The impact of the housing status on clinical outcomes and health care utilization among individuals living with HIV

ABSTRACT

The lack of stable housing can impair access and continuity of care for patients living with human immunodeficiency virus (HIV). This study investigated the relationship between housing status assessed at multiple time points and several core HIV-related outcomes within the same group of HIV patients experiencing homelessness. Patients with consistently stable housing (CSH) during the year were compared to patients who lacked CSH (non-CSH group). The study outcomes included HIV viral load (VL), CD4 counts, and health care utilization. Multivariable and propensity weighted analyses were used to assess outcomes adjusting for potential group differences. Of 208 patients, 88 (42%) had CSH and 120 (58%) were non-CSH. Patients with CSH had significantly higher proportion of VL suppression and higher mean CD4 counts. The frequency of nurse visits in the CSH group was less than a half of that in the non-CSH group. Patients with CSH were less likely to be admitted to the medical respite facility, and if admitted, their length of stay was about a half of that for the non-CSH group. Our study findings show that patients with CSH had significantly better HIV virologic control and immune status as well as improved health care utilization.     

Relevance of Cosmeceuticals to the Dermatologic Surgeon

Background. The dermatologic surgeon is the dermatologist with special expertise in the surgical care of the health and beauty of the skin.
Objectives, Methods, Results. There is no better arena for the use of topical regimens to preserve skin quality than in the time interval devoted to before and after care with respect to surgical procedures.
Conclusion. Many of these regimens can be tailor devised with topical drugs and cosmeceuticals together in proper balance in the patient's best interest for affordable health care.

Mapping out a search for environmental causes of breast cancer.

Geographic patterns and time trends for breast cancer suggest there are preventable causes that may include environmental factors. This article describes the development of new methods used in the Cape Cod Breast Cancer and Environment Study to investigate whether synthetic chemicals in the environment contribute to breast cancer risk.

Adult daughters and parent care: a comparison of one-, two- and three-generation households.

This paper compares the effects of parent-care associated with three living arrangements of elderly widowed mothers who were being helped by married daughters: elderly mother living separately; two-generation households (mothers, daughters, sons-in-law); and three-generation households (grandchildren present). Daughters whose mothers lived separately fared the best; their mothers were the most cognitively and functionally capable and the daughters reported the fewest negative effects of caregiving. Daughters in two-generation households provided the most care; their mothers were the oldest and most impaired. Since daughters in three-generation households reported more negative mental and emotional effects of care, the unique problems of caregiving in such households are discussed.

Pathophysiology of congenital diaphragmatic hernia. III: Exogenous surfactant therapy for the high-risk neonate with CDH.

Exogenous surfactant therapy (EST) in surfactant-deficient premature infants has been shown to improve lung compliance, decrease morbidity, and improve survival. Reports have demonstrated that newborns with congenital diaphragmatic hernia (CDH) have lung compliance, pressure-volume curves, and hyaline membrane formation resembling those changes seen in surfactant deficient premature newborns. We hypothesize that EST may also benefit infants with CDH. All high risk cases of prenatally diagnosed CDH at Children's Hospital of Buffalo from November 1988 to February 1991 were prospectively evaluated for EST. In those families who chose to participate, the surfactant preparation, Infasurf (100 mg/kg), was instilled into the newborn's lungs prior to the first breath. The remainder of the perinatal, neonatal, and surgical care was performed in a routine manner. Three high-risk prenatally diagnosed newborns with left CDH were treated with EST. All showed signs of decreased pulmonary compliance, but could still be adequately oxygenated and ventilated. Surgical correction was performed after stabilization and all required patch closures. Two of the three infants suffered no life-threatening episodes of pulmonary hypertension and all survived. These infants had many known indicators for poor outcome in CDH with an expected survival of less than 20%. We believe that EST in these neonates with CDH contributed to their survival with minimum morbidity. These results suggest that surfactant replacement for the high-risk neonate with CDH warrants further consideration and a randomized clinical trial is being planned.
