The purpose of this review is to explore the relationship between weight loss (WL), specifically reductions in body mass index (BMI), and increases in testosterone levels. Obesity and excess body fat are linked to reduced testosterone levels, which can lead to metabolic dysfunctions, reduced libido, and diminished muscle mass. To attain this purpose, this review will summarize current evidence on how weight reduction interventions, including dietary changes, exercise, and bariatric surgery, affect testosterone production in overweight and obese individuals.

Article Synopsis
  • Harmful algal blooms (HABs), especially those from toxin-producing microalgae like Prorocentrum micans, are a recurring issue in Patagonian fjords, and a significant HB-HAB occurred in Northwest Chilean Patagonia during February-March 2022.
  • Observations showed a dramatic increase in P. micans cell density from low levels in January to a peak of over 8.3 x 10 cells/mL by mid-February, associated with warmer sea temperatures and varying salinity.
  • Satellite images and oceanographic modeling revealed that water currents and temperature variations in the Gulf of Ancud supported the development and maintenance of this harmful algal bloom, indicating a hotspot for both HABs and HB-HAB

Being an extremely high mortality rate condition, cardiac arrest cases have rightfully been evaluated via various studies and scoring factors for effective resuscitative practices and neurological outcomes postresuscitation. This narrative review aims to explore the role of artificial intelligence (AI) in predicting neurological outcomes postcardiac resuscitation. The methodology involved a detailed review of all relevant recent studies of AI, different machine learning algorithms, prediction tools, and assessing their benefit in predicting neurological outcomes in postcardiac resuscitation cases as compared to more traditional prognostic scoring systems and tools.

Mucormycosis is a rare deep fungal infection that develops mainly in immunosuppressed patients, being unusual the gastrointestinal presentation. The adequate treatment consists in rapid and aggressive surgical debridement, along with initial adjuvant treatment with liposomal amphotericin B. Despite recent advances in the management of this disease, the prognosis is poor, with a high mortality rate.

Article Synopsis
  • There has been a global increase in Harmful Algae Blooms (HABs) over recent decades, linked to environmental exploitation, enhanced monitoring, and rising maritime transport.
  • HAB species, such as those causing paralytic shellfish poisoning and producing yessotoxins, pose serious public health and socioeconomic risks.
  • Recent observations in the Biobio region suggest a northward movement of these HABs into more open waters, with studies indicating that factors like deep-water turbulence and the presence of toxic resting cysts could trigger harmful events in the environment.

Article Synopsis
  • Scar tissue formation is a critical part of wound healing but can disrupt tissue function, particularly in cases like uterine scarring from cesarean sections.
  • The research focused on how deep uterine scars contribute to a condition called placenta accreta spectrum (PAS), where invasive cells can lead to serious complications during pregnancy.
  • The study found that scar tissue activates the mechanosensitive ion channel, Piezo1, which triggers inflammatory pathways and draws invasive cells towards the scar, highlighting how scar mechanics can disturb normal tissue interactions and potentially relate to cancer spread.

Numerical modeling offers a valuable alternative to analytical solutions for pumping test analysis. However, little is known about how discretization impacts results accuracy and runtime. This study presents a systematic method for defining the spatiotemporal discretization of pumping test numerical models based on dimensionless parameters.

In late summer and early autumn 2022, an intense bloom of Protoceratium reticulatum-the main yessotoxin (YTX) producer along Chilean coasts and a major threat to artisanal fisheries, the aquaculture industry, and environmental health-was recorded in the Patagonian fjord system. The high YTX levels (>3.75 mg kg) resulted in the first ban of shellfish collection in Chile.

Higher lifetime trauma exposure and increased peritraumatic dissociation (PD) are well-known predictors of Post-Traumatic Stress Disorder (PTSD) symptoms following new trauma (prospective PTSD symptoms). The interplay between those factors, however, is not well established. In this study, we aimed to assess whether PD mediates the influence of lifetime trauma exposure on prospective PTSD symptoms.

The changes in the cell physiology (growth rate, cell size, and cell DNA content), photosynthetic efficiency, toxicity, and sexuality under variable light and nutrient (phosphates) conditions were evaluated in cultures of the dinoflagellate obtained from a red tide in the Ría de Vigo (NW Spain). The cells were grown at low (40 and 150 µE m s), moderate (400 µE m s), and high (800 µE m s) light intensities in a medium with phosphate (P+) and without (P-). Cultures were acclimated to the irradiance conditions for one week, and the experiment was run for ~1 month.

Despite its popularity, evidence of the effectiveness of Psychological First Aid (PFA) is scarce. To assess whether PFA, compared to psychoeducation (PsyEd), an attention placebo control, reduces PTSD and depressive symptoms three months post-intervention. In two emergency departments, 166 recent-trauma adult survivors were randomised to a single session of PFA (= 78) (active listening, breathing retraining, categorisation of needs, assisted referral to social networks, and PsyEd) or stand-alone PsyEd ( = 88).

Article Synopsis
  • A complex brain is essential for the success of vertebrates, but much of what we know about brain evolution comes from living species, leaving knowledge gaps.
  • Fossil evidence from preserved actinopterygian (ray-finned fish) specimens in Brazil provides new insights into neuroanatomical evolution and challenges previous interpretations of ancient brain structures.
  • The study identifies two distinct brain morphotypes, with one showing similarities to modern actinopterygians, including an important brain feature not present in the other morphotype, suggesting a revised understanding of brain evolution in this group of vertebrates.

Consumer nutrition environments are defined as places in which consumers interact with the food they eat; these food choices can impact human and planetary health. Assessment measures for consumer nutrition environments are numerous, and vary widely on what, and how, they assess the food environment. The objective of this scoping review was to synthesize existing evidence on nutrition environment measurements and their capacity to assess nutrient-dense food access and food sustainability capacity.

Under the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA), current federal policy mandates a lifetime ban for individuals with a past felony drug conviction from receiving Supplemental Nutrition Assistance Program (SNAP) and Temporary Assistance for Needy Families (TANF) benefits. Denying nutritional and financial assistance to individuals with a past felony conviction will widen existing structural health inequities, set back individuals' successful re-entry into society, and contribute to recidivism and poorer health outcomes. Therefore, the Society of Behavioral Medicine supports the RESTORE ACT (Re-Entry Support Through Opportunities for Resources and Essentials Act), which would repeal the lifetime ban on receiving SNAP and TANF benefits for individuals convicted of a drug felony.
