Background: The clinical impact of bariatric surgery (BS) prior to pancreas transplantation (PTx) is unclear.
Setting: University of Minnesota Hospital, Minneapolis, MN.
Methods: This was a single center retrospective case-controlled study of all patients January 1, 1998 and May 1, 2024 with a history of BS prior to PTx.
Article Synopsis
- A study investigated the global prevalence of Long Covid symptoms in individuals from high-income countries (HICs) and low- to middle-income countries (LMICs), since most previous research focused on HICs.
- The research involved 11,860 participants from 17 countries, examining symptoms like fatigue, breathlessness, and their impact on daily life at various time points after hospitalization.
- Findings revealed a significantly higher proportion of Long Covid cases and associated symptoms in HICs compared to LMICs, suggesting that while LMICs have lower reported rates, the overall impact of Long Covid might still be significant due to healthcare disparities.
The UK Overseas Territories (UKOTs) are small, often remote territories with historical and territorial links to the UK. They range from densely populated areas (Cayman, Bermuda, Gibraltar) to land with no permanent inhabitants (British Antarctic Territory, South Georgia). However, they are linked by ecosystem instability (the permacrisis) including antimicrobial resistance (AMR), climate change and biodiversity disruption.

- The study evaluated the effectiveness of three different isoxazoline-containing acaricides (sarolaner, afoxolaner, and lotilaner) in killing the tick Amblyomma americanum, with a focus on how quickly they work after being administered to beagle dogs.
- Lotilaner showed a significant speed of kill within 12 hours of infestation, outperforming both sarolaner and afoxolaner at various time points through the study.
- Over time, the efficacy of sarolaner and afoxolaner decreased, while lotilaner maintained higher effectiveness levels, suggesting it is the most reliable option among the three for reducing tick infestations.
Systemic manipulations that enhance dopamine (DA) transmission around the time of fear extinction can strengthen fear extinction and reduce conditioned fear relapse. Prior studies investigating the brain regions where DA augments fear extinction focus on targets of mesolimbic and mesocortical DA systems originating in the ventral tegmental area, given the role of these DA neurons in prediction error. The dorsal striatum (DS), a primary target of the nigrostriatal DA system originating in the substantia nigra (SN), is implicated in behaviors beyond its canonical role in movement, such as reward and punishment, goal-directed action, and stimulus-response associations, but whether DS DA contributes to fear extinction is unknown.
