Bubonic plague was transmitted to a 10-year-old girl in Oregon by a scratch wound inflicted by a domestic cat. The cat probably was infected by contact with infected wild rodents or their fleas. Yersinia pestis was identified in Diamanus montanus fleas collected from an abandoned burrow near the patient's home. Domestic cats may infect humans with Y pestis by inoculation from a scratch.

Renal tubular acidoses (RTAs) are a subset of non-anion gap metabolic acidoses that result from complex disturbances in renal acid excretion. Net acid excretion is primarily accomplished through the reclamation of sodium bicarbonate and the buffering of secreted protons with ammonia or dibasic phosphate, all of which require a series of highly complex and coordinated processes along the renal tubule. Flaws in any of these components lead to the development of metabolic acidosis and/or a failure to compensate fully for other systemic acidoses. Identification and diagnosis of RTA can be challenging, and the consequences of untreated RTA can be life-threatening. The use of serum and urinary indices can help elucidate the kidney's capacity to respond to acidemia, characterize these disturbances further, and guide treatment.

Hemorrhagic complications associated with regional anesthesia are extremely rare. The fifth edition of the American Society of Regional Anesthesia and Pain Medicine's Evidence-Based Guidelines on regional anesthesia in the patient receiving antithrombotic or thrombolytic therapy reviews the published evidence since 2018 and provides guidance to help avoid this potentially catastrophic complication.The fifth edition of the American Society of Regional Anesthesia and Pain Medicine's Evidence-Based Guidelines on regional anesthesia in the patient receiving antithrombotic or thrombolytic therapy uses similar methodology as previous editions but is reorganized and significantly condensed. Therefore, the clinicians are encouraged to review the earlier texts for more detailed descriptions of methods, clinical trials, case series and pharmacology. It is impossible to perform large, randomized controlled trials evaluating a complication this rare; therefore, where the evidence is limited, the authors continue to maintain an 'antihemorrhagic' approach focused on patient safety and have proposed conservative times for the interruption of therapy prior to neural blockade. In previous versions, the anticoagulant doses were described as prophylactic and therapeutic. In this version, we will be using 'low dose' and 'high dose,' which will allow us to be consistent with other published guidelines and more accurately describe the dose in the setting of specific patient characteristics and indications. For example, the same 'high' dose may be used in one patient as a treatment for deep venous thrombosis (DVT) and in another patient as prophylaxis for recurrent DVT. Due to the increasing ability to obtain drug-specific assays, we have included suggestions for when ordering these tests may be helpful and guide practice. Like previous editions, at the end of each recommendation the authors have clearly noted how the recommendation has changed from previous editions.

Approximately half of critically ill adults experience intensive care unit acquired weakness (ICUAW). Patients who develop ICUAW may have negative outcomes, including longer duration of mechanical ventilation, greater length of stay, and worse mobility, physical functioning, quality of life, and mortality. Early physical rehabilitation interventions have potential for improving ICUAW; however, randomized trials show inconsistent findings on the efficacy of these interventions. This review summarizes the latest evidence on the definition, diagnosis, epidemiology, pathophysiology, risks factors, implications, and management of ICUAW. It specifically highlights research gaps and challenges, with considerations for future research for physical rehabilitation interventions.

Gastroesophageal reflux disease (GERD) affects millions globally, with traditional treatments like proton pump inhibitors (PPIs) and surgical fundoplication presenting challenges such as long-term medication dependency and disturbing long term side effects following surgery. This review explores emerging, alternative therapies that offer less invasive, personalized alternatives for GERD management. Endoscopic approaches, including Stretta therapy, transoral incisionless fundoplication (TIF), and endoscopic full-thickness plication (EFTP), demonstrate promising but also controversial outcomes in symptom relief and reduced acid exposure. Laparoscopic electrical stimulation therapy (EndoStim&#xae; ) and the LINX&#xae; magnetic sphincter augmentation system address LES dysfunction, while endoscopic anti-reflux mucosectomy and/or ablation techniques aim to construct a sufficient acid barrier. The RefluxStop&#x2122; device offers structural solutions to GERD pathophysiology with intriguing results in initial studies. Despite promising results, further research is required to establish long-term efficacy, safety, and optimal patient selection criteria for these novel interventions. This review underscores the importance of integrating emerging therapies into a tailored, multidisciplinary approach to GERD treatment.

Marathon training and running have many beneficial effects on human health and physical fitness; however, they also pose risks. To date, no comprehensive review regarding both the benefits and risks of marathon running on different organ systems has been published.

The aim of this review was to provide a comprehensive review of the benefits and risks of marathon training and racing on different organ systems. A predefined search strategy including keywords (e.g., marathon, cardiovascular system, etc.) and free text search was used. Articles covering running regardless of sex, age, performance level, and event type (e.g., road races, mountain marathons) were considered, whereas articles examining only cycling, triathlon, stress-tests or other sports were excluded. In total, we found 1021 articles in PubMed, Scopus, and Google Scholar, of which 329 studies were included in this review. Overall, marathon training offers several benefits for different organ systems and reduces all-cause mortality. As such, it improves cardiovascular risk factors, leads to favorable cardiac adaptations, enhances lung function, and improves quality of life in chronic kidney disease patients. It also enhances gastrointestinal mobility and reduces the risk of specific tumors such as colorectal cancer and hepatocellular carcinoma. Marathon training enhances bone health and skeletal muscle metabolism. It further positively affects hematopoiesis and cytotoxic abilities of natural killer cells, and may act neuroprotective on a long-term basis. After a marathon, changes in biomarkers suggesting pathological events in certain organ systems such as cardiovascular, renal, gastrointestinal, liver, hematological, immune, musculoskeletal, central nervous, and endocrine systems can often be observed. Mostly, these changes are limited to 1-3 days post-race and usually normalize within a week. Moreover, marathon running poses the risk of serious adverse events such as sudden cardiac death or acute liver failure. Concerning lung function, a decrease after a marathon race was observed. Acute kidney injury, as well as electrolyte imbalances, are relatively common amongst marathon finishers. Many runners complain of gastrointestinal symptoms during or after long-distance running. Many runners suffer from running-related musculoskeletal injuries often impairing performance. A marathon is often accompanied by an acute inflammatory response with transient immunosuppression, making runners susceptible to infections. Also, hormonal alterations such as increased cortisol levels or decreased testosterone levels immediately after a race are observed. Disturbances in sleep patterns are commonly found in marathon runners leading up to or directly after the race.

All in all, marathon training is generally safe for human health and individual organ systems. Considering the high popularity of marathon running, these findings supply athletes, coaches, sports scientists, and sports medicine practitioners with practical applications. Further large-scale studies examining long-term effects on the cardiovascular, renal, and other system are needed.

Gallstone disease is a common gastrointestinal disorder in industrialised societies. The prevalence of gallstones in the adult population is estimated to be approximately 10-15%, and around 80% remain asymptomatic. At present, cholecystectomy is the default option for people with symptomatic gallstone disease.

To assess the clinical and cost-effectiveness of observation/conservative management compared with laparoscopic cholecystectomy for preventing recurrent symptoms and complications in adults presenting with uncomplicated symptomatic gallstones in secondary care.

Parallel group, multicentre patient randomised superiority pragmatic trial with up to 24 months follow-up and embedded qualitative research. Within-trial cost-utility and 10-year Markov model analyses. Development of a core outcome set for uncomplicated symptomatic gallstone disease.

Adults with symptomatic uncomplicated gallstone disease referred to a secondary care setting were considered for inclusion.

Participants were randomised 1: 1 at clinic to receive either laparoscopic cholecystectomy or observation/conservative management.

The primary outcome was quality of life measured by area under the curve over 18 months using the Short Form-36 bodily pain domain. Secondary outcomes included the Otago gallstones' condition-specific questionnaire, Short Form-36 domains (excluding bodily pain), area under the curve over 24 months for Short Form-36 bodily pain domain, persistent symptoms, complications and need for further treatment. No outcomes were blinded to allocation.

Between August 2016 and November 2019, 434 participants were randomised (217 in each group) from 20 United Kingdom centres. By 24 months, 64 (29.5%) in the observation/conservative management group and 153 (70.5%) in the laparoscopic cholecystectomy group had received surgery, median time to surgery of 9.0 months (interquartile range, 5.6-15.0) and 4.7 months (interquartile range 2.6-7.9), respectively. At 18 months, the mean Short Form-36 norm-based bodily pain score was 49.4 (standard deviation 11.7) in the observation/conservative management group and 50.4 (standard deviation 11.6) in the laparoscopic cholecystectomy group. The mean area under the curve over 18 months was 46.8 for both groups with no difference: mean difference -0.0, 95% confidence interval (-1.7 to 1.7); p -value 0.996; n &#x2005;=&#x2005;203 observation/conservative, n &#x2005;=&#x2005;205 cholecystectomy. There was no evidence of differences in quality of life, complications or need for further treatment at up to 24 months follow-up. Condition-specific quality of life at 24 months favoured cholecystectomy: mean difference 9.0, 95% confidence interval (4.1 to 14.0), p &#x2005;&lt;&#x2005;0.001 with a similar pattern for the persistent symptoms score. Within-trial cost-utility analysis found observation/conservative management over 24 months was less costly than cholecystectomy (mean difference -&#xa3;1033). A non-significant quality-adjusted life-year difference of -0.019 favouring cholecystectomy resulted in an incremental cost-effectiveness ratio of &#xa3;55,235. The Markov model continued to favour observation/conservative management, but some scenarios reversed the findings due to uncertainties in longer-term quality of life. The core outcome set included 11 critically important outcomes from both patients and healthcare professionals.

The results suggested that in the short term (up to 24 months) observation/conservative management may be a cost-effective use of National Health Service resources in selected patients, but subsequent surgeries in the randomised groups and differences in quality of life beyond 24 months could reverse this finding. Future research should focus on longer-term follow-up data and identification of the cohort of patients that should be routinely offered surgery.
