Objective: The Pediatric Emergency Care Applied Research Network (PECARN) derived and externally validated a clinical prediction rule to identify children with blunt torso trauma at low risk for intraabdominal injuries undergoing acute intervention (IAI). Little is known about the risk for IAI when only one or two prediction rule variables are positive. We sought to determine the risk for IAI when either one or two PECARN intraabdominal injury rule variables are positive.

Background: Few studies have investigated associations between per- and polyfluoroalkyl substances (PFAS) and childhood cancers. Detectable levels of PFAS in California water districts were reported in the Third Unregulated Contaminant Monitoring Rule for 2013-2015.

Methods: Geocoded residences at birth were linked to corresponding water district boundaries for 10,220 California-born children (aged 0-15 years) diagnosed with cancers (2000-2015) and 29,974 healthy controls.

Background And Aims: Elevated lipoprotein(a) [Lp(a)], high-sensitivity C-Reactive Protein (hs-CRP), and total homocysteine (tHcy) are associated with atherosclerotic cardiovascular disease (ASCVD) risk. This study investigated the individual and joint associations of Lp(a), hs-CRP and tHcy with coronary heart disease (CHD) and stroke.

Methods: This study was conducted in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort (2000-2017) (CHD analytic = 6,676; stroke analytic = 6,674 men and women).

Background: Declining motor abilities might be a noninvasive biomarker for Alzheimer's disease (AD). Studying motor ability and AD progression in younger Latinos with autosomal dominant Alzheimer's disease (ADAD) can provide insights into the interplay between motor ability and cognition in individuals with minimal confounding from age-normative changes and comorbid medical conditions.

Objectives: This study aimed to (1) examine motor abilities as a function of years to dementia diagnosis and (2) examine associations between motor ability and cognitive performance.

Article Synopsis
  • The human microbiome consists of microorganisms like bacteria and fungi that impact health, with imbalances (dysbiosis) linked to diseases such as asthma and obesity.
  • Current research is exploring how the gut microbiome specifically affects joint health and diseases like osteoarthritis through inflammatory responses triggered by dysbiosis.
  • The review aims to enhance our understanding of the microbiome's role in disease and emphasizes the need for further studies on the joint microbiome's impact on conditions like periprosthetic joint infection.

Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.

Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).

Background: Previous studies have shown that people with multiple sclerosis (MS) had frequent healthcare visits up to 10 years before being diagnosed but with no information from magnetic resonance imaging (MRI) scans of the connection with the radiologically isolated syndrome (RIS).

Objective: To analyze healthcare use 3 years before the RIS diagnosis.

Methods: We examined healthcare usage before the first scan in RIS cases from 2010 to 2019.

Circulating glycine levels have been associated with reduced risk of coronary artery disease (CAD) in humans but these associations have not been observed in all studies. We evaluated whether the relationship between glycine levels and atherosclerosis was causal using genetic analyses in humans and feeding studies in mice. Serum glycine levels were evaluated for association with risk of CAD in the UK Biobank.

This review article focuses on acral lentiginous melanoma (ALM), a rare cutaneous malignancy and the least common subtype of cutaneous malignant melanoma (CMM). ALM exhibits distinct characteristics, such as low overall mutation rates and increased chromosomal alterations. It is associated with worse prognosis, more advanced disease, and lower survival rates compared to other CMM subtypes.

With the publication of CALGB 140503, an increase in wedge resections for small, peripheral non-small cell lung cancer is expected; however, a relative paucity of data exists as to what defines a high quality oncologic wedge resection. The Thoracic Surgery Outcomes Research Network (ThORN), through expert discussion, guided by review of what limited data does exist, and through use of a modified Delphi process, provides these consensus statements defining an oncologically sound, high quality wedge resection. The statements are classified into five categories: 1) Preoperative Considerations 2) Technical Aspects 3) Lymph Node Assessment 4) Margin Assessment and 5) Tissue Handling by Pathology.

Primary intrarenal hemangioma - A series of 39 cases.

Ann Diagn Pathol

January 2025

Department of Pathology and Laboratory Medicine, Brigham and Women's Hospital, Boston, USA. Electronic address:

Intrarenal hemangiomas lack concise clinicopathologic information, due to the predominance of single case reports and inclusion of other vascular neoplasms and hemangiomas of perirenal, hilar, and renal vein origin. Herein, in this multi-institutional study we evaluate clinicopathologic features of 39 intrarenal hemangiomas. The median age was 62 years (range = 27-94 years; 2:1 male to female ratio), with left-sided predominance (left = 21, right = 13; one case was bilateral).

Objective: Tumor consistency, or fibrosity, affects the ability to optimally resect meningiomas, especially with recent trends evolving toward minimally invasive approaches. The authors' team previously validated a practical 5-point scale for intraoperative grading of meningioma consistency. The impact of meningioma consistency on surgical management and outcomes, however, has yet to be explored.

Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Objectives: Long-term maintenance of serum urate (SU) levels <6 mg/dl reduces gout flare frequency. However, urate-lowering therapy (ULT) initiation can induce gout flare. The incidence of thromboembolic (TE) and cardiovascular (CV) events has been shown to increase in the 30 and 120 days following gout flare, respectively; therefore, the question of ULT initiation increasing patient risk for CV/TE events has been raised.

The Scenic Route: Lingular Metastasectomy Through the Right Chest.

Ann Thorac Surg Short Rep

September 2024

Division of Thoracic Surgery, Department of Surgery, Yale-New Haven Hospital, New Haven, Connecticut.

Metastasectomy for isolated pulmonary metastasis can improve disease-free and overall-survival in well-selected patients. When feasible, a minimally invasive wedge resection is the preferred approach. However, a hostile ipsilateral chest can hinder surgical resection.

Liver transplant may be necessary to manage infectious complications from severe structural biliary disease. In this report, we describe a 71-year-old woman with history of coil-embolized hepatic artery pseudoaneurysm who subsequently developed biliary obstruction resulting from coil erosion into the common hepatic duct. Resultant complications included recurrent cholangitis, bacteremia, and numerous hepatic abscesses.

THE IMPACT OF MALE CONTRACEPTION ON GLOBAL SEXUAL AND REPRODUCTIVE HEALTH AND RIGHTS.

Contraception

January 2025

UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP) Department of Sexual and Reproductive Health and Research (SRH) World Health Organization, Geneva, Switzerland. Electronic address:

The right to health and other health-related human rights are legally binding commitments enshrined in international human rights instruments. While these positions are known and ratified by policy makers, little has been done to actualize men's sexual and reproductive health (SRH) as an integral part of attaining these important global goals. Not addressing men's SRH over and above supporting their female partners sustains the sexual and reproductive risks and burdens that women must bear.
