Impact of helminth infections during pregnancy on maternal and newborn Vitamin D and on birth outcomes

Poor birth outcomes in low- and middle income countries are associated with maternal vitamin D deficiency and chronic helminth infections. Here, we investigated whether maternal Schistosoma haematobium affects maternal or cord vitamin D status as well as birth outcomes. In a prospective cross-sectional study of pregnant women conducted in Lambaréné, Gabon, we diagnosed maternal parasitic infections in blood, urine and stool. At delivery we measured vitamin D in maternal and cord blood. S. haematobium, soil-transmitted helminths, and microfilariae were found at prevalences of 30.2%, 13.0%, and 8.8%, respectively. Insufficient vitamin D and calcium levels were found in 28% and 15% of mothers, and in 11.5% and 1.5% of newborns. Mothers with adequate vitamin D had lower risk of low birthweight babies (aOR = 0.11, 95% CI 0.02–0.52, p = 0.01), whilst offspring of primipars had low cord vitamin D levels, and low vitamin D levels increased the risk of maternal inflammation. Maternal filariasis was associated with low calcium levels, but other helminth infections affected neither vitamin D nor calcium levels in either mothers or newborns. Healthy birth outcomes require maintenance of adequate vitamin D and calcium levels. Chronic maternal helminth infections do not disrupt those levels in a semi-rural setting in sub-Saharan Africa.

Normal sonographic measurements for kidney dimensions in Saudi adult population: A cross-sectional prospective study.

The use of ultrasound-based measurements to determine renal size has proven valuable in the diagnosis of renal function and associated disorders. The dimensions of the abdominal organs are affected by an individual's body age, height, sex, and weight. The objective of this study was to establish the standard sonographic parameters for renal dimensions and to determine the correlation between body measurements and renal dimensions in a population of healthy adults residing in Jazan City, Saudi Arabia. The present study was a prospective study conducted at a single center located in Jazan City from February to August 2022. Ninety-five participants underwent abdominal ultrasonography. The process of measuring renal size through sonography entails the measurement of various dimensions of the kidney, such as renal length, width, and thickness. The demographic information of the participants, including their sex, age, height, and weight, was documented. All analyses were performed using Statistical Package for the Social Sciences v27 software. The dimensions of the right kidney, specifically the length, width, and thickness, had mean value of 9.79 centimeters (cm), 5.09 cm, and 4.10 cm, respectively. The left kidney had mean dimensions of 10.1 cm, 5.09 cm, and 4.10 cm for length, width, and thickness, respectively. The left kidney was larger than the right kidney. Furthermore, male participants exhibited larger kidney measurements than their female counterparts did. A noteworthy positive correlation was observed between the thickness of the left kidney and sex, whereas no significant correlations were found with age, weight, or height. The current study revealed that the kidney dimensions were observed to be larger in males as compared to females. The research findings indicate that there is no significant correlation between kidney dimensions and various demographic factors, such as age, height, weight, and sex. In addition, this study provides reference tables for further use.

Association between gallstone disease and carotid intima-media thickness: a prospective observational cross-sectional study in a tertiary care center

Assessment of volume status of pediatric hemodialysis patients.

Accurate volume status assessment and dry weight achievement are the most challenging goals for a nephrologist. We aimed to evaluate the role of ultrasonographic parameters including lung ultrasound and inferior vena cava (IVC) measurements as practical methods of volume status assessment in children on hemodialysis by comparing them with established techniques, such as clinical evaluation and bioimpedance spectroscopy. A prospective cross-sectional study compared pre- and post-dialysis volume status using bioimpedance spectroscopy (BIS) parameters and clinical data with ultrasonographic lung B-lines and IVC parameters in children on regular hemodialysis. A total 60 children (mean age 9.4 ± 2.8years) were enrolled. Twenty patients (33.3%) were clinically overloaded to varying degrees (17 patients had mild to moderate signs of fluid overload and 3 patients had moderate to severe signs of fluid overload). All other patients (66.7%) were clinically euvolemic. Sonographic parameters were significantly lower post-dialysis than pre-dialysis, including lung B-line count and IVC diameter. IVC collapsibility index mean was significantly higher post-dialysis than pre-dialysis. There was a significant correlation between the lung B-line count, IVC parameters, and BIS-measured overhydration both before and after hemodialysis. Nine patients had ≥ 8 B-lines post-dialysis, only three of them were hypertensive. Clinical criteria alone are not specific for determining accurate fluid status in pediatric hemodialysis patients. Lung B-line score, IVC parameters, and BIS may be complementary to each other and to clinical data. Lung B-lines outperform IVC measurements and BIS in subclinical volume overload detection in pediatric hemodialysis patients.

Gut microbiota composition in recurrent acute otitis media: a cross-sectional observational study.

Recurrent acute otitis media (rAOM) poses a significant challenge in children aged 1 to 6 years, characterized by frequent and treatment-resistant ear infections. While existing studies predominantly focus on alterations in the nasopharyngeal microbiome associated with rAOM, our research explores the understudied association with the gut microbiome.In this cross-sectional observational prospective study, we enrolled 35 children aged 1 to 6 years during the 2021/2022 cold season. The test group comprised children with rAOM (n = 16), and the control group consisted of generally healthy children (n = 19). Samples (stool and nasopharyngeal swabs) were collected in late spring to ensure an antibiotic-free period. Detailed metadata was gathered through a questionnaire examining factors potentially influencing microbiota. Microbiota composition was assessed through amplicon sequencing of the V3-V4 region of the 16S rRNA gene. Our findings revealed limited alterations in gut microbiota composition among children with rAOM compared to healthy controls. Six bacterial taxa (Veillonella, Lachnospiraceae, Ruminococcaceae, Lachnospiraceae, Bacteroides and Blautia) were differentially represented with weak statistical significance. However, several bacterial taxa displayed correlations with multiple consecutive infections, with Turicibacter showing the most significant association. Additionally, day care centre attendance emerged as a potent gut microbiota modifier, independent of rAOM. Although our study identified limited differences in gut microbiota composition between children with rAOM and healthy controls, the observed correlations between the number of infections and specific bacterial taxa suggest a potential link between rAOM and the gut microbiota, warranting further investigation.

Prevalence and associated Factors of Anemia in Diabetic Patients

Introduction: Diabetes presents a significant global health challenge due to its association with a range of pathological changes, such as metabolic, cellular, and blood disturbances, that lead to long-term microvascular and macrovascular complications. Healthcare providers often underestimate anemia as a co-morbidity in diabetes, despite the wide range of prevalence estimates reported in the literature. Addressing anemia in diabetes patients early can reduce the incidence of these complications, as has been demonstrated. Aim of the study: The study aimed to estimate the prevalence of anemia and its associated factors among patients with type 2 diabetes mellitus (T2DM). Methods: This is a cross-sectional prospective study with a retrospective review of diabetic patient medical records attending family medicine clinics at four military hospitals (King Hussien Medical Center, Prince Rashed Military Hospital, Queen Aliah Military Hospital, and Prince Hashem Military Hospital) at Royal Medical Services. Adult patients over the age of 18 diagnosed with type 2 diabetes mellitus for more than one year will be included in the study. However, those patients with diseases (such as thalassemia and leukemia) or other systemic disorders (such as infectious diseases) that could result in anemia, those with acute conditions such as acute hemorrhage, those who received blood transfusions in the last three months, pregnant women, or type 1 diabetes will be excluded. Anemia will be defined as hemoglobin level < 13 g/dl in men and 12g/dl in females (Harrison TR, 2011). Type 2 DM will be defined glycated hemoglobin (HbA1c > 6.5%), fasting blood glucose (FBG > 126 mg/dl), random blood glucose (RBG > 200 mg/dl) (American Diabetes Association, 2012). Patients’ medical records will be reviewed for patient medications, duration of diabetes, diabetic complications, and glycemic control. Furthermore, to exclude any patients who have one or more of the aforementioned conditions reported in the exclusion criteria. Meanwhile, researcher will collect the following data in the clinic after patients’ agreement to participate in the study which include: age, sex, marital status, smoking status, comorbidities, anthropometric measurements including weight, height and body mass index (BMI). Moreover, patient will ask to withdraw complete blood count (CBC) blood sample which include hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) for diagnosing anemia if its present. Patients will be divided into two groups based on the presence of anemia; anemic group and non-anemic group. Regarding study variables. Glycemic control will be classified into two categories based on HbA1c result (controlled diabetic group comprised those whose HbA1c level was equal to or <7.5% and poorly controlled diabetic group comprised those whose HbA1c level was >7.5%). Body mass index will classify according to Center of Disease Control (CDC) as follow: BMI score < 18.5 Kg/m2 is underweight, 18.5–24.9 Kg/m2 is normal, 25–29.9 Kg/m2 is overweight and BMI ≥ 30 Kg/m2 is obese. The sample size will be calculated based on Cohran’s sample size formula as: n=Z2 pq /e2. Here, p will be the anticipation of anemia prevalence in the diabetic population, q=1 - p; e is an acceptable error (5%); and Z= 1.96. A simple random sampling (systematic procedure) will be used to choose patients with type 2 diabetes in order to reduce the possibility of selection bias. With this technique, we randomly choose the first subject and then select the next subjects in a periodic manner according to K (interval). K will be determined based on the sampling frame prepared by researchers divided by n. Descriptive analysis will be used with the mean (standard deviation) for normally distributed variables and the median (inter-quartile range) for highly skewed distributions. The t-test and the Mann-Whitney test will be used to compare the baseline characteristics of quantitative variables between anemic and non-anemic groups for variables with a normal and highly skewed distribution, respectively. Categorical variables will be compared between the groups using the chi-square test. Logistic regression analyses will be employed to find out how these variables are associated with anemia. The results will be given as odds ratios (ORs) with a 95% confidence interval (CI). We will select only covariates with a p-value <0.20 in the univariate analysis to enter the logistic analysis.

Role of serum α-Klotho level in patients with breast carcinoma.

e15031 Background: The Klotho gene regulates multiple intracellular signalling pathways involving FGF-23, Insulin, IGF1, TGF-β1, Wnt/β-catenin and mammalian targets of rapamycin. The Klotho gene is downregulated in cancer and has a tumour suppressor role. Only a few studies have been done assessing its role in various cancers. None has looked into its association with all the clinicopathological characteristics of Carcinoma breast along with Pathological complete response (PCR). In August 2022, an oral senolytic form of Klotho was identified making it a possible and targetable protein. Methods: This was a Prospective cross-sectional study. Patients with biopsy-proven carcinoma breast who were previously untreated and had no significant past history were included. 84 patients were studied. Serum αKlotho level was estimated before initiating any treatment and its association with clinicopathological characteristics and with PCR was analysed. Results: A total of 84 patients were studied. The mean age was 50.76 years. Amongst our patients 65% were Estrogen Receptor (ER)+, 41.6% HER2+ and 11.9% were TNBC. 11.9% were of T1 stage, 29.8% T2, 19% T3, and 39.3% were T4. 16.7% had N0, 48.8% N1, 14.3% N2 and 20.2% had N3 stage. 20.2% were metastatic (MBC) and 79.8% were non-metastatic. 33.3% had grade 3 tumours, 56% grade 2 and 10.7% had grade 1. 61.9% were treated with NACT. The mean serum αKlotho level was 1.81ng/ml ranging from 0-5.15ng/ml. The αKlotho level was 2.04ng/ml in ER+ and 1.37ng/ml in ER-negative (p 0.011). As the Nottingham grade of the tumour increased from 1 to 3, αKlotho level decreased, with a mean value of 3.54ng/ml in grade 1, 1.71ng/ml in grade 2, and 1.42ng/ml in grade 3 (p 0.001). As the T stage increased from 1 to 4, αKlotho level decreased from 2.6ng/ml to 1.61ng/ml. Patients with N0 had a higher αKlotho of 2.92ng/ml, N1 had 1.64ng/ml, N2 1.79ng/ml, and N3 had 1.31ng/ml (p 0.001). MBC had a lower level of 1.47ng/ml than non-metastatic(1.9ng/ml). αKlotho level negatively correlated with ki67 with a correlation coefficient of -0.2. Among the patients who received NACT, we analysed 36 patients for the correlation with PCR. αKlotho level in patients who attained PCR was 1.58ng/ml and in those who did not attain PCR was 1.64ng/ml which was not significant. Conclusions: Klotho gene is identified to have a tumour suppressor role and its product αKlotho seems to have a protective role in Carcinoma breast. We found that patients with a higher serum αKlotho level had a lower histological grade(p 0.001) and a Node-negative (p 0.001) disease. Non-metastatic patients and patients with lower Ki 67 had high αKlotho levels. However, we could not find any significant association between αKlotho level and PCR. This is the first study with a large sample size done to look at the association of serum αKlotho with clinicopathological characteristics of carcinoma breast and that has found a significant association of αKlotho levels with higher grade and Node-negative disease.

Association of detrusor wall thickness (DWT) with lower urinary tract symptom severity in benign prostatic hyperplasia: a cross-sectional study

Background and objective: Benign prostatic hyperplasia manifests as lower urinary tract symptoms (LUTS) and prostate gland enlargement, leading to bladder outlet obstruction with consequent structural and functional impacts on the bladder. Urodynamic studies are resource-intensive and invasive. Detrusor wall thickness (DWT) assessment offers a cost-effective, reproducible alternative for evaluating LUTS severity in males with bladder outlet obstruction, utilizing ultrasonographic examination. Methods: This prospective cross-sectional study, conducted at a tertiary care center from May 2023 to January 2024, included 171 patients with LUTS who underwent transabdominal ultrasound for DWT measurements. LUTS severity, assessed using International Prostate Symptom Scores (IPSS) classified participants into mild and moderate-to-severe symptom groups. Pearson’s correlation coefficient assessed the association between DWT and IPSS, and an independent sample t-test compared means, using a significance level of 5% (P-value ≤0.05). Results: This study involved participants aged 65.01±11.55 years with an IPSS score ranging from 1 to 35, with a mean for mild and moderate-to-severe symptom groups were 4±2.12 and 15.93±6.74, respectively. DWT mean of 1.64±0.38 mm for mild, and 2.4±0.43 mm for moderate to severe symptoms. Pearson’s correlation (r=0.697, n=171, P<0.001) indicated a strong DWT-LUTS correlation and a significant DWT mean difference between mild and moderate-to-severe symptom groups was found via an independent t-test (P<0.001, 95% CI: −0.8970 to −0.6414). Conclusion: The study establishes the value of transabdominal ultrasound-detected DWT as a cost-effective, noninvasive, and reproducible tool for assessing LUTS severity in males with benign prostatic hyperplasia.

Maximum surgical blood ordering schedule for elective surgical procedures in Omdurman teaching hospital, Sudan

BackgroundThe need for blood during a surgical procedure is greater than what blood banks are able to provide. There is an excessive amount of blood being ordered for elective surgeries, surpassing the actual requirements. Only 30% of the cross matched blood is actually used in these surgeries. The accuracy of estimating the transfusion needs before a surgical procedure can be determined by looking at the cross match to transfusion ratio and the transfusion index. “These indicators play a crucial role in developing the maximum surgical blood ordering schedule; in this study, these indicators were tested.”Aim of studyIs to determine the efficiency of blood ordering and transfusion practices for patients undergoing elective surgeries.MethodsThis study is a prospective cross-sectional hospital-based study done at Omdurman Teaching Hospital-Sudan. Conducted for the duration of 6 months period from July to December 2019.The study participants were patients who underwent elective surgical procedures in general surgery and Urology departments as total coverage sample over a period of study duration. Ethical clearance obtained from ethical committee of Sudan Medical Specialization Board.ResultsTwo hundreds seven patients included in this study, the amount of blood units requested were 443-unit, cross matching for 98.6% (n 437) of units were done. Only 100 unit were Transfused (22,8%). The calculated CT ratio was 4.4, transfusion index was 1.6 and transfusion probability was 29.9%.ConclusionTransfusion probability and transfusion index of the present study were optimal but comparatively higher than the standard guidelines as most of the cross matched blood was not utilized.

Unraveling the Mind-Gut Connection: Investigating Anxiety and Depression in Functional Dyspepsia

Psychological association with functional dyspepsia underscores the importance of a holistic approach to its management, addressing both physical and psychological aspects of the condition. Objective: To determine the relationship of anxiety and depression with severity of dyspepsia. Methods: A prospective cross sectional study was carried out in the Endoscopy Unit, Department of Gastroenterology, Baqai Medical Institute. All patients fulfilling the Rome III criteria for functional dyspepsia with normal endoscopy findings were included in the study, Pregnant females, patients with known diabetes, chronic kidney disease, chronic liver disease and known psychiatric illness, history of peptic ulcer disease and use of NSAIDs, steroids or alternative medicine were excluded. Severity of dyspepsia was assessed by Short Form Leeds Dyspepsia Questionnaire (SF-LDQ). Whereas hospital anxiety and depression scale (HADS) was used to assess the psychological factors. Results: A total of 223 participants were included in the study. Out of 223 participants, majority 55.6% (124) had moderate dyspepsia, followed by severe dyspepsia 26.9% (60), mild dyspepsia 12.6% (28) and very mild dyspepsia 4.9% (11). Using Hospital Anxiety And Depression Scale (HAD-S), we found that out of 223 participants, 56.5% (126) had moderate to severe anxiety and depression while 29.1% (65) had mild anxiety and depression. Conclusions: It was concluded that functional dyspepsia is clearly associated with common psychological disorders like depression and anxiety. Early recognition and timely linkage to care in such cases can considerably improve the health-related quality of life and hence decrease the global burden of this common disorder.

Alice in Wonderland Syndrome (AIWS): prevalence and characteristics in adults with migraine.

Alice in Wonderland Syndrome (AIWS) is a sensory disorder characterized by a distorted somatosensory and/or visual perception. Additionally, distortion of time perception and symptoms of derealization/depersonalization may occur. AIWS is frequently associated with migraine. However, its prevalence, and clinical characteristics remain poorly understood. Here, we investigated the prevalence and features of AIWS in individuals with migraine. We hypothesized AIWS is more frequent in migraine patients with aura than in those without aura. This was a prospective cross-sectional cohort study, conducted at a tertiary headache center. Participants with migraine filled out questionnaires, providing details on demographics, headache, AIWS characteristics and the occurrence of transient visual phenomena such as fragmented vision. Of 808 migraine patients, 133 individuals (16.5%, mean age 44.4 ± 13.3years, 87% women) reported AIWS symptoms throughout their lives. Micro- and/or telopsia (72.9%) were most frequent, followed by micro- and/or macrosomatognosia (49.6%), and macro- and/or pelopsia (38.3%), lasting on average half an hour. AIWS symptoms occurred in association with headache in 65.1% of individuals, and 53.7% had their first AIWS episode at the age of 18years or earlier. Migraine patients with aura were more likely to report AIWS symptoms than those without aura (19.5% vs. 14.1%, p = 0.04). Participants with AIWS reported a higher incidence of 17 out of the 22 investigated visual phenomena. AIWS symptoms appear to be a common lifetime phenomenon in migraine patients. The correlation and clinical parallels between AIWS and migraine aura could indicate shared underlying pathomechanisms.

Prevalence and Impact of Psychiatric Co-Morbidity in Patients with Spinal Pathology in Basrah, Iraq

Background and objective: to minimize complications by proper selection of patients for surgery and to evaluate what is the impact of psychiatric co-morbidity in patients admitted to a spinal surgical unit in Basrah, Iraq. Patients and Methods: A multi-center cross-sectional prospective cohort study was conducted on 247 patients. In Basrah province. During admission complete history was taken in form of identity, complaint, past medical and surgical history, drug history, type of previous and the coming surgery and lastly special emphasis on the questioner to assess patient psychological status using the Patient Health Questioner. Somatic Anxiety Depressive Symptoms (PHQ.SADS) After one week and one-month the same questions were addressed to the patient to check the general condition,and any complications or readmission. Results: Out of the 247 patients: Eight patients refuse to be part of this study, thirty-one patients lost follow up, three patients excluded from the study due to exclusion criteria, five patients their surgery postponded because they were psychologically unstable and advised for psychiatrist consultation. 111 patients (55.5%) of the sample size were male patients. A 90 (45%) patients were at age of 38-57 years, 111 (55.5%) of the sample were male 82 patients (41%) were of moderate degree using the PHQ.SADS. 62 patients (31%) were within the severe scale PHQ.SADS.132 patients (66%) complained from radiculopathy with or without backache,192 (96%) patients discharged safely postoperatively. 41(39.4%) patients were diagnosed with lumber canal stenosis belongs to the severe group. Psychological break down occurs in 10 (5%) patients, 9 (90%) of those patients belong to severe grade category of PHQ.SADS. Conclusion: There was a strong association between pre-operative psychological conditions and post-operative complications in form of repeated visit after surgery and persistence of pain and disability.

Variation in the Branches of Arch of Aorta in Patients Undergoing Contrast Enhanced Multidetector Computed Tomography in a Tertiary Centre, Nepal

Introduction: Variations in the branching pattern of the Arch of Aorta (AoA) are common in patients undergoing contrast-enhanced Multidetector Computed Tomography, the identification of which is crucial in managing patients undergoing cardiovascular/neck surgeries and interventions.Methods: This prospective cross-sectional study involved 513 patients who were sent to the Department of Radiology for evaluation of various pathologies of chest and neck between August 2018 and July 2019. After approval from the Institutional Review Committee {Reference No: 11(6-11) E2/075/076}, contrast-enhanced computed tomography images were evaluated with variations in branches of the left-sided arch of the aorta and symptoms associated.Results: Variations in branches of the arch of aorta were seen in 69 (13.45%; 95% CI: 10.60%-16.71%) of cases, left common carotid artery and brachiocephalic trunk having common origin or common trunk was 51(9.94%). The mean age was 52.4±20 years (Range 3 months to 92 years) with male to female ratio of 1.3:1.Conclusions: Contrast-enhanced computed tomography is the modality of choice for the detection of the variations in branches of AoA, recognition of which is crucial in vascular intervention and surgical procedures to reduce the postoperative morbidity and mortality of the patients.

Step type is associated with loading and ankle motion in tap dance.

Tap dance generates forces and joint motions that can lead to injury; however, little is known about the magnitude of load across different tap steps. The purpose of this study was to calculate peak vertical forces, average vertical foot velocities, and maximum/minimum ankle angles produced by tap dancers with different levels of experience performing the toe cannon, heel cannon, flap, and cramp roll. This prospective cross-sectional study included 14 female tap dancers aged ≥18 years with varying tap experience. Participants were recorded by three cameras while performing a choreographed tap combination containing four steps of interest on a force platform. Adjusting for experience and dancer-level clustering, we identified the steps-cramp roll and toe cannon-that had the highest peak vertical ground reaction force, angles, and velocities compared to flap and heel cannon. There was no effect of experience. The results supported our hypothesis and provide new insights into step production. Over time, the larger forces associated with these steps could pose an increased risk of injury to bones and joints when compared to smaller forces, which may suggest the importance of adjusting routines to reduce or avoid injury.

The Post-COVID-19 Haul on Pulmonary Function: A Prospective Cross-Sectional Study.

Long COVID syndrome, characterized by symptoms like dyspnea, fatigue, and cough, persisting for weeks to months after the initial SARS-CoV-2 infection, poses significant challenges globally. Studies suggest a potential higher risk among females aged 40-50, with symptoms affecting individuals regardless of initial COVID-19 severity, underscoring the need for comprehensive understanding and management. A prospective longitudinal study was conducted at a teaching tertiary care institute in Central India, involving COVID-19 patients from May 2020 to September 2021. Participants, aged 18 or older, diagnosed with COVID-19 and surviving until the last follow-up, were monitored telephonically and during outpatient visits for treatment details and outcomes. Data analysis was done using R software 4.2.1. The baseline characteristics of the study participants showed a majority of moderate COVID-19 severity (47.5%), with a higher proportion of males (64.8%) affected. Common comorbidities included diabetes (27.1%) and hypertension (22.9%). Long COVID-19 symptoms, notably breathlessness, were prevalent, with females exhibiting a significantly higher association. Pulmonary function abnormalities were associated with both long COVID-19 symptoms and higher COVID-19 severity categories, indicating lasting respiratory impact post-infection. Long after the pandemic, COVID-19 continues to raise concerns due to persistent sequelae, with a majority experiencing long COVID symptoms, particularly those with severe initial illness, including breathlessness and abnormal lung function, highlighting prevalent restrictive lung pattern changes.

Magnitude and associated factors of intra operative hypothermia among pediatric patients undergoing elective surgery atXX Comprehensive Specialized Hospital 2023: prospective observational cross sectional study Tigray, Ethiopia

Background: Hypothermia is characterized by a drop in core body temperature of less than 36 °C. It occurs frequently throughout the operating period and affects surgical patient outcomes differently in terms of morbidity and mortality. Because of coagulopathy, metabolic acidosis, multiple organ failure, hemodynamic instability, and infections, a core temperature below 34 °C is strongly associated with mortality. Objective: This study aimed to assess the magnitude and associated factors of intra-operative hypothermia in pediatric patients undergoing elective surgery at the Ayder Comprehensive Specialized Hospital. Method: A prospective observational cross-sectional study was conducted on 399 pediatric patients undergoing elective surgery at Ayder Comprehensive Specialized Hospital in Tigray, Ethiopia, from May 1, 2023, to July 30, 2023. Participants in the study were selected by a systematic random sampling technique. The data collection procedure was chart review and intra-operative temperature measurement, and the collected data were analyzed by SPSS version 23. The independent variables were analyzed using binary and multi-logistic regression. The odds ratio, 95% confidence interval, and p-value of <0.05 were considered statistical significance. Result: The magnitude of intra-operative hypothermia was 52.9%. Neonate and infant [AOR: 6, 95% CI: 3.7, 9.8], (AOR=4.5, 95% CI: 2.9, 7) respectively, volume of fluid administered greater than half liter [AOR: 4.37, (95% CI, 3, 6.4)], patients who underwent surgery during the morning [AOR: 5.3, (95% CI: 3.8, 7.4)], and duration of surgery and anesthesia greater than 120 minutes [AOR: 2.7, (95% CI, 1.8, 4)] and (AOR=3.4, 95% CI, 2.4, 4.9], respectively, were factors significantly associated with intra-operative hypothermia. Conclusion and Recommendation: This study revealed a high magnitude of intraoperative hypothermia among pediatric patients. Being neonates and infants, having a cold volume of IV fluid administered greater than half a liter, entering surgery during the morning, the duration of surgery, and the anesthesia time were significantly associated with intra-operative hypothermia. We would like to advise anesthetists to use warm intravenous fluids, calculate IV fluids, and maintain room temperature.

Assessment of mild cognitive dysfunction in patients with atrial fibrillation utilizing the R4Alz assessment test

Abstract Background/Introduction The association between atrial fibrillation and cognitive dysfunction has accumulated a growing body of evidence in recent years. However, establishing such a diagnosis remains challenging, especially in mild oligosymptomatic patients. REMEDES for Alzheimer (R4Alz) is a novel test, designed to assess cognitive control decline at an early stage. Purpose We sought to evaluate the prevalence of early, mild cognitive dysfunction in patients with paroxysmal atrial fibrillation with the use of established and novel diagnostic tools. Methods This is a prospective cross-sectional study that enrolled consecutive patients with history of paroxysmal atrial fibrillation and matched healthy controls, from a tertiary cardiology department. Patients with history of stroke or known cognitive dysfunction of any type were excluded from the study. Demographic and clinical data were collected. All study participants were subjected to Montreal Cognitive Assessment (MoCA) and to R4Alz within the same day. Cognitive function and attention ability is assessed at three stages with R4Alz: working memory updating (R1), supervisory attention system (R2) and task/rule switching and control of inhibition (R3). The primary endpoint was the difference in cognitive function between patients with atrial fibrillation and controls. Secondary endpoints included the correlation between the two assessment tests in both groups. Statistical analysis was performed with R version 4.1.0 and a p-value<0.05 was considered statistically significant. Results Fifty-five patients with atrial fibrillation and thirty-four controls were enrolled in the study (Mean age: 62.6 y, Female gender: 62.9%). MoCA scores (25.4 ± 4.11 for patients with atrial fibrillation vs 22.3 ± 3.72 for healthy controls, p-value <0.001) (Figure 1) as well as scores of all stages of R4ALz {working memory (R1a, R1b, R1c), supervisory attention system (R2) and task/rule switching – inhibition control (R3a1, R3a2, R3b)} were indicative of mild cognitive dysfunction in patients with atrial fibrillation. The control group exhibited significantly better cognitive performance on all assessment tools (Table 1).Figure 1Table 1

Seasonal differences in physical activity, sedentary behaviour, and sleep patterns in people with type 1 diabetes in Kuwait

AimsThe main aim of the current study was to measure physical activity, sedentary behaviors and sleep levels across the different seasons in people with type 1 diabetes in Kuwait. MethodsA prospective cross-sectional study was conducted from August 2021 to September 2022. Physical activity and sleep metrics were measured over a 7-day period with a wrist-worn accelerometer (GENEActiv). Overall physical activity was measured as a Euclidean Norm Minus One in milli gravitational units (mg). Accelerometer metrics were compared across the seasons and between the sex. ResultsA total of 784 people with type 1 diabetes participated. Mean daily physical activity was 25.2 mg (SD = 7.3). Seasonal differences were seen in overall physical activity (p = 0.05), inactivity (p = 0.04), light activity (p = 0.001), the intensity gradient (p = 0.001) and sleep efficiency (p = 0.02). Poorer metrics were generally seen in Spring and Summer. Overall physical activity, moderate and vigorous physical activity, and inactivity were significantly higher in males compared to females (p ≤ 0.02). Females had a longer sleeping duration (p = 0.02), and higher sleep efficiency (p = 0.04) and light physical activity (p = 0.01). Overall physical activity and the intensity gradient were negatively associated with HbA1c (both p = 0.01). ConclusionsPhysical activity levels were generally low and sleep poor in people with type 1 diabetes in Kuwait and these varied by sex and season. The current data are useful to target and develop interventions to improve physical activity and glycemic control.

#2061 Perirenal fat thickness as a potential marker for cardiovascular risk in chronic kidney disease: the influence of vitamin D analogs

Abstract Background and Aims Patients with CKD show high cardiovascular complication rates. There are classical cardiovascular risk factors, such as obesity, dyslipidemia, and diabetes; however, other cardiovascular disease risk factors are associated with mineral metabolism disorders (phosphorus, hyperparathyroidism, etc.) typically appear in CKD. Due to their pleiotropic effects, vitamin D analogs, such as cholecalciferol, calcitriol, or paricalcitol, have proven effective in controlling bone mineral disease secondary to CKD and cardiovascular pathologies. On the other hand, visceral adiposity has been shown as a risk factor in the general population and in patients with CKD. Specifically, the fat deposited in regions such as the epicardium generates a complex autocrine and paracrine hormonal mechanism that has been associated with cardiovascular complications. Although it has not been widely evaluated, the adipose tissue surrounding the kidneys (perirenal fat [PRF]) could provide additional information of interest in the CKD population. The aim of the study is to assess the relationship between cardiovascular disease, PRF, and the effect of therapeutic interventions for bone and mineral metabolism in patients with CKD. Method This prospective observational and cross-sectional study was designed to evaluate the usage of vitamin D analogs in patients with CKD, focusing on cardiovascular history and PRF accumulation. All the patients were evaluated at the outpatient clinic in Consuelo Hospital in Valencia Spain (January-November 2022). Eighty-three patients with different grades of CKD (G1A1 to G5A3 not on dialysis) were included and follow-up for 24 months. All the patient's data from electronic medical and analytical records were entered into a protocol sheet. The patients that meet the inclusion criteria (eGFR ≤90 or>15 ml/min/1.73 m2; age ≥18 years at the time of signing informed consent, and a life expectancy higher than 1 year) were eligible to participate in the study. As exclusion criteria, patients with an active inflammatory process such as infection, active cancer, or other inflammatory states were excluded beyond those mentioned in inclusion. Patients with an AKI, ADPKD, or CKD requiring RRT were also excluded. Patients were discriminated according to their history of cardiovascular disease (coronary artery disease, stroke, and peripheral vascular disease) and the use of Vitamin D analogs (Cholecalciferol, Calcitriol, and Paricalcitol). The thickness of the PRF was measured in centimeters (cm) through a B-mode ultrasound with a 3.5-MHz convex transductor (Alpinion®; Alpinion Medical Systems, Korea). Patients underwent a bilateral renal ultrasound, and the kidneys were measured anteroposteriorly, transversally, and longitudinally. PRF was measured in the distal third between the cortex and the hepatic border and/or spleen. Results The mean age of the patients was 58.3 ± 16 years. Patients with a cardiovascular disease history showed significantly higher levels of urea (62.0 vs 45.2 mg/dl, p < 0.05), uric acid (5.5 vs 4.3 mg/dl; p < 0.03), intact parathyroid hormone (iPTH) (186.2 vs 65.2 pcg/dl; p0.05) and decreased eGFR (53.55 vs 89.00 ml/min/1.73 mts2). The mean PRF thickness (0.99 vs 0.80 cm; SD ± 0.30; p0.05) was also observed to be elevated with respect to the group who had no previous cardiovascular events (Fig. 1). Moreover, this group showers higher levels (1.2 vs 7.1; p < 0.005) of CRP. Those patients on oral treatment with Paricalcitol (1 mcg/day) had lesser PRF accumulation than those treated with Cholecalciferol (1000 IU/day) or Calcitriol (0.5 mcg/day) (p < 0.05) (Fig. 2). It was not adjusted for confounding factors such as weight, height, or BMI. Conclusion These results show a close relationship between the presence of cardiovascular disease history and a higher accumulation of PRF. The mechanisms by which paricalcitol could influence the decrease in PRF are so far unknown, however, some studies have shown an association between PTH elevation and obesity. Finally, achieving a decrease in the latter could reduce visceral adipose tissue, thus reducing the cardiovascular risk in CKD-affected patients.

#2933 Quality of care in patients after kidney transplantation with or without telemedicine

Abstract Background and Aims Patients after transplantation require special attention to avoid complications. This includes trained medical doctors but also adherent patients and the integration of other health provider. eHealth products have the potential to improve medical care further. Therefore, we established a telemedicine module in addition to the standard care, which is ongoing since 2019. Patients receive a smartphone app to provide vital signs, confirm the intake of medication and have access to their laboratory values, current medication plan and a medication alert. A telemedicine team values the incoming data and acts if needed (www.maccs-projekt.de). In this study, we want to evaluate how satisfied patients are with telemedicine compared to patients receiving standard care only. Method This is a monocentric and prospective cross-sectional study including a set of questionnaires. We have a positive decision of ethics committee at our center. The study started 2020 and is still ongoing. We ask patients with appointments at our center for participation. If a signed consent is available, patients receive a set of questionnaires. We choose the ZAPA (https://www.kbv.de/media/sp/ZAP_Fragebogen_Englisch.pdf) and ZUF-8 (https://gfqg.de/forschung/assessment/zuf-8), both validated questionnaires, to evaluate the quality of care. Results Demographic data: To date 247 patients participate, 156 (63.2%) with additional telemedicine and 91 (36.8%) as control (68% male). Median age is 57 years (±13.59 years). The youngest participant in the study is 21 years old, and the oldest is 85 years old, resulting in an age range of 64 years. In this population, the data indicate the following primary causes for transplantation: IgA Nephropathy (18.1%), ADPKD/Polycystic Kidney Disease (16.5%), unknown aetiology (8.6%), Chronic Glomerulonephritis (6.6%), and Focal Segmental Glomerulosclerosis (4.1%). Collectively, these conditions account for 53.9% of the underlying diseases leading to transplantation in this cohort. All patients are kidney recipients, 24 patients (9.7%) received a second kidney transplant, while only three patients (1.2%) received three kidneys. Nine patients (3.6%) had a mono pancreas transplantation, three patients (1.2%) received two pancreas and one patient (4%) had three pancreas transplantations. Two patients (8%) received a liver transplantation. The median after kidney transplantation is eleven years (± 9.4 years). The maximum of a functioning kidney is currently 39 years. Questionnaires: The ZAP evaluates the satisfaction of patients with their outpatient care centers. The questionnaire has five categories measuring various aspects of medical care (scale 0 to 100 points, higher values indicate greater satisfaction). The results are shown in Table 1. In average 94.7 to 96.8% of patients participated on this test. The questionnaire ZUF-8 evaluates the satisfaction of patients with the current care (every kind of care can be estimated). ZUF-8 includes eight questions and has a range of eight to 32 points. Higher sums indicate better satisfaction. The telemedicine group had a mean of 28.6 points (±3.2 points) and the control group a mean of 28.8 points (±3.4 points). Conclusion All over, patients are highly satisfied with the standard care after transplantation at our center. Patients with access to telemedicine seem to benefit from help regarding organization of their treatment plan. The data indicate trend to better doctor-patient interaction and cooperation of the doctor to support patients, although testing for significance could not rule out the null hypothesis. As the trial is still ongoing, we plan further evaluations with more participants.
