Guide to Utilization of the Microbiology Laboratory for Diagnosis of Infectious Diseases: 2024 Update by the Infectious Diseases Society of America (IDSA) and the American Society for Microbiology (ASM).

The critical nature of the microbiology laboratory in infectious disease diagnosis calls for a close, positive working relationship between the physician and the microbiologists who provide enormous value to the health care team. This document, developed by experts in both adult and pediatric laboratory and clinical medicine, provides information on which tests are valuable and in which contexts, and on tests that add little or no value for diagnostic decisions. Sections are divided into anatomic systems, including Bloodstream Infections and Infections of the Cardiovascular System, Central Nervous System Infections, Ocular Infections, Soft Tissue Infections of the Head and Neck, Upper Respiratory Infections, Lower Respiratory Tract infections, Infections of the Gastrointestinal Tract, Intraabdominal Infections, Bone and Joint Infections, Urinary Tract Infections, Genital Infections, and Skin and Soft Tissue Infections; or into etiologic agent groups, including arboviral Infections, Viral Syndromes, and Blood and Tissue Parasite Infections. Each section contains introductory concepts, a summary of key points, and detailed tables that list suspected agents; the most reliable tests to order; the samples (and volumes) to collect in order of preference; specimen transport devices, procedures, times, and temperatures; and detailed notes on specific issues regarding the test methods, such as when tests are likely to require a specialized laboratory or have prolonged turnaround times. In addition, the pediatric needs of specimen management are also addressed. There is redundancy among the tables and sections, as many agents and assay choices overlap. The document is intended to serve as a reference to guide physicians in choosing tests that will aid them to diagnose infectious diseases in their patients.

Decision aids for people facing health treatment or screening decisions.

BACKGROUND: Patient decision aids are interventions designed to support people making health decisions. At a minimum, patient decision aids make the decision explicit, provide evidence-based information about the options and associated benefits/harms, and help clarify personal values for features of options. This is an update of a Cochrane review that was first published in 2003 and last updated in 2017. OBJECTIVES: To assess the effects of patient decision aids in adults considering treatment or screening decisions using an integrated knowledge translation approach. SEARCH METHODS: We conducted the updated search for the period of 2015 (last search date) to March 2022 in CENTRAL, MEDLINE, Embase, PsycINFO, EBSCO, and grey literature. The cumulative search covers database origins to March 2022. SELECTION CRITERIA: We included published randomized controlled trials comparing patient decision aids to usual care. Usual care was defined as general information, risk assessment, clinical practice guideline summaries for health consumers, placebo intervention (e.g. information on another topic), or no intervention. DATA COLLECTION AND ANALYSIS: Two authors independently screened citations for inclusion, extracted intervention and outcome data, and assessed risk of bias using the Cochrane risk of bias tool. Primary outcomes, based on the International Patient Decision Aid Standards (IPDAS), were attributes related to the choice made (informed values-based choice congruence) and the decision-making process, such as knowledge, accurate risk perceptions, feeling informed, clear values, participation in decision-making, and adverse events. Secondary outcomes were choice, confidence in decision-making, adherence to the chosen option, preference-linked health outcomes, and impact on the healthcare system (e.g. consultation length). We pooled results using mean differences (MDs) and risk ratios (RRs) with 95% confidence intervals (CIs), applying a random-effects model. We conducted a subgroup analysis of 105 studies that were included in the previous review version compared to those published since that update (n = 104 studies). We used Grading of Recommendations Assessment, Development, and Evaluation (GRADE) to assess the certainty of the evidence. MAIN RESULTS: This update added 104 new studies for a total of 209 studies involving 107,698 participants. The patient decision aids focused on 71 different decisions. The most common decisions were about cardiovascular treatments (n = 22 studies), cancer screening (n = 17 studies colorectal, 15 prostate, 12 breast), cancer treatments (e.g. 15 breast, 11 prostate), mental health treatments (n = 10 studies), and joint replacement surgery (n = 9 studies). When assessing risk of bias in the included studies, we rated two items as mostly unclear (selective reporting: 100 studies; blinding of participants/personnel: 161 studies), due to inadequate reporting. Of the 209 included studies, 34 had at least one item rated as high risk of bias. There was moderate-certainty evidence that patient decision aids probably increase the congruence between informed values and care choices compared to usual care (RR 1.75, 95% CI 1.44 to 2.13; 21 studies, 9377 participants). Regarding attributes related to the decision-making process and compared to usual care, there was high-certainty evidence that patient decision aids result in improved participants' knowledge (MD 11.90/100, 95% CI 10.60 to 13.19; 107 studies, 25,492 participants), accuracy of risk perceptions (RR 1.94, 95% CI 1.61 to 2.34; 25 studies, 7796 participants), and decreased decisional conflict related to feeling uninformed (MD -10.02, 95% CI -12.31 to -7.74; 58 studies, 12,104 participants), indecision about personal values (MD -7.86, 95% CI -9.69 to -6.02; 55 studies, 11,880 participants), and proportion of people who were passive in decision-making (clinician-controlled) (RR 0.72, 95% CI 0.59 to 0.88; 21 studies, 4348 participants). For adverse outcomes, there was high-certainty evidence that there was no difference in decision regret between the patient decision aid and usual care groups (MD -1.23, 95% CI -3.05 to 0.59; 22 studies, 3707 participants). Of note, there was no difference in the length of consultation when patient decision aids were used in preparation for the consultation (MD -2.97 minutes, 95% CI -7.84 to 1.90; 5 studies, 420 participants). When patient decision aids were used during the consultation with the clinician, the length of consultation was 1.5 minutes longer (MD 1.50 minutes, 95% CI 0.79 to 2.20; 8 studies, 2702 participants). We found the same direction of effect when we compared results for patient decision aid studies reported in the previous update compared to studies conducted since 2015. AUTHORS' CONCLUSIONS: Compared to usual care, across a wide variety of decisions, patient decision aids probably helped more adults reach informed values-congruent choices. They led to large increases in knowledge, accurate risk perceptions, and an active role in decision-making. Our updated review also found that patient decision aids increased patients' feeling informed and clear about their personal values. There was no difference in decision regret between people using decision aids versus those receiving usual care. Further studies are needed to assess the impact of patient decision aids on adherence and downstream effects on cost and resource use.

Question banks: credit? Or debit? A qualitative exploration of their use among medical students.

BACKGROUND: Online question banks are the most widely used education resource amongst medical students. Despite this there is an absence of literature outlining how and why they are used by students. Drawing on Deci and Ryan's self-determination theory, our study aimed to explore why and how early-stage medical students use question banks in their learning and revision strategies. METHODS: The study was conducted at Newcastle University Medical School (United Kingdom and Malaysia). Purposive, convenience and snowball sampling of year two students were employed. Ten interviews were conducted. Thematic analysis was undertaken iteratively, enabling exploration of nascent themes. Data collection ceased when no new perspectives were identified. RESULTS: Students' motivation to use question banks was predominantly driven by extrinsic motivators, with high-stakes exams and fear of failure being central. Their convenience and perceived efficiency promoted autonomy and thus motivation. Rapid feedback cycles and design features consistent with gamification were deterrents to intrinsic motivation. Potentially detrimental patterns of question bank use were evident: cueing, avoidance and memorising. Scepticism regarding veracity of question bank content was absent. CONCLUSIONS: We call on educators to provide students with guidance about potential pitfalls associated with question banks and to reflect on potential inequity of access to these resources.

Inclusion of person-centred care in UK postgraduate medical education curricula: Interviews and documentary analysis.

BACKGROUND: Person-centred care (PCC) involves placing people at the centre of their healthcare decision making to ensure it meets their needs, values, and personal circumstances. Increasingly, PCC is promoted in healthcare policy and guidance, but little is known about how this is embedded in postgraduate medical training. The aim of this research was to understand how PCC is embedded in UK postgraduate medical training and explore factors influencing inclusion of PCC in curricula content. METHODS: To explore this, we interviewed senior professionals with key roles in the curricula from four UK Royal Colleges (Psychiatrists; Physicians; Surgeons; and GPs) and used framework analysis on interviews and relevant curricula documents to identify themes. RESULTS: Legislation and professional/educational guidance influenced inclusion. PCC definitions and terminology differed and placement within curricula was variable. Royal Colleges defined the curriculum and provided training to ensure competence, but local deaneries independently implemented the curriculum. Trainer engagement was greater than trainee buy in. Quality assurance focused on feedback from trainers and trainees rather than patients, and patient and public involvement in curriculum development, teaching, and assessment was limited. CONCLUSIONS: There is a need for cross-organisation collaboration to develop a PCC competence framework that defines the skills and level of competence required at different points in training, with clarity around the differences between undergraduate and postgraduate requirements. Greater auditing and quality assurance of programme delivery would help identify successful practices to share within and across Royal Colleges, while still maintaining the flexibility of local provision. Engagement with patients and the public in this work can only strengthen provision.

Hyaluronic Acid Fillers to Correct Cleft Lip Asymmetry in Adults: Description of Technique and Patient Reported Outcome Measure Using CLEFT-Q.

OBJECTIVE: To determine the efficacy of hyaluronic acid (HLA) lip filler to correct subtle cleft lip asymmetries in adults using a validated patient reported outcome measure (PROM). DESIGN: Prospective cross sectional. SETTING: UK National Health Service. PATIENTS, PARTICIPANTS: Over 18 years old with repaired cleft lip and dissatisfaction of their lip appearance. INTERVENTIONS: HLA lip filler injection. MAIN OUTCOME MEASURES: A validated, cleft specific PROM, the lip module of CLEFT-Q™ prior to treatment and again after six weeks. RESULTS: 24 patients included. A mean total CLEFT-Q™ score pre-procedure was 14.9 (Stand deviation (SD) = 4.91) and 24 (SD = 6.08) post-procedure. Difference in mean total score pre- and post-procedure were statically significant (P = .0001) in all domains on the CLEFT-Q™. No adverse outcomes. CONCLUSION: HLA filler to correct subtle cleft lip asymmetries in adults is a simple low risk technique, which can significantly improve the patient's perception of lip appearance. CONCLUSION: HLA lip filler to correct subtle cleft lip asymmetries in adults is a simple technique, low risk procedure which can significantly improve the patient's perception of lip appearance.

Development and user-testing of a digital patient decision aid to facilitate shared decision-making for people with stable angina.

BACKGROUND: Research shows that people with stable angina need decision support when considering elective treatments. Initial treatment is with medicines but patients may gain further benefit with invasive percutaneous coronary intervention (PCI). Choosing between these treatments can be challenging for patients because both confer similar benefits but have different risks. Patient decision aids (PtDAs) are evidence-based interventions that support shared decision-making (SDM) when making healthcare decisions. This study aimed to develop and user-test a digital patient decision aid (CONNECT) to facilitate SDM for people with stable angina considering invasive treatment with elective PCI. METHODS: A multi-phase study was conducted to develop and test CONNECT (COroNary aNgioplasty dECision Tool) using approaches recommended by the International Patient Decision Aid Standards Collaboration: (i) Steering Group assembled, (ii) review of clinical guidance, (iii) co-design workshops with patients and cardiology health professionals, (iv) first prototype developed and 'alpha' tested (semi-structured cognitive interviews and 12-item acceptability questionnaire) with patients, cardiologists and cardiac nurses, recruited from two hospitals in Northern England, and (v) final PtDA refined following iterative user-feedback. Quantitative data were analysed descriptively and qualitative data from the interviews analysed using deductive content analysis. RESULTS: CONNECT was developed and user-tested with 34 patients and 29 cardiology health professionals. Findings showed that CONNECT was generally acceptable, usable, comprehensible, and desirable. Participants suggested that CONNECT had the potential to improve care quality by personalising consultations and facilitating SDM and informed consent. Patient safety may be improved as CONNECT includes questions about symptom burden which can identify asymptomatic patients unlikely to benefit from PCI, as well as those who may need to be fast tracked because of worsening symptoms. CONCLUSIONS: CONNECT is the first digital PtDA for people with stable angina considering elective PCI, developed in the UK using recommended processes and fulfilling international quality criteria. CONNECT shows promise as an approach to facilitate SDM and should be evaluated in a clinical trial. Further work is required to standardise the provision of probabilistic risk information for people considering elective PCI and to understand how CONNECT can be accessible to underserved communities.

Twelve tips for small group teaching 2.0 - Rebooted for remote and HyFlex learning.

Small group teaching (SGT) is not just the delivery of teaching to a small number of learners - it is, instead, underpinned by learner-learner interaction, discussion, and collaboration. The advent of readily available technology, combined with the need to maintain learner and teacher safety during the COVID-19 pandemic, has led to a surge in remote learning, and significant increases in synchronous hybrid learning environments, also known as HyFlex learning, in which some learners join remotely and others do so in-person. Teaching in this manner brings new challenges and opportunities and, when compared to face-to-face SGT, requires teachers to employ a complementary repertoire of skills. Against this backdrop, and with the pressing need to up-skill teachers in this domain, we take a fresh look at previously published tips for SGT and reboot these strategies in the context of remote and HyFlex SGT. The challenges of adapting these tips in a changed environment will be considered, and refashioned strategies for their application will be offered.

Development and piloting of four decision aids for implantable cardioverter-defibrillators in different media formats.

BACKGROUND: Using DAs for preference-sensitive decisions is an evidence-based way to improve patient-centered decisions. Reimbursement mandates have increased the need for DAs in ICD care, although none have been formally evaluated. The objectives were to develop and pilot implantable cardioverter-defibrillator (ICD) decision aids (DAs) for patients considering primary prevention ICDs. METHODS: Development Phase: An expert panel, including patients and physicians, iteratively developed four DAs: a one-page Option GridTM conversation aid, a four-page in-depth paper tool, a 17-minute video, and an interactive website. Trial Phase: At three sites, patients with heart failure who were eligible for primary prevention ICDs were randomly assigned 2:1 to intervention (received DAs) or control (usual care). We conducted a mixed-methods evaluation exploring acceptability and feasibility. RESULTS: Twenty-one eligible patients enrolled (15 intervention). Most intervention participants found the DAs to be unbiased (67%), helpful (89%), and would recommend them to others (100%). The pilot was feasible at all sites; however, using clinic staff to identify eligible patients was more efficient than chart review. Although the main goals were to measure acceptability and feasibility, intervention participants trended towards increased concordance between longevity values and ICD decisions (71% concordant vs. 29%, p = .06). Participants preferred the in-depth paper tool and video DAs. Access to a nurse during the decision-making window encouraged questions and improved participant-perceived confidence. CONCLUSIONS: Participants felt the DAs provided helpful, balanced information that they would recommend to other patients. Further exploration of this larger context of DA use and strategies to promote independent use related to electrophysiology (EP) visits are needed.

Enhancing shared and surrogate decision making for people living with dementia: A systematic review of the effectiveness of interventions.

BACKGROUND: Dementia can have a profound impact on decision making. People living with dementia (PLwD) often need to make decisions about health care, and, as dementia progresses, decisions may need to be made on their behalf. Specific interventions may support this process. REVIEW QUESTION: What interventions are effective in improving shared decision making or surrogate decision making on the health care of PLwD? METHODS: A narrative systematic review of existing literature was conducted. Seven databases, grey literature and key journals were searched. After exclusion by title, abstracts then full texts were reviewed collaboratively to manage any disagreements. RESULTS: Eight studies met the inclusion criteria. Two articles, including one RCT, evaluated decision aids regarding the use of enteral feeding in advanced dementia. Six further articles, including five RCTs, were found which evaluated the effectiveness of interventions supporting patients or carers with advance care planning. CONCLUSION: Decision-making interventions typically consist of multiple components which aim to establish preferences for future health care. Advance care planning interventions supported aspects of the decision-making processes but their impact on decision quality was rarely evaluated. Interventions did not increase the concordance of decisions with a person's values. The decision-specific interventions are unlikely to produce benefit in other decision contexts. PATIENT INVOLVEMENT: Two caregivers, a public stakeholder group and a carer group were consulted in the design of the wider study to which this review relates. Six PLwD refined the research questions addressed in this paper.

Prevalence and characteristics of women with borderline personality pathology referred to a perinatal consultation liaison service.

OBJECTIVE: To examine the prevalence and characteristics of pregnant women with borderline personality pathology (defined as borderline personality disorder and borderline personality traits) referred to a perinatal consultation-liaison psychiatry service. METHOD: Socio-demographic and clinical data, and diagnoses made according to Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria were recorded for all women referred to and seen by the perinatal consultation-liaison psychiatry service over an 18-month period. Data were analysed using descriptive statistics and logistic regression analysis. RESULTS: A total of 318 women were seen. The most common diagnoses found were depressive disorder (25.5%) and anxiety disorder (15.1%). Borderline personality disorder was found in 10.1% of women and almost one in five women had two or more borderline personality traits (19.5%). When compared to women with other diagnoses, women with borderline personality pathology had higher rates of unplanned pregnancy, being unpartnered, substance use during pregnancy and higher rates of child safety services involvement as a child or in a previous pregnancy. Over 40% of women with borderline personality pathology were referred to child safety services in the current pregnancy and a diagnosis of borderline personality pathology increased the risk of child safety services involvement by almost sixfold (odds ratio: 5.5; 95% confidence interval = [1.50, 20.17]). CONCLUSION: The prevalence of borderline personality pathology in antenatal women identified at antenatal screening and the recognition that women with borderline personality pathology are 'high-risk' caregivers argue for borderline personality pathology to be recognised as a high priority for investment in service development.

Opportunities to enhance ward audit: a multi-site qualitative study.

BACKGROUND: Hospitals in many countries are encouraged to develop audits to assess and improve the quality of care. Ward audit is a specific form of audit and feedback that is commonly used but little studied. The aim of this study is to describe the content and application of hospital ward audit in order to identify potential enhancements to such audits. METHODS: Multiple qualitative methods were used to study a diversity sample of four English National Health Service organisations over a 16-month period. We undertook semi-structured interviews (n = 32), documentary analysis (n = 44) and 25 h of observations of healthcare workers involved in the design and implementation of ward audit. Data were analysed using framework analysis. Findings were presented iteratively to stakeholders who used them to develop a description of the content and delivery of ward audit. RESULTS: Ward audit consisted of seven stages: impetus; method; preparation of staff; assessing practice; analysis; feedback; and decide on action to improve. Two key stages were the monthly assessment of practice using case note data extraction, and the resulting feedback to clinical staff, ward managers, matrons and directors of nursing. At three organisations, the case note data were extracted by staff and there was evidence that this resulted in misrepresentation of the clinical performance audited. The misrepresentation appeared to be associated with the anticipation of punitive feedback from directors of nursing and matrons, as well as time pressures and a lack clarity about the method of audit data collection. Punitive feedback was reported to occur if no data were collected, if data demonstrated poor performance or if performance did not improve. CONCLUSIONS: Organisations invest considerable clinical resources in ward audit, but such audits may have unintended, potentially negative, consequences due to the impacts from punitive feedback. We discuss potential enhancements to ward audit (e.g. providing feedback recipients with suggested actions for improvement) and discuss implications for theory. There is a need to reduce the use of punitive feedback.

The mental health of Australian medical practitioners during Covid-19.

OBJECTIVES: To ascertain whether doctors were experiencing higher rates of distress during Covid-19 and whether this was impacted by demographic factors. Our hypotheses were that being a junior doctor, having a previous mental health diagnosis and treating Covid-19 positive patients would predict higher rates of distress. METHODS: Cross-sectional survey conducted via Survey Monkey. Voluntary participants were recruited from the mailing list of a national-based referral service for doctors to psychiatrists. Distress was measured using the Kessler Psychological Distress Scale (K10). Demographic factors were analysed for predictive value of a higher rating on the K10. Areas of concern in relation to Covid-19 and preference for support services were measured on a Likert scale and compared to levels of distress. RESULTS: The rate of very high distress was 15%. Being a junior doctor and having a previous mental health diagnosis were predictive factors of a higher K10 score. K10 was not affected by likelihood of contact with Covid-19-positive patients. Social isolation had a larger impact on mental health in the context of a previous psychiatric diagnosis. Face-to-face assessments were preferred. CONCLUSIONS: Rates of distress in doctors have been higher than baseline during Covid-19. Some groups have been particularly vulnerable.

Patient experiences of the urgent cancer referral pathway-Can the NHS do better? Semi-structured interviews with patients with upper gastrointestinal cancer.

BACKGROUND: Timeliness is viewed as a key feature of health-care quality. Internationally, this is challenging. In England, cancer waiting time targets are currently not being met. For example, between 2015 and 2018 only 71% of patients with upper gastrointestinal (UGI) cancer started treatment within the recommended 62 days of referral. OBJECTIVE: We explored patients' experiences to identify areas for service improvement. DESIGN: Semi-structured interviews were conducted. SETTING AND PARTICIPANTS: Twenty patients who were referred through the urgent (two-week) GP referral route and were within six months of receiving first treatment were recruited. DATA ANALYSIS: Data from the interviews were analysed thematically. RESULTS: Four themes were developed: organization of care; diagnosis; support; and views and expectations of the NHS. Patients described cross-cutting issues such as complex and varied pathways and uncertainty about what would happen next. They felt daunted by the intensity and speed of investigations. They were presented with a recommended course of action rather than options and had little involvement in decision making. They were grateful for care, reluctant to complain and resigned to the status quo. DISCUSSION AND CONCLUSIONS: In order to meet patient needs, the NHS needs to improve communication and streamline pathways. Future cancer pathways also need to be designed to support shared decision making, be truly person-centred and informed by patient experience.

The Recognition-Response Gap in Acute Stroke: Examining the Relationship between Stroke Recognition and Response in a General Population Survey.

BACKGROUND: Benefits of reperfusion therapies in acute ischemic stroke are highly time-dependent. It is crucial that people who witness the onset of symptoms call emergency medical services (EMS) immediately. The aim of this study was to examine whether there is a gap between recognition of stroke and responding correctly by calling EMS using a scenario-based measure. METHODS: Population-based survey of 1406 individuals from Newcastle upon Tyne, UK, examining stroke recognition and response knowledge using 12 scenario-based vignettes. The response rate was 32% out of 5000 contacted individuals. In total, 16,574 responses to scenarios were examined to investigate whether respondents would recognise stroke symptoms and indicate to call EMS immediately. RESULTS: In 16% of cases people recognised stroke but did not correctly respond by indicating to call EMS. In 49% of responses people recognised stroke and would respond correctly, while in 31% of cases people both failed to correctly recognise and failed to identify the correct response to the stroke scenario. In 5% of cases stroke was not identified but a correct response was indicated. When stroke was recognised, in 25% of responses people indicated that they would not call EMS. Recognition self-efficacy and response self-efficacy were associated with correct response. CONCLUSIONS: A recognition-response gap was identified among UK adults in hypothetical scenarios concerning stroke. Both recognition and translation to adequate EMS response should be explicitly addressed in interventions aiming to improve witness response to stroke. Self-efficacy may be a promising target to close the recognition-response gap.

Clinical Impact of Rapid Point-of-Care PCR Influenza Testing in an Urgent Care Setting: a Single-Center Study.

Seasonal influenza virus causes significant morbidity and mortality each year. Point-of-care (POC) testing using rapid influenza diagnostic tests (RIDTs), immunoassays that detect viral antigens, are often used for diagnosis by physician offices and urgent care centers. These tests are rapid but lack sensitivity, which is estimated to be 50 to 70%. Testing by PCR is highly sensitive and specific, but historically these assays have been performed in centralized clinical laboratories necessitating specimen transport and increasing the time to result. Recently, Clinical Laboratory Improvement Amendments (CLIA)-waived, POC PCR influenza assays have been developed with >95% sensitivity and specificity compared to centralized PCR assays. To determine the clinical impact of a POC PCR test for influenza, we compared antimicrobial prescribing patterns of one urgent care location using the Cobas LIAT Influenza A/B assay (LIAT assay; Roche Diagnostics, Indianapolis, IN) to other urgent care centers in our health system using traditional RIDT, with negative specimens being reflexed to PCR. Antiviral prescribing was lower in patients with a negative LIAT PCR result (2.3%) than in patients with a negative RIDT result (25.3%; P < 0.005). Antivirals were prescribed more often in patients that tested positive by LIAT PCR (82.4%) than in those testing positive by either RIDT or reflex PCR (69.9%; P < 0.05). Antibacterial prescriptions for patients testing negative by LIAT PCR were higher (44.5%) than for those testing negative by RIDT (37.7%), although the difference was not statistically significant. In conclusion, having results from a PCR POC test during the clinic visit improved antiviral prescribing practices compared to having rapid results from an RIDT.

"About sixty per cent I want to do it": Health researchers' attitudes to, and experiences of, patient and public involvement (PPI)-A qualitative interview study.

BACKGROUND: Funders, policy-makers and research organizations increasingly expect health researchers in the UK to involve patients and members of the public in research. It has been stated that it makes research "more effective, more credible and often more cost efficient." However, the evidence base for this assertion is evolving and can be limited. There has been little research into how health researchers feel about involving people, how they go about it, how they manage formal policy rhetoric, and what happens in practice. OBJECTIVE: To explore researchers' experiences and perceptions of patient and public involvement (PPI). METHODS: Semi-structured interview study of 36 health researchers (both clinical and non-clinical), with data collection and thematic analysis informed by the theoretical domains framework. RESULTS: In the course of our analysis, we developed four themes that encapsulate the participants' experiences and perceptions of PPI. Participants expressed ambivalence, cynicism and enthusiasm about PPI, an activity that creates emotional labour, which is both rewarding and burdensome and requires practical and social support. It is operationalized in an academic context influenced by power and incentives. DISCUSSION AND CONCLUSIONS: Researchers' experiences and attitudes towards patient and public involvement are a key factor in the successful embedding of involvement within the wider research culture. We call for a culture change that supports the development of effective organizational approach to support involvement.

Screening for depression with the Edinburgh Postnatal Depression Scale and finding borderline personality disorder.

OBJECTIVE: The aim of the study was to explore the range of psychiatric diagnoses seen in pregnant women who score above the 'cut-off' on the Edinburgh Postnatal Depression Scale when this is used as a routine screening instrument in the antenatal period. METHOD: Subjects were all pregnant women referred to and seen by the Perinatal Consultation-Liaison Psychiatry Team of a tertiary public hospital over a 14-month period. Edinburgh Postnatal Depression Scale score at maternity 'booking-in' visit, demographic and clinical data were recorded and diagnoses were made according to Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria following clinical interview(s) and review of documented past history. Data were analysed using descriptive statistics. RESULTS: A total of 200 patients who had completed the Edinburgh Postnatal Depression Scale were seen for assessment; 86 (43%) scored ⩾13 on Edinburgh Postnatal Depression Scale. Of those scoring 13 or more on Edinburgh Postnatal Depression Scale, 22 (25.6%) had a depressive disorder. In total, 12 patients (14%) had an anxiety disorder, 14 (16.3%) had borderline personality disorder and 13 (15.1%) had a substance use disorder. An additional 23 women (26.7%) had two or more borderline personality traits. CONCLUSION: Psychiatric assessment of women who scored 13 or more on the Edinburgh Postnatal Depression Scale at routine antenatal screening identified a significant number with borderline personality disorder or borderline personality traits rather than depressive or anxiety disorders. Clinical Practice Guidelines note the importance of further assessment for all women who score 13 or more on the Edinburgh Postnatal Depression Scale. The findings here suggest that this assessment should be made by a clinician able to identify personality pathology and organise appropriate and timely interventions.

A Guide to Utilization of the Microbiology Laboratory for Diagnosis of Infectious Diseases: 2018 Update by the Infectious Diseases Society of America and the American Society for Microbiology.

The critical nature of the microbiology laboratory in infectious disease diagnosis calls for a close, positive working relationship between the physician/advanced practice provider and the microbiologists who provide enormous value to the healthcare team. This document, developed by experts in laboratory and adult and pediatric clinical medicine, provides information on which tests are valuable and in which contexts, and on tests that add little or no value for diagnostic decisions. This document presents a system-based approach rather than specimen-based approach, and includes bloodstream and cardiovascular system infections, central nervous system infections, ocular infections, soft tissue infections of the head and neck, upper and lower respiratory infections, infections of the gastrointestinal tract, intra-abdominal infections, bone and joint infections, urinary tract infections, genital infections, and other skin and soft tissue infections; or into etiologic agent groups, including arthropod-borne infections, viral syndromes, and blood and tissue parasite infections. Each section contains introductory concepts, a summary of key points, and detailed tables that list suspected agents; the most reliable tests to order; the samples (and volumes) to collect in order of preference; specimen transport devices, procedures, times, and temperatures; and detailed notes on specific issues regarding the test methods, such as when tests are likely to require a specialized laboratory or have prolonged turnaround times. In addition, the pediatric needs of specimen management are also emphasized. There is intentional redundancy among the tables and sections, as many agents and assay choices overlap. The document is intended to serve as a guidance for physicians in choosing tests that will aid them to quickly and accurately diagnose infectious diseases in their patients.

The influence of endogenous estrogen on transcranial direct current stimulation: A preliminary study.

Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulatory technique. Responses to tDCS differ substantially between individuals. Sex hormones that modulate cortical excitability, such as estrogen, may contribute to this inter-individual variability. The influence of estrogen on tDCS after-effects has not yet been researched. This study aimed to investigate whether endogenous estrogen levels influence cortical response to tDCS. Data from 15 male and 14 female healthy adults were analyzed. Males completed one experimental session. Females completed two, one during the early follicular phase of the menstrual cycle when estrogen was low, one during the mid-luteal phase when estrogen was high. Each session comprised 15-min of anodal tDCS delivered to the left dorsolateral prefrontal cortex (DLPFC). Response to stimulation was assessed using electroencephalography with DLPFC transcranial magnetic stimulation (TMS) administered before, immediately after, and 20-min after tDCS. Changes in amplitudes of N120 and P200 components of TMS-evoked potentials over time were compared between males, women with low estrogen and women with high estrogen. Blood assays verified estrogen levels. Women with high estrogen demonstrated a significant increase in P200 amplitude at both time points and change over time was greater for the high estrogen group compared with males. No significant differences were observed between males and women with low estrogen, or between women with low and high estrogen. These preliminary results indicate that greater neuroplastic response to DLPFC tDCS is seen in highest compared with lowest estrogen states, suggesting that endogenous estrogen levels contribute to inter-individual variability of tDCS outcomes.
