Introduction: The occurrence of rotator cuff tendinopathy, which is invariably symptomatic, increases as populations age, being largely observed among patients with diabetes. The objective of the present study is to find out the occurrence of rotator cuff tendinopathy in elderly diabetic patients who were asymptomatic, composed of healthy individuals and those with diabetes mellitus. Materials and methods: The participants in this study included 87 elderly diabetic patients and 56 controls (mean age: 69.3±4.9 and 71.8±3.6, respectively), who were asymptomatic from shoulder. All patients, including, underwent shoulder MRI examination using 1.5 tesla MRI. Results: We recorded greater tendons thickness in the diabetic patients as compared with the controls (supraspinatus tendon: 6.6±0.7mm vs 5.3±0.8mm, p<0.001; biceps tendon: 3.9±0.7mm vs 3.1±0.8mm, p<0.002). Moreover, higher incidence of supraspinatus tendon tear was noted in diabetics as compared to biceps tendon (major tears: 32 (36.7%) vs 6 (10.7%), p=0.052; minor tears: 51 (58.6%) vs 11 (19.6%), p=0.032). Conclusions: The present study suggests that age-related rotator cuff tendinopathy is more prevalent among patients with diabetes. Therefore, MRI is an investigation of choice for early detection i.e., at pre-symptomatic stages of rotator cuff tendinopathy, as the patients may develop symptoms later. Keywords: asymptomatic

ObjectiveTo explore the mechanism by which Yinchenhao Tang intervenes in α-naphthylisothiocyanate （ANIT）-induced cholestatic liver injury by regulating the Takeda G-protein-coupled receptor 5（TGR5）/NOD-like receptor protein 3（NLRP3）/cysteine aspartate-specific protease-1 （Caspase-1） pyroptosis signaling pathway. MethodsForty male Wistar rats were randomly assigned into blank， model， ursodeoxycholic acid， and Yinchenhao Tang groups. Except the blank group， other groups were treated with ANIT dissolved in olive oil for the modeling of cholestatic liver injury. Ursodeoxycholic acid （0.1 g·kg^-1） and Yinchenhao Tang （9.23 g·kg^-1） were administered by gavage. The blank group and the model group were administrated with the same amount of pure water， once a day for 3 days. The blood and liver tissue samples were collected， and the serum levels of liver function indicators were measured by an automatic biochemical analyzer. Hematoxylin-eosin staining was employed to observe the pathological changes of the liver. The levels of interleukin （IL）-1β and IL-18 in the liver tissue were determined by ELISA. The mRNA levels of IL-1β， IL-18， TGR5， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， Caspase-1， and GSDMD in the liver tissue were assessed by Real-time PCR. The protein levels of TGR5， NLRP3， ASC， Caspase-1， and GSDMD in the liver tissue were determined by Western blot. ResultsCompared with the blank group， the model group showed elevated levels of alanine amino-transferase （ALT）， aspartate transferase （AST）， alkaline phosphatase （ALP）， total bile acid （TBA）， and total bilirubin （TBil） in the serum （P<0.01）， inflammatory cell infiltration， hepatocyte swelling， and bile duct epithelial cell proliferation in the liver， raised levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA and protein levels of TGR5 （P<0.01）， up-regulated mRNA levels of IL-18 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， IL-1β （P<0.05）， and NLRP3 （P<0.05）， and up-regulated protein levels of NLRP3 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， and GSDMD （P<0.05）. Compared with the model group， the ursodeoxycholic acid group showed declined levels of AST （P<0.01）， TBA （P<0.01）， TBil （P<0.01）， and ALT （P<0.05） in the serum， lowered levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA levels of NLRP3 （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， IL-1β （P<0.05）， IL-18 （P<0.05）， and ASC （P<0.05）， up-regulated mRNA and protein levels of TGR5 （P<0.05）， and down-regulated protein levels of NLRP3， ASC， Caspase-1， and GSDMD （P<0.05）. Compared with the model group， the Yinchenhao Tang group showed lowered levels of ALT， AST， ALP， TBA， and TBil in the serum （P<0.01）， declined levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA levels of IL-1β （P<0.01）， NLRP3 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， and IL-18 （P<0.05）， up-regulated mRNA and protein levels of TGR5 （P<0.01）， and down-regulated protein levels of Caspase-1 and GSDMD （P<0.05）. The liver tissue of the administration groups showed reduced infiltration of inflammatory cells， reduced swelling of hepatocytes， and alleviated proliferation of bile duct epithelial cells. ConclusionYinchenhao Tang can ameliorate ANIT-induced cholestatic liver injury by regulating the hepatocyte pyroptosis mediated by the TGR5/NLRP3/Caspase-1 signaling pathway.

Cholestatic liver injury refers to the bile production， secretion， and excretion disorder caused by various reasons. It induces liver injury， metabolic disorders， and dysfunction of the hepatobiliary system， which can further develop into liver fibrosis， cirrhosis， liver failure， and even death. At present， the preferred drug for clinical treatment is ursodeoxycholic acid， which， however， induces adverse reactions and is intolerant in some patients. Yinchenhao Tang is a representative prescription of traditional Chinese medicine for the treatment of jaundice due to Yang jaundice. It has the effects of clearing heat， eliminating dampness， and removing jaundice and has shown good therapeutic effect in long-term clinical application. Modern pharmacological studies have found that this prescription has anti-inflammatory， anti-oxidation， bile acid balance-regulating， hepatocyte apoptosis-inhibiting and other liver-protecting effects. This paper reviews the relevant clinical and animal experimental studies on Yinchenhao Tang in the treatment of cholestatic liver injury in recent years. Yinchenhao Tang can intervene in the progression of cholestatic liver injury by regulating bile acid metabolism and excretion， reducing inflammatory response， inhibiting oxidative stress， alleviating endoplasmic reticulum stress， inhibiting hepatocyte apoptosis， and protecting intestinal mucosal barrier. This paper systematically expounds the molecular mechanisms by which Yinchenhao Tang regulates cholestatic liver injury that are confirmed by current research， aiming to provide reference for the clinical application and in-depth study of Yinchenhao Tang.

Objective To analyze the clinical characteristics and risk factors of noninfectious fever after endovascular repair of aortic dilatation diseases, and to explore management strategies. Methods A retrospective analysis was conducted on the clinical data of patients who underwent endovascular aortic repair for aortic dilatation diseases from January 2021 to October 2023. Based on inclusion and exclusion criteria, the enrolled patients were divided into a febrile group and an afebrile group according to the presence of postoperative fever. Clinical data, including demographics and surgical details, were compared between the two groups. Multivariate logistic regression analysis was performed on indicators with P≤0.05 in the univariate analysis, and receiver operating characteristic (ROC) curves were generated to analyze the predictive value of risk factors for postoperative noninfectious fever. Results A total of 305 patients were included in the final analysis. Postoperative noninfectious fever occurred in 75.08% (229/305) of the patients, with 98.25% of cases occurring within the first two postoperative days. The febrile group (n=229) had a median age of 65.0 (IQR: 53.0, 73.0) years with 83.4% males, while the afebrile group (n=76) had a median age of 71.0 (IQR: 65.0, 76.7) years with 84.2% males. Univariate analysis showed that the age, prevalence of coronary heart disease, preoperative statin use, and prevalence of aortic aneurysm were significantly lower in the febrile group compared to the afebrile group. Logistic regression analysis indicated that age, surgical site, disease type, preoperative elevated body temperature, and stent type were significantly associated with noninfectious fever, while preoperative statin use was negatively correlated. ROC curve analysis demonstrated that age, surgical site, preoperative elevated body temperature, and stent type had significant predictive value for postoperative noninfectious fever (P<0.01). Conclusion Noninfectious fever is highly prevalent following aortic repair. The relationship between fever and infection should be comprehensively evaluated based on risk factors and changes in the patient's condition to promote the rational use of antibiotics.

Objective: This study aimed to demonstrate the benefits of using SaTScan (Boston, MA, USA), a cluster-detection software programme, and whole genome sequencing to investigate a suspected outbreak of Serratia marcescens infections in a tertiary government hospital in the southern Philippines. The hospital is part of the national Antimicrobial Resistance Surveillance Program’s network of sentinel sites. Methods: The investigation followed national outbreak investigation protocols. In May 2022, when evaluation of daily hospital laboratory census data revealed an increase in the number of Serratia species in the hospital, an alert was triggered. A concurrent, routine SaTScan analysis of the hospital’s surveillance data by the Antimicrobial Resistance Surveillance Reference Laboratory confirmed a cluster of cases. The Reference Laboratory requested isolates from clinical specimens from the hospital for confirmation of bacterial identification, antimicrobial susceptibility testing and whole genome sequencing. Results: Six isolates were submitted for genomic analysis, two of which were from the identified cluster. Although originally identified as S. marcescens, five of the isolates were subsequently confirmed as S. sarumanii. Phylogenetic analysis showed that the two isolates from the cluster were closely related and belonged to the same clade, which may suggest a common source. Three antimicrobial resistance genes were identified, but their phenotypic expression was limited, with one isolate exhibiting resistance mechanisms. Discussion: This study highlighted the utility of SaTScan for the early detection of potential disease outbreaks. The use of whole genome sequencing enhanced the investigation by enabling the analysis of potential transmission pathways at the genetic level, identification of the outbreak source and the detection of novel species.

Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P＞0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

Objective To integrate and analyze the disease burden of esophageal cancer caused by alcohol consumption in China from 1990 to 2019, along with the differences between genders, and predict the trends in disease burden changes from 2020 to 2029 to improve prevention and treatment strategies. Methods The disease burden of esophageal cancer caused by alcohol consumption in China from 1990 to 2019 was extracted and integrated from the 2019 Global Burden of Disease (GBD) database, and the corresponding trend was analyzed using the Joinpoint regression model with Joinpoint 4.9.1.0 software. The gray prediction model [GM (1, 1) ] was used to forecast the disease burden of alcohol-related esophageal cancer in China from 2020 to 2029. Results In 2019, the leading causes of esophageal cancer in China were tobacco, alcohol, high body mass index, and insufficient fruit and vegetable intake, accounting for the first to fifth positions in esophageal cancer deaths. From a gender perspective, in 2019, the death number and standardized mortality rate for males were 18.97 times and 20.00 times higher than for females, respectively. The disability-adjusted life years (DALYs) and standardized DALYs rate for males were 33.08 times and 24.78 times higher than those for females, respectively, indicating a heavier disease burden of alcohol-related esophageal cancer among Chinese males. From 1990 to 2019, the average annual percentage change (AAPC) in deaths and DALYs due to alcohol-related esophageal cancer in China was 2.08% and 1.63%, respectively, showing a continuous upward trend with statistical significance (P<0.05). The AAPC values for standardized mortality rate and standardized DALYs rate from 1990 to 2019 were –0.92% and –1.23%, respectively, showing a continuous downward trend with statistical significance (P<0.05). The population aged ≥55 years was the main group bearing the disease burden among all age groups from 1990 to 2019. The gray prediction model predicted that by 2029, the overall standardized mortality rate and standardized DALYs rate would decrease to 2.94/100 000and 67.94/100 000, with a greater decline in females than in males. Conclusion Over the past 30 years, the disease burden of alcohol-related esophageal cancer in China has slightly decreased. However, the reduction in disease burden is still lower compared to the overall decline in esophageal cancer burden, and the disease burden for males is significantly higher than for females. Focusing on prevention and treatment for males and the elderly population remains a major issue in addressing alcohol-related esophageal cancer in China.

BACKGROUND

Thyroid storm (TS) continues to be a diagnostic and therapeutic challenge. It is a life-threatening severe thyrotoxicosis characterized by organ decompensation. This study aims to determine if there are any changes in this present century about TS diagnosis and management. Furthermore, it aims to describe the clinical profile, precipitants, and outcomes of patients with TS seen at the University of Santo Tomas Hospital (USTH) and assess the association of patient characteristics with mortality.

This is a retrospective cohort analysis of patients with TS admitted at USTH from 2009 through 2018. Logistic regression analysis was used to determine the association of age, Burch Wartofsky-Point Scale (BWPS) score, clinical manifestations, and precipitating factor with mortality.

A total of 21 cases were identified. Majority of the patients were female (90.48%) with a mean age of 42.90 years old. The overall mean BWPS was 49.52 (16.35) while those who expired had higher mean score of 61.67 (5.77). TS as the first clinical presentation was seen in only one patient (4.7%) while majority were previously diagnosed with hyperthyroidism, (95.24%). Graves’ disease (90.48%) was the most common etiology of thyrotoxicosis. Cardiac manifestations were predominant and tachycardia was the most common clinical manifestation (80.95%) with thyrotoxic heart disease as a comorbidity (23.81%). The most common precipitant was infection (52.38%) followed by noncompliance with treatment. The mean hospital length of stay was four days with two patients needing intubation, and both expired afterward. There were three mortalities (14.29%) due to multiple organ dysfunction and fatal arrythmia.

TS remains a life-threatening condition. Aggressive treatment is justified once with suspicion of TS. Age, BWPS on admission, clinical manifestation and precipitants did not predict the likelihood of mortality. Since predictive features are still not thoroughly identified due to its infrequency, it remains for us to be vigilant and not delay crucial treatment to improve the morbidity and mortality associated with TS.

BACKGROUND

The Philippines has been significantly affected by the HIV epidemic in the Asia-Pacific region, with a notable increase in new cases over the past decade. Despite efforts to promote HIV testing, access to treatment, and awareness campaigns, progress has been slow, particularly among youths. Tangere, a market research application, conducted surveys during and after the COVID-19 pandemic to assess HIV knowledge among Filipinos.

This study aimed to evaluate changes in HIV awareness among young Filipinos during and after the COVID-19 pandemic using data collected via Tangere’s surveys. Specifically, it sought to analyze demographic characteristics, sources of HIV information, and knowledge regarding HIV transmission, prevention, and stigma.

Tangere collaborated with the investigators to develop a questionnaire assessing HIV knowledge among young Filipinos. Surveys were conducted during and after the COVID-19 pandemic, targeting subscribers aged 18-35 years, primarily from the National Capital Region and Luzon area. Data analysis involved calculating frequencies and percentages to summarize demographic characteristics and HIV knowledge. An Independent-Samples Proportions procedure was used to compare HIV knowledge during and after the pandemic.

The survey revealed that while respondents generally possessed reasonable knowledge about HIV, there were notable changes in the awareness during and after the pandemic. Social media and television were identified as primary sources of HIV information. Knowledge regarding HIV transmission and prevention increased postpandemic, particularly concerning preventive measures such as pre-exposure prophylaxis (PREP) and motherto-child transmission (MTCT). However, persistent misconceptions and stigma surrounding HIV remained, indicating the need for continued education and advocacy efforts.

The study underscores the importance of utilizing social media platforms for HIV awareness campaigns, especially among youths who are disproportionately affected by the epidemic. Despite improvements in knowledge, the Philippines has yet to achieve global HIV prevention goals. Continued efforts to enhance awareness, particularly regarding recent advancements in HIV prevention and treatment, are essential for curbing the epidemic and improving public health outcomes nationwide.

BACKGROUND

Due to the COVID-19 outbreak, schools had to switch online. The sudden transition to blended teaching and learning (BTL) poses challenges for students and teachers, especially for health science programs that require hands-on practical experience. The validity, reliability, and responsiveness of these self-report questionnaires (SRQs) should be established to ensure the accuracy of the results as intended by the SRQ.

This study critically appraised, compared, and summarized the psychometric properties of SRQ evaluating BTL among health science university students. This review determined the SRQ’s reliability, internal consistency, various forms of validity (content, criterion, construct), and responsiveness.

Following a 10-step procedure based on COSMIN guidelines, we conducted a systematic review of SRQs used by health science university students to evaluate blended teaching and learning. Studies were eligible if they reported psychometric properties of SRQs related to blended learning among university health science students; exclusions included studies focusing on perceptions, attitudes, self-efficacy, and satisfaction, as well as articles such as biographies, editorials, and conference materials. Searches covered multiple electronic databases until April 26, 2023, including PubMed, EMBASE, Web of Science, MEDLINE (OVID), PsycInfo, CINAHL, EBSCOHOST, ERIC, Scopus, Science Direct, Google Scholar, JSTOR, Acta Medica Philippina, Philippine Journal of Health Research and Development, and HERDIN, managed through Zotero. Two independent reviewers performed database searches, title and abstract screening, and full-text evaluations, with a third reviewer resolving any disputes. The COSMIN Risk of Bias Checklist was employed to evaluate included studies on the development and various measurement properties of SRQs. The reviewers assessed SRQ standards, including validity, reliability, internal consistency, measurement error, responsiveness, interpretability, and feasibility. Data extraction and result tabulation were independently completed, with content comparison by two health education experts. This evaluation categorized the SRQs into three quality and validity levels.

The study examined five articles; four were rated as 'doubtful' and one as 'inadequate' in the overall development of SRQ. All four 'doubtful' studies demonstrated questionable content validity when university students were asked about the questionnaire's relevance, comprehensiveness, and comprehensibility. Only half of these studies achieved an 'adequate' rating for content validity based on expert opinions on relevance and comprehensiveness. All but one study scored from 'very good' to 'adequate' in structural validity. Three out of the four studies scored a very good rating for internal consistency, while one was deemed 'inadequate' in internal consistency, cross-cultural validity, and reliability. Three out of four studies scored 'very good' on construct validity, but all overlooked criterion validity and responsiveness. Conducted in various locations, including Australia, Romania, Turkey, and Taiwan, these studies highlighted both common characteristics and limitations in questionnaire development according to the COSMIN guidelines. Four studies were deemed reliable and valid for BTL constructs (Category A); Wu et al. requires further validation (Category B). Study limitations included heterogeneity in populations, settings, and questionnaire versions, potential subjective bias in SRQ content comparison, and the evolving nature of SRQs in blended learning contexts.

The systematic review reports the development and evaluation of SRQs for BTL while identifying gaps in their applicability to health science programs. The Blended Learning Scale (BLS) of Lazar et al. and the Blended Learning Questionnaire (BLQ) of Ballouk et al. showed an ‘adequate' rating for content validity. BLS revealed very good structural validity, internal consistency, and adequate content validation. Although the BLQ lacked Confirmatory Factor Analysis, it yielded valuable constructs for evaluating health sciences students' experiences in BTL. Both tools require improvements on recall period, completion time, interpretability, and feasibility. The review underscores the necessity for cont inuous assessment and enhancement of such instruments in BTL, advocating a rigorous scale development process. Furthermore, it encourages the customization of teaching and learning evaluation tools to suit specific institutional contexts while promoting further validation of these questionnaires across different populations in future research.
