"Translation, cultural adaptation, and validation of perinatal grief scale in Urdu: Addressing a gap in the research of perinatal loss in Pakistan-Cross-sectional validation study".

Background and Aims: Perinatal grief have a significant influence on maternal mental health, hence appropriate tools for assessment are necessary. In this study, we translated and validated the Perinatal Grief Scale in Urdu (PGS-Urdu) for use in Pakistan, therefore filling the gap in validated tools. Methods: Data was collected from 165 women using consecutive sampling. Initially, "forward/backward" translation was used. For validity, content validity index and confirmatory factor analysis (CFA) were used respectively, and "Cronbach's-Alpha" for reliability. In the validity stage, items 8, 11, 23, and 32 of the original scale were eliminated based on feedback from the target groups and the expert panel. For data-analysis, SPSS 26 and Amos 26 were used. Results: In analyzing the "Confirmatory factor analysis", the "all-fitness indicators" validated the three-factor structure of 29-item main scale. Cronbach alpha value was 0.83 for the entire scale The CFA results showed that all fitness indicators, with the exception of four, had loadings greater than 0.20, supporting the main scale's three-factor structure. With a Cronbach's Alpha value of 0.83 for overall reliability, and varied from 0.81 to 0.87 for the PGS-U variables. the PGS-U exhibits an acceptable level of internal consistency. Conclusion: The PGS-U identifies women in perinatal grief for medical and social care. This research supports using the Urdu perinatal grief scale in obstetrics and bereavement counseling to reduce maternal mental health issues.

Social Support and Spousal Relationship Quality Improves Responsiveness among Anxious Mothers.

Maternal responsiveness, a mother's ability to consistently identify infant cues and then act on them, is critical for healthy child development. A woman's social support and spousal relationship may affect responsiveness to an infant, especially among mothers with anxiety. We assessed how social support and spousal relationship quality is associated with responsiveness among anxious mothers, and if postpartum depression (PPD) moderated these associations. Cross-sectional data were collected from 2019 to 2022 in a public hospital in Pakistan from 701 women at six-weeks postpartum. Eligible women had at least mild anxiety in early- to mid- pregnancy. Linear regression analyses assessed if spousal relationship quality and social support from family and friends were associated with maternal responsiveness, measured using the Maternal Infant Responsiveness Instrument. Interaction terms were used to examine if PPD moderated these associations. Spousal relationship quality (B = 2.49, 95% CI: 1.48, 3.50) and social support (B = 1.07, 95% CI: 0.31, 1.83) were positively related to maternal responsiveness to the infant. Emotional support from a spouse was positively associated with responsiveness (B = 1.08, 95% CI: 0.12, 2.03 depressed; B = 2.96, 95% CI: 1.34, 4.58 non-depressed), and conflict with the spouse was negatively associated with responsiveness (B=-1.02, 95% CI: -1.94, -0.09 depressed; B=-2.87, 95% CI: -4.36, -1.37 non-depressed). However, social support was related to responsiveness only in non-depressed women (B = 2.61, 95% CI: 1.14, 4.07). While spousal relationships and social support enhance maternal responsiveness, for depressed women, spousal relationships were particularly critical. In considering maternal-infant interventions to improve child development outcomes, our study indicates the importance of supportive relationships that foster effective responsiveness.

Family concerns and relationship problems in anxious pregnant women and their associations with postnatal functional disability in Pakistan.

OBJECTIVE: Expanding on existing research suggesting that strategies to reduce prenatal anxiety can decrease functional disability (e.g., difficulties in performing everyday activities and social participation), we examined if this effect varied by type of anxiety-producing problem (i.e., having family concerns and relationship problems versus other problems) reported during pregnancy. Further, we explored if perceived social support mediated this relationship. METHODS: We used longitudinal data on 310 anxious Pakistani women who received any psychosocial intervention sessions as part of a program that was based on Cognitive Behavioral Therapy. The Psychological Outcome Profiles (PSYCHLOPS) was used to assess whether women had 'family concerns and relationship problems' or 'other problems.' The WHO Disability Assessment Schedule 2.0 assessed functional disability at six-weeks after delivery. Lack of support was measured using a 12-item Multi-dimensional Scale of Perceived Social Support. We employed linear regression to examine associations between types of problems reported during pregnancy and postnatal functional disability. Causal mediation analysis was used to assess whether postnatal social support mediated this relationship. RESULTS: Of anxious pregnant women, 34% reported family concerns or relationship problems as primary problems in pregnancy. They were more likely to report higher functional disability at six-weeks after delivery than women who reported other problems (adjusted B = 2.40, 95% CI: 0.83-3.97). Lack of overall social support (Estimateindirect = 0.69, 95% CI: 0.04-1.38) and lack of support from friends (Estimateindirect = 0.62, 95% CI: 0.01-1.29) significantly mediated the relationship. CONCLUSIONS: Findings suggest that complementing pre- and post-natal care with support programs and services that address family concerns and relationship problems, as well as enhancing social support is important to functional disability.

Economic costs of perinatal depression and anxiety in a lower middle income country: Pakistan.

BACKGROUND: Women's mental health during the perinatal period is a major public health problem in Pakistan. Many challenges and competing priorities prevent progress to address the large treatment gap. Aim To quantify the long-term impacts of untreated perinatal depression and anxiety in economic terms, thus highlighting its overall burden based on country-specific evidence. METHODS: Cost estimates were generated for a hypothetical cohort of women giving birth in 2017, and their children. Women and children experiencing adverse events linked to perinatal mental health problems were modelled over 40 years. Costs assigned to adverse events included were those linked to losses in quantity and quality-of-life, productivity, and healthcare-related expenditure. Present values were derived using a discount rate of 3 %. Data were taken from published cohort studies, as well as from sources of population, economic and health indicators. RESULTS: The total costs were $16.5 billion for the cohort and $2680 per woman giving birth. The by far largest proportion referred to quality-of-life losses ($15.8 billion). Productivity losses and out-of-pocket expenditure made up only a small proportion of the costs, due to low wages and market prices. When the costs of maternal suicide were included, total costs increased to $16.6 billion. LIMITATIONS: Important evidence gaps prevented the inclusion of all cost consequences linked to perinatal mental health problems. CONCLUSIONS: Total national costs are much higher compared with those in other, higher middle-income countries, reflecting the excessive disease burden. This study is an important first step to inform resource allocations.

Pregnancy stressors and postpartum symptoms of depression and anxiety: the moderating role of a cognitive-behavioural therapy (CBT) intervention.

Background: Little is known about the association between stressors (especially positive stressors) during pregnancy and postpartum depression and anxiety. Aims: We investigated the association between positive and negative stress events during different stages of pregnancy and postpartum mental health outcomes among low-income pregnant women with symptoms of anxiety in Pakistan and evaluated whether an intervention based on cognitive-behavioural therapy (CBT) had a regulatory effect. Methods: Participants were 621 pregnant Pakistani women with mild anxiety. Using the Pregnancy Experience Scale-Brief Version, six scores were created to assess positive and negative stressors. We performed a multivariate linear regression to examine whether these six scores, measured both at baseline and in the third trimester, were associated with postpartum anxiety and depressive symptoms. The effect of the intervention on this relationship was examined by adding an interaction term to the regression model. Results: Hassles frequency measured in the third trimester was positively associated with depression (B=0.22, 95% confidence interval (CI): 0.09 to 0.36) and anxiety (B=0.19, 95% CI: 0.08to 0.30). At the same timepoint, uplifts intensity was negatively associated with symptoms of depression (B=-0.82, 95% CI: -1.46 to -0.18) and anxiety (B=-0.70, 95% CI: -1.25 to -0.15), whereas hassles intensity was positively related to symptoms of depression (B=1.02, 95% CI: 0.36 to 1.67) and anxiety (B=0.90, 95% CI: 0.34 to 1.47). The intensity ratio of hassles to uplifts reported in the third trimester was positively related to both depression (B=1.40, 95% CI: 0.59 to 2.20) and anxiety (B=1.26, 95% CI: 0.57 to 1.96). The intervention strengthened the overall positive effects of uplifts and the negative effects of hassles. Pregnancy experiences at baseline during early pregnancy to mid-pregnancy were not associated with mental health outcomes. Conclusions: Stressors in the third trimester but not earlier in pregnancy were associated with postpartum symptoms of anxiety and depression. The CBT intervention modified the association between pregnancy stressors and postpartum mental health outcomes. Programmes that promote positive experiences and reduce negative experiences, especially in late pregnancy, may mitigate postpartum mental health consequences. Trial registration number: NCT03880032.

Anxiety-focused cognitive behavioral therapy delivered by non-specialists to prevent postnatal depression: a randomized, phase 3 trial.

Anxiety experienced by women during pregnancy is highly prevalent, especially in resource-poor settings and strongly predicts postnatal common mental disorders (CMDs), anxiety and depression. We evaluated the effectiveness of an anxiety-focused early prenatal intervention on preventing postnatal CMDs. This study was a phase 3, two-arm, single-blind, randomized controlled trial conducted in Pakistan with women who were ≤22 weeks pregnant and had at least mild anxiety without clinical depression. Participants were randomized to the Happy Mother-Healthy Baby program, based on cognitive behavioral therapy, consisting of six one-on-one intervention sessions in pregnancy delivered by non-specialist providers, or to enhanced care alone. The primary outcome was major depression, generalized anxiety disorder or both at 6 weeks after delivery. Overall, 755 women completed postnatal assessments (380 (50.3%), intervention arm; 375 (49.7%) enhanced-care arm). The primary outcomes were met. Examined jointly, we found 81% reduced odds of having either a major depressive episode (MDE) or moderate-to-severe anxiety for women randomized to the intervention (adjusted odds ratio (aOR) = 0.19, 95% CI 0.14-0.28). Overall, 12% of women in the intervention group developed MDE at 6 weeks postpartum, versus 41% in the control group. We found reductions of 81% and 74% in the odds of postnatal MDE (aOR = 0.19, 95% CI 0.13-0.28) and of moderate-to-severe anxiety (aOR = 0.26, 95% CI 0.17-0.40), respectively. The Happy Mother-Healthy Baby program early prenatal intervention focusing on anxiety symptoms reduced postpartum CMDs. ClinicalTrials.gov identifier NCT03880032 .

Safety and outcomes of different endovascular treatment techniques for anterior circulation ischaemic stroke in the elderly: data from the Imperial College Thrombectomy Registry.

BACKGROUND: Although previous studies investigated the main predictors of outcomes after endovascular thrombectomy (EVT) in patients aged 80 years and older, less is known about the impact of the procedural features on outcomes in elderly patients. The aim of this study was to investigate the influence of EVT technical procedures on the main 3-month outcomes in a population of patients aged 80 years and older. METHODS: This observational, prospective, single-centre study included consecutive patients with acute LVO ischaemic stroke of the anterior circulation. The study outcomes were functional independence at 3 months after EVT (defined as a mRS score of 0-2), successful reperfusion (mTICI ≥ 2b), incidence of haeamorrhagic transformation, and 90-day all cause of mortality. RESULTS: Our cohort included 497 patients with acute ischaemic stroke due to LVO treated with EVT. Among them, 105 (21.1%) patients were aged ≥ 80 years. In the elderly group, multivariable regression analysis showed that thromboaspiration technique vs stent-retriever was the single independent predictor of favourable post-procedural TICI score (OR = 7.65, 95%CI = 2.22-26.32, p = 0.001). CONCLUSIONS: Our study suggests that EVT for LVO stroke in the elderly could be safe. The use of thromboaspiration was associated with positive reperfusion outcome in this population. Further studies in larger series are warranted to confirm the present results and to evaluate the safety and efficacy of EVT in the elderly and oldest adults.

Outcomes of mechanical thrombectomy in acute stroke patients with atrial fibrillation detected after stroke versus known atrial fibrillation.

We aim to compare the outcomes in patients with atrial fibrillation detected after stroke (AFDAS) and their counterparts with known AF (KAF) presenting with large vessel occlusion (LVO) treated with mechanical thrombectomy (MT). This observational, prospective study included consecutive patients with acute LVO ischemic stroke of the anterior circulation with AFDAS, KAF and without AF. The primary study outcome was functional independence at 90 days after stroke. The secondary study outcomes were variation of the NIHSS score at 24 h, rate of successful reperfusion, death at 90 days and rate of immediate complications post-procedure. Overall, our cohort included 518 patients with acute ischemic stroke and LVO treated with MT, with 289 (56.8%) without a diagnosis of AF; 107 (21%) with AFDAS; 122 (22.2%) with KAF. There was no significant difference in terms of functional independence at 90 days after stroke between the three groups. Regarding the secondary study outcome, the rate of symptomatic intracranial haemorrhage (sICH) and/or parenchymal hematoma (PH) were significantly higher in the group of patients without AF (respectively, P = 0.030 and < 0.010). Logistic regression analysis showed that the subtypes of AF were not statistically significantly associated with functional independence at 90 days after stroke and with the likelihood of any ICH. Our results suggest that the subtypes of AF are not associated with clinical and safety outcomes of MT in patients with acute stroke and LVO. Further studies are needed to confirm our findings.

Outcomes of mechanical thrombectomy in orally anticoagulated patients with anterior circulation large vessel occlusion: a propensity-matched analysis of the Imperial College Thrombectomy Registry.

BACKGROUND: Mechanical thrombectomy (MT) remains an effective treatment for patients with acute ischemic stroke receiving oral anticoagulation (OAC) and large vessel occlusion (LVO). However, to date, it remains unclear whether MT is safe in patients on treatment with OAC. AIMS: In our study, we performed a propensity-matched analysis to investigate the safety and efficacy of MT in patients with acute ischemic stroke receiving anticoagulants. A propensity score method was used to target the causal inference of the observational study design. METHODS: This observational, prospective, single-centre study included consecutive patients with acute LVO ischemic stroke of the anterior circulation. Demographic, neuro-imaging and clinical data were collected and compared according to the anticoagulation status at baseline, patients on OAC vs those not on OAC. The primary study outcomes were the occurrence of any intracerebral haemorrhage (ICH) and symptomatic ICH. The secondary study outcomes were functional independence at 90 days after stroke (defined as modified Rankin Scale (mRS) scores of 0 through 2), mortality at 3 months and successful reperfusion rate according to the modified treatment in cerebral infarction (mTICI) score. RESULTS: Overall, our cohort included 573 patients with acute ischemic stroke and LVO treated with MT. After propensity score matching, 495 patients were matched (99 OAC group vs 396 no OAC group). There were no differences in terms of clinical characteristics between the two groups, except for the rate of intravenous thrombolysis less frequently given in the OAC group. There was no significant difference in terms of the rate of any ICH and symptomatic ICH between the two groups. With regards to the secondary study outcome, there was no significant difference in terms of the rate of successful recanalization post-procedure and functional independence at 3 months between the two groups. Patients in the OAC group showed a reduced mortality rate at 90 days compared to the patients with no previous use of anticoagulation (20.2% vs 21.2%, p = 0.031). Logistic regression analysis did not reveal a statistically significant influence of the anticoagulation status on the likelihood of any ICH (OR = 0.95, 95% CI = 0.46-1.97, p = 0.900) and symptomatic ICH (OR = 4.87, 95% CI = 0.64-37.1, p = 0.127). Our analysis showed also that pre-admission anticoagulant use was not associated with functional independence at 90 days after stroke (OR = 0.76, 95% CI = 0.39-1.48, p = 0.422) and rate of successful reperfusion (OR = 0.81, 95% CI = 0.38-1.72, p = 0.582). CONCLUSION: According to our findings anticoagulation status at baseline did not raise any suggestion of safety and efficacy concerns when MT treatment is provided according to the standard guidelines. Confirmation of these results in larger controlled prospective cohorts is necessary.

Technology-assisted cognitive-behavior therapy delivered by peers versus standard cognitive behavior therapy delivered by community health workers for perinatal depression: study protocol of a cluster randomized controlled non-inferiority trial.

BACKGROUND: The lack of trained mental health professionals is a key barrier to scale-up of evidence-based psychological interventions in low and middle-income countries. We have developed an app that allows a peer with no prior experience of health-care delivery to deliver the cognitive therapy-based intervention for perinatal depression, the Thinking Healthy Programme (THP). This trial aims to assess the effectiveness and cost-effectiveness of this Technology-assisted peer-delivered THP versus standard face-to-face Thinking Healthy Programme delivered by trained health workers. METHODS: We will employ a non-inferiority stratified cluster randomized controlled trial design comparing the two formats of intervention delivery. A total of 980 women in the second or third trimester of pregnancy with a diagnosis of Major Depressive Episode, evaluated with the Structured Clinical Interview for DSM-V Disorders (SCID), will be recruited into the trial. The unit of randomization will be 70 village clusters randomly allocated in a 1:1 ratio to the intervention and control arms. The primary outcome is defined as remission from major depressive episode at 3 months postnatal measured with the SCID. Data will also be collected on symptoms of anxiety, disability, quality of life, service use and costs, and infant-related outcomes such as exclusive breastfeeding and immunization rates. Data will be collected on the primary outcome and selected secondary outcomes (depression and anxiety scores, exclusive breastfeeding) at 6 months postnatal to evaluate if the improvements are sustained in the longer-term. We are especially interested in sustained improvement (recovery) from major depressive episode. DISCUSSION: This trial will evaluate the effectiveness and cost-effectiveness of a technology-assisted peer-delivered cognitive behavioral therapy-based intervention in rural Pakistan. If shown to be effective, the novel delivery format could play a role in reducing the treatment gap for perinatal depression and other common mental disorders in LMIC. TRIAL REGISTRATION: The trial was registered at Clinicaltrials.gov (NCT05353491) on 29 April 2022.

Advances in mechanical thrombectomy for acute ischaemic stroke.

Mechanical thrombectomy is a ground breaking treatment for acute ischaemic stroke caused by occlusion of a large vessel. Its efficacy over intravenous thrombolysis has been proven in multiple trials with a lower number needed to treat than percutaneous coronary intervention for acute myocardial infarction. However, access to this key treatment modality remains limited with a considerable postcode lottery across the UK and many parts of the world. The evidence base for mechanical thrombectomy dates back to 2015. Since then, there have been important advances in establishing and widening the criteria for treatment. This narrative review aims to summarise the current evidence base and latest advances for physicians and academics with an interest in recanalisation treatments for acute ischaemic stroke.

Biological Mechanisms in Pregnant Women With Anxiety (Happy Mother-Healthy Baby Supplement Study): Protocol for a Longitudinal Mixed Methods Observational Study.

BACKGROUND: Anxiety and depression are common in the perinatal period and negatively affect the health of the mother and baby. Our group has developed "Happy Mother-Healthy Baby" (HMHB), a cognitive behavioral therapy-based psychosocial intervention to address risk factors specific to anxiety during pregnancy in low- and middle-income countries (LMICs). OBJECTIVE: The purpose of this study is to examine biological mechanisms that may be linked to perinatal anxiety in conjunction with a randomized controlled trial of HMHB in Pakistan. METHODS: We are recruiting 120 pregnant women from the Holy Family Hospital, a public facility in Rawalpindi, Pakistan. Participants are assessed for at least mild anxiety symptoms using the Hospital Anxiety and Depression Scale (ie, a score ≥8 on the anxiety scale is necessary for inclusion in the anxiety groups and <8 for inclusion in the healthy control group). Women who meet the criteria for an anxiety group are randomized into either the HMHB intervention group or an enhanced usual care (EUC) control group. Participants receive HMHB or EUC throughout pregnancy and undergo blood draws at 4 time points (baseline, second trimester, third trimester, and 6 weeks post partum). We will assess peripheral cytokine concentrations using a multiplex assay and hormone concentrations using gas chromatography and mass spectrometry. The statistical analysis will use generalized linear models and mixed effects models to assess the relationships across time among anxiety, immune dysregulation, and hormone levels, and to assess whether these biological factors mediate the relationship between anxiety and birth and child development outcomes. RESULTS: Recruitment started on October 20, 2020, and data collection was completed on August 31, 2022. The start date for recruitment for this biological supplement study was delayed by approximately half a year due to the COVID-19 pandemic. The trial was registered at ClinicalTrials.gov (NCT03880032) on September 22, 2020. The last blood samples were shipped to the United States on September 24, 2022, where they will be processed for analysis. CONCLUSIONS: This study is an important addition to the HMHB randomized controlled trial of an intervention for antenatal anxiety. The intervention itself makes use of nonspecialist providers and, if effective, will represent an important new tool for the treatment of antenatal anxiety in LMICs. Our biological substudy is one of the first attempts to link biological mechanisms to antenatal anxiety in an LMIC in the context of a psychosocial intervention, and our findings have the potential to significantly advance our knowledge of the biological pathways of perinatal mental illness and treatment efficacy.

Endovascular Thrombectomy with or without Intravenous Thrombolysis for Anterior Circulation Large Vessel Occlusion in the Imperial College London Thrombectomy Registry.

Background and purpose. Mechanical thrombectomy (MT) is the standard of care for eligible patients with a large vessel occlusion (LVO) acute ischemic stroke. Among patients undergoing MT there has been uncertainty regarding the role of intravenous thrombolysis (IVT) and previous trials have yielded conflicting results regarding clinical outcomes. We aim to investigate clinical, reperfusion outcomes and safety of MT with or without IVT for ischemic stroke due to anterior circulation LVO. Materials and Methods. This observational, prospective, single-centre study included consecutive patients with acute LVO ischemic stroke of the anterior circulation. The primary outcomes were the rate of in-hospital mortality, symptomatic intracranial haemorrhage and functional independence (mRS 0-2 at 90 days). Results. We enrolled a total of 577 consecutive patients: 161 (27.9%) were treated with MT alone while 416 (72.1%) underwent IVT and MT. Patients with MT who were treated with IVT had lower rates of in-hospital mortality (p = 0.037), higher TICI reperfusion grades (p = 0.007), similar rates of symptomatic intracranial haemorrhage (p = 0.317) and a higher percentage of functional independence mRS (0-2) at 90 days (p = 0.022). Bridging IVT with MT compared to MT alone was independently associated with a favorable post-intervention TICI score (>2b) (OR, 1.716; 95% CI, 1.076-2.735, p = 0.023). Conclusions. Our findings suggest that combined treatment with MT and IVT is safe and results in increased reperfusion rates as compared to MT alone.

Perceived Social Support and Women's Empowerment and Their Associations with Pregnancy Experiences in Anxious Women: A Study from Urban Pakistan.

OBJECTIVES: Psychological distress in pregnancy is associated with adverse postnatal outcomes. We aimed to identify how social support and women's empowerment are associated with pregnancy-specific daily experiences among women suffering antenatal anxiety in Pakistan. METHODS: Data were collected as part of a randomized controlled trial of a psychosocial intervention for antenatal anxiety in a tertiary hospital in Pakistan. We included 594 women in early pregnancy (≤ 22 weeks) who endorsed mild to severe anxiety symptoms. Generalized linear regression models were used to analyze the associations of perceived social support and women's empowerment in relation to pregnancy-specific daily hassles and uplifts using a culturally adapted and psychometrically validated version of the Pregnancy Experience Scale-Brief. RESULTS: High social support was positively associated with frequency and intensity of positive pregnancy-specific experiences (B = 0.39, 95% CI 0.23-0.54 uplifts frequency; and B = 0.17, 95% CI 0.12-0.22 uplifts intensity), and was inversely associated with frequency of negative pregnancy-specific experiences (B = - 0.44, 95% CI - 0.66, - 0.22). Women's household empowerment was associated with greater uplifts frequency and intensity (B = 0.55, 95% CI 0.20-0.90 frequency; and B = 0.28, 95% CI 0.17-0.40 intensity). High social support and household empowerment were inversely related to PES hassle-to-uplift ratio scores. CONCLUSIONS FOR PRACTICE: Greater social support and household empowerment were associated with positive pregnancy-specific experiences in the context of antenatal anxiety in Pakistan.

Non-specialist-delivered psychosocial intervention for prenatal anxiety in a tertiary care setting in Pakistan: a qualitative process evaluation.

OBJECTIVES: A manualised cognitive-behavioural therapy-based psychosocial intervention for prenatal anxiety called Happy Mother Healthy Baby is being tested for its effectiveness through a randomised control trial in Pakistan. The aim of this study was to evaluate the intervention delivery process and the research process. DESIGN: Qualitative methods were used to explore in depth the intervention delivery and research process. SETTING: This process evaluation was embedded within a randomised control trial conducted in a tertiary care facility in Rawalpindi, Pakistan. PARTICIPANTS: Data were collected through in-depth interviews (n=35) with the trial participants and focus group discussions (n=3) with the research staff. Transcripts were analysed using a Framework Analysis. RESULTS: The evaluation of the intervention delivery process indicated that it can be effectively delivered by non-specialist providers trained and supervised by a specialist. The intervention was perceived to be culturally acceptable and appropriately addressing problems related to prenatal anxiety. Lack of awareness of 'talking' therapies and poor family support were potential barriers to participant engagement. The evaluation of the research process highlighted that culturally appropriate consent procedures facilitated recruitment of participants, while incentivisation and family involvement facilitated sustained engagement and retention. Lack of women's empowerment and mental health stigma were potential barriers to implementation of the programme. CONCLUSION: We conclude that non-specialists can feasibly deliver an evidence-based intervention integrated into routine antenatal care in a tertiary hospital. Non-specialist providers are likely to be more cost effective and less stigmatising. Inclusion of family is key for participant recruitment, retention and engagement with the intervention.

Assessment of Geographical Distribution of Emerging Zoonotic Toxoplasma gondii Infection in Women Patients Using Geographical Information System (GIS) in Various Regions of Khyber Pakhtunkhwa (KP) Province, Pakistan.

Toxoplasmosis is a zoonotic parasitic disease caused by T. gondii, an obligate intracellular apcomplexan zoonotic parasite that is geographically worldwide in distribution. The parasite infects humans and all warm-blooded animals and is highly prevalent in various geographical regions of the world, including Pakistan. The current study addressee prevalence of Toxoplasma infection in women in various geographical regions, mapping of endemic division and t district of Khyber Pakhtunkhwa province through geographical information system (GIS) in order to locate endemic regions, monitor seasonal and annual increase in prevalence of infection in women patients. Setting: Tertiary hospitals and basic health care centers located in 7 divisions and 24 districts of Khyber Pakhtunkhwa (KP) province of Pakistan. During the current study, 3586 women patients from 7 divisions and 24 districts were clinically examined and screened for prevalence of T. gondii infection. Participants were screened for Toxoplasma infection using ICT and latex agglutination test (LAT) as initial screening assay, while iELISA (IgM, IgG) was used as confirmatory assay. Mapping of the studied region was developed by using ArcGIS 10.5. Spatial analyst tools were applied by using Kriging/Co-kriging techniques, followed by IDW (Inverse Distance Weight) techniques. Overall prevalence of T. gondii infection was found in 881 (24.56%) patients. A significant (<0.05) variation was found in prevalence of infection in different divisions and districts of the province. Prevalence of infection was significantly (<0.05) high 129 (30.07%) in Kohat Division, followed by 177 (29.06%), 80 (27.87%), 287 (26.72%), 81 (21.21%), 47 (21.07%), and 80 (13.71%) cases in Hazara Division, D.I Khan Division, Malakand Division, Mardan Division, Bannu Division, and Peshawar Division. Among various districts, a significant variation (<0.05) was found in prevalence of infection. Prevalence of infection was significantly (<0.05) high 49 (44.95%) in district Karak, while low (16 (10.81%) in district Nowshera. No significant (>0.05) seasonal and annual variation was found in prevalence of Toxoplasma infection. LAT, ICT and ELISA assays were evaluated for prevalence of infection, which significantly (<0.05) detected T. gondii antibodies. LAT, ICT and ELISA assays significantly (<0.05) detected infection, while no significant (>0.05) difference was found between positivity of LAT and ICT assays. A significant difference (<0.05) was found in positivity of Toxoplasma-specific (IgM), (IgG) and (IgM, IgG) immunoglobulin by ICT and ELISA assay. The current study provides comprehensive information about geographical distribution, seasonal and annual variation of Toxoplasmosis infection in various regions of Khyber Pakhtunkhwa province of Pakistan. Infection of T. gondii in women shows an alarming situation of disease transmission from infected animals in the studied region, which is not only a serious and potential threat for adverse pregnancy outcomes, but also cause socioeconomic burden and challenges for various public and animal health organizations in Pakistan and across the country.

Mechanical thrombectomy in acute basilar artery stroke: a systematic review and Meta-analysis of randomized controlled trials.

BACKGROUND: The evidence for mechanical thrombectomy in acute basilar artery occlusion has until now remained inconclusive with basilar artery strokes associated with high rates of death and disability. This systematic review and meta-analysis will summarize the available evidence for the effectiveness of mechanical thrombectomy in acute basilar artery occlusion compared to best medical therapy. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials using Embase, Medline and the Cochrane Central Register of Controlled Trials (CENTRAL). We calculated risk ratios (RRs) and 95% confidence intervals (CIs) to summarize the effect estimates for each outcome. RESULTS: We performed a random effects (Mantel-Haenszel) meta-analysis of the four included randomized controlled trials comprising a total of 988 participants. We found a statistically significant improvement in the rates of those with a good functional outcome (mRS 0-3, RR 1.54, 1.16-2.06, p = 0.003) and functional independence (mRS 0-2, RR 1.69, 1.05-2.71, p = 0.03) in those who were treated with thrombectomy when compared to best medical therapy alone. Thrombectomy was associated with a higher level of sICH (RR 7.12, 2.16-23.54, p = 0.001) but this was not reflected in a higher mortality rate, conversely the mortality rate was significantly lower in the intervention group (RR 0.76, 0.65-0.89, p = 0.0004). CONCLUSIONS: Our meta-analysis of the recently presented randomized controlled studies is the first to confirm the disability and mortality benefit of mechanical thrombectomy in basilar artery stroke.

'Those whom I have to talk to, I can't talk to': Perceived social isolation in the context of anxiety symptoms among pregnant women in Pakistan.

Anxiety during pregnancy is highly prevalent in low- and middle-income countries. The relative importance of different sources and types of perceived support in the Pakistani context is unknown. We explored social support during pregnancy and the role of social isolation in Pakistani women's experiences of antenatal anxiety. We conducted semi-structured interviews with 19 pregnant women with symptoms of anxiety and 10 female healthcare providers at a public urban hospital. We used inductive and deductive thematic coding to analyse the data. Many pregnant women reported feelings of physical and social isolation, even when living in joint families with larger social networks. Often fearing censure by their in-laws and peers for sharing or seeking help with pregnancy-related anxieties, women reported relying on husbands or natal family members. Normative expectations around pregnancy such as male gender preference, perceived immutability of wives' domestic responsibilities and expectations of accompanied travel by women may serve as sources of disconnectedness in the antenatal period. Providers viewed social isolation and deficits in social support during pregnancy as contributing to worse anxiety symptoms, reduced access to care and poorer health behaviours. One limitation is that the hospital setting for this study may have resulted in underreporting of abuse or neglect and limited inclusion of pregnant women who do not utilise facility-based antenatal care. In conclusion, husbands and natal families were key in reducing social isolation in pregnancy and mitigating anxiety, while in-laws did not always confer support. Targeted strategies should enhance existing support and strengthen in-law family relationships in pregnancy.

Predicting Remission among Perinatal Women with Depression in Rural Pakistan: A Prognostic Model for Task-Shared Interventions in Primary Care Settings.

Perinatal depression is highly prevalent in low- and middle-income countries (LMICs) and is associated with adverse maternal and child health consequences. Task-shared psychological and psychosocial interventions for perinatal depression have demonstrated clinical and cost-effectiveness when delivered on a large scale. However, task-sharing approaches, especially in LMICs, require an effective mechanism, whereby clients who are not likely to benefit from such interventions are identified from the outset so that they can benefit from higher intensity treatments. Such a stratified approach can ensure that limited resources are utilized appropriately and effectively. The use of standardized and easy-to-implement algorithmic devices (e.g., nomograms) could help with such targeted dissemination of interventions. The present investigation posits a prognostic model and a nomogram to predict the prognosis of perinatal depression among women in rural Pakistan. The nomogram was developed to deliver stratified model of care in primary care settings by identifying those women who respond well to a non-specialist delivered intervention and those requiring specialist care. This secondary analysis utilized data from 903 pregnant women with depression who participated in a cluster randomized, controlled trial that tested the effectiveness of the Thinking Healthy Program in rural Rawalpindi, Pakistan. The participants were recruited from 40 union councils in two sub-districts of Rawalpindi and randomly assigned to intervention and enhanced usual care. Sixteen sessions of the THP intervention were delivered by trained community health workers to women with depression over pregnancy and the postnatal period. A trained assessment team used the Structured Clinical Interview for DSM-IV current major depressive episode module to diagnose major depressive disorder at baseline and post-intervention. The intervention received by the participants emerged as the most significant predictor in the prognostic model. Among clinical factors, baseline severity of core-emotional symptoms emerged as an essential predictor, followed by atypical symptoms and insomnia. Higher severity of these symptoms was associated with a poorer prognosis. Other important predictors of a favorable prognosis included support from one's mother or mother-in-law, financial empowerment, higher socioeconomic class, and living in a joint family system. This prognostic model yielded acceptable discrimination (c-statistic = 0.75) and calibration to aid in personalized delivery of the intervention.
