The field of onco-microbiome is rapidly expanding. Multiple studies have shown the crucial role of gut microbiota in the regulation of nutrient metabolism, immunomodulation and protection against pathogens. Tools for manipulating the gut microbiota include dietary modification and faecal microbiota transfer. Accumulating evidence has also documented the application of specific intestinal microbiome in cancer immunotherapy, notably in enhancing the efficacy of immune checkpoint inhibitors. The aim of this review is to focus on the East Asian microbiome and to provide a current overview of microbiome science and its clinical application in cancer biology and immunotherapy.

BACKGROUND
This first clinical practice guideline (CPG) on osteoporosis prevention and management in the Philippines is the output of a shared undertaking by a multidisciplinary CPG development team spearheaded by the Osteoporosis Society of the Philippines Foundation, Inc. and joined by the Philippine Academy of Family Physicians; the Philippine College of Endocrinology, Diabetes, and Metabolism; the Philippine Orthopedic Association; the Philippine Obstetrics and Gynecological Society and the Philippine Rheumatology Association. This guideline seeks to augment and update the "Consensus statements on osteoporosis diagnosis, prevention and management in the Philippines," initially published in 2011, incorporating evidence-based practices developed in the last decade.
METHODOLOGYThe steering committee formulated and prioritized clinical questions based on meetings and stakeholder consultations. A PICO (population, intervention, comparator, outcome) format was used to develop clinical questions and guide the systematic search for evidence. The development of guidelines followed the ADAPTE process. Once completed, panel discussions were done using the Evidence to Decision Framework. After the panel discussions, the final recommendations were revised.
RESULTSThirty-four recommendations were formulated to address 27 clinical questions related to screening, prevention, diagnosis, pharmacologic and nonpharmacologic treatment, surgical management, follow-up, and continuity of care. With these recommendations, the developers aim to establish a standard of care in the prevention, diagnosis and management of osteoporosis and fragility fractures in both in-patient and out-patient cases that are appropriate to the Philippine context. Specifically, the CPG development group aims to use these recommendations to define the standard of care for osteoporosis as part of universal healthcare services once the program is implemented nationally. Relevant stakeholders may also use the recommendations to inform public and private payor policies for patients with fragility fractures, as well as by local government units or private companies looking to establish orthogeriatric centers with fracture liaison services.
CONCLUSIONThis guideline is helpful for physicians and other allied health personnel in screening, diagnosis, management and prevention of primary osteoporosis and fragility fractures among postmenopausal women and older men.

Osteoporosis and Sarcopenia 2024;10(3):114-118
Objectives:
This study aimed to investigate the relationships of foot and leg symptoms, structure, and function with functional limitations and osteoarthritis (OA).
Methods:
We included 1253 participants (mean age 58.1 years) from the Hong Kong Osteoporosis Study who completed an examination on foot posture, function, pain, and presence of deformities such as hallux valgus and varus knee. Using logistic regression, we estimated cross-sectional associations of each foot and knee problem with functional outcomes (slow walking speed, self-reported falls, and functional limitations) and OA. Through linkage to electronic health records, we further examined their associations with incident OA over 8 years using Cox models. All models were adjusted for age, sex, and body mass index.
Results:
The prevalence of hallux valgus, foot pain, and varus knee were 33.1%, 35.1%, and 25.8%, respectively.Planus foot posture was associated with varus knee, and pronated foot function was associated with hallux valgus. Of the assessed foot problems, only foot pain showed significant associations with functional outcomes, including functional limitations and recurrent falls. Foot pain was also associated with prevalent OA at baseline but not incident OA. Meanwhile, we observed a 3-times increased risk of incident OA associated with varus knee (95% CI = 1.48–6.10), and this association was particularly seen in older adults, women, and obese individuals.
Conclusions
In community-dwelling Chinese adults, foot pain, but not the reported foot deformities, is associated with functional limitations and falls, while varus knee is associated with incident OA.

INTRODUCTION:
Pleural infections are a significant cause of mortality. Intrapleural fibrinolytic therapy (IPFT) utilising alteplase and dornase is a treatment option for patients unsuitable for surgery. The optimal dose of alteplase is unknown, and factors affecting treatment success in an Asian population are unclear. We sought to determine the factors affecting treatment success in Tan Tock Seng Hospital, Singapore and evaluate the efficacy of lower doses of IPFT.
METHOD:
A retrospective analysis of patients with pleural infections treated with IPFT between July 2016 and November 2023 was performed. Treatment success was defined as survival without surgery at 3 months. Data, including patient demographics; comorbidities; RAPID (renal, age, purulence, infection source and dietary factor) scores; and radiological characteristics, were extracted from medical records and analysed. Linear mixed effects model and logistic regression were performed to determine factors affecting treatment success.
RESULTS:
A total of 131 cases were analysed. Of these, 51 (38.9%) reported positive pleural fluid culture, and the most common organism was Streptoccocus anginosus. Mean age was 65 years (standard deviation [SD] 15.5). Mean time from chest tube insertion to first dose of IPFT was 10.2 days (SD 11.5). Median starting dose of alteplase was 5 mg. Treatment success was reported in 112 cases (85.5%). There were no significant differences between the alteplase dose and radiological clearance. Patient age (odds ratio [OR] 0.94, confidence interval [CI] 0.89-0.98) and interval between chest tube insertion to first dose (OR 0.95, CI 0.91-0.99) were statistically significant variables for the treatment success.
CONCLUSION
Lower starting doses of alteplase remain effective in the treatment of pleural infection. Early IPFT may result in better outcomes.

INTRODUCTION:
The growing years are paramount for bone growth and mineral accrual. Children with long-term neurological condition (LTNC) have multiple risk factors for poor bone health and fragility fractures. In Singapore, this has not been studied systematically. Therefore, we aimed to evaluate the risk factors associated with fragility fractures in children with LTNC.
METHODS:
In this study, the search for fragility fractures was done by a retrospective review of patients with LTNC on follow-up in the paediatric neurology clinic and patients who presented with fracture to the paediatric orthopaedic clinic. Information on patients' demographics, medical history, intervention, biochemical bone markers and fracture history was collected.
RESULTS:
In a tertiary clinic population of 136 patients with LTNC, 65% were dependent on mobility (Gross Motor Function Classification System [GMFCS] V), 60% were underweight and 60% were fed via gastrostomy or nasogastric tube, or were on oral pureed diet. Furthermore, 60% were on anticonvulsants. The fracture rate was 3% in this population and was associated with low-impact activities such as transfer and dressing. Only 7.4% and 33% of the patients had undergone measurements of vitamin D and calcium levels, respectively.
CONCLUSION
The local prevalence of fragility fractures in children with LTNC on follow-up at the neurology clinic was found to be 3%. Risk factors identified were limited ambulation and compromised nutritional status associated with feeding difficulty. Recommendations to optimise bone health in children with LTNC were made. These include promoting weight-bearing activities, looking out for underweight children, avoiding vitamin D deficiency and ensuring adequate calcium intake.

Background and Objectives:
We compared real-world clinical outcomes of patients receiving intravascular lithotripsy (IVL) versus rotational atherectomy (RA) for heavily calcified coronary lesions.
Methods:
Fifty-three patients who received IVL from January 2017 to July 2020 were retrospectively compared to 271 patients who received RA from January 2017 to December 2018.Primary endpoints were in-hospital and 30-day major adverse cardiovascular events (MACE).
Results:
IVL patients had a higher prevalence of acute coronary syndrome (56.6% vs 24.4, p<0.001), multivessel disease (96.2% vs 73.3%, p<0.001) and emergency procedures (17.0% vs 2.2%, p<0.001) compared to RA. In-hospital MACE (11.3% vs 5.9%, p=0.152), MI (7.5% vs 3.3%, p=0.152), and mortality (5.7% vs 3.0%, p=0.319) were not statistically significant. 30-day MACE was higher in the IVL cohort vs RA (17.0% vs 7.4%, p=0.035). Propensity score adjusted regression using IVL was also performed on in-hospital MACE (odds ratio [OR], 1.677; 95% confidence interval [CI], 0.588–4.779) and 30-day MACE (OR, 1.910; 95% CI, 0.774–4.718).
Conclusions
These findings represent our initial IVL experience in a high-risk, real-world cohort. Although the event rate in the IVL arm was numerically higher compared to RA, the small numbers and retrospective nature of this study preclude definitive conclusions. Theseclinical outcomes are likely to improve with greater experience and better case selection, allowing IVL to effectively treat complex calcified coronary lesions.

12 weeks) were 81.8%, 50.0%, and 55.1% for DFD, and 68.8%, 50.0%, and 40.0% for SFED. Response based on age ( < 6, 6–12, and >12 years) were 59.3%, 42.9%, and 67.5% for DFD, and 36.4%, 58.8%, and 72.7% for SFED. In patients treated with DFD, concomitant proton pump inhibitor (PPI) administration resulted in improved outcomes (p=0.0177). Bivariate regression analysis showed that PPI with diet is the only predictor of response (p=0.0491), however, there were no significant predictors on multiple regression analysis.CONCLUSION: DFD and SFED are effective first line therapies for EoE. DFD should be tried first before extensive elimination diets. Concomitant therapy with PPI's may be helpful.]]>

BACKGROUND:
Recent findings on emergency department (ED) patient experience surveys and concerns for the low response rates challenge the quality and reliability of the survey reports. We assessed the consistency of an ED patient experience survey report and identified the effects of patient demographics on ED patient experiences.
METHODS:
We conducted a prospective, cross-sectional study at a university-based ED from July to December 2017. We obtained ED patient experience scores from an institutional version (IS) survey and the Press Ganey Associates-distributed survey (PGA). We compared top box scores from the two reports using frequency analysis and performed multivariable logistic regressions to identify associations between IS patient demographics and scores.
RESULTS:
We obtained 289 PGA and 234 IS responses. The IS reported significant, higher top box scores in doctor-specific patient questions compared to PGA (all four P-values < 0.01). Female, Christian and White patients were more likely to give top box scores (OR 3.07, OR 2.22 and OR 2.41, P-value < 0.05, respectively).
CONCLUSION
We found significant differences in ED patient experience scores between the IS and PGA surveys. We recommend that healthcare providers consider patient demographic variables when interpreting ED experience score reports. Multiple survey techniques and distribution methods may be adopted to best capture ED patient experiences.

BACKGROUNDIdentification of hospitalized carbapenem-resistant Enterobacteriaceae (CRE)-positive patient is important in preventing nosocomial transmission. The objective of this study was to illustrate the implementation of proactive infection control measures in preventing nosocomial transmission of CRE in a healthcare region of over 3200 beds in Hong Kong between October 1, 2010 and December 31, 2011.
METHODSThe program included active surveillance culture in patients with history of medical tourism with hospitalization and surgical operation outside Hong Kong within 12 months before admission, and "added test" as an opportunistic CRE screening in all fecal specimens submitted to the laboratory. Outbreak investigation and contact tracing were conducted for CRE-positive patients. Serial quantitative culture was performed on CRE-positive patients and the duration of fecal carriage of CRE was analyzed.
RESULTSDuring the study period, a total of 6533 patients were screened for CRE, of which 76 patients were positive (10 from active surveillance culture, 65 from "added test", and 1 secondary case from contact tracing of 223 patients with no nosocomial outbreak), resulting in an overall rate of CRE fecal carriage of 1.2%. The median time of fecal carriage of CRE was 43 days (range, 13-119 days). Beta-lactam-beta-lactamase-inhibitors, cephalosporins, and fluoroquinolones were associated significantly with high fecal bacterial load when used 90 days before CRE detection, while use of cephalosporins, carbapenems, and fluoroquinolones after CRE detection are significantly associated with longer duration of carriage. The duration of fecal carriage of CRE also correlates significantly with the initial fecal bacterial load (Pearson correlation: 0.53; P = 0.02).
CONCLUSIONProactive infection control measures by enhanced surveillance program identify CRE-positive patients and data obtained are useful for the planning of and resource allocation for CRE control.
