Artificial intelligence assisted ultrasound for the non-invasive prediction of axillary lymph node metastasis in breast cancer

PurposeA practical noninvasive method is needed to identify lymph node (LN) status in breast cancer patients diagnosed with a suspicious axillary lymph node (ALN) at ultrasound but a negative clinical physical examination. To predict ALN metastasis effectively and noninvasively, we developed an artificial intelligence-assisted ultrasound system and validated it in a retrospective study.MethodsA total of 266 patients treated with sentinel LN biopsy and ALN dissection at Peking Union Medical College & Hospital(PUMCH) between the year 2017 and 2019 were assigned to training, validation and test sets (8:1:1). A deep learning model architecture named DeepLabV3 + was used together with ResNet-101 as the backbone network to create an ultrasound image segmentation diagnosis model. Subsequently, the segmented images are classified by a Convolutional Neural Network to predict ALN metastasis.ResultsThe area under the receiver operating characteristic curve of the model for identifying metastasis was 0.799 (95% CI: 0.514–1.000), with good end-to-end classification accuracy of 0.889 (95% CI: 0.741–1.000). Moreover, the specificity and positive predictive value of this model was 100%, providing high accuracy for clinical diagnosis.ConclusionThis model can be a direct and reliable tool for the evaluation of individual LN status. Our study focuses on predicting ALN metastasis by radiomic analysis, which can be used to guide further treatment planning in breast cancer.

Interaction of Th17 differentiations-related gene polymorphisms and environmental factors contributing to the disease classification, complications, and surgical risks of Crohn's disease in the Chinese Han population.

Few studies have been conducted on gene-environment interactions in the Chinese population with Crohn's disease (CD). We aimed to investigate the association between single nucleotide polymorphisms (SNPs) on the T helper 17 (Th17) cell and CD susceptibility/performance in Chinese individuals. We conducted a case-control and case-only study at the Peking Union Medical College Hospital. Four SNPs related to the Th17 cell pathway genes were prioritized, including rs2284553 (interferon gamma receptor 2), rs7517847 (interleukin 23 receptor), rs7773324 (interferon regulatory factor 4), and rs4263839 (tumor necrosis factor superfamily 15). SNP frequency was calculated, and gene-environment interaction was assessed by multifactor dimensionality reduction analysis. Altogether 159 CD patients and 316 healthy controls were included. All analyzed SNPs were found in Hardy-Weinberg equilibrium (P > 0.05). The frequency of rs2284553-A allele and rs4263839-A allele were lower in CD patients compared with controls (P < 0.05). While the rs4263839-A allele was more prevalent in ileocolonic CD patients than in those with isolated small intestinal or colonic disease (P = 0.035). Gene-environment interactions revealed associations between rs2284553 and breastfeeding, sunshine exposure, and fridge-stored food, affecting age at diagnosis, intestinal involvement, and intestinal stricture. Interaction of rs4263839 and breastfeeding influenced small intestinal lesions and intestinalstricture in CD. This study provided information on the genetic background in Chinese CD patients. Incorporating these SNPs into predictive models may improve risk assessment and outcome prediction. Gene-environment interaction contributes to the understanding of CD pathogenesis.

Effects of Bifidobacterium bifidum tetragonum tablets and Jin Gui Ren Qi Pill on intestinal flora and metabolism in patients with diabetic kidney disease

ObjectiveTo investigate the effects of Bifidobacterium bifidum tetragonum tablets and Jin Gui Ren Qi Pill on intestinal flora and metabolism in patients with diabetic kidney disease.MethodsIn the study conducted at Heping Hospital of Changzhi Medical College from March 2021 to December 2022, 30 cases of patients diagnosed with diabetic nephropathy were meticulously selected as study subjects. Employing a double-blind randomized table method, these patients were randomly allocated into three groups: the control group (n = 10), the Bifidobacterium bifidum tetragonum tablets group (n = 10), and the Jin Gui Ren Qi Pill group (n = 10). The control group received standard western medical treatments for diabetic nephropathy, including serum glucose, blood lipids, blood pressure management, and other conventional therapies. In addition to the standard treatments, the Bifidobacterium bifidum tetragonum tablets group received Bifidobacterium bifidum tetragonum tablets, while the Jin Gui Ren Qi Pill group received Jin Gui Ren Qi Pill. Before and after a 4-week treatment period, various baseline parameters were assessed, including fasting blood glucose, 2-h postprandial blood glucose, triglycerides, serum total cholesterol, serum low-density lipoprotein cholesterol, serum high-density lipoprotein cholesterol, random urine microalbumin/creatinine ratio (ACR), blood creatinine (SCr), and traditional Chinese medicine evidence scores. Stool specimens were collected from all three groups before and after treatment for 16S rDNA high-throughput sequencing, followed by comprehensive analyses including OUT clustering, Alpha diversity, Beta diversity, species composition analysis, LEfSe analysis, and KEGG function prediction. Spearman correlation analysis was employed to explore the relationship between intestinal flora and clinical indicators. Furthermore, fasting peripheral venous blood was collected from patients in the Bifidobacterium tetrapunctate tablets group and the control group before and after intervention to measure the optical density values of tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), and interleukin-6 (IL-6) using the Beijing Biolite ELISA kit. This study was conducted with the approval of the Ethics Committee of Changzhi Medical College.Results1. The 2hPBG, total cholesterol and LDL levels were observed among patients with diabetic kidney disease (DKD) across all groups: the Jin Gui Ren Qi Pill group, the Bifidobacterium bifidum tetragonum tablets group, and the control group (p &amp;lt; 0.05). 2. The Jin Gui Ren Qi Pill demonstrated superior efficacy in alleviating TCM symptoms and reducing the ACR compared to both the Bifidobacterium bifidum tetragonum tablets group and the control group. Conversely, Bifidobacterium bifidum tetragonum tablets exhibited a more pronounced reduction in TC levels compared to both the Jin Gui Ren Qi Pill and control groups. Notably, Bifidobacterium bifidum tetragonum tablets effectively decreased (IL-2) levels in patients with DKD. 3. Bifidobacterium bifidum tetragonum tablets also demonstrated efficacy in reducing IL-2 levels in DKD patients. 4. Analysis of intestinal microorganism abundance and diversity before and after the intervention, as well as among the three groups, revealed no significant alterations. Similarly, comparisons of ACE, Chao, Simpson, and Shannon indices showed no statistically significant differences (p &amp;gt; 0.05). 5. Qualitative analysis of intestinal microorganisms before and after intervention, as well as among the three groups, indicated no significant differences. Anosim test results also did not reveal qualitative distinctions (Anosim test R = 0.021, p = 0.215). 6. LEfSe analysis unveiled a noteworthy increase in Prevotella_7 abundance within the Jin Gui Ren Qi Pill group post-intervention (p &amp;lt; 0.05). 7. Furthermore, Chinese medicine evidence scores, body mass index, TC, and LDL levels correlated positively with the relative abundance of Tyzzerella_3 bacterial flora. Conversely, age, disease duration, and 2hPBG correlated positively with the relative abundance of Christensenellaceae_R_7 flora, while TC and LDL levels displayed a negative correlation with the relative abundance of Christensenellaceae_R_7 flora.ConclusionThe combination of Jin Gui Ren Qi Pill with western medical treatment exhibited superior efficacy in ameliorating clinical symptoms and reducing the ACR in patients with DKD compared to western medical treatment alone. Furthermore, this combination therapy led to an increase in the abundance of Prevotella_7 within the intestinal flora of patients, suggesting a potential enhancement in carbohydrate metabolism by the intestinal microbiota. On the other hand, Bifidobacterium bifidum tetragonum tablets bacterial tablets combined with western medical treatment demonstrated enhanced efficacy in reducing TC levels in DKD patients compared to western medical treatment alone. Additionally, this combination therapy effectively reduced the levels of IL-2 in DKD patients, thus mitigating inflammation in these individuals.

The impact of pre-operative uric acid levels on post-operative renal outcomes in off-pump coronary artery bypass grafting patients

Background: Elevated pre-operative uric acid levels significantly impact post-operative renal outcomes in off-pump CABG patients, increasing the risk of acute kidney injury, as evidenced by higher serum creatinine and reduced urine output. Methods: This cross-sectional study was conducted in Department of Cardiac Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka, Bangladesh from January 2021 to December 2022. Total 160 patients undergoing off pump CABG were divided into two groups, group A and group B, each containing 80 patients. In group A, uric acid level was &lt;7 mg/dl for male and &lt;6 mg/dl for female and in group B, it was &gt;7 mg/dl and &gt;6 mg/dL for female. Results: The demographic characteristics, pre-operative serum UA levels and serum creatinine levels between the two groups was not statistically significant. Group A had shorter operative times (mean 265.21±53.33 minutes) compared to Group B (mean 327.04±44.32 minutes), with more patients in Group-B undergoing longer surgeries (&gt;360 minutes). Group-B also had more grafts (mean 4.4 vs 3.6), higher serum creatinine (1.91 vs 1.17 mg/dl), bilirubin (0.8 vs 0.7 mg/dl), and lower urine output (mean 47.52 vs 95.37 ml/hour), all statistically significant (p&lt;0.001). Conclusions: This study concludes that there is significant impact of pre-operative uric acid levels on post-operative renal outcomes in off-pump CABG patients.

Trifecta outcomes of robotic partial nephrectomy in obese patients: A comparison of body mass index

We analyzed robotic partial nephrectomy (RPN) outcomes in obese patients based on body mass index (BMI) and trifecta achievement. We retrospectively reviewed 296 patients who underwent RPN at Kansai Medical University Hospital between 2014 and 2022. The preoperative clinical data and perioperative outcomes were evaluated. Trifecta achievement (negative surgical margin, no major complications, and no acute kidney injury on postoperative day three) and its relationship to three BMI groups (<25, 25 to <30, and ≥30) were the primary outcome. The correlation between factors in achieving trifecta and BMI was evaluated. Univariate and multivariate analyses assessed variables for achieving the trifecta with logistic regression analysis. C-statistics quantitatively evaluated the prediction accuracy. Among 296 patients, 264 (89.2%) achieved trifecta (BMI categories were <25 [89.9%], 25 to <30 [89.4%], and ≥30 [82.6%]). There was no significant BMI-related difference (p = 0.566). Intraoperative blood loss increased with the BMI (p = 0.034). Multivariate analyses showed preoperative aspects and dimensions used for anatomic (PADUA) score independently predicted trifecta failure (odds ratio 1.71; 95% confidence interval 1.32-2.20; p < 0.001). The C-statistics of the PADUA score increased with increasing BMI. Higher BMI patients had more intraoperative blood loss during RPN. However, RPN remains safe and has acceptable quality and functional outcomes. Since patients with high PADUA scores combined with a high BMI may be at risk of trifecta failure, this should be explained before RPN.

Evaluation of the Management and Outcome of Patients with Retained Products of Conception after Gestational Week 23+0: A Retrospective Cohort Study

Background: Retained products of conception after childbirth or miscarriage are associated with an increased rate of maternal complications, such as abnormal vaginal bleeding and infections. Late complications may also include intrauterine adhesions, causing infertility. Surgical interventions carry a certain risk. Thus, conservative management is often discussed as an alternative. The aim of this study was to assess the clinical outcomes of patients with retained products of conception, comparing a primary surgical approach to conservative management. Methods: We conducted a retrospective cohort study of 88 patients diagnosed with retained products of conception after 23+0 weeks of gestation at the Medical University Vienna between 2014 and 2022. Results: Forty-seven (53.4%) patients underwent primary surgical management and 41 (46.6%) primary conservative management. After primary conservative treatment, a complication could be observed in 10 (24.4%) women. In contrast, complications occurred in 32 (68.1%) women in the group with primary surgical treatment (p &lt; 0.001). The most common complication in both groups was the ongoing suspicion of retained products of conception. Patients after primary surgical treatment were significantly more likely to require a secondary change in treatment (p &lt; 0.001). Ultimately, secondary conservative management was applied in 30 (63.8%) patients. In contrast, only nine (21.95%) patients with primary conservative management required secondary surgical management. Conclusions: Due to the high risk of complications and persistent retained products of conception, primary surgical management should only be prioritized in hemodynamically instable or septic patients.

The article is devoted to the current problem of the formation of the professional personality of medical students from the point of view of basic values, such as citizenship and responsibility, corresponding to the new demands of society, lying in the plane of the modern Concept of Zhana Kazakhstan. The purpose of the article is to formulate the principle of the effectiveness of using a quiz in classroom and extracurricular work with students of medical specialties. The authors offer a specific scenario for the quiz «Medical Karaganda», and at the same time describe in detail the tasks and the course of the game. The tasks are based on materials on the history of medicine in Karaganda, including unique archival sources, materials collected in museums and other sources. The quiz also involves conducting it in the second language that the students are studying (in this case, Russian for students in groups with Kazakh as the language of tuition). The article analyzes both the effectiveness of individual tasks and the quiz as a whole. The analysis was carried out based on the results of testing a quiz in the classroom (NС JSC «Karaganda Medical University», 1st year students) and as part of the «City Day» event at the private institution «Bolashaq Academy» with students of the specialty «Pharmacy». Analysis of the results obtained during feedback and questioning proved the effectiveness of the quiz in the formation of basic values (patriotism, responsibility, critical thinking) and allowed us to formulate the principle of effectiveness based on a careful selection of tasks and interdisciplinary connections.

The diabetic parkinsonian – the association of diabetes mellitus comorbidity and symptoms of Parkinson’s disease

Introduction and objective: Many studies have investigated the interplay between Parkinson’s disease and diabetes mellitus, suggesting that glucose metabolism impairment may worsen the clinical course of Parkinson’s disease. This study aimed to explore the association between diabetes mellitus and the course of Parkinson’s disease. Materials and methods: A retrospective study was performed by analysing the clinical data of patients diagnosed with Parkinson’s disease who were hospitalised in University Clinical Centre of the Medical University of Silesia from 2019 to 2021. The study group comprised 241 patients selected according to the study’s inclusion and exclusion criteria. Their clinical conditions were assessed using body mass index, the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), the Hoehn–Yahr scale, Mini-Mental State Examination (MMSE), Clock Drawing Test (CDT) and Beck Depression Inventory (BDI). Data were collected on current anti-parkinsonian treatment, fasting glycaemia, lipid panel, and thyroid stimulating hormone, homocysteine and vitamin D3 levels. Results: The study group included 31 patients diagnosed with diabetes mellitus and 240 patients without glucose metabolism impairment. Both groups were matched by considering age, disease duration, and gender distribution. Diabetic patients displayed a higher MDS-UPDRS part III OFF rating (42 [31–55] vs. 48 [39–59]; p = 0.0043), higher MDS-UPDRS part III ON rating (17 [11–26] vs. 26.5 [19–32]; p = 0.0009) and higher BDI score (7 [4–11] vs. 11 [9–16]; p = 0.0013). As expected, patients with diabetes mellitus had a higher fasting glycaemia, total cholesterol, lower high-density lipoprotein cholesterol and higher body mass index. Conclusions: Our study confirms the relationship between diabetes mellitus and a worse clinical course for Parkinson’s disease.

Monitoring the level of satisfaction with the quality of training in pediatrics of undergraduates on the specialty 222 “Medicine” of the Faculty for Training of Foreign Citizens of the Bogomolets National Medical University

Background. Monitoring the level of satisfaction of undergraduates on the specialty 222 “Medicine” concerning their training in pediatrics and the level of mastering the necessary competencies is an important marker that allows timely assessment of the quality of the educational services provision, as well as the improvement and expansion of their range in relation to the students’ needs. Objective: to analyze the satisfaction level of the students’ training in pediatrics and to determine ways of improving the teaching of pediatric disciplines to the 6th year foreign students on the specialty 222 “Medicine” at the Department of Pediatrics 2 of the Bogomolets National Medical University based on the anonymous survey results. Materials and methods. The survey was conducted using 4–5-point Likert scale questionnaire in Google Form. Results. Practically all students were basically satisfied with the knowledge obtained in pediatric disciplines they studied at the Department of Pediatrics 2 from the 2nd to the 6th years, with a special emphasis on preparation during the graduation year. Only one third (34.7 %) of respondents in general noted that the organization and delivery of an online training did not deteriorate the quality of knowledge and practical skills in pediatrics. The respondents were particularly interested in sections of pediatrics such as cardiology, rheumatology, pulmonology and neonatology. The insufficient satisfaction of higher education seekers with level of their knowledge in propaedeutics of pediatrics, pathology of young children and pediatric cardiology requires a corresponding correction of the curriculum — an increase in the number of academic hours in these sections of pediatrics and more effective use of the self-directed independent learning. Conclusions. Monitoring the satisfaction level is an effective method of communication with medical undergraduates aimed at identifying problems and improving the effectiveness of training and educational process for foreign students, who in general positively evaluated the results of their five-year study of pediatric disciplines at the Department of Pediatrics 2 of the Bogomolets National Medical University.

Breast Self-Examination among Female Medical Students at Damascus University A cross-sectional study

IntroductionBreast cancer (BC) is the leading cause of death in Syria. In young females, it is a serious complication, making it crucial to raise awareness about the disease and its early detection methods. Given the challenging circumstances that Syrians face, regular visits to medical centers for mammography are often not feasible. Therefore, breast self-examination (BSE) is a valuable tool for detecting cancer. Educating girls in medical colleges is key to disseminating knowledge about BSE among women, as they will become future healthcare providers and can share accurate information with their families. Materials and methodsA cross-sectional study was conducted in the medical faculties of Damascus University (medicine, dentistry, and pharmacy), Syria. The study utilized a structured questionnaire on Google Forms with four sections. The questionnaire was prepared electronically, and shared as an online link in formal university groups on social media. Data collection started on September 19, 2022, and ended on October 19 of the same year. Participation was accepted from female students in medical colleges, ranging from second to fifth year (for dental and pharmacy students) and sixth year (for medical students). Data from other students and incomplete data were excluded. Results589 female medical students from three faculties (medicine, dentistry, and pharmacy) filled out the questionnaire. Only 57% of the students demonstrated a good attitude towards BSE, and 79.6% of them agreed or strongly agreed that they avoid BSE due to fear of the consequences of breast cancer. Regarding BSE knowledge, 89.6% of the participants reported previously hearing about BSE, and 55.7% of them had performed BSE before. The factors that were accompanied by better knowledge about BSE were: a good attitude towards BSE; previously performed BSE; studying in a medical faculty; study years for medical and pharmacy students; and higher college average grades. Whereas, having a medical relative and having a family member with a history of BC surprisingly do not impact the knowledge. ConclusionThe study, conducted at Damascus University in Syria, assessed the knowledge and practice of breast self-examination among female medical college students. The results indicate a moderate level of knowledge and limited practical experience in performing breast self-examination. These findings highlight the urgent need to emphasize the importance of promoting and teaching this method to a wider population of women in society.

Liver involvement with Langerhans cell histiocytosis in adults.

Liver involvement portends poor prognosis in adults. We aimed to characterize the clinical features, liver function tests, radiologic findings, molecular profiles, therapeutic approaches and outcomes of adults patients with Langerhans cell histiocytosis (LCH) with liver involvement. We conducted a retrospective analysis of all adults with LCH (≥ 18 years) seen at Peking Union Medical College Hospital (Beijing, China) between January 2001 and December 2022. Among the 445 newly diagnosed adults with LCH, 90 patients had liver involvement at diagnosis and 22 patients at relapse. The median age was 32 years (range, 18-66 years). Of 112 evaluable patients, 108 had full liver function testing, including alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), and total bilirubin and albumin. Elevated ALP was seen in 63.0% and GGT in 86.1%; 14.8% had elevated bilirubin. Next-generation sequencing of 54 patients revealed frequent BRAFN486_P490 (29.6%), BRAFV600E (18.5%), and MAP2K1 (14.8%). After a median 40 months' follow-up (range 1-168 months), 3-year progression-free survival (PFS) and overall survival were 49.7% and 86.6% respectively. In multivariable analyses, ≥3 abnormal liver function tests (HR 3.384, 95% CI 1.550-7.388, P = .002) associated with inferior PFS; immunomodulatory drug therapy (HR 0.073, 95% CI, 0.010-0.541, P = .010) correlated with superior PFS versus chemotherapy. In summary, elevated GGT and ALP were common in adults with LCH liver involvement. Greater than equal to 3 abnormal liver function tests predicted poor outcomes. Immunomodulatory drug therapy was associated with favorable progression-free survival compared to chemotherapy.

Correlation between abdominal computed tomography signs and postoperative prognosis for patients with colorectal cancer.

Patients with different stages of colorectal cancer (CRC) exhibit different abdominal computed tomography (CT) signs. Therefore, the influence of CT signs on CRC prognosis must be determined. To observe abdominal CT signs in patients with CRC and analyze the correlation between the CT signs and postoperative prognosis. The clinical history and CT imaging results of 88 patients with CRC who underwent radical surgery at Xingtan Hospital Affiliated to Shunde Hospital of Southern Medical University were retrospectively analyzed. Univariate and multivariate Cox regression analyses were used to explore the independent risk factors for postoperative death in patients with CRC. The three-year survival rate was analyzed using the Kaplan-Meier curve, and the correlation between postoperative survival time and abdominal CT signs in patients with CRC was analyzed using Spearman correlation analysis. For patients with CRC, the three-year survival rate was 73.86%. The death group exhibited more severe characteristics than the survival group. A multivariate Cox regression model analysis showed that body mass index (BMI), degree of periintestinal infiltration, tumor size, and lymph node CT value were independent factors influencing postoperative death (P < 0.05 for all). Patients with characteristics typical to the death group had a low three-year survival rate (log-rank χ 2 = 66.487, 11.346, 12.500, and 27.672, respectively, P < 0.05 for all). The survival time of CRC patients was negatively correlated with BMI, degree of periintestinal infiltration, tumor size, lymph node CT value, mean tumor long-axis diameter, and mean tumor short-axis diameter (r = -0.559, 0.679, -0.430, -0.585, -0.425, and -0.385, respectively, P < 0.05 for all). BMI was positively correlated with the degree of periintestinal invasion, lymph node CT value, and mean tumor short-axis diameter (r = 0.303, 0.431, and 0.437, respectively, P < 0.05 for all). The degree of periintestinal infiltration, tumor size, and lymph node CT value are crucial for evaluating the prognosis of patients with CRC.

The effect of prognostic nutritional index on diabetic patients with myocardial infarction

BackgroundThe prognostic nutritional index (PNI), a simple and comprehensive predictor of nutritional and immunological health, is connected to cancer and cardiovascular disease. The effects of PNI on myocardial infarction (MI) in individuals with diabetes remain unclear. Thus, we aim to investigate the correlation of PNI with predictive outcomes in this specific population group to inform therapeutic decision-making.MethodsThis prospective observational study included 417 diabetic patients with MI who underwent coronary angiography intervention at Fujian Medical University Union Hospital from May 2017 to May 2020. We collected follow-up and prognostic data from these patients at 6, 12, 18, and 24 months post-procedure via outpatient visits or phone interviews. The main focus of the study was on major adverse cardiovascular events (MACE) in the two years after surgery. Based on the median PNI, patients were categorized into two groups: high PNI (H-PNI) and low PNI (L-PNI). Data were analyzed using IBM SPSS 25.0. Kalpan-Meier survival curves and Cox proportional hazards regression analysis were utilized to examine the associations between preoperative PNI and the prognosis of diabetic patients with MI.ResultsIn the study, 417 participants were observed for two years. Of these patients, 159 (38.1%) had MACE. According to the Kaplan–Meier curves, patients in the L-PNI group had more MACE than those in the H-PNI group (log-rank p < 0.001) and had a heightened susceptibility to all categories of MACE. After adjusting for confounding variables, the corrected hazard ratio for developing unstable angina in the L-PNI group was 2.55 (95% CI 1.57–4.14, p < 0.001).ConclusionLow PNI levels are associated with MACE after coronary angiography intervention in diabetic patients with myocardial infarction. This highlights the prognostic value of PNI and broadens its potential use in larger populations.Trial registration: Not applicable.

Interaction between the albumin-bilirubin score and nutritional risk index in the prediction of post-hepatectomy liver failure.

Post-hepatectomy liver failure (PHLF) is the most common postoperative complication and the leading cause of death after hepatectomy. The albumin-bilirubin (ALBI) score and nutritional risk index (NRI) have been shown to assess end-stage liver disease and predict PHLF and patient survival. We hypothesized that the ALBI score and NRI interact in the prediction of PHLF. To analyze the interaction between the ALBI score and NRI in PHLF in patients with hepatocellular carcinoma. This retrospective study included 186 patients who underwent hepatectomy for hepatocellular carcinoma at the Affiliated Hospital of Youjiang Medical University for Nationalities between January 2020 and July 2023. Data on patient characteristics and laboratory indices were collected from their medical records. Univariate and multivariate logistic regression were performed to determine the interaction effect between the ALBI score and NRI in PHLF. Of the 186 patients included in the study, PHLF occurred in 44 (23.66%). After adjusting for confounders, multivariate logistic regression identified ALBI grade 2/3 [odds ratio (OR) = 73.713, 95% confidence interval (CI): 9.175-592.199] and NRI > 97.5 (OR = 58.990, 95%CI: 7.337-474.297) as risk factors for PHLF. No multiplicative interaction was observed between the ALBI score and NRI (OR = 0.357, 95%CI: 0.022-5.889). However, the risk of PHLF in patients with ALBI grade 2/3 and NRI < 97.5 was 101 times greater than that in patients with ALBI grade 1 and NRI ≥ 97.5 (95%CI: 56.445-523.839), indicating a significant additive interaction between the ALBI score and NRI in PHLF. Both the ALBI score and NRI were risk factors for PHLF, and there was an additive interaction between the ALBI score and NRI in PHLF.

Treatment of three pediatric AML co-expressing NUP98-NSD1, FLT3-ITD, and WT1

During the treatment of 89 pediatric patients with Acute Myeloid Leukemia (AML) at the Hematology Department of Kunming Medical University’s Children’s Hospital from 2020 to 2023, three patients were identified to co-express the NUP98-NSD1, FLT3-ITD, and WT1 gene mutations. The bone marrow of these three patients was screened for high-risk genetic mutations using NGS and qPCR at the time of diagnosis. The treatment was administered following the China Children’s Leukemia Group (CCLG)-AML-2019 protocol. All three patients exhibited a fusion of the NUP98 exon 12 with the NSD1 exon 6 and co-expressed the FLT3-ITD and WT1 mutations; two of the patients displayed normal karyotypes, while one presented chromosomal abnormalities. During the induction phase of the CCLG-AML-2019 treatment protocol, the DAH (Daunorubicin, Cytarabine, and Homoharringtonine) and IAH (Idarubicin, Cytarabine, and Homoharringtonine) regimens, in conjunction with targeted drug therapy, did not achieve remission. Subsequently, the patients were shifted to the relapsed/refractory chemotherapy regimen C + HAG (Cladribine, Homoharringtonine, Cytarabine, and G-CSF) for two cycles, which also failed to induce remission. One patient underwent Haploidentical Hematopoietic Stem Cell Transplantation (Haplo-HSCT) and achieved complete molecular remission during a 12-month follow-up period. Regrettably, the other two patients, who did not receive transplantation, passed away. The therapeutic conclusion is that pediatric AML patients with the aforementioned co-expression do not respond to chemotherapy. Non-remission transplantation, supplemented with tailor-made pre- and post-transplant strategies, may enhance treatment outcomes.

Pattern of occupational lung disease among industrial workers attending a medical college of Eastern India

ABSTRACT Background: Occupational lung diseases (OLDs) contribute a significant proportion to the global burden of pulmonary morbidities but are grossly misdiagnosed due to the relative lack of attribution given to occupational exposures. Obstructive lung diseases are known to be associated with long-lasting disability and loss of earning capacity (LOEC) among workers in industrial setups, thus reducing nationwide productivity. Objective: In this context, the study aimed to find out the pattern of OLD and factors associated with the severity of it among patients in a tertiary care hospital. Materials and Methods: The study was a record-based secondary data analysis conducted in the Medical Records Department of a Medical College in Kolkata. A computerized database of patients attending Special Medical Board (SMB) examinations from the Department of Medical Records was utilized for data collection. A data abstraction format was constructed to collect information on pulmonary morbidity, occupational exposure, and sociodemographic and behavioral variables. Extracted data were analyzed in Microsoft Excel and Statistical Package for Social Sciences (SPSS) software Results: After a review of records, it was shown that 62.3% (66 out of 106 people) of the study subjects had an obstructive type of OLD, the most common being Jute Byssinosis. A negative correlation (Spearman’s ρ = -0.136) was found between pulmonary function (FEV1/FVC) and LOEC (%) in the study subjects. In the multivariable logistic regression, exposure to organic dust was found to be significantly associated with worsened lung function {adjusted-Odd’s Ratio (95% Confidence Interval) =3.11 (1.1–8.8), P value = 0.03}. Conclusion: OLD is an understated health issue, especially in an industrial diaspora of developing countries, like India. Healthcare facilities should utilize their resources properly for the advancement of medical surveillance in industries where organic dust is produced. Health education of the stakeholders regarding the consequences of OLDs and the benefits of preventive primary approaches will go a long way in alleviating the burden of disease.

Assessment of water, sanitation and hand hygiene practices in rural households of Tamil Nadu: A cross-sectional study

ABSTRACT Context: Water is a basic human right essential to all for sustainable development. Sanitation is one of the determinants of quality of life and the human development index. Drinking unsafe water impairs health through illnesses such as diarrhoea, and untreated excreta contaminates ground waters and surface waters used for drinking, bathing and household purposes. Aims: To assess the existing facilities and practices related to drinking water, sanitation, and hygiene among household members in the rural population of Tamil Nadu and to assess whether accessibility and availability of safe drinking water and adequate sanitation under sustainable development goal 6 is being achieved in the rural population of Tamil Nadu. Methodology: This community-based cross-sectional study was carried out among 200 households in the rural field practice area of the Medical College and Hospital, Thiruvallur district, Tamil Nadu. The participants were interviewed using a predesigned semi-structured questionnaire on their existing water, sanitation, and hand washing facilities and practices Results: Our study observed that 71.5% of households had piped water supply into their dwellings, 82% were using sanitary latrines and 28% had closed drainage for draining wastewater. Twenty-eight percent were using soap and water for hand-washing before food, and 82.5% were doing hand-washing with soap after using the toilet. In our study, the association between sanitary practices and education, occupation and socioeconomic status was statistically significant Conclusions: Our study emphasized the need for strengthening health education and behaviour change communication regarding sanitation and hand hygiene practices.
