Derivation of the Difficult Airway Physiological Score (DAPS) in adults undergoing endotracheal intubation in the emergency department

BackgroundPrediction of serious outcomes among patients with physiological instability is crucial in airway management. In this study, we aim to develop a score to predict serious outcomes following intubation in critically ill adults with physiological instability by using clinical and laboratory parameters collected prior to intubation.MethodThis single-center analytical cross-sectional study was conducted in the Emergency Department from 2016 to 2020. The airway score was derived using the transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) methodology. To gauge model’s performance, the train-test split technique was utilized. The discrete random number generation approach was used to divide the dataset into two groups: development (training) and validation (testing). The validation dataset’s instances were used to calculate the final score, and its validity was measured using ROC analysis and area under the curve (AUC). By computing the Youden’s J statistic using the metrics sensitivity, specificity, positive predictive value, and negative predictive value, the discriminating factor of the additive score was determined.ResultsThe mean age of the 1021 patients who needed endotracheal intubations was 52.2 years (± 17.5), and 632 (62%) of them were male. In the development dataset, there were 527 (64.9%) physiologically difficult airways, 298 (36.7%) post-intubation hypotension, 124 (12%) cardiac arrest, 347 (42.7%) shock index > 0.9, and 456 [56.2%] instances of pH < 7.3. On the contrary, in the validation dataset, there were 143 (68.4%) physiologically difficult airways, 33 (15.8%) post-intubation hypotension, 41 (19.6%) cardiac arrest, 87 (41.6%) shock index > 0.9, and 121 (57.9%) had pH < 7.3, respectively. There were 12 variables in the difficult airway physiological score (DAPS), and a DAPS of 9 had an area under the curve of 0.857. The accuracy of DAPS was 77%, the sensitivity was 74%, the specificity was 83.3%, and the positive predictive value was 91%.ConclusionDAPS demonstrated strong discriminating ability for anticipating physiologically challenging airways. The proposed model may be helpful in the clinical setting for screening patients who are at high risk of deterioration.

Functional outcome and analysis of factors affecting health-related quality of life of surgically managed pelvic ring fractures: a cross-sectional study.

Pelvic ring fractures, particularly those involving the posterior pelvis, pose significant challenges due to their inherent instability. The posterior pelvic ring is critical in providing structural support and stability to the pelvis. This study evaluates the functional outcomes and health-related Quality of life (HRQOL) of patients who underwent internal fixation for unstable pelvic fractures. Various factors influencing the outcomes are also investigated. A single-center cross-sectional study was conducted on patients with unstable sacral fractures treated with posterior tension band plate or sacroiliac plating with or without symphyseal plating between 2016 and 2020. Patient demographics, injury mechanisms, associated injuries, surgical details, complications, and return-to-work data were collected. HRQOL was assessed using specific pelvic fracture instruments and general HRQOL questionnaires. Logistic regression analysis was performed to identify factors associated with lower SF-12 and SF-36 scores RESULTS: The study included 54 patients, predominantly males (55.6%), aged 18-70 years, with high-energy trauma mechanisms, such as road traffic accidents and occupational injuries. The majority of patients had lateral compression pelvic fractures. Overall, the functional outcomes were favorable, with excellent or good outcomes observed in 86.1% of cases. Patients with associated injuries, such as abdominal, chest, or head injuries, were likelier to have lower SF-12 physical component scores. Sexual satisfaction scores remained stable for most patients post-surgery. This study highlights the favorable functional outcomes and HRQOL for patients undergoing fixation for unstable pelvic ring fractures. Younger, working-age males were the most commonly affected demographic. Associated injuries significantly affected physical HRQOL scores. Despite high-energy trauma, patients generally reported satisfactory sexual function post-surgery.

Risk factors and a nomogram for predicting cognitive frailty in Chinese patients with lung cancer receiving drug therapy: A single-center cross-sectional study.

To identify independent factors of cognitive frailty (CF) and construct a nomogram to predict cognitive frailty risk in patients with lung cancer receiving drug therapy. In this cross-sectional study, patients with lung cancer undergoing drug therapy from October 2022 to July 2023 were enrolled. The data collected includes general demographic characteristics, clinical data characteristics and assessment of tools for cognitive frailty and other factors. Logistic regression was harnessed to determine the influencing factors, R software was used to establish a nomogram model to predict the risk of cognitive frailty. The enhanced bootstrap method was employed for internal verification of the model. The performance of the nomogram was evaluated by using calibration curves, the area under the receiver operating characteristic curve, and decision curve analysis. A total of 372 patients were recruited, with a cognitive frailty prevalence of 56.2%. Age, education background, diabetes mellitus, insomnia, sarcopenia, and nutrition status were identified as independent factors. Then, a nomogram model was constructed and patients were classified into high- and low-risk groups with a cutoff value of 0.552. The internal validation results revealed good concordance, calibration and discrimination. The decision curve analysis presented prominent clinical utility. The prevalence of cognitive frailty was higher in lung cancer patients receiving drug therapy. The nomogram could identify the risk of cognitive frailty intuitively and simply in patients with lung cancer, so as to provide references for early screening and intervention for cognitive frailty at the early phases of drug treatment.

Revision of the brief international classification of functioning, disability and health core set for multiple sclerosis: a study of the comprehensive icf core set for multiple sclerosis with participants referred for work ability assessment.

To evaluate the Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set for multiple sclerosis with regard to the Brief ICF Core Set for multiple sclerosis. Descriptive cross-sectional single-centre study. A total of 151 participants (99 females/52 males, mean age 49 years) referred for work ability assessment. Data were collected from clinical recordings and by telephone interview. Among 33 Body Functions, 14 were impaired in over 60% of the participants, and 6 in over 75%. These 6 most impaired functions were related to exercise tolerance (b455), urination (b620), muscle power (b730), motor reflex (b750), control of voluntary movement (b760) and gait pattern (b770). Among 54 Activities and Participation categories, 8 were impaired in over 60% of the participants, and 3 were impaired in over 75%. The latter activities were related to walking (d450), moving around (d455) and moving around using equipment (d465). Among the 36 Environmental categories, most were facilitators, except for temperature (e2250) and employment (e590). The latter category was both a facilitator and a barrier. These results suggest additional categories that should be included into the Brief ICF Core Set, to improve its representation of the complex disability of multiple sclerosis.

Stability of standardized uptake values for quantitative bone SPECT for jawbone lesions: a single-center cross-sectional study

BackgroundThe long time required for bone uptake of radiopharmaceutical material after injection for bone scintigraphy is a burden for patients with poor health. Thus, to assess whether the uptake time could be reduced for single-photon emission computed tomography (SPECT) of the jawbone, this study evaluated differences in maximum standardized uptake values (SUVmax) within patients using SPECT imaging at 2 and 3 hours after radiopharmaceutical injection.MethodsA total of 33 patients undergoing treatment or in post-treatment follow-up for medication-related osteonecrosis of the jaw, who visited our hospital between July 2020 and August 2021 and could receive SPECT twice on the same day, were enrolled in the study. Patients were injected with technetium-99 m hydroxymethylene diphosphonate (Tc-99 m HMDP) intravenously. The SUVmax for healthy parietal bones and jawbone lesions were calculated from the SPECT images using quantitative analysis software, and the SUVmax were compared between 2- and 3-hour uptake times.ResultsAfter exclusion, 30 patients were included in the study. In the 2-hour and 3-hour images, the median SUVmax of the parietal bones were 1.90 and 1.81, respectively, and those of the jawbone lesions were 9.25 and 9.39, respectively. The limits of agreement (LOA) ranged from − 0.33 to 0.25 in the parietal bones, and the %LOA ranged from − 9.8 to 17.3% in the jawbone lesions, showing high equivalence between the two uptake durations. The SUVmax showed no clinical differences between the 2- and 3-hour uptake durations for Tc-99 m HMDP SPECT of the jawbone.ConclusionsThe results of this study justify a 2–3-hour uptake window when performing quantitative SPECT of the jawbone. Therefore, the minimum uptake time can potentially be reduced to only 2 hours.

Screening for Peripheral Vascular Stiffness in Lipedema Patients by Automatic Electrocardiogram-Based Oscillometric Detection.

Body mass index (BMI) is seen as a predictor of cardiovascular disease (CVD) in lipedema patients. A valid predictor of CVD is increased aortic stiffness (IAS), and previous research described IAS in lipedema. However, it is not known if this applies to all patients. In this cross-sectional single-center cohort study, peripheral pulse wave velocity (PWV) as a non-invasive indicator of aortic stiffness was measured in 41 patients with lipedema, irrespective of stage and without pre-existing cardiovascular conditions or a history of smoking and a maximum body mass index (BMI) of 35 kg/m2. Automatically electrocardiogram-triggered oscillometric sensor technology by the Gesenius-Keller method was used. Regardless of the stage of lipedema disease, there was no significant difference in PWV compared to published standard values adjusted to age and blood pressure. BMI alone is not a predictor of cardiovascular risk in lipedema patients. Measuring other anthropometric factors, such as the waist-hip ratio or waist-height ratio, should be included, and the existing cardiovascular risk factors, comorbidities, and adipose tissue distribution for accurate risk stratification should be taken into account. Automated sensor technology recording the PWV represents a valid and reliable method for health monitoring and early detection of cardiovascular risks.

Renal function and cardiovascular risk in overweight patients

Background. Currently, in most countries of the world, there is a tendency for an annual increase in the proportion of overweight people (OW). Studies performed in various age groups and devoted to the relationship of OW with the functional state of the kidneys show contradictory results.The aim: to study the functional state of the kidneys and the prevalence of risk factors for cardiovascular complications in OW, taking into account gender differences.Patients and Methods. A cross–sectional single-center study was conducted with the participation of 154 patients (73 men and 81 women) with body mass index (BMI) 25.0–29.9 kg/m2), whose average age was 53.9±12.6 years. Anthropometric and biochemical parameters were evaluated in all patients, the functional state of the kidneys (according to serum creatinine and cystatin C) was studied, and an analysis of cardiovascular risk factors was carried out.Results. Analysis of excretory renal function by cystatin C showed that in most of the examined individuals, regardless of gender, there was a decrease in eGFR to CKD stages 2 and 3a. OW among men was statistically significantly more often associated with hypertriglyceridemia (32.8 %), tachycardia (38.3 %) and atherosclerotic lesion of the carotid arteries (24.6 %). In the subgroup of women with ischemic heart disease, the average age, the content of low-density lipoproteins, the double product index, the frequency of hypercholesterolemia, dyslipidemia and hypertrophy of the left ventricle (LVH), mainly of the eccentric type, were significantly higher, and the hemoglobin content and the number of red blood cells were significantly lower. Significant correlations of eGFR with concentrations of hemoglobin and C-reactive protein, as well as with the value of the left ventricular myocardial mass index (LVMI) were found in men with ischemic heart disease. Correlations of eGFR with the levels of systolic, mean, pulse and central blood pressure, index of functional changes, LDL-C, triglycerides, hemoglobin, fibrinogen, metabolic index, as well as LVMI were found in women with ischemic heart disease. The value of LVH in women was significantly associated with the level of central blood pressure, cystatin C, LDL, hemolobin, fibrinogen, metabolic index, and eGFR. In the general sample of patients with ischemic heart disease, the content of serum cystatin C was positively correlated with LVH and inversely with eGFR calculated by cystatin C. There was a weak negative relationship between the level of central arterial pressure and eGFR by cystatin C.Conclusion. Evaluation of excretory renal function, according to cystatin C and serum creatinine, in individuals with ISM has a higher diagnostic value than evaluation using methods based on the use of serum creatinine alone. In males, the presence of OW is associated with tachycardia, hypertriglyceridemia, a significant decrease in GFR and an increase in the frequency of atherosclerotic changes in the carotid arteries. The following cardiovascular risk factors are associated in women with ischemic heart disease: old age, anemia, increased fibrinogen concentration, dyslipidemia, increased values of the double product index, metabolic index and index of functional changes, as well as hemodynamic and LVH parameters.

Attainment of LDL-Cholesterol Goals in Patients with Previous Myocardial Infarction: A Real-World Cross-Sectional Analysis.

The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.

Systemic immune-inflammation index as a novel hematological marker for predicting the recurrence of deep venous thrombosis.

To determine whether there was a possible predictive relationship between systemic immune-inflammation index (SII) and recurrence of deep venous thrombosis (DVT). A total of 231 patients with DVT who met the study criteria and whose data could be accessed were enrolled to this retrospective single-centered cross-sectional study. Of them 26 patients with DVT recurrence consisted of the study group (Group 1) while remaining 205 cases without recurrence were considered as the control population (Group 2). The patients' basic clinical features and laboratory results from the complete blood count (CBC) test were recorded and compared between groups. Following univariate analyses, a multivariate logistic regression analysis was performed to identify the independent predictors of the recurrence of DVT. Additionally, a receiver-operating characteristic (ROC) curve analysis was performed to detect the cut-off values of the predictors with sensitivity and specificity rates. There were no significant differences between the groups for basic clinical features, except for diabetes mellitus, pulmonary embolism, and atrial fibrillation. Although the univariate analysis revealed that the median values of NLR, PLR, and SII were significantly higher in the DVT recurrence group, only SII was determined to be a significant and independent predictor of DVT recurrence in the multivariate logistic regression analysis. According to ROC curve analysis, SII of 1685 × 103/mm3 constituted the cut-off value for predicting DVT recurrence with 61.5% sensitivity and 76.6% specificity (AUC = 0.686, p = .001). The present study demonstrated for the first time in the literature that SII significantly predicted the recurrence of DVT.

Peg-asparaginase associated toxicities in children with acute lymphoblastic leukemia: A single-center cross-sectional study

BackgroundLeukemia is the most prevalent type of cancer affecting children, representing approximately 35% of cancer diagnoses in Saudi Arabia. Notably, significant improvement in the overall survival and cure rates for pediatrics with acute lymphoblastic leukemia (ALL) has been attributed to adding asparaginase to the chemotherapy regimen. However, the administration of these agents may lead to a multifactorial range of toxicities that often alter treatment outcomes. ObjectiveThe study aimed to characterize the prevalence of common toxicities related to polyethylene glycol (PEG) asparaginase in children aged 0–14 years diagnosed with ALL. Additionally, it assessed the types of toxicities associated with intravenous (IV) and intramuscular (IM) administration of Peg-asparaginase. MethodIt was an observational retrospective cross-sectional study. Data was extracted from the hospital's electronic health record (EPIC). Using EPIC, we reviewed medical charts of all pediatric patients below 14 years old diagnosed with ALL who received at least one dose of PEG-asparaginase between January 2020 and March 2023. The toxicity grading was based on the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE). ResultsOne hundred and ninety-one patients with ALL were included in the study. Overall, 79 toxicity episodes were experienced by the study patients. Anaphylaxis/hypersensitivity (36.7%) and hepatotoxicity (31.6%) were the most prevalent toxicities reported, followed by pancreatitis and hyperglycemia (12.7% each). According to the CTCAE grading, approximately 70% of toxicities were categorized as Grade 3 and 4. Notably, 60% of the events occurred during the induction and consolidation phase of therapy. Interestingly, there was no significant difference in rates of toxicities between patients receiving IV or IM PEG-asparaginase. ConclusionThe distribution of toxicities highlighted in our study aligns with findings from previously published studies. Furthermore, multivariate analysis indicated that patients with high-risk ALL and T-ALL were more likely to develop toxicities compared to other forms of ALL.

Knowledge, attitude, and practice of healthcare providers on chronic refractory cough: A cross-sectional study

ObjectivePrevious studies from outside China showed that the knowledge, attitudes, and practice (KAP) of chronic refractory cough (CRC) was moderate among physicians. This study examined the KAP toward CRC in Chinese healthcare providers. MethodsThis single-center cross-sectional study was conducted at The Sixth Affiliated Hospital of Nantong University, Yancheng Third People's Hospital, from July 2022 to January 2023 and enrolled healthcare providers. The demographic characteristics and KAP scores were collected using a questionnaire (Cronbach's α = 0.934) developed based on CRC guidelines. ResultsThe study included 539 healthcare providers. The mean knowledge score was 8.27 ± 2.37 (maximum of 14, 59.07%), indicating poor knowledge. The highest rates of inaccuracies pertained to knowledge about the definition of chronic cough, empirical treatment methods, and potential risks of different treatments, suggesting a need for unified training in all aspects of CRC for medical staff. The mean attitude score was 49.74 ± 63.63 (maximum of 60, 82.90%), indicating favorable attitudes. Most healthcare providers believed that CRC affects normal work and life and that it would be necessary to provide more help to patients from the perspectives of drug treatment and psychological counseling. The mean practice score was 23.20 ± 6.28 (maximum of 35, 66.29%), indicating poor practice. ConclusionThis study suggests that healthcare providers in Yancheng have poor knowledge, favorable attitudes, and poor practice of CRC. This study provides points that should be targeted in future training and continuing education activities.

Covid-19 vaccination in pregnancy and placental pathology

Objective: To describe and determine the association between Covid-19 vaccination in pregnancy and placental pathology. Methods: Conducted in a tertiary hospital in Medan, Indonesia, from April 30th 2022 to June 30th 2022, this single-center cross-sectional study involved Covid-19 vaccinated and unvaccinated women with singleton full-term pregnancies delivering live fetuses via cesarean section. Maternal characteristics, placental pathologies, and the placental index were documented at enrollment. The association between Covid-19 vaccination status and placental pathology was assessed. Results: The study enrolled 200 pregnant women, including 110 vaccinated women and 90 unvaccinated women. No significant differences were observed in birthweight (P=0.48), placental index (P=0.48), and placental pathology findings [intervillous bleeding (P=0.20), increased syncytial knots (P=0.83), chorangiosis (P=0.13), villous stromal edema (P=0.13), vascular dilation and congestion (P=0.13), and vascular wall thrombus (P=0.71)] between the vaccinated and unvaccinated groups. Conclusions: This study revealed no statistically significant association between Covid-19 vaccination and placental pathology. The findings support the safety of Covid-19 vaccination during pregnancy, in regards to changes of the placental pathology.

Influence of Donor Factors on Descemet Membrane Endothelial Keratoplasty (DMEK) Graft Preparation Outcome.

To determine which donor characteristics, like previous diseases and surgeries, influence the severity of the DM/endothelial lamella preparation prior to DMEK-surgery. Retrospective cross-sectional single-center study is presented. Eight hundred and forty-six eyes with DMEK-surgery between 01/2018 and 01/2021 performed at the University Hospital Cologne, Germany, were included. Information regarding the donors' previous diseases and surgeries were provided by a large database of a cornea bank (Multi Tissue Bank Mecklenburg-Vorpommern) and merged with the Cologne DMEK database, which contains information regarding preparation characteristics of the surgeon-prepared graft directly preoperatively. Three preparation groups (easy, difficult and very difficult) were correlated to the donors' previous diseases and surgeries. The following characteristics were used for the assignment in one of the three groups: stripping difficulty, rolling and staining behavior, central and peripheral adherences, tissue fragility and DM-splitting. Significant risk factors for DM-splitting were diabetes mellitus (DMel) type II, heart failure, chronic kidney disease and previous cataract surgery (p=0.022, p=0.012; p=0.047 and p<0.001 respectively). Previous DMel (especially type 2) was significantly associated with the occurrence of central adherences (p=0.009). Several cardiovascular diseases (p-values between <0.001 and p=0.038), DMel type II, chronic kidney disease and previous cataract-surgery were associated with peripheral adherences (p=0.004; p=0.020 and p<0.001 respectively). Furthermore, pseudophakic donor eyes presented a higher degree of fragility of the graft (p<0.001). Age was a significant risk factor for difficult preparation (p<0.001). The staining of the graft was poorer in donors with chronic kidney disease (p=0.037). Donor diabetes mellitus type 2, heart failure, previous cataract surgery, chronic kidney disease and age are associated with a difficult DMEK graft preparation. For every one-year increment in donor age, the odds of having very difficult preparation were increased by 3%. Also, chronic kidney disease predisposes to a poor tissue staining with trypan blue during preparation.

Comprehensive analysis of vulnerability status and associated affect factors among prehospital emergency patients: a single-center descriptive cross-sectional study.

Prehospital emergency care is a critical but often understudied aspect of healthcare. Patient vulnerability in this setting can significantly impact outcomes. The aim of this study was to investigate the vulnerability status and to determine associated affect factors among prehospital emergency patients in China. In this cross-sectional study conducted in China, from April 2023 to July 2023, we assessed the vulnerability of prehospital emergency patients using the Safety in Prehospital Emergency Care Index (SPECI) scale. We conducted a detailed questionnaire-based survey to gather demographic and disease-related information. We employed the SPECI scale, consisting of two subscales, to evaluate patient vulnerability. Statistical analyses, including t-tests, ANOVA, and multiple linear regression, were used to identify factors associated with vulnerability. The study included a total of 973 prehospital emergency patients, with a response rate of 81.9%. These patients exhibited a low-to-moderate level of vulnerability, with an average SPECI score of 14.46 out of 40. Vulnerability was significantly associated with age (particularly those aged 60 and above), disease severity (severe conditions increased vulnerability), disease type (circulatory diseases correlated with higher vulnerability), alterations in consciousness, and chronic diseases. Unexpectedly, digestive system diseases were negatively correlated with vulnerability. Addressing patient vulnerability in prehospital care is essential. Tailored interventions, EMS provider training, and interdisciplinary collaboration can mitigate vulnerability, especially in older patients and those with severe conditions.

Use of a Handheld Ultrasonographic Device to Identify Heart Failure and Pulmonary Disease in Rural Africa

Agreement in lung ultrasonography findings between clinicians using a handheld ultrasonographic device and expert sonographers using a high-end ultrasonographic machine has not been studied in sub-Saharan Africa. To determine the agreement in ultrasonographic findings and diagnoses between primary care clinicians trained in lung ultrasonography, board-certified expert sonographers, and senior physicians. This cross-sectional single-center study was conducted from February 1, 2022, to April 30, 2023 at a referral center in rural Tanzania. Individuals 5 years or older with respiratory symptoms and at least 2 distinct respiratory signs or symptoms were eligible. A total of 459 individuals were screened. Participants provided their medical history and underwent a clinical examination and lung ultrasonography performed by a clinician, followed by a lung ultrasonography performed by an expert sonographer, and finally chest radiography and a final evaluation performed by a senior physician. Other tests, such as echocardiography and Mycobacterium tuberculosis testing, were conducted on the decision of the physician. Clinicians received 2 hours of instruction and three 2-hour sessions of clinical training in the use of a handheld lung ultrasonographic device; expert sonographers were board-certified. Percentage agreement and Cohen κ coefficient for sonographic findings and diagnoses compared between clinicians and expert sonographers, and between clinicians and senior physicians. The median (IQR) age of 438 included participants was 54 (38-66) years, and 225 (51%) were male. The median (range) percentage agreement of ultrasonographic findings between clinicians and expert sonographers was 93% (71%-99%), with κ ranging from -0.003 to 0.83. Median (range) agreement of diagnoses between clinicians and expert sonographers was 90% (50%-99%), with κ ranging from -0.002 to 0.76. Between clinicians and senior physicians, median (range) agreement of diagnoses was 89% (55%-90%), with κ ranging from -0.008 to 0.76. Between clinicians and senior physicians, diagnosis agreements were 85% (κ, 0.69) for heart failure, 78% (κ, 0.57) for definite or probable tuberculosis, 50% (κ, 0.002) for viral pneumonia, and 56% (κ, 0.06) for bacterial pneumonia. In this cross-sectional study, the agreement of ultrasonographic findings between clinicians and sonographers was mostly substantial. Between clinicians and senior physicians, agreement was substantial in the diagnosis of heart failure, moderate in the diagnosis of tuberculosis, but slight in the diagnosis of pneumonia. These findings suggest that handheld ultrasonographic devices used in addition to clinical examination may support clinicians in diagnosing cardiac and pulmonary diseases in rural sub-Saharan Africa.

Psychological Distress Associated with Enforced Hospital Isolation Due to COVID-19 during the "Flatten the Curve" Phase in Morocco: A Single-Center Cross-Sectional Study.

(1) Background: although much research has highlighted the mental health challenges faced by patients in hospital isolation during the COVID-19 pandemic, data from low-middle-income countries, including Morocco, are lacking. The main objective of this study was to assess the psychological distress of patients undergoing enforced hospital isolation during the initial phase of the COVID-19 pandemic in Morocco. (2) Methods: we conducted a cross-sectional study between 1 April and 1 May 2020, among patients hospitalized in isolation for suspected or confirmed COVID-19 at the Ibn Sina University Hospital of Rabat, Morocco. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). Binary logistic regression was performed to identify variables associated with anxiety and depression, with a cutoff of ≥8 used for both scales to create dichotomous variables. (3) Results: among 200 patients, 42.5% and 43% scored above the cut-off points for anxiety and depression, respectively. Multiple logistic regression identified female gender, a higher education level, a longer duration of isolation, and a poor understanding of the reasons for isolation as significant factors associated with anxiety. Conversely, female gender, chronic disease, a longer duration of isolation, and a poor understanding of the reasons for isolation were factors significantly associated with depression. (4) Conclusions: our study underscores high rates of anxiety and depression among patients forced into hospital isolation during the initial phase of COVID-19 in Morocco. We identified several factors associated with patients experiencing psychological distress that may inform future discussions on mental health and psychiatric crisis management.

Metabolic Dysfunction Associated Liver Disease in Patients Undergoing Coronary Computed Tomography Angiography.

In this single-center cross-sectional study on patients undergoing coronary computed tomography angiography (CCTA), we assessed the prognostic significance of metabolic dysfunction associated steatotic liver disease (MASLD), metabolic syndrome (MetS), and CCTA-derived parameters for predicting major adverse cardiovascular events (MACE). Over a mean follow-up of 26.9 months, 2038 patients were analyzed, with 361 (17.7%) experiencing MACE. MASLD was associated with a higher MACE incidence (25.90% vs. 14.71% without MASLD, p < 0.001). Cox regression revealed significant associations between MASLD, coronary calcium score (CCS), number of plaques (NoP), epicardial fat volume (EFV), and MACE, with hazard ratios of 1.843, 1.001, 1.097, and 1.035, respectively (p < 0.001 for all). A composite risk score integrating CCS, NoP, EFV, and MASLD demonstrated superior predictive value for MACE (AUC = 0.948) compared to individual variables (p < 0.0001 for all). In conclusion, MASLD is linked to an elevated risk of MACE, and a comprehensive risk-scoring system incorporating imaging and clinical factors enhances MACE prediction accuracy.

Factors Associated with Malaria in Pregnancy among Women Attending Fort Portal Regional Referral Hospital in Fort Portal City, Western Uganda

Globally, there was a significant decrease in the number of malaria-risk pregnancies between 2007 and 2020. The risk of Plasmodium falciparum or Plasmodium vivax malaria increased by 25% in Africa compared to 2007. Due to the fast-expanding population and associated rise in pregnancies in malaria-endemic areas, the number of people at risk in Africa has increased despite malaria rates declining in the region. This study determined the prevalence and factors associated with malaria in pregnancy among women attending Fort Portal Regional Referral Hospital. This was a single-center health facility-based cross-sectional study. Data was collected using a face-to-face interview through a structured questionnaire from willing participants. After collecting the data, the principal investigator checked the completed questionnaires for consistency and completeness. Data was coded, cleaned, and entered into the computer using Microsoft Excel, and then analyzed using SPSS version 20. Logistic regression analysis was done to ascertain the relationship between dependent and independent variables. Descriptive statistics were summarized in the form of frequency tables, pie charts, p-values, and odds ratios. A total of 253 pregnant mothers attending ANC were enrolled in this study. The majority (38.3%) of the study participants were aged 30-39 years, attained secondary education (52.2%), earned 100,000–200,000 per month (56.9%), and were housewives (51.0%). In this study, the prevalence of malaria in pregnancy was 10.3%. Age, level of education, income status, and residence, use of an ITN, gravidity, and ANC follow-up were significantly associated with malaria in pregnancy at multivariate logistic regression analysis. Malaria continues to be a major public health issue among pregnant mothers. Age, level of education, income status, and residence, use of an ITN, gravidity, and ANC follow-up were factors significantly associated with malaria in pregnancy.

Comparison of body mass index and fat mass index to classify body composition in adolescents—The EVA4YOU study

The objectives of this study were to develop age- and sex-specific reference percentiles for fat mass index (FMI) and fat-free mass index (FFMI) in adolescents aged 14 to 19 years and to determine differences in overweight/obesity classification by FMI and body mass index (BMI). The EVA4YOU study is a single-center cross-sectional study conducted in western Austria. Cardiovascular risks including anthropometric measurements and bioelectrical impedance analysis were assessed in adolescents (mean age 17 years). FMI and FFMI were calculated as the ratio of fat mass (FM) and fat-free mass (FFM) to the square of height and compared to study population–specific BMI percentiles. One thousand four hundred twenty-two adolescents were included in the analysis. Girls had a significantly higher mean FM and FMI and a significantly lower mean FFM, FFMI (p < 0.001, each), and mean BMI (p = 0.020) than boys. Body composition classification by FMI and BMI percentiles shows a concordance for the < 75th and > 97th percentile, but a significant difference in percentile rank classifications between these two cut-off values (all p < 0.05). Based on FMI, 15.5% (221/1422) of the whole population and 29.4% (92/313) of those between the 75th and 97th percentiles are classified one category higher or lower than those assigned by BMI. Conclusion: Classification of normal or pathologic body composition based on BMI and FMI shows good accordance in the clearly normal or pathologic range. In an intermediate range, FMI reclassifies categories based on BMI in more than a quarter of adolescents. Cut-off values to differentiate normal from pathologic FMI values on a biological basis are needed.Trial registration: The study is registered at www.clinicaltrials.gov (Identifier: NCT04598685; Date of registration: October 22, 2020).What is Known:• Chronic non-communicable diseases (NCDs) are the leading cause of morbidity and mortality globally, with major risk factors including unhealthy diets, harmful behaviors, and obesity. Obesity in children and adolescents is a key risk factor for later NCDs, which is commonly measured by Body Mass Index (BMI).• BMI can be misleading as it doesn't distinguish between fat mass (FM) and fat-free mass (FFM), leading to potential misclassification of obesity in children. Previous studies have already suggested the use of the Fat Mass Index (FMI) and Fat-Free Mass Index (FFMI) as a more accurate measures of body composition.What is New:• This study adds the first age- and sex-specific reference values for FMI and FFMI in Austrian adolescents using bioelectrical impedance analysis (BIA) as a safe and secure measurement method of a large representative cohort.• We found percentile misclassification between BMI and FMI when categorizing for obesity, especially in intermediate categories of body composition. Furthermore, when comparing the new reference values for FMI and FFMI to existing ones from the US, UK, and Germany we could show a good alignment within the European cohorts and major differences with American values, indicating and confirming the difference of FMI and FFMI for different populations of different ethnical background, living on different continents.
