The Probability of A1C Goal Attainment in Patients With Uncontrolled Type 2 Diabetes in a Large Integrated Delivery System: A Prediction Model.

OBJECTIVE: To assess patient characteristics and treatment factors associated with uncontrolled type 2 diabetes (T2D) and the probability of hemoglobin A1c (A1C) goal attainment. RESEARCH DESIGN AND METHODS: This was a retrospective cohort study using the electronic health record at Cleveland Clinic. Patients with uncontrolled T2D (A1C >9%) were identified on the index date of 31 December 2016 (n = 6,973) and grouped by attainment (n = 1,653 [23.7%]) or nonattainment (n = 5,320 [76.3%]) of A1C <8% by 31 December 2017, and subgroups were compared on a number of demographic and clinical variables. On the basis of these variables, a nomogram was created for predicting probability of A1C goal attainment. RESULTS: For the entire population, median age at index date was 57.7 years (53.3% male), and the majority were white (67.2%). Median A1C was 10.2%. Obesity (50.6%), cardiovascular disease (46.9%), and psychiatric disease (61.1%) were the most common comorbidities. Metformin (62.7%) and sulfonylureas (38.7%) were the most common antidiabetes medications. Only 1,653 (23.7%) patients achieved an A1C <8%. Predictors of increased probability of A1C goal attainment were older age, white/non-Hispanic race/ethnicity, Medicare health insurance, lower baseline A1C, higher frequency of endocrinology/primary care visits, dipeptidyl peptidase 4 inhibitor use, thiazolidinedione use, metformin use, glucagon-like peptide 1 receptor agonist use, and fewer classes of antidiabetes drugs. Factors associated with lower probability included insulin use and longer time in the T2D database (both presumed as likely surrogates for duration of T2D). CONCLUSIONS: A minority of patients with an A1C >9% achieved an A1C <8% at 1 year. While most identified predictive factors are nonmodifiable by the clinician, pursuit of frequent patient engagement and tailored drug regimens may help to improve A1C goal attainment.

Natural Language Processing Improves Detection of Nonsevere Hypoglycemia in Medical Records Versus Coding Alone in Patients With Type 2 Diabetes but Does Not Improve Prediction of Severe Hypoglycemia Events: An Analysis Using the Electronic Medical Record in a Large Health System.

OBJECTIVE: To determine if natural language processing (NLP) improves detection of nonsevere hypoglycemia (NSH) in patients with type 2 diabetes and no NSH documentation by diagnosis codes and to measure if NLP detection improves the prediction of future severe hypoglycemia (SH). RESEARCH DESIGN AND METHODS: From 2005 to 2017, we identified NSH events by diagnosis codes and NLP. We then built an SH prediction model. RESULTS: There were 204,517 patients with type 2 diabetes and no diagnosis codes for NSH. Evidence of NSH was found in 7,035 (3.4%) of patients using NLP. We reviewed 1,200 of the NLP-detected NSH notes and confirmed 93% to have NSH. The SH prediction model (C-statistic 0.806) showed increased risk with NSH (hazard ratio 4.44; P < 0.001). However, the model with NLP did not improve SH prediction compared with diagnosis code-only NSH. CONCLUSIONS: Detection of NSH improved with NLP in patients with type 2 diabetes without improving SH prediction.

Physician and Patient Knowledge of Safety and Safe Use Information for Aflibercept in Europe: Evaluation of Risk-Minimization Measures.

BACKGROUND: As part of the risk-management plan for aflibercept in the European Union, materials have been developed to educate physicians and patients in Europe on the safe use of aflibercept. OBJECTIVES: The objectives of this study were to measure receipt of the educational materials and to evaluate understanding of key safety information for aflibercept. METHODS: An observational cross-sectional study among physicians and patients with recent aflibercept experience in France, Germany, Italy, Spain, and the UK was conducted. Eligible physicians and patients completed a brief questionnaire regarding their knowledge of key safety information. RESULTS: Among the 8424 physicians invited to participate in the survey, 428 physicians were eligible, completed the questionnaire, and were included in this analysis. Most physicians reported having received the aflibercept summary of product characteristics (87%) and prescriber guide (77%); approximately half reported receiving the injection procedure video (50%) and patient booklet (54%). Physician knowledge of the most important topics (i.e., side effects; preparing patients for aflibercept injection) was high. Physician knowledge of dosing was high for neovascular (wet) age-related macular degeneration and lower for less commonly prescribed indications. Most physicians knew the contraindications for aflibercept and recognized possible side effects. Among the 874 patients approached about participation in the study, 773 patients were eligible, completed the questionnaire, and were included in the analysis. Patients' reported receipt was relatively low for the aflibercept patient booklet (38%) and the audio CD (23%). Patient knowledge of the health conditions to discuss with a doctor prior to injection was generally high; knowledge about possible side effects varied. Most patients knew that they should speak to a physician immediately if they experienced a possible side effect of aflibercept. CONCLUSION: Most physicians reported receiving the summary of product characteristics, prescriber guide, and patient booklet; half reported receiving the intravitreal injection procedure video. Patient receipt of the educational material was variable. Observed patterns of knowledge indicated the greatest knowledge of the most important risks emphasized in the educational material and lower knowledge of more complex or less salient aspects of safe use.

Evaluation of Physician Knowledge of the Key Safety Information for Aflibercept in Canada: Evaluation of Risk-Minimization Measures.

BACKGROUND: As part of the risk-management plan (RMP) for aflibercept, materials have been developed to educate physicians in Canada on the key safety information and safe use for aflibercept. OBJECTIVE: The objectives of this study were to assess whether physicians in Canada received and reviewed the aflibercept educational materials (i.e. vial preparation instruction card, intravitreal injection procedure video, and product monograph) and to evaluate their knowledge of key safety information. METHODS: Retinal specialists and ophthalmologists who prescribe and/or administer aflibercept were recruited to complete a survey. Physicians could complete and return a paper questionnaire by mail or complete the questionnaire online via a study website. RESULTS: Of the 308 physicians invited to participate in the survey, 95 (31%) completed the questionnaire. Nearly all physicians (98%) reported receiving at least one of the educational materials. The proportion of correct responses to individual questions on storage and preparation of aflibercept ranged from 54 to 98%. Physician knowledge was high on the recommended dose of aflibercept (91%), dose preparation (91-96% on individual items), and dosing guidelines (75-95% on individual items). Most physicians knew the contraindications for aflibercept (89%) and that aflibercept should not be used in pregnancy unless clearly indicated by medical need in which benefits outweigh risks (60%); 21% responded more conservatively that aflibercept should never be used in pregnancy. Knowledge was high for most questions about injection procedures (91-99% on individual items); however, fewer physicians (24%) correctly reported that the eye should be covered with a sterile drape. Knowledge was high for possible side effects (89-100% on individual items) and actions to take in relation to the potential for increased intraocular pressure (86-93% on individual items). CONCLUSION: Nearly all physicians (98%) reported having received the product monograph, and most (82%) reported having received the vial preparation instruction card; nearly half (46%) reported having received the intravitreal injection procedure video. Physicians' knowledge of the most important topics was high. Knowledge varied for topics that are less frequently encountered (e.g. use in women of childbearing potential) and for recommendations that are not standard medical practice in Canada (e.g. use of sterile drape).

The Resulting Variation in Nutrient Intake With the Inclusion of Walnuts in the Diets of Adults at Risk for Type 2 Diabetes: A Randomized, Controlled, Crossover Trial.

PURPOSE: We previously demonstrated that including walnuts in the diets of adults at risk for type 2 diabetes mellitus (T2DM) led to improved overall diet quality. This report examines the specific changes in their nutrient intake. DESIGN: This was a randomized, controlled, modified Latin square parallel design trial with 2 treatment arms. Participants were randomized to walnut intake with, or without, dietary advice to regulate caloric intake. Within each treatment arm, they were further randomized to one of 2 sequence permutations (walnut-included/walnut-excluded or walnut-excluded/walnut-included diet), with a 3-month washout between treatment phases. SETTING: Community hospital in Lower Naugatuck Valley in Connecticut. PARTICIPANTS: Cohort of 112 participants (31 men and 81 women) at risk for T2DM. INTERVENTION: Participants included 56 g (366 kcal) of walnuts in their daily diets for 6 months. MEASURES: Nutrient intake was assessed using web-based Automated Self-Administered 24-Hour Dietary Assessment. ANALYSIS: Data were analyzed using generalized linear models. RESULTS: Walnut inclusion led to increased intake of total fat, calcium, magnesium, thiamin, total saturated fatty acids, and monounsaturated and polyunsaturated fatty acids (379.0 ± 90.3 g vs -136.5 ± 92.7 g, P < .01; 230.7 ± 114.2 mg vs -95.2 ± 117.4 mg, P = .05; 111.0 ± 33.9 mg vs -32.3 ± 34.9 mg, P < .01; 0.28 ± 0.2 mg vs -0.47 ± 0.2 mg, P = .02; 8.6 ± 3.4 g vs -1.1 ± 3.5 g, P =.05; 6.3 ± 3.9 g vs -6.3 ± 4.0 g, P = .03; and 25.4 ± 4.0 vs -6.6 ± 4.2 g, P < .01, respectively). Vitamin C intake decreased (-65.3 ± 55.3 mg vs 98.9 ± 56.8 mg, P = .04). Protein intake increased from baseline with the inclusion of walnuts (20.0 ± 8.8 g, P < .05). Walnut inclusion led to an increase in total calories consumed when caloric intake is not regulated. CONCLUSION: Including walnuts in the diets of these adults led to increased dietary intake of some nutrients associated with lower risk of developing T2DM and other cardiometabolic risk factors.

Mid-arm muscle area and anthropometry predict low birth weight and poor pregnancy outcomes in Tanzanian women with HIV.

BACKGROUND: An observational study was conducted to examine the role of maternal anthropometry, including mid-arm muscle area (MAMA) and others, as risk factors for low birth weight (LBW), small for gestational age (SGA) and preterm births in human immunodeficiency virus (HIV) infected pregnant women. HIV-positive women (N = 2369), between 12 and 32 weeks gestation were followed through delivery in Tanzania, from 2003 to 2008. Participants were women enrolled in a randomized, double-blind, placebo-controlled, clinical trial who delivered live births. METHODS: Binomial regression analysis was used to evaluate the association of maternal nutritional indicators of MAMA, mid-upper arm circumference (MUAC), body mass index (BMI) and maternal weight with LBW, SGA and preterm in multivariate analysis. RESULTS: Higher MAMA was associated with a 32% lower risk of LBW compared to lower measurements (RR = 0.68, 95% CI = 0.50-0.94). Similar protective associations were noted for higher BMI (RR = 0.58, 95% CI = 0.42-0.79); maternal weight (RR = 0.50, 95% CI = 0.36-0.69) and MUAC (RR = 0.62, 95% CI = 0.45-0.86). Higher MAMA was also associated with lower risk of SGA (RR = 0.78, 95% CI = 0.68-0.90) and marginally associated with preterm (RR = 0.85, 95% CI = 0.69-1.04). Beneficial associations of MUAC, BMI and maternal weight with SGA and preterm were also observed. CONCLUSION: MAMA performs comparably to MUAC, maternal weight and BMI, as a predictor of LBW and SGA in HIV-infected women. The possible role of MAMA and other indicators in screening HIV positive women at risk of adverse pregnancy outcomes should be investigated.

Teaching residents to put patients first: creation and evaluation of a comprehensive curriculum in patient-centered communication.

BACKGROUND: Patient-centered communication is essential for successful patient encounters and positive patient outcomes. Therefore, training residents how to communicate well is one of the key responsibilities of residency programs. However, many residents, especially international medical graduates, continue to struggle with communication barriers. METHODS: All residents and faculty from a small community teaching hospital participated in a three-year, multidimensional patient-centered communication curriculum including communication training with lectures, experiential learning, communication skills practice, and reflection in the areas of linguistics, physician-patient communication, cultural & linguistically appropriate care, and professionalism. We evaluated the program through a multipronged outcomes assessment, including self-assessment, scores on the Calgary-Cambridge Scale during Objective Structured Clinical Examination (OSCE), a survey to measure the hidden curriculum, English Communication Assessment Profile (E-CAP),, the Maslach Burnout-Inventory (MBI), and residents' evaluation of faculty communication. RESULTS: Sixty-two residents and ten faculty members completed the three-year curriculum. We saw no significant changes in the MBI or hidden curriculum survey. Communication skills as measured by Calgary Cambridge Score, E-CAP, and resident communication improved significantly (average Calgary-Cambridge Scale scores from 70% at baseline to 78% at follow-up (p-value < 0.001), paired t-test score from 68% at baseline to 81% at follow-up (p-value < 0.004), average E-CAP score from 73 to 77% (p-value < 0.001)). Faculty communication and teaching as rated by residents also showed significant improvement in four out of six domains (learning climate (p < 0.001), patient-centered care (p = 0.01), evaluation (p = 0.03), and self-directed learning (p = 0.03)). CONCLUSION: Implementing a multidimensional curriculum in patient-centered communication led to modest improvements in patient-centered communication, improved language skills, and improved communication skills among residents and faculty.

Inclusion of walnut in the diets of adults at risk for type 2 diabetes and their dietary pattern changes: a randomized, controlled, cross-over trial.

BACKGROUND: In our recently published study, including walnuts in the diets of adults with prediabetes led to overall improvement in diet quality. This report adds to those study findings by examining the food groups displaced during walnut inclusion in the diets of those adults with prediabetes. METHODS: Randomized, controlled, modified Latin square parallel design with 2 treatment arms. The 112 participants (31 men, 81 women) were randomly assigned to a diet with or without dietary counseling to regulate calorie intake in a 1:1 ratio. Within each treatment arm, participants were further randomized to 1 of 2 sequence permutations to receive a walnut-included diet with 56 g (366 kcal) of walnuts per day and a walnut-excluded diet. Participants in the calorie-regulated arm received advice from a dietitian to preserve an isocaloric condition while including walnuts. We analyzed the 12 components of the 2010 Healthy Eating Index to examine dietary pattern changes of study participants. RESULTS: Seafood and plant protein foods intake significantly increased with walnut inclusion, compared with their exclusion (2.14±2.06 vs -0.49±2.33; p=0.003). The ingestion of healthful fatty acids also significantly increased with walnut inclusion, compared with their exclusion (1.43±4.53 vs -1.76±4.80; p=0.02). Dairy ingestion increased with walnut inclusion in the calorie-regulated phase, compared with walnut inclusion without calorie regulation (1.06±4.42 vs -2.15±3.64; p=0.02). CONCLUSIONS: Our data suggest that walnut inclusion in the diets of adults at risk for diabetes led to an increase in intake of other healthful foods. TRIAL REGISTRATION NUMBER: NCT02330848.

Baby hamster kidney cell-derived recombinant factor VIII: a quarter century of learning and clinical experience.

INTRODUCTION: Management and care of individuals with hemophilia A advanced immensely with the introduction of recombinant factor VIII (rFVIII) replacement products. This review provides a historical overview of rFVIII development with a focus on Bayer's rFVIII (with albumin) and sucrose-formulated rFVIII (rFVIII-FS), the only rFVIII products cloned in baby hamster kidney (BHK) cells with >25 years of proven safety and efficacy. Areas covered: We review the advances in rFVIII technology and the efficacy and safety data for BHK-derived rFVIII/rFVIII-FS from clinical trials, investigator-initiated studies, and observational studies. Innovative products with new treatment potentials (eg, BAY 81-8973 and BAY 94-9027) built on this established safety and efficacy profile are also briefly discussed. The literature search strategy included targeted searches (PubMed) with manual article selection and other product-specific searches. Expert commentary: Development of rFVIII products and related improvements in viral safety and manufacturing efficiency have guaranteed an adequate supply of factor products worldwide and increased prophylaxis use. The net effects have been joint health preservation, reduction in morbidity and mortality, and quality-of-life enhancements. Current treatment challenges include lack of adherence to prophylaxis and inhibitor development; extended-half-life rFVIII products and non-FVIII replacement therapies in development may help overcome these challenges.

Lifestyle medicine curriculum for a preventive medicine residency program: implementation and outcomes.

BACKGROUND: The vast majority of the healthcare problems burdening our society today are caused by disease-promoting lifestyles (e.g., physical inactivity and unhealthy eating). Physicians report poor training and lack of confidence in counseling patients on lifestyle changes. OBJECTIVE: To evaluate a new curriculum and rotation in lifestyle medicine for preventive medicine residents. METHODS: Training included didactics (six sessions/year), distance learning, educational conferences, and newly developed lifestyle medicine rotations at the Institute of Lifestyle Medicine, the Yale-Griffin Prevention Research Center, and the Integrative Medicine Center. We used a number of tools to assess residents' progress including Objective Structured Clinical Examinations (OSCEs), self-assessments, and logs of personal health habits. RESULTS: A total of 20 residents participated in the lifestyle medicine training between 2010 and 2013. There was a 15% increase in residents' discussions of lifestyle issues with their patients based on their baseline and follow-up surveys. The performance of preventive medicine residents on OSCEs increased each year they were in the program (average OSCE score: PGY1 73%, PGY2 83%, PGY3 87%, and PGY4 91%, p=0.01). Our internal medicine and preliminary residents served as a control, since they did participate in didactics but not in lifestyle medicine rotations. Internal medicine and preliminary residents who completed the same OSCEs had a slightly lower average score (76%) compared with plural for resident, preventive medicine residents (80%). However, this difference did not reach statistical significance (p=0.11). CONCLUSION: Incorporating the lifestyle medicine curriculum is feasible for preventive medicine training allowing residents to improve their health behavior change discussions with patients as well as their own personal health habits.

Determinants of Anemia Among Human Immunodeficiency Virus-Positive Adults at Care and Treatment Clinics in Dar es Salaam, Tanzania.

Anemia is often a comorbidity of human immunodeficiency virus (HIV) infection. Many cross-sectional studies have been conducted on anemia and HIV, but few, if any, have addressed incidence of anemia prospectively. A longitudinal analysis was conducted in 48,068 nonpregnant HIV-infected adults in Dar es Salaam, Tanzania, seen at Management and Development for Health-U.S. President's Emergency Plan for AIDS Relief HIV care and treatment programs between 2004 and 2011. Almost 56% (N = 27,184) of study participants had anemia (hemoglobin < 11 g/dL) at the time of enrollment at the clinic. Female gender, low body mass index (BMI), low CD4 T-cell count, high levels of liver enzyme alanine aminotransferase, antiretroviral treatment (ART) regimens, and concurrent tuberculosis treatment were all independently significantly associated with an increased risk of anemia. Low BMI and low CD4 T-cell count were independently significantly associated with an increased risk for iron deficiency anemia (IDA). Higher BMI status and ART use were associated with recovery from anemia. Anemia, including IDA, is a comorbidity that is associated with other adverse consequences (e.g., low BMI and CD4 T-cell count) among individuals with HIV infection, including those on ART. Interventions to prevent anemia and its complications need to be examined in the context of future studies.

Walnut ingestion in adults at risk for diabetes: effects on body composition, diet quality, and cardiac risk measures.

BACKGROUND: Despite their energy density, walnuts can be included in the diet without adverse effects on weight or body composition. The effect of habitual walnut intake on total calorie intake is not well studied. Effects on overall diet quality have not been reported. METHODS: Randomized, controlled, modified Latin square parallel design study with 2 treatment arms. The 112 participants were randomly assigned to a diet with or without dietary counseling to adjust calorie intake. Within each treatment arm, participants were further randomized to 1 of the 2 possible sequence permutations to receive a walnut-included diet with 56 g (providing 366 kcal) of walnuts per day and a walnut-excluded diet. Participants were assessed for diet quality, body composition, and cardiac risk measures. RESULTS: When compared with a walnut-excluded diet, a walnut-included diet for 6 months, with or without dietary counseling to adjust caloric intake, significantly improved diet quality as measured by the Healthy Eating Index 2010 (9.14±17.71 vs 0.40±15.13; p=0.02 and 7.02±15.89 vs -5.92±21.84; p=0.001, respectively). Endothelial function, total and low-density lipoprotein (LDL) cholesterol improved significantly from baseline in the walnut-included diet. Body mass index, percent body fat, visceral fat, fasting glucose, glycated hemoglobin, and blood pressure did not change significantly. CONCLUSIONS: The inclusion of walnuts in an ad libitum diet for 6 months, with or without dietary counseling to adjust calorie intake, significantly improved diet quality, endothelial function, total and LDL cholesterol, but had no effects on anthropometric measures, blood glucose level, and blood pressure. TRIAL REGISTRATION NUMBER: NCT02330848.

Effect of multivitamin supplements on weight gain during pregnancy among HIV-negative women in Tanzania.

Multivitamin supplementation has been shown to reduce the risk of low birthweight. This effect could be mediated through gestational weight gain. However, the effect of multivitamin supplementation on weight gain during pregnancy has not been fully studied. The objective of this study was to examine the effects of multivitamins on pregnancy weight gain. We enrolled 8468 HIV-negative women from Dar es Salaam, Tanzania, in a randomised, placebo-controlled trial of multivitamins on birth outcomes. Women were randomly assigned to receive either a daily oral dose of multivitamin tablets or a placebo and were weighed every 4 weeks from enrolment until the last visit before delivery. Intent-to-treat analyses were carried out to examine the effects of multivitamins on pregnancy weight gain. Multivariate linear and binomial regression models with the log-link function were used to examine the association of weight gain during pregnancy to birthweight. The overall total weight gain was 253 g (SE: 69, P: 0.0003) more, while the overall 4 weekly weight gain was 59 g greater (SE: 18, P: 0.005) among women who received multivitamins compared to placebo. Women in the lowest quartile of gestational weight gain had babies with an average birthweight of 3030 g (SD: 524), while women in the highest quartile had babies weighing 3246 g (SD: 486), on average. Prenatal multivitamin supplements increased gestational weight gain, which was a significant predictor of birthweight.

Providers role in colonoscopy screening for colorectal cancer.

OBJECTIVES: To examine predictors of provider recommendations for colorectal cancer (CRC). METHODS: We examined proportions of patients without prior screening for colonoscopy and their willingness to get a colonoscopy if recommended by a healthcare provider. RESULTS: The rate of CRC screening with a colonoscopy within the recommended guidelines was 35%; provider recommendation rate for colonoscopy screening was 34.9%; and never-screened patients would receive a colonoscopy 78% when recommended by a provider. Provider recommendation was the best predictor for receiving a screening colonoscopy (OR 4.19; 95% CI, 1.91-9.22, p < .01). CONCLUSIONS: Physician recommendation for colonoscopy is the most effective strategy to promote screening colonoscopy in the US, but only one third of eligible patients recall such counseling.

Can the inpatient hospital setting be a golden opportunity to improve colon cancer screening rates in the United States?

BACKGROUND: Colorectal cancer is the third most common cancer in the United States. Despite efforts to increase colorectal cancer screening, the rate of compliance with the recommended screening remains relatively suboptimal according the American Cancer Society (53%). PURPOSE: To assess whether the time of hospitalization is a suitable opportunity for patients to receive counseling and for recruiting patients to undergo screening colonoscopy for colon cancer. METHOD: In 2009, we conducted a cross-sectional survey of hospitalized adults age 50 to 80 years in order to assess their responses on a modified version of the Health Information National Trends Survey. We conducted χ(2) analyses on these data to examine the differences in patients' knowledge of colorectal cancer screening and prior adherence to screening guidelines and to assess whether they would be willing to undergo a screening in the near future if prompted by their physicians. RESULTS: We enrolled a total of 332 participants to complete the study questionnaire. About 94% of the subjects had heard about colon cancer, and 83.4% had heard of any screening tests to detect colorectal cancer. About 66% of subjects reported the colonoscopy to be the most effective screening test for colon cancer. Approximately 55% of the total sample group adhered to recommended screening guidelines for colon cancer using the colonoscopy. CONCLUSIONS: The time of hospitalization is a potential "golden opportunity" to counsel patients and promote colon cancer screening.

Symptoms of anxiety, depression, and posttraumatic stress among survivors of the 2005 Pakistani earthquake.

OBJECTIVES: To assess and compare the prevalence of psychological morbidity among survivors of the 2005 northern Pakistan earthquake from Azad Kashmir and the Northwest Frontier Province (NWFP). METHODS: We conducted a cross-sectional study among randomly sampled survivors (N = 361) of the earthquake living in camps at the time of the interview, approximately 6 months after the earthquake. RESULTS: The prevalence of posttraumatic stress disorder (PTSD) symptoms in the total sample was 51.5% and the prevalence of individuals who received positive scores on the Hopkins Symptom Checklist (HSCL) was 75%. The prevalence rates for anxiety and depression symptoms were 77.3% and 70.9%, respectively. The prevalence in Azad Kashmir was 57.9% for PTSD and 79.8% for positive HSCL, and NWFP had 41.3% PTSD and 67.4% positive HSCL. Study subjects from Azad Kashmir were approximately 2 times as likely to have PTSD or a positive HSCL when compared to subjects from NWFP (odds ratio 1.95, confidence interval 1.27-3.0; P = .0024) and (odds ratio 1.91, confidence interval 1.18-3.1; P = .0085), respectively. CONCLUSIONS: Nearly half of the northern Pakistan earthquake survivors had symptoms of PTSD. Six months after the incident, more than three-fourths exhibited symptoms of an anxiety disorder.

Predictors of breastfeeding cessation among HIV-infected women in Dar es Salaam, Tanzania.

This paper examines predictors of breastfeeding cessation among a cohort of human immunodeficiency virus (HIV)-infected women. This was a prospective follow-up study of HIV-infected women who participated in a randomized micronutrient supplementation trial conducted in Dar es Salaam, Tanzania. 795 HIV-infected Tanzanian women with singleton newborns were utilized from the cohort for this analysis. The proportion of women breastfeeding declined from 95% at 12 months to 11% at 24 months. The multivariate analysis showed breastfeeding cessation was significantly associated with increasing calendar year of delivery from 1995 to 1997 [risk ratio (RR), 1.36; 95% confidence interval (CI) 1.13-1.63], having a new pregnancy (RR 1.33; 95% CI 1.10-1.61), overweight [body mass index (BMI) ≥25 kg m(-2) ; RR 1.37; 95% CI 1.07-1.75], underweight (BMI <18.5kg m(-2) ; RR 1.29; 95% CI 1.00-1.65), introduction of cow's milk at infant's age of 4 months (RR 1.30; 95% CI 1.04-1.63). Material and social support was associated with decreased likelihood of cessation (RR 0.83; 95% CI 0.68-1.02). Demographic, health and nutritional factors among women and infants are associated with decisions by HIV-infected women to cease breastfeeding. The impact of breastfeeding counselling programs for HIV-infected African women should consider individual maternal, social and health contexts.

Pneumocystis jiroveci pneumonia in patients with AIDS in the inner city: a persistent and deadly opportunistic infection.

Highly active antiretroviral therapy (HAART) has decreased the morbidity and mortality of opportunistic infections including Pneumocystis jiroveci pneumonia (PCP) among HIV-infected individuals. We performed a hospital-based retrospective cohort study among a population of medically underserved inner city persons living in Atlanta, Georgia, diagnosed with confirmed PCP to compare the epidemiology and outcomes of PCP during 2 defined periods: 1990 to 1995, or pre-HAART period, and 1996 to 2001, or HAART period. A total of 488 patients were available for analysis. The overall mortality rate was 47% during the pre-HAART era compared with 37% during the HAART era (P = 0.02). However, among those patients that required medical intensive care unit admission and mechanical ventilation, the mortality rate was particularly high, with over 80% of patients dying as a result of their episode of PCP during both periods. PCP was the initial presentation of HIV infection in 39.3% in the pre-HAART period with a mortality rate of 52%, in contrast with 37% in the HAART period, with a mortality rate of 45%, respectively (P = NS). Only 30.7% in the pre-HAART period and 31.1% of patients in the HAART period were receiving PCP prophylaxis. The overall risk of death, when we combined both groups in the analysis, was higher for those patients who did not take PCP prophylaxis, those who smoked tobacco, and those who were admitted to the medical intensive care unit and required mechanical ventilatory support. Our findings suggest that despite the availability of HAART, PCP continues to cause a significant burden of disease among inner-city HIV-infected populations.

Iron status is an important cause of anemia in HIV-infected Tanzanian women but is not related to accelerated HIV disease progression.

In HIV-infected populations from developing countries, it is unclear what proportion of anemia is attributable to iron deficiency (ID) and whether high body iron stores worsen HIV disease progression. We therefore evaluated these research questions in 584 HIV-infected Tanzanian women. Hemoglobin (Hb), serum ferritin (SF), serum transferrin receptor (sTfR), and C-reactive protein (CRP) concentrations were evaluated between 13 and 43 wk after women gave birth. ID was defined as SF or sTfR outside normal ranges, and ID anemia (IDA) as ID plus low Hb. In multivariate Cox regression models, the association between SF and HIV disease progression was assessed. Participants received iron + folate supplements during pregnancy. Hb (r = -0.159; P = 0.0001), SF (r = 0.355; P < 0.0001), and sTfR/log SF index (r = -0.119; P = 0.004) were related to CRP, whereas sTfR (r = 0.029; P = 0.48) was not. Prevalence estimates were 39.7% for ID and 23.6% for IDA. ID was associated with 48.9% of anemia cases. Categories of SF were not significantly associated with HIV-related mortality or progression to stage 4. Nevertheless, SF > 150.0 microg/L was related to a nonsignificantly elevated risk of progression to stage 4 (rate ratio = 1.78; 95% CI = 0.68-4.64; P = 0.24) compared with SF < 12.0 microg/L. In HIV-infected, parous women from sub-Saharan Africa, ID is of moderately high prevalence and is an important underlying cause of anemia. High storage iron does not appear to be related to HIV disease progression in this population, but more research on the role of iron during HIV disease is needed.

Vitamins and perinatal outcomes among HIV-negative women in Tanzania.

BACKGROUND: Prematurity and low birth weight are associated with high perinatal and infant mortality, especially in developing countries. Maternal micronutrient deficiencies may contribute to these adverse outcomes. METHODS: In a double-blind trial in Dar es Salaam, Tanzania, we randomly assigned 8468 pregnant women (gestational age of fetus, 12 to 27 weeks) who were negative for human immunodeficiency virus infection to receive daily multivitamins (including multiples of the recommended dietary allowance) or placebo. All the women received prenatal supplemental iron and folic acid. The primary outcomes were low birth weight (<2500 g), prematurity, and fetal death. RESULTS: The incidence of low birth weight was 7.8% among the infants in the multivitamin group and 9.4% among those in the placebo group (relative risk, 0.82; 95% confidence interval [CI], 0.70 to 0.95; P=0.01). The mean difference in birth weight between the groups was modest (67 g, P<0.001). The rates of prematurity were 16.9% in the multivitamin group and 16.7% in the placebo group (relative risk, 1.01; 95% CI, 0.91 to 1.11; P=0.87), and the rates of fetal death were 4.3% and 5.0%, respectively (relative risk, 0.87; 95% CI, 0.72 to 1.05; P=0.15). Supplementation reduced both the risk of a birth size that was small for gestational age (<10th percentile; 10.7% in the multivitamin group vs. 13.6% in the placebo group; relative risk, 0.77; 95% CI, 0.68 to 0.87; P<0.001) and the risk of maternal anemia (hemoglobin level, <11 g per deciliter; relative risk, 0.88; 95% CI, 0.80 to 0.97; P=0.01), although the difference in the mean hemoglobin levels between the groups was small (0.2 g per deciliter, P<0.001). CONCLUSIONS: Multivitamin supplementation reduced the incidence of low birth weight and small-for-gestational-age births but had no significant effects on prematurity or fetal death. Multivitamins should be considered for all pregnant women in developing countries. (ClinicalTrials.gov number, NCT00197548 [ClinicalTrials.gov].).
