Background And Objectives: Falling asleep while feeding (FAF) infants is common. Our primary objectives were to examine (1) maternally reported prevalence of FAF and if planned; (2) association between FAF and sociodemographic factors, feeding method, and sleep location; and (3) if receipt of education about safe sleep and bedsharing risks was associated with FAF.

Methods: In the Social Media and Risk-reduction Training study, US mothers of newborns were randomized to educational messaging promoting infant safe sleep or breastfeeding.

Article Synopsis
  • The study focused on understanding unsatisfactory outcomes that need further interventions after the Oblique Lateral Interbody Fusion (OLIF) procedure, which stabilizes the spine and relieves nerve pressure.
  • Conducted from June 2016 to March 2023, the research involved 231 patients and found that 12.1% required reintervention, primarily due to adjacent segment disease (ASD).
  • Key risk factors for needing additional surgery included having previous spine surgeries and higher preoperative disability scores, with longer follow-up periods suggesting a potential increase in reintervention risk.

Carbon-based molecules are of universal importance for a huge variety of chemical and biological processes. The complication of the structure of such molecules proceeds via the bonding of carbon atoms. An efficient mechanism for such reactions proceeds via cross-coupling, related to the association of bond-terminating counter-ions.

Sofosbuvir/Velpatasvir (SOF/VEL) is a combination drug used for chronic hepatitis C (HCV) infection. However, limited information exists regarding the pharmacokinetics of SOF/VEL and its metabolites in hemodialysis patients. We conducted a prospective investigation of the pharmacokinetic parameters of SOF/VEL after a single dose of SOF/VEL (400/100 mg) on days with and without dialysis in 12 Thai hemodialysis patients with chronic HCV infection, who had been undergoing hemodialysis for a duration of 0.

  • MSM living with HIV have a higher risk for anal cancer, particularly due to precursor lesions called high-grade squamous intraepithelial lesions (HSILs), but the incidence among those starting antiretroviral therapy during acute HIV has not been well studied.* -
  • In a study of 89 MSM and 4 transgender women in Bangkok, 11.8% were found to have anal HSIL at the start, with an incidence rate of 19.7 per 100 person-years, influenced by factors like specific HPV types and syphilis.* -
  • The study concluded that while the prevalence of anal HSIL was similar among those initiating treatment during acute HIV and those without HIV, ongoing screening and management

Article Synopsis
  • Non-sputum-based tests are crucial for diagnosing tuberculosis (TB) in people living with HIV (PWH), and the Kyn-to-Trp (K/T) plasma ratio may serve as a promising biomarker to predict TB disease in these patients on antiretroviral therapy (ART).
  • The study measured K/T ratios at three different time points (at diagnosis, 6 months before, and 6 months after) in PWH who developed TB, revealing significantly higher ratios at diagnosis compared to matched controls.
  • Following successful TB treatment, K/T ratios significantly dropped, but they increased in cases of treatment failure, suggesting the ratio could be useful for monitoring TB treatment in PWH, pending further validation studies.

  • The study investigates how maternal responsiveness and self-regulation mediate the link between a mother's education level and her child's self-regulation skills.
  • It involved 189 mother-child pairs and used various scales to assess maternal emotional regulation, responsiveness, and child self-regulation.
  • Results showed that higher maternal education correlated with better child self-regulation, largely due to increased maternal responsiveness, which accounted for 29% of the effect.

Introduction: Immune dysregulation persists in people with HIV (PWH) on antiretroviral therapy (ART) and may lead to accelerated vascular ageing and cardiovascular disease (CVD). While delayed time to initiation of ART has been linked to worse cardiovascular outcomes, the effect of ART initiation during acute infection on these outcomes is not well understood.

Methods: Participants were enrolled from the SEARCH010/RV254 acute HIV (AHI) and HIV-NAT chronic HIV (CHI) cohorts in Thailand.

Background: ON-freezing of gait (ON-FOG) in Parkinson's disease (PD), often resistant to medication, is linked to sensory deficits and proprioceptive impairment, and results in falls and reduced life quality. While visual cues from a laser cane (LC), which rapidly accesses the motor cortex, are commonly used to compensate for proprioceptive impairment, increased visual reliance may be affected by disease progression. Emerging evidence suggests that modulation of peripheral sensory processing may alleviate ON-FOG, and therapeutic Thai acupressure (TTA) may be a solution.
