Recurrent Acute Chest Syndrome in Pediatric Sickle Cell Disease: Clinical Features and Risk Factors.

Acute chest syndrome (ACS) is a common and serious lung complication in sickle cell disease. A retrospective medical chart review was performed over a 6-year period in all pediatric ACS patients to investigate whether factors during the initial hospitalization were associated with recurrent ACS episodes. There were 386 episodes of ACS: 149 had only 1 episode of ACS, and 76 had >1 episode of ACS; 172 (76.4%) had hemoglobin SS, and 39 (17.3%) had hemoglobin SC. The most common presenting features were fever (83%), pain (70%), and cough (61%), which changed with the number of ACS episodes. Children <4 years old were at greatest risk of recurrent ACS (P=0.018). In addition, history of asthma (adjusted incident rate ratio [IRR]=1.52; 95% confidence interval [CI], 1.22-1.98; P<0.0001), shortness of breath (IRR, 1.29; 95% CI, 1.02-1.62; P=0.033), and length of hospital stay (IRR, 1.04; 95% CI, 1.01-1.08; P=0.017) were significantly associated with prospective ACS events. Multiple episodes of ACS are common in sickle cell disease, and certain risk factors during the initial hospitalization are associated with recurrent ACS.

Fetal alcohol spectrum disorders and assessment of maxillary and mandibular arc measurements.

Fetal alcohol spectrum disorders (FASD) comprise a range of physical differences and neurologic deficits from prenatal alcohol exposure. Previous studies suggest that relative maxillary growth deficiency can accompany FASD. Using the Fetal Alcohol Syndrome Epidemiologic Research (FASER) database, we investigated how maxillary and mandibular arcs and the ratio between them differ between FASD and non-FASD individuals. First, we established normative values for maxillary and mandibular arcs and maxillary-to-mandibular arc ratio. In our control group (545 males, 436 females), mean maxillary and mandibular arcs for males/females were 24.98/24.52 cm and 25.91/25.35 cm, respectively. The ratio was 0.9643 and 0.9676 for males and females, respectively. We then evaluated the effect of microcephaly, short stature, and low weight (<10th centile), individually on arcs in controls. Generally, arcs were reduced significantly but the ratio did not differ. We compared our controls to 138 male and 135 female FASD cases. We noted a significant difference in arcs in male and female groups, but not the ratio. We compared non-FAS controls with reduced growth parameters to similar cases with FASD. We did not find a significant difference in arc or ratio measurements. Therefore, we conclude the effect of prenatal alcohol exposure on maxillary and mandibular arc measurements is primarily on overall facial growth and less on asymmetric growth of the maxilla relative to the mandible, at least using this technique. © 2016 Wiley Periodicals, Inc.

The impact of neighborhood on physical activity in the Jackson Heart Study.

Physical inactivity is an independent risk factor for many diseases. Most research has focused on individual-level factors for physical activity (PA), but evidence suggests that neighborhood is also important. We examined baseline data collected between 2000 and 2004 from 5236 participants in the Jackson Heart Study to determine the effects of neighborhood on 2 types of PA: Active Living (AL), and Sports and Exercise (Sport) in an all-African American cohort. Participants were georeferenced and data from individual baseline questionnaires and US Census were analyzed using descriptive, bivariate, and multilevel models. In both types of PA, neighborhood factors had an independent and additive effect on AL and Sport. Living in an urban (p=0.003) or neighborhood with a higher percentage of residents with less than a high school education (p<0.001) was inversely associated with AL. There was an inverse interaction effect between individual and lower neighborhood education (p=0.01), as well as between age and urban neighborhoods (p=0.02) on AL. Individual level education (OR=1.30) and per capita income (OR=1.07) increased the odds of moderate-to-high sports. Future studies should focus on what contextual aspects of urban or less educated neighborhoods are influential in determining PA, as well as longitudinal multilevel analyses of neighborhood effects on PA.

Resident fatigue in otolaryngology residents: a Web based survey.

IMPORTANCE: Resident fatigue has become a point of emphasis in medical education and its effects on otolaryngology residents and their patients require further study. OBJECTIVE: The purpose of our study was to evaluate the prevalence and nature of fatigue in otolaryngology residents, evaluate various quality of life measures, and investigate associations of increased fatigue with resident safety. STUDY DESIGN: Anonymous survey. SETTING: Internet based. PARTICIPANTS: United States allopathic otolaryngology residents. INTERVENTION: None. MAIN OUTCOME(S) AND MEASURES: The survey topics included demographics, residency structure, sleep habits and perceived stress. Responses were correlated with a concurrent Epworth Sleep Scale questionnaire to evaluate effects of fatigue on resident training and quality of life. RESULTS: 190 residents responded to the survey with 178 completing the Epworth Sleep Scale questionnaire. Results revealed a mean Epworth Sleep Scale score of 9.9±5.1 with a median of 10.0 indicating a significant number of otolaryngology residents are excessively sleepy. Statistically significant correlations between Epworth Sleep Scale and sex, region, hours of sleep, and work hours were found. Residents taking in-house call had significantly fewer hours of sleep compared to home call (p=0.01). Residents on "head and neck" (typically consisting of a large proportion of head and neck oncologic surgery) rotations tended to have higher Epworth Sleep Scale and had significantly fewer hours of sleep (p=.003) and greater work hours (p<.001). Additionally, residents who reported no needle stick type incidents or near motor vehicle accidents had significantly lower mean Epworth Sleep Scale scores. Only 37.6% of respondents approve of the most recent Accreditation Council for Graduate Medical Education work hour restrictions and 14% reported averaging greater than 80hours of work/week. CONCLUSION AND RELEVANCE: A substantial number of otolaryngology residents are excessively sleepy. Our data suggest that the effects of fatigue play a role in resident well-being and resident safety.

Is It a Trust Issue? Factors That Influence Trust for Persons Living With HIV/AIDS.

Trust in one's health care provider, trust in the health care system in general, and even trust in one's community affects engagement in HIV-related health care. This article examines the issue of trust among a random sample of HIV-infected individuals residing in Mississippi, an area hard-hit by the HIV/AIDS epidemic. Five constructs based on survey responses from these individuals were developed: (1) trust in one's provider to offer the best possible medical care, (2) trust in one's provider to protect patient privacy, (3) willingness to disclose HIV status to one's provider, (4) trust in the health care system, and (5) trust in one's community. Findings suggest that interventions to improve trust in providers to deliver the highest quality of care should be targeted to young people, African Americans, and the more highly educated. Interventions to increase trust in providers to protect privacy should focus on creating and strengthening social support groups or networks that build relationships and foster trust. Interventions aimed to increase community trust also should be targeted to young people. This information is useful to researchers, policy makers, health care providers, and organizations interested in prioritizing interventions and strategies that have the greatest potential to reduce health disparities in HIV diagnosis and treatment in the Deep South.

The IFNγ-PKR pathway in the prefrontal cortex reactions to chronic excessive alcohol use.

BACKGROUND: Brain cell death is a major pathological consequence of alcohol neurotoxicity. However, the molecular cascades in alcohol-induced brain tissue injury are unclear. METHODS: Using Western blot and double immunofluorescence, we examined the expression of interferon (IFN)-induced protein kinase R (PKR), phosphorylated-PKR (p-PKR), and IFN gamma (IFNγ) in the prefrontal cortex (PFC) of postmortem brains from subjects with alcohol use disorders (AUD). RESULTS: The protein levels of PKR, p-PKR, and IFNγ were significantly increased in subjects with AUD compared with control subjects without AUD, and a younger age of onset of AUD was significantly correlated with higher protein levels of p-PKR. In addition, elevated PKR- and p-PKR-IR were observed in both neurons and astrocytes in the PFC of subjects with AUD compared to subjects without AUD. CONCLUSIONS: The activation of the IFNγ-PKR pathway in PFC of humans is associated with chronic excessive ethanol use with an age of onset dependent manner, and activation of this pathway may play a pivotal role in AUD-related brain tissue injury. This study provides insight into neurodegenerative key factors related to AUD and identifies potential targets for the treatment of alcohol-induced neurotoxicity.

Gene-environment interaction between SCN5A-1103Y and hypokalemia influences QT interval prolongation in African Americans: the Jackson Heart Study.

BACKGROUND: African-American ancestry, hypokalemia, and QT interval prolongation on the electrocardiogram are all risk factors for sudden cardiac death (SCD), but their interactions remain to be characterized. SCN5A-1103Y is a common missense variant, of African ancestry, of the cardiac sodium channel gene. SCN5A-1103Y is known to interact with QT-prolonging factors to promote ventricular arrhythmias in persons at high risk for SCD, but its clinical impact in the general African-American population has not been established. METHODS: We genotyped SCN5A-S1103Y in 4,476 participants of the Jackson Heart Study, a population-based cohort of African Americans. We investigated the effect of SCN5A-1103Y, including interaction with hypokalemia, on QT interval prolongation, a widely-used indicator of prolonged myocardial repolarization and predisposition to SCD. We then evaluated the two sub-components of the QT interval: QRS duration and JT interval. RESULTS: The carrier frequency for SCN5A-1103Y was 15.4%. SCN5A-1103Y was associated with QT interval prolongation (2.7 milliseconds; P < .001) and potentiated the effect of hypokalemia on QT interval prolongation (14.6 milliseconds; P = .02). SCN5A-1103Y had opposing effects on the two sub-components of the QT interval, with shortening of QRS duration (-1.5 milliseconds; P = .001) and prolongation of the JT interval (3.4 milliseconds; P < .001). Hypokalemia was associated with diuretic use (78%; P < .001). CONCLUSIONS: SCN5A-1103Y potentiates the effect of hypokalemia on prolonging myocardial repolarization in the general African-American population. These findings have clinical implications for modification of QT prolonging factors, such as hypokalemia, in the 15% of African Americans who are carriers of SCN5A-1103Y.

The expression of KLF11 (TIEG2), a monoamine oxidase B transcriptional activator in the prefrontal cortex of human alcohol dependence.

BACKGROUND: The biochemical pathways underlying alcohol abuse and dependence are not well understood, although brain cell loss and neurotoxicity have been reported in subjects with alcohol dependence. Monoamine oxidase B (MAO B; an enzyme that catabolizes neurotransmitters such as dopamine) is consistently increased in this psychiatric illness. MAO B has been implicated in the pathogenesis of alcohol dependence and alcohol-induced brain neurotoxicity. Recently, the cell growth inhibitor protein, Kruppel-like factor 11 (KLF11), has been reported to be an MAO transcriptional activator. KLF11 is also known as TIEG2 (transforming growth factor-beta-inducible early gene 2) and mediates apoptotic cell death. This study investigates the protein expression of KLF11 and its relationship with MAO B using human postmortem prefrontal cortex from subjects with alcohol dependence. METHODS: Twelve subjects with alcohol dependence and the respective psychiatrically normal control subjects were investigated. Expression of KLF11 and MAO B proteins in the prefrontal cortex was measured by Western blot analysis. Correlation studies involving KLF11 and MAO B protein expression were performed. Localization of KLF11 in the human prefrontal cortex was also determined by immunohistochemistry. RESULTS: Levels of KLF11 protein were significantly increased by 44% (p < 0.03) in the postmortem prefrontal cortex of subjects with alcohol dependence as compared to age- and gender-matched, psychiatrically normal control subjects. Furthermore, KLF11 levels were significantly and positively correlated with both the increased MAO B protein levels and blood alcohol content in alcohol-dependent subjects. In addition, KLF11 protein expression was visualized in both neuronal and glial cells. CONCLUSIONS: This novel study shows the important role of KLF11, an MAO transcriptional activator, in human alcohol dependence. It further supports that the KLF11-MAO B cell death cascade may contribute to chronic alcohol-induced brain damage. This argues a case for KLF11-MAO B inhibition as a novel therapeutic strategy that may impact this highly prevalent illness.

Using a mandatory reporting database to recruit persons living with HIV/AIDS to study access to care in Mississippi.

Using funds provided by the Ryan White Care Act, we conducted a statewide needs assessment of persons living with HIV/AIDS (PLWHA) in Mississippi as required by provisions of the Act. Most published research addressing access to care for PLWHA is based on convenience samples of persons already accessing care in specified clinic locations. For this study of a single state with a well-established mandatory reporting system, we conducted a cross-sectional study interviewing a random sample of PLWHA across the state of Mississippi. The Mississippi State Department of Health has maintained the Mississippi HIV/AIDS Reporting System since its inception in 1980. The database tracks all reported cases of HIV+ cases and includes name, age, last-known address, and other contact information. The sample was selected from a frame of all recorded PLWHA in Mississippi at that time, regardless of their association with care facilities. The purpose of this article is to describe the design and methodology of this study, difficulties encountered in locating this hard-to-reach population, multimethod recruiting strategies and outcomes, and lessons learned. Locating participants using a truly random sample from a mandatory reporting database was resource intensive. However, data collected as a result of these efforts have provided invaluable information on a number of topics important to PLWHA.

Associations between factors affecting access to care and health-related quality of life: results of a statewide HIV/AIDS cross-sectional study.

The objective of this cross-sectional study was to describe the relationship between access to care and health-related quality of life (HRQOL) for persons living with HIV/AIDS (PLWHA) in Mississippi by administering a statewide survey. A random probability sample of PLWHA was derived from the Mississippi State Department of Health's communicable disease tracking system. Interviews were conducted with 220 PLWHA to collect data on access to care, demographic and social characteristics, and HRQOL. Overall, most participants had access to care and reasonable HRQOL. Multivariate and univariate analyses were performed to measure associations between access to care and HRQOL. Univariate analyses showed that age, income, social networks, severity of disease, having been prescribed medications, and having experienced problems accessing care to be significantly associated with HRQOL scales. Multivariate analysis of variance models further demonstrated low-income level, having experienced problems accessing care, and having been prescribed antiretroviral medications to be significantly associated with HRQOL. Reducing barriers is a major factor in improving quality of life. This study provides needed insight into the relationship between access to care and HRQOL among PLWHA in Mississippi, which could be valuable to public health planners to help them better understand how to make the greatest impact on HRQOL.

Determining unmet, adequately met, and overly met needs for health care and services for persons living with HIV/AIDS in Mississippi.

A statewide needs assessment of persons living with HIV/AIDS (PLWHA) was conducted to determine what is known about access to care, utilization of services, and perceived barriers to receiving care and services. Our objective was to determine which needs were being met or unmet among PLWHA in Mississippi to provide a better understanding of how effectively to allocate funding to provide for the needs of that group. In this cross-sectional study, a true random sample of PLWHA in Mississippi was interviewed in 2005-2006. Questions were asked to identify opinions about respondents' experiences with 23 health care services and 30 public or private assistance services. The kappa statistic was used to measure agreement between level of services needed and level of services provided. Services with the lowest kappa scores revealed which services were being either mostly unmet, or even overly met. Greatest service needs were HIV viral load test, Pap smear, CD4/T-cell count test, and medication for HIV/AIDS, which were reasonably well met. The most significantly unmet needs were dental care and dental exams, eye care and eye exams, help paying for housing, subsidized housing assistance, mental health therapy or counseling, access to emotional support groups, and job placement or employment. Overly met services included medical care at a physician's office or clinic and free condoms. This study identified needs perceived to be significantly unmet by PLWHA, as well as areas that were perceived to be adequately or overly met. This information may be used to target areas with the greatest impact for improvement and provide insight into how to effectively allocate health care resources and public/private assistance.

Factors affecting wound leakage in 23-gauge sutureless pars plana vitrectomy.

PURPOSE: To evaluate risk factors for sclerotomy leakage in 23-gauge sutureless pars plana vitrectomy in 219 patients. METHODS: Nested case-control study involving 48 patients with wound leaks (visible on-table sclerotomy leakage requiring sutures) and 171 control subjects without wound leaks. Patients received either a conventional sclerotomy incision at 45°, which was then changed to 90° midincision, or an extremely oblique sclerotomy incision (OSI) at 10°, which was then changed to 30° midincision. Risk factors studied included age, gender, laterality, surgical duration, sclerotomy incision (OSI vs. conventional sclerotomy incision), preoperative diagnosis (macular vs. nonmacular), history of vitrectomy, and primary surgeon (attending vs. supervised resident). RESULTS: Multivariate logistic regression analysis found significant (P ≤ 0.05) protective factors for wound leakage including OSI, macular preoperative diagnosis, no previous vitrectomy, and female gender. Surgical duration at least 45 minutes was considered a borderline risk factor. CONCLUSION: Using an extremely OSI versus a conventional sclerotomy incision reduces the incidence of wound leakage postoperatively because of its self-sealing effect. Other factors that contribute to wound leakage, such as increased surgical duration and nonmacular diagnosis, may be indirect measurements of extensive trocar rotation, causing wound leakage despite the use of an OSI.

Treatment and outcomes for pediatric head injuries in Mississippi.

OBJECT: This report summarizes the treatments and outcomes of a large series of patients with pediatric head injuries (PHIs), who were admitted to a tertiary pediatric trauma center at the University of Mississippi Medical Center from January 1, 2003 through December 31, 2006. METHODS: Data were retrieved from the Department of Neurosurgery's Brain Trauma Registry (BTR) on patients who are ≤16 years old. Data include Glasgow Coma Scale (GCS) and injury severity scores (ISS) on admission and Glasgow Outcome Scale (GOS) scores at 6 months follow-up. RESULTS: The BTR registered 554 patients with accidental and nonaccidental PHIs. Follow-up was complete in 98.2%. Aggressive first-tier management with ventricular drainage was used to lower intracranial pressure. Vasopressors were used only to correct hypotension. Second-tier therapies were used infrequently. Craniectomies (14 patients) were associated with good outcomes (GOS 4-5) in nine patients; hypothermia (six patients) and barbiturate (four patients) therapies were ineffective. All 439 patients with ISS <25 showed good outcomes. Fifteen of 16 patients with GCS >8 and ISS ≥25 had good outcomes. In 134 patients with severe PHIs (GCS ≤8), all 45 with ISS <25 and 46 with ISS ≥25 showed good outcomes. Forty-three patients with GCS ≤8 and ISS ≥25 had poor outcomes. Of these patients, 38 died; 22 died within 3 days of admission. CONCLUSIONS: This study indicated that poor outcomes occurred only in PHIs with severe generalized trauma. While 28.4% of patients with GSC ≤8 died, more than half of these sustained nonsurvivable injuries. Aggressive medical management with ventricular drainage was the mainstay of therapy.

Using small-area estimation method to calculate county-level prevalence of obesity in Mississippi, 2007-2009.

INTRODUCTION: Obesity is one of Mississippi's pressing public health problems. Since 2005, the state has ranked first in the nation in adult obesity prevalence. For authorities to take targeted action against the obesity epidemic, counties, regions, and subpopulations that are most affected by obesity need to be identified. The objective of this study was to assess the scope, socioeconomic and geographic characteristics, and temporal trends of the obesity epidemic in Mississippi. METHODS: Using 2007-2009 Mississippi Behavioral Risk Factor Surveillance System data and auxiliary data, we applied a small-area estimation method to estimate county-level obesity prevalence in 2007 through 2009, to assess the association between obesity and socioeconomic factors and to evaluate temporal trends. We determined geographic patterns by mapping obesity prevalence. We appraised the precision of estimates by the width of 95% confidence intervals, and we validated our small-area estimates by comparing them with direct estimates. RESULTS: In 2009, the county prevalence of obesity ranged from 30.5% to 44.2%. Counties with the highest prevalence of obesity were in the Delta region and along the Mississippi River. The obesity prevalence increased from 2007 through 2009. Age, sex, race, education, and employment status were associated with obesity. CONCLUSION: The 2009 obesity prevalence in all Mississippi counties was substantially higher than the national average and differed by geography and race. Although urgent intervention measures are needed in the entire state, policies and programs giving higher priority to higher-risk areas and subpopulations identified by this study may be better strategies.

HELLP syndrome with and without eclampsia.

We assessed pregnancy outcomes for patients with HELLP syndrome (hemolysis; elevated liver enzymes; low platelet count) with and without concurrent eclampsia. We performed a retrospective investigation of data spanning three decades of patients with class 1 or 2 HELLP syndrome with concurrent eclampsia (HELLP + E) and patients with HELLP syndrome without eclampsia. Data were analyzed by appropriate tests for continuous or categorical outcomes with differences considered significant if P < 0.05. During 1981 to 1996 and 2000 to 2006, there were 693 patients with class 1 or 2 HELLP syndrome; altogether, 70 patients had HELLP + E. The only demographic difference was greater nulliparity in HELLP + E patients. Otherwise, inconsistent and clinically insignificant differences were observed between groups. Despite the relatively large size of the study groups, we were unable to detect a significant worsening of maternal or perinatal outcome in HELLP + E patients compared with HELLP patients. In our experience, eclampsia does not appear to contribute a significant adverse impact upon the course or outcome of HELLP syndrome pregnancies.

Comparison of the Vineland Adaptive Behavior Scales, Second Edition, and the Bayley Scales of Infant and Toddler Development, Third Edition.

The Vineland Adaptive Behavior Scales, Second Edition (Vineland-II), and Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) were administered to 65 children between the ages of 12 and 42 months referred for developmental delays. Standard scores and age equivalents were compared across instruments. Analyses showed no statistical difference between Vineland-II ABC standard scores and cognitive levels obtained from the Bayley-III. However, Vineland-II Communication and Motor domain standard scores were significantly higher than corresponding scores on the Bayley-III. In addition, age equivalent scores were significantly higher on the Vineland-II for the fine motor subdomain. Implications for early intervention are discussed.

Current tobacco use trends among Mississippi public high school students: 1993-2009.

This study investigates trends in tobacco use based on gender, race, and grade level among Mississippi public high school students during 1993-2009. Data were obtained by combining eight weighted Mississippi Youth Risk Behavior Surveys (YRBS). Current tobacco use (cigarette, smokeless, and cigar) was selected for investigation. During 1993-2009, the prevalence of current cigarette and cigar use among Mississippi public high school students showed a significant linear decrease (p < 0.0001). A quadratic trend was also detected for current cigarette use (p = 0.0038) indicating that it increased during 1993-1995 and then decreased over the remaining period of the study. Neither linear nor quadratic trends were observed for current smokeless tobacco use. Male students were more likely to be current tobacco users. White students were more likely to use cigarettes and smokeless tobacco. Programs that target male and white students on certain products such as smokeless tobacco are needed to further decrease overall tobacco use in the state.

Transcriptional expression of serotonergic regulators in laser-captured microdissected dorsal raphe neurons of subjects with major depressive disorder: sex-specific differences.

The relationship between serotonin (5-HT) and major depressive disorder (MDD) has been extensively studied but certain aspects are still ambiguous. Given the evidence that 5-HT neurotransmission is reduced in depressed subjects, it is possible that one or more of the 5-HT regulators may be altered in the dorsal raphe nucleus (DR) of depressed subjects. Candidates that regulate 5-HT synthesis and neuronal activity of 5-HT neurons include intrinsic regulators such as tryptophan hydroxylase 2, 5-HT autoreceptors, 5-HT transporter and transcription factors, as well as afferent regulators such as estrogen and brain-derived neurotrophic factor. The present study was designed to quantify mRNA concentrations of the above 5-HT regulators in an isolated population of 5-HT-containing DR neurons of MDD subjects and gender-matched psychiatrically normal control subjects. We found that mRNA concentrations of the 5-HT1D receptor and the transcription factors, NUDR and REST, were significantly increased in DR-captured neurons of female MDD subjects compared to female control subjects. No significant differences were found for the transcripts in male MDD subjects compared to male controls. This study reveals sex-specific alterations in gene expression of the pre-synaptic 5-HT1D autoreceptors and 5-HT-related transcription factors, NUDR and REST, in DR neurons of women with MDD.

Decreased expression of Freud-1/CC2D1A, a transcriptional repressor of the 5-HT1A receptor, in the prefrontal cortex of subjects with major depression.

Serotonin1A (5-HT(1A)) receptors are reported altered in the brain of subjects with major depressive disorder (MDD). Recent studies have identified transcriptional regulators of the 5-HT(1A) receptor and have documented gender-specific alterations in 5-HT(1A) transcription factor and 5-HT(1A) receptors in female MDD subjects. The 5' repressor element under dual repression binding protein-1 (Freud-1) is a calcium-regulated repressor that negatively regulates the 5-HT(1A) receptor gene. This study documented the cellular expression of Freud-1 in the human prefrontal cortex (PFC) and quantified Freud-1 protein in the PFC of MDD and control subjects as well as in the PFC of rhesus monkeys chronically treated with fluoxetine. Freud-1 immunoreactivity was present in neurons and glia and was co-localized with 5-HT(1A) receptors. Freud-1 protein level was significantly decreased in the PFC of male MDD subjects (37%, p=0.02) relative to gender-matched control subjects. Freud-1 protein was also reduced in the PFC of female MDD subjects (36%, p=0.18) but was not statistically significant. When the data was combined across genders and analysed by age, the decrease in Freud-1 protein level was greater in the younger MDD subjects (48%, p=0.01) relative to age-matched controls as opposed to older depressed subjects. Similarly, 5-HT(1A) receptor protein was significantly reduced in the PFC of the younger MDD subjects (48%, p=0.01) relative to age-matched controls. Adult male rhesus monkeys administered fluoxetine daily for 39 wk revealed no significant change in cortical Freud-1 or 5-HT(1A) receptor proteins compared to vehicle-treated control monkeys. Reduced protein expression of Freud-1 in MDD subjects may reflect dysregulation of this transcription factor, which may contribute to the altered regulation of 5-HT(1A) receptors observed in subjects with MDD. These data may also suggest that reductions in Freud-1 protein expression in the PFC may be associated with early onset of MDD.

Incidence of vaginal cuff dehiscence after open or laparoscopic hysterectomy: a case report.

BACKGROUND: The incidence of vaginal incision dehiscence after total hysterectomy has been reported to be higher with laparoscopic than with open surgery, but the data are limited. This report documents a case and reviews the literature in order to further estimate the differences in incidence by route of hysterectomy. CASE: A 45-year-old woman underwent successful vaginal repair of postcoital cuff dehiscence with small bowel evisceration 67 days after total laparoscopic hysterectomy and bilateral salpingo-oophorectomy for menometrorhagia. CONCLUSION: Seven observational studies were identified. The comparison of total laparoscopic to robotic hysterectomy was not statistically significant, nor was the comparison of total abdominal to vaginal hysterectomy. However, the incidence of dehiscence for laparoscopic procedures was statistically greater than the incidence for open surgery (p value <0.001).
