Abstract
OBJECTIVE To study the epidemiology and outcomes of delirium among hospitalized patients in Zambia. METHODS We conducted a prospective cohort study at the University Teaching Hospital in Lusaka, Zambia, from October 2017 to April 2018. The primary exposure was delirium duration over the initial 3 days of hospitalization, assessed daily using the Brief Confusion Assessment Method. The primary outcome was 6-month mortality. Secondary outcomes included 6-month disability, evaluated using the World Health Organization Disability Assessment Schedule 2.0. FINDINGS 711 adults were included (median age, 39 years; 461 men; 459 medical, 252 surgical; 323 with HIV). Delirium prevalence was 48.5% (95% CI, 44.8%-52.3%). 6-month mortality was higher for delirious participants (44.6% [39.3%-50.1%]) versus non-delirious participants (20.0% [15.4%-25.2%]; P < .001). After adjusting for covariates, delirium duration independently predicted 6-month mortality and disability with a significant dose-response association between number of days with delirium and odds of worse clinical outcome. Compared to no delirium, presence of 1, 2 or 3 days of delirium resulted in odds ratios for 6-month mortality of 1.43 (95% CI, 0.73-2.80), 2.20 (1.07-4.51), and 3.92 (2.24-6.87), respectively (P < .001). Odds of 6-month disability were 1.20 (0.70-2.05), 1.73 (0.95-3.17), and 2.80 (1.78-4.43), respectively (P < .001). CONCLUSION Among hospitalized medical and surgical patients in Zambia, delirium prevalence was high and delirium duration independently predicted mortality and disability at 6 months. This work lays the foundation for prevention, detection, and management of delirium in low-income countries. Long-term follow up of outcomes of critical illness in resource-limited settings appears feasible using the WHO Disability Assessment Schedule.

Abstract
We evaluated national trends of in-hospital discharge rates, mortality outcomes, health care costs, length of stay in HIV patients with cognitive disorders. Neurological involvement in HIV is commonly associated with cognitive impairment termed as HIV-associated neurocognitive disorder (HAND) which includes a spectrum of neurocognitive dysfunction associated with HIV infection. Although severe and progressive neurocognitive impairment has become rare in HIV patients in the era of potent antiretroviral therapy, a majority of HIV patients have mild to moderate degree of neurocognitive impairment. Study population for this analysis was derived from the Nationwide Inpatient Sample from 2005 to 2014. Patients with ICD-9 code of HIV (042) with discharge diagnosis (Dx) listed top 1 through 5 were included in the analysis. Within this population, we identified patients with cognitive impairment using ICD-9 codes of 294 (persistent mental disorders; organic psychotic brain syndromes (chronic), 323.9 (encephalitis, myelitis, and encephalomyelitis), 331.83 (mild cognitive impairment) with Dx listed from 1 to 25. Patient variables obtained included: age, race, gender, length of stay, in-hospital mortality and insurance status. Hospital level variables included teaching status, location and region of country. SAS 9.4 software was used for data analysis. Comparisons of variables between hospitalized HIV patients with and without HAND showed significant increase in cost per hospital admissions, longer hospital stay and higher risk of mortality in patients with HAND.

Abstract
Behavioral disorders are common in persons infected with human immunodeficiency virus (HIV). The differential includes preexisting psychiatric diseases, substance abuse, direct effects of HIV infection, opportunistic infection, and the adverse effects of medical therapies. Many patients have more than one contributing or comorbid problem to explain these behavioral changes. The differential should always include consideration of psychosocial, genetic, and medical causes of disease. Treatment strategies must take into account the coadministration of antiretroviral therapy and the specific neurologic problems common in patients infected with HIV.

Abstract
The advent of highly active antiretroviral therapy has prolonged the life expectancy of HIV patients and decreased the number of adults who progress to AIDS and HIV-associated dementia. However, neurocognitive deficits remain a pronounced consequence of HIV/AIDS. HIV-1 infection targets the central nervous system in subcortical brain areas and leads to high rates of delirium, depression, opportunistic central nervous system infections, and dementia. Long-term HIV replication in the brain occurs in astrocytes and microglia, allowing the virus to hide from antiviral medication and later compromise neuronal function. The associated cognitive disturbance is linked to both viral activity and inflammatory and other mediators from these immune cells that lead to the damage associated with HIV-associated neurocognitive disorders, a general term given for these disturbances. We review the severity and prevalence of the neuropsychiatric complications of HIV including delirium, neurobehavioral impairments (depression), minor cognitive-motor dysfunction, and HIV-associated dementia.

Abstract
Persons over age 50 are not only aging with human immunodeficiency virus (HIV) infection but also represent a high proportion of new HIV infections. Neuropsychiatric symptoms, including depression, cognitive impairment, and substance abuse, are very common in individuals infected with HIV. However, there is little understanding of the relationship between these HIV-related comorbid conditions in newly infected elderly patients compared to uninfected elderly and those who have survived after 20 years of HIV/AIDS. We summarize the current theories and research that link aging and HIV with psychiatric illnesses and identify emerging areas for improved research, treatment, and patient care.

Abstract
HIV infection remains a major world health problem more than 20 years after discovery of the virus. Mental disorders make individuals more vulnerable to behaviors that transmit HIV and interfere with HIV treatment adherence. The evidence supporting the need for optimal provision of mental health care in HIV clinics is mounting, along with evidence that these disorders can be treated successfully. Disorders of mental life include brain diseases (eg, depression, bipolar disorder, schizophrenia, and dementia), personality disorders, addictions, and psychologic disruptions, which contribute to the spread of the virus through their influence on behavior. However, although evidence exists that successful treatment of co-occurring mental disorders leads to improved HIV outcomes, integrated mental health care in HIV clinics remains grossly suboptimal.

Abstract
Little is known about the type and frequency of psycho-organic syndromes among prisoners. We report the case of a 20-year-old African HIV-I-positive male asylum seeker who developed increasingly bizarre behaviour in prison. The observation of complex behavioural disturbances with a hallucinatory-delusional state led to the diagnosis of delirium caused by AIDS-defining tuberculous meningoencephalitis. The patient improved with specific, symptomatic treatment. This case illustrates the difficulties in diagnosis when communication is impeded. Scrupulous differential diagnosis is necessary for all prisoners manifesting behavioural disturbances. We discuss the pathogenesis and diagnostic procedures of tuberculous meningoencephalitis.
