Psychological interventions for depression and anxiety in pregnant Latina and Black women in the United States: A systematic review

Black women and Latinas have more symptoms of depression and anxiety during pregnancy than do their non‐Latina White counterparts. Although effective interventions targeting internalizing disorders in pregnancy are available, they are primarily tested with White women. This article reviews randomized controlled trials and non‐randomized studies to better understand the effectiveness of psychological interventions for anxiety and depression during pregnancy in Latinas and Black women. Additionally, this review summarizes important characteristics of interventions such as intervention format, treatment modality, and the use of cultural adaptations. Literature searches of relevant research citation databases produced 68 studies; 13 of which were included in the final review. Most studies were excluded because their samples were not majority Latina or Black women or because they did not test an intervention. Of the included studies, three interventions outperformed a control group condition and showed statistically significant reductions in depressive symptoms. An additional two studies showed reductions in depressive symptoms from pretreatment to post‐treatment using non‐controlled designs. The remaining eight studies (seven randomized and one non‐randomized) did not show significant intervention effects. Cognitive behavioral therapy was the modality with most evidence for reducing depressive symptoms in pregnant Black and Latina women. No intervention was found to reduce anxiety symptoms, although only two of the 13 measured anxiety as an outcome. Five studies made cultural adaptations to their treatment protocols. Future studies should strive to better understand the importance of cultural modifications to improve engagement and clinical outcomes with pregnant women receiving treatment for anxiety and depression.     

The effectiveness of a treatment protocol for male lower urinary tract symptoms in general practice: a practical randomised controlled trial

BACKGROUND: Randomised controlled trials have shown the efficacy of several treatment modalities for lower urinary tract symptoms (LUTS) in selected populations. The effectiveness in daily practice has hardly been investigated, especially in primary care and is dependent on choices between all possible treatment options and best investigated in a comprehensive study, including all treatment modalities (watchful waiting, alpha-blockers, 5-alpha-reductase inhibitors, and surgery). AIM: Assessment of the effectiveness of a comprehensive treatment protocol for LUTS in primary care. DESIGN OF STUDY: Randomised controlled trial. SETTING: Fourteen general practices in the Netherlands. METHOD: Intervention: treatment protocol based on a formalised expert opinion. Control condition: usual care. Study population: 208 subjects with moderate to severe LUTS (IPSS > or =8, median = 13). OUTCOME MEASURES: symptom severity (IPSS [International Prostate Symptom Score]), bother score (Dan-PSS [Danish Prostate Symptom Score]), and maximum urinary flow (Q(max)); incidence of acute urinary retention and urinary tract infections. RESULTS: In the intervention group markedly more subjects used an alpha-blocker at end of follow-up than in the usual care group (24% versus 6%). No significant differences were found between intervention and control group in IPSS, Q(max) or Dan-PSS. CONCLUSION: alpha-blockers and watchful waiting are the most frequent treatment modalities for LUTS in primary care. Our study showed no evidence that a protocol using well-defined indications for all possible treatment modalities based on a formalised expert opinion procedure has added value. Based on our results, we cannot recommend a broadening of the indication for alpha-blockers, which, however, seems to be the current trend.     

Serum levels of insulin-like growth factor binding proteins in Ecuadorean children with growth hormone insensitivity

Burren CP, Wanek D, Mohan S, Cohen P, Guevara-Aguirre J, Rosenfeld RG. Serum levels of insulin-like growth factor binding proteins in Ecuadorean children with growth hormone insensitivity. Acta Pædiatr 1999; Suppl 428: 185–91. Stockholm. ISSN 0803–5326
Although insulin-like growth factor binding proteins (IGFBPs) are known to be important modulators of the action of insulin-like growth factors (IGFs), regulation of their production in vivo is not completely understood. Serum concentrations of IGFBP-3, -4 and -5 and acid-labile subunit (ALS) were therefore examined in 20 children with growth hormone (GH) insensitivity before and after 6 months of therapy with recombinant human IGF-I (80 or 120 ug/kg twice daily). The IGFBP concentrations in these children were compared with those in 62 GH-deficient children receiving GH therapy for 3 months. Serum levels of IGFBP-3, -4 and -5 and ALS all increased significantly ( p < 0.0001) in GH-deficient children in response to GH therapy, whereas no significant increases occurred in the children with GH insensitivity. These findings indicate that GH is responsible for the regulation of serum levels of IGFBP-3, -4 and -5 and ALS, and that IGF-I does not directly regulate the concentrations of these circulating IGFBPs. □ Growth hormone, growth hormone insensitivity, insulin-like growth factor I, insulin-like growth factor binding protein     

Natural genetic variation caused by small insertions and deletions in the human genome

Human genetic variation is expected to play a central role in personalized medicine. Yet only a fraction of the natural genetic variation that is harbored by humans has been discovered to date. Here we report almost 2 million small insertions and deletions (INDELs) that range from 1 bp to 10,000 bp in length in the genomes of 79 diverse humans. These variants include 819,363 small INDELs that map to human genes. Small INDELs frequently were found in the coding exons of these genes, and several lines of evidence indicate that such variation is a major determinant of human biological diversity. Microarray-based genotyping experiments revealed several interesting observations regarding the population genetics of small INDEL variation. For example, we found that many of our INDELs had high levels of linkage disequilibrium (LD) with both HapMap SNPs and with high-scoring SNPs from genome-wide association studies. Overall, our study indicates that small INDEL variation is likely to be a key factor underlying inherited traits and diseases in humans.     

Evaluation of the anticonvulsant and muscle relaxant effects of the methanol root bark extracts of Annona senegalensis

ObjectiveTo investigate the potentials of the root bark of Annona (A.) senegalensis in the control of seizure and related hypnotic and motor incoordination effects in mice using experimental models.MethodsThe methanol extract (ME) of the root bark of A. senegalensis was studied in mice using pentylenetetrazole (PTZ) induced convulsions, phenobarbitone induced sleeping time and motor coordination test on rota-rod performance. Acute toxicity and lethality (LD₅₀) test as well as phytochemical analysis were also carried out.ResultsThe extract (200, 400, 800 mg/kg) exhibited a non-dose dependent significant (P <0.05) delay in the onset of both tonic and clonic phases of seizure induced by PTZ (60 mg/kg, s.c.) as well as offered a 100% protection (200 mg/kg) in mice from PTZ induced seizures. The extract significantly (P <0.05) decreased the latency and increased the duration of phenobarbitone induced sleeping time. At 200 mg/kg, the extract exhibited a significant (P <0.05) motor incoordination. The acute toxicity test revealed an oral LD₅₀ of 1 296 mg/kg, while the phytochemical studies showed the presence of alkaloids, resins, glycosides, carbohydrate, reducing sugar, flavonoids, terpenoids, saponins and tannins.ConclusionThe extract of A. senegalensis possessed anticonvulsant activity with pronounced hypnotic and muscle relaxant effects.     

Predicting protein cellular localization using a domain projection method

We investigate the co-occurrence of domain families in eukaryotic proteins to predict protein cellular localization. Approximately half (300) of SMART domains form a "small-world network", linked by no more than seven degrees of separation. Projection of the domains onto two-dimensional space reveals three clusters that correspond to cellular compartments containing secreted, cytoplasmic, and nuclear proteins. The projection method takes into account the existence of "bridging" domains, that is, instances where two domains might not occur with each other but frequently co-occur with a third domain; in such circumstances the domains are neighbors in the projection. While the majority of domains are specific to a compartment ("locale"), and hence may be used to localize any protein that contains such a domain, a small subset of domains either are present in multiple locales or occur in transmembrane proteins. Comparison with previously annotated proteins shows that SMART domain data used with this approach can predict, with 92% accuracy, the localizations of 23% of eukaryotic proteins. The coverage and accuracy will increase with improvements in domain database coverage. This method is complementary to approaches that use amino-acid composition or identify sorting sequences; these methods may be combined to further enhance prediction accuracy.     

Inferior Vena Caval and Right Atrial Thrombosis Complicating an Amebic Hepatic Abscess

We describe a 50-yr-old black laborer who presented with right lower chest pain, weight loss, and pedal edema. Ultrasonography and computed tomograms showed a large abscess cavity in the right lobe of the liver which extended very close to the inferior vena cava. The lumen of the adjacent inferior vena cava was partially occluded by thrombus, which could be traced up into the cavity of the right atrium. The hepatic veins were normally patent. Sterile blood-stained pus was aspirated from the abscess. Antibodies against Entamoeba histolytica were present in high titer in the patient's serum. Although propagation of hepatocellular carcinoma into the inferior vena cava and even up into the right atrium is well recognized, inferior vena caval thrombosis extending up into the right atrium has not hitherto been reported as a complication of amebic hepatic abscess.
