Heart and kidney crosstalk: risk factors, clinical features, and short-term outcomes associated with acute kidney injury in patients suffering acute non-ST elevation myocardial infarction

<p><strong>Aim</strong> Acute kidney injury (AKI) presents a high mortality complication in patients with acute myocardial infarction (AMI). Yet, its correlation with non-ST elevation myocardial infarction (NSTEMI) remains neglected in the literature. This study aims to investigate the prevalence, risk factors, clinical features, and short-term outcomes associated with AKI development in patients with acute NSTEMI.<br /><strong>Methods</strong> A one-year prospective observational cohort study involved 170 consecutive patients hospitalized in the Intensive Care Department of the Internal Medicine Clinic at the University Clinical Centre Tuzla diagnosed with acute NSTEMI. Patients were subsequently categorized into AKI and non-AKI groups based on AKI development within 48 hours. Demographic characteristics, laboratory findings, and short-term clinical outcomes were compared between the groups.<br /><strong>Results</strong> Of 170 patients, 31 (18.2%) developed AKI within 48 hours of acute NSTEMI. Significant age differences, blood urea nitrogen (BUN), creatinine, estimated glomerular filtration rate (eGFR), blood glucose level (BGL), C-reactive protein (CRP), and high sensitivity (hs) troponin were observed, making patients with lower baseline kidney function, more extensive myocardial infarction, and a heavier systemic inflammatory response following acute NSTEMI more susceptible to AKI development. In the follow-up period, mortality rates were significantly higher in the AKI group, amounting to 35.5% compared to 10.1% in the non-AKI group. Additionally, mortality increased with the severity of AKI, reaching 100% in AKI stage 2.<br /><strong>Conclusion</strong> This study highlights demographic, clinical and laboratory findings in patients with acute NSTEMI, which contribute to AKI development. Early detection and tailored interventions are crucial in mitigating AKI-associated morbidity and mortality.</p>

Tocilizumab plus Nintedanib for progressive interstitial lung disease in systemic sclerosis: a one-year observational study.

Randomized controlled trials have recently shown that both the IL-6 inhibitor Tocilizumab and the antifibrotic Nintedanib are efficacious for Systemic Sclerosis (SSc)-associated progressive interstitial lung disease (ILD). Since real-world clinical data on Tocilizumab/Nintedanib combination are lacking, we report on their long-term safety and efficacy. Consecutive patients who received off-label Tocilizumab for SSc plus Nintedanib for progressive ILD were retrospectively studied. Adverse events, and changes in Forced Vital Capacity (FVC), Diffucing Capacity for Carbon Monoxide (DLCO) and high resolution chest tomography (HRCT) between baseline and 6 and 12 months were assessed. Tocilizumab/Nintedanib combination was well tolerated by all 20 patients [aged 52 ± 13 years (mean ± SD), 14 women, 15 diffuse SSc, disease duration of 5.7 ± 4.9 years]; 7 of 20 patients received concomitant mycophenolate mofetil safely. No serious adverse events or laboratory abnormalities were noted. Five patients developed persistent diarrhea and 2 of them reduced dosage of Nintedanib. Baseline FVC (74%±12%) and DLCO (45%±10%) remained overall stable both at 6 months (73.5%±13% and 46%±11%, respectively) and 12 months (73%±14% and 45%±11%, respectively), regardless of disease duration. The extent of fibrotic reticular pattern in available pairs of HRCTs (n = 12) remained also stable at 12 months, whereas proportion (%) of ground glass opacities decreased from 29%±16to21%±14% (p = 0.048); improvement in HRCTs by almost 75% was noted in 2 of these12 patients. Tocilizumab/Nintedanib combination for one year was safe and stabilized lung function in real-world SSc patients with progressive ILD. Additional studies of this combination treatment in SSc-ILD are warranted.

Burden of drug-resistant tuberculosis by the GeneXpert MTB/RIF assay and its clinico-epidemiological aspects at a tertiary care hospital in West Bengal

Multidrug -resistant tuberculosis (MDRTB) is a serious threat to mankind. India has the highest number of MDRTB cases, although majority remain undiagnosed due to inadequate diagnostic infrastructure, leading to increased community transmission and mortality. This one-year observational retrospective study highlighted the effectiveness of the National Tuberculosis Elimination Program (NTEP) for prompt detection of drug-resistant TB by GeneXpert MTB/RIF assay and revealed its associated clinico-epidemiological factors. The overall detection rates of MTB and RRTB were 20.70 % and 20.86 % respectively. The pediatric population had 7.69 % rifampicin resistance, and HIV was strongly associated with the development of TB and RRTB (P < 0.01).

Dilated Cardiomyopathy in the Cardiology Department of the CHU of Casablanca: A One-Year Observational Study

Dilated Cardiomyopathy (DCM) is defined by a left ventricle (LV) with reduced systolic function (&lt;45%) and dilation (LV volume &gt; 90 ml/m²), excluding coronary artery disease or sufficient load conditions to explain it. The etiologies are multiple and increasingly well-known. We conducted a single-centre, retrospective observational study within the cardiology department of the CHU IBN ROCHD in Casablanca, Morocco, over one year. The main objective was to describe the characteristics and particularities of patients followed for DCM. The diagnosis is based only on echocardiography, after exclusion of an ischemic cause, severe valvular disease, and congenital heart disease. During the study, 44 patients were included, with a male predominance of 63.6% versus 36.4%. The average age was 60 ± 16.8 years. The initial presentation of cardiomyopathy showed that 73% of patients were admitted with heart failure (HF). The mean left ventricular ejection fraction (LVEF) was 30.2 ± 7.9%. Among the attributed etiologies, idiopathic DCM was the main cause reported in 59% of cases, followed by systemic lupus erythematosus (14%) and myocarditis (14%). In our sample, treatment was based on HF management, including beta-blockers, renin-angiotensin system blockers, SGLT2 inhibitors, and aldosterone antagonists. Implantation of a defibrillator for primary prevention concerned only one patient (3%) of the 33 patients for whom the theoretical indication was retained.

Investigating the Prevalence, Gender Predilection, and Inheritance Patterns of Genodermatoses: A Tertiary Hospital Study.

Genodermatoses encompass a spectrum of hereditary skin disorders stemming from mutations in genes pivotal for skin development, structure, and function. This study investigated the prevalence, gender predilection, and inheritance patterns of genodermatoses in a tertiary-level hospital through a one-year observational study. Among 157,051 dermatology outpatient department patients, 105 cases of genodermatoses were diagnosed, yielding a prevalence rate of 0.067%. Hamartoneoplastic syndromes and inherited disorders of cornification were the most prevalent subgroups, with neurofibromatosis type 1 and tuberous sclerosis complex 1 leading within these categories. The average age at presentation varied among different subgroups. A 2:1 male-to-female ratio was observed across all subgroups. Autosomal dominant inheritance was predominant. A positive family history in 46 cases and consanguinity among parents in 28 instances was reported. Genodermatoses pose diagnostic challenges due to their clinical complexity and rarity, which is compounded by limited epidemiological data. Molecular diagnosis advancements offer insights into genotype-phenotype correlations and facilitate genetic counseling and prenatal diagnosis (PND). Raising awareness among healthcare professionals and the public is critical for improving the quality of life for affected individuals.

Persistent increased severity of cannabis use disorder symptoms in adolescents compared to adults: a one-year longitudinal study.

Adolescence is a developmental period characterised by increased vulnerability to cannabis use disorder (CUD). However, previous investigations of this vulnerability have relied on cross-sectional comparisons and lack a detailed assessment of cannabis quantity, a potentially important confounding factor. Here, we aimed to investigate the one-year course of CUD in adolescents compared to adults who currently use cannabis, adjusting for a comprehensive measure of cannabis quantity. Data are from a one-year observational longitudinal study (CannTeen) of adolescents and adults who currently used cannabis regularly with five waves of assessment at 3-monthly intervals, based in London, UK. Participants were n = 70 adults (26-29, 45.7% female), who did not regularly use cannabis when they were under age 18, and n = 76 adolescents (16-17, 50.0% female). The exposure was adolescent (compared to adult) frequent cannabis use. The primary outcome was CUD symptoms measured using the cannabis use disorder identification test revised (CUDIT-R) at five time points. Models were adjusted for cannabis quantity using mean weekly standard THC units (one unit = 5mg THC). Other covariates included gender, and whether each session occurred before or during the COVID-19 pandemic. In models adjusted for pre-registered covariates, adolescents scored 3.7 points higher on the CUDIT-R compared to the adult group across the 5 assessment waves (3.66 95% CIs 1.99, 5.34). There was also evidence of a linear reduction in symptoms over time in both groups (-0.47, 95%CIs -0.67, -0.27). Adolescents had persistently increased CUD symptoms compared to adults across the 12-month period. This association was robust after adjusting for the quantity of cannabis consumed and other covariates.

The Natural History of Retinal Sensitivity Loss in Diabetic Macular Ischemia over One Year Evaluated by Microperimetry.

Background/Objectives: This one-year prospective observational study, conducted at two centers, aimed to report the natural history of retinal sensitivity (RS) loss in diabetic macular ischemia (DMI). Methods: Patients with stable-treated proliferative diabetic retinopathy (PDR) were recruited if there was evidence of DMI on optical coherence tomography angiography, defined as a foveal avascular zone ≥ 0.5 mm2 or parafoveal capillary dropout ≥ 1 quadrant. The minimal visual acuity required for performing microperimetry (MP) was ≥54 Early Treatment Diabetic Retinopathy Study letters (Snellen equivalent 20/80). The overall RS (oRS) and pointwise sensitivity (PWS) within the 3 × 3 mm macula were assessed at baseline and twelve months. A value <25 decibels (dB) was defined as impaired RS, and a decrease of 2 and 7 dB was regarded as mild and severe loss, respectively. Results: A total of 88 patients (97 eyes) were included. No statistically significant MP changes were detected at one year. However, 10% of the cohort lost oRS ≥ 2 dB, and 73% lost ≥2 dB PWS in ≥5 loci, whereas 1% lost oRS ≥ 7 dB, and 4% lost ≥7 dB PWS in ≥5 loci. The foveola and temporal parafovea were the most vulnerable to severe RS loss. Compared to their counterpart, eyes with baseline oRS ≥ 25 dB had significantly more RS loss in the macula and superior parafovea (55% versus 32% and 53% versus 28%, both p = 0.01). Conclusions: Rather than oRS loss, ≥2 dB loss in PWS in ≥5 loci is a more feasible outcome measure for clinical trials in DMI.

Identifying Depression Subtypes and Investigating their Consistency and Transitions in a 1-Year Cohort Analysis

Introduction Major Depressive Disorder (MDD) is a complex mental health condition characterized by a wide spectrum of symptoms. According to the Diagnostic Statistical Manual 5 (DSM-5) criteria, patients can present with up to 1,497 different symptom combinations, yet all receive the same MDD diagnosis. This diversity in symptom presentation poses a significant challenge to understanding the disorder in the wider population. Subtyping offers a way to unpick this phenotypic diversity and enable improved characterization of the disorder. According to reviews, MDD subtyping work to date has lacked consistency in results due to inadequate statistics, non-transparent reporting, or inappropriate sample choice. By addressing these limitations, the current study aims to extend past phenotypic subtyping studies in MDD.Objectives(1) To investigate phenotypic subtypes at baseline in a sample of people with MDD;(2) To determine if subtypes are consistent between baseline 6- and 12-month follow-ups; and(3) To examine how participants move between subtypes over time.Methods This was a secondary analysis of a one-year longitudinal observational cohort study. We collected data from individuals with a history of recurrent MDD in the United Kingdom, the Netherlands and Spain (N=619). The presence or absence of symptoms was tracked at three-month intervals through the Inventory of Depressive Symptomatology: Self-Report (IDS-SR) assessment. We used latent class and three-step latent transition analysis to identify subtypes at baseline, determined their consistency at 6- and 12-month follow-ups, and examined participants’ transitions over time.ResultsWe identified a 4-class solution based on model fit and interpretability, including (Class 1) severe with appetite increase, (Class 2), severe with appetite decrease, (Class 3) moderate, and (Class 4) low severity. The classes mainly differed in terms of severity (the varying likelihood of symptom endorsement) and, for the two more severe classes, the type of neurovegetative symptoms reported (Figure 1). The four classes were stable over time (measurement invariant) and participants tended to remain in the same class over baseline and follow-up (Figure 2).Image:Image 2:Conclusions We identified four stable subtypes of depression, with individuals most likely to remain in their same class over 1-year follow-up. This suggests a chronic nature of depression, with (for example) individuals in severe classes more likely to remain in the same class throughout follow-up. Despite the vast heterogeneous symptom combinations possible in MDD, our results emphasize differences across severity rather than symptom type. This raises questions about the meaningfulness of these subtypes beyond established measures of depression severity. Implications of these findings and recommendations for future research are made.Disclosure of Interest C.

Mean Activated Clotting Time of Patients Receiving Intravenous Heparin and Undergoing Primary Percutaneous Coronary Intervention for ST Elevation Myocardial Infarction.

Introduction The most prevalent cause of death is acute myocardial infarction (AMI). Primary percutaneous coronary intervention (PPCI) has replaced thrombolysis as the recommended therapeutic option for individuals with ST-segment elevation myocardial infarction (STEMI). However, more effective anticoagulation regimes are required for PCI due to the limitations of unfractionated heparin. Objective This study aimed to ascertain the connection between the mean activated clotting time and the risk of bleeding and infarcts in individuals receiving intravenous heparin during PPCI for STEMI. Methods This was a one-year prospective observational study carried out at the National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan. Results The majority (70.15%) were male, with a mean age of 56.08 ± 8.92 years. Following PPCI, the average active clotting time (ACT) was 350.56 ± 39.62 seconds (range 255 to 453), compared to the pre-PPCI mean of 504.15 ± 38.98 seconds. ACT was considerably higher in female patients, smokers, and overweight patients. The mean ACT was not significantly higher in patients with hypertension (HTN) and dyslipidemia (DLD). Conclusion The ACT range in this investigation was 255 to 453 seconds, and there was no discernible relationship between ACT readings and problems related to bleeding and ischemia. To determine who is more at risk, bleeding risk models should be used and improved further before catheterization.

Evaluation of hybrid closed-loop insulin delivery system in type 1 diabetes in real-world clinical practice: One-year observational study.

In 2016, the Food and Drug Administration approved the first hybrid closed-loop (HCL) insulin delivery system for adults with type 1 diabetes (T1D). There is limited information on the impact of using HCL systems on patient-reported outcomes (PROs) in patients with T1D in real-world clinical practice. In this independent study, we evaluated glycemic parameters and PROs over one year of continuous use of Medtronic's 670G HCL in real-world clinical practice. To assess the effects of hybrid closed loop system on glycemic control and quality of life in adults with T1D. We evaluated 71 patients with T1D (mean age: 45.5 ± 12.1 years; 59% females; body weight: 83.8 ± 18.7 kg, body mass index: 28.7 ± 5.6 kg/m2, A1C: 7.6% ± 0.8%) who were treated with HCL at Joslin Clinic from 2017 to 2019. We measured A1C and percent of glucose time-in-range (%TIR) at baseline and 12 months. We measured percent time in auto mode (%TiAM) for the last two weeks preceding the final visit and assessed PROs through several validated quality-of-life surveys related to general health and diabetes management. At 12 mo, A1C decreased by 0.3% ± 0.1% (P = 0.001) and %TIR increased by 8.1% ± 2.5% (P = 0.002). The average %TiAM was only 64.3% ± 32.8% and was not associated with A1C, %TIR or PROs. PROs, provided at baseline and at the end of the study, showed that the physical functioning submodule of 36Item Short-Form Health Survey increased significantly by 22.9% (P < 0.001). Hypoglycemia fear survey/worry scale decreased significantly by 24.9% (P < 0.000); Problem Areas In Diabetes reduced significantly by -17.2% (P = 0.002). The emotional burden submodules of dietary diversity score reduced significantly by -44.7% (P = 0.001). Furthermore, analysis of Clarke questionnaire showed no increase in awareness of hypoglycemic episodes. WHO-5 showed no improvements in subject's wellbeing among participants after starting the 670G HCL system. Finally, analysis of Pittsburgh Sleep Quality Index showed no difference in sleep quality, sleep latency, or duration of sleep from baseline to 12 mo. The use of HCL in real-world clinical practice for one year was associated with significant improvements in A1C, %TIR, physical functioning, hypoglycemia fear, emotional distress, and emotional burden related to diabetes management. However, these changes were not associated with time in auto mode.

Study on location of cerebral lesion among patients with hemorrhagic cerebrovascular accident

Background: In hemorrhagic cerebrovascular accident, bleeding occurs directly into the brain parenchyma. Intracerebral hemorrhage usually occurs at certain sites in the brain, i.e., thalamus, putamen, cerebellum, and brain stem. The surrounding area of brain may be damaged by pressure produced by the mass effect of the hematoma. Increase in intracranial pressure occurs. Aims and Objectives: The aim and objective of the study are to compare the localization of cerebral lesions with the frequency of intraventricular hemorrhage and to study the prognosis of hemorrhagic cerebrovascular accident (CVA) as per its anatomical location in computed tomography (CT) scan. Materials and Methods: One-year observational cross-sectional study was conducted in 60 patients with CT scan diagnosed hemorrhagic CVA. Results: Regarding the site of the hemorrhagic CVA, the most commonly affected area was basal ganglia (46.7%) followed by thalamus (18.3%); other areas include pons (8.3%), paraventricular (8.3%), cerebellar (6.7%), lobar (5%), internal capsule (3.3%), and intraventricular (3.3%). Conclusion: This study reflects a spectrum of cerebral location of hemorrhagic stroke which may help in the management of hemorrhagic CVA patients.

Comparative Incidence of Pyogenic and Amoebic Liver Abscesses in Trauma and Emergency Patients at Indira Gandhi Institute of Medical Sciences (IGIMS), Patna: A One-Year Observational Study.

Liver abscesses, particularly pyogenic and amoebic types, pose a significant healthcare challenge, especially in developing countries. Accurate differentiation and effective treatment of these abscess types are crucial in emergency medical settings. This study aims to analyze the incidence, clinical characteristics, and treatment outcomes of pyogenic and amoebic liver abscesses in a trauma and emergency department setting. Conducted at the Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, this one-year observational study involved 100 patients diagnosed with liver abscesses. The study employed a comprehensive approach, examining incidence rates, demographic trends, clinical presentations, treatment modalities, and outcomes, including recurrence rates. The study observed a higher incidence of pyogenic liver abscesses, accounting for 60% of cases (n=60), compared to amoebic liver abscesses, which constituted 40% (n=40). In terms of demographics, pyogenic liver abscesses were more prevalent among older males, with the average age being 48 years, and 70% (n=42) of the patients were male. In contrast, amoebic liver abscess patients had an average age of 42 years, with 60% (n=24) being male. Key clinical findings revealed that pyogenic liver abscess cases (n=60) had higher white blood cell counts and elevated liver enzyme levels than those with amoebic liver abscesses (n=40). The treatment outcomes indicated high success rates for both types of liver abscesses. Pyogenic liver abscesses had a success rate of 90% (n=54), while amoebic liver abscesses showed a slightly higher success rate at 95% (n=38). However, there was a notable difference in recurrence rates: pyogenic liver abscesses had a recurrence rate of 8.3% (n=5), whereas amoebic liver abscesses had a lower recurrence rate of 2.5% (n=1). The logistic regression analysis conducted to identify potential predictors of treatment success did not reveal any statistically significant factors across both types of liver abscesses. The study highlights a higher incidence of pyogenic liver abscesses in an urban Indian healthcare setting and the complexity of predicting treatment outcomes based on demographic and clinical factors. The findings emphasize the need for nuanced clinical approaches and vigilant post-treatment monitoring, especially for pyogenic liver abscesses. They also underscore the importance of further research to explore additional variables influencing liver abscess treatment outcomes.

Evaluation of Safety of Spinal Anaesthesia in Patients Receiving Perioperative Antithrombotic Therapy Undergoing Infrainguinal Revascularisation Surgeries: A One-Year Prospective Clinical Research

Objective: To evaluate anaesthetic outcome, patient outcome and timing of perioperative antithrombotic therapy in relation to intrathecal injection in patients undergoing infrainguinal revascularisation surgery, for peripheral artery disease (PAD) in spinal anaesthesia.Material and Methods: A one-year prospective observational study was conducted; from May 2019 to May 2020, in a tertiary care centre. This included all consecutive patients undergoing infrainguinal revascularisation surgery for PAD under spinal anaesthesia. Preoperative antithrombotics were stopped, as per standard guidelines, to achieve a normal coagulation profile before spinal anaesthesia. Perioperative data related to the patients, antithrombotics, anaesthesia, surgery, and complications were recorded. Primary outcomes measured were anaesthetic outcome in terms of spinal success and spinal safety. Secondary outcomes measured were timing of perioperative antithrombotic therapy in relation to intrathecal injection and patient outcomes defined as: good, morbidity or mortality.Results: A total of 102 patients were evaluated, with a mean age of 54.69±16.36 years (91% males, 9% females): 58% had medical comorbidities. A single dose of intravenous (IV) unfractionated heparin (5,000-7,500 IU) was given intraoperatively at 24.97±3.69 minutes after intrathecal injection. Anaesthetic outcome was good in all patients; in terms of spinal safety (100%), as none of the patients developed spinal related complications. All had spinal success (100%), as no patient required conversion to general anaesthesia. Postoperatively, 98% (100) of patients had good outcomes, and mortality only occurred in 2% (2) of patients.Conclusion: Spinal anaesthesia is safe and effective for infrainguinal revascularisation surgery. If the patient has a normal preoperative coagulation profile, and the timeline to stop antithrombotic therapy is strictly followed, administration of IV unfractionated heparin (5,000-7,500 IU); at approximately 25 minutes after intrathecal injection, was found to be safe.

Comparative Evaluation of Broth Microdilution With Disc Diffusion and VITEK 2 for Susceptibility Testing of Colistin on Multidrug-Resistant Gram-Negative Bacteria.

Background The rise of antibiotic resistance, particularly in Gram-negative bacteria, poses a significant global health threat. Colistin, a last-resort antibiotic, has witnessed renewed use. However, accurate susceptibility testing for colistin is challenging, with various methods available, leading to potential discrepancies. Ensuring reliable testing is crucial for effective patient treatment and antimicrobial stewardship. This study addresses the need to compare different colistin susceptibility testing methods, providing insights into their accuracy and relevance in clinical settings. Methods In this one-year prospective observational cross-sectional study conducted atIndira Gandhi Institute of Medical Sciences (IGIMS), Bihar, India, atertiary care hospital from July 2021 to June 2022, we aimed to evaluate the concordance between two widely used methods, VITEK 2 and Disc Diffusion, for antibiotic susceptibility testing in clinical multidrug-resistant Gram-negative bacterial isolates. These isolates, including species like Klebsiella pneumoniae, Acinetobacter baumannii, Klebsiella oxytoca, Pseudomonas aeruginosa, Citrobacter freundii, and Escherichia coli, were isolated from various clinical specimens. After rigorous species-level identification and quality control measures, antibiotic susceptibility testing was performed using both methods, and their agreement was assessed through Percentage Agreement analysis. Results In our study, we isolated and identified bacterial isolates from 105 patients, with a mean age of 47.30 years, demonstrating a wide age range. Pus samples were the most common type (25.7%), and K. pneumoniae was the most prevalent organism (45.7%). Antibiotic resistance patterns revealed significant challenges in treating infections caused by K. pneumoniae and A. baumannii, with resistance rates exceeding 70% for certain antibiotics. Among the 48 isolates of K. pneumoniae, the agreement was 93.8%, with 89.6% being sensitive and 6.3% being resistant by Disc Diffusion, while VITEK 2 indicated 0% resistance. E. coli isolates (n=21) had an agreement of 90.5%, with 90.5% sensitivity and 9.5% resistance by Disc Diffusion, and no resistance by VITEK 2. Conclusion The comparative analysis of antibiotic susceptibility testing methods reveals the superior performance of the VITEK 2 system, particularly in sensitivity and negative predictive value, emphasizing its potential as a reliable tool for guiding antibiotic therapy decisions.

Background: By therapeutic apheresis is to remove a pathologic element from blood or to modulate cellular function. By this study we observed, complications after the therapeutic plasma exchange (TPE) within 24 hours with respect to patient’s demographic profiles and procedural variations. Methods: One-year prospective observational study conducted by the Department of Transfusion Medicine in collaboration with the Medicine Department, King George’s Medical University, Lucknow India. Results: In our study total of 60 cases and total of 150 TPE cycles were performed. Maximum mean age (36±4) was observed for cough and vomiting both and maximum mean BMI was observed followed for Infection at phlebotomy site (36.34±5.09). Maximum mean variation of hemoglobin was observed for vomiting (2.28±0.00), followed by internal bleeding. Maximum mean variation of activated partial thromboplastin time (aPTT) was observed for cough (22.05±0.34), followed by vomiting. Maximum mean variation of prothrombin time (PT) was observed for hypothermia (13.16±10.47), followed by internal bleeding. Maximum mean variation of S. creatinine was observed for abdominal discomfort (0.23±1.54), followed by vomiting. Maximum mean variation of systolic blood pressure (SBP) was observed for cough (7.00±5.20), followed by bipedal edema. Maximum mean variation of SpO2 was observed for death. Conclusions: Complication within 24 hours after the procedure was abdominal discomfort mainly in males with a correlation with body mass index (BMI). We observed significant positive association with complication versus APTT, PT, S. urea, S. creatinine, pulse, SBP, SpO2 and BMI. This emphasizes the decreasing trend of the complications with the increase in number of cycles.

Examining Mobile Health App Engagement In A North American Employee Population: A One-year Longitudinal Observational Study

Factors associated with hospital admission and 30-day readmission for children less than 18 years of age in 2018 in France: a one-year nationwide observational study

BackgroundNationwide data for children for short-stay hospitalisation (SSH) and associated factors are scarce. This retrospective study of children in France < 18 years of age followed after their birth or birthday in 2018 focused on at least one annual SSH, stay < 1 night or ≥ 1 night, or 30-day readmission ≥ 1 night.MethodsChildren were selected from the national health data system (SNDS), which includes data on long-term chronic disease (LTD) status with full reimbursement and complementary universal coverage based on low household income (CMUC). Uni and multivariate quasi-Poisson regression were applied for each outcome.ResultsAmong 13.211 million children (94.4% population, 51.2% boys), CMUC was identified for 17.5% and at least one LTD for 4% (0-<1 year: 1.5%; 14-<18 year: 5.2%). The most frequent LTDs were pervasive developmental diseases (0.53%), asthma (0.24%), epilepsy (0.17%), and type 1 diabetes (0.15%). At least one SSH was found for 8.8%: SSH < 1 night (4.9%), SSH ≥ 1 night (4.5%), readmission (0.4%). Children with at least one SSH were younger (median 6 vs. 9 years) and more often had CMUC (21%), a LTD (12%), an emergency department (ED) visit (56%), or various primary healthcare visits than all children. Those with a SSH ≥1 night vs. < 1 night were older (median: 9 vs. 4 years). They had the same frequency of LTD (13.4%) but more often an ED visit (78% vs. 42%). Children with readmissions were younger (median 3 years). They had the highest levels of CMUC (29.3%), LTD (34%), EDs in their municipality (35% vs. 29% for the whole population) and ED visits (87%). In adjusted analysis, each outcome was significantly less frequent among girls than boys and more frequent for children with CMUC. LTDs with the largest association with SSH < 1 night were cystic fibrosis, sickle cell diseases (SCD), diabetes type 1, those with SSH ≥1 night type 1 diabetes epilepsy and SCD, and those for readmissions lymphoid leukaemia, malignant neoplasm of the brain, and SCD. Among all SSH admissions of children < 10 years, 25.8% were potentially preventable.ConclusionHigher SSH and readmission rates were found for children with certain LTD living in low-income households, suggesting the need or increase of specific policy actions and research.

Application of Otoform to Study Variations of Sinus Tympani: A Novel Technique.

The sinus tympani is a deep pocket of varying dimensions situated in the retrotympanum. It lies medial to the facial nerve thereby making surgical access difficult. It is this area which is frequently involved in chronic otitis media attico-antral type. Removal of disease from sinus tympani is cumbersome and expedites Cholesteatoma Recidivism. In India, very limited studies have been conducted describing the variations of Sinus tympani. Hence, this study is dedicated to estimating it's variations in volume. This is a one-year Observational Cross-sectional study conducted between January 2020 to December 2020 in Temporal Bone Dissection Lab of Department of Otorhinolaryngology and Head and Neck Surgery, J. N. Medical College, KAHER, Belgaum. 40 Human temporal bone (both left and right) have been dissected. The middle ear cavity was filled carefully with a moulding material i.e. Otoform. Once set, a 3-dimensional model of the middle ear cavity was made, which was removed carefully without causing any damage. The volume of the middle ear cavity was calculated. The other contents and parameters were measured using a measuring probe. Forty bones were dissected. The volume of the sinus tympani was measured to be 8.77 cubic mm with a range of 6.5 cubic mm to. 10.9 cubic mm hence showing that sinus tympani show a larger variability in terms of size, shape and volume. The ponticulus was Complete in 65% of the cases (26 bones) and incomplete in 35% of the cases (14 bones). The ponticulus and subiculum were found to be complete in a well pneumatized mastoid bone. The volume of the middle ear cavity was measured to be 1.17 cubic cm. The sinus tympani volume was calculated in this study employing a novel technique called the Otoform mould in cadaveric temporal bones, enabling for accurate measurement. The study concluded that sinus tympani showed a wide range in volume thus owing that it is the structure which has highest variability in terms of size and shape in the middle ear.

Carbohydrate intake in young female cross-country skiers is lower than recommended and affects competition performance.

(1) To evaluate if energy availability (EA), macronutrient intake and body composition change over four training periods in young, highly trained, female cross-country skiers, and (2) to clarify if EA, macronutrient intake, body composition, and competition performance are associated with each other in this cohort. During a one-year observational study, 25 female skiers completed 3-day food and training logs during four training periods: preparation, specific preparation, competition, and transition periods. A body composition measurement (bioimpedance analyzer) was performed at the end of the preparation, specific preparation, and competition periods. Competition performance was determined by International Ski Federation (FIS) points gathered from youth national championships. EA (36-40 kcal·kg FFM-1·d-1) and carbohydrate (CHO) intake (4.4-5.1 g·kg-1·d-1) remained similar, and at a suboptimal level, between training periods despite a decrease in exercise energy expenditure (p = 0.002) in the transition period. Higher EA (r = -0.47, p = 0.035) and CHO intake (r = -0.65, p = 0.002) as well as lower FM (r = 0.60, p = 0.006) and F% (r = 0.57, p = 0.011) were associated with lower (better) FIS-points. CHO intake was the best predictor of distance competition performance (R2 = 0.46, p = 0.004). Young female cross-country skiers had similar EA and CHO intake over four training periods. Both EA and CHO intake were at suboptimal levels for performance and recovery. CHO intake and body composition are important factors influencing competition performance in young female cross-country skiers.

Real-World Performance of First- Versus Second-Generation Automated Insulin Delivery Systems on a Pediatric Population With Type 1 Diabetes: A One-Year Observational Study.

The aim of this single-center observational study was to assess the real-world performance of first- and second-generation automated insulin delivery (AID) systems in a cohort of children and adolescents with type 1 diabetes over a one-year follow-up. Demographic, anamnestic, and clinical data of the study cohort were collected at the start of automatic mode. Data on continuous glucose monitoring metrics, system settings, insulin requirements, and anthropometric parameters at three different time points (start period, six months, 12 months) were retrospectively gathered and statistically analyzed. Fifty-four individuals (55.6% of females) aged 7 to 18 years switching to AID therapy were included in the analysis. Two weeks after starting automatic mode, subjects using advanced hybrid closed-loop (AHCL) showed a better response than hybrid closed-loop (HCL) users in terms of time in range (P = .016), time above range 180 to 250 mg/dl (P = .022), sensor mean glucose (P = .047), and glycemia risk index (P = .012). After 12 months, AHCL group maintained better mean sensor glucose (P = .021) and glucose management indicator (P = .027). Noteworthy, both HCL and AHCL users achieved the recommended clinical targets over the entire study period. The second-generation AID system registered longer time spent with automatic mode activated and fewer shifts to manual mode at every time point (P < .001). Both systems showed sustained and successful glycemic outcomes in the first year of use. However, AHCL users achieved tighter glycemic targets, without an increase of hypoglycemia risk. Improved usability of the device may also have contributed to optimal glycemic outcomes by ensuring better continuity of the automatic mode activation.
