Autoimmune polyglandular syndromes (APS) are characterized by associations of two or more autoimmune diseases (AID). APS type 3 is characterized by the presence of autoimmune thyroid disease associated with other AID, excluding adrenal gland involvement. Here we report a case of a 64-year-old male, with history of type 1 diabetes mellitus (T1DM), diagnosed at the age of 32, who was referred to a Diabetes consultation in 2014 due to poor metabolic control.

Background: Gastrointestinal (GI) cancers, particularly pancreatic cancer, are characterized by a dense stromal tumor microenvironment where cancer-associated fibroblasts (CAFs) predominate. CAFs comprise highly heterogeneous subpopulations with different functions, which can be both tumor-promoting and tumor-restraining. This systematic review and meta-analysis aims to comprehensively assess the impact of the CAF marker fibroblast-activation protein (FAP) expression on clinical outcomes in GI cancers.

Hemophagocytic lymphohistiocytosis (HLH) is a rare clinical entity characterized by fever, constitutional symptoms, and hepatosplenomegaly associated with the presence of hemophagocytosis in the bone marrow and other organs. Visceral leishmaniasis (VL) is a severe zoonotic disease hypoendemic in Portugal, particularly in the Alto Douro region. We report the case of a 21-year-old female patient with a recent diagnosis of human immunodeficiency virus (HIV) infection, stage C3, in the context of severe pneumonia, who presented to the emergency department with fever, erythematous rash on the upper limbs and trunk, choluria and jaundice, one week after starting antiretroviral therapy (ART).

Spinal cord injury in humans is a life-changing condition with no effective treatment. However, many non-mammalian vertebrates can fully regenerate their spinal cord after injury. Frogs such as Xenopus can regenerate the spinal cord at larval stages, but lose this capacity at metamorphosis.

Spontaneous subcapsular renal hematoma is a rare condition defined as spontaneous hemorrhage confined to the subcapsular and/or perirenal space. Its etiology can vary, ranging from renal tumors to vascular diseases, renal cysts, or infections. Here, we report the case of a 54-year-old male who presented to the emergency department with a two-day history of abdominal pain and fever.

Decades of empirical ecological research have focused on understanding ecological dynamics at local scales. Remote sensing products can help to scale-up ecological understanding to support management actions that need to be implemented across large spatial extents. This new avenue for remote sensing applications requires careful consideration of sources of potential bias that can lead to spurious causal relationships.

Background: Intra- and postoperative hemorrhage is a relevant problem in major abdominal surgery, leading to acute anemia and necessitating transfusion of packed red blood cells. It is estimated that in 30% of abdominal surgeries, intra- or postoperative transfusion is required. Transfusion potentially has detrimental health effects and poses a considerable socioeconomic burden.

Background: At present, there is no standardized method for measuring intraoperative blood loss. Rather, the current data on existing methods is very broad and opaque. In many cases, blood loss during surgery is estimated visually by the surgeon.

Background: Extreme sports have increased in popularity, particularly over the past two decades. Theories explaining participation in extreme sports tend to focus on risk. Consequently, extreme sports participants are often characterized by an accentuated desire for risk and abnormal personal traits, but the positive aspects of extreme sports are often neglected in the literature.

Article Synopsis
  • Neurogenetic disorders linked to mutations in spectrin genes lead to a wide range of symptoms, from peripheral nervous system issues to complex syndromes, emphasizing their diverse impact.
  • An international study identified 14 families with unexplained distal weakness due to heterozygous loss-of-function variants, collecting standardized clinical and imaging data to analyze the condition further.
  • The research found that all 20 patients exhibited early childhood onset of distal weakness with varying severity, along with associated foot abnormalities and muscle changes, confirming the link between these genetic variants and a new syndrome characterized by primarily myogenic effects.

Article Synopsis
  • Human genetics research has made a lot of progress in finding out what causes diseases over the last ten years, thanks to sharing data and working together.
  • The GENESIS platform helps scientists who may not know a lot about bioinformatics to analyze genetics data and discover new disease genes.
  • With over 20,000 datasets from rare disease patients, GENESIS has contributed to discovering more than 100 new genes and helped solve many cases for patients with rare diseases.

Article Synopsis
  • Delayed gastric emptying (DGE) is a common problem after a surgery called pancreatoduodenectomy, and this study looks at how different treatments affect DGE rates.
  • The researchers reviewed 29 studies with 5,930 patients to see if things like surgery techniques, recovery plans, and specific anesthesia methods influenced DGE.
  • The results suggest that removing the pylorus (a part of the stomach), following special recovery protocols, and not using certain feeding tubes can help lower DGE rates after the surgery.

  • CrossFit® combines various activities like weightlifting, gymnastics, and cardio, leading to unique physical demands and physiological responses, which have garnered increasing scientific interest in recent years.
  • A study analyzed 68 relevant papers to determine how different CrossFit workouts affect performance and recovery, finding that specific CrossFit movements are better predictors of success.
  • The study concluded that while individual workouts influence results, the overall benefits align with muscle growth seen in concurrent training, highlighting the need for tailored recovery strategies and further research on workout sessions.

Background: NOTCH3 encodes a transmembrane receptor critical for vascular smooth muscle cell function. NOTCH3 variants are the leading cause of hereditary cerebral small vessel disease (SVD). While monoallelic cysteine-involving missense variants in NOTCH3 are well-studied in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), patients with biallelic variants in NOTCH3 are extremely rare and not well characterised.

DNA-based therapeutics have emerged as a revolutionary approach for addressing the treatment gap in rare inherited conditions by targeting the fundamental genetic causes of disease. Charcot-Marie-Tooth (CMT) disease, a group of inherited neuropathies, represents one of the most prevalent Mendelian disease groups in neurology and is characterized by diverse genetic aetiology. Axonal forms of CMT, known as CMT2, are caused by dominant mutations in >30 different genes that lead to degeneration of lower motor neuron axons.

Charcot-Marie-Tooth (CMT) disease is a neuromuscular disorder affecting the peripheral nervous system. The diagnostic yield in demyelinating CMT (CMT1) is typically ∼80%-95%, of which at least 60% is due to the PMP22 gene duplication. The remainder of CMT1 is more genetically heterogeneous.

Article Synopsis
  • The study investigates the factors affecting the expansion of tandem repeats, focusing on the FGF14 (GAA)·(TTC) repeat locus in a large sample of 2,530 individuals through advanced sequencing techniques.
  • Researchers discovered a prevalent 5'-flanking variant present in over 70% of alleles, which is linked to nonpathogenic alleles and the ancestral lineage of this genetic marker.
  • This common variant is associated with greater stability of the tandem repeat during inheritance and improved accessibility of chromatin, suggesting a role in preventing pathological expansion.

Background: With the continuous advancement of cancer treatments, a comprehensive analysis of the impact of multivisceral oncological pancreatic resections on morbidity, mortality, and long-term survival is currently lacking.

Objective: This manuscript presents the protocol for a systematic review and meta-analysis designed to summarize the existing evidence concerning the outcomes of multivisceral oncological pancreatic resections across diverse tumor entities.

Methods: We will conduct a systematic search of the PubMed or MEDLINE, Embase, Cochrane Library, CINAHL, and ClinicalTrials.
