Correlates of the HIV-associated neurocognitive disorders among adults living with HIV in Dodoma region, central Tanzania: A cross-sectional study.

BACKGROUND: HIV-associated neurocognitive disorders (HAND) continue to manifest despite advancements and improved antiretroviral therapy coverage. Neurocognitive impairment is a significant predictor of poor prognosis related to poor antiretroviral therapy adherence and retention in HIV care. METHODS: This cross-sectional study examined 397 participants attending cared for and treatment at Dodoma Regional Referral Hospital (DRRH) and selected by systematic sampling. The combination of Montreal Cognitive Assessment (MoCA), International HIV Dementia Scale (IHDS), and The Lawton Instrumental Activity of Daily Living (IADL) were used to assess HIV-associated neurocognitive disorders. Factors associated with HAND were determined using univariate and multivariable logistic regression. RESULTS: Of 397 participants, 234(59.1%) met the criteria for HAND with 231(58.2%) comprising asymptomatic neurocognitive disorder (ANI) or mild neurocognitive disorders (MND), and 3 (0.76%) HIV- associated dementia (HAD). Participants with HAND had significantly poorer performance in each cognitive domain on both MoCA and IHDS. Under multivariable regression, age of 55 years or above with Adjusted Odds Ratio (AOR): 3.5 (95%CI: 1.1, 11.6), p = 0.041 and female gender (AOR): 2.7 (95%CI: 1, 6, 4.5), p<0.001 were significantly associated with HAND. Adherence to antiretroviral therapy AOR: 0.4(95%CI: 0.2, 1.0), p = 0.044, and attaining primary education AOR: 0.3(95%CI: 0.1, 0.8), p = 0.01 or secondary education AOR: 0.1(95%CI: 0.03, 0.2), p<0.001 compared to having no formal education showed good cognitive performance. CONCLUSION: HIV-associated neurocognitive disorders are common in HIV, especially ANI and MND, are common in HIV infected Tanzanians. Both socio-demographic and clinical variables influence neurocognitive functioning in this population. Screening for mild neurocognitive disorders may be indicated if effective treatment becomes available.

Neurocognitive decline as a major predictor of nonadherence to antiretroviral therapy among adults living with HIV in Dodoma region, central Tanzania.

Background: The survival of people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome largely depends on good adherence to antiretroviral medications. Neuropsychiatric conditions such as major depressive disorders (MDDs) and neurocognitive disorders, in particular, are common in the HIV population and attributed to suboptimal adherence to antiretroviral treatment and overall poor clinical outcomes. This study aimed to determine the association between neurocognitive disorders and nonadherence to antiretroviral therapy (ART) in the Dodoma region's adult population living with HIV. Methods: The study was conducted in Dodoma Regional Referral Hospital using a cross-sectional design to assess 397 participants through a systematic sampling approach. Montreal Cognitive Assessment was used to determine neurocognitive function, while the Simplified Medical Adherence Questionnaire was used to assess nonadherence to ART. Logistic regression analysis was computed to determine the association between cognitive decline and nonadherence to ART while controlling for sociodemographic and clinical confounders. Results: Out of the 397 recruited participants, 266 (67.00%) and 41 (10.33%) met the criteria for neurocognitive decline and nonadherence to ART. Participants with cognitive impairment had a significantly poorer adherence rate than those without, even after controlling for confounders adjusted odds ratio (aOR): 2.183 (95% confidence interval [CI]: 1.031, 4.630, p = 0.0413). MDD was the only additional factor that remained significantly associated with ART nonadherence (aOR: 4.332, 95% CI: 1.634, 11.485, p = 0.0032). Conclusion: Neurocognitive disorders are strong predictor of suboptimal adherence to ART; a comorbid neuropsychiatric condition such as MDD may further compromise the ART adherence rate leading to poor HIV care and poor clinical outcome. Further research with systematic and more robust studies in the field will provide a baseline to design and integrate appropriate care models to maximize ART adherence in HIV care. Integration of psychiatric services in HIV care can benefit the overall patient outcome.

The influence of major depressive disorders on neurocognitive function among adults living with HIV/AIDS in a regional referral hospital in Dodoma, Tanzania.

OBJECTIVE: To determine the influence of major depressive disorders (MDD) on the cognitive function of adults living with HIV and the prevalence of neurocognitive impairment and major depressive disorders. METHODS: The study was a cross-sectional design conducted in a referral hospital in Dodoma region central Tanzania, with a sample of 397 participants attained through systematic sampling. Neurocognitive impairment was assessed by Montreal Cognitive Assessment (MoCA), while MDD was assessed using Mini International Neuropsychiatric Interview (M.I.N.I). Two-sample independent t-tests were done to compute the significance of the mean change of MoCA score between those with or without MDD. Univariate and multivariate ordinal logistic regression models were computed to determine the association between MDD and neurocognitive impairment across all cognitive domains. RESULTS: Of 397 recruited participants, 266 (66.00%) met the criteria for neurocognitive disorder and 22 (5.51%) had major depressive disorder. Participants with MDD performed significantly poorer on cognitive testing than those without MDD (mean difference = 3.74, p-value = 0.0009). Under univariate ordinal regression, impairments in the particular domains of visuospatial-executive function, attention, language, abstraction and orientation were significantly associated with MDD and abstraction (AOR: 3.922, 95% CI: 1.546-9.947, p = 0.0004) remained significant under multivariable regression. CONCLUSION: Major depressive disorder may negatively influence neurocognitive performance in both severity and pattern of presentation. Routine screening for depressive symptoms in HIV care can be beneficial for the overall patient's outcome. Systematic and well-designed studies in the area are crucial for understanding the interaction of neuropsychiatric disorders in the HIV population.

Knowledge, attitude and practice towards malaria among symptomatic patients attending Tumbi Referral Hospital: A cross-sectional study.

BACKGROUND: Despite significant improvement in prevention and control over the past decades malaria remains a significant public health concern in Tanzania with 93% of the population being at risk. To prevent malaria infection and promote malaria free zones, understanding the community's knowledge, attitudes, and practices toward malaria control are essential. This study therefore aimed at determining the levels of understanding, and attitudes, as well as socio-cultural aspects of malaria prevention and treatment-seeking behaviours among suspected malaria patients. METHODS: This study was a hospital based cross-sectional study, in which patients attending Tumbi Referral Hospital with symptoms and signs that warrant inclusion of suspicion of malaria, were recruited. We used a pre-tested semi-structured questionnaire to collect participants' demographic characteristics, as well as information on their knowledge, attitudes, and practices towards malaria infection. Data were analysed using Stata Version 12.1. RESULTS: We enrolled a total of 295 respondents of which 179 (60.68%) were females. Participants' ages ranged from 1-91 years, with a mean of 31.4 years. Seventy-nine (26.8%) patients reported having malaria in the previous 28 days, with 57 (72.2%) being laboratory confirmed. Only 52 (65.8%) individuals reported taking prescribed medications for malaria. A total of 277 (93.90%) were aware of malaria, and 264 (95.31%) knew that it is transmitted by mosquito. Nearly all participants (263, 94.95%), identified sleeping under bed nets to be protective against malaria. About half of the respondents either agreed 63 (22.74%) or strongly agreed 62 (22.38%) that malaria can be transmitted like the common cold. Self-reported mosquito net use was 88.09% (244). CONCLUSION: Despite the endemicity of malaria in our study site, patients had adequate knowledge, encouraging attitudes, and good practices related to malaria prevention and control.

Complex visual hallucinatory experience in an elderly blind woman with glaucoma: revisiting Charles Bonnet syndrome.

For fear of being ridiculed, individuals with visual hallucinations hide their experiences and thus remain unrecognized and miss treatment. An elderly blind woman secondary to glaucoma experienced visual hallucinations accompanied by gross behavior disturbances. She improved with sodium valproate after haloperidol failed and remained relatively improved upon 3 months follow-up.

Prevalence and Correlates of Intestinal Parasites among Patients Admitted to Mirembe National Mental Health Hospital, Dodoma, Tanzania.

BACKGROUND: Neglected tropical diseases continue to be one of the leading causes of morbidity and mortality in the developing world. Psychiatric patients are among groups at risk for parasitic infection although control and monitoring programs largely overlook this population. This study aimed at determining prevalence and factors associated with intestinal parasitic infection among patients admitted to a psychiatric facility. METHOD: The study followed cross-sectional design; all the residing patients that met the inclusion criteria were included in the survey. Stool samples were collected and examined by direct wet preparation and formol-ether concentration. Data were analyzed with STATA version 12.1; Chi-square test was computed to determine the level of significance at p value < 0.05. RESULTS: Of all 233 patients who returned the stool samples, 29 (12.45%) screened were positive for an intestinal parasite. There was no significant association between parasite carriage and age, sex, or duration of hospital stay. CONCLUSION: The study shows that intestinal parasitic infection is common among patients in a psychiatric facility and highlights that parasitic infections that enter through skin penetration may be a more common mode of transmission than the oral route. Furthermore, the study underscores the need for surveillance and intervention programs to control and manage these infections.

Abdominal epilepsy, an uncommon cause of chronic and recurrent abdominal pain: a case report.

Abdominal epilepsy is an uncommon cause of paroxysmal abdominal pain. It is relatively common in children, but very rare in adults. We report a case of 38-year-old, who reported with recurrent abdominal pain for 2 years. Electroencephalography confirmed the diagnosis; he responded well to carbamazepine and remains symptom-free on follow-up.
