Can CONUT and PNI Scores Predict Necrotizing Pancreatitis in Acute Pancreatitis Patients Presenting to the Emergency Department?

Background and Objectives: Acute pancreatitis, characterized by pancreatic inflammation, poses significant morbidity and mortality worldwide, with varied etiologies including gallstones, alcohol, and certain medications. Necrotizing pancreatitis represents a severe form of parenchymal damage with considerable impact on patient quality of life. Early identification of necrotizing pancreatitis is crucial for timely intervention and improved outcomes. The aim of this study was to investigate the usability of CONUT and PNI scores as prognostic indicators. Materials and Methods: We conducted a retrospective observational study involving patients presenting to the emergency department with acute pancreatitis between January 2020 and October 2023. The Controlling Nutritional Status (CONUT) score and Prognostic Nutrition Index (PNI) were calculated from serum biomarkers to assess nutritional status. Patients were categorized into necrotizing and nonnecrotizing pancreatitis groups, and the utility of CONUT and PNI scores in predicting necrotizing pancreatitis was evaluated. Results: A total of 339 patients were included, with 8.26% diagnosed with necrotizing pancreatitis. CONUT and PNI scores significantly differed between necrotizing and nonnecrotizing groups, with higher CONUT scores and lower PNI scores observed in the necrotizing group. Receiver operating characteristic (ROC) curve analysis revealed significant predictive value of CONUT and PNI scores for necrotizing pancreatitis, with cutoff values of >5 and ≤34, respectively. Conclusions: CONUT and PNI scores demonstrate promise in predicting necrotizing pancreatitis in patients admitted to the emergency department with acute pancreatitis. Additionally, these scores may serve as prognostic indicators for mortality in acute pancreatitis patients. Early identification using CONUT and PNI scores could facilitate timely intervention, potentially reducing mortality and morbidity in this patient population.

Is It Possible to Detect Return of Spontaneous Circulation during Chest Compression? Evaluation of a Novel Method: Carotid Artery Compression Ultrasound.

Objectives: To evaluate the diagnostic accuracy of carotid artery compression using a point-of-care ultrasound probe (POCUS-CAC) in reducing pulse check times and facilitating the detection of the return of spontaneous circulation (ROSC) during cardiopulmonary resuscitation (CPR) compared to manual palpation (MP). The secondary aim of the study is to assess the ability of POCUS-CAC to detect ROSC during ongoing chest compressions. Methods: This prospective study was conducted in a tertiary emergency department between January and June 2023. During CPR, POCUS-CAC was performed by placing a linear ultrasound probe transversely on the lateral neck to assess the compressibility of the carotid artery. Complete compression of the artery without any visible pulsation indicated no ROSC, while resistance to compression or partial compression suggested the presence of ROSC. Simultaneously, another clinician performed manual palpation of the femoral artery. The primary outcome assessed in this study was comparing ROSC detection between POCUS-CAC and traditional methods, and the secondary outcome was comparing the time taken to detect ROSC with each method, and the ability to detect ROSC during ongoing chest compressions. Results: The study included 41 cardiac arrest patients and analyzed 496 MP pulse and 1984 POCUS-CAC checks. The mean time to identify a pulse using POCUS-CAC was significantly shorter, at 2.3 (0.5-7.8, SD ± 1.2, 95% CI [2.25, 2.35]) s, compared to 4.7 (2.0-10.5, SD ± 1.8, 95% CI [4.54, 4.86]) s with MP (p = 0.004). Additionally, 52.9% of ROSC cases were detected earlier using POCUS-CAC, even during ongoing chest compressions. The sensitivity of POCUS-CAC was 100% (95% CI [80.5-100%]) and the specificity was 87.5% (95% CI [67.6-97.3%]). The POCUS-CAC method required less than 5 s in 99.996% of cases. Conclusions: POCUS-CAC significantly reduces pulse check times and enhances the early detection of ROSC during CPR, offering a reliable and rapid alternative to traditional manual palpation methods in emergency settings.

The prognostic role of survivin expression in breast cancer: A systematic review and meta-analysis.

BACKGROUND: Breast cancer is a heterogeneous condition with variations in histopathological, genomic, and biological characteristics. Although clinicopathological prognostic factors and gene expression profiles are commonly used to guide treatment decisions in patients with breast cancer, there is still a need for new prognostic markers. One potential marker is survivin, a protein belonging to the apoptosis inhibitor family. However, studies examining the relationship between survivin and prognosis in breast cancer have yielded inconsistent results. This study aimed to evaluate the impact of survivin expression on the prognosis of breast cancer patients through a meta-analysis. METHODS: Studies evaluating survivin expression were sourced from the PubMed, Embase, and Cochrane databases. We conducted a meta-analysis based on full-text articles that evaluated the relationship between survivin expression and survival by immunochemistry or polymerase chain reaction. The studies were initially divided into 2 groups based on the evaluation of overall survival (OS) and disease-free survival (DFS). Subsequently, each group was further categorized according to the method used to detect survivin expression. Statistical analyses for this study were conducted using Stata and JAMOVI. RESULTS: After screening with keywords, we identified 24 retrospective studies evaluating OS and 15 retrospective studies evaluating DFS, which were included in the analysis. We found that the studies in the meta-analysis were not heterogeneous, and this remained consistent when categorizing the groups by survivin expression detection. Survivin expression was associated with OS (HR 1.23, 95% CI 0.81-1.65) and DFS (HR 0.89, CI 0.42-1.36), indicating poor prognosis. This significant relationship between survivin expression and survival persisted when the studies were categorized by the detection method, either immunohistochemistry or polymerase chain reaction. CONCLUSION: In this study, we evaluated the prognostic significance of survivin expression in patients with breast cancer through a meta-analysis. These results support the use of survivin expression as a prognostic marker in breast cancer, potentially guiding treatment decisions.

Demonstration of the Protective Effect of Vinpocetine in Diabetic Cardiomyopathy.

Background: Diabetic cardiomyopathy (DCM) poses a significant risk for heart failure in individuals with diabetes, yet its underlying mechanisms remain incompletely understood. Elevated blood sugar levels initiate harmful processes, including apoptosis, collagen accumulation, and fibrosis in the heart. Vinpocetine, a derivative of Vinca minor L., has demonstrated diverse pharmacological effects, including vasodilation, anti-inflammatory properties, and enhanced cellular metabolism. This study aims to investigate Vinpocetine's protective and remodeling effects in diabetic cardiomyopathy by evaluating biochemical and histopathological parameters. Methods: Twenty-one adult male Wistar rats were induced with diabetes using streptozocin and divided into Diabetes and Diabetes + Vinpocetine groups. Histopathological analyses, TGF-ß1 immunoexpression, and measurements of plasma markers (TGF-ß, pro-BNP, Troponin T) were performed. Biochemical analyses included HIF-1 alpha and neuregulin-1ß quantification and evaluation of lipid peroxidation. Results: Vinpocetine significantly reduced cardiac muscle thickness, TGF-ß1 expression, and plasma in diabetic rats. HIF-1 alpha and neuregulin-1ß levels increased with Vinpocetine treatment. Histopathological observations confirmed reduced fibrosis and structural abnormalities in Vinpocetine-treated hearts. Conclusions: This study provides comprehensive evidence supporting the protective effects of Vinpocetine against diabetic cardiomyopathy. Vinpocetine treatment improved cardiac morphology, immunohistochemistry, and modulation of biochemical markers, suggesting its potential as a therapeutic intervention to attenuate the negative impact of diabetes on heart function.

Effect of strategies to increase progesterone levels on fertility of bovine embryo transfer recipients - A meta-analysis.

The pregnancy rate following embryo transfer (ET) is a very important factor in the success of embryo production programs. Different strategies were therefore developed to increase pregnancy rates. The aim of this meta-analysis was to investigate the effects of hormone treatments used to increase the success of embryo transfer programs on pregnancy rates. A meta-analysis was performed of 46 trials from 39 publications involving treated (n = 7856) and control (n = 6663) cattle. The meta-analysis explained the effect size with its 95 % confidence interval (CI) for pregnancy per embryo transfer (P/ET) after hormonal treatment under different moderators. Hormonal support was found to increase P/ET compared to the control group (P < 0.05). However, GnRH treatment was found to increase P/ET by approximately 4.3 % and hCG treatment by 8.0 %. Progesterone supplementation was not found to have a statistically significant effect on P/ET. In addition, GnRH treatment significantly increased P/ET when used to transfer in vitro or frozen-thawed embryos or in studies using cows as recipients. It was observed that hCG treatment had a positive effect on P/ET according to all moderators. Progesterone supplementation significantly increased P/ET when frozen embryos were transferred and reduced P/ET, especially in publications where fresh or in vitro produced embryos were transferred or cows were used as recipients. The results of this meta-analysis showed that the use of GnRH, and hCG, in bovine embryo transfer programs increased P/ET, whereas the use of progesterone had no effect on P/ET. However, it was found that P/ET could increase/decrease depending on the moderator.

The Validity and Reliability of the Turkish Version of the Disablement in the Physically Active Scale.

CONTEXT: The Disablement in the Physically Active Scale (DPAS) was recently developed to evaluate the disability process and health-related quality of life. The aim of this study was to investigate the validity and reliability of the Turkish version of the DPAS in physically active individuals with musculoskeletal injury. METHODS: The study sample comprised 64 physically active individuals with musculoskeletal injury aged 16-40 years. The DPAS was translated into Turkish according to the guidelines for cross-cultural adaptation. Short Form-36 was used concurrently to test the construct validity. The test-retest reliability of the Turkish version of the scale assessed by intraclass correlation coefficient and Cronbach α was calculated for internal consistency. RESULTS: Confirmatory factor analysis carried out on the Turkish version of the DPAS was confirmed. Cronbach α was calculated to be .946. The intraclass correlation coefficients ranged between .593 and .924 (P < .001). The Turkish version of the scale showed significant correlations with domains of the Short Form-36 (P < .05). When the sensitivity of the study was evaluated, the highest correlation was found between DPAS total score and impairments (r = .906, P = .001), and the lowest correlation was  between DPAS total score and quality of life (r = .637, P = .001). CONCLUSION: The Turkish version of the DPAS is a reliable, valid, and practical tool. The Turkish version of the DPAS can be used by health professionals to understand quality of life, the disability process, and activity limitations in Turkish-speaking physically active people after musculoskeletal injuries.

Does using microfluidic sperm sorting chips in bovine IVEP affect blastocyst development?

This study aimed to determine the effect of microfluidic sperm sorting chip on embryo development and quality in the sperm treatment step in in vitro embryo production in cattle. Only A-quality oocytes obtained from the ovaries of Holstein cattle were included in the study. These oocytes were first placed in in vitro maturation medium, and matured oocytes were randomly divided into two groups at the 24th hour of maturation. Oocytes in the first group with the Microfluidic Sperm Sorting Chip (MFSC, n = 154) were put into a fertilization medium with spermatozoa prepared with microfluidic sperm sorting device. Oocytes in the second group (Con, n = 169) were fertilized with spermatozoa prepared by the routine sperm treatment step of the commercial company. The rate of cleavage (85.71% vs. 76.33%, respectively) and of reaching the blastocyst (44.15% vs. 32.54%, respectively) in the MFSC group were higher than the control group. In addition, it was determined that the numbers of ICM (45.8 ± 2.04 vs. 39.2 ± 1.85, respectively), TE (122.13 ± 2.19 vs. 115.0 ± 2.61, respectively), TC (167.93 ± 2.89 vs. 154.2 ± 2.62, respectively) increased in the MFSC group compared to the control group. A statistically significant difference was found in the number of cells with apoptosis per embryo (5.14 ± 0.77 vs. 11.91 ± 0.79) and apoptotic index rates (3.06 ± 0.47 vs. 7.72 ± 0.55%) of the MFSC and Con groups. As a result, we concluded that using microfluidic sperm sorting chips during sperm treatment in bovine IVEP increases the rate of reaching the blastocyst, embryo development, and quality and reduces the possibility of apoptosis in developing blastocysts. For this reason, it is also thought that the use of microfluidic sperm sorting devices during sperm treatment in bovine IVEP may be a new alternative in this field.

Evaluation of the Attitudes and Opinions of Veterinary School Students on Distance Education During the COVID-19 Pandemic.

This study aimed to determine the attitudes and opinions of the students of veterinary schools in Turkey regarding distance education during the COVID-19 pandemic. The study was conducted in two stages: (1) develop and validate a scale for assessing Turkish veterinary students' attitudes and opinions regarding distance education (DE) (n = 250 students; one veterinary school) and (2) widespread use of this scale amongst veterinary students (n = 1,599 students, 19 veterinary schools). Stage 2 was conducted between December 2020 and January 2021 with students from Years 2, 3, 4, and 5 who had experienced both face-to-face and distance education. The scale contained 38 questions, which were divided into seven sub-factors. Most students considered that practical courses (77.1%) should not continue to be delivered by DE; and that catch-up face-to-face programs (77%) would be required for practical skills after the pandemic. The main benefits of DE were that studies did not have to be interrupted (53.2%) and the ability to retrieve online video material for later study (81.2%). A total of 69% of students considered that DE systems and applications are easy to use. Many (71%) students considered that the use of DE would adversely affect their professional skills, 26.5% expected that the duration of their studies would be extended, but only 18.1% had considered suspending their studies for the period of the pandemic. Therefore, it appeared that face-to-face education was considered indispensable by students in veterinary schools, which provide practice-oriented education in the field of health sciences. However, the DE method can be used as a supplementary tool.

Choroidal Vascularity Index and Choroidal Thickness Changes Following Renal Transplantation.

Objectives: This study aimed to evaluate changes in subfoveal choroidal thickness (SFCT), choroidal vascularity index (CVI), estimated glomerular filtration rate (GFR), mean arterial pressure (MAP), and intraocular pressure (IOP) after renal transplantation. Materials and Methods: A total of 49 renal transplantation patients were included in this prospective study. CVI and SFCT on enhanced-depth imaging optic coherence tomography (EDI-OCT), MAP at the cubital fossa, GFR, and IOP were measured preoperatively and at postoperative 1 week and 1 month. In the analysis of EDI-OCT images, luminal area (LA) and stromal area of the choroid were determined using the image binarization method. CVI was defined as the ratio of LA to total choroid area. The effects of GFR, IOP, and MAP on CVI and SFCT were investigated. Results: The study included 23 women (47%) and 26 men (53%) with a mean age of 26.28±8.25 years (range: 18-52). Changes between preoperative, postoperative 1-week, and postoperative 1-month GFR values, CVI, and SFCT measurements were evaluated. There were significant differences between preoperative and postoperative GFR and SFCT measurements (p<0.001), but no significant differences between preoperative and postoperative CVI (p=0.09), MAP (p=0.14), or IOP (p=0.84) measurements. Conclusion: The present study demonstrated that SFCT increased significantly with GFR, while there was no change in CVI values.

Differentiating abdominal pain due to COVID-19 associated multisystem inflammatory syndrome from children with acute appendicitis: a score system.

PURPOSE: Differentiating abdominal pain due to coronavirus disease (COVID-19)-associated multisystem inflammatory syndrome (MIS-C) in children with acute appendicitis (AA) can cause diagnostic dilemmas. This study aimed to evaluate the efficacy of a previously described scoring system and improve its diagnostic ability in differentiating between these diseases. METHODS: This study was conducted between March 2020 and January 2022. Patients who had MIS-C with gastrointestinal system (GIS) involvement and patients who underwent surgery for appendicitis were included. First, all patients were evaluated using the new scoring system (NSS). The groups were compared by adding new MISC-specific parameters to NSS. The scoring system was evaluated using propensity score matching (PSM). RESULTS: A total of 35 patients with abdominal pain due to GIS involvement in MIS-C (group A) and 37 patients with AA who had ALT, PRC, and D-dimer results at their first admission (group B) were included in the study. The mean age of patients in group A was lower than that of patients in group B (p < 0.001). False NSS positivity was found in 45.7% of the patients with MIS-C. Lymphocyte (p = 0.021) and platelet counts (p = 0.036) were significantly lower in the blood count and serum D-dimer (p = 0.034), C-reactive protein (CRP) (p < 0.001), and procalcitonin (p < 0.001) were significantly higher in the MIS-C group. We created a scoring system called the Appendicitis-MISC Score (AMS) using the NSS and new parameters. The sensitivity and specificity of AMS diagnostic scores were 91.9% and 80%, respectively. CONCLUSION: MIS-C with GIS involvement may present as acute abdomen. It is difficult to differentiate this condition from acute appendicitis. AMS has been shown to be useful for this differentiation.

Correlation of brain segmental volume changes with clinical parameters: a longitudinal study in multiple sclerosis patients.

OBJECTIVE: To measure the cranial volume differences from 15 different parts in the follow-up of relapsing-remitting multiple sclerosis (RRMS) patients and correlate them with clinical parameters. METHODS: Forty-seven patients with RRMS were included in the study. Patients were grouped into two categories; low Expanded Disability Status Scale (EDSS) (< 3; group 1), and moderate-high EDSS (≥ 3; group 2). Patients were evaluated with Beck Depression Inventory (BDI), Montreal Cognitive Assessment (MOCA), Symbol Digit Modalities Test (SDMT), Fatigue Severity Scale (FSS), and calculated Annualized Relapse Rate (ARR) scores. Magnetic resonance imaging (MRI) was performed with a 1.5T MRI device (Magnetom AERA, Siemens, Erlangen, Germany) twice in a 1-year period. Volumetric analysis was performed by a free, automated, online MRI brain volumetry software. The differences in volumetric values between the two MRI scans were calculated and correlated with the demographic and clinical parameters of the patients. RESULTS: The number of attacks, disease duration, BDI, and FSS scores were higher in group 2; SDMT was higher in group 1. As expected, volumetric analyses have shown volume loss in total cerebral white matter in follow-up patients (p < 0.001). In addition, putaminal volume loss was related to a higher number of attacks. Besides, a negative relation between FSS with total amygdala volumes, a link between atrophy of globus pallidus and ARR, and BDI scores was found with the aid of network analysis. CONCLUSIONS: Apart from a visual demonstration of volume loss, cranial MRI with volumetric analysis has a great potential for revealing covert links between segmental volume changes and clinical parameters.

OBJETIVO: Medir as diferenças de dominância craniana de 15 regiões diferentes no seguimento de pacientes com esclerose múltipla recorrente-remitente (EMRR) e correlacioná-las com parâmetros clínicos. MéTODOS: Quarenta e sete pacientes com EMRR foram incluídos no estudo. Os pacientes foram agrupados em duas categorias; EDSS baixo (< 3; grupo 1) e EDSS médio-alto (≥ 3; grupo 2). Os pacientes foram avaliados com o Inventário de Depressão de Beck (BDI, na sigla em inglês), Montreal Cognitive Assessment (MOCA, na sigla em inglês), Symbol Digit Modality Tests (SDMT, na sigla em inglês), Fatigue Severity Scale (FSS, na sigla em inglês) e taxa de ataque anual (ARR, na sigla em inglês). Duas ressonâncias magnéticas (RMs) foram feitas em um ano com um aparelho de imagem de 1,5 T MR (Magnetom AERA, Siemens, Erlangen, Alemanha). A análise de volume foi realizada com um software de medição mestre cerebral de RM gratuito e automatizado. As diferenças volumétricas entre os dois exames de RM foram calculadas e correlacionadas com os parâmetros demográficos e clínicos dos pacientes. RESULTADOS: Número de crises, duração da doença, escores BDI e FSS foram mais elevados no grupo 2; as pontuações do SDMT foram maiores no grupo 1. Como esperado, as análises volumétricas mostraram perda total de volume de substância branca no seguimento (p < 0,001). Além disso, a perda da dominância putaminal foi associada ao maior número de ataques. Além disso, uma relação negativa entre FSS e volume total da amígdala, e uma correlação entre ARR e BDI e atrofia do globo pálido foi determinada com a ajuda da análise de rede. CONCLUSõES: Além da demonstração visual da perda de volume, a RM com análise volumétrica tem grande potencial para revelar alterações segmentares dominantes e conexões ocultas entre parâmetros clínicos.

Genetic, Surgical and Oncological Approach to Breast Cancer, with BRCA1, BRCA2, CDH1, PALB2, PTEN and TP53 Variants.

Objective: The aim of this study was to determine the frequency of germline variants in BRCA1, BRCA2, CDH1, PALB2, PTEN and TP53 in patients admitted to a medical genetics clinic with breast cancer and to assess these identified variants according to published genetic, surgical and oncological perspectives. Materials and Methods: Medical history, and cancer diagnosis information for 195 independent probands with operated breast cancer were collected from requisition forms and medical records. The exonic regions and exon-intron junctions in BRCA1, BRCA2, CDH1, PALB2, PTEN and TP53 genes were sequenced. Analysis of fastq files was performed on the Qiagen Clinical Insight-Analyse Universal with panel-specific pipeline and vcf files were interpreted clinically using Qiagen Clinical Insight-Interpret. Results: Gene variants (pathogenic, likely pathogenic and variants of unknown significance) were detected in 53 (27.2%). Detailed information about the patients (age of diagnosis, family history, gender), cancer stage, tumour characteristics (ER, PR, human epidermal growth factor receptor 2 status) and all information related to the detected variants (gene, location, nucleotide and amino acid change, exon number, impact, mutation classification, dbSNP number and HGMD variant class) were assessed. In total, 58 mutations were identified including 14 novel, previously unreported variants. Conclusion: Molecular characterization and identification of mutations have important implications for predictive, preventive, and personalized medicine, including genetic counseling and development of specific treatment protocols. We emphasize variants of unknown significance (VUS) as the clinical significance of VUS changes over time and variant classification is important for clinical molecular genetic testing and clinical guidance. This study may provide new insights into risk assessment for variants in CDH1, PALB2, PTEN and TP53, in addition to BRCA1 and BRCA2, which may prove useful for clinical management of breast cancer patients. Further studies are needed to identify the common gene variants in the Turkish population and evaluate the pathogenity of VUS.

Is there a relationship between fall status, cognition and cerebellar lobule volume in patients with multiple sclerosis?

In this prospective case control study, relationship of detailed cerebellar volumetric data and cognition in patients with multiple sclerosis considering falling status using 3 D MRI and network analysis were evaluated. Participants consist of 106 adults with relapsing-remitting multiple sclerosis. Scores of Montreal cognitive assessment test, symbol digit modality Test, nine-hole peg test, berg balance scale test, timed up and go test, timed 25-foot walk test were worse in faller group than non faller group (p < 0.05 for all tests). There was no significant difference in terms of cerebellar lobule volumes between groups. But using artificial intelligence (AI) based network analysis, we brought a new perspective to interpreting the relationship between the cerebellum, cognition, gait, and balance. Overall, data from the study suggest a possible relationship between cerebellar volume changes and cognitive dysfunction through connectivity analysis in patients with multiple sclerosis. Further studies are needed to examine this issue by using connectivity analysis.

The Safety and Tolerability of Nebivolol in Hypertensive Patients with Coronary Artery Disease and Left Ventricular Ejection Fraction ≥ 40%: A Population-Based Cohort Study (Nebivolol-TR Study).

BACKGROUND: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort. METHODS: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. RESULTS: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. CONCLUSION: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

A Combination of Heart Rate-Corrected QT Interval and GRACE Risk Score Better Predict Early Mortality in Patients with Non-ST Segment Elevation Acute Coronary Syndrome.

OBJECTIVE: This study aimed to evaluate whether the addition of heart rate-corrected QT inter- val prolongation to the Global Registry of Acute Coronary Events risk score improves the pre- dictive value for early mortality in patients with non-ST segment elevation acute coronary syndrome. METHODS: We retrospectively screened our database for consecutive non-ST-segment eleva- tion acute coronary syndrome patients between January 2017 and July 2019. The demographic and clinical parameters were acquired via chart review. All electrocardiograms were reviewed by 2 physicians. QT interval was measured using the tangent method. Early mortality was defined as all-cause death observed during the hospital stay or within 30 days after discharge. RESULTS: The final study population consisted of 283 patients, there were 17 early deaths. Ten of 59 patients with prolonged corrected QT intervals died (16.9%, P < .001). Both the Global Registry of Acute Coronary Events risk score (odds ratio: 1.032; 95% CI: 1.012-1.053; P = .002) and corrected QT interval (odds ratio: 1.026; 95% CI: 1.007-1.045; P = 0.007) independently predicted early mortality. The area under value was 0.769 (95% CI: 0.674-0.863, P < .001) for the corrected QT interval and 0.780 (95% CI:0.681-0.878; P < .001) for the Global Registry of Acute Coronary Events risk score alone. However, when the corrected QT interval and the Global Registry of Acute Coronary Events risk score were combined, it was found to be 0.808 (95% CI: 0.713-0.904, P < .001). CONCLUSION: This study is the first to report that prolonged corrected QT and the Global Registry of Acute Coronary Events risk score independently predict early mortality and a combina- tion of these 2 factors may improve the predictive value for early mortality in patients with ST-segment elevation acute coronary syndrome.

Re-evaluating hypertension in children according to different guidelines: a single-center study.

We aimed to evaluate the agreements between the guidelines used for both office blood pressure (OBP) and ambulatory blood pressure monitoring (ABPM). Our secondary aim was to define the best threshold to assess children at risk of left ventricular hypertrophy (LVH). Thresholds proposed by the Fourth Report (FR), European Society of Hypertension (ESH), and American Academy of Pediatrics (AAP) for OBP and the Wühl, ESH, and American Heart Association (AHA) for ABPM were used, and nine different BP phenotype combinations were created. The agreements between the thresholds, the sensitivity of the thresholds, and the BP phenotypes used to predict LVH were determined in 949 patients with different ages and body mass indices (BMIs). The agreements between the guidelines for OBP and ABPM were "good" and "very good" (κ = 0.639; 95% CI, 0.638-0.640, κ = 0.986; 95% CI, 0.985-0.988), respectively. To classify OBP and ABPM into BP phenotypes, we obtained nine different combinations, which had "very good" agreement (κ = 0.880; 95% CI, 0.879-0.880). The sensitivity of AAP for detecting LVH was the highest in <12-year-old obese children (S = 75.8, 95% CI, 56.4-89.7). The sensitivity of ABPM in detecting LVH was similar among different age and BMI groups. The sensitivity of different BP phenotypes tended to be higher in the groups where OBP was evaluated according to AAP. The highest sensitivity was detected in the 13- to 15-year-old normal weight group.(S: 88.8, 95% CI, 51.7-99.7). The AAP guideline is more sensitive and decisive for BP phenotypes to detect LVH, especially in normal-weight children ≤ 15 years, while ABPM thresholds for children have limited effect.

Gut dysbiosis may be associated with hyperemesis gravidarum.

PURPOSE: In this study, we aimed to determine the frequency of different intestinal microorganisms of patients with normal pregnancies and HG and to compare these frequencies between the two groups. MATERIALS AND METHODS: This case-control study was carried out in Baskent University Department of Obstetrics and Gynecology and included 20 patients; 10 of whom had normal pregnancies and 10 of whom had HG. A stool flora scan was routinely planned for all patients. Transient and continuous fecal bacteria and fungal flora were analyzed. All data were evaluated statistically and their relationships with clinical condition were discussed. RESULTS: The study group consisted of 20 pregnant women with a mean age of 31.5 years. All patients were nonsmokers and free of chronic diseases and of any medications. Aerobic and anaerobic bacteria groups, fungal colonies, and parasites were examined and bowel pH values were measured separately for each patient. Bacterial and fungal species outside the reference ranges were recorded for each patient. There was a statistically significant increase in Clostridium spp. (p:.01) and Candida spp. (p:.033) and a statistically significant decrease in Bifidobacterium spp.(p:.008) in patients with HG compared to women with normal pregnancies. There was a significant difference between the group with HG and the group with normal pregnancies in terms of flora dysbiosis (p:.001). CONCLUSION: Our results suggest that gut dysbiosis may be a factor in HG. The effect of the severity of gut dysbiosis on the disease may be the subject of future studies.
