for bariatric surgery between 2004 and 2009. Patients diagnosed with bipolar spectrum disorders who were approved for surgery (n=42) were compared with patients with a bipolar spectrum disorder who were not approved (n=31) and to matched control surgical patients without a bipolar spectrum diagnosis (n=29) on a variety of characteristics and surgical outcomes. Results Of bariatric surgery candidates diagnosed with a bipolar spectrum disorder who applied for surgery, 57% were approved by the psychologist and 48% ultimately had surgery. Patients with a bipolar spectrum disorder who were approved for surgery were less likely to have had a previous psychiatric hospitalizations than those who were not approved for surgery. Bariatric surgery patients diagnosed with a bipolar spectrum disorder were less likely to attend follow-up care appointments 2 or more years post-surgery compared to matched patients without bipolar disorder. Among patients with available data, those with a bipolar spectrum disorder and matched patients had similar weight loss at 12 months (n=21 for bipolar, n=24 for matched controls) and at 2 or more years (mean=51 months; n=11 for bipolar, n=20 for matched controls). Conclusions Patients diagnosed with a bipolar spectrum disorder have a high rate of delay/denial for bariatric surgery based on the psychosocial evaluation and are less likely to attend medical follow-up care 2 or more years post-surgery. Carefully screened patients with bipolar disorder who engage in long

    Purpose: To assess the clinical outcomes of patients with Stage IA endometrial cancer with myometrial invasion treated with postoperative vaginal brachytherapy (VBT) with those who received no adjuvant therapy (NAT). Methods and Materials: All patients treated with hysterectomy for endometrial cancer at Northwestern Memorial Hospital between 1978 and 2005 were identified. Those patients with Stage IA disease with myometrial invasion who were treated with VBT alone or NAT were identified and included in the present analysis. Results: Of 252 patients with Stage IA endometrial cancer with superficial (<50%) myometrial invasion who met the inclusion criteria, 169 underwent VBT and 83 received NAT. The median follow-up in the VBT and NAT groups was 103 and 61 months, respectively. In the VBT group, 56.8% had Grade 1, 37.9% had Grade 2, and 5.3% had Grade 3 tumors. In the NAT group, 75.9%, 20.5%, and 3.6% had Grade 1, 2, and 3 tumors, respectively. Lymphatic or vascular space invasion was noted in 12.4% of the VBT patients and 5.6% of the NAT patients. The 5-year overall survival rate was 95.5%. The 5-year recurrence-free survival rate was 92.4% for all patients, 94.4% for the VBT group, and 87.4% for the NAT group (p = NS). Of the 169 VBT patients and 83 NAT patients, 8 (4.7%) and 6 (7.2%) developed recurrent disease. One vaginal recurrence occurred in the VBT group (0.6%) and three in the NAT group (3.8%). Recurrences developed 2-102 months after surgical treatment. Two of the four vaginal recurrences were salvaged. No Grade 3 or higher acute or late radiation toxicity was noted. Conclusions: The use of postoperative VBT in patients with Stage I endometrial cancer with <50% myometrial invasion yielded excellent vaginal disease control and disease-free survival, with minimal toxicity.

    Purpose: To report outcomes of the rare disease of squamous cell carcinoma (SCC) of the external auditory canal (EAC) and middle ear treated with surgery and postoperative intensity-modulated radiotherapy (IMRT). Failure patterns related to spatial dose distribution were also analyzed to provide insight into target delineation. Methods and Materials: A retrospective review was conducted of the records of 11 consecutive patients with SCC of the EAC and middle ear who were treated with curative surgery and postoperative IMRT at one institution between January 2007 and February 2010. The prescribed IMRT dose was 60 to 66 Gy at 2 Gy per fraction. Three patients also received concurrent cisplatin-based chemotherapy, and 1 patient received concurrent oral tegafur/uracil. The median follow-up time was 19 months (range, 6-33 months). Results: Four patients had locoregional recurrence, yielding an estimated 2-year locoregional control rate of 70.7%. Among them, 1 patient had persistent disease after treatment, and 3 had marginal recurrence. Distant metastasis occurred in 1 patient after extensive locoregional recurrence, yielding an estimated 2-year distant control rate of 85.7%. The estimated 2-year overall survival was 67.5%. The three cases of marginal recurrence were near the preauricular space and glenoid fossa of the temporomandibular joint, adjacent to the apex of the ear canal and glenoid fossa of the temporomandibular joint, and in the postauricular subcutaneous area and ipsilateral parotid nodes, respectively. Conclusions: Marginal misses should be recognized to improve target delineation. When treating SCC of the EAC and middle ear, care should be taken to cover the glenoid fossa of the temporomandibular joint and periauricular soft tissue. Elective ipsilateral parotid irradiation should be considered. The treatment planning procedure should also be refined to balance subcutaneous soft-tissue dosimetry and toxicity.

    Full Text Available Abstract Background Autogenous Iliac Crest Bone Graft (ICBG has been the "gold standard" for spinal fusion. However, bone graft harvest may lead to complications, such as chronic pain, numbness, and poor cosmesis. The long-term impact of these complications on patient function and well-being has not been established but is critical in determining the value of expensive bone graft substitutes such as recombinant bone morphogenic protein. We thus aimed to investigate the long-term complications of ICBG. Our second aim was to evaluate the psychometric properties of a new measure of ICBG morbidity that would be useful for appropriately gauging spinal surgery outcomes. Methods Prospective study of patients undergoing spinal fusion surgery with autologous ICBG. The SF-36v2, Oswestry Disability Index, and a new 14-item follow-up questionnaire addressing persistent pain, functional limitation, and cosmesis were administered with an 83% response rate. Multiple regression analyses examined the independent effect of ICBG complications on physical and mental health and disability. Results The study population included 170 patients with a mean age of 51.1 years (SD = 12.2 and balanced gender (48% male. Lumbar fusion patients predominated (lumbar = 148; cervical n = 22. At 3.5 years mean follow-up, 5% of patients reported being bothered by harvest site scar appearance, 24% reported harvest site numbness, and 13% reported the numbness as bothersome. Harvest site pain resulted in difficulty with household chores (19%, recreational activity (18%, walking (16%, sexual activity (16%, work activity (10%, and irritation from clothing (9%. Multivariate regression analyses revealed that persistent ICBG complications 3.5 years post-surgery were associated with significantly worse disability and showed a trend association with worse physical health, after adjusting for age, workers' compensation status, surgical site pain, and arm or leg pain. There was no association

    Describe the surgical technique, complications, and long-term outcomes of total pancreatectomy and islet autotransplantation (TP-IAT) in a large series of pediatric patients. Surgical management of childhood pancreatitis is not clear; partial resection or drainage procedures often provide transient pain relief, but long-term recurrence is common due to the diffuse involvement of the pancreas. Total pancreatectomy (TP) removes the source of the pain, whereas islet autotransplantation (IAT) potentially can prevent or minimize TP-related diabetes. Retrospective review of 75 children undergoing TP-IAT for chronic pancreatitis who had failed medical, endoscopic, or surgical treatment between 1989 and 2012. Pancreatitis pain and the severity of pain statistically improved in 90% of patients after TP-IAT (P Puestow procedure (P = 0.018), lower body surface area (P = 0.048), higher islet equivalents (IEQ) per kilogram body weight (P = 0.001), and total IEQ (100,000) (P = 0.004) were associated with insulin independence. By multivariate analysis, 3 factors were associated with insulin independence after TP-IAT: (1) male sex, (2) lower body surface area, and (3) higher total IEQ per kilogram body weight. Total IEQ (100,000) was the single factor most strongly associated with insulin independence (odds ratio = 2.62; P < 0.001). Total pancreatectomy and islet autotransplantation provides sustained pain relief and improved quality of life. The β-cell function is dependent on islet yield. Total pancreatectomy and islet autotransplantation is an effective therapy for children with painful pancreatitis that failed medical and/or endoscopic management.

    Full Text Available Purpose: Robot-assisted radical cystectomy (RARC was originally intended to replace open radical cystectomy (ORC as a minimally invasive surgery for patients with invasive bladder cancer. The purpose of this study was to evaluate the advantages of robotic surgery, comparing perioperative and oncologic outcomes between RARC and ORC. Materials and Methods: Between June 2012 and August 2016, 49 bladder cancer patients were given a radical cystectomy, 21 robotically and 28 by open procedure. We compared the clinical variables between the RARC and ORC groups. Results: In the RARC group, the median estimated blood loss (EBL during cystectomy, total EBL, operative time during cystectomy, and total operative time were 0 mL, 457.5 mL, 199 minutes, and 561 minutes, respectively. EBL during cystectomy (p<0.001, total EBL (p<0.001, and operative time during cystectomy (p=0.003 in the RARC group were significantly lower compared with the ORC group. Time to resumption of a regular diet (p<0.001 and length of stay (p=0.017 were also significantly shorter compared with the ORC group. However, total operative time in the RARC group (median, 561 minutes was significantly longer compared with the ORC group (median, 492.5 minutes; p=0.015. Conclusions: This Japanese study presented evidence that RARC yields benefits in terms of BL and time to regular diet, while consuming greater total operative time. RARC may be a minimally invasive surgical alternative to ORC with less EBL and shorter length of stay.

    To appraise the level of evidence supporting the measurement properties of patient-reported outcome measures (PROMs) in the context of postoperative recovery after abdominal surgery. There is growing interest in using PROMs to support value-based care in abdominal surgery; however, to draw valid conclusions regarding patient-reported outcomes data, PROMs with robust measurement properties are required. Eight databases (MEDLINE, EMBASE, Biosis, PsycINFO, The Cochrane Library, CINAHL, Scopus, Web of Science) were searched for studies focused on the measurement properties of PROMs in the context of recovery after abdominal surgery. The methodological quality of individual studies was evaluated using the consensus-based COSMIN checklist. Evidence supporting the measurement properties of each PROM was synthetized according to standardized criteria and compared against the International Society of Quality of Life Research minimum standards for the selection of PROMs for outcomes research. We identified 35 studies evaluating 22 PROMs [12 focused on nonspecific surgical populations (55%), 4 focused on abdominal surgery (18%), and 6 generic PROMs (27%)]. The great majority of the studies (74%) received only poor or fair quality ratings. Measurement properties of PROMs were predominantly supported by limited or unknown evidence. None of the PROMs fulfilled International Society of Quality of Life Research's minimum standards, hindering specific recommendations. There is very limited evidence supporting the measurement properties of existing PROMs used in the context of recovery after abdominal surgery. This precludes the use of these PROMs to support value-based surgical care. Further research is required to bridge this major knowledge gap.

    Full Text Available Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of post-operative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication.

    Full Text Available Schistosoma haematobium and Schistosoma mansoni are prevalent in Zimbabwe to levels that make schistosomiasis a public health problem. Following three national surveys to map the disease prevalence, a national policy on control of schistosomiasis and soil transmitted helminths is being developed. This paper reviews the experiences that Zimbabwe has in the area of schistosomiasis control with a view to influence policy. A case study approach to highlight key experiences and outcomes was adopted. The benefits derived from intersectoral collaboration that led to the development of a model irrigation scheme that incorporates schistosomiasis control measures are highlighted. Similarly, the benefits of using plant molluscicides and fish and duck biological agents (Sargochromis codringtonii and Cairina moschata are highlighted. Emphasis was also placed on the importance of utilizing locally developed water and sanitation technologies and the critical human resource base in the area of schistosomiasis developed over years. After synthesis of the case studies presented, it was concluded that while there is a need to follow the WHO recommended guidelines for schistosomiasis control it is important to develop a control strategy that is informed by work already done in the country. The importance of having a policy and local guidelines for schistosomiasis control is emphasized.

    As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material. Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis. In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used. In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary. In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.

    Full Text Available Introduction. Laparoscopic liver resection is considered risky in cirrhotic patients, even if minor surgical trauma of laparoscopy could be useful to prevent deterioration of a compromised liver function. This study aimed to identify the differences in terms of perioperative complications and early outcome in cirrhotic patients undergoing minor hepatic resection for hepatocellular carcinoma with open or laparoscopic technique. Methods. In this retrospective study, 156 cirrhotic patients undergoing liver resection for hepatocellular carcinoma were divided into two groups according to type of surgical approach: laparoscopy (LS group: 23 patients or laparotomy (LT group: 133 patients. Perioperative data, mortality, and length of hospital stay were recorded. Results. Groups were matched for type of resection, median number of nodules, and median diameter of largest lesions. Groups were also homogeneous for preoperative liver and renal function tests. Intraoperative haemoglobin decrease and transfusions of red blood cells and fresh frozen plasma were significantly lower in LS group. MELD score lasted stable after laparoscopic resection, while it increased in laparotomic group. Postoperative liver and renal failure and mortality were all lower in LS group. Conclusions. Lower morbidity and mortality, maintenance of liver function, and shorter hospital stay suggest the safety and benefit of laparoscopic approach.

    Sugammadex can rapidly reverse deep neuromuscular blockade, but due to cost questions remain as to its optimal utilization. After introduction for unrestricted use at an academic medical center, we hypothesized that reductions would be demonstrated in the primary outcome of post-anesthesia care unit (PACU) mechanical ventilation (MV) and secondary outcomes of PACU length of stay (LOS), and emergence time (surgery end to anesthesia end time in PACU). We conducted a retrospective observational study of patients undergoing general anesthesia over a 12-month period. Using multiple variable penalized logistic regression in a one group before-and-after design, we compared categorized rates of PACU MV to examine the effect of sugammadex introduction following a post-hoc chart review to ascertain the reason for postoperative MV. Additionally, multiple variable linear regression was used to assess for differences in PACU LOS and emergence time within a propensity matched set of patients receiving neostigmine or sugammadex. 7,217 cases met inclusion criteria: 3,798 before and 3,419 after the introduction of sugammadex. The incidence of PACU MV was 2.3% before and 1.8% after (p=0.118). PACU MV due to residual neuromuscular blockade (rNMB) decreased from 0.63% to 0.20% (p=0.005). Ventilation due to other causes was unchanged. PACU LOS and emergence time were unchanged in a propensity matched set of 1,444 cases. We identified rNMB as an important contributor to PACU MV utilization and observed a significant decrease after sugammadex was introduced. The selected efficiency measures may not have been sufficiently granular to identify improvements following introduction.

  17. Surges and ebbs: National politics and international influence in the formulation and implementation of IWRM in Zimbabwe

    Full Text Available In the 1990s, the Government of Zimbabwe undertook water reforms to redress racially defined inequitable access to agricultural water. This paper analyses how a water reform process, seemingly informed by a clear political economy objective, was hijacked by efforts directed at implementing Integrated Water Resources Management (IWRM. It uses the notion of policy articulation to analyse why and how IWRM 'travelled' to and in Zimbabwe and with what outcomes. The paper shows that attempts at introducing and implementing IWRM in Zimbabwe have had a chequered history. The efforts of Zimbabwe in pioneering implementation of IWRM in southern Africa, have subsequently waned, and prospects for resurrecting IWRM in its original form are low. Introduced in the 1990s when Western donors jumped on the bandwagon of the liberal economic agenda inspired by the IMF/World Bank, it declined between 2000 and 2009 due to a combination of poor economic performance, national-level politics and international isolation. In 2011 IWRM was reintroduced as the country re-engaged with the international community. The re-emergence of IWRM, however, seems to be largely rhetorical as the focus is now on fixing a crisis-ridden water sector, with a new political dispensation adding another layer of complexity. The paper concludes that the development of IWRM in Zimbabwe mirrors broader national-level socio-political processes and their complex relationship with the international community.

    It is essential to preserve as many of the parathyroid glands, as possible, during surgery of the thyroid gland. This is achieved by visualizing them and by minimal handling of the glands. Truncal ligation of the inferior thyroid artery is quite safe. Capsular ligation of the branches of the artery is theoretically superior but requires a greater degree of skill and experience in thyroid surgery. It also puts the recurrent laryngeal nerve at a greater risk of injury. Calcitriol or 1.25 dihydroxy vitamin D is a very useful drug in managing patients with severe post-operative hypoparathyroidism

    To compare clinical intra and early postoperative outcomes between thulium laser transurethral enucleation of the prostate (ThuLEP) and transurethral bipolar resection of the prostate (TURis) for treating benign prostatic hyperplasia (BPH) in a prospective randomized trial. The study randomized 208 consecutive patients with BPH to ThuLEP (n=102) or TURis (n=106). For all patients were evaluated preoperatively with regards to blood loss, catheterization time, irrigation volume, hospital stay and operative time. At 3 months after surgery they were also evaluated by International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), and postvoid residual urine volume (PVR). The patients in each study arm each showed no significant difference in preoperative parameters. Compared with TURIS, ThuLEP had same operative time (53.69±31.44 vs 61.66±18.70minutes, P=.123) but resulted in less hemoglobin decrease (0.45 vs 2.83g/dL, P=.005). ThuLEP also needed less catheterization time (1.3 vs 4.8 days, P=.011), irrigation volume (29.4 vs 69.2 L, P=.002), and hospital stay (1.7 vs 5.2 days, P=.016). During the 3 months of follow-up, the procedures did not demonstrate a significant difference in Qmax, IPSS, PVR, and QOLS. ThuLEP and TURis both relieve lower urinary tract symptoms equally, with high efficacy and safety. ThuLEP was statistically superior to TURis in blood loss, catheterization time, irrigation volume, and hospital stay. However, procedures did not differ significantly in Qmax, IPSS, PVR, and QOLS through 3 months of follow-up. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available BACKGROUND Stomach cancer is the fourth most common malignancy in the world. 1 Except in countries where screening for stomach cancer is prevalent, most of the distal stomach tumours are diagnosed at advanced stage. Gastric outlet obstruction is usually believed to be a sign of locally-advanced disease. Complete surgical removal of the disease (R0 is the only potentially curative treatment for resectable gastric cancer. The aim of the study is to finda The operability rate of gastric cancer in our institution and the incidence of Gastric Outlet Obstruction (GOO in patients undergoing gastrectomy for distal gastric cancer. b To compare the postoperative outcome in patients with gastric outlet obstruction and those without gastric outlet obstruction. c To see if the histology of the tumour has any role in the development of GOO. MATERIALS AND METHODS This is a retrospective study. The study includes patients who were admitted with carcinoma stomach and underwent operative or nonoperative treatment in our institution during 2013 to 2015. RESULTS Overall operability rate was 45.8%. Operable patients in the GOO group were 47%. Operability in the no outlet obstruction group were 45%. Data shows a slightly increased predilection for GOO in diffuse and mixed type of tumours (statistically not significant. Intestinal tumours had significant rate of anaemia compared to diffuse tumours (p <0.005. Overall mortality was 6.7%. Mortality is higher in the GOO group (8.8%. CONCLUSION (a.

    To evaluate the effects of a government insurance programme covering tertiary care for the poor in Karnataka, India--Vajpayee Arogyashree Scheme (VAS)--on treatment seeking and postoperative outcomes. Geographic regression discontinuity. 572 villages in Karnataka, India. 3478 households in 300 villages where VAS was implemented and 3486 households in 272 neighbouring matched villages ineligible for VAS. A government insurance programme that provided free tertiary care to households below the poverty line in half of villages in Karnataka from February 2010 to August 2012. Seeking treatment for symptoms, posthospitalisation well-being, occurrence of infections during hospitalisation and need for rehospitalisation. The prevalence of symptoms was nearly identical for households in VAS-eligible villages compared with households in VAS-ineligible villages. However, households eligible for VAS were 4.96 percentage points (95% CI 1 to 8.9; p=0.014) more likely to seek treatment for their symptoms. The increase in treatment seeking was more pronounced for symptoms of cardiac conditions, the condition most frequently covered by VAS. Respondents from VAS-eligible villages reported greater improvements in well-being after a hospitalisation in all categories assessed and they were statistically significant in 3 of the 6 categories (walking ability, pain and anxiety). Respondents eligible for VAS were 9.4 percentage points less likely to report any infection after their hospitalisation (95% CI -20.2 to 1.4; p=0.087) and 16.5 percentage points less likely to have to be rehospitalised after the initial hospitalisation (95% CI -28.7 to -4.3; p<0.01). Insurance for tertiary care increased treatment seeking among eligible households. Moreover, insured patients experienced better posthospitalisation outcomes, suggesting better quality of care received. These results suggest that there are several pathways through which tertiary care insurance could improve health, aside from

    Full Text Available BACKGROUND: Various devices have been recently employed for percutaneous closure of the patent ductus arteriosus (PDA. Although the high effectiveness of device closure techniques has been clearly determined, a few studies have focused on the cost-effectiveness and also postoperative complications of these procedures in comparison with open surgery. The present study aimed to evaluate the clinical outcome and cost-effectiveness of PDA occlusion by Amplatzer and coil device in comparisong with open surgery. METHODS: In this cross-sectional study, a randomized sample of 201 patients aged 1 month to 16 years (105 patients with device closure and 96 patients with surgical closure was selected. The ratio of total pulmonary blood flow to total systemic blood flow, the Qp/Qs ratio, was measured using a pulmonary artery catheter. The cost analysis included direct medical care costs associated with device implantation and open surgery, as well as professional fees. All costs were calculated in Iranian Rials and then converted to US dollars. RESULTS: There was no statistical difference in mean Qp/Qs ratio before the procedure between the device closure group and the open surgery group (2.1 ± 0.7 versus 1.7 ± 0.6, P = 0.090. The mean measured costs were overall higher in the device closure group than in open closure group (948.87 ± 548.76 US$ versus 743.70 ± 696.91 US$, P < 0.001. This difference remained significant after adjustment for age and gender (Standardized Beta = 0.160, P = 0.031. PDA closure with the Amplatzer ductal occluder (1053.05 ± 525.73 US$ or with Nit-Occlud coils (PFM (912.73 ± 565.94 US$, P < 0.001 was more expensive than that via open surgery. However, the Cook detachable spring coils device closure (605.65 ± 194.62 US$, P = 0.650 had a non-significant cost difference with open surgery.

  19. Zimbabwe culture before Mapungubwe: new evidence from Mapela Hill, South-Western Zimbabwe.

    Across the globe, the emergence of complex societies excites intense academic debate in archaeology and allied disciplines. Not surprisingly, in southern Africa the traditional assumption that the evolution of socio-political complexity began with ideological transformations from K2 to Mapungubwe between CE1200 and 1220 is clouded in controversy. It is believed that the K2-Mapungubwe transitions crystallised class distinction and sacred leadership, thought to be the key elements of the Zimbabwe culture on Mapungubwe Hill long before they emerged anywhere else. From Mapungubwe (CE1220-1290), the Zimbabwe culture was expressed at Great Zimbabwe (CE1300-1450) and eventually Khami (CE1450-1820). However, new fieldwork at Mapela Hill, when coupled with a Bayesian chronology, offers tremendous fresh insights which refute this orthodoxy. Firstly, Mapela possesses enormous prestige stone-walled terraces whose initial construction date from the 11th century CE, almost two hundred years earlier than Mapungubwe. Secondly, the basal levels of the Mapela terraces and hilltop contain élite solid dhaka (adobe) floors associated with K2 pottery and glass beads. Thirdly, with a hilltop and flat area occupation since the 11th century CE, Mapela exhibits evidence of class distinction and sacred leadership earlier than K2 and Mapungubwe, the supposed propagators of the Zimbabwe culture. Fourthly, Mapungubwe material culture only appeared later in the Mapela sequence and therefore post-dates the earliest appearance of stone walling and dhaka floors at the site. Since stone walls, dhaka floors and class distinction are the essence of the Zimbabwe culture, their earlier appearance at Mapela suggests that Mapungubwe can no longer be regarded as the sole cradle of the Zimbabwe culture. This demands not just fresh ways of accounting for the rise of socio-political complexity in southern Africa, but also significant adjustments to existing models.

    We conducted a case study of the Zimbabwe National AIDS Trust Fund ('AIDS Levy') as an approach to domestic government financing of the response to HIV and AIDS. Data came from three sources: a literature review, including a search for grey literature, review of government documents from the Zimbabwe National AIDS Council (NAC), and key informant interviews with representatives of the Zimbabwean government, civil society and international organizations. The literature search yielded 139 sources, and 20 key informants were interviewed. Established by legislation in 1999, the AIDS Levy entails a 3% income tax for individuals and 3% tax on profits of employers and trusts (which excluded the mining industry until 2015). It is managed by the parastatal NAC through a decentralized structure of AIDS Action Committees. Revenues increased from inception to 2006 through 2008, a period of economic instability and hyperinflation. Following dollarization in 2009, annual revenues continued to increase, reaching US$38.6 million in 2014. By policy, at least 50% of funds are used for purchase of antiretroviral medications. Other spending includes administration and capital costs, HIV prevention, and monitoring and evaluation. Several financial controls and auditing systems are in place. Key informants perceived the AIDS Levy as a 'homegrown' solution that provided country ownership and reduced dependence on donor funding, but called for further increased transparency, accountability, and reduced administrative costs, as well as recommended changes to increase revenue. The Zimbabwe AIDS Levy has generated substantial resources, recently over US$35 million per year, and signals an important commitment by Zimbabweans, which may have helped attract other donor resources. Many key informants considered the Zimbabwe AIDS Levy to be a best practice for other countries to follow.

The present study aimed to evaluate the clinical outcome and cost-effectiveness of PDA occlusion by Amplatzer and coil device in comparisong with open surgery. In this cross-sectional study, a randomized sample of 201 patients aged 1 month to 16 years (105 patients with device closure and 96 patients with surgical closure) was selected. The ratio of total pulmonary blood flow to total systemic blood flow, the Qp/Qs ratio, was measured using a pulmonary artery catheter. The cost analysis included direct medical care costs associated with device implantation and open surgery, as well as professional fees. All costs were calculated in Iranian Rials and then converted to US dollars. There was no statistical difference in mean Qp/Qs ratio before the procedure between the device closure group and the open surgery group (2.1 ± 0.7 versus 1.7 ± 0.6, P = 0.090). The mean measured costs were overall higher in the device closure group than in open closure group (948.87 ± 548.76 US$ versus 743.70 ± 696.91 US$, P gender (Standardized Beta = 0.160, P = 0.031). PDA closure with the Amplatzer ductal occluder (1053.05 ± 525.73 US$) or with Nit-Occlud coils (PFM) (912.73 ± 565.94 US$, P < 0.001) was more expensive than that via open surgery. However, the Cook detachable spring coils device closure (605.65 ± 194.62 US$, P = 0.650) had a non-significant cost difference with open surgery. No event was observed in the device closure group regarding in-hospital mortality or morbidity; however, in another group, 2 in-hospital deaths occurred, two patients experienced pneumonia and seizure, and one suffered electrolyte abnormalities including

  8. Challenges of raising road maintenance funds in developing countries: An analysis of road tolling in Zimbabwe

    Directory of Open Access Journals (Sweden)

    T. C. Mbara

    2010-11-01

    Full Text Available The condition of Zimbabwe's roads has been declining due to insufficient maintenance and rehabilitation. Year on year, budget allocations have compared unfavourably with funding considered adequate to maintain highway networks and conduct modest construction work. Road infrastructure shortcomings have manifested themselves in the form of high vehicle operating costs and rampant potholes, leading to a decline in road safety and a deterioration of service levels for those who use roads to deliver goods or connect to international markets. In order to try and stop this vicious cycle of decline, the Government of Zimbabwe, on 8 August 2009, introduced a new policy of road-user charges, which involved the setting-up of 22 toll gates on the trunk road network. The overall objective was to raise revenue in order to close the funding gap, blamed for declining road quality. Although alternative methods of financing road maintenance have been debated for years, a generally accepted understanding is that road users should pay costs for road provisioning. This paper assesses the implementation of a road tolling system in Zimbabwe and describes matters relating to, inter alia, implementation strategy, initial performance outcomes and sustainability.

Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. Results The median follow-up was 45 months. The five-year overall survival (OS and disease-free survival (DFS rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth. In the risk group, there was no local failure in patients with postoperative radiotherapy. Conclusions In T1-2N0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features.

    Transsphenoidal surgery is the treatment of choice for ACTH-producing pituitary adenoma (Cushing's disease) and pituitary irradiation is widely considered the most appropriate treatment for patients with Cushing's disease for whom transsphenoidal surgery has been unsuccessful. We studied 49 consecutive patients who underwent transsphenoidal surgery for the treatment of Cushing's disease at Tokyo Women's Medical University from 1977-1997 with a mean follow-up duration of 87.6 months (range, 24-253 months). We examined the relationship between postoperative endocrinological data, assessed between 3 and 8 weeks after surgery, and long-term outcome and efficacy of pituitary irradiation after surgery. Long-term remission was defined as the regression of the symptom and signs of Cushing's syndrome, and restoration of normal levels of plasma ACTH, cortisol and urinary free cortisol, together with adequate suppression of morning plasma cortisol levels following the administration of low dose (1 mg) of dexamethasone. Thirty patients had no additional treatment after pituitary surgery. Only 1 of 25 patients (4%) whose postoperative plasma cortisol level was less than 2 {mu}g/dl developed recurrent disease whereas 3 out of 5 patients with postoperative plasma cortisol levels higher than 2 {mu}g/dl relapsed. Postoperative external pituitary radiation was used to treat the remaining 19 patients. Four patients who received radiation therapy had a low or undetectable postoperative plasma cortisol level (<2 {mu}g/dl, 56 nmol/L) and all of these patients developed hypopituitarism whereas 5 patients with subnormal plasma cortisol levels (2.0-10.0 {mu}g/dl) remained in remission. Among 10 patients with persistent disease after surgery, 6 entered remission 6-47 months after irradiation but one of them subsequently relapsed after 108 months. These results suggest that additional therapy should be avoided in patients with a postoperative plasma cortisol less

    Full text: Imaging assessment of brain tumors following surgery is complex and depends upon several factors, including the location of the tumor, the surgical procedure and the disease process for which it was performed. Depending upon these factors, one or a combination of complementary imaging modalities may be required to demonstrate any clinically relevant situation, to assist the surgeon in deciding if repeat surgery is necessary. Conventional magnetic resonance imaging (MRI) can show the shape, size, signal intensity, and enhancement of a brain tumor. It has been widely used to diagnose and differentiate brain tumors and to assess the surgery outcomes. Longitudinal MRI scans have also been applied for the assessment of treatment and response to surgery. The newly developed MRI techniques, including diffusion weighted imaging (DWI), perfusion weighted imaging (PWI) and magnetic resonance spectroscopy (MRS), have the potential to provide the molecular, functional and metabolic information of preoperative and postoperative brain tumors. Postoperative diffusion and perfusion magnetic resonance imaging are especially useful in predicting early functional recovery from new deficits after brain tumor surgery.This lecture will stress the principles, applications, and pitfalls of conventional as well as newly developing functional imaging techniques following operation of brain tumors

    Purpose: Evaluation of long-term tumor control, normalization of hormonal hypersecretion, including incidence and time course of pituitary dysfunction following postoperative radiotherapy of pituitary macroadenomas. Patients and Methods: In a retrospective study, the data of 87 patients with pituitary macroadenomas (61 non-secreting adenomas, 26 secreting adenomas) treated between 1984 and 1994 were analyzed. All patients underwent surgery and received postoperative external-beam radiotherapy with a mean dose of 50.4 Gy (range 46-54 Gy). Results: After a follow-up of 15 years the local tumor control rate achieved was 93.0% for non-secreting adenomas and 100% for secreting adenomas, respectively. Normalization of endocrine hypersecretion was noted in 24 of 26 patients (92%). Detailed endocrinological follow-up data were analyzed by an experienced endocrinologist in 77 patients. After a median follow-up of 10.54 years (mean 10.22; range 1.39-20.75 years), in 75 of 77 patients (97%) a hypopituitarism was observed (partial hypopituitarism, n = 28 [36%], panhypopituitarism, n = 47 [61%]), and 68 out of 77 patients (88%) showed evidence of radiotherapy-induced pituitary disorders. The somatotropic function was most commonly affected, followed by gonadal, thyroid and adrenal function. The gonadal axis showed to be the first to be disturbed. 67 patients (87%) required a hormone replacement therapy. Conclusion: Radiotherapy after pituitary surgery is highly effective in reducing hormonal hypersecretion and preventing recurrences of pituitary adenomas. However, pituitary insufficiencies are commonly observed after radiotherapy requiring a close follow-up to ensure timely diagnosis of pituitary dysfunction and an early inception of hormone replacement therapy.

    Postoperative nosocomial infection (PNI) is a severe complication in surgical patients. Known risk factors of PNI such as allogeneic blood transfusions (ABTs), anemia, and iron deficiency are manageable with perioperative intravenous (IV) iron therapy. To address potential concerns about IV iron and the risk of PNI, we studied a large series of orthopedic surgical patients for possible relations between IV iron, ABT, and PNI. Pooled data on ABT, PNI, 30-day mortality, and length of hospital stay (LHS) from 2547 patients undergoing elective lower-limb arthroplasty (n = 1186) or hip fracture repair (n = 1361) were compared between patients who received either very-short-term perioperative IV iron (200-600 mg; n = 1538), with or without recombinant human erythropoietin (rHuEPO; 40,000 IU), or standard treatment (n = 1009). Compared to standard therapy, perioperative IV iron reduced rates of ABT (32.4% vs. 48.8%; p = 0.001), PNI (10.7% vs. 26.9%; p = 0.001), and 30-day mortality (4.8% vs. 9.4%; p = 0.003) and the LHS (11.9 days vs. 13.4 days; p = 0.001) in hip fracture patients. These benefits were observed in both transfused and nontransfused patients. Also in elective arthroplasty, IV iron reduced ABT rates (8.9% vs. 30.1%; p = 0.001) and LHS (8.4 days vs.10.7 days; p = 0.001), without differences in PNI rates (2.8% vs. 3.7%; p = 0.417), and there was no 30-day mortality. Despite known limitations of pooled observational analyses, these results suggest that very-short-term perioperative administration of IV iron, with or without rHuEPO, in major lower limb orthopedic procedures is associated with reduced ABT rates and LHS, without increasing postoperative morbidity or mortality. © 2013 American Association of Blood Banks.

    BACKGROUND: Vitamin A has widespread effects on immune function and is therefore interesting in HIV-infection. Retinol-binding protein (RBP or RBP4) is a negative acute-phase protein and a marker of vitamin A status. Our aim was to investigate the association of RBP with HIV progression, infection...... with schistosomiasis, inflammatory cytokines, and mortality. METHODS: The study included 192 HIV-infected and 177 HIV-uninfected individuals from Mupfure in rural Zimbabwe. Of these, 208 were infected with Schistosoma haematobium, 27 with S. mansoni and 48 with both. Plasma RBP, HIV-RNA, CD4 cell count, haemoglobin......, cytokines, clinical staging (CDC category), self-reported level of function (Karnoffsky Performance Score, KPS) and schistosomiasis status were assessed at baseline. Participants were followed up for survival 3-4 years post-enrolment. RESULTS: RBP levels were lower in HIV-infected individuals(p

    Laboratory tests on traditional open fires as methods of cooking give values of thermal efficiency varying from 12-30%. These are significantly higher than values which are widely quoted in the literature. The results of a research visit to Zimbabwe indicated that in three villages fuel efficiency did not appear to be the main determinant of choice of cooking method: villagers had changed from their traditional mode of cooking to stoves which they perceived to consume substantially more fuel. These stoves enable meals to be prepared more quickly which the women found useful during the busy months. The increased labour costs could be borne because the fuel was gathered during the slack season.

  17. Maternal education and child mortality in Zimbabwe.

    Grépin, Karen A; Bharadwaj, Prashant

    2015-12-01

    In 1980, Zimbabwe rapidly expanded access to secondary schools, providing a natural experiment to estimate the impact of increased maternal secondary education on child mortality. Exploiting age specific exposure to these reforms, we find that children born to mothers most likely to have benefited from the policies were about 21% less likely to die than children born to slightly older mothers. We also find that increased education leads to delayed age at marriage, sexual debut, and first birth and that increased education leads to better economic opportunities for women. We find little evidence supporting other channels through which increased education might affect child mortality. Expanding access to secondary schools may greatly accelerate declines in child mortality in the developing world today. Copyright © 2015 Elsevier B.V. All rights reserved.

    Despite the increasing severity of droughts and their effects on Zimbabwe's agriculture, there are few tools available for predicting these droughts in advance. Consequently, communities and farmers are more exposed, and policy makers are always ill prepared for such. This study sought to investigate possible cycles and precursor meteorological conditions prior to drought seasons that could be used to predict impending droughts in Zimbabwe. The Single Z-Index was used to identify and grade drought years between 1951 and 2010 according to rainfall severity. Spectral analysis was used to reveal the cycles of droughts for possible use of these cycles for drought prediction. Composite analysis was used to investigate circulation and temperature anomalies associated with severe and extreme drought years. Results indicate that severe droughts are more highly correlated with circulation patterns and embedded weather systems in the Indian Ocean and equatorial Pacific Ocean than any other area. This study identified sea surface temperatures in the average period June to August, geopotential height and wind vector in July to September period, and air temperature in September to November period as precursors that can be used to predict a drought occurrence several months in advance. Therefore, in addition to sea surface temperature, which was identified through previous research for predicting Zimbabwean droughts, the other parameters identified in this study can aid in drought prediction. Drought cycles were established at 20-, 12.5-, 3.2-, and 2.7-year cycles. The spectral peaks, 12.5, 3.2, and 2.7, had a similar timescale with the luni-solar tide, El Niño Southern Oscillation and Quasi Biennial Oscillation, respectively, and hence, occurrence of these phenomena have a possibility of indicating when the next drought might be.

    Full Text Available Zimbabwe has experienced an unprecedented decline of nearly all human development indicators for the past ten years. Despite the introduction of community gardens in drought-prone areas of Zimbabwe, poverty persists amongst the vulnerable groups. The potential to improve household, community and national food and nutrition security through garden activities is high if issues of water availability cost and availability of inputs, marketing and farmer empowerment can be addressed. This paper seeks to assess the community garden's cost structure to sales volume and profitability and the land use efficiency. Primary data were collected through structured questionnaire. A two stage sampling techniques was used to select respondents. The study was conducted in Zaka district. Three major crops namely tomatoes, covo and onion were chosen for the study basing on size of land under that particular crop. Cost-Volume-Profit analysis employed for analysis of cost structure to sales volume and profitability. Land use efficiency was also employed to measure the ratio yield per acre of farm to average yield of locality. The results showed that although the farmers are able to break even the margin of safety is small especially for cove and onion. The study recommends farmers to increase the size of acreage under onion production whilst reduce acreage under production of covo. Farmers should adopt technology that would improve land use efficiency of onion. There is a need for the intervention by the Government and other stakeholders to improve the profitability and efficiency of the community gardeners. Stakeholders' collaboration especially, in terms of farmer training which can improve garden activities as participants lack knowhow.

    Acute gastrointestinal (GI) wall defects contain a high risk of morbidity and mortality and may be closed endoscopically by a full-thickness over-the-scope clip (OTSC). Unselected consecutive patients presenting with acute non-surgical perforations or postoperative anastomotic leaks or perforations underwent attempted OTSC placement as primary closure method after interdisciplinary consensus in three tertiary referral centres. Their clinical data and intervention characteristics were evaluated in an intention to treat analysis during a 24-month period to assess closure rates, 30-day mortality, hospitalization and comorbidity. In total, 34 patients (16 females, 18 males, 69.5 years) were included with 22 non-surgical perforations and 12 postoperative anastomotic leaks or perforations. Definitive closure of the perforations and leaks was achieved in 26/34 patients (76.5 %). Successful closure of the GI wall defect resulted in a significantly shorter hospital stay (8 days, p = 0.03) and was significantly correlated with comorbidity (r = 0.56, p = 0.005). In the group with OTSC failure, hospitalization was 18 days and 6 of 8 patients (75 %) required immediate surgery. Three deaths occurred in the group with successful OTSC closure due to comorbidity, while one death in the OTSC failure group was related to a refractory perforation. Favourable indications and locations for a successful OTSC procedure were identified as PEG complications, endoscopic or postoperative leaks of stomach, colon or rectum, respectively. In unselected patients, OTSC was effective for closure of acute GI wall defects in more than 75 % of all patients. Clinical success and short hospitalization were best achieved in patients without comorbidity, but closure of the perforation or the anastomotic leak was found to be not the only parameter relevant for patient outcome and mortality.

    Intravenous thrombolysis (IVT) is beneficial in reducing disability in selected patients with acute ischemic stroke. There are numerous contraindications to IVT. One is recent surgery. The aim of this study was to analyze the safety of IVT in patients with postoperative stroke. Data of consecutive IVT patients from the Telemedical Project for Integrative Stroke Care thrombolysis registry (February 2003 to October 2014; n=4848) were retrospectively searched for keywords indicating preceding surgery. Patients were included if surgery was performed within the last 90 days before stroke. The primary outcome was defined as surgical site hemorrhage. Subgroups with major/minor surgery and recent/nonrecent surgery (within 10 days before IVT) were analyzed separately. One hundred thirty-four patients underwent surgical intervention before IVT. Surgery had been performed recently (days 1-10) in 49 (37%) and nonrecently (days 11-90) in 85 patients (63%). In 86 patients (64%), surgery was classified as major, and in 48 (36%) as minor. Nine patients (7%) developed surgical site hemorrhage after IVT, of whom 4 (3%) were serious, but none was fatal. One fatal bleeding occurred remotely from surgical area. Rate of surgical site hemorrhage was significantly higher in recent than in nonrecent surgery (14.3% versus 2.4%, respectively, odds ratio adjusted 10.73; 95% confidence interval, 1.88-61.27). Difference between patients with major and minor surgeries was less distinct (8.1% and 4.2%, respectively; odds ratio adjusted 4.03; 95% confidence interval, 0.65-25.04). Overall in-hospital mortality was 8.2%. Intracranial hemorrhage occurred in 9.7% and was asymptomatic in all cases. IVT may be administered safely in postoperative patients as off-label use after appropriate risk-benefit assessment. However, bleeding risk in surgical area should be taken into account particularly in patients who have undergone surgery shortly before stroke onset. © 2017 American Heart Association, Inc.

    To assess the impact of Zimbabwe's National Behavioural Change Programme (NBCP) on biological and behavioral outcomes. Representative household biobehavioral surveys of 18- to 44-year-olds were conducted in randomly selected enumeration areas in 2007 and 2011 to 2012. We examined program impact on HIV prevalence among young women, nonregular partnerships, condom use with nonregular partners, and HIV testing, distinguishing between highly exposed and low-exposed communities and individuals. We conducted (1) difference-in-differences analyses with communities as unit of analysis and (2) analyses of key outcomes by individual-level program exposure. Four thousand seven hundred seventy-six people were recruited in 2007 and 10,059 in 2011 to 2012. We found high exposure to NBCP in 2011. Prevalence of HIV and reported risky behaviors declined between 2007 and 2011. Community-level analyses showed a smaller decline in HIV prevalence among young women in highly exposed areas (11.0%-10.1%) than low-exposed areas (16.9%-10.3%, P = 0.078). Among young men, uptake of nonregular partners declined more in highly exposed areas (25%-16.8%) than low-exposed areas (21.9%-20.7%, P = 0.055) and HIV testing increased (27.2%-46.1% vs. 31.0%-34.4%, P = 0.004). Individual-level analyses showed higher reported condom use with nonregular partners among highly exposed young women (53% vs. 21% of unexposed counterparts, P = 0.037). We conducted the first impact evaluation of a NBCP and found positive effects of program exposure on key behaviors among certain gender and age groups. HIV prevalence among young women declined but could not be attributed to program exposure. These findings suggest substantial program effects regarding demand creation and justify program expansion.

    We evaluated the short-term and mid-term differences in perfusion and function after off-pump and on-pump coronary artery bypass grafting (CABG) using gated myocardial single photon emission computed tomography. A total of 70 patients with coronary artery disease who underwent CABG were included based on the propensity score matching results from 165 patients. Thirty-five patients underwent off-pump and 35 patients on-pump CABG. Rest 201 TI/dipyridamole stress 99m Tc-methoxyisobutylisonitrile gated single photon emission computed thermographs were performed preoperatively and postoperatively at short-term (103±23 days after surgery) and mid-term follow-up (502±111 days after surgery). Changes in left ventricular ejection fraction, end systolic volume, stress and rest segmental perfusion, and segmental wall thickening were compared between the two groups. The segments with preoperative rest 201 T1 uptake under 60% of maximum uptake were included in the segmental analysis. Left ventricular ejection fraction (P=0.001) and end systolic volume (P=0.008) showed significant improvement in both groups. There were no significant short-term and mid-term differences between the two groups in terms of left ventricular ejection fraction (P=0.309) and end systolic volume (P=0.938). Likewise, segmental rest (P=0.178) and stress perfusion (P=0.071), and systolic wall thickening (P=0.241) showed significant improvement in both groups with similar time courses. Off-pump CABG resulted in significant improvements in left ventricular ejection fraction, end systolic volume, and regional myocardial perfusion and function that are comparable to on-pump CABG at short-term and mid-term. Gated myocardial SPECT successfully revealed that off-pump CABG is as good as on-pump CABG from the viewpoint of myocardial perfusion and function.

    To evaluate the short and long term outcomes of duodenum preserving pancreatic head resection (DPPHR) procedures in the treatment of painful chronic pancreatitis. A systematic literature search was performed to identify all comparative studies evaluating long and short term postoperative outcomes (pain relief, morbidity and mortality, pancreatic exocrine and endocrine function). Five published studies fulfilled the inclusion criteria including 1 randomized controlled trial comparing the Beger and Frey procedure. In total, 323 patients underwent surgical procedures for chronic pancreatitis, including Beger (n = 138) and Frey (n = 99), minimal Frey (n = 32), modified Frey (n = 25) and Berne's modification (n = 29). Two studies comparing the Beger and Frey procedure were entered into a meta-analysis and showed no difference in post-operative pain (RD = -0.06; CI -0.21 to 0.09), mortality (RD = 0.01; CI -0.03 to 0.05), morbidity (RD = 0.12; CI -0.00 to 0.24), exocrine insufficiency (RD = 0.04; CI -0.10 to 0.18) and endocrine insufficiency (RD = -0.14 CI -0.28 to 0.01). All procedures are equally effective for the management of pain for chronic pancreatitis. The choice of procedure should be determined by other factors including the presence of secondary complications of pancreatitis and intra-operative findings. Registration number CRD42015019275.

    Full Text Available Several challenges involving torture-related human rights violations have been reported in Zimbabwe from the late 1970s to date. Notably, these torture-related human rights violations were problematic during the liberation war era in Zimbabwe. Regrettably, such violations are allegedly still prevalent, especially prior to and/or during general political elections in Zimbabwe. Accordingly, this article investigates torture as a human rights violation in Zimbabwe, inter alia by focusing on the role of selected law enforcement agencies in the protection of human rights in Zimbabwe. The article also discusses the legal position on torture and the perpetration of torture against ordinary people prior to as well as after independence in Zimbabwe. This is done to investigate the adequacy of the legal framework in Zimbabwe with regard to the combatting of torture. In relation to this, selected regional and international legal frameworks against torture are briefly discussed in order to determine possible measures that could be utilised in Zimbabwe. The authors submit that although the Constitution of Zimbabwe Amendment (No 20 Act, 2013 (Zimbabwe Constitution, 2013 prohibits torture, more may still need to be done to enhance the combatting of torture in Zimbabwe. For instance, apart from the prohibition contained in the Zimbabwe Constitution, 2013, there is no legislation that expressly outlaws torture in Zimbabwe. Moreover, Zimbabwe has not ratified the United Nations (UN Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment of 1984 (UN Convention against Torture to date. Lastly, concluding remarks and possible recommendations that could be employed to discourage torture-related human rights abuses in Zimbabwe are provided.

    Assessing functional outcome from patient-based outcomes questionnaires are essential to the evaluation of adolescent idiopathic scoliosis surgical treatment At the minimum follow-up of 2 years, 45 operated on adolescent idiopathic scoliosis patients were mailed the French version of the Scoliosis Research Society Outcome Instrument (SRS-22) questionnaires containing items on pain, activities of daily living, and satisfaction. Mean values of the SRS-22 domains were 3,66 for the Pain domain, 3,85 for the Self-perceived image domain, 4,32 for the Function domain, 3,52 for the Mental health domain and 4,12 for the Global satisfaction with management domain. Mean value of the global SRS-22 score was 3,88. We showed no differences in functional SRS-22 health status in patients according to the type of curve (Lenke classification). We showed statistically significant correlations between the gain of Cobb angle and Patients self-image and function domain scores. There was a statistically significant correlation between preoperative Cobb angle and patient satisfaction with management. Even if Function and Self-image scores in our patients are close to control group values, indicating good short to mid-term outcome of surgical treatment, scores for pain and mental health status were significantly lower in patients than controls. Long-term follow-up studies conducted by multiple surgeons over successive generations are mandatory to assess clinical significance of these differences. Level IV. Retrospective study.

    Laser in situ keratomileusis (LASIK) means a patient investment of 2426 Euro per eye, which usually cannot be funded by European health care insurers. In the context of recent resource allocation discussions, however, the cost effectiveness of LASIK could become an important indication of allocation decisions. Therefore an evidence based estimation of its incremental cost effectiveness was intended. Three independent meta analyses were implemented to estimate the refractive gain (dpt) due to conventional LASIK procedures as well as the predictability of the latter (%) (fraction of eyes achieving a postoperative refraction with maximum deviation of +/- 0.5 dpt from the target refraction). Study reports of 1995 - 2004 (English or German language) were screened for appropriate key words. Meta effects in refractive gain and predictability were estimated by means and standard deviations of reported effect measures. Cost data were estimated by German DRG rates and individual clinical pathway calculations; cost effectiveness was then computed in terms of the incremental cost effectiveness ratio (ICER) for both clinical benefit endpoints. A sensitivity analysis comprised cost variations of +/- 10 % and utility variations alongside the meta effects' 95% confidence intervals. Total direct costs from the patients' perspective were estimated at 2426 Euro per eye, associated with a refractive meta benefit of 5.93 dpt (95% meta confidence interval 5.32 - 6.54 dpt) and a meta predictability of 67% (43% - 91%). In terms of incremental costs, the unilateral LASIK implied a patient investion of 409 Euro (sensitivity range 351 - 473 Euro) per gained refractive unit or 36 Euro (27 - 56 Euro) per gained percentage point in predictability. When LASIK associated complication patterns were considered, the total direct costs amounted up to 3075 Euro, resulting in incremental costs of 519 Euro / dpt (sensitivity range 445 - 600 Euro / dpt) or 46 Euro / % (34 - 72 Euro / %).

    Objective To determine the effectiveness and safety of perioperative tranexamic acid use in patients undergoing total hip or knee arthroplasty in the United States. Design Retrospective cohort study; multilevel multivariable logistic regression models measured the association between tranexamic acid use in the perioperative period and outcomes. Setting 510 US hospitals from the claims based Premier Perspective database for 2006-12. Participants 872 416 patients who had total hip or knee arthroplasty. Intervention Perioperative intravenous tranexamic acid use by dose categories (none, ≤1000 mg, 2000 mg, and ≥3000 mg). Main outcome measures Allogeneic or autologous transfusion, thromboembolic complications (pulmonary embolism, deep venous thrombosis), acute renal failure, and combined complications (thromboembolic complications, acute renal failure, cerebrovascular events, myocardial infarction, in-hospital mortality). Results While comparable regarding average age and comorbidity index, patients receiving tranexamic acid (versus those who did not) showed lower rates of allogeneic or autologous transfusion (7.7% v 20.1%), thromboembolic complications (0.6% v 0.8%), acute renal failure (1.2% v 1.6%), and combined complications (1.9% v 2.6%); all Ptranexamic acid dose categories (versus no tranexamic acid use) were associated with significantly (PTranexamic acid was effective in reducing the need for blood transfusions while not increasing the risk of complications, including thromboembolic events and renal failure. Thus our data provide incremental evidence of the potential effectiveness and safety of tranexamic acid in patients requiring orthopedic surgery. PMID:25116268

    The profuse dissemination and utilisation of solar PV technology in the world is indispensable, especially in this era of climate change. However, in the African continent, between 1960 and 2007 Kenya and Zimbabwe were among countries with the highest PV dissemination, while Ghana was among countries with the least disseminations. Analysing empirical data through the lens of the Social Construction of Technology (SCOT) theory, the article aims to uncover the drivers underpinning the disparate dissemination trends of PV in the three countries within the stated period and to tease out lessons apropos replicating the successes within Kenya and Zimbabwe in Ghana. SCOT theory is chosen because it provides an excellent framework for analysing the social shaping of PV's development and diffusion processes in these countries. This theory posits that the shape and meanings of a technology do not reside in it, but are acquired through the heterogeneity of social interactions. Findings in the paper reveal that a gamut of socio-economic and political antecedents informed the varied dissemination outcomes of the technology in these countries. Premised on these findings, the paper recommends critical steps, which Ghana needs to undertake to enhance the replication of the Kenyan and Zimbabwean PV success stories. - Highlights: ► I examined the disparate disseminations of PV in Kenya, Zimbabwe and Ghana. ► Kenya's PV market successes not down to private sector alone. ► Varied antecedents underpin the dissimilar disseminations of PV in these countries. ► Replication of Kenya and Zimbabwe success stories in Ghana demands certain factors.

    Background There are limited published data on the characteristics of blood transfusion recipients in sub-Saharan Africa. This study describes the demographic characteristics of blood transfusion recipients and patterns of blood and blood component use in Zimbabwe. Materials and methods Data on the characteristics of the blood transfusion recipients (age, sex, blood group), blood components received (type, quantity), discharge diagnoses and outcomes following transfusion (discharge status, duration of stay in hospital), were retrospectively collected from four major hospitals for the period from January 1, 2012 to December 31, 2012. Diagnoses were grouped into broad categories according to the disease headings of the International Classification of Diseases (ICD-10). Surgical procedures were grouped into broad categories according to organ system using ICD-9. Results Most of the 1,793 transfusion recipients studied were female (63.2%) and in the reproductive age group, i.e. 15–49 years (65.3%). The median age of the recipients was 33 years (range, 0–93). The majority of these recipients (n=1,642; 91.6%) received a red blood cell transfusion. The majority of the patients were diagnosed with conditions related to pregnancy and childbirth (22.3%), and diseases of blood and blood-forming organs (17.7%). The median time spent in hospital was 8 days (range, 0–214) and in-hospital mortality was 15.4%. Discussion Our sample of blood transfusion recipients were fairly young and most of them received red blood cell transfusions. The majority of patients in the reproductive age group received blood transfusions for pregnancy and childbirth-related diagnoses. PMID:26192782

    The purpose of our study is to compare oncologic and functional outcomes of p16-positive oropharyngeal squamous cell carcinoma (OPSCC) patients, in the presence and absence of planned radiation to the primary bed following transoral surgery (TOS), stratified by T-classification. Retrospective cohort study of 261, T1-T4, consecutively TOS-treated OPSCC patients. At a median follow-up of 61months, local recurrence (LR) occurred in 6 (2.3%)patients (3 each in T1-T2 and T3-T4 groups), of which 5 had tumors in the tongue base and one in the tonsil. Of patients not receiving planned primary bed radiation, LR occurred in 3% of T1-T2s versus 17% of T3-T4s. In patients with T1-T2 tumors, Absolute Risk Reduction of LR with primary bed radiation was 3.26% (95% CI: -0.37%, 7%); Number Needed to Treat to prevent one LR was 31 (95% CI: 14.5, 271). Absolute Risk Increase for gastrostomy-tube with primary bed radiation was 34.4% (95% CI: 24%, 45%); Number Needed to Harm was 3 (95% CI: 2.2, 4.2), i.e., for every three patients with T1-T2 tumors receiving primary bed radiation, one had a gastrostomy-tube. Elimination of primary bed radiation in margin-negative resected, T1-T2 p16-positive OPSCC was not associated with significant compromise of local control, and correlated with superior swallowing preservation, assessed using gastrostomy rate as a surrogate. Lack of primary bed radiation in T3-T4 tumors associated with significantly increased LR rates. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Tourette syndrome (TS) is a neuropsychiatric disorder presenting with motor and/or sonic tics associated with frontostriatal dysfunction. This study provided pilot data of the neuropsychological safety of bilateral thalamic deep brain stimulation (DBS) to treat medication-refractory TS in adults. This study used a repeated-measures design with pretest and 3-month follow-up from start of continuous bilateral DBS. Five male patients underwent DBS surgery for medically refractory TS. Repeated-measures ANOVA was used to evaluate for any change in neuropsychological test scores, employing a false discovery rate. Outcome measures included 14 neuropsychological tests assessing psychomotor speed, attention, memory, language, visuoconstructional, and executive functions, as well as subjective mood ratings of depression and anxiety. Average age was 28.2 years (SD = 7.5) with 12-17 years of education. Participants were disabled by tics, with a tic frequency of 50-80 per minute before surgery. At baseline, subjects' cognitive function was generally average, although mild deficits in sequencing and verbal fluency were present, as were clinically mild obsessive-compulsive symptoms. At 3 months of continuous DBS (5 months after implantation), 3 of 5 participants had clinical reductions in motor and sonic tics. Cognitive scores generally remained stable, but declines of moderate to large effect size (Cohen's d > 0.6) in verbal fluency, visual immediate memory, and reaction time were observed. Fewer symptoms of depression and anxiety, as well as fewer obsessions and compulsions, were reported after 3 months of continuous high-frequency DBS. Bilateral centromedian-parafascicular thalamic DBS for medically refractory TS shows promise for treatment of medically refractory TS without marked neuropsychological morbidity. Symptoms of depression and anxiety improved. © 2014 International Neuromodulation Society.

  17. Understanding postoperative fatigue.

    1978-07-01

    Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

    1993-09-01

    Questions persist about the management of postoperative chylothorax in infants and children. Our experience with postoperative chylothorax over the most recent decade (1980 to 1990) has been reviewed. The type and amount of drainage, data from cardiac catheterization and echocardiography, operative decisions and details, and eventual outcomes have been cataloged. All patients were initially treated with total gut rest, with operation reserved for unabated drainage. Chylothorax developed postoperatively in 15 infants and 11 children (18 with a cardiac procedure and 8 with a noncardiac procedure). The average age was 3.1 years. Spontaneous cessation and cure occurred in 19 (73.1%) of these 26 patients, with an average drainage duration of 11.9 days (range, 4 to 30 days). Those for whom operation was chosen drained preoperatively for an average of 29.2 days (range, 25 to 40 days). There were no deaths in either group. Complications were lymphopenia (2 patients) and fungal sepsis (1 patient). The amount of drainage per day was not significantly different between patients treated operatively and those treated nonoperatively. Failure of nonoperative management was associated with venous hypertension from increased right-sided cardiac pressures or central venous thrombosis (p < 0.05, Fisher's exact test). Presumably this increased pressure is transmitted to the lymphatic system. These patients should be identified early and considered for thoracic duct suture or pleuroperitoneal shunting.

    Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

    Symptomatic vaginal discharge is a common gynecological condition managed syndromically in most developing countries. In Zimbabwe, women presenting with symptomatic vaginal discharge are treated with empirical regimens that commonly cover both sexually transmitted infections (STI) and reproductive tract infections, typically including a combination of an intramuscular injection of kanamycin, and oral doxycycline and metronidazole regimens. This study was conducted to determine the current etiology of symptomatic vaginal discharge and assess adequacy of current syndromic management guidelines. We enrolled 200 women with symptomatic vaginal discharge presenting at 6 STI clinics in Zimbabwe. Microscopy was used to detect bacterial vaginosis and yeast infection. Nucleic acid amplifications tests were used to detect Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis and Mycoplasma genitalium. In addition, serologic testing was performed to detect HIV infection. Of the 200 women, 146 (73%) had an etiology detected, including bacterial vaginosis (24.7%); N. gonorrhoeae (24.0%); yeast infection (20.7%); T. vaginalis (19.0%); C. trachomatis (14.0%) and M. genitalium (7.0%). Among women with STIs (N=90), 62 (68.9%) had a single infection, 18 (20.0%) had a dual infection and 10 (11.1%) had three infections.Of 158 women who consented to HIV testing, 64 (40.5%) were HIV infected.The syndromic management regimen covered 115 (57.5%) of the women in the sample who had gonorrhea, chlamydia, M. genitalium, or bacterial vaginosis, while 85 (42.5%) of women were treated without such diagnosis. Among women presenting with symptomatic vaginal discharge, bacterial vaginosis was the most common etiology and gonorrhea was the most frequently detected STI. The current syndromic management algorithm is suboptimal for coverage of women presenting with symptomatic vaginal discharge; addition of point of care testing could compliment the effectiveness of the syndromic approach.

  8. Brand equity and willingness to pay for condoms in Zimbabwe.

    Zimbabwe suffers from one of the greatest burdens of HIV/AIDS in the world that has been compounded by social and economic instability in the past decade. However, from 2001 to 2009 HIV prevalence among 15-49 year olds declined from 26% to approximately 14%. Behavior change and condom use may in part explain this decline.PSI-Zimbabwe socially markets the Protector Plus (P+) branded line of condoms. When Zimbabwe converted to a dollar-based economy in 2009, the price of condoms was greatly increased and new marketing efforts were undertaken. This paper evaluates the role of condom marketing, a multi-dimensional scale of brand peceptions (brand equity), and price in condom use behavior. We randomly sampled sexually active men age 15-49 from 3 groups - current P+ users, former users, and free condom users. We compared their brand equity and willingness to pay based on survey results. We estimated multivariable logistic regression models to compare the 3 groups. We found that the brand equity scale was positive correlated with willingness to pay and with condom use. Former users also indicated a high willingness to pay for condoms. We found differences in brand equity between the 3 groups, with current P+ users having the highest P+ brand equity. As observed in previous studies, higher brand equity was associated with more of the targeted health behavior, in this case and more consistent condom use. Zimbabwe men have highly positive brand perceptions of P+. There is an opportunity to grow the total condom market in Zimbabwe by increasing brand equity across user groups. Some former users may resume using condoms through more effective marketing. Some free users may be willing to pay for condoms. Achieving these objectives will expand the total condom market and reduce HIV risk behaviors.

    Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

  11. Education policy and gender in Zimbabwe.

    Gordon, R

    1994-01-01

    It is concluded that equality for women in education, which was a state aim in 1980, is no longer a state concern in Zimbabwe. It is argued that protection of the patriarchal order has been the operating principle of both colonial and post-colonial periods, and education is used to maintain the gender imbalance. Black women under colonialism were subjected to both sexism and racism. The socioeconomic order was maintained by ensuring that Blacks remained uneducated and unskilled. Colonial policy was race specific. Education was free and compulsory for Whites only. Black parents paid fees for a son's education. Post colonialism and in 1971, only 43.5% of Black children were enrolled in school, of which 3.9% were in secondary school. Only 19 girls with at the highest level in school. School curriculum was gender based, which meant girls were taught cooking and typing. During independence, education policy was instituted, and education was considered as a human right and gender neutral. Tuition fees in primary grades were eliminated, and education was expanded. However, changes after independence did not result in equal advantage for girls. By 1985-91, girls had lower enrollments at all grade levels. The widest gaps in enrollment were at the highest levels. School curriculum changed very little, and girls were directed to the "feminine" courses of study. Girls performed poorly in math and sciences. Girls were underenrolled in technical and vocational institutions. After 1989, structural adjustment programs negatively impacted on women. There was reduced access to employment, limited access to services, and increased demands on women's time in order to compensate for gaps created by cuts in services. New changes in education policy are expected to negatively impact on girl's education. Fees for primary school were reintroduced in urban areas, and secondary school fees were increased. The government dropped the requirement of certification for technical and commercial

    There is little evidence to date of the potential impact of vegetable gardens on people living with HIV (PLHIV), who often suffer from social and economic losses due to the disease. From 2008 through 2011, Action Contre la Faim France (ACF) implemented a project in Chipinge District, eastern Zimbabwe, providing low-input vegetable gardens (LIGs) to households of PLHIV. Program partners included Médecins du Monde, which provided medical support, and Zimbabwe's Agricultural Extension Service, which supported vegetable cultivation. A survey conducted at the end of the program found LIG participants to have higher Food Consumption Scores (FCS) and Household Dietary Diversity Scores (HDDS) relative to comparator households of PLHIV receiving other support programs. This study assessed the incremental cost-effectiveness of LIGs to improve FCS and HDDS of PLHIV compared to other support programs. This analysis used an activity-based cost model, and combined ACF accounting data with estimates of partner and beneficiary costs derived using an ingredients approach to build an estimate of total program resource use. A societal perspective was adopted to encompass costs to beneficiary households, including their opportunity costs and an estimate of their income earned from vegetable sales. Qualitative methods were used to assess program benefits to beneficiary households. Effectiveness data was taken from a previously-conducted survey. Providing LIGs to PLHIV cost an additional 8,299 EUR per household with adequate FCS and 12,456 EUR per household with HDDS in the upper tertile, relative to comparator households of PLHIV receiving other support programs. Beneficiaries cited multiple tangible and intangible benefits from LIGs, and over 80% of gardens observed were still functioning more than one year after the program had finished. Cost outcomes were 20-30 times Zimbabwe's per capita GDP, and unlikely to be affordable within government services. This analysis concludes that

It contributes to relevant literature by filling gaps in the research on NPM in Zimbabwe The paper provides policy recommendations necessary for addressing public sector reforms in developing economies particularly in African countries that have a history of political instability.

  19. The political economy of power generation in Zimbabwe since 1980

    This article presents a historical analysis of the power generation choices in Zimbabwe since independence in 1980; their causes and consequences. In the early 1980s, the electricity supply choices of the country were dictated by a policy of self-sufficiency, and least-cost supply options (e.g. imports and hydropower) were rejected at a not negligible economic cost. At the end of the 1980s, a new political environment and pressures from the World Bank prompted substantial changes towards least-cost alternatives. In the early 1990s, security of supply motives still played an important role and financial constraints were severe. At present, however, there is little evidence that imported power is still as cheap a source of electricity as it was about 15 years ago. This situation together with the ongoing trend towards higher discount rates imply that thermal power, in particular coal-fired power, will dominate future electricity supply investments in Zimbabwe.

    With the increase in the use of radiation technologies, each country now has a potential risk from nuclear related offenses or malicious use of radioactive material. Despite the major advancements women have made in becoming a significant part of the workforce in all the other fields, women in the field of Nuclear Security are underrepresented in Zimbabwe. Nuclear security contributes to global security and there are a number of things that constitute this field. In the past 10 years, in developing countries, a few women have been taking part in Nuclear Security activities at Major Public events. Less than 1% of women in Zimbabwe are employed and take part in Nuclear Security related work. This study provides the trend in statistics of women employed in the field of Nuclear Security in Zimbabwe and it has identified possible factors why women are underrepresented in that field. It shows the trend of women taking part in Nuclear Security related activities for the past 10 years. Women’s experiences of employment and career development in nuclear security were studied. The factors which hinder or support the career development of women employees in Nuclear Security or related work were identified. Practices which encourage and support women’s involvement in Nuclear Security were explored. A statistical analysis of local authority employment, using the Ministry of Labour, census of women in science and nuclear security related studies in the Population of Zimbabwe, and other relevant sources was carried out. This was to describe the wider context of women’s employment in Nuclear Security. A self-completion questionnaire to get information on personal attributes, age and preferred career paths for women was used. Solutions to the trend are suggested in the study. (author)

  1. Prospects for tobacco control in Zimbabwe: a historical perspective.

    Woelk, G; Mtisi, S; Vaughan, J P

    2001-09-01

    Using a historical and political economy perspective, this paper explores the prospects for tobacco control in Zimbabwe, the world's sixth largest producer and third largest tobacco exporter. Tobacco production, which first began in the former Rhodesia in the early 1900s, is closely associated with colonial history and land occupation by white settlers. The Zimbabwe (formerly Rhodesia) Tobacco Association was formed in 1928 and soon became a powerful political force. Although land redistribution has always been a central issue, it was not adequately addressed after independence in 1980, largely due to the need for Zimbabwe to gain foreign currency and safeguard employment. However, by the mid-1990s political pressures forced the government to confront the mainly white, commercial farmers with a new land acquisition policy, but intense national and international lobbying prevented its implementation. With advent of global economic changes, and following the start of a structural adjustment programme in 1991, manufacturing began to decline and the government relied even more on the earnings from tobacco exports. Thus strengthening tobacco control policies has always had a low national and public health priority. Recent illegal occupation of predominantly white owned farms, under the guise of implementing the former land redistribution policy, was politically motivated as the government faced its first major challenge at the general elections in June 2000. It remains unclear whether this will lead to long term reductions in tobacco production, although future global declines in demand could weaken the tobacco lobby. However, since Zimbabwe is only a minor consumer of tobacco, a unique opportunity does exist to develop controls on domestic cigarette consumption. To achieve this the isolated ministry of health would need considerable support from international agencies, such as the World Health Organisation and World Bank.

    Cognitive dysfunctions are relatively common in postoperative and critically ill patients. This complication not only compromises recovery after surgery, but, if persistent, it minimizes and compromises surgery itself. Risk factors of postoperative cognitive disorders can be divided into age and comorbidity dependent, and those related to anesthesia and surgery. Cardiovascular, orthopedic and urologic surgery carries high risk of postoperative cognitive dysfunction. It can also occur in other types of surgical treatment, especially in elderly. Among risk factors of cognitive disorders, associated with comorbidity, underlying psychiatric and neurological disorders, substance abuse and conditions with elevation of intracranial pressure are in the first place in postoperative patients. Preoperative and perioperative predisposing conditions for cognitive dysfunction and their incidence were described in our paper. These are: geriatric patients, patients with substance abuse, preexisting psychiatric or cognitive disorders, neurologic disease with high intracranial pressure, cerebrovascular insufficiency, epilepsia, preeclampsia, acute intermittent porphyria, operation type, brain hypoxia, changes in blood glucose level, electrolyte imbalance, anesthetic agents, adjuvant medication and intraoperative awareness. For each of these factors, evaluation, prevention and treatment strategies were suggested, with special regard on anesthetic technique.

    1994-01-01

    In Zimbabwe, where over 70,000 illegal abortions are performed each year and complications from clandestine abortion are a leading cause of maternal mortality, the abortion law debate has been re-opened. Under the present law, abortion is legal only to save the life of the mother and women who undergo illegal abortion face strict criminal sanctions. Timothy Stamps, the Minister of Health and Child Welfare, has stated, "The first rights of a child are to be desired, to be wanted, and to be planned." Dr. Illiff, of the University of Zimbabwe's Department of Obstetrics and Gynecology, has noted, "We cannot stop abortion. The choice is how safe it is." Illiff pointed out that urban Zimbabwe women run a 262 times greater risk of dying of abortion complications than their counterparts in the UK where abortion is legal. As the Women's Action Group has observed, men have dominated the current debate on abortion. The group has issued an appeal to women to enter into this debate that concerns their bodies to ensure that another law is not imposed on them. The group's appeal for action states: "We as Women's Action Group believe that every woman should decide what's right and what's wrong in her life. She and only she should be the master of her destiny. Her voice should be heard louder than anyone else's."

    Full Text Available Agricultural products, especially cereal grains, serve as staple foods in sub-Saharan Africa. However, climatic conditions in this region can lead to contamination of these commodities by moulds, with subsequent production of mycotoxins posing health risks to both humans and animals. There is limited documentation on the occurrence of mycotoxins in sub-Saharan African countries, leading to the exposure of their populations to a wide variety of mycotoxins through consumption of contaminated foods. This review aims at highlighting the current status of mycotoxin contamination of food products in Zimbabwe and recommended strategies of reducing this problem. Zimbabwe is one of the African countries with very little information with regards to mycotoxin contamination of its food commodities, both on the market and at household levels. Even though evidence of multitoxin occurrence in some food commodities such as maize and other staple foods exist, available published research focuses only on Aspergillus and Fusarium mycotoxins, namely aflatoxins, deoxynivalenol (DON, trichothecenes, fumonisins, and zearalenone (ZEA. Occurrence of mycotoxins in the food chain has been mainly associated with poor agricultural practices. Analysis of mycotoxins has been done mainly using chromatographic and immunological methods. Zimbabwe has adopted European standards, but the legislation is quite flexible, with testing for mycotoxin contamination in food commodities being done voluntarily or upon request. Therefore, the country needs to tighten its legislation as well as adopt stricter standards that will improve the food safety and security of the masses.

    There is increasing interest in Zimbabwe in the use of renewable energy sources as a means of meeting the country's energy requirements. Biomass provides 47% of the gross energy consumption in Zimbabwe. Energy can be derived from various forms of biomass using various available conversion technologies. Crop residues constitute a large part of the biomass available from the country's agriculture-based economy. The potential for energy production of crop residues is examined using data such as estimates of the quantities of the residues and their energy content. The major crops considered are maize, sugarcane, cotton, soyabeans, groundnuts, wheat, sorghum, fruits and forestry plantations. Quantities of residues are estimated from crop yields by using conversion coefficients for the various crops. Long-term crop yields data from 1970 to 1999 were used. Total annual residue yields for crops, fruits and forestry plantations are 7.805 Mt, 378 kt and 3.05 Mt, respectively. The crops, fruits and forestry residues have energy potential of 81.5, 4.9 and 44.3 PJ per year, respectively. This represents about 44% of the gross energy consumption in Zimbabwe. The need to balance use of crop residues for both energy purposes and other purposes such as animal feeding and soil fertility improvement is also highlighted. (author)

  9. Towards improvement of ethics in the public sector in Zimbabwe

    2015-03-01

    Full Text Available In Zimbabwe reports of abuse of public office have manifested in various forms resulting in public outcry; poor service delivery, and government losing millions of dollars. This study aims to undertake a reflective inquiry on the ethical conduct in the Zimbabwean public sector through content and process analysis in order to provide intervention mechanisms to the problem. Statistical analysis of corruption level is made to benefit the study. Results indicated some legislative gaps and an incapacitated Anti-Corruption Commission which has been unable to execute its mandate fully. Most senior public officials and politicians appear to have too much power and authority with no checks and balances in place. Practical implications of the widespread unethical practices call for the government to plug the glaring legislative gaps; take stern measures against offenders; empowering the Anti-Corruption Commission; term limits for senior public officials as well as for political appointments; and motivating political will to uphold ethical leadership. The recommendations will open a window for the Zimbabwean government and administrators to view how some advanced economies have propped up ethical behaviour in the public sector. It is the way to go for ailing economies like Zimbabwe. The paper demonstrated the importance of ethical awareness in another political and economic setting-Zimbabwe.

    Full Text Available The purpose of the article is to trace the development of student unionism in Zimbabwe.On the basis of a discussion of the nature of the university, the article argues that becausethe university environment tolerates and promotes academic freedom and liberal values, itprovides an environment conducive to critical thought and oppositional politics, while theuniversity quite often itself becomes the target for student attack. Student representationduring the pre-independence period in Zimbabwe sought to engage the institution in itseffort to re-order society at a time of racial struggle and class conflict. After independence,student representation was in support of government efforts to create a better Zimbabweand to consolidate the gains of independence. However, after the first decade ofindependence, the relationship between students and government soured due to students’opposition to the one-party system as well as the University of Zimbabwe AmendmentBill, among other issues. This article thus documents and analyses the relationship betweenstudents and government with reference to three periods and two key moments: the 1973protests against racial discrimination in the pre-independence phase and the post-1990developments in Zimbabwean national and university politics.

    This cost-effectiveness study analyzes the cost per quality-adjusted life year (QALY) gained in a randomized controlled trial that tested school support as a structural intervention to prevent HIV risk factors among Zimbabwe orphan girl adolescents. The intervention significantly reduced early marriage, increased years of schooling completed, and increased health-related quality of life. By reducing early marriage, the literature suggests the intervention reduced HIV infection. The intervention yielded an estimated US$1,472 in societal benefits and an estimated gain of 0.36 QALYs per orphan supported. It cost an estimated US$6/QALY gained, about 1 % of annual per capita income in Zimbabwe. That is well below the maximum price that the World Health Organization (WHO) Commission on Macroeconomics and Health recommends paying for health gains in low and middle income countries. About half the girls in the intervention condition were boarded when they reached high school. For non-boarders, the intervention's financial benefits exceeded its costs, yielding an estimated net cost savings of $502 per pupil. Without boarding, the intervention would yield net savings even if it were 34 % less effective in replication. Boarding was not cost-effective. It cost an additional $1,234 per girl boarded (over the 3 years of the study, discounted to present value at a 3 % discount rate) but had no effect on any of the outcome measures relative to girls in the treatment group who did not board. For girls who did not board, the average cost of approximately 3 years of school support was US$973.

    Cervical cancer is the commonest cancer amongst African women, and yet preventative services are often inadequate. The purpose of the study was to assess the safety, acceptability and feasibility of visual inspection with acetic acid and cervicography (VIAC) followed by cryotherapy or a loop electrical excision procedure (LEEP) at a single visit for prevention of cancer of the cervix. The United Bulawayo Hospital, Zimbabwe. The study was descriptive, using retrospective data extracted from electronic medical records of women attending the VIAC clinic. Over 24 months 4641 women visited the clinic and were screened for cervical cancer using VIAC. Cryotherapy or LEEP was offered immediately to those that screened positive. Treated women were followed up at three months and one year. The rate of positive results on VIAC testing was 10.8%. Of those who were eligible, 17.0% received immediate cryotherapy, 44.1% received immediate LEEP, 1.9% delayed treatment, and 37.0% were referred to a gynaecologist. No major complications were recorded after cryotherapy or LEEP. Amongst those treated 99.5% expressed satisfaction with their experience. Only 3.2% of those treated at the clinic had a positive result on VIAC one year later. The service was shown to be feasible to sustain over time with the necessary consumables. There were no service-related treatment postponements and the clinic staff and facility were able to meet the demand for the service. A single-visit approach using VIAC, followed by cryotherapy or LEEP, proved to be safe, acceptable and feasible in an urban African setting in Bulawayo, Zimbabwe. Outcomes a year later suggested that treatment had been effective.

    2013-01-01

    Impairment in cognitive function is found in a significant subset of individuals undergoing bariatric surgery, and recent work shows this impairment is associated with smaller postoperative weight loss. Reduced cognitive function could contribute to poorer adherence to postoperative guidelines, although this has not been previously examined. The present study examined the relationship between cognitive function and adherence to bariatric postoperative guidelines. We expected that higher cognitive function would be associated with better adherence to postoperative guidelines. Thirty-seven bariatric surgery patients completed cognitive testing and a self-report measure of adherence to postoperative bariatric guidelines during their 4- to 6-week postoperative appointment. Strong correlations were observed between adherence to postoperative guidelines and cognitive indices of attention, executive function, and memory. Results show that cognitive performance is strongly associated with adherence to postoperative guidelines shortly after bariatric surgery. Further work is needed to clarify whether this relationship is present at later postoperative stages and the degree to which this relationship mediates postoperative weight loss outcomes.

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. Copyright © 2015 Elsevier Inc.

    It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalcemia in patients who underwent thyroidectomy for Graves' disease. An institutional review board-approved database was created of all patients who underwent thyroidectomy from 1998 to 2009 at the Johns Hopkins Hospital. There were a total of 68 patients with Graves' disease who underwent surgery. Fifty-five patients who underwent total thyroidectomy were randomly selected and served as control subjects. An analysis was conducted that examined potential covariates for postoperative hypocalcemia, including age, gender, ethnicity, preoperative alkaline phosphatase level, size of goiter, whether parathyroid tissue or glands were present in the specimen, and the reason the patient underwent surgery. Specific outcomes examined were calcium levels on postoperative day 1, whether or not patients experienced symptoms of hypocalcemia, whether or not Rocaltrol was required, the number of calcium tablets prescribed upon discharge, whether or not postoperative tetany occurred, and calcium levels 1 month after discharge. Each outcome was analyzed using a logistic regression. Graves' disease patients had a significantly (p-value Graves' disease and no patient in the control group were readmitted with tetany (p = 0.033). There was a trend, though not significant, toward patients with Graves' disease having a higher prevalence of hypocalcemia the day after thyroidectomy and 1 month later. Patients with Graves' disease are more likely to require increased dosages of calcium as well as experience tetany postoperatively than patients undergoing total thyroidectomy for other indications. This suggests that

    Full Text Available The Heart Institute of the University of São Paulo, Medical School is a referral center for the treatment of congenital heart diseases of neonates and infants. In the recent years, the excellent surgical results obtained in our institution may be in part due to modern anesthetic care and to postoperative care based on well-structured protocols. The purpose of this article is to review unique aspects of neonate cardiovascular physiology, the impact of extracorporeal circulation on postoperative evolution, and the prescription for pharmacological support of acute cardiac dysfunction based on our cardiac unit protocols. The main causes of low cardiac output after surgical correction of heart congenital disease are reviewed, and methods of treatment and support are proposed as derived from the relevant literature and our protocols.

    Despite the availability of high-quality guidelines and advanced pain management techniques acute postoperative pain management is still far from being satisfactory. The QUIPS (Quality Improvement in Postoperative Pain Management) project aims to improve treatment quality by means of standardised data acquisition, analysis of quality and process indicators, and feedback and benchmarking. During a pilot phase funded by the German Ministry of Health (BMG), a total of 12,389 data sets were collected from six participating hospitals. Outcome improved in four of the six hospitals. Process indicators, such as routine pain documentation, were only poorly correlated with outcomes. To date, more than 130 German hospitals use QUIPS as a routine quality management tool. An EC-funded parallel project disseminates the concept internationally. QUIPS demonstrates that patient-reported outcomes in postoperative pain management can be benchmarked in routine clinical practice. Quality improvement initiatives should use outcome instead of structural and process parameters. The concept is transferable to other fields of medicine. Copyright © 2011.

    There have been numerous global calls to action to utilize human resources information systems (HRIS) to improve the availability and quality of data for strengthening the regulation and deployment of health workers. However, with no normative guidance in existence, the development of HRIS has been inconsistent and lacking in standardization, hindering the availability and use of data for health workforce planning and decision making (Riley et al., 2012). CDC and WHO partnered with the Ministry of Health in several countries to conduct HRIS functional requirements analyses and establish a Minimum Data Set (MDS) of elements essential for a global standard HRIS. As a next step, CDC advanced a study to examine the alignment of one of the HRIS it supports (in Zimbabwe) against this MDS. For this study, we created a new data collection and analysis tool to assess the extent to which Zimbabwe's CDC-supported HRIS was aligned with the WHO MDS. We performed systematic "gap analyses" in order to make prioritized recommendations for addressing the gaps, with the aim of improving the availability and quality of data on Zimbabwe's health workforce. The majority of the data elements outlined in the WHO MDS were present in the ZHRIS databases, though they were found to be missing various applicable elements. The lack of certain elements could impede functions such as health worker credential verification or equitable in-service training allocation. While the HRIS MDS treats all elements equally, our assessment revealed that not all the elements have equal significance when it comes to data utilization. Further, some of the HRIS MDS elements exceeded the current needs of regulatory bodies and the Ministry of Health and Child Care (MOHCC) in Zimbabwe. The preliminary findings of this study helped inspire the development of a more recent HRH Registry MDS subset, which is a shorter list of priority data elements recommended as a global standard for HRIS.

    Maternal nutritional status before and during pregnancy is an important contributor to pregnancy outcomes and early child health. The aim of this study was to describe the preconceptional nutritional status and dietary intake during pregnancy in high-risk women from South Africa and Zimbabwe. This is a prospective observational study, nested to the CAP trial. Anthropometric measurements before and during pregnancy and dietary intake using 24-h recall during pregnancy were assessed. The Intake Distribution Estimation software (PC-SIDE) was used to evaluate nutrient intake adequacy taking the Estimated Average Requirement (EAR) as a cut-off point. Three hundred twelve women who had pre-eclampsia in their last pregnancy and delivered in hospitals from South Africa and Zimbabwe were assessed. 73.7 and 60.2% women in South Africa and Zimbabwe, respectively started their pregnancy with BMI above normal (BMI ≥ 25) whereas the prevalence of underweight was virtually non-existent. The majority of women had inadequate intakes of micronutrients. Considering food and beverage intake only, none of the micronutrients measured achieved the estimated average requirement. Around 60% of pregnant women reported taking folic acid or iron supplements in South Africa, but almost none did so in Zimbabwe. We found a high prevalence of overweight and obesity and high micronutrient intake inadequacy in pregnant women who had the previous pregnancy complicated with pre-eclampsia. The obesity figures and micronutrient inadequacy are issues of concern that need to be addressed. Pregnant women have regular contacts with the health system; these opportunities could be used to improve diet and nutrition. PACTR201105000267371 . Registered 06 December 2010.

    Full Text Available Treatment of the elderly is becoming increasingly common problem and is of interest, because in the future this phenomenon will affect most of us. For many years, he observed in different countries increasingly rapid aging of the population, including in Poland. The operation in such a patient poses a high risk of complications and life-threatening conditions. Their age makes in the postoperative period there are many medical problems. Many factors can affect the scope of a different self-care nursing with such a patient.

    Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

    A Work Project, presented as part of the requirements for the Award of a Masters Degree in Economics from the NOVA – School of Business and Economics HIV/AIDS-related stigma and discrimination have been getting more and more attention by researchers and policy-makers. Since stigma has direct impact on the way-of-living of PLHA1 and their decision-making process, it can be an important key in the spread of HIV. Zimbabwe is one of the countries with the highest HIV prevalence rates ...

  9. Risk Factors for Postoperative Fibrinogen Deficiency after Surgical Removal of Intracranial Tumors.

    Directory of Open Access Journals (Sweden)

    Naili Wei

    Full Text Available Higher levels of fibrinogen, a critical element in hemostasis, are associated with increased postoperative survival rates, especially for patients with massive operative blood loss. Fibrinogen deficiency after surgical management of intracranial tumors may result in postoperative intracranial bleeding and severely worsen patient outcomes. However, no previous studies have systematically identified factors associated with postoperative fibrinogen deficiency. In this study, we retrospectively analyzed data from patients who underwent surgical removal of intracranial tumors in Beijing Tiantan Hospital date from 1/1/2013to12/31/2013. The present study found that patients with postoperative fibrinogen deficiency experienced more operative blood loss and a higher rate of postoperative intracranial hematoma, and they were given more blood transfusions, more plasma transfusions, and were administered larger doses of hemocoagulase compared with patients without postoperative fibrinogen deficiency. Likewise, patients with postoperative fibrinogen deficiency had poorer extended Glasgow Outcome Scale (GOSe, longer hospital stays, and greater hospital expenses than patients without postoperative fibrinogen deficiency. Further, we assessed a comprehensive set of risk factors associated with postoperative fibrinogen deficiency via multiple linear regression. We found that body mass index (BMI, the occurrence of postoperative intracranial hematoma, and administration of hemocoagulasewere positively associated with preoperative-to-postoperative plasma fibrinogen consumption; presenting with a malignant tumor was negatively associated with fibrinogen consumption. Contrary to what might be expected, intraoperative blood loss, the need for blood transfusion, and the need for plasma transfusion were not associated with plasma fibrinogen consumption. Considering our findings together, we concluded that postoperative fibrinogen deficiency is closely associated with

  10. Crop diversification and livelihoods of smallholder farmers in Zimbabwe: adaptive management for environmental change.

    This paper demonstrates how crop diversification impacts on two outcomes of climate smart agriculture; increased productivity (legume and cereal crop productivity) and enhanced resilience (household income, food security, and nutrition) in rural Zimbabwe. Using data from over 500 smallholder farmers, we jointly estimate crop diversification and each of the outcome variables within a conditional (recursive) mixed process framework that corrects for selectivity bias arising due to the voluntary nature of crop diversification. We find that crop diversification depends on the land size, farming experience, asset wealth, location, access to agricultural extension services, information on output prices, low transportation costs and general information access. Our results also indicate that an increase in the rate of adoption improves crop productivity, income, food security and nutrition at household level. Overall, our results are indicative of the importance of crop diversification as a viable climate smart agriculture practice that significantly enhances crop productivity and consequently resilience in rural smallholder farming systems. We, therefore, recommend wider adoption of diversified cropping systems notably those currently less diversified for greater adaptation to the ever-changing climate.

  11. Individual resilience as a strategy to counter employment barriers for people with epilepsy in Zimbabwe.

    2017-09-01

    Understanding individual resilience helps to improve employment opportunities of people with epilepsy. This is significant because, in Zimbabwe, as in many other countries in the Global South, people with epilepsy encounter several barriers in a context of less-than-ideal public services. Despite this disadvantage, some people with epilepsy have better employment outcomes for reasons including level of seizure control, social background, employment support services, and individual resilience. This article reports on data from participants (n=8), who were part of a larger study (n=30) on employment experiences of people with epilepsy in Harare. The study used in-depth interviews with the participants, who were all service users and members of the Epilepsy Support Foundation (ESF) in Harare. The eight resilient participants comprised four males and four females aged between 26-48years, who were selected because, unlike the remaining 22 participants, they had overcome chronic unemployment. Seven of the eight participants were employed, while one had recently become unemployed. Views of service providers (n=7) were sought on the experiences of people with epilepsy through a focus group discussion. The service providers included two health workers, three social service workers, and two disability advocacy workers. Data were analysed using NVivo, a computer-assisted qualitative data analysis package. The study found that participants experienced barriers, such as a lack of medical treatment, yet this was important for education and training, lack of finances for training, and negative attitudes at workplaces. Despite these barriers, participants had overcome chronic unemployment due to their individual resilience characterised by: (i) a 'fighting spirit', (ii) being their own advocates, and (iii) having a mastery over, and acceptance of, their epilepsy. The research concluded that, where people with epilepsy faced barriers, as in Zimbabwe, individual resilience acted as

    To evaluate the frequency of pneumothorax after laparoscopic surgery and to identify possible correlations to endometriosis. Retrospective review. Tokyo University Hospital between 2006 and 2013. Four patients among a total of 2814 patients with a postoperative pneumothorax. Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax. We observed 4 (0.14%) cases of postoperative pneumothorax after laparoscopic surgery, all of whom were diagnosed with endometriomas and developed a right-sided pneumothorax. The incidence of postoperative pneumothorax in 1097 patients with endometriomas was 0.36%, which was significantly higher than those without endometriomas. The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery. Copyright © 2015 AAGL. Published by Elsevier Inc.

    2013-12-01

    To determine if there is a relationship between the risk of postoperative complications and the nonclinical hospital characteristics of bed size, ownership structure, relative urbanicity, regional location, teaching status, and area income status. This study involved a secondary analysis of 2006 administrative hospital data from a number of U.S. states. This data, gathered annually by the Agency for Healthcare Research and Quality (AHRQ) via the National Inpatient Sample (NIS) Healthcare Utilization Project (HCUP), was analyzed using probit regressions to measure the effects of several nonclinical hospital categories on seven diagnostic groupings. The study model included postoperative complications as well as additional potentially confounding variables. The results showed mixed outcomes for each of the hospital characteristic groupings. Subdividing these groupings to correspond with the HCUP data analysis allowed a greater understanding of how hospital characteristics' may affect postoperative outcomes. Nonclinical hospital characteristics do affect the various postoperative complications, but they do so inconsistently.

    Evidence from household surveying in December 2005 in Harare and Bulawayo, Zimbabwe, indicates that a wide network of international migrant remitters are ameliorating the economic crisis in Zimbabwe by sending monetary and in-kind transfers to over 50 per cent of urban households. The research combines quantitative measurement of scale and scope, with demographic and qualitative narrative to build a holistic picture of the typography of receiving and non-receiving households. A complex set of interrelated variables helps to explain why some households do and others do not receive income and goods from people who are away, and the economic and social extent of their subsequent benefit from them. Moreover, the mixed methods approach is designed to capture inter-household and likely macroeconomic effects of how households receive their goods and money; and of how they subsequently exchange (if applicable), store and spend it. Evidence emerges of a largely informal, international social welfare system, but one which is not without adverse inter-household effects for some. These include suffering exclusion from markets suffering from inflationary pressures, not least as a result of other people’s remittances. This paper explores the role of remittances, within this internationalised informal welfare system which we can map from our household survey, in reframing vulnerability and marginalization differentially among and between our subject households.

  15. Base line definitions and methodological lessons from Zimbabwe

    The UNEP Greenhouse Gas Abatement Costing Studies carried out under the management of the UNEP Collaborating Centre On Energy and Environment at Risoe National Laboratories in Denmark has placed effort in generating methodological approaches to assessing the cost of abatement activities to reduce CO 2 emissions. These efforts have produced perhaps the most comprehensive set of methodological approaches to defining and assessing the cost of greenhouse gas abatement. Perhaps the most importance aspect of the UNEP study which involved teams of researchers from ten countries is the mix of countries in which the studies were conducted and hence the representation of views and concepts from researchers in these countries particularly those from developing countries namely, Zimbabwe, India, Venezuela, Brazil, Thailand and Senegal. Methodological lessons from Zimbabwe, therefore, would have benefited from the interactions with methodological experiences form the other participating countries. Methodological lessons from the Zimbabwean study can be placed in two categories. One relates to the modelling of tools to analyze economic trends and the various factors studied in order to determine the unit cost of CO 2 abatement. The other is the definition of factors influencing the levels of emissions reducible and those realised under specific economic trends. (au)

  16. Challenges of communicating integrated water resource management in Zimbabwe

    Science.gov (United States)

    Marimbe, Simbiso; Manzungu, Emmanuel

    With the promulgation of the 1998 Water Act the Government of Zimbabwe took a decisive step to reform the country’s water sector, to bring it in line with contemporary socio-political realities obtaining in the country, and in tune with the philosophy of integrated water resources management. Researchers have reported a lack of awareness of the reforms, particularly among the black communities, who were considered not just as one of the target of the reforms, but the beneficiaries. This paper analyses why this has been the case. The paper makes a case for differentiating communication from information dissemination. Information refers to a set of data packaged for delivery to a receiver while communication involves a dialogue. This paper critiques communication strategies used to communicate water reforms in Zimbabwe, applying recent developments in communication theories. The argument in the paper is that there was a failure to communicate although there was some success in dissemination information about the reforms. If the situation is to be reversed then methods that involve audience analysis may have to be used. Such methods tend to be expensive and time consuming--however, there is no substitute to this if integrated water resources management is to be institutionalised among the various stakeholders.

    The World Heritage Site of Great Zimbabwe is one of the most iconic and largest archaeological settlements in Africa. It was the hub of direct and indirect trade which internally connected various areas of southern Africa, and externally linked them with East Africa and the Near and Far East. Archaeologists believe that at its peak, Great Zimbabwe had a fully urban population of 20,000 people concentrated in approximately 2.9 square kilometres (40 percent of 720 ha). This translates to a population density of 6,897, which is comparable with that of some of the most populous regions of the world in the 21st century. Here, we combine archaeological, ethnographic and historical evidence with ecological and statistical modelling to demonstrate that the total population estimate for the site's nearly 800-year occupational duration (CE1000-1800), after factoring in generational succession, is unlikely to have exceeded 10,000 people. This conclusion is strongly firmed up by the absence of megamiddens at the site, the chronological differences between several key areas of the settlement traditionally assumed to be coeval, and the historically documented low populations recorded for the sub-continent between CE1600 and 1950.

  18. Issues and prospects for coal utilization in Zimbabwe's rural households

    1990-01-01

    The increasing shortage of traditional fuels in Zimbabwe has prompted government to consider seriously the use of coal in rural households. In this regard, both government and the privately owned coal industry have begun pilot projects in selected rural areas to initiate the introduction of coal stoves and coal fuels. These efforts by government and the coal industry need to be informed by knowledge of the financial and economic dimensions of coal diffusion to rural economies, the environmental implications of widespread coal use in rural households, and the general acceptability of coal as a fuel to households with a long tradition of free fuels. This paper summarizes the results of a study undertaken to provide such background information. Conducted over six months during 1988, the study included field surveys of four districts in Zimbabwe: Murewa, Shurugwi, Mberengwa, and Mazoe Citrus Estates. All but the Mazoe district are rural settings with severe shortages of fuelwood. Mazoe Citrus Estates is a semi-urban plantation community which has had over twenty years' experience with coal use in households under a company-sponsored programme which supplies both fuels and stoves free of charge

    2013-01-01

    This paper draws on a series of qualitative interviews with 60 people living in economically poor communities of Harare, the capital of Zimbabwe, to provide new insight into the cultural landscape of HIV. While there has been extensive exploration of gender, sexuality, culture and HIV in Zimbabwe, there is a need to revisit these issues given the country's recent political and economic history. These questions have shaped the meanings that have been created around HIV (i.e., notions of HIV-as-death and as being produced by promiscuity) and the gendered mediation of cultural practices (i.e., forms of sexual expression and treatment uptake). Drawing on the accounts from a group directly affected by HIV, we illustrate the persistence of gendered and spiritualised ideas about 'blame', 'transmission' and 'treatment' and the disproportionate burden that still falls on Zimbabwean women. We conclude with an exploration of how everyday understandings of HIV may be shifting and the ways in which marginality, discrimination and stigma may be being challenged by openness, dialogue and attitude change.

    Objective: To identify the causes of postoperative enterocutaneous fistulas and to evaluate the results of conservative and operative treatment including the effectiveness of octreotide in the management of these fistulas. Subjects and Methods: Forty patients with postoperative fistula were studied. Demographic variables, causes and management outcome was observed and recorded. Results: There were 25 males and 15 females with 50% of the patients being in age group of 21-30 years. Emergency surgery for typhoid perforation(45%) and intestinal tuberculosis (30%) were the commonest causes. Ileum and jejunum were the commonest sites of fistulation found in 85% cases. Twenty-one patients were started on conservative treatment with spontaneous closure occurring in 15 (71.4%) patients. Nineteen patients were operated within three days of admission due to generalized peritonitis (73.7%) and local intra-abdominal collections (26.3%). Wound infection was the commonest complication in the operative group. The mortality rate in this series was 7.5%. All the deaths occurred following surgery. Conclusion: Postoperative enterocutaneous fistula has a high morbidity and a significant mortality. Sepsis in the peritoneal cavity is the major cause of mortality. Conservative treatment has a good outcome for these fistulas. The use of octreotide is highly recommended as it definitely converts high output fistulas to low output fistulas. (author)

    Recently, skeletal muscle depletion (sarcopenia) has been reported to influence postoperative outcomes after certain procedures. This study investigated the impact of sarcopenia on postoperative outcomes following pancreaticoduodenectomy (PD). We performed a retrospective study of consecutive patients (n = 219) who underwent PD at our institution between January 2007 and May 2013. Sarcopenia was evaluated using preoperative computed tomography. We evaluated postoperative outcomes and the influence of sarcopenia on short-term outcomes, especially infectious complications. Subsequently, multivariate analysis was used to assess the impact of prognostic factors (including sarcopenia) on postoperative infections. The mortality, major complication, and infectious complication rates for all patients were 1.4%, 16.4%, and 47.0%, respectively. Fifty-five patients met the criteria for sarcopenia. Sarcopenia was significantly associated with a higher incidence of in-hospital mortality (P = 0.004) and infectious complications (P sarcopenia (odds ratio = 3.43; P Sarcopenia is an independent preoperative predictor of infectious complications after PD. Clinical assessment combined with sarcopenia may be helpful for understanding the risk of postoperative outcomes and determining perioperative management strategies.

    In 1992 UNEP-Collaborating Centre on Energy and Environment (UNEP-CCEE), Denmark and Southern Centre for Energy and Environment (SCEE), Zimbabwe, prepared a country report for Zimbabwe on Greenhouse Gas (GHG) Abatement Costing. Abatement technologies for both supply and demand side were identified in order to reduce GHG emission. The present study addresses environmental impacts of the entire energy cycle focusing on coal use in industry and power generation. Zimbabwe has proven coal reserves of more than 700 million tonnes, and the potential of geological coal resources is estimated beyond 30 billion tonnes. The conventional applications of coal include electricity generation, steam traction in railway transport, industrial boilers, tobacco curing and coking. As coal is the major source of energy for Zimbabwe, the present study aims at identification of environmental impacts of the entire coal cycle from mining to end-users of electrical energy. (EG)

    The effectiveness of cryotherapy on joint arthroplasty recovery remains controversial. This systematic review was conducted to assess the effectiveness of cryotherapy in patients after joint arthroplasty. Comprehensive literature searches of several databases including Cochrane Library (2013), MEDLINE (1950-2013), and Embase (1980-2013) were performed. We sought randomised controlled trials that compared the experimental group received any form of cryotherapy with any control group after joint arthroplasty. The main outcomes were postoperative blood loss, adverse events, and pain. Analyses were performed with Revman 5.0. Results were shown as mean differences (MD) and standard deviations or as risk difference and 95 % confidence intervals (CIs). Ten trials comprised 660 total knee arthroplastys and three trials comprised 122 total hip arthroplastys (THAs) met the inclusion criteria. Blood loss was significantly decreased by cryotherapy (MD = -109.68; 95 % CI -210.92 to -8.44; P = 0.03). Cryotherapy did not increase the risk of adverse effect (n.s.). Cryotherapy decreased pain at the second day of postoperative (MD = -1.32; 95 % CI -2.37 to -0.27; P = 0.0003), but did not decreased pain at the first and third day of postoperative (n.s.). Cryotherapy appears effective in these selected patients after joint arthroplasty. The benefits of cryotherapy on blood loss after joint arthroplasty were obvious. However, the subgroup analysis indicated that cryotherapy did not decreased blood loss after THA. Cryotherapy did not increase the risk of adverse effect. Cryotherapy decreased pain at the second day of postoperative, but did not decreased pain at the first and third day of postoperative. II.

    Postoperative CT appearances in 65 cases of chronic subdural hematomas were evaluated in terms of patient's age, preoperative neurological symptoms and CT findings, final outcomes, and so on. All of the cases were treated with trepanation and irrigation. CT appearances were divided into four different types as follows; Type Ia: No abnormal findings in the subdural sapce, Type Ib: The same as above except for a linear high density suggestive of thickened outer membrane, Type II: Persistence subdural fluid collection and widened cortical sulci which indicate underlining brain atrophy, Type III: Remaining hematoma and/or density changes during follow-up period. Although the mean age of the patients in type Ib was higher than those in type Ia and reexpansion of the brain appear to delay in type Ib and preoperative CT in type Ib tended to show mixed density, final outcome in both groups were excellent. Characteristics in type II were that most of cases were in the eighth decade, preceding head injury was unclear, preoperative psychiatric symptoms and disturbance of consciousness were common and postoperative improvement of the symptoms was not satisfactory compared to other types. Aged patients as in type Ib and type II and thick hematomas of over 2 cm depth with mixed or high density tended to show type III postoperatively. All of the nine patients who required reoperation were included in this type. The present study indicates that thick hematomas with sizable mass effect and mixed or high density in the aged must be carefully treated, such as with placement of the subdural drainage or keeping the patient in the Trendelenburg position, to facilitate postoperative reexpansion of the brain.

    Politicians call them the "festering finger," endangering the body of the nation; churchmen say God wants them dead; the courts send them to jail. Zimbabwe has declared that it will not tolerate homosexuality. Gays and lesbians feel persecuted and their rights are undermined. The controversy that was ignited in 1997 when the Zimbabwean government forced the closure of a fair booth by Gays and Lesbians of Zimbabwe at the Zimbabwe International Book Fair continues to echo. At issue are fundamental questions of the scope of human rights protection in Zimbabwe and other African countries (BBC News, 1998). Such issues have sparked endless debates on homosexuality in religion, politics, and other forums. This article seeks to explore the attitudes of both traditional Shona culture and Christian sectors in Zimbabwe. The goal is to find out if the practice is rooted in Shona tradition or if it can be seen as a new phenomenon emanating from Western political and Judeo-Christian influences on Zimbabwe. The article argues that the Zimbabwean attitudes toward homosexuality combine Christian and traditional morality. Finally, the article will discuss how Christian churches and traditional Shona culture come to terms with homosexual practice today.

  17. “All for some”: water inequity in Zambia and Zimbabwe

    Science.gov (United States)

    Robinson, Peter B.

    In southern Africa, gross disparities in access to water are symptomatic of the overall uneven pattern of development. Despite post-independence egalitarian rhetoric, in countries such as Zambia and Zimbabwe inappropriate models (piped house connections in the urban areas, high technology irrigation schemes in the agricultural sector), combined with weak macro-economies and poorly formulated sectoral policies have actually exacerbated the disparities. Zero or very low tariffs have played a major role in this. Although justified as being consistent with water's special status, inadequate tariffs in fact serve to undermine any programme of making water accessible to all. This has led to a narrowing of development options, resulting in exclusivist rather than inclusivist development, and stagnation rather than dynamism. A major part of the explanation for perpetuation of such unsatisfactory outcomes is the existence of political interest groups who benefit from the status quo. The first case study in the paper involves urban water consumers in Zambia, where those with piped water connections seek to continue the culture of low tariffs which is by now deeply embedded. The result is that the water supply authorities (in this case the newly formed, but still politically constrained 'commercialised utilities') are unable even to maintain adequate supplies to the piped customers, let alone extend service to the peri-urban dwellers, 56% of whom do not have access to safe water. The paper outlines some modest, workable principles to achieve universal, affordable access to water in the urban areas, albeit through a mix of service delivery mechanisms. In a second case study of rural productive water in Zimbabwe, the reasons for only 2% of the rural subsistence farming households being involved in formal small-scale irrigation schemes 20 years after independence are explored. Again, a major part of the explanation lies in government pursuing a water delivery model which is not

    Full Text Available Various violations of the human rights of ordinary people and human rights defenders have been reported in Zimbabwe since the late 1980s. It is widely acknowledged that such violations have been perpetrated mostly by the government through its different organs for political and other related reasons. Human rights violations were also easily committed against ordinary people and human rights defenders because there was no Constitution that adequately protected such people's fundamental human rights (including their civil and political rights and their socio-economic rights in Zimbabwe. Given this background, the article discusses the protection of human rights in Zimbabwe, in the light of the Zimbabwe Constitution Amendment Act 20 of 2013 (Zimbabwe Constitution 2013. This is done in order to investigate whether the promotion, protection, enforcement and respect for human rights in Zimbabwe has now improved. To this end, the functions of selected national human rights institutions and other related role-players, namely civil society, the judiciary, the law enforcement organs and the Zimbabwe Human Rights Commission, are briefly discussed first. Secondly, the functions of selected regional and international institutions, namely the Southern African Development Community, the African Union and the United Nations are discussed in relation to the protection of human rights in Zimbabwe. Thereafter, concluding remarks and possible recommendations that could be utilised to combat human rights violations and enhance the protection of human rights in Zimbabwe are provided.

    Over the last two decades both the number and types of civil-society-led organisations involved in addressing HIV and AIDS have increased dramatically. In many cases, the work undertaken is thoughtfully researched, appropriately focused, and as a result produces positive outcomes. Yet questions can be raised about what civil society engagements involve, particularly at a micro level. An important element concerns the role of the arts in efforts to understand and address HIV and AIDS. This article examines ways that insight, analysis, and action around HIV and AIDS have unfolded through the purview of artistic activities undertaken by cultural activists in Harare, Zimbabwe-that is, arts-oriented engagements occurring beyond the boundaries of formally structured organisations. Artistic expressions, which often concern lived experiences, make clear the complex circumstances surrounding HIV and AIDS, and at the same time seek to act upon those circumstances. Understanding and addressing HIV and AIDS requires more than one form of knowledge. Drawing on data from 21 months of ethnographic research in Harare, I examine artistic expressions as legitimate forms of knowledge and as strategies for intervention.

    Until recently there has been little, if any, concern over revamping let alone improving wastewater management system in Zimbabwe's urban areas given the dominance and institutionalised water-borne system. Yet, the current constraints in this system and the immensity of urbanisation in the country begs and compels planners, engineers and systems thinkers to rethink what best can work as a sustainable wastewater system. With particular reference to the ever-expanding Harare metropolitan region, this article provides an evaluative analysis on the potentiality, risks and strategies that can be adopted by Harare and its satellites in addressing the problems of the conventional wastewater management system. The suggested framework of operation is a decentralised domestic wastewater collection and treatment system which however has its own multifarious risks. Using systems dynamics conceptualisation of the potentiality, opportunities, risks and strategies, the paper seeks to model the path and outcomes of this decentralised domestic wastewater collection and treatment system and also suggests a number of policy measures and strategies that the city of Harare and its satellites can adopt.

    The failed back surgery syndrome (FBSS) is one of the most perplexing medical and medicoeconomic problems facing our health system today. In many studies reoperation rates tend to be between 10 and 20%, but as many as 20-45% 3 of patients may have persistent back or radicular pain following what was to have been definitive therapy. The causes for the FBSS are very complex. The Workmen's Compensation system and medicolegal trends toward very high settlements of litigation for injury have provided serious incentive for patients to remain symptomatic. It is difficult to analyze any statistical survey of symptomatic back patients without serious bias from this group of patients. Others suggest that patients with severe psychological problems, drug abuse, and alcoholism are inappropriately selected as surgical candidates. They believe that careful psychological evaluation of patients minimizes FBSS. Even if all extrinsic factors could be eliminated, the problem of failed back surgery would still be a major one. This chapter is based on a review of 300 postoperative lumbar spine multiplanar CT scans performed over a 15-month period. All patients had a complete set of axial images, with sagittal and coronal reformations photographed twice: optimized once for bone definition and once for soft-tissue contrast resolution

    Full Text Available This study is a syntactic analysis of text messages in English language used by University of Zimbabwe students. The study specifically focuses on sentences where there are omissions of pronouns, auxiliary verbs and where contractions occur. The study also analyzes the impact of sociolinguistic variables on the sentence structure of English language in text messages. The fifty respondents’ forwarded two messages each from their sent items on their cell phones to the researcher and to understand the factors triggering the syntactic structures the researcher carried out unstructured interviews. The data collected showed that cell phone texting has indeed been affected by the socio-economic factors and these factors trigger omissions of important elements of English language sentence structure such as ,pronouns, auxiliary verbs and contraction of phrases.

    The importance of main streaming gender issues in development programmes is now recognized by governments and development agents. This paper evaluates the role of gender in smallholder livestock production using Zimbabwe as a case study. It draws on several studies and assesses the gender dimension in terms of access and control, decision making and, division of labour. It is shown that for mainly traditional and historical reasons men continue to dominate livestock production although the situation is gradually changing. Men eclipse women in terms of ownership of more valuable stock, the making of decisions and the control of livestock production. This suggests that gender is important in livestock production and must be considered among other factors. The complexity of the system is noted but more gender disaggregated quantitative data is required if gender is to be effectively mainstreamed in livestock development programmes.

  4. Artisanal Fisheries in Zimbabwe: Options for Effective Management

    Full Text Available The small-scale (artisanal fisheries in Zimbabwe play an important role in income-generation and food security at the household level. This sector has the potential to significantly increase its contribution to household income and food security if more effective fisheries management strategies are put in place. Historically, fisheries management has adopted a centralised “Top-down” approach. This approach has had very limited effectiveness. Over the last decade, efforts have been made to implement co-management in the fisheries sector. Several factors have hampered the success of fisheries co-management in the artisanal fishery. These factors have been institutional, ecological, human and financial. This paper discusses these factors and proposes possible solutions. A more innovative and effective fisheries management approach is also proposed.

    A socioculturally appropriate health risk behavior instrument, modeled after the U.S. Centers for Disease Control and Prevention's Youth Risk Behavior Survey (YRBS), was administered to 717 secondary school students in a rural area of Zimbabwe. Comparisons of risk behaviors by gender and school grade were made using univariate procedures and multiple logistic regression. Males were significantly more likely than females to have had sexual intercourse (odds ratio = 5.02, p < .0001) and to report drug use behaviors. Males also were significantly more likely to report early initiation (by age 13 years) of alcohol use, cigarette smoking, and marijuana use. School site violence and drug use behaviors also were prevalent in this sample. An interaction between gender and grade was evident for some behaviors. Additional research may further the understanding of these risk behaviors and facilitate development of effective, culturally relevant risk reduction programs.

    Full Text Available Tsetse (Glossina sensu stricto are cyclical vectors of human and animal trypanosomoses, that are presently targeted by the Pan African Tsetse and Trypanosomiasis Eradication Campaign (PATTEC coordinated by the African Union. In order to achieve effective control of tsetse, there is need to produce elaborate plans to guide intervention programmes. A model intended to aid in the planning of intervention programmes and assist a fuller understanding of tsetse distribution was applied, in a pilot study in the Masoka area, Mid-Zambezi valley in Zimbabwe, and targeting two savannah species, Glossina morsitans morsitans and Glossina pallidipes.The field study was conducted between March and December 2015 in 105 sites following a standardized grid sampling frame. Presence data were used to study habitat suitability of both species based on climatic and environmental data derived from MODIS and SPOT 5 satellite images. Factors influencing distribution were studied using an Ecological Niche Factor Analysis (ENFA whilst habitat suitability was predicted using a Maximum Entropy (MaxEnt model at a spatial resolution of 250 m. Area Under the Curve (AUC, an indicator of model performance, was 0.89 for G. m. morsitans and 0.96 for G. pallidipes. We then used the predicted suitable areas to calculate the probability that flies were really absent from the grid cells where they were not captured during the study based on a probability model using a risk threshold of 0.05. Apart from grid cells where G. m. morsitans and G. pallidipes were captured, there was a high probability of presence in an additional 128 km2 and 144 km2 respectively.The modelling process promised to be useful in optimizing the outputs of presence/absence surveys, allowing the definition of tsetse infested areas with improved accuracy. The methodology proposed here can be extended to all the tsetse infested parts of Zimbabwe and may also be useful for other PATTEC national initiatives in other

    Full Text Available There is a recognized gap in the evidence base relating to the nature and components of interventions to address the psycho-social needs of HIV positive young people. We used mixed methods research to strengthen a community support group intervention for HIV positive young people based in Harare, Zimbabwe.A quantitative questionnaire was administered to HIV positive Africaid support group attendees. Afterwards, qualitative data were collected from young people aged 15-18 through tape-recorded in-depth interviews (n=10, 3 focus group discussions (FGDs and 16 life history narratives. Data were also collected from caregivers, health care workers, and community members through FGDs (n=6 groups and in-depth interviews (n=12. Quantitative data were processed and analysed using STATA 10. Qualitative data were analysed using thematic analysis.229/310 young people completed the quantitative questionnaire (74% participation. Median age was 14 (range 6-18 years; 59% were female. Self-reported adherence to antiretrovirals was sub-optimal. Psychological well being was poor (median score on Shona Symptom Questionnaire 9/14; 63% were at risk of depression. Qualitative findings suggested that challenges faced by positive children include verbal abuse, stigma, and discrimination. While data showed that support group attendance is helpful, young people stressed that life outside the confines of the group was more challenging. Caregivers felt ill-equipped to support the children in their care. These data, combined with a previously validated conceptual framework for family-centred interventions, were used to guide the development of the existing programme of adolescent support groups into a more comprehensive evidence-based psychosocial support programme encompassing caregiver and household members.This study allowed us to describe the lived experiences of HIV positive young people and their caregivers in Zimbabwe. The findings contributed to the enhancement of

  10. Postoperative Ileus in the Elderly

    2014-03-01

    Full Text Available Postoperative ileus is among the most common complications after surgery. Aging is associated with an increased colonic transit time, and anesthetic disturbance to colonic motility is often aggravated in the elderly. Postoperative ileus increases morbidity, prolongs the length of hospital stay, and constitutes a significant economic burden on the healthcare system. Multimodal enhanced recovery protocols, or fast-track surgeries, have been developed to improve postoperative recovery. Patient education, avoidance of perioperative fluid overload, selective use of nasogastric decompression, early ambulation, adopting a minimally invasive approach, early initiation of clear fluids, and gum chewing are all possible measures to reduce postoperative ileus. Thoracic epidural anesthesia is a well-established technique to hasten recovery, whereas insufficient data are available to ascertain the safety and efficacy of opioid-sparing analgesia in the elderly. The evidence is clear that traditional prokinetic medications are not helpful in the treatment or prevention of postoperative ileus. Early results suggest that alvimopan is a promising agent to reverse opioid-induced ileus. Since postoperative ileus is a multifactorial condition, a concerted effort is therefore necessary to prevent or decrease the duration of postoperative ileus using multimodal strategies.

    Correct interpretation of imaging findings in the postoperative shoulder is impaired by surgical distortion of normal anatomy and possible artifacts. Advanced postoperative imaging of the shoulder in addition to the selection of the best suited modality necessitates familiarity with the surgical procedure that has been performed and its consecutive morphological changes. This article reviews the most common arthroscopic and open techniques used for treatment of shoulder instability, lesions of the superior labral-bicipital complex, primery impingement, and rotator cuff tears, their typical postoperative imaging findings, as well as the diagnostic performance of cross sectional imaging techniques in the detection of recurrent lesions and complications.

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging. (orig.) [German] Die postoperative radiologische Bildgebung des Sprunggelenks kann auch fuer den erfahrenen Radiologen eine besondere Herausforderung darstellen. Die komplex aufgebaute Anatomie des Sprunggelenks, mit seinen multiplen Gelenkflaechen, Sehnen, Baendern und neurovaskulaeren Strukturen auf engstem Raum, kann durch Operationen signifikant veraendert und insbesondere in der Magnetresonanztomographie (MRT) verfaelscht dargestellt werden. Fuer eine fundierte Befundung und Beurteilung der Operationsergebnisse ist die Kenntnis der praeoperativen Diagnose, Zeitpunkt und Technik der durchgefuehrten Operation(en) sowie der aktuellen klinischen Symptomatik von grosser Bedeutung.

    Gastrointestinal disorders, diarrhoea in particular remain a major concern in South Africa and Zimbabwe resulting in high mortality rates when left untreated. This investigation was aimed at documenting herbal medicines used in the treatment of diarrhoea in South Africa and Zimbabwe. A review of literature on plant species used as remedies for diarrhoea in South Africa and Zimbabwe was undertaken by the use of different electronic databases such as Google Scholar, ScienceDirect, Scopus as well as library searches at the University of Fort Hare, South Africa and the National Herbarium of Zimbabwe (SRGH) in Harare, Zimbabwe. This study reported ten plant species most widely used to treat diarrhoea in South Africa and Zimbabwe. Of the lot, Sclerocarya birrea (A. Rich.) Hochst. was the most popular medicinal plant used as antidiarrhoeal remedy (11 literature citations) in South Africa and Zimbabwe, followed by Elephantorrhiza elephantina (Burch.) Skeels and Schotia brachypetala Sond. with eight literature citations each. The roots (47.4%) are the most frequently used plant parts, followed by bark (26.3%), leaves (21.1%) and rhizomes (5.3%). The documented antidiarrhoeal activities of this repository of selected plant species against diarrhoea causing agents such as rotavirus, Escherichia coli , Shigella , Campylobacter , Giardia , Entamoeba histolytica , Salmonella , Yersinia and Vibrio cholerae calls for further investigation aimed at isolating phytochemical compounds responsible for antidiarrhoeal activities, their mode of action, and also establish their safety and efficacy. This cross-cultural acceptance of antidiarrhoeal herbal medicines and the use of the same plant species in different geographical zones serve as an indication of the importance of herbal medicines in primary healthcare of local communities.

    Incidence of cholera outbreak is a serious issue in underdeveloped and developing countries. In Zimbabwe, after the massive outbreak in 2008–09, cholera cases and deaths are reported every year from some provinces. Substantial number of reported cholera cases in some provinces during and after the epidemic in 2008–09 indicates a plausible presence of seasonality in cholera incidence in those regions. We formulate a compartmental mathematical model with periodic slow-fast transmission rate to study such recurrent occurrences and fitted the model to cumulative cholera cases and deaths for different provinces of Zimbabwe from the beginning of cholera outbreak in 2008–09 to June 2011. Daily and weekly reported cholera incidence data were collected from Zimbabwe epidemiological bulletin, Zimbabwe Daily cholera updates and Office for the Coordination of Humanitarian Affairs Zimbabwe (OCHA, Zimbabwe). For each province, the basic reproduction number () in periodic environment is estimated. To the best of our knowledge, this is probably a pioneering attempt to estimate in periodic environment using real-life data set of cholera epidemic for Zimbabwe. Our estimates of agree with the previous estimate for some provinces but differ significantly for Bulawayo, Mashonaland West, Manicaland, Matabeleland South and Matabeleland North. Seasonal trend in cholera incidence is observed in Harare, Mashonaland West, Mashonaland East, Manicaland and Matabeleland South. Our result suggests that, slow transmission is a dominating factor for cholera transmission in most of these provinces. Our model projects cholera cases and cholera deaths during the end of the epidemic in 2008–09 to January 1, 2012. We also determine an optimal cost-effective control strategy among the four government undertaken interventions namely promoting hand-hygiene & clean water distribution, vaccination, treatment and sanitation for each province.

    2015-04-01

    Post-operative ileus (POI) is a common condition after surgery. Failure to restore adequate bowel function after surgery generates a series of complications and it is associated to patients frustration and discomfort, worsening their perioperative experience. Even mild POI can be source of anxiety and could be perceived as a drop out from the "straight-forward" pathway. Enhanced recovery programmes have emphasized the importance of early commencement of oral diet, avoiding the ancient dogmata of prolonged gastric decompression and fasting. These protocols with early oral feeding and mobilization have led to improved perioperative management and have decreased hospital length of stay, ameliorating patient's postoperative experience as well. Nonetheless, the incidence of POI is still high especially after major open abdominal surgery. In order to decrease the incidence of POI, minimally-invasive surgical approaches and minimization of surgical manipulation have been suggested. From a pharmacological perspective, a meta-analysis of pro-kinetics showed beneficial results with alvimopan, although its use has been limited by the augmented risk of myocardial infarction and the high costs. A more simple approach based on the postoperative use of chewing-gum has provided some benefits in restoring bowel function. From an anaesthesiological perspective, epidural anaesthesia/analgesia does not only reduce the postoperative consumption of systemic opioids but directly improve gastrointestinal function and should be considered where possible, at least for open surgical procedures. POI represents a common and debilitating complication that should be challenged with multi-disciplinary approach. Prospective research is warranted on this field and should focus also on patient s reported outcomes.

    In medical education, evaluating outcomes from programs intended to transform attitudes or influence career trajectories using conventional methods of monitoring is often difficult. To address this problem, the authors adapted the most significant change (MSC) technique to gain a more comprehensive understanding of the impact of the Medical Education Partnership Initiative (MEPI) program at the University of Zimbabwe College of Health Sciences. In 2014-2015, the authors applied the MSC to systematically examine the personal significance and level of positive transformation that individuals attributed to their MEPI participation. Interviews were conducted with 28 participants nominated by program leaders. The authors coded results inductively for prevalent themes in participants' stories and prepared profiles with representative quotes to place the stories in context. Stakeholders selected 9 themes and 18 stories to illustrate the most significant changes. Six themes (or outcomes) were expected, as they aligned with MEPI goals-becoming a better teacher, becoming a better clinician, increased interest in teaching, increased interest in research, new career pathways (including commitment to practice in Zimbabwe), and improved research skills. Three themes were unexpected-increased confidence, expanded interprofessional networks, and improved interpersonal interactions. The authors found the MSC to be a useful and systematic evaluation approach for large, complex, and transformative initiatives like MEPI. The MSC seemed to encourage participant reflection, support values inquiry by program leaders, and provide insights into the personal and cultural impacts of MEPI. Additional trial applications of the MSC technique in academic medicine are warranted.

    Sexuality in the teenager is often complicated by unplanned/unwanted pregnancy, abortion and the risks of STDs including AIDS. There is therefore a need for improved understanding of factors affecting adolescent sexuality and the implementation of programmes designed to improve their knowledge, risk awareness and subsequent behavioural outcomes. A multicentre study of reproductive health knowledge and behaviour followed by a health education intervention was undertaken amongst teenagers in selected countries of East, Central and Southern Africa. Reported here are findings at baseline derived from the Zimbabwe component on reproductive biology knowledge and behavior. A self-administered questionnaire was used among 1 689 adolescent pupils drawn from rural, urban, co-education, single sex, boarding and day secondary schools in Zimbabwe. Correct knowledge on reproductive biology as measured by the meaning and interpretation of menstruation and wet dreams varied by school from 68 pc to 86 pc, with a significant trend (p < 0,01) based on level of education at baseline. The reported mean age at which menarche took place was 13,5 years +/- 1,3 (mean +/- SD). First coitus was reported to have taken place at the mean age of 12 years for boys and 13,6 years for girls. Seventeen pc of the adolescent pupils reported that they were sexually experienced and 33,2 had relationships. There were misconceptions reported on menstruation with 23 pc reporting that it was an illness. Peers, followed by magazines were the first sources of information on various aspects of reproductive biology, both of which might not provide the correct first information. Among pupils reporting that they were sexually experienced, the largest proportion (56 pc) had unprotected sex. The findings point to the need for targeting the adolescent pupils for information on reproductive biology and increased awareness on the risks of pregnancy, STDs and HIV.

    Zimbabwe has started to scale up Option B+ for the prevention of mother-to-child transmission of HIV, but there is little published information about uptake or retention in care. This study determined the number and proportion of pregnant and lactating women in rural districts diagnosed with HIV infection and started on Option B+ along with six-month antiretroviral treatment (ART) outcomes. This was a retrospective record review of women presenting to antenatal care or maternal and child health services at 34 health facilities in Chikomba and Gutu rural districts, Zimbabwe, between January and March 2014. A total of 2728 women presented to care of whom 2598 were eligible for HIV testing: 76% presented to antenatal care, 20% during labour and delivery and 4% while breastfeeding. Of 2097 (81%) HIV-tested women, 7% were HIV positive. Lower HIV testing uptake was found with increasing parity, late presentation to antenatal care, health centre attendance and in women tested during labour. Ninety-one per cent of the HIV-positive women were started on Option B+. Six-month ART retention in care, including transfers, was 83%. Loss to follow-up was the main cause of attrition.

    Full Text Available The need to institute dispute resolution procedures in the Apostolic Faith Mission (AFM in Zimbabwe church informs this study. Remarkably, one of the most critical problems facing the AFM in Zimbabwe church is intrachurch disputes, which manifest in diverse forms such as pastors’ transfers disputes, election disputes and pastors’ performance disputes. Such disputes have produced undesirable consequences not only for pastors but also for the wellbeing of the church in general. Intrachurch disputes require internal mechanisms to manage them so that constructive rather than destructive results are achieved. To do this, internal dispute resolution procedures become critical as they provide a framework for the constructive resolution of disputes. The lived experience of disputes in the AFM in Zimbabwe church confirms the appropriateness of systems theory, which states that social institutions are vulnerable to disharmony owing to differing interacting elements. To mitigate the negative impact associated with disputes, this study proposes the need to institute dispute resolution procedures in the AFM in Zimbabwe, because the church currently relies only on disciplinary procedures to address disputes. The study further emphasises that instituting dispute resolution procedures will help the church handle disputes from within its ranks without necessarily involving local courts, which may have negative financial and relationship implications. Finally, the study develops a model for dispute resolution procedures as an instrument that can assist local churches in AFM in Zimbabwe church to handle disputes as and when they arise.

  1. Implementation of renewable technologies - Opportunities and barriers. Zimbabwe country study

    Renewable Energy Technologies (RETS) have over the years become an integral part of the energy supply chain in most developed countries. Recent projections show that 13.5% of the world's primary energy supply comes from renewable and this figure has an aggregated annual growth rate of 16%. Wind has the highest annual growth rate of 22% while the least annual growth rate of 2% is for hydropower. The main push for renewable like wind in the OECD countries are environmental concerns and the business aspect in power generation. The situation is however completely different in Africa, where the thrust for RETs is developmental based. Although the continent has abundant renewable energy resources like solar, biomass, wind and hydro potential, they have remained largely unexploited. Several efforts have been made to help African countries like Zimbabwe to exploit such resources. The main objectives of this country study included review of Zimbabwe's development of past RETs, establish barriers related lessons learnt from such projects and currently running RETs projects, identify barriers experienced by other projects and then select a few barrier removal projects and then develop them with the help of all stake holders in the country. The methodology of this study involved a review of past RETs projects to establish barriers faced and barriers related lessons learnt. An examination of the policy instruments related to RETs was done to establish how they promote the dissemination of the technologies as well as their adequacy. A survey of all possible RETs projects in the country was carried out and in this survey the end-users were visited and interviewed by the research team. An initial workshop, which was attended by all stake holders, was held in November 1999. An Advisory committee on RETs in Zimbabwe was then set up comprising of various stake holders from government, the private sector, research institutions, interviewed end-users and the NGO community

    Full Text Available Objective: Group B streptococci (GBS from Southern African areas have been less well characterized. Our objective was to study serotype and serovariant distribution of carrier GBS strains as part of a study of the epidemiology of GBS carriage in pregnant women from Zimbabwe. Materials and Methods: We studied GBS isolated from 121 healthy pregnant women living in Harare and surrounding areas, Zimbabwe. Capsular polysaccharide (CPS testing for serotype determination and surface-anchored protein testing for serosubtype determination were done by gene-based serotyping (PCR, except for the proteins R3 and a novel protein called Z, which were detected by antibody-based methods. Results: Strains of the CPS types Ia (15.7%, Ib (11.6%, II (8.3%, III (38.8%, V (24.0% and NT (1.7% were detected along with the strain-variable proteins Cί (15.7% of isolates, Cα (19.8%, Alp1 (epsilon-22.3%, Alp3 (5.0%, R4/Rib (46.3%, R3 (27.3%, Z (27.3%, and SAR5 (28.9%, which encodes the R5 protein. Up to four of the protein genes could be possessed or the gene product expressed by one and the same isolate. A total of 32 serovariants were detected. The findings assessed by us as most important were the very low prevalence of the gene Alp3 (Alp3 - 4.9%, high prevalence of R4 (Rib - 46.2%, the proteins R3 (27.3%, Z (27.3%, and of SAR5 (R5 - 28.9%. The low prevalence of Alp3, notably in GBS type V strains, differed from findings with CPS type V GBS from non-African areas. Bacteria of the various CPS types showed distinct CPS/protein-marker associations. Conclusion: The results are of importance in relation to regional variations of GBS phenotypes and genotypes and thus, of importance in planning and research in the context of future vaccine formulations.

O tempo cirúrgico (média ± desvio-padrão foi de 372,34 ± 107,84 minutos no grupo extubado imediatamente e 432,61 ± 117,30 minutos no grupo não-extubado. O risco relativo para a extubação imediata favorecer má evolução foi 0,81; enquanto para a extubação não imediata favorecer má evolução foi 1,5. CONCLUSÃO: É possível a extubação traqueal imediata com segurança de pacientes submetidos a cirurgias de ressecção pulmonar. Tal conduta facilita a recuperação pós-operatória fora da Unidade de Terapia Intensiva, resultando em benefícios aos pacientes e aos hospitais.OBJECTIVE: Early tracheal extubation following surgical procedures favors clinical evolution of patients and reduces incidence and time of stay in the Intensive Care Unit (ICU, minimizing hospital costs. Immediate postoperative period of pulmonary resections often takes place in the ICU and patients are kept intubated. This study evaluated hospital records of patients submitted to thoracotomy and a correlation between extubation time, postoperative evolution and ICU stay was established. METHODS: Retrospective cohort study of records of 121 patients submitted to pulmonary parenchyma resection (not biopsies was carried out. Stay in the ICU and time of tracheal extubation were related. Postoperative evolution was classified as good or bad according to occurrence of some of the following conditions: infections, respiratory disorders (reintubation, bronchospasm, acute pulmonary edema, need of tracheotomy, atelectasis, fistulae, re-operation due to bleeding and death. Among the two groups preoperative conditions, anesthetic physical status (American Society of Anesthesyologists - ASA criteria, presence of associated diseases, respiratory functional evaluation and duration of surgery were analyzed.

    Full Text Available Introduction: Postoperative pain remains as a problem. National studies report incidences of 31% for moderate and 22% for severe pain. Inadequate analgesia is related to dissatisfaction and adverse outcomes. The aim of this study was to describe the incidence and characteristics of the postoperative pain in the post-anesthesia care unit (PACU at Hospital Universitario San José of Popayán (HUSJ in patients undergoing general anesthesia during the first postoperative hour. Methods: Cohort study. We recruited patients attending PACU and undergoing procedures using general anesthesia, between 18 and 70 years. Using a standardized collection form medical history, demographic data, medical history, anesthetic management, intraoperative analgesia and postoperative pain assessment by verbal and numerical pain scale (1-10 were recorded. Postoperative outcome data were also collected in the PACU. Results: The incidence of severe postoperative pain at 10 minutes was 12.3% 95%CI [7.1-18.2] (19 patients. Within 30 minutes of assessment 4.5% 95%CI [1.3-8.4] (7 patients and 1.9% 60 minutes 95%CI [0-4.5] (3 patients. 48.7% required rescue analgesic at PACU. Incidence of postoperative nausea and vomiting (PONV was significantly different in patients requiring rescue analgesic. Conclusion: The incidence of severe postoperative pain in the first postoperative hour at HUSJ is close to 12% and it decreases as time goes by. Patients requiring rescue analgesic have a higher incidence of postoperative complications such as PONV.

  8. Tectonic setting of the Great Dyke, Chembadzi, Chewore and Atchiza layered complexes in Zimbabwe and Mozambique

    The Great Dyke of Zimbabwe is one of the largest ultramafic-mafic layered igneous complexexs in the world. Because of the economic importance of large layered intrusions like the Great Dyke, their tectonic setting is of great interest. The Chembadzi complex is a 14 km long, dyke-like layered intrusion up to 800m wide. The Chewore complex, which was thought to have the structure of an irregular lopolith, outcrops over an area of about 200 km in horst blocks in the lower Zambezi Valley in northern Zimbabwe. The Atchiza complex is situated just north of the Cahora Bassa lake and the Zambezi River valley in Mozambique. In considering the tectonic setting of the Great Dyke and its correlatives, most attention has been focussed on events in the Limpopo Mobile Belt, which were responsible for producing the fractures in the Zimbabwe craton that is occupied by the intrusives. 39 refs

    concealment of allocation processes and blinding of outcome assessors were poorly described. Due to inconsistent outcome reporting, data from 17 included trials could be pooled for some endpoints only. Eight trials compared tramadol administration with placebo and five trials found that the need for rescue analgesia in the postoperative care unit (PACU) was reduced in children receiving tramadol (RR 0.40; 95% CI 0.20 to 0.78; low quality evidence). Only one trial investigated the number of patients with moderate to severe pain, but a non-validated pain scale was used (very low quality evidence). Four trials compared morphine with tramadol administration. There was no clear evidence of difference in the need for rescue analgesia in the PACU (RR 1.25; 95% CI 0.83 to 1.89; low quality evidence) with tramadol compared with morphine. No trials could be pooled for the outcome 'number of patients with moderate to severe pain'. Three trials were included for the comparison of tramadol with nalbuphine. There was no clear evidence for the need for rescue analgesia in the PACU (RR 0,63; 95% CI 0.16 to 2.45; low quality evidence). Only one trial reported the number of patients with moderate to severe pain, but used a non-validated pain scale (very low quality evidence). Two out of six included trials, which compared pethidine with tramadol, reported the number of children with a need for rescue analgesia within the PACU and showed no clear evidence (RR 0.93; 95% CI 0.43 to 2.02; very low quality evidence). Two trials reported the number of patients with moderate to severe pain and showed a lower RR in patients treated with tramadol (RR 0.64; 95% CI 0.36 to 1.16; low quality evidence). Only one trial was included, which compared tramadol with fentanyl, reporting the number of patients with the need for rescue analgesia (very low quality evidence). Generally, adverse events were poorly reported. Most data could be pooled for the comparison with placebo focusing on the RR for postoperative

    Managing menses is a challenge for women in developing countries. Duet is a cervical barrier being developed for contraception and STI prevention. We explored the hypothetical acceptability of using Duet as a menstrual cup, among Zimbabwean women. A survey and focus group discussions (FGD) were conducted with 43 women aged 18-45 years to gain information about their menstrual practices and attitudes regarding the use of Duet for menstrual protection. All 43 women reported that if Duet were available, they would "definitely" try it, and that it was "very important" that Duet is low cost and easy to clean; 86% reported that using it would make a difference in their lives. FGD findings highlighted unhygienic practices due to the lack of affordable options for menstrual management and a genuine interest in Duet, including its potential use for multiple purposes (contraception, disease prevention and menstrual protection). Accessing affordable and hygienic menstrual protection was a problem for these Zimbabwean women. Duet appeared acceptable and it would be feasible to conduct a user-acceptability study of Duet as a menstrual cup in Zimbabwe.

  11. An Assessment of SMEs’ Financing by Commercial Banks in Zimbabwe

    2016-12-01

    Full Text Available Small-to-medium enterprises (SMEs play a key role in the world economy and contribute significantly to an economy’s output, income and employment. This paper seeks to assess the extent to which Zimbabwe’s commercial banks finance SMEs. Document analysis and an extensive review of the literature was undertaken to contextualize and draw a framework of analysis for the study. The literature shows that SMEs are of great socio-economic importance in developing countries but access to financial services for SMEs in Zimbabwe remains low. Zimbabwe’s economic challenges since 2000 to dollarization in 2009, the informalization of the SME sector, customers’ financial illiteracy and lack of training, lack of collateral security for loans, a high non-performing loans ratio, the lack of understanding of SMEs’ needs by banks, the inaccessibility of banks and the general lack of financial innovation are some of the major reasons for the low level of SME financing. A harmonised approach to policy suggestions for SMEs, lending institutions, the central bank and government to ensure the viability and growth of the SME sector are required and outlined. The research helps to formalize the SME sector considering its attendant benefits to the relevant players in the economy.

    A questionnaire survey, to estimate biofuel consumption rates in rural and urban households in Zimbabwe, was conducted during the months of March and April 1995. The survey formed part of an integrated campaign aimed at establishing the extent to which domestic biofuel burning in Africa contributes to the atmospheric trace gas budget. Five study areas, four rural and one urban, were covered by the survey. The forms of biofuel used in rural areas were found to be wood, agricultural residues and cow dung, with wood being predominant. When available, agricultural residues were the second most popular form of fuel. Cow dung was only used in situations of severe fuel shortages. On average, rural consumption rates of wood, agricultural residues and cow dung for this time of the year were found to be 3.2, 1.5 and 0.2 kg/capita/day respectively. Wood and agricultural residues were the only biofuels used by urban households and were consumed at rates of 1.6 and > 0.1 kg/capitaday respectively. Across the study areas, consumption rates were a function of fuel availability. (author)

  13. Education of the Peasantry in Zimbabwe as Internal Colonialism

    Directory of Open Access Journals (Sweden)

    Munyaradzi Hwami

    2014-05-01

    Full Text Available This article utilizes internal colonial analyses to explore and understand the difficult educational conditions students from peasantry background experience in Zimbabwe’s universities. The article proposes that the subordinate position and related educational experiences of peasantry students since the year 2000 are exploitative and to the advantage of the elite to such an extent that peasants are an internal colony. The analysis is informed by critical anti-colonial perspectives that observe the hegemonic tendencies of global and local capital in collusion with dictatorial elite nationalists. By use of a critical interpretive case study of purposefully sampled students and other relevant members of the university community from one public university, disturbing student experiences were excavated. Student narratives and experiences were analyzed using the constant comparative method and led to the conclusion that there is internal colonialism in Zimbabwe where an alliance of the state and the local and global corporate world are colluding to maintain their economic and political dominance. The article challenges those in education and academics that there is need for the decolonization of education by first identifying contemporary hegemonic forces and recognizing students from the peasantry as victims of the emerging kleptocratic capitalism.

    Aim: The aim of this paper was to contribute to an understanding of how female entrepreneurs in a patriarchal African society can work within cultural constraints to achieve success within their own terms of reference. Setting: The study took place in Zimbabwe among female entrepreneurs who had recently formalised their businesses Methods: Using a qualitative interpretive research design, in-depth, face-to-face interviews were conducted with 43 African female entrepreneurs running their own businesses in the Zimbabwean cities of Harare and Bulawayo. Results: The complex interplay of macro- (national cultural characteristics, meso- (institutional and social factors, and micro- (individual identity level factors shaped the ways in which the women dealt with the shackles of patriarchy, inequality and high power distance that had historically impeded their economic participation. Through their own agency, they mobilised their public and private identities separately, balancing the seemingly incompatible roles of home-maker vs entrepreneur. Conclusion: Zimbabwean women successfully managed the interaction between their different social roles and identities to balance domestic obligations with income generation to better the lives of their families.

  15. Coal prospects in Botswana, Mozambique, Zambia, Zimbabwe and Namibia

    Energy Technology Data Exchange (ETDEWEB)

    2013-12-01

    Increasing demand for coal in Asia is stimulating interest in the potentially large coal resources in Southern African countries such as Botswana, Mozambique, Zambia, Zimbabwe and Namibia. These countries have been slow to utilise their coal as local demand has been limited and the means to export coal has been inadequate. The governments in these regions are now recognising coal as a strategically important commodity, capable of earning foreign revenue but also adding value to the economy by generating much needed electricity. This report looks in turn at the role of coal in the energy economies of each of these countries. As in most emerging economies, the provision of a reliable and cost-effective supply of electricity to industries and people is essential for economic growth and the welfare of communities. Demand for Africa's mineral commodities such as diamonds and copper is driving a massive need for electricity and coal will play a major role. Not only does the mining industry need power, but with these growing industries come communities and commerce which are also in need of energy.

  16. Women and AIDS in Zimbabwe: the making of an epidemic.

    Science.gov (United States)

    Bassett, M T; Mhloyi, M

    1991-01-01

    As the AIDS epidemic in Africa assumes major proportions, the need to understand the social context in which heterosexual transmission occurs takes on urgent importance. In this article we explore how the intersection of traditional culture with the colonial legacy and present-day political economy has influenced family structure and sexual relations, and particularly the social position of women. Drawing on Zimbabwe's historical experience, we show how land expropriation, rural impoverishment, and the forcible introduction of male migrant labor fostered new patterns of sexual relations, characterized by multiple partners. Traditional patriarchal values reinterpreted in European law resulted in further subjugation of women as even limited rights to ownership were withdrawn. For many women, sexual relations with men, either within marriage (for the majority) or outside, become inextricably linked to economic and social survival. In this setting, all sexually transmitted diseases became rampant, including genital ulcer, which facilitates transmission of the human immunodeficiency virus (HIV). Intervention programs to halt the spread of AIDS need to take into the account the epidemic's historical roots and social nature. For example, efforts to reduce risk of HIV transmission should seek to expand women's limited options, both technically (e.g., by providing alternatives to condoms) and socially (e.g., by promoting employment).

    BACKGROUND: Postoperative ileus has traditionally been accepted as a normal response to tissue injury. No data support any beneficial effect of ileus and indeed it may contribute to delayed recovery and prolonged hospital stay. Efforts should, therefore, be made to reduce such ileus. METHODS......: Material was identified from a Medline search of the literature, previous review articles and references cited in original papers. This paper updates knowledge on the pathophysiology and treatment of postoperative ileus. RESULTS AND CONCLUSION: Pathogenesis mainly involves inhibitory neural reflexes...... only cisapride is proven beneficial; the effect of early enteral feeding remains unclear. However, postoperative ileus may be greatly reduced when all of the above are combined in a multimodal rehabilitation strategy....

  20. Single night postoperative prone posturing in idiopathic macular hole surgery.

    LENUS (Irish Health Repository)

    2012-02-01

    Purpose. To evaluate the role of postoperative prone posturing for a single night in the outcome of trans pars plana vitrectomy (TPPV) with internal limiting membrane (ILM) peel and 20% perfluoroethane (C2F6) internal tamponade for idiopathic macular hole. Methods. This prospective trial enrolled 14 eyes in 14 consecutive patients with idiopathic macular hole. All eyes underwent TPPV with vision blue assisted ILM peeling with and without phacoemulsification and intraocular lens (IOL) for macular hole. Intraocular gas tamponade (20% C2F6) was used in all cases with postoperative face-down posturing overnight and without specific posturing afterwards. LogMAR visual acuity, appearance by slit-lamp biomicroscopy, and ocular coherence tomography (OCT) scans were compared preoperatively and postoperatively to assess outcome. Results. Among 14 eyes recruited, all eyes were phakic; 50% of patients underwent concurrent phacoemulsification with IOL. The macular holes were categorized preoperatively by OCT appearance, 4 (28.57%) were stage 2, 7 (50%) were stage 3, and 3 (21.43%) were stage 4. Mean macular hole size was 0.35 disk diameters. Symptoms of macular hole had been present for an average of 6.5 months. All holes (100%) were closed 3 and 6 months postoperatively. Mean visual acuity (logMAR) was improved to 0.61 at 3 months and was stable at 6 months after the surgery. None of the eyes had worse vision postoperatively. Conclusions. Vitrectomy with ILM peeling and 20% C2F6 gas with a brief postoperative 1 night prone posturing regimen is a reasonable approach to achieve anatomic closure in idiopathic macular hole. Concurrent cataract extraction did not alter outcomes and was not associated with any additional complications.

    2005-06-01

    Full Text Available Sera from 173 apparently healthy, unvaccinated dogs from 4 widely separated communal lands in Zimbabwe were tested by ELISA for antibodies against canine distemper virus. Overall, 82 % were positive with high prevalences found in each communal land. The highest seroprevalence was in dogs between 1 and 2 years of age (91 %; 49/54. These results show dogs in the communal lands of Zimbabwe are commonly exposed to canine distemper virus and that a substantial number survive infection. The role that the virus might play in the high mortality rate of the dog population on communal land warrants further investigation.

    Full Text Available Introduction. Chronic pancreatitis (CP is considered an inflammatory disease that may cause varying degrees of pancreatic dysfunction. Conservative and surgical treatment options are available depending on dysfunction severity. Presentation of Case. A 36-year-old male with history of heavy alcohol consumption and diagnosed CP underwent a duodenal-preserving pancreatic head resection (DPPHR or Beger procedure after conservative treatment failure. Refractory pain was reported on follow-up three months after surgery and postoperative imaging uncovered stones within the main pancreatic duct and intestinal dilation. The patient was subsequently subjected to another surgical procedure and intraoperative findings included protein plugs within the main pancreatic duct and pancreaticojejunal anastomosis stricture. A V-shaped enlargement and main pancreatic duct dilation in addition to the reconstruction of the previous pancreaticojejunal anastomosis were performed. The patient recovered with no further postoperative complications in the follow-up at an outpatient clinic. Discussion. Main duct and pancreaticojejunal strictures are an unusual complication of the Beger procedure but were identified intraoperatively as the cause of patient’s refractory pain and explained intraductal protein plugs accumulation. Conclusion. Patients that undergo Beger procedures should receive close outpatient clinical follow-up in order to guarantee postoperative conservative treatment success and therefore guarantee an early detection of postoperative complications.

    Full Text Available While technology has been embraced by most of the people, use of smart phones in the classroom has been received with mixed feelings. Some say it enhances learning while others complain that it disturbs instruction. This research wanted to find out the stance of secondary school teachers on this issue in Zimbabwe. A sample of 50 randomly selected teachers from 10 randomly selected secondary schools in Gweru District, Midlands Province in Zimbabwe was used. Data from self-constructed questionnaires were analyzed by SPSS mainly on descriptive statistics and correlation. Findings showed that teachers possess smart phones which they use for researching and other instructional purposes with moderate expertise. Teachers consider smart phones as hand-held computers that can enhance learning for they have high engagement potential and they extend classroom walls allowing students to engage with the global village. A correlation computation showed that there is a significant relationship between perceived problems of smart phones and smart phones integration factors. However, respondents felt that smart phones can cause lower levels of attention during lessons and allows cheating and copying during exams. They also concurred that teachers’ technical skills lag behind those of digital native students. Thus, they foresaw instructional problems on the part of the teachers on the use of smart phones in the classroom and were against their use. They doubted if the use of smart phones can improve the pass rate and whether they wanted their students to bring cell phones and use them during lessons for they perceived problems in controlling students using them. They also doubted if schools in Zimbabwe would ever benefit if students are allowed to use their phones in class. The study concluded that teachers in Zimbabwe are not yet prepared to have students use smart phone in the classroom and recommended for further research on the potential benefits of using

    Postoperative chylothorax is a relatively rare but potentially fatal complication caused by iatrogenic injury to thoracic duct system, with an incidence ranging from 2 to 4% after major lung surgery or esophagectomy. The pathophysiologic features of chylothorax include dehydration, loss of nutrients and immunological components. Intraopreative prevention is the first step for the management, and treatment options include conservative therapy, percutaneous intervention, and redo-operation. Although the treatment algorithm has not been standardized, chylothorax which is refractory to conservative treatment, or that with high output greater than 1,000 ml/day should be treated aggressively with thoracic duct embolization or redo-operation in a timely fashion. We herein review the anatomy and physiology of thoracic duct system and describe the overview of prevention and each theapeutic options of postoperative chylothorax.

    Postoperative management of patients suffering from symptoms of the temporomandibular joint does not differ considerably from the one of preoperative examination protocols. Knowledge of previous surgery helps to plan patient work-up and to interpret normal postoperative findings (eminectomy, discectomy, susceptibility artefacts from metallic residues..) and typical complications (intraarticular loose bodies, dislocations, avascular necrosis, foreign body granulomatous reactions) appropriately. (orig.) [German] Wie auch in anderen Koerperregionen differiert das Diagnoseprotokoll von prae- und postoperativen Patienten mit Beschwerden des Kiefergelenks nicht wesentlich voneinander. Die Kenntnis des vorangegangenen Eingriffs hilft allerdings, die Untersuchung entsprechend zu planen und den Befund im Kontext richtig zu bewerten, um moegliche Komplikationen (intraartikulaere Fragmente, Dislokationen, avaskulaere Nekrose, Fremdkoerperreaktionen) und zu erwartende Befunde (Eminektomie, Diskektomie, Metallartefakte usw.) richtig zu interpretieren.

    Full Text Available The management and allocation of water from multi-reservoir systems is complex and thus requires dynamic modelling systems to achieve optimality. A multi-reservoir system in the Southern Lowveld of Zimbabwe is used for irrigation of sugarcane estates that produce sugar for both local and export consumption. The system is burdened with water allocation problems, made worse by decommissioning of dams. Thus the aim of this research was to develop an operating policy model for the Lowveld multi-reservoir system.The Mann Kendall Trend and Wilcoxon Signed-Rank tests were used to assess the variability of historic monthly rainfall and dam inflows for the period 1899–2015. The WEAP model was set up to evaluate the water allocation system of the catchment and come-up with a reference scenario for the 2015/2016 hydrologic year. Stochastic Dynamic Programming approach was used for optimisation of the multi-reservoirs releases.Results showed no significant trend in the rainfall but a significantly decreasing trend in inflows (p < 0.05. The water allocation model (WEAP showed significant deficits ( ∼  40 % in irrigation water allocation in the reference scenario. The optimal rule curves for all the twelve months for each reservoir were obtained and considered to be a proper guideline for solving multi- reservoir management problems within the catchment. The rule curves are effective tools in guiding decision makers in the release of water without emptying the reservoirs but at the same time satisfying the demands based on the inflow, initial storage and end of month storage.

    This paper discusses indigenous environmental indicators for the occurrence of malaria in ward 11, 15 and 18 of Gwanda district, Zimbabwe. The study was inspired by the successes of use of indigenous knowledge systems in community based early warning systems for natural disasters. To our knowledge, no study has examined the relationship between malaria epidemics and climatic factors in Gwanda district. The aim of the study was to determine the environmental indicators for the occurrence of malaria. Twenty eight key informants from the 3 wards were studied. Questionnaires, focus group discussions and PRA sessions were used to collect data. Content analysis was used to analyse the data. The local name for malaria was 'uqhuqho' literally meaning a fever. The disease is also called, "umkhuhlane wemiyane" and is derived from the association between malaria and mosquitoes. The findings of our study reveal that trends in malaria incidence are perceived to positively correlate with variations in both temperature and rainfall, although factors other than climate seem to play an important role too. Plant phenology and insects are the commonly used indicators in malaria prediction in the study villages. Other indicators for malaria prediction included the perceived noise emanating from mountains, referred to as "roaring of mountains" and certain behaviours exhibited by ostriches. The results of the present study highlight the importance of using climatic information in the analysis of malaria surveillance data, and this knowledge can be integrated into the conventional health system to develop a community based malaria forecasting system.

    Review of a prospective database registry of surgical patients with adolescent idiopathic scoliosis (AIS). The purpose of this study was to examine the prevalence of postoperative pain and its impact on patient-reported postoperative outcomes using the Scoliosis Research Society (SRS)-22 outcomes questionnaire. Although reportedly rare, postoperative pain can be a devastating situation for the patient with AIS. Most recent studies examining outcomes in AIS surgical treatment use the SRS Pain domain score to assess pain in this population. A prospectively enrolled multicenter database was queried. Patients with minimum 2-year follow-up and 2-year SRS scores were included. Postoperative pain after the acute phase of recovery when reported by the patient to the treating surgeon/clinical team in follow-up is recorded as a complication in the database. Patients included in this series were gr
