Blood Glucose and Sodium Level as Potential Indicators for Hospital Mortality among Patients with Acute Stroke in a Tertiary Hospital, India

ABSTRACT During acute stroke, blood glucose and sodium may fluctuate and act as a predictor for mortality. The purpose of the study was to predict potential indicators of in-hospital mortality, based on blood sugar and sodium. There were 60 participants, of which 30 were allotted to random blood glucose and 30 to blood sodium group. On admission demographic, clinical variables, RAAC scale, and mini-mental status examination were assessed. The RBS and blood sodium was assessed on admission and 10th day of admission for group A and group B, respectively. Both groups showed improvement in RBS/sodium towards normal on the 10th day of admission. No mortality in either group. Hospitalization days were more in group B.

Changes in Interprofessional Practice During the COVID-19 Pandemic and the Effect on Patient Outcomes: A Retrospective Observational Study.

Changes in healthcare delivery were required during the first year of the COVID-19 pandemic. The purpose of this study was to determine the impact of the approach to care of the COVID-19 patient on nursing sensitive indicators and nutrition therapy and the utilization of rehabilitation services during the first year of the pandemic in the acute care setting. A retrospective study of 894 patients admitted with a COVID-19 diagnosis was conducted between March 2020 and February 2021 in 3-month cohorts. All charts were reviewed for general demographics and hospital data, nursing quality indicators, and nutritional and rehabilitation services for the first 30 days of admission. Differences in patient characteristics were noted among the cohorts. Variations were observed between time points in hospital-acquired pressure injury occurrence, with mechanical ventilation and proning being independent predictors of hospital-acquired pressure injuries. There were differences noted in the percentage of patients with a central line-associated bloodstream infection among the time points (P < .001), but there were no differences noted in catheter-associated urinary tract infections (P = .20). Overall, 15.5% had a malnutrition diagnosis, with most patients receiving 50% of prescribed calorie and protein needs. Rehabilitation services increased over time with these services being initiated earlier in the later cohorts (P < .001). The results of this study demonstrated the impact of the pandemic on outcomes in the areas of nursing, nutrition, and rehabilitation, which varied across quarterly cohorts as we learned and developed new practices and adapted to a novel pandemic.

A Machine Learning Exploration of Social Determinants of Health and Hospital-Onset Bacteremia, Northern California, 2019–2023

Introduction: Social determinants of health can impact healthcare-associated infections. Hospital-onset bacteremia (HOB) may lead to poor outcomes, increased length of stay, and increased cost of care. We explored the association of social determinants of health and HOB. Methods: We retrieved blood culture data at Stanford Health Care from May 2019 to October 2023. We identified blood cultures ordered ≥4 days of admission. To evaluate the association between social determinants of health and HOB, we employed an unsupervised machine learning approach (K-Means clustering) to discern patterns in HOB rates based on the Social Vulnerability Index (SVI). The SVI indicates the relative vulnerability of every U.S. Census tract. It ranks the tracts on 16 measures of vulnerability across 4 themes: socioeconomic factors, household characteristics, racial and ethnic minority status, and housing/transportation aspects. The number of clusters was determined using the Elbow Method (Figure 1). Results: Out of 209,947 blood cultures from 23,938 unique patients with a California address, we identified 81,653 blood cultures collected after 4 days (40%). The K-Means clustering algorithm identified 3 distinct clusters within the Californian census tracts, suggesting heterogeneity in the relationship between SVI and HOB (Figure 2). Cluster 1 had a higher SVI (median 0.73, range 0.46 – 0.99), with logistic regression indicating a positive SVI-HOB association (OR 4.84, 95% CI 4.02 – 4.81, p &lt;.001). Cluster 2, had a median SVI of 0.29 (range 0.0009 – 0.78), also showed a positive association between SVI and HOB (OR 1.67, 95% CI 1.4 – 1.89, p &lt;.001), aligning with trends of higher infection risks in more vulnerable groups. In contrast, Cluster 3 had a median SVI of 0.22 (range 0.002 –0.84). In this cluster, the SVI showed a negative association with HOB (OR 0.24, 95% CI 0.18 – 0.31, p &lt;.001). Cluster 3 was the cluster with the least number of subjects (15,000, versus 21,761 for Cluster 1 and 29,762 for Cluster 2). Most subjects in Cluster 3 resided in Santa Clara County, whereas those in Clusters 1 and 2 were spread across Santa Clara, San Mateo, Alameda, Merced, and Sacramento Counties (Figure 3). Conclusions: Advanced techniques can be used to explore the complex interplay between social determinants of health and healthcare-associated infections and could guide the development of community-specific strategies to improve outcomes.

Toxic Epidermal Necrolysis by Lamotrigine - A Case Report of Fatality

Toxic epidermal necrolysis (TEN) is an immune mediated fatal adverse muco-cutaneous drug reaction characterized by extensive exfoliation of the epidermis and mucous membrane. It may result in sepsis and death. In most cases, TEN is caused by certain drugs &amp; vaccines. TEN involves more than 30% of body surface area. Steven Johnson Syndrome also shows the same disease process and same spectrum of drug-induced epidermolysis. A 37-year-old patient who was on Lamotrigine, Escitalopram &amp; Clonazepam for multiple somatoform disorder developed generalized vesicular rash with fever after 2 weeks of initiation of lamotrigine. The patient was admitted to the hospital and Lamotrigine was taken off. Patient was given conservative management. Adverse drug reaction was reported to Adverse drug reaction monitoring centre (AMC) and severity was assessed by WHO-UMC Scale. Patient died after 5 days of admission. Score of Toxic epidermal necrolysis (SCORTEN Scale) is used to assess severity of the illness and to predict mortality rate. Early Diagnosis, withdrawal of offending agent, timely proper supportive management can help in lowering the mortality.

Study on the procoagulant characteristics of microparticles in acute myocardial infarction

To investigate the characteristic of circulating microparticle in patients with acute myocardial infarction (AMI) and its possible mechanism of promoting coagulation. A prospective case-control study was conducted. The patients with coronary heart disease admitted to the second department of cardiology in Harbin First Hospital from June to November 2023 were enrolled, and they were grouped according to whether the patients occurred AMI or not. On the day of admission, disseminated intravascular coagulation (DIC) score was calculated. At the same time, fasting venous blood was collected, and the levels of D-dimer, fibrin degradation product (FDP) and the activities of major coagulation factors were detected. The level of circulating microparticle was determined by microparticle trapping method. The microparticle carrying tissue factor (TF+MP) level was detected by tissue factor (TF) dependent F Xa production assay. Spearman correlation method was used to analyze the correlation among the indicators. A total of 52 patients with coronary heart disease were enrolled, including 26 patients in AMI group and 26 patients in non-AMI group. There was no significant difference in gender, age, body mass index (BMI), underlying diseases, smoking history, and pre-admission treatment of patients between the two groups, indicating that the baseline data of the two groups were balanced and comparable. Compared with the non-AMI group, the DIC score and D-dimer, FDP levels in the AMI group were significantly increased [DIC score: 3 (3, 4) vs. 3 (2, 3), D-dimer (mg/L): 8.80 (6.84, 15.66) vs. 2.13 (1.64, 3.86), FDP (mg/L): 30.13 (19.30, 52.54) vs. 20.00 (13.51, 28.37), all P < 0.01], indicating that the degree of coagulation activation in AMI patients was more severe. The consumption of major coagulation factors in the coagulation pathway in the AMI group was heavier than that in the non-AMI group [F II: 59.45% (49.65%, 71.25%) vs. 63.65% (49.98%, 73.22%), F V: 96.95% (73.50%, 112.78%) vs. 105.05% (73.48%, 131.48%), F VII: 42.30% (36.98%, 51.98%) vs. 53.40% (46.58%, 69.88%), F X: 60.90% (48.22%, 80.82%) vs. 73.50% (56.80%, 85.98%), F XI: 82.45% (62.90%, 99.10%) vs. 92.40% (73.90%, 114.25%), F XII: 29.90% (12.42%, 42.38%) vs. 34.65% (16.32%, 48.20%), all P < 0.05]. The circulating TF+MP level in the AMI group was significantly higher than that in the non-AMI group [nmol/L: 0.13 (0.06, 0.20) vs. 0.08 (0.04, 0.15), P < 0.05]. There was no significant difference in the level of circulating microparticle between AMI group and non-AMI group [nmol/L: 1.24 (0.71, 3.77) vs. 1.35 (0.73, 2.14), P > 0.05]. Correlation analysis showed that circulating TF+MP level in the patients with coronary heart disease was significantly positively correlated with coagulation indicator DIC score (r = 0.307, P = 0.027), D-dimer (r = 0.696, P < 0.001) and FDP (r = 0.582, P < 0.001), and there was a strong negative correlation with exogenous pathway factor F VII (r = -0.521, P < 0.001) and common pathway factor F X (r = -0.332, P = 0.016). The circulating TF+MP level in AMI patients was significantly higher than that in the non-AMI patients. TF+MP may play an important role in activating the extrinsic coagulation pathway, exacerbating coagulation factor consumption, and promoting clot formation during AMI occurrence.

The predictive value of GLIM criteria on clinical outcomes and responses to nutritional support in patients with neurocritical illnesses

Neurocritically ill patients frequently exhibit coma, gastroparesis, and intense catabolism, leading to an increased risk of malnutrition. The Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition was created to achieve a consistent malnutrition diagnosis across diverse populations. This study aimed to validate the concurrent and predictive validity of GLIM criteria in patients with neurocritical illnesses. A total of 135 participants were followed from admission to the neurocritical unit (NCU) until discharge. Comparing GLIM criteria to the Subjective Global Assessment (SGA), sensitivity was 0.95 and specificity was 0.69. Predictive validity of GLIM criteria was assessed using a composite adverse clinical outcome, comprising mortality and various major complications. Adjusted hazard ratios for moderate and severe malnutrition were 2.86 (95% CI 1.45–5.67) and 3.88 (95% CI 1.51–9.94), respectively. Changes in indicators of nutritional status, including skeletal muscle mass and abdominal fat mass, within 7 days of admission were obtained for 61 participants to validate the predictive capability of the GLIM criteria for the patients’ response of standardized nutritional support. The GLIM criteria have a statistically significant predictive validity on changes in rectus femoris muscle thickness and midarm muscle circumference. In conclusion, the GLIM criteria demonstrate high sensitivity for diagnosing malnutrition in neurocritically ill patients and exhibit good predictive validity.

The Usefulness of Strain Echocardiography as Diagnostic and Prognostic Index of Cardiac Dysfunction in Septic Patients in Correlation with Cardiac Biomarkers.

Compared to standard echocardiography, speckle tracking echocardiography (STE) looks more accurate for the detection of subclinical dysfunction of the myocardium. The aim of our work was to assess the value of STE in the diagnosis of subclinical ventricular dysfunction and as a prognostic index in sepsis patients. An observational prospective study involving critically ill patients aged ≥ 18 years diagnosed with sepsis or septic shock. All patients were subjected to full history-taking, clinical assessment, and scoring system, including Acute Physiology and Chronic Health (APACHE) II score and quick sequential organ failure assessment score. Investigations were done for all patients, including laboratory (complete blood count, C-reactive protein, N-terminal pro-brain natriuretic peptide [NT-proBNP], and troponin-I and serum lactate level), ECG, and echocardiographic examination (conventional and speckle tracking) for measurement of global left ventricular strain. This study involved 50 patients, nine patients with sepsis and 41 patients with septic shock. Regarding cardiac biomarkers, the mean value of troponin-I was 0.18 ± 0.05 ng/L and for NT-proBNP was 1228.2 ± 832.9 pmol/L. All patients in the study had elevated lactate levels. There was a significant correlation between global longitudinal strain (GLS) and troponin I, NT-proBNP, and lactate levels after 3 days of admission. GLS, lactate, NT-proBNP, troponin levels, and APACHE II Score were significant predictors of mortality with a sensitivity of 76.5%, 88.2%, 88.2%, 76.5%, and 88.2%, respectively. GLS measured by speckle tracking echocardiography looks to be a sensitive diagnostic tool for early detection of subclinical left ventricular dysfunction in patients with sepsis in addition to be a sensitive predictor of in-hospital mortality.

RENIN AND ANGIOTENSIN (1-7) OFFER PREDICTIVE VALUE IN PEDIATRIC SEPSIS: FINDINGS FROM PROSPECTIVE OBSERVATIONAL COHORTS.

Background: Pediatric sepsis is a common and complex syndrome characterized by a dysregulated immune response to infection. Aberrations in the renin-angiotensin system (RAS) are factors in several infections of adults. However, the precise impact of RAS dysregulation in pediatric sepsis remains unclear. Methods: Serum samples were collected from a derivation cohort (58 patients with sepsis, 14 critically ill control subjects, and 37 healthy controls) and validation cohort (50 patients with sepsis, 37 critically ill control subjects, and 46 healthy controls). Serum RAS levels on day of pediatric intensive care unit admission were determined and compared with survival status and organ dysfunction. Results: In the derivation cohort, the serum renin concentration was significantly higher in patients with sepsis (3,678 ± 4,746) than that in healthy controls (635.6 ± 199.8) ( P < 0.0001). Meanwhile, the serum angiotensin (1-7) was significantly lower in patients with sepsis (89.7 ± 59.7) compared to that in healthy controls (131.4 ± 66.4) ( P < 0.01). These trends were confirmed in a validation cohort. Nonsurvivors had higher levels of renin (8,207 ± 7,903) compared to survivors (2,433 ± 3,193) ( P = 0.0001) and lower levels of angiotensin (1-7) (60.9 ± 51.1) compared to survivors (104.0 ± 85.1) ( P < 0.05). A combination of renin, angiotensin (1-7) and procalcitonin achieved a model for diagnosis with an area under the receiver operating curve of 0.87 (95% CI: 0.81-0.92). Conclusion: Circulating renin and angiotensin (1-7) have predictive value in pediatric sepsis.

Observations on the Clinical Effects of Music Therapy on Premature Infants in Neonatal Intensive Care Units.

This study aimed to explore the clinical effects of music therapy (MT) on premature infants in neonatal intensive care units (NICUs). A total of 78 premature infants in NICUs admitted from January 2021 to January 2022 in Wuhan Children's Hospital, Tongji Medical College, and Huazhong University of Science and Technology were selected as the reference group and received routine management. Wuhan Children's Hospital implemented MT from February 2022 to February 2023, and 74 premature infants in NICUs admitted during the same period were selected as the observation group. The corresponding management mode was implemented on the second day of NICU admission for premature infants. Amplitude-integrated electroencephalogram (aEEG) and neonatal behavioral neurological assessment (NBNA) were adopted to evaluate the brain function, specifically the neurological function of neonates, after the end of management. The degree of parent-child attachment was measured using the pictorial representation of attachment measure (PRAM) in a nonverbal (visual) manner. The temperature, pulse, respiratory rate (RR), the number and duration of crying, and incidence of complications were all compared between the two groups. SPSS showed that no difference existed in the aEEG and NBNA scores between the two groups (P > 0.05). The distance of PRAM self-baby-distance was smaller in the observation group compared with the reference group (P < 0.05). Furthermore, there was no significant difference in temperature between the two groups (P > 0.05). The observation group had significantly lower pulse and RR values than the reference group (P < 0.05). Finally, no significant difference existed in the incidence of complications between the two groups (P > 0.05). MT has a certain application value for premature infants in NICUs and can thus be applied to newborns in other NICUs. However, further studies are required to completely verify the research results.

Guideline-unjustified inpatient therapy for non-ICU patients with community-acquired pneumonia (CAP) at 105 Veterans Affairs

Background: CAP is often inappropriately treated with agents active against multidrug-resistant organisms (MDRO; methicillin-resistant S. aureus [MRSA] and P. aeruginosa [PSA]) and for prolonged duration. We assessed the relationship between antibiotic use with ATS/IDSA guideline-unjustified empiric and definitive MDRO therapy and prolonged duration in non-ICU inpatients with CAP at 105 VA Medical Centers. Methods: From VA Corporate Data Warehouse data, we identified patients with discharge ICD-10-CM codes consistent with CAP from 1/2022-3/2023, excluding cases with 14 days of antibiotic therapy, ICU admission, concurrent infections, or severe immunocompromise. We considered as jultified empiric (≤third day of hospitalization) therapy: anti-MRSA therapy for patients with prior positive MRSA cultures, anti-PSA therapy for patients with prior positive PSA cultures, and both anti-MRSA &amp; anti-PSA therapy in patients with severe pneumonia and intravenous antibiotics in the prior 3 months. Definitive (&gt;third day of hospitalization) anti-MDRO therapy was considered unjustified in patients who had achieved clinical stability and whose cultures did not grow MRSA or PSA. Prolonged duration (&gt;6 days of therapy) was unjustified if patients were clinically stable or discharged by day 5. Results: The median age of the 29,260 patients was 75 (IQR 69,81); 4.6% were women. While 33% and 22% of patients received empiric or definitive MDRO therapy, such therapy was jultified in 12% and 0.5%, respectively. Median facility use of empiric and definitive MDRO therapy was 31% (IQR 25%,38%) and 20% (15%,23%), respectively (Figure 1); this use was unjustified in 89% (85%,93%) and 100% (100%,100%), respectively. Pearson’s correlation coefficient between MDRO therapy and rates of unjustified empiric and definitive MDRO therapy for CAP was 0.54 and 0.61, respectively (Figure 2). Although 99% of patients were discharged or stable by day 5, 42% received prolonged therapy. The median frequency of prolonged therapy was 39% (33%,48%); facility rates of prolonged therapy had a correlation of 0.56 with total antibiotic use and 0.46 with MDRO therapy (Figure 3). Discussion: Based on electronic documentation, we identified 1) substantial opportunities to reduce unjustified anti-MDRO therapy and the duration of therapy in hospitalized non-ICU patients with CAP; 2) a moderate correlation of unjustified anti-MDRO therapy with increased MDRO antibiotic use and of prolonged duration of therapy with increased total and MDRO antibiotic use. The correlation of lower quality prescribing with increased antibiotic use provides further impetus for tools such as dashboards (Figure 4) to assist antibiotic stewards in designing and monitoring interventions to reduce unjustified therapy.

Urgent Thoracic Endovascular Aortic Repair for Type-B0,D Acute Aortic Dissection

The objective of the present study is to clarify safety and efficacy of thoracic endovascular aortic repair (TEVAR), excluding the primary entry in the descending aorta, for type-B0,D acute aortic dissection (TB0,DAAD) (so-called retrograde type-A acute aortic dissection). Forty-six patients with hyperacute-phase (within 2days after the onset) type-A acute aortic dissection (TAAAD) and TB0,DAAD underwent urgent (on the admission or next day) intervention (TEVAR or conventional surgical aortic repair [CSAR]) for 2years. Results of TEVAR for TB0,DAAD were compared with those of CSAR for TAAAD. Outcomes included 30-day mortality, aortic reintervention, and major complications (stroke and paraplegia/paraparesis). Details of TEVAR were also analyzed. Seven patients with TB0,DAAD and 39 patients with TAAAD underwent respectively urgent TEVAR and CSAR. Aortic reintervention was significantly more frequent in the TEVAR than CSAR group (28.6% vs. 0%, P<0.01). There was no difference in incidence of death and stroke between the TEVAR and CSAR group. All the 7 patients survived and 5 of the 7 (71.4%) patients were relieved of aortic reintervention for 30days following TEVAR. One patient, however, underwent aortic arch replacement on postoperative day (POD) 1 owing to the patent and nonshrinking ascending false lumen (FL). The entry existed in the aortic arch. Another patient underwent ascending and transverse aortic replacement with frozen elephant trunk on POD13 due to proximal stent graft-induced new entry irrespective of the thrombosed and shrinking ascending FL. Because of the patent and nonshrinking ascending FL, 1 patient underwent additional TEVAR for the residual entry in the distal descending thoracic aorta on POD33 and subsequently ascending aortic replacement 4months later. No entry was detected in the ascending or transverse aorta. The ascending FL in the other 4 patients was thrombosed early, shrinking gradually, and disappeared at last following TEVAR. Urgent TEVAR for TB0,DAAD may be alternative to CSAR in selected cases. Accurate diagnosis of the primary entry location on preinterventional computed tomography scans for exclusion of the entry and cautious selection and delivery of a stent graft to prevent stent graft-induced new entry or endoleak are requisite for success of the procedure, remodeling of the FL, and satisfactory prognosis.

Serum Albumin as a Marker of Metabolic Response to Injury and its Role with Calorie Intake Regarding Length of Stay, Readmission Rates and Hospital Survival

Background: Studies have shown a relationship between albumin level &amp; hospital mortality, but none have looked at low serum albumin, calorie intake and survival. Aim: To evaluate the relationship between serum albumin level, calorie intake, length of hospital stay (LOS), readmission rates and hospital mortality in a large population of disadvantaged and underinsured patients at a County of Los Angeles Medical Center. Design: Prospective observational study using data collected over a 6-year period of hospital survival, LOS and readmission rate in 11,441 patients. Calorie intake in those 400 patients with serum albumin &lt;1.5 g/dL was collected. Our hypothesis was to test if the relationship of admission serum albumin to mortality was linear or exponential. In addition, in those with a serum albumin &lt;1.5 g/dL, we evaluated calorie intake and hospital survival. Methods: A total of 11,441 patients were included in the dataset. ANOVA and regression analysis were performed. Calorie intake was extracted from dietary and intravenous intake data of each of the 400 patients with an albumin &lt;1.5 g/dL. Results: Serum albumin was obtained within the first 7 days of admission in all patients. Mortality increased in patients with admission serum albumin &lt;3.5 g/dL (8.8% vs 2.3%, p&lt;0.05). Serum albumin was exponentially related to mortality (mortality = 32 / albumin2; p &lt;0.01). The group of patients with albumin &lt;1.5 g/dL had the greatest mortality rate (18%), approximately seven times that of patients with normal serum albumin levels. These patients also had an average LOS of 14.7 days (p&lt;0.05), twice that of patients with normal albumin values. 30-day admission rates for this group were three times greater (6.3% vs. 1.9%, p&lt;0.05). Calorie intake was associated with a dose response curve with regards to hospital mortality. Conclusion: A single measurement of serum albumin identifies patients who are at high risk for prolonged hospital stay, readmission and mortality. Calorie intake may modify mortality risk, but prospective studies are needed.

Novaluron and indoxacarb induced methemoglobinemia – unveiling a rare poisoning

Introduction and aim. In India, the utilization of agricultural pesticides for intentional self-poisoning is a prevalent method, and it is associated with substantially higher fatality rates compared to other self-poisoning approaches. Plethora, an agricultural insecticide containing novaluron (5.25%) and indoxacarb (4.5%), has recently been introduced and widely used in India and various other regions for its broad-spectrum lepidopteran control. While there have been documented cases of isolated self-poisoning involving indoxacarb, there is currently no literature reporting incidents of human poisoning specifically related to novaluron. Description of the case. An 83-Year-old male was presented to the emergency department (ED) with a history of consumption of 50 mL of an insecticide suspension concentrate called ‘PLETHORA’ to commit suicide. He had one episode of vomiting and dizziness after the ingestion. There was associated cyanosis, and the patient was put on high-flow oxygen at 10 L/min through a face mask. The patient was diagnosed to have methemoglobinemia and was successfully treated with methylene blue and ascorbic acid. One hour post methylene blue injection showed a methemoglobin level of 1%, and the patient gradually improved. Patients presenting with novaluron and indoxacarb poisoning require supportive treatment as there is no specific antidote. There should be a high index of suspicion for methemoglobinemia in such patients, and timely management is necessary to prevent further complications. The patient was successfully managed and discharged after the 3rd day of admission. Conclusion. The management of patients with novaluron and indoxacarb poisoning primarily involves supportive care, as there is currently no specific antidote available for these substances. Maintaining a high suspicion index for the development of methemoglobinemia and timely management of other complications is crucial for the best possible patient outcomes.

Complex Patterns of Antihypertensive Treatment Changes in Long-Term Care Residents

ObjectivesAntihypertensive treatment changes are common in long-term care residents, yet data on the frequency and predictors of changes are lacking. We described the patterns of antihypertensive changes and examined the triggering factors. DesignRetrospective cohort study. Setting and ParticipantsA total of 24,870 Department of Veterans Affairs (VA) nursing home residents aged ≥65 years with long-term stays (≥180 days) from 2006 to 2019. MethodsWe obtained data from the VA Corporate Data Warehouse. Based on Bar Code Medication Administration medication data, we defined 2 types of change events in 180 days of admission: deprescribing (reduced number of antihypertensives or dose reduction of ≥30% compared with the previous week and maintained for at least 2 weeks) and intensification (opposite of deprescribing). Mortality was identified within 2 years after admission. ResultsMore than 85% of residents were prescribed antihypertensives and 68% of them experienced ≥1 change event during the first 6 months of the nursing home stay. We categorized residents into 10 distinct patterns: no change (27%), 1 deprescribing (11%), multiple deprescribing (5%), 1 intensification (10%), multiple intensification (7%), 1 deprescribing followed by 1 intensification (3%), 1 intensification followed by 1 deprescribing (4%), 3 changes with mixed events (7%), >3 changes with mixed events (10%), and no antihypertensive use (15%). Treatment changes were more frequent in residents with better physical function and/or cognitive function. Potentially triggering factors differed by the type of antihypertensive change: incident high blood pressure and cardiovascular events were associated with intensification, and low blood pressure, weight loss, and falls were associated with deprescribing. Death occurred in 7881 (32%) residents over 2 years. The highest mortality was for those without antihypertensive medication (incidence = 344/1000 person-years). Conclusions and ImplicationsPatterns of medication changes existing in long-term care residents are complex. Future studies should explore the benefits and harms of these antihypertensive treatment changes.

Effectiveness of dolutegravir in moderate severity COVID-19 patients: A single-center, randomized, double-blind, placebo-controlled trial

Introduction: Drug repurposing as a low-cost, time-saving, and often less risky strategy has been attractive for the treatment of coronavirus disease 2019 (COVID-19) during the pandemic. This trial aimed to evaluate the effectiveness of dolutegravir, an HIV-1 integrase inhibitor, in admitted patients with moderate COVID-19. Methods: This study was a randomized, double-blind, placebo-controlled clinical trial assessing the efficacy of dolutegravir in adults admitted to a hospital in Ghaemshahr, Mazandaran Province, Iran. Patients aged 18-80 years with early symptoms of moderate COVID-19, which was confirmed based on reverse transcription polymerase chain reaction (RT-PCR) and/or chest computed tomography (CT) scan, were considered to be included in this study. Patients were randomly assigned in a 1:1 ratio to receive 50 mg dolutegravir plus the standard treatment regimen or the same value of placebo plus the standard treatment regimen, daily for 7 days. The standard treatment regimen was remdesivir 200 mg on day 1 followed by 100 mg for five days or until discharge. The primary endpoint was recovery 10 days after the beginning of the study. Results: Between August 22 and October 23, 2021, of 120 patients who were enrolled, 93 patients were randomly assigned to receive 50 mg dolutegravir (n = 46) or the placebo regimen (n = 47). No significant difference was observed between the two intervention groups based on the obtained results including frequency of respiratory modes during the first five days of admission, respiratory rate, and O2 saturation during six time periods. Conclusion: The results showed that in adult patients admitted to the hospital with moderate COVID-19, treatment with dolutegravir was not associated with improvement in clinical recovery. Larger randomized trials are required to provide more robust evidence about the effectiveness of dolutegravir.

Pneumonia Risk, Antipsychotic Dosing, and Anticholinergic Burden in Schizophrenia

Antipsychotic drugs (particularly clozapine) have been associated with pneumonia in observational studies. Despite studies of the associations between antipsychotic use and incident pneumonia, it remains unclear to what degree antipsychotic use is associated with increased risk of pneumonia, whether dose-response associations exist, and what agents are specifically associated with incident pneumonia. To estimate pneumonia risk associated with specific antipsychotics and examine whether polytherapy, dosing, and receptor binding properties are associated with pneumonia in patients with schizophrenia. This cohort study identified patients with schizophrenia or schizoaffective disorder (hereafter, schizophrenia) aged 16 years or older from nationwide Finnish registers from 1972 to 2014. Data on diagnoses, inpatient care, and specialized outpatient care were obtained from the Hospital Discharge Register. Information on outpatient medication dispensing was obtained from the Prescription Register. Study follow-up was from 1996 to 2017. Data were analyzed from November 4, 2022, to December 5, 2023. Use of specific antipsychotic monotherapies; antipsychotics modeled by dosage as low (<0.6 of the World Health Organization defined daily dose [DDD] per day), medium (0.6 to <1.1 DDDs per day), or high dose (≥1.1 DDDs per day); antipsychotic polypharmacy; and antipsychotics categorized according to their anticholinergic burden as low, medium, and high. The primary outcome was hospitalization for incident pneumonia. Pneumonia risk was analyzed using adjusted, within-individual Cox proportional hazards regression models, with no antipsychotic use as the reference. The study included 61 889 persons with schizophrenia (mean [SD] age, 46.2 [16.0] years; 31 104 men [50.3%]). During 22 years of follow-up, 8917 patients (14.4%) had 1 or more hospitalizations for pneumonia and 1137 (12.8%) died within 30 days of admission. Compared with no antipsychotic use, any antipsychotic use overall was not associated with pneumonia (adjusted hazard ratio [AHR], 1.12; 95% CI, 0.99-1.26). Monotherapy use was associated with increased pneumonia risk compared with no antipsychotic use (AHR, 1.15 [95% CI, 1.02-1.30]; P = .03) in a dose-dependent manner, but polytherapy use was not. When categorized by anticholinergic burden, only the use of antipsychotics with a high anticholinergic burden was associated with pneumonia (AHR, 1.26 [95% CI, 1.10-1.45]; P < .001). Of specific drugs, high-dose quetiapine (AHR, 1.78 [95% CI, 1.22-2.60]; P = .003), high- and medium-dose clozapine (AHR, 1.44 [95% CI, 1.22-1.71]; P < .001 and AHR, 1.43 [95% CI, 1.18-1.74]; P < .001, respectively), and high-dose olanzapine (AHR, 1.29 [95% CI, 1.05-1.58]; P = .02) were associated with increased pneumonia risk. Results of this cohort study suggest that in patients with schizophrenia, antipsychotic agents associated with pneumonia include not only clozapine (at dosages ≥180 mg/d) but also quetiapine (≥440 mg/d) and olanzapine (≥11 mg/d). Moreover, monotherapy antipsychotics and antipsychotics with high anticholinergic burden are associated with increased pneumonia risk in a dose-dependent manner. These findings call for prevention strategies aimed at patients with schizophrenia requiring high-risk antipsychotics.

Association between hyperglycemia at ICU admission and postoperative acute kidney injury in patients undergoing cardiac surgery: Analysis of the MIMIC-IV database

BackgroundThis study aimed to explore the correlation between hyperglycemia at intensive care unit (ICU) admission and the incidence of acute kidney injury (AKI) in patients after cardiac surgery. MethodsWe conducted a retrospective cohort study, in which clinical data were extracted from the Medical Information Mart for Intensive Care (MIMIC)-IV database. Adults (≥18 years) in the database who were admitted to the cardiovascular intensive care unit after cardiac surgery were enrolled. The primary outcome was the incidence of AKI within 7 days following ICU admission. Secondary outcomes included ICU mortality, hospital mortality, ICU length of stay, and the 28-day and 90-day mortality. Multivariable Cox regression analysis was used to assess the association between ICU-admission hyperglycemia and AKI incidence within 7 days of ICU admission. Different adjustment strategies were used to adjust for potential confounders. Patients were divided into three groups according to their highest blood glucose levels recorded within 24 h of ICU admission: no hyperglycemia (<140 mg/dL), mild hyperglycemia (140–200 mg/dL), and severe hyperglycemia (≥200 mg/dL). ResultsOf the 6905 included patients, 2201 (31.9%) were female, and the median (IQR) age was 68.2 (60.1–75.9) years. In all, 1836 (26.6%) patients had severe hyperglycemia. The incidence of AKI within 7 days of ICU admission, ICU mortality, and hospital mortality was significantly higher in patients with severe admission hyperglycemia than those with mild hyperglycemia or no hyperglycemia (80.3% vs. 73.6% and 61.2%, respectively; 2.8% vs. 0.9% and 1.9%, respectively; and 3.4% vs. 1.2% and 2.5%, respectively; all P <0.001). Severe hyperglycemia was a risk factor for 7-day AKI (Model 1: hazard ratio [HR]=1.4809, 95% confidence interval [CI]: 1.3126 to 1.6707; Model 2: HR=1.1639, 95% CI: 1.0176 to 1.3313; Model 3: HR=1.2014, 95% CI: 1.0490 to 1.3760; all P <0.050). Patients with normal glucose levels (glucose levels <140 mg/dL) had a higher 28-day mortality rate than those with severe hyperglycemia (glucose levels ≥200 mg/dL) (4.0% vs. 3.8%, P <0.001). ConclusionsIn post-cardiac surgery patients, severe hyperglycemia within 24 h of ICU admission increases the risk of 7-day AKI, ICU mortality, and hospital mortality. Clinicians should be extra cautious regarding AKI among patients with hyperglycemia at ICU admission after cardiac surgery.

A Study on the Etiology and Clinical Manifestations of Community-Acquired Pneumonia in Adults in Western India.

Community-acquired pneumonia (CAP) is an acute lung infection affecting the alveoli in individuals who have not had recent exposure to healthcare settings. It is characterized by newly detected pulmonary infiltration on a chest X-ray or computed tomography scan, accompanied by at least two of the following symptoms: a new or worsening cough, shortness of breath, increased sputum production, fever or hypothermia, pleuritic chest pain, hypoxia, confusion, or an abnormal WBC count (either leukopenia or leukocytosis). It is a major contributor to global mortality and morbidity, especially in elderly populations. This study aims to investigate the etiology of CAP in our region and analyze the clinical characteristics of patients diagnosed with CAP. This prospective, hospital-based study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pune, a 2,011-bed multispecialty hospital. The study included 100 patients over 18 years old, diagnosed with CAP, and hospitalized between January 2023 and January 2024. All patients underwent a thorough clinical assessment, and sputum cultures were collected on the day of admission. Patients under 18 years old, those who had been hospitalized within the preceding two weeks, individuals with pneumonia caused by tuberculosis oraspiration pneumonia, patients with compromised immune systems, and pregnant women were excluded. The study included 100 patients with a mean age of 53.13 years (±18.31). The most common age group was 59-68 years, which included 25 (25%) cases, followed by the 69-78 yearage group with 18 (18%) cases and the 18-28 yearage group with 15 (15%) cases. The majority were male, with 61 (61%) cases. Common symptoms included fever in 78 cases (78%), chest pain in 69 cases (69%), dyspnea in 65 cases (65%), and cough in 51 cases (51%). Sputum cultures showed growth in 65 cases (65%), with Klebsiella pneumoniae being the most prevalent pathogen in 28cases (43%), followed by Streptococcus pneumoniae in 18 cases (28%). Together, these two pathogens accounted for 46 out of 65 positive samples (70%). This study highlights the clinical profile and rising etiology of K. pneumoniae in CAPin adults in Western India, particularly in the elderly. These findings underscore the need for periodic updates on CAP etiology to inform empirical treatment strategies effectively. Future research should use advanced diagnostics and diverse samples to refine CAP management, with continuous monitoring to update treatment protocols.

NeoGx: Machine-Recommended Rapid Genome Sequencing for Neonates.

Genetic disease is common in the Level IV Neonatal Intensive Care Unit (NICU), but neonatology providers are not always able to identify the need for genetic evaluation. We trained a machine learning (ML) algorithm to predict the need for genetic testing within the first 18 months of life using health record phenotypes. For a decade of NICU patients, we extracted Human Phenotype Ontology (HPO) terms from clinical text with Natural Language Processing tools. Considering multiple feature sets, classifier architectures, and hyperparameters, we selected a classifier and made predictions on a validation cohort of 2,241 Level IV NICU admits born 2020-2021. Our classifier had ROC AUC of 0.87 and PR AUC of 0.73 when making predictions during the first week in the Level IV NICU. We simulated testing policies under which subjects begin testing at the time of first ML prediction, estimating diagnostic odyssey length both with and without the additional benefit of pursuing rGS at this time. Just by using ML to accelerate initial genetic testing (without changing the tests ordered), the median time to first genetic test dropped from 10 days to 1 day, and the number of diagnostic odysseys resolved within 14 days of NICU admission increased by a factor of 1.8. By additionally requiring rGS at the time of positive ML prediction, the number of diagnostic odysseys resolved within 14 days was 3.8 times higher than the baseline. ML predictions of genetic testing need, together with the application of the right rapid testing modality, can help providers accelerate genetics evaluation and bring about earlier and better outcomes for patients.
