RESUMEN
The cause of death in people affected by sickle cell disease (SCD) is often challenging to define as prior studies have used retrospective or administrative data for analysis. We used a prospective longitudinal registry to assess mortality and clinical co-morbidities among subjects enrolled in the Sickle Cell Disease Implementation Consortium (SCDIC) registry. At enrollment, we collected the following data: patient-reported demographics, SCD phenotype, baseline laboratory values, comorbidities, and current medications. Subjects were followed for a median of 4.7 years before the present analysis. The relationship of clinical co-morbidities (at time of enrollment) to mortality was determined using survival analysis, adjusting for SCD phenotype and gender. There was a total of 2439 people with SCD enrolled in the SCDIC registry. One hundred and twenty-eight participants (5%) died during the observation period (2017-2022). Six people died from trauma and were excluded from further analysis. Proximate cause of death was unwitnessed in 17% of the deaths, but commonest causes of death include cardiac (18%), acute chest or respiratory failure (11%), sudden unexplained death (8%). Enrollment characteristics of the individuals who died (n = 122) were compared to those of survivors (n = 2317). Several co-morbidities at enrollment increased the odds of death on univariate analysis. All co-morbidities were included in a multivariable model. After backward elimination, iron overload, pulmonary hypertension, and depression, remained statistically significant predictors of the risk of death. SCD reduces life expectancy. Improved comprehensive and supportive care to prevent end-organ damage and address comorbidities is needed for this population.

Objectives: To describe the presence and persistence of neurological and neuropsychological sequelae among children with acquired Zika virus infection and assess whether those sequelae were more common in children infected with Zika virus compared to uninfected children. Methods: We conducted a prospective cohort study of children with and without Zika virus infection in León, Nicaragua, using a standard clinical assessment tool and questionnaire to collect data on symptoms at three visits, about 6 months apart, and a battery of standardized instruments to evaluate neurocognitive function, behavior, depression, and anxiety at the last two visits. Results: Sixty-two children were enrolled, with no significant differences in demographics by infection group. Children infected with Zika virus had a range of neurological symptoms, some of which persisted for 6 to 12 months; however, no consistent pattern of symptoms was observed. At baseline a small percentage of children infected with Zika virus had an abnormal finger-to-nose test (13%), cold touch response (13%), and vibration response (15%) versus 0% in the uninfected group. Neurocognitive deficits and behavioral problems were common in both groups, with no significant differences between the groups. Children infected with Zika virus had lower cognitive efficiency scores at the 6-month visit. Anxiety and depression were infrequent in both groups. Conclusions: Larger studies are needed to definitively investigate the relationship between Zika virus infection and neurological symptoms and neurocognitive problems, with adjustment for factors affecting cognition and behavior, including mood and sleep disorders, home learning environment, history of neuroinvasive infections, and detailed family history of neuropsychological problems.

[RESUMEN]. Objetivos. Describir la presencia y persistencia de secuelas neurológicas y neuropsicológicas en pacientes pediátricos que contrajeron la infección por el virus del Zika y evaluar si dichas secuelas fueron más comunes en los infectados con el virus del Zika en comparación con los no infectados. Métodos. Se realizó un estudio de cohorte prospectivo en pacientes pediátricos con y sin infección por el virus del Zika en León (Nicaragua), con una herramienta de evaluación clínica estándar y un cuestionario para recopilar datos sobre los síntomas en tres visitas, con aproximadamente seis meses de diferencia, y un con- junto de instrumentos estandarizados para evaluar la función neurocognitiva, el comportamiento, la depresión y la ansiedad en las últimas dos visitas. Resultados. Participaron 62 niños y niñas sin diferencias significativas en la demografía por grupo de infección. Los participantes infectados con el virus del Zika mostraron una variedad de síntomas neurológi- cos, algunos de los cuales persistieron entre 6 y 12 meses; no obstante, no se observó un patrón sistemático en los síntomas. Al inicio del estudio, un pequeño porcentaje de participantes infectados con el virus del Zika mostró resultados anormales a las pruebas dedo-nariz (13%), respuesta al tacto (frío) (13%) y respuesta a la vibración (15%), frente a un 0% en el grupo no infectado. Los déficits neurocognitivos y los problemas de comportamiento fueron comunes en ambos grupos, sin diferencias significativas entre los grupos. Los partic- ipantes infectados con el virus del Zika mostraron puntuaciones de eficiencia cognitiva más bajas en la visita a los 6 meses. La ansiedad y la depresión fueron poco frecuentes en ambos grupos. Conclusiones. Son necesarios estudios más amplios para investigar definitivamente la relación entre la infec- ción por el virus del Zika y los síntomas neurológicos y los problemas neurocognitivos, haciendo ajustes para los factores relacionados con la cognición y el comportamiento, incluidos los trastornos del estado de ánimo y el sueño, el entorno de aprendizaje en el hogar, los antecedentes de infecciones neuroinvasivas y los antecedentes familiares detallados de problemas neuropsicológicos.
[RESUMO]. Objetivos. Descrever a presença e a persistência de sequelas neurológicas e neuropsicológicas em crianças com infecção pelo vírus zika e avaliar se essas sequelas foram mais comuns em crianças infectadas pelo vírus zika em comparação com crianças não infectadas. Métodos. Realizamos um estudo de coorte prospectivo em crianças com e sem infecção pelo vírus zika em León, Nicarágua, usando uma ferramenta de avaliação clínica padrão e um questionário para coletar dados de sintomas em três consultas, com cerca de 6 meses de intervalo, além de um conjunto de ferramentas padronizadas para avaliar função neurocognitiva, comportamento, depressão e ansiedade nas duas últimas consultas. Resultados. Foram incluídas 62 crianças, sem diferenças significativas nas características demográficas por grupo de infecção. As crianças infectadas pelo vírus zika tinham uma gama de sintomas neurológicos, alguns dos quais persistiram por 6 a 12 meses. Entretanto, não se observou nenhum padrão consistente de sintomas. No início do estudo, uma pequena porcentagem de crianças infectadas com o vírus zika apresen- tou resultado anormal na prova índex-nariz (13%), resposta ao toque frio (13%) e sensibilidade vibratória (15%), em comparação a 0% no grupo não infectado. Déficits neurocognitivos e problemas comportamentais foram frequentes em ambos os grupos, mas sem diferenças significativas entre eles. As crianças infectadas com o vírus zika tiveram resultados mais baixos de eficiência cognitiva na consulta de 6 meses. Ansiedade e depressão não foram observadas com frequência em ambos os grupos. Conclusões. São necessários estudos mais amplos para investigar a relação exata entre a infecção pelo vírus zika e sintomas neurológicos e problemas neurocognitivos, com ajuste para fatores que afetam a cog- nição e o comportamento, incluindo distúrbios do humor e do sono, ambiente de aprendizagem em casa, história de infecções neuroinvasivas e história familiar detalhada de problemas neuropsicológicos.

Hydroxyurea reduces pain crises, acute chest syndrome, and blood transfusions in sickle cell disease (SCD), but potential detrimental effects on fertility and birth outcomes impede its use. Data on the effects of hydroxyurea taken for SCD during conception and pregnancy are scarce. The Sickle Cell Disease Implementation Consortium collected self-reported pregnancy history, corresponding hydroxyurea use, and pregnancy outcomes in women with SCD in the clinical setting. Among 1285 women 18-45 years of age, 737 (57.4%) reported 1788 pregnancies (1079 live births, 394 miscarriages, 40 stillbirths, 207 abortions, 48 current pregnancies, and 20 missing outcomes) of which 241 (15.9%) live births, miscarriages or stillbirths were conceived while on hydroxyurea. In univariate analyses, pregnancy number more than three, severe sickle genotype, history of stillbirth or miscarriage, and chronic kidney disease at enrollment were covariates significantly associated with a pregnancy ending in miscarriage or stillbirth. After adjustment for covariates and additional SCD severity markers in multivariate analyses, hydroxyurea use during conception and pregnancy, but not during conception only, was associated with an increase in the odds ratio (OR) of miscarriage or stillbirth (OR 2.21, 95% confidence interval [CI] 1.40-3.47). In analyses of live birth outcomes, hydroxyurea use during conception and pregnancy was associated with birth weight < 5.5 pounds in full-term infants (OR 2.98, 95% CI 1.09-7.38) but not with prematurity or serious medical problems at birth. These findings suggest that hydroxyurea use may be safe up to the time of conception, but that clinicians should continue to advise caution regarding use during pregnancy.

Spontaneous coronary artery dissection (SCAD) is a potential precipitant of myocardial infarction and sudden death for which the etiology is poorly understood. Mendelian vascular and connective tissue disorders underlying thoracic aortic disease (TAD), have been reported in ~5% of individuals with SCAD. We therefore hypothesized that patients with TAD are at elevated risk for SCAD. We queried registries enrolling patients with TAD to define the incidence of SCAD. Of 7568 individuals enrolled, 11 (0.15%) were found to have SCAD. Of the sequenced cases (9/11), pathogenic variants were identified (N = 9), including COL3A1 (N = 3), FBN1 (N = 2), TGFBR2 (N = 2), TGFBR1 (N = 1), and PRKG1 (N = 1). Individuals with SCAD had an increased frequency of iliac artery dissection (25.0% vs. 5.1%, p = 0.047). The prevalence of SCAD among individuals with TAD is low. The identification of pathogenic variants in genes previously described in individuals with SCAD, particularly those underlying vascular Ehlers-Danlos, Marfan syndrome, and Loeys-Dietz syndrome, is consistent with prior reports from clinical SCAD series. Further research is needed to identify specific genetic influences on SCAD risk.

RESUMEN
Individuals with sickle cell disease (SCD) experience neurocognitive decline, low medication adherence, increased unemployment, and difficulty with instrumental activities of daily living (IADL). The relationship between self-perceived cognitive difficulties and IADLs, including employment, school enrollment, independence, engagement in leisure activities, and medication adherence is unknown. We hypothesized that self-reported difficulties across neurocognitive areas would predict lower IADL skills. Adolescent and adult participants of the multi-site Sickle Cell Disease Implementation Consortium (SCDIC) (n = 2436) completed patient-reported outcome (PRO) measures of attention, executive functioning, processing speed, learning, and comprehension. Cognitive symptoms were analyzed as predictors in multivariable modeling. Outcome variables included 1) an IADL composite that consisted of employment, participation in school, reliance on others, and leisure pursuits, and 2) hydroxyurea adherence. Participants reported cognitive difficulty across areas of attention (55%), executive functioning (51%), processing speed (57%), and reading comprehension (65%). Executive dysfunction (p < 0.001) and sometimes or often experiencing learning difficulties (p < 0.001 and p = 0.04) and poor comprehension (p = 0.000 and p = 0.001), controlled for age (p < 0.001), pain (p < 0.001), and hydroxyurea use (p = 0.001), were associated with poor IADL skills. Executive functioning difficulties (p = 0.021), controlled for age (p = 0.013 for ages 25-34), genotype (p = 0.001), and hemoglobin (p = 0.004), predicted hydroxyurea non-adherence. Analysis of PRO measures indicated that cognitive dysfunction is prevalent in adolescents and adults with SCD. Cognitive dysfunction translated into clinically meaningful outcomes. PRO of cognitive symptoms can be used as an important adjunct clinical tool to monitor symptoms that impact functional skills, including engagement in societal activities and medication adherence.

Understanding patient experiences, quality of life, and treatment needs in individuals with sickle cell disease (SCD) is essential in promoting health and well-being. We used measures from the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me), Patient Reported Outcomes Measurement Information System (PROMIS), and Quality of Life in Neurological Disorders (NeuroQol) to evaluate pain impact, sleep impact, social functioning, depressive symptoms, tiredness, and cognitive function (collectively, patient reported outcomes [PROs]) and to identify associated demographic and clinical characteristics. Participants (n = 2201) between 18 and 45 years were recruited through the eight Sickle Cell Disease Implementation Consortium (SCDIC) sites. In multivariate models, PROs were significantly associated with one another. Pain impact was associated with age, education, employment, time since last pain attack, hydroxyurea use, opioid use, sleep impact, social functioning, and cognitive function (F = 88.74, P < .0001). Sleep impact was associated with household income, opioid use, pain impact, social functioning, depressive symptoms, and tiredness (F = 101.40, P < .0001). Social functioning was associated with employment, pain attacks in the past year, autoimmune/inflammatory comorbidities, pain impact, sleep impact, depressive symptoms, tiredness, and cognitive function (F = 121.73, P < .0001). Depressive symptoms were associated with sex, sleep impact, social functioning, tiredness, and cognitive function (F = 239.51, P < .0001). Tiredness was associated with sex, education, sleep impact, social functioning, depressive symptoms, and cognitive function (F = 129.13, P < .0001). These findings reflect the baseline PRO assessments among SCDIC registry participants. Further research is needed to better understand these outcomes and new targets for interventions to improve quality of life and function in people with SCD.

Importance: Sickle cell disease (SCD) is the most common inherited red blood cell disorder in the United States, and previous studies have shown that individuals with SCD are affected by multiple health disparities, including stigmatization, inequities in funding, and worse health outcomes, which may preclude their ability to access quality health care. This needs assessment was performed as part of the Sickle Cell Disease Implementation Consortium (SCDIC) to assess barriers to care that may be faced by individuals with SCD. Objective: To assess the SCD-related medical care experience of adolescents and adults with SCD. Design, Setting, and Participants: This one-time survey study evaluated pain interference, quality of health care, and self-efficacy of 440 adults and adolescents (aged 15 to 50 years) with SCD of all genotypes and assessed how these variables were associated with their perceptions of outpatient and emergency department (ED) care. The surveys were administered once during office visits by trained study coordinators at 7 of 8 SCDIC sites in 2018. Results: The SCDIC sites did not report the number of individuals approached to participate in this study; thus, a response rate could not be calculated. In addition, respondents were not required to answer every question in the survey; thus, the response rate per question differed for each variable. Of 440 individuals with SCD, participants were primarily female (245 [55.7%]) and African American (428 [97.3%]) individuals, with a mean (SD) age of 27.8 (8.6) years. The majority of participants (306 of 435 [70.3%]) had hemoglobin SS or hemoglobin S ß0-thalassemia. Most respondents (361 of 437 [82.6%]) reported access to nonacute (usual) SCD care, and the majority of respondents (382 of 413 [92.1%]) noted satisfaction with their usual care physician. Of 435 participants, 287 (66.0%) reported requiring an ED visit for acute pain in the previous year. Respondents were less pleased with their ED care than their usual care clinician, with approximately half (146 of 287 [50.9%]) being satisfied with or perceiving having adequate quality care in the ED. Participants also noted that when they experienced severe pain or clinician lack of empathy, this was associated with a negative quality of care. Age group was associated with ED satisfaction, with younger patients (<19 vs 19-30 and 31-50 years) reporting better ED experiences. Conclusions and Relevance: These results suggested that a negative perception of care may be a barrier for patients seeking care. These findings underscore the necessity of implementation studies to improve access to quality care for this population, especially in the acute care setting.

BACKGROUND: Although patients with various types of heritable aortopathy often require distal aortic repair, data are limited regarding the most extensive operations-open thoracoabdominal aortic aneurysm (TAAA) repairs. The objective of this multicenter registry study was to characterize TAAA repairs in a large cohort of patients with different heritable aortic diseases. METHODS: From the 3699 patients enrolled at 8 participating centers in the Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) Registry, we identified 155 open TAAA repairs in 142 unique patients. We examined data related to clinical characteristics, surgical techniques, and outcomes. RESULTS: The primary diagnoses included Marfan syndrome (n = 76; 54%), familial thoracic aortic aneurysm and dissections (n = 31; 22%), and Loeys-Dietz syndrome (n = 10; 7%). Most repairs were performed for aneurysms associated with aortic dissection (n = 110; 71%). The most common repairs involved the entire descending thoracic aorta with distal extension (21% Crawford extent I and 36% extent II). Adjuncts used during repair varied substantially. The operative mortality rate was 1.3%. Other complications included paraplegia (4%), acute renal failure (5%), and vocal cord paralysis (21%). Reoperation after TAAA repair was required in a subset of cases for early bleeding (n = 15; 10%) and late repair failure (n = 7; 5%). CONCLUSIONS: Open TAAA repairs are necessary in a variety of heritable aortic diseases. These patients often require extensive surgical repair, and a variety of adjunctive techniques are utilized. The risk of repair failure and the need for reoperation in a subset of patients support the need for vigilant long-term surveillance after repair.

Importance: Uterosacral ligament suspension (ULS) and sacrospinous ligament fixation (SSLF) are commonly performed pelvic organ prolapse procedures despite a lack of long-term efficacy data. Objective: To compare outcomes in women randomized to (1) ULS or SSLF and (2) usual care or perioperative behavioral therapy and pelvic floor muscle training (BPMT) for vaginal apical prolapse. Design, Setting, and Participants: This 2 × 2 factorial randomized clinical trial was conducted at 9 US medical centers. Eligible participants who completed the Operations and Pelvic Muscle Training in the Management of Apical Support Loss Trial enrolled between January 2008 and March 2011 and were followed up 5 years after their index surgery from April 2011 through June 2016. Interventions: Two randomizations: (1) BPMT (n = 186) or usual care (n = 188) and (2) surgical intervention (ULS: n = 188 or SSLF: n = 186). Main Outcomes and Measures: The primary surgical outcome was time to surgical failure. Surgical failure was defined as (1) apical descent greater than one-third of total vaginal length or anterior or posterior vaginal wall beyond the hymen or retreatment for prolapse (anatomic failure), or (2) bothersome bulge symptoms. The primary behavioral outcomes were time to anatomic failure and Pelvic Organ Prolapse Distress Inventory scores (range, 0-300). Results: The original study randomized 374 patients, of whom 309 were eligible for this extended trial. For this study, 285 enrolled (mean age, 57.2 years), of whom 244 (86%) completed the extended trial. By year 5, the estimated surgical failure rate was 61.5% in the ULS group and 70.3% in the SSLF group (adjusted difference, -8.8% [95% CI, -24.2 to 6.6]). The estimated anatomic failure rate was 45.6% in the BPMT group and 47.2% in the usual care group (adjusted difference, -1.6% [95% CI, -21.2 to 17.9]). Improvements in Pelvic Organ Prolapse Distress Inventory scores were -59.4 in the BPMT group and -61.8 in the usual care group (adjusted mean difference, 2.4 [95% CI, -13.7 to 18.4]). Conclusions and Relevance: Among women who had undergone vaginal surgery for apical pelvic organ vaginal prolapse, there was no significant difference between ULS and SSLF in rates of surgical failure and no significant difference between perioperative behavioral muscle training and usual care on rates of anatomic success and symptom scores at 5 years. Compared with outcomes at 2 years, rates of surgical failure increased during the follow-up period, although prolapse symptom scores remained improved. Trial Registration: clinicaltrials.gov Identifier: NCT01166373.

This study analyzed the impact of sex, hemodynamic profile, and valve fusion pattern on aortopathy associated with bicuspid aortic valve (BAV). The National Heart Lung and Blood Institute-sponsored National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) provided comprehensive information on a large population of well-characterized patients with BAV. Of 969 enrolled patients with BAV, 551 (57%, 77% male) had already undergone valvular and/or aortic surgery. Echocardiographic imaging data were available on 339 unoperated or preoperative participants who formed the basis of this study. BAV function was normal in 45 (14%), with a predominant aortic regurgitation (AR) in 127 (41%) and a predominant aortic stenosis (AS) in 76 (22%). Moderate-severe AR was associated with larger sinus of Valsalva (SOV) diameters compared with normal function and AS (all p <0.01). Moderate-severe AS was associated with a larger ascending aortic (AscAo) diameter compared with normal function (p = 0.003) but not with AR. The SOV diameter was larger in men than in women (3.7 ± 0.7 vs 3.3 ± 0.6 cm, p <0.0001), whereas AscAo diameters were comparable (3.9 ± 0.9 vs 3.7 ± 0.9 cm, p = 0.08). Right-left commissural fusion was associated with a larger SOV diameter (3.7 ± 0.7 vs 3.3 ± 0.6 cm, p <0.0001) compared with a right-noncoronary fusion pattern. Predominant AR was more common in men (45% vs 27%, p = 0.004), whereas AS was more common in women (29% vs 18%, p = 0.04). In conclusion, in the GenTAC Registry, AR was associated with diffuse (annular, SOV, and AscAo) enlargement, whereas moderate-severe AS was only associated with AscAo enlargement. Male sex and right-left cusp pattern of cusp fusion were associated with larger SOV diameters and a greater likelihood of AR, whereas women had a higher prevalence of AS.

BACKGROUND: The risk of aortic complications associated with pregnancy in women with Marfan syndrome (MFS) is not fully understood. METHODS AND RESULTS: MFS women participating in the large National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) were evaluated. Among 184 women with MFS in whom pregnancy information was available, 94 (51%) had a total of 227 pregnancies. Among the women with pregnancies, 10 (10.6%) experienced a pregnancy-related aortic complication (4 type A and 3 type B dissections, 1 coronary artery dissection, and 2 with significant [≥3 mm] aortic growth). Five of 7 aortic dissections, including all 3 type B, and the coronary dissection (75% of all dissections) occurred in the postpartum period. Only 5 of 8 women with pregnancy-associated dissection were aware of their MFS diagnosis. The rate of aortic dissection was higher during the pregnancy and postpartum period (5.4 per 100 person-years vs 0.6 per 100 person-years of nonpregnancy; rate ratio, 8.4 [95% CI=3.9, 18.4]; P<0.0001). CONCLUSIONS: Pregnancy in MFS is associated with an increased risk of aortic dissection, both types A and B, particularly in the immediate postpartum period. Lack of knowledge of underlying MFS diagnosis before aortic dissection is a major contributing factor. These findings underscore the need for early diagnosis, prepregnancy risk counseling, and multidisciplinary peripartum management.

The National Institute of Diabetes and Digestive Disease (NIDDK) Central Data Repository (CDR) is a web-enabled resource available to researchers and the general public. The CDR warehouses clinical data and study documentation from NIDDK funded research, including such landmark studies as The Diabetes Control and Complications Trial (DCCT, 1983-93) and the Epidemiology of Diabetes Interventions and Complications (EDIC, 1994-present) follow-up study which has been ongoing for more than 20 years. The CDR also houses data from over 7 million biospecimens representing 2 million subjects. To help users explore the vast amount of data stored in the NIDDK CDR, we developed a suite of search mechanisms called the public query tools (PQTs). Five individual tools are available to search data from multiple perspectives: study search, basic search, ontology search, variable summary and sample by condition. PQT enables users to search for information across studies. Users can search for data such as number of subjects, types of biospecimens and disease outcome variables without prior knowledge of the individual studies. This suite of tools will increase the use and maximize the value of the NIDDK data and biospecimen repositories as important resources for the research community.

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repository makes data and biospecimens from NIDDK-funded research available to the broader scientific community. It thereby facilitates: the testing of new hypotheses without new data or biospecimen collection; pooling data across several studies to increase statistical power; and informative genetic analyses using the Repository's well-curated phenotypic data. This article describes the initial database plan for the Repository and its revision using a simpler model. Among the lessons learned were the trade-offs between the complexity of a database design and the costs in time and money of implementation; the importance of integrating consent documents into the basic design; the crucial need for linkage files that associate biospecimen IDs with the masked subject IDs used in deposited data sets; and the importance of standardized procedures to test the integrity data sets prior to distribution. The Repository is currently tracking 111 ongoing NIDDK-funded studies many of which include genotype data, and it houses over 5 million biospecimens of more than 25 types including serum, plasma, stool, urine, DNA, red blood cells, buffy coat and tissue. Repository resources have supported a range of biochemical, clinical, statistical and genetic research (188 external requests for clinical data and 31 for biospecimens have been approved or are pending). Genetic research has included GWAS, validation studies, development of methods to improve statistical power of GWAS and testing of new statistical methods for genetic research. We anticipate that the future impact of the Repository's resources on biomedical research will be enhanced by (i) cross-listing of Repository biospecimens in additional searchable databases and biobank catalogs; (ii) ongoing deployment of new applications for querying the contents of the Repository; and (iii) increased harmonization of procedures, data collection strategies, questionnaires etc. across both research studies and within the vocabularies used by different repositories.

BACKGROUND: Limited data are available on whether sampling from the penile shaft or urethra increases detection of penile HPV infection in men beyond that found in the glans and coronal sulcus. METHODS: Within a randomized clinical trial, a validation study of penile sampling was conducted in Kisumu, Kenya. Young men (18-24 years) were invited to provide penile exfoliated cells using prewetted Dacron swabs to determine the best site for HPV detection. beta-Globin gene PCR and HPV DNA type GP5+/6+ PCR status were ascertained from 3 anatomical sites. RESULTS: A total of 98 young HIV-seronegative, uncircumcised men participated. Penile HPV prevalence varied by anatomical site: 50% in penile exfoliated cells from the glans, coronal sulcus, and inner foreskin tissue; 43% in the shaft and external foreskin tissue; and 18% in the urethra (P <0.0001). For each anatomical site, over 87% of samples were beta-globin positive. Beyond that found in the glans/coronal sulcus, urethral sampling resulted in no increase in HPV positivity and shaft sampling resulted in an additional 7.3% of overall HPV positivity. The prevalence of high-risk HPV positivity varied by anatomical site: 39% in glans/coronal sulcus, 31% in shaft, and 13% in the urethra (P <0.0001). HPV 16 was the most common type identified. DISCUSSION: Penile HPV prevalence was approximately 50% among young men in Kisumu, Kenya. Urethral sampling for HPV detection in men added no sensitivity for HPV detection over that found from sampling the glans/coronal sulcus and penile shaft. These data will help inform studies on HPV transmission dynamics, and on the efficacy of HPV prophylactic vaccines on penile HPV carriage in men.

CONTEXT: Extracts of Hypericum perforatum (St John's wort) are widely used for the treatment of depression of varying severity. Their efficacy in major depressive disorder, however, has not been conclusively demonstrated. OBJECTIVE: To test the efficacy and safety of a well-characterized H perforatum extract (LI-160) in major depressive disorder. DESIGN AND SETTING: Double-blind, randomized, placebo-controlled trial conducted in 12 academic and community psychiatric research clinics in the United States. PARTICIPANTS: Adult outpatients (n = 340) recruited between December 1998 and June 2000 with major depression and a baseline total score on the Hamilton Depression Scale (HAM-D) of at least 20. INTERVENTIONS: Patients were randomly assigned to receive H perforatum, placebo, or sertraline (as an active comparator) for 8 weeks. Based on clinical response, the daily dose of H perforatum could range from 900 to 1500 mg and that of sertraline from 50 to 100 mg. Responders at week 8 could continue blinded treatment for another 18 weeks. MAIN OUTCOME MEASURES: Change in the HAM-D total score from baseline to 8 weeks; rates of full response, determined by the HAM-D and Clinical Global Impressions (CGI) scores. RESULTS: On the 2 primary outcome measures, neither sertraline nor H perforatum was significantly different from placebo. The random regression parameter estimate for mean (SE) change in HAM-D total score from baseline to week 8 (with a greater decline indicating more improvement) was -9.20 (0.67) (95% confidence interval [CI], -10.51 to -7.89) for placebo vs -8.68 (0.68) (95% CI, -10.01 to -7.35) for H perforatum (P =.59) and -10.53 (0.72) (95% CI, -11.94 to -9.12) for sertraline (P =.18). Full response occurred in 31.9% of the placebo-treated patients vs 23.9% of the H perforatum-treated patients (P =.21) and 24.8% of sertraline-treated patients (P =.26). Sertraline was better than placebo on the CGI improvement scale (P =.02), which was a secondary measure in this study. Adverse-effect profiles for H perforatum and sertraline differed relative to placebo. CONCLUSION: This study fails to support the efficacy of H perforatum in moderately severe major depression. The result may be due to low assay sensitivity of the trial, but the complete absence of trends suggestive of efficacy for H perforatum is noteworthy.
