Purpose: Our purpose was to evaluate the characteristics of highly and poorly rated teachers as well as to assess the validity and reliability of those evaluations.
Methods: We downloaded 14 years of medicine faculty evaluations completed by 3rd and 4 year medical students. We dichotomized overall teaching effectiveness as outstanding (receiving "outstanding") or inferior (rated as a "unsatisfactory," "marginal," or "acceptable").
Study Question: To what extent is male physical activity (PA) associated with fecundability (per-cycle probability of conception)?
Summary Answer: Preconception levels of vigorous, moderate, or total PA were not consistently associated with fecundability across Danish and North American cohorts, but there was suggestive evidence that bicycling with a 'soft, comfort seat' was associated with reduced fecundability in both cohorts, especially among males with greater BMI.
What Is Known Already: Among males, some studies indicate that moderate PA might improve fertility, whereas vigorous PA, especially bicycling, might be detrimental.
Study Design, Size, Duration: We assessed the association between male PA and fecundability among couples participating in two preconception cohort studies: SnartForaeldre.
Background: Ventilator-associated pneumonia (VAP) is a challenging nosocomial problem in low- and middle-income countries (LMICs) that face barriers to healthcare delivery and resource availability. This study aimed to examine the incidence and predictors of VAP in Egypt as an example of an LMIC while considering death as a competing event.
Methods: The study included patients aged ≥ 18 years who underwent mechanical ventilation (MV) in an intensive care unit (ICU) at a tertiary care, university hospital in Egypt between May 2020 and January 2023.
Article Synopsis
- A study investigated the effects of carbapenems as initial antibiotics on mortality rates in critically ill patients with bacterial infections, utilizing data from 268 patients across 31 Japanese ICUs.
- Results showed no significant difference in 28-day mortality between patients treated with carbapenems and those who were not (18% vs 16%).
- However, a longer duration of carbapenem use was associated with an increased risk of detecting multidrug-resistant pathogens.
(233/250) Retinal vein occlusion (RVO) causes macular edema and retinal ischemia resulting in visual field and vision loss. A bispecific antibody that blocks VEGF-A and angiopoietin-2 (Ang-2) has been recently launched and applied clinically to treat macular edema, but the role of Ang-2 in the pathogenesis of RVO is still unclear. In this study, we investigated the effects of the anti-VEGF-A/anti-Ang-2 bispecific antibody (BsAb) in a murine RVO model.

Article Synopsis
- - The Dobbs v. Jackson decision by the U.S. Supreme Court in June 2022 removed federal protections for abortion, raising concerns about reproductive rights and the use of health data in research.
- - This study analyzed data from a preconception cohort study, focusing on participant engagement before and after the Dobbs ruling, particularly in relation to their state's abortion access.
- - Results showed that in states with banned or restricted abortion rights, there was a significant 27.12 percentage point drop in participants clicking on a fertility-tracking app compared to states with limited or protected rights, indicating a decrease in engagement linked to the Dobbs decision.
Article Synopsis
- Dysphagia, or difficulty swallowing, is common in critically ill patients, and various rehabilitation methods are used globally to treat it.
- A review of randomized controlled trials found that dysphagia rehabilitation reduced the risk of pneumonia but did not significantly affect mortality or health-related quality of life.
- The analysis included 19 trials with over 1,000 participants, indicating moderate certainty that rehabilitation helps with pneumonia but very low certainty concerning its effects on mortality and quality of life.
Introduction And Importance: Infections of inferior vena cava (IVC) filters are rare. The authors present a case of IVC filter infection following concurrent emphysematous urinary tract infections that was finally treated with prolonged suppressive antibiotic therapy (PSAT).
Case Presentation: A 68-year-old man with pemphigoid and type 2 diabetes mellitus, who had undergone IVC filter placement, was transferred with decreased consciousness, respiratory failure, and hypotension.
Background: Stent-graft placement is generally used to treat pseudoaneurysm (PSA) of the axillary artery (AA) trunk to maintain the patency of peripheral vessels. Coil embolization of a PSA associated with a disrupted AA trunk has rarely been reported.
Case Presentation: A 54-year-old woman presented with swelling of her right shoulder.
Background: Dietary factors, including high sugar intake, may have adverse effects on male reproduction. Studies of the association between sugar-sweetened beverage (SSB) intake and semen quality have reported inconsistent results.
Objective: We estimated the effects of SSB consumption on semen quality in a North American preconception cohort study.
Article Synopsis
- The study evaluates how pediatric patients with severe blunt pancreatic injuries are managed across different types of trauma centers (pediatric, mixed, and adult) from 2011 to 2021.
- It found that there is a significant increase in the use of nonoperative management (NOM) and endoscopic retrograde cholangiopancreatography (ERCP) during this period, particularly in pediatric and mixed centers.
- Importantly, there was no increase in in-hospital mortality, indicating that these management trends are safe and effective.
Background: During the COVID-19 pandemic, numerous issues regarding end-of-life care for COVID-19 patients have been discussed. Among these issues, challenges related to the use of body bags following the death of COVID-19 patients have been suggested. This study aimed to identify the challenges faced by healthcare professionals (HCPs) when using body bags after the death of patients infected with COVID-19 in medical settings.

Methods: A nationwide web-based survey conducted in early 2023 targeted emergency physicians working a minimum of 3 days per week in Japan.
Article Synopsis
- - This study investigated the relationship between the severity of contrast extravasation (CE) seen on CT scans and the need for massive transfusions (MT) in children with blunt liver and/or spleen injuries, over a span from 2008 to 2019.
- - The research included 1,407 pediatric patients, revealing that 14% required MT, and specific types of CE, particularly intraparenchymal and into the peritoneal cavity, significantly correlated with increased transfusion needs.
- - The findings suggest that recognizing active CE during initial CT scans can guide healthcare providers in making informed decisions about transfusion strategies for young patients with these types of injuries.
Background: Buprenorphine is effective for the treatment of opioid use disorder and chronic pain, has a safer pharmacological profile than full mu-opioid agonists, and can now be prescribed by any US provider with a Drug Enforcement Administration license. This study aimed to examine a decade of buprenorphine prescribing patterns in the United States.
Methods: We abstracted opioid and buprenorphine prescribing patterns, including patient characteristics, from the 2010-2019 National Ambulatory Medical Care Survey, a national probability sample of non-federal, ambulatory encounters.
Background: Burnout is common and can lead to worse outcomes for both healthcare workers and patients. Our study purpose was to assess the structural relationship among factors that protect against or worsen burnout.
Data Sources And Study Setting: We surveyed healthcare professionals in 15 different Japanese intensive care units during the 3rd wave of the COVID-19 pandemic (March 2021).
Providing standardized, high-quality rehabilitation for critically ill patients is a crucial issue. In 2017, the Japanese Society of Intensive Care Medicine (JSICM) promulgated the "Evidence-Based Expert Consensus for Early Rehabilitation in the Intensive Care Unit" to advocate for the early initiation of rehabilitations in Japanese intensive care settings. Building upon this seminal work, JSICM has recently conducted a rigorous systematic review utilizing the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology.

Patients And Methods: We prospectively enrolled patients with suspected myocardial infarction without ST-segment elevation from nine emergency departments in Japan. The diagnostic algorithms evaluated: (i) based on hs-cTnI alone, such as the European Society of Cardiology (ESC) 0/1-h or 0/2-h and High-STEACS pathways; or (ii) used medical history and physical findings, such as the ADAPT, EDACS, HEART, and GRACE pathways.
The percentage cross-sectional area of the lung under five (%CSA) is the percentage of pulmonary vessels with <5 mm area relative to the total lung area on computed tomography (CT). The extent that %CSA is related to pulmonary hemodynamics in patients with chronic thromboembolic pulmonary hypertension (CTEPH) is unclear, as is the effect of pulmonary endarterectomy (PEA) on %CSA. Therefore, we aimed to evaluate the clinical significance of %CSA in patients with CTEPH.

- - Tube thoracostomy, while generally safe, can occasionally lead to serious bleeding complications from vascular injuries in the chest wall, particularly involving less commonly recognized arteries like the thoracodorsal artery.
- - A case study detailed a 58-year-old man with liver cirrhosis who developed a spontaneous hemopneumothorax and faced complications including ongoing bleeding after chest tube placement due to an injury to the thoracodorsal artery.
- - Emergency physicians need to be cautious as the thoracodorsal artery supplies muscles in the chest area where tubes are often placed, indicating that even in the "triangle of safety," serious bleeding can still occur, necessitating careful monitoring post-procedure. *
