RESUMO
OBJECTIVE: We aimed to review the literature on the clinical presentation, renal pathology, treatment, and outcome of renal manifestations in adult-onset Still's disease (AOSD). METHODS: We used PRISMA guidelines for our systematic review and included all English-language original articles from inception till September 15, 2023, on AOSD and kidney involvement in any form. Data on patient demographics, diagnostic criteria, clinical presentation, renal pathology, treatment employed including dialysis, outcome, cause of death were collected and analyzed. RESULTS: The median age at the diagnosis of renal issues was 37, with a higher prevalence among females (58.1%). Among the cases, 28 experienced renal problems after being diagnosed with AOSD, 12 had simultaneous diagnoses of renal issues and AOSD, and in 4 cases, renal problems appeared before AOSD diagnosis. Out of the 44 cases, 36 underwent renal biopsy, revealing various pathology findings including AA amyloidosis (25%), collapsing glomerulopathy (11.4%), thrombotic microangiopathy (TMA) (11.4%), IgA nephropathy (9.1%), minimal change disease (6.8%), and others. Some cases were clinically diagnosed with TMA, proximal tubular dysfunction, or macrophage activation syndrome-related acute kidney injury. Treatment approaches varied, but glucocorticoids were commonly used. Renal involvement was associated with increased mortality and morbidity, with 6 out of 44 patients passing away, 4 progressing to end-stage renal disease (ESRD), and data on 2 cases' outcomes not available. CONCLUSION: Renal manifestations in AOSD are diverse but rarely studied owing to the rarity of the disease. Studies with larger data would be essential to study further on the pathogenesis and implications.

Aging can alter immunity affecting host defense. COVID-19 has the most devastating clinical outcomes in older adults, raising the implication of immune aging in determining its severity and mortality. We investigated biological predictors for clinical outcomes in a dataset of 13,642 ambulatory and hospitalized adult COVID-19 patients, including younger (age < 65, n = 566) and older (age ≥ 65, n = 717) subjects, with in-depth analyses of inflammatory molecules, cytokines and comorbidities. Disease severity and mortality in younger and older adults were associated with discrete immune mechanisms, including predominant T cell activation in younger adults, as measured by increased soluble IL-2 receptor alpha, and increased IL-10 in older adults although both groups also had shared inflammatory processes, including acute phase reactants, contributing to clinical outcomes. These observations suggest that progression to severe disease and death in COVID-19 may proceed by different immunologic mechanisms in younger versus older subjects and introduce the possibility of age-based immune directed therapies.

Hypothenar hammer syndrome (HHS) is a rare vascular disorder leading to ulnar artery thrombosis or aneurysm and causing acute or chronic limb ischemia. The optimal approaches to managing this condition lack a definitive consensus and are essentially empirical, typically necessitating conservative methods for symptomatic relief, with surgical intervention reserved for cases for which conservative measures prove inadequate or when acute limb ischemia ensues. Limited data are available on percutaneous management for this condition. We present the case of a 36-year-old male powerlifter who developed acute digital ischemia due to HHS in the left hand that was managed successfully through an innovative approach using antegrade left brachial artery access and combining percutaneous thrombosuction and intra-arterial thrombolysis. This comprehensive approach resulted in restoration of blood flow and resolution of acute limb ischemia. The patient was subsequently prescribed short-term anticoagulation therapy and remained symptom free at 3 months of follow-up. This innovative strategy challenges traditional surgical approaches in HHS management, underscoring the importance of using minimally invasive techniques as a promising alternative and highlighting potential avenues for further research.
RESUMO
OBJECTIVE: Severe hypoglycemia (blood glucose < 50 mg/dl) in hospitalized patients with diabetes mellitus is associated with poor outcomes such as increased mortality and readmission rates. We study the effects of system based interventions in managing severe hypoglycemia and its impact on outcomes. RESEARCH DESIGN AND METHODS: We performed retrospective review of pre- and post- intervention study to quantify severe hypoglycemia in patients admitted in the general internal medicine wards with primary or secondary diagnosis of diabetes mellitus based on ICD-9 and ICD-10 codes. We implemented multidisciplinary interventions including standardization of treatment, education of in-patient medical teams and physician notification and feedback immediately after severe hypoglycemia. The endpoints were the comparative analysis of incidence of severe hypoglycemia, in-patient mortality rate, 30-day mortality rate, 30-day readmission rate, recovery time from hypoglycemia, time to next glucose measurements, use of standardized treatment and physician notification rate pre-and post-intervention. RESULTS: The incidence of severe hypoglycemia per patient with diabetes was reduced from 9.6% (233/2416) to 5.6% (202/3607) (p<0.001) post-intervention. The in-patient mortality rate in patients with severe hypoglycemia reduced from 4.1% to 0% (p = 0.019), 30-day mortality rate reduced from 9.8% to 3.8% (p = 0.058) post-intervention. 30-day readmission rate was comparable between pre-intervention (31.7%) and post-intervention (29%) (p = 0.60). In comparison, the mortality and readmission rates of all diabetic patients did not reduce during the same observation periods. Recovery time reduced from 116 (83-161) to 75 (57-102) min (p<0.01), time to next glucose measurement reduced from 39.5 (34-48) to 32 (28-35) min (p<0.01), use of standardized treatment improved from 22.7% (53/233) to 72.2% (146/202) (p<0.001) and physician notification rate increased from 29.2 (68/233) to 84.7% (171/202) post-intervention. CONCLUSIONS: Our study shows that multidisciplinary strategies improves the process of early detection and management of severe hypoglycemia and reduce incidence and in-patient mortality rate.

RESUMO
BACKGROUND: Severe hypoglycaemic events (HGEs) in hospitalised patients are associated with poor outcomes and prolonged hospitalization. Systematic, coordinated care is required for acute management and prevention of HGEs; however, studies evaluating quality control efforts are scarce. OBJECTIVE: To investigate the effectiveness of system-based interventions to improve management response to HGEs. METHODS: System-based interventions were designed and implemented following a root cause analysis of HGE in adult patients with diabetes from two general medical wards with the highest incidence of HGE. Interventions included electronic medical record programming for a standardised order set for basal-bolus insulin regimen and hypoglycemia protocol, automated dextrose order, automated MD notification, and recommendation for endocrine consultation after two critical HGEs. The Pyxis MedStation was programmed to alert nurses to recheck blood glucose 15 min after the treatment. A card with the HGE management protocol was attached to each provider's ID badge and educational seminars were given to all providers. MAIN OUTCOMES AND MEASURES: Primary outcomes were to evaluate median time from HGE (glucose <50 mg/dL) to euglycemia (>100 mg/dL), and time from HGE to follow-up finger-stick (FS) testing preintervention and postintervention. Secondary outcomes were cumulative incidence of HGEs, recurrent hypoglycemia, rate of physician notification and use of standardised treatments among adults with diabetes on the two general medical wards. RESULTS: Among hospitalised adults with diabetes and HGE, median time from HGE to euglycemia declined from 225±46 min preintervention to 87±26 min postintervention (p=0.03). Median time from HGE to next FS testing also declined (76±14 min to 28±10 min, p<0.001). Standardised treatment administration for HGE improved significantly from 34% (12/35) to 97% (36/37); physician notification rate improved significantly from 51% (18/35) to 78% (29/37).Among hospitalised adults with diabetes, incidence of HGE decreased from 12% (35/295) over 3 months (preintervention period) to 6% (37/610) over 6 months (postintervention period) (p<0.001), while recurrent HGE did not show significant differences (37% (13/35) to 24% (9/37), p=0.09). CONCLUSIONS: System-based interventions had a clinically important impact on decreasing time from HGE to euglycemia and to next FS testing. This hypoglycemia bundle of care may be applied and tested in other community hospitals to improve patient safety.
RESUMO
Hyponatremia is associated with poor prognosis in left heart failure and liver disease. Its prognostic role in pulmonary arterial hypertension (PAH) is not well defined. We investigated the association between hyponatremia and one-year mortality in two large cohorts of PAH. This study is a secondary analysis evaluating the association between hyponatremia and one-year mortality in patients treated with subcutaneous treprostinil (cohort 1). The results are validated using a PAH registry at a tertiary referral center (cohort 2). Eight-hundred and twenty patients were enrolled in cohort 1 (mean age = 47 ± 14 years) and 791 in cohort 2 (mean age = 55 ± 15 years). Sodium level is negatively correlated with mean right atrial pressure (r = -0.09, P = 0.018; r = -0.089, P = 0.015 in cohorts 1 and 2, respectively). In unadjusted analyses of cohort 1, the sodium level (as a continuous variable) is associated with one-year mortality (hazard ratio = 0.94; P = 0.035). Hyponatremia loses its significance (as a continuous variable and when dichotomized at ≤ 137 mmol/L; P = 0.12) when adjusted for functional class (FC), which is identified as the variable whose presence turns the effect of sodium level into non-significant. Secondary analyses using a cut-off value of < 135 mmol/L showed similar results. These results are validated in cohort 2. Although the sample size for patients with sodium < 130 mmol/L is small (n = 31), severe hyponatremia is associated with higher overall mortality (47% versus 23%; P = 0.01), even when adjusting for age, FC, and baseline 6-min walk distance ( P < 0.001). Although baseline hyponatremia is associated with one-year mortality, it loses its significance when adjusted for FC.
RESUMO
The role of potassium in the progression of cardiovascular disease is complex and controversial. Animal and human data suggest that increases in dietary potassium, decreases in urinary potassium loss, or increases in serum potassium levels through other mechanisms have benefits in several disease states. These include the treatment of hypertension, stroke prevention, arrhythmia prevention, and treatment of congestive heart failure. Recently, the discovery that aldosterone antagonists not only decrease sodium reabsorption and decrease potassium secretion in the nephron, but also decrease pathological injury of such nonepithelial tissues as the myocardium and endothelium, has generated great controversy regarding the actual mechanisms of benefit of these agents. We review the available data and draw conclusions about the relative benefits of modulating potassium balance versus nonrenal effects of aldosterone blockade in patients with cardiovascular disease.

BACKGROUND: Poor communication at hospital discharge can increase the risk of adverse events. The hospital discharge summary is the most common tool for detailing events related to hospitalization in preparation for postdischarge follow-up, yet deficiencies in discharge summaries have been widely reported. Resident physicians are expected to dictate discharge summaries but receive little formal training in this arena. We hypothesized that implementation of an educational program on chart documentation skills would result in improvements in the quality of hospital discharge summaries in a community hospital internal medicine residency program. METHODS: A monthly, 1-hour workshop was launched in August 2007 to provide consistent and ongoing instruction on chart documentation. Guided by a faculty moderator, residents reviewed 2 randomly selected peer chart notes per session using instruments developed for that purpose. After the workshop had been in place for 2 years, 4 faculty members reviewed 63 randomly selected discharge summaries from spring 2007, spring 2008, and spring 2009 using a 14-item evaluation tool. RESULTS: Mean scores for 10 of the 14 individual items improved in a stepwise manner during the 3 years of the study. Items related to overall quality of the discharge summary showed statistically significant improvement, as did the portion of the summaries "carbon copied" to the responsible outpatient physician. CONCLUSIONS: The quality of hospital discharge summaries improved following the implementation of a novel, structured program to teach chart documentation skills. Ongoing improvement was seen 1 and 2 years into the program, suggesting that continuing instruction in those skills was beneficial.

BACKGROUND AND OBJECTIVES: Experimentally elevated potassium causes a clear pattern of electrocardiographic changes, but, clinically, the reliability of this pattern is unclear. Case reports suggest patients with renal insufficiency may have no electrocardiographic changes despite markedly elevated serum potassium. In a prospective series, 46% of patients with hyperkalemia were noted to have electrocardiographic changes, but no clear criteria were presented. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Charts were reviewed for patients who were admitted to a community-based hospital with a diagnosis of hyperkalemia. Inclusion criteria were potassium >/=6 with a concurrent electrocardiogram. Data were abstracted regarding comorbid diagnoses, medications, and treatment. Potassium concentrations were documented along with other electrolytes, pH, creatinine, and biomarkers of cardiac injury. Coincident, baseline, and follow-up electrocardiograms were examined for quantitative and qualitative changes in the QRS and T waves as well as the official cardiology readings. RESULTS: Ninety patients met criteria; two thirds were older than 65, and 48% presented with renal failure. Common medications included beta blockers, insulin, and aspirin; 80% had potassium <7.2. The electrocardiogram was insensitive for diagnosing hyperkalemia. Quantitative assessments of T-wave amplitude corroborated subjective assessments of T-wave peaking; however, no diagnostic threshold could be established. The probability of electrocardiographic changes increased with increasing potassium. The correlation between readers was moderate. CONCLUSIONS: Given the poor sensitivity and specificity of electrocardiogram changes, there is no support for their use in guiding treatment of stable patients. Without identifiable electrocardiographic markers of the risk for complications, management of hyperkalemia should be guided by the clinical scenario and serial potassium measurements.
