RESUMO

PURPOSE: To examine the association of marital status with prostate cancer outcomes in a racially-diverse cohort. METHODS: The study population consisted of men (1010 Black; 1070 White) with incident prostate cancer from the baseline North Carolina-Louisiana Prostate Cancer (PCaP) cohort. Marital status at time of diagnosis and screening history were determined by self-report. The binary measure of marital status was defined as married (including living as married) vs. not married (never married, divorced/separated, or widowed). High-aggressive tumors were defined using a composite measure of PSA, Gleason Score, and stage. Definitive treatment was defined as receipt of radical prostatectomy or radiation. Multivariable logistic regression was used to examine the association of marital status with (1) high-aggressive tumors, (2) receipt of definitive treatment, and (3) screening history among Black and White men with prostate cancer. RESULTS: Black men were less likely to be married than White men (68.1% vs. 83.6%). Not being married (vs. married) was associated with increased odds of high-aggressive tumors in the overall study population (adjusted Odds Ratio (aOR): 1.56; 95% Confidence Interval (CI): 1.20-2.02) and both Black and White men in race-stratified analyses. Unmarried men were less likely to receive definitive treatment in the overall study population (aOR: 0.68; 95% CI: 0.54-0.85). In race-stratified analyses, unmarried Black men were less likely to receive definitive treatment. Both unmarried Black and White men were less likely to have a history of prostate cancer screening than married men. CONCLUSION: Lower rates of marriage among Black men might signal decreased support for treatment decision-making, symptom management, and caregiver support which could potentially contribute to prostate cancer disparities.

RESUMO

Fish oil has been known for its antioxidant, cardioprotective, anti-inflammatory, and neuroprotective characteristics due to the presence of polyunsaturated fatty acids (PUFAs) that are essential for optimal brain function and mental health. The present study investigated the effect of Carcharhinus Bleekeri (Shark Fish) oil on learning and memory functions in scopolamine-induced amnesia in rats. Locomotor and memory-enhancing activity in scopolamine-induced amnesic rats was investigated by assessing the open field and passive avoidance paradigm. Forty male Albino mice were divided into 4 equal groups (n = 10) as bellow: 1 - control (received 0.9% saline), 2 - SCOP (received scopolamine 2 mg/kg for 21 days), 3 - SCOP + SFO (received scopolamine and fish oil 5 mg/kg/ day for 21 days), 4 - SCOP + Donepezil groups (received 3 mg/kg/day for 21 days). SFO produced significant (P < 0.01) locomotor and memory-enhancing activities in open-field and passive avoidance paradigm models. Additionally, SFO restored the Acetylcholine (ACh) concentration in the hippocampus (p < 0.05) and remarkably prevented the degradation of monoamines. Histology of brain tissue showed marked cellular distortion in the scopolamine-treated group, while the SFO treatment restored distortion in the brain's hippocampus region. These results suggest that the SFO significantly ameliorates scopolamine-induced spatial memory impairment by attenuating the ACh and monoamine concentrations in the rat's hippocampus.

RESUMO

OBJECTIVE: To evaluate the impact of post-diagnostic metformin or statin use and duration on risk of biochemical recurrence in a racially-diverse cohort of Veterans. METHODS: The population consisted of men diagnosed with prostate cancer in the Veterans Health Administration and treated with either radical prostatectomy or radiation (Full cohort n = 65,759, Black men n = 18,817, White men n = 46,631, Other = 311). The association between post-diagnostic (1) metformin and (2) statin use with biochemical recurrence was assessed using multivariable, time-varying Cox Proportional Hazard Models for the overall cohort and by race. In a secondary analysis, metformin and statin duration were evaluated. RESULTS: Post-diagnostic metformin use was not associated with biochemical recurrence (multivariable-adjusted hazard ratio [aHR]: 1.01; 95% confidence interval [CI]: 0.94, 1.09), with similar results observed for both Black and White men. However, duration of metformin use was associated with a reduced risk of biochemical recurrence in the cohort overall (HR: 0.94; 95% CI: 0.92, 0.95) as well as both Black and White men. By contrast, statin use was associated with a reduced risk of biochemical recurrence (HR: 0.83; 95% CI: 0.79, 0.88) in the overall cohort as well as both White and Black men. Duration of statin use was also inversely associated with biochemical recurrence in all groups. CONCLUSION: Post-diagnostic metformin and statin use have the potential to prevent biochemical recurrence in men diagnosed with prostate cancer.

RESUMO

INTRODUCTION: Financial toxicity (FT) is a growing concern among cancer survivors that adversely affects the quality of life and survival. Individuals diagnosed with aggressive cancers are often at a greater risk of experiencing FT. The objectives of this study were to estimate FT among prostate cancer (PCa) survivors after 10-15 years of diagnosis, assess the relationship between PCa aggressiveness at diagnosis and FT, and examine whether current cancer treatment status mediates the relationship between PCa aggressiveness and FT. METHODS: PCa patients enrolled in the North Carolina-Louisiana Prostate Cancer Project (PCaP) were recontacted for long-term follow-up. The prevalence of FT in the PCaP cohort was estimated. FT was estimated using the COmprehensive Score for Financial Toxicity, a validated measure of FT. The direct effect of PCa aggressiveness and an indirect effect through current cancer treatment on FT was examined using causal mediation analysis. RESULTS: More than one-third of PCa patients reported experiencing FT. PCa aggressiveness was significantly independently associated with high FT; high aggressive PCa at diagnosis had more than twice the risk of experiencing FT than those with low or intermediate aggressive PCa (adjusted odds ratio [aOR] = 2.13, 95% CI = 1.14-3.96). The proportion of the effect of PCa aggressiveness on FT, mediated by treatment status, was 10%, however, the adjusted odds ratio did not indicate significant evidence of mediation by treatment status (aOR = 1.05, 95% CI = 0.95-1.20). CONCLUSIONS: Aggressive PCa was associated with high FT. Future studies should collect more information about the characteristics of men with high FT and identify additional risk factors of FT.

RESUMO

Therapy-related myeloid neoplasms (t-MNs) are high-risk late effects with poorly understood pathogenesis in cancer survivors. It has been postulated that, in some cases, hematopoietic stem and progenitor cells (HSPCs) harboring mutations are selected for by cytotoxic exposures and transform. Here, we evaluate this model in the context of deficiency of CUX1, a transcription factor encoded on chromosome 7q and deleted in half of t-MN cases. We report that CUX1 has a critical early role in the DNA repair process in HSPCs. Mechanistically, CUX1 recruits the histone methyltransferase EHMT2 to DNA breaks to promote downstream H3K9 and H3K27 methylation, phosphorylated ATM retention, subsequent γH2AX focus formation and propagation, and, ultimately, 53BP1 recruitment. Despite significant unrepaired DNA damage sustained in CUX1-deficient murine HSPCs after cytotoxic exposures, they continue to proliferate and expand, mimicking clonal hematopoiesis in patients postchemotherapy. As a consequence, preexisting CUX1 deficiency predisposes mice to highly penetrant and rapidly fatal therapy-related erythroleukemias. These findings establish the importance of epigenetic regulation of HSPC DNA repair and position CUX1 as a gatekeeper in myeloid transformation.

RESUMO

High levels of reactive oxygen species (ROS) in the body and diabetes are key factors for the development of hypercholesteremia and related neuropathic pains. Current study aimed to compare the antioxidant, antidiabetic and analgesic activities of aqueous methanolic extracts of C. viminalis L. and A. rosea L. leaves. HPLC method was used for phenolic content evaluation. Antioxidant capacity was determined by DPPH and analgesic activity was performed via acetic acid induced writhing reflex test. Whereas the antidiabetic activity was performed on Alloxan induced diabetes model. HPLC analysis indicated the presence of phenols in both extracts. Based on DPPH radical scavenging activity, C. viminalis and A.rosea L. both leaves extracts showed strong scavenging activity (IC50, 11.96±0.64lg/mL) and (IC50, 10.11±0.74lg/mL) respectively. Antidiabetic effect of C. viminalis L and A. rosea L. were also significant (p<0.05). Further biochemical analysis showed both leaves extracts significantly (P<0.05) reduces glucose, Low density lipid (LDL), triglycerides (TG), total cholesterol (TC) and urea while high density lipid (HDL) were improved. In writhing reflex test both extracts exhibited significant (P<0.01) analgesic activity which was comparable to Aspirin. In conclusion both C. viminalis L. and A. rosea L. leaves extracts displayed significant antioxidant, analgesic and antidiabetic activity.

RESUMO

BACKGROUND: Long-term population-based cohort studies of men diagnosed with prostate cancer are limited. However, adverse outcomes can occur many years after treatment. Herein, we aim to assess the utility of using claims data to identify prostate cancer progression 10-15 years after diagnosis. METHODS: The study population was derived from the North Carolina-Louisiana Prostate Cancer Project (PCaP). PCaP-North Carolina (NC) included 1031 men diagnosed with prostate cancer from 2004 to 2009. An initial follow-up with a survey and manual medical record abstraction occurred from 2008 to 2011 (Follow-up 1). Herein, we extended this follow-up with linkage to healthcare claims data from North Carolina (2011-2017) and a second, supplementary 10-year follow-up survey (2018-2020) (Follow-up 2). Vital statistics data also were utilized. Long-term oncological progression was determined using these data sources in combination with expert clinical input. RESULTS: Among the 1031 baseline PCaP-NC participants, 652 were linked to medical claims. Forty-two percent of the men had insurance coverage for the entire 72 months of follow-up. In addition, 275 baseline participants completed the supplementary 10-year follow-up survey. Using all sources of follow-up data, we identified a progression event in 259 of 1031 (25%) men with more than 10 years of follow-up data after diagnosis. CONCLUSIONS: Understanding long-term clinical outcomes is essential for improving the lives of prostate cancer survivors. However, access and utility of long-term clinical outcomes with claims alone remain a challenge due to individualized agreements required with each insurer for data access, lack of detailed clinical information, and gaps in insurance coverage. We were able to utilize claims data to determine long-term progression due to several unique advantages that included the availability of detailed baseline clinical characteristics and treatments, detailed manually abstracted clinical data at 5 years of follow-up, vital statistics data, and a supplementary 10-year follow-up survey.

RESUMO

BACKGROUND: Existing evidence suggests that there is an association between body size and prevalent Benign Prostatic Hyperplasia (BPH)-related outcomes and nocturia. However, there is limited evidence on the association between body size throughout the life-course and incident BPH-related outcomes. METHODS: Our study population consisted of men without histories of prostate cancer, BPH-related outcomes, or nocturia in the intervention arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) (n = 4710). Associations for body size in early- (age 20), mid- (age 50) and late-life (age ≥ 55, mean age 60.7 years) and weight change with incident BPH-related outcomes (including self-reported nocturia and physician diagnosis of BPH, digital rectal examination-estimated prostate volume ≥ 30 cc, and prostate-specific antigen [PSA] concentration > 1.4 ng/mL) were examined using Poisson regression with robust variance estimation. RESULTS: Men who were obese in late-life were 25% more likely to report nocturia (Relative Risk (RR): 1.25, 95% Confidence Interval (CI): 1.11-1.40; p-trendfor continuous BMI < 0.0001) and men who were either overweight or obese in late-life were more likely to report a prostate volume ≥ 30 cc (RRoverweight: 1.13, 95% CI 1.07-1.21; RRobese: 1.10, 95% CI 1.02-1.19; p-trendfor continuous BMI = 0.017) as compared to normal weight men. Obesity at ages 20 and 50 was similarly associated with both nocturia and prostate volume ≥ 30 cc. Considering trajectories of body size, men who were normal weight at age 20 and became overweight or obese by later-life had increased risks of nocturia (RRnormal to overweight: 1.09, 95% CI 0.98-1.22; RRnormal to obese: 1.28, 95% CI 1.10-1.47) and a prostate volume ≥ 30 cc (RRnormal to overweight: 1.12, 95% CI 1.05-1.20). Too few men were obese early in life to examine the independent effect of early-life body size. Later-life body size modified the association between physical activity and nocturia. CONCLUSIONS: We found that later-life body size, independent of early-life body size, was associated with adverse BPH outcomes, suggesting that interventions to reduce body size even late in life can potentially reduce the burden of BPH-related outcomes and nocturia.

RESUMO

BACKGROUND: The disruptive effects on society and medical systems due to the coronavirus disease 2019 (COVID-19) pandemic are substantial and far-reaching. The effect of the pandemic on the quantity and quality of pediatric traumas is unclear and has a direct bearing on how scarce hospital resources should be allocated in a pandemic situation. METHODS: A retrospective review of the trauma registry was performed for trauma activations in the years 2018 through 2020 during the months of March, April, and May. Demographic and injury specific datapoints were compared across calendar years. RESULTS: There were 111, 100, and 52 trauma activations during the study interval in 2018, 2019, and 2020, respectively. There were fewer highest severity level activations in 2020 compared to 2018 and 2019 (1 vs 5 and 9; p < 0.01). The median Injury Severity Score was 5 in 2020 compared to 4 in both 2018 and 2019 (p < 0.01). More patients went directly to the operating room in 2020 compared to prior years (21.2% vs 8% and 6.1%; p < 0.01). There were fewer discharges from the emergency department (ED) (12.1% vs 36.6% and 32.7%). No increase in the number of child abuse reports and investigations was noted. There was no difference in the proportion of blunt versus penetrating trauma between years (p = 0.57). No pedestrians were struck by automobiles in 2020 compared to 12 and 14 in 2018 and 2019. However, there were a greater proportion of injuries from falls during 2020 compared to prior years. CONCLUSIONS: There were fewer trauma activations during the peak of the COVID pandemic compared to prior years. Due to the decrease in trauma volume during the peak of the pandemic, hospital resources could potentially be reallocated toward areas of greater need. LEVEL OF EVIDENCE: IV; Retrospective cohort study using historical controls.

RESUMO

OBJECTIVE: To translate, adapt and validate the Adult Self-Report tool in Urdu language, and to establish internal consistency of its subscales. METHODS: The cross-sectional study was conducted from September 2017 to August 2018 at the National Institute of Psychology, Quaid-i-Azam University, Islamabad, Pakistan, and comprised adult stable psychiatric outpatients and non-clinical subjects from the community. After forward and backward translation of Adult Self-Report, the tool was tested on the subjects who responded on a three-point Likert scale from 'never' to 'very often'. The items were grouped under eight subscales. Data was analysed using SPSS 22. RESULTS: Of the 768 participants, 408(53%) were outpatients and 360(47%) were non-clinical subjects. The overall age range was 18-59 years. The tool was found to be effective for Pakistani sample, with root mean square error of approximation (0.03), comparative fit index (0.94) and Tucker-Lewis Index (0.94) values indicating good fit. Also, al items indicated good factor loadings (range: 0.25-0.94). Alpha values indicated that all subscales were internally consistent (range: 0.64-0.92). CONCLUSIONS: Adult Self-Report was found to be a comprehensive tool showing a good model fit for Pakistani population.

RESUMO

OBJECTIVE: To identify factors causing diagnostic and therapeutic delay in patients with rheumatoid arthritis, and to evaluate relationship of diagnostic and therapeutic delay with disease outcome. METHODS: This cross-sectional study was conducted in Rheumatology Department, Fatima Memorial Hospital, Lahore, Pakistan, from May 2018 to July 2018. In this study 102 patients fulfilling ACR/EULAR criteria 2010 were enrolled. Lag times were calculated in months: lag-1 (delay in initial medical consultation); lag-2 (delay in consulting rheumatologists); lag-3 (diagnostic delay); lag-4 (therapeutic delay). Disease activity and functional outcome were measured by DAS28, HAQ-DI respectively. Association of lag-3 and lag-4 with HAQ-DI and DAS28 was calculated by Pearson correlation. RESULTS: Median (IQR) disease duration of study group was 6(2-10) years. Initial consultations were with; orthopedic surgeon 40(39.2%), general practitioner 27(26.5%), rheumatologist 13(12.7%), medical specialists 14(13.7%). Median (IQR) lag times in months: lag-1 (delayed initial consultation): 2(0-5), lag-2 (delay in consulting rheumatologist): 30(7.7-72), lag-3 (diagnostic delay): 12(3-48), lag-4 (therapeutic delay):18(5.7-72). Factors attributed to lag-3 (diagnostic delay) and lag-4 (therapeutic delay) (p<0.05): older Age (r= 0.2), education level(r= - 0.2), initial consultation (non-rheumatologist) (r=0.2), lag-2(r=0.8), >three doctors visited before diagnosis(r=0.6). Positive anti-CCP antibodies(r=0.2) and lag-1 (delayed initial consultation) (r=1) were associated with lag-3 (diagnostic delay) only; no association was found with positive RA factor. Significant correlation (p=<0.05) of lag-3 (diagnostic delay) was found with both DAS28(r=0.2) & HAQ-DI(r=0.2). Similarly lag-4 (therapeutic delay) also correlated with both & DAS28(r=0.2) & HAQ-DI(r=0.3) (p=<0.05). CONCLUSION: Diagnostic and therapeutic delay were associated with older age, lower education and delayed consultation with rheumatologist but not with positive RA factor. Positive anti-CCP antibodies were associated with diagnostic delay only. Diagnostic and therapeutic delay led to high disease activity and poor functional outcome in RA patients.

RESUMO

Methylphenidate (MPH) is a psychostimulant, beneficial in attention deficit hyperactivity disorder (ADHD). Previously it has been shown that MPH-induced locomotor sensitization could be attenuate by buspirone co administration however the effect of chronic MPH and co-administration of MPH-buspirone on biochemical and hematological parameters are unknown. This study is designed to investigate these parameters after long term administration of MPH, Buspirone and their combination in rats. 40 male Wister rats were divided in to 4 groups, and treated with saline, MPH (2mg/kg/day), Buspirone (10mg/kg/day) and MPH-Buspirone co-administration (2mg/kg/day ±10mg/kg/day; respectively) up to six weeks. Administration of MPH significantly increase blood glucose level in saline treated control rats, however co-administration of MPH-buspirone exhibited less effect on blood glucose levels. Serum creatinine levels significantly decreased in all treated groups as compared to control but highly significant results were seen with combination treatment. Co-administration of MPH-buspirone and buspirone treated rats exhibited increased cholesterol and hemoglobin values. All treated groups showed increased values of hematocrit, MCV, MCH and MCHC compared to control group. RBCs and WBC's count were decreased in all treated groups. The platelet count rose significantly by Buspirone and MPH-buspirone administration, while MPH showed decreased platelet count. Thus, results suggested that prolong co-administration of MPH-buspirone is safe and effective for ADHD patients by preventing adverse effects not only on behavioral but also on biochemical and hematological parameter.

RESUMO

Natural oils are rich in polyunsaturated fatty acids (PUFs) like omega 3, omega 6 and other nutrients that boost physical and mental health. Traditionally these oils have been used to treat joint pain associated with several inflammatory conditions. In this study, we investigated the antioxidant and analgesic properties of the sesame oil (SO), fish oil (FO) and combination of these two oils (SO+FO). Different concentrations of the SO, FO and SO+FO combination 0.02-4mg/ml were used for assessing the free radical scavenging activity by DPPH method and the IC50 value was calculated. Acetic acid-induced abdominal writhing test, tail immersion and hot plate models were used to determined analgesic effect. Results showed that both oils were well tolerated as no signs of toxicity or death were noticed during the observational study period. SO+FO combination showed the best antioxidant properties as shown by DPPH assay. Similarly in analgesic models, SO and FO significantly reduced the number of abdominal contractions (p<0.05) however, SO+FO (1:1) exhibited highly significant results (p<0.001) in writhing reflex test. Furthermore, SO and FO both increased the reaction time on a hot plate as well as in tail flick test (p<0.05) whereas, SO+FO significantly increased reaction time (p<0.001) in hot plate and in tail flick test as compared to SO and FO single treatments. Conclusively, our results suggest that the combination of both oils (SO+FO) exhibited significant antioxidant and analgesic potential that it could be considered as one of the active combinations for relieving pain in adjunctive treatment for joint pain associated with rheumatoid arthritis.

RESUMO

Monosomy 7 (-7) and del(7q) are high-risk cytogenetic abnormalities common in myeloid malignancies. We previously reported that CUX1, a homeodomain-containing transcription factor encoded on 7q22, is frequently inactivated in myeloid neoplasms, and CUX1 myeloid tumor suppressor activity is conserved from humans to Drosophila. CUX1-inactivating mutations are recurrent in clonal hematopoiesis of indeterminate potential as well as myeloid malignancies, in which they independently carry a poor prognosis. To determine the role for CUX1 in hematopoiesis, we generated 2 short hairpin RNA-based mouse models with ∼54% (Cux1mid) or ∼12% (Cux1low) residual CUX1 protein. Cux1mid mice develop myelodysplastic syndrome (MDS) with anemia and trilineage dysplasia, whereas CUX1low mice developed MDS/myeloproliferative neoplasms and anemia. In diseased mice, restoration of CUX1 expression was sufficient to reverse the disease. CUX1 knockdown bone marrow transplant recipients exhibited a transient hematopoietic expansion, followed by a reduction of hematopoietic stem cells (HSCs), and fatal bone marrow failure, in a dose-dependent manner. RNA-sequencing after CUX1 knockdown in human CD34+ cells identified a -7/del(7q) MDS gene signature and altered differentiation, proliferative, and phosphatidylinositol 3-kinase (PI3K) signaling pathways. In functional assays, CUX1 maintained HSC quiescence and repressed proliferation. These homeostatic changes occurred in parallel with decreased expression of the PI3K inhibitor, Pik3ip1, and elevated PI3K/AKT signaling upon CUX1 knockdown. Our data support a model wherein CUX1 knockdown promotes PI3K signaling, drives HSC exit from quiescence and proliferation, and results in HSC exhaustion. Our results also demonstrate that reduction of a single 7q gene, Cux1, is sufficient to cause MDS in mice.

RESUMO

BACKGROUND: Cancer survivors face many challenges including coordinating care across multiple providers and maintaining medical records from multiple institutions. Access and utilization of online medical records could help cancer survivors manage this complexity. Here, we examined how cancer survivors differ from those without a history of cancer with regards to utilization and perception of medical records. METHODS: We conducted a cross-sectional study of 3491 respondents, from the Health Information National Trends survey 5, cycle 2. The association of medical record utilization and perceptions with cancer survivorship was assessed using survey-weighted logistic regression. RESULTS: Cancer survivors (n=593) were more likely to report that a provider maintains a computerized medical record [adjusted odds ratio (AOR)=2.05; 95% confidence (CI), 1.24-3.41] and were more likely to report confidence in medical record safeguards (AOR=1.44; 95% CI, 1.03-2.03). However, cancer survivors were no more likely to access online medical records than those without a history of cancer (AOR=1.13; 95% CI, 0.69-1.86). Cancer survivors were no more likely to report privacy concerns as a reason for not accessing online medical records, however, survivors were more likely to report a preference for speaking directly with a provider as a reason for not accessing online medical records (AOR=2.24; 95% CI, 0.99-5.05). CONCLUSIONS: Although cancer survivors are more likely to trust medical record safe guards and do not express increased concerns about online medical record privacy, a preference to speak directly with provider is a barrier of use.

RESUMO

Adults living in rural areas, compared to their urban counterparts, are at an increased risk of using tobacco-related products and mortality due to tobacco-related diseases. The harms and benefits of e-cigarette use are mixed, and similarly obscure messaging about these harms and benefits have a critical influence on e-cigarette uptake and perceptions. However, little is known about rural-urban differences in the prevalence of adult e-cigarette daily usage. Using the Health Information National Trends Survey-Food and Drug Administration (HINTS-FDA) cycles 1 and 2, we conducted weighted logistic regressions to assess rural-urban differences in the prevalence of adult e-cigarette daily usage, perceived harm, and e-cigarette information seeking behaviors. This analysis included adults aged 18 years and older in the United States (N = 4229). Both rural and urban respondents reported a similar history of e-cigarette use. Rural respondents were significantly more likely than urban respondents to trust religious organizations and leaders and tobacco companies for information about e-cigarettes. Rural and urban respondents were equally as likely to believe e-cigarettes are addictive, perceive e-cigarette use as harmful, and believe e-cigarettes are more harmful than tobacco cigarettes. Respondents were equally as likely to look for information on e-cigarettes, the health effects of e-cigarettes, and cessation; and, to seek e-cigarette information from healthcare professionals, family and friends, and health organizations and groups. Given our findings, it will be pertinent to continue to research the potential harms of e-cigarette use and develop accurate health communication messages to avoid rural-urban disparities observed for cigarette smoking-related outcomes.

RESUMO

It is unclear how resting myocardial workload, as indexed by baseline measures of rate-pressure product (RPP) and physical activity (PA), is associated with the overall risk of cancer mortality. We performed prospective analyses among 28,810 men and women from the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. We used a novel physical health (PH) composite index and categorized participants into one of four groups based on combinations from self-reported PA and RPP: 1) No PA and High RPP; 2) No PA and Low RPP; 3) Yes PA and High RPP; and 4) Yes PA and Low RPP. We examined the association between baseline PH composite and cancer mortality adjusted for potential confounders using Cox regression. A total of 1191 cancer deaths were observed over the 10-year observation period, with the majority being lung (26.87%) and gastrointestinal (21.49%) cancers. Even after controlling for sociodemographics, health behaviors, baseline comorbidity score, and medications, participants with No PA and High RPP had 71% greater risk of cancer mortality when compared to participants with PA and Low RPP (adjusted HR: 1.71, 95% CI: 1.42-2.06). These associations persisted after examining BMI, smoking, income, and gender as effect modifiers and all-cause mortality as a competing risk. Poorer physical health composite, including the novel RPP metric, was associated with a nearly 2-fold long-term risk of cancer mortality. The physical health composite has important public health implications as it provides a measure of risk beyond traditional measure of obesity and physical activity.

RESUMO

OBJECTIVE: To explore the relationship among adaptive family functioning, iImpulsivity and borderline personality disorder, and to test the mediating role of impulsivity between the other two elements. METHODS: The cross-sectional correlational study was conducted at the National Institute of Psychology, Quaid-i-Azam University, Islamabad, Pakistan, from August 17, 2015, to June 10, 2017, and comprised patients seeking psychiatric consultation. The Diagnostic and Statistical Manual of Mental Disorders-4th Edition criteria was used to assess personality disorders. Correlation and mediation analysis was carried out on those diagnosed with borderline personality disorder. Data was analysed using SPSS 21. RESULTS: Of the 408 patients assessed, 183(45%) had borderline personality disorder. Of them, 118(64.4%) were males and 65(35.5%) were females. Both impulsivity and borderline personality disorder were negatively related to adaptive family functioning (p<0.01). Significant positive relationship was found between impulsivity and border line personality disorder(p< 0.01) . CONCLUSIONS: The mediating role of impulsivity between adaptive family functioning and borderline personality disorder was established.

RESUMO

OBJECTIVE: To determine the association of systemic lupus erythematosus disease activity index (SLEDAI) score in pediatric onset SLE (p-SLE) with clinical and laboratory parameters. METHODS: This cross sectional observational study was conducted at Division of Rheumatology, Fatima Memorial Hospital, Lahore from November 2018 to January 2019. Total 23 patients diagnosed with p-SLE having onset of symptoms at ≤ 18 years of age, irrespective of their current age at presentation, of either gender, fulfilling criteria of 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria were enrolled. Patients' clinical symptoms and laboratory parameters were reviewed, SLEDAI scores were calculated. Collected Data were entered in proforma and analyzed on SPSS version 23. RESULTS: There were 91.3% females. Mean age at diagnosis was 11years ± 4years. At presentation patients had hematological involvement 69.6% followed by mucocutaneous symptoms 65.2% and renal involvement 21.6%. ANA by IFA was positive in all, while anti-ds-DNA was positive in 78.3% patients. SLEDAI score was ≥6 in 87% patients, average SLEDAI score was higher in patients with renal involvement (p=0.06). Elevated ESR (r=0.48, p=0.02), Anti-dsDNA (r=0.44, p=0.05) and low complement levels (p=0.03) were significantly positively correlated, while hemoglobin (r= -0.43, p=0.04) was negatively correlated with the SLEDAI score. CONCLUSION: In this study, patients with Lupus Nephritis had high SLEDAI scores. Elevated Anti-dsDNA titer, ESR, low complement levels and hemoglobin were significantly associated with high SLEDAI scores. We recommend that SLEDAI score should be calculated in p-SLE patients for stringent disease monitoring and treatment.

RESUMO

The novel coronavirus (nCOVID-19) has spread to endless nations and turn out to be a pandemic around the globe. Because of the developing number of affirmed cases and open public hazard owing to its high risk of infection rate, it has expected a lot of consideration from world health organizations and national health regulatory and monitoring agencies. The world is in surge to explore or discover novel treatment options and vaccine that can lead to cure. There is no proven effective treatment for nCOVID-19 however along with available antiviral therapy Chinese researchers recommended herbal treatments as effective and alternative treatments options to treat this pandemic. Herbal products are wealthy in dynamic phytochemicals, such as the terpenoids, various collection of flavonoids, sulfides, lignans constiuents, coumarins concentrates, saponins moities, polyphenolics composite, numerous alkaloids, polyines, furyl mixtures, proteins and related compounds, thiophenes and peptides groups. In this review we discussed pathogeneis, immunity and current herbal treatment strategies of nCOVID-19 to cure this world wide pandemic.
