ABSTRACT

BACKGROUND: Pre-frailty is associated with increased healthcare utilization. Over the past decade, public health interventions such as community-based exercises to target pre-frailty have been increasingly studied. However, the effects of community-based exercises on clinical outcome measures amongst community-dwelling older adults with pre-frailty remain unclear. This review aims to better understand the effects of community-based exercise on physical function, cognition, quality of life and frailty status in community-dwelling pre-frail older adults. A secondary objective was to investigate the optimal exercise parameters on clinical outcomes. METHODS: Searches of MEDLINE, CINAHL, Google Scholar and Web of Science databases were conducted. Articles were included if they were randomized controlled trials (RCTs), and excluded if the participants consist of less than 50% pre-frail community-dwelling older adults. Meta-analyses (where possible) with either a fixed- or random- effect(s) model, standardized mean difference (SMD), odds ratio (OR) and tests of heterogeneity were performed. Multivariable meta-regression was performed to identify predictors of statistically significant outcome measures. The risk of bias was assessed using the modified Cochrane Risk-of-Bias tool. RESULTS: Twenty-two RCTs with 900 participants in the experimental group and 1015 participants in the control group were included. When compared to minimal intervention, community-based exercises significantly improved lower limb strength (10 RCTs, 384 participants in the experimental group and 482 participants in the control group) with SMD 0.67 (95% CI 0.29 to 1.04), and lower limb function (5 RCTs, 120 participants in the experimental group and 219 participants in the control group) with SMD 0.27 (95% CI 0.03 to 0.51). Those who have received community-based exercises were more likely to reverse from pre-frailty to healthy state (OR = 2.74, 95% CI 1.36 to 5.51) (6 RCTs, 263 participants in the experimental group and 281 participants in the control group). The frequency of exercise sessions was a significant predictor of the effect size for gait speed (P<0.05). CONCLUSIONS: Community-based exercise intervention is superior to minimal intervention for improving health status in pre-frail older adults. This has implications on the implementation of community-based exercise intervention by healthcare providers and policymakers. OTHER: Nil funding for this review.

ABSTRACT

BACKGROUND: The identification of cancer driver genes from sequencing data has been crucial in deepening our understanding of tumor biology and expanding targeted therapy options. However, apart from the most commonly altered genes, the mechanisms underlying the contribution of other mutations to cancer acquisition remain understudied. Leveraging on our whole-exome sequencing of the largest Asian lung adenocarcinoma (LUAD) cohort (n = 302), we now functionally assess the mechanistic role of a novel driver, PARP4. METHODS: In vitro and in vivo tumorigenicity assays were used to study the functional effects of PARP4 loss and mutation in multiple lung cancer cell lines. Interactomics analysis by quantitative mass spectrometry was conducted to identify PARP4's interaction partners. Transcriptomic data from cell lines and patient tumors were used to investigate splicing alterations. RESULTS: PARP4 depletion or mutation (I1039T) promotes the tumorigenicity of KRAS- or EGFR-driven lung cancer cells. Disruption of the vault complex, with which PARP4 is commonly associated, did not alter tumorigenicity, indicating that PARP4's tumor suppressive activity is mediated independently. The splicing regulator hnRNPM is a potentially novel PARP4 interaction partner, the loss of which likewise promotes tumor formation. hnRNPM loss results in splicing perturbations, with a propensity for dysregulated intronic splicing that was similarly observed in PARP4 knockdown cells and in LUAD cohort patients with PARP4 copy number loss. CONCLUSIONS: PARP4 is a novel modulator of lung adenocarcinoma, where its tumor suppressive activity is mediated not through the vault complex-unlike conventionally thought, but in association with its novel interaction partner hnRNPM, thus suggesting a role for splicing dysregulation in LUAD tumorigenesis.

ABSTRACT

BACKGROUND: Previous literature suggests that transversus abdominis (TrA) activation is diminished in chronic low back pain (cLBP) subjects compared to healthy subjects in less-functional positions. However, few studies have investigated the effects of upright functional movement on TrA activation in cLBP individuals. OBJECTIVE: This pilot study aimed to compare TrA activation characteristics in healthy and cLBP subjects during the movement of double leg standing (DLS) to single leg standing (SLS) and to a 30∘ single leg quarter squat (QSLS). METHODS: TrA activation was determined by the percentage change in TrA thickness from DLS to SLS and DLS to QSLS. TrA thickness was measured in 14 healthy and 14 cLBP participants using ultrasound imaging with a probe holder at 20 mm and 30 mm from the fascia conjunction point. RESULTS: At both measurement points (20 and 30 mm), there were no significant main effects of body sides, lower limb movements and the interactions between them on TrA activations between the healthy and cLBP participants even after covariates were adjusted for (all p> 0.05). CONCLUSIONS: Results from this study suggest the evaluation of TrA activation during upright functional movements as part of an assessment for cLBP management may not be suggested.

ABSTRACT

Mis-sense mutations affecting TP53 promote carcinogenesis both by inactivating tumor suppression, and by conferring pro-carcinogenic activities. We report here that p53 DNA-binding domain (DBD) and transactivation domain (TAD) mis-sense mutants unexpectedly activate pro-carcinogenic epidermal growth factor receptor (EGFR) signaling via distinct, previously unrecognized molecular mechanisms. DBD- and TAD-specific TP53 mutants exhibited different cellular localization and induced distinct gene expression profiles. In multiple tissues, EGFR is stabilized by TAD and DBD mutants in the cytosolic and nuclear compartments respectively. TAD mutants promote EGFR-mediated signaling by enhancing EGFR interaction with AKT via DDX31 in the cytosol. Conversely, DBD mutants maintain EGFR activity in the nucleus, by blocking EGFR interaction with the phosphatase SHP1, triggering c-Myc and Cyclin D1 upregulation. Our findings suggest that p53 mutants carrying gain-of-function, mis-sense mutations affecting two different domains form new protein complexes that promote carcinogenesis by enhancing EGFR signaling via distinctive mechanisms, exposing clinically relevant therapeutic vulnerabilities.

ABSTRACT

OBJECTIVE: Uptake for cervical cancer screening remains well below the 80% target as recommended by Brunei's National Cervical Cancer Prevention and Control plan. We conducted a pilot study to determine the reasons for non-attendance and explore their acceptance of human papillomavirus (HPV) self-sampling as an alternative to the Pap test. METHODS: A cross-sectional study was conducted at a primary healthcare center in Brunei, from January to December 2019. We recruited screening non-attendees, defined as women who were eligible for Pap test but who either never, or did not have one within the recommended screening interval of 3 years. This recruitment was done conveniently among women attending outpatient care and/or child health services at the primary healthcare center. Participants were first asked to complete a self-administered paper-based questionnaire on their reasons for screening non-attendance, and then invited for HPV self-sampling. Among those who agreed to participate in HPV self-sampling, they were asked to complete a second questionnaire on the self-sampling procedure and their samples were tested for high-risk HPV (hr-HPV). Results were analyzed using descriptive and inferential statistics. RESULT: We enrolled 174 screening non-attendees, out of which 97 (55.7%) also participated in HPV self-sampling. The main reasons for not attending Pap test screening were fear of bad results (16.1%, n = 28); embarrassment (14.9%, n = 26) and lack of time due to home commitments (10.3%, n = 18). When compared to those who agreed to participate in HPV self-sampling, those who declined were significantly older (p = 0.002) and less likely to agree that they are susceptible to cervical cancer (p = 0.023). They preferred to receive Pap test-related information from healthcare workers (59.0%, n = 155), social messaging platforms (28.7%, n = 51) and social media (26.4%, n = 47). HPV self-sampling kits were positively received among the 97 participants, where > 90% agreed on its ease and convenience. Nine (9.3%) tested positive for hr-HPV, out of which eight were non-16/18 HPV genotypes. CONCLUSION: Our findings suggest that promoting awareness on cervical cancer, clarifying any misconceptions of Pap test results, and highlighting that the disease is preventable and that early detection through screening can facilitate successful treatment would help increase screening uptake among Bruneian non-attendees. Response to HPV self-sampling was highly positive, suggesting the possibility of implementing this strategy in the local setting. Our high detection of non-16/18 HPV genotypes suggest high prevalence of other hr-HPV genotypes in Brunei. Larger studies should be conducted to further validate our findings.

ABSTRACT

Kimura's disease is a rare chronic inflammatory disorder of unknown etiology which typically presents with subcutaneous nodules in the head and neck region and is frequently associated with regional lymphadenopathy or salivary gland enlargement. Peripheral blood eosinophilia and elevated serum immunoglobulin E levels are constant features of the disease. We present herein a 31-year-old male patient who presented with chronic neck lymphadenopathy. Kimura's disease was diagnosed on fine needle aspiration cytology, the patient initially decided not to have further intervention. He presented 6 years later with lymphadenopathy and was treated with surgery. The diagnosis of Kimura's disease was confirmed on histopathology. This patient had the disease for 6 years and did not have the typical features of peripheral eosinophilia and raise serum IgE level.

ABSTRACT

Single cell genomics offers an unprecedented resolution to interrogate genetic heterogeneity in a patient's tumour at the intercellular level. However, the DNA yield per cell is insufficient for today's sequencing library preparation protocols. This necessitates DNA amplification which is a key source of experimental noise. We provide an evaluation of two protocols using micro-fluidics based amplification for whole exome sequencing, which is an experimental scenario commonly used in single cell genomics. The results highlight their respective biases and relative strengths in identification of single nucleotide variations. Towards this end, we introduce a workflow SoVaTSiC, which allows for quality evaluation and somatic variant identification of single cell data. As proof of concept, the framework was applied to study a lung adenocarcinoma tumour. The analysis provides insights into tumour phylogeny by identifying key mutational events in lung adenocarcinoma evolution. The consequence of this inference is supported by the histology of the tumour and demonstrates usefulness of the approach.

ABSTRACT

OBJECTIVE: The purpose of this study was to systematically review the effects of spinal manipulation on muscular strength in healthy individuals and conduct a meta-analysis to appraise the quality of evidence. METHODS: Articles were searched and retrieved from MEDLINE, EMBASE, CINAHL, Cochrane Library, PubMed, Academic Search Premier, SPORTDiscus, and AMED. Searches were conducted in September 2017 without a limit on the starting period. The Physiotherapy Evidence Database scale was used to appraise the quality of the included studies. Data from eligible articles were pooled, and meta-analyses were conducted. The quality of evidence was appraised by the Grading of Recommendations, Assessment, Development and Evaluations approach. The registration number for the review on PROSPERO is CRD42017075215. RESULTS: A total of 911 records were screened, and 3 randomized controlled trials were eligible to be included in this review. There was a significant pooled standardized mean difference in isometric strength (0.93, 95% confidence interval [CI], 0.17-1.68; P = .02) between the experimental and control groups, with a moderate level of heterogeneity. CONCLUSION: This review suggests that spinal manipulative therapy augments the percentage of change in isometric strength gain among healthy participants when compared to no intervention or sham manipulation. However, the heterogeneity of pooled studies in this review suggests that the results should be interpreted with caution.

ABSTRACT

INTRODUCTION: In recent years, there has been an increase in the use of motor imagery (MI) in the rehabilitation of musculoskeletal pain conditions. Across the literature, most reviews have yet to consider Laterality Judgement Task training as a form of MI method. This review aimed to evaluate the effectiveness of using MI as an adjunct to standard rehabilitation on the improvement of pain and range of motion parameters when managing patients with musculoskeletal pain conditions. METHODS: Searches of 8 major electronic databases were conducted. Data for pain and range of motion were extracted. Meta-analyses (where possible) with either a fixed or random-effect(s) model, standardized mean differences (SMDs), and tests of heterogeneity were performed. RESULTS: Eight clinical controlled trials were identified and included in the meta-analyses. When compared with standard rehabilitation alone, the adjunctive role of MI provided superior pain relief (pooled SMD, -2.25; 95% confidence interval, -4.11 to -0.4; P=0.02), and greater improvement in range of motion (pooled SMD, 3.04; 95% confidence interval, 0.66-5.43; P=0.01) in chronic musculoskeletal pain disorders. DISCUSSION: The results suggest that MI may be effective for pain relief and improvement in range of motion among chronic musculoskeletal pain conditions, although conclusion is based on a limited certainty of evidence as assessed using the GRADES (Grading of Recommendation, Assessment, Development and Evaluation) approach.

ABSTRACT

BACKGROUND: Early quadriceps muscle strength assessment after a total knee arthroplasty (TKA) provides timely information on progress, but little is known about the pain profile and predictive validity associated with common clinical muscle strength tests. This study aimed to, in patients with a recent TKA, examine the associations of isometric and isotonic quadriceps strength with gait speed, accounting for knee pain experienced during testing. METHODS: A sample of 76 patients (mean age 68 years; 46 women) with a recent TKA (median, 1.5 months) participated. Quadriceps strength was measured on both limbs using a knee extension machine. Isotonic strength was assessed with a one-repetition maximum test. Isometric strength was measured at 40° and 70° of knee flexion using a custom-built load cell. To allow for valid comparisons between the tests, quadriceps strength symmetry ratios were calculated. Knee pain during testing was measured using an 11-point pain scale. Fast gait speed was measured using the 10-m walk test. RESULTS: Compared with isotonic test, quadriceps strength ratio was higher for the 40° flexion isometric test (P = 0.01), and this difference may be explained by the lower knee pain intensity elicited during the isometric tests (P's < 0.001). All strength measures were closely associated with fast gait speed after adjustment for knee pain and covariates (P's < 0.001). CONCLUSIONS: Early in the post-TKA period, isometric and isotonic strength tests may be used to assess quadriceps strength but these tests are not interchangeable. Isometric quadriceps testing may be preferable to isotonic testing as it was associated with lower knee pain intensity.

ABSTRACT

OBJECTIVE: To synthesize the evidence regarding the diagnostic value of simple ancillary tests post cerebrospinal fluid drainage in normal pressure hydrocephalus. DATA SOURCES: MEDLINE, CINAHL, PsycINFO, Scopus, Web of Science, and Cochrane library databases; last searched on 12 September 2017. REVIEW METHODS: This review was performed applying the steps of the PRISMA statement. The QUADAS 2 tool was used to assess the risk of bias. Prospective and retrospective trials were systematically reviewed, and data on diagnostic accuracy were extracted. Meta-analysis (where possible) was performed. Hierarchical summary receiver operating characteristic package was used to calculate pooled estimates of included diagnostic studies. RESULTS: Seventeen trials (with 812 subjects in total) were identified for inclusion in the meta-analyses for the 18-meter walk test, video-recorded gait performance, cognitive test, and Timed Up and Go Test. The summary estimates of sensitivity and specificity for the 18-meter walk test was 0.83 (95% CI 0.57 to 0.99) and 0.67 (95% CI 0.33 to 0.95), video-recorded gait performance was 0.85 (95% CI 0.47 to 0.99) and 0.68 (95% CI 0.33 to 0.96), cognitive test was 0.82 (95% CI 0.41-0.99) and 0.75 (95% CI 0.39-0.99), and Timed Up and Go Test was 0.89 (95% CI 0.79-0.95) and 0.63 (95% CI 0.24-0.90), respectively. CONCLUSION: This review highlights the diagnostic value of the 18-meter walk test, video-recorded gait performance, cognitive test, and Timed Up and Go Test in predicting shunt outcomes among adults with normal pressure hydrocephalus.

ABSTRACT

BACKGROUND: Risk for falls in older adults has been associated with falls efficacy (self-perceived confidence in performing daily physical activities) and postural balance, but available evidence is limited and mixed. We examined the interaction between falls efficacy and postural balance and its association with future falls. We also investigated the association between falls efficacy and gait decline. METHODS: Falls efficacy, measured by the Modified Falls Efficacy Scale (MFES), and standing postural balance, measured using computerized posturography on a balance board, were obtained from 247 older adults with a falls-related emergency department visit. Six-month prospective fall rate and habitual gait speed at 6 months post baseline assessment were also measured. RESULTS: In multivariable proportional odds analyses adjusted for potential confounders, falls efficacy modified the association between postural balance and fall risk (interaction P = 0.014): increasing falls efficacy accentuated the increased fall risk related to poor postural balance. Low baseline falls efficacy was strongly predictive of worse gait speed (0.11 m/s [0.06 to 0.16] slower gait speed per IQR decrease in MFES; P < 0.001). CONCLUSION: Older adults with high falls efficacy but poor postural balance were at greater risk for falls than those with low falls efficacy; however, low baseline falls efficacy was strongly associated with worse gait function at follow-up. Further research into these subgroups of older adults is warranted. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01713543 .

ABSTRACT

OBJECTIVES: The impaired attenuation of pain by the application of a noxious conditioning stimulus at a segmentally distinct site, known as conditioned pain modulation (CPM), has been implicated in clinical pain states. Chronic lateral epicondylalgia (LE), which is characterized by lower pressure pain thresholds (PPTs) at sites remote to the affected elbow and spinal cord hyperexcitability, is a clinical pain state that might plausibly involve less efficacious CPM. This study aimed to determine whether LE exhibits a less efficacious CPM compared with that in pain-free controls. RESULTS: Results: Twenty participants with LE, aged 50.7 years (SD=7.05) and who had their condition for 10.2 months (range: 2 to 80 mo), were matched by age and sex to 22 pain-free participants. All participants indicated their PPT over the lateral epicondyle(s) before and during a conditioning noxious heat stimulus that was applied over the calf. A CPM score was calculated as the difference between the PPT before and during the heat pain-conditioning stimulus expressed as a percentage of PPT before the heat pain-conditioning stimulus. The condition (LE vs. control) by side (affected vs. unaffected) analysis of variance revealed a significant condition effect (P=0.001), but not side effect (P=0.192) or side-by-condition interaction effect (P=0.951). Follow-up tests for the effect of condition revealed a mean deficit in CPM of -24.5% (95% confidence interval, -38.0 to -11.0) in LE compared with that in pain-free participants. DISCUSSION: The results that suggest an impaired ability to modulate pain might be associated with the previously observed spinal cord hyperexcitability and the mechanical hyperalgesia that characterizes LE.

ABSTRACT

Recent efforts have attempted to convert non-blood cells into hematopoietic stem cells (HSCs) with the goal of generating blood lineages de novo. Here we show that hematopoietic transcription factors Scl, Lmo2, Runx1 and Bmi1 can convert a developmentally distant lineage (fibroblasts) into 'induced hematopoietic progenitors' (iHPs). Functionally, iHPs generate acetylcholinesterase+ megakaryocytes and phagocytic myeloid cells in vitro and can also engraft immunodeficient mice, generating myeloerythoid and B-lymphoid cells for up to 4 months in vivo. Molecularly, iHPs transcriptionally resemble native Kit+ hematopoietic progenitors. Mechanistically, reprogramming factor Lmo2 implements a hematopoietic programme in fibroblasts by rapidly binding to and upregulating the Hhex and Gfi1 genes within days. Moreover the reprogramming transcription factors also require extracellular BMP and MEK signalling to cooperatively effectuate reprogramming. Thus, the transcription factors that orchestrate embryonic hematopoiesis can artificially reconstitute this programme in developmentally distant fibroblasts, converting them into engraftable blood progenitors.

ABSTRACT

The need to evaluate the impact of interprofessional education (IPE) on learner outcomes is clear, but assessment of IPE's impact on patient health and well-being is lacking. This mixed-methods study evaluated perspectives of community volunteers, health mentors (HMs) who have at least one chronic condition, who participated in an IPE curriculum. In May 2014, 93 HMs concluding the Health Mentors Program completed a survey evaluating their student teams according to the Interprofessional Education Collaborative core competencies' four domains and program impact on health/wellbeing using a 4-point Likert scale (1=strongly disagree; 4=strongly agree). The average response to statements regarding the four domains of values/ethics, roles/responsibilities, communication, and teamwork statements were all >3.0. HMs rated program satisfaction on a 10-point scale (1=least satisfied, 10=most satisfied) and answered open-ended outcome questions. The average program satisfaction score was 9.13±1.43; increased motivation to make and maintain healthy behaviors was reported. In a follow-up focus group with 10 mentors, high satisfaction levels from working with interprofessional student teams were reported, and substantial improvements in managing health conditions and improving overall health status were relayed. Further studies will determine if the patient-reported outcomes of the mentors correlate with objective health measures.

ABSTRACT

PURPOSE: We analyzed student reflection essays to evaluate the impact of an interprofessional education (IPE) curriculum on what students value and personally learn from their participation. METHODS: After completing a 2-year IPE curriculum in the Health Mentors Program (HMP), while partnered with a mentor with chronic disease(s), 264 students from six health professions submitted personal reflection papers, using the Rolfe Reflection-in-Action model. A sample of 60 essays was analyzed using conventional content analysis guided by grounded theory. RESULTS: Qualitative analysis revealed 15 themes and 14 subthemes in the essays. The themes and subthemes were organized into four main categories: program, mentor, team, and self. Most students viewed the HMP curricular design positively. In particular, they cited the team-based home visit as a critical piece in changing their perceptions of the impact of chronic disease on their health mentor. Mentors' positive attitude and approach toward life also had a profound impact on students. Approximately half of the students identified positive team dynamics as a key component for optimal patient care and better health outcomes, noting improved understanding of team members' professional roles and responsibilities after working together in this longitudinal IPE program. The "self" category had the highest frequency count, with students describing positive changes in self-assessed knowledge, skills, and attitudes. CONCLUSIONS: Our findings suggest that reflective writing is an effective exercise through which students can explore their attitudes toward IPE and team-based care of individuals with chronic diseases. After participation in this IPE curriculum, students identified having an improved understanding of collaborative practice goals, indicative of meeting an IPE core competency, and described a new understanding of patient-centeredness.

ABSTRACT

The tumour-initiating cell (TIC) model accounts for phenotypic and functional heterogeneity among tumour cells. MicroRNAs (miRNAs) are regulatory molecules frequently aberrantly expressed in cancers, and may contribute towards tumour heterogeneity and TIC behaviour. More recent efforts have focused on miRNAs as diagnostic or therapeutic targets. Here, we identified the TIC-specific miRNAs, miR-1246 and miR-1290, as crucial drivers for tumour initiation and cancer progression in human non-small cell lung cancer. The loss of either miRNA impacted the tumour-initiating potential of TICs and their ability to metastasize. Longitudinal analyses of serum miR-1246 and miR-1290 levels across time correlate their circulating levels to the clinical response of lung cancer patients who were receiving ongoing anti-neoplastic therapies. Functionally, direct inhibition of either miRNA with locked nucleic acid administered systemically, can arrest the growth of established patient-derived xenograft tumours, thus indicating that these miRNAs are clinically useful as biomarkers for tracking disease progression and as therapeutic targets.

ABSTRACT

OBJECTIVES: The purpose was to synthesize the current evidence for the impact of muscle fatigue on measures for active repositioning task of the glenohumeral or scapulothoracic movements including the absolute error and/or scapulothoracic resting alignment. METHODS: We searched the PubMed, EMBASE, MEDLINE, CINAHL, SCOPUS, SportDiscuss and the Cochrane library databases. We included papers using a fatiguing task as part of their experimental design. Meta-analyses were undertaken for the active repositioning acuity of the glenohumeral outer/inner range of external rotation, glenohumeral inner range of internal rotation and scapulothoracic resting alignment in the scapular upward/downward rotation, anterior/posterior tilt and protraction/retraction planes. Qualitative data synthesis with standardized mean difference (SMD) was also conducted. RESULTS: There was a significantly pooled SMD, -2.10 (95% confidence interval -2.57 to -1.63), P < 0.001) in active repositioning acuity of the glenohumeral outer range of external rotation before and after a fatiguing task. However, the pooled SMD in active repositioning acuity for other glenohumeral movements and scapulothoracic resting positions were not significant (P > 0.05). CONCLUSION: Shoulder muscle fatigue impairs active repositioning acuity of the glenohumeral outer range of external rotation. Conversely, the current evidence does not support such impairment for the remaining glenohumeral movements and scapulothoracic resting alignments..

ABSTRACT

BACKGROUND: Worldwide, the incidence of cancers is increasing and is becoming a major public health issue, including those in the Asia Pacific region. South-East Asia is a region with diverse populations with different disease spectra. This study looked at the spectrum of cancers among South-East Asians working in Brunei Darussalam. MATERIALS AND METHODS: The cancer registry from 1994 to 2012 maintained by the State Laboratory was retrospectively reviewed. Crude incidence rates were calculated based on the population census of 2010. RESULTS: Altogether, there was a total of 418 cancer cases diagnosed among South-East Asians, giving an incidence of 5.1% (n=418/8,253). The affected nationals in decreasing frequency were Malaysians (53.1%), followed by Filipinos (25.8%), Indonesians (15.3%), Thais (3.8%), Myanmese (1.7%) and Vietnamese (0.2%) with no recorded cases for Singapore and the People's Republic of Laos. The overall mean age of diagnosis was 46.1±4.2 years old, with an increasing trend over the years (p<0.05 ANOVA). The overall gender ratio was 42.3:57.7 (male:female), more females among the Filipinos and Indonesians, more males among the Thais, and equal representation among the Malaysians and the Myanmese. The most common were cancers of the digestive system (19.9%), followed by female reproductive/gynecologic system (16.0%), breast (15.6%), hematological/lymphatic (12.0%) and head/neck (8.1%). There were differences in the prevalence of cancers among the various nationalities with highest crude incidence rate among the Myanmese (141.2/100,000), followed by the Malaysian (88.5/100,000), and the Filipinos (40.6/100,000) and the lowest among the Thais (18.4/100,000), Indonesians (10.5/100,000) and the Vietnamese (6.3/100,000). CONCLUSIONS: Cancers among South-East Asian residing in Brunei Darussalam accounted for 5.1% of all cancers. The most common cancers were cancers of the digestive, gynecologic/female reproductive system and breast with certain types slowly increasing in proportions. There mean age of diagnoses was increasing.

ABSTRACT

OBJECTIVES: In nerve-related chronic musculoskeletal (MS) disorders, neural tissue management is used to relieve pain by balancing the relative movement of neural tissues and their surrounding tissues. To date, there has not been any review evaluating the magnitude of this treatment effect in nerve-related chronic MS pain. The aim of this review was to compare pain and disability in individuals with nerve-related chronic MS pain who were treated with neural tissue management with those who received minimal or other treatment approaches. METHODS: Searches of 8 major electronic databases were conducted, and data on pain and disability scores were extracted. Meta-analyses (where possible) with either a fixed-effect(s) or random-effect(s) model, standardized mean differences (SMDs), and tests of heterogeneity were performed. RESULTS: Twenty clinically controlled trials were identified and included in the meta-analyses. When compared with minimal intervention, neural mobilization provided superior pain relief (pooled SMD=-0.77; 95% confidence interval [CI], -1.11 to -0.42; P<0.0001), and reduction in disability (pooled SMD=-1.06; 95% CI, -1.97 to -0.14; P=0.02), after post hoc sensitivity analyses. No significant differences were found when comparing neural mobilization with other treatment approaches for pain (pooled SMD=-0.67; 95% CI, -2.03 to 0.69; P=0.33), after post hoc sensitivity analysis, and disability (pooled SMD=-0.03; 95% CI, -0.54 to 0.59; P=0.93). DISCUSSION: Neural tissue management is superior to minimal intervention for pain relief and reduction of disability in nerve-related chronic MS pain. Existing evidence does not establish superiority of neural mobilization over other forms of intervention in reducing pain and disability in individuals with nerve-related chronic MS pain.
