    BACKGROUND: Physical and pathological changes associated with advancing age affect sexual behaviours of the elderly. The aim of this study was to explore the impact of gender on sexual problems and perceptions among the urban Malay elderly.

    METHODS: A cross-sectional study was conducted among 160 Malaysian elderly participants aged 60 years and older who live in Kuala Lumpur. Twelve neighbourhood associations were randomly selected using multi-stage cluster sampling. Data was collected using standardized and validated questionnaire by face-to-face interview technique with which was conducted by trained interviewers.

    RESULTS: Mean age of the participants was 65.33 (5.87) year old with majority were still married. Female (55.7%) reported more sexual problems as evidenced by the higher proportion of those with lacked interest in having sex (72.5%), find sex is unpleasant (34.8%) and unable to come to orgasm (55.1%). Gender was found to have significant impact on every model obtained in the analysis for both sexual problems and perceptions. Female elderly were 10.6 times more likely to have sexual problem compared to male elderly (OR = 10.64, P

    Deterioration in muscle mass and muscle strength is common among the frail older persons, cause functional dependence and decrease in the quality of life. Therefore, the identification of cost-effective interventions to prevent or ameliorate frailty is crucially needed. The aim of this study is to determine the effectiveness of a Community-based Muscle Strengthening Exercise (COME) program to increase muscle strength among pre-frail older persons. This study was a quasi-experimental study. A total of 32 older persons aged 60 years and older with pre-frail symptoms were recruited from the community center. The COME was developed based on the Growing Stronger program and the Otago Home Exercise Program. COME was designed to strengthen all of the major muscle groups in the upper and lower extremities. The exercise program was conducted for 12 weeks and divided into 3 parts; (1) to strengthen the body slowly and gently, using only body weight, (2) to introduce dumbbells and ankle weights to increase strength and (3) to add various new ways to boost strength even more. Functional tests were measured before and after the intervention. The results revealed non-significant p-value for pre- and post-intervention comparison for all study outcomes. Observing the values of mean difference, the study intervention was shown to have slightly improved the time up and go (Mean difference = -0.25), and sit-to-stand duration (Mean difference = -0.41) as well as the handgrip strength (Mean difference = 0.68) among the participants. On the assessment of Cohen ES, all three improvements exhibited small effect sizes. Sit-to-stand duration was shown to have most benefited from the intervention with highest ES among the outcome variables (ES = 0.20). COME intervention program among pre-frail older persons showed favorable trend toward improvement of upper and lower extremities muscle strength. This study should be further tested in randomized control trial to confirm its effectiveness.

    AIM: To identify the determinants of sexual intimacy among married older people in Malaysia.

    METHODS: A cross-sectional study was carried out among 1294 married Malaysian older couples who were randomly selected from all 14 states in Malaysia. The data were collected by trained enumerators using a set of validated questionnaires consisting of eight sections, namely sociodemographic characteristics, chronic diseases, perceived health status, life satisfaction, body mass index, disability status (World Health Organization Disability Assessment Schedule), social support (Lubben Social Network Scale) and sexual intimacy.

    RESULTS: Having good social support (AOR 0.57, 95% CI 0.45-0.74) from family and friends were protective determinants against poor sexual intimacy in later life. Meanwhile, those who were aged 70-79 years (AOR 1.81, 95% CI 1.35-2.42), aged >80 years (AOR 35.49, 95% CI 4.80-262.18), women (AOR 1.47, 95% CI 1.13-1.90), non-Malay (AOR 1.93, 95% CI 1.50-2.48), received only informal education (AOR 1.81, 95% CI 1.35-2.42), had gastritis (AOR 2.62, 95% CI 1.58-4.34), had a stroke (AOR 3.83, 95% CI 1.04-14.12), perceived their current health status was satisfactory (AOR 1.52, 95% CI 1.15-2.00) and disabled based on the World Health Organization Disability Assessment Schedule (AOR 3.14, 95% CI 1.34-7.36) were at risk of poor sexual intimacy.

    CONCLUSIONS: The majority of older Malaysian couples were having poor sexual intimacy despite being still married and sleeping with their partners, reflecting the presence of underlying barriers towards sexual intimacy in later life among older Malaysians.

    BACKGROUND: Malaysia is experiencing population ageing and expects to be an aged nation by 2030. Depression is one of the common disorder among elderly worldwide and the prevalence of depression in Malaysia is expected to increase as a result of population ageing. The association of depression and sexual satisfaction was unclear, particularly among the elderly. Therefore, this study aimed to examine the association between depression and sexual satisfaction among the Malay elderly population.

    METHODS: One hundred and nine married community-dwelling elderly (Mean age = 63.23 years old) participated in this cross-sectional study. Hierarchical logistics regression was used to examine the association of depression on sexual satisfaction while controlling for potential confounders.

    RESULTS: Prevalence of depression and sexual dissatisfaction were 26.6% and 20.2%, respectively. Depression was significantly associated with sexual satisfaction (P = 0.002; OR = 0.19, 95% CI = 0.06, 0.66). Depressed participants were 81% less likely to experience sexual satisfaction compared to those without depression.

    LIMITATIONS: Cross-sectional study design assessing the association between depression and sexual satisfaction.

    CONCLUSIONS: Findings from this study suggest that attention should be given to the prevention and treatment of depression among the elderly as a mechanism to improve sexual health.

    INTRODUCTION: Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction. Magnetic resonance imaging (MRI) remains the imaging modality of choice, but its findings are not completely specific for clinically significant CSM. This cross-sectional study aims to determine the pathoanatomy of CSM in patients and analyze the correlations between clinical key symptoms, myelopathic signs, and MRI findings.

    METHODS: Patients with CSM aged 30 to 80 years old with no previous cervical spine disease or injuries were recruited. Clinical parameters include myelopathic hand signs and other clinical-specific tests. The MRI findings were analyzed for level of compression, underlying degenerative pathology, and parameters for cord compression.

    RESULTS: Thirty patients were recruited. The most common myelopathic signs observed were positive Hoffmann's sign and the presence of reverse brachioradialis reflex. All patients had either degenerative or prolapse disc changes on MRI. There was a positive correlation between the clinical key features with MRI parameters for canal and cord diameter. The transverse cord diameter, cord compression ratio, and approximate cord area were the only independent variables related to almost all the positive clinical specific tests. All three have a moderate to strong correlation with the clinical findings.

    CONCLUSION: The MRI parameters such as canal and cord size of the cervical spine are an objective reflection of compression on the spinal cord. Correlations observed indicate cord compression that plays a major role in the pathophysiology of CSM. These measurements are sensitive indicators of canal stenosis and play a significant role in predicting the severity and outcome of CSM.

    In response to the rising number of COVID-19-related deaths among older adults in Malaysia, observation concerning COVID-19-related mortality among older adults is of urgent public health importance. This study presents a review of the COVID-19-related death cases among older adults in Malaysia. Clinical and social demographic data of death cases officially released by the Ministry of Health Malaysia were reviewed. As of 12 June 2020, 81 older adult death cases were identified and included in this study. The mean age of the death cases was 71.88 years old. Even though 79% of these cases were male, gender was not likely to be associated with mortality. A substantial difference between the prevalence of diabetes among death cases and the nationwide population indicated that diabetes was more likely to be associated with mortality. Most of the studied deaths were individuals with pre-existing medical conditions, predominantly diabetes and hypertension, and those aged 70 years old or above. The mean time from hospitalisation to death was 11.83 days. Extra focus should be given to older adults in the prevention and control of COVID-19.

    PURPOSE: Disturbances of sleep have frequently been reported in individuals with migraine. On top of this, an elderly patient with migraine also suffers from sleep disturbances due to changes in physiologic and mental health associated with aging. This study aimed to compare several sleep factors, namely sleep quality, chronotype, and obstructive sleep apnea (OSA) risk, between elderly people with and without migraine.

    METHODS: This was a multicenter cross-sectional study conducted in 10 neurologic clinics located in Tehran, Iran, over 2 years. The sample size was calculated as 189, including 63 migraine and 126 non-migraine patients.

    RESULTS: A significant difference was observed in the mean score of the global Pittsburgh Sleep Quality Index (PSQI) between migraine and non-migraine groups (p-value = 0.002), and in the individual components of the PSQI. However, there were no significant differences in the frequency of different types of chronotype (p-value = 0.125, T = 1.541) or OSA risk between the two groups (p-value = 0.568, T = -0.573). The binary logistic regression model showed that the relationship between global PSQI and migraine was significant (p = 0.002).

    CONCLUSION: Sleep quality is a problem for elderly migraine sufferers. Meanwhile, certain factors such as chronotype and OSA have no significant relationship with migraine among community-dwelling seniors. Further studies are required to enhance our understanding of this observation.

    INTRODUCTION: Despite the high prevalence of post-stroke delirium in Malaysia, there are no studies on good practices related to its management. This study aimed to analyse the knowledge, attitude, perception, and factors associated with current practices related to delirium in acute stroke patients among health personnel at Hospital Sultan Abdul Aziz Shah (HSAAS) (formerly known as Hospital Pengajar Universiti Putra Malaysia).

    METHODS: This cross-sectional study was conducted from 26 April 2021 to 9 May 2021 (17 weeks). All health personnel from various departments managing patients with acute stroke in our centre were invited to participate. An online questionnaire was disseminated to assess their knowledge, attitude, perception, and current practices concerning delirium. Multiple logistic regression was used to examine the association between the independent and dependent variables. The level of significance was set at P < 0.05.

    RESULTS: The response rate was 22.49% (47 of 209 participants). More than half (61.7%, n = 29) had good current practices towards delirium in acute stroke patients. A significant association was found between knowledge and current practices related to delirium (P = 0.024). However, there was no significant association between current practices and sociodemographic factors (age, ethnicity, gender and job position), attitude, perceptions, screening barriers, or health service organisation.

    CONCLUSION: Most respondents had good current practices and knowledge in managing post-stroke delirium. Therefore, upskilling health personnel for managing this illness is essential to ensure good post-stroke care and improve prognosis related to delirium.

    BACKGROUND: This is a phase II randomised, double-blind, sham-controlled trial to evaluate the effectiveness and tolerability of repetitive transcranial magnetic stimulation for preventive treatment of episodic migraine amongst migraine subjects.

    METHODS: Subjects age 18 to 60 years will undergo a baseline evaluation to establish the diagnosis of migraine based on the International Classification of Headache Disorder 3rd Edition (ICHD-3). Those who fulfil the ICHD-3 criteria for episodic migraine and compliant to the headache diary during a month run-in period will be enrolled. A total of 76 subjects will be randomised to receive either transcranial magnetic stimulation or sham stimulation for 5 sessions within 2 weeks duration. Follow-up sessions will be conducted monthly for three consecutive months. Prior to treatment, subjects will be required to fill up questionnaires and undergo few procedures such as electroencephalography, transcranial Doppler ultrasound and biochemical analysis for serum serotonin, serum calcitonin gene-related peptide and serum beta-endorphin. These procedures will be repeated at month 3 after receiving the last treatment. The primary outcome measure of this study is the difference in mean monthly migraine days at baseline and at months 1, 2 and 3 after treatment sessions.

    DISCUSSION: Following evidence from previous studies showing restoration of dorsolateral prefrontal cortex (DLPFC) activation to almost normal level, the rTMS intervention will target left DLPFC in this study. An intermediate duration of treatment sessions is selected for this study. It is set to five treatment sessions given within 2 weeks duration.

    Knowledge about the biogeographic affinities of the world's tropical forests helps to better understand regional differences in forest structure, diversity, composition, and dynamics. Such understanding will enable anticipation of region-specific responses to global environmental change. Modern phylogenies, in combination with broad coverage of species inventory data, now allow for global biogeographic analyses that take species evolutionary distance into account. Here we present a classification of the world's tropical forests based on their phylogenetic similarity. We identify five principal floristic regions and their floristic relationships: (i) Indo-Pacific, (ii) Subtropical, (iii) African, (iv) American, and (v) Dry forests. Our results do not support the traditional neo- versus paleotropical forest division but instead separate the combined American and African forests from their Indo-Pacific counterparts. We also find indications for the existence of a global dry forest region, with representatives in America, Africa, Madagascar, and India. Additionally, a northern-hemisphere Subtropical forest region was identified with representatives in Asia and America, providing support for a link between Asian and American northern-hemisphere forests.
