Diagnosis and evaluation of small airway disease and COPD using impulse oscillometry.

Impulse oscillometry (IOS) is a sensitive tool for assessing small airway function in patients with chronic obstructive pulmonary disease (COPD). This study aimed to differentiate between COPD, small airway disease (SAD), and normal groups using IOS, and to evaluate the clinical applicability of IOS. This retrospective cohort study was conducted from January 2020 to February 2022. The eligible population comprised adult patients who simultaneously underwent IOS and pulmonary function tests. The diagnostic value of IOS in differentiating SAD and/or COPD from control was analyzed, and the correlations among IOS parameters, lung function, and radiological assessment results were determined. Among the enrolled 306 patients, 38 (12.4%) had SAD and 134 (43.8%) had COPD. The remainder comprised the control group without COPD and/or SAD. Abnormal airway resistance according to IOS parameters was detected in 17.2% of the patients in the control group, 47.2% of those in the SAD group, and 55.2% of those in the COPD group. Airway resistance estimated by IOS were significantly higher in the SAD and COPD groups than in the control group and correlated with lung function and radiological airway wall thickness. We developed a composite index called the IOS severity index (IOSsi) using IOS parameters that can predict SAD and COPD, and IOSsi showed significantly differentiation of SAD and/or COPD from control. Especially, IOSsi value ≥ 4 was associated with an increased risk of SAD and/or COPD and also with risk for moderate-to-severe exacerbation in patients with COPD. IOS may be a useful tool to differentiate disease status and evaluate disease severity and prognosis in patients with SAD and/or COPD, and a prognostic factor of COPD.

Immunosuppressive Drugs in Early Limited Cutaneous Systemic Sclerosis May Prevent Global Damage Accrual.

Organ damage in systemic sclerosis (SSc) in individual organs such as the lungs may be prevented by immunosuppressive drugs (IS). A new measure of global organ damage, the Scleroderma Clinical Trials Consortium Damage Index (SCTC-DI), has allowed us to investigate whether IS may reduce global organ damage accrual in early SSc. This was a retrospective study of patients with < 2 years disease duration in Canadian and Australian SSc cohorts. Patients with either limited cutaneous (lcSSc) or diffuse cutaneous (dcSSc) SSc were observed separately and divided into ever or never exposed to IS groups. The SCTC-DI was the outcome and inverse probability of treatment weighting (IPTW) was used to balance the study groups and to fit a marginal structural generalized estimating equation (GEE) model. In the lcSSc cohort, there were 210 subjects of which 34% were exposed to IS at some time. Exposure to IS was associated with lower damage scores. In the dcSSc cohort, there were 192 subjects of which 76% were exposed to IS at some time. Exposure to IS was not associated with damage scores. In this retrospective observational cohort study, using IPTW to adjust for confounders, we found a protective effect of the use of IS on damage accrual in lcSSc. We were unable to determine such an effect in dcSSc but unknown confounders may have been present and prospective studies of IS in dcSSc should include the SCTC-DI to determine the possible effect of IS on damage accrual.

A prospective observational study on maternal diet pre- and post-GDM diagnosis and pregnancy outcomes in individuals with/without GDM.

To investigate (1) the association between maternal dietary choices during the first and second trimesters and the diagnosis of gestational diabetes mellitus (GDM), (2) the association between a GDM diagnosis and dietary choices during pregnancy, and (3) the differences in pregnancy outcomes between individuals with and without GDM. A prospective cohort study. Pregnant individuals with singleton pregnancy aged 19 ∼ 44 years, without severe pregnancy complications were enrolled in the study. Dietary data were collected at three time points during routine antenatal appointments: 8 ∼ 12 weeks gestation(n = 993), 20 ∼ 24 weeks gestation(n = 732), and 32 ∼ 36 weeks gestation(n = 536). GDM diagnosis and pregnancy outcomes were collected during follow-up from the electronic medical record (EMR). A total of 93 participants (12.9%) were diagnosed with GDM. Livestock and poultry meat intake during the second trimester were associated with an increased risk of developing GDM (aOR 1.371, 95%CI 1.070-1.756, P = 0.013), and a GDM diagnosis may lead to decreased intake of cereals and its products (P = 0.001), potatoes and its products (P < 0.001), and fruit (P = 0.002) and increased intake of fish, shrimp and shellfish (P = 0.001), eggs (P = 0.015), and milk and milk products (P = 0.011) in the third trimester. Individuals with GDM related to lower risk of excessive gestational weight gain (aOR 0.384, 95%CI 0.188-0.646, P = 0.001) but may increase the risk of fetal macrosomia (aOR 3.873, 95%CI 1.364-10.996, P = 0.011). Understanding maternal dietary choices around GDM diagnosis is crucial for accurate nutritional assessment and effective education programs. While our findings suggest dietary changes may occur post-diagnosis, further research is needed to confirm these patterns and the potential benefits of early dietary counseling for individuals with GDM.

The Longitudinal Implementation of a Mental Health Literacy Resource Among Grade 8 and 9 Students in a Catholic School Setting

ABSTRACT Background Mental disorders most likely manifest during adolescence, providing opportunities for schools and professionals to implement standardized mental health literacy (MHL) interventions to support improvement of mental health outcomes. Purpose This study aimed to evaluate the impact of an MHL intervention (the Guide) on knowledge, stigma, help-seeking and overall mental health among grade 8–9 students. Methods We developed a longitudinal cohort study to evaluate the Guide among 523 students, delivered across subsequent grade levels within a Catholic school board in Canada. We utilized validated measures to assess mental health knowledge, stigma, help seeking attitudes, and mental health across four time-points: baseline, end of grade 8, beginning of grade 9, and end of grade 9. Teachers undertook training to learn how to administer the intervention, utilize included teaching aids, and collect data. Results Students demonstrated improvements on knowledge and stigma at all measurement intervals, however statistically significant differences in help-seeking and well-being outcomes were not observed. Discussion This study suggests the plausibility of longer-term delivery of the Guide and similar resources in enhancing knowledge and reducing stigma among similar youth cohorts. Translation to Health Education Practice Certified Health Education Specialists may adapt the Guide to accommodate youth mental health needs in different contexts.

Effects of acetaminophen use on mortality of patients with acute respiratory distress syndrome: secondary data mining based on the MIMIC-IV database.

Acetaminophen is a commonly used analgesic after surgery, and its impact on prognosis in patients with acute respiratory distress syndrome (ARDS) has not been studied. This study explores the association between the use of acetaminophen and the risk of mortality in patients with ARDS. In this retrospective cohort study, 3,227 patients with ARDS who had or had not received acetaminophen were obtained from the Medical Information Mart for Intensive Care IV, patients were divided into acetaminophen and non- acetaminophen groups. In-hospital mortality of ARDS patients was considered as primary end point. We used univariate and multivariate Cox regression analyses to assess the relationship of acetaminophen use and in-hospital mortality in patients with ARDS. Subgroup analysis was performed according to age, gender, and severity of ARDS. Of the total patients, 2,438 individuals were identified as acetaminophen users. The median duration of follow-up was 10.54 (5.57, 18.82) days. The results showed that the acetaminophen use was associated with a decreased risk of in-hospital mortality [hazard ratio (HR) = 0.67, 95% confidence interval (CI): 0.57-0.78]. Across various subgroups of patients with ARDS based on age, gender, and severity, acetaminophen use exhibited an association with reduced risk of in-hospital mortality. Acetaminophen use was associated with in-hospital mortality of patients with ARDS. Acetaminophen therapy may represent a promising therapeutic option for ARDS patients and warrants further investigation.

Multimorbidity and risk of adverse outcomes in the Hertfordshire Cohort Study: does sex matter?

We examined whether admission risk increases at a certain threshold of number of systems medicated or whether any increase confers greater admission risk in either sex in a community-dwelling cohort of older persons in Hertfordshire. This study uses a longitudinal retrospective study design. Data from 2997 men and women (aged 59-73 at baseline) were analyzed. Participants were followed up from baseline (1998-2004) until December 2018 using Hospital Episode Statistics and mortality data, reporting clinical outcomes using ICD-10 coding. Number of systems medicated in relation to mortality (all-cause, cancer-related, cardiovascular-related) and admission (any, neurological, cardiovascular, and respiratory) were examined using Cox regression. Apart from cancer-related mortality among women, more systems medicated predicted increased risk of all events among both sexes (p ≤ 0.001). For 'any', cardiovascular and respiratory admissions, there were increases in risk for each category of number of systems medicated. For example, compared to men with no systems medicated, those with 1, 2 and > 2 systems medicated had hazard ratios (95% CI) for cardiovascular admissions of 1.82 (1.57,2.12), 2.39 (2.00,2.84) and 3.45 (2.84,4.20) respectively; estimates among women were 1.74 (1.44,2.11), 2.35 (1.92,2.88) and 3.40 (2.79,4.13). Increases in numbers of systems medicated conferred greater risk of admission in both sexes. Interventions aimed at reducing the burden of chronic disease in mid-late adulthood are required.

COMPLEXITY OF PITUITARY ADENOMA SURGERY

Introduction Pituitary adenomas are the most common intraselllar tumors, representing 16% of all intracranial lesions. Although the symptomatology is very complex, it requires a multimodal treatment plan, in order to cover all corners of this combined pathology. Mostly the treatment is surgical, hormonal or combined. The transnazosphenoidal corridor offers a optimal visualitation of the anatomic location (via microscope or endoscope) but also comes with a variety of morbidities, one of the most important being the cerebrospinalfluid fistula (CSF leak). Objective We effectuated a retrospective cohort study in which we included patients with pituitary adenoma who were operated in the Clinic of Neurosurgery from Targu-Mures Emergency County Hospital between January 2018 and April 2024 with full documentation, including complications (apoplexy, infections, CSF fistula etc.). Results A total of 45 patients passed the inclusion criteria with a predominance of female patients (60%, n=27) with a mean age of 55.77 years. Analizing the clinical and paraclinical data, there were 39 patients with macroadenoma (vs. microadenoma n=6), with the dominant symptomatology being headache (86.66%) and visual disturbances (66.66%). In 32 cases the transnazosphenoidal (TSS) approach was used (1 case endoscopic and 31 cases microscopic), in 10 cases pure transcranian with modified pterional or subfrontal craniotomy and in 3 cases there was a combined approach. Postoperative complications were encountered in 8 cases (17.77%), and death in 1 case. 6 patients presented postoperative CSF fistula. In 16 cases we encountered postoperative Diabetes Insipidus with a significant difference in the tumor volume favoring this manifestation (p=0.0001). There was no significance found between the volume of the tumor and postoperative CSF leak (p=0.665). In 31 cases (68.88%) the TSS approach was used and the closing of the sphenoid sinus and cranial base was effectuated in a classic manner with fat, fascia and muscle; in additional cases specified glues were used. Conclusions Our study wants to reflect on the importance of anterior/middle cranial base closure, taking into account the possible postoperative complications. It is important to be aware of the technique of different nasoseptal flaps in order to prevent CSF fistula and reduce postoperative complications.

High-dose folic acid use and cancer risk in women who have given birth: A register-based cohort study.

This study was undertaken to study whether high-dose folic acid (>1 mg daily) use is associated with an increased risk of cancer in all women who have given birth and in women with epilepsy. High-dose folic acid supplementation during pregnancy has been linked to increased cancer risk in children born to mothers with epilepsy. We identified women with their first pregnancy in Denmark (1997-2017), Norway (2005-2017), and Sweden (2006-2017) using medical birth registers, linking individual data across nationwide health registers and statistical agencies. Exposure was defined as filled prescriptions for high-dose folic acid, considered time-varyingly. The primary outcome was the first malignant cancer diagnosis. Hazard ratios (HRs) of cancer after high-dose folic acid exposure were estimated using Cox proportional hazard models with 95% confidence intervals (CIs), adjusted for confounders including antiseizure medication (ASM) use, and stratified by maternal epilepsy diagnosis. A 6-month time lag was applied, as cancer is unlikely to develop immediately. With up to 21 years of follow-up, we identified 1 465 785 women who gave birth, including 64 485 (4.4%) exposed to high-dose folic acid. In the exposed group, 755 cancer cases were observed (208 per 100 000 person-years, 95% CI = 193.8-223.5), compared with 18 702 cases in the unexposed group (164 per 100 000 person-years, 95% CI = 161.5-166.2), yielding a 20% increased cancer risk overall (adjusted HR = 1.2, 95% CI = 1.1-1.2). This risk was attenuated after the 6-month lag analysis (adjusted HR = 1.1, 95% CI = 1.04-1.2). The risk for non-Hodgkin lymphoma was increased in all analyses (n = 28, adjusted HR = 2.0, 95% CI = 1.3-2.9). The association between high-dose folic acid use and overall cancer risk was similar in those with epilepsy regardless of ASM use (adjusted HR = 1.3, 95% CI = 1.0-1.8). High-dose folic acid use was associated with increased overall cancer risk in women who have given birth, with a consistent association with non-Hodgkin lymphoma, including those with epilepsy, regardless of ASM use.

Assisted reproductive technology, pregnancy and recurrent disease in melanoma patients: a 30-year single institution experience.

Objectives The aim of this study is to assess differences in melanoma recurrence between patients conceiving spontaneously versus those undergoing assisted reproductive technology (ART), to determine use of ART in post-melanoma patients and to examine the impact of counseling of this specific patient group. Design This study is a 30-year analysis including data from a single center questionnaire and a retrospective cohort study. Participants/Materials Women of childbearing age with a history of melanoma were requested to participate in our study. We selected patients who underwent either primary melanoma treatment or treatment of local / distant recurrence at our institute between 1994 and 2021. Each participant received a questionnaire and informed consent form. The questions concerned general health, primary tumor characteristics, utilization of ART, subsequent pregnancies and development of recurrent melanoma. Additional information was collected from the medical files. Setting The research was conducted in a dedicated oncology center and tertiary referral center for melanoma in The Netherlands. Methods Participants received the questionnaires by mail. Six weeks later a reminder was sent to non-responders. Analysis was performed using descriptive statistics. For comparisons between groups Chi-square tests were used. P-value was considered significant when below 0.05. A clinically relevant difference in recurrence rate was defined as a 10% difference. Results A total of 498 questionnaires were available for analyses, 449 from living patients and 49 from relatives of diseased patients. One hundred and seventy-nine patients (36%) with a history of melanoma became pregnant following their diagnosis. In this group, 28 patients (16%) attempted to conceive using ART, and eight of them experienced disease recurrence. There was no difference in the recurrence rate between patients who became pregnant after the diagnosis of melanoma and those who never subsequently conceived (37% vs 35%, p=0.609). Limitations The main limitations of the study are its size, observational design and questionnaire methodology. Conclusions Pregnancy did not increase the risk of recurrent melanoma. The group of patients conceiving after ART was small and therefore it is difficult to confidently conclude that the recurrence risk is comparable to the other groups. Prospective international registration of these patients, their oncologic follow-up and possible use of assisted reproduction, will provide valuable information to determine any potential association between ART and risk of recurrent melanoma. This would enable health professionals to develop surveillance strategies and pre-conception counselling of patients wishing to conceive.

Warmblood fragile foal syndrome: Pregnancy loss in Warmblood mares.

Fragile foal syndrome (FFS) or warmblood FFS Type 1 (WFFS) is a recessive, autosomal, hereditary, genetic defect causing late abortions, stillbirths and non-viable foals. Whether early pregnancy losses occur is unknown. To investigate how WFFS affects pregnancies and whether early pregnancy losses occur in WFFS matings and if there is a difference in pregnancy success between matings where both parents were allele carriers and those where only mare or stallion were WFFS carriers. Retrospective cohort study. Breeding records from a Warmblood stud farm were evaluated (2016-2019) and 2682 cycles of 177 mares analysed. Matings were assigned to four study groups, depending on the WFFS carrier status of the mare and stallion: N/WFFS × N/WFFS (n = 46), N/WFFS (mares) × N/N (n = 511), N/N × N/WFFS (stallions) (n = 191) and N/N × N/N (n = 2149). There were no differences in pregnancy rates between matings with only one WFFS carrier and those with non-carriers. When comparing N/WFFS × N/WFFS matings to those with only one or no WFFS-carrier, there were no increased pregnancy losses in the embryonic phase (day <42). By contrast, the N/WFFS × N/WFFS group had significantly more abortions (53.8%) than the other three study groups (7.9-9.2%; adjusted p < 0.0001). The higher losses were evenly distributed between the early (D42-150: 22.7% losses, n = 5) and late (D150-300: 29.4% losses, n = 5) foetal phase. The live foal rate per pregnancy for N/WFFS × N/WFFS matings was lowest (34.5%) and differed significantly (other groups 81%-84%; adjusted p < 0.0001); the peri- and postnatal mortality was higher (25%) compared with the other study groups (2.6%-3%). Low sample size in N/WWFS × N/WFFS matings, unbalanced study design, outcomes are descriptive, all mares from one stud farm. The mating of two WFFS carriers may lead to increased risks of pregnancy and foal loss.

Opioid Use Following Spine Surgery in Ambulatory Surgical Centers Versus Hospital Outpatient Departments.

Retrospective cohort study. To assess the association between undergoing spine surgery in an ambulatory surgical center (ASC) vs a hospital outpatient department (HOPD) and (a) perioperative opioid prescription patterns and (b) prolonged opioid use. Data from the Merative MarketScan Database included patients aged 18-64 who underwent single-level or multilevel anterior cervical discectomy and fusion (ACDF) or lumbar decompression between January 2017 and June 2021. Primary outcomes included receipt of a perioperative opioid prescription, perioperative oral morphine milligram equivalents (MMEs), and prolonged opioid use (defined as opioid prescription 91-180days post-surgery). Secondary outcomes included the number of perioperative opioid prescriptions filled (single/multiple) and type of initial perioperative opioid filled (potent/weak). Analysis of prolonged opioid use was limited to opioid-naive patients. Propensity score matching (1 ASC to 3 HOPD cases) and logistic regression models were used for analysis. The study included 11,654 ACDF and 26,486 lumbar decompression patients. For ACDF, ASCs had higher odds of an initial potent opioid prescription (OR = 1.18, 95% CI 1.08-1.30, P < .001) and higher total adjusted mean MMEs (+21.14, 95% CI 3.08-39.20, P = .02). For lumbar decompression, ASCs had increased odds of an initial potent opioid (OR = 1.23, 95% CI 1.16-1.30, P < .001) but lower odds of multiple opioid prescriptions (OR = 0.90, 95% CI 0.85-0.96, P < .001). There was no significant association between the surgery setting and prolonged opioid use. Differences in perioperative opioid prescribing were observed between ASCs and HOPDs, but there was no increase in prolonged opioid use in ASCs. Further research is needed to optimize postoperative pain management in different outpatient settings.

Registration and management of children with overweight by general practitioners in The Netherlands

Background General practitioners (GPs) form the gateway to healthcare in numerous European countries. Their role in addressing and managing overweight/obesity in children is crucial. In Dutch guidelines, GPs are encouraged to proactively address weight-related issues during patient consultations, regardless of the initial reason of the visit. Objective(s) To examine the frequency, management and follow-up of GP visits of children for overweight/obesity and the identification by GPs of these children presenting with other complaints. Methods A retrospective cohort study. Health records from 2012–2021 in the Rijnmond Primary Care Database (RPCD) of children aged 2–18 with overweight/obesity who visited the GP were analysed. Children were categorised into two groups: those visiting for weight-related issues (group 1) and those visiting for other complaints but identified as overweight or obese by GPs (group 2). Data on patient demographics, reasons for contact, and management strategies were extracted. Results From the 120,991 children, 3035 children with documented overweight or obesity were identified, 208 were excluded. The study population comprised 2827 individuals: 55% belonging to group 1, 45% to group 2. The frequency of first visits remained stable at approximately 0.5% visits per total person-years each year. Group 1 received more referrals (74%) and follow-up consultations (45.5%) than group 2 with 17% referrals and 19.7% follow-up consultations. Conclusion This study highlights a concerning difference in the management of the two groups. Strategies for effective management of overweight in children and the GP’s role, warrant further investigation. Especially when overweight is not the primary reason for visit.

A prospective analysis of clinical and parasitological outcomes after treatment or a wait-and-see approach of Dientamoeba fragilis infection in an adult general practice population.

Dientamoeba fragilis is a protozoan frequently encountered in stool samples globally. It is debated whether Dientamoeba fragilis carries pathogenic capacities. This study prospectively analyses clinical and parasitological outcomes after treatment or a wait-and-see approach of Dientamoeba fragilis infection in a general practice adult population. In this prospective observational cohort study 113 adult patients with a positive Polymerase Chain Reaction (PCR) test result for D. fragilis (T0) in a primary care setting, were followed-up longitudinally with a control PCR-test and microscopic stool examination at 30 days (T1) and 90 days (T2) after inclusion. Standardized patient-reported questionnaires including treatment details and the adjusted Irritable Bowel Syndrome-Severity Score (IBS-SS) were retrieved at T0, T1 and T2. Parasitology and questionnaires were retrieved from 87 participants at T0 and T1, and 74 at T2. Treated patients(n = 64) more often tested PCR negative at T1 (64.1% vs. 16.4%, p < 0.001) and T2 (67.3% vs. 5.3%, p < 0.001) compared to untreated patients. No difference in decline in IBS-SS was seen comparing the treatment and non-treatment groups at T1 (p = 0.403) or T2 (p = 1.00). A short and long term increased parasitological clearance is shown with treatment of clioquinol or metronidazole compared with no treatment. A clear and significant correlation between parasitological cure and decline of clinical complaints as reported by the participants could not be established.

Bariatric Surgery Reduced Long-Term Mortality in Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease and Cirrhosis.

With the obesity pandemic, metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common liver disease and a leading cause of end-stage liver disease and liver-related deaths in the U.S.A. Therefore, we aimed to compare the long-term outcomes of patients with MASLD and cirrhosis with and without bariatric surgery. Patients were retrospectively identified from the California Department of Healthcare Access and Information database, 2005 to 2019, for a population-based cohort study. Propensity score matching (PSM) was used to balance background risks between patients with cirrhosis who underwent bariatric surgery and those who did not. Overall, liver-related, and non-liver-related mortality were analyzed. Of 91,708 eligible patients with MASLD and cirrhosis, PSM yielded 2,107 patients who underwent bariatric surgery and 8,428 non-bariatric controls. Compared to matched controls, patients who underwent bariatric surgery had lower 5-year overall (24.9% vs. 37.1%; P < 0.0001), liver-related (3.3% vs. 14%; P < 0.0001), and non-liver-related mortality (22.3% vs. 26.9%; P = 0.046). In multivariable analysis, bariatric surgery was associated with decreased overall mortality (adjusted hazard ratio [aHR] = 0.63; P < 0.0001), liver-related (aHR = 0.24; P < 0.0001), and non-liver-related (aHR = 0.81; P = 0.0026) mortality. However, only laparoscopic surgeries were associated with lower overall mortality (aHR = 0.39; P < 0.0001) whereas open surgeries were associated with higher overall mortality (aHR = 1.24; P = 0.022). Patients with MASLD and cirrhosis who underwent bariatric surgery, specifically laparoscopic approaches, had significantly lower mortality risk than non-surgical counterparts.

Palliative Homecare in Chronic Liver Disease: A Cohort Analysis of Factors and Outcomes Associated with Home Palliative Care in Patients with End-Stage Liver Disease.

Objective: The prevalence and mortality of chronic liver disease has risen significantly. In end-stage liver disease (ESLD), the survival of patients is approximately 2 years. Despite the poor prognosis and high symptom burden, integration of palliative care in ESLD is reduced, and the majority of patients continue to die in inpatient care. We aim to assess predictors and outcomes of home palliative care, as well as factors associated with death at home in patients with ESLD. Methods: Retrospective cohort study of patients with ESLD, followed by a palliative care team between 2017 and 2022. Information regarding patient demographics, ESLD etiology, decompensations, and interventions was collected. Two-sided tests were used to identify factors associated with home palliative care. Results: We analyzed 75 patients: 44% had home palliative care and 33% died at home. ESLD patients with home palliative care were older (72.52 vs 64.45; p = 0.002), had a longer palliative care intervention time (149.97 ± 196.23 vs 43.69 ± 100.60 days; p = 0.007), higher rates of ascites or hepatic encephalopathy (χ2 = 11.024; p = 0.029), and hepatocarcinoma (90.9% vs 64.3%; p = 0.007). Patients with home palliative care had a reduction in-hospital admissions (2.61 vs 1.06; p = 0.000) and a greater probability of death at home (66.7% vs 33.3%; p = 0.000). Patients who died at home (33.3%) were older (72.20 vs 64.40; p = 0.000) and had longer palliative care intervention time (178.80 ± 211.78 vs 46.28 ± 99.67 days; p = 0.006). Conclusion: Home palliative care in ESLD differs based on demographics and disease complications, with a positive impact of homecare translated into a reduction in hospital admissions and an increased probability of death at home.

Postural orthostatic tachycardia syndrome after COVID-19 vaccination: A systematic review.

The global COVID-19 vaccination campaign, with 13.53billion doses administered by early 2024, has significantly reduced severe illness and mortality. However, potential adverse effects, such as Postural Orthostatic Tachycardia Syndrome (POTS), have raised concerns. This systematic review evaluates the incidence, mechanisms, and clinical implications of POTS following COVID-19 vaccination. A systematic search of PubMed, EMBASE, and Web of Science was conducted up to June 7, 2024, following PRISMA guidelines to identify studies related to COVID-19 vaccines and POTS. Eligible studies included randomized controlled trials, cohort studies, cross-sectional studies, case-control studies, case series, and case reports. Screening, data extraction, and quality assessment were independently performed by two reviewers using the Joanna Briggs Institute Checklists and the Newcastle-Ottawa Scale. Of the 1,531 articles identified, 10 met the inclusion criteria, encompassing a total of 284,678 participants. These studies included five case reports, two case series, one cross-sectional study, one prospective observational study, and one cohort study. The cohort study reported that the odds of new POTS diagnoses post-vaccination were 1.33 (95% CI: 1.25-1.41) compared to the 90 days prior. In contrast, the post-infection odds were 2.11 (95% CI: 1.70-2.63), and the risk of POTS was 5.35 times higher (95% CI: 5.05-5.68) post-infection compared to post-vaccination. Diagnostic findings across studies included elevated norepinephrine levels and reduced heart rate variability. Reported management strategies involved ivabradine, intravenous therapies, and lifestyle modifications. The risk of POTS following COVID-19 vaccination is lower than that observed post-SARS-CoV-2 infection; however, existing studies are limited by small sample sizes and methodological variability. Further research is needed to clarify the incidence, mechanisms, and long-term outcomes of vaccine-related POTS to inform effective clinical management strategies.

Repurposing Semaglutide and Liraglutide for Alcohol Use Disorder.

Preliminary studies suggest that glucagon-like peptide-1 receptor (GLP-1) agonists, used to treat type 2 diabetes and obesity, may decrease alcohol consumption. To test whether the risk of hospitalization due to alcohol use disorder (AUD) is decreased during the use of GLP-1 agonists compared with periods of nonuse for the same individual. This cohort study was an observational study conducted nationwide in Sweden using data from January 2006 to December 2023. The population-based cohort was identified from registers of inpatient care, specialized outpatient care, sickness absence, and disability pension. Participants were all residents aged 16 to 64 years who had a diagnosis of AUD. The primary exposure was use of individual GLP-1 agonists (compared with nonuse of GLP-1 agonists), and the secondary exposure was medications with indication for AUD. The primary outcome was AUD hospitalization analyzed in a Cox regression within-individual model. Secondary outcomes were any substance use disorder (SUD)-related hospitalization, somatic hospitalization, and suicide attempt. The cohort included 227 866 individuals with AUD; 144 714 (63.5%) were male and 83 154 (36.5%) were female, with a mean (SD) age of 40.0 (15.7) years. Median (IQR) follow-up time was 8.8 (4.0-13.3) years. A total of 133 210 individuals (58.5%) experienced AUD hospitalization. Semaglutide (4321 users) was associated with the lowest risk (AUD: adjusted hazard ratio [aHR], 0.64; 95% CI, 0.50-0.83; any SUD: aHR, 0.68; 95% CI, 0.54-0.85) and use of liraglutide (2509 users) with the second lowest risk (AUD: aHR, 0.72; 95% CI, 0.57-0.92; any SUD: aHR, 0.78; 95% CI, 0.64-0.97) of both AUD and SUD hospitalization. Use of any AUD medication was associated with a modestly decreased risk (aHR, 0.98; 95% CI, 0.96-1.00). Semaglutide (aHR, 0.78; 95% CI, 0.68-0.90) and liraglutide (aHR, 0.79; 95% CI, 0.69-0.91) use were also associated with decreased risk of somatic hospitalizations but not associated with suicide attempts (semaglutide: aHR, 0.55; 95% CI, 0.23-1.30; liraglutide: aHR, 1.08; 95% CI, 0.55-2.15). Among patients with AUD and comorbid obesity/type 2 diabetes, the use of semaglutide and liraglutide were associated with a substantially decreased risk of hospitalization due to AUD. This risk was lower than that of officially approved AUD medications. Semaglutide and liraglutide may be effective in the treatment of AUD, and clinical trials are urgently needed to confirm these findings.

Complication Rates After Ultrasonography-Guided Nerve Blocks Performed in the Emergency Department.

Ultrasonography-guided nerve blocks (UGNBs) have become a core component of multimodal analgesia for acute pain management in the emergency department (ED). Despite their growing use, national adoption of UGNBs has been slow due to a lack of procedural safety in the ED. To assess the complication rates and patient pain scores of UGNBs performed in the ED. This cohort study included data from the National Ultrasound-Guided Nerve Block Registry, a retrospective multicenter observational registry encompassing procedures performed in 11 EDs in the US from January 1, 2022, to December 31, 2023, of adult patients who underwent a UGNB. UGNB encounters. The primary outcome of this study was complication rates associated with ED-performed UGNBs recorded in the National Ultrasound-Guided Nerve Block Registry from January 1, 2022, to December 31, 2023. The secondary outcome was patient pain scores of ED-based UGNBs. Data for all adult patients who underwent an ED-based UGNB at each site were recorded. The volume of UGNB at each site, as well as procedural outcomes (including complications), were recorded. Data were analyzed using descriptive statistics of all variables. In total, 2735 UGNB encounters among adult patients (median age, 62 years [IQR, 41-77 years]; 51.6% male) across 11 EDs nationwide were analyzed. Fascia iliaca blocks were the most commonly performed UGNBs (975 of 2742 blocks [35.6%]). Complications occurred at a rate of 0.4% (10 of 2735 blocks). One episode of local anesthetic systemic toxicity requiring an intralipid was reported. Overall, 1320 of 1864 patients (70.8%) experienced 51% to 100% pain relief following UGNBs. Operator training level varied, although 1953 of 2733 procedures (71.5%) were performed by resident physicians. The findings of this cohort study of 2735 UGNB encounters support the safety of UGNBs in ED settings and suggest an association with improvement in patient pain scores. Broader implementation of UGNBs in ED settings may have important implications as key elements of multimodal analgesia strategies to reduce opioid use and improve patient care.
