Neurospine 2024;21(4):1053-1065
Objective:
To analyze the predictive factors for neck pain and cervical spine function after laminoplasty for degenerative cervical myelopathy (DCM) using K-means for longitudinal data (KML).
Methods:
In this prospective cohort study, we collected clinical and radiographic data from patients with DCM who underwent cervical laminoplasty. A novel index of surgical outcome, “neck function,” which comprises neck pain and cervical spine function according to the Japanese Orthopedic Association Cervical Myelopathy Evaluation Questionnaire, was proposed. We treated surgical outcomes as longitudinal rather than cross-sectional data and used KML for analysis. Patients were categorized as having good or poor outcomes based on the KML graph of neck pain and cervical spine function.
Results:
From 2016 to 2020, 104 patients underwent laminoplasty for DCM; however, 35 patients were excluded because of loss to follow-up or incomplete data. The authors found that central canal stenosis (odds ratio [OR], 17.93; 95% confidence interval [CI], 1.26–254.73; p=0.03) and preoperative neck pain (OR per 1 point increase=1.49; 95% CI, 1.12–1.99; p=0.006) were 2 negative predictive factors and that a positive K-line during flexion was a positive predictive factor (OR, 0.11; 95% CI, 0.01–0.87; p=0.036) for neck function after laminoplasty.
Conclusion
Central canal stenosis, preoperative neck pain and a K-line during flexion were found to be predictive of postoperative neck pain and cervical spine function after laminoplasty. To achieve better surgical outcomes for neck function, the authors suggest the utilization of these determinants as a guiding framework for the selection of surgical approaches for DCM.

PURPOSE: The proposed Men's Health Index (MHI) aims to provide a practical and systematic framework for comprehensively assessing and stratifying older men with the intention of optimising their health and functional status. MATERIALS AND METHODS: A literature search was conducted using PubMed from 1980 to 2012. We specifically looked for instruments which: assess men's health, frailty and fitness; predict life expectancy, mortality and morbidities. The instruments were assessed by the researchers who then agreed on the tools to be included in the MHI. When there was disagreements, the researchers discussed and reached a consensus guided by the principle that the MHI could be used in the primary care setting targetting men aged 55-65 years. RESULTS: The instruments chosen include the Charlson's Combined Comorbidity-Age Index; the International Index of Erectile Function-5; the International Prostate Symptom Score; the Androgen Deficiency in Aging Male; the Survey of Health, Ageing and Retirement in Europe Frailty Instrument; the Sitting-Rising Test; the Senior Fitness Test; the Fitness Assessment Score; and the Depression Anxiety Stress Scale-21. A pilot test on eight men was carried out and showed that the men's health index is viable. CONCLUSIONS: The concept of assessing, stratifying, and optimizing men's health should be incorporated into routine health care, and this can be implemented by using the MHI. This index is particularly useful to primary care physicians who are in a strategic position to engage men at the peri-retirement age in a conversation about their life goals based on their current and predicted health status.

Introduction: Cardiovascular diseases are the main cause of
morbidity and mortality in Malaysia. There is evidence of
high traditional and complementary medicine (TCM) use
among population with cardiovascular risk and there have
been anecdotal reports about substitution of conventional
medicines with TCM. We investigated the prevalence of TCM
use, treatment preference and substitution of conventional
medicines in study population with cardiovascular risk
factors in Pahang, Malaysia.
Methods: A cross-sectional survey was conducted using an
interviewer-administered questionnaire in five districts of
Pahang. A total of 1250 households were chosen through
proportionate and systematic sampling. Respondents aged
18 years and above were selected.
Results: The study population with cardiovascular risk
factors who used TCM was higher than the general
population (31.7% versus 25.9%). There were no clear
preferences in using TCM by gender, age groups,
educational level and income even though other
bumiputeras showed a slight inclination towards TCM use.
Among the study population with cardiovascular risk
factors who consumed TCM, 20-30% of them were using
TCM as a substitute for their conventional medications.
Respondents from the younger age group (18-40 years)
(57.1%), highest educational level (43.2%), other
bumiputeras (38.4%) and highest income group (31.4%)
preferred the combination of both conventional and
traditional medicine.
Conclusion: TCM use among population with cardiovascular
risk factors is high. The high preference for combination
therapy of TCM and conventional medications among young
adults and the use of TCM to substitute conventional
medications show that much research is needed to provide
proven TCM therapies to avoid self-mismanagement of
cardiovascular risk in Malaysia.

Journal of Breast Cancer 2024;27(3):187-200
Purpose:
Pencil-beam scanning (PBS) is a modern delivery technique used in proton beam therapy (PBT) to reduce normal tissue reactions. No dosimetric correlation between dermatitis and PBS has been reported for breast cancer. The current study aimed to investigate the factors associated with grade 2 or higher dermatitis in patients with breast cancer undergoing PBT using PBS.
Methods:
The medical data of 42 patients with breast cancer who underwent adjuvant radiotherapy between December 2019 and September 2023 were reviewed. All patients received hypofractionated radiotherapy (HFRT), either 26 Gy (relative biological effectiveness [RBE])/five fractions or 40.05 or 43.5 Gy (RBE)/15 fractions, for the whole breast/chest wall with or without nodal irradiation. The duration of acute radiation dermatitis was defined as within 90 days from the start of radiotherapy. The Kaplan–Meier method and Cox proportional hazards model were used for univariate and multivariate analyses of the actuarial rates of grade 2–3 dermatitis.
Results:
Twenty-two (52.4%) and 20 (47.6%) patients were diagnosed with grade 1 and 2 dermatitis, respectively. Multivariate analysis revealed a clinical target volume (CTV) ≥ of 320 cc (p = 0.035) and a skin dose of D 10cc ≥ 38.3 Gy (RBE) (p = 0.009) as independent factors of grade 2 dermatitis. The 10-week cumulative grade 2 dermatitis rates were 88.2%, 39.4%, and 8.3% (p < 0.001) for patients with both high, either high, and neither high CTV and D 10cc , respectively.
Conclusion
To the best of our knowledge, this is the first study on dosimetric correlations for dermatitis in patients with breast cancer who underwent hypofractionated PBT using PBS. In the era of HFRT, skin dose modulation using PBS may reduce the incidence of dermatitis.

INTRODUCTIONThe implementation of competency-based internal medicine (IM) residency programme that focused on the assurance of a set of 6 Accreditation Council for Graduate Medical Education (ACGME) core competencies in Singapore marked a dramatic departure from the traditional process-based curriculum. The transition ignited debates within the local IM community about the relative merits of the traditional versus competency-based models of medical education, as well as the feasibility of locally implementing a training structure that originated from a very different healthcare landscape. At the same time, it provided a setting for a natural experiment on how a rapid integration of 2 different training models could be achieved.
MATERIALS AND METHODSOur department reconciled the conflicts by systematically examining the existing training structure and critically evaluating the 2 educational models to develop a new training curriculum aligned with institutional mission values, national healthcare priorities and ACGME-International (ACGME-I) requirements.
RESULTSGraduate outcomes were conceptualised as competencies that were grouped into 3 broad areas: personal attributes, interaction with practice environment, and integration. These became the blueprint to guide curricular design and achieve alignment between outcomes, learning activities and assessments. The result was a novel competency-based IM residency programme that retained the strengths of the traditional training model and integrated the competencies with institutional values and the unique local practice environment.
CONCLUSIONWe had learned from this unique experience that when 2 very different models of medical education clashed, the outcome may not be mere conflict resolution but also effective consolidation and transformation.
