Bertolotti's Syndrome , An Important Etiology of Low Back Pain On X ray Lumbo-sacral Spine Among Young Population
Objective:Ā To find out frequency of Bertolottiās syndrome on Xāray lumbosacral spine in young adults having low backache.Methodology:This is retrospective descriptive cross sectional study done in Radiology Department POF hospital Wah Cantt, from Nov 2017 to Oct 2019. Sample size was 600 X-ray lumbosacral spine of patients with low back pain between 15-40 years of age. 200 cases with history of trauma were excluded. Data analysis of 400 included cases was done by SPSS-22. Percentage of etiologies of low backache, lumbosacral transitional vertebra (LSTV), Bertolottiās syndrome and Castellvi types of LSTV was calculated. Mean age with SD and percentage of gender distribution among cases of Bertolottiās syndrome was calculated.Results: Among 400 patients, 120 (30%) had LSTV, 264 (66%)Ā had muscle spasm, 6(1.5%) had Pottās disease and 10 (2.5%) had spinal metastasis. 120 patients with LSTV, 32 ( 26.6%)Ā had Bertolottiās syndrome and 88(73.3%) had normal transverse processes. Mean age with Bertolotti syndrome was 29.96+0.417 years. 20 patients (62%, n=32) were female and 12 (37.5%, n=32) were male. Among 32 patients with Bertolottiās syndrome, 4 (12.5%) were Castellvi typeāI, 10 (31.25%) were Castellvi type-II, 12 (37.5%) were Castellvi type-III and 6 (18.7%) were Castellvi type- IV.Conclusion: Bertolottiās syndrome is a frequently observed etiology of backache in young patients. Importance of imaging is not only in the diagnosis but also in identification and exact enumeration of LSTV, to avoid unintended level treatment
Analysis of Primary Surgery and Medical Treatment in the Management of Primary Open Angle Glaucoma
Background: To evaluate and compare the efficacy of medical and surgical treatment for management of primary open angle glaucoma (POAG). Methods: Study included a total of 32 patients with 60 eyes, who were divided into two groups. 31 eyes were included in group A and were given medical treatment. 29 eyes were included in group B and were managed with primary surgery (Trabeculectomy). Results: The IOP was controlled in group A with one drug in 62.5% (n=10), with two drugs in 25% (n=4)and with three drugs in 6.25% (n=1). The IOP of group B patients was controlled by surgery alone in 81.25% (n=13) and with surgery and drugs in 18.75% (n=3). P values were found to be constantly less than 0.001. Conclusion: Primary surgery i.e. trabeculectomy is a superior modality of treatment for POAG as compared to medical therapy as it is cost-effective, IOP control is uniform and compliance is not a problem
Characteristics of the Contingent Negative Variation during Lower Limb Functional Movement with an Audio-Visual Cue
Background: The contingent negative variation (CNV) is a negative shift in electroencephalography (EEG) related to the planning and execution of an externally cued movement task. The CNV has the potential to be applied within stroke rehabilitation; however, there is insufficient knowledge about the CNV characteristics under movement conditions relevant to rehabilitation. This study explores the CNV characteristics during a functional movement task (versus a simple movement task) and when using an audio-visual cue that has been previously evaluated for its usability in stroke rehabilitation (versus a simple visual cue). Methods: Thirty healthy participants performed five randomized movement tasks: simple ankle dorsiflexion with a visual cue (1), audio-visual cue (2), and auditory-only cue (3), and sit-to-stand with a visual (4) and audio-visual cue (5). Fifty repetitions of each movement were performed while continuous EEG was recorded. The band-passed and Laplacian-filtered (Cz) EEG was averaged for each condition and the peak negativity (PN) latency and amplitude were identified. Results: PN latency was significantly later during sit-to-stand with the audio-visual cue versus the visual cue (p = 0.027). PN amplitude was significantly larger during sit-to-stand versus ankle dorsiflexion, with both visual and audio-visual cues (p < 0.0001). Conclusion: The CNV changes under more complex movement conditions. Assumptions about the MRCP from simple laboratory recordings should not be generalized to the rehabilitation setting

Objective: To determine if a goal-directed ECG workshop improves ECG interpretation competency and confidence among the house officers in PNS Shifa Hospital.
Study Design: Prospective comparative study.
Place and Duration of Study: Pakistan Naval Ship Shifa Hospital, Karachi Pakistan, from Jan to Dec 2021.
Methodology: ECG workshops were conducted for House Officers in batches. The participants were asked to complete a questionnaire testing their ECG interpretation competency before and after the workshop and self-report their confidence level in ECG interpretation.
Results: Sixty-eight house officers participated in the workshops and completed the test. There were 41(60.29%) female and 27(39.7%) male participants. The statistics showed significant improvement in ECG competency (p<0.001). In addition, the pre and post-workshop confidence levels also showed significant improvement (p<0.001).
Conclusion: A goal-directed ECG workshop improves house officersā competency and confidence in ECG interpretation
Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study
Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.
Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.
Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58Ā·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31Ā·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10Ā·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12Ā·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9Ā·4%] of 7339 patients), middle (549 [14Ā·0%] of 3918 patients), and low (298 [23Ā·2%] of 1282) HDI (p < 0Ā·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17Ā·8%] of 574 patients in high-HDI countries; 74 [31Ā·4%] of 236 patients in middle-HDI countries; 72 [39Ā·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1Ā·60, 95% credible interval 1Ā·05ā2Ā·37; p=0Ā·030). 132 (21Ā·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16Ā·6%) of 295 patients in high-HDI countries, in 37 (19Ā·8%) of 187 patients in middle-HDI countries, and in 46 (35Ā·9%) of 128 patients in low-HDI countries (p < 0Ā·001).
Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication
Burden of disease scenarios for 204 countries and territories, 2022ā2050: a forecasting analysis for the Global Burden of Disease Study 2021
Background: Future trends in disease burden and drivers of health are of great interest to policy makers and the public at large. This information can be used for policy and long-term health investment, planning, and prioritisation. We have expanded and improved upon previous forecasts produced as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) and provide a reference forecast (the most likely future), and alternative scenarios assessing disease burden trajectories if selected sets of risk factors were eliminated from current levels by 2050. Methods: Using forecasts of major drivers of health such as the Socio-demographic Index (SDI; a composite measure of lag-distributed income per capita, mean years of education, and total fertility under 25 years of age) and the full set of risk factor exposures captured by GBD, we provide cause-specific forecasts of mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) by age and sex from 2022 to 2050 for 204 countries and territories, 21 GBD regions, seven super-regions, and the world. All analyses were done at the cause-specific level so that only risk factors deemed causal by the GBD comparative risk assessment influenced future trajectories of mortality for each disease. Cause-specific mortality was modelled using mixed-effects models with SDI and time as the main covariates, and the combined impact of causal risk factors as an offset in the model. At the all-cause mortality level, we captured unexplained variation by modelling residuals with an autoregressive integrated moving average model with drift attenuation. These all-cause forecasts constrained the cause-specific forecasts at successively deeper levels of the GBD cause hierarchy using cascading mortality models, thus ensuring a robust estimate of cause-specific mortality. For non-fatal measures (eg, low back pain), incidence and prevalence were forecasted from mixed-effects models with SDI as the main covariate, and YLDs were computed from the resulting prevalence forecasts and average disability weights from GBD. Alternative future scenarios were constructed by replacing appropriate reference trajectories for risk factors with hypothetical trajectories of gradual elimination of risk factor exposure from current levels to 2050. The scenarios were constructed from various sets of risk factors: environmental risks (Safer Environment scenario), risks associated with communicable, maternal, neonatal, and nutritional diseases (CMNNs; Improved Childhood Nutrition and Vaccination scenario), risks associated with major non-communicable diseases (NCDs; Improved Behavioural and Metabolic Risks scenario), and the combined effects of these three scenarios. Using the Shared Socioeconomic Pathways climate scenarios SSP2-4.5 as reference and SSP1-1.9 as an optimistic alternative in the Safer Environment scenario, we accounted for climate change impact on health by using the most recent Intergovernmental Panel on Climate Change temperature forecasts and published trajectories of ambient air pollution for the same two scenarios. Life expectancy and healthy life expectancy were computed using standard methods. The forecasting framework includes computing the age-sex-specific future population for each location and separately for each scenario. 95% uncertainty intervals (UIs) for each individual future estimate were derived from the 2Ā·5th and 97Ā·5th percentiles of distributions generated from propagating 500 draws through the multistage computational pipeline. Findings: In the reference scenario forecast, global and super-regional life expectancy increased from 2022 to 2050, but improvement was at a slower pace than in the three decades preceding the COVID-19 pandemic (beginning in 2020). Gains in future life expectancy were forecasted to be greatest in super-regions with comparatively low life expectancies (such as sub-Saharan Africa) compared with super-regions with higher life expectancies (such as the high-income super-region), leading to a trend towards convergence in life expectancy across locations between now and 2050. At the super-region level, forecasted healthy life expectancy patterns were similar to those of life expectancies. Forecasts for the reference scenario found that health will improve in the coming decades, with all-cause age-standardised DALY rates decreasing in every GBD super-region. The total DALY burden measured in counts, however, will increase in every super-region, largely a function of population ageing and growth. We also forecasted that both DALY counts and age-standardised DALY rates will continue to shift from CMNNs to NCDs, with the most pronounced shifts occurring in sub-Saharan Africa (60Ā·1% [95% UI 56Ā·8ā63Ā·1] of DALYs were from CMNNs in 2022 compared with 35Ā·8% [31Ā·0ā45Ā·0] in 2050) and south Asia (31Ā·7% [29Ā·2ā34Ā·1] to 15Ā·5% [13Ā·7ā17Ā·5]). This shift is reflected in the leading global causes of DALYs, with the top four causes in 2050 being ischaemic heart disease, stroke, diabetes, and chronic obstructive pulmonary disease, compared with 2022, with ischaemic heart disease, neonatal disorders, stroke, and lower respiratory infections at the top. The global proportion of DALYs due to YLDs likewise increased from 33Ā·8% (27Ā·4ā40Ā·3) to 41Ā·1% (33Ā·9ā48Ā·1) from 2022 to 2050, demonstrating an important shift in overall disease burden towards morbidity and away from premature death. The largest shift of this kind was forecasted for sub-Saharan Africa, from 20Ā·1% (15Ā·6ā25Ā·3) of DALYs due to YLDs in 2022 to 35Ā·6% (26Ā·5ā43Ā·0) in 2050. In the assessment of alternative future scenarios, the combined effects of the scenarios (Safer Environment, Improved Childhood Nutrition and Vaccination, and Improved Behavioural and Metabolic Risks scenarios) demonstrated an important decrease in the global burden of DALYs in 2050 of 15Ā·4% (13Ā·5ā17Ā·5) compared with the reference scenario, with decreases across super-regions ranging from 10Ā·4% (9Ā·7ā11Ā·3) in the high-income super-region to 23Ā·9% (20Ā·7ā27Ā·3) in north Africa and the Middle East. The Safer Environment scenario had its largest decrease in sub-Saharan Africa (5Ā·2% [3Ā·5ā6Ā·8]), the Improved Behavioural and Metabolic Risks scenario in north Africa and the Middle East (23Ā·2% [20Ā·2ā26Ā·5]), and the Improved Nutrition and Vaccination scenario in sub-Saharan Africa (2Ā·0% [ā0Ā·6 to 3Ā·6]). Interpretation: Globally, life expectancy and age-standardised disease burden were forecasted to improve between 2022 and 2050, with the majority of the burden continuing to shift from CMNNs to NCDs. That said, continued progress on reducing the CMNN disease burden will be dependent on maintaining investment in and policy emphasis on CMNN disease prevention and treatment. Mostly due to growth and ageing of populations, the number of deaths and DALYs due to all causes combined will generally increase. By constructing alternative future scenarios wherein certain risk exposures are eliminated by 2050, we have shown that opportunities exist to substantially improve health outcomes in the future through concerted efforts to prevent exposure to well established risk factors and to expand access to key health interventions
Global burden and strength of evidence for 88 risk factors in 204 countries and 811 subnational locations, 1990ā2021: a systematic analysis for the Global Burden of Disease Study 2021
Background: Understanding the health consequences associated with exposure to risk factors is necessary to inform public health policy and practice. To systematically quantify the contributions of risk factor exposures to specific health outcomes, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 aims to provide comprehensive estimates of exposure levels, relative health risks, and attributable burden of disease for 88 risk factors in 204 countries and territories and 811 subnational locations, from 1990 to 2021. Methods: The GBD 2021 risk factor analysis used data from 54 561 total distinct sources to produce epidemiological estimates for 88 risk factors and their associated health outcomes for a total of 631 riskāoutcome pairs. Pairs were included on the basis of data-driven determination of a riskāoutcome association. Age-sex-location-year-specific estimates were generated at global, regional, and national levels. Our approach followed the comparative risk assessment framework predicated on a causal web of hierarchically organised, potentially combinative, modifiable risks. Relative risks (RRs) of a given outcome occurring as a function of risk factor exposure were estimated separately for each riskāoutcome pair, and summary exposure values (SEVs), representing risk-weighted exposure prevalence, and theoretical minimum risk exposure levels (TMRELs) were estimated for each risk factor. These estimates were used to calculate the population attributable fraction (PAF; ie, the proportional change in health risk that would occur if exposure to a risk factor were reduced to the TMREL). The product of PAFs and disease burden associated with a given outcome, measured in disability-adjusted life-years (DALYs), yielded measures of attributable burden (ie, the proportion of total disease burden attributable to a particular risk factor or combination of risk factors). Adjustments for mediation were applied to account for relationships involving risk factors that act indirectly on outcomes via intermediate risks. Attributable burden estimates were stratified by Socio-demographic Index (SDI) quintile and presented as counts, age-standardised rates, and rankings. To complement estimates of RR and attributable burden, newly developed burden of proof risk function (BPRF) methods were applied to yield supplementary, conservative interpretations of riskāoutcome associations based on the consistency of underlying evidence, accounting for unexplained heterogeneity between input data from different studies. Estimates reported represent the mean value across 500 draws from the estimate's distribution, with 95% uncertainty intervals (UIs) calculated as the 2Ā·5th and 97Ā·5th percentile values across the draws. Findings: Among the specific risk factors analysed for this study, particulate matter air pollution was the leading contributor to the global disease burden in 2021, contributing 8Ā·0% (95% UI 6Ā·7ā9Ā·4) of total DALYs, followed by high systolic blood pressure (SBP; 7Ā·8% [6Ā·4ā9Ā·2]), smoking (5Ā·7% [4Ā·7ā6Ā·8]), low birthweight and short gestation (5Ā·6% [4Ā·8ā6Ā·3]), and high fasting plasma glucose (FPG; 5Ā·4% [4Ā·8ā6Ā·0]). For younger demographics (ie, those aged 0ā4 years and 5ā14 years), risks such as low birthweight and short gestation and unsafe water, sanitation, and handwashing (WaSH) were among the leading risk factors, while for older age groups, metabolic risks such as high SBP, high body-mass index (BMI), high FPG, and high LDL cholesterol had a greater impact. From 2000 to 2021, there was an observable shift in global health challenges, marked by a decline in the number of all-age DALYs broadly attributable to behavioural risks (decrease of 20Ā·7% [13Ā·9ā27Ā·7]) and environmental and occupational risks (decrease of 22Ā·0% [15Ā·5ā28Ā·8]), coupled with a 49Ā·4% (42Ā·3ā56Ā·9) increase in DALYs attributable to metabolic risks, all reflecting ageing populations and changing lifestyles on a global scale. Age-standardised global DALY rates attributable to high BMI and high FPG rose considerably (15Ā·7% [9Ā·9ā21Ā·7] for high BMI and 7Ā·9% [3Ā·3ā12Ā·9] for high FPG) over this period, with exposure to these risks increasing annually at rates of 1Ā·8% (1Ā·6ā1Ā·9) for high BMI and 1Ā·3% (1Ā·1ā1Ā·5) for high FPG. By contrast, the global risk-attributable burden and exposure to many other risk factors declined, notably for risks such as child growth failure and unsafe water source, with age-standardised attributable DALYs decreasing by 71Ā·5% (64Ā·4ā78Ā·8) for child growth failure and 66Ā·3% (60Ā·2ā72Ā·0) for unsafe water source. We separated risk factors into three groups according to trajectory over time: those with a decreasing attributable burden, due largely to declining risk exposure (eg, diet high in trans-fat and household air pollution) but also to proportionally smaller child and youth populations (eg, child and maternal malnutrition); those for which the burden increased moderately in spite of declining risk exposure, due largely to population ageing (eg, smoking); and those for which the burden increased considerably due to both increasing risk exposure and population ageing (eg, ambient particulate matter air pollution, high BMI, high FPG, and high SBP). Interpretation: Substantial progress has been made in reducing the global disease burden attributable to a range of risk factors, particularly those related to maternal and child health, WaSH, and household air pollution. Maintaining efforts to minimise the impact of these risk factors, especially in low SDI locations, is necessary to sustain progress. Successes in moderating the smoking-related burden by reducing risk exposure highlight the need to advance policies that reduce exposure to other leading risk factors such as ambient particulate matter air pollution and high SBP. Troubling increases in high FPG, high BMI, and other risk factors related to obesity and metabolic syndrome indicate an urgent need to identify and implement interventions
Relativism and Skepticism: A Psychoanalytic Study of Cate Kennedyās Like a House on Fire
This paper focuses on the exploration of the complexity of human relationships, the underlying motivations and the psychological dynamics that drive the charactersā engagement with relativism and skepticism in Cate Kennedyās Like a House on Fire. Through a psychoanalytic prism grounded in Eriksonās developmental theory, this paper sheds light on the characterās internal problems, beliefs and inner reflections, aligning them with the interplay between personal truth and societal influence. All this leads to reflect the Psychosocial challenges of Eriksonās four stages of development. This study determines that the charactersā relativistic viewpoints and skeptical stances contribute to their psychological evolution, while they keep grappling with their struggles and trauma. The dominant worth of this study lies in its contribution to understanding the role of relativism and skepticism in the intricate phenomenon of human development and the formation of identities
