Diverse Clinical Manifestations and Challenges of Mucormycosis: Insights From Serial Cases.

Mucormycosis is a severe and potentially life-threatening infection caused by a group of fungi classified as mucormycetes within the scientific order Mucorales. These infections are characterized by rapid and invasive fungal growth, presenting significant treatment challenges. Here we present 5 cases encountered from 2018 to 2022 at the University of Texas Medical Branch in Galveston, Texas, including a novel Apophysomyces species. These cases illustrate the diverse clinical manifestations of mucormycosis, including pulmonary, rhino-cerebral, gastrointestinal, and soft tissue involvement. Our investigation incorporates information provided by a multidisciplinary team of clinical collaborators, emphasizing the findings from radiology, histopathology, and microbiology. Given the escalating global incidence of mucormycosis, it is crucial for clinicians to become familiar with associated clinical findings, comorbidities, and risk factors to facilitate prompt recognition, appropriate diagnostic testing, and timely initiation of treatment.

Wooden Chest Syndrome: A Case Report of Fentanyl-Induced Chest Wall Rigidity.

Wooden chest syndrome (WCS) describes a finding of fentanyl-induced skeletal muscle rigidity causing ventilatory failure. Known primarily to anesthesiology, pulmonary, and critical care fields, WCS is a rare complication that may affect patients of all ages if exposed to intravenous fentanyl, characterized by a patient's inability to properly ventilate. Given the rise of synthetic opioid deaths across the United States in the past decade, an understanding of all of fentanyl's effects on the body is necessary. In this article, we present a case of WCS in a patient with acute respiratory distress syndrome in a 61-year-old female.

Impact of Body Mass Index on COVID-19-Related In-Hospital Outcomes and Mortality.

BACKGROUND: Given the high prevalence of obesity around the globe, patients with coronavirus disease 2019 (COVID-19) are at an increased risk of devastating complications. METHODS: A retrospective cohort study was performed to determine the association of basal metabolic index (body mass index (BMI)) with the need for invasive mechanical ventilation (IMV), dialysis, upgrade to an intensive care unit (ICU) and mortality. Independent t-test and multivariate logistic regression analysis were performed to calculate mean differences and adjusted odds ratios (aORs) with its 95% confidence interval (CI), respectively. RESULTS: A total of 176 consecutive patients with confirmed COVID-19 diagnosis were included. The mean age was 62.2 years, with 51% being male patients. The mean BMI for non-surviving patients was significantly higher compared to patients surviving on the seventh day of hospitalization (35 vs. 30 kg/m2, P = 0.022). Similarly, patients requiring IMV had a higher BMI (33 vs. 29, P = 0.002) compared to non-intubated patients. The unadjusted OR for patients with a higher BMI requiring IMV (56% vs. 28%, OR: 3.3, 95% CI: 1.6 - 7.0, P = 0.002) and upgrade to ICU (46% vs. 28%, OR; 2.2, 1.07 - 4.6, P = 0.04) were significantly higher compared to patients with a lower BMI. Similarly, patients with a higher BMI had higher in-hospital mortality (21% vs. 9%, OR: 3.2, 95% CI: 1.3 - 8.2, P = 0.01) compared to patients with a normal BMI. Despite a numerical advantage in the lower BMI group, there was no significant difference between the two groups in terms of the need for dialysis (5% vs. 13%, OR: 3.8, 13% vs. 4%, 1.1 - 14.1, P = 0.07). aORs controlled for baseline comorbidities and medications mirrored the overall results, except for the need to upgrade to ICU. CONCLUSIONS: In patients with confirmed COVID-19, morbid obesity serves as an independent risk factor of high in-hospital mortality and the need for IMV.

Predictability of CRP and D-Dimer levels for in-hospital outcomes and mortality of COVID-19.

BACKGROUND: Systemic inflammation elicited by a cytokine storm is considered a hallmark of coronavirus disease 2019 (COVID-19). This study aims to assess the clinical utility of the C-reactive protein (CRP) and D-Dimer levels for predicting in-hospital outcomes in COVID-19. METHODS: A retrospective cohort study was performed to determine the association of CRP and D-Dimer with the need for invasive mechanical ventilation (IMV), dialysis, upgrade to an intensive care unit (ICU) and mortality. Independent t-test and multivariate logistic regression analysis were performed to calculate mean differences and adjusted odds ratios (aOR) with its 95% confidence interval (CI), respectively. RESULTS: A total of 176 patients with confirmed COVID-19 diagnosis were included. On presentation, the unadjusted odds for the need of IMV (OR 2.5, 95% CI 1.3-4.8, p = 0.012) and upgrade to ICU (OR 3.2, 95% CI 1.6-6.5, p = 0.002) were significantly higher for patients with CRP (>101 mg/dl). Similarly, the unadjusted odds of in-hospital mortality were significantly higher in patients with high CRP (>101 mg/dl) and high D-Dimer (>501 ng/ml), compared to corresponding low CRP (<100 mg/dl) and low D-Dimer (<500 ng/ml) groups on day-7 (OR 3.5, 95% CI 1.2-10.5, p = 0.03 and OR 10.0, 95% CI 1.2-77.9, p = 0.02), respectively. Both high D-Dimer (>501 ng/ml) and high CRP (>101 mg/dl) were associated with increased need for upgrade to the ICU and higher requirement for IMV on day-7 of hospitalization. A multivariate regression model mirrored the overall unadjusted trends except that adjusted odds for IMV were high in the high CRP group on day 7 (aOR 2.5, 95% CI 1.05-6.0, p = 0.04). CONCLUSION: CRP value greater than 100 mg/dL and D-dimer levels higher than 500 ng/ml during hospitalization might predict higher odds of in-hospital mortality. Higher levels at presentation might indicate impending clinical deterioration and the need for IMV.

Lymphocyte-to-C-Reactive Protein Ratio: A Novel Predictor of Adverse Outcomes in COVID-19.

BACKGROUND: Systemic inflammation elicited by a cytokine storm is considered a hallmark of coronavirus disease 2019 (COVID-19). This study aims to assess the validity and clinical utility of the lymphocyte-to-C-reactive protein (CRP) ratio (LCR), typically used for gastric carcinoma prognostication, versus the neutrophil-to-lymphocyte ratio (NLR) for predicting in-hospital outcomes in COVID-19. METHODS: A retrospective cohort study was performed to determine the association of LCR and NLR with the need for invasive mechanical ventilation (IMV), dialysis, upgrade to an intensive care unit (ICU) and mortality. Independent t-test and multivariate logistic regression analysis were performed to calculate mean differences and adjusted odds ratios (aORs) with its 95% confidence interval (CI), respectively. RESULTS: The mean age for NLR patients was 63.6 versus 61.6, and for LCR groups, it was 62.6 versus 63.7 years, respectively. The baseline comorbidities across all groups were comparable except that the higher LCR group had female predominance. The mean NLR was significantly higher for patients who died during hospitalization (19 vs. 7, P ≤ 0.001) and those requiring IMV (12 vs. 7, P = 0.01). Compared to alive patients, a significantly lower mean LCR was observed in patients who did not survive hospitalization (1,011 vs. 632, P = 0.04). For patients with a higher NLR (> 10), the unadjusted odds of mortality (odds ratios (ORs) 11.0, 3.6 - 33.0, P < 0.0001) and need for IMV (OR 3.3, 95% CI 1.4 - 7.7, P = 0.008) were significantly higher compared to patients with lower NLR. By contrast, for patients with lower LCR (< 100), the odds of in-hospital all-cause mortality were significantly higher compared to patients with a higher LCR (OR 0.2, 0.06 - 0.47, P = 0.001). The aORs controlled for baseline comorbidities and medications mirrored the overall results, indicating a genuinely significant correlation between these biomarkers and outcomes. CONCLUSIONS: A high NLR and decreased LCR value predict higher odds of in-hospital mortality. A high LCR at presentation might indicate impending clinical deterioration and the need for IMV.

Dapagliflozin-induced Late-onset Euglycemic Diabetic Ketoacidosis.

Sodium-glucose co-transporter-2 (SGLT2) inhibitors are a class of oral hypoglycemics that improve glycemic control by increasing the urinary excretion of glucose. They gained widespread popularity because they not only showed improved glycemic control but also had a favorable effect on weight loss, blood pressure, and cardiovascular mortality. One of their rare side effects is euglycemic diabetic ketoacidosis (eDKA) although the diagnosis is sometimes difficult to make due to near-normal glucose levels. We present a case of eDKA in a patient who presented with confusion, acute kidney injury (AKI), and metabolic acidosis after having an influenza-like illness with a minimally elevated blood glucose of 187 mg/dL. She had already stopped taking dapagliflozin (an SGLT-2 inhibitor) two weeks before the presentation. She was initially treated as sepsis and required hemodialysis. Later on, metabolic acidosis was attributed to eDKA from dapagliflozin, which resolved after the administration of intravenous insulin. Her eDKA developed while she had already stopped dapagliflozin two weeks ago, which makes this an interesting case finding. It is one of those rare cases where dapagliflozin led to a delayed complication of eDKA.

Prevalence of hypertension in healthy school children in Pakistan and its relationship with body mass index, proteinuria and hematuria.

To determine the prevalence of high blood pressure (BP) in healthy school Pakistani children and its association with high body mass index (BMI), asymptomatic hematuria and proteinuria, we studied 661 public school children and measured their body weight, height and BP and urine dipstick for hematuria performed on a single occasion. Hypertension (BP >95 th centile) and pre-hypertension (BP >90 th centile) were defined based on the US normative BP tables. Over-weight and obesity were defined according to the World Health Organization (WHO) classification of BMI. The mean age of the children was 14 ± 1.3 years. The mean BMI was 18.5 ± 4.3 kg/m 2 . The majority (81.8%) of the children were found to be normotensive (BP <90 th centile). Pre-hypertension was observed in 15% and hypertension in 3% of the children. Overweight was observed in 7.7% and obesity in 1% of the children. The independent risk factors for hypertension and pre-hypertension were age of the child (RR 1.2 95% CI 1-1.4), gender (RR 2.0 for being female 95% CI 1-4.4), BMI >25 (RR for BMI b/w 25-30 = 2.6, RR for BMI >30 = 4.3), positive urine dipstick for proteinuria (RR = 2.3 95% CI 0.7-7.7) and positive urine dipstick for hematuria (RR 1.0 95% CI 0.2-8.3). Hypertension in children is strongly correlated with obesity, asymptomatic proteinuria and hematuria. Community based screening programs for children should include BP recording, BMI assessment and urine dipsticks analysis and approach high-risk groups for early detection and lifestyle modifications.
