Review
Idiopathic edema (IE) is a disease that occurs predominantly in women. It is characterized by increasing weight gain of > 1.4 kg from morning to night, increasing edema, increasing truncal and abdominal girth with bloating when assuming an upright position and nocturia that is unrelated to menses. There is an increase in morbidity but not mortality. Increased capillary membrane leakage appears to be the underlying pathophysiologic abnormality that explains the myriad of clinical presentations. We present 2 cases of life-threatening complications of IE that resulted in seizures related to acute hyponatremia in one and extreme postural dizziness and fainting induced by postural hypotension in the other. The first patient was successfully treated with salt restriction, timely use of furosemide and limitation of water intake; the other was successfully treated by use of support hose. Treatment of these patients required a fundamental understanding of the intricate pathophysiological consequences of a leaky capillary membrane, an understanding of Starling forces and detailing the effectiveness of a low salt diet, use of diuretics and limited water intake in one and why support hose would be beneficial in the other patient. Both patients experienced significant physical and emotional benefits that substantially improved quality of life.

INTRODUCTION AND IMPORTANCE
Gallbladder volvulus is a rare surgical disease with clinical manifestations similar to acute acalculous cholecystitis. Diagnosing gallbladder volvulus is critical as delayed surgical intervention in gallbladder volvulus is associated with high morbidity and mortality.
CASE PRESENTATION
A 62-year-old male patient presented to our outpatient department for right upper quadrant pain of one-month duration. Taking into consideration the patient's clinical symptoms, laboratory results, and imaging findings, we diagnosed the patient with acute acalculous cholecystitis and started intravenous antibiotics. After 3 days, the clinical progress was unfavorable, laparoscopic cholecystectomy was performed, and the final diagnosis of gallbladder was done intraoperatively. The postoperative course was uneventful, and the patient was discharged on the second day after surgery.
CLINICAL DISCUSSION
The cause of gallbladder volvulus may be related to abnormal embryological development, resulting in a long mesentery gallbladder and consequently leading to a floating gallbladder. Patients with gallbladder volvulus often do not exhibit specific signs, and the symptoms typically resemble those of acute acalculous cholecystitis. Once gallbladder volvulus is diagnosed, the surgical intervention must be conducted immediately.
CONCLUSION
Gallbladder volvulus is a relatively rare and challenging condition to diagnose. It should be considered in cases of acute acalculous cholecystitis, especially in elderly, thin patients who do not respond to antibiotic treatment. Cholecystectomy is the definitive treatment for gallbladder volvulus. In particular, laparoscopic surgery should be chosen initially.

INTRODUCTION
Firearm-related suicides among children present a significant public health concern and a tragic loss of young lives. This study explores the relationship between firearm-related suicides, gun ownership, and state-specific gun laws.
METHODS
This retrospective cohort study collected data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research on children under 18 who died by firearm-related suicides between 2009 and 2016 in all 50 states and D.C. It also utilized data from the RAND State-Level Estimates of Household Firearm Ownership. The study focused on the rate of child firearm suicide deaths per 100,000 individuals. The key variable of interest was the percentage of guns owned per household in each state. Univariable analysis was conducted to examine the association between individual gun laws and child firearm suicide mortalities, while multivariable regression, adjusting for household gun ownership and significant firearm legislation, was employed to assess connection to child firearm suicide mortality.
RESULTS
From 2009 to 2016, 3903 children died from firearm-related suicides in the United States. In our analysis, 15 out of 44 firearm laws were found to be associated with reducing the rates of firearm suicides among children (P < 0.05). However, multivariable regression showed that higher state gun ownership rates were the primary predictor of increased child fatalities from firearms, with children in such states being 325% more likely to die when analyzing handgun laws and 337% more likely when analyzing long gun laws, as indicated by coefficients of 4.25 and 4.37, respectively. No state laws alone notably improved death rates.
CONCLUSIONS
Gun ownership has a stronger association with child suicide rates than state-specific gun laws. Given the weight of gun ownership, future research should prioritize comprehensive public health initiatives to prevent child firearm-related suicides.

Oxyberberine (OBB) is a significant natural compound, with excellent hepatoprotective properties. However, the poor water solubility of OBB hinders its release and absorption thus resulting in low bioavailability. To overcome these drawbacks of OBB, amorphous spray-dried powders (ASDs) of OBB were formulated. The dissolution, characterizations, and pharmacokinetics of OBB-ASDs formulation were investigated, and its hepatoprotective action was disquisitive in the D-GalN/LPS-induced acute liver injury (ALI) mouse model. The characterizations of OBB-ASDs indicated that the crystalline form of OBB active pharmaceutical ingredients (API) was changed into an amorphous form in OBB-ASDs. More importantly, OBB-ASDs showed a higher bioavailability than OBB API. In addition, OBB-ASDs treatment restored abnormal histopathological changes, improved liver functions, and relieved hepatic inflammatory mediators and oxidative stress in ALI mice. The spray drying techniques produced an amorphous form of OBB, which could significantly enhance the bioavailability and exhibit excellent hepatoprotective effects, indicating that the OBB-ASDs can exhibit further potential in hepatoprotective drug delivery systems. Our results provide guidance for improving the bioavailability and pharmacological activities of other compounds, especially insoluble natural compounds. Meanwhile, the successful development of OBB-ASDs could shed new light on the research process of poorly soluble medicine.

BACKGROUND
Transverse myelitis (TM) is a demyelinating inflammatory disease that presents with motor, sensory, and autonomic dysfunction, which may be acute or subacute. COVID-19-associated TM has been described in a scarce number of patients.
CLINICAL CASE
A 15-year-old previously healthy male patient with respiratory disease before his neurological deterioration presented to the emergency room after developing a complete medullary syndrome located at the cervical-dorsal level, with ascending and symmetric paraparesis that rapidly progressed to paraplegia, with sensory dysfunction from the T3 level, sphincter dysfunction and sudden ventilatory deterioration that required mechanical ventilation. Magnetic resonance imaging was compatible with acute TM. Inflammatory and non-inflammatory etiologies were discarded. In addition, a positive severe acute respiratory syndrome coronavirus 2 test was obtained. Treatment included steroid pulses and plasmapheresis, with an insidious evolution.
CONCLUSION
COVID-19 is an infrequent cause of TM and should be suspected when other etiologies have been ruled out.

Observational Study
BACKGROUND
The worldwide prevalence of arterial hypertension in pediatric patients is 3.5%, and it has repercussions at renal, cardiovascular, neurological, and lifestyle levels. This study aimed to estimate the prevalence of arterial hypertension, mortality, and follow-up in patients with acute renal failure in the nephrology outpatient clinic at a second-level hospital in Northwestern Mexico.
METHODS
We conducted a descriptive, retrospective, and observational study. Men and women aged 1-18 years diagnosed with acute kidney injury were analyzed from January 1, 2012, to December 31, 2021. The medical and electronic records of the candidate patients were analyzed, and nutritional data, laboratory analysis, most frequent etiology, and follow-up in the pediatric nephrology clinic were collected. Those with exacerbated chronic kidney disease and previous diagnosis of high blood pressure were excluded.
RESULTS
One hundred and seventy-four patients were evaluated, and only 40 were eligible for the study (22.98%), predominantly males with a mean age of 9.9 years. The degree of arterial hypertension was 50% for grade I and 50% for grade II (p = 0.007); the mortality rate was 32%. One hundred percent of hypertension cases were controlled at 6 months after discharge (p = 0.000080).
CONCLUSIONS
Our results were similar to those reported in other studies. Follow-up and early detection of arterial hypertension in children need to be strengthened.

serotype a (Hia) has recently emerged as an important cause of invasive disease in the North American Arctic and Sub-Arctic regions, mainly affecting young Indigenous children. In this study, we addressed the question of whether the prevalence of Hia and all in the nasopharynx differed between paediatric populations from regions with high low incidence of invasive Hia disease. Nasopharyngeal specimens from children with acute respiratory tract infections (ARTI) collected for routine diagnostic detection of respiratory viruses were analysed with molecular-genetic methods to identify and serotype . In Nunavut, a region with a high incidence of invasive Hia disease, all and particularly Hia were found in the nasopharynx of 60.6% and 3.0% children. In Southern Ontario (Hamilton region), where Hia invasive disease is rare, the frequencies of all and Hia detection were 38.5% and 0.6%, respectively. In both cohorts, non-typeable was prevalent (57.0% and 37.9%, respectively). Considering that Hia is an important cause of severe invasive disease in Nunavut children, 3% prevalence of Hia among children with ARTI can reflect continuing circulation of the pathogen in the Northern communities that may result in invasive disease outbreaks.

BACKGROUND
Acute pancreatitis (AP) is a common emergency condition with high morbidity, mortality, and socio-economic impact. Soluble urokinase plasminogen activator receptor (suPAR) is a potential biomarker for AP prognosis. This study systematically reviews the literature on suPAR's prognostic roles in assessing AP severity, organ failure, mortality, and other pathological markers.
METHODS
A comprehensive search of 5 databases up to March 19, 2023, was conducted, selecting cohort studies that examined suPAR's relationship with AP outcomes. Outcome variables included AP severity, organ failure, mortality, hospital stay length, and suPAR's association with other inflammatory markers. Our paper has been registered on Prospero (ID: CRD42023410628).
RESULTS
Nine prospective observational studies with 1033 AP patients were included. Seven of eight studies found suPAR significantly elevated in severe acute pancreatitis (P < .05). Four studies showed suPAR effectively predicted organ failure risk, and 4 studies concluded suPAR significantly predicted mortality (P < .05). The review had no high-risk studies, enhancing credibility.
CONCLUSION
suPAR is a valuable prognostic marker in AP, significantly predicting severity, organ failure, hospital stay length, and mortality. Further large-scale studies are needed to explore suPAR's role in other clinical outcomes related to AP disease course, to establish it as a mainstay of AP prognosis.

One-year mortality and readmission risks following hospitalization for acute exacerbation of chronic obstructive pulmonary disease based on the types of acute respiratory failure: An observational study.
Few studies have examined the risk factors associated with the type of acute respiratory failure (ARF) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). This study evaluated the clinical characteristics and prognosis of patients hospitalized for acute exacerbation of COPD based on the type of ARF. The medical charts of hospitalized patients with acute exacerbation of COPD between 2016 and 2021 were retrospectively reviewed. We classified ARF into 2 types: type 1 ARF with PaO2 < 60 mm Hg in room air or a ratio of arterial partial pressure to fractional inspired oxygen < 300, and type 2 ARF with PaCO2 > 45 mm Hg and arterial pH < 7.35. A total of 435 patients were enrolled in study, including 170 participants without ARF, 165 with type 1 ARF, and 100 with type 2 ARF. Compared with the non-ARF group, the frequency of high-flow nasal cannula, noninvasive ventilation, intensive care unit admissions, and in-hospital deaths was higher in the ARF group compared with the non-ARF group. The ARF group had higher 1-year mortality group (hazard ratio [HR], 2.809; 95% confidence interval [CI], 1.099-7.180; P = .031) and readmission within 1-year rates (HR, 1.561; 95% CI, 1.061-2.295; P = .024) than the non-ARF group. The type 1 ARF group had a higher risk of 1-year mortality (HR, 3.022; 95% CI, 1.041-8.774; P = .042) and hospital readmission within 1-year (HR, 2.053; 95% CI, 1.230-3.428; P = .006) compared with the non-ARF group. There was no difference in mortality and readmission rates between the type 1 and type 2 ARF groups. In conclusion, patients with type 1 ARF rather than type 2 ARF had higher mortality and readmission rates than those without ARF. The prognoses of patients with type 1 and type 2 ARF were similar.

Plasmodium vivax serological exposure markers (SEMs) have emerged as promising tools for the actionable surveillance and implementation of targeted interventions to accelerate malaria elimination. To determine the dynamic profiles of SEMs in current and past P. vivax infections, we screened and selected 11 P. vivax proteins from 210 putative proteins using protein arrays, with a set of serum samples obtained from patients with acute P. vivax and documented past P. vivax infections. Then we used a murine protein immune model to initially investigate the humoral and memory B cell response involved in the generation of long-lived antibodies. We show that of the 11 proteins, especially C-terminal 42-kDa region of P. vivax merozoite surface protein 1 (PvMSP1-42) induced longer-lasting long-lived antibodies, as these antibodies were detected in individuals infected with P. vivax in the 1960-1970s who were not re-infected until 2012. In addition, we provide a potential mechanism for the maintenance of long-lived antibodies after the induction of PvMSP1-42. The results indicate that PvMSP1-42 induces more CD73+CD80+ memory B cells (MBCs) compared to P. vivax GPI-anchored micronemal antigen (PvGAMA), allowing IgG anti-PvMSP1-42 antibodies to be maintained for a long time.
