An 89-year-old man presents with worsening heart failure

Clinical introduction An 89-year-old man with a history of heart failure with preserved ejection fraction presented with worsening dyspnoea, reduced exercise capacity and peripheral oedema. His medical history was significant for hypertension, paroxysmal atrial fibrillation (AF), chronic obstructive pulmonary disease and Lyme disease (1983). Admission cardiovascular medications included aspirin 75 mg once a day, perindopril 6 mg once a day, furosemide 40 mg two times a day, flecainide 100 mg two times a day and simvastatin 40 mg one a night. On examination, he was normothermic and clinically in heart failure with raised jugular venous pressure, bibasal pulmonary crepitations and oedema up to abdomen. Cardiac markers were negative. Other laboratory tests demonstrated a normocytic anaemia, C reactive protein 18.7 mg/L (0–7.9), urea 19.4 mmol/L (2.8–7.2) and creatinine 162 µmol/L (72–127), which had trended above a baseline of 110 µmol/L for 4 months. Electrolytes including sodium, potassium, magnesium, corrected calcium and inorganic phosphate were within normal range. His admission...

Conclusions Exercise training combined with multinutrient supplementation had a limited effect on ameliorating the adverse musculoskeletal consequences of ADT, likely related to the modest intervention adherence.

Conclusion These findings demonstrate that T2D and HTN attenuate tolerance to uncompensable heat stress (32°C WBGT); however, these chronic diseases do not significantly impact thermal and cardiovascular strain, or the validity of ACIGH recommendations during moderate-intensity work.

In conclusion, awareness of the risk factors associated with IFIS, their detailed preoperative assessment and intraoperative measures and surgical intervention is crucial in addressing IFIS. Lack of awareness can turn a routine, uneventful surgery into one with significant visual morbidity.

Exclusive: NHS launching large trial of approach that could boost number of transplants and their success rateThousands of lives could be saved globally by giving patients a 10p statin before transplants, doctors have said, as the NHS launches the world ’s largest clinical trial in organ donors.The medical breakthrough is predicted to dramatically increase the supply of organs for transplant. Currently, demand for organs vastly exceeds the number available. Every year thousands of people die waiting for a transplant, including hundreds in Britain.Continue reading...

Acute respiratory distress syndrome is a heterogenous syndrome with many etiologies for which there are no definitive pharmacologic treatments, despite decades of research. We explore some adjunctive pharmacologic therapies, including neuromuscular blockade, corticosteroids, and inhaled pulmonary vasodilators. Additionally, we explore some investigative therapies, including Vitamin C, beta-agonists, statins, mesenchymal stromal cells, and granulocyte –macrophage colony stimulating factor. We do discuss the potential role of steroids in acute respiratory distress syndrome with severe acute respiratory syndrome coronav...

The sarcolemmal voltage-gated L-type Ca2+ channel (CaV1.1), also known as the dihydropyridine receptor (DHPR), is encoded by CACNA1S and localized in the T-tubule. During skeletal muscle excitation-contraction coupling (ECC), CaV1.1 activated by membrane depolarizations triggers opening of the sarcoplasmic Ca2+ release channel (RyR1) to release Ca2+ for myofibril contraction. Recently, both recessive and dominant CACNA1S mutations are identified as a cause of a novel congenital myopathy with alternations in calcium homeostasis and impaired ECC.
