    Labor’s health and safety (H&S) is a matter of concern for all industries. Occurrence of accidents in industries is becoming a common issue. Both white collar and blue-collar workers are not shielded from materials that damage their health. This study identifies the critical factors affecting labor’s H&S in Hyderabad, Pakistan industries. The awareness of labor regarding prevention and consequences that affect workers’ H&S is also a matter of interest of this research. The severity of factors was determined through questionnaire survey from experts, H&S supervisors and managerial staff of industries. For the descriptive analysis the software SPPS 24.0 was used. This research also includes interviews form industry laborers about awareness regarding H&S critical factors. The results show that, Improper PPE use, operating machines that are poorly maintained, long term exposure to high intensity noise, working extended and irregular hours and lack of knowledge of working instruments are the critical causes of accidents. Also 60.9%, 73.9%, 69.6%, 78.3% and 89% of workers are not aware about these causes and their consequences. Thus, this research is a road map for industrial employers, law makers, local, provisional and federal Government of Pakistan in order to help minimizing the workplace accidents and the providing of safe and secure working environment for laborers

    Papaya mealybug is notorious pest of papaya & other horticultural crops. Keeping in mind the role of parasitoids and predators in pest management, an exploratory study was conducted on the availability of natural enemies of recently introduced papaya mealybug, Paracoccus marginatus in Selangor and Negri Sembilan states of Peninsular Malaysia. Results revealed the presence of two predators (Cryptolaemus montrouzieri and Apertochrysa sp.), one primary parasitoid (Acerophagus papayae) and three hyperparasitoids (Chartocerus sp., Marietta leopardina and Cheiloneurus sp.). Among all natural enemies recorded, populations of C. montrouzieri and A. papayae were frequently recorded from all sampled locations of the two states. Accordingly, these two species should be exploited for their potential to manage populations of P. marginatus below threshold levels

    Time overrun is a major issue in construction projects. Its causes vary, depending upon the nature and size of the project. Developing countries are more susceptible to this problem due to limited resources and lack of managerial skills. This paper focuses on the identification and classification of time overrun factors in public sector projects in Pakistan. Data was collected by the use of a questionnaire given to different professionals in the construction field. Average index (AI) was used to determine each factor’s relative importance. Results indicate that financial difficulties faced by constructor, inadequate planning and scheduling, financial difficulties faced by client, delays in payment by the client, delays in decision making by the client, design mistakes, frequent design changes, material shortage, incompetent sub-constructor assigned by the constructor, poor site management and supervision and inadequate constructor’s experience are the most significant factors of time overrun in public sector construction projects in Pakistan. This study aims to be useful in addressing the issue of time overrun in the construction industry

    Potent blockchain-rnabled socket RPC Internet of Healthcare Things (IoHT) framework for medical enterprises

    Present-day intelligent healthcare applications offer digital healthcare services to users in a distributed manner. The Internet of Healthcare Things (IoHT) is the mechanism of the Internet of Things (IoT) found in different healthcare applications, with devices that are attached to external fog cloud networks. Using different mobile applications connecting to cloud computing, the applications of the IoHT are remote healthcare monitoring systems, high blood pressure monitoring, online medical counseling, and others. These applications are designed based on a client–server architecture based on various standards such as the common object request broker (CORBA), a service-oriented architecture (SOA), remote method invocation (RMI), and others. However, these applications do not directly support the many healthcare nodes and blockchain technology in the current standard. Thus, this study devises a potent blockchain-enabled socket RPC IoHT framework for medical enterprises (e.g., healthcare applications). The goal is to minimize service costs, blockchain security costs, and data storage costs in distributed mobile cloud networks. Simulation results show that the proposed blockchain-enabled socket RPC minimized the service cost by 40%, the blockchain cost by 49%, and the storage cost by 23% for healthcare applications

    Culturally Adapted Motivational Interviewing with Cognitive Behavior Therapy and Mindfulness Based Relapse Prevention for Substance Use Disorder in Pakistan (CAMAIB): Protocol of a feasibility factorial randomised controlled trial.

    Get PDF
    Background: The use of psychoactive substances significantly impacts the health, social and economic aspects of families, communities and nations. There is a need to develop and test psychological interventions aimed for individuals with substance use disorder (SUD) in lower- and middle-income countries (LMICs), such as in Pakistan. The aim of this exploratory trial is to test the feasibility and acceptability of two culturally adapted psychological interventions in a factorial randomised controlled trial (RCT). Methods: The proposed project will be conducted in three phases. The first phase of the study will focus on cultural adaptation of the interventions through qualitative interviews with key stakeholders. The second phase will be to refine and produce manually assisted interventions. Third and last stage would be to assess the feasibility of the culturally adapted interventions through a factorial RCT. The study will be carried out in Karachi, Hyderabad, Peshawar, Lahore and Rawalpindi, Pakistan. Recruitment of participants will take place from primary care and volunteer organisations/drug rehabilitation centres. A total of 260 individuals diagnosed with SUD (n = 65) in each of the four arms will be recruited. The intervention will be delivered weekly over a period of 12 weeks in both individual and group settings. Assessments will be carried out at baseline, at 12th week (after completion of intervention) and 24th week post-randomisation. The analysis will determine the feasibility of recruitment, randomisation, retention and intervention delivery. Acceptability of intervention will be determined in terms of adherence to intervention, i.e. the mean number of sessions attended, number of home assignments completed, attrition rates, as well as through process evaluation to understand the implementation process, context, participants’ satisfaction, and impact of the study intervention. The health resource use and impact on the quality of life will be established through health economic data. Discussion: This study will provide evidence for feasibility and acceptability of culturally adapted manually assisted psychological interventions for individuals with SUD in the context of Pakistan. The study will have clinical implications if intervention is proven feasible and acceptable.

    A randomised double-blind placebo-controlled trial of minocycline and/or Omega-3 fatty acids added to treatment as usual for At Risk Mental States (NAYAB): study protocol

    Get PDF
    Background The At Risk Mental State (ARMS) describes individuals at high risk of developing schizophrenia or psychosis. The use of antipsychotics in this population is not supported because most individuals with ARMS are unlikely to develop psychosis. Anti-inflammatory treatments and polyunsaturated fatty acids (PUFAs) may have some beneficial effects in the treatment of ARMS. There have been no controlled clinical trials that have investigated the use of minocycline for ARMS and no trials involving PUFAs in combination with other proposed treatments. There is a need to find effective, tolerable and inexpensive interventions for ARMS that are available both in high, low and middle-income countries. Methods A six-month intervention study of minocycline and/or Omega-3 fatty acids added to treatment as usual (TAU) in patients with ARMS will be conducted in Pakistan using a randomised, placebo-controlled, double-blind factorial design. 320 consenting patients with capacity will be recruited from community, general practitioner clinics and psychiatric units. Allowing for a 25% dropout rate, we will recruit 59 completing participants to each study arm, and 236 will complete in total. We will determine whether the addition of minocycline and/or Omega-3 fatty acids to TAU attenuates rate of transition from ARMS to first-episode psychosis and improves symptoms and/or level of functioning in ARMS. We will also investigate whether any candidate risk factors such as negative symptoms, influence treatment response in the ARMS group. The primary efficacy end-point is conversion to psychotic disorder at 12 months post study entry. Analysis will be by intention-to-treat, using analysis-of variance, chi-squared tests and adjusted odds ratios to assess between-group differences. Cox regression analyses will be used to analyse potential between-group differences in time-to-onset of psychosis. Discussion The outcomes of this trial will provide evidence of the potential benefits of minocycline and PUFAs in the treatment of ARMS. Both minocycline and PUFAs are inexpensive are readily available in low/middle-income countries such as Pakistan, and if evidenced, may prove to be safe and effective for treating ARMS

    <p>Abstract</p> <p>Background</p> <p>Research undertaken in developing countries has assessed discrepancies in police reporting of Road Traffic Injury (RTI) for urban settings only. The objective of this study was to assess differences in RTI reporting across police, ambulance, and hospital Emergency Department (ED) datasets on an interurban road section in Pakistan.</p> <p>Methods</p> <p>The study setting was the 196-km long Karachi-Hala road section. RTIs reported to the police, Edhi Ambulance Service (EAS), and five hospital EDs in Karachi during 2008 (Jan to Dec) were compared in terms of road user involved (pedestrians, motorcyclists, four-wheeled vehicle occupants) and outcome (died or injured). Further, records from these data were matched to assess ascertainment of traffic injuries and deaths by the three datasets.</p> <p>Results</p> <p>A total of 143 RTIs were reported to the police, 531 to EAS, and 661 to hospital EDs. Fatality per hundred traffic injuries was twice as high in police records (19 per 100 RTIs) than in ambulance (10 per 100 RTIs) and hospital ED records (9 per 100 RTIs). Pedestrian and motorcyclist involvement per hundred traffic injuries was lower in police records (8 per 100 RTIs) than in ambulance (17 per 100 RTIs) and hospital ED records (43 per 100 RTIs). Of the 119 deaths independently identified after matching, police recorded 22.6%, EAS 46.2%, and hospital ED 50.4%. Similarly, police data accounted for 10.6%, EAS 43.5%, and hospital ED 54.9% of the 1 095 independently identified injured patients.</p> <p>Conclusions</p> <p>Police reporting, particularly of non-fatal RTIs and those involving vulnerable road users, should be improved in Pakistan.</p

    BackgroundInflammatory mechanisms are thought to contribute to the onset of psychosis in persons with an at-risk mental state (ARMS). We investigated whether the anti-inflammatory properties of minocycline and omega-3 polyunsaturated fatty acids (omega-3), alone or synergistically, would prevent transition to psychosis in ARMS in a randomised, double-blind, placebo-controlled trial in Pakistan.Methods10,173 help-seeking individuals aged 16-35 years were screened using the Prodromal Questionaire-16. Individuals scoring 6 and over were interviewed using the Comprehensive Assessment of At-Risk Mental States (CAARMS) to confirm ARMS. Participants (n = 326) were randomised to minocycline, omega-3, combined minocycline and omega-3 or to double placebo for 6 months. The primary outcome was transition to psychosis at 12 months.FindingsForty-five (13.8 %) participants transitioned to psychosis. The risk of transition was greater in those randomised to omega-3 alone or in combination with minocycline (17.3.%), compared to 10.4 % in those not exposed to omega-3; a risk-ratio (RR) of 1.67, 95 % CI [0.95, 2.92] p = 0.07. The RR for transitions on minocycline vs. no minocycline was 0.86, 95 % CI [0.50, 1.49] p > 0.10. In participants who did not become psychotic, CAARMS and depression symptom scores were reduced at six and twelve months (mean CAARMS difference = 1.43; 95 % CI [0.33, 1.76] p InterpretationIn keeping with other studies, omega-3 appears to have beneficial effects on ARMS and mood symptom severity but it increased transition to psychosis, which may reflect metabolic or developmental consequences of chronic poor nutrition in the population. Transition to psychosis was too rare to reveal a preventative effect of minocycline but minocycline did not improve symptom severity. ARMS symptom severity and transition to psychosis appear to have distinct pathogeneses which are differentially modulated by omega-3 supplementation.FundingThe study was funded by the Stanley Research Medical Institute

    A randomised clinical trial of methotrexate points to possible efficacy and adaptive immune dysfunction in psychosis

    NMDA autoantibody encephalitis presenting as schizophrenia suggests the possible role of adaptive cell-mediated immunity in idiopathic schizophrenia. However, to our knowledge there have been no trials of the immune-suppressant methotrexate in schizophrenia. We tested if low-dose methotrexate as used in the treatment of systemic autoimmune disorders would be tolerable and effective in people with schizophrenia in a feasibility study. Ninety-two participants within 5 years of schizophrenia diagnosis were recruited from inpatient and outpatient facilities in Karachi, Pakistan. They were randomised to receive once weekly 10-mg oral methotrexate (n = 45) or matching placebo (n = 47) both with daily 5-mg folic acid, in addition to treatment as usual for 12 weeks. There were eight dropouts per group. Side effects were non-significantly more common in those on methotrexate and were not severe. One person developed leukopenia. Positive symptom scores improved more in those receiving methotrexate than placebo (ÎČ = −2.5; [95% CI −4.7 to −0.4]), whereas negative symptoms were unaffected by treatment (ÎČ = −0.39; [95% CI −2.01 to 1.23]). There were no immune biomarkers but methotrexate did not affect group mean leucocyte counts or C-reactive protein. We conclude that further studies are feasible but should be focussed on subgroups identified by advances in neuroimmune profiling. Methotrexate is thought to work in autoimmune disorders by resetting systemic regulatory T-cell control of immune signalling; we show that a similar action in the CNS would account for otherwise puzzling features of the immuno-pathogenesis of schizophrenia

    IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
