Abstract
This present research aimed to investigate the novel applications of synthesized La doped CuFe2O4 nanomaterial (LCF NMs) using renewable bio-fuel (Aegle Marmelos extract) by combustion process. The sensor applications were accomplished by modified electrode using LCF NMs with graphite powder and examined its excellent sensing action towards heavy metal (Lead content) and drug chemical (Paracetamol) substances. The thermodynamics of redox potential and super-capacitor behavior of LCF NMs were investigated through Cyclic Voltametric (CV) and Electrochemical Impedance Spectral (EIS) methods under specific conditions at scan rate of 1 to 5 mV/s. The heterogeneous photo-catalytic process of prepared NMs on Fast orange Red (FOR) dye-decolouration was investigated and noted its excellent degradation (91.7%) at 90 min using 20 ppm of dye solution and 40 mg of synthesized samples under Sun-light irradiation. Further, the antibacterial activity of synthesized NMs is investigated against various strains of gram positive (Bacillus subtillis) and gram negative bacteria (Pseudomonas aeruginosa), which confirms that the LCF NMs have higher activity towards gram positive bacteria with an average inhibition zone of 19 mm. This synthesized LCF NMs is a multi-functional material with stable and eco-friendly materials.

Abstract
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.

Abstract
OBJECTIVE To assess the effectiveness of prenatal and postnatal home visits (HVs) and women group meetings (WGMs) by paramedical professionals to improve maternal and child health outcomes in low- and middle-income countries (LMICs). STUDY DESIGN Systematic review and meta-analysis. METHODS We conducted a systematic review of trials published till December 2020, as per registered protocol in The International Prospective Register of Systematic Reviews (PROSPERO) (CRD42018091968). Outcomes were neonatal mortality rate (NMR), maternal mortality ratio (MMR), the incidence of low birth weight, and still birth rate (SBR). The Cochrane Pregnancy and Childbirth Group's Trials Register, Cochrane Central Register of Controlled Trials, PubMed, and Excerpta Medica Database (EMBASE) were searched. Pooled results were estimated using random-effects meta-analysis in RevMan version 5.2. RESULTS Twenty-five trials met the inclusion criteria. HVs were the key intervention in 12, WGMs in 11, and both interventions in 2 trials. The pooled estimates have shown that NMR was significantly reduced by HVs (OR 0.77, confidence interval [CI]: 0.67-0.90, P = 0.0007, I2 = 77%) and WGMs (OR 0.76, CI: 0.65-0.90, P = 0.001, I2 = 71%). SBR was significantly reduced by HVs (OR 0.77, CI: 0.70-0.85; P < 0.001, I2 = 0%). Subgroup analysis of studies in which more than 10% of pregnant women participated in the WGMs showed significant reduction in NMR (OR 0.67, CI 0.58-0.77, P = 0.00001, I2 = 31%) and MMR (OR 0.55, CI 0.36-0.84, P = 0.005, I2 = 27%). Two studies reported improvement in birth weight by HVs. CONCLUSIONS HVs and WGMs (with >10% pregnant women) by paramedical professionals are effective strategies in reducing the NMR and MMR in LMICs. HVs were also effective in reducing SBR.

Abstract
The accessory glands of male moths secrete several proteins, which are known to affect post-mating behaviour in females such as calling, reduction in receptivity, rate of egg maturation and laying, sperm maintenance and release and formation of mating plug. Helicoverpa armigera (Hübner) is a polyphagous pest of numerous crops and it is widely distributed on the Indian subcontinent where it causes severe economic losses. In the present study, receptivity- and calling-inhibiting substance (RCIS), a peptide secreted from the accessory glands of male H. armigera, was sequenced, cloned and expressed in a prokaryote, Escherichia coli. RCIS is a peptide comprising 58 amino acids and had a theoretical molecular weight of 6.03 kDa. It showed 64% similarity with pheromonostatic peptide 1, identified in Helicoverpa zea (Kingan et al., 1995) but differed regarding deletion of four and one amino acids at positions 14-17 and 44, respectively, and insertion of one and five amino acids at position 38 and the terminal position of RCIS, respectively. H. armigera females injected with recombinant RCIS showed reduced receptivity and calling behaviour (in 70-80% of the treated individuals), and mating frequencies decreased by 80%. Recombinant RCIS may be employed to artificially induce non-receptivity in virgin females in order to prevent reproduction.

Abstract
BackgroundIt is becoming well established that CBT is both effective and cost efficient in the treatment of positive and negative symptoms of schizophrenia. However, there is a need to adapt CBT to the cultural, linguistic, and socioeconomic context of diverse cultural groups. We aimed to establish the feasibility of culturally adaptive cognitive behavior therapy for treatment of psychosis in a low-income country.MethodsThis is a rater-blind, randomized, controlled trial of the use of CBT in patients with psychosis from a low-income country. Patients with a DSM-IV diagnosis of schizophreniform disorder were assessed using Positive and Negative Syndrome Scale for Schizophrenia (PANSS), PSYRATS (Psychotic Symptom Rating Scales), and the Insight Scale. Participants were randomized into the intervention group (n = 18) and TAU group (n = 18). The intervention group received 12 weekly sessions of culturally adapted CBT for psychosis (CaCBTp).ResultsThere were no significant differences between the two groups at baseline. At three months follow-up, there was a statistically significant improvement in the CaCBTp group on PANSS general Psychopathology subscale, PANSS overall score and Insight scale, as compared to the TAU group. The CaCBTp group had lower scores on PANSS positive, PANSS negative sub-scales, and the two subscales of Psychotic Symptom Rating Scale, but differences were not statistically significant.ConclusionCulturally adapted CBT added to pharmacological treatment as usual was acceptable to patients and was helpful in reduction of severity of psychotic symptoms. Adjunctive culturally adapted CBT should be further investigated in this population.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION Non-diagnostic results of fine needle aspiration biopsy (FNAB) remain an important limitation of this technqiue. The aim of our study was to evaluate the results of core needle biopsy (CNB) of thyroid nodules and its effectiveness in non-diagnostic FNAB cases. METHODS CNBs were performed in 1,000 patients (154 male, 846 female; mean age: 50.2 years, range: 18-86 years) with a spring loaded 20G needle. Of these, 143 had initially had FNABs that were insufficient for evaluation. The CNB reports were reviewed. Patients with suspicious or malignant CNB results underwent total thyroidectomy. RESULTS When considering all 1,000 CNBs, the non-diagnostic rate was 1.5% (15/1,000). However, when the first 100 cases were eliminated as a learning curve, this reduced to 0.9% (8/900). Of the 143 cases with initial FNABs that were non-diagnostic, 0.7% (1/143) were also non-diagnostic on CNB. Twelve patients underwent surgery because of malignant CNB reports and all of these cases were confirmed as malignant by the postoperative pathology specimen results (100% accuracy). There were no major complications although three self-limiting minor complications were observed. CONCLUSIONS CNB is a safe and accurate method. It is more diagnostic than FNAB for nodular thyroid disease.

Abstract
Background Data on the social determinants of health can help primary care practices target improvement efforts, yet relevant data are rarely available. Our family practice located in Toronto, Ontario routinely collects patient-level sociodemographic data via a pilot-tested survey developed by a multi-organizational steering committee. We sought to use these data to assess the relationship between the social determinants and colorectal, cervical and breast cancer screening, and to describe the opportunities and challenges of using data on social determinants from a self-administered patient survey. Methods Patients of the family practice eligible for at least one of the three cancer screening types, based on age and screening guidelines as of June 30, 2015 and who had answered at least one question on a socio-demographic survey were included in the study. We linked self-reported data from the sociodemographic survey conducted in the waiting room with patients’ electronic medical record data and cancer screening records. We created an individual-level income variable (low-income cut-off) that defined a poverty threshold and took household size into account. The sociodemographic characteristics of patients who were overdue for screening were compared to those who were up-to-date for screening for each cancer type using chi-squared tests. Results We analysed data for 5766 patients for whom we had survey data. Survey participants had significantly higher screening rates (72.9, 78.7, 74.4% for colorectal, cervical and breast cancer screening respectively) than the 13, 036 patients for whom we did not have survey data (59.2, 65.3, 58.9% respectively). Foreign-born patients were significantly more likely to be up-to-date on colorectal screening than their Canadian-born peers but showed no significant differences in breast or cervical cancer screening. We found a significant association between the low-income cut-off variable and cancer screening; neighbourhood income quintile was not significantly associated with cancer screening. Housing status was also significantly associated with colorectal, cervical and breast cancer screening. There was a large amount of missing data for the low-income cut-off variable, approximately 25% across the three cohorts. Conclusion While we were able to show that neighbourhood income might under-estimate income-related disparities in screening, individual-level income was also the most challenging variable to collect. Future work in this area should target the income disparity in cancer screening and simultaneously explore how best to collect measures of poverty.

Abstract
A 38-year-old female patient experienced groin pain; ultrasound imaging revealed a dermoid cystic mass in the right ovary and a cystectomy was then performed. Unusually, a mature cerebellum is found in the cyst wall. The pathological diagnosis was 'mature cystic teratoma with well-differentiated cerebral and cerebellar tissue'. Glial tissue is a common neural component of teratomas, but a cerebellum is extremely rare in mature ovarian cystic teratomas. The authors report the case because of its rare component; they acknowledge that a cystic teratoma is the most common neoplasm of ovarian germ cells.

Abstract
BackgroundCognitive impairments are well established findings in schizophrenia and are associated with significant impairment of social functioning. Episodic memory, working memory and executive function test scores are typically 1 standard deviation below healthy controls. There are reports suggesting the presence of neurocognitive deficits prior to illness onset, opening the possibility of using cognitive profiles as disease markers. Interest in exploring cognitive functioning in early stages schizophrenia has continued to grow, as earlier treatments could possibly lead to improved outcomes.MethodsThis is a cross-sectional assessment of cognitive profiles in patients with early psychosis. A total of 51 patients suffering from psychosis in the age group of 18–65 years were recruited and matched with 51 healthy controls. A wide range of neurocognitive domains were assessed using standardised neuropsychological tests.ResultsThere was evidence of statistically significant impairments in cognitive functioning across a broad range of cognitive domains in early-psychosis patients, as compared to healthy controls. More pronounced deficits were seen in executive function tests.ConclusionsTo our knowledge, this is the first study to report cognitive deficits across a range of domains in patients with first episode psychosis from a low-income country. This study found deficits across multiple domains, including language, memory, attention, executive function, and visuospatial function in patients with early psychosis. Evidence of neuropsychological deficits in the early course of the disease may highlight crucial therapeutic windows for both pharmacological treatments and cognitive rehabilitation. This may improve functional outcomes in this patient group in the longer term.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionPostnatal depression is known to cause disability and suffering in women and negative consequences both for their infants and their families, with huge costs globally. Several studies from low and middle income countries (LAMIC) have demonstrated that effectively delivered psychological interventions are cost effective for improving maternal and child health, but access to these interventions is limited in both the low and high income countries.ObjectiveThe objective of the study is to develop and test a mobile phone-based intervention (TechMotherCare), which will include components of cognitive behavioural therapy (CBT) and child development related psychoeducation.AimThe aim of the study is to examine the feasibility and acceptability of the TechMotherCare intervention.MethodsA total of 36 participants will be recruited from health centers in Karachi, Pakistan for this 2-arm randomized pilot study. The TechMotherCare App intervention will be based on principles of CBT and learning-through-play (LTP) a parenting intervention and will assess the real-time depressive symptoms of participants and respond, using intelligent real time therapy (iRTT) dependent on symptoms reported by participants.ResultsOutcome assessments will be completed after 3 months (end of intervention). In-depth qualitative interviews will also be conducted with participants pre- and post-intervention. The trial is ongoing and we will present both the qualitative and quantitative results.ConclusionsThe results of this pilot trial will inform the design of a larger randomised controlled trial using a mobile based technology platform to address the huge treatment gap in LAMICs.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Gastric xanthoma is uncommon lesion with a variably reported frequency. Hyperplastic polyps are commonest epithelial polyps in stomach. A rare case of simultaneous presence of xanthoma with hyperplastic polyp is reported. A 70-year-old female presented with dyspepsia and heartburn. Upper gastro-intestinal endoscopy showed multiple sessile small whitish polyps in stomach. Histopathological examination of the polyps-showed features of xanthoma with hyperplastic polyp in the mucosa with areas of intestinal metaplasia and occasional H pylori. There was no evidence of malignancy in the present case.

Abstract
BACKGROUND The Quality and Outcomes Framework, a financial incentive scheme for general practitioners in the UK, seems to have improved the quality of primary care and reduced inequalities in primary care delivery. It remains unclear, however, whether higher-quality primary care improves health outcomes or reduces health inequalities. METHODS We conducted a cross-sectional study examining the association between quality of cardiovascular care and coronary heart disease (CHD) outcomes in 1531 general practices in London. We calculated CHD quality achievement scores (ranging from 0 to 100) for each practice using the 2006-2007 data from the Quality and Outcomes Framework. We used weighted linear regression models to assess the practice-level association between the CHD quality score and CHD admissions and deaths. FINDINGS Overall, practices with higher CHD quality achievement scores had better CHD outcomes. Each one point increase in the CHD quality achievement score was associated with 4.28 (95% CI 1.19 to 7.38; p=0.007) fewer admissions per 100,000 for practices serving highly deprived populations and 2.11 (95% CI 0.68 to 3.55; p=0.004) fewer admissions per 100 000 for practices serving populations of average deprivation. There was no association between the CHD quality achievement score and the CHD admissions for practices serving affluent populations (p=0.906). We observed a similar deprivation-dependent gradient between quality achievement and CHD deaths. INTERPRETATION High-quality primary care is associated with improved health outcomes. This association is strongest in deprived areas, suggesting that high-quality primary care may play an important role in reducing health inequalities.
