INTRODUCTION:
Conservative kidney management (CKM) is a recognised treatment option for selected patients with chronic kidney disease stage 5 (CKD G5), but prognostic indicators for mortality and optimal timing for palliative care transition remain uncertain.
METHOD:
This is a single-centre, prospective cohort study of CKD G5 patients who opted for CKM, conducted between April 2021 and September 2024, with longitudinal monitoring of Edmonton Symptom Assessment System Revised: Renal; Palliative Perfor-mance Scale (PPS); Resources Utilisation Group.Activities of Daily Living (RUG-ADL) scale; Clinical Frailty Score; Karnofsky Performance Score; and clinical and laboratory data. Primary outcomes included identifying baseline mortality predictors and validating the PPS for survival estimation. Cox proportional hazards models were used to identify independent predictors of mortality.
RESULTS:
Among 109 patients (mean age 79.8±7.3 years, 64.2% female), 62 (56.9%) died during follow-up. Multivariate analysis identified baseline estimated glomerular filtration rate (eGFR) (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.08.1.68, P<0.01) and serum albumin (HR 1.24, 95% CI 1.08.1.43, P<0.01) as predictors of 1-year mortality. Median survival varied by eGFR: 3.0 months (95% CI 0.6.2) for eGFR .5 mL/min/1.73 m2, 13.0 months (95% CI 9.1.16.9) for eGFR 6.10 mL/ min/1.73 m2, and 20.0 months (95% CI 16.5.23.5) for eGFR >10 mL/min/1.73 m2 (P<0.01). Subsequent PPS correlated strongly with survival, with median survival of 1.8 months for PPS <50, 5.3 months for PPS 50.60, and 7.9 months for PPS 70.80 (P=0.03).
CONCLUSION
Baseline eGFR and serum albumin predict 1-year mortality in CKM patients. PPS offers a practical tool for identifying patients requiring palliative care transition, supporting personalised care pathways and timely integration of palliative care.

The current standard treatment for muscularis propria-invasive (T2) colorectal cancer is surgical colectomy with lymph node dissection. With the advent of new endoscopic resection techniques, such as endoscopic full-thickness resection or endoscopic intermuscular dissection, T2 colorectal cancer, with metastasis to 20%-25% of the dissected lymph nodes, may be the next candidate for endoscopic resection following submucosal-invasive (T1) colorectal cancer. We present a novel endoscopic treatment strategy for T2 colorectal cancer and suggest further study to establish evidence on oncologic and endoscopic technical safety for its clinical implementation.

Submucosal invasive (T1) colorectal cancer is a significant clinical management challenge, with an estimated 10% of patients developing extraintestinal lymph node metastasis. This condition necessitates surgical resection along with lymph node dissection to achieve a curative outcome. Thus, the precise preoperative assessment of lymph node metastasis risk is crucial to guide treatment decisions after endoscopic resection. Contemporary clinical guidelines strive to identify a low-risk cohort for whom endoscopic resection will suffice, applying stringent criteria to maximize patient safety. Those failing to meet these criteria are often recommended for surgical resection, with its associated mortality risks although it may still include patients with a low risk of metastasis. In the quest to enhance the precision of preoperative lymph node metastasis risk prediction, innovative models leveraging artificial intelligence or nomograms are being developed. Nevertheless, the debate over the ideal sensitivity and specificity for such models persists, with no consensus on target metrics. This review puts forth postoperative mortality rates as a practical benchmark for the sensitivity of predictive models. We underscore the importance of this method and advocate for research to amass data on surgical mortality in T1 colorectal cancer. Establishing specific benchmarks for predictive accuracy in lymph node metastasis risk assessment will hopefully optimize the treatment of T1 colorectal cancer.

Purpose:
To investigate the effect of androgen deprivation therapy (ADT) on health-related quality of life (HRQOL) in Asian men with all stages of prostate cancer.
Materials and Methods:
READT (real-life evaluation of the effect of ADT in prostate cancer patients in Asia) was a multi-center, prospective observational study involving six sites across four Asian populations. We enrolled eligible prostate cancer patients, who opted for ADT alone or in combination without prior neoadjuvant or adjuvant ADT within 12 months. The EuroQoL-5 dimensions, 5 level scale (EQ-5D-5L) utility index scores and visual analog scale (VAS) were evaluated at baseline, month 6 and month 12.
Results:
A total of 504 patients were recruited into READT between September 2016 and May 2020 with 52.9% diagnosed with metastatic prostate cancer. The EQ-5D-5L was evaluable in 442/504 (87.7%) of patients. Overall baseline EQ-5D-5L utility index score was 0.924 (interquartile range [IQR] 0.876–1.000). We observed a statistically significant difference in baseline EQ-5D-5L utility index score among different populations with a median EQ-5D-5L utility index score of 1 for Taiwan & Hong Kong, 0.897 for China and 0.838 for Malaysia. Similar trend was observed throughout multiple treatment time-points. Stage IV prostate cancer were significantly associated with a lower baseline EQ-5D-5L utility index score compared to stage I–III prostate cancer, producing a median disutility value of -0.080. Participants had a high median VAS (80, IQR 70–90), indicating good overall health on average during ADT initiation.
Conclusions
The study highlights the differences in health state utility index scores among various Asian prostate cancer patients receiving ADT at real-world setting. Our findings will be informative and useful in cost-effectiveness evaluation and policy decision making.

Work can guarantee financial stability and quality of life, foster identity and self-confidence and ensure social wellbeing. Thus, it is vital to understand the motivation and intention to work. The theory of planned behaviour (TPB) has
been used extensively in theory and research in a wide range of human behaviours. However, research on the efficacy
of the TPB in the vocational realm remains limited. This study aims to review the applications of the TPB in work-related
intention. Relevant studies were systematically searched using standardised keywords across two databases. Three
hundred and sixty-six research articles (n=366) were identified, however, only seven articles (n=7) were eligible to be
evaluated in this study using the Assessment for Cross-Sectional Studies (AXIS) tool. All studies confirmed the efficacy
of the TPB in explaining work intentions. The explained variance in intention varied from 10% (post-retirement work
intention) to 59% (to work with older adults). However, the underlying core constructs of TPB namely attitudes, subjective
norms, and perceived behavioural control (PBC) do not always altogether consistently predict the intention to work.
Besides, few review studies have reported variables that are not included in TPB, such as moral obligation, identity, and
tenure, which contributed to a significant amount of variance in intention. Overall, the findings of this review indicated
that TPB is helpful in understanding work intention. However, further investigation is needed to estimate the extended
variables’ performance in explaining intentions and to cover a broader aspect of work intentions.

Pindborg tumour or calcifying epithelial odontogenic tumour (CEOT) is a rare, slow-growing benign tumour occurring most frequently in the posterior part of the mandibular arch. Management ranges from simple enucleation to a segmental resection of the mandible. The latter compromises the jaw foundation for any future prosthetic rehabilitation and warrants jaw reconstruction procedures to improve the retention and stability of the prosthesis. Using mini-implants in such compromised situations is a minimally invasive and cost-effective aid compared to conventional implants. The present case report documents the prosthetic rehabilitation of a patient who underwent mandibular resection for a Pindborg tumour using mini-implants.

The mass vaccination against COVID-19 has saved millions of lives globally. The majority of people experience short-term mild side effects; however, in rare cases, some develop long-term severe adverse events. This case report illustrates the case of a middle-aged man with Parsonage–Turner syndrome, a rare adverse event following COVID-19 immunisation. The patient presented with pain and weakness of the right upper arm for 2 months, which developed 5 days after he received his mRNA COVID-19 booster vaccine. He sought medical attention after 9 weeks of experiencing weakness with obvious muscle wasting. He reported his condition only via a phone application, as he thought that his condition was self-limiting and will improve with time. Herein, we discuss the syndrome and highlight the importance of patient education and early recognition of serious adverse events related to vaccinations in the primary care setting.

Objective: To elucidate the cytotoxic effect of the secondary metabolites of Barrientosiimonas humi (B. humi) on MCF-7 and MDA-MB-231 human breast cancer cells and its underlying mechanisms of action. Methods: The extract was obtained from the fermentation of B. humi and fractionation of the crude extract was conducted via column chromatography. Cytotoxicity of the B. humi extract was determined by using MTT assay and real-time cellular analysis. Morphological changes, cell cycle profiles, mode of cell death, and caspase expressions of control and treated breast cancer cells were determined. Results: The ethyl acetate extract isolated from B. humi was cytotoxic against MCF-7 and MDA-MB-231 cell lines. One of the dichloromethane (DCM) fractions, designated as DCM-F2, exhibited the strongest activity among all the fractions and thereby was selected for further studies. DCM-F2 had selective cytotoxicity on target cells by inducing apoptosis, particularly in the early stage, and cell cycle arrest. Treated cells caused inhibition of cell cycle progression at 72 h leading to a significant increase (P < 0.05) in the G0/G1 population. DCM-F2 treated MDA-MB-231 cells showed caspase-dependent apoptosis, whereas DCM-F2 treated MCF-7 cells showed a caspase-independent apoptosis pathway. Five compounds were successfully isolated from B. humi. Cyclo (Pro-Tyr) was the most cytotoxic and selective compound against MCF-7 cells. Conclusions: B. humi ethyl acetate extract exhibits significant cytotoxicity against MCF-7 and MDA-MB-231 cells via induction of apoptosis and cell cycle arrest.

Purpose:
Anastomotic leakage (AL) is the anathema of colorectal surgery. Its occurrence leads to increased morbidity and mortality and a prolonged hospital stay. Much work has gone into studying various biomarkers in drain fluid to facilitate early detection of AL. This stage 2a development study aims to assess the safety and feasibility of reliably detecting the iodine in Gastrografin (GG; Bayer Australia Ltd.) in drain fluid and stool samples by dual-energy computed tomography (DECT).
Methods:
This is a prospective, observational, controlled, consecutive cohort study establishing the safety and feasibility of the detection of GG in surgical drain fluid and stool as a biomarker of AL when patients with a low pelvic colorectal anastomosis undergo luminal flushing of the rectal tube with GG.
Results:
Ten consecutive patients were allocated to the saline flush group and the following 10 to the GG flush group. Three patients in the saline flush group developed an AL. One patient in the GG flush group developed an AL. An elevation in the drain fluid GG was detected using DECT on the day of clinical deterioration. None of the patients in the control group were found to have a positive result on DECT.
Conclusion
This study demonstrates the safety of a novel approach to the early detection of AL from extraperitoneal colorectal anastomoses. The technique requires validation in a larger cohort and a multicenter study is planned to investigate the efficacy of GG rectal tube flushes as an early biomarker of AL in low pelvic anastomoses.
