Impact of exercise training on symptoms of depression, physical activity level and social participation in people living with HIV/AIDS: a systematic review and meta-analysis.

BMC Infect Dis 2022 May 16;22(1):469. Epub 2022 May 16.

Fakultat III, Hochschule Hannover - University of Applied Sciences and Arts, Expo Plaza, Hannover, 30539, Lower Saxony, Germany.

Background: Symptoms of depression are prevalent in people living with human immune deficiency virus/acquired immune deficiency syndrome (PLWHA), and worsened by lack of physical activity/exercises, leading to restriction in social participation/functioning. This raises the question: what is the extent to which physical exercise training affected, symptoms of depression, physical activity level (PAL) and social participation in PLWHA compared to other forms of intervention, usual care, or no treatment controls?

Method: Eight databases were searched up to July 2020, according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol. Only randomised controlled trials involving adults who were either on HAART/HAART-naïve and reported in the English language, were included. Two independent reviewers determined the eligibility of the studies, extracted data, assessed their quality, and risk of bias using the Physiotherapy Evidence Database (PEDro) tool. Standardised mean difference (SMD) was used as summary statistics for the mean primary outcome (symptoms of depression) and secondary outcomes (PAL and social participation) since different measuring tools/units were used across the included studies. Summary estimates of effects were determined using a random-effects model (I).

Results: Thirteen studies met the inclusion criteria with 779 participants (n = 596 participants at study completion) randomised into the study groups, comprising 378 males, 310 females and 91 participants with undisclosed gender, and with an age range of 18-86 years. Across the studies, aerobic or aerobic plus resistance exercises were performed 2-3 times/week, at 40-60 min/session, and for between 6-24 weeks, and the risk of bias vary from high to low. Comparing the intervention to control groups showed significant difference in the symptoms of depression (SMD = - 0.74, 95% confidence interval (CI) - 1.01, - 0.48, p ≤ 0.0002; I = 47%; 5 studies; 205 participants) unlike PAL (SMD = 0.98, 95% CI - 0.25, 2.17, p = 0.11; I = 82%; 2 studies; 62 participants) and social participation (SMD = 0.04, 95% CI - 0.65, 0.73, p = 0.91; I = 90%; 6 studies; 373 participants).

Conclusion: Physical exercise training could have an antidepressant-like effect in PLWHA but did not affect PAL and social participation. However, the high heterogeneity in the included studies, implies that adequately powered randomised controlled trials with clinical/methodological similarity are required in future studies.

Social Support, General Self-Efficacy, Fear of Falling, and Physical Activity Among Older Adults in a Middle-Income Country.

Gerontol Geriatr Med 2022 Jan-Dec;8:23337214221097750. Epub 2022 Apr 23.

Department of Physiotherapy, University of Benin Teaching Hospital, Benin City, Nigeria.

To investigate the levels and interrelationships between fear of falling (FOF), physical activity (PA), social support (SS), and general self-efficacy (GSE) among older adults in a Nigerian community. This was a cross-sectional survey involving 100 older adults (65.0% females; mean age = 74.25 ± 8.01 years) consecutively recruited from Nnewi community. Participants' FOF, PA, GSE, and SS were assessed using standardized questionnaires. Data were analyzed using descriptive statistics, Spearman rank order correlation, and structural equation modeling at a 0.05 level of significance. The participants' mean FOF, PA, GSE, and SS scores were 15.22 ± 7.43 (fearful), 114.76 ± 90.18 (low), 21.64 ± 8.25 (low) and 5.72 ± 1.19 (high) respectively. There were significant correlations between each pair of FOF, PA, GSE, and SS scores of the participants ( < .05). FOF and GSE were significant predictors of PA while GSE and SS were significant predictors of FOF. FOF and SS were high while PA and GSE were low in this sample of Nigerian older adults. Significant correlations existed between FOF, SS, GSE, and PA, with FOF and GSE being predictors of PA while GSE and SS significantly predicted FOF. Measures should be geared towards reducing FOF and improving PA, GSE, and SS in this group.

Cross-cultural adaptation and validation of the reintegration to normal living index into IGBO language among individuals with mobility disability.

J Patient Rep Outcomes 2019 Jul 12;3(1):40. Epub 2019 Jul 12.

Department of Medical Rehabilitation, College of Health Sciences, Nnamdi Azikiwe University, Nnewi Campus, Anambra State, 435101, Nigeria.

Background: Community reintegration is one of the most important elements of disability rehabilitation globally. Hence, there is need for availability of psychometrically-sound and culturally-specific instruments for its measurement. Most of the available community reintegration measures were developed and validated in developed countries and might therefore not be suitable for use in developing countries. This study was aimed at cross-culturally adapting and validating the original English visual analogue scale version of the Reintegration to Normal Living Index (RNLI) into Igbo Language and culture among people with mobility disability in Igbo land, Southeast Nigeria. The English version of the RNLI was cross-culturally adapted to Igbo following the American Association of Orthopaedic Surgeons' guideline. The RNLI was translated into Igbo Language, synthesized, back translated, and subsequently subjected to expert panel review, pretesting and cognitive debriefing interview. The final Igbo version of the RNLI was tested for internal consistency and construct validity in a sample of 102 consenting participants (61.8% males; 46.92 ± 20.91 years) recruited from conveniently sampled clinics and rehabilitation centres in Anambra and Enugu States of South-Eastern Nigeria. The construct (concurrent) validity was evaluated using Spearman rank correlation, scatter plot and Mann-Whitney U test while the internal consistency was evaluated using Cronbach's alpha at alpha level of 0.05.

Results: The RNLI was successfully cross-culturally adapted to Igbo with all the 11 items still retained. The mean total score of the participants on the RNLI was 58.62 ± 21.25. The internal consistency coefficient (α = 0.84) of Igbo version of the RNLI was excellent. The Spearman correlation coefficients between the participants' total, subscale and domain scores on the Igbo and the English versions of the RNLI (r = 0.81-0.95) were excellent. There was no significant difference between corresponding scores in the English and Igbo versions of the RNLI.

Conclusion: The Igbo version of the RNLI is a valid and reliable outcome measure among Igbo people living with mobility disabilities in Southeast Nigeria. It is therefore recommended for use among this group.

Effects of transcutaneous electrical nerve stimulation in the Management of Post-Injection Sciatic Pain in a non-randomized controlled clinical trial in Nnewi, Nigeria.

BMC Complement Altern Med 2018 Nov 26;18(1):310. Epub 2018 Nov 26.

Department of Medical Rehabilitation, Faculty of Health Sciences and Technology, University of Nigeria|, Enugu Campus, Enugu State, Nigeria.

Background: Many studies on transcutaneous electrical nerve stimulation (TENS) had been undertaken to explore its pain relieving efficiency on several medicals/surgical conditions but none, specifically, had been carried out to determine the effect it has on post-injection sciatic pain (PISP) which comes about from wrong administration of intramuscular pain. This study aims to assess the effects of TENS in the management of PISP.

Methods: A total of 72 PISP subjects comprising 40 test subjects and 32 control subjects participated in a non-randomized controlled clinical trial in the current study. Participants were recruited from Department of Physiotherapy, Nnamdi Azikiwe University Teaching Hospital, Nnewi and Landmark Physiotherapy Services, Nnewi. The participants were however blinded to the intervention method they will receive before being allotted conveniently to test/experimental group (TG) or control group (CG). A written informed consent was obtained from participants before enrollments in the study. TENS and sham TENS (STENS) was applied to 40 test and 32 subjects respectively, 3 times a week, and 1 hour per session for the 10 weeks the study lasted. The Visual Analogue Scale was used to collect baseline data as well as those of 2nd, 4th, 6th, 8th and 10th weeks after TENS and STENS interventions. The data analysis was performed with the Descriptive statistic of Mean ± SD, mean comparison test, repeated analysis of variance and paired wise t-test. Statistical level of significance was set at P < 0.05.

Result: Results of repeated measure ANOVA showed that the pain level among participants in the treatment group at the end (after 10 weeks) of the intervention was significantly lower than that of their counterparts in the control group (F = 16.26; p = 0.01); with the intervention accounting for the 19% of the variance. The effect size (partial eta squared) = 0.19.

Conclusion: The outcome of this research has proved the effectiveness of TENS in the management of PISP and is being recommended in the management of PISP.

Trial Registration: Pan Africa Clinical Trial Registry ( PACTR201805003408271 ). The study was registered retrospectively on the 29th May, 2018.

Effects of a 12-month task-specific balance training on the balance status of stroke survivors with and without cognitive impairments in Selected Hospitals in Nnewi, Anambra State, Nigeria.

Top Stroke Rehabil 2018 07 2;25(5):333-340. Epub 2018 May 2.

c Department of Medical Rehabilitation, Faculty of Health Sciences and Technology , Nnamdi Azikiwe University , Awka , Nigeria.

Background: Stroke results in varying levels of physical disabilities that may adversely impact balance with increased tendency to falls. This may intensify with cognitive impairments (CI), and impede functional recovery. Therefore, task-specific balance training (TSBT), which presents versatile task-specific training options that matches varied individual needs, was explored as a beneficial rehabilitation regime for stroke survivors with and without CI. It was hypothesized that there will be no significant difference in the balance control measures in stroke survivors with and without CI after a 12-month TSBT.

Objective: To determine if TSBT will have comparable beneficial effects on the balance control status of sub-acute ischemic stroke survivors with CI and without CI.

Methods: One hundred of 143 available sub-acute first ever ischemic stroke survivors were recruited using convenience sampling technique in a quasi-experimental study. They were later assigned into the cognitive impaired group (CIG) and non-cognitive impaired group (NCIG), respectively, based on the baseline presence or absence of CI, after screening with the mini-mental examination (MMSE) tool. With the help of four trained research assistants, TSBT was applied to each group, thrice times a week, 60 mins per session, for 12 months. Their balance was measured as Bergs Balance scores (BBS) at baseline, 4th, 8th, and 12th month intervals. Data were analyzed statistically using Kruskal Wallis test, and repeated measure ANOVA, at p < 0.05.

Results: There was significant improvement across time points in the balance control of CIG with large effect size of 0.69 after 12 months of TSBT. There was also significant improvement across time points in the balance control of NCIG with large effect size of 0.544 after 12 months of TSBT. There was no significant difference between the improvement in CIG and NCIG after 8th and 12th months of TSBT.

Conclusions: Within the groups, a 12-month TSBT intervention significantly improved balance control, respectively, but with broader effects in the CIG than NCIG. Importantly, though between-group comparison at baseline revealed significantly impaired balance control in the CIG than NCIG, these differences were not significant at the 8th month and non-existent at the 12th month of TSBT intervention. These results underscore the robustness of TSBT to evenly address specific balance deficits of stroke survivors with and without CI within a long-term rehabilitation plan as was hypothesized.

HIV-related knowledge, attitude and practices of healthy adults in Cross River State Nigeria: a population based-survey.

Pan Afr Med J 2017 4;27:170. Epub 2017 Jul 4.

Department of Chemical pathology, University of Calabar Teaching Hospital, Calabar, Nigeria.

Introduction: Human Immunodeficiency Virus (HIV) remains a global health problem disproportionately distributed across Nigeria. Cross river state (CRS), a tourist state, located in the Niger delta, has one of the highest prevalence rates. There is evidence that poor knowledge and stigmatization are obstacles to achieving universal access to HIV prevention programs. The objective of this study was to determine the Knowledge, Attitude and Practice (KAP) of HIV among adults resident in CRS, Nigeria.

Methods: A cross sectional descriptive survey design was employed. A total of 1,620 healthy adults were recruited. KAP towards HIV was assessed using a structured pre-tested questionnaire. Categorical variables were described as frequencies and continuous variables as median and interquartile range. Kruskal-Wallis test was used to determine relationship between variables and median KAP scores. P value < 0.05 was considered significant. All analyses were performed using Stata 12 statistical package.

Results: A total of 1,465 respondents completed the questionnaire correctly giving a response rate of 91%. The M: F ratio was 1:1.8. The median age was 38 years. Majority was married and had formal education. Knowledge of HIV and common routes of transmission was high (>80%). However, misconception that HIV can be transmitted through hugging, hand shake, mosquito bites and witch craft was also common (> 60%). The overall attitude and practice towards persons living with HIV infection was poor.

Conclusion: This study showed misconceptions in the knowledge and consequences of HIV infection which is associated with negative attitude towards persons living with HIV.

Characteristics, management, and outcomes of patients with hepatocellular carcinoma in Africa: a multicountry observational study from the Africa Liver Cancer Consortium.

Lancet Gastroenterol Hepatol 2017 02 3;2(2):103-111. Epub 2016 Dec 3.

Department of Internal Medicine, School of Medical Sciences, Cape Coast, Ghana.

Background: Hepatocellular carcinoma is a leading cause of cancer-related death in Africa, but there is still no comprehensive description of the current status of its epidemiology in Africa. We therefore initiated an African hepatocellular carcinoma consortium aiming to describe the clinical presentation, management, and outcomes of patients with hepatocellular carcinoma in Africa.

Methods: We did a multicentre, multicountry, retrospective observational cohort study, inviting investigators from the African Network for Gastrointestinal and Liver Diseases to participate in the consortium to develop hepatocellular carcinoma research databases and biospecimen repositories. Participating institutions were from Cameroon, Egypt, Ethiopia, Ghana, Ivory Coast, Nigeria, Sudan, Tanzania, and Uganda. Clinical information-demographic characteristics, cause of disease, liver-related blood tests, tumour characteristics, treatments, last follow-up date, and survival status-for patients diagnosed with hepatocellular carcinoma between Aug 1, 2006, and April 1, 2016, were extracted from medical records by participating investigators. Because patients from Egypt showed differences in characteristics compared with patients from the other countries, we divided patients into two groups for analysis; Egypt versus other African countries. We undertook a multifactorial analysis using the Cox proportional hazards model to identify factors affecting survival (assessed from the time of diagnosis to last known follow-up or death).

Findings: We obtained information for 2566 patients at 21 tertiary referral centres (two in Egypt, nine in Nigeria, four in Ghana, and one each in the Ivory Coast, Cameroon, Sudan, Ethiopia, Tanzania, and Uganda). 1251 patients were from Egypt and 1315 were from the other African countries (491 from Ghana, 363 from Nigeria, 277 from Ivory Coast, 59 from Cameroon, 51 from Sudan, 33 from Ethiopia, 21 from Tanzania, and 20 from Uganda). The median age at which hepatocellular carcinoma was diagnosed significantly later in Egypt than the other African countries (58 years [IQR 53-63] vs 46 years [36-58]; p<0·0001). Hepatitis C virus was the leading cause of hepatocellular carcinoma in Egypt (1054 [84%] of 1251 patients), and hepatitis B virus was the leading cause in the other African countries (597 [55%] of 1082 patients). Substantially fewer patients received treatment specifically for hepatocellular carcinoma in the other African countries than in Egypt (43 [3%] of 1315 vs 956 [76%] of 1251; p<0·0001). Among patients with survival information (605 [48%] of 1251 in Egypt and 583 [44%] of 1315 in other African countries), median survival was shorter in the other African countries than in Egypt (2·5 months [95% CI 2·0-3·1] vs 10·9 months [9·6-12·0]; p<0·0001). Factors independently associated with poor survival were: being from an African countries other than Egypt (hazard ratio [HR] 1·59 [95% CI 1·13-2·20]; p=0·01), hepatic encephalopathy (2·81 [1·72-4·42]; p=0·0004), diameter of the largest tumour (1·07 per cm increase [1·04-1·11]; p<0·0001), log α-fetoprotein (1·10 per unit increase [1·02-1·20]; p=0·0188), Eastern Cooperative Oncology Group performance status 3-4 (2·92 [2·13-3·93]; p<0·0001) and no treatment (1·79 [1·44-2·22]; p<0·0001).

Interpretation: Characteristics of hepatocellular carcinoma differ between Egypt and other African countries. The proportion of patients receiving specific treatment in other African countries was low and their outcomes were extremely poor. Urgent efforts are needed to develop health policy strategies to decrease the burden of hepatocellular carcinoma in Africa.

Challenges in the management of chronic HBV infection in West Africa: The clinician's perspective.

Trop Doct 2016 Jan 11;46(1):16-20. Epub 2014 Dec 11.

Chief Consultant Gastroenterologist/Reader, Department of Internal Medicine, Lagos State University Teaching Hospital, Lagos, Nigeria.

Background: Hepatitis B infection has become a public health issue in recent years. Approximately 350 million of the world's population are chronically infected reaching endemic proportions in West Africa. Guidelines for treatment are continuously improving but are becoming more complex.

Aim: To determine the challenges hepatologists experience in the management of patients with chronic hepatitis B.

Methods: This was a cross-sectional descriptive study conducted among hepatologists in West Africa during a regional hepatitis conference in 2013.

Results: Forty-six hepatologists completed the questionnaire. When evaluating a patient for chronic hepatitis B, the preferred investigations were: LFT (100%); abdominal ultrasound (93.5%); HBeAg (93.5%); HBV DNA (78%); HBsAg measure (22%); HBV genotype (15.2%); and liver biopsy (34.8%). Most had their patients on nucleoside/nucleotide analogue but follow-up visits after 1 year were problematic.

Conclusion: The majority of hepatologists had good intentions regarding the evaluation of their patients, but only a small percentage of patients are properly investigated.

Hematological parameters in association with outcomes in sickle cell anemia patients.

Indian J Med Sci 2011 Sep;65(9):393-8

Department of Hematology, Nnamdi Azikiwe University Teaching Hospital, Nnewi, Anambra State, Nigeria.

Introduction: Sickle cell disease (SCD) has a wide range of clinical presentation. We evaluated hematological parameters, which are widely evaluable and assessable, as indices of clinical outcome in SCD. These parameters, although largely established as indices of clinical outcome in other SCD populations, have not been widely evaluated in African patients.

Materials And Methods: One hundred and thirty six consecutive stable SCD patients who presented in the sickle cell clinic of a teaching hospital were studied retrospectively using a questionnaire. Hematological parameters of full blood count (FBC) for each patient were obtained using a cell counter. FBC parameters such as White blood cell count (WBC) were then statistically correlated with complications such as ankle ulcers, osteomylitis and others. A Chi-square text was used to compare frequencies and generate P values.

Results: The presence of sickle cell complications was significantly associated with raised white blood cell count (WBC) above 11 × 10(9)/l (P = 0.03).The WBC of the patients increased with increasing numbers of complications (P = 0.07). Mean packed cell volume (PCV) and WBC tended toward the reference range for age and sex (in apparently normal individuals) as the age at diagnosis of SCD increased. This trend was significant for PCV (P = 0.01).

Conclusion: Our data provide additional support that widely evaluable and assessable hematological parameters such as PCV and WBC can be used as indices to predict SCD outcome in African patients. This is likely to impart positively on individualized therapy.
