Culturally adapted psychosocial interventions (CaPSI) for early psychosis in a low-resource setting: study protocol for a large multi-center RCT.

BACKGROUND: Psychosis treatment guidelines recommend cognitive behaviour therapy (CBT) and family intervention (FI), for all patients with first episode psychosis (FEP), though guidance borrows heavily from literature in adults from high income countries. To our knowledge, there are few randomized controlled trials (RCTs) examining the comparative effect of these commonly endorsed psychosocial interventions in individuals with early psychosis from high-income countries and no such trials from low and middle-income countries (LMICs). The present study aims to confirm the clinical-efficacy and cost-effectiveness of delivering culturally adapted CBT (CaCBT) and culturally adapted FI (CulFI) to individuals with FEP in Pakistan. METHOD: A multi-centre, three-arm RCT of CaCBT, CulFI, and treatment as usual (TAU) for individuals with FEP (n = 390), recruited from major centres across Pakistan. Reducing overall symptoms of FEP will be the primary outcome. Additional aims will include improving patient and carer outcomes and estimating the economic impact of delivering culturally appropriate psychosocial interventions in low-resource settings. This trial will assess the clinical-efficacy and cost-effectiveness of CaCBT and CulFI compared with TAU in improving patient (positive and negative symptoms of psychosis, general psychopathology, depressive symptoms, quality of life, cognition, general functioning, and insight) and carer related outcomes (carer experience, wellbeing, illness attitudes and symptoms of depression and anxiety). CONCLUSIONS: A successful trial may inform the rapid scale up of these interventions not only in Pakistan but other low-resource settings, to improve clinical outcomes, social and occupational functioning, and quality of life in South Asian and other minority groups with FEP. TRIAL REGISTRATION: NCT05814913.

Assessment of skeletal relationships in cleft palate with or without cleft lip: A cone-beam computed tomography study in a pakistani population.

Background: Understanding the different skeletal relationships in orofacial clefts by using cone-beam computed tomography (CBCT) may eventually lead to developing better diagnosis and treatment protocols for facial deformities. Aims: The objective of this study was to investigate the different skeletal relationships in the cleft palate with or without cleft lip (CP ± L), using CBCT scans. This is a retrospective study conducted at the Orthodontics and Oral Radiology department, CMH-Lahore medical college and Institute of dentistry. In the current study, 4,152 CBCT scans (dcm format) were collected from a radiology center in Lahore, Pakistan between February 2015 and February 2018. All CBCT scans were imported to the Romexis Viewer, version 4.4.0 (Planmeca, Finland). Data sorting was performed to identify age, sex, cleft phenotype, unilateral cleft quadrant, sagittal skeletal relationship, and facial soft tissue involvement. Materials and Methods: Statistics were generated, using the Chi-square test. A P value <0.05 was considered statistically significant. Results: We identified 73 cases of CP ± L in the sample. The male-to-female ratio was 1.21:1. Bilateral cleft lip and palate (BCLP) mostly affected males (60%), whereas unilateral cleft lip and palate (UCLP) mainly affected females (57.6%), with a left-side female predominance. The different cleft phenotypes do not show any statistically significant difference regarding skeletal relationships and sex (P > 0.05). Conclusions: Skeletal class III relationships were found to be predominant in both sexes, followed by class II, and class I skeletal relationships. Henceforth, such CP ± L patients should be pre-emptively screened in early life to avoid such skeletal complications.

Role of cAMP/PKA/CREB pathway and ß-arrestin 1 in LH induced luteolysis in pregnant rats.

Luteal dysfunction in pregnant women is associated with early pregnancy loss, making the study of structure and function of the corpus luteum (CL) critical. Luteinizing hormone (LH) plays a crucial role in the mammalian female reproduction majorly by regulating luteal development. In rats, the luteotropic roles of LH have been widely investigated but its role in the process of luteolysis has received little attention. In this study, we explored the luteolytic actions of LH during different stages of pregnancy in rats. Repeated administration of LH during the late and mid-stages of pregnancy led to functional luteolysis during both stages, while structural luteolysis was observed only during the late-stage. We analyzed the involvement of cAMP/PKA/CREB pathway, MAP kinases and ß-arrestins to elucidate the molecular mechanism of LH-mediated luteolysis. The results indicate that the repeated administration of LH causes LH/CGR desensitization along with an increase in ß-arrestin 1 expression, while luteal expression of MAP kinases remained unaffected. Further, siRNA-mediated depletion of ß-arrestin 1 in primary luteal-cell cultures prevents initiation of the luteolysis process to some extent during both the stages of pregnancy, underscoring its role in LH mediated-luteolysis. In conclusion, the luteolytic actions of LH appear to involve more than one signaling pathway and cAMP/PKA/CREB pathway appears to be the key regulator. This is the first report to show a positive correlation between ß-arrestin 1 and 20α-hsd expression. These findings have implications for our understanding of the molecular pathways that regulate luteolysis.

Differences in the socio-demographic determinants of undernutrition in children aged <5 years in urban and rural areas of Bangladesh measured by the Composite Index of Anthropometric Failure.

OBJECTIVES: This study investigates the prevalence and determinants of undernutrition among children <5 years living in Bangladesh using the Composite Index of Anthropometric Failure (CIAF) and highlights the differences between urban and rural areas. STUDY DESIGN: Data are drawn from three cross-sectional Bangladesh Demographic Health Surveys conducted from 2007 to 2014. METHODS: A Chi-square test was used to assess the prevalence of <5 years child undernutrition. Logistic regression analysis was performed to identify various sociodemographic risk factors. RESULTS: The prevalence of undernutrition based on the CIAF was 52% among children <5 years in Bangladesh. The prevalence of undernutrition in children living in urban areas and rural areas were found to be 45% and 54%, respectively. As per the CIAF, undernutrition was highly prevalent among children in the older age group, children of uneducated and currently working mothers, those of underweight mothers, children of fourth and above in the birth order, children of fathers who were manual labourers, children of households who had no access to television and those in the poorest households whether in urban or rural areas. Children in the older age group, children of uneducated mothers, those with underweight mothers and those from the poorest households provided common key risk factors for undernutrition in both urban and rural areas. Children of fourth and above birth order and not watching television at all were additional risk factors of child undernutrition in rural areas. CONCLUSION: Half of the children in rural areas and two-fifths of them in urban areas are suffering undernutrition in Bangladesh, and several sociodemographic factors heighten the risks. Also, birth order and watching television were identified as the differential risk factors. This study therefore concludes that evidence-based interventions are needed to reduce the burden of undernutrition in children in the country.

Physiologic Specialization and Genetic Differentiation of Puccinia triticina Causing Leaf Rust of Wheat on the Indian Subcontinent During 2016 to 2019.

Wheat is the second most cultivated cereal crop in the world and is an important crop in India. Leaf (brown) rust, caused by Puccinia triticina, was the most prevalent among the three rusts found in all the wheat-growing areas of India, Bhutan, and Nepal during 2016 to 2019. Leaf rust samples from wheat crops in these countries were pathotyped using the wheat differential genotypes and binomial Indian system of nomenclature. To facilitate international communication, each pathotype identified was also tested using the North American differentials. A total of 33 pathotypes were identified from 1,086 samples, including three new pathotypes: 61R47 (162-5 = KHTPM) and 93R49 (49 = NHKTN) from India and 93R57 (20-1 = NHKTN) from Nepal. Two pathotypes, 121R60-1 (77-9/52 = MHTKL) and 121R63-1 (77-5 = THTTM), accounted for 79.46% of the population. Virulence on Lr19 was identified in 0.27% of the samples from Nepal only. The proportion of pathotype 121R60-1 (77-9 = MHTKL) increased to 57.55% during these years. Virulence was not observed on Lr9, Lr24, Lr25, Lr28, Lr32, Lr39, Lr45, and Lr47 in the population of the Indian subcontinent. Eighteen polymorphic simple sequence repeat (SSR) primer pairs tested on the isolates amplified 48 alleles with an average of 2.66 alleles per primer pair. Based on SSR genotyping, these pathotypes could be grouped into two clades with another two subclades each. Many of the Lr genes present in Indian wheat germplasm (Lr1, Lr3a, Lr10, Lr11, Lr14a, Lr15, Lr16, Lr17, Lr20, Lr23, and Lr26) were ineffective for a majority of pathotypes. Most of these varieties possessed a high degree of leaf rust resistance. The field resistance of wheat varieties could be attributed to the interaction of genes, unknown resistance, or adult plant resistance.

In vitro Assessment of Tris Egg Yolk and Soybean Lecithin Based Extenders for Cryopreservation of Crossbred Ram Semen.

BACKGROUND: The replacement of egg yolk with alternative plant-derived soybean lecithin is gaining interest in both animal and human sperm cryopreservation owing to biosecurity issues with egg yolk based extenders. OBJECTIVE: To evaluate the comparative effect of egg yolk and soyabean lecithin based extenders on the quality of cryopreserved crossbred ram semen. METHODS: Pooled ejaculates (total ejaculates = 36) were divided into two aliquots and extended with Tris egg yolk extender (Tris extender) and soybean lecithin based commercial extender (Ovixcell) RESULTS: Among the two extenders, Ovixcell showed better sperm quality both at the pre-freeze (Sperm motility) and post-thaw stages. Lower malondialdehyde (MDA) level (nmol/mL) was observed in Ovixcell as compared to Tris extender. Both sperm quality and MDA level decreased significantly (P < 0.05) from pre-freeze to post-thaw in both the extenders. CONCLUSION: The findings of the present study indicate that Ovixcell is a comparable alternative to Tris extender for the cryopreservation of crossbred ram semen.

Home video EEG telemetry.

Long-term electroencephalogram monitoring is often used to help distinguish epileptic from dissociative (non-epileptic) seizures. Home video telemetry now offers many of the benefits in diagnosis previously available only with inpatient video telemetry, which is usually regarded as the 'gold standard'. Here, we describe recent developments in home video telemetry and how we undertake this procedure in our unit.

Under-carboxylated osteocalcin regulates glucose and lipid metabolism during pregnancy and lactation in rats.

PURPOSE: Under-carboxylated osteocalcin (UcOC), a bone-released hormone is suggested to regulate energy metabolism. Pregnancy and lactation physiological conditions that require high levels of energy. The current study attempts to examine whether UcOC is involved in regulating energy metabolism during these conditions using adult Wistar rats. METHODS AND RESULTS: Insulin tolerance tests indicated insulin resistance during late pregnancy (day 19 of pregnancy; P19) and insulin sensitivity during early lactation (day 6 of lactation; L6). Gene expression analyses suggested that muscle glucose metabolism was downregulated during P19 and enhanced during L6. Concomitantly, circulatory UcOC levels were lower during pregnancy but higher during early lactation; the rise in UcOC levels was tightly linked to the lactation process. Altering endogenous UcOC levels pharmacologically with warfarin and alendronate in P19 and L6 rats changed whole-body insulin response and muscle glucose transporter (Glut4) expression. Glut4 expression can be increased by either UcOC or estrogen receptors (ERs), both of which act independent of each other. A high fat diet decreased UcOC levels and insulin sensitivity in lactating rats, suggesting that diet can compromise UcOC-established energy homeostasis. Gene expression of lipid metabolism markers and triglyceride levels suggested that UcOC suppression during early pregnancy is an essential step in maternal lipid storage. CONCLUSION: Taken together, we found that UcOC plays an important role in energy homeostasis via regulation of glucose and lipid metabolism during pregnancy and lactation.

Dentists' knowledge of chronic orofacial pain.

OBJECTIVE: Orofacial pain (OFP) is a unique group of dental conditions with focus on chronic nonodontogenic pain affecting mouth, jaws, and face. The aim of this study is to investigate the knowledge of dentists in Saudi Arabia toward OFP assessment. MATERIALS AND METHODS: An English language questionnaire containing 20 close-ended questions was used to capture data. The questionnaire included diagnostic criteria and clinical symptoms and signs of various OFP conditions. It was distributed to general dental practitioners (GDP) and dental specialists in four major provinces in Saudi Arabia. RESULTS: A total of 318 questionnaires were completed by 163 males and 155 females. Most participants were GDPs (193/318) and the remaining were specialists from different dental specialties. A majority of participants were not able to diagnose neuropathic OFP or neurovascular/vascular OFP conditions (33% and 28.6%, respectively). On the other hand, only 40.3% were confident enough to diagnose different types of temporomandibular disorders. The results also showed that graduates from non-Saudi programs had significantly higher self and knowledge assessment score (59.8% and 43.4%, respectively) compared with graduates from Saudi programs (39.9% and 22.6%, respectively). The dental specialists had higher self-assessment scores compared with GDPs (48% vs. 43.7%). Overall, there was a weak positive correlation between self-assessment and knowledge assessment (20.2%). CONCLUSION: This study demonstrates a higher OFP knowledge and confidence for dental specialists compared with GDPs. However, this difference does not necessarily translate into more competencies in clinical practice. Therefore, the implementation of OFP courses in dental schools' curricula may benefit future dentists and improve patients' care.

EFFECT OF EARLY SEXUAL DEBUT ON HIGH SCHOOL COMPLETION IN SOUTH AFRICA.

Early sexual debut is of major concern because it is a correlate for health and economic shocks experienced in adulthood. In South Africa, this concern has provided impetus for research directed at the HIV and AIDS epidemic, teenage pregnancy and the effect of adolescent sexual behaviour on persistence in school. Of interest to the present study is high school completion, which is a well-established empirical barometer of adult socioeconomic opportunities. Using data from the five waves of the Cape Area Panel Study (CAPS), this paper examines the association between sexual behaviours initiated in pre- and early adolescence and high school completion rates. The CAPS study is a longitudinal survey that was designed to investigate young people's (aged 14-22 years) educational attainment and sexual behaviours in Cape Town, South Africa. The sample was constituted from 3213 individuals who had initiated sex during their teenage years and the analysis was undertaken when the youngest cohort was aged 21, an age at which they should have completed high school if they were on time. Logistic regression models were fitted separately for males and females. Overall, the results reveal that early sexual debut is correlated with long-term negative educational outcomes. Individuals who experience early sexual debut are less likely to complete high school than their counterparts who make their sexual debut later on in life. This effect is worse for Africans, who also disproportionately have an earlier sexual debut than other race groups. Apart from race however, the findings also reinforce the effect of other demographic factors on high school completion, namely, place of residence and family socioeconomic status as measured by parental education and household income. Hence, early sexual debut adds another layer of inequality and worsens the plight of Africans, females, those living in rural areas and those who come from low-income families.

Potential risk factors for dental caries in Type 2 diabetic patients.

BACKGROUND: Diabetic patients are known to be at higher risk for dental caries. However, the role of potential risk factors such as blood glucose, salivary glucose and glycaemic control in the occurrence of dental caries in type 2 diabetes (T2D) is not clearly understood so far, and therefore, it was evaluated in this study. MATERIALS AND METHODS: This cross-sectional study was conducted on 100 T2D patients from Saudi Arabia. The caries risk assessment was evaluated using the guidelines of Caries Management by Risk Assessment (CAMBRA). Cariogenic bacteria load in saliva was determined by a chair-side test kit. The levels of fasting blood glucose (FBG), salivary glucose and HbA1c were analysed. RESULTS: Majority of the patients had dental caries (84%), exposed root surfaces (92%) and heavy plaque (73%), whereas 66% of patients suffered from xerostomia. The frequency of patients with high counts of Streptococcus mutans and Lactobacilli (LB) were 78% and 42%, respectively. There were significant associations between dental caries risk and FBG, HbA1c and salivary glucose. After categorizing the patients into 3 categories of glycaemic control, we observed a significant association between glycaemic control and dental caries risk. CONCLUSION: Type 2 diabetes patients are at high risk for dental caries, which is directly associated with FBG, HbA1c and salivary glucose. This is the first study measuring dental caries and its risk factors in T2D patients from Saudi Arabia.

Calvarial bone development and suture closure in Dicer-deficient mice.

OBJECTIVE: To evaluate whether lack of Dicer during calvaria development would lead to dysmorphology of calvaria and suture closure in mice. MATERIALS AND METHODS: A conditional Dicer deficient under Osx promoter mouse was employed in this study. The 4- and 10-week-old conditional Dicer-deficient mice control littermates and Osx-cre transgenic mice were studied for calvarial bone morphology and suture closure. Dry skull, microcomputed tomography (µCT), histological and gene expression studies were investigated to evaluate the effect of Dicer deficiency on calvarial bone morphology and their related genes during calvaria development. RESULTS: The results elucidated that complete suture closure was observed in 10-week-old conditional Dicer-deficient mice while incomplete closure suture was observed in age-matched Osx-cre control mice. The µCT and histological sections demonstrated complete fusion of posterior frontal suture and dysmorphic calvarial bones in Dicer deficient mice compared to the ones in their littermates and age-matched Osx-cre control mice. Gene expression study demonstrated significantly increased expression of suture and calvarial bone-related genes, that is Tgf-beta family, Bmp3, Msx2, Alx4, Runx2 and Osx in Dicer-deficient mice during suture closure time. CONCLUSIONS: The results suggest mature miRNAs are important for suture closure and calvarial morphology during calvaria development.

The impact of age on nodal metastases and survival in gastric cancer.

BACKGROUND: In gastric adenocarcinoma, the disparity in lymph node involvement between different age groups has not been thoroughly investigated. The objective of our study was to compare age-associated differences in adequate lymph node harvest and nodal involvement in gastric adenocarcinoma patients. METHODS: We analyzed data extracted from the Surveillance, Epidemiology and End Results database on 13,165 patients diagnosed with stage I-III gastric adenocarcinoma between 2004 and 2011. All patients underwent surgical resection. Statistical comparisons between various age groups were done using the chi-square test and Cox regression. RESULTS: Among 13,165 gastrectomy patients, proportion of patients that had >15 lymph nodes examined decreases significantly with increasing age (P < 0.0001). When adequately staged, older patients had a significantly lower proportion of node-positive tumors (P < 0.0001). Adequate nodal staging was also associated with improved 5-y disease-specific survival across all age groups. CONCLUSIONS: In gastric adenocarcinoma, older patients are less likely to be adequately staged. However, when adequately staged, they are less likely to have node-positive tumors. Adherence to national guidelines, regardless of age, is associated with improved survival outcomes and may alter multimodality management of gastric cancer in the elderly.

Familial effects on structural changes relevant to knee osteoarthritis: a prospective cohort study.

OBJECTIVE: Genetic factors play an important role in the pathogenesis of knee osteoarthritis (OA), but which knee structural changes mediate this is unclear. This study aimed to describe the differences in knee structural changes over 8-10 years between offspring having at least one parent with total knee replacement (TKR) for severe primary knee OA and controls with no family history of knee OA. DESIGN: 115 offspring (mean age 45 years) with a family history of TKR for severe knee OA were compared with 104 (mean age 46 years) controls. T1 or T2-weighted fat saturated magnetic resonance imaging (MRI) was performed respectively to evaluate knee cartilage defects, bone marrow lesions (BMLs), meniscal extrusion and tears at baseline and 10 years. Multivariate logistic regression model was used to adjust for potential confounders. RESULTS: Offspring had a greater increase in cartilage defect score (1.03 vs 0.52, P = 0.007) and meniscal extrusion score (0.28 vs 0.10, P = 0.027) over 10 years, and a greater increase in meniscal tear score (0.40 vs 0.10, P = 0.012) over 8 years in the medial but not the lateral tibiofemoral compartment. Changes in BMLs over 8-years were not different between the two groups. These associations were independent of potential confounders, and strengthened after further adjustment for each other. CONCLUSION: With the exception of BMLs, offspring with a family history of knee OA have a greater risk of increases in multiple knee structural abnormalities in the medial tibiofemoral compartment suggesting pleiotropic familial effects.

A family history of knee joint replacement increases the progression of knee radiographic osteoarthritis and medial tibial cartilage volume loss over 10 years.

OBJECTIVES: Osteoarthritis (OA) has a genetic component but it is uncertain if the offspring of those with knee OA are at a greater risk. The aim of this study was to describe radiographic OA (ROA) progression and cartilage loss over 10 years in a midlife cohort with some having a family history of OA and some community based controls. METHODS: 220 participants [mean-age 45 (26-61); 57% female] were studied at baseline and 10 years. Half were adult offspring of subjects who underwent knee replacement for OA and the remainder were randomly selected controls. Joint space narrowing (JSN) and osteophytes were assessed on radiographs and cartilage volume (tibial, femoral and patellar), cartilage defects, bone marrow lesions (BMLs) and meniscal tears were assessed on Magnetic resonance imaging (MRI). RESULTS: For ROA, there was a significant difference between offspring and controls in unadjusted analysis for change in total ROA, medial JSN, total medial, total lateral and total osteophyte scores. This difference persisted for medial JSN (difference in ratios = +1.93 (+1.04, +3.51)) only, after adjustment for confounders and baseline differences. In unadjusted analysis for cartilage loss, offspring lost more cartilage at the medial tibial (difference in means = -79.13 (-161.92, +3.71)) site only. This difference became of borderline significance after adjustment for baseline differences (P = 0.055). CONCLUSION: The offspring of subjects having a total knee replacement have a greater worsening of ROA (both JSN and osteophytes) and higher medial tibial cartilage volume loss over 10 years. Most of these changes are mediated by differences in baseline characteristics of offspring and controls except for increase in medial JSN.

Open pulled straw vitrification and slow freezing of sheep IVF embryos using different cryoprotectants.

The aim of the present study was to evaluate the post-thaw survival and hatching rates of sheep blastocysts using different cryoprotectants. In Experiment 1, Day 6 sheep embryos were cryopreserved by a slow freezing protocol using 10% ethylene glycol (EG), 10% dimethyl sulfoxide (DMSO) or a mixture of 5% EG and 5% DMSO. Hatching rates were higher in the 10% EG group than in the 10% DMSO or EG + DMSO groups (30% vs 18% and 20%, respectively). In Experiment 2, embryos were cryopreserved by open pulled straw (OPS) vitrification using either 33% EG, 33% DMSO or a mixture of 16.5% EG + 16.5% DMSO. Re-expansion and hatching rates in the EG + DMSO group (79.16% and 52.74%, respectively) were higher than those in the EG group (64.28% and 30.02%, respectively), whereas the outcomes for the DMSO group were the lowest (45.18% and 8.6%, respectively). In Experiment 3, embryos were cryopreserved by OPS vitrification using either 40% EG, 40% DMSO or a mixture of 20% EG + 20% DMSO. Re-expansion and hatching rates were highest in the EG group than in the EG + DMSO and DMSO groups (92.16% vs 76.30% and 55.84% re-expansion, respectively; and 65.78% vs 45.55% and 14.46% hatching, respectively). In conclusion, OPS vitrification was found to be more efficient for cryopreservation of in vitro-developed sheep embryos than traditional freezing.
