Addressing child undernutrition in Tanzania with the ASTUTE program.

BACKGROUND: Optimal infant and young child feeding practices (IYCFP) reduce childhood stunting and are associated with additional health benefits. In Tanzania, IYCFP are far from optimal where 32% of children under the age of 5 years are stunted. The purpose of this study was to examine whether behavior change communication focused on reducing child undernutrition was associated with improved IYCFP in Tanzania. METHODS: A cross-sectional survey was administered to approximately 10,000 households with children under the age of 2 at baseline and endline. Bivariate analyses and logistic regression was used to examine the relationship between exposure to behavior change communication and timely initiation of breastfeeding, exclusive breastfeeding, continued breastfeeding at one year, timely complementary feeding (CF), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD). RESULTS: Mothers who heard a radio spot about IYCFP were more likely than mothers who had not heard a radio spot about IYCFP to begin complementary foods at six months. Their children were also more likely to achieve MMF, MDD, and MAD with odds ratios of 2.227 (p = 0.0061), 1.222 (p = 0.0454), 1.618 (p = < .0001), and 1.511 (p = 0.0002), respectively. Mothers who saw a TV spot about IYCFP were more likely to have greater odds of knowing when to begin complementary feeding, feeding their child a minimally diverse diet (4 food groups or more), and serving a minimum acceptable diet with odds ratios of 1.335 (p = 0.0081), 1.360 (p = 0.0003), and 1.268 (p = 0.0156), respectively. CONCLUSION: Exposure to behavior change communication in Tanzania was generally associated with some increased knowledge of optimal IYCFP as well as practicing IYCF behaviors. Behavior change communication planners and implementers may want to consider conducting similar campaigns as an important component of behavior change to reduce undernutrition and poor health outcomes in developing settings.

Sequences of emotions in patients with borderline personality disorder.

OBJECTIVE: To investigate sequences of emotions (temporal dependence of emotions) to identify specific patterns of borderline personality disorder (BPD). METHOD: The perceived emotions of 50 BPD patients and 50 healthy controls (HC) were monitored by using a hand-held computer system for a 24-h period in a daily life setting. Participants were prompted four times per hour to assess their current perceived emotions. Differences between BPD patients and HC in terms of activation, persistence and down-regulation of emotions were analyzed. RESULTS: Healthy controls in contrast to BPD patients more often activated joy and interest. BPD patients more often experienced persistence of anxiety and sadness. BPD patients more frequently switched from anxiety to sadness, from anxiety to anger and from sadness to anxiety. Anger was predominantly preceded by anxiety. CONCLUSION: Persistence of sadness and anxiety, as well as emotional oscillating between anxiety, sadness and anger are important aspects of the emotional dysregulation in BPD patients.

Climatic, temporal, and geographic characteristics of respiratory syncytial virus disease in a tropical island population.

Respiratory syncytial virus (RSV) is an important cause of morbidity in children worldwide, although data from equatorial regions are limited. We analysed climatic, spatial, and temporal data for children presenting to hospitals in Lombok island, Indonesia with clinical pneumonia. During the study period, 2878 children presented and 741 RSV cases were identified. In multivariate analysis with an 8-day lag, occurrence of rain was associated with 64% higher incidence of RSV disease [incidence rate ratio (IRR) 1.64, 95% confidence interval (CI) 1.13-2.38]. A 1% rise in mean relative humidity and 1 degree C increase in mean air temperature was associated with a 6% (IRR 1.06, 95% CI 1.03-1.10) and 44% (IRR 1.44, 95% CI 1.24-1.66) increase in RSV cases, respectively. Four statistically significant local clusters of RSV pneumonia were identified within the annual island-wide epidemics. This study demonstrates statistical association of monsoon-associated weather in equatorial Indonesia with RSV. Moreover, within the island-wide epidemics, localized RSV outbreaks suggest local factors influence RSV disease.

A longitudinal study of changes in respiratory status in young adults, 1993-2001.

SETTING: There is little information regarding the prognosis of respiratory symptoms in early adulthood or the effects of potential risk factors. OBJECTIVE: To observe changing respiratory morbidity in a group of young adults over a period of 6-8 years. DESIGN: Subjects responding to three or more consecutive postal respiratory surveys carried out between 1993 and 2001 were included in the study. In addition to asthma (defined by a validated scoring system), two symptoms were examined: wheeze and being woken by cough. Five outcomes were defined: persistent, remission, new onset, never and intermittent. RESULTS: Of 2693 subjects who responded to at least one survey, about one third were eligible for inclusion: 10.2% reported wheeze at each survey (persistent) and 3.6% had persistent asthma. Persistent wheeze was seen in almost half (46.7%) of those reporting the symptom at their first survey. The corresponding figure for asthma was 32%. New onset wheeze was found in 16.2% of subjects without wheeze at baseline (asthma 9.7%). Smoking was significantly associated with new onset wheeze (OR 1.97, 95% CI 1.30-3.00) and asthma (OR 2.14, 95% CI 1.26-3.50), but not with persistent symptoms. CONCLUSION: These findings highlight the importance of policies to reduce smoking prevalence in young adults, and will help in the planning of future health care.

Experimental demonstration, using polarized Raman and infrared spectroscopy, that both conventional and de Vries smectic-A phases may exist in smectic liquid crystals with a first-order A-C* transition.

Two models exist for the orientational distribution of the long molecular axes in smectic-A liquid crystals: the conventional unimodal distribution and the "cone-shaped" de Vries distribution. The de Vries hypothesis provides a plausible picture of how, at a molecular level, a first-order Sm-A to Sm-C* transition may occur, especially if there is little or no concomitant shrinkage of the layer spacing. This work investigates two materials with such transitions: C7 and TSiKN65. The azimuthal distribution of in-layer directors is probed using IR and polarized Raman spectroscopy, which allows us to obtain orientational order parameters. In C7, we observe a discontinuous change in the order parameter, the magnitude of which is small compared with the corresponding change in the in-layer director tilt angle Theta . Assuming that the smectic-A liquid crystal is of the de Vries type, we calculate the Theta required to reproduce the apparent order parameter app, obtained from IR, by using the true order parameter , obtained from polarized Raman scattering. The results indicate that, for C7, the tilt angle so calculated is much smaller than that in the Sm-C* angle and hence de Vries behavior may not be the appropriate explanation in this case. Conversely, we find that TSiKN65 shows a different behavior to C7, which can be explained in terms of the de Vries concept. Thus, we conclude that either type of distribution may exist in Sm-A phases which undergo a first-order transition to the Sm-C* phase. We also discuss the changes in the smectic layer spacing and the orientational order parameters across the Sm-A-Sm-C* phase transition, together with changes in birefringence with applied electric field.

Aversive tension in patients with borderline personality disorder: a computer-based controlled field study.

OBJECTIVE: This study was designed to examine the subjective appraisal of aversive tension under conditions of daily life in patients with borderline personality disorder (BPD). METHOD: A sample of 63 female subjects with BPD and 40 mentally healthy controls were each given a hand-held computer. For two consecutive days, participants were prompted at hourly intervals to record their current state of aversive tension and prompting events. RESULTS: Compared with controls, states of aversive tension occurred significantly more frequently in BPD patients. The average levels of aversive tension were significantly higher, and the rate of increase in tension was markedly more rapid. Furthermore, states of aversive tension persisted for a longer period. Among BPD subjects three events (rejection, being alone, and failure) account for 39% of all events preceding states of tension. CONCLUSION: The study provides support for the theory that patients with BPD experience more frequent, stronger, and longer-lasting states of aversive tension.

Prevalence of respiratory symptoms in under 5s: 1993 to 2001.

AIM: To describe changes in the prevalence of respiratory symptoms in 1-4 year olds in two general practice populations observed on four occasions over an eight year period. METHODS: In 1993, 1995, 1999, and 2001, questionnaires were posted to the parents of patients aged 15 years or younger and registered with either of two general practices. Only children aged 1-4 years at time of questionnaire completion were included in this study. For each survey, the prevalence of five key variables was determined. RESULTS: The response rates for all children in the four surveys were 72.8%, 70.6%, 65.0%, and 60.7% respectively. When respondents aged 1-4 years old were stratified into one-year age bands, there was a decrease in the prevalence of symptoms over the study period. This was statistically significant for wheeze and night cough in 2 year olds and for night cough in 4 year olds. Repeated antibiotic prescriptions decreased significantly for 2 and 3 year olds. There were no changes in the prevalence of hay fever or eczema and family history of asthma. CONCLUSIONS: The downward trend in symptom prevalence might represent a real decrease in symptoms or improvements in treatment. In the absence of changes in the prevalence of hay fever and family history of asthma, the downward trend in symptom prevalence may suggest changes in the prevalence of conditions other than asthma.

Chiral polymer hexatics: a new twist on DNA.

Theories of the " N+6" hexagonally ordered phase of DNA are generally based on treatments of hexatic order in smectic systems. Thus N+6 phases should be analogous to superconductors and should expel twist of the nematic director, in an analogy of the Meissner effect. However, in N+6 systems there is no smectic order, hence a radically different mathematical description is required. Here I present the appropriate theory and show that, as N+6 phases are not analogous to superconductors, they can exhibit twist in any direction, without forming any topological defects.

The application of dialectical behavior therapy for patients with borderline personality disorder on inpatient units.

Inpatient treatment of individuals with borderline personality disorder (BPD) is typically fraught with difficulty and failure. Patients and staff often become entangled in intense negative therapeutic spirals that obliterate the potential for focused, realistic, and effective treatment interventions. We describe an inpatient treatment approach to BPD patients which is an application of Dialectical Behavior Therapy (DBT), a cognitive-behavioral therapy for patients with BPD which has been shown to be effective in reducing suicidal behavior, hospitalization, and treatment dropout and improving interpersonal functioning and anger management. The inpatient DBT staff creates a validating treatment milieu and focuses on orienting and educating new patients and identifying and prioritizing their treatment targets. Inpatient DBT treatment techniques include contingency management procedures, skills training and coaching, behavioral analysis, structured response protocols to suicidal and egregious behaviors on the unit, and consultation team meetings for DBT staff.

Dialectical behavior therapy for personality disorders.

Interest in dialectical behavior therapy (DBT) as a treatment for personality disorders has increased dramatically in recent years. Although originally designed for the outpatient treatment of suicidal individuals with borderline personality disorder (BPD), DBT has been applied to many more diverse populations including comorbid substance dependence and BPD, inpatient treatment for BPD, as well as antisocial behaviors in juveniles and adults. This paper provides a brief overview of DBT, presents and evaluates the most recent literature on the application of DBT to the treatment of personality disorders, and highlights some of the current controversies surrounding the use of DBT.

Dialectical behavior therapy for binge eating disorder.

This study evaluated the use of dialectical behavior therapy (DBT) adapted for binge eating disorder (BED). Women with BED (N = 44) were randomly assigned to group DBT or to a wait-list control condition and were administered the Eating Disorder Examination in addition to measures of weight, mood, and affect regulation at baseline and posttreatment. Treated women evidenced significant improvement on measures of binge eating and eating pathology compared with controls, and 89% of the women receiving DBT had stopped binge eating by the end of treatment. Abstinence rates were reduced to 56% at the 6-month follow-up. Overall, the findings on the measures of weight, mood, and affect regulation were not significant. These results support further research into DBT as a treatment for BED.

Evaluation of inpatient dialectical-behavioral therapy for borderline personality disorder--a prospective study.

Dialectical-Behavioral Therapy for Borderline Personality Disorder (DBT) developed by M. Linehan is specifically designed for the outpatient treatment of chronically suicidal patients with borderline personality disorder. Research on DBT therapy, its course and its results has focused to date on treatments in an outpatient setting. Hypothesizing that the course of therapy could be accelerated and improved by an inpatient setting at the beginning of outpatient DBT, we developed a treatment program of inpatient therapy for this patient group according to the guidelines of DBT. It consists of a three-month inpatient treatment prior to long-term outpatient therapy. In this pilot study 24 female patients were compared at admission to the hospital, and at one month after discharge with respect to psychopathology and frequency of self-injuries. Significant improvements in ratings of depression, dissociation, anxiety and global stress were found. A highly significant decrease in the number of parasuicidal acts was also reported. Analysis of the average effect sizes shows a strong effect which prompts the development of a randomized controlled design.

Research on dialectical behavior therapy for patients with borderline personality disorder.

Research evidence to date indicates that, although DBT was developed for the treatment of patients with suicidal behavior, it can be adapted to treat BPD patients with comorbid substance-abuse disorder and be extended to other patient populations and the treatment of other disorders. Across studies, DBT seems to reduce severe dysfunctional behaviors that are targeted for intervention (e.g., parasuicide, substance abuse, and binge eating), enhance treatment retention, and reduce psychiatric hospitalization. Evidence suggests that additional research is warranted to examine which components of DBT contribute to outcomes. Although preliminary, skills coaching seems to be a crucial ingredient in producing reductions in parasuicidal behavior, and specific strategies (e.g., validation, balance of change, and acceptance interventions) may play an important role in positive behavioral change. Several investigators are evaluating the efficacy of DBT. For example, Asberg et al at the Karolinska Institute in Sweden have begun a pilot study comparing DBT for women who have made multiple suicide attempts to transference focus psychotherapy, a psychodynamic therapy developed by Kernberg. They have planned a randomized clinical trial to compare DBT and transference focus psychotherapy with TAU in the community. van den Bosch has completed a randomized clinical trial for women who met criteria for BPD and substance abuse comparing DBT-S with TAU. Lynch is conducting a randomized clinical trial examining the efficacy of DBT skills training plus medication versus medication only for the treatment of moderate to severe depression in the elderly. Results from these studies should become available over the next several years, providing further empiric evidence by which to evaluate the efficacy of DBT. Additional development of DBT seems warranted to improve its efficacy, and additional investigation is needed to establish its effectiveness in public health settings. Analyses from existing data sets of factors that predict treatment response and elements of the treatment that contribute to outcome are needed. Also, longitudinal follow-up studies to determine suicide rates and maintenance of treatment gains are needed. Because DBT has been adopted in a variety of clinical settings, effectiveness studies are needed. Given the difficulty of conducting treatment research with chronically suicidal individuals, perhaps the largest challenge to further treatment development is recruiting young investigators who are willing to conduct research in this area. Nevertheless, in the 6 years since the treatment manuals were published, DBT seems to be a step toward more effective treatment for severely multidisordered patients.

Dialectical behavior therapy for patients with borderline personality disorder and drug-dependence.

A randomized clinical trial was conducted to evaluate whether Dialectical Behavior Therapy (DBT), an effective cognitive-behavioral treatment for suicidal individuals with borderline personality disorder (BPD), would also be effective for drug-dependent women with BPD when compared with treatment-as-usual (TAU) in the community. Subjects were randomly assigned to either DBT or TAU for a year of treatment. Subjects were assessed at 4, 8, and 12 months, and at a 16-month follow-up. Subjects assigned to DBT had significantly greater reductions in drug abuse measured both by structured interviews and urinalyses throughout the treatment year and at follow-up than did subjects assigned to TAU. DBT also maintained subjects in treatment better than did TAU, and subjects assigned to DBT had significantly greater gains in global and social adjustment at follow-up than did those assigned to TAU. DBT has been shown to be more effective than treatment-as-usual in treating drug abuse in this study, providing more support for DBT as an effective treatment for severely dysfunctional BPD patients across a range of presenting problems.

Birt-Hogg-Dubé syndrome: a novel marker of kidney neoplasia.

BACKGROUND: Birt-Hogg-Dubé syndrome (BHD) is a dominantly inherited predisposition for development of fibrofolliculomas, trichodiscomas, and acrochordons. Concurrent internal tumors, such as colonic polyps and renal carcinoma, have been described in patients with BHD. OBJECTIVE: To evaluate kindreds with familial renal tumors for cutaneous manifestations of BHD. DESIGN: One hundred fifty-two patients from 49 families underwent complete oral and skin examination. Skin lesions were identified by their clinical appearance, and the diagnosis was confirmed by results of histologic examination. Individuals underwent screening for familial renal neoplasms. SETTING: A tertiary referral research hospital. PATIENTS: Individuals with familial renal tumors and their asymptomatic at-risk relatives. MAIN OUTCOME MEASURE: We determined whether any form of renal cancer is associated BHD. RESULTS: We identified 3 extended kindreds in whom renal neoplasms and BHD appeared to segregate together. Two kindreds had renal oncocytomas and a third had a variant of papillary renal cell carcinoma. Thirteen patients exhibited BHD. Seven individuals, including a set of identical twins, had renal neoplasms and BHD. An additional 4 patients (3 deceased and not examined) in these families had renal neoplasms but not BHD. Birt-Hogg-Dubé syndrome without renal neoplasms was present in 6 individuals. Thirteen patients with fibrofolliculomas and trichodiscomas presented clinically with multiple smooth skin-colored to grayish-white papules located on the face, auricles, neck, and upper trunk. Oral papules were present in 9 of 28 and achrochordons in 11 of 28 patients. Features of BHD not previously appreciated included deforming lipomas in 5, collagenomas in 4, and pulmonary cysts in 4 of 28 patients. Families with BHD did not display germline mutations in the von Hippel-Lindau gene or in the tyrosine kinase domain of the MET proto-oncogene. CONCLUSIONS: Birt-Hogg-Dubé syndrome may be associated with familial renal tumors. Birt-Hogg-Dubé and renal tumors segregate together in an autosomal dominant fashion. Patients with BHD and their relatives are at risk for development of renal tumors. Therefore, patients with BHD and their relatives should undergo abdominal computed tomography and renal ultrasound screening for renal tumors.

Facial expression recognition ability among women with borderline personality disorder: implications for emotion regulation?

This study examined recognition of facial expressions of emotion among women diagnosed with borderline personality disorder (BPD; n = 21), compared to a group of women with histories of childhood sexual abuse with no current or prior diagnosis of BPD (n = 21) and a group of women with no history of sexual abuse or BPD (n = 20). Facial recognition was assessed by a slide set developed by Ekman and Matsumoto (Japanese and Caucasian Facial Expressions of Emotion and Neutral Faces, 1992), expanded and improved from previous slide sets, and utilized a coding system that allowed for free responses rather than the more typical fixed-response format. Results indicated that borderline individuals were primarily accurate perceivers of others' emotions and showed a tendency toward heightened sensitivity on recognition of fear, specifically. Results are discussed in terms of emotional appraisal ability and emotion dysregulation among individuals with BPD.

The Reasons for Living Inventory for Adolescents (RFL-A): development and psychometric properties.

The role of adaptive beliefs and attitudes against suicide has not been given adequate attention in the clinical or assessment literature. This article reports on the development and initial psychometric properties of a 32-item self-report inventory, the Reasons for Living Inventory for Adolescents (RFL-A). In Phase 1, we used exploratory and confirmatory factor analyses to identify five correlated factors: Future Optimism, Suicide-Related Concerns, Family Alliance, Peer Acceptance and Support, and Self-Acceptance. In Phase 2, we cross-validated the 5-factor oblique model in a different group of adolescents recruited from two high schools. In addition, we examined evidence for convergent, discriminant, and construct validities. The coefficient alpha indices for the RFL-A total and scales were satisfactory. In Phase 3, we evaluated additional evidence of reliability and validity using samples of high school and psychiatric inpatient adolescents. The results suggest that the RFL-A is a short, reliable, and valid measure that is potentially useful in the assessment of adolescent suicidal behavior.

The FHIT gene product is highly expressed in the cytoplasm of renal tubular epithelium and is down-regulated in kidney cancers.

Loss of heterozygosity and homozygous deletion of the 3p14.2 region in human cancers implies the existence of a tumor suppressor gene. One such candidate is the fragile histidine triad (FHIT) gene. To investigate the role of FHIT gene product in tumorigenesis, we generated specific polyclonal antibodies to the human protein and studied its expression in normal and tumor tissues. Immunoblot analysis revealed highly variable expression of pFhit in normal adult human tissues. The highest steady-state level of pFhit was found in kidney and brain, whereas breast, intestine, and skeletal muscle expressed only trace amounts. Within the kidney, the pattern of pFhit immunoreactivity was confined to the tubular epithelium and absent in the glomeruli. Immunofluorescence analysis and biochemical fractionation have sublocalized pFhit to the cytosolic compartment. Compared with normal kidney, pFhit was found to be down-regulated in a subset of primary renal cell carcinoma. Two of 12 renal cell carcinoma cell lines that are known not to contain VHL mutations showed complete loss of pFhit expression. This is supported by the appearance of aberrant reverse transcription-polymerase chain reaction products and loss of the normal-size fragment. Our results are consistent with a potential role of pFhit loss or dysfunction in human renal cell carcinoma independent of VHL involvement.
