Background Enterocolitis due to infection (CDI) is one of the most common infectious causes of healthcare-associated diarrhea and a significant cause of morbidity and mortality among hospitalized patients. Gastroesophageal reflux disease (GERD) is notable for its high prevalence, variety of clinical presentations, and underrecognized morbidity. It is widely treated with acid suppression, both with over-the-counter and prescription medications. There are no studies evaluating the impact of GERD on CDI hospitalization. In this study, we aimed to analyze the influence of concomitant GERD on patients hospitalized for CDI enterocolitis. Methodology This was a retrospective, observational study where we extracted data from 2016 to 2020 from the National Inpatient Sample database. We included all patients hospitalized with a primary discharge diagnosis of CDI with or without a secondary diagnosis of GERD. We compared the demographics, comorbidities, and in-hospital outcomes between these two groups. Results This study identified 239,603 hospitalizations with a discharge diagnosis of CDI. Of these, 67,000 (28%) had a concurrent diagnosis of GERD. Patients with GERD had a higher prevalence of hypertension (41% vs. 35.5%, p < 0.01), hyperlipidemia (50% vs. 36.5%, p < 0.01), obesity (13.7% vs. 10.5%, p < 0.01), coronary artery disease (24.4% vs. 19.6%, p < 0.01), and chronic kidney disease (20.7% vs. 19.2%, p < 0.01). Notably, inpatient mortality was lower in CDI hospitalizations with GERD (0.66% vs. 1.46%, p < 0.01). The total hospital charge was reduced in the CDI with GERD group in comparison to the CDI without GERD group (39,599 vs. 43,589, p < 0.01). The length of hospital stay was similar between the two groups (5.3 vs. 5.4 days, p = 0.07). Regarding complications, CDI hospitalizations with GERD demonstrated lower rates of hypovolemic shock (0.5% vs. 0.73%, p = 0.06), septic shock (0.6% vs. 1.05%, p < 0.01), acute kidney injury (1.48% vs. 2.04%, p < 0.01), intestinal perforation (0.008% vs. 0.16%, p = 0.03), and lactic acidosis (0.008% vs. 0.16%, p = 0.03). Conversely, CDI patients with GERD had a higher rate of ileus (2.66% vs. 2.16%, p < 0.01). Conclusions Patients with CDI and concurrent GERD exhibited favorable in-hospital outcomes in terms of complication rates, mortality, and total hospital charges. Further research is required to comprehensively explore and validate these findings.

A burning encephalitis: Fluid-attenuated inversion recovery-hyperintense lesions in Anti-myelin oligodendrocyte glycoprotein-associated encephalitis with seizures in anti-myelin oligodendrocyte glycoprotein-associated encephalitis with seizures-A case report and review of the literature.
FLAMES, or fluid-attenuated inversion recovery-hyperintense lesions in anti-myelin oligodendrocyte glycoprotein (anti-myelin oligodendrocyte glycoprotein)-associated encephalitis with seizures, represents a rarely documented syndrome characterized by ambiguous features. Positioned within the spectrum of inflammatory demyelinating diseases of the central nervous system, it is regarded as a distinct subset of myelin oligodendrocyte glycoprotein antibody-associated disease, the latest classification in this domain. Myelin oligodendrocyte glycoprotein antibody-associated disease exhibits a diverse clinical spectrum, spanning from solitary optic neuritis or myelitis to multifocal central nervous system demyelination, manifesting as acute disseminated encephalomyelitis, or cortical encephalitis accompanied by seizures, delineating the fluid-attenuated inversion recovery-hyperintense lesions in anti-myelin oligodendrocyte glycoprotein-associated encephalitis with seizures syndrome. We present a compelling case study of a 30-year-old individual with a history of recurrent seizures initially diagnosed with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes. However, the disease's progression more closely resembled self-resolving cerebral cortical encephalitis linked with myelin oligodendrocyte glycoprotein antibodies. In addition, we undertake a systematic review of literature cases to explore the diagnostic significance of magnetic resonance angiography, fluid-attenuated inversion recovery, and specialized markers such as diffusion-weighted imaging and perfusion in discerning fluid-attenuated inversion recovery-hyperintense lesions in anti-myelin oligodendrocyte glycoprotein-associated encephalitis with seizures syndrome and elucidating its distinctive characteristics.

BACKGROUND
Patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) usually present with multisystemic dysfunction with a wide range of clinical manifestations. When the tests for common mitochondrial DNA (mtDNA) point mutations are negative and the mtDNA defects hypothesis remains, urine epithelial cells can be used to screen the mitochondrial genome for unknown mutations to confirm the diagnosis.
CASE PRESENTATION
A 66-year-old Chinese woman presented with symptoms of MELAS and was initially misdiagnosed with acute encephalitis at another institution. Although genetic analysis of blood lymphocyte DNA was negative, brain imaging, including magnetic resonance imaging, magnetic resonance spectroscopy, and clinical and laboratory findings, were all suggestive of MELAS. Finally, the patient was eventually diagnosed with MELAS with the mtDNA 5783G>A mutation in the MT-TC gene with a urinary sediment genetic test.
CONCLUSION
This case report expands the genetic repertoire associated with MELAS syndrome and highlights the importance that full mtDNA sequencing should be warranted beside the analysis of classical variants when a mitochondrial disorder is highly suspected. Furthermore, urine sediment genetic testing has played a crucial role in the diagnosis of MELAS.

PURPOSE
The benefits of intraoperative dialysis during orthotopic liver transplantation remain controversial. In patients with anuric renal failure and portopulmonary hypertension, maintaining venous return during caval clamping and unclamping along with minimizing fluid overload is critical to avoiding right ventricular strain and failure.
CLINICAL FEATURES
We present the case of a 54-yr-old female who underwent orthotopic liver transplantation for alcohol-related liver disease with acute decompensation including severe hepatorenal syndrome (anuric requiring dialysis), probable hepatopulmonary syndrome, moderate pulmonary hypertension (right ventricular systolic pressure, 44 mm Hg), hepatic encephalopathy (grade 2), and esophageal varices. Prior to incision, pulmonary arterial pressures were 48/28 (mean, 35) mm Hg with a central venous pressure of 30 mm Hg, cardiac output of 7.4 L·min, and pulmonary vascular resistance of 98 dynes·sec·cm. In the context of right ventricular strain and volume overload observed on transthoracic echocardiography, we inserted an additional dialysis catheter into the right femoral vein. We initiated dialysis using the two catheters as a circuit (femoral line to the dialysis machine; blood was reinjected via the subclavian line) acting as a limited venovenous bypass, allowing right ventricular offloading and hemodialysis throughout the case. We removed 4.5 L via hemodialysis during the surgery, while avoiding acidosis, hyperkalemia, and sodium shifts. The patient tolerated reperfusion adequately despite pre-existing right ventricular dilation and dysfunction.
CONCLUSION
We report on the use two hemodialysis catheters in a patient undergoing orthotopic liver transplantation as a circuit for simultaneous anuric hepatorenal syndrome and moderate pulmonary hypertension with right ventricular dilation and dysfunction. We believe this technique was instrumental in the patient's successful transplant.

BACKGROUND
This study aimed to address the increasing prevalence of cesarean section and the importance of evaluating newborn health through arterial blood gas analysis. Its primary objective was to compare the umbilical cord blood gas levels in newborns delivered through different delivery methods.
METHOD
This retrospective descriptive cross-sectional study included singleton pregnancies with a gestational age between 37 and 42 weeks and infants weighing between 2500 and 4000 g. Newborns with an Apgar score of 7 or higher at 1 and 5 min were included. Umbilical cord blood samples were collected from each newborn for blood gas analysis within 60 min after birth.
RESULT
The study included 340 neonates, with 170 born via caesarean section and 170 born through vaginal delivery. No significant differences were observed in Apgar scores between two groups. ABG analysis showed that vaginally born neonates had lower pH (7.24 ± 0.08 vs. 7.27 ± 0.07, P < 0.001), PCO2 (P = 0.015), and HCO3 (P < 0.001). Cesarean section neonates had higher oxygen saturation (P = 0.007) and pressure of oxygen (P < 0.001), and less negative base excess (P < 0.001). In the subgroup analysis, neonates whose mothers received epidural anesthesia had lower pH (7.23 ± 0.07 vs. 7.25 ± 0.08, P = 0.021) and more negative base excess (P = 0.026). Other parameters of ABG did not differ significantly between the groups (P > 0.05).
CONCLUSION
It has been proven that the mode of delivery, whether it is vaginal or cesarean, as well as the administration of epidural anesthesia during vaginal delivery, have a significant impact on newborns at birth. Newborns delivered vaginally exhibit metabolic acidosis compared to those delivered via cesarean section. Although these differences are statistically significant, they do not have a notable clinical significance, as the average values of the evaluated parameters in both groups fall within the normal range.

Physiological or pathophysiological changes lead to posttranslational changes in the sialic acid content of human serum transferrin (hTf), an essential mediator of iron transport in the human body, resulting in a significantly increased concentration of desialylated hTf. The intrinsic fluorescence quenching upon binding of iron to hTf was successfully modeled using the binding polynomial for two iron-binding sites, allowing measurements in a high-throughput format. Removal of sialic acid residues resulted in a 3-fold increase in iron binding affinity for both sites of hTf at pH 7.4. The pH-dependence of iron binding showed significant differences in equilibrium constants, resulting in a 10-fold increase in binding affinity for desialylated hTf at pH 5.9. The changes in hTf sialylation apparently result in tuning of the stability of the conformational state, which in turn contributes to the stability of the diferric hTf. The observed differences in the conditional thermodynamic equilibrium constants suggest that the desialylated protein has a higher preference for diferric hTf over monoferric hTf species down to pH 6.5, which may also influence the interaction with transferrin receptors that preferentially bind to diferric hTf. The results suggest a link between changes in hTf glycan structure and alterations in iron binding equilibrium associated with tissue acidosis.

Diabetic ketoacidosis (DKA) is a severe complication of diabetes mellitus characterized by hyperglycemia, metabolic acidosis, and ketosis. We present a challenging case of euglycemic DKA secondary to fasting and urinary tract infection with acute renal failure in a 50-year-old woman. Despite normal random blood sugar levels, the patient exhibited clinical signs of DKA, leading to further investigation. High anion gap metabolic acidosis with hyperkalemia and abnormal renal function tests were identified. After hemodialysis, serum ketones were found to be highly positive, confirming the diagnosis. Prompt management led to a complete clinical and laboratory resolution. This case underscores the importance of considering DKA in patients with suggestive symptoms, even with normal blood sugar levels.

BACKGROUND
The beneficial effects of oral supplements with alkalinizing agents in patients with chronic kidney disease (CKD) have been limited to the severe stages. We investigated whether two types of supplements, sodium bicarbonate (SB) and potassium citrate/sodium citrate (PCSC), could maintain renal function in patients with mild-stage CKD.
METHODS
This was a single-center, open-labeled, randomized cohort trial. Study participants with CKD stages G2, G3a, and G3b were enrolled between March 2013 and January 2019 and randomly assigned by stratification according to age, sex, estimated glomerular filtration rate (eGFR), and diabetes. They were followed up for 6 months (short-term study) for the primary endpoints and extended to 2 years (long-term study) for the secondary endpoints. Supplementary doses were adjusted to achieve an early morning urinary pH of 6.8-7.2. We observed renal dysfunction or new-onset cerebrovascular disease and evaluated urinary surrogate markers for renal injury.
RESULTS
Overall, 101 participants were registered and allocated to three groups: standard (n = 32), SB (n = 34), and PCSC (n = 35). Two patients in the standard group attained the primary endpoints (renal stones and overt proteinuria) but were not statistically significant. There was one patient in the standard reduced eGFR during the long-term study (p = 0.042 by ANOVA). SB increased proteinuria (p = 0.0139, baseline vs. 6 months), whereas PCSC significantly reduced proteinuria (p = 0.0061, baseline vs. 1 year, or p = 0.0186, vs. 2 years) and urinary excretion of 8-hydroxy-2'-deoxyguanosine (p = 0.0481, baseline vs. 6 months).
CONCLUSION
This study is the first to report supplementation of PCSC reduced intrarenal oxidative stress in patients with mild-stage CKD.
