The objective of this study was to determine the clinical and laboratory characteristics, psychiatric manifestations and magnetic resonance imaging (MRI) findings in children and adolescents with Sydenham chorea (SyC). The imaging examination was repeated 1 year after the acute phase of SyC. There were 19 patients with a mean age of 11.7 years and a predominance of females (79%);68% had generalized chorea and 53% moderate chorea. SyC presented as an isolated manifestation in 74%. No association between SyC and obsessive-compulsive disorder was found. Mental health problems were present in 45% of the patients. MRI analysis revealed persistent alterations in the caudate nucleus in three patients (16%), who presented recurrent episodes of chorea during the study. In one patient, MRI revealed the presence of nodular heteropathy close to the caudate nucleus region. We conclude that attention problems can be associated with acute clinical features of SyC and persistent alterations in the basal nuclei, evidenced by MRI, can be found in some patients who tend to suffer prolonged attacks and a greater number of recurrences.

Full Text Available Background: Migraine is a common disorder which has psychiatric sequelae. Objective: The objective of this study was to determine the clinical pattern and psychiatric comorbidity of migraine. Materials and Methods: 100 cases of migraine seen over a period of one year were analysed to know the sociodemographic characteristics, clinical pattern and psychiatric morbidity. Results: Maximum patients were between 31-40 years of age group (40%, females (78.0%, married (76% and housewives (56.0%. Family history of migraine was present in 12% cases. Average age of onset was 22 years. Unilateral and throbbing type of headache was most common. The commonest frequency was one to two per week. Migraine without aura was commonest sub-type (80%. Generalized anxiety disorder (F41.1 was the most common psychiatric disorder (34%, followed by mixed anxiety and depressive disorder (F41.2 (18% and depressive episode (F32 (14%. In 22% cases, no psychiatric disorder could be elicited. Conclusion: The present study confirms that majority patients with migraine had psychiatric disorders. This needs timely detection and appropriate intervention to treat and control the migraine effectively.

The manner in which medical care is reimbursed in the United States has resulted in significant consolidation in the U.S. health care system. One of the consequences of this has been the development of centralized clinical microbiology laboratories that provide services to patients receiving care in multiple off-site, often remote, locations. Microbiology specimens are unique among clinical specimens in that optimal analysis may require the maintenance of viable organisms. Centralized laboratories may be located hours from patient care settings, and transport conditions need to be such that organism viability can be maintained under a variety of transport conditions. Further, since the provision of rapid results has been shown to enhance patient care, effective and timely means for generating and then reporting the results of clinical microbiology analyses must be in place. In addition, today, increasing numbers of patients are found to have infection caused by pathogens that were either very uncommon in the past or even completely unrecognized. As a result, infectious disease specialists, in particular, are more dependent than ever on access to high-quality diagnostic information from clinical microbiology laboratories. In this point-counterpoint discussion, Robert Sautter, who directs a Charlotte, NC, clinical microbiology laboratory that provides services for a 40-hospital system spread over 3 states in the southeastern United States explains how an integrated clinical microbiology laboratory service has been established in a multihospital system. Richard (Tom) Thomson of the NorthShore University HealthSystem in Evanston, IL, discusses some of the problems and pitfalls associated with large-scale laboratory consolidation.

The aim of this article is to assess the level of development of clinical ethics consultation in psychiatric institutions in North Rhine-Westphalia. Survey among medical directors, directors of nursing and administrative directors of all psychiatric acute clinics and forensic psychiatric hospitals in North Rhine-Westphalia. 113 persons working in psychiatric acute clinics responded (reponse rate: 48 %) and 13 persons working in forensic psychiatric hospitals (response rate 54 %). We received at least one response from 89 % of all psychiatric acute clinics and from 100 % of all forensic psychiatric hospitals. 90 % of the responding psychiatric acute clinics and 29 % of the responding forensic psychiatric hospitals have already implemented clinical ethics consultation. Clinical ethics consultation is more widespread in psychiatric institutions than was hitherto assumed. Future medical ethics research should therefore give greater attention to the methodology and the quality of clinical ethics consultation in psychiatric practice. © Georg Thieme Verlag KG Stuttgart · New York.

Out-of-state flat-rate mail order contract laboratories operating from states which have little or no legal control over them can do business in California without obedience to regulations that govern laboratories located within the state. The flat-rate contract principle under which some out-of-state laboratories operate is illegal in California. The use of such laboratories increases physician liability. Legislation for the control of these laboratories is difficult to construct, and laws which might result would be awkward to administer. The best remedy is for California physicians not to use an out-of-state laboratory offering contracts or conditions that it could not legally offer if it were located in California. PMID:14165875

Psychiatric disorders are linked to a variety of biological, psychological, and contextual causes and consequences. Laboratory studies have elucidated the importance of several key physiological and behavioral biomarkers in the study of psychiatric disorders, but much less is known about the role of these biomarkers in naturalistic settings. These gaps are largely driven by methodological barriers to assessing biomarker data rapidly, reliably, and frequently outside the clinic or laboratory. Mobile health (mHealth) tools offer new opportunities to study relevant biomarkers in concert with other types of data (e.g., self-reports, global positioning system data). This review provides an overview on the state of this emerging field and describes examples from the literature where mHealth tools have been used to measure a wide array of biomarkers in the context of psychiatric functioning (e.g., psychological stress, anxiety, autism, substance use). We also outline advantages and special considerations for incorporating mHealth tools for remote biomarker measurement into studies of psychiatric illness and treatment and identify several specific opportunities for expanding this promising methodology. Integrating mHealth tools into this area may dramatically improve psychiatric science and facilitate highly personalized clinical care of psychiatric disorders. Copyright © 2016 Elsevier Ltd.

This study reports on research undertaken to identify the skills and competencies of forensic psychiatric nurses working in secure psychiatric services in the UK. The rationale for this research is the lack of clarity in the role definition of nurses working in these environments and the specific content that may underscore the curriculum for training forensic nurses. Over 3300 questionnaires were distributed to forensic psychiatric nurses, non-forensic psychiatric nurses and other disciplines and information obtained on (1) the perceived clinical problems that give forensic nurses the most difficulty; (2) the skills best suited to overcome those problems; and (3) the priority aspects of clinical nursing care that needs to be developed. A 35% response rate was obtained with 1019 forensic psychiatric nurses, 110 non-forensic psychiatric nurses and 43 other disciplines. The results highlighted a 'top ten' list of main problems with possible solutions and main areas for development. The conclusions drawn include a focus on skills and competencies regarding the management of personality disorders and the management of violence and aggression.

Test results from clinical laboratories must ensure accuracy, as these are crucial in several areas of health care. It is necessary that the laboratory implements quality assurance to achieve this goal. The implementation of quality should be audited by independent bodies,referred to as accreditation bodies. Accreditation is a third-party attestation by an authoritative body, which certifies that the applicant laboratory meets quality requirements of accreditation body and has demonstrated its competence to carry out specific tasks. Although in most of the countries,accreditation is mandatory, in India it is voluntary. The quality requirements are described in standards developed by many accreditation organizations. The internationally acceptable standard for clinical laboratories is ISO15189, which is based on ISO/IEC standard 17025. The accreditation body in India is the National Accreditation Board for Testing and Calibration Laboratories, which has signed Mutual Recognition Agreement with the regional cooperation the Asia Pacific Laboratory Accreditation Cooperation and with the apex cooperation the International Laboratory Accreditation Cooperation.

Violence risk prediction is a priority issue for clinicians working with mentally disordered offenders. The aim of the present study was to determine violence risk factors in acute psychiatric inpatients. The study was conducted in a locked, short-term psychiatric inpatient unit and involved 374 patients consecutively admitted in a 1-year period. Sociodemographic and clinical data were obtained through a review of the medical records and patient interviews. Psychiatric symptoms at admission were assessed using the Brief Psychiatric Rating Scale (BPRS). Psychiatric diagnosis was formulated using the Structured Clinical Interview for DSM-IV. Past aggressive behavior was evaluated by interviewing patients, caregivers or other collateral informants. Aggressive behaviors in the ward were assessed using the Overt Aggression Scale. Patients who perpetrated verbal and against-object aggression or physical aggression in the month before admission were compared to non-aggressive patients, moreover, aggressive behavior during hospitalization and persistence of physical violence after admission were evaluated. Violent behavior in the month before admission was associated with male sex, substance abuse and positive symptoms. The most significant risk factor for physical violence was a past history of physically aggressive behavior. The persistent physical assaultiveness before and during hospitalization was related to higher BPRS total scores and to more severe thought disturbances. Higher levels of hostility-suspiciousness BPRS scores predicted a change for the worse in violent behavior, from verbal to physical. A comprehensive evaluation of the history of past aggressive behavior and psychopathological variables has important implications for the prediction of violence in psychiatric settings.
Full Text Available Abstract Background Patients admitted to a psychiatric hospital with suicidal behavior (SB are considered to be especially at high risk of suicide. However, the number of studies that have addressed this patient population remains insufficient compared to that of studies on suicidal patients in emergency or medical settings. The purpose of this study is to seek features of a sample of newly admitted suicidal psychiatric patients in a metropolitan area of Japan. Method 155 suicidal patients consecutively admitted to a large psychiatric center during a 20-month period, admission styles of whom were mostly involuntary, were assessed using Structured Clinical Interviews for DSM-IV Axis I and II Disorders (SCID-I CV and SCID-II and SB-related psychiatric measures. Associations of the psychiatric diagnoses and SB-related characteristics with gender and age were examined. Results The common DSM-IV axis I diagnoses were affective disorders 62%, anxiety disorders 56% and substance-related disorders 38%. 56% of the subjects were diagnosed as having borderline PD, and 87% of them, at least one type of personality disorder (PD. SB methods used prior to admission were self-cutting 41%, overdosing 32%, self-strangulation 15%, jumping from a height 12% and attempting traffic death 10%, the first two of which were frequent among young females. The median (range of the total number of SBs in the lifetime history was 7 (1-141. Severity of depressive symptomatology, suicidal intent and other symptoms, proportions of the subjects who reported SB-preceding life events and life problems, and childhood and adolescent abuse were comparable to those of the previous studies conducted in medical or emergency service settings. Gender and age-relevant life-problems and life events were identified. Conclusions Features of the studied sample were the high prevalence of affective disorders, anxiety disorders and borderline PD, a variety of SB methods used prior to admission

The capacity to work productively is a key component of health and emotional well-being. People who work in health care can be exposed to the fatigue of care. Compassion fatigue has been described as an occupational hazard specific to clinical work related severe emotional distress. In our study, we have evaluated compassion fatigue in a mental health group (47 psychiatric staff) and its relationship with inpatients (237 inpatients) affected by some psychiatric disorders. At baseline, the more significant data indicate a high percentage of Job Burnout and Compassion Fatigue in psychiatric nurses (respectively, 39.28%, 28.57%). Significant Compassion Fatigue percentage is present also in psychologist group (36.36%). Finally, in psychiatrists, the exposure to patients increased vicarious trauma (28.57%), but not job burnout. After a year of participation in Balint Groups, the psychiatric staff presented an overall reduction in total mean score in any administered scale (CBI: pfatigue causes concern among mental health professionals, and Balint Groups may represent a therapeutic strategy to help health professionals to face difficulties in challenging work environments.

The objective of this study was to clarify whether the communication skills (CS) of clinical residents change before and after psychiatric training and, if so, what factors are related to the change. The 44 clinical residents who agreed to participate in this study were provided with an originally developed self-accomplished questionnaire survey on CS (communication skills questionnaire [CSQ]) and a generally used questionnaire on self-esteem, anxiety, and depressive mood considered to be related to CS at the start and end of a 2-month psychiatric training session. Statistical analysis was conducted for the 34 residents who completed both questionnaires. The CSQ score (t: -2.17, P self-esteem and negatively with anxiety and depressive tendency. The amount of change in assertive CS score showed a weakly positive correlation with self-esteem. The results suggested that CS, including assertive CS and cooperative CS, were improved by the psychiatric training. Increasing self-esteem and reducing the tendency toward depression and anxiety are considered to be useful for further improving CS. © 2011 The Authors.

A consultation model between primary care physicians and psychiatrists that has been in operation for 12 years in the Jerusalem district of the Clalit Health Services in Israel is evaluated. In this model psychiatrists provide consultations twice a month at the primary care clinic. All patients are referred by their family physicians. Communication between the psychiatric consultant and the referring physician is carried out by telephone, correspondence and staff meetings. Evaluation of the psychiatric care consultation model in which a psychiatrist consults at the primary care clinic. A questionnaire-based survey distributed to 17 primary care physicians in primary care clinics in Jerusalem in which a psychiatric consultant is present. Almost all of the doctors (93%) responded that the consultation model was superior to the existing model of referral to a secondary psychiatric clinic alone and reduced the workload in caring for the referred patients. The quality of psychiatric care was correlated with the depression prevalence among patients referred for consultation at their clinic (r=0.530, p=0.035). In addition, correlation was demonstrated between primary care physicians impression of alleviation of care of patients and their impression of extent of the patients' cooperation with the consulting psychiatrist (r=0.679, p = 0.015) Conclusions: Very limited conclusions may be drawn from this questionnaire distributed to primary care physicians who were asked to assess psychiatric consultation in their clinic. Our conclusion could be influenced by the design and the actual distribution of the questionnaires by the consulting psychiatrist. Nevertheless answers to the questionnaire might imply that the consultation model of care between a psychiatric consultant and the primary care physician, where the patient's primary care physician takes a leading role in his psychiatric care, is perceived by family physicians as a good alternative to referral to a psychiatric

Delusional infestation, which encompasses both delusions of parasitosis and delusions of infestation with inanimate objects (sometimes called Morgellons disease), has been said to represent a distinct and encapsulated delusion, that is, a stand-alone diagnosis. Anecdotally, we have observed that patients with delusional infestation often have one or more psychiatric comorbid conditions and that delusional infestation should not be regarded as a stand-alone diagnosis. The purpose of this study was to identify whether patients with delusional infestation have psychiatric comorbid conditions. We therefore identified patients who had been formally evaluated in the Department of Psychiatry during their visit to Mayo Clinic. We retrospectively searched for and reviewed the cases of all patients with delusional infestation seen from 2001 through 2007 at Mayo Clinic, Rochester, Minnesota, and who underwent psychiatric evaluation. The diagnoses resulting from psychiatric evaluation were analyzed. During the 7-year study period, 109 patients seen for delusional infestation at Mayo Clinic were referred to the Department of Psychiatry, 54 (50%) of whom actually followed through with psychiatric consultation. Of these 54 patients, 40 (74%) received additional active psychiatric diagnoses; 14 patients (26%) had delusional infestation alone. Abnormal personality traits were rarely documented. Most patients with delusional infestation have multiple coexisting or underlying psychiatric disorders. Therefore, evaluation by a psychiatrist, when possible, is advised for all patients with delusional infestation. Copyright © 2012 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

American hospitals are increasingly turning to service outsourcing to reduce costs, including laboratory services. Studies of this practice have largely focused on nonacademic medical centers. In contrast, academic medical centers have unique practice environments and unique mission considerations. We sought to elucidate and analyze clinical laboratory outsourcing experiences in US academic medical centers. Seventeen chairs of pathology with relevant experience were willing to participate in in-depth interviews about their experiences. Anticipated financial benefits from joint venture arrangements often eroded after the initial years of the agreement, due to increased test pricing, management fees, duplication of services in support of inpatients, and lack of incentive for utilization control on the part of the for-profit partner. Outsourcing can preclude development of lucrative outreach programs; such programs were successfully launched in several cases after joint ventures were either avoided or terminated. Common complaints included poor test turnaround time and problems with test quality (especially in molecular pathology, microbiology, and flow cytometry), leading to clinician dissatisfaction. Joint ventures adversely affected retention of academically oriented clinical pathology faculty, with adverse effects on research and education, which further exacerbated clinician dissatisfaction due to lack of available consultative expertise. Resident education in pathology and in other disciplines (especially infectious disease) suffered both from lack of on-site laboratory capabilities and from lack of teaching faculty. Most joint ventures were initiated with little or no input from pathology leadership, and input from pathology leadership was seen to have been critical in those cases where such arrangements were declined or terminated.

To characterize nationwide variation and factors associated with clinical laboratories': (1) capabilities to send structured test results electronically to ordering practitioners' EHR systems; and (2) their levels of exchange activity, as measured by whether they sent more than three-quarters of their test results as structured data to ordering practitioners' EHR systems. A national survey of all independent and hospital laboratories was conducted in 2013. Using an analytic weighted sample of 9382 clinical laboratories, a series of logistic regression analyses were conducted to identify organizational and area characteristics associated with clinical laboratories' exchange capability and activity. Hospital-based clinical laboratories (71%) and larger clinical laboratories (80%) had significantly higher levels of capability compared to independent (58%) and smaller laboratories (48%), respectively; though all had similar levels of exchange activity, with 30% of clinical laboratories sending 75% or more of their test results electronically. In multivariate analyses, hospital and the largest laboratories had 1.87 and 4.40 higher odds, respectively, of possessing the capability to send results electronically compared to independent laboratories (pLaboratories located in areas with a higher share of potential exchange partners had a small but significantly greater capability to send results electronically and higher levels of exchange activity(pClinical laboratories' capability to exchange varied by size and type; however, all clinical laboratories had relatively low levels of exchange activity. The role of exchange partners potentially played a small but significant role in driving exchange capability and activity. Published by Elsevier B.V.

Pain is one of the most ubiquitous problems of today's world, its impact being far-reaching. Current conceptualizations of pain medicine adopt a bio-psycho-social perspective. In this model, pain is best described as an interactive, psycho-physiological behavioral pattern that cannot be divided into independent psycho-social and physical components. Neurophysiologic substrates of the pain experience can be broken down into the pain transmission elements emanating from peripheral, spinal, and supra-spinal processes. There are many complex mechanisms involved in pain processing within the central nervous system, being influenced by genetics, interaction of neurotransmitters and their receptors, and pain- augmenting and pain-inhibiting neural circuits. The patient's emotional experiences, beliefs and expectations may determine the outcome of treatment, and are fully emphasized in the focus of treatment interventions. There are several common psychiatric disorders accompanying and complicating the experience of pain that warrant clinical attention and that can be the focus of psychiatric treatment. These include depression, anxiety, sleep disorders, somatoform disorders, substance-related disorders and personality disorders. Complex and disabling pain conditions often require comprehensive pain treatment programs, involving interdisciplinary and multimodal treatment approaches. There are many roles that the psychiatrist can perform in the assessment and treatment of the patients with pain, individually tailored to meet the specific needs of the patient. Rational poly-pharmacy is of a high importance in the treatment of patients with chronic pain, with antidepressants and anticonvulsants contributing as the important adjuvant analgesic agents.

This case study investigation considers typical and potentially unique characteristics of older (> 50 years) Borderline Personality Disorder (BPD) patients and describes their impact on an inpatient psychiatric unit encompassing a therapeutic milieu setting and multidisciplinary treatment teams. The somatization of symptoms, in particular, and the associated therapeutic, medical, and psychopharmacological interventions, result in prolonged and elaborate treatments that undermine clinical and personal boundaries, clash with managed care directives, and engender frustrating and elusive transferential and countertransferential reactions. Moreover, the guilt-inducing nature of somatization and physical frailty in older individuals, combined with the well-documented ability of BPD patients, regardless of age, to incite stormy and 'split' relationships, are linked characteristics that may describe a diagnostic subtype of BPD. Rather than suggesting a diminution of psychopathology as BPD patients age, the results of this investigation indicate that their persistent difficulties may only be altering in content and in pathological adaptation to changing needs.

To determine the effects of multidisciplinary, nurse-led psychiatric consultation on behavioral problems of nursing home residents. Residents often suffer from psychiatric symptoms, while staff psychiatric expertise varies. A pre-post study was conducted in seven homes using the Neuropsychiatric Inventory Nursing Home version (NPI-NH). In 71 consultations during 18 months, 56-75% of residents suffered from agitation/aggression, depression, anxiety, and disinhibition. Post-intervention (n = 54), frequency, and severity of psychiatric symptoms were significantly and clinically meaningfully reduced. Also, staff suffered from less work stress. Nurse-led psychiatric consultation is valuable to both nursing home residents and staff. © 2015 Wiley Periodicals, Inc.

Imagine a clinical microbiology laboratory where a patient's specimens are placed on a conveyor belt and sent on an automation line for processing and plating. Technologists need only log onto a computer to visualize the images of a culture and send to a mass spectrometer for identification. Once a pathogen is identified, the system knows to send the colony for susceptibility testing. This is the future of the clinical microbiology laboratory. This article outlines the operational and staffing challenges facing clinical microbiology laboratories and the evolution of automation that is shaping the way laboratory medicine will be practiced in the future.

Laboratory testing is a highly complex process and, although laboratory services are relatively safe, they are not as safe as they could or should be. Clinical laboratories have long focused their attention on quality control methods and quality assessment programs dealing with analytical aspects of testing. However, a growing body of evidence accumulated in recent decades demonstrates that quality in clinical laboratories cannot be assured by merely focusing on purely analytical aspects. The more recent surveys on errors in laboratory medicine conclude that in the delivery of laboratory testing, mistakes occur more frequently before (pre-analytical) and after (post-analytical) the test has been performed. Most errors are due to pre-analytical factors (46-68.2% of total errors), while a high error rate (18.5-47% of total errors) has also been found in the post-analytical phase. Errors due to analytical problems have been significantly reduced over time, but there is evidence that, particularly for immunoassays, interference may have a serious impact on patients. A description of the most frequent and risky pre-, intra- and post-analytical errors and advice on practical steps for measuring and reducing the risk of errors is therefore given in the present paper. Many mistakes in the Total Testing Process are called "laboratory errors", although these may be due to poor communication, action taken by others involved in the testing process (e.g., physicians, nurses and phlebotomists), or poorly designed processes, all of which are beyond the laboratory's control. Likewise, there is evidence that laboratory information is only partially utilized. A recent document from the International Organization for Standardization (ISO) recommends a new, broader definition of the term "laboratory error" and a classification of errors according to different criteria. In a modern approach to total quality, centered on patients' needs and satisfaction, the risk of errors and mistakes

Laboratory automation proposes to improve the quality and efficiency of laboratory operations, and may provide a solution to the quality demands and staff shortages faced by today's clinical laboratories. Several vendors offer automation systems in the United States, with both subtle and obvious differences. Arriving at a decision to automate, and the ensuing evaluation of available products, can be time-consuming and challenging. Although considerable discussion concerning the decision to automate has been published, relatively little attention has been paid to the process of evaluating and selecting automation systems. To outline a process for evaluating and selecting automation systems as a reference for laboratories contemplating laboratory automation. Our Clinical Chemistry Laboratory staff recently evaluated all major laboratory automation systems in the United States, with their respective chemistry and immunochemistry analyzers. Our experience is described and organized according to the selection process, the important considerations in clinical chemistry automation, decisions and implementation, and we give conclusions pertaining to this experience. Including the formation of a committee, workflow analysis, submitting a request for proposal, site visits, and making a final decision, the process of selecting chemistry automation took approximately 14 months. We outline important considerations in automation design, preanalytical processing, analyzer selection, postanalytical storage, and data management. Selecting clinical chemistry laboratory automation is a complex, time-consuming process. Laboratories considering laboratory automation may benefit from the concise overview and narrative and tabular suggestions provided.

Hemostasis is a delicate, dynamic and intricate system, in which pro- and anti-coagulant forces cooperate for either maintaining blood fluidity under normal conditions, or else will prompt blood clot generation to limit the bleeding when the integrity of blood vessels is jeopardized. Excessive prevalence of anticoagulant forces leads to hemorrhage, whereas excessive activation of procoagulant forces triggers excessive coagulation and thrombosis. The hemostasis laboratory performs a variety of first, second and third line tests, and plays a pivotal role in diagnostic and monitoring of most hemostasis disturbances. Since the leading targets of Clinical Chemistry and Laboratory Medicine include promotion of progress in fundamental and applied research, along with publication of guidelines and recommendations in laboratory diagnostics, this journal is an ideal source of information on current developments in the laboratory technology of hemostasis, and this article is aimed to celebrate some of the most important and popular articles ever published by the journal in the filed of laboratory hemostasis.

The purpose of this paper is to illustrate a service quality framework that enhances service delivery in clinical laboratories by gauging medical practitioner satisfaction and by providing avenues for continuous improvement. The case study method has been used for conducting the exploratory study, with focus on the Mauritian public clinical laboratory. A structured questionnaire based on the SERVQUAL service quality model was used for data collection, analysis and for the development of the service quality framework. The study confirms the pertinence of the following service quality dimensions within the context of clinical laboratories: tangibility, reliability, responsiveness, turnaround time, technology, test reports, communication and laboratory staff attitude and behaviour. The service quality framework developed, termed LabSERV, is vital for clinical laboratories in the search for improving service delivery to medical practitioners. This is a pioneering work carried out in the clinical laboratory sector in Mauritius. Medical practitioner expectations and perceptions have been simultaneously considered to generate a novel service quality framework for clinical laboratories.

Outpatients enrolled in the STAR*D trial completed the Psychiatric Diagnostic Screening Questionnaire (PDSQ). An a priori 90% specificity threshold was set for PDSQ responses to ascertain the presence of 11 different concurrent DSM-IV Axis I disorders. Of 1376 outpatients, 38.2% had no concurrent comorbidities, while 25.6% suffered one, 16.1% suffered two, and 20.2% suffered three or more comorbid conditions. Altogether, 29.3% met threshold for social anxiety disorder, 20.8% for generalized anxiety disorder, 18.8% for posttraumatic stress disorder, 12.4% for bulimia, 11.9% for alcohol abuse/dependence, 13.4% for obsessive-compulsive disorder, 11.1% for panic disorder, 9.4% for agoraphobia, 7.3% for drug abuse/dependence, 3.7% for hypochondriasis, and 2.2% for somatoform disorder. Those with more concurrent Axis I conditions had earlier ages at first onset of MDD, longer histories of MDD, greater depressive symptom severity, more general medical comorbidity (even though they were younger than those with fewer comorbid conditions), poorer physical and mental function, health perceptions, and life satisfaction; and were more likely to be seen in primary care settings. Participants had to meet entry criteria for STAR*D. Ascertainment of comorbid conditions was not based on a structured interview. Concurrent Axis I conditions (most often anxiety disorders) are very common with MDD. Greater numbers of concurrent comorbid conditions were associated with increased severity, morbidity, and chronicity of their MDD.

The psychiatric ward is a place where all forms of violence are treated. Occasionally, this violence involves acts of aggression between patients in emergency psychiatric units or hospital wards. Such events can lead to the development or worsening of posttraumatic stress disorder. To establish the context, we first examined the epidemiology data concerning posttraumatic stress disorder in psychiatric patients who were frequently exposed to assaults. Secondly, we examined the issue of sexual and physical assaults between patients receiving treatment in a psychiatric ward. In this context, we studied possible occurrence of posttraumatic stress disorder associated with exposure to assaults of this kind. In certain cases, potentially traumatic exposure to violence was unknown to the medical staff or not taken into consideration. This would induce a risk of later development of posttraumatic stress disorder that would not be treated during the stay in psychiatry. To date, few scientific studies have focused on the proportion of patients assaulted by other patients during treatment in a psychiatric ward and the subsequent development of peritraumatic reactions and/or posttraumatic stress disorder associated with these assaults. We know that an insufficient number of public and private health institutions report the existence of such facts to the competent authorities. Also, a minority of clinicians and caregivers are trained in screening and management of trauma victims. Yet, these issues are particularly relevant in the scope of public health and health promotion. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Clinical laboratories in university hospitals should be operated with a good balance of medical practice, education, research, and management. The role of a clinical laboratory is to promptly provide highly reliable laboratory data to satisfy the needs of clinicians involved in medical practice and health maintenance of patients. Improvement and maintenance of the quality of the laboratory staff and environment are essential to achieve this goal. In order to implement these requirements efficiently, an appropriate quality management system should be introduced and established, and evaluated objectively by a third party (e.g. by obtaining ISO 15189 certification). ISO 15189 is an international standard regarding the quality and competence of clinical laboratories, and specifies a review of the efficient operational system and technical requirements such as competence in implementing practical tests and calibration. This means the results of laboratory tests reported by accredited laboratories withstand any international evaluation, which is very important to assure the future importance of the existence and management of clinical laboratories as well as internationalization of medical practice. "Education" and "research" have important implications in addition to "medical practice" and "management", as the roles that clinical laboratories should play in university hospitals. University hospital laboratories should be operated by keeping these four factors in good balance. Why are "education" and "research" required in addition to "medical practice" services? If individual clinical laboratory technologists can provide an appropriate response to this question, the importance of the existence of clinical laboratories would be reinforced, without being compromised.
Congress occasionally passes new laws that affect how clinical laboratories handle test orders from physicians and, subsequently, process the billing for tests. Once a bill is signed into law, it is forwarded to administrative agencies, which draft regulations and administrative procedures, under which the intentions of Congress are carried out. In the case of laboratory test ordering and billing, the Centers for Medicare and Medicaid Services (CMS) has the greatest influence over how these regulations and procedures are defined. Unfortunately, in many cases, billing rules have been promulgated in ways that create the need for hospitals and commercial laboratories to expend huge sums of money to bill within the confines of the administrative rules; cause clinical laboratories to suffer from omissions and mistakes of other parties who are part of the patient care process but are not accountable for the billing information they provide to laboratories; and, frankly, in some respects, simply defy common sense.

Clinical laboratories are significant generators of infectious waste, including microbiological materials, contaminated sharps, and pathologic wastes such as blood specimens and blood products. Most waste produced in laboratories can be disposed of in the general solid waste stream. However, improper management of infectious waste, including mixing general wastes with infectious wastes and improper handling or storage, could lead to disease transmission. The aim of this study was to assess waste management processes used at clinical laboratories in Shiraz, Iran. One hundred and nine clinical laboratories participated In this cross sectional study, Data collection was by questionnaire and direct observation. Of the total amount of waste generated, 52% (by weight) was noninfectious domestic waste, 43% was non-sharps infectious waste and 5% consisted of sharps. There was no significant relationship between laboratory staff or manager education and the score for quality of waste collection and disposal at clinical laboratories. Improvements in infectious waste management processes should involve clearer, more uniformly accepted definitions of infectious waste and increased staff training.

Clinical laboratories provide an invaluable service to millions of people around the world in the form of quality diagnostic care. Within the clinical laboratory industry the impetus for change has come from technological development (miniaturization, nanotechnology, and their collective effect on point-of-care testing; POCT) and the increasingly global nature of laboratory services. Potential technological gains in POCT include: the development of bio-sensors, microarrays, genetics and proteomics testing, and enhanced web connectivity. In globalization, prospective opportunities lie in: medical tourism, the migration of healthcare workers, cross-border delivery of testing, and the establishment of accredited laboratories in previously unexplored markets. Accompanying these impressive opportunities are equally imposing challenges. Difficulty transitioning from research to clinical use, poor infrastructure in developing countries, cultural differences and national barriers to global trade are only a few examples. Dealing with the issues presented by globalization and the impact of developing technology on POCT, and on the clinical laboratory services industry in general, will be a daunting task. Despite such concerns, with appropriate countermeasures it will be possible to address the challenges posed. Future laboratory success will be largely dependent on one's ability to adapt in this perpetually shifting landscape.

Quality in laboratory medicine is often described as doing the right test at the right time for the right person. Laboratory processes currently operate under the oversight of an accreditation body which gives confidence that the process is good. However, there are aspects of quality that are not measured by these processes. These are largely focused on ensuring that the most clinically appropriate test is performed and interpreted correctly. Clinical quality indicators were selected through a two-phase process. Firstly, a series of focus groups of clinical scientists were held with the aim of developing a list of quality indicators. These were subsequently ranked in order by an expert panel of primary and secondary care physicians. The 10 top indicators included the communication of critical results, comprehensive education to all users and adequate quality assurance for point-of-care testing. Laboratories should ensure their tests are used to national standards, that they have clinical utility, are calibrated to national standards and have long-term stability for chronic disease management. Laboratories should have error logs and demonstrate evidence of measures introduced to reduce chances of similar future errors. Laboratories should make a formal scientific evaluation of analytical quality. This paper describes the process of selection of quality indicators for laboratory medicine that have been validated sequentially by deliverers and users of the service. They now need to be converted into measureable variables related to outcome and validated in practice.
Laboratory medicine has undergone a sea change, and medical laboratories must now adapt to, and meet new, customer-supplier needs springing from shifts in the patterns of disease prevalence, medical practice, and demographics. Managed care and other cost-containment processes have forced those involved in health care to cooperate to develop a full picture of patient care, and this has affected clinical laboratory objectives, the main focus now being on improvement in medical outcomes. More recently, the resource shortages in health care and results of cost/effectiveness analysis have demonstrated that the value of a laboratory test must be ascertained not only on the basis of its chemical or clinical performance characteristics, but also by its impact on patient management, the only true assessment of the quality of testing being quality of patient outcomes. The time is ripe for changing the vision of laboratory medicine, and some of the reasons for this are the availability of results in real-time, the introduction of more specific tests, and the trend to prevent diseases rather than cure them. The information from laboratory tests designed to evaluate biochemical or genetic risk and/or prognostic factors cannot be replaced either by physical examination and/or the assessment of symptoms. Today, the importance of laboratory scientists must be proven in three broad areas: a) guaranteeing the quality of tests, irrespective of where they are performed; b) improving the quality of the service; c) maximizing the impact of laboratory information on patient management.
Laboratory services around the world are undergoing substantial consolidation and changes through mechanisms ranging from mergers, acquisitions and outsourcing, primarily based on expectations to improve efficiency, increasing volumes and reducing the cost per test. However, the relationship between volume and costs is not linear and numerous variables influence the end cost per test. In particular, the relationship between volumes and costs does not span the entire platter of clinical laboratories: high costs are associated with low volumes up to a threshold of 1 million test per year. Over this threshold, there is no linear association between volumes and costs, as laboratory organization rather than test volume more significantly affects the final costs. Currently, data on laboratory errors and associated diagnostic errors and risk for patient harm emphasize the need for a paradigmatic shift: from a focus on volumes and efficiency to a patient-centered vision restoring the nature of laboratory services as an integral part of the diagnostic and therapy process. Process and outcome quality indicators are effective tools to measure and improve laboratory services, by stimulating a competition based on intra- and extra-analytical performance specifications, intermediate outcomes and customer satisfaction. Rather than competing with economic value, clinical laboratories should adopt a strategy based on a set of harmonized quality indicators and performance specifications, active laboratory stewardship, and improved patient safety.

Currently, the diagnosis of psychiatric illnesses is based upon DSM-5 criteria. Although endophenotype-specificity for a particular disorder is discussed, the identification of objective biomarkers is ongoing for aiding diagnosis, prognosis, or clinical response to treatment. We need to improve the understanding of the biological abnormalities in psychiatric illnesses across conventional diagnostic boundaries. The present review investigates the innovative post-genomic knowledge used for psychiatric illness diagnostics and treatment response, with a particular focus on proteomics. Areas covered: This review underlines the contribution that psychiatric innovative biomarkers have reached in relation to diagnosis and theragnosis of psychiatric illnesses. Furthermore, it encompasses a reliable representation of their involvement in disease through proteomics, metabolomics/pharmacometabolomics and lipidomics techniques, including the possible role that gut microbiota and CYP2D6 polimorphisms may play in psychiatric illnesses. Expert opinion: Etiologic heterogeneity, variable expressivity, and epigenetics may impact clinical manifestations, making it difficult for a single measurement to be pathognomonic for multifaceted psychiatric disorders. Academic, industry, or government's partnerships may successfully identify and validate new biomarkers so that unfailing clinical tests can be developed. Proteomics, metabolomics, and lipidomics techniques are considered to be helpful tools beyond neuroimaging and neuropsychology for the phenotypic characterization of brain diseases.

SUMMARY In this review we examine the literature related to emerging technologies that will help to reshape the clinical microbiology laboratory. These topics include nucleic acid amplification tests such as isothermal and point-of-care molecular diagnostics, multiplexed panels for syndromic diagnosis, digital PCR, next-generation sequencing, and automation of molecular tests. We also review matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) and electrospray ionization (ESI) mass spectrometry methods and their role in identification of microorganisms. Lastly, we review the shift to liquid-based microbiology and the integration of partial and full laboratory automation that are beginning to impact the clinical microbiology laboratory. PMID:25278575

Approximately half of all patients presenting to dermatologists exhibit signs and symptoms of psychiatric conditions that are either primary or secondary to cutaneous disease. Because patients typically resist psychiatric consult, dermatologists often are on the front line in evaluating and treating these patients. Accordingly, distinguishing the specific underlying or resulting psychiatric condition is essential for effective treatment. The etiology, epidemiology, clinical presentation, diagnosis, and first-line treatment of specific primary psychiatric causes of dermatologic conditions, including delusional infestation, Morgellons syndrome, olfactory reference syndrome, body dysmorphic disorder, excoriation disorder, trichotillomania, and dermatitis artefacta are discussed here, followed by a discussion of the recommended treatment approach with an overview of the different first-line therapies discussed in this review, specifically cognitive behavioral therapy, atypical antipsychotics, selective serotonin reuptake inhibitors, and tricyclic antidepressants. Included is a guide for dermatologists to use while prescribing these medications.
Full Text Available Background: Autism Spectrum Disorder (ASD is an early neurodevelopmental disorder that accompanies the individual throughout life. There is a significant clinical overlap of ASD with other psychiatric disorders including personality disorders, psychotic disorders, obsessive-compulsive disorder and depression. Additionally, the presence of high rates of psychiatric comorbidity, often with atypical presentations, delays the ASD diagnosis and makes it more difficult to manage. Aims: To illustrate the complexity of ASD diagnosis and approach in adults. Methods: Report of a clinical case and review of the literature. Results and Conclusion: This paper presents the case of a 46-year-old patient, with ASD, with a long history of interpersonal difficulties and psychiatric symptomatology. Over the years, different diagnoses have been made, particularly schizoid and schizotypal personality disorders, psychosis not otherwise specified and paranoid schizophrenia, which led to poor adherence to treatment, and prevented a full understanding of the patient’s clinical presentation and lifelong struggles.

A women's psychiatric clinic, incorporated within a university teaching general hospital and staffed entirely by women, was opened in March of 1980. The authors studied a sample of 100 women who came to the clinic and characterized them by demographic variables, psychiatric diagnoses, health problems, chronic illness, death in the family, and traumatic incidents. Death in the family before she was 18 was found to predict a woman's subsequent request for or completion of sterilization. Physical or sexual abuse was significantly related to abortion, and abortion and trauma were significantly correlated.

No study has assessed psychiatric disorders among infertile men and women seeking fertility treatment in Saudi Arabia. Therefore, we sought to measure the rate of psychiatric disorders in this population. This was a cross-sectional observational study among patients attending infertility clinics at three referral hospitals in Riyadh, Saudi Arabia, between January 2013 and September 2014. 406 patients (206 women and 200 men) participated in the study. The approved Arabic version of the MINI tool was used to assess 18 common psychiatric illnesses. The response rate was 81%. Of the men surveyed, only 4.5% self-reported having a psychiatric disorder. Of the women surveyed, only 10.2% reported having a psychiatric disorder. However, using the MINI scale, psychiatric illness was documented in 30% of males and 36.9% of females. The most common diagnoses for both genders were depression (21.7%) and anxiety (21.2%). Significantly more females than males exhibited suicidality and depression. In contrast, significantly more males than females had bipolar disorders and substance-related disorders. A low monthly income among male and female participants and polygamy among female participants were significantly associated with psychiatric disorders. This study shows that a higher prevalence of psychiatric disorders, particularly depression and anxiety, among infertile men and women in Saudi Arabia is associated with lower income and polygamy. This study highlights the importance of integrated care for alleviating the psychological burden of this unfortunate population and improving outcomes and quality of life. This study also encourages follow-up studies that aim to further understand the complex relationship between fertility and psychological well-being.

Brain single photon emission computed tomography (SPECT) is a well-established and reliable method to assess brain function through measurement of regional cerebral blood flow (rCBF). It can be used to define a patient's pathophysiological status when neurological or psychiatric symptoms cannot be explained by anatomical neuroimaging findings. Though there is ample evidence validating brain SPECT as a technique to track human behavior and correlating psychiatric disorders with dysfunction of specific brain regions, only few psychiatrists have adopted brain SPECT in routine clinical practice. It can be utilized to evaluate the involvement of brain regions in a particular patient, to individualize treatment on basis of SPECT findings, to monitor the treatment response and modify treatment, if necessary. In this article, we have reviewed the available studies in this regard from existing literature and tried to present the evidence for establishing the clinical role of brain SPECT in major psychiatric illnesses

Eating disorders (EDs) have been underdiagnosed in many clinical settings. This study investigates the influence of clinical characteristics on presenting symptoms of patients with EDs. Psychiatric outpatients, aged 18-45, were enrolled sequentially and received a two-phase survey for EDs in August 2010-January 2013. Their primary reasons for seeking psychiatric help were obtained at their first encounter with outpatient psychiatrists. Patients' clinical and demographic characteristics were compared according to presenting symptoms with or without eating/weight problems. Of 2140 patients, 348 (16.3%) were diagnosed with an ED (22.6% of women and 6.3% of men). The three most common reasons for seeking psychiatric help were eating/weight problems (46.0%), emotional problems (41.3%), and sleep disturbances (19.3%). The multivariate analyses suggest that when patients with EDs presented symptoms that were less related to eating/weight problems, they were significantly more likely to be those having diagnoses other than anorexia nervosa or bulimia nervosa and less severe degree of binge-eating. Further, patients with EDs who demonstrated more impulsive behaviors and poorer functioning were less likely to report their eating problems when visiting psychiatric clinics. Thus, ED should be assessed routinely in patients with complex psychopathology to facilitate comprehensive treatment. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available ABSTRACT CONTEXT: An almost 50% prevalence of psychiatric disorders among cancer patients has prompted a series of studies on consultation-liaison psychiatry. Nonetheless, there are few reports on the epidemiological factors involving comorbidity between cancer and psychiatric disorders. OBJECTIVE: To evaluate the epidemiological profile of cancer inpatients referred to the consultation-liaison psychiatric service in an oncology hospital during its first year of activity. TYPE OF STUDY: Descriptive study. SETTING: Tertiary-care teaching hospital. PARTICIPANTS: 319 patients referred 412 times to the consultation-liaison psychiatry service. PROCEDURES: From August 97 to July 98, an appraisal was made of data on all admissions registered at the Hospital do Câncer, and also all referrals registered at the consultation-liaison psychiatry service. MAIN MEASUREMENTS: The demographics and patients' clinical data, the type and flow of the request, and the evaluation conducted by the service were analyzed and comparisons with the hospital data were made. The distribution of the number of referrals was used to construct a profile of patients who had repeatedly used the service. RESULTS: Psychiatric diagnoses were found in 59% of the cases. Forty-three percent of these required medication, 18.3% needed psychotherapy, 22.1% family intervention and 20.5% guidance from the staff. Over 22.8% of the consultations were reevaluations, mainly involving younger male patients with worst prognoses. These patients required lengthier and more elaborate intervention, and had higher prevalence of depressive and behavioral disorders. CONCLUSION: A younger and mainly male population of non-surgical oncological cases was referred to the consultation-liaison psychiatric service during its first year of activity. The psychiatric disorder prevalence was higher than expected, and consisted predominantly of mood disorders. We detected a priority group, namely the reevaluated

The objective was to estimate the prevalence of psychiatric morbidity amongst patients attending Mobile Health Clinic (MHC) in an urban community in South Delhi. Adult subjects were recruited by systematic random sampling at outpatient MHC. Primary Care Evaluation of Mental Disorder Patient Health Questionnaire (PHQ) was used for screening, and Mini International Neuropsychiatric Interview (M.I.N.I.) was used for the confirmation of diagnosis of psychiatric disorder of all PHQ-positive and 20% of PHQ-negative patients. Association of selected sociodemographic factors with psychiatric morbidity was also assessed. In total, 350 subjects were recruited, out of which 92 (26.3%) [95% confidence interval (CI) 21.7-31.0] were found to be PHQ positive. M.I.N.I. was administered to 141 subjects (92 PHQ positives and 52 PHQ negatives). Total estimated magnitude of psychiatric morbidity by M.I.N.I. was 25.4% (95% CI 20.9-29.9). Depression (15.7%) was observed to be the most common psychiatric disorder followed by generalized anxiety disorder (11.1%) and phobic disorders (10.1%). Suicidal ideation was reported by 37 (10.6%) patients. Literate status [odds ratio (OR)=0.43] and duration of migration >20 years to study area (OR=1.27) were found to be significantly associated with psychiatric morbidity. In resource-poor country like India, high psychiatric morbidity at MHC justifies the use of MHC for providing outreach mental health services in difficult areas. Copyright Â© 2012 Elsevier Inc.

Because of their special physical and chemical properties, the adrenal secretory products were among the first hormonal substances to be measured by methods other than bioassay. Over the past several years, the development of sensitive and specific methods of hormone assay dependent on the use of radionuclides has revolutionized investigative and clinical endocrinology. While the capacity of defining most abnormalities of adrenal function antedates hormone measurement and adrenal imaging utilizing radioisotopes, the availability of such methods has greatly facilitated and made more precise the diagnostic approach to patients with suspected adrenal dysfunction. As an example of how clinical and laboratory considerations can be integrated into a rational approach to the diagnosis of adrenal disease, the problem of suspected adrenal hyperfunction is analyzed in light of current understanding of its pathophysiology. Reflection demonstrates that suspected primary aldosteronism and adrenal insufficiency are equally amenable to such an approach

Clinicians' attention is a precious resource, which in the current healthcare practice is consumed by the cognitive demands arising from complex patient conditions, information overload, time pressure, and the need to aggregate and synthesize information from disparate sources. The ability to organize information in ways that facilitate the generation of effective diagnostic solutions is a distinguishing characteristic of expert physicians, suggesting that automated systems that organize clinical information in a similar manner may augment physicians' decision-making capabilities. In this paper, we describe the design and evaluation of a theoretically driven cognitive support system (CSS) that assists psychiatrists in their interpretation of clinical cases. The system highlights, and provides the means to navigate to, text that is organized in accordance with a set of diagnostically and therapeutically meaningful higher-level concepts. To evaluate the interface, 16 psychiatry residents interpreted two clinical case scenarios, with and without the CSS. Think-aloud protocols captured during their interpretation of the cases were transcribed and analyzed qualitatively. In addition, the frequency and relative position of content related to key higher-level concepts in a verbal summary of the case were evaluated. In addition the transcripts from both groups were compared to an expert derived reference standard using latent semantic analysis (LSA). Qualitative analysis showed that users of the system better attended to specific clinically important aspects of both cases when these were highlighted by the system, and revealed ways in which the system mediates hypotheses generation and evaluation. Analysis of the summary data showed differences in emphasis with and without the system. The LSA analysis suggested users of the system were more "expert-like" in their emphasis, and that cognitive support was more effective in the more complex case. Cognitive support impacts

The healthcare sector is an important contributor to mercury (Hg) pollution because of the potential presence of mercury in thermometers, blood pressure cuffs, amalgams, etc. There are also other potential sources of mercury in this sector which are used frequently and in high volumes where the presence of the metal is not obvious and which might be collectively contributing to pollution. For instance, some chemicals used for the clinical diagnosis of illness may contain mercury. The goal of this study was to investigate potential sources of mercury pollution, which originate from clinical laboratory discharges, using an exploratory approach. The focus was on the residue generated during automatic analysis of patients' bodily fluids at a medical center in Hermosillo, Sonora, Mexico. This study shows an overview of what might be happening in the region or the country related to non-obvious sources of mercury in the healthcare sector. The results showed measurable levels of mercury in the residues coming from urine sediment analysis. These amounts do not exceed the maximum allowed by Mexican environmental regulations; nevertheless, the frequency and cumulative volume of residues generated, combined with the potential for persistence and the bioaccumulation of mercury in the environment, warrant attention. The work carried out in this study is being taken as a model for future studies for pollution prevention in the healthcare sector with the goal of measuring mercury emissions to the environment from clinical laboratory wastewater, including identifying sources which--while not obvious--could be important given the frequency and volume of their use in the clinical diagnosis.

Full Text Available OBJECTIVE: To evaluate clinically, and with laboratory, tests, women with polycystic ovary syndrome (PCO. PATIENTS: One hundred and twelve women with PCO were studied. METHODS: The following data was recorded: Current age; age at menarche; menstrual irregularity, occurrence of similar cases in the family; fertility, obstetric history; body mass index (BMI; and presence of hirsutism. Serum measurements of follicle stimulating hormone (FSH, luteinizing hormone (LH, prolactin, free testosterone, and dehydroepiandrosterone sulfate were taken. RESULTS: All patients presented either oligomenorrhea (31 percent, periods of secondary amenorrhea (9 percent, or both alterations (60 percent. The majority of the patients were infertile (75.6 percent. The LH/FSH ratio was higher than 2:1 in 55 percent of the patients and higher than 3:1 in 26.2 percent. The ultrasonographic aspect of the ovaries was considered to be normal in 31 percent. CONCLUSION: The main clinical feature of the PCO is the irregularity of menses since menarche, and that the laboratory tests would be important to exclude other disorders such as hyperprolactinemia or hyperandrogenemia caused by late-onset congenital adrenal hyperplasia.

To implement and evaluate the care zoning model in an eight-bed psychiatric intensive care unit and, specifically, to examine the model's ability to improve the documentation and communication of clinical risk assessment and management. Care zoning guides nurses in assessing clinical risk and planning care within a mental health context. Concerns about the varying quality of clinical risk assessment prompted a trial of the care zoning model in a psychiatric intensive care unit within a regional mental health facility. The care zoning model assigns patients to one of 3 'zones' according to their clinical risk, encouraging nurses to document and implement targeted interventions required to manage those risks. An implementation trial framework was used for this research to refine, implement and evaluate the impact of the model on nurses' clinical practice within the psychiatric intensive care unit, predominantly as a quality improvement initiative. The model was trialled for three months using a pre- and postimplementation staff survey, a pretrial file audit and a weekly file audit. Informal staff feedback was also sought via surveys and regular staff meetings. This trial demonstrated improvement in the quality of mental state documentation, and clinical risk information was identified more accurately. There was limited improvement in the quality of care planning and the documentation of clinical interventions. Nurses' initial concerns over the introduction of the model shifted into overall acceptance and recognition of the benefits. The results of this trial demonstrate that the care zoning model was able to improve the consistency and quality of risk assessment information documented. Care planning and evaluation of associated outcomes showed less improvement. Care zoning remains a highly applicable model for the psychiatric intensive care unit environment and is a useful tool in guiding nurses to carry out routine patient risk assessments. © 2013 John Wiley & Sons

Increasingly these data are being integrated with other data to inform health system-wide actions meant to improve diagnostic test utilization, service efficiency, and "meaningful use." The Academy of Clinical Laboratory Physicians and Scientists hosted a satellite meeting on clinical laboratory analytics in conjunction with their annual meeting on May 29, 2014 in San Francisco. There were 80 registrants for the clinical laboratory analytics meeting. The meeting featured short presentations on current trends in clinical laboratory analytics and several panel discussions on data science in laboratory medicine, laboratory data and its role in the larger healthcare system, integrating laboratory analytics, and data sharing for collaborative analytics. One main goal of meeting was to have an open forum of leaders that work with the "big data" clinical laboratories produce. This article summarizes the proceedings of the meeting and content discussed.

Full Text Available Objective To study socio-demographic and clinical aspects, as well as psychiatric co-morbidity that influence the quality of life of adult epileptic patients. Methods One hundred and thirty-two individuals diagnosed with epilepsy were evaluated from neurological/clinical and psychiatric points of view and by the Quality of Life in Epilepsy Inventory (QOLIE-31. Predictive factors for the QOLIE-31 scores were studied. Results The regression analyses indicated the existence of psychiatric co-morbidity (total score, seizure worry, emotional well-being, energy/fatigue, social function and cognitive function and a greater seizure frequency (total score, cognitive function and energy/fatigue as predictive factors for lower scores in the total QOLIE-31 score and in various dimensions. Abnormalities in the neurological exam and poly-therapy with anti-epileptic drugs were negative factors limited to one of the dimensions cognitive function and social function, respectively. Conclusion The presence of psychiatric co-morbidity and a greater seizure frequency were the main factors influencing the quality of life in epileptic patients as evaluated by QOLIE-31.

In psychiatric-mental health, creating an innovative strategy to help students learn content that may not be frequently seen in a clinical setting is challenging. Thus, simulation helps narrow this gap. Using Kirkpatrick and Kirkpatrick's model of evaluation to guide the current study, faculty contacted baccalaureate nursing program graduates who completed a psychiatric-mental health clinical simulation scenario featuring a hanging suicide and wrist cutting suicide attempt scenario in the "Behind the Door" series as part of the clinical component of their undergraduate psychiatric-mental health course. Eleven nurses responded to a survey regarding their post-graduate encounters with these types of clinical situations, and their perception of recall and application of knowledge and skills acquired during the simulation experience to the clinical situation. Nursing graduates' responses are expressed through three major themes: emotional, contextual/behavioral, and assessment outcomes. Data from the survey indicate that nursing graduates perceived the "Behind the Door" simulations as beneficial to nursing practice. This perception is important in evaluating knowledge transfer from a simulation experience as a student into application in nursing practice.

Few studies have focused the association between bullying and psychiatric disorders in clinical samples. The aim of this study was to examine if bullying behaviour was associated with psychiatric disorders and school well-being. The cross-sectional study was part of a health survey at St. Olav's University Hospital. The sample consisted of 685 adolescent patients aged 13-18 years who completed an electronic questionnaire. Clinical diagnoses were collected from clinical records. In this clinical psychiatric sample, 19% reported being bullied often or very often, and 51% reported being bullied from time to time. Logistic regression analyses showed associations between being a victim and having a mood disorder, and between being involved in bullying behaviour and reporting lower scores on school well-being. No difference was found in bullying behaviour on gender, age and SES. The risk of being a victim was high among adolescents in this clinical sample, especially among patients with mood disorders. Any involvement in bullying behaviour was associated with reduced school well-being.

In this study we aimed to investigate the prevalance and clinical correlations of night eating syndrome (NES) in a sample of psychiatric outpatients. Four hundred thirthy three consecutive psychiatric out-patients older than 18years were evaluated in the outpatient clinics using clinical interview according to the DSM-IV with regard to psychiatric diagnosis. Participants were also screened for presence of NES utilizing both clinical interview and self report based on Night Eating Questionnaire (NEQ) instruments. Sociodemographic and clinical features such as age, gender, education level, socioeconomic level and body mass index (BMI) were also recorded. The Body Shape Questionnaire (BSQ) and the Symptom Checklist-90 Revised (SCL-90R) were administered. Based on the proposed diagnostic criteria of the NES via utilizing clinical interview method, 97 (32 male, 65 female) of the sample met diagnostic criteria for NES. The point prevalence of NES was 22.4%. No statistically significant differences were found between the two groups in terms of age, gender, marital status, education and BMI. The patients with NES had higher NEQ, BSQ and SCL-90R subscale scores than patients without NES. Prevalance of depressive disorder, impulse control disorder, and nicotine dependency was higher among patients with NES. No differences were found with regard to the medication (antipsychotics, antidepressants and mood stabilizers). Night eating syndrome is prevalent among psychiatric outpatients and associated with depression, impulse control disorder, and nicotine dependency. Body dissatisfaction and higher symptom severity are also other risk factors for the development of NES. Copyright © 2014 Elsevier Inc. All rights reserved.

Haemolysis is usually caused by inadequate specimen collection or preanalytical handling and is suggested to be a suitable indicator of preanalytical quality. We investigated the prevalence of detectable haemolysis in all routine venous blood samples in OPDs and IPDs to identify differences in preanalytical quality. Haemolysis index (HI) values were obtained from a Vitros 5,1 in the routine clinical chemistry laboratory for samples collected in the outpatient department (OPD) collection centres, a hospital, and inpatient departments (IPD). Haemolysis was defined as a HI > or = 15 (detection limit). Samples from the OPD with the highest prevalence of haemolysis were 6.1 times (95% confidence interval (CI) 4.0 - 9.2) more often haemolysed compared to the center with the lowest prevalence. Of the samples collected in primary health care, 10.4% were haemolysed compared to 31.1% in the IPDs (p = 0.001). A notable difference in haemolysed samples was found between the IPDs section staffed by emergency medicine physicians and the section staffed by primary health care physicians (34.8% vs. 11.3%, p = 0.001). The significant variation in haemolysis indices among the investigated units is likely to reflect varying preanalytical conditions. The HI is a valuable tool for estimation and follow-up of preanalytical quality in the health care laboratory.
In the clinical-chemical laboratory, the problems of the personal radiation protection can be handled relatively simply. Important conditions are certain requirements as far as the building is concerned and the keeping to protection measures to invoid ingestion, inhalation, and resorption of open radioactive substances. Very intensive attention must be paid to a clean working technique in order to be able to exclude the danger of contamination which is very disturbing during the extremely sensitive measurements. The higgest problem in the handling of open radioactive substances, however, is in our opinion the waste management because it requires which space and personnel this causing high costs. Furthermore, since 1 January 1979, the permission for the final storage of radioactive waste in the shut down mine ASSE was taken back from the county collection places and it cannot be said yet if and when this permission will be given again.

Opposite to clinical laboratory findings in experimental drowning of animals (erythrocytic lysis, hyperkalemia, and final cardial fibrillation) are the observations in drowned humans (increase of pCO2, hypoxic encephalopathy), which leads to a different pathophysiological interpretation of the drowning process. This process, however, is recently discussed again, therefore an additional study seemed to be recommended. In a retrospective study, 31 cases of near-drowning (23 cases: fresh water; 8 cases: brackish water) clinical laboratory data were analysed. While 21 of the cases were fatal with a delay of up to 180 days, 10 individuals survived the accident, four cases with severe neurological deficits. Data of pH, potassium, sodium, chloride, hemoglobin and total protein were collected during the very early post-drowning period. Nearly all cases (96%) revealed a reduction of pH due to hypoxic acidosis, and only two cases (6.5%) exhibited a slight hyperkalemia. The hemoglobin level was normal in most of the cases (83%) and slightly reduced in the others (17%) while the protein level was slightly reduced in most of the fatalities (80%). As a result of our investigation we have to state the lack of hyperkalemia as well as of an increase of the hemoglobin level indicate that there is no distinct intravascular red cell lysis due to influx of water into the vascular compartment. Therefore the death by drowning in humans in most cases is the result of a hypoxic cerebral process. A comparison with animal experiments obviously is not helpful because the drowning process in humans leads to an aspiration of only 2-4 ml water/kg, while in animal experiments more than 10 ml water/kg will be artificially aspirated leading to red cell lysis as well as to electrolyte disturbances and cardial fibrillation.

The focus on recovery for persons with severe and persistent mental illness is leading state psychiatric hospitals to transform their method of care delivery. This article describes a quality improvement project involving a hospital's administration and multidisciplinary state-university affiliation that collaborated in the development and implementation of a nursing care delivery model in a state psychiatric hospital. The quality improvement project team instituted a new model to promote the hospital's vision of wellness and recovery through utilization of the therapeutic relationship and greater clinical accountability. Implementation of the model was accomplished in 2 phases: first, the establishment of a structure to lay the groundwork for accountability and, second, the development of a mechanism to provide a clinical supervision process for staff in their work with clients. Effectiveness of the model was assessed by surveys conducted at baseline and after implementation. Results indicated improvement in clinical practices and client living environment. As a secondary outcome, these improvements appeared to be associated with increased safety on the units evidenced by reduction in incidents of seclusion and restraint. Restructuring of the service delivery system of care so that clients are the center of clinical focus improves safety and can enhance the staff's attention to work with clients on their recovery. The role of the advanced practice nurse can influence the recovery of clients in state psychiatric hospitals. Future research should consider the impact on clients and their perceptions of the new service models.

Burning mouth syndrome is a chronic and persistent painful condition characterized by burning sensation in the oral mucosa. We investigated the etiological factors of patients presented with the history of burning in the mouth who admitted our outpatient clinics over the 8-years period and who had no underlying identifiable local factors. We also tried to determine their demographic and clinical characteristics. Our aim was to investigate the association between burning mouth and psychiatric disorders such as depression and anxiety, chronic diseases like diabetes mellitus (DM) and other laboratory studies in patients complaining of solely burning in the mouth. The study included patients with the history of burning in mouth who presented in our outpatient clinic between 2005 and 2012. They were evaluated by a neurologist, a psychiatrist, an internist, and a dentist. Complete blood counts, biochemical analysis and cranial magnetic resonance imaging (MRI) were performed for all patients. A total of 26 (22 (84%) females, 4 (15%) males; mean age 55.9 years) patients were enrolled in this study. Five (19.2%) of the patients had depression, 2 (7.7%) had anxiety disorder, 2 (7.7%) had diabetes mellitus, 8 (30%) had B12 vitamin deficiency, 3 (11.5%) had decreased ferritin levels in blood, and 1 (3.8%) had folic acid deficiency. Cranial MRI of all patients were normal. Nine patients (34.6%) had no etiological causes. A multidisciplinary approach in the management of burning mouth and establishment of common criteria for the diagnosis would provide insight into the underlying pathophysiological mechanism.

Since the winter of 1999, the authors and their research team have been conducting clinical studies involving the administration of ayahuasca to healthy volunteers. The rationale for conducting this kind of research is twofold. First, the growing interest of many individuals for traditional indigenous practices involving the ingestion of natural psychotropic drugs such as ayahuasca demands the systematic study of their pharmacological profiles in the target species, i.e., human beings. The complex nature of ayahuasca brews combining a large number of pharmacologically active compounds requires that research be carried out to establish the safety and overall pharmacological profile of these products. Second, the authors believe that the study of psychedelics in general calls for renewed attention. Although the molecular and electrophysiological level effects of these drugs are relatively well characterized, current knowledge of the mechanisms by which these compounds modify the higher order cognitive processes in the way they do is still incomplete, to say the least. The present article describes the development of the research effort carried out at the Autonomous University of Barcelona, commenting on several methodological aspects and reviewing the basic clinical findings. It also describes the research currently underway in our laboratory, and briefly comments on two new studies we plan to undertake in order to further our knowledge of the pharmacology of ayahuasca.

Mental health problems of children are commonly treated by psychotherapy and other psychosocial treatments. Studies comparing different treatments in naturalistic clinical settings are few, however. We assessed the differences: 1) in symptoms and diagnoses; 2) in treatment outcome between psychotherapy and other psychosocial treatments; and 3) evaluated the effect of family background and life circumstances on the outcome. The data were collected from the psychiatric hospital records of Oulu University Hospital, Finland. All 118 children (aged psychotherapy from the Department of Child Psychiatry in 1996-2005 and 118 age- and sex-matched children undergoing other psychosocial treatments were included. A lack of later recorded psychiatric problems was used as an indicator of good treatment outcome. On referral, functional ability was severely impaired in almost half of the children (Children's Global Assessment Scale score psychotherapy group, while no difference was found in externalizing symptoms between the groups. In both groups, later psychiatric problems were associated with a child's low functional ability and poor parental coping with their responsibilities. Children with internalizing problems had impaired prognosis if they had psychosocial treatments other than psychotherapy. Individual psychotherapy should especially be considered for children with internalizing symptoms, but the outcome of psychiatric treatment depends not only on children's own functional abilities, but also on parental abilities.

Neurological and psychiatric disorders are characterized by several disabling symptoms for which effective, mechanism-based treatments remain elusive. Consequently, more advanced non-invasive therapeutic methods are required. A method that may modulate brain activity and be viable for use in clinical practice is repetitive transcranial magnetic stimulation (rTMS). It is a non-invasive procedure whereby a pulsed magnetic field stimulates electrical activity in the brain. Here, we focus on the basic foundation of rTMS, the main stimulation parametters, the factors that influence individual responses to rTMS and the experimental advances of rTMS that may become a viable clinical application to treat neurological and psychiatric disorders. The findings showed that rTMS can improve some symptoms associated with these conditions and might be useful for promoting cortical plasticity in patients with neurological and psychiatric disorders. However, these changes are transient and it is premature to propose these applications as realistic therapeutic options, even though the rTMS technique has been evidenced as a potential modulator of sensorimotor integration and neuroplasticity. Functional imaging of the region of interest could highlight the capacity of rTMS to bring about plastic changes of the cortical circuitry and hint at future novel clinical interventions. Thus, we recommend that further studies clearly determine the role of rTMS in the treatment of these conditions. Finally, we must remember that however exciting the neurobiological mechanisms might be, the clinical usefulness of rTMS will be determined by its ability to provide patients with neurological and psychiatric disorders with safe, long-lasting and substantial improvements in quality of life.

Full Text Available Abstract Background The PERSEO study (psychiatric emergency study and epidemiology is a naturalistic, observational clinical survey in Italian acute hospital psychiatric units, called SPDCs (Servizio Psichiatrico Diagnosi e Cura; in English, the psychiatric service for diagnosis and management. The aims of this paper are: (i to describe the epidemiological and clinical characteristics of patients, including sociodemographic features, risk factors, life habits and psychiatric diagnoses; and (ii to assess the clinical management, subjective wellbeing and attitudes toward medications. Methods A total of 62 SPDCs distributed throughout Italy participated in the study and 2521 patients were enrolled over the 5-month study period. Results Almost half of patients (46% showed an aggressive behaviour at admission to ward, but they engaged more commonly in verbal aggression (38%, than in aggression toward other people (20%. A total of 78% of patients had a psychiatric diagnosis at admission, most frequently schizophrenia (36%, followed by depression (16% and personality disorders (14%, and no relevant changes in the diagnoses pattern were observed during hospital stay. Benzodiazepines were the most commonly prescribed drugs, regardless of diagnosis, at all time points. Overall, up to 83% of patients were treated with neuroleptic drugs and up to 27% received more than one neuroleptic either during hospital stay or at discharge. Atypical and conventional antipsychotics were equally prescribed for schizophrenia (59 vs 65% during stay and 59 vs 60% at discharge, while atypical drugs were preferred in schizoaffective psychoses (72 vs 49% during stay and 70 vs 46% at discharge and depression (41 vs 32% during stay and 44 vs 25% at discharge. Atypical neuroleptics were slightly preferred to conventional ones at hospital discharge (52 vs 44%. Polypharmacy was in general widely used. Patient attitudes toward medications were on average positive and self

Individuals with psoriasis are at increased risk for psychiatric comorbidities, including suicidal ideation and behavior (SIB). To distinguish between the underlying risk and potential for treatment-induced psychiatric adverse events in patients with psoriasis being treated with brodalumab, a fully human anti-interleukin 17 receptor A monoclonal antibody. Data were evaluated from a placebo-controlled, phase 2 clinical trial; the open-label, long-term extension of the phase 2 clinical trial; and three phase 3, randomized, double-blind, controlled clinical trials (AMAGINE-1, AMAGINE-2, and AMAGINE-3) and their open-label, long-term extensions of patients with moderate-to-severe psoriasis. The analysis included 4464 patients with 9161.8 patient-years of brodalumab exposure. The follow-up time-adjusted incidence rates of SIB events were comparable between the brodalumab and ustekinumab groups throughout the 52-week controlled phases (0.20 vs 0.60 per 100 patient-years). In the brodalumab group, 4 completed suicides were reported, 1 of which was later adjudicated as indeterminate; all patients had underlying psychiatric disorders or stressors. There was no comparator arm past week 52. Controlled study periods were not powered to detect differences in rare events such as suicide. Comparison with controls and the timing of events do not indicate a causal relationship between SIB and brodalumab treatment. Copyright © 2017 American Academy of Dermatology, Inc.

There are no published data on insight in homeless patients with psychiatric disorders in China. This study examined insight in homeless and non-homeless Chinese psychiatric inpatients in relation to demographic and clinical variables. A total of 278 homeless and 222 non-homeless inpatients matched in age and gender were included in the study. Demographic and clinical characteristics were collected based on a review of medical charts and a clinical interview with standardized instruments. Insight was evaluated with the Insight and Treatment Attitudes Questionnaire. Altogether 20.5% of homeless inpatients and 43.7% of the non-homeless controls had good insight. Compared with homeless inpatients with impaired insight, homeless inpatients with good insight had higher physical quality of life, longer duration of illness and less severe positive and negative symptoms. Impaired insight appeared more common in homeless psychiatric inpatients in China. Further studies should address the need for effective therapeutic interventions that promote homeless patients' insight. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Laboratory-acquired infections due to nontyphoidal Salmonella are rare. Yet, recent outbreaks in microbiology teaching laboratories show that these species are still an appreciable occupational hazard for laboratory employees. This article presents two cases of nontyphoidal Salmonella that occurred at the authors' institution—an infected patient and a clinical laboratory worker who acquired the infection by handling this patient's specimens.

Very few studies from Pakistan have examined the profile of patients seen by psychiatrists in general hospital. The aim of this research is to describe the clinical and demographic characteristics of patients referred to the psychiatric unit of a general hospital over a one year period. Methods: This cross-sectional study was conducted at the Ayub Teaching Hospital, Abbottabad, from January 1st to December 31st 2012. All patients being referred to psychiatry were included in the study over one year period. The information was recorded on a structured questionnaire and analysed the data using SPSS-19.0. Results: Out of the 105 patients referred to the psychiatric unit, 74 (72.3%) were females. A total of 69 (68.5%) patients were married. More than half were uneducated and only number 4 (3%) patients had university qualification. Housewives made up 64.4% of the patient population followed by students (11%). Majority 55 (53%) had less than Rs. 5000/ monthly income. About 30% patients were shifted to psychiatry ward while, nearly one tenth were discharged. In 35% cases the psychiatrist was asked to help in the management, while in 50% cases only opinion was sought. Aggressive and threatening behaviour was source of concern in majority of patients for the primary team while 34% exhibited suicidal behaviour. Depression was most frequent diagnosis in 45 43% patients, followed by conversion disorder 19 (17%) and delirium 16 (14%). Conclusion: The rate of psychiatric referrals is dismal with only one third of the patients being transferred to the psychiatric ward. The major psychiatric diagnosis was depression. Patients with aggressive and threatening behaviour were more frequently referred. (author)

Adolescents with psychiatric conditions may be at risk for xerostomia. In this preliminary study, we estimated xerostomia prevalence in adolescents ages 9 to 17 years from an inpatient psychiatric clinic (N = 25) and examined whether: (1) gender and age were associated with xerostomia and (2) xerostomia was associated with self-reported cavities. We used a modified 11-item Xerostomia Index to identify xerostomia (no/yes) and asked if adolescents ever had or currently have cavities (no/yes). The mean age was 14 years (SD = 2.3) and 72% were male. Sixty percent reported xerostomia (SD = 50). There were no significant associations between xerostomia and gender (p = 0.99) or age (p = 0.66), or between xerostomia and past (p = 0.26) or current cavities (p = 0.11). Larger proportions of adolescents with xerostomia reported previous and current cavities. Sixty percent of adolescents from an inpatient psychiatric clinic reported having xerostomia, which may lead to increased caries risk over time. Additional research should examine the prevalence and consequences of xerostomia in high-risk adolescents. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

Agitation among psychiatric inpatients (particularly those diagnosed with schizophrenia or bipolar disorder) is common and, unless recognized early and managed effectively, can rapidly escalate to potentially dangerous behaviors, including physical violence. Inpatient aggression and violence have substantial adverse psychological and physical consequences for both patients and providers, and they are costly to the healthcare system. In contrast to the commonly held view that inpatient violence occurs without warning or can be predicted by "static" risk factors, such as patient demographics or clinical characteristics, research indicates that violence is usually preceded by observable behaviors, especially non-violent agitation. When agitation is recognized, staff should employ nonpharmacological de-escalation strategies and, if the behavior continues, offer pharmacological treatment to calm patients rapidly. Given the poor therapeutic efficacy and potential for adverse events associated with physical restraint and seclusion, and the potential adverse sequelae of involuntary drug treatment, these interventions should be considered last resorts. Pharmacological agents used to treat agitation include benzodiazepines and first- and second-generation antipsychotic drugs. Although no currently available agent is ideal, recommendations for selecting among them are provided. There remains an unmet need for a non-invasive and rapidly acting agent that effectively calms without excessively sedating patients, addresses the patient's underlying psychiatric symptoms, and is reasonably safe and tolerable. A treatment with these characteristics could substantially reduce the clinical and economic burden of agitation in the inpatient psychiatric setting.

To assess the present status of the clinical laboratory database management system, the difference between the Clinical Laboratory Information System and Clinical Laboratory System was explained in this study. Although three kinds of database management systems (DBMS) were shown including the relational model, tree model and network model, the relational model was found to be the best DBMS for the clinical laboratory database based on our experience and developments of some clinical laboratory expert systems. As a future clinical laboratory database management system, the IC card system connected to an automatic chemical analyzer was proposed for personal health data management and a microscope/video system was proposed for dynamic data management of leukocytes or bacteria.

The objective of this study was to test a model for analysing the possible benefits of clinical supervision. The model suggested a pathway from participation to effectiveness to benefits of clinical supervision, and included possible influences of individual and workplace factors. The study sample was 136 nursing staff members in permanent employment on nine general psychiatric wards and at four community mental health centres at a Danish psychiatric university hospital. Data were collected by means of a set of questionnaires. Participation in clinical supervision was associated with the effectiveness of clinical supervision, as measured by the Manchester Clinical Supervision Scale (MCSS). Furthermore, MCSS scores were associated with benefits, such as increased job satisfaction, vitality, rational coping and less stress, emotional exhaustion, and depersonalization. Multivariate analyses indicated that certain individual and workplace factors were related to subscales of the MCSS, as well as some of the benefits. The study supported the suggested model, but methodological limitations apply. © 2011 The Authors.

Routine laboratory reporting of estimated glomerular filtration rate (eGFR) may help clinicians detect kidney disease. The current national prevalence of eGFR reporting in clinical laboratories is unknown; thus, the extent of the situation of laboratories not routinely reporting eGFR with serum creatinine results is not quantified. Observational analysis. National Kidney Disease Education Program survey of clinical laboratories conducted in 2006 to 2007 by mail, web, and telephone follow-up. A national random sample, 6,350 clinical laboratories, drawn from the Federal Clinical Laboratory Improvement Amendments database and stratified by 6 major laboratory types/groupings. Laboratory reports serum creatinine results. Reporting eGFR values with serum creatinine results. Percentage of laboratories reporting eGFR along with reporting serum creatinine values, reporting protocol, eGFR formula used, and style of reporting cutoff values. Of laboratories reporting serum creatinine values, 38.4% report eGFR (physician offices, 25.8%; hospitals, 43.6%; independents, 38.9%; community clinics, 47.2%; health fair/insurance/public health, 45.5%; and others, 43.2%). Physician office laboratories have a reporting prevalence lower than other laboratory types (P laboratories reporting eGFR, 66.7% do so routinely with all adult serum creatinine determinations; 71.6% use the 4-variable Modification of Diet in Renal Disease Study equation; and 45.3% use the ">60 mL/min/1.73 m(2)" reporting convention. Independent laboratories are least likely to routinely report eGFR (50.6%; P laboratories across all strata are more likely to report eGFR (P laboratories, federal database did not have names of laboratory directors/managers (intended respondents), assumed accuracy of federal database for sample purposes. Routine eGFR reporting with serum creatinine values is not yet universal, and laboratories vary in their reporting practices.

The clinical presentation of hepatocellular carcinoma (HCC differs between patients in developing countries (African and Chinese populations from those in industrialized countries. In industrialized countries, HCC co-exists with symptomatic cirrhosis in 80% of cases and clinical manifestations are usually related to those of the underlying disease. On the other hand, patients from developing countries have HCC and cirrhosis in approximately 40% of cases. Underlying cirrhosis in many cases is not advanced and does not produce any symptoms or associated symptoms are masked by those of the tumor (right upper quadrant pain, mass in the upper abdomen, weight loss and weakness. In a subset of patients, there are no clinical manifestations as HCC may occur in the context of hepatitis B infection without cirrhosis.
In Western countries, nearly 35% percent of patients with HCC are asymptomatic. Some of the most common clinical manifestations include: abdominal pain (53-58% of patients, especially in epigastrium or right upper quadrant, abdominal mass (30%, weight loss, malaise, anorexia, cachexia, jaundice or fever.
Physical findings vary with the stage of disease. The patient may exhibit slight or moderate wasting when first seen. In patients with cirrhosis, typical stigmata of chronic liver disease may be present. In advanced stages of HCC the liver may be enlarged and there is significant tenderness. An arterial bruit may be heard over the liver
As the 2nd Joint Symposium of the Japanese Society of Laboratory Medicine and the Japanese Association of Laboratory Pathologists, the symposium on clinical test out-sourcing and branch laboratories was held at the 60th General Meeting of the Japanese Society of Laboratory Medicine on November 2nd, 2013 in Kobe. For the symposium, we conducted a questionnaire survey on the usage of clinical test out-sourcing and the introduction of branch laboratories to clinical laboratories of Japanese university hospitals, both private and public, between July 25th and August 20th, 2013. Seventy-two hospitals responded to the questionnaire survey, consisting of 41 public medical school hospitals and 31 private ones. According to the survey, the selection of each clinical test for out-sourcing was mainly determined by the capacities of hospital clinical laboratories and their equipment, as well as the profitability of each test. The main concerns of clinical laboratory members of university hospitals involved the continuity of measurement principles, traceability, and standardization of reference values for each test. They strongly requested the interchangeability and computerization of test data between laboratory testing companies. A branch laboratory was introduced to six hospitals, all of which were private medical college hospitals, out of 72 university hospitals, and eight of the other hospitals were open to its introduction. The merits and demerits of introducing a branch laboratory were also discussed. (Review).

To examine associations among substance use disorder (SUD) and measures of length of stay (LOS) and non-psychiatric medical comorbidity (MEDCO) in older-adult inpatients with serious mental illness (SMI), hypothesizing SUD would be related to worse clinical outcomes. A cross-sectional study analyzed medical records from 2010 to 2016 of 7258 inpatients with SMI ≥ age 50, obtained from a 274-bed psychiatric hospital. Descriptive analyses examined prevalence rates for SUD status (+/-), individual drug classes, and total number of SUDs (polysubstance use disorders). Regression models examined the influence of 2 independent variables of interest: (1) SUD status (+/-) and (2) type of SUD (ie, specific drug), controlling for demographic factors and additional (non-SUD) psychiatric disorders. Two dependent (outcome) variables were examined: LOS and MEDCO. The overall SUD rate was 26%; cocaine was the most common SUD (≈ 10%). SUD status and additional (non-SUD) psychiatric diagnoses were significantly associated with longer LOS (both P < 0.001). For individual SUDs, cocaine, marijuana, opiates, and alcohol were all significantly associated with LOS (all P < 0.01). SUD status, age, sex, admission status, and race were significantly associated with MEDCO (all P < 0.002). For individual SUDs, barbiturates, opiates, and alcohol were all significantly associated with MEDCO (P < 0.01). The prevalence of SUD in this sample underscores concerns related to treating older adults presenting providers with comorbid SUD and SMI. This combination may increase the burden and complexity of care, warranting further investigation into mechanisms and long-term consequences. Copyright © 2017 John Wiley & Sons, Ltd.
During the 20th century, at least until the 1980s, clinical laboratory practice had been rapidly expanded, mainly because of a significant advancement in medicine as a whole and also in laboratory technology. However, recent economic changes in health care environment worldwide have been influencing greatly future trends in clinical laboratory practice. Four major macroeconomic forces drive change in clinical laboratory practice as follows; (1) Increasing cost of health care, (2) Implications of an aging population, (3) Social change in the patient population, and (4) Explosion of new technologies. Obviously, the increasing cost of health care is the primary driver. Considering a rapid change in the health care environment, clearly there are two separate pathways to be considered with regard to future modes of delivering patient care services through the clinical laboratory: commercial independent laboratories and hospital laboratories. In most hospital laboratories, in addition to high-quality, accurate and precise laboratory data being delivered through automated informatics in a timely fashion, laboratory physicians and other laboratorians should be available 24 hours a day and 7 days a week. The primary purpose of this approach is to develop a system in which the physician can order the most efficient number of tests, which will provide the maximum amount of clinically relevant informations most rapidly and most accurately at the least cost to the patient. Laboratory physicians must play a key role particularly in hospital laboratories. Their most important roles include those of a professional supplier of laboratory results being useful for health care and clinically relevant, and that of a consultative role for primary care physicians and other co-medical staffs to make important medical decision, based on laboratory results obtained. Therefore, the Japan Society of Clinical Pathology started in 1990 in publishing a series of proposed guidelines for adequate

Patient-focused research, which uses clinical characteristics to predict outcomes, is a field in which information technology has been effectively integrated with practice. The present research used touch-screen technology to monitor the daily self-report measures of 1,308 consecutive inpatients and day patients participating in a 2-week cognitive-behavioral therapy group. Providing regular feedback was effective in reducing symptoms for patients at risk of poor outcomes (Newnham, Hooke, & Page, 2010b). The use of touch screens in psychiatric monitoring encourages a collaborative dialogue between patients and therapists and promotes engagement in the process of progress monitoring and treatment evaluation.

Only few studies have examined whether the efficacy of cognitive-behavioral therapy for childhood anxiety disorders as demonstrated in randomized controlled trials (RCTs) generalizes to clinical practice. This study examines the effectiveness of cognitive-behavioral therapy for juvenile anxiety disorders under routine care conditions in a university-based psychiatric outpatient clinic. 92 children and adolescents with parent-ratings regarding anxiety and comorbid symptoms and 61 children and adolescents with self-ratings regarding anxiety and comorbid symptoms were treated with cognitive-behavioral interventions. Pre/post mean comparisons, effect sizes, and the clinical significance of changes in symptoms were examined. The effect size for reduction of anxiety symptoms was .81 for children whose parents had completed the rating scale and .79 for children who had filled in a self-rating scale. Effect sizes for reduction of comorbid symptoms varied between .37 and .84 for parent ratings and between .21 and .62 for self-ratings. The percentage of children and adolescents who achieved clinically significant improvements in anxiety symptoms was 55.1 % according to the parent ratings and 65.7 % according to the children's self-ratings. More than 50 % of parents and children reported clinically significant improvements in comorbid symptoms. Significant reductions in both anxiety and comorbid symptoms were demonstrated over the course of cognitive-behavioral therapy of juvenile anxiety disorders in a university psychiatric outpatient clinic. The effect sizes for anxiety symptoms were found to be comparable to the effect sizes reported in RCTs. Similarly, clinically significant improvements were as frequent as the rates of remission of anxiety symptoms reported in RCTs.

Cultural Consultation is a clinical process that emerged from anthropological critiques of mental healthcare. It includes attention to therapeutic communication, research observations and research methods that capture cultural practices and narratives in mental healthcare. This essay describes the work of a Cultural Consultation Service (ToCCS) that improves service user outcomes by offering cultural consultation to mental health practitioners. The setting is a psychiatric service with complex and challenging work located in an ethnically diverse inner city urban area. Following a period of 18 months of cultural consultation, we gather the dominant narratives that emerged during our evaluation of our service. These narratives highlight how culture is conceptualized and acted upon in the day-to-day practices of individual health and social care professionals, specialist psychiatric teams and in care systems. The findings reveal common narratives and themes about culture, ethnicity, race and their perceived place and meaningfulness in clinical care. These narratives express underlying assumptions and covert rules for managing, and sometimes negating, dilemmas and difficulties when considering "culture" in the presentation and expression of mental distress. The narratives reveal an overall "culture of understanding cultural issues" and specific "cultures of care". These emerged as necessary foci of intervention to improve service user outcomes. Understanding the cultures of care showed that clinical and managerial over-structuring of care prioritises organisational proficiency, but it leads to inflexibility. Consequently, the care provided is less personalised and less accommodating of cultural issues, therefore, professionals are unable to see or consider cultural influences in recovery.

Little is known about the pattern of electroconvulsive therapy (ECT) use in the clinical population in China. This study examined the percentage of ECT use and its association with clinical characteristics and quality of life (QOL) in a psychiatric center in China that caters for a population of 20 million. A total sample of 1364 inpatients was consecutively recruited for the study. Demographic and clinical data including the use of ECT were collected. Psychopathology, activity of daily living and QOL were measured using standardized instruments. The percentage of ECT use was 52.1% in the whole sample; 53.4% in major depression, 57.8% in bipolar disorder, 57.0% in schizophrenia and 32.4% in other diagnoses. There was no significant difference between the ECT and non-ECT groups in any domain of QOL. Multivariate analyses revealed that ECT was independently associated with the diagnoses of major depression, bipolar disorder and schizophrenia, physical restraint, severe aggression, better activity of daily living skills, more frequent use of antipsychotics and less frequent use of benzodiazepines. The percentage of ECT use was much greater in a major psychiatric center in China than those reported from other parts of the world. Use of ECT had no influence on the short-term QOL. Further investigations are warranted to explore the reasons for the high percentage of ECT use. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique, which can be used to selectively disrupt patterns of neural activity that are associated with symptoms of mental illness. tDCS has been implemented in numerous therapeutic trials across a range of patient populations, with a rapidly increasing number of studies being published each year. This systematic review aimed to evaluate the efficacy of tDCS in the treatment of psychiatric disorders. Four electronic databases were searched from inception until December 2015 by two independent reviewers, and 66 eligible studies were identified. Depression was the most extensively researched condition, followed by schizophrenia and substance use disorders. Data on obsessive compulsive disorder, generalised anxiety disorder, and anorexia nervosa were also obtained. The quality of included studies was appraised using a standardised assessment framework, which yielded a median score corresponding to "weak" on the three-point scale. This improved to "moderate" when case reports/series were excluded from the analysis. Overall, data suggested that tDCS interventions comprising multiple sessions can ameliorate symptoms of several major psychiatric disorders, both acutely and in the long-term. Nevertheless, the tDCS field is still in its infancy, and several methodological and ethical issues must be addressed before clinical efficacy can truly be determined. Studies probing the mechanisms of action of tDCS and those facilitating the definition of optimised stimulation protocols are warranted. Furthermore, evidence from large-scale, multi-centre randomised controlled trials is required if the transition of this therapy from the laboratory to the clinic is to be considered.

Automation was introduced many years ago in several diagnostic disciplines such as chemistry, haematology and molecular biology. The first laboratory automation system for clinical bacteriology was released in 2006, and it rapidly proved its value by increasing productivity, allowing a continuous increase in sample volumes despite limited budgets and personnel shortages. Today, two major manufacturers, BD Kiestra and Copan, are commercializing partial or complete laboratory automation systems for bacteriology. The laboratory automation systems are rapidly evolving to provide improved hardware and software solutions to optimize laboratory efficiency. However, the complex parameters of the laboratory and automation systems must be considered to determine the best system for each given laboratory. We address several topics on laboratory automation that may help clinical bacteriologists to understand the particularities and operative modalities of the different systems. We present (a) a comparison of the engineering and technical features of the various elements composing the two different automated systems currently available, (b) the system workflows of partial and complete laboratory automation, which define the basis for laboratory reorganization required to optimize system efficiency, (c) the concept of digital imaging and telebacteriology, (d) the connectivity of laboratory automation to the laboratory information system, (e) the general advantages and disadvantages as well as the expected impacts provided by laboratory automation and (f) the laboratory data required to conduct a workflow assessment to determine the best configuration of an automated system for the laboratory activities and specificities.

This study extends three earlier investigations involving participants who completed their predoctoral clinical psychology internship at the William S. Hall Psychiatric Institute. Intern graduates (N = 37) evaluated how effectively their internship training prepared them for seven aspects of their current work as practicing psychologists. Participants also rated the relevancy of 24 different internship training experiences to their current work and how much these experiences contributed to their development as clinical psychologists. The present study, in conjunction with the three previous studies, covers most of the 40-year period since the inception of the internship program. Analysis of the current data indicates the internship has improved over time and was deemed an exceptional training experience by its graduates. Findings may be of particular interest to internship directors and faculty interested in improving their training program and those who plan to conduct a self-study to maintain their accreditation for clinical psychology internship.

To understand the potential causes of laboratory-acquired infections and to provide possible solutions that would protect laboratory personnel, samples from a viral laboratory were screened to determine the main sources of contamination with six subtypes of Rhinovirus. Rhinovirus contamination was found in the gloves, cuffs of protective wear, inner surface of biological safety cabinet (BSC) windows, and trash handles. Remarkably, high contamination was found on the inner walls of the centrifuge and the inner surface of centrifuge tube casing in the rotor. Spilling infectious medium on the surface of centrifuge tubes was found to contribute to contamination of centrifuge surfaces. Exposure to sodium hypochlorite containing no less than 0.2 g/L available chlorine decontaminated the surface of the centrifuge tubes from Rhinovirus after 2 min.

Fifty-five hospitals in the United States have been designated Ebola treatment centers (ETCs) by their state and local health authorities. Designated ETCs must have appropriate plans to manage a patient with confirmed Ebola virus disease (EVD) for the full duration of illness and must have these plans assessed through a CDC site visit conducted by an interdisciplinary team of subject matter experts. This study determined the clinical laboratory capabilities of these ETCs. ETCs were electronically surveyed on clinical laboratory characteristics. Survey responses were returned from 47 ETCs (85%). Forty-one (87%) of the ETCs planned to provide some laboratory support (e.g., point-of-care [POC] testing) within the room of the isolated patient. Forty-four (94%) ETCs indicated that their hospital would also provide clinical laboratory support for patient care. Twenty-two (50%) of these ETC clinical laboratories had biosafety level 3 (BSL-3) containment. Of all respondents, 34 (72%) were supported by their jurisdictional public health laboratory (PHL), all of which had available BSL-3 laboratories. Overall, 40 of 44 (91%) ETCs reported BSL-3 laboratory support via their clinical laboratory and/or PHL. This survey provided a snapshot of the laboratory support for designated U.S. ETCs. ETCs have approached high-level isolation critical care with laboratory support in close proximity to the patient room and by distributing laboratory support among laboratory resources. Experts might review safety considerations for these laboratory testing/diagnostic activities that are novel in the context of biocontainment care.

This paper discusses a knowledge management system for clinical laboratories. In the clinical laboratory of Toranomon Hospital, we receive about 20 questions relevant to laboratory tests per day from medical doctors or co-medical staff. These questions mostly involve the essence to appropriately accomplish laboratory tests. We have to answer them carefully and suitably because an incorrect answer may cause a medical accident. Up to now, no method has been in place to achieve a rapid response and standardized answers. For this reason, the laboratory staff have responded to various questions based on their individual knowledge. We began to develop a knowledge management system to promote the knowledge of staff working for the laboratory. This system is a type of knowledge base for assisting the work, such as inquiry management, laboratory consultation, process management, and clinical support. It consists of several functions: guiding laboratory test information, managing inquiries from medical staff, reporting results of patient consultation, distributing laboratory staffs notes, and recording guidelines for laboratory medicine. The laboratory test information guide has 2,000 records of medical test information registered in the database with flexible retrieval. The inquiry management tool provides a methos to record all questions, answer easily, and retrieve cases. It helps staff to respond appropriately in a short period of time. The consulting report system treats patients' claims regarding medical tests. The laboratory staffs notes enter a file management system so they can be accessed to aid in clinical support. Knowledge sharing using this function can achieve the transition from individual to organizational learning. Storing guidelines for laboratory medicine will support EBM. Finally, it is expected that this system will support intellectual activity concerning laboratory work and contribute to the practice of knowledge management for clinical work support.

To describe the diagnostic comorbidity and clinical correlates of posttraumatic stress disorder (PTSD) in adolescent psychiatric inpatients. Seventy-four adolescent inpatients were given a structured diagnostic interview, the revised version of the Diagnostic Interview for Children and Adolescents, and a battery of standard self-report measures to assess general trauma exposure, posttraumatic stress symptoms, suicidal behavior, dissociation, and depression. Ninety-three percent of subjects reported exposure to at least one traumatic event such as being a witness/victim of community violence, witnessing family violence, or being the victim of physical/sexual abuse. Thirty-two percent of subjects met diagnostic criteria for current PTSD, with sexual abuse cited as the most common traumatic stressor in 69% of PTSD cases. Girls were significantly more likely to develop PTSD than boys, although the total number of types of trauma did not differ by gender. Compared with psychiatric controls, male youngsters with PTSD were significantly more likely to have comorbid diagnoses of eating disorders, other anxiety disorders, and somatization disorder. Furthermore, male and female youngsters with PTSD were significantly more likely to have attempted suicide and report greater depressive and dissociative symptoms. In clinical populations of hospitalized adolescents exposed to multiple forms of trauma, PTSD is a common, but highly comorbid disorder. Specific multimodal assessments and treatments targeted to both PTSD and its comorbidity profile are warranted.
Full Text Available Abstract Background There is a dearth of studies regarding chemical restraint in routine clinical psychiatric practice. There may be wide variations between different settings and countries. Methods A retrospective study on chemical restraint was performed in the 11-bed psychiatric ward of the General Hospital of Arta, in northwestern Greece. All admissions over a 2-year-period (from March 2008 to March 2010 were examined. Results Chemical restraint was applied in 33 cases (10.5% of total admissions. From a total of 82 injections, 22 involved a benzodiazepine and/or levomepromazine, whereas 60 injections involved an antipsychotic agent, almost exclusively haloperidol (96.7% of cases, usually in combination with a benzodiazepine (61.7% of cases. In 36.4% of cases the patient was further subjected to restraint or seclusion. Conclusions In our unit, clinicians prefer the combined antipsychotic/benzodiazepine regimen for the management of patients' acute agitation and violent behaviour. Conventional antipsychotics are administrated almost exclusively and in a significant proportion of cases further coercive measures are applied. Studies on the practice of chemical restraint should be regularly performed in clinical settings.
Full Text Available Suicidal behavior (SB is a major, worldwide health concern. To date there is limited understanding of the associated motivational aspects which accompany this self-initiated conduct.To develop a method for identifying motivational features associated with SB by studying admitted psychiatric patients, and to examine their clinical relevance.By performing a factor analytic study using data obtained from a patient sample exhibiting high suicidality and a variety of SB methods, Motivations for SB Scale (MSBS was constructed to measure the features. Data included assessments of DSM-IV psychiatric and personality disorders, suicide intent, depressive symptomatology, overt aggression, recent life events (RLEs and methods of SB, collated from structured interviews. Association of identified features with clinical variables was examined by correlation analyses and MANCOVA.Factor analyses elicited a 4-factor solution composed of Interpersonal-testing (IT, Interpersonal-change (IC, Self-renunciation (SR and Self-sustenance (SS. These factors were classified according to two distinctions, namely interpersonal vs. intra-personal directedness, and the level of assumed influence by SB or the relationship to prevailing emotions. Analyses revealed meaningful links between patient features and clinical variables. Interpersonal-motivations (IT and IC were associated with overt aggression, low suicidality and RLE discord or conflict, while SR was associated with depression, high suicidality and RLE separation or death. Borderline personality disorder showed association with IC and SS. When self-strangulation was set as a reference SB method, self-cutting and overdose-taking were linked to IT and SS, respectively.The factors extracted in this study largely corresponded to factors from previous studies, implying that they may be useful in a wider clinical context. The association of these features with SB-related factors suggests that they constitute an integral part
International Organization for Standardization (ISO) have published two international standards (IS) to be used for accreditation of clinical laboratories; ISO/IEC 17025:1999 and ISO 15189:2003. Any laboratory accreditation body must satisfy the requirements stated in ISO/IEC Guide 58. In order to maintain the quality of the laboratory accreditation bodies worldwide, the International Laboratory Accreditation Cooperation (ILAC) has established the mutual recognition arrangement (MRA). In Japan, the International Accreditation Japan (IAJapan) and the Japan Accreditation Board for Conformity Assessment (JAB) are the members of the ILAC/MRA group. In 2003, the Japanese Committee for Clinical Laboratory Standards (JCCLS) and the JAB have established the Development Committee of Clinical Laboratory Accreditation Program (CLAP), in order to establish the CLAP, probably starting in 2005.

The purpose of this qualitative study was to test a teaching-learning strategy to help nursing students decrease stress and anxiety that may be brought about by the psychiatric mental health clinical experience. Undergraduate nursing students are known to experience affective stress prior to their first psychiatric mental health clinical practicum. A stressful learning environment can affect the success of the student's clinical performance. Thirty nursing students participated in this study. A structured preclinical workshop combined with self-reflection provided insight into students' perceptions of the psychiatric mental health clinical experience. Overall, students reported that participating in the teaching-learning strategy and self-reflection helped mitigate Combining structured learning with self-reflection is a useful tool for helping nursing students increase self-awareness and ease anxiety that may interfere with learning.

Healthcare is a significant contributor to environmental impact but this has received little attention. The typical laboratory uses far more energy and water per unit area than the typical office building. There is a need to sensitise laboratories to the importance of adopting good environmental practices. Since this comes at an initial cost, it is vital to obtain senior management support. Convincing management of the various tangible and intangible benefits that can accrue in the long run should help achieve this support. Many good environmental practices do not have a cost but will require a change in the culture and mind-set of the organisation. Continuing education and training are important keys to successful implementation of good practices. There is a need to undertake a rigorous cost-benefit analysis of every change that is introduced in going green. The adoption of good practices can eventually lead to ISO certification if this is desired. This paper provides suggestions that will allow a laboratory to start going green. It will allow the industry to enhance its corporate citizenship whilst improving its competitive advantage for long-term.

The development of students' critical thinking abilities is one of the greatest challenges facing contemporary nursing educators. Nursing educators should know about what kind of contents or situations need critical thinking. The research was undertaken to identify the critical thinking contexts that nursing students confront in psychiatric clinical practices. Students were asked to document their everyday experience. The narratives were analysed and interpreted from the philosophical notion of hermeneutics. Four themes emerged as critical thinking contexts: anxiety, conflict, hyper-awareness, dilemmas. Writing narratives appear to provide opportunities for reflection in addition to facilitating critical thinking and communicative skills in students. Also, for the instructor, students' clinical narratives could provide insight to understand how students are thinking and to share student's personal difficulties.
One important trend in the laboratory profession and quality management is the global convergence of laboratory operations. The goal of an accredited medical laboratory is to continue "offering useful laboratory service for diagnosis and treatment of the patients and also aid to the health of the nation". An accredited clinical laboratory is managed by a quality control system, it is competent technically and the laboratory service meets the needs of all its patients and physicians by taking the responsibility of all the medical tests and therapies. For this purpose, ISO 15189 international standard has been prepared by 2003. ISO 15189 standard is originated from the arrangement of ISO 17025 and ISO 9001:2000 standards. Many countries such as England, Germany, France, Canada and Australia have preferred ISO 15189 as their own laboratory accreditation programme, meeting all the requirements of their medical laboratories. The accreditation performance of a clinical microbiology laboratory is mainly based on five essential points; preanalytical, analytical, postanalytical, quality control programmes (internal, external, interlaboratory) and audits (internal, external). In this review article, general concepts on ISO 15189 accreditation standards for the clinical microbiology laboratories have been summarized and the status of a private laboratory (Acibadem LabMed, Istanbul) in Turkey has been discussed.

Patient dropout from treatment can lead to a deterioration in clinical condition, thereby increasing the need for more intensive therapy that incurs substantial social and economic losses. The aim of this study was to identify factors related to psychiatric patient dropout at a university outpatient clinic in Japan. We retrospectively examined the medical charts of new psychiatric patients who were diagnosed with either a mood disorder (International Classification of Diseases, 10th revision, code: F3) or an anxiety disorder (F4) in the outpatient clinic at Kyoto Prefectural University of Medicine Hospital in Kyoto, Japan, between April 2010 and March 2013. The baseline characteristics of the patients (age, sex, Global Assessment of Functioning score, Clinical Global Impression-Severity of Illness score, education, occupation, marital status, duration of treatment, and prior treatment history), treating psychiatrist experience in years, and sex concordance between the patients and their treating psychiatrists were analyzed using Cox regression models. From among 1,626 eligible new patients during the study period, 532 patients were enrolled in the study (F3: n=176; F4: n=356). The dropout rate was 35.7%, which was similar to that of previous studies. Higher educational level, being married, and lower Global Assessment of Functioning scores were associated with a lower dropout rate. Although psychiatrist experience was not significantly associated with patient dropout in the multivariate analysis, patients treated by less experienced psychiatrists had a higher hazard ratio for dropout (1.31; 95% confidence interval: 0.94-1.85). In order to reduce the dropout rate, special focus should be placed on patients with the factors identified in this study, and young psychiatrists should undergo further education to foster adherence.

This review summarizes evidence of dysregulated reward circuitry function in a range of neurodevelopmental and psychiatric disorders and genetic syndromes. First, the contribution of identifying a core mechanistic process across disparate disorders to disease classification is discussed, followed by a review of the neurobiology of reward circuitry. We next consider preclinical animal models and clinical evidence of reward-pathway dysfunction in a range of disorders, including psychiatric disorders (i.e., substance-use disorders, affective disorders, eating disorders, and obsessive compulsive disorders), neurodevelopmental disorders (i.e., schizophrenia, attention-deficit/hyperactivity disorder, autism spectrum disorders, Tourette's syndrome, conduct disorder/oppositional defiant disorder), and genetic syndromes (i.e., Fragile X syndrome, Prader-Willi syndrome, Williams syndrome, Angelman syndrome, and Rett syndrome). We also provide brief overviews of effective psychopharmacologic agents that have an effect on the dopamine system in these disorders. This review concludes with methodological considerations for future research designed to more clearly probe reward-circuitry dysfunction, with the ultimate goal of improved intervention strategies.

This essay describes the work of a Cultural Consultation Service (ToCCS that improves service user outcomes by offering cultural consultation to mental health practitioners. The setting is a psychiatric service with complex and challenging work located in an ethnically diverse inner city urban area. Following a period of 18 months of cultural consultation, we gather the dominant narratives that emerged during our evaluation of our service. Results These narratives highlight how culture is conceptualized and acted upon in the day-to-day practices of individual health and social care professionals, specialist psychiatric teams and in care systems. The findings reveal common narratives and themes about culture, ethnicity, race and their perceived place and meaningfulness in clinical care. These narratives express underlying assumptions and covert rules for managing, and sometimes negating, dilemmas and difficulties when considering “culture” in the presentation and expression of mental distress. The narratives reveal an overall “culture of understanding cultural issues” and specific “cultures of care”. These emerged as necessary foci of intervention to improve service user outcomes. Conclusion Understanding the cultures of care showed that clinical and managerial over-structuring of care prioritises organisational proficiency, but it leads to inflexibility. Consequently, the care provided is less personalised and less accommodating of cultural issues, therefore, professionals are unable to see or consider cultural influences in recovery.

To describe the characteristics of people attending mental health clinics at shelters for the homeless in inner city Sydney. Retrospective review of medical records of homeless hostel clinic attenders. Mental health clinics located in three inner city homeless hostels. Consecutive series of clinic attenders, 21 July 2008 - 31 December 2016. Demographic characteristics; social, medical and mental health histories of homeless people. 2388 individual patients were seen at the clinics during the 8.5-year study period. Their mean age was 42 years (standard deviation, 13 years), 93% were men, and 56% were receiving disability support pensions. 59% of attenders had been homeless for more than a year, and 34% of all attenders reported sleeping in the open. The most common diagnoses were substance use disorder (66%), psychotic illness (51%), acquired brain injury (14%), and intellectual disability (5%). Most patients had more than one diagnosis. Early life and recent trauma was reported by 42% of patients. Pathways to homelessness included release from prison (28% of the homeless), discharge from a psychiatric hospital (21%), loss of public housing tenancy (21%), and inability to pay rent because of problem gambling. The high rates of substance use and mental disorder among homeless people in inner Sydney confirms the need for increased access to treatment for these conditions in this setting. Homelessness among those with mental illness might be reduced by developing alternative housing models, and supporting people with multiple problems to retain tenancy.

There is no specific toxicological screening of clinical laboratory parameters in clinical toxicology when it comes to acute exogenous poisoning. To determine routine clinical laboratory parameters and indicators for assessment of vital functions in patients with acute intoxications. One hundred and fifty-three patients were included in the present study. They were hospitalized in the Department of Clinical Toxicology at St. George University Hospital, Plovdiv for cerebral toxicity inducing medication (n = 45), alcohol (n = 40), heroin abuse (n = 33). The controls were 35. The laboratory tests were conducted in compliance with the standards of the clinical laboratory. We used the following statistical analyses: analysis of variance (the ucriterion of normal distribution, the Student's t-test, dispersion analysis based on ANOVA) and non-parametric analysis. Based on the routine hematological parameters with statistically significant changes in three groups of poisoning are: red blood cells, hematocrit, hemoglobin (except alcohol intoxication) and leukocytes. We found statistically significant changes in serum total protein, sodium and bilirubin. The highest statistical significance is the increased activity of AST and ALT. We present a model for selection of clinical laboratory tests for severe acute poisoning with modern equipment under standardized conditions. The results of the study suggest that the clinical laboratory constellation we used can be used as a mandatory element in the diagnosis of moderate and severe intoxication with the mentioned toxic substances.

The CAP (College of American Pathologists) was established in 1962 and, at present, CAP-accredited laboratories include about 6000 institutions all over the world, mainly in the U.S. The essential purpose of CAP accreditation is high quality reservation and improvement of clinical laboratory services for patient care, and is based on seven points, listed below. (1) Establishment of a laboratory management program and laboratory techniques to assure accuracy and improve overall quality of laboratory services. (2) Maintenance and improvement of accuracy objectively by centering on a CAP survey. (3) Thoroughness in safety and health administration. (4) Reservation of the performance of laboratory services by personnel and proficiency management. (5) Provision of appropriate information to physicians, and contribution to improved quality of patient care by close communication with physicians (improvement in patient care). (6) Reduction of running costs and personnel costs based on evidence by employing the above-mentioned criteria. (7) Reduction of laboratory error. In the future, accreditation and/or certification by organizations such as CAP, ISO, etc., may become a requirement for providing any clinical laboratory services in Japan. Taking the essence of the CAP and the characteristics of the new international standard, ISO151589, into consideration, it is important to choose the best suited accreditation and/or certification depending of the purpose of clinical laboratory.

To evaluate clinic based and laboratory tests of otolith function for their sensitivity and specificity in demarcating unilateral compensated complete vestibular deficit from normal. Prospective cross-sectional study. Tertiary care hospital vestibular physiology laboratory. Control group-30 healthy adults, 20-45 years age; Case group-15 subjects post vestibular shwannoma excision or post-labyrinthectomy with compensated unilateral complete audio-vestibular loss. Otolith function evaluation by precise clinical testing (head tilt test-HTT; subjective visual vertical-SVV) and laboratory testing (headroll-eye counterroll-HR-ECR; vesibular evoked myogenic potentials-cVEMP). Sensitivity and specificity of clinical and laboratory tests in differentiating case and control subjects. Measurable test results were universally obtained with clinical otolith tests (SVV; HTT) but not with laboratory tests. The HR-ECR test did not indicate any definitive wave forms in 10% controls and 26% cases. cVEMP responses were absent in 10% controls.HTT test with normative cutoff at 2 degrees deviations from vertical noted as 93.33% sensitive and 100% specific. SVV test with normative cutoff at 1.3 degrees noted as 100% sensitive and 100% specific. Laboratory tests demonstrated poorer specificities owing primarily to significant unresponsiveness in normal controls. Clinical otolith function tests, if conducted with precision, demonstrate greater ability than laboratory testing in discriminating normal controls from cases with unilateral complete compensated vestibular dysfunction.

The Global Assessment of Functioning (GAF) is the standard method and an essential tool for representing a clinician's judgment of a patient's overall level of psychological, social and occupational functioning. As such, it is probably the single most widely used method for assessing impairment among the patients with psychiatric illnesses. To assess the effects of one-hour training on application of the GAF by Psychiatric Clinical Officers' in a Ugandan setting. Five Psychiatrists and five Psychiatric Clinical Officers (PCOs) or Assistant Medical Officers who hold a 2 year diploma in Clinical Psychiatry were randomly selected to independently rate a video-recorded psychiatric interview according to the DSM IV-TR. The PCOs were then offered a one-hour training on how to rate the GAF scale and asked to rate the video case interview again. All ratings were assigned on the basis of past one year, at admission and current functioning. Interclass correlations (ICC) were computed using two-way mixed models. The ICC between the psychiatrists and the PCOs before training in the past one year, at admission and current functioning were +0.48, +0.51 and +0.59 respectively. After training, the ICC coefficients were +0.60, +0.82 and +0.83. Brief training given to PCOs improved the applications of their ratings of GAF scale to acceptable levels. There is need for formal training to this cadre of psychiatric practitioners in the use of the GAF.

Imported parasitosis represents an increasingly frequent diagnostic challenge for microbiology laboratories. A surge in immigration and international travel has led to a rise in the number of imported cases of parasitosis, and this trend is expected to continue in the future. The present article addresses this challenge by reviewing recommended diagnostic approaches and tests. Currently, microscopy is always recommended when analysing blood samples for parasites. If malaria is suspected, rapid antigen testing (including at least HRP2 antigen) should also be performed. The work-up for suspected leishmaniasis should include serology, culture, and in selected cases detection of antigen in urine. In suspected Chagas disease, two different serological tests should be performed. PCR for blood protozoa is highly sensitive, although it cannot be used to rule out Chagas disease, since this condition may be present without parasitemia. Accurate diagnosis of intestinal amebiasis usually requires PCR or antigen detection tests. In helminthiasis, traditional microscopy may need to be complemented with other tests, such as agar plate culture for strongyloidiasis, Og4C3 antigen detection for bancroftian filariasis, and antibody detection test for filariasis and schistosomiasis.

Full Text Available Abstract Background Several countries have established or are planning acute psychiatric in-patient services that accept around-the-clock emergency admission of adolescents. Our aim was to investigate the characteristics and clinical outcomes of a cohort of patients at four Norwegian units. Methods We used a prospective pre-post observational design. Four units implemented a clinician-rated outcome measure, the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA, which measures mental health problems and their severity. We collected also data about the diagnoses, suicidal problems, family situations, and the involvement of the Child Protection Service. Predictions of outcome (change in HoNOSCA total score were analysed with a regression model. Results The sample comprised 192 adolescents admitted during one year (response rate 87%. Mean age was 15.7 years (range 10-18 and 70% were girls. Fifty-eight per cent had suicidal problems at intake and the mean intake HoNOSCA total score was 18.5 (SD 6.4. The largest groups of main diagnostic conditions were affective (28% and externalizing (26% disorders. Diagnoses and other patient characteristics at intake did not differ between units. Clinical psychiatric disorders and developmental disorders were associated with severity (on HoNOSCA at intake but not with outcome. Of adolescents ≥ 16 years, 33% were compulsorily admitted. Median length of stay was 8.5 days and 75% of patients stayed less than a month. Compulsory admissions and length of stay varied between units. Mean change (improvement in the HoNOSCA total score was 5.1 (SD 6.2, with considerable variation between units. Mean discharge score was close to the often-reported outpatient level, and self-injury and emotional symptoms were the most reduced symptoms during the stay. In a regression model, unit, high HoNOSCA total score at intake, or involvement of the Child Protection Service predicted improvement during admission

As in the usual care of patients, paraclinical investigations have today only a very modest role in clinical trials in psychiatry, mainly to complete the pre-therapeutical assessments prior to inclusion of subjects or to monitor treatment tolerance. Yet, the accumulation of data in neurosciences suggests the next emergence of biomarkers, whose interest is that they are closely associated to the biological disturbances underlying psychiatric illnesses, and that they are accessible by means of technological tools such as imaging devices. These tools allow to explore the effects on brain of psychotropic medications, such as antidepressants, antipsychotics, or mood stabilizers, in relation to their therapeutic action. The obtained results allow to consider the use of such biomarkers in clinical trials in addition to more conventional approaches. In particular, they could be used as targets to measure brain response to treatment in association with clinical response, to predict a therapeutic response from the neurofunctional characteristics of patients, or to establish the safety profile of drugs on the nervous system. The use of such biomarkers in clinical trials would help to better define the explored populations and their characteristics, as well as the variables to assess, and to better measure the impact of the treatments and their potential harmful effects on the nervous system. © L’Encéphale, Paris, 2016.

Laboratory capacity in the developing world frequently lacks quality management systems (QMS) such as good clinical laboratory practices, proper safety precautions, and adequate facilities; impacting the ability to conduct biomedical research where it is needed most. As the regulatory climate changes globally, higher quality laboratory support is needed to protect study volunteers and to accurately assess biological parameters. The University of Bamako and its partners have undertaken a comprehensive QMS plan to improve quality and productivity using the Clinical and Laboratory Standards Institute standards and guidelines. The clinical laboratory passed the College of American Pathologists inspection in April 2010, and received full accreditation in June 2010. Our efforts to implement high-quality standards have been valuable for evaluating safety and immunogenicity of malaria vaccine candidates in Mali. Other disease-specific research groups in resource-limited settings may benefit by incorporating similar training initiatives, QMS methods, and continual improvement practices to ensure best practices.

Full Text Available Antiphospholipid antibodies (aPL represent a heterogeneous group of antibodies that recognize various antigenic targets including beta2 glycoprotein I (β2GPI, prothrombin (PT, activated protein C, tissue plasminogen activator, plasmin and annexin A2. The most commonly used tests to detect aPL are: lupus anticoagulant (LAC, a functional coagulation assay, anticardiolipin antibody (aCL and anti-β2GPI antibody (anti-β2GPI, which are enzyme-linked immunoassay (ELISA. Clinically aPL are associated with thrombosis and/or with pregnancy morbidity. Apparently aPL alone are unable to induce thrombotic manifestations, but they increase the risk of vascular events that can occur in the presence of another thrombophilic condition; on the other hand obstetrical manifestations were shown to be associated not only to thrombosis but mainly to a direct antibody effect on the trophoblast.

Advances in neuromodulation and an improved understanding of the anatomy and circuitry of psychopathology have led to a resurgence of interest in surgery for psychiatric disease. Clinical trials exploring deep brain stimulation (DBS), a focally targeted, adjustable and reversible form of neurosurgery, are being developed to address the use of this technology in highly selected patient populations. Psychiatric patients deemed eligible for surgical intervention, such as DBS, typically meet stringent inclusion criteria, including demonstrated severity, chronicity and a failure of conventional therapy. Although a humanitarian device exemption by the US Food and Drug Administration exists for its use in obsessive-compulsive disorder, DBS remains a largely experimental treatment in the psychiatric context, with its use currently limited to clinical trials and investigative studies. The combination of a patient population at the limits of conventional therapy and a novel technology in a new indication poses interesting challenges to the informed consent process as it relates to clinical trial enrollment. These challenges can be divided into those that relate to the patient, their disease and the technology, with each illustrating how traditional conceptualisations of research consent may be inadequate in the surgical psychiatry context. With specific reference to risk analysis, patient autonomy, voluntariness and the duty of the clinician-researcher, this paper will discuss the unique challenges that clinical trials of surgery for refractory psychiatric disease present to the consent process. Recommendations are also made for an ethical approach to clinical trial consent acquisition in this unique patient population.

Full Text Available The paper describes the results of research aimed at assessing the current conditions related to clinical laboratory technologist professional development. A descriptive cross study covering the period between November 2013 and January 2014 is presented. Several techniques for identifying and hierarchically arranging professional developmental related problems were used to study a sample at the Faculty of Health Technology of the Medical University “Carlos Juan Finlay”. The study involved heads of teaching departments and methodologists of health care technology specialties; moreover a survey and a content test were given graduate clinical laboratory technicians. The authors reached at the conclusion that clinical laboratory technologist professional development is limited and usually underestimate the necessities and interests of these graduates. Likewise, a lack of systematization and integration of the biomedical basic sciences contents and the laboratory diagnosis is noticeable.

Infectious diseases are still a cause of high mortality and morbidity rates. Current microbiological diagnostic methods are based on culture and phenotypic identification of isolated microorganisms, which can be obtained in about 24-48 h. Given that the microbiological identification is of major importance for patient management, new diagnostic methods are needed in order to detect and identify microorganisms in a timely and accurate manner. Over the last few years, several molecular techniques based on the amplification of microbial nucleic acids have been developed with the aim of reducing the time needed for the identification of the microorganisms involved in different infectious processes. On the other hand, mass spectrometry has emerged as a rapid and consistent alternative to conventional methods for microorganism identification. This review describes the most widely used mass spectrometry technologies -matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) and electrospray ionization time-of-flight (ESI-TOF)-, both for protein and nucleic acid analysis, as well as the commercial platforms available. Related publications of most interest in clinical microbiology are also reviewed. Copyright © 2011 Elsevier España, S.L. All rights reserved.
The Applied Pharmaceutical Software Meeting is held annually. It is sponsored by The Boston Society, a not-for-profit organization that coordinates a series of meetings within the global pharmaceutical industry. The meeting generally focuses on laboratory applications, but in recent years has expanded to include some software applications for clinical trials. The 2011 meeting emphasized the global laboratory environment. Global clinical trials generate massive amounts of data in many locations that must be centralized and processed for efficient analysis. Thus, the meeting had a strong focus on establishing networks and systems for dealing with the computer infrastructure to support such environments. In addition to the globally installed laboratory information management system, electronic laboratory notebook and other traditional laboratory applications, cloud computing is quickly becoming the answer to provide efficient, inexpensive options for managing the large volumes of data and computing power, and thus it served as a central theme for the meeting.

To assess the concordance between patients' preferred role in clinical decision-making and the role they usually experience in their psychiatric consultations and to analyze the influence of socio-demographic, clinical and personality characteristics on patients' preferences. 677 consecutive psychiatric outpatients were invited to participate in a cross-sectional survey and 507 accepted. Patients completed Control Preference Scale twice consecutively before consultation, one for their preferences of participation and another for the style they usually experienced until then, and locus of control and self-efficacy scales. Sixty-three percent of psychiatric outpatients preferred a collaborative role in decision-making, 35% preferred a passive role and only a 2% an active one. A low concordance for preferred and experienced participation in medical decision-making was registered, with more than a half of patients wanting a more active role than they actually had. Age and doctors' health locus of control orientation were found to be the best correlates for participation preferences, while age and gender were for experienced. Psychiatric diagnoses registered significant differences in patients' preferences of participation but no concerning experiences. The limited concordance between preferred and experienced roles in psychiatric patients is indicative that clinicians need to raise their sensitivity regarding patient's participation. The assessment of patient's attribution style should be useful for psychiatrist to set objectives and priority in the communication with their patients. Copyright © 2014 Elsevier Ireland Ltd.

To perform SWOT (strengths, weaknesses, opportunities, and threats) analysis of a clinical laboratory as an economic model that may be used to improve business performance of laboratories by removing weaknesses, minimizing threats, and using external opportunities and internal strengths. Impact of possible threats to and weaknesses of the Clinical Laboratory at Našice General County Hospital business performance and use of strengths and opportunities to improve operating profit were simulated using models created on the basis of SWOT analysis results. The operating profit as a measure of profitability of the clinical laboratory was defined as total revenue minus total expenses and presented using a profit and loss account. Changes in the input parameters in the profit and loss account for 2008 were determined using opportunities and potential threats, and economic sensitivity analysis was made by using changes in the key parameters. The profit and loss account and economic sensitivity analysis were tools for quantifying the impact of changes in the revenues and expenses on the business operations of clinical laboratory. Results of simulation models showed that operational profit of €470 723 in 2008 could be reduced to only €21 542 if all possible threats became a reality and current weaknesses remained the same. Also, operational gain could be increased to €535 804 if laboratory strengths and opportunities were utilized. If both the opportunities and threats became a reality, the operational profit would decrease by €384 465. The operational profit of the clinical laboratory could be significantly reduced if all threats became a reality and the current weaknesses remained the same. The operational profit could be increased by utilizing strengths and opportunities as much as possible. This type of modeling may be used to monitor business operations of any clinical laboratory and improve its financial situation by implementing changes in the next fiscal

With the popularity of accelerated pre-licensure nursing programmes and the growth in nursing student enrolments, traditional clinical education continues to be a challenge to deliver. Nursing faculty members are required to develop and implement educational innovations that achieve effective learning outcomes, while using fewer resources. The purpose of this qualitative study was to explore the effectiveness of a constructivism-based learning project to achieve specific learning outcomes and to supplement approximately 30 clinical hours in a psychiatric-mental health nursing course. Students participated in a 10-week, multistage project that examined life histories, treatment resources, and evidence-based practice, as applied to a single individual with a mental illness. Students reported increased understanding of mental health and illness, developed personal relevance associated with the knowledge gained, and learned to problem solve with regard to nursing care of individuals diagnosed with mental illness. For many students, there also appeared to be a reduction in stigmatized attitudes towards mental illness. Constructivism-based learning is a promising alternative to supplement clinical hours, while effectively achieving learning outcomes. Future research is needed to further validate the use of this method for the learning of course content, as well as the reduction of stigma. © 2011 The Author.

Full Text Available Jon O Ebbert, Kirk D Wyatt, Ali Zirakzadeh, Michael V Burke, JT HaysMayo Clinic College of Medicine, Mayo Clinic, Rochester, MN, USAAbstract: Chronic obstructive pulmonary disease (COPD is a costly and deadly disease afflicting an estimated 210 million people and accounting for 5% of all global deaths. Exposure to cigarette smoke is the greatest risk factor for COPD in the developed world. Smoking cessation improves respiratory symptoms and lung function and reduces mortality among patients with COPD. Cigarette smokers with COPD and other co-morbid conditions such as cardiovascular disease and psychiatric illnesses should receive comprehensive tobacco treatment interventions incorporating efficacious pharmacotherapies. Varenicline, an α4β2 nicotinic acetylcholine receptor partial agonist, is the newest and most effective drug currently available to promote smoking cessation. In conjunction with behavioral interventions and clinical monitoring for potential side effects, varenicline offers great hope for reducing smoking-attributable death and disability.Keywords: smoking cessation, chronic obstructive pulmonary disease, varenicline

To explore transsexual patients' perceptions of communication with psychiatrists in a Gender Identity Clinic and advance understanding of patient centered communication (PCC) in psychiatric, 'gatekeeping' settings. 21 qualitative interviews with a convenience sample of clinic patients. Interviews were coded at a semantic level and subject to an inductive thematic analysis. Patients' perceptions clustered into three themes: (1) aspects of communication that patients described liking; (2) aspects of communication that patients described disliking; and (3) aspects of communication that patients deemed challenging but necessary or useful. Patients described liking or disliking aspects of communication that reflect existing understandings of PCC. However, a striking feature of their accounts was how they were able to rationalize and reflect pragmatically on their negative communication experiences, welcoming doctors' challenges as an opportunity to consider their life-changing decision to transition from their natal gender. In certain clinical settings, current operationalizations of PCC may not apply. Patients' perceptions of communication may be enhanced if an analysis of their experiences formed part of the professional training of doctors, who could be invited to consider the functional specificity of communication across settings and the consequences (both immediate and post hoc) of their communication practices.

It is meaningful to discuss the "present and future of laboratories" for the development of laboratories and education of medical technologists. Laboratory staff must be able to perform urgent high-quality tests and take part in so-called team-based medicine and should be proud of devising systems that efficiently provide laboratory data for all medical staff. On the other hand, there may be staff with a poor sense of professionalism who work no more than is expected and too readily ask firms and commercial laboratories to solve problems. Overwork caused by providing team-based medicine and a decrease in numbers of clinical chemists are concerns. The following are hoped for in the future. Firstly, laboratory staff will become conscious of their own high-level abilities and expand their areas of work, for example, bioscience, proteomics, and reproductive medicine. Secondly, a consultation system for medical staff and patients will be established. Thirdly, clinical research will be advanced, such as investigating unknown pathophysiologies using laboratory data and samples, and developing new methods of measurement. Lastly, it is of overriding importance that staff of laboratory and educational facilities will cooperate with each other to train the next generation. In conclusion, each laboratory should be appreciated, attractive, positive regarding its contribution to society, and show individuality.
Full Text Available AIM: Dengue is a major health problem in many parts of India and Gulbarga (North Karnataka was previously not a known endemic area f or dengue. Infection with dengue virus can cause a spectrum of three clinical syndromes , classic dengue fever (DF , dengue hemorrhagic fever (DHF and dengue shock syndrome (DSS. The present study was undertaken to determine the disease profile of dengue virus infection in hospitalized patients. METHODS AND MATERIAL: One hundred patients admitted in Basaveshwar Teaching and General hospital with fever more than 38.5 degree Celsius and IgM dengue positive were selected. They were followed from the onset of fever to twelve days or till they are recovered according to WHO discharge criteria whichever is earlier. They underwent relevant investigations to identify specific organ dysfunction and categorize them into the spectrum of Dengue fever in accordance to W HO criteria . RESULTS: Out of 100 cases in this study 70 cases belongs to DF , 23 cases to DHF and 7 cases to DSS based on WHO criteria. All the cases had fever (100%. Other common symptoms noted were myalgia (61% , joint pain (54% , headache (66% , vomitin g (55% , pain abdomen (48% , rash (41% , hepatomegaly (20% , bleeding (21% and shock (8%. Hess test was positive in 24% patients. Low platelet count of less than 100 , 000/cu mm according to WHO criteria was present in 73% patients. Deranged liver functio n test and renal parameters were seen in 26 and 8 patients respectively . Mortality documented was 7 patients due to delayed presentation.

The aim of this study was to identify factors related to psychiatric patient dropout at a university outpatient clinic in Japan.Methods: We retrospectively examined the medical charts of new psychiatric patients who were diagnosed with either a mood disorder (International Classification of Diseases, 10th revision, code: F3 or an anxiety disorder (F4 in the outpatient clinic at Kyoto Prefectural University of Medicine Hospital in Kyoto, Japan, between April 2010 and March 2013. The baseline characteristics of the patients (age, sex, Global Assessment of Functioning score, Clinical Global Impression–Severity of Illness score, education, occupation, marital status, duration of treatment, and prior treatment history, treating psychiatrist experience in years, and sex concordance between the patients and their treating psychiatrists were analyzed using Cox regression models.Results: From among 1,626 eligible new patients during the study period, 532 patients were enrolled in the study (F3: n=176; F4: n=356. The dropout rate was 35.7%, which was similar to that of previous studies. Higher educational level, being married, and lower Global Assessment of Functioning scores were associated with a lower dropout rate. Although psychiatrist experience was not significantly associated with patient dropout in the multivariate analysis, patients treated by less experienced psychiatrists had a higher hazard ratio for dropout (1.31; 95% confidence interval: 0.94–1.85.Conclusion: In order to reduce the dropout rate, special focus should be placed on

Melioidosis is a potentially fatal infection caused by the bacterium Burkholderia pseudomallei Clinical diagnosis of melioidosis can be challenging since there is no pathognomonic clinical syndrome, and the organism is often misidentified by methods used routinely in clinical laboratories. Although the disease is more prevalent in Thailand and northern Australia, sporadic cases may be encountered in areas where it is not endemic, including the United States. Since the organism is considered a tier 1 select agent according to the Centers for Disease Control and Prevention and the U.S. Department of Agriculture Animal and Plant Health Inspection Service, clinical laboratories must be proficient at rapidly recognizing isolates suspicious for B. pseudomallei, be able to safely perform necessary rule-out tests, and to refer suspect isolates to Laboratory Response Network reference laboratories. In this minireview, we report a case of melioidosis encountered at our institution and discuss the laboratory challenges encountered when dealing with clinical isolates suspicious for B. pseudomallei or clinical specimens from suspected melioidosis cases.

The strategy of international cooperation in the clinical laboratory field was analyzed to improve the quality of intervention by reviewing documents from international organizations and the Japanese government. Based on the world development agenda, the target of action for health has shifted from communicable diseases to non-communicable diseases (NCD). This emphasizes the importance of comprehensive clinical laboratories instead of disease-specific examinations in developing countries. To achieve this goal, the World Health Organization (WHO) has disseminated to the African and Asian regions the Laboratory Quality Management System (LQMS), which is based on the same principles of the International Organization of Standardization (ISO) 15189. To execute this strategy, international experts must have competence in project management, analyze information regarding the target country, and develop a strategy for management of the LQMS with an understanding of the technical aspects of laboratory work. However, there is no appropriate pre- and post-educational system of international health for Japanese international workers. Universities and academic organizations should cooperate with the government to establish a system of education for international workers. Objectives of this education system must include: (1) training for the organization and understanding of global health issues, (2) education of the principles regarding comprehensive management of clinical laboratories, and (3) understanding the LQMS which was employed based on WHO's initiative. Achievement of these objectives will help improve the quality of international cooperation in the clinical laboratory field.
Murine tumours have been used extensively to investigate the effects of heat and radiation, but there are significant differences between controlled laboratory studies and relatively uncontrolled clinical experience. From 1983 to 1986 a simple clinical system was developed in order to investigate biological questions in the clinic. This involved identifying a suitable patient population, reliable heating and thermometry, and methods of evaluating response of human tumours and their vasculature. (author)

Clinical and forensic toxicology can be defined as the two disciplines involved the detection, identification and measurement of xenobiotics in biological and non-biological specimens to help in the diagnosis, treatment, prognosis, prevention of poisonings and to disclose causes and contributory causes of fatal intoxications, respectively. This article explores the close connections between clinical and forensic toxicology in overlapping areas of interest. An update has been carried out of the following seven areas of interest in analytical toxicology: doping control, sudden cardiac death (SCD), brain death, sudden infant death syndrome (SIDS) and Munchausen syndrome by proxy (MSBP), prenatal exposure to drugs and fetal alcohol syndrome (FAS), drug-facilitated crimes (DFC) and intoxications by new psychoactive substances (NPS). While issues such as SCD, SIDS or doping control are investigated mainly in forensic laboratories, other as prenatal exposure to drugs or FAS are mainly treated in clinical laboratories. On the other hand, areas such MSBP, DFC or the intoxications by NPS are of interest in both laboratories. Some of these topics are initially treated in hospital emergency departments, involving clinical laboratories and sometimes lately derived to forensic laboratories. Conversely, cases with initial medical-legal implications and fatalities are directly handled by forensic toxicology, but may trigger further studies in the clinical setting. Many areas of common interest between clinical and forensic laboratories are building bridges between them. The increasing relationships are improving the growth, the reliability and the robustness of both kind of laboratories.

To provide a preliminary report of data from 2 support groups for single mothers, all of whom were mothers of children attending a child outpatient psychiatric clinic. The groups' 2 purposes were: 1. to assess the feasibility of adding structured evaluation to a common clinical intervention; 2. to improve single mothers' parenting skills through raised levels of self-esteem, increased capacity for family functioning and reduced levels of depression. Three structured evaluation instruments were used to measure the domains of self-esteem, family functioning and depression. These instruments were given to both groups of women on 3 occasions: 1. before the group; 2. after the group; 3. at a follow-up session 4 months after group termination. Open-ended questions were also asked at group termination. The questionnaire response rate was 100%; overall response rate for the 3 open-ended questions was 89%. Comparisons of pre-group and post-group scores showed that there was a significant increase in self-esteem (p parenting skills. Methodologic concerns and future directions are discussed.

The number of commercial laboratories for clinical testing in Japan run privately has decreased to about 30 companies, and their business is getting tougher. Branch Lab. and FMS businesses have not expanded recently due to the new reimbursement system which adds an additional sample management fee, becoming effective in 2010. This presentation gives an outline of each role for hospital and commercial laboratories, and their pros & cons considering the current medical situation. Commercial laboratories have investigated how to utilize ICT systems for sharing test information between hospitals and our facilities. It would be very helpful to clarify issues for each hospital. We will develop and create new values for clinical laboratory testing services and forge mutually beneficial relationships with medical institutions. (Review).

More than 50 Norwegian public and private laboratories provide one or more analyses for therapeutic drug monitoring or testing for drugs of abuse. Practices differ among laboratories, and analytical repertoires can change rapidly as new substances become available for analysis. The Pharmacology Portal was developed to provide an overview of these activities and to standardize the practices and terminology among laboratories. The Pharmacology Portal is a modern dynamic web database comprising all available analyses within therapeutic drug monitoring and testing for drugs of abuse in Norway. Content can be retrieved by using the search engine or by scrolling through substance lists. The core content is a substance registry updated by a national editorial board of experts within the field of clinical pharmacology. This ensures quality and consistency regarding substance terminologies and classification. All laboratories publish their own repertoires in a user-friendly workflow, adding laboratory-specific details to the core information in the substance registry. The user management system ensures that laboratories are restricted from editing content in the database core or in repertoires within other laboratory subpages. The portal is for nonprofit use, and has been fully funded by the Norwegian Medical Association, the Norwegian Society of Clinical Pharmacology, and the 8 largest pharmacologic institutions in Norway. The database server runs an open-source content management system that ensures flexibility with respect to further development projects, including the potential expansion of the Pharmacology Portal to other countries.

Patients with epilepsy (PWEs) and patients with nonepileptic seizures (PWNESs) constitute particularly vulnerable patient populations and have high rates of psychiatric comorbidities. This potentially decreases quality of life and increases health-care utilization and expenditures. However, lack of access to care or concern of stigma may preclude referral to outpatient psychiatric clinics. Furthermore, the optimal treatment for NESs includes longitudinal psychiatric management. No published literature has assessed the impact of colocated psychiatric services within outpatient epilepsy clinics. We, therefore, evaluated the colocation of psychiatric services within a level 4 epilepsy center. From July 2013 to June 2014, we piloted an intervention to colocate a psychiatrist in the Dartmouth-Hitchcock Epilepsy Center outpatient clinic one afternoon a week (0.1 FTE) to provide medication management and time-limited structural psychotherapeutic interventions to all patients who scored greater than 15 on the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) and who agreed to referral. Psychiatric symptom severity was assessed at baseline and follow-up visits using validated scales including NDDI-E, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and cognitive subscale items from Quality of Life in Epilepsy-31 (QOLIE-31) scores. Forty-three patients (18 males; 25 females) were referred to the clinic over a one-year interval; 27 (64.3%) were seen in follow-up with a median of 3 follow-up visits (range: 1 to 7). Thirty-seven percent of the patients had NESs exclusive of epilepsy, and 11% of the patients had dual diagnosis of epilepsy and NESs. Psychiatric symptom severity decreased in 84% of the patients, with PHQ-9 and GAD-7 scores improving significantly from baseline (4.6±0.4 SD improvement in PHQ-9 and 4.0±0.4 SD improvement in GAD-7, p-valuesintegrated models of collaborative and colocated care are becoming more

Full Text Available Background: Psychiatric disorders are common in patients attending neurology clinics with headache. Evaluation of psychiatric comorbidity in patients with headache is often missed in the busy neurology clinics. Aims: To assess the prevalence of Axis-I DSM-IV psychiatric disorders in patients with primary headache disorders in a rural-based tertiary neurology clinic in Western India. Settings and Design : A cross-sectional observation survey was conducting assessing all patients with migraine, tension-type headache and chronic daily headache attending the Neurology Clinic of Shree Krishna Hospital, a rural medical teaching hospital in Karamsad, in Gujarat in Western India. Materials and Methods: A total of 101 consecutive consenting adults with headache were interviewed using Mini International Neuropsychiatric Interview (M.I.N.I., a structured diagnostic clinical interview to assess prevalence of Axis-I DSM-IV psychiatric disorders. Statistical Analysis: Descriptive statistics were calculated using SPSS software version 16 and a binomial regression model was used to study the relationship of psychiatric co-morbidity with patient-related factors. Results: 49 out of 101 (48.5% patients with headache suffered from depressive disorders (dysthymia or depression or suicidality, 18 out of 101 patients with headache (17.90% suffered from anxiety related disorders (generalized anxiety disorder or agoraphobia or social phobia or panic disorder. Conclusions: Axis-I psychiatric disorders are a significant comorbidity among patients with headache disorders. M.I.N.I. can be used as a short, less time consuming instrument to assess all patients with headache disorders.

To determine essential content areas of immunology/serology courses at the clinical laboratory technician (CLT) and clinical laboratory scientist (CLS) levels. A questionnaire was designed which listed all major topics in immunology and serology. Participants were asked to place a check beside each topic covered. For an additional list of serological and immunological laboratory testing, participants were asked to indicate if each test was performed in either the didactic or clinical setting, or not performed at all. A national survey of 593 NAACLS approved CLT and CLS programs was conducted by mail under the auspices of ASCLS. Responses were obtained from 158 programs. Respondents from all across the United States included 60 CLT programs, 48 hospital-based CLS programs, 45 university-based CLS programs, and 5 university-based combined CLT and CLS programs. The survey was designed to enumerate major topics included in immunology and serology courses by a majority of participants at two distinct educational levels, CLT and CLS. Laboratory testing routinely performed in student laboratories as well as in the clinical setting was also determined for these two levels of practitioners. Certain key topics were common to most immunology and serology courses. There were some notable differences in the depth of courses at the CLT and CLS levels. Laboratory testing associated with these courses also differed at the two levels. Testing requiring more detailed interpretation, such as antinuclear antibody patterns (ANAs), was mainly performed by CLS students only. There are certain key topics as well as specific laboratory tests that should be included in immunology/serology courses at each of the two different educational levels to best prepare students for the workplace. Educators can use this information as a guide to plan a curriculum for such courses.

Objective: Computer and gaming-station use has become entrenched in the culture of our youth. Parents of children with psychiatric disorders report concerns about overuse, but research in this area is limited. The goal of this study is to evaluate computer/gaming-station use in adolescents in a psychiatric clinic population and to examine the relationship between use and functional impairment. Method: 102 adolescents, ages 11–17, from out-patient psychiatric clinics participated. Amount of computer/gaming-station use, type of use (gaming or non-gaming), and presence of addictive features were ascertained along with emotional/functional impairment. Multivariate linear regression was used to examine correlations between patterns of use and impairment. Results: Mean screen time was 6.7±4.2 hrs/day. Presence of addictive features was positively correlated with emotional/functional impairment. Time spent on computer/gaming-station use was not correlated overall with impairment after controlling for addictive features, but non-gaming time was positively correlated with risky behavior in boys. Conclusions: Youth with psychiatric disorders are spending much of their leisure time on the computer/gaming-station and a substantial subset show addictive features of use which is associated with impairment. Further research to develop measures and to evaluate risk is needed to identify the impact of this problem. PMID:21541096

Assessing dangerousness to gauge the likelihood of future violent behaviour has become an integral part of clinical mental health practice in forensic and non-forensic psychiatric settings, one of the most effective instruments for this being the Historical, Clinical and Risk Management-20 (HCR-20). To examine the HCR-20 factor structure in Mexican psychiatric inpatients and to obtain its predictive validity and reliability for use in this population. In total, 225 patients diagnosed with psychotic, affective or personality disorders were included. The HCR-20 was applied at hospital admission and violent behaviours were assessed during psychiatric hospitalization using the Overt Aggression Scale (OAS). Construct validity, predictive validity and internal consistency were determined. Violent behaviour remains more severe in patients classified in the high-risk group during hospitalization. Fifteen items displayed adequate communalities in the original designated domains of the HCR-20 and internal consistency of the instruments was high. The HCR-20 is a suitable instrument for predicting violence risk in Mexican psychiatric inpatients.

Often, baccalaureate nursing students initially approach a psychiatric mental health practicum with uncertainty, and even fear. They may feel unprepared for the myriad complex practice situations encountered. In addition, memories of personal painful life events may be vicariously evoked through learning about and listening to the experiences of those diagnosed with mental disorders. When faced with such challenging situations, nursing students often seek counsel from the clinical and/or classroom faculty. Pedagogic boundaries may begin to blur in the face of student distress. For the nurse educator, several questions arise: Should a nurse educator provide counseling to students? How does one best negotiate the boundaries between 'counselor', and 'caring educator'? What are the limits of a caring and professional pedagogic relation? What different knowledges provide guidance and to what differential consequences for ethical pedagogic relationships? This paper offers a comparative analysis of three philosophical stances to examine differences in key assumptions, pedagogic positioning, relationships of power/knowledge, and consequences for professional ethical pedagogic practices. While definitive answers are difficult, the authors pose several questions for consideration in discerning how best to proceed and under what particular conditions.

Mental health legislation represents an important mean of protecting the rights of persons with mental disabilities by preventing human rights violations and discrimination and by legally reinforcing the objectives of a mental health policy. The last decade has seen significant changes in the laws relating to psychiatric practice all over the world, especially with the implementation of the Convention for the Rights of People with Disabilities (CRPD). In this paper, we review the existing legislation in Lebanon concerning the following areas in mental health: treatment and legal protection of persons with mental disabilities, criminal laws in relation to offenders with mental disorders, and laws regulating incapacity. We will discuss these texts in comparison with international recommendations and standards on the rights of persons with disabilities, showing the recurrent contradiction between them. Throughout our article, we will address the clinical dilemmas that Lebanese psychiatrists encounter in practice, in the absence of a clear legislation that can orient their decisions and protect their patients from abuse.

Gender is an important variable in the study of mental health because of the actual and perceived differences between men and women. Relatively little is known how males and females differ in their manifestations of antisocial personality disorder (ASPD). Demographic and clinical features of 323 participants with ASPD were assessed and recorded. Women had fewer episodes of antisocial behavior involving or not involving police, higher scores on the Childhood Trauma Questionnaire (CTQ) and on Emotional Abuse and Sexual Abuse subscales of the CTQ compared to men. CTQ scores positively correlated with the number of episodes of antisocial behavior involving police in men but not in women. The percentage of patients with comorbid borderline and histrionic personality disorders was higher and the percentage of participants with cocaine use disorder was lower among women compared to men. Comorbid alcohol use disorder was frequent in both groups, while a higher percentage of women had comorbid mood disorders compared to men. Logistic regression analysis demonstrates that CTQ scores, histrionic personality disorder, and antisocial behavior involving the police drive the difference between the groups. Our findings indicate that treatment of individuals with ASPD should focus on the management of comorbid psychiatric disorders. Published by Elsevier Ireland Ltd.
The effects of autogenic training for anxiety disorders were investigated in a psychiatric setting of a medical school hospital and the predictors of this treatment outcome were identified. Fifty-five patients who meet the DSM-III-R criteria for anxiety disorders were treated individually with autogenic training by the author from October 1981 to October 1995. The medical records of the patients were investigated retrospectively. The results showed that the autogenic training was successful. Twenty-eight patients (51%) were cured, fourteen (25%) much improved, eight (15%) improved and five (9%) unchanged at the end of the treatment. Forty-two patients (76%) were assessed as having had successful treatment. Pretreatment variables, such as patient's clinical characteristics, did not provide a useful guide to the outcome. Four treatment variables did have a bearing on outcome. First, practicing the second standard autogenic training exercise was a satisfactory predictor of a better outcome. Second, practicing generalization training also was a useful predictor. Third, the application of other behavioral treatment techniques was found to be positively associated with outcome. Fourth, longer treatment periods were associated with a better outcome. These findings suggested that autogenic training could be of significant benefit for the treatment of anxiety disorders.

To design, implement, and evaluate student performance on clinically relevant chemical and spectral laboratory exercises on antibiotics. In the first of 2 exercises, second-year pharmacy students enrolled in an integrated laboratory sequence course studied the aqueous stability of ß-lactam antibiotics using a spectral visual approach. In a second exercise, students studied the tendency of tetracycline, rifamycins, and fluoroquinolones to form insoluble chelate complexes (turbidity) with polyvalent metals. On a survey to assess achievement of class learning objectives, students agreed the laboratory activities helped them better retain important information concerning antibiotic stability and interactions. A significant improvement was observed in performance on examination questions related to the laboratory topics for 2012 and 2013 students compared to 2011 students who did not complete the laboratory. A 1-year follow-up examination question administered in a separate course showed >75% of the students were able to identify rifamycins-food interactions compared with laboratory exercises. The use of spectral visual approaches allowed students to investigate antibiotic stability and interactions, thus reinforcing the clinical relevance of medicinal chemistry. Students' performance on questions at the 1-year follow-up suggested increased retention of the concepts learned as a result of completing the exercises.
Full Text Available Abstract Background Mental distress among medical students is often reported. Burnout has not been studied frequently and studies using interviewer-rated diagnoses as outcomes are rarely employed. The objective of this prospective study of medical students was to examine clinically significant psychiatric morbidity and burnout at 3rd year of medical school, considering personality and study conditions measured at 1st year. Methods Questionnaires were sent to 127 first year medical students who were then followed-up at 3rd year of medical school. Eighty-one of 3rd year respondents participated in a diagnostic interview. Personality (HP5-i and Performance-based self-esteem (PBSE-scale were assessed at first year, Study conditions (HESI, Burnout (OLBI, Depression (MDI at 1st and 3rd years. Diagnostic interviews (MINI were used at 3rd year to assess psychiatric morbidity. High and low burnout at 3rd year was defined by cluster analysis. Logistic regressions were used to identify predictors of high burnout and psychiatric morbidity, controlling for gender. Results 98 (77% responded on both occasions, 80 (63% of these were interviewed. High burnout was predicted by Impulsivity trait, Depressive symptoms at 1st year and Financial concerns at 1st year. When controlling for 3rd year study conditions, Impulsivity and concurrent Workload remained. Of the interviewed sample 21 (27% had a psychiatric diagnosis, 6 of whom had sought help. Unadjusted analyses showed that psychiatric morbidity was predicted by high Performance-based self-esteem, Disengagement and Depression at 1st year, only the later remained significant in the adjusted analysis. Conclusion Psychiatric morbidity is common in medical students but few seek help. Burnout has individual as well as environmental explanations and to avoid it, organisational as well as individual interventions may be needed. Early signs of depressive symptoms in medical students may be important to address. Students

This article describes information systems as a quality management tool in clinical laboratories. The quality of laboratory analyses is of fundamental importance for health professionals in aiding appropriate diagnosis and treatment. Information systems allow the automation of internal quality management processes, using standard sample tests, Levey-Jennings charts and Westgard multirule analysis. This simplifies evaluation and interpretation of quality tests and reduces the possibility of human error. This study proposes the development of an information system with appropriate functions and costs for the automation of internal quality control in small and medium-sized clinical laboratories. To this end, it evaluates the functions and usability of two commercial software products designed for this purpose, identifying the positive features of each, so that these can be taken into account during the development of the proposed system.

The aim of the study was to analyze the relationships between clinical variables (the severity of depression symptoms, feelings towards the body, dissociation, number and type of traumatic events) and deliberate self-injury functions. Moreover, we investigated whether the of group self-mutilating adolescents is internally diverse in terms of how important individual functions of self-mutilation are, and whether the subgroups singled out by these functions differ between each other in terms of clinical variables. The Inventory of Statements about Self-Injury was used. Characterizations of examined individuals and other research tools are included in our previous article (year, issue, pages). Associated with negative feelings towards the body are the functions of self-injuries (anti-dissociation, self-punishment) that can be described as interpersonal. High levels of depression symptoms (self-depreciation included) are mainly associated with the self-injury functions: self-punishment, anti-dissociation, establishing interpersonal boundaries. Affect regulation becomes more important as a function of self-inflicted injuries in cases of biological dysregulation and intense dissociative symptoms. The adolescents psychiatric inpatients are internally diverse in terms of dominant functions of self-injuries, which can be categorized into intra- and interpersonal. Intrapersonal functions dominate when an individual experiences severe depression, dissociative symptoms, and negative feelings towards the body. In cases of moderate intensity of depression, dissociative symptoms and negative feelings towards the body, both intrapersonal and interpersonal functions of self-mutilation are similarly important. Further research is required to explain the lowest severity of depression symptoms, dissociative symptoms and negative feelings towards the body co-occurs with no awareness of self-injuries functions.

The selection criteria used in clinical trials for smoking cessation and in laboratory studies that seek to understand mechanisms responsible for treatment outcomes may limit their generalizability to one another and to the general population. We reviewed studies on varenicline versus placebo and compared eligibility criteria and participant characteristics of clinical trials (N=23) and laboratory studies (N=22) across study type and to nationally representative survey data on adult, daily USA smokers (2014 National Health Interview Survey; 2014 National Survey on Drug Use and Health). Relative to laboratory studies, clinical trials more commonly reported excluding smokers who were unmotivated to quit and for specific medical conditions (e.g., cardiovascular disease, COPD), although both study types frequently reported excluding for general medical or psychiatric reasons. Laboratory versus clinical samples smoked less, had lower nicotine dependence, were younger, and more homogeneous with respect to smoking level and nicotine dependence. Application of common eligibility criteria to national survey data resulted in considerable elimination of the daily-smoking population for both clinical trials (≥47%) and laboratory studies (≥39%). Relative to the target population, studies in this review recruited participants who smoked considerably more and had a later smoking onset age, and were under-representative of Caucasians. Results suggest that selection criteria of varenicline studies limit generalizability in meaningful ways, and differences in criteria across study type may undermine efforts at translational research. Recommendations for improvements in participant selection and reporting standards are discussed. Copyright Â© 2016 Elsevier Ireland Ltd. All rights reserved.

The aim of the study was to explore whether a medical student education program and clinical posting in psychiatry had an impact on medical students' stigmatizing attitudes towards psychiatry and psychiatric disorders. Medical students from the University of Bordeaux were recruited during their 4-year course at the beginning of the academic education program in psychiatry. Medical students who were concomitantly in a clinical posting in wards of psychiatry or neurology were invited to participate in the study. The medical student version of the scale Mental Illness: Clinicians' Attitudes (MICA) was used to measure their attitudes towards psychiatry and persons with psychiatric disorder. This 16-item scale is designed to measure attitudes of health care professionals towards people with mental illness, a higher score indicating more stigmatizing attitudes. Items exploring history of psychiatric disorders in close persons were added at the end of the MICA scale. The questionnaire was completed twice by each student, at the beginning and the end of the 11-week clinical posting. All questionnaires were strictly anonymized. Multivariate linear regression analyses were used to identify the variables independently associated with MICA total score. At the beginning of the education program and clinical posting, 174 students completed the MICA scale: the mean MICA total score was equal to 46.4 (SD 6.9) in students in clinical posting in psychiatry (n=72) and 45.1 (SD 7.01) in those in neurology (n=102). At the end of the academic and clinical training, 138 students again completed the questionnaire, with mean MICA total scores equal to 41.4 (SD 8.1) in students in clinical posting in psychiatry (n=51) and 43.5 (SD 7.3) in those in neurology (n=87). Multivariate analyses showed that lower total MICA scores were independently associated with the time of assessment (lower scores at the end of education program and clinical posting) (b=-2.8; P=0.001), female gender (b=-1.8; P=0

a) to examine the demographic and clinical characteristics of repeat-presentations to an adolescent urgent psychiatric clinic, and b) to compare them with single-time presentation. This 18-month retrospective study compared repeat-presenters to age and gender matched single-time presenters. Demographic variables included age gender and ethnicity. Clinical variables included reason for referral, family history, diagnosis, recommendations and compliance. Data were analyzed using descriptive statistics, McNemar's Chi-square tests for matched pairs, and conditional logistic regression. Of 624 assessments 24% (N=151) were repeat-presentations. Compared with single-presentation, repeat-presentation group had a higher proportion of Aboriginal youth (X2 (1) = 108.28 p presentation group had higher odds of past hospital admission (OR: 3.50, p presentations for urgent psychiatric consultation constitute a quarter of referrals to the urgent psychiatric clinic. Identifying and addressing factors that contribute to repeat-presentations may, assist in improving treatment compliance by ensuring focused interventions and service delivery for these youth. In turn, this will improve access to the limited urgent services for other youth.

Objective To report on the prevalence of psychiatric comorbidity and its association with illness severity in depressed HIV patients. Methods As part of a multi-site randomized controlled trial of depression treatment for HIV patients, 304 participants meeting criteria for current Major Depressive Disorder (MDD) were assessed for other mood, anxiety and substance use disorders with the Mini-International Neuropsychiatric Interview, a structured psychiatric diagnostic interview. We also assessed baseline adherence, risk, and health measures. Results Complicated depressive illness was common. Only 18% of participants experienced MDD with no comorbid psychiatric diagnoses; 49% had comorbid dysthymia, 62% had ≥1 comorbid anxiety disorder, and 28% had a comorbid substance use disorder. Self-reported antiretroviral adherence did not differ by the presence of psychiatric comorbidity. However, psychiatric comorbidity was associated with worse physical health and functioning: compared to those with MDD alone, individuals with ≥1 comorbidity reported more HIV symptoms (5.1 vs. 4.1, p-value=0.01), and worse mental health-related quality of life on the SF-12 (29 vs. 35, p<0.01). Conclusion For HIV patients with MDD, chronic depression and psychiatric comorbidity are strikingly common, and this complexity is associated with greater HIV disease severity and worse quality of life. Appreciating this comorbidity can help clinicians better target those at risk of harder-to-treat HIV disease, and underscores the challenge of treating depression in this population. PMID:25892152

Drugs sometimes alter the results of clinical laboratory tests. We examined the effects of pralidoxime (PAM) salts, a medicine used to treat organophosphorus poisoning, on clinical laboratory test results for the first time. The effects of PAM salts on glucose (GLU) measurements were examined using a point-of-care testing (POCT) meter, four self-monitoring of blood glucose (SMBG) meters, and two biochemical autoanalyzers. The effects of PAM salts on other clinical tests were also evaluated. The addition of PAM iodide or potassium iodide, but not of PAM chloride or potassium chloride, to blood samples increased the GLU values measured by one POCT meter and 4 SMBG meters using the enzyme electrode (hydrogen peroxidase or oxygen electrode) method. On the other hand, PAM iodide or PAM chloride, but not KI or KCl, affected the values measured at 340 nm by an autoanalyzer using absorption spectrophotometry in 8 of 14 clinical laboratory tests. The absorption spectrum of PAM changed from 294 to 338 nm due to the reaction between PAM and the alkaline buffer, a component of the measuring reagents. PAM iodide increases the GLU values measured by the enzyme electrode method, and PAM salts affected the values measured at 340 nm by absorption spectrophotometry in many other clinical test items.

Clinical skills laboratories have been established in medical institutions as facilities for simulation-based medical education (SBME). SBME is believed to be superior to the traditional style of medical education from the viewpoint of the active and adult learning theories. SBME can provide a learning cycle of debriefing and feedback for learners as well as evaluation of procedures and competency. SBME offers both learners and patients a safe environment for practice and error. In a full-environment simulation, learners can obtain not only technical skills but also non-technical skills, such as leadership, team work, communication, situation awareness, decision-making, and awareness of personal limitations. SBME is also effective for integration of clinical medicine and basic medicine. In addition, technology-enhanced simulation training is associated with beneficial effects for outcomes of knowledge, skills, behaviors, and patient-related outcomes. To perform SBME, effectively, not only simulators including high-fidelity mannequin-type simulators or virtual-reality simulators but also full-time faculties and instructors as professionals of SBME are essential in a clinical skills laboratory for SBME. Clinical skills laboratory is expected to become an integrated medical education center to achieve continuing professional development, integrated learning of basic and clinical medicine, and citizens' participation and cooperation in medical education.

Objectives: To propose a new conceptual model to gain insight and analyse factors that influence the laboratory–clinical staff interface. Methods: To develop the conceptual model, a literature study was performed, regulatory guidelines and standards for laboratories were analysed and discussions were held with experts on the topic. Result: A conceptual model and analytical framework provided good guidance in understanding and assessing the organisational and personal factors shaping the interface. The model was based on three elements: (1 the three phases of communication (pre-analytical, analytical and post-analytical; (2 the organisational and personal factors of interaction; and (3 the socio-political, economic and cultural context in which clinicians and laboratory staff operate. Conclusion: Assessment of the interface between clinicians and laboratory workers can be performed in a systematic way. Applying this model will provide information to managers of health institutions and heads of laboratories and clinical departments about what happens when clinicians and laboratory staff interact, thus aiding them in designing strategies to improve this interface.

An increasing number of veterinary laboratories worldwide have obtained or are seeking certification based on international standards, such as the International Organization for Standardization/International Electrotechnical Commission 17025. Compliance with any certification standard or quality management system requires quality documentation, an activity that may present several unique challenges in the case of veterinary laboratories. Research specifically addressing quality documentation is conspicuously absent in the veterinary literature. This article provides an overview of the quality system documentation needed to comply with a quality management system with an emphasis on preparing written standard operating procedures specific for veterinary laboratories. In addition, the quality documentation challenges that are unique to veterinary clinical pathology laboratories are critically evaluated against the existing quality standards and discussed with respect to possible solutions and/or recommended courses of action. Documentation challenges include the establishment of quality requirements for veterinary tests, the use or modification of human analytic methods for animal samples, the limited availability of quality control materials satisfactory for veterinary clinical pathology laboratories, the limited availability of veterinary proficiency programs, and the complications in establishing species-specific reference intervals.
Despite a huge number of published laboratory bonding studies on dental oxide ceramics clinical long-term studies on resin bonded oxide ceramic restorations are rare. The purpose of this review is to present the best available clinical evidence for successful bonding of dental oxide ceramic restorations. Clinical trials with resin-bonded restorations that had no or only limited mechanical retention and were made from alumina or zirconia ceramic were identified using an electronic search in PubMed database. Overall 10 publications with clinical trials could be identified. Their clinical outcome was compared with that laboratory bond strength studies. Clinical data provide strong evidence that air-abrasion at a moderate pressure in combination with using phosphate monomer containing primers and/or luting resins provide long-term durable bonding to glass-infiltrated alumina and zirconia ceramic under the humid and stressful oral conditions. As simple and clinically reliable bonding methods to oxide ceramics exist, the rationale for development of alternative bonding methods might be reconsidered especially when these methods are more time consuming or require rather complicated and/or technique sensitive procedures.

Despite an increasing focus on simulation as a learning strategy in nursing education, there is limited evidence on the transfer of simulated skills into clinical practice. Therefore it's important to increase knowledge of how clinical skills laboratories (CSL) can optimize students' learning for development of professional knowledge and skills, necessary for quality nursing practice and for patient safety. Thus, the aim was to describe nursing students' experiences of learning in the CSL as a preparation for their clinical practice. Interviews with 16 students were analysed with content analysis. An overall theme was identified - walking the bridge - in which the CSL formed a bridge between the university and clinical settings, allowing students to integrate theory and practice and develop a reflective stance. The theme was based on categories: conditions for learning, strategies for learning, tension between learning in the skills laboratory and clinical settings, and development of professional and personal competence. The CSL prepared the students for clinical practice, but a negative tension between learning in CSL and clinical settings was experienced. However, this tension may create reflection. This provides a new perspective that can be used as a pedagogical approach to create opportunities for students to develop their critical thinking. Copyright © 2015 Elsevier Ltd. All rights reserved.

Loxapine is a first generation antipsychotic, belonging to the dibenzoxazepine class. Recently, loxapine has been reformulated at a lower dose, producing an inhaled powder that can be directly administered to the lungs to treat the agitation associated with psychiatric disorders, such as schizophrenia and bipolar disorder. Thus, the aim of this narrative and clinical mini-review was to evaluate the efficacy and tolerability of inhaled loxapine in the treatment of acute agitation in patients w...

Competitive bidding to derive Medicare fees promises several advantages over administered fee systems. The authors show how incentives for cost savings, quality, and access can be incorporated into bidding schemes, and they report on a study of the clinical laboratory industry conducted in preparation for a bidding demonstration. The laboratory industry is marked by variable concentration across geographic markets and, among firms themselves, by social and economic heterogeneity. The authors conclude that these conditions can be accommodated by available bidding design options and by careful selection of bidding markets. PMID:10180003

Full Text Available Abstract Objective: This study aimed to describe and analyze clinical and laboratory characteristics of patients with sickle cell anemia treated at the Hemominas Foundation, in Divinópolis, Brazil. Furthermore, this study aimed to compare the clinical and laboratory outcomes of the group of patients treated with hydroxyurea with those patients that were not treated with hydroxyurea. Methods: Clinical and laboratorial data were obtained by analyzing medical records of patients with sickle cell anemia. Results: Data from the medical records of 50 patients were analyzed. Most of the patients were female (56%, aged between 20 and 29 years old. Infections, transfusions, cholecystectomy, splenectomy and systemic arterial hypertension were the most common clinical adverse events of the patients. The most frequent cause of hospitalization was painful crisis. The majority of patients had reduced values of hemoglobin and hematocrit (8.55 ± 1.33 g/dL and 25.7 ± 4.4%, respectively and increased fetal hemoglobin levels (12 ± 7%. None of the clinical variables was statistically significant on comparing the two groups of patients. Among hematological variables only hemoglobin and hematocrit levels were statistically different between patients treated with hydroxyurea and untreated patients (p-value = 0.005 and p-value = 0.001, respectively. Conclusion: Sickle cell anemia requires treatment and follow-up by a multiprofessional team. A current therapeutic option is hydroxyurea. This drug reduces complications and improves laboratorial parameters of patients. In this study, the use of the drug increased the hemoglobin and hematocrit levels of patients.

Duplicate laboratory tests that are unwarranted increase unnecessary phlebotomy, which contributes to iatrogenic anemia, decreased patient satisfaction, and increased health care costs. We employed a clinical decision support tool (CDST) to block unnecessary duplicate test orders during the computerized physician order entry (CPOE) process. We assessed laboratory cost savings after 2 years and searched for untoward patient events associated with this intervention. This CDST blocked 11,790 unnecessary duplicate test orders in these 2 years, which resulted in a cost savings of $183,586. There were no untoward effects reported associated with this intervention. The movement to CPOE affords real-time interaction between the laboratory and the physician through CDSTs that signal duplicate orders. These interactions save health care dollars and should also increase patient satisfaction and well-being.

Adolescents with substance use disorders are more likely to have a current psychiatric disorder. However, when compared with the adult literature, there is relatively limited information regarding the specific co-occurrence of certain mental health diagnoses and substance use disorders in adolescents. The objectives of this study were to build on the previous literature regarding mental health diagnoses and different types of substance use disorders in adolescents, as well as explore the differences, if any, between groupings of mental health diagnosis and type of substance used. Data were extracted from the clinical records of 483 individuals aged 11-24 years referred for an evaluation at the Adolescent Substance Abuse Program at Boston Children's Hospital. According to DSM-IV-Text Revision criteria, individuals received diagnoses of substance abuse or dependence and any additional psychiatric disorders. Problematic use was included within the sample for greater power analysis. A multivariable logistic regression model estimated the association between psychiatric diagnosis and substance use while adjusting for covariates including age and gender. Multiple significant associations were found, including having any anxiety-related diagnosis and opioid use (odds ratio [OR] = 2.23, p < .001), generalized anxiety disorder and opioids (OR = 3.42, p = .008), cocaine and post-traumatic stress disorder (OR = 3.61, p = .01), and marijuana and externalizing behavior disorders (OR = 2.10, p = .024). Our study found multiple significant associations between specific substances and certain co-occurring psychiatric disorders. The use of office screening systems to efficiently identify these youths should be a part of routine medical and psychiatric care. Copyright © 2017 Society for Adolescent Health and Medicine.

Prior important research is not always cited, exemplified by Oswald Avery's pioneering discovery that DNA is the genetic transforming factor; it was not cited by Watson and Crick 10 years later. My first laboratory research (National Institutes of Health 1950s) resulted in the clinical development of transseptal left heart catheterization. Laboratory studies on cardiac muscle mechanics in normal and failing hearts led to the concept of afterload mismatch with limited preload reserve. At the University of California, San Diego in La Jolla (1968) laboratory experiments on coronary artery reperfusion after sustained coronary occlusion showed salvage of myocardial tissue, a potential treatment for acute myocardial infarction proven in clinical trials of thrombolysis 14 years later. Among 60 trainees who worked with me in La Jolla, one-third were Japanese and some of their important laboratory experiments are briefly recounted, beginning with Sasayama, Tomoike and Shirato in the 1970 s. Recently, we developed a method for cardiac gene transfer, and subsequently we showed that gene therapy for the defect in cardiomyopathic hamsters halted the progression of advanced disease. Cardiovascular research and medicine are producing continuing advances in technologies for gene transfer and embryonic stem cell transplantation, targeting of small molecules, and tissue and organ engineering.

This article highlights technology innovations in psychiatric and medical education, including applications from other fields. The authors review the literature and poll educators and informatics faculty for novel programs relevant to psychiatric education. The introduction of new technologies requires skill at implementation and evaluation to assess the pros and cons. There is a significant body of literature regarding virtual reality and simulation, including assessment of outcomes, but other innovations are not well studied. Innovations, like other uses of technology, require collaboration between parties and integration within the educational framework of an institution.

Training in psychiatric settings is stressful for nursing students. The purpose of this study was to examine the correlations between the students' characteristics, their stress degrees, stressors and types of coping strategies they experience during training in psychiatric course. A descriptive, correlational, longitudinal design was used. Sixty-five undergraduate nursing students were recruited randomly from five Jordanian universities. Self-report questionnaires were administered at the second semester of the 2012-2013 academic year. The findings showed that students who utilized avoidance or transference strategies reported high stress degrees. Moreover, the results showed that those students who were in the fourth year, with a low family income, who avoid extracurricular activities, with a low academic grade or who registered in other clinical course(s) reported high stress degrees. These findings present a worthy data for the clinical instructors that facilitate students training in psychiatric settings and promote their psychosocial well-being.

The purpose of this paper is to describe the attitudes and perceptions among college biology and CLS/CLT students. These students were on selected college campuses at Texas universities in Houston, Dallas and the Austin/San Antonio areas for the Spring 2007 semester. Specifically, students were questioned on factors that influence their choice of field of study, career expectations, legislative measures which might be used to attract individuals to the career, and factors that will be required to keep them in the field of practice. This study was part of a larger qualitative study which included exploratory discovery and inductive logic regarding the attitudes of four focus groups in Texas. Focus groups took place on college campuses or in hotel conference rooms. (1) junior/senior-level college biology students and (2) junior/senior-level students currently enrolled in CLS/CLT programs. Focus group discussions using a standard set of questions; group sessions lasted about 45 minutes. This study was a qualitative study which included exploratory discovery and inductive logic regarding the attitudes of two groups in Texas. College biology and CLS/CLT students find the clinical laboratory science profession to be interesting and exciting as a career prospect, however, many do not see themselves remaining in the profession and perceive it does not have good prospects for career advancement. The majority of students must work to support themselves through their college education and would welcome additional grants, scholarships and loan forgiveness programs as incentives to study the clinical laboratory sciences. Students believe that additional recruitment on high school and college campuses is needed to increase the visibility of the field as career choice. The majority of students who are entering the clinical laboratory science profession do not see the profession as their final career choice, but rather a stepping stone to another career field in healthcare or a

We linked extensive longitudinal data from the Swedish national eating disorders quality registers and patient registers to explore clinical characteristics at diagnosis, diagnostic flux, psychiatric comorbidity, and suicide attempts in 850 individuals diagnosed with binge-eating disorder (BED). Cases were all individuals who met criteria for BED in the quality registers (N = 850). We identified 10 controls for each identified case from the Multi-Generation Register matched on sex, and year, month, and county of birth. We evaluated characteristics of individuals with BED at evaluation and explored diagnostic flux across eating disorders presentations between evaluation and one-year follow-up. We applied conditional logistic regression models to assess the association of BED with each comorbid psychiatric disorder and with suicide attempts and explored whether risk for depression and suicide were differentially elevated in individuals with BED with or without comorbid obesity. BED shows considerable diagnostic flux with other eating disorders over time, carries high psychiatric comorbidity burden with other eating disorders (OR 85.8; 95 % CI: 61.6, 119.4), major depressive disorder (OR 7.6; 95 % CI: 6.2, 9.3), bipolar disorder (OR 7.5; 95 % CI: 4.8, 11.9), anxiety disorders (OR 5.2; 95 % CI: 4.2, 6.4), and post-traumatic stress disorder (OR 4.3; 95 % CI: 3.2, 5.7) and is associated with elevated risk for suicide attempts (OR 1.8; 95 % CI: 1.2, 2.7). Depression and suicide attempt risk were elevated in individuals with BED with and without comorbid obesity. Considerable flux occurs across BED and other eating disorder diagnoses. The high psychiatric comorbidity and suicide risk underscore the severity and clinical complexity of BED.

To validate the performance, reproducibility, and reliability of BD automated instruments in order to establish a fully automated clinical microbiology laboratory. We used control strains and clinical samples to assess the accuracy, reproducibility, and reliability of the BD Kiestra WCA, the BD Phoenix, and BD Bruker MALDI-Biotyper instruments and compared them to previously established conventional methods. The following processes were evaluated: sample inoculation and spreading, colony counts, sorting of cultures, antibiotic susceptibility test, and microbial identification. The BD Kiestra recovered single colonies in less time than conventional methods (e.g. E. coli, 7h vs 10h, respectively) and agreement between both methodologies was excellent for colony counts (κ=0.824) and sorting cultures (κ=0.821). Antibiotic susceptibility tests performed with BD Phoenix and disk diffusion demonstrated 96.3% agreement with both methods. Finally, we compared microbial identification in BD Phoenix and Bruker MALDI-Biotyper and observed perfect agreement (κ=1) and identification at a species level for control strains. Together these instruments allow us to process clinical urine samples in 36h (effective time). The BD automated technologies have improved performance compared with conventional methods, and are suitable for its implementation in very busy microbiology laboratories. © American Society for Clinical Pathology 2017.

Recent Solid State Photomultiplier (SSPM) technology has matured, reaching a performance level that is suitable for replacement of the ubiquitous photomultiplier tube in selected applications for environmental radiation monitoring, clinical dosimetry, and medical imaging purposes. The objective of this work is low signal level laboratory and high signal level clinical testing of the Hamamatsu MPPC (S10362-11-050C), Photonique SSPM (0810G1), and Voxtel SiPM (SQBF-EKAA/SQBF-EIOA) SSPMs coupled to different inorganic scintillator crystals (Prelude 420, BGO), inorganic doped glass scintillator material SiO 2 :Cu 2+ and organic BCF-12 plastic scintillating fibers, used as detector elements. Plastic Optical Fibers (POFs) and Glass Optical Fibers (GOFs) are used as signal conduits for laboratory and clinical testing. Further, reduction of electron-beam-generated Cerenkov light in optical fibers is facilitated by the inclusion of metalized air-core capillary tubing between the BCF-12 plastic scintillating fiber and the POF. In a clinical setting dose linearity, percent depth dose, and angular measurements for 6 MV/18 MV photon beams and 9 MeV electron beams are compared with and without the use of the air-core capillary tubing for BCF-12 plastic scintillating fiber. These same measurements are repeated for SiO 2 :Cu 2+ scintillator material without air-core capillary tubing.

Full Text Available Background: Suicide by means of self-inflicted stab wounds is relatively uncommon and little is known about this population and their management. Materials and Methods: Retrospective review of adult trauma patients admitted to our Level-1 trauma center between January 2005 and October 2009 for management of non-fatal, self-inflicted stab wounds. Results: Fifty-eight patients were evaluated with self-inflicted stab wounds. Four patients died due to their injuries (mortality, 7%. Of the non-fatal stab wounds, 78% were male ranging in age from 19-82 (mean: 45 years. The most common injury sites were the abdomen (46%, neck (33%, and chest (20%. In terms of operative interventions, 56% of abdominal operations were therapeutic, whereas 100% of neck and chest operations were therapeutic. When assessing for suicidal ideation, 44 patients (81% admitted to suicidal intentions whereas 10 patients (19% described "accidental" circumstances. Following psychiatric evaluation, 8 of the 10 patients with "accidental injuries" were found to be suicidal. Overall, 54 patients (98% met criteria for a formal psychiatric diagnosis with 48 patients (89% necessitating inpatient or outpatient psychiatric assistance at discharge. Conclusions: Compared to previous reports of stab wounds among trauma patients, patients with self- inflicted stab wounds may have a higher incidence of operative interventions and significant injuries depending on the stab location. When circumstances surrounding a self-inflicted stabbing are suspicious, additional interviews by psychiatric care providers may uncover a suicidal basis to the event. Given the increased incidence of psychiatric illness in this population, it is imperative to approach the suicidal patient in a multidisciplinary fashion.

The incidence of Candida bloodstream infection (BSI) has been on the rise in several countries worldwide. Species distribution is changing; an increase in the percentage of non-albicans species, mainly fluconazole non-susceptible C. glabrata was reported. Existing microbiology diagnostic methods lack sensitivity, and new methods need to be developed or further evaluation for routine application is necessary. Although reliable, standardized methods for antifungal susceptibility testing are available, the determination of clinical breakpoints remains challenging. Correct species identification is important and provides information on the intrinsic susceptibility profile of the isolate. Currently, acquired resistance in clinical Candida isolates is rare, but reports indicate that it could be an issue in the future. The role of the clinical microbiology laboratory is to isolate and correctly identify the infective agent and provide relevant and reliable susceptibility data as soon as possible to guide antifungal therapy.

Training clinical laboratory science (CLS) students in techniques of preparation and delivery of an instructional unit is an important component of all CLS education programs and required by the national accrediting agency. Participants of this study included students admitted to the CLS program at Northern Illinois University and enrolled in the teaching course offered once a year between the years of 1997 and 2009. Courses on the topic of "teaching" may be regarded by CLS students as unnecessary. However, entry level practitioners are being recruited to serve as clinical instructors soon after entering the workforce. Evaluation of the data collected indicates that students are better prepared to complete tasks related to instruction of a topic after having an opportunity to study and practice skills of teaching. Mentoring CLS students toward the career role of clinical instructor or professor is important to maintaining the workforce.

Increasing numbers of clinical laboratories are transitioning away from flame and electrothermal AAS methods to those based on ICP-MS. Still, for many laboratories, the choice of instrumentation is based upon (a) the element(s) to be determined, (b) the matrix/matrices to be analyzed, and (c) the expected concentration(s) of the analytes in the matrix. Most clinical laboratories specialize in measuring Se, Zn, Cu, and Al in serum, and/or Pb, Cd, Hg, As, and Cr in blood and/or urine, while other trace elements (e.g., Pt, Au etc.) are measured for therapeutic purposes. Quantitative measurement of elemental species is becoming more widely accepted for nutritional and/or toxicological screening purposes, and ICP-MS interfaced with separation techniques, such as liquid chromatography or capillary electrophoresis, offers the advantage of on-line species determination coupled with very low detection limits. Polyatomic interferences for some key elements such as Se, As, and Cr require instrumentation equipped with dynamic reaction cell or collision cell technologies, or might even necessitate the use of sector field ICP-MS, to assure accurate results. Nonetheless, whatever analytical method is selected for the task, careful consideration must be given both to specimen collection procedures and to the control of pre-analytical variables. Finally, all methods benefit from access to reliable certified reference materials (CRMs). While a variety of reference materials (RMs) are available for trace element measurements in clinical matrices, not all can be classified as CRMs. The major metrological organizations (e.g., NIST, IRMM, NIES) provide a limited number of clinical CRMs, however, secondary reference materials are readily available from commercial organizations and organizers of external quality assessment schemes.

Still, for many laboratories, the choice of instrumentation is based upon (a) the element(s) to be determined, (b) the matrix/matrices to be analyzed, and (c) the expected concentration(s) of the analytes in the matrix. Most clinical laboratories specialize in measuring Se, Zn, Cu, and Al in serum, and/or Pb, Cd, Hg, As, and Cr in blood and/or urine, while other trace elements (e.g., Pt, Au etc.) are measured for therapeutic purposes. Quantitative measurement of elemental species is becoming more widely accepted for nutritional and/or toxicological screening purposes, and ICP-MS interfaced with separation techniques, such as liquid chromatography or capillary electrophoresis, offers the advantage of on-line species determination coupled with very low detection limits. Polyatomic interferences for some key elements such as Se, As, and Cr require instrumentation equipped with dynamic reaction cell or collision cell technologies, or might even necessitate the use of sector field ICP-MS, to assure accurate results. Nonetheless, whatever analytical method is selected for the task, careful consideration must be given both to specimen collection procedures and to the control of pre-analytical variables. Finally, all methods benefit from access to reliable certified reference materials (CRMs). While a variety of reference materials (RMs) are available for trace element measurements in clinical matrices, not all can be classified as CRMs. The major metrological organizations (e.g., NIST, IRMM, NIES) provide a limited number of clinical CRMs, however, secondary reference materials are readily available from commercial organizations and organizers of external quality assessment schemes

Full Text Available Introduction: Kikuchi-Fujimoto disease is an uncommon disorder with worldwide distribution, characterized by fever and benign enlargement of the lymph nodes, primarily affecting young adults. Awareness about this disorder may help prevent misdiagnosis and inappropriate investigations and treatment. The objective of the study was to evaluate the clinical and laboratory characteristics of histopathologically confirmed cases of Kikuchi′s disease from a tertiary care center in southern India. Materials and Methods: Retrospective analysis of all adult patients with histopathologically confirmed Kikuchi′s disease from January 2007 to December 2011 in a 2700-bed teaching hospital in South India was done. The clinical and laboratory characteristics and outcome were analyzed. Results: There were 22 histopathologically confirmed cases of Kikuchi′s disease over the 5-year period of this study. The mean age of the subjects′ was 29.7 years (SD 8.11 and majority were women (Male: female- 1:3.4. Apart from enlarged cervical lymph nodes, prolonged fever was the most common presenting complaint (77.3%. The major laboratory features included anemia (54.5%, increased erythrocyte sedimentation rate (31.8%, elevated alanine aminotransferase (27.2% and elevated lactate dehydrogenase (LDH (31.8%. Conclusion: Even though rare, Kikuchi′s disease should be considered in the differential diagnosis of young individuals, especially women, presenting with lymphadenopathy and prolonged fever. Establishing the diagnosis histopathologically is essential to avoid inappropriate investigations and therapy.

Quality control is an essential component in every clinical laboratory which maintains the excellence of laboratory standards, supplementing to proper disease diagnosis, patient care and resulting in overall strengthening of health care system. Numerous quality control schemes are available, with combinations of procedures, most of which are tedious, time consuming and can be "too technical" whereas commercially available quality control materials can be expensive especially for laboratories in developing nations like Nepal. Here, we present a procedure performed at our centre with self prepared control serum and use of simple statistical tools for quality assurance. The pooled serum was prepared as per guidelines for preparation of stabilized liquid quality control serum from human sera. Internal Quality Assessment was performed on this sample, on a daily basis which included measurement of 12 routine biochemical parameters. The results were plotted on Levey-Jennings charts and analysed with quality control rules, for a period of one month. The mean levels of biochemical analytes in self prepared control serum were within normal physiological range. This serum was evaluated every day along with patients' samples. The results obtained were plotted on control charts and analysed using common quality control rules to identify possible systematic and random errors. Immediate mitigation measures were taken and the dispatch of erroneous reports was avoided. In this study we try to highlight on a simple internal quality control procedure which can be performed by laboratories, with minimum technology, expenditure, and expertise and improve reliability and validity of the test reports.

We developed a Microsoft Access-based laboratory management system to facilitate database management of leukemia patients referred for cytogenetic tests in regards to karyotyping and fluorescence in situ hybridization (FISH). The database is custom-made for entry of patient data, clinical details, sample details, cytogenetics test results, and data mining for various ongoing research areas. A number of clinical research laboratoryrelated tasks are carried out faster using specific "queries." The tasks include tracking clinical progression of a particular patient for multiple visits, treatment response, morphological and cytogenetics response, survival time, automatic grouping of patient inclusion criteria in a research project, tracking various processing steps of samples, turn-around time, and revenue generated. Since 2005 we have collected of over 5,000 samples. The database is easily updated and is being adapted for various data maintenance and mining needs.

For the occasion of the 50th anniversary of the journal Clinical Chemistry and Laboratory Medicine (CCLM), an historic overview of papers that the journal has published in the field of laboratory hematology (LH) is presented. All past volumes of CCLM were screened for papers on LH and these were categorized. Bibliographic data of these papers were also analyzed. CCLM published in total 387 LH papers. The absolute number of LH papers published annually showed a significant increase over the years since 1985. Also the share of LH papers demonstrated a steady increase (overall mean 5%, but mean 8% over the past 4 years). The most frequent category was coagulation and fibrinolysis (23.5%). Authors from Germany contributed the most LH papers to the journal (22.7%), followed by the Netherlands and Italy (16.3 and 13.2%, respectively). Recent citation data indicated that other publications cited LH review papers much more frequently than other types of papers. The history of the journal reflects the emergence and development of laboratory hematology as a separate discipline of laboratory medicine.

Objective We aimed to examine the rates, correlates, methods, and precipitating factors of suicide attempts among adolescent patients admitted for psychiatric inpatient care from 1999 to 2010 in a university hospital in Korea. Methods The subjects consisted of 728 patients who were admitted for psychiatric inpatient care in a university hospital over a 12-year period and who were aged 10-19 years at the time of admission. We retrospectively investigated the information on suicidal behaviors and other clinical information by reviewing the subjects' electronic medical records. Whether these patients had completed their suicide on 31 December 2010 was determined by a link to the database of the National Statistical Office. Results Among 728 subjects, 21.7% had suicidal ideation at admission, and 10.7% admitted for suicidal attempts. Female gender, divorced/widowed parents, and the presence of mood disorders were associated with a significantly increased likelihood of suicide attempts. Most common method of suicide attempts was cutting, and most common reason for suicide attempts was relationship problems within the primary support group. A diagnosis of schizophrenia was associated with increased risk of death by suicide after discharge. Conclusion These results highlight the role of specific psychosocial factor (e.g., relational problems) and psychiatric disorders (e.g., mood disorders) in the suicide attempts of Korean adolescents, and the need for effective prevention strategies for adolescents at risk for suicide.

The hospital infection control and prevention is recognized to be more and more important according to the advances in modern medical treatment and care. Clinical microbiology laboratory play critical roles in the hospital infection control as a member of infection control team (ICT). They are the first in a hospital to identify outbreak of MRSA in NICU and molecular epidemiological analysis of the isolates lead proper intervention of ICT to the concerned ward. From a viewpoint of infectious disease specialist, rapid and precise microbiological information is essential for the appropriate diagnosis and treatment of infectious diseases. Each medical technologist need to make efforts to understand the characteristics of the examinations for infectious diseases and send out information useful for clinical practices. In our hospital, with the participation of all members of medical technologists, rapid reporting system was developed for blood culture examinations, which greatly contribute to the appropriate treatment of bloodstream infections. Collaborations of clinical microbiology laboratory with other members of ICT realize high quality hospital infection control. They also need to be aware of themselves as good practitioners of infection control measures to prevent hospital infections.

We present a survey of sex differences and socio-demographic and clinical variables in children and adolescents receiving a psychiatric consultation service in an emergency department (ED). This observational, retrospective, and cross-sectional study included all records of patients (age, services in an ED in a 4-year period (January 2010 to December 2013). Two hundred fifty-nine records of children and adolescents were located. The mean age of the participants was 14.19 years, and most subjects were female (59.5%) and had private health insurance (83.7%). Most participants (87.4%) were accompanied by their parents. The main complaints were suicide attempts (21.8%) and psychomotor agitation/aggressiveness (21.8%). Unipolar depression (37.8%) and adjustment, reactive, and anxiety disorders (13.7%) were the most prevalent diagnoses. Most patients received an indication of psychiatric hospitalization (51.7%). Females had more suicide attempts than males (28.3% vs 12.4%) and less psychomotor agitation/aggressiveness than males (15.5% vs 31.4%). Females also exhibited more unipolar depression (47.6% vs 23.5%), fewer psychotic disorders (4.2% vs 16.3%), and substance use/misuse (1.4% vs 13.3%) than males. Males needed more psychiatric medication during evaluation (37.9% vs 19.2%). This survey of the profile of pediatric patients evaluated by a psychiatric service in an ED in Brazil was the first of its kind. The large percentage of patients referred for hospitalization highlights the importance of specialized psychiatry care for this age group in this facility, which is a common entry point for mental health care.

Blood samples are usually collected daily from different collection points, such hospitals and health centers, and transported to a core laboratory for testing. This paper presents a project to improve the collection routes of two of the largest clinical laboratories in Spain. These routes must be designed in a cost-efficient manner while satisfying two important constraints: (i) two-hour time windows between collection and delivery, and (ii) vehicle capacity. A heuristic method based on a genetic algorithm has been designed to solve the problem of blood sample collection. The user enters the following information for each collection point: postal address, average collecting time, and average demand (in thermal containers). After implementing the algorithm using C programming, this is run and, in few seconds, it obtains optimal (or near-optimal) collection routes that specify the collection sequence for each vehicle. Different scenarios using various types of vehicles have been considered. Unless new collection points are added or problem parameters are changed substantially, routes need to be designed only once. The two laboratories in this study previously planned routes manually for 43 and 74 collection points, respectively. These routes were covered by an external carrier company. With the implementation of this algorithm, the number of routes could be reduced from ten to seven in one laboratory and from twelve to nine in the other, which represents significant annual savings in transportation costs. The algorithm presented can be easily implemented in other laboratories that face this type of problem, and it is particularly interesting and useful as the number of collection points increases. The method designs blood collection routes with reduced costs that meet the time and capacity constraints of the problem.

Epidemiological studies have contributed to the understanding of the total scope of the insomnia problem, both in terms of the incidence of sleep difficulties, and the extent and frequency of hypnotic drug use. Clinical studies - at the Sleep Research and Treatment Center - have been used to evaluate the medical, psychological, pharmacological and situational factors contributing to insomnia, and to evaluate the psychotherapy and chemotherapy best suited to treatment of insomnia. The sleep laboratory studies were of two types: (1) the study of sleep induction, sleep maintenance, and sleep stages, and (2) the use of hypnotic drugs, emphasizing their effectiveness in inducing and maintaining sleep, and the duration of this effectiveness.
The implementation of management systems in accordance with standards like ISO 9001:2008 (1,2) in the clinical laboratories has conferred and added value of reliability and therefore a very significant input to patient safety. As we know the ISO 9001:2008 (1) a certification standard, and ISO 15189:2012 (2) an accreditation standard, both, at the time have generated institutional memory where they have been implemented, the transformation of culture focused on correct execution, control and following, evidence needed and the importance of register.

The present study examined the associations of familial expressed emotion (EE) with clinical and personal recovery among patients with psychiatric disorders, as well as the potential mechanisms underlying these associations. Guided by the content-process theory of self-stigma, we hypothesized that EE would be negatively associated with clinical and personal recovery and that these associations would be mediated by self-stigma content and process. A total of 311 patients with psychiatric disorders completed questionnaires on their perceptions of EE, self-stigma, and recovery. Structural equation modeling demonstrated that EE was positively associated with self-stigma content and process, which were in turn negatively associated with clinical and personal recovery. The indirect effects of EE on clinical and personal recovery, via self-stigma content and process, were also significant. Multigroup analyses further demonstrated that the impact of EE on self-stigma and recovery was generalizable across patients with psychotic and nonpsychotic disorders. Theoretically, our findings revealed the potential pathways through which EE may adversely affect psychiatric recovery. Practically, our findings highlighted the importance of designing multipronged intervention programs to reduce familial EE and its potential harmful impact on psychiatric patients. In addition to helping family members improve their knowledge about psychiatric disorders and adjust their communication styles, practitioners should help psychiatric patients develop resilience against EE, mitigate self-stigma, and achieve recovery.

Leadership and management training during pathology residency have been identified repeatedly by employers as insufficient. A 1-month rotation in clinical laboratory management (CLM) was created for third-year pathology residents. We report on our experience and assess the value of this rotation. The rotation was one-half observational and one-half active. The observational component involved being a member of department and laboratory service line leadership, both at the departmental and institutional level. Observational participation enabled learning of both the content and principles of leadership and management activities. The active half of the rotation was performance of a project intended to advance the strategic trajectory of the department and laboratory service line. In our program that matriculates 4 residents per year, 20 residents participated from April 2010 through December 2015. Their projects either activated a new priority area or helped propel an existing strategic priority forward. Of the 16 resident graduates who had obtained their first employment or a fellowship position, 9 responded to an assessment survey. The majority of respondents (5/9) felt that the rotation significantly contributed to their ability to compete for a fellowship or their first employment position. The top reported benefits of the rotation included people management; communication with staff, departmental, and institutional leadership; and involvement in department and institutional meetings and task groups. Our 5-year experience demonstrates both the successful principles by which the CLM rotation can be established and the high value of this rotation to residency graduates. PMID:28725766

This article aims to reflect on which areas or tasks of microbiology laboratories could be unified with those of clinical biochemistry, hematology, immunology or pathology laboratories to benefit patients and the health system, as well as the areas that should remain independent since their amalgamation would not only fail to provide a benefit but could even jeopardize the quality of microbiological diagnosis, and consequently patient care. To do this, the distinct analytic phases of diagnosis are analyzed, and the advantages and disadvantages of amalgamation are evaluated in each phase. The pros and cons of the unification of certain areas such as the computer system, occupational risk units, customer service, purchasing logistics, and materials storage, etc, are also discussed. Lastly, the effect of unification on urgent microbiology diagnosis is analyzed. Microbiological diagnosis should be unique. The microbiologist should perform an overall evaluation of the distinct techniques used for a particular patient, both those that involve direct diagnosis (staining, culture, antigen detection techniques or molecular techniques) and indirect diagnosis (antibody detection). Moreover, the microbiology laboratory should be independent, with highly trained technicians and specialists in microbiology that provide added value as experts in infection and as key figures in the process of establishing a correct etiological diagnosis.

The use of Reference Change Values (RCV) has been advocated as very useful for monitoring individuals. Most of these are performed for monitoring individuals in acute situations and for following up the improvement or deterioration of chronic diseases. In our study, we aimed at evaluating the RCV calculation for 24 clinical chemistry analytes widely used in clinical laboratories and the utilization of this data. Twenty-four serum samples were analyzed with Abbott kits (Abbott Laboratories, Abbott Park, IL, USA), manufactured for use with the Architect c8000 (Abbott Laboratories, Abbott Park, IL, USA) auto-analyzer. We calculated RCV using the following formula: RCV = Z x 2 1/2x (CVA2 + CVw2)1/2. Four reference change values (RCV) were calculated for each analyte using four statistical probabilities (0.95, and 0.99, unidirectional and bidirectional). Moreover, by providing an interval after identifying upper and lower limits with the Reference Change Factor (RCF), serially measured tests were calculated by using two formulas: exp (Z x 2 1/2 x (CV(A)2 + CVw2)½/100) for RCF(UP) and (1/RCF(UP)) for RCF(DOWN). RCVs of these analytes were calculated as 14.63% for glucose, 29.88% for urea, 17.75% for ALP, 53.39% for CK, 46.98% for CK-MB, 21.00% amylase, 8.00% for total protein, 8.70% for albumin, 51.08% for total bilirubin, 86.34% for direct bilirubin, 6.40% for calcium, 15.03% for creatinine, 21.47% for urate, 14.19% for total cholesterol, 46.62% for triglyceride, 20.51% for HDL-cholesterol, 29.59% for AST, 46.31% for ALT, 31.54% for GGT, 20.92% for LDH, 19.75% for inorganic phosphate, 3.05% for sodium, 11.75% for potassium, 4.44% for chloride (RCV, p laboratories. RCV could be available as a tool for making clinical decision, especially when monitoring individuals.
Full Text Available The aim of this study was to compare clinical and laboratory findings of women with or without uterine leiomyoma.Study group consisted of 82 women with uterine leiomyoma and the control group comprised 42 healthy women. Women’s age, gravity, parity, blood groups, pattern of menstrual cycles, complaints at presentation, fertility, ultrasonographical findings, surgical operations and thyroid function tests were evaluated.There were no significant differences in blood group distribution, gravity, parity and thyroid function test results between the patients and the control subjects (P>0.05. A significant difference was found in the complaints at presentation between two groups (P<0.001. Mentrual cycles irregularity was more frequently found in the patients compared with the controls (57.3% vs. 42.9%, respectively, P=0.009. Although no infertile woman was found in the control group, 8.5% of patients were found to have infertility. The sensitivity of ultrasonography was found to be 97.6%. Except for the existence of higher infertility rate and the menstrual cycles irregularities, no significant difference was found in the clinical and laboratory findings between women with or without uterine leiomyoma. Therefore, physical examination and imaging methods are remained as the most important diagnostic tools for uterine leiomyoma.

The transmission of hepatitis B virus (HBV) in clinical laboratory areas was delineated by the use of hepatitis B surface antigen (HBsAg) as presumptive evidence for the presence of the infective agent. Twenty-six (34%) of 76 environmental surfaces sampled were positive for HBsAg. The outer surfaces of blood- and serum-specimen containers had HBsAg contamination rates of 55% (six of 11) and 44% (four of nine), respectively. Subsequent handling of pipetting aids, marking devices, and other items led to their contamination and further dissemination of HBsAg. An assay instrument for complete determinations of blood cell counts was observed to splatter and drip blood during its operation. The contamination rate for environmental surfaces associated with this instrument was 15%. The data indicate that transmission of HBV in the clinical laboratory is subtle and mainly via hand contact with contaminated items during the various steps of blood processing. These data support the concept that the portal of entry of HBV is through inapparent breaks in skin and mucous membranes.
Full Text Available Background: Thrombocytopenia is an important cause of bleeding. Different clinical conditions associated with thrombocytopenia and their reflections to the hemostatic table will be examined in this study. Methods: A total of 100 patients with thrombocytopenia who were treated in Hacettepe University between 1993 and 2013, 29 with thrombotic thrombocytopenic purpura (TTP, 36 with immune thrombocytopenic purpura (ITP, and 35 with aplastic anemia (AA, were included in the study. Clinical features and laboratory values were reviewed. Results: Thrombosis, fever, and sepsis were more frequently seen in TTP. The most common bleeding type was subcutaneous bleeding in all patient groups. Among patients with TTP, twenty-five patients (86, 2% had fever, 26 patients (89, 7% had a neurologic disorder, and 16 patients (55, 1% had renal dysfunction. Regarding the diagnostic criteria of TTP, 13 patients (44, 8% met five, 12 (41, 4% patients met four and 4 (13, 8% patients met three criteria. The median session of plasmapheresis was 17 (range; 2-127. There was no relation between session count and remission (p=0.28. Conclusion: The severity of clinical presentation and underlying disorders are the most important points with which to approach patients with thrombocytopenia. Clinical reflections may help to identify the cause of thrombocytopenia but not sufficiently demonstrative for diagnosis. [J Contemp Med 2017; 7(4.000: 316-322

Putative occupational stress-related psychiatric disorders are Adjustment Disorders (AD) and Post-Traumatic Stress Disorder (PTSD). Mood Disorders (MD) are not excluded but are unlikely to be identified as occupational diseases. The differential diagnosis between AD and MD is not easy and is based on strict categorical criteria. The aim of this study was to explore differences in personality and mood spectrum symptoms among workers investigated for occupational stress suffering from AD or MD. Sixty-two patients with AD and 43 with MD were recruited and evaluated by means of rating scales for psychosocial occupational risk and work-related stress (WHS, CDL, OSQ), for sleep disturbances (PSQI), for personality disorders (SCID-II) and for mood spectrum symptoms (MOODS-SR). The diagnostic groups did not differ for WHS, OSQ and PSQI scores. The duration of exposure to stressful/adversative work situations was significantly higher in the MD group (p=0.03). Positive family psychiatric history (p=0.005), personality disorders (p=0.009) and pathological personality traits (p<0.0001) were significantly more frequent in the MD group. The MOODS-SR questionnaire total score (p=0.019) and the manic component score (p=0.001) but not the depressive score were significantly higher in the MD group. The present study suggests that positive family psychiatric history, pathological personality traits and spectrum manic symptoms represent markers of vulnerability and low resilience for workers exposed to occupational stress. These characteristics could weaken the etiological relationship between work-related stress and an initial major depressive episode when it is under investigation as a possible occupational disease.

Full Text Available Among numerous viral meningitises from 80% to 90% of cases are accounted for meningitis of enteroviral etiology according to the international data. Despite the favorable disease course, there are forms which are characterized by severe damage of CNS. In order to improve diagnostics of enteroviral meningitis in this article we have made a comparative analysis of clinical and laboratory parameters in 23 patients with enteroviral meningitis and 18 patients with serous meningitis of non-enteroviral etiology. Anamnesis data and the major clinical manifestations of the disease dynamics were analyzed. Particular attention is paid to the comparison of diagnoses, by which patients were sent to infectious hospital, the symptoms that occurred during patients’ admission into hospitals and their severity. The presence and severity of meningeal symptoms and the indices of cerebrospinal fluid in the patients of the comparison group were analyzed in detail. It is shown that enteroviruses are the important factor in the development of meningitis in the children of younger age. The clinical picture of enteroviral meningitis often develops gradually for 2-3 days and includes the typical syndromes: intoxication and meningeal ones. Every third patient with enterovirus infection has diarrhea and catarrhal symptoms, that’s why it is difficult to diagnose meningitis in its early stages, but it allows to assume enteroviral etiology of the disease. The meningitis of enteroviral etiology is characterized by multiple meningeal signs, while the non-enteroviral meningitis is characterized by dissociation with the prevalence of the of Kernig’s and Brudzinski’s symptoms. The analysis of the laboratory data showed that the enteroviral meningitis is characterized by low (over 50-100 cells "mixed" pleocytosis (the ratio of lymphocytes and neutrophils is about 1:1. These data can be used for differential diagnosis between enteroviral meningitis and serous meningitis of

Interest has grown in the use of doll therapy, particularly in geropsychiatric and dementia care settings. In a long-term state psychiatric hospital, a dollhouse-play activity was implemented in an effort to engage an acutely disturbed, middle-aged woman undergoing medication trials and whose symptoms had been refractory to conventional treatments. A schedule of nondirective dollhouse-play activities was implemented over an 8-week period. Measures of behavioral change were tracked. Dramatic clinical improvements were seen, including significant reductions in verbal and physical aggression, use of as-needed medications, and need for close one-to-one monitoring. Improvements were seen prior to achievement of therapeutic drug levels. The patient was successfully discharged from the hospital. Doll play has recently been associated with clinical benefits in the care of patients with dementia and has long been deployed in childhood mental health treatment. The current findings suggest doll play may have applications as a time-limited intervention in the treatment of major psychiatric disorders in adults and warrants consideration when achieving therapeutic alliance has proven particularly challenging.

The application of an agile methodology on analytical systems can provide a line of work that allows the incorporation of planning short work cycles on equips quickly with operational autonomy on the basis of demand and respecting the accreditation requirements and flexibility to ensure adequate performance as the intercomparison of results from the different units analytics, analytical quality and turnaround times. Between 2012 and 2014, a process of analysis and improvement was applied to circuits, a 5 s system, transportation of samples, inventory of reactive and samples, motion of personal and samples, reductions of waiting and delays, overproduction, over processing, and defects of results and reports. At last it seems necessary to apply the Agile methodology to adapt to the evolving necessities in time and the different origins of the samples. It’s have used modular systems where the modules of this study are programmed with immunoassay techniques and it has reduced the operative modules depending on the required activity, ensuring the goals of turnaround times, analytic quality, service, health care continuity, and keeping up with the ISO 15189 accreditation requirements. The results of applying the concept of Lean-Agile to a modular system allows us to reduce the associated costs to the seasonal variation of the health care demand and to adapt the system to the changes on

Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection. Existing treatment options, largely based on

Full Text Available OBJECTIVES: To characterize the clinical, laboratory, and anthropometric profile of a sample of Brazilian patients with glycogen storage disease type I managed at an outpatient referral clinic for inborn errors of metabolism. METHODS: This was a cross-sectional outpatient study based on a convenience sampling strategy. Data on diagnosis, management, anthropometric parameters, and follow-up were assessed. RESULTS: Twenty-one patients were included (median age 10 years, range 1-25 years, all using uncooked cornstarch therapy. Median age at diagnosis was 7 months (range, 1-132 months, and 19 patients underwent liver biopsy for diagnostic confirmation. Overweight, short stature, hepatomegaly, and liver nodules were present in 16 of 21, four of 21, nine of 14, and three of 14 patients, respectively. A correlation was found between height-for-age and BMI-for-age Z-scores (r = 0.561; p = 0.008. CONCLUSIONS: Diagnosis of glycogen storage disease type I is delayed in Brazil. Most patients undergo liver biopsy for diagnostic confirmation, even though the combination of a characteristic clinical presentation and molecular methods can provide a definitive diagnosis in a less invasive manner. Obesity is a side effect of cornstarch therapy, and appears to be associated with growth in these patients.

To asses the accuracy achieved by the A.C.A.T. and other clinical and laboratorial criterion in the diagnoses of T.A.I.B. we investigated twenty patients with goiter and antimicrossomal antibodies titres of 1/1.600 or more. Analysing the parameters useful in the diagnosis, we found a significant correlation between the antimicrossomal antibodies titres and the basal TSH concentration, an elevated basal TSH and an exaggerated response to TRH independent of the patient clinical status reflecting in the majority of the cases a state of subclinical hypotyroidism; an irregular appearance of the radioisotope thyroid scan and a positive response to a perchlorate discharge test. We conclude that from the parameters useful in the T.A.I.B. diagnosis, the A.C.A.T. detection mainly the antimicrossomal antibodies, is an excellent tool to detect patients with a clinical suspect of thyroid auto-immune disease and when we found high tires in a patient with goiter and an elevated basal TSH concentration we can suggest T.A.I.B. diagnosis.

To review academic dismissals, students' rights in dismissal cases, and several key cases involving academic and disciplinary dismissals. Recent academic literature and legal precedents. Not applicable. Not applicable. Students involved in dismissals are protected under the principles of constitutional law and/or contract law, depending on whether the institution is public or private. The basis for dismissal from educational programs is either academic or disciplinary in nature. In academic dismissals, a student has failed to meet either the cognitive or the noncognitive academic standards of the program. In disciplinary dismissals, a student has violated the institutional rules governing conduct. Policies that affect progress in the program and the dismissal process should be published and distributed to students, as well as reviewed for consistency with institutional policies. The amount of documentation needed in the defense of a dismissal decision has not been specified, but, in general, more is better. Procedures are suggested as a guide to dismissals in clinical laboratory programs.

A new urinary conduit utilizing pure vitreous carbon has been used successfully in dogs. Pure carbon appears to be inert with respect to urine and urothelium. Lack of urinary salt encrustation on the exposed surface provides a well-functioning urinary conduit for vesical drainage. Twenty-one vesicostomies were performed in dogs. Careful follow-up and histologic studies of removed specimens were done to establish the biocompatibility of pure carbon. All vesicostomies functioned well. A description of the device, protocol, and results of laboratory experimentation are outlined. The surgical procedure is explained in detail. Results encourage the clinical trial of these devices in humans. Indications include patients with neurogenic vesicla dysfunction and those with total urinary incontinence, both of which require permanent indwelling catheters.

Dengue is endemic in more than 100 countries, giving rise to an increased number of deaths in the last five years in the South-East Asian region. We report our findings from a retrospective study of adults admitted with confirmed dengue at our institution. We studied the clinical and laboratory parameters associated with mortality in these patients. Of the 172 hospitalised patients studied, 156 (90.69 %) recovered while 16 (9.3%) died. Univariate analysis showed altered sensorium on presentation, lower haemoglobin and haematocrit levels, higher serum creatinine, higher serum transaminase and lower serum albumin levels to be significantly associated with mortality in dengue. Further, using stepwise multivariate logistic regression, altered sensorium ( P = 0.006) and hypoalbuminemia ( P = 0.013) were identified as independent predictors of mortality in dengue. Identification of these parameters early in the course of disease should prompt intensification of treatment in dengue cases.

BACKGROUND: Laboratory-based evidence of coagulopathy (LC) is observed in 25-35% of trauma patients, but clinically-evident coagulopathy (CC) is not well described. METHODS: Prospective observational study of adult trauma patients transported by helicopter from the scene to nine Level 1 trauma...... centers in 2015. Patients meeting predefined highest-risk criteria were divided into CC+ (predefined as surgeon-confirmed bleeding from uninjured sites or injured sites not controllable by sutures) or CC-. We used a mixed-effects, Poisson regression with robust error variance to test the hypothesis...... that abnormalities on rapid thrombelastography (r-TEG) and international normalized ratio (INR) were independently associated with CC+. RESULTS: Of 1,019 highest-risk patients, CC+ (n=41, 4%) were more severely injured (median ISS 32 vs 17), had evidence of LC on r-TEG and INR, received more transfused blood...

Objective To identify the prevalence of pyelonephritis during pregnancy and to analyze the clinical and laboratorial aspects, perinatal results and complications. Methods A transversal study of 203 pregnant women who had pyelonephritis during pregnancy and whose labor took place between 2010 and 2016 at a hospital in the state of Santa Catarina, Brazil. The analysis was based on medical records as well as on the hospital's database. Clinical and laboratory conditions, antibiotics, bacterial resistance, perinatal outcomes and complications were all taken into account. The data was compared using the Mann-Whitney test and the Chi-square test. Results A prevalence of 1.97% with pyelonephritis was evidenced, with most patients having it during the second trimester of gestation. The bacteria most commonly found in the urine cultures was Escherichia coli , in 76.6% of cases, followed by Klebsiella pneumoniae (8.7%). Ceftriaxone had the lowest bacterial resistance (only 3.5% of the cases). On the other hand, ampicillin and cephalothin presented higher bacterial resistance, 52% and 36.2%, respectively. The risk of very premature delivery was more than 50% higher in patients with pyelonephritis. Conclusion Ampicillin and first-generation cephalosporins are associated with a higher bacterial resistance while ceftriaxone proved to have a high efficacy for the treatment of pyelonephritis due to low bacterial resistance. Patients with pyelonephritis showed a higher risk for very premature delivery (< 32 weeks). In this casuistry, there were no others significant differences in the overall perinatal outcomes when compared with the routine service series.

Accurate antimicrobial susceptibility testing is vital for patient care and surveillance of emerging antimicrobial resistance. The National Committee for Clinical Laboratory Standards (NCCLS) outlines generally agreed upon guidelines for reliable and reproducible results. In January 1997 we surveyed 320 laboratories participating in the New York State Clinical Evaluation Program for General Bacteriology proficiency testing. Our survey addressed compliance with NCCLS susceptibility testing guidelines for bacterial species designated a problem (Staphylococcus aureus and Enterococcus species) or fastidious (Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria gonorrhoeae) organism. Specifically, we assessed compliance with guidelines for inoculum preparation, medium choice, number of disks per plate, and incubation conditions for disk diffusion tests. We also included length of incubation for S. aureus and Enterococcus species. We found overall compliance with the five characteristics listed above in 80 of 153 responding laboratories (50.6%) for S. aureus and 72 of 151 (47.7%) laboratories for Enterococcus species. The most common problem was an incubation time shortened to less than 24 h. Overall compliance with the first four characteristics was reported by 92 of 221 (41.6%) laboratories for S. pneumoniae, 49 of 163 (30.1%) laboratories for H. influenzae, and 11 of 77 (14.3%) laboratories for N. gonorrhoeae. Laboratories varied from NCCLS guidelines by placing an excess number of disks per plate. Laboratories also reported using alternative media for Enterococcus species, N. gonorrhoeae, and H. influenzae. This study demonstrates a need for education among clinical laboratories to increase compliance with NCCLS guidelines. PMID:10970381
Since ISO 15189:2003 was published, the accreditation program of clinical laboratories based on ISO 15189 has been introduced in many countries, except for those in USA where all clinical laboratories must be required to follow the federal law, CLIA'88. It will certainly help the accredited clinical laboratories improve their quality and competence. In relation to the activity of JCTLM, reference measurement laboratories will be accredited, based on ISO 15195 which is now under its review and amendment by ISO/TC212/WG2. In Japan, JCCLS (Japanese Committee for Clinical Laboratory Standards) and JAB (Japan Accreditation Board for Conformity Assessment) cojointly started the accreditation program for clinical laboratories, based on ISO 15189:2003, and a total of 15 laboratories including university hospitals, community hospitals and independent clinical laboratories have been accredited up until the end of 2006.

Full Text Available AbstractWe were interested in investigating the effects of dance movement therapy (DMT in a psychiatric outpatient clinic with patients diagnosed with depression. DMT aims to engage the patients in physical and verbal exploration of their experiences generated in movement based interaction. The assumption was that DMT, which includes both physical engagement as well as emotional and social exploration, would alleviate the mood and psychiatric symptoms.All adult patients (n = 33 included in the study received treatment as usual (TAU. 21 patients participated in a 12-session DMT group intervention, and the remaining 12 patients chose to take TAU only. The majority of the patients suffered from moderate or severe depression, recurrent and/or chronic type. The effects of the interventions were investigated after the intervention, and at 3-month follow-up. Compared to the TAU, adding DMT seemed to improve the effect of the treatment. The effect of the DMT was observable whether the patient was taking antidepressant medication or not. At follow-up, between group effect sizes (ES were medium in favor for the DMT group (d= 0.60-0.79. In the DMT group, the within ES at the 3 months follow-up varied from 0.62 to 0.82 as compared to TAU 0.15 – 0.37. The results indicated that DMT is beneficial in the treatment of depressed patients.

With the advent of post-genomic era, new technologies create extraordinary possibilities for diagnostics and personalized therapy, transforming todays' medicine. Rooted in both medical genetics and clinical psychiatry, the paper is designed as an integrated source of information of the current and potential future application of emerging genomic technologies as diagnostic tools in psychiatry, moving beyond the classical concept of patient approach. Selected approaches are presented, starting from currently used technologies (next-generation sequencing (NGS) and microarrays), followed by newer options (reverse phenotyping). Next, we describe an old concept in a new light (endophenotypes), subsequently coming up with a sophisticated and complex approach (gene networks) ending by a nascent field (computational psychiatry). The challenges and barriers that exist to translate genomic research to real-world patient assessment are further discussed. We emphasize the view that only a paradigm shift can bring a fundamental change in psychiatric practice, allowing to disentangle the intricacies of mental diseases. All the diagnostic methods, as described, are directed at uncovering the integrity of the system including many types of relations within a complex structure. The integrative system approach offers new opportunity to connect genetic background with specific diseases entities, or concurrently, with symptoms regardless of a diagnosis. To advance the field, we propose concerted cross-disciplinary effort to provide a diagnostic platform operating at the general level of genetic pathogenesis of complex-trait psychiatric disorders rather than at the individual level of a specific disease.

In-house software development for use in a clinical laboratory is a controversial issue. Many of the objections raised are based on outdated software development practices, an exaggeration of the risks involved, and an underestimation of the benefits that can be realized. Buy versus build analyses typically do not consider total costs of ownership, and unfortunately decisions are often made by people who are not directly affected by the workflow obstacles or benefits that result from those decisions. We have been developing custom software for clinical use for over a decade, and this article presents our perspective on this practice. A complete analysis of the decision to develop or purchase must ultimately examine how the end result will mesh with the departmental workflow, and custom-developed solutions typically can have the greater positive impact on efficiency and productivity, substantially altering the decision balance sheet. Involving the end-users in preparation of the functional specifications is crucial to the success of the process. A large development team is not needed, and even a single programmer can develop significant solutions. Many of the risks associated with custom development can be mitigated by a well-structured development process, use of open-source tools, and embracing an agile development philosophy. In-house solutions have the significant advantage of being adaptable to changing departmental needs, contributing to efficient and higher quality patient care.

The only significant advances in blood-taking in 25 years have been the disposable needle and evacuated blood-drawing tube. With the exception of a few isolated barcode experiments, most sample-tracking is performed through handwritten or computer-printed labels. Attempts to reduce the hazards of centrifugation have resulted in air-tight lids or chambers, the use of which is time-consuming and cumbersome. Most commonly used clinical analyzers require serum or plasma, distributed into specialized containers, unique to that analyzer. Aliquots for different tests are prepared by handpouring or pipetting. Moderate to large clinical laboratories perform so many different tests that even multi-analyzers performing multiple analyses on a single sample may account for only a portion of all tests ordered for a patient. Thus several aliquots of each specimen are usually required. We have developed a proprietary serial centrifuge and blood-collection tube suitable for incorporation into an automated or robotic sample-handling system. The system we propose is (a) safe--avoids or prevents biological danger to the many "handlers" of blood; (b) small--minimizes the amount of sample taken and space required to adapt to the needs of satellite and mobile testing, and direct interfacing with analyzers; (c) serial--permits each sample to be treated according to its own "merits," optimizes throughput, and facilitates flexible automation; and (d) smart--ensures quality results through monitoring and intelligent control of patient identification, sample characteristics, and separation process.

To conduct a situational analysis of patient safety culture in public laboratories in the Spanish National Health System and to determine the clinical governance variables that most strongly influence patient safety. A descriptive cross-sectional study was carried out, in which a Survey of Patient Safety in Clinical Laboratories was addressed to workers in 26 participating laboratories. In this survey, which consisted of 45 items grouped into 6 areas, scores were assigned on a scale from 0 to 100 (where 0 is the lowest perception of patient safety). Laboratory managers were asked specific questions about quality management systems and technology. The mean scores for the 26 participating hospitals were evaluated, and the following results observed: in 4of the 6areas, the mean score was higher than 70 points. In the third area (equipment and resources) and the fourth area (working conditions), the scores were lower than 60 points. Every hospital had a digital medical record system. This 100% level of provision was followed by that of an electronic request management system, which was implemented in 82.6% of the hospitals. The results obtained show that the culture of security is homogeneous and of high quality in health service laboratories, probably due to the steady improvement observed. However, in terms of clinical governance, there is still some way to go, as shown by the presence of weaknesses in crucial dimensions of safety culture, together with variable levels of implementation of fail-safe technologies and quality management systems.

[Laboratory medicine in the obligatory postgraduate clinical training system--common clinical training program in the department of laboratory medicine in our prefectural medical university hospital].
I propose a postgraduate common clinical training program to be provided by the department of laboratory medicine in our prefectural medical university hospital. The program has three purposes: first, mastering basic laboratory tests; second, developing the skills necessary to accurately interpret laboratory data; third, learning specific techniques in the field of laboratory medicine. For the first purpose, it is important that medical trainees perform testing of their own patients at bedside or in the central clinical laboratory. When testing at the central clinical laboratory, instruction by expert laboratory technicians is helpful. The teaching doctors in the department of laboratory medicine are asked to advise the trainees on the interpretation of data. Consultation will be received via interview or e-mail. In addition, the trainees can participate in various conferences, seminars, and meetings held at the central clinical laboratory. Finally, in order to learn specific techniques in the field of laboratory medicine, several special courses lasting a few months will be prepared. I think this program should be closely linked to the training program in internal medicine.

Despite growing interest in mobile mental health and utilization of smartphone technology to monitor psychiatric symptoms, there remains a lack of knowledge both regarding patient ownership of smartphones and their interest in using such to monitor their mental health. To provide data on psychiatric outpatients' prevalence of smartphone ownership and interest in using their smartphones to run applications to monitor their mental health. We surveyed 320 psychiatric outpatients from four clinics around the United States in order to capture a geographically and socioeconomically diverse patient population. These comprised a state clinic in Massachusetts (n=108), a county clinic in California (n=56), a hybrid public and private clinic in Louisiana (n=50), and a private/university clinic in Wisconsin (n=106). Smartphone ownership and interest in utilizing such to monitor mental health varied by both clinic type and age with overall ownership of 62.5% (200/320), which is slightly higher than the average United States' rate of ownership of 58% in January 2014. Overall patient interest in utilizing smartphones to monitor symptoms was 70.6% (226/320). These results suggest that psychiatric outpatients are interested in using their smartphones to monitor their mental health and own the smartphones capable of running mental healthcare related mobile applications.

Full Text Available Toxocarosis is a widespread zoonosis caused by the ascarid nematodes Toxocara canis and Toxocara cati, which primarily infect dogs and cats, respectively. Most human infections with Toxocara are asymptomatic; however, some infected individuals may develop a serious illness and even death. Nevertheless, epidemiological knowledge regarding the prevalence and risks associated with Toxocara infection is limited in China. Therefore, we performed a cross-sectional pilot study and estimated the seroprevalence of Toxocara infection in humans in Shandong Province, eastern China for the first time, from June 2011 to July 2013, involving clinically healthy individuals, pregnant women and psychiatric patients, aiming to attract public attention to Toxocara infection.Seroprevalence of Toxocara was determined using an enzyme-linked immunosorbent assay based on a cross-sectional study conducted in Qingdao and Weihai, Shandong Province, eastern China. Factors potentially associated with Toxocara infection were identified by logistic regression analysis. The overall Toxocara seroprevalence among the study population (n = 2866 was 12.25%, and a significantly higher seroprevalence in psychiatric patients (16.40%, 73/445 than that in clinically healthy individuals (13.07%, 187/1431 and pregnant women (9.19%, 91/990 was revealed. Univariate analyses suggested that keeping dogs at home (OR = 0.06, 95% CI 0.05-0.08, P<0.001, contact with cats and dogs (OR = 0.42, 95% CI 0.33-0.53, P<0.001 and exposure with soil (OR = 0.37, 95% CI 0.28-0.49, P<0.001 were risk factors associated with Toxocara infection.The present study revealed, for the first time, that human infection with Toxocara is common in eastern China, posing a significant public health concern. Increasing human and dog populations, population movements and climate change all will serve to increase the importance of this zoonosis. Further studies under controlled conditions are necessary to define potential

Ensuring quality has become a daily requirement in laboratories. In haemostasis, even more than in other disciplines of biology, quality is determined by a pre-analytical step that encompasses all procedures, starting with the formulation of the medical question, and includes patient preparation, sample collection, handling, transportation, processing, and storage until time of analysis. This step, based on a variety of manual activities, is the most vulnerable part of the total testing process and is a major component of the reliability and validity of results in haemostasis and constitutes the most important source of erroneous or un-interpretable results. Pre-analytical errors may occur throughout the testing process and arise from unsuitable, inappropriate or wrongly handled procedures. Problems may arise during the collection of blood specimens such as misidentification of the sample, use of inadequate devices or needles, incorrect order of draw, prolonged tourniquet placing, unsuccessful attempts to locate the vein, incorrect use of additive tubes, collection of unsuitable samples for quality or quantity, inappropriate mixing of a sample, etc. Some factors can alter the result of a sample constituent after collection during transportation, preparation and storage. Laboratory errors can often have serious adverse consequences. Lack of standardized procedures for sample collection accounts for most of the errors encountered within the total testing process. They can also have clinical consequences as well as a significant impact on patient care, especially those related to specialized tests as these are often considered as "diagnostic". Controlling pre-analytical variables is critical since this has a direct influence on the quality of results and on their clinical reliability. The accurate standardization of the pre-analytical phase is of pivotal importance for achieving reliable results of coagulation tests and should reduce the side effects of the influence

This pilot study aims to ascertain the prevalence of self-reported premenstrual, perinatal, and perimenopausal influences on mental health, and of gynecologic conditions that could interact with psychiatric conditions, among women veterans receiving psychiatric care within a Veterans Administration (VA) Women's Health Clinic (WHC). Participants included all women veterans (N=68) who received psychiatric evaluations within a VA WHC over a 5-month period. This setting encompasses colocated and coordinated primary care, gynecologic and mental health services. Evaluations included a Women's Mental Health Questionnaire, a psychiatric interview, and medical record review. Deidentified data were extracted from a clinical data repository for this descriptive study. High proportions of study participants reported that their emotional problems intensified premenstrually (42.6%), during pregnancy (33.3%), in the postpartum period (33.3%), or during perimenopause (18.2%). Unintended pregnancy (70.0% of pregnancies) and pregnancy loss (63.5% of women who had been pregnant) were prominent sex-linked stressors. Dyspareunia (22.1% of participants) and pelvic pain (17.6% of participants) were frequent comorbidities. Among women veterans receiving psychiatric care within a VA WHC, there are high rates of self-reported premenstrual, perinatal, and perimenopausal influences on mental health. This population also has substantial comorbidity of psychiatric disorders with dyspareunia and pelvic pain. This underscores the importance of recognizing and addressing women veterans' sex-specific care needs, including interactions among reproductive cycle phases, gynecologic pain, and psychiatric symptoms. The findings support the need for greater awareness of the sex-specific mental health needs of women veterans, and for more definitive studies to further characterize these needs.
The cost, speed, and quality are the three important factors recently indicated by the Ministry of Health, Labour and Welfare (MHLW) for the purpose of accelerating clinical studies. Based on this background, the importance of laboratory tests is increasing, especially in the evaluation of clinical study participants' entry and safety, and drug efficacy. To assure the quality of laboratory tests, providing high-quality laboratory tests is mandatory. For providing adequate quality assurance in laboratory tests, quality control in the three fields of pre-analytical, analytical, and post-analytical processes is extremely important. There are, however, no detailed written requirements concerning specimen collection, handling, preparation, storage, and shipping. Most laboratory tests for clinical studies are performed onsite in a local laboratory; however, a part of laboratory tests is done in offsite central laboratories after specimen shipping. As factors affecting laboratory tests, individual and inter-individual variations are well-known. Besides these factors, standardizing the factors of specimen collection, handling, preparation, storage, and shipping, may improve and maintain the high quality of clinical studies in general. Furthermore, the analytical method, units, and reference interval are also important factors. It is concluded that, to overcome the problems derived from pre-analytical processes, it is necessary to standardize specimen handling in a broad sense.

A lot of researches have proven that health education can help patients to maintain and improve their health. And it also shortens the time staying in hospital to save medication resource. Because the patients are willing to get healthcare knowledge to enhance the ability of self-care, they pay more attention to the health education. In Taiwan, the clinical nurses play an important role in patient education, and the health education take most time in their daily work. Such work includes the collection, production and delivery of education materials. To generate the correct and customized health education material is the key of success of patient education. In this study, we established a computer-aided health education contents generating system for psychiatric patients by integrating the databases for disease, medicine and nursing knowledge to assist nurse generating the customized health education document suitable for different patients. This system was evaluated by clinical nurses in usability and feasibility. This system is helpful for nurse to carry out the clinical health education to patients and further to encourage patient to pay attention to self-health.

Full Text Available Loxapine is a first generation antipsychotic, belonging to the dibenzoxazepine class. Recently, loxapine has been reformulated at a lower dose, producing an inhaled powder that can be directly administered to the lungs to treat the agitation associated with psychiatric disorders, such as schizophrenia and bipolar disorder. Thus, the aim of this narrative and clinical mini-review was to evaluate the efficacy and tolerability of inhaled loxapine in the treatment of acute agitation in patients with psychiatric disorders. The efficacy of inhaled loxapine has been evaluated in one Phase II trial on patients with schizophrenia, and in two Phase III trials in patients with schizophrenia and bipolar disorder. Moreover, there are two published case series on patients with borderline personality disorder and dual diagnosis patients. Inhaled loxapine has proven to be effective and generally well tolerated when administered to agitated patients with schizophrenia and bipolar disorder. Two case series have suggested that inhaled loxapine may also be useful to treat agitation in patients with borderline personality disorder and with dual diagnosis, but further studies are needed to clarify this point. However, the administration of inhaled loxapine requires at least some kind of patient collaboration, and is not recommended in the treatment of severe agitation in totally uncooperative patients. Moreover, the drug-related risk of bronchospasm must always be kept in mind when planning to use inhaled loxapine, leading to a careful patient assessment prior to, and after, administration. Also, the higher costs of inhaled loxapine, when compared to oral and intramuscular medications, should be taken into account when selecting it for the treatment of agitation.

The interplay between the workflow for clinical tasks and research data collection is often overlooked, ultimately making it ineffective. To the best of our knowledge, no previous studies have developed standards that allow for the comparison of workflow models derived from clinical and research tasks toward the improvement of data collection processes. In this study we used the term dissonance for the occurrences where there was a discord between clinical and research workflows. We developed workflow models for a translational research study in psychiatry and the clinic where its data collection was carried out. After identifying points of dissonance between clinical and research models we derived a corresponding classification system that ultimately enabled us to re-engineer the data collection workflow. We considered (1) the number of patients approached for enrollment and (2) the number of patients enrolled in the study as indicators of efficiency in research workflow. We also recorded the number of dissonances before and after the workflow modification. We identified 22 episodes of dissonance across 6 dissonance categories: actor, communication, information, artifact, time, and space. We were able to eliminate 18 episodes of dissonance and increase the number of patients approached and enrolled in research study trough workflow modification. The classification developed in this study is useful for guiding the identification of dissonances and reveal modifications required to align the workflow of data collection and the clinical setting. The methodology described in this study can be used by researchers to standardize data collection process.

Virtually all the general practices in Norway participate in the Norwegian Quality Improvement of Laboratory Services in Primary Care, NOKLUS. In order to assess and develop NOKLUS's services, it was decided to carry out an investigation in the largest participating group, general practices. In autumn 2008 a questionnaire was sent to all Norwegian general practices asking for feedback on different aspects of NOKLUS's main services: contact with medical laboratory technologists, sending of control materials, use and maintenance of practice-specific laboratory binders, courses, and testing of laboratory equipment. In addition, attitudes were elicited towards possible new services directed at assessing other technical equipment and clinical use of tests. Responses were received from 1290 of 1552 practices (83%). The great majority thought that the frequency of sending out control material should continue as at present, and they were pleased with the feedback reports and follow-up by the laboratory technologists in the counties. Even after many years of practical experience, there is still a need to update laboratory knowledge through visits to practices, courses, and written information. Practices also wanted quality assurance of blood pressure meters and spirometers, and many doctors wanted feedback on their use of laboratory tests. Services regarding quality assurance of point-of-care tests, guidance, and courses should be continued. Quality assurance of other technical equipment and of the doctor's clinical use of laboratory tests should be established as part of comprehensive quality assurance.

Measurement-based care refers to the use of standardized scales to measure the outcome of psychiatric treatment. Diagnostic heterogeneity poses a challenge toward the adoption of a measurement-based care approach toward outcome evaluation in clinical practice. In the present article, we propose adopting the concept of psychiatric vital signs to facilitate measurement-based care. Medical vital signs are measures of basic physiologic functions that are routinely determined in medical settings. Vital signs are often a primary outcome measure, and they are also often adjunctive measurements. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services project, we examined the frequency of depression and anxiety in a diagnostically heterogeneous group of psychiatric outpatients to determine the appropriateness of considering their measurement as psychiatric vital signs. Three thousand psychiatric outpatients were interviewed with the Structured Clinical Interview for DSM-IV supplemented with items from the Schedule for Affective Disorders and Schizophrenia. We determined the frequency of depression and anxiety evaluated according to the Schedule for Affective Disorders and Schizophrenia items. In the entire sample of 3000 patients, 79.3% (n = 2378) reported clinically significant depression of at least mild severity, 64.4% (n = 1932) reported anxiety of at least mild severity, and 87.4% (n = 2621) reported either anxiety or depression. In all 10 diagnostic categories examined, most patients had clinically significant anxiety or depression of at least mild severity. These findings support the routine assessment of anxiety and depression in clinical practice because almost all patients will have these problems as part of their initial presentation. Even for those patients without depression or anxiety, the case could be made that the measurement of depression and anxiety is relevant and analogous to measuring certain physiologic

To describe the prevalence, demographic and clinical characteristics of body dysmorphic disorder (BDD) compared with other psychiatric outpatients with a mood, anxiety or somatoform disorder. Outpatients referred for treatment of a mood, anxiety or somatoform disorder were routinely assessed at intake. A structured interview (MINI-Plus), observer-based and self-rating instruments were administered by an independent assessor. Among our sample of 3798 referred patients, 2947 patients were diagnosed with at least one DSM-IV mood, anxiety or somatoform disorder. Of these patients 1.8% (n = 54) met the diagnostic criteria for BDD. In comparison with other outpatients, patients with BDD were on average younger, less often married and were more often living alone. Highly prevalent comorbid diagnoses were major depression (in 46.3% of cases), social anxiety disorder (in 35.2% of cases) and obsessive-compulsive disorder (OCD) (in 16.7% of cases). Furthermore, patients with BDD had higher scores on the Clinical Global Impression of Severity (CGI-S) as well as lower scores on the Short Form 36 social role functioning. BDD is frequently associated with depression, social phobia and OCD. Patients with BDD have more distress and more impaired interpersonal functioning.

To promote clinical application of the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) system a shorter version (the mini-SCAN) was devised. Its psychometric properties were unknown. To establish the validity and practical properties of the mini-SCAN. One hundred and six participants were interviewed twice, once with the SCAN and once with the mini-SCAN. The level of agreement was established for the categories: no disorder, affective disorders, anxiety disorders, non-affective psychotic disorders, affective psychotic disorders. The mini-SCAN is a valid instrument. Most kappa values were around 0.90. Only for the class of affective psychotic disorders was the agreement moderate. Mean duration of the mini-SCAN interviews was 25 min shorter than the SCAN interviews. Participants and interviewers were generally satisfied with the interview format and questions. The mini-SCAN can be used as a diagnostic instrument for clinical purposes and for clinical studies when the present episode is the focus of attention.

Given the importance of evidence-based guidelines in health care, we surveyed the laboratory hematology community to determine their opinions on guideline development and their experience and interest in developing clinical hematology laboratory practice guidelines. The study was conducted using an online survey, distributed to members of the International Society for Laboratory Hematology (ISLH) in 2015, with analysis of collected, anonymized responses. A total of 245 individuals participated. Most worked in clinical and/or research laboratories (83%) or industry (11%). 42% felt there were gaps in current guidelines. The majority (58%) recommended that ISLH engages its membership in guideline development. Participants differed in their familiarity with, and use of, different organizations' guidelines. Participants felt it was important to follow best practice recommendations on guideline development, including engagement of experts, statement about conflict of interests and how they were managed, systematic review and grading evidence for recommendations, identifying recommendations lacking evidence or consensus, and public input and peer review of the guideline. Moreover, it was considered important to provide guidelines free of charge. Industry involvement in guidelines was considered less important. The clinical laboratory hematology community has high expectations of laboratory practice guidelines that are consistent with recent recommendations on evidence-based guideline development. © 2016 John Wiley & Sons Ltd.

Full Text Available Objective: Rapid cycling (RC is a feature of bipolar disorder (BD that has been associated with worse outcome and more severe disability. Our goal was to investigate the association of demographic and clinical factors with RC. Methods: We compared RC and non-rapid cycling (NRC BD patients from the Brazilian Research Network in Bipolar Disorder (BRN-BD regarding age at onset of BD; total number of episodes; previous number of manic, depressive, mixed, and hypomanic episodes; polarity of the first episode; gender; number of suicide attempts; number of lifetime hospitalizations and lifetime history of at least one hospitalization; family history of mood disorder; clinical comorbidities such as hypothyroidism, hyperthyroidism, seizures; and current use of medications such as lithium, anticonvulsants, antipsychotics, and antidepressants. Results: We studied 577 patients and found that 100 (17.3% met the criteria for RC in the year before the investigation. RC patients had earlier age at onset, longer duration of disease, more lifetime depressive and manic episodes, higher number of suicide attempts, and higher rate antidepressant use. Conclusion: The presence of RC in the previous year was associated with specific clinical characteristics closely related to worse outcome in the course of BD.
Full Text Available Background: Cotard’s Syndrome (CS is a rare and severe neuropsychiatric condition in which the central feature is the existence of nihilistic delusions. Controversy has ensued about the precise clinical picture Jules Cotard meant to describe and attempts have been made, more recently, not only to clarify the terminology, but also to define different types of this syndrome and explore its biological basis. Aims: We intend to briefly review the terminology, etiology, epidemiology and differential diagnosis of this syndrome, based on two clinical cases. Methods: Bibliographic search conducted through the electronic databases Medline and Gallica (French National Library, consultation of clinical records and direct interviews with the patients. Results and Conclusions: Typically the patients diagnosed with CS manifest the delusional idea that they are dying or already dead. However, it is also possible that they deny the existence of only some parts of their own body, or the functioning of some organs, and they may even sometimes deny the existence of the external world. We illustrate the case of a 66-year-old woman, diagnosed with bipolar affective disorder, admitted in the context of a severe depressive episode with psychotic symptoms, compatible with CS type II and the case of a young male aged 22, admitted due to a first psychotic episode with schizophrenia like characteristics, presenting with nihilistic delusions compatible with CS type I.
Full Text Available The main objective of drug delivery systems is to deliver a drug effectively, specifically to the site of action and to achieve greater efficacy and minimise the toxic effects compared to conventional drugs. Amongst various carrier systems, liposomes have generated a great interest because of their versatility. Liposomes are vesicular concentric bilayered structures, which are biocompatible, biodegradable and nonimmumnogenic. They can control the delivery of drugs by targeting the drug to the site of action or by site avoidance drug delivery or by prolonged circulation of drugs. Amphotericin B (Amp B remains the drug of choice in most systemic mycoses and also as a second line treatment for Kala azar. However, its toxic effects often limit its use. Although the liposome delivery system has been tried for several drugs, only a few have been used in patients due to the slow development of necessary large-scale pharmaceutical procedures. This paper reviews the development of the technique for liposomal Amphotericin B (L-Amp-LRC-1, FungisomeTM drug delivery system in our laboratory in collaboration with the department of Biochemistry, Delhi University in India and proving the safety and efficacy of this preparation in clinical practice. It also attempts to compare the efficacy and benefits of our product for Indian patients with those of similar products and it includes facts from the publications that flowed from our work. As compared to conventional Amp B, Fungisome is infused over a much shorter period requiring a smaller volume and no premedication. It was found to be safe in patients who had developed serious unacceptable toxicity with conventional Amp B. In renal transplant patients, Fungisome did not produce any nephrotoxicity. Fungisome is effective in fungal infections resistant to fluconazole, conventional Amp B and in virgin and resistant cases of visceral leishmaniasis. The cost of any drug is of great significance, especially in India

In the present study, the usefulness of chromogenic medium, slide culture technique and Vitek2 Compact (V2C has been analysed. A total of 173 clinical isolates of yeast species were included in the study. An algorithm to identify such isolates in routine clinical microbiology laboratory was prepared and followed. Chromogenic medium was able to identify Candida albicans, C. tropicalis, C. krusei, C. parapsilosis and Trichosporon asahii. Chromogenic medium was also helpful in identifying "multi-species" yeast infections. The medium was unable to provide presumptive identification of C. pelliculosa, C. utilis, C. rugosa, C. glabrata and C. hemulonii. Vitek 2 compact (V2C differentiated all pseudohypae non-producing yeast species. The algorithm followed was helpful in timely presumptive identification and final diagnosis of yeast infections, including multi-species yeast infections.

The professional duties of the specialists in clinical chemistry differ from country to country in Europe. One of the main goals of the Strategic Plan of the Forum of the European Societies of Clinical Chemistry and Laboratory Medicine (FESCC; IFCC-Europe) is to promote a high scientific and professional standard in the field of clinical chemistry and laboratory medicine in Europe. This can be stimulated by the knowledge of the local conditions in each country and by striving towards a strong and harmonised position in all the European countries. In order to enhance the knowledge of the managerial situation of the specialists in clinical chemistry in Europe, FESCC launched a survey in September 2000. This survey provides information about the position of the specialists in clinical chemistry in the various disciplines in the medical laboratories and in hospitals, and about the advisory tasks and the managerial education during the post-graduate training in clinical chemistry. Of the 35 FESCC member countries 33 have participated in the survey (94%). The results show a rather heterogeneous situation in Europe caused by the local historical developments, the differences in academic background and the relative numbers of private and physicians' office laboratories. Large differences exist between the European countries in the disciplines of laboratory medicine that are headed by a specialist in clinical chemistry. In the different countries the clinical chemistry laboratories are headed by specialists in clinical chemistry in between 20% and 100% of the laboratories. The haematology, immunology, microbiology, therapeutic drug monitoring, molecular biology and haemostasis laboratories and departments of blood banking are headed by specialists in clinical chemistry in between 0% and 100% of the laboratories. The responsibilities for the various managerial tasks of the specialists in clinical chemistry show no uniformity in Europe. In the majority of the countries the

Despite attempts in psychiatry to adopt an integrative biopsychosocial model, social scientists have observed that psychiatrists continue to operate according to a mind-brain dichotomy in ways that are often covert and unacknowledged and suggest that the same intuitive cognitive schemas that people use to make judgments of responsibility lead to dualistic reasoning among clinicians. The goal of this study was to confirm these observations. Self-report questionnaires were sent to the 270 psychiatrists and psychologists in the Department of Psychiatry at McGill University. In response to clinical vignettes, the participants rated the level of intentionality, controllability, responsibility, and blame attributable to the patients, as well as the importance of neurobiological, psychological, and social factors in explaining the patients' symptoms. A total of 136 faculty members (50.4%) responded, and 127 were included in the analysis. Factor analysis revealed a single dimension of responsibility regarding the patients' illnesses that correlated positively with ratings of psychological etiology and negatively with ratings of neurobiological etiology. Psychological and neurobiological ratings were inversely correlated. Multivariate analyses of variance supported these results. Mental health professionals continue to employ a mind-brain dichotomy when reasoning about clinical cases. The more a behavioral problem is seen as originating in "psychological" processes, the more a patient tends to be viewed as responsible and blameworthy for his or her symptoms; conversely, the more behaviors are attributed to neurobiological causes, the less likely patients are to be viewed as responsible and blameworthy.

Full Text Available Advances made in genetic testing and tools applied to pharmacogenetics are increasingly being used to inform clinicians in fields such as oncology, hematology, diabetes (endocrinology, cardiology and expanding into psychiatry by examining the influences of genetics on drug efficacy and metabolism. We present a clinical case example of an adolescent male with anxiety, attention deficit hyperactivity disorder (ADHD and autism spectrum disorder who did not tolerate numerous medications and dosages over several years in attempts to manage his symptoms. Pharmacogenetics testing was performed and DNA results on this individual elucidated the potential pitfalls in medication use because of specific pharmacodynamic and pharmacokinetic differences specifically involving polymorphisms of genes in the cytochrome p450 enzyme system. Future studies and reports are needed to further illustrate and determine the type of individualized medicine approach required to treat individuals based on their specific gene patterns. Growing evidence supports this biological approach for standard of care in psychiatry.

The present article reports on recruiting strategies in a 16-week, multi-site trial of osmotic-release methylphenidate combined with cognitive-behavioral therapy in adolescents with co-occurring attention deficit hyperactivity disorder and substance use disorder. A multifaceted recruiting strategy was employed that targeted multiple referral sources, used incentives, involved numerous staff members, emphasized the therapeutic alliance during prescreening, and utilized data to modify strategies based on results. Overall, 303 adolescents were randomized from 1,333 total referrals across 11 participating sites. Overall, existing treatment program sources, including treatment program staff, social services, the juvenile justice system, and mental health clinics provided a majority of referrals for pre-screening and randomization. These results support the feasibility of recruiting dually-diagnosed adolescents utilizing a multifaceted approach involving the entire study team.

This study was aimed to determine the socio-demographic, clinical and behavioral characteristics associated with suicide attempts in psychiatric outpatients in two public hospitals in Durango, Mexico. Two hundred seventy six psychiatric outpatients (154 suicide attempters and 122 patients without suicide attempt history) attended the two public hospitals in Durango City, Mexico were included in this study. Socio-demographic, clinical and behavioral characteristics were obtained retrospectively from all outpatients and compared in relation to the presence or absence of suicide attempt history. Increased prevalence of suicide attempts was associated with mental and behavioral disorders due to psychoactive substance use (F10-19) (P=0.01), schizophrenia, schizotypal and delusional disorders (F20-29) (P=0.02), mood (affective) disorders (F30-39) (Purban residence (OR=2.31, 95% CI: 1.17-4.57; P=0.01), memory impairment (OR=1.91, 95% CI: 1.07-3.40; P=0.02), alcohol consumption (OR=2.39, 95% CI: 1.21-4.70; P=0.01), and sexual promiscuity (OR=3.90, 95% CI: 1.74-8.77; PMexico. Results may be useful for an optimal planning of preventive measures against suicide attempts in psychiatric outpatients.

Kappa-opioid receptor (KOR) antagonists are currently being considered for the treatment of a variety of neuropsychiatric conditions, including depressive, anxiety, and substance abuse disorders. A general ability to mitigate the effects of stress, which can trigger or exacerbate these conditions, may explain their putative efficacy across such a broad array of conditions. The discovery of their potentially therapeutic effects evolved from preclinical research designed to characterize the molecular mechanisms by which experience causes neuroadaptations in the nucleus accumbens (NAc), a key element of brain reward circuitry. This research established that exposure to drugs of abuse or stress increases the activity of the transcription factor CREB (cAMP response element binding protein) in the NAc, which leads to elevated expression of the opioid peptide dynorphin that in turn causes core signs of depressive- and anxiety-related disorders. Disruption of KORs-the endogenous receptors for dynorphin-produces antidepressant- and anxiolytic-like actions in screening procedures that identify standard drugs of these classes, and reduces stress effects in tests used to study addiction and stress-related disorders. Although interest in this target is high, prototypical KOR antagonists have extraordinarily persistent pharmacodynamic effects that complicate clinical trials. The development of shorter acting KOR antagonists together with more rapid designs for clinical trials may soon provide insight on whether these drugs are efficacious as would be predicted by preclinical work. If successful, KOR antagonists would represent a unique example in psychiatry where the therapeutic mechanism of a drug class is understood before it is shown to be efficacious in humans. © 2016 Wiley Periodicals, Inc.
This commentary will introduce lean concepts into the clinical microbiology laboratory. The practice of lean in the clinical microbiology laboratory can remove waste, increase efficiency, and reduce costs. Lean, Six Sigma, and other such management initiatives are useful tools and can provide dividends but must be accompanied by organizational leadership commitment to sustaining the lean culture in the laboratory setting and providing resources and time to work through the process.

In the last few decades, the State of Israel has become a target for work migrants, refugees, asylum seekers and victims of human trafficking, as part of the trend of world immigration. Immigration is a process of loss and change with significant socio-psychological stress, with possible effects on the immigrants' mental health. The Physicians for Human Rights - Israel (PHR) Association operates a psychiatric clinic as part of the Open Clinic for Work Migrants and Refugees. This article will present major clinical issues regarding psychiatry and immigration in Israel according to the data collected at the clinic. Trauma and stress-related psychopathology was found to have a high prevalence in immigrant patients treated at the clinic; prevalence of PTSD (post-traumatic stress disorder) in immigrants was high (23%) and even higher in refugees (33%). Female immigrants are at higher risk for psychiatric hospitalization. The relative rate of African patients at the clinic is significantly higher than patients from other continents. A significant association was found between psychiatric hospitalization and suicide attempts. Immigrant patients present a combination of psychiatric, socio-economic and general medical conditions, which demands a holistic view of the patient. The evaluation of an immigrant patient must take into account the stress related to immigration, gender, culture of origin and the risk for suicide and hospitalization. Treatment recommendations include awareness of cultural diversities, acquiring information regarding the pre-immigration history, preferably using cultural consultants with background in the immigrants' culture and community. Decision-making about medication and diagnostic evaluation should be as inexpensive as possible. Basic human needs (food, shelter) and family support should be included in the decisions about treatment.

Full Text Available Objectives: Child abuse has been a continuous, hidden health and social problem in all over the world. Identifying risk factors are crucial to implement protective services. In Turkey, data of the legal cases are still lacking. This study aims to assess the sociodemographic and psychiatric features of the sexually abused children who have been referred for forensic evaluation together with their identity issues. Materials and Methods: The forensic files of the sexually abused cases (tı 11: 9 boys, 32 girls who had been referred to the child psychiatry outpatient clinic were evaluated. Psychiatric diagnoses in the files were based on the Schedule for Affective Disorders and Schizophrenia for School-age children- Turkish Version. Data on age, gender, socioeconomic status and diagnoses of the victims and characteristics of the abusers were gathered and analysed by descriptive statistical methods. Results: Mean age of the victims was 11.54±3.31 years. Socioeconomic levels of their families were mostly lower class with rate of 51.2%. All perpetrators were male with a mean age of 23 years (min 14; max 67. When the consanguinity of the abusers and victims were taken into consideration, it was found that they were intrafamilial (fathers and brothers rate:12.2%, close relatives (19.5%, distant relatives (22.0%, other familiar (such as neighbours, friends: 14.6% and unfamiliar (24.4% people for the victims. 19.5% of the victims had mental retardation. The most common diagnoses of the victims were posttraumatic stress disorder (46.3%, other anxiety disorders (17.1%, and major depression (24.4%. Conclusion: Identified risk factors for sexual abuse, determined as the result of this study, are being a female child, late childhood period, mental retardation, and low economic status. The abusers were males who were familiar to the child victims. Preventive measures should be implemented for the entire population, particularly involving the high- risk groups

A modified Hales-Randle method for insulin radioimmunoassay is described. An insulin response curve was established in normal cases after glucose loading. Pathological changes were then investigated in patients and animals before and after therapeutic, operative and radiological procedures. Four representative groups of this material will be illustrated. (1) Psychotic patients (acute and chronic schizophrenics, neurotics and depressives) were examined with the aim of learning about the variable effects produced by insulin shock-therapy, as well as for biochemical diagnosis purposes in psychotics. Highest insulin response curves were found in chronic schizophrenics with improvement after insulin therapy. Schizophrenics without improvement presented different curves. Lowest insulin values were found in acute schizophrenia. Depressives and anxiety neurotics showed insulin tolerance curves similar to those of non-psychotic patients. (2) Pancreatic patients. Special attention was paid to pancreatic carcinoma (insulinoma excepted). In most cases of pancreatic carcinoma a very low and flat insulin tolerance curve was found. The above findings may be of a diagnostic importance in this condition, which is clinically hardly recognized. (3) Liver cirrhotic patients. A special group of shunt operated patients was investigated. The study was performed on eight liver cirrhotics before and after porto-caval or reno-splenal shunt operation. The plasma insulin level was examined in the vena cava, renal and cubital blood. The influence of tolbutamide was analysed. The normally occurring retention of insulin by normal hepatic tissue was found to be considerably disturbed. Other interesting changes were observed. (4) The plasma insulin level in the radiologically exposed. Experimental and clinical studies were performed, with insulin doses before and after radiation. Whole body X-ray exposure (300 rads) to rats resulted in a rapid lowering of insulin or its disappearance. Recovery was

We have no proper reference indicating the quality of clinical laboratory practice, which should clearly illustrates that better medical tests require more expenses. Japanese Society of Laboratory Medicine was concerned about recent difficult medical economy and issued a committee report proposing a guideline to evaluate the good laboratory practice. According to the guideline, we developed software that illustrate a cost-quality balance carried out by clinical laboratory practice. We encountered a number of controversial problems, for example, how to measure and weight each quality-related factor, how to calculate costs of a laboratory test and how to consider characteristics of a clinical laboratory. Consequently we finished only prototype software within the given period and the budget. In this paper, software implementation of the guideline and the above-mentioned problems are summarized. Aiming to stimulate these discussions, the operative software will be put on the Society's homepage for trial

Clinicians have traditionally ordered laboratory tests using paper-based orders and requisitions. However, paper orders are becoming increasingly incompatible with the complexities, challenges, and resource constraints of our modern healthcare systems and are being replaced by electronic order entry systems. Electronic systems that allow direct provider input of diagnostic testing or medication orders into a computer system are known as Computerized Provider Order Entry (CPOE) systems. Adoption of laboratory CPOE systems may offer institutions many benefits, including reduced test turnaround time, improved test utilization, and better adherence to practice guidelines. In this review, we outline the functionality of various CPOE implementations, review the reported benefits, and discuss strategies for using CPOE to improve the test ordering process. Further, we discuss barriers to the implementation of CPOE systems that have prevented their more widespread adoption. PMID:21886891

To assess the correlation of psychosocial resiliency factors (mindfulness and coping) with symptoms of posttraumatic stress, anxiety, and depression in patients recently admitted to the neuroscience ICU and their primary informal caregivers. A descriptive, cross-sectional correlational study. Neuroscience ICU in a major medical center. A total of 78 dyads of patients (total n = 81) and their primary caregivers (total n = 92) from June to December 2015. Study enrollment occurred within the first 2 weeks of patient admission to the neuroscience ICU. None. Dyads completed self-report measures of mindfulness (Cognitive and Affective Mindfulness Scale-Revised), coping (Measure of Coping Status-A), posttraumatic stress (Posttraumatic Checklist-Specific Stressor), anxiety (Hospital Anxiety and Depression Scale-A), and depression (Hospital Anxiety and Depression Scale-D). Rates of clinically significant posttraumatic stress, anxiety, and depressive symptoms were high and comparable between patient and caregiver samples. Own psychological resilience factors and psychiatric symptoms were strongly correlated for both patients and caregivers. Depressive symptoms were interdependent between patients and their caregivers, and one's own mindfulness was independently related to one's partner's depressive symptoms. Rates of clinically significant psychiatric symptoms were high, equally prevalent in patients and caregivers, and interdependent between patients and their caregivers. For both patients and caregivers, psychological resiliency factors were associated with both self and partner psychiatric symptoms. Findings suggest that attending to the psychiatric health of both patients and caregivers in the neuroscience ICU is a priority and that patients and their caregivers must be considered together in a system to fully address either individual's psychiatric symptoms.

This study aims to evaluate the performance of a few biochemistry analysis and make recommendations to the place of the stakeholders. It is a cross-sectional study conducted between the October 1(st), 2012 and the July 31, 2013 bearing on the results of 5 common examinations of clinical biochemistry, provided by 11 laboratories volunteers opening in the public and private sectors. These laboratories have analysed during the 3 cycles, 2 levels (medium and high) of serum concentration of urea, glucose, creatinine and serum aminotransferases. The performance of laboratories have been determined from the acceptable limits corresponding to the limits of total errors, defined by the French Society of Clinical Biology (SFBC). A system of internal quality control is implemented by all laboratories and 45% of them participated in international programs of external quality assessment (EQA). The rate of acceptable results for the entire study was of 69%. There was a significant difference (plaboratories engaged in a quality approach and the group with default implementation of the quality approach. Also a significant difference was observed between the laboratories of the central level and those of the peripheral level of our health system (plaboratories remains relatively unsatisfactory. It is important that the Ministry of Health put in place a national program of EQA with mandatory participation.

Carbapenemases, enzymes that hydrolyze carbapenem-class antimicrobials, pose serious clinical and diagnostic challenges, including their recent rapid spread among members of the Enterobacteriaceae, a family with no inherent carbapenem resistance. Currently there is no one-size-fits-all method for detecting carbapenem-resistant Enterobacteriaceae (CRE) in the laboratory, nor how to differentiate carbapenemase-producers (CP) from isolates that are carbapenem-resistant via other or combined mechanisms. This article reviews definitions for CRE and CP-CRE, and discusses current phenotypic and molecular methods available to the clinical laboratory for the detection of both CP and non-CP CRE. Expert commentary: Routine evaluation of carbapenem resistance mechanism by the routine clinical laboratory are not necessary for patient care, as clinical breakpoints best predict response. However, evaluation for carbapenemase is integral to infection control efforts, and laboratories should have the capacity to do such testing, either in house or by submitting isolates to a reference laboratory.

The LabDirector system has been developed at the Oregon Health Sciences University to support the operation of our clinical DNA analysis laboratory. Through an iterative design process which has spanned two years, we have produced a system that is both highly tailored to a clinical genetics production laboratory and flexible in its implementation, to support the rapid growth and change of protocols and methodologies in use in the field. The administrative aspects of the system are integrated with an enterprise schedule management system. The laboratory side of the system is driven by a protocol modeling and execution system. The close integration between these two aspects of the clinical laboratory facilitates smooth operations, and allows management to accurately measure costs and performance. The entire application has been designed and documented to provide utility to a wide range of clinical laboratory environments.

Although evaluation of biochemical analytes in blood is common in veterinary practice, studies assessing the global quality of veterinary in-clinic and reference laboratory testing have not been reported. The aim of this study was to assess the quality of biochemical testing in veterinary laboratories using results obtained from analyses of 3 levels of assayed quality control materials over 5 days. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index to determine factors contributing to poor performance, and agreement between in-clinic and reference laboratory mean results. The suitability of in-clinic and reference laboratory instruments for statistical quality control was determined using adaptations from the computerized program, EZRules3. Reference laboratories were able to achieve desirable quality requirements more frequently than in-clinic laboratories. Across all 3 materials, > 50% of in-clinic analyzers achieved a sigma metric ≥ 6.0 for measurement of 2 analytes, whereas > 50% of reference laboratory analyzers achieved a sigma metric ≥ 6.0 for measurement of 6 analytes. Expanded uncertainty of measurement and ± total allowable error resulted in the highest mean percentages of analytes demonstrating agreement between in-clinic and reference laboratories. Owing to marked variation in bias and coefficient of variation between analyzers of the same and different types, the percentages of analytes suitable for statistical quality control varied widely. These findings reflect the current state-of-the-art with regard to in-clinic and reference laboratory analyzer performance and provide a baseline for future evaluations of the quality of veterinary laboratory testing. © 2012 American Society for Veterinary Clinical Pathology.

In the late 90's there was a change in both the route of transmission and the people at risk for sporotrichosis. This zoonotic cat-man alternative transmission route elicited changes in strategies to control the epidemic. There was a progressive increase in the number of cases involving especially children and the elderly. In addition to becoming hyperendemic, uncommon clinical pictures like immunoreactive clinical presentations or severe systemic cases have emerged. New species were identified and classified through molecular tools using more virulent clinical isolates, like S. brasiliensis, compared to the environmental isolates. Likewise, different species of Sporothrix have been associated with different geographic regions. The serological and molecular techniques are used as an auxiliary tool for the diagnosis and/or for species identification, although the isolation and the identification of Sporothrix spp. in clinical specimen is still the gold standard. Currently sporotrichosis epidemics requires the knowledge of the epidemiological-molecular profile to control the disease and the specific treatment. Itraconazole, potassium iodide, terfinafine, and amphotericin B are the available drugs in Brazil to treat sporotrichosis. The drug of choice, its posology, and treatment duration vary according to the clinical presentation, the Sporothrix species, and host immune status. New treatment choices, including a vaccine, are being developed; nevertheless, more clinical trials are required to confirm its efficacy. PMID:29166494

Full Text Available Rickets presents osteomalacia which is developed due to negative balance of calcium and / or phosphorus during growth and development. Therefore it appears only in children. The most common reason of insufficient mineralization is deficiency of vitamin D, which is necessary for inclusion of calcium in cartilage and bones. As result, proliferation of cartilage and bone tissue appears, creating calluses on typical places. Bones become soft and curve, resulting in deformities. Our present study included 86 infants, in whom, besides other diseases, clinical and laboratory signs of rickets were identified. In our study, rickets is most common (82.5% in infants older than 6 months. By clinical picture, craniotabes is present in 46.5% of cases, Harisson groove in 26.7%, rachitic bracelets in 17.4%, rachitic rosary in 17.4% and carpopedal spasms in 2.3% of cases. Leading biochemical signs of vitamin D deficient rickets is hypophosphatemia (in 87.3% of cases, normal calcemia (in 75.6% of cases and increased values of alkaline phosphatase (in 93% of cases. It has been shown that rickets in infant age may later affect higher incidence of juvenile diabetes, infection of lower respiratory tract, osteoporosis, and so on.

Full Text Available The medical records of 84 patients submitted to extensive thyroidectomy from January 1991 to April 1995 were reviewed and the data was analyzed in order to verify a correlation between postoperative laboratories results and physical findings suggestive of hypocalcemia. It was verified that there was hypocalcemia in 51.2 percent of the patients, of which only 18.6 percent presented symptoms. It was concluded that asymptomatic hypocalcemia is frequent in extensive thyroidectomy and a routine screening for serum calcium in the postoperative period following thyroidectomy and calcium reposition must be systematic.

Although major depressive disorder (MDD) has a variety of symptoms beyond the affective dimensions, the factor structure and contents of comprehensive psychiatric symptoms of this disorder have rarely been explored using the 18-item Brief Psychiatric Rating Scale (BPRS). We aimed to identify the factor structure of the 18-item BPRS in Korean MDD patients. A total of 258 MDD patients were recruited from a multicenter sample of the Clinical Research Center for Depression of South Korea study. Psychometric scales were used to assess overall psychiatric symptoms (BPRS), depression (Hamilton Depression Rating Scale), anxiety (Hamilton Anxiety Rating Scale), global severity (Clinical Global Impression of Severity Scale), suicidal ideation (Scale for Suicide Ideation), functioning (Social and Occupational Functioning Assessment Scale), and quality of life (World Health Organization Quality of Life Assessment-abbreviated version). Common factor analysis with oblique rotation was used to yield factor structure. A four-factor structure was designed and interpreted by the symptom dimensions to reflect mood disturbance, positive symptoms/apathy, bipolarity, and thought distortion/mannerism. These individual factors were also significantly correlated with clinical variables. The findings of this study support the view that the BPRS may be a promising measuring tool for the initial assessment of MDD patients. In addition, the four-factor structure of the BPRS may be useful in understanding the mood and psychotic characteristics of these patients. Copyright © 2014. Published by Elsevier Taiwan.

In recent years, the prevalence of in vivo molecular imaging applications has rapidly increased. Here we report on the construction of a multi-modality imaging facility in a pharmaceutical setting that is expected to further advance existing capabilities for in vivo imaging of drug distribution and the interaction with their target. The imaging instrumentation in our facility includes a microPET scanner, a four wavelength time-domain optical imaging scanner, a 9.4T/30cm MRI scanner and a SPECT/X-ray CT scanner. An electronics shop and a computer room dedicated to image analysis are additional features of the facility. The layout of the facility was designed with a central animal preparation room surrounded by separate laboratory rooms for each of the major imaging modalities to accommodate the work-flow of simultaneous in vivo imaging experiments. This report will focus on the design of and anticipated applications for our microPET and optical imaging laboratory spaces. Additionally, we will discuss efforts to maximize the daily throughput of animal scans through development of efficient experimental work-flows and the use of multiple animals in a single scanning session.
Full Text Available Despite availability of many antifungal agents, antifungal clinical resistance occurs, perhaps as a result of an infecting organism found to be resistant in vitro to one or more antifungals tested. Thus, antifungal susceptibility testing (AFST results, if timely generated by the clinical microbiology and communicated to clinicians, can aid them in the therapeutic decision making, especially for difficult-to-treat invasive candidiasis and aspergillosis. Although recently refined AFST methods are commercially available to allow a close antifungal resistance surveillance in many clinical setting, novel assays, relying on short-time antifungal drug exposure of fungal isolates, are upcoming tools for AFST. Based on emerging technologies such as flow cytometry, MALDI-TOF mass spectrometry, and isothermal microcalorimetry, these assays could provide a reliable means for quicker and sensitive assessment of AFST.

Despite clinical practice guidelines recommending the routine provision of nicotine dependence treatment to smokers in inpatient psychiatric facilities, the prevalence of such treatment provision is low. The aim of this study was to examine the effectiveness of a clinical practice change intervention in increasing clinician recorded provision of nicotine dependence treatment to patients in inpatient psychiatric facilities. We undertook an interrupted time series analysis of nicotine dependence treatment provision before, during and after a clinical practice change intervention to increase clinician recorded provision of nicotine dependence treatment for all hospital discharges (aged >18 years, N = 4175) over a 19 month period in two inpatient adult psychiatric facilities in New South Wales, Australia. The clinical practice change intervention comprised six key strategies: leadership and consensus, enabling systems and procedures, training and education, information and resources, audit and feedback and an on-site practice change support officer. Systematic medical record audit and segmented logistic regression was used to determine differences in proportions for each nicotine dependence treatment outcome measure between the 'pre', 'during' and 'post-intervention' periods. The prevalence of all five outcome measures increased significantly between the pre and post-intervention periods, including clinician recorded: assessment of patient smoking status (36.43 to 51.95%; adjusted odds ratio [AOR] = 2.39, 99% Confidence Interval [CI]: 1.23 to 4.66); assessment of patient nicotine dependence status (4.74 to 11.04%; AOR = 109.67, 99% CI: 35.35 to 340.22); provision of brief advice to quit (0.85 to 8.81%; AOR = 97.43, 99% CI: 31.03 to 306.30); provision of nicotine replacement therapy (8.06 to 26.25%; AOR = 19.59, 99% CI: 8.17 to 46.94); and provision of nicotine dependence treatment on discharge (8.82 to 13.45%, AOR = 12.36; 99% CI: 6.08 to 25

We performed customer satisfaction surveys for physicians and nurses regarding clinical laboratory services, and for outpatients who used phlebotomy services at a tertiary care unit level to evaluate our clinical laboratory and phlebotomy services. Thus, we wish to share our experiences with the customer satisfaction survey for clinical laboratory and phlebotomy services. Board members of our laboratory designed a study procedure and study population, and developed two types of questionnaire. A satisfaction survey for clinical laboratory services was conducted with 370 physicians and 125 nurses by using an online or paper questionnaire. The satisfaction survey for phlebotomy services was performed with 347 outpatients who received phlebotomy services by using computer-aided interviews. Mean satisfaction scores of physicians and nurses was 58.1, while outpatients' satisfaction score was 70.5. We identified several dissatisfactions with our clinical laboratory and phlebotomy services. First, physicians and nurses were most dissatisfied with the specimen collection and delivery process. Second, physicians and nurses were dissatisfied with phlebotomy services. Third, molecular genetic and cytogenetic tests were found more expensive than other tests. This study is significant in that it describes the first reference survey that offers a survey procedure and questionnaire to assess customer satisfaction with clinical laboratory and phlebotomy services at a tertiary care unit level.

The EQAPOL contract was awarded to Duke University to develop and manage global proficiency testing programs for flow cytometry-, ELISpot-, and Luminex bead-based assays (cytokine analytes), as well as create a genetically diverse panel of HIV-1 viral cultures to be made available to National Institutes of Health (NIH) researchers. As a part of this contract, EQAPOL was required to operate under Good Clinical Laboratory Practices (GCLP) that are traditionally used for laboratories conducting endpoint assays for human clinical trials. EQAPOL adapted these guidelines to the management of proficiency testing programs while simultaneously incorporating aspects of ISO/IEC 17043 which are specifically designed for external proficiency management. Over the first two years of the contract, the EQAPOL Oversight Laboratories received training, developed standard operating procedures and quality management practices, implemented strict quality control procedures for equipment, reagents, and documentation, and received audits from the EQAPOL Central Quality Assurance Unit. GCLP programs, such as EQAPOL, strengthen a laboratory's ability to perform critical assays and provide quality assessments of future potential vaccines. © 2013.

To discover the quality of written instructions from dentists to dental technicians and the nature of non-compliant prescriptions. An audit of laboratory prescription compliance was conducted within an NHS Trust Dental Teaching Hospital to determine the level of communication between dentists and dental technicians. One hundred and fifty prescriptions were audited from dental undergraduates and qualified dentists throughout the different departments. A total of two-thirds of prescriptions were considered non-compliant and failed to meet relevant ethical and legal guidelines. This problem was seen throughout all departments and at all professional levels. A breakdown in communication between dentists and technicians through the use of prescriptions is evident even within a close working environment.

Full Text Available BACKGROUND Since 1989, several investigators have reported unusual cases of severe opportunistic infections associated with CD4 lymphocytopenia in the absence of human immunodeficiency virus infection. The cause of this condition is unknown. The Centres for Disease Control and Prevention (CDC defines Idiopathic CD4 T Lymphocytopenia (ICL as a clinical condition in which patients with depressed numbers of circulating CD4+ T-cell lymphocytes (<300 cells/μL or <20% of total T cells at a minimum of two separate time points at least 6 weeks apart, have no laboratory evidence of infection with human HIV-1 or HIV-2, or any defined immunodeficiency or therapy associated with depressed levels of CD4 T cells. The aim of the study is to analyse the clinical profile, opportunistic infections, laboratory parameters and outcome in terms of survival of patients diagnosed with ICL. MATERIALS AND METHODS Eight HIV negative patients who presented with opportunistic infections and who were diagnosed with ICL from 2007 to 2015 were included in the study. A detailed history was taken; physical examination was performed and the nature of illness with which they presented was documented. Then, CD4 and CD8 counts were done and CD4 count was repeated after a 6-week interval. The patients were followed up until discharge or death. RESULTS The mean age was 37.50±9.55 years. There were six males (75% and two females (25%. Fever was a presenting symptom among six (75% of them. Two were diagnosed to have cutaneous cryptococcosis (25%, two with invasive aspergillosis (25% and four with tuberculosis (50%. Absolute lymphocyte count was less than 1200 in seven patients (87.5%, which roughly correlates with a CD4 count of less than 200 cells/μL, among PLWHIV. The mean CD4 count was 183.63±63.74 cells/μL during the first measurement and 214.43±103.98 cells/μL during the second one. Two patients died (37.5%. None of the patients were recorded to have any form of malignancy
Full Text Available Recently, David Barlow (2004, a pioneer in the field of anxiety disorders, has proposed that psychologists should abandon the concept of psychotherapy and rather use the one of “psychological treatment”. The provoking idea behind this proposal is that the concept of psychotherapy, relying on the notion of “therapeutic school” should be discarded by professional psychologists because it relies too much on conceptions based on pre-scientific models. Barlow (2004 insists that, today, psychology as an empirical science has gathered sufficient knowledge and know-how to found clinical practice. It is no longer necessary to rely on pre-scientific theories. Further, Barlow’s perspective opens clinical practice to the entire field of psychology, i.e. to the advances accomplished by research on emotion, cognition, learning, development, etc.

Full Text Available The mucopolysaccharidoses (MPS are a heterogeneous group of inborn errors of lysosomal glycosaminoglycan (GAG metabolism. The importance of this group of disorders among the inborn errors of metabolism led us to report 19 cases. METHOD: We performed clinical, radiological, and biochemical evaluations of the suspected patients, which allowed us to establish a definite diagnosis in 19 cases. RESULTS: Not all patients showed increased GAG levels in urine; enzyme assays should be performed in all cases with strong clinical suspicion. The diagnosis was made on average at the age of 48 months, and the 19 MPS cases, after a full clinical, radiological, and biochemical study, were classified as follows: Hurler -- MPS I (1 case; Hunter -- MPS II (2 cases; Sanfilippo -- MPS III (2 cases; Morquio -- MPS IV (4 cases; Maroteaux-Lamy -- MPS VI (9 cases; and Sly -- MPS VII (1 case. DISCUSSION: The high relative frequency of Maroteaux-Lamy disease contrasts with most reports in the literature and could express a population variability.

To identify states with laws that restrict to whom clinical laboratories may release copies of laboratory test results and to describe how these laws may affect pharmacists' ability to obtain patient laboratory test results. Researchers examined state statutes and administrative codes for all 50 states and the District of Columbia at the University of Iowa Law Library between June and July 2007. Researchers also consulted with lawyers, state Clinical Laboratory Improvement Amendments officers, and law librarians. Laws relating to the study objective were analyzed. 34 jurisdictions do not restrict the release of laboratory test results, while 17 states have laws that restrict to whom clinical laboratories can send copies of test results. In these states, pharmacists will have to use alternative sources, such as physician offices, to obtain test results. Pharmacists must consider state law before requesting copies of laboratory test results from clinical laboratories. This may be an issue that state pharmacy associations can address to increase pharmacist access to important patient information.

Studies of the causes of cancer, early detection, prevention or treatment need accurate, comprehensive, and timely cancer data. The clinical laboratory provides important cancer information needed for physicians which influence clinical decisions regarding treatment, diagnosis and patient monitoring. Poor communication between health care providers and clinical laboratory personnel can lead to medical errors and wrong decisions in providing cancer care. Because of the key impact of laboratory information on cancer diagnosis and treatment the quality of the tests, lab reports, and appropriate lab management are very important. A laboratory information management system (LIMS) can have an important role in diagnosis, fast and effective access to cancer data, decrease redundancy and costs, and facilitate the integration and collection of data from different types of instruments and systems. In spite of significant advantages LIMS is limited by factors such as problems in adaption to new instruments that may change existing work processes. Applications of intelligent software simultaneously with existing information systems, in addition to remove these restrictions, have important benefits including adding additional non-laboratory-generated information to the reports, facilitating decision making, and improving quality and productivity of cancer care services. Laboratory systems must have flexibility to change and have the capability to develop and benefit from intelligent devices. Intelligent laboratory information management systems need to benefit from informatics tools and latest technologies like open sources. The aim of this commentary is to survey application, opportunities and necessity of intelligent clinical laboratory as a tool to increase cancer care management productivity.
In the last few decades, laboratory medicine has undergone monumental changes, and laboratory technology, which has made enormous advances, now has new clinical applications thanks to the identification of a growing number of biomarkers and risk factors conducive to the promotion of predictive and preventive interventions that have enhanced the role of laboratory medicine in health care delivering. However, the paradigm shift in the past 50 years has led to a gap between laboratory and clinic, with an increased risk of inappropriateness in test request and interpretation, as well as the consolidation of analytical work in focused factories and megastructurers oriented only toward achieving greater volumes, decreasing cost per test and generating a vision of laboratory services as simple commodities. A careful historical revision of the changing models for delivering laboratory services in the United States leads to the prediction that there are several reasons for counteracting the vision of clinical laboratory as a commodity, and restoring the true nature of laboratory services as an integral part of the diagnosis and therapy process. The present study, which reports on internal and external drivers for change, proposes an integrated vision of quality in laboratory medicine.

Full Text Available Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut. Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow's milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%. Only five patients (2% had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00. The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008.Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted.

The use of calcium-phosphate casein on hypomineralized molars (molar incisor hypomineralization, MIH) has been proposed but not clinically investigated. Qualitative and quantitative effects of supplementation with a calcium-phosphate casein product on MIH molars were monitored over a period of three years. Molar replicas, minimally invasive biopsies and their SEM microphotographs, plus ESEM/EDX semi-quantitative peaks of elements present in affected enamel were evaluated. Mineralization, morphology, and porosity appeared markedly improved, with calcium and phosphate levels reaching almost normal levels at three years' follow-up. The hypothesis tested was rejected, since calcium-phosphate casein improved enamel morphology in vivo.

Despite recent advances in diagnostic technology, microscopic examination of stool specimens remains central to the diagnosis of most pathogenic intestinal protozoa. Microscopy is, however, labor-intensive and requires a skilled technologist. New, highly sensitive diagnostic methods have been developed for protozoa endemic to developed countries, including Giardia lamblia (syn. G. intestinalis/G. duodenalis) and Cryptosporidium spp., using technologies that, if expanded, could effectively complement or even replace microscopic approaches. To date, the scope of such novel technologies is limited and may not include common protozoa such as Dientamoeba fragilis, Entamoeba histolytica, or Cyclospora cayetanensis. This minireview describes canonical approaches for the detection of pathogenic intestinal protozoa, while highlighting recent developments and FDA-approved tools for clinical diagnosis of common intestinal protozoa.

For twenty years, mass spectrometry (MS) has emerged as a particularly powerful tool for analysis and characterization of proteins in research. It is only recently that this technology, especially MALDI-TOF-MS (Matrix Assisted Laser Desorption Ionization Time-Of-Flight) has entered the field of routine microbiology. This method has proven to be reliable and safe for the identification of bacteria, yeasts, filamentous fungi and dermatophytes. MALDI-TOF-MS is a rapid, precise and cost-effective method for identification, compared to conventional phenotypic techniques or molecular biology. Its ability to analyse whole microorganisms with few sample preparation has greatly reduced the time to identification (1-2 min). Furthermore, this technology can be used to identify bacteria directly from clinical samples as blood culture bottles or urines. Future applications will be developed in order to provide direct information concerning virulence or resistance protein markers. © 2011 médecine/sciences – Inserm / SRMS.

Full Text Available Background/Aim. Antidepressants are a widely used class of drugs. The aim of this study was to investigate different aspects of antidepressant prescribing practice at University Psychiatric Clinic in Belgrade. Methods. This cross-sectional study was carried out by retrospective analysis of the patient's medical charts. The study included all patients with antidepressant prescribed at discharge during 2009 (n = 296. The evaluation was focused on patient- related factors (socio-demographic and illness related, psychiatrist-related factors (sex and duration of working experience and drug related factors (type of antidepressant, dose, polypharmacy and reimbursement by national health insurance.

The Clinical Laboratory Improvement Amendments of 1988 (CLIA'88) mandate universal requirements for all U.S. clinical laboratory-testing sites. The intent of CLIA'88 is to ensure quality testing through a combination of minimum quality practices that incorporate total quality management concepts. These regulations do not contain established, objective indicators or measures to assess quality. However, there is an implicit assumption that compliance with traditionally accepted good laboratory practices--following manufacturers' directions, routinely analysing quality control materials, applying quality assurance principles, employing and assessing competent testing personnel, and participating in external quality assessment or proficiency testing (PT)--will result in improved test quality. The CLIA'88 regulations do include PT performance standards, which intentionally or unintentionally, define intra-laboratory performance. Passing PT has become a prime motivation for improving laboratory performance; it can also be used as an objective indicator to assess whether compliance to CLIA has improved intra-laboratory quality. Data from 1994 through 2002 indicate that the percentage of laboratories passing PT has increased. In addition to PT performance, subjective indicators of improved quality--frequency of inspection deficiencies, the number of government sanctions for non-compliance, and customer satisfaction--were evaluated. The results from these subjective indicators are more difficult to interpret but also seem to show improved quality in US clinical laboratories eleven years post-CLIA'88.
As of January 1, 2016, microbiology laboratories can choose to adopt a new quality control option, the Individualized Quality Control Plan (IQCP), under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). This voluntary approach increases flexibility for meeting regulatory requirements and provides laboratories the opportunity to customize QC for their testing in their unique environments and by their testing personnel. IQCP is an all-inclusive approach to quality based on risk management to address potential errors in the total testing process. It includes three main steps, (1) performing a risk assessment, (2) developing a QC plan, and (3) monitoring the plan through quality assessment. Resources are available from the Centers for Medicare & Medicaid Services, Centers for Disease Control and Prevention, American Society for Microbiology, Clinical and Laboratory Standards Institute, and accrediting organizations, such as the College of American Pathologists and Joint Commission, to assist microbiology laboratories implementing IQCP.

Psychiatric consultation in primary care is meant to enhance and improve treatment for mental disorder in that setting. An estimate of the effect for different conditions as well as identification of particularly effective elements is needed. Database search for randomized controlled trials (RCTs) on psychiatric consultation in primary care. Validity assessment and data extraction according to Cochrane criteria were performed by independent assessors in duplicate. Meta-analysis was performed. Data were collected from 10 RCTs with a total of 3408 included patients with somatoform disorder or depressive disorder, which compared psychiatric consultation to care as usual (CAU). Meta-analysis irrespective of condition showed a weighted mean indicating a combined assessment of illness burden as outcome of psychiatric consultation, compared to CAU, of 0.313 (95% CI 0.190-0.437). The effect was especially large in somatoform disorder (0.614; 95% CI 0.206-1.022). RCTs in which after the consult, consultation advice was given by means of a consultation letter, showed a combined weighted mean effect size of 0.561 (95% CI 0.337-0.786), while studies not using such a letter showed a small effect of 0.210 (95% CI 0.102-0.319). Effects are highest on utilization of health care services with 0.507 (95% CI 0.305-0.708). Psychiatric consultation in the primary care setting is effective in patients with somatoform and depressive disorder. Largest effects are seen in reduction of utilization of health care services.

In the early 80s, the word automation was used in the clinical laboratory setting referring only to analyzers. But in late 80s and afterwards, automation found its way into all aspects of the diagnostic process, embracing not only the analytical but also the pre- and post-analytical phase. While laboratories in the eastern world, mainly Japan, paved the way for laboratory automation, US and European laboratories soon realized the benefits and were quick to follow. Clearly, automation and robotics will be a key survival tool in a very competitive and cost-concious healthcare market. What sets automation technology apart from so many other efficiency solutions are the dramatic savings that it brings to the clinical laboratory. Further standardization will assure the success of this revolutionary new technology. One of the main difficulties laboratory managers and personnel must deal with when studying solutions to reengineer a laboratory is familiarizing themselves with the multidisciplinary and technical terminology of this new and exciting field. The present review/glossary aims at giving an overview of the most frequently used terms within the scope of laboratory automation and to put laboratory automation on a sounder linguistic basis.

Notification of critical values to clinical staff is an important post-analytical process in all acute care clinical laboratories. No data are available however on how laboratories obtain or establish critical values, particularly in pediatric settings. This study was designed to examine and compare critical values used for pediatric patients in biochemistry laboratories in Canada and assess potential interlaboratory variability. Fourteen clinical laboratories, including two in pediatric hospitals and twelve in hospitals caring for both children and adults, participated in a survey that included 14 pre-selected STAT chemistry tests and 19 pre-selected therapeutic drug monitoring (TDM) tests. Among fourteen chemistry tests, good agreement was observed for critical values used for sodium and pH at both low and high levels within 14 participant laboratories. Significant interlaboratory variability existed for glucose critical values at the high end, magnesium at high end, and PO2 at the low end. For 19 TDM tests, the majority of laboratories did not have alert values to report values over the therapeutic level but not toxic. For critical values greater than the toxic range, significant variability existed at both trough and peak levels among laboratories surveyed. When asked to provide the source for critical values established at each site, only a limited number of laboratories identified their sources as either internal decision or published references. Although all laboratories have established and routinely use critical values to alert clinical staff, considerable variability exists in both the critical limits reported as well as the source of such values. There is a clear need for new national efforts to standardize pediatric critical value reporting and establish evidence-based critical limits for all medical laboratories across Canada.
Full Text Available Brucellosis is a multisystem disease with diverse clinical presentations and involvement of the nervous system is considered to 5 to be 10% in adult patients and 1% in children. The presentations of neurobrucellosis includes meningoencephalitis, subarachnoid haemorrhage, myelitis, radiculoneuritis, intracerebral and epidural abscess, psychosis and vascular syndrome. Twenty-two patients with neurobrucellosis are described. Ten patients had meningoencephalitis, seven patients had meningitis, three patients had polyradiculopathy and one patient presented with spinal epidural abscess and one patient had brain abscess. Results of an agglutination test for Brucella in serum were positive for all patients (>1:160; eight of 15 patients had positive agglutination test in CSF. Five patients had positive blood cultures, 3 patients had positive bone marrow cultures and 2 of 15 patients had positive CSF cultures. All of cultures were Brucella Mellitensis. Antimicrobial treatment included concurrent administration of Doxycycline, Rifampin and Trimethoprim-Sulfametoxazole. Four patients received Dexamethason concurrently. In conclusion, nervous system involvement is a serious manifestation of brucellosis. As brucellosis is an endemic disease in Iran we suggest that brucellosis be investigated with neurological symptoms and signs.

Full Text Available Objective: To evaluate a pilot of a laboratory model for relating pharmacogenetics to clinical decision making. Case Study: This pilot was undertaken and evaluated to help determine if a pharmacogenetics laboratory should be included in the core Doctor of Pharmacy curriculum. The placement of the laboratory exercise in the curriculum was determined by identifying the point in the curriculum where the students had been introduced to the chemistry of deoxyribonucleic acid (DNA as well as instructed on the chemistry of genetic variation. The laboratory included cytochrome P450 2C19 genotyping relative to the *2 variant. Twenty-four students served as the pilot group. Students provided buccal swabs as the source of DNA. Students stabilized the samples and were then provided instructions related to sample preparation, polymerase chain reaction, and gel electrophoresis. The results were reported as images of gels. Students used a reference gel image to compare their results to. Students then applied a dosing algorithm to make a “clinical decision” relative to clopidogrel use. Students were offered a post laboratory survey regarding attitudes toward the laboratory. Twenty-four students completed the laboratory with genotyping results being provided for 22 students (91.7%. Sixteen students were wild-type (*1/*1, while six students were heterozygous (*1/*2. Twenty-three students (96% completed the post laboratory survey. All 23 agreed (6, 26.1% or strongly agreed (17, 73.9% that the laboratory “had relevance and value in the pharmacy curriculum”. Conclusion: The post pilot study survey exploring a laboratory model for pharmacogenetics related to clinical decision making indicated that such a laboratory would be viewed positively by students. This model may be adopted by colleges to expand pharmacogenetics education.

Critical value policies are used by clinical laboratories to decide when to notify caregivers of life-threatening results. Despite their widespread use, critical value policies have not been published locally. A survey was designed to determine critical value policies for haematology tests in South Africa. A survey was carried out on 136 identified laboratories across South Africa in January 2013. Of these, 36 responded. Data collected included critical value policies, critical values for haematology parameters, and critical value reporting. Of the 36 laboratories surveyed, 11.1% (n=4) were private, 33.3% (n=12) were affiliated to academic institutions and 55.6% (n=20) were peripheral or regional National Health Laboratory Service laboratories. All the laboratories confirmed that they had a critical value policy, and 83.3% of such policies were derived from local clinical opinion. Mean low and high critical limits for the most frequently listed tests were as follows: haemoglobin 20 g/dl, platelet count 1 000 ×10(9)/l, white cell count 46 ×10(9)/l, activated partial thromboplastin time >101 seconds, and international normalised ratio >6. In almost all cases critical value reporting was performed by the technologist on duty (97.2%). The majority of laboratories required that the person notified of the critical value be the doctor who ordered the test or the caregiver directly involved in the patient's care (83.3%); 73.3% of laboratories indicated that they followed an algorithm if the doctor/caregiver could not be reached. Each laboratory is responsible for establishing clinically relevant critical limits. Clinicians should be involved in developing the laboratory's critical value policy. The findings of this survey may be of value to local laboratories that are in the process of establishing or reviewing critical value policies.

Competency assessment is critical for laboratory operations and is mandated by the Clinical Laboratory Improvement Amendments of 1988. However, no previous reports describe methods for assessing competency in patient safety. We developed and implemented a Web-based tool to assess performance of 875 laboratory staff from 29 laboratories in patient safety. Question categories included workplace culture, categorizing error, prioritization of patient safety interventions, strength of specific interventions, and general patient safety concepts. The mean score was 85.0%, with individual scores ranging from 56% to 100% and scores by category from 81.3% to 88.6%. Of the most difficult questions (laboratory technologists. Computer-based competency assessments help laboratories identify topics for continuing education in patient safety.

Full Text Available Background: Paroxysmal nocturnal hemoglobinuria (PNH is characterized by intravascular hemolysis, marrow failure, nocturnal hemoglobinuria and thrombophila. This acquired disease caused by a deficiency of glycosylphosphatidylinositol (GPI anchored proteins on the hematopoietic cells is uncommon in the Indian population. Materials and Methods: Data of patients diagnosed with PNH in the past 1 year were collected. Clinical data (age, gender, various presenting symptoms, treatment information and follow-up data were collected from medical records. Results of relevant diagnostic tests were documented i.e., urine analysis, Ham′s test, sucrose lysis test and sephacryl gel card test (GCT for CD55 and CD59. Results: A total of 5 patients were diagnosed with PNH in the past 1 year. Presenting symptoms were hemolytic anemia (n=4 and bone marrow failure (n=1. A GCT detected CD59 deficiency in all erythrocytes in 4 patients and CD55 deficiency in 2 patients. A weak positive PNH test for CD59 was seen in 1 patient and a weak positive PNH test for CD55 was seen in 3 patients. All patients were negative by sucrose lysis test. Ham′s test was positive in two cases. Patients were treated with prednisolone and/or androgen and 1 patient with aplastic anemia was also given antithymocyte globulin. A total of 4 patients responded with a partial recovery of hematopoiesis and 1 patient showed no recovery. None of the patients received a bone marrow transplant. Conclusion: The study highlights the diagnostic methods and treatment protocols undertaken to evaluate the PNH clone in a developing country where advanced methods like flowcytometry immunophenotyping (FCMI and bone marrow transplants are not routinely available.

Hemolysis is an important clinical laboratory quality attribute that influences result reliability. To determine hemolysis identification and rejection practices occurring in clinical laboratories. We used the College of American Pathologists Survey program to distribute a Q-Probes-type questionnaire about hemolysis practices to Chemistry Survey participants. Of 3495 participants sent the questionnaire, 846 (24%) responded. In 71% of 772 laboratories, the hemolysis rate was less than 3.0%, whereas in 5%, it was 6.0% or greater. A visual scale, an instrument scale, and combination of visual and instrument scales were used to identify hemolysis in 48%, 11%, and 41% of laboratories, respectively. A picture of the hemolysis level was used as an aid to technologists' visual interpretation of hemolysis levels in 40% of laboratories. In 7.0% of laboratories, all hemolyzed specimens were rejected; in 4% of laboratories, no hemolyzed specimens were rejected; and in 88% of laboratories, some specimens were rejected depending on hemolysis levels. Participants used 69 different terms to describe hemolysis scales, with 21 terms used in more than 10 laboratories. Slight and moderate were the terms used most commonly. Of 16 different cutoffs used to reject hemolyzed specimens, moderate was the most common, occurring in 30% of laboratories. For whole blood electrolyte measurements performed in 86 laboratories, 57% did not evaluate the presence of hemolysis, but for those that did, the most common practice in 21 laboratories (24%) was centrifuging and visually determining the presence of hemolysis in all specimens. Hemolysis practices vary widely. Standard assessment and consistent reporting are the first steps in reducing interlaboratory variability among results.
Full Text Available Introduction: Over the last five decades, general hospital psychiatric units (GHPUs have become important mental health service setups in India. The present study reports on the changing clinical profile of the patients attending the GHPUs over the last five decades. Methodology: A total of 500 subjects, attending a GHPU were recruited prospectively for the study. The subjects were assessed using a semistructured proforma. A comparison was made with similar studies conducted in GHPU settings over the last five decades. Results: In the present study, neurotic, stress-related and somatoform disorders formed the commonest diagnostic group (33% followed by psychotic disorders (17% and mood disorders (15%. The diagnostic distribution is broadly similar to the studies done at different times in the last 5 decades, though there were lesser number of patients with mental retardation and organic brain syndrome. About 15% of the subjects did not have a psychiatric diagnosis. Conclusion: GHPUs in India attend to a broad range of patients with psychiatric disorders.
Full Text Available Dermatological drugs, mostly corticosteroids and isotretinoin, cause different psychiatric adverse effects. During steroid therapy, a wide range of psychiatric conditions, from minor clinical symptoms like insomnia and anxiety to serious psychiatric syndromes like psychosis and delirium might be seen. In medical literature, a causal connection is usually suggested between “isotretinoin”, which is used for treatment of acne vulgaris and depression and suicide attempts. However, there are no statistically significant double-blind randomized studies that support this connection. Clinicians must know patient’s psychiatric history before using any dermatological treatment known as causing psychiatric adverse effects, and psychiatric consultation should be established whenever necessary.
Full Text Available In the last 20 years in medical laboratories, numerous activities regarding quality and accreditation system were taken. Approach to this problem in European countries is different, so the task of the Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 to help the efforts to harmonize this issue. External quality control in clinical-chemical laboratories imposed the need for the implementation of quality management system. »Good laboratory practice« and its principles were adopted by nominated bodies, both international and national. In the beginning, the standard ISO 9001 was applied for certification and for accreditation EN 45001 and ISO Guide 25, which are prepared for testing and calibration laboratories. Standard ISO 17025 is the successor of the previous documents and for now it is a reference for mentioned laboratories. Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 made an amendment of the requirements for medical laboratories, which this standard describes. Standard draft ISO 15189 was adopted on February 2003 as a final version with requirements for medical laboratories.

Clinical laboratories are potentially hazardous work areas. Health and safety in clinical laboratories is becoming an increasingly important subject as a result of the emergence of highly infectious diseases such as hepatitis and HIV. This is even more so in developing countries where health and safety have traditionally been regarded as low priority issues, considering the more important health problems confronting the health authorities in these countries. We conducted a literature search using the medical subheadings titles on the INTERNET over a period of twenty years and summarized our findings. This article identifies hazards in the laboratories and highlights measures to make the laboratory a safer work place. It also emphasizes the mandatory obligations of employers and employees towards the attainment of acceptable safety standards in clinical laboratories in Third World countries in the face of the current HIV/AIDS epidemic in many of these developing countries especially in the sub-Saharan Africa while accommodating the increasing work load in these laboratories. Both the employer and the employee have major roles to play in the maintenance of a safe working environment. This can be achieved if measures discussed are incorporated into everyday laboratory practice.

To search for possible early clinical associations and laboratory abnormalities in children with severe dehydration in northern Jordan. We prospectively evaluated 251 children with acute gastroenteritis. Dehydration assessment was done following a known clinical scheme. Probable clinical associations and laboratory abnormalities were examined against the preassigned dehydration status. Children with severe dehydration had significantly more hypernatremia and hyperkalemia, less isonatremia, and higher mean levels of urea, creatinine, and glucose (P dehydration. Historic clinical characteristics of patients did not correlate to dehydration degree. Serum urea, creatinine, sodium, potassium, and glucose were useful independently in augmenting clinical examination to diagnose the degree of dehydration status among children presenting with gastroenteritis. Serum urea performed the best among all. On the contrary, none of the examined historical clinical patterns could be correlated to the dehydration status. Larger and multicenter studies are needed to validate our results and to examine their impact on final outcomes.

A common laboratory practice is to repeat critical values before reporting the test results to the clinical care provider. This may be an unnecessary step that delays the reporting of critical test results without adding value to the accuracy of the test result. To determine the proportions of repeated chemistry and hematology critical values that differ significantly from the original value as defined by the participating laboratory, to determine the threshold differences defined by the laboratory as clinically significant, and to determine the additional time required to analyze the repeat test. Participants prospectively reviewed critical test results for 4 laboratory tests: glucose, potassium, white blood cell count, and platelet count. Participants reported the following information: initial and repeated test result; time initial and repeat results were first known to laboratory staff; critical result notification time; if the repeat result was still a critical result; if the repeat result was significantly different from the initial result, as judged by the laboratory professional or policy; significant difference threshold, as defined by the laboratory; the make and model of the instrument used for primary and repeat testing. Routine, repeat analysis of critical values is a common practice. Most laboratories did not formally define a significant difference between repeat results. Repeated results were rarely considered significantly different. Median repeated times were at least 17 to 21 minutes for 10% of laboratories. Twenty percent of laboratories reported at least 1 incident in the last calendar year of delayed result reporting that clinicians indicated had adversely affected patient care. Routine repeat analysis of automated chemistry and hematology critical values is unlikely to be clinically useful and may adversely affect patient care.

To assess the predictive ability of various aspects of the work environment for organizational commitment. A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals. All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006. Only respondents who worked full-time in a clinical laboratory setting were included in the database. Levels of affective, normative, and continuance organizational commitment, organizational support, role clarity, role conflict, transformational leadership behavior of supervisor, and organizational type, total years work experience in clinical laboratories, and educational level of respondents. Questionnaire items used either a 7-point or 5-point Likert response scale. Based on multiple regression analysis for the 427 respondents, organizational support and transformational leadership behavior were found to be significant positive predictors of affective and normative organizational commitment. Work setting (non-hospital laboratory) and total years of work experience in clinical laboratories were found to be significant positive predictors of continuance organizational commitment. Overall the organizational commitment levels for all three dimensions were at the neutral rating or below in the slightly disagree range. The results indicate a less than optimal level of organizational commitment to employers, which were predominantly hospitals, by CLS practitioners. This may result in continuing retention problems for hospital laboratories. The results offer strategies for improving organizational commitment via the significant predictors.
Full Text Available Children suffer the highest burden of enteric fever among populations in South Asian countries. The clinical features are non–specific, vary in populations, and are often difficult to distinguish clinically from other febrile illnesses, leading to delayed or inappropriate diagnosis and treatment. We undertook a systematic review to assess the clinical profile and laboratory features of enteric fever across age groups, economic regions, level of care and antibiotic susceptibility patterns.

A "learning health care system", as outlined in a recent Institute of Medicine report, harnesses real-time clinical data to continuously measure and improve clinical care. However, most current efforts to understand and improve the quality of care rely on retrospective chart abstractions complied long after the provision of clinical care. To align more closely with the goals of a learning health care system, we present the novel design and initial results of the Veterans Affairs (VA) Clinical Assessment, Reporting, and Tracking (CART) program-a national clinical quality program for VA cardiac catheterization laboratories that harnesses real-time clinical data to support clinical care and quality-monitoring efforts. Integrated within the VA electronic health record, the CART program uses a specialized software platform to collect real-time patient and procedural data for all VA patients undergoing coronary procedures in VA catheterization laboratories. The program began in 2005 and currently contains data on 434,967 catheterization laboratory procedures, including 272,097 coronary angiograms and 86,481 percutaneous coronary interventions, performed by 801 clinicians on 246,967 patients. We present the initial data from the CART program and describe 3 quality-monitoring programs that use its unique characteristics-procedural and complications feedback to individual labs, coronary device surveillance, and major adverse event peer review. The VA CART program is a novel approach to electronic health record design that supports clinical care, quality, and safety in VA catheterization laboratories. Its approach holds promise in achieving the goals of a learning health care system. Published by Elsevier Inc.

Kyol goeu (literally, ‘wind overload’) is an orthostatically triggered syncopal syndrome often found among Khmer refugees in the US. In the present study, 36 of 100 (36%) Khmer patients attending a psychiatric clinic were found to have suffered a kyol goeu episode in the past, whereas 60 of 100 (60%) patients had experienced a near-kyol goeu event in the last six months. Following a survey-based characterization of kyol goeu, as well as the presentation of case vignettes, the article discusses six mechanisms resulting in the high prevalence of the syndrome. The article concludes by comparing kyol goeu and ataque de nervios. PMID:20808711

The present study used a self-reporting questionnaire to compare suicide risk in outpatients being treated for substance use disorder at specialized hospitals to suicide risk in outpatients being treated for depressive disorder at general psychiatric clinics. Although patients in both groups exhibited an equal severity of depression, the patients with drug use disorder had a higher suicide risk than those with depressive disorder. These findings indicate that drug-abusing patients at specialized hospitals may have a severe risk of committing suicide, suggesting that carefully assessing the comorbidity of depression with drug abuse may be required for preventing suicide in drug-abusing patients.

Data sharing through ClinVar offers a unique opportunity to identify interpretation differences between laboratories. As part of a ClinGen initiative, four clinical laboratories (Ambry, GeneDx, Partners Healthcare Laboratory for Molecular Medicine, and University of Chicago Genetic Services Laboratory) collaborated to identify the basis of interpretation differences and to investigate if data sharing and reassessment resolve interpretation differences by analyzing a subset of variants. ClinVar variants with submissions from at least two of the four participating laboratories were compared. For a subset of identified differences, laboratories documented the basis for discordance, shared internal data, independently reassessed with the American College of Medical Genetics and Genomics-Association for Molecular Pathology (ACMG-AMP) guidelines, and then compared interpretations. At least two of the participating laboratories interpreted 6,169 variants in ClinVar, of which 88.3% were initially concordant. Laboratories reassessed 242/724 initially discordant variants, of which 87.2% (211) were resolved by reassessment with current criteria and/or internal data sharing; 12.8% (31) of reassessed variants remained discordant owing to differences in the application of the ACMG-AMP guidelines. Participating laboratories increased their overall concordance from 88.3 to 91.7%, indicating that sharing variant interpretations in ClinVar-thereby allowing identification of differences and motivation to resolve those differences-is critical to moving toward more consistent variant interpretations.Genet Med advance online publication 09 March 2017.

Mass spectrometry (MS) has been used in research and specialized clinical laboratories for decades as a very powerful technology to identify and quantify compounds. In recent years, application of MS in routine clinical laboratories has increased significantly. This is mainly due to the ability of MS to provide very specific identification, high sensitivity, and simultaneous analysis of multiple analytes (>100). The coupling of tandem mass spectrometry with gas chromatography (GC) or liquid chromatography (LC) has enabled the rapid expansion of this technology. While applications of MS are used in many clinical areas, therapeutic drug monitoring, drugs of abuse, and clinical toxicology are still the primary focuses of the field. It is not uncommon to see mass spectrometry being used in routine clinical practices for those applications.

Many countries are on the brink of establishing antibiotic stewardship programmes in hospitals nationwide. In a previous study we found that communication between microbiology laboratories and clinical units is a barrier to implementing efficient antibiotic stewardship programmes in Norway. We have now addressed the key communication barriers between microbiology laboratories and clinical units from a laboratory point of view. Qualitative semi-structured interviews were conducted with 18 employees (managers, doctors and technicians) from six diverse Norwegian microbiological laboratories, representing all four regional health authorities. Interviews were recorded and transcribed verbatim. Thematic analysis was applied, identifying emergent themes, subthemes and corresponding descriptions. The main barrier to communication is disruption involving specimen logistics, information on request forms, verbal reporting of test results and information transfer between poorly integrated IT systems. Furthermore, communication is challenged by lack of insight into each other's area of expertise and limited provision of laboratory services, leading to prolonged turnaround time, limited advisory services and restricted opening hours. Communication between microbiology laboratories and clinical units can be improved by a review of testing processes, educational programmes to increase insights into the other's area of expertise, an evaluation of work tasks and expansion of rapid and point-of-care test services. Antibiotic stewardship programmes may serve as a valuable framework to establish these measures. © The Author 2017.

Musculoskeletal disorders (MSDs) are an important health problem among healthcare workers, including clinical laboratory ones. The aim of the present study was to investigate the prevalence of MSDs and individual and psychosocial risk factors among clinical laboratory workers. A cross-sectional study was carried out among 156 workers of 30 clinical laboratories in 3 towns of Iran. The Nordic questionnaire with individual and psychosocial risk factors was used to collect data. Multiple logistic regression analysis was performed. The prevalence of reported MSDs among the study population was 72.4% in the past 12 months. The most prevalent MSDs were pain in the lower back and neck; 42.7% and 33.3%, respectively. Significant relations were found between MSDs and age, gender, heavy work at home and job control (p workers were high and associated with age, gender, heavy work at home and job control. More research into measuring these factors and workplace physical demands is suggested.

A locally developed, computer-based clinical chemistry laboratory system has been in operation since 1970. This utilises a Digital Equipment Co Ltd PDP 12 and an interconnected PDP 8/F computer. Details are presented of the performance and quality control techniques incorporated into the system. Laboratory performance is assessed through analysis of results from fixed-level control sera as well as from cumulative sum methods. At a simple level the presentation may be considered purely indicative, while at a more sophisticated level statistical concepts have been introduced to aid the laboratory controller in decision-making processes.

This survey was initiated to obtain knowledge on the current situation of internal quality control (IQC) practice for tumour markers (TMs) in China. Additionally, we tried to acquire the most appropriate quality specifications. This survey was a current status survey. The IQC information had been collected via online questionnaires. All of 1821 clinical laboratories which participated in the 2016 TMs external quality assessment (EQA) programme had been enrolled. The imprecision evaluation criteria were the minimal, desirable, and optimal allowable imprecisions based on biological variations, and 1/3 total allowable error (TEa) and 1/4 TEa. A total of 1628 laboratories answered the questionnaires (89%). The coefficients of variation (CVs) of the IQC of participant laboratories varied greatly from 1% (5 th percentile) to 13% (95 th percentile). More than 82% (82 - 91%) of participant laboratories two types of CVs met 1/3 TEa except for CA 19-9. The percentiles of current CVs were smaller than cumulative CVs. A number of 1240 laboratories (76%) reported their principles and systems used. The electrochemiluminescence was the most used principle (45%) and had the smallest CVs. The performance of laboratories for TMs IQC has yet to be improved. On the basis of the obtained results, 1/3 TEa would be realistic and attainable quality specification for TMs IQC for clinical laboratories in China.

To implement an electronic laboratory utilization management system (laboratory expert system [LES]) to provide safe and effective reductions in unnecessary clinical laboratory testing. The LES is a set of frequency filter subroutines within the Veterans Affairs hospital and laboratory information system that was formulated by an interdisciplinary medical team. Since implementing the LES, total test volume has decreased by a mean of 11.18% per year compared with our pre-LES test volume. This change was not attributable to fluctuations in outpatient visits or inpatient days of care. Laboratory cost savings were estimated at $151,184 and $163,751 for 2012 and 2013, respectively. A significant portion of these cost savings was attributable to reductions in high-volume, large panel testing. No adverse effects on patient care were reported, and mean length of stay for patients remained unchanged. Electronic laboratory utilization systems can effectively reduce unnecessary laboratory testing without compromising patient care.

To inform the pathology and laboratory field of the most recent national wage data from the American Society for Clinical Pathology (ASCP). Historically, the results of this biennial survey have served as a basis for additional research on laboratory recruitment, retention, education, marketing, certification, and advocacy. The 2015 wage survey was conducted through collaboration between the ASCP's Institute of Science, Technology, and Policy in Washington, DC, and the ASCP Board of Certification in Chicago, Illinois. Electronic survey invitations were sent to individuals who are currently practicing in the field. Data reveal increased salaries since 2013 for all staff-level laboratory professionals surveyed except phlebotomists and pathologists' assistants. Laboratory assistants and phlebotomists, regardless of level, continue to have lower salaries while pathologists' assistants and administration personnel have higher salaries than the rest of the laboratory professions surveyed. Survey results put emphasis on strategic recruitment and retention by laboratory training programs and institutions that hire laboratory professionals. © American Society for Clinical Pathology, 2017.

To determine the extent and distribution of workforce shortages within the nation's medical laboratories. Historically, the results of this biennial survey have served as a basis for additional research on laboratory recruitment, retention, education, marketing, certification, and advocacy. The 2014 Vacancy Survey was conducted through collaboration between American Society for Clinical Pathology's Institute of Science, Technology, and Policy in Washington, DC, and the Evaluation, Measurement, and Assessment Department and Board of Certification in Chicago, Illinois. Data were collected via an Internet survey that was distributed to individuals who were able to report on staffing and certifications for their laboratories. Data reveal increased overall vacancy rates since 2012 for all departments surveyed except cytology and cytogenetics. Also, results show higher anticipated retirement rates for both staff and supervisors. Overall certification rates are highest among laboratory personnel in cytogenetics, hematology/coagulation, and flow cytometry departments and lowest among phlebotomy, specimen processing, and anatomic pathology. Factors such as retirement and the improving economy are driving the need for more laboratory professionals. Recruitment of qualified laboratory professionals in the workforce and students in laboratory programs will be the key in fulfilling the higher vacancies revealed from the survey results in 2014.

The authors conducted a 2-year prospective naturalistic follow-up study to evaluate posttreatment clinical outcomes in outpatients who were randomly selected to receive 1 year of either dialectical behavior therapy or general psychiatric management for borderline personality disorder. Patients were assessed by blind raters 6, 12, 18, and 24 months after treatment. The clinical effectiveness of treatment was assessed on measures of suicidal and nonsuicidal self-injurious behaviors, health care utilization, general symptom distress, depression, anger, quality of life, social adjustment, borderline psychopathology, and diagnostic status. The authors conducted between-group comparisons using generalized estimating equation, mixed-effects models, or chi-square statistics, depending on the distribution and nature of the data. Both treatment groups showed similar and statistically significant improvements on the majority of outcomes 2 years after discharge. The original effects of treatment did not diminish for any outcome domain, including suicidal and nonsuicidal self-injurious behaviors. Further improvements were seen on measures of depression, interpersonal functioning, and anger. However, even though two-thirds of the participants achieved diagnostic remission and significant increases in quality of life, 53% were neither employed nor in school, and 39% were receiving psychiatric disability support after 36 months. One year of either dialectical behavior therapy or general psychiatric management was associated with long-lasting positive effects across a broad range of outcomes. Despite the benefits of these specific treatments, one important finding that replicates previous research is that participants continued to exhibit high levels of functional impairment. The effectiveness of adjunctive rehabilitation strategies to improve general functioning deserves additional study.

Interpersonal psychotherapy (IPT) and cognitive behavioral therapy (CBT) are both evidence-based treatments for major depressive disorder (MDD). Several head-to-head comparisons have been made, mostly in the United States. In this trial, we compared the two treatments in a small-town outpatient psychiatric clinic in Sweden. The patients had failed previous primary care treatment and had extensive Axis-II comorbidity. Outcome measures were reduction of depressive symptoms and attrition rate. Ninety-six psychiatric patients with MDD (DSM-IV) were randomized to 14 sessions of CBT (n = 48) or IPT (n = 48). A noninferiority design was used with the hypothesis that IPT would be noninferior to CBT. A three-point difference on the Beck Depression Inventory-II (BDI-II) was used as noninferiority margin. IPT passed the noninferiority test. In the ITT group, 53.5% (23/43) of the IPT patients and 51.0% (24/47) of the CBT patients were reliably improved, and 20.9% (9/43) and 19.1% (9/47), respectively, were recovered (last BDI score <10). The dropout rate was significantly higher in CBT (40%; 19/47) compared to IPT (19%; 8/43). Statistically controlling for antidepressant medication use did not change the results. IPT was noninferior to CBT in a sample of depressed psychiatric patients in a community-based outpatient clinic. CBT had significantly more dropouts than IPT, indicating that CBT may be experienced as too demanding. Since about half the patients did not recover, there is a need for further treatment development for these patients. The study should be considered an effectiveness trial, with strong external validity but some limitations in internal validity. © 2016 Wiley Periodicals, Inc.

Complex posttraumatic stress disorder (Complex PTSD) has been recently proposed as a distinct clinical entity in the WHO International Classification of Diseases, 11 th version, due to be published, two decades after its first initiation. It is described as an enhanced version of the current definition of PTSD, with clinical features of PTSD plus three additional clusters of symptoms namely emotional dysregulation, negative self-cognitions and interpersonal hardship, thus resembling the clinical features commonly encountered in borderline personality disorder (BPD). Complex PTSD is related to complex trauma which is defined by its threatening and entrapping context, generally interpersonal in nature. In this manuscript, we review the current findings related to traumatic events predisposing the above-mentioned disorders as well as the biological correlates surrounding them, along with their clinical features. Furthermore, we suggest that besides the present distinct clinical diagnoses (PTSD; Complex PTSD; BPD), there is a cluster of these comorbid disorders, that follow a continuum of trauma and biological severity on a spectrum of common or similar clinical features and should be treated as such. More studies are needed to confirm or reject this hypothesis, particularly in clinical terms and how they correlate to clinical entities' biological background, endorsing a shift from the phenomenologically only classification of psychiatric disorders towards a more biologically validated classification.

Thorough review of current workload, staffing, and testing practices in clinical laboratories allows for optimization of laboratory efficiency and quality. This information is largely missing with regard to clinical flow cytometry laboratories. The purpose of this survey is to provide comprehensive, current, and accurate data on testing practices and laboratory staffing in clinical laboratories performing flow cytometric studies. Survey data was collected from flow cytometry laboratories through the ASCP website. Data was collected on the workload during a 1-year time period of full-time and part-time technical and professional (M.D./D.O./Ph.D. or equivalent) flow cytometry employees. Workload was examined as number of specimens and tubes per full time equivalent (FTE) technical and professional staff. Test complexity, test result interpretation, and reporting practices were also evaluated. There were 205 respondent laboratories affiliated predominantly with academic and health system institutions. Overall, 1,132 FTE employees were reported with 29% professional FTE employees and 71% technical. Fifty-one percent of the testing performed was considered high complexity and 49% was low complexity. The average number of tubes per FTE technologist was 1,194 per year and the average number of specimens per FTE professional was 1,659 per year. The flow cytometry reports were predominantly written by pathologists (57%) and were typically written as a separate report (58%). This survey evaluates the overall status of the current practice of clinical flow cytometry and provides a comprehensive dataset as a framework to help laboratory departments, directors, and managers make appropriate, cost-effective staffing decisions. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

The last decades of the 20th century were a period of outstanding scientific achievements. The most significant discovery was the decoding of the human genome (Venter, J. et al., 2001; Dennis, C. et al., 2001; Baltimore, D., 2001). In this article the present view of the post genomic era is presented. The new analytical methods, such as micro arrays, bio chips, and nano technology, the discovery of SNPs, and the analysis of the proteome will lead to a greater understanding of the pathogenesis of inherited and acquired diseases. Their use in clinical chemistry and laboratory medicine, and the future of technological innovations are discussed. In the post genomic era the greatest interest will be devoted to the application of these scientific achievements in the diagnosis, prevention and therapy of human diseases. The advances in human genetics that have occurred during the past 20 years have revolutionized our knowledge of the role played by inheritance in health and disease. It is clear that our DNA determines not only single gene disorders but also interacts with environments to predispose individuals to cancer, allergy, hypertension, heart disease, diabetes, psychiatric disorders and even to some infectious diseases. The study of longevity and the demonstration of genes favouring a long lifespan suggest that such protective systems exist. The study of genetic polymorphisms has made clear that some alleles have beneficial effects. These discoveries will be of great help in our understanding of the interactions between genetics and environment. Gene array analysis has become the method of choice for identifying genes expressed at different levels in different samples. The mRNA expression profiles of normal and tumor tissues, treated and untreated cell cultures, and developmental stages of an organism can be compared quickly and easily with an appropriate array analysis system. A major task after a genome has been fully sequenced is to understand the functions

Clinical laboratory procedure manuals are typically maintained as word processor files and are inefficient to store and search, require substantial effort for review and updating, and integrate poorly with other laboratory information. Electronic document management systems could improve procedure management and utility. As a first step toward building such systems, we have developed a prototype electronic format for laboratory procedures using Extensible Markup Language (XML). Representative laboratory procedures were analyzed to identify document structure and data elements. This information was used to create a markup vocabulary, CLP-ML, expressed as an XML Document Type Definition (DTD). To determine whether this markup provided advantages over generic markup, we compared procedures structured with CLP-ML or with the vocabulary of the Health Level Seven, Inc. (HL7) Clinical Document Architecture (CDA) narrative block. CLP-ML includes 124 XML tags and supports a variety of procedure types across different laboratory sections. When compared with a general-purpose markup vocabulary (CDA narrative block), CLP-ML documents were easier to edit and read, less complex structurally, and simpler to traverse for searching and retrieval. In combination with appropriate software, CLP-ML is designed to support electronic authoring, reviewing, distributing, and searching of clinical laboratory procedures from a central repository, decreasing procedure maintenance effort and increasing the utility of procedure information. A standard electronic procedure format could also allow laboratories and vendors to share procedures and procedure layouts, minimizing duplicative word processor editing. Our results suggest that laboratory-specific markup such as CLP-ML will provide greater benefit for such systems than generic markup.
Full Text Available Background. Huntington disease occurrs rarely, it can be encountered not only by neurologists and psychiatrists but also by other medical practitioners. Its characteristic features are involuntary movements, cognitive disorders and gradual development of dementia. Diagnosis is given on the basis of these clinical features, positive familial anamnesis, with the laboratory exclusion of other neuropsychiatric diseases and with the help of neuroimaging methods (in particular NMR. The disease can be only confirmed by means of genetic analysis.Patients and methods. In this article, four cases of patients with Huntington disease and diverse psychiatric disorders that were hospitalised at the psychiatric department of the Maribor General Hospital between October 2002 and March 2003 are described. All the patients fulfilled the valid criteria for the diagnosis of Huntington disease. However, they differed according to their accompanying psychiatric psychopathology, age and social problems.Conclusions. The purpose of this article is to draw attention to different psychiatric symptoms and clinical manifestations of Huntington disease that are often misleading in the diagnostic process. In addition, exigency of early diagnostics, guidelines for referrals to genetic testing and psychiatric monitoring of these patients are emphasised.
This article examines the case files of patients diagnosed with Transvestitismus [transvestism] in the Psychiatric Clinic of the Helsinki University Central Hospital in the years 1954–68. These individuals did not only want to cross-dress, but also had a strong feeling of being of a different sex from their assigned one. The scientific concept of transsexuality had begun to take form, and this knowledge reached Finland in phases. The case files of the transvestism patients show that they were highly aware of their condition and were very capable of describing it, even if they had no medical name for it. Psychiatrists were willing to engage in dialogue with the patients, and did not treat them as passive objects of study. Although some patients felt that they had been helped, many left the institution as frustrated, angered or desperate as before. They had sought medical help in the hope of having their bodies altered to correspond to their identity, but the Clinic psychiatrists insisted on seeing the problem in psychiatric terms and did not recommend surgical or hormonal treatments in most cases. This attitude would gradually change over the course of the 1970s and 1980s. PMID:29199927

The program of continuous quality improvement in clinical laboratory processes for complete blood count (CBC) was launched via the platform of Beijing Children's Hospital Group in order to improve the quality of pediatric clinical laboratories. Fifteen children's hospitals of Beijing Children's Hospital group were investigated using the method of Chinese adapted continuous quality improvement with PDCA (Plan-Do-Check-Action). The questionnaire survey and inter-laboratory comparison was conducted to find the existing problems, to analyze reasons, to set forth quality targets and to put them into practice. Then, targeted training was conducted to 15 children's hospitals and the second questionnaire survey, self examinations by the clinical laboratories was performed. At the same time, the Group's online internal quality control platform was established. Overall effects of the program were evaluated so that lay a foundation for the next stage of PDCA. Both quality of control system documents and CBC internal quality control scheme for all of clinical laboratories were improved through this program. In addition, standardization of performance verification was also improved, especially with the comparable verification rate of precision and internal laboratory results up to 100%. In terms of instrument calibration and mandatory diagnostic rates, only three out of the 15 hospitals (20%) failed to pass muster in 2014 from 46.67% (seven out of the 15 hospitals) in 2013. The abnormal data of intraday precision variance coefficients of the five CBC indicator parameters (WBC, RBC, Hb, Plt and Hct) of all the 15 laboratories accounted for 1.2% (2/165) in 2014, a marked decrease from 9.6% (14/145) in 2013. While the number of the hospitals using only one horizontal quality control object for daily quality control has dropped to three from five. The 15 hospitals organized a total of 263 times of training in 2014 from 101 times in 2013, up 160%. The quality improvement program for

The era of automation arrived with the introduction of the AutoAnalyzer using continuous flow analysis and the Robot Chemist that automated the traditional manual analytical steps. Successive generations of stand-alone analysers increased analytical speed, offered the ability to test high volumes of patient specimens, and provided large assay menus. A dichotomy developed, with a group of analysers devoted to performing routine clinical chemistry tests and another group dedicated to performing immunoassays using a variety of methodologies. Development of integrated systems greatly improved the analytical phase of clinical laboratory testing and further automation was developed for pre-analytical procedures, such as sample identification, sorting, and centrifugation, and post-analytical procedures, such as specimen storage and archiving. All phases of testing were ultimately combined in total laboratory automation (TLA) through which all modules involved are physically linked by some kind of track system, moving samples through the process from beginning-to-end. A newer and very powerful, analytical methodology is liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). LC-MS/MS has been automated but a future automation challenge will be to incorporate LC-MS/MS into TLA configurations. Another important facet of automation is informatics, including middleware, which interfaces the analyser software to a laboratory information systems (LIS) and/or hospital information systems (HIS). This software includes control of the overall operation of a TLA configuration and combines analytical results with patient demographic information to provide additional clinically useful information. This review describes automation relevant to clinical chemistry, but it must be recognised that automation applies to other specialties in the laboratory, e.g. haematology, urinalysis, microbiology. It is a given that automation will continue to evolve in the clinical laboratory

The Magenta Community Mental Health Centre (CMHC) is the public agency responsible for providing adult psychiatric care to about 85,000 adult residents. In 1995, it had 1,145 clients and incurred costs of Euro 1.9 millions. Average cost per patient and per adult resident were Euro 1,661 and Euro 22.2, respectively. These values mask large variation across diagnosis: while patients with schizophrenia and related disorders had an average cost of Euro 3,771, those with neurotic and related disorders had an average cost of Euro 439. Patients with schizophrenia and related disorders (28% of the patients) absorbed about 60% of total costs and made extensive use of several types of services (hospital, outpatient, domiciliary, social and rehabilitative care). Since integrating different types of services is the key element of Italian psychiatric care, the new fee-for-service system adopted by the NHS to fund providers does not appear appropriate, particularly for schizophrenic patients.

There is much uncertainty as to how fungal disease is diagnosed and characterized in patients with cystic fibrosis (CF). A 19-question anonymous electronic questionnaire was developed and distributed to ascertain current practice in clinical microbiology laboratories providing a fungal laboratory service to CF centres in the UK. Analyses of responses identified the following: (1) current UK laboratory practice, in general, follows the current guidelines, but the scope and diversity of what is currently being delivered by laboratories far exceeds what is detailed in the guidelines; (2) there is a lack of standardization of fungal tests amongst laboratories, outside of the current guidelines; (3) both the UK CF Trust Laboratory Standards for Processing Microbiological Samples from People with Cystic Fibrosis and the US Cumulative Techniques and Procedures in Clinical Microbiology (Cumitech) Guidelines 43 Cystic Fibrosis Microbiology need to be updated to reflect both new methodological innovations, as well as better knowledge of fungal disease pathophysiology in CF; (4) there is a need for clinical medicine to decide upon a stratification strategy for the provision of new fungal assays that will add value to the physician in the optimal management of CF patients; (5) there is also a need to rationale what assays should be performed at local laboratory level and those which are best served at National Mycology Reference Laboratory level; and (6) further research is required in developing laboratory assays, which will help ascertain the clinical importance of 'old' fungal pathogens, as well as 'emerging' fungal pathogens.

Quality indicators for assessing the performance of a laboratory require a systematic and continuous approach in collecting and analyzing data. The aim of this study was to determine the frequency of errors utilizing the quality indicators in a clinical chemistry laboratory and to convert errors to the Sigma scale. Five-year quality indicator data of a clinical chemistry laboratory was evaluated to describe the frequency of errors. An 'error' was defined as a defect during the entire testing process from the time requisition was raised and phlebotomy was done until the result dispatch. An indicator with a Sigma value of 4 was considered good but a process for which the Sigma value was 5 (i.e. 99.977% error-free) was considered well controlled. In the five-year period, a total of 6,792,020 specimens were received in the laboratory. Among a total of 17,631,834 analyses, 15.5% were from within hospital. Total error rate was 0.45% and of all the quality indicators used in this study the average Sigma level was 5.2. Three indicators - visible hemolysis, failure of proficiency testing and delay in stat tests - were below 5 on the Sigma scale and highlight the need to rigorously monitor these processes. Using Six Sigma metrics quality in a clinical laboratory can be monitored more effectively and it can set benchmarks for improving efficiency.

Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease, which is usually transmitted to humans by tick bites or contact with blood or other infected tissues of livestock. Patients suffering from CCHF demonstrate an extensive spectrum of clinical symptoms. As it can take considerable time from suspecting the disease in hospital until reaching a definitive diagnosis in the laboratory, understanding the clinical symptoms and laboratory findings of CCHF patients is of paramount importance for clinicians. The data were collected from patients who were referred to the Laboratory of Arboviruses and Viral Hemorrhagic Fevers at the Pasteur institute of Iran with a primary diagnosis of CCHF between 1999 and 2012 and were assessed by molecular and serologic tests. Referred patients were divided into two groups: patients with a CCHF positive result and patients with a CCHF negative result. The laboratory and clinical findings of these two groups were then compared. Two-thousand five hundred thirty-six probable cases of CCHF were referred to the laboratory, of which 871 cases (34.3%) were confirmed to be CCHF. Contact with infected humans and animals increased the CCHF infection risk (P important role in patient survival and the application of the findings of this study can prove helpful as a key for early diagnosis. © 2014 Wiley Periodicals, Inc.

Patient care relies heavily on standardized tests performed in hospital laboratories, typically including clinical chemistry, pathology and microbiology. With the introduction of personalized medicine tremendous efforts have been made to identify new biomarkers of disease with various omics technologies, often including mass spectrometry. In order to validate new biomarkers and perform clinical studies high quality biobank samples are of key importance. In this editorial different aspects of mass spectrometry in future personalized medicine are discussed.

Conclusions: Lethargy, abdominal distension, pleural effusion, and hypoalbuminemia were the best clinical and laboratorial markers of serious dengue disease in hospitalized children, while bleeding, severe hemorrhage, hemoconcentration and thrombocytopenia did not reach adequate diagnostic accuracy. In pediatric referral hospitals, the absence of hemoconcentration does not imply absence of plasma leakage, particularly in children with previous fluid replacement. These findings may contribute to the clinical management of dengue in children at referral hospitals.

Clinical microbiology and public health laboratories are beginning to utilize next-generation sequencing (NGS) for a range of applications. This technology has the potential to transform the field by providing approaches that will complement, or even replace, many conventional laboratory tests. While the benefits of NGS are significant, the complexities of these assays require an evolving set of standards to ensure testing quality. Regulatory and accreditation requirements, professional guidelines, and best practices that help ensure the quality of NGS-based tests are emerging. This review highlights currently available standards and guidelines for the implementation of NGS in the clinical and public health laboratory setting, and it includes considerations for NGS test validation, quality control procedures, proficiency testing, and reference materials.

The authors have experimented the application of the Failure Mode and Effect Analysis (FMEA) technique in a clinical laboratory. FMEA technique allows: a) to evaluate and measure the hazards of a process malfunction, b) to decide where to execute improvement actions, and c) to measure the outcome of those actions. A small sample of analytes has been studied: there have been determined the causes of the possible malfunctions of the analytical process, calculating the risk probability index (RPI), with a value between 1 and 1,000. Only for the cases of RPI > 400, improvement actions have been implemented that allowed a reduction of RPI values between 25% to 70% with a costs increment of FMEA technique can be applied to the processes of a clinical laboratory, even if of small dimensions, and offers a high potential of improvement. Nevertheless, such activity needs a thorough planning because it is complex, even if the laboratory already operates an ISO 9000 Quality Management System.

Several countries have in recent years introduced prescribed requirements for treatment and monitoring of outcomes, as well as a licensing or accreditation requirement for in vitro fertilization (IVF) clinics and their laboratories. It is commonplace for Assisted Reproductive Technology (ART) laboratories to be required to have a quality control system. However, more effective Total Quality Management systems are now being implemented by an increasing number of ART clinics. In India, it is now a requirement to have a quality management system in order to be accredited and to help meet customer demand for improved delivery of ART services. This review contains the proceedings a quality management session at the Indian Fertility Experts Meet (IFEM) 2010 and focuses on the creation of a patient-oriented best-in-class IVF laboratory.

This study evaluated the relationship between 111 In-labeled leukocyte scintigraphy and clinical information and laboratory findings in 24 patients with bone infection and 35 patients with abdominal infection. Fifty-nine scintigrams were retrospectively reviewed and classified into positive or negative results. As the laboratory findings, C-reactive protein (CRP) level, erythrocyte sedimentation rate (ESR) at 60 minutes, and peripheral blood leukocyte counts (WBCC) were evaluated. Clinical information such as presence of fever and administration of antibiotics was also compared. No significant relationship between the scintigraphic results and clinical as well as laboratory findings was observed in bone infection patients. CRP levels in positive scintigraphic patients were significantly higher than those in negative scintigraphic patients in the abdominal infection group, otherwise the other indices were not correlated with the scintigraphic results. A few patients with slightly increased CRP (mostly chronic cases) did not show positive scintigrams, suggesting an increased false negative rate of leukocyte scintigraphy in such circumstances. These results suggest that it is inappropriate to determine the application of leukocyte scintigraphy depending on clinical as well as laboratory findings, and leukocyte scintigraphy would yield additional information different from other indices when evaluating inflammatory foci.

To face the economic pressures arising from the current socio-economic conjuncture, hospital laboratories are endangered by an increasing trend towards the outsourcing of clinical laboratory tests to external (mega-) laboratories. This should allow hospitals to meet their economic requirements, but with an increased risk of loss of medical quality and, mid- to long-term, loss of cost effectiveness of healthcare at the national level. To anticipate current developments (economical and technological) that inevitably will affect the future of laboratory medicine, hospital laboratories should be proactive and enhance efficiency, reduce costs by consolidation, integrate into regional networks, and form alliances or partnerships. To create additional value, the core competency of laboratory professionals must be refocused to provide medical knowledge services (consultative support to clinicians) related to in vitro diagnostic testing. To integrate cost-efficiency with medical quality, implementation of a matricial organization - operational vs. biomedical level - could be an interesting approach. This integrated structure should create total quality of laboratory testing, managing the entire medical diagnostic cycle from the pre-preanalytical to post-postanalytical phase.

Patient Safety Monitoring in International Laboratories (JHU-SMILE) is a resource at Johns Hopkins University that supports and monitors laboratories in National Institutes of Health-funded international clinical trials. To determine the impact of the JHU-SMILE quality assurance scheme in sub-Saharan African laboratories, we reviewed 40 to 60 months of external quality assurance (EQA) results of the College of American Pathologists (CAP) in these laboratories. We reviewed the performance of 8 analytes: albumin, alanine aminotransferase, creatinine, sodium, WBC, hemoglobin, hematocrit, and the human immunodeficiency virus antibody rapid test. Over the 40- to 60-month observation period, the sub-Saharan laboratories had a 1.63% failure rate, which was 40% lower than the 2011 CAP-wide rate of 2.8%. Seventy-six percent of the observed EQA failures occurred in 4 of the 21 laboratories. These results demonstrate that a system of remote monitoring, feedback, and audits can support quality in low-resource settings, even in places without strong regulatory support for laboratory quality.

Despite the fact that Ethiopia has scale up antiretroviral treatment (ART) program, little is known about the patient satisfaction with ART monitoring laboratory services in health facilities. We therefore aimed to assess patient satisfaction with laboratory services at ART clinics in public hospitals. Hospital based, descriptive cross sectional study was conducted from October to November 2010 among clients attending in nine public hospitals ART clinics in Addis Ababa Ethiopia. Patients' satisfaction towards laboratory services was assessed using exit interview structured questionnaire. Data were coded and entered using EPI info 2002 (Centers for Disease Control and Prevention Atlanta, GA) and analyzed using SPSS version 15 software (SPSS INC, Chicago, IL, USA). A total of 406 clients were involved in the study. Of these 255(62.8%) were females. The overall satisfaction rate for ART monitoring laboratory services was (85.5%). Patients were satisfied with measures taken by health care providers to keep confidentiality and ability of the person drawing blood to answer question (98.3% and 96.3% respectively). Moreover, the finding of this study revealed, statistical significant associations between the overall patients' satisfaction with waiting time to get blood drawing service, availability of ordered laboratory tests and waiting time to get laboratory result with (p ART monitoring laboratory services compared to those who underwent for more than 30 minutes. Overall, the satisfaction survey showed, most respondents were satisfied with ART monitoring laboratory services. However, factors such as improving accessibility and availability of latrines should be taken into consideration in order to improve the overall satisfaction.

Background Despite advances in clinical chemistry testing, poor blood sample quality continues to impact laboratory operations and the quality of results. While previous studies have identified the preanalytical causes of lower sample quality, few studies have examined the economic impact of poor sample quality on the laboratory. Specifically, the costs associated with workarounds related to fibrin and gel contaminants remain largely unexplored. Methods A quantitative survey of clinical chemistry laboratory stakeholders across 10 international regions, including countries in North America, Europe and Oceania, was conducted to examine current blood sample testing practices, sample quality issues and practices to remediate poor sample quality. Survey data were used to estimate costs incurred by laboratories to mitigate sample quality issues. Results Responses from 164 participants were included in the analysis, which was focused on three specific issues: fibrin strands, fibrin masses and gel globules. Fibrin strands were the most commonly reported issue, with an overall incidence rate of ∼3%. Further, 65% of respondents indicated that these issues contribute to analyzer probe clogging, and the majority of laboratories had visual inspection and manual remediation practices in place to address fibrin- and gel-related quality problems (55% and 70%, respectively). Probe maintenance/replacement, visual inspection and manual remediation were estimated to carry significant costs for the laboratories surveyed. Annual cost associated with lower sample quality and remediation related to fibrin and/or gel globules for an average US laboratory was estimated to be $100,247. Conclusions Measures to improve blood sample quality present an important step towards improved laboratory operations.

Among National Institutes of Health HIV Research Networks conducting multicenter trials, samples from protocols that span several years are analyzed at multiple clinical pharmacology laboratories (CPLs) for multiple antiretrovirals. Drug assay data are, in turn, entered into study-specific data sets that are used for pharmacokinetic analyses, merged to conduct cross-protocol pharmacokinetic analysis, and integrated with pharmacogenomics research to investigate pharmacokinetic-pharmacogenetic associations. The CPLs participate in a semiannual proficiency testing (PT) program implemented by the Clinical Pharmacology Quality Assurance program. Using results from multiple PT rounds, longitudinal analyses of recovery are reflective of accuracy and precision within/across laboratories. The objectives of this longitudinal analysis of PT across multiple CPLs were to develop and test statistical models that longitudinally: (1) assess the precision and accuracy of concentrations reported by individual CPLs and (2) determine factors associated with round-specific and long-term assay accuracy, precision, and bias using a new regression model. A measure of absolute recovery is explored as a simultaneous measure of accuracy and precision. Overall, the analysis outcomes assured 97% accuracy (±20% of the final target concentration of all (21) drug concentration results reported for clinical trial samples by multiple CPLs). Using the Clinical Laboratory Improvement Act acceptance of meeting criteria for ≥2/3 consecutive rounds, all 10 laboratories that participated in 3 or more rounds per analyte maintained Clinical Laboratory Improvement Act proficiency. Significant associations were present between magnitude of error and CPL (Kruskal-Wallis P Kruskal-Wallis P < 0.001).

Strengthening national health laboratory systems in resource-poor countries is critical to meeting the United Nations Millennium Development Goals. Despite strong commitment from the international community to fight major infectious diseases, weak laboratory infrastructure remains a huge rate-limiting step. Some major challenges facing laboratory systems in resource-poor settings include dilapidated infrastructure; lack of human capacity, laboratory policies, and strategic plans; and limited synergies between clinical and research laboratories. Together, these factors compromise the quality of test results and impact patient management. With increased funding, the target of laboratory strengthening efforts in resource-poor countries should be the integrating of laboratory services across major diseases to leverage resources with respect to physical infrastructure; types of assays; supply chain management of reagents and equipment; and maintenance of equipment.

We report a first randomized clinical trial examining the effect of immediate and non-immediate therapist self-disclosure in the context of a brief integrative psychotherapy for mild to moderate distress. A total of 86 patients with mild to moderate forms of distress were randomly divided into three 12-session integrative psychotherapy conditions based primarily on [Hill, C. E. (2009). Helping skills: Facilitating, exploration, insight, and action (3rd ed.). Washington, DC: American Psychological Association.] three-stage model. Therapists trained in this treatment modality were instructed to use either immediate self-disclosure (expressing feelings towards the patient/treatment/therapeutic relationship) or non-immediate self-disclosure (expressing personal or factual information regarding the therapist's life outside the treatment). In the comparison condition, the therapists were instructed to refrain from self-disclosure altogether. Immediate therapist self-disclosure reduced psychiatric symptoms among patients with elevated pretreatment symptoms (as assessed by the Brief Symptoms Inventory) and bolstered a favorable perception of the therapist. Therapists in both the immediate and non-immediate self-disclosure group evaluated themselves more favorably than their counterparts in the non-disclosure group. Therapist self-disclosure, particularly of the immediate type, might enhance the effect of brief integrative treatment on psychiatric symptoms of high symptomatic patients and contribute to favorable perception of therapists.

The diagnosis of infectious diseases and the role of the microbiology laboratory are currently undergoing a process of change. The need for overall efficiency in providing results is now given the same importance as accuracy. This means that laboratories must be able to produce quality results in less time with the capacity to interpret the results clinically. To improve the clinical impact of microbiology results, the new challenge facing the microbiologist has become one of process management instead of pure analysis. A proper project management process designed to improve workflow, reduce analytical time, and provide the same high quality results without losing valuable time treating the patient, has become essential. Our objective was to study the impact of introducing automation and computerization into the microbiology laboratory, and the reorganization of the laboratory workflow, i.e. scheduling personnel to work shifts covering both the entire day and the entire week. In our laboratory, the introduction of automation and computerization, as well as the reorganization of personnel, thus the workflow itself, has resulted in an improvement in response time and greater efficiency in diagnostic procedures.

Organizing work flow is a major task of laboratory management. Recently, clinical laboratories have started to adopt methodologies such as Lean Six Sigma and some successful implementations have been reported. This study used Lean Six Sigma to simplify the laboratory work process and decrease the turnaround time by eliminating non-value-adding steps. The five-stage Six Sigma system known as define, measure, analyze, improve, and control (DMAIC) is used to identify and solve problems. The laboratory turnaround time for individual tests, total delay time in the sample reception area, and percentage of steps involving risks of medical errors and biological hazards in the overall process are measured. The pre-analytical process in the reception area was improved by eliminating 3 h and 22.5 min of non-value-adding work. Turnaround time also improved for stat samples from 68 to 59 min after applying Lean. Steps prone to medical errors and posing potential biological hazards to receptionists were reduced from 30% to 3%. Successful implementation of Lean Six Sigma significantly improved all of the selected performance metrics. This quality-improvement methodology has the potential to significantly improve clinical laboratories. © 2017 Wiley Periodicals, Inc.

management challenges of clinical laboratories are more complicated for educational hospital clinical laboratories. Managers can use tools of business intelligence (BI), such as information dashboards that provide the possibility of intelligent decision-making and problem solving about increasing income, reducing spending, utilization management and even improving quality. Critical phase of dashboard design is setting indicators and modeling causal relations between them. The paper describes the process of creating a map for laboratory dashboard. the study is one part of an action research that begins from 2012 by innovation initiative for implementing laboratory intelligent dashboard. Laboratories management problems were determined in educational hospitals by the brainstorming sessions. Then, with regard to the problems key performance indicators (KPIs) specified. the map of indicators designed in form of three layered. They have a causal relationship so that issues measured in the subsequent layers affect issues measured in the prime layers. the proposed indicator map can be the base of performance monitoring. However, these indicators can be modified to improve during iterations of dashboard designing process.

The organization of public clinical laboratories is experiencing changes without, however, an organizational assessment of its effectiveness. The study aimed to determine a parameter of effectiveness for public clinical laboratories of Belo Horizonte, Minas Gerais State, and set cut-off points for the sections of these laboratories. In order to do so, the total production and number of hours worked during a period of 7 months in the year 2008 were consolidated. Due to the entrance of the workers in the mode of production in the laboratories network, it could be observed a variability regarding the performance of these workers. The effectiveness parameter of the network was established in 29.90 tests per hour. As a consequence of this first analysis, the cut-off points are: 15.50 for the hematology section; 67.29 for chemistry; 6.45 for parasitology; 11.35 for urinalysis; 4.94 for microbiology and 19.03 for immunology. From these results, it was concluded that the working process in laboratories can generate a decrease in effectiveness.
Full Text Available Abstract Background In the Swedish society, as in many other societies, many children and adolescents with mental health problems do not receive the help they need. As the Swedish society becomes increasingly multicultural, and as ethnic and economic residential segregation become more pronounced, this study utilises ethnicity and neighbourhood context to examine referral pathways to child and adolescent psychiatric (CAP clinics. Methods The analysis examines four different sources of referrals: family referrals, social/legal agency referrals, school referrals and health/mental health referrals. The referrals of 2054 children aged 11-19 from the Stockholm Child-Psychiatric Database were studied using multilevel logistic regression analyses. Results Results indicate that ethnicity played an important role in how children and adolescents were referred to CAP-clinics. Family referrals were more common among children and adolescents with a Swedish background than among those with an immigrant background. Referrals by social/legal agencies were more common among children and adolescents with African and Asian backgrounds. Children with Asian or South American backgrounds were more likely to have been referred by schools or by the health/mental health care sector. A significant neighbourhood effect was found in relation to family referrals. Children and adolescents from neighbourhoods with low levels of socioeconomic deprivation were more likely to be referred to CAP-clinics by their families in comparison to children from other neighbourhoods. Such differences were not found in relation in relation to the other sources of referral. Conclusions This article reports findings that can be an important first step toward increasing knowledge on reasons behind differential referral rates and uptake of psychiatric care in an ethnically diverse Swedish sample. These findings have implications for the design and evaluation of community mental health outreach

We conducted a questionnaire survey regarding the current activities for protecting patients' privacy and the security of information systems (IS) related to the clinical laboratory departments of university hospitals, certified training facilities for clinical laboratories, and general hospitals in Yamaguchi Prefecture. The response rate was 47% from 215 medical institutions, including three commercial clinical laboratory centers. The results showed that there were some differences in management activities among facilities with respect to continuing education, the documentation or regulation of operational management for paper records, electronic information, remaining samples, genetic testing, and laboratory information for secondary use. They were suggested to be caused by differences in functions between university and general hospitals, differences in the scale of hospitals, or whether or not hospitals have received accreditation or ISO 15189. Regarding the IS, although the majority of facilities had sufficiently employed the access control to IS, there was some room for improvement in the management of special cases such as VIPs and patients with HIV infection. Furthermore, there were issues regarding the login method for computers shared by multiple staff, the showing of the names of personnel in charge of reports, and the risks associated with direct connections to systems and the Internet and the use of portable media such as USB memory sticks. These results indicated that further efforts are necessary for each facility to continue self-assessment and make improvements.

To cope with the government's policies to reduce medical costs, Taiwan's healthcare service providers are striving to survive by pursuing profit maximization through cost control. This article aimed to present the results of cost evaluation using activity-based costing performed in the laboratory in order to throw light on the differences between costs and the payment system of National Health Insurance (NHI). This study analyzed the data of costs and income of the clinical laboratory. Direct costs belong to their respective sections of the department. The department's shared costs, including public expenses and administrative assigned costs, were allocated to the department's respective sections. A simple regression equation was created to predict profit and loss, and evaluate the department's break-even point, fixed cost, and contribution margin ratio. In clinical chemistry and seroimmunology sections, the cost per test was lower than the NHI payment and their major laboratory tests had revenues with the profitability ratio of 8.7%, while the other sections had a higher cost per test than the NHI payment and their major tests were in deficit. The study found a simple linear regression model as follows: "Balance=-84,995+0.543×income (R2=0.544)". In order to avoid deficit, laboratories are suggested to increase test volumes, enhance laboratory test specialization, and become marginal scale. A hospital could integrate with regional medical institutions through alliances or OEM methods to increase volumes to reach marginal scale and reduce laboratory costs, enhancing the level and quality of laboratory medicine.

Full Text Available Determining the cause of psychiatric disorders is a goal of modern neuroscience, and will hopefully lead to the discovery of treatments to either prevent or alleviate the suffering caused by these diseases. One roadblock to attaining this goal is the realization that neuropsychiatric diseases are rarely due to a single gene polymorphism, environmental exposure, or developmental insult. Rather, it is a complex interaction between these various influences that likely leads to the development of clinically relevant syndromes. Our lab is exploring the links between environmental exposures and neurobehavioral function by investigating how disruption of the circadian (daily clock alters the structure and function of neural circuits, with the hypothesis that disrupting this crucial homeostatic system can directly contribute to altered vulnerability of the organism to other factors that interact to produce psychiatric illness. This review explores some historical and more recent findings that link disrupted circadian clocks to neuropsychiatric disorders, particularly depression, mania, and schizophrenia. We take a comparative approach by exploring the effects observed in human populations, as well as some experimental models used in the laboratory to unravel mechanistic and causal relationships between disruption of the circadian clock and behavioral abnormalities. This is a rich area of research that we predict will contribute greatly to our understanding of how genes, environment, and development interact to modulate an individual’s vulnerability to psychiatric disorders.

Timely delivery of correct results has long been considered as the goal of quality management in clinical laboratory. With increasing workload as well as complexities of laboratory testing and patient care, the traditional technical adopted like internal quality control (IQC) and external quality assessment (EQA) may not enough to cope with quality management problems for clinical laboratories. We applied failure mode and effects analysis (FMEA), a proactive tool, to reduce errors associated with the process beginning with sample collection and ending with a test report in a clinical chemistry laboratory. Our main objection was to investigate the feasibility of FMEA in a real-world situation, namely the working environment of hospital. A team of 8 people (3 laboratory workers, 2 couriers, 2 nurses, and 1 physician) from different departments who were involved in the testing process were recruited and trained. Their main responsibility was to analyze and score all possible clinical chemistry laboratory failures based on three aspects: the severity of the outcome (S), the likeliness of occurrence (O), and the probability of being detected (D). These three parameters were multiplied to calculate risk priority numbers (RPNs), which were used to prioritize remedial measures. Failure modes with RPN≥200 were deemed as high risk, meaning that they needed immediate corrective action. After modifications that were put, we compared the resulting RPN with the previous one. A total of 33 failure modes were identified. Many of the failure modes, including the one with the highest RPN (specimen hemolysis) appeared in the pre-analytic phase, whereas no high-risk failure modes (RPN≥200) were found during the analytic phase. High-priority risks were "sample hemolysis" (RPN, 336), "sample delivery delay" (RPN, 225), "sample volume error" (RPN, 210), "failure to release results in a timely manner" (RPN, 210), and "failure to identify or report critical results" (RPN, 200).

A retrospective chart review of the clinical and psychosocial profile of psychotic adolescents with co-morbid substance use disorders presenting to acute adolescent psychiatric services at Tygerberg Hospital
Full Text Available Background. A large number of adolescents meet criteria for ‘dual diagnosis’ (a psychiatric disorder plus co-morbid substance use disorder (SUD, which prolongs treatment response and complicates intervention strategies. The current service model in Cape Town divides the care of such patients into psychiatric treatment and a separate substance use intervention. Child and adolescent mental health services face the challenge of high rates of readmission of adolescents into psychiatric facilities before utilisation of community-based substance abuse services. Objective. There is a scarcity of available treatment guidelines for dual-diagnosis adolescents, and a lack of systematically documented epidemiological and clinical data in South African adolescent populations. Method. A retrospective chart review of adolescent psychiatric admissions to the Tygerberg Adolescent Psychiatric Unit during 2010 was conducted. Relevant epidemiological, clinical and demographic data for those presenting with a dual diagnosis (specifically psychotic disorders and SUD was recorded. Results. Results suggest a high prevalence of SUD among adolescents presenting with a first-episode psychosis. Statistically significant correlations with lower levels of education were found in those with ongoing substance abuse (specifically cannabis and methamphetamine, and a significant relationship between choice of debut drug and ongoing drug use was also demonstrated. Risk factors for SUD (psychosocial adversities, childhood trauma, family and community exposure to substances, early debut drug ages, risky sexual behaviours, and clinical psychiatric profiles of adolescents with dual diagnosis are described. Conclusions. This cohort had an enhanced risk as a result of genetic vulnerability and environmental availability of substances, and the findings emphasise the differences in presentation, choice of drugs of abuse and psychosocial difficulties of adolescents with a dual

Full Text Available Abstract Background The diagnosis of malaria can be difficult in non-endemic areas, such as the United States, and delays in diagnosis and errors in treatment occur too often. Methods A nationwide survey of laboratories in the United States and its nine dependent territories was conducted in 2010 to determine factors that may contribute to shortcomings in the diagnosis of malaria. This survey explored the availability of malaria diagnostic tests, techniques used, and reporting practices. Results The survey was completed by 201 participants. Ninety percent reported that their laboratories had at least one type of malaria diagnostic test available on-site. Nearly all of the respondents' laboratories performed thick and thin smears on-site; approximately 50% had access to molecular testing; and only 17% had access to rapid diagnostic tests on-site. Seventy-three percent reported fewer than five confirmed cases of malaria in their laboratory during the 12-month period preceding the survey. Twenty-eight percent stated that results of species identification took more than 24 hours to report. Only five of 149 respondents that performed testing 24 hours a day, 7 days a week complied with all of the Clinical and Laboratory Standards Institute (CLSI guidelines for analysis and reporting of results. Conclusion Although malaria diagnostic testing services were available to a majority of U.S. laboratories surveyed, very few were in complete compliance with all of the CLSI guidelines for analysis and reporting of results, and most respondents reported very few cases of malaria annually. Laboratories' difficulty in adhering to the rigorous CLSI guidelines and their personnel's lack of practice and proficiency may account for delays and errors in diagnosis. It is recommended that laboratories that infrequently process samples for malaria seek opportunities for practice and proficiency training annually and take advantage of available resources to assist in

There is increasing pressure to provide cost-effective healthcare based on “best practice.” Consequently, new biomarkers are only likely to be introduced into routine clinical biochemistry departments if they are supported by a strong evidence base and if the results will improve patient management and outcome. This requires convincing evidence of the benefits of introducing the new test, ideally reflected in fewer hospital admissions, fewer additional investigations and/or fewer clinic visits. Carefully designed audit and cost-benefit studies in relevant patient groups must demonstrate that introducing the biomarker delivers an improved and more effective clinical pathway. From the laboratory perspective, pre-analytical requirements must be thoroughly investigated at an early stage. Good stability of the biomarker in relevant physiological matrices is essential to avoid the need for special processing. Absence of specific timing requirements for sampling and knowledge of the effect of medications that might be used to treat the patients in whom the biomarker will be measured is also highly desirable. Analytically, automation is essential in modern high-throughput clinical laboratories. Assays must therefore be robust, fulfilling standard requirements for linearity on dilution, precision and reproducibility, both within- and between-run. Provision of measurements by a limited number of specialized reference laboratories may be most appropriate, especially when a new biomarker is first introduced into routine practice. PMID:21137030

Full Text Available A clinical and laboratory evaluation of 11 children and young adults with measleslike rash was done during the measles outbreak in the Greater São Paulo Metropolitan area at the end of 1996 and spread over the country during 1997. Measles was laboratory confirmed in 07 patients by specific IgM detection in acute serum specimens using an IgM-capture EIA, by specific IgG seroconversion in serum pairs, and by reverse transcription PCR and virus isolation in peripheral blood lymphocytes. Clinical presentations were not always classic; one of the 07 cases had received measles vaccine and corresponded to modified clinical case of measles. The 4 remaining cases were negative for measles and were diagnosed as exanthem subitum (2 cases, scarlet fever and Kawasaki disease. The present study reinforces the view that clinical features alone are not sufficient for establishing an accurate diagnosis in the post-vaccine era, and a surveillance system based on sensitive laboratory results is needed so that it can confirm IgM-negative measles cases.

Full Text Available Background: Autoverification is a process of using computer-based rules to verify clinical laboratory test results without manual intervention. To date, there is little published data on the use of autoverification over the course of years in a clinical laboratory. We describe the evolution and application of autoverification in an academic medical center clinical chemistry core laboratory. Subjects and Methods: At the institution of the study, autoverification developed from rudimentary rules in the laboratory information system (LIS to extensive and sophisticated rules mostly in middleware software. Rules incorporated decisions based on instrument error flags, interference indices, analytical measurement ranges (AMRs, delta checks, dilution protocols, results suggestive of compromised or contaminated specimens, and ′absurd′ (physiologically improbable values. Results: The autoverification rate for tests performed in the core clinical chemistry laboratory has increased over the course of 13 years from 40% to the current overall rate of 99.5%. A high percentage of critical values now autoverify. The highest rates of autoverification occurred with the most frequently ordered tests such as the basic metabolic panel (sodium, potassium, chloride, carbon dioxide, creatinine, blood urea nitrogen, calcium, glucose; 99.6%, albumin (99.8%, and alanine aminotransferase (99.7%. The lowest rates of autoverification occurred with some therapeutic drug levels (gentamicin, lithium, and methotrexate and with serum free light chains (kappa/lambda, mostly due to need for offline dilution and manual filing of results. Rules also caught very rare occurrences such as plasma albumin exceeding total protein (usually indicative of an error such as short sample or bubble that evaded detection and marked discrepancy between total bilirubin and the spectrophotometric icteric index (usually due to interference of the bilirubin assay by immunoglobulin (Ig M monoclonal

Infectious mononucleosis (IM) or Mononucleosis syndrome is caused by an acute infection of Epstein-Barr virus. In Latin American countries, there are little information pertaining to the clinical manifestations and complications of this disease. For this reason, the purpose of this work was to describe the clinical and laboratory characteristics of infection by Epstein-Barr virus in Mexican children with infectious mononucleosis. A descriptive study was carried out by reviewing the clinical files of patients less than 18 years old with clinical and serological diagnosis of IM by Epstein-Barr virus from November, 1970 to July, 2011 in a third level pediatric hospital in Mexico City. One hundred and sixty three cases of IM were found. The most frequent clinical signs were lymphadenopathy (89.5%), fever (79.7%), general body pain (69.3%), pharyngitis (55.2%), hepatomegaly (47.2%). The laboratory findings were lymphocytosis (41.7%), atypic lymphocytes (24.5%), and increased transaminases (30.9%), there were no rupture of the spleen and no deaths among the 163 cases. Our results revealed that IM appeared in earlier ages compared with that reported in industrialized countries, where adolescents are the most affected group. Also, the order and frequency of the clinical manifestations were different in our country than in industrialized ones.

The aim of this study is to determine inter-laboratory variability on embryo assessment using time-lapse platform and conventional morphological assessment. This study compares the data obtained from a pilot study of external quality control (EQC) of time lapse, performed in 2014, with the classical EQC of the Spanish Society for the Study of Reproductive Biology (ASEBIR) performed in 2013 and 2014. In total, 24 laboratories (8 using EmbryoScope™, 15 using Primo Vision™ and one with both platforms) took part in the pilot study. The clinics that used EmbryoScope™ analysed 31 embryos and those using Primo Vision™ analysed 35. The classical EQC was implemented by 39 clinics, based on an analysis of 25 embryos per year. Both groups were required to evaluate various qualitative morphological variables (cell fragmentation, the presence of vacuoles, blastomere asymmetry and multinucleation), to classify the embryos in accordance with ASEBIR criteria and to stipulate the clinical decision taken. In the EQC time-lapse pilot study, the groups were asked to determine, as well as the above characteristics, the embryo development times, the number, opposition and size of pronuclei, the direct division of 1 into 3 cells and/or of 3 into 5 cells and false divisions. The degree of agreement was determined by calculating the intra-class correlation coefficients and the coefficient of variation for the quantitative variables and the Gwet index for the qualitative variables. For both EmbryoScope™ and Primo Vision™, two periods of greater inter-laboratory variability were observed in the times of embryo development events. One peak of variability was recorded among the laboratories addressing the first embryo events (extrusion of the second polar body and the appearance of pronuclei); the second peak took place between the times corresponding to the 8-cell and morula stages. In most of the qualitative variables analysed regarding embryo development, there was almost

Until the mid-1960s the nonhospital clinical laboratory industry was dominated by pathologists. The ethics of medical professionalism protected the pathologists' market from price competition and from any serious threat from new entrants into the market. Immune from the competitive pressures of the marketplace, pathologists exerted monopoly control in local markets. That power was eroded by laboratories operated by technologists and bioanalysts and was finally overcome by the entry of large corporations into the industry. The market power of the largest corporate laboratories is now growing to a point where competition may again be thwarted. The professional ethics of pathologists allowed high prices, but there was little push toward higher volume. The commercial ethics of the corporate entrants brought lower prices but resulted in strong pressure for greater test quantities. In either case, the power wielded by the dominant producer would seem to go against the consumer's interests.

The interpretation and the accuracy of the microbiological results still depend to a great extent on the quality of the samples and their processing within the Microbiology laboratory. The type of specimen, the appropriate time to obtain the sample, the way of sampling, the storage and transport are critical points in the diagnostic process. The availability of new laboratory techniques for unusual pathogens, makes necessary the review and update of all the steps involved in the processing of the samples. Nowadays, the laboratory automation and the availability of rapid techniques allow the precision and turn-around time necessary to help the clinicians in the decision making. In order to be efficient, it is very important to obtain clinical information to use the best diagnostic tools.

The Multidimensional Inventory for Religious/Spiritual Well-Being (MI-RSWB) was successfully applied in several clinical as well as non-clinical studies. However, the original version of the scale often showed to be as too comprehensive especially for clinical surroundings. There for the aim of this study is to develop a short version of the scale comprising 12 items. Based on a sample representative of the Austrian general population (N = 1,500), a first MI-RSWB short version is developed by means of factor- and reliability analysis. Furthermore the new short version of the scale is initially validated through several indicators of mental illness. The MI-RSWB short version shows convincing psychometric properties. The total scale as well as the sub scales exhibit at least a sufficient internal consistency. A significant negative association with several indicators of psychiatric illness is also confirmed for the short version of the scale. The MI-RWSB 12 scale is especially recommended for further research focusing on the clinical relevance of religiosity and spirituality.

BACKGROUND Since 1989, several investigators have reported unusual cases of severe opportunistic infections associated with CD4 lymphocytopenia in the absence of human immunodeficiency virus infection. The cause of this condition is unknown. The Centres for Disease Control and Prevention (CDC) defines Idiopathic CD4 T Lymphocytopenia (ICL) as a clinical condition in which patients with depressed numbers of circulating CD4+ T-cell lymphocytes (

As with many studies carried out in European countries, a quality assurance program has been established by the National Center for Clinical Laboratories in China (NCCL). The results showed that the external quality assessment significantly improves laboratory performance for quantitative evaluation of hepatitis C virus (HCV) RNA. Serum panels were delivered twice annually to the clinical laboratories which performed HCV RNA detection in China. Each panel made up of 5 coded samples. All laboratories were requested to carry out the detection within the required time period and report on testing results which contained qualitative and/or quantitative test findings, reagents used and relevant information about apparatus. All the positive samples were calibrated against the first International Standard for HCV RNA in a collaborative study and the range of comparison target value (TG) designated as +/- 0.5 log. The numbers of laboratories reporting on qualitative testing results for the first and second time external quality assessment were 168 and 167 in the year of 2003 and increased to 209 and 233 in 2007; the numbers of laboratories reporting on quantitative testing results were 134 and 147 in 2003 and rose to 340 and 339 in 2007. Deviation between the mean value for quantitative results at home in 2003 and the target value was above 0.5 log, which was comparatively high. By 2007, the target value was close to the national average except for the low concentrated specimens (10(3) IU/ml). The percentage of results within the range of GM +/- 0.5 log(10) varied from 8.2% to 93.5%. Some laboratories had some difficulties in the exact quantification of the lowest (3.00 log IU/ml) as well as of the highest viral levels (6.37 log IU/ml) values, very near to the limits of the dynamic range of the assays. The comparison of these results with the previous study confirms that a regular participation in external quality assessment (EQA) assures the achievement of a high

The aim of this study was to explore the prevalence and impact of unexplained somatic symptoms during major depression. A total of 560 consecutive outpatients with a major depressive episode according to the DSM-IV (text revision) were evaluated in 30 psychiatric facilities throughout Italy. 'Unexplained' somatic symptoms were evaluated using the 30-item Somatic Symptoms Checklist (SSCL-30). Somatic symptoms were considered explained if they were best accounted for as coming from a concomitant physical illness or side effects. Patients evaluated their own mood symptomatology using the Zung questionnaires for depression and anxiety and the Hypomania Checklist-32. According to the SSCL-30, only 90 subjects (16.1%) had no unexplained somatic symptoms, while 231 (41.3%) had 1-5 unexplained symptoms and 239 (42.7%) had more than 5. Asthenia was the most commonly observed unexplained somatic symptom (53% of patients). Unexplained somatic symptoms were more common in females and among those suffering from major depression and depression not otherwise specified rather than in patients with recurrent major depression and bipolar disorders. No relationship between unexplained somatic symptoms and hypomanic features was observed. The presence of a large number of unexplained somatic symptoms is associated with more severe depression and higher rates of misdiagnosis and inappropriate treatment. Copyright © 2011 S.

Full Text Available Background: Women in the perimenopausal period are reported to be vulnerable to psychiatric disorders. Aim: To assess the psychiatric morbidity in perimenopausal women aged 45–55 years. Materials and Methods: This cross-sectional, observational, hospital-based study was conducted at the Department of Psychiatry in a tertiary care hospital attached to a medical college. The study sample consisted of consecutive women in perimenopause as diagnosed by a gynecologist and written informed consent for inclusion in the study. Women with a previous history of psychiatric illnesses, with a major medical illness, or who had undergone surgical menopause were excluded from the study. All women were evaluated with a brief questionnaire for collecting demographic and clinical information and the Mini International Neuropsychiatric Interview for assessing psychiatric disorders. Results: Of the 108 women in perimenopause included in the study, 31% had depressive disorder, 7% had anxiety, while 5% had depressive disorder with anxiety features. Psychiatric morbidity was significantly more in women having lesser education, from rural background, with a history of psychiatric illness in the family, a later age of menarche, and in the late stage of perimenopause. Conclusions: Women in the perimenopause affected by psychiatric morbidity were most commonly diagnosed with depression. As perimenopause is a time of vulnerability in women, attention to signs and symptoms of depression may be required so that they may lead a more productive life.

MODULAR ANALYTICS (Roche Diagnostics) (MODULAR ANALYTICS, Elecsys and Cobas Integra are trademarks of a member of the Roche Group) represents a new approach to automation for the clinical chemistry laboratory. It consists of a control unit, a core unit with a bidirectional multitrack rack transportation system, and three distinct kinds of analytical modules: an ISE module, a P800 module (44 photometric tests, throughput of up to 800 tests/h), and a D2400 module (16 photometric tests, throughput up to 2400 tests/h). MODULAR ANALYTICS allows customised configurations for various laboratory workloads. The performance and practicability of MODULAR ANALYTICS were evaluated in an international multicentre study at 16 sites. Studies included precision, accuracy, analytical range, carry-over, and workflow assessment. More than 700 000 results were obtained during the course of the study. Median between-day CVs were typically less than 3% for clinical chemistries and less than 6% for homogeneous immunoassays. Median recoveries for nearly all standardised reference materials were within 5% of assigned values. Method comparisons versus current existing routine instrumentation were clinically acceptable in all cases. During the workflow studies, the work from three to four single workstations was transferred to MODULAR ANALYTICS, which offered over 100 possible methods, with reduction in sample splitting, handling errors, and turnaround time. Typical sample processing time on MODULAR ANALYTICS was less than 30 minutes, an improvement from the current laboratory systems. By combining multiple analytic units in flexible ways, MODULAR ANALYTICS met diverse laboratory needs and offered improvement in workflow over current laboratory situations. It increased overall efficiency while maintaining (or improving) quality.

The aim of this study was to prepare, pilot and validate a questionnaire to evaluate patient safety in the specific context of clinical laboratories. A specific questionnaire on patient safety in the laboratory, with 62 items grouped into six areas, was developed, taking into consideration the diverse human and laboratory contextual factors which may contribute to producing errors. A pilot study of 30 interviews was carried out, including validity and reliability analyses using principal components factor analysis and Cronbach's alpha. Subsequently, 240 questionnaires were sent to 21 hospitals, followed by a test-retest of 41 questionnaires with the definitive version. The sample analyzed was composed of 225 questionnaires (an overall response rate of 80%). Of the 62 items initially assessed, 17 were eliminated due to non-compliance with the criteria established before the principal components factor analysis was performed. For the 45 remaining items, 12 components were identified, with an cumulative variance of 69.5%. In seven of the 10 components with two or more items, Cronbach's alpha was higher than 0.7. The questionnaire items assessed in the test-retest were found to be stable. We present the first questionnaire with sufficiently proven validity and reliability for evaluating patient safety in the specific context of clinical laboratories. This questionnaire provides a useful instrument to perform a subsequent macrostudy of hospital clinical laboratories in Spain. The questionnaire can also be used to monitor and promote commitment to patient safety within the search for continuous quality improvement. Copyright © 2011 SESPAS. Published by Elsevier Espana.

This study aimed to analyse and redesign the outpatient clinic in a paediatric department. The study was a joint collaboration with the doctors of the department (paediatric residents and specialists) using the Change Laboratory intervention method as a means to model and implement change in the outpatient clinic. This study was motivated by a perceived failure to integrate the activities of the outpatient clinic, patient care and training of residents. The ultimate goal of the intervention was to create improved care for patients through resident learning and development. We combined the Change Laboratory intervention with an already established innovative process for residents, 3-h meetings. The Change Laboratory intervention method consists of a well-defined theory (Cultural-historical activity theory) and concrete actions where participants construct a new theoretical model of the activity, which in this case was paediatric doctors' workplace learning modelled in order to improve medical social practice. The notion of expansive learning was used during the intervention in conjunction with thematic analysis of data in order to fuel the process of analysis and intervention. The activity system of the outpatient clinic can meaningfully be analysed in terms of the objects of patient care and training residents. The Change Laboratory sessions resulted in a joint action plan for the outpatient clinic structured around three themes: (1) Before: Preparation, expectations, and introduction; (2) During: Structural context and resources; (3) After: Follow-up and feedback. The participants found the Change Laboratory method to be a successful way of sharing reflections on how to optimise the organisation of work and training with patient care in mind. The Change Laboratory approach outlined in this study succeeded to change practices and to help medical doctors redesigning their work. Participating doctors must be motivated to uncover inherent contradictions in their

The AstraZeneca and Covance Laboratories Clinical Bioanalysis Alliance (CBioA) was launched in 2011 after a period of global economic recession. In this challenging environment, AstraZeneca elected to move to a full and centralized outsourcing model that could optimize the number of people supporting bioanalytical work and reduce the analytical cost. This paper describes the key aspects of CBioA, the innovative operational model implemented, and our ways of ensuring this was much more than simply a cost reduction exercise. As we have recently passed the first 5-year cycle, this paper also summarizes some of the concluding benefits, wins and lessons learned, and how we now plan to extend and develop the relationship even further moving into a new clinical laboratory partnership.

Real-time PCR has revolutionized the way clinical microbiology laboratories diagnose many human microbial infections. This testing method combines PCR chemistry with fluorescent probe detection of amplified product in the same reaction vessel. In general, both PCR and amplified product detection are completed in an hour or less, which is considerably faster than conventional PCR detection methods. Real-time PCR assays provide sensitivity and specificity equivalent to that of conventional PCR combined with Southern blot analysis, and since amplification and detection steps are performed in the same closed vessel, the risk of releasing amplified nucleic acids into the environment is negligible. The combination of excellent sensitivity and specificity, low contamination risk, and speed has made real-time PCR technology an appealing alternative to culture- or immunoassay-based testing methods for diagnosing many infectious diseases. This review focuses on the application of real-time PCR in the clinical microbiology laboratory. PMID:16418529

We aimed to determine clinical, laboratory and demographical characteristics of tularemia on admission to Emergency Department (ED). Medical data of 317 patients admitted to ED and subsequently hospitalized with suspected tularemia between January 1, 2011, and May 31, 2015, were collected. Patients were divided into 2 groups according to microagglutination test results, as tularemia (+) and tularemia (-). Of the 317 patients involved, 49 were found to be tularemia (+) and 268 were tularemia (-). Mean age of the tularemia (+) patients was found to be higher than that of tularemia (-) patients. When compared to tularemia (-) patients, a significant portion of patients in tularemia (+) patients were elderly, living in rural areas and had contact with rodents. When clinical and laboratory findings of the 2 groups were compared, any statistical significance could not be determined. Tularemia is a disease of elderly people living in rural areas. Contact with rodents also increases risk of tularemia in suspected patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Brucellosis is the most common zoonotic disease worldwide and remains an important human disease especially in developing countries. The aim of the present study was to evaluate clinical manifestations and laboratory findings of childhood brucellosis in Van province of Eastern Turkey. To our knowledge, this is the largest series of childhood brucellosis reported in the literature. In this retrospective study, 496 children with brucellosis were assessed for the clinical manifestations and laboratory findings from July 2009 through December 2013. The diagnosis of brucellosis was based on clinical findings and a standard tube agglutination test (titer ≥ 1:160). Data were analyzed using Minitab version 16. The study included 496 children (boys, 60.5%) with a mean age of 10.0 ± 3.95 years (range, 1-16 years). The most frequent clinical symptoms were arthralgia (46.2%), fever (32.1%), and abdominal pain (17.1%) and the most common clinical signs were peripheral arthritis (10.1%), splenomegaly (2.2%) and hepatomegaly (1.8%). The most contagious seasons were summer and autumn (63.3%). Elevated lactate dehydrogenase and C-reactive protein and erythrocyte sedimentation rate were reported in 63.1%, 58.7%, and 55.2% of the patients, respectively. Anemia (20.4%), thrombocytopenia (15.5%), and leukopenia (12.1%) were the most common hematologic findings. Brucellosis remains a serious public health problem in Turkey. The clinical and laboratory characteristics of childhood brucellosis have been described in order to assist clinicians in diagnosing and monitoring the disease. © 2015 Japan Pediatric Society.

Background In-hospital hypovitaminosis C is highly prevalent but almost completely unrecognized. Medical awareness of this potentially important disorder is hindered by the inability of most hospital laboratories to determine plasma vitamin C concentrations. The availability of a simple, reliable method for analyzing plasma vitamin C could increase opportunities for routine plasma vitamin C analysis in clinical medicine. Methods Plasma vitamin C can be analyzed by high perf
