Birth prevalence of congenital heart disease among newborns in a tertiary hospital in Benin City, Nigeria.

BACKGROUND: Congenital heart disease (CHD) is an important cause of childhood morbidity. The birth prevalence and distribution of CHD among neonates in a tertiary hospital in Nigeria was determined. METHODS: This descriptive, cross-sectional study involved consecutive neonates in the neonatal and postnatal wards of the hospital. Bedside echocardiography was conducted on all neonates. Data entry and analysis was done with IBM-SPSS version 20.0. RESULTS: A total of 2 849 neonates were recruited, consisting of 1 482 (52.0%) males. Forty-one neonates had CHD, giving a birth prevalence of 14.4/1 000 live births. Of the 41 with CHD, 21 (51.2%) were male. Thirty-six (87.8%) neonates had acyanotic CHD, of which the commonest was isolated ventricular septal defect [11 (26.8%)]. Transposition of the great arteries [3 (7.3%)] was the commonest cyanotic CHD. CONCLUSIONS: The birth prevalence of 14.4/1 000 live births in this study is high and buttresses the need for strengthening existing cardiac services in Nigeria.

Novel use of social media to assess and improve coastal flood forecasts and hazard alerts.

Coastal communities and infrastructure need protection from flooding and wave overtopping events. Assessment of hazard prediction methods, used in sea defence design, defence performance inspections and forecasting services, requires observations at the land-sea interface but these are rarely collected. Here we show how a database of hindcast overtopping events, and the conditions that cause them, can be built using qualitative overtopping information obtained from social media. We develop a database for a case study site at Crosby in the Northwest of England, use it to test the standard methods applied in operational flood forecasting services and new defence design, and suggest improvements to these methods. This novel approach will become increasingly important to deliver long-term, cost-effective coastal management solutions as sea-levels rise and coastal populations grow. At sites with limited, or no, monitoring or forecasting services, this approach, especially if combined with citizen science initiatives, could underpin the development of simplified early warning systems.

Examining the role of mother-child interactions and DNA methylation of the oxytocin receptor gene in understanding child controlling attachment behaviors.

This study examined mother-child interactions and DNA methylation of the oxytocin receptor (OXTR) gene in the child, in relation with controlling-attachment behaviors at early preschool age. Maternal interactive behaviors were coded using the Emotional Availability Scales, and child attachment behaviors were assessed with the Separation-Reunion procedure and coded with the Preschool Attachment Rating Scales. DNA methylation data were captured from exon 3 of the OXTR. Results indicated that lower maternal sensitivity was associated with more controlling-caregiving behaviors, and that less maternal structuring was associated with more controlling-punitive behaviors. Hypomethylation of the OXTR gene was associated with greater maternal structuring behaviors, and with more child controlling-caregiving behaviors. The moderating role of the OXTR gene was examined in the association between interactive behaviors and child controlling behaviors, but no interaction effect was found. These results suggest that maternal interactive behaviors and OXTR methylation are independently associated with child controlling attachment.

Sleep quality is associated with vasopressin methylation in pregnant and postpartum women with a history of psychosocial stress.

BACKGROUND: The relationship between disturbed sleep and stress is well-documented. Sleep disorders and stress are highly prevalent during the perinatal period, and both are known to contribute to a number of adverse maternal and foetal outcomes. Arginine vasopressin (AVP) is a hormone and a neuropeptide that is involved in stress response, social bonding and circadian regulation of the sleep-wake cycle. Whether the AVP system is involved in regulation of stress response and sleep quality in the context of the perinatal mental health is currently unknown. The objective of the present study was to assess the relationship between levels of cumulative and ongoing psychosocial risk, levels of disordered sleep and AVP methylation in a community sample of pregnant and postpartum women. METHODS: A sample of 316 participants completed a battery of questionnaires during the second trimester of pregnancy (PN2, 12-14 weeks gestation), third trimester (PN3, 32-34 weeks gestation), and at 7-9 weeks postpartum (PP). Disordered sleep was measured using the Sleep Symptom Checklist at PN2, PN3 and PP; cumulative psychosocial risk was assessed with the Antenatal Risk Questionnaire (ANRQ) at PN2; salivary DNA was collected at the follow-up (FU, 2.9 years postpartum); and % methylation were calculated for AVP and for two of the three AVP receptor genes (AVPR1a and AVPR1b). Women were separated into high (HighPR) and low (LowPR) psychosocial risk groups, based on their scores on the ANRQ. RESULTS: Women in the HighPR group had significantly worse sleep disturbances during PN2 (p < .001) and PN3 (p < .001), but not at PP (p = .146) than women in the LowPR group. In HighPR participants only, methylation of AVP at intron 1 negatively correlated with sleep disturbances at PN2 (rs=-.390, p = .001), PN3 (rs=-.384, p = .002) and at PP (rs= -.269, p = .032). There was no association between sleep disturbances and AVPR1a or AVPR1b methylation, or between sleep disturbances and any of the AVP methylation for the LowPR group. Lastly, cumulative psychosocial stress was a moderator for the relationship between AVP intron 1 methylation and disordered sleep at PN2 (p < .001, adjusted R2 = .105), PN2 (p < .001, adjusted R2 = .088) and PP (p = .003, adjusted R2 = .064). CONCLUSIONS: Our results suggest that cumulative psychosocial stress exacerbates sleep disorders in pregnant women, and that salivary DNA methylation patterns of the AVP gene may be seen as a marker of biological predisposition to stress and sleep reactivity during the perinatal period. Further research is needed to establish causal links between AVP methylation, sleep and stress.

African americans may have to consume more than 12 grams a day of resistant starch to lower their risk for type 2 diabetes.

African Americans have a high prevalence rate of type 2 diabetes mellitus (DM). High-maize 260 (National Starch and Chemical Co., Bridgewater, NJ, USA) resistant starch (RS) is a promising food ingredient to reduce risk factors for type 2 DM. A 14-week, double-blind, crossover design study was conducted with African American male (n = 8) and female (n = 7) subjects at risk for type 2 DM. All subjects consumed bread containing 12 g of added RS or control bread (no added RS) for 6 weeks, separated by a 2-week washout period. There were no significant differences in the subjects' fasting plasma glucose levels due to the consumption of the RS bread versus the control bread. Fructosamine levels were significantly lower after consumption of both RS and control bread than at baseline. However, we found no significant difference in fructosamine levels due to treatment effects, i.e., RS bread intake versus the control bread. There were no significant differences in insulin or C-reactive protein levels due to treatment, gender, or sequence effects. Mean homeostasis model assessment of insulin resistance decreased to normal values (>2.5) at the end of the 14-week study, although there were no significant treatment effects. The results of this study suggest that African Americans may need to consume more than 12 g/day of RS to lower their risk for type 2 DM.

It's a choice to move forward: women's perceptions about treatment decision making in recurrent ovarian cancer.

OBJECTIVE: This research explores the treatment decision-making (TDM) experiences of women with recurrent ovarian cancer (ROC) with regard to treatment options; their understanding of risks and benefits of various treatment options; the decision-making role they want for themselves and for their oncologist; and the social context of the consultation as it pertains to the decision. METHODS: We conducted semi-structured interviews with 26 women at the time of first recurrence. Through inductive data analysis key themes were identified. RESULTS: Many women describe self-identifying the cancer recurrence fairly quickly due to new symptoms. Many feel that the goal for treating their recurrence is to control versus cure the cancer. They describe the subsequent process of diagnosis and TDM for ROC as quick and straightforward with all women accepting the oncologists' treatment recommendation. They feel that the type and number of treatment options are limited. They have a strong desire for physician continuity in their care. Participants feel that their doctor's recommendations as well as their previous experience with ovarian cancer are strong factors influencing their current TDM process. CONCLUSIONS: Shared decision making is based on a simultaneous participation of both the physician and patient in TDM. When faced with ROC, women feel that their doctor's recommendation and their past experience with treatment and TDM are prominent factors influencing the current TDM process.

Women's perceptions about treatment decision making for ovarian cancer.

OBJECTIVES: To identify in women with advanced epithelial ovarian cancer who had just undergone surgery the extent to which they (1) perceived that they had treatment options, (2) understood the treatment related risks and benefits, and (3) preferred to participate in the treatment decision-making process. METHODS: This qualitative study included women who underwent initial surgery for stage 3 or 4 ovarian cancer and who had received less than two cycles of chemotherapy. In depth semistructured interviews were conducted with 21 patients between June 1999 and February 2001. The interviews were content analyzed according to the themes that arose in the interview. RESULTS: Five themes were identified. (1) Knowledge of treatment benefits and risks. Women understood that the treatment had both survival and quality of life benefits. Women could clearly articulate the risks of chemotherapy. (2) Readiness to make a decision. When making treatment decisions, women described being overwhelmed by the effects of concurrent drugs like analgesics, the severity of the illness, unexpected diagnosis of cancer and grief, and feeling pressured into a decision. (3) Perception of a treatment choice. Most women felt that they made their treatment decision; however, most women did not perceive that they had a treatment choice. Thus, treatment decision making is really a process of coming to terms with the disease and the recommended treatment. (4) Physician-patient relationship. All women suggest that their doctor knew the right treatment for them and they felt confident in their cancer physician. (5) Social supports. Women described supports through decision-making processes that included individuals who advocated for them, faith, and past experience with the cancer system. Hindrances to decision making included people who were negative, the cancer label, and employers. CONCLUSIONS: Women with advanced epithelial ovarian cancer did not describe the treatment decision-making process as shared; rather they described an interaction that was directed largely by the physician. These women attribute this form of decision-making to their advanced age, severity of illness, immediate ramification of treatment choices, and lack of advocacy for a different model of interaction. Thus, the onus is on the physician to ensure that there is an environment for shared decision-making in the event that the patient is interested in such an interaction.

Spatial location in color vision.

Ross argues that the location problem for color-the problem of how it is represented as occupying a particular location in space-constitutes an objection to color subjectivism. There are two ways in which the location problem can be interpreted. First, it can be read as a why-question about the relation of visual experience to the environment represented: Why does visual experience represent a patch of color as located in this part of space rather than that? On this interpretation, the subjectivist can answer Ross's objection by appealing to the physical location of reflectance rather than color. Second, it can be read as a how-question about visual representation itself: How does visual experience put together the experience of a color with the experience of its being located in space? This version makes the location problem a problem about visual experience itself and renders the ontology of color irrelevant to its solution. The location problem is thus no more a problem for the color subjectivist than for the color realist.

Comparison of the effects of dopaminergic and serotonergic activity in the CNS on the activity of the immune system.

This work demonstrates that the natural killing function of the innate immune system is affected in psychiatric disorders related primarily to serotonergic pathways in the CNS rather than to psychiatric disorders which involve mainly dopaminergic pathways. Only depressive patients demonstrated low natural killer (NK) cell activity, which is inversely correlated to the intensity of depression and could be reversed by serotonin selective re-uptake inhibitors concomitant with clinical improvement. This phenomenon is absent in Parkinson's and schizophrenic patients, in whom no reduction in NK activity was observed. Also, no effect on NK activity could be demonstrated following the specific respective treatments by dopamine (D2) blockers or agonists.

A neuron doctrine in the philosophy of neuroscience.

Many neuroscientists and philosophers endorse a view about the explanatory reach of neuroscience (which we will call the neuron doctrine) to the effect that the framework for understanding the mind will be developed by neuroscience; or, as we will put it, that a successful theory of the mind will be solely neuroscientific. It is a consequence of this view that the sciences of the mind that cannot be expressed by means of neuroscientific concepts alone count as indirect sciences that will be discarded as neuroscience matures. This consequence is what makes the doctrine substantive, indeed, radical. We ask, first, what the neuron doctrine means and, second, whether it is true. In answer to the first question, we distinguish two versions of the doctrine. One version, the trivial neuron doctrine, turns out to be uncontroversial but unsubstantive because it fails to have the consequence that the nonneuroscientific sciences of the mind will eventually be discarded. A second version, the radical neuron doctrine, does have this consequence, but, unlike the first doctrine, is highly controversial. We argue that the neuron doctrine appears to be both substantive and uncontroversial only as a result of a conflation of these two versions. We then consider whether the radical doctrine is true. We present and evaluate three arguments for it, based either on general scientific and philosophical considerations or on the details of neuroscience itself, arguing that all three fail. We conclude that the evidence fails to support the radical neuron doctrine.

[Cutaneous larva migrans].

Larva migrans is a rare cutaneous parasitic infestation, whose incidence in Israel has increased over the past few years. This is mainly due to the growing number of Israelis traveling to the Far East and to Central and South America. We present 4 such cases. The treatment of choice for this parasite is thiabendazole, an imidazole with anthelminthic properties.

A short-term psychiatric inpatient program for adolescents.

Third-party payers have become increasingly unwilling to fund long-term hospitalizations for adolescents. Inpatient adolescent programs have had to develop strategies to treat this difficult patient population much more rapidly. In late 1989 a short-term adolescent treatment program, known as the STAT program, was developed and implemented at a private psychiatric hospital in Massachusetts. The program aimed for a two- to three-week length of stay, a reduction of 30 to 50 percent. To accomplish this goal, the program shifted from a treatment-based approach to a focus on crisis management, patient evaluation and stabilization, and transition to outpatient services. Many staff concerns were allayed during the program's implementation. Short-term treatment for adolescents can be viable if appropriate exclusion criteria are developed for admissions and an adequate range of outpatient treatment services are available.

Training issues for a female psychiatric residency cohort.

A three-year retrospective study of the training experiences of an all-female psychiatric residency cohort was conducted, using questionnaires and interviews, to understand the perspectives of both the residents and faculty. The study of this cohort provided a forum in which to take a close look at issues for women trainees in psychiatry. Residents reported being more aware of the group's homogeneity than those who interacted with them said they were, and "feminine" group dynamics were described. The residents were concerned about their professional image and were unaware that they were well regarded by male faculty. This study highlights the need for more female role models as well as for more sharing of perceptions during the training of female psychiatric residents.

Developing a unit for mentally retarded-mentally ill patients on the grounds of a state hospital.

For some time patients with the dual diagnosis of mental retardation and mental illness have been recognized as a distinct patient population, but development of programs meeting their special needs is slow. In October 1986 a Massachusetts state psychiatric facility opened a rehabilitative program for such patients in a separate 40-bed unit on the hospital grounds. All patients admitted to the Specialized Habilitative and Rehabilitative Environment (SHARE) program had long histories of institutionalization, and many had been treated with neuroleptic drugs for several years. Most patients now attend day programming, and a few have been able to move on to less restrictive environments. Patients' average neuroleptic dosage has been substantially reduced. This progress has been made in spite of such program-development problems as the need to change staff's long-held perspectives about dual-diagnosis patients, lack of funding, and high staff turnover.

Psychiatric screening in the emergency department: its effect on physician behavior.

The purpose of our prospective, controlled study was to determine whether providing the results of a psychiatric screening instrument, the General Health Questionnaire (GHQ), to emergency physicians would result in a change in the detection and management of patients with psychosocial problems. Five hundred ninety-nine emergency department patients were enrolled, 242 in the control and 357 in the intervention group. Noncritical patients, selected by presenting complaint, were given the GHQ to complete before physician evaluation; those whose GHQ scores were high (10 or higher) were identified as having a greater likelihood of having psychosocial problems. During the intervention phase, physicians were provided the patient's GHQ score before beginning their evaluation, as well as a specific mechanism for psychosocial referral. A significantly greater proportion of patients with high GHQ scores in both study groups were judged by physicians to have a psychiatric problem (P less than .0001). During the intervention phase, patients with high scores more frequently were assigned a psychiatric diagnosis (14.1% vs 7.7%) and received psychosocial referral (36.1% vs 5.7%). However, only the latter difference was statistically significant (P less than .0001). The majority (85.7%) of patients offered psychosocial referral accepted their referral. There was no difference in the number of laboratory tests ordered or medical/surgical referrals requested between patients in the control or intervention groups with high scores. Therefore, providing GHQ results to emergency physicians led to more frequent psychiatric diagnoses and psychosocial referrals of patients with high GHQ scores but did not alter their medical management.

[Pemphigus vegetans, a rare variant of pemphigus vulgaris].

Pemphigus vegetans is a variant of pemphigus vulgaris with different clinical manifestations. Diagnosis may be difficult because of the varied presentations. A 46-year-old woman with this condition had been treated for Behcet's disease because of oral lesions. On admission, prior to dermatological consultation, she was thought to have an infectious disease. The diagnosis of pemphigus vegetans was confirmed by histological and immunofluorescence studies.

Neurogenic bladder due to herpes zoster infection in an infant.

A case is presented of Herpes zoster (HZ) infection in a 2.5-month-old infant with the added complication of a neurogenic bladder. The patient's mother suffered from varicella during the 18th week of pregnancy. The patient had a typical herpetic rash at the age of 2.5 months, and developed constipation and a neurogenic bladder. While the constipation improved, bladder atonicity led to hydroureters necessitating bilateral ureterostomies. Urinary tract involvement of HZ is well known in adults and is reversible. To our knowledge this is the first report of such a complication of HZ infection in infants.

The emergency department ECG and immediately life-threatening complications in initially uncomplicated suspected myocardial ischemia.

The emergency physician's disposition of patients with suspected myocardial ischemia is currently debated; some physicians believe that a subgroup of patients can be managed safely outside the coronary care unit. Clinical predictors are needed in assessing the patient with suspected myocardial ischemia to help identify this subgroup. Through a retrospective cohort study, we investigated the value of the initial emergency department ECG in discriminating between chest pain patients with low and high risk for immediately life-threatening complications. Two hundred eleven initially uncomplicated consecutive coronary care unit admissions with suspected unstable angina or myocardial infarction were studied. Patient outcome, including the incidence of myocardial infarction, complications, and mechanical and pharmacologic interventions, was reviewed. Immediately life-threatening complications included ventricular fibrillation, ventricular tachycardia, shock, 2 degrees and 3 degrees block, and death. Mechanical interventions included electrocardioversion or defibrillation, endotracheal intubation, intra-aortic balloon pump, Swan-Ganz catheter, or pacemaker insertion. Pressors, antiarrhythmics, and vasodilators were the reviewed pharmacologic interventions. A positive ECG was defined by the presence of ST elevation or depression, T wave inversion, left ventricular hypertrophy, left bundle branch block, paced rhythm, or new Q waves. All other ECG interpretations were considered negative. Patients were divided into two groups based on this initial emergency physician ECG interpretation and their complication incidences compared. Of the 211 patients, 96 had a positive ECG; 115 had negative ECGs. Patients with positive ECGs were older, had a greater history and concurrent incidence of myocardial infarction, and more complications and intensive interventions.(ABSTRACT TRUNCATED AT 250 WORDS)
