Recent advances in nano-enabled immunomodulation for enhancing plant resilience against phytopathogens.

Plant diseases caused by microbial pathogens pose a severe threat to global food security. Although genetic modifications can improve plant resistance; however, environmentally sustainable strategies are needed to manage plant diseases. Nano-enabled immunomodulation involves using engineered nanomaterials (ENMs) to modulate the innate immune system of plants and enhance their resilience against pathogens. This emerging approach provides unique opportunities through the ability of ENMs to act as nanocarriers for delivering immunomodulatory agents, nanoprobes for monitoring plant immunity, and nanoparticles (NPs) that directly interact with plant cells to trigger immune responses. Recent studies revealed that the application of ENMs as nanoscale agrochemicals can strengthen plant immunity against biotic stress by enhancing systemic resistance pathways, modulating antioxidant defense systems, activating defense-related genetic pathways and reshaping the plant-associated microbiomes. However, key challenges remain in unraveling the complex mechanisms through which ENMs influence plant molecular networks, assessing their long-term environmental impacts, developing biodegradable formulations, and optimizing targeted delivery methods. This review provides a comprehensive investigation of the latest research on nano-enabled immunomodulation strategies, potential mechanisms of action, and highlights future perspectives to overcome existing challenges for sustainable plant disease management.

Exploring cumulative identity-based discrimination, distress, and traumatic exposure among Muslims living in the United States.

OBJECTIVE: Muslims living in the United States (MLUS), a highly heterogeneous group, experience high rates of discrimination that may cumulatively contribute to traumatic stress. This study explored whether identity-based discrimination (i.e., due to religion, gender, race) was individually and cumulatively associated with psychological distress and exposure to trauma among MLUS. METHOD: Fifty-nine MLUS completed the survey at two time points (~1 year apart). We administered measures of discrimination (at Time 1), distress (at Times 1 and 2), and trauma exposure (at Time 2). Multiple linear regressions determined whether discrimination at Time 1 was associated with traumatic exposure or distress at Time 2, after controlling for covariates. Mediation analyses determined whether the relationship between cumulative discrimination and distress at Time 2 occurred via distress at Time 1. RESULTS: MLUS who reported experiencing both religious and racial discrimination also reported greater exposure to traumatic events, after controlling for covariates. All three forms of identity-based discrimination (religion, race, gender) were individually and cumulatively (i.e., experiencing all three) associated with distress at Time 1, but not Time 2. However, the relationships between cumulative discrimination at Time 1 and distress at Time 2 were mediated by distress at Time 1. U.S.-born Muslims were particularly at risk for experiencing discrimination, distress, and traumatic exposure. CONCLUSION: Experiences of discrimination may have a cumulative impact on trauma and psychological distress among MLUS. This study underscores the need for targeted interventions that assess MLUS clients' discriminatory experiences to develop a more holistic conceptualization, better support systems, and the most effective approaches.

Deciphering fungicide resistance in Phytophthora: mechanisms, prevalence, and sustainable management approaches.

The genus Phytophthora contains more than 100 plant pathogenic species that parasitize a wide range of plants, including economically important fruits, vegetables, cereals, and forest trees, causing significant losses. Global agriculture is seriously threatened by fungicide resistance in Phytophthora species, which makes it imperative to fully comprehend the mechanisms, frequency, and non-chemical management techniques related to resistance mutations. The mechanisms behind fungicide resistance, such as target-site mutations, efflux pump overexpression, overexpression of target genes and metabolic detoxification routes for fungicides routinely used against Phytophthora species, are thoroughly examined in this review. Additionally, it assesses the frequency of resistance mutations in various Phytophthora species and geographical areas, emphasizing the rise of strains that are resistant to multiple drugs. The effectiveness of non-chemical management techniques, including biological control, host resistance, integrated pest management plans, and cultural practices, in reducing fungicide resistance is also thoroughly evaluated. The study provides important insights for future research and the development of sustainable disease management strategies to counter fungicide resistance in Phytophthora species by synthesizing current information and identifying knowledge gaps.

Impact of Sociodemographic Characteristics on the Quality of Life of Frontline Nursing Staff During COVID-19 in Saudi Arabia.

Background The COVID-19 pandemic imposed unprecedented challenges on healthcare systems worldwide. The pandemic placed frontline nursing staff working in the ICU and ER at the epicenter of this global crisis. This study aimed to assess the multifaceted impact of sociodemographic characteristics on the quality of life (QOL) of nursing staff during the pandemic. Method A cross-sectional survey was conducted to evaluate the impact of sociodemographic characteristics on the QOL of 322 frontline nurses working in the ICU and ER of five Saudi hospitals from May to July 2022. Participants completed the electronic survey questionnaire including demographic characteristics and four domains of QOL from the World Health Organization Quality of Life Questionnaire (WHOQOL-BREFF). The data was evaluated using descriptive and inferential statistics. Results Among 322 nurse participants, the majority were female (84.8%), married (64.4%), and held a bachelor's degree (92.4%). Age (above 40 years), gender (male), and marital status (married) reported a higher individual domain and overall QOL scores which shows that these characteristics have a direct influence on QOL. Years of work experience, extra working hours, and direct contact with COVID-19 patients were additional significant factors. Pearson correlation coefficients among QOL domains ranged from 0.54 to 0.91, indicating a strong interrelation among these domains. The highest transformed score was in the social domain (70.10) while the lowest score was in the psychological domain (59.20). The overall QOL mean score (SD) was 3.49(0.14) and the mean score (SD) of general health was 3.46(0.15). Conclusion The findings of this study suggest that sociodemographic and work-related factors have a complex and multifaceted impact on the QOL of nurses during the COVID-19 pandemic in Saudi Arabia. It also presents an insight into developing specific interventions to enhance nurses' resilience and well-being amidst pandemic challenges and to improve their QOL.

Genotypes, epidemiological variables and fungicides application associated with wheat leaf rust development and grain yield.

The present study was carried out at the Plant Pathology Hafizabad Research Station, the University of Layyah, during the crop seasons 2021-2022 and 2022-2023 to evaluate the response of various wheat genotypes against leaf rust severity (%), environmental conditions favourable for disease development and grain yield. Except for minimum temperature and minimum relative humidity, which had a negative association with disease development, there was a significant correlation between leaf rust severity (%) and all environmental conditions such as maximum temperature, maximum relative humidity, rainfall, and wind speed. All epidemiological variables such as maximum temperature, minimum temperature, minimum relative humidity, rainfall and wind speed significantly affect the disease progression. The disease predictive model accounted for 48-69 % variability in leaf rust severity. The model performance was evaluated using the coefficient of determination (R2 = 0.69) and RMSE, both demonstrated acceptable predictive results for leaf rust severity (%) management. Leaf rust severity (%) increased with an increase in maximum temperature (17.8-30 °C), maximum relative humidity (76.3-85 %), rainfall (2.2-10.85 mm) and wind speed 1.1-2.7 km/h and decreased with the increase of minimum temperature (7.91-16.71 °C) minimum relative humidity (47.15-56.45 %) during both rating seasons 2021-2022 and 2022-2023. The single and two applications of fungicides at the Zadok's scale 3, ZS 4.3, and ZS 5.4 stages led to a significant reduction in grain yield losses caused by leaf rust severity (%) in both the 2021-2022 and 2022-2023 crop seasons. Single and two sprays of prothioconazole, were found to be the first choice among all treatments to reduce the disease severity and increase grain production and maximum gross revenue (513.1-777.8$/ha), as compared to followed by single and two sprays of propiconazole (Progress), tebuconazole + trifloxystrobin, tebuconazole, bixafen + tebuconazole, and propiconazole (Tilt), respectively. These findings recommend the involvement of genotype resistance and weather predictors in wheat leaf rust development, along with fungicide application studies, to improve the predictability of host resistance to disease, future models, and the sustainability of disease control methods.

Formulation of sumatriptan succinate orodispersible tablets using chitosan and sodium starch glycolate for immediate migraine relief.

Migraine is one of the common neurological disease affecting around 23% of the Pakistani population. Prompt treatment is required to regain the functional ability of patients. The present study was designed to develop sumatriptan succinate orodispersible tablets that would quickly overcome acute migraine episodes using 22 full-factorial design. The chitosan and sodium starch glycolate were taken as independent variables; friability, disintegration, dispersion time and water absorption ratio as response variables. Eight trial formulations were generated by Design Expert® software. The main effect plots were used to check the interaction of formulations with response variables. All trial formulations showed good micromeritic properties in terms of angle of repose (19.59o-24.57°), Carr's index (17.08-24.90%) and Hausner's ratio (1.20-1.33). The tablets wetted quickly (17.1- 39 sec) in dispersion medium, showed higher water absorption ratio (188-341 sec) and disintegrated quickly (13-20 sec) with an excellent dissolution rate (94-99%). The main effect plots show interactions between the independent variables against most of the study responses. A 22 full-factorial model was found to be effective in studying the influence of formulation variables on response parameters. Both chitosan and sodium starch glycolate can be used in combination to fabricate an effective orodispersible formulation of sumatriptan succinate.

The central executive network moderates the relationship between posttraumatic stress symptom severity and gastrointestinal related issues.

Although most adults experience at least one traumatic event in their lifetime, a smaller proportion will go on to be clinically diagnosed with post-traumatic stress disorder (PTSD). Persons diagnosed with PTSD have a greater likelihood of developing gastrointestinal (GI) disorders. However, the extent to which subclinical levels of post-traumatic stress (PTS) correspond with the incidence of GI issues in a normative sample is unclear. Resting state fMRI, medical history, psychological survey, and anthropometric data were acquired from the Enhanced Nathan Kline Institute-Rockland Sample (n = 378; age range 18-85.6 years). The primary aim of this study was to test the main effect of subclinical PTS symptom severity on the number of endorsed GI issues. The secondary aim was to test the moderating effect of high versus low resting state functional connectivity (rsFC) of the central executive network (CEN) on the relationship between PTS symptom severity and GI issues. Trauma Symptom Checklist-40 (TSC-40) scores were positively associated with the number of endorsed GI issues (b = -0.038, SE = .009, p < .001). The interaction between TSC-40 scores and rsFC within the CEN was significant on GI issues after controlling for sociodemographic and cardiometabolic variables (b = -0.031, SE = .016, p < .05), such that above average rsFC within the CEN buffered the effect of TSC-40 scores on GI issues. Our findings of higher rsFC within the CEN moderating the magnitude of coincidence in PTS and GI symptom severity may reflect the mitigating role of executive control processes in the putative stress signaling mechanisms that contribute to gut dysbiosis.

The impact of familial involvement on dropout in a culturally informed group therapy for people diagnosed with 'schizophrenia'.

Background: Individuals with schizophrenia diagnoses are high-risk for dropout from mental health treatments, yet few studies have examined whether familial involvement in therapy impacts dropout. Methods: We examined whether familial involvement and other demographic variables predicted dropout among 101 patients enrolled in culturally informed group therapy for schizophrenia (CIGT-S), which incorporates collectivistic principles and spiritual coping into treatment. We reviewed records and conducted follow-up calls to identify reasons for dropout, and performed survival analyses to identify when dropout was likely. Results: Familial involvement was linked to greater engagement with treatment and lower dropout, signifying a mechanism for improving treatment attendance in this group. Ethnic minorities and patients with higher symptom severity demonstrated higher rates of dropout. Most patients dropped out of CIGT-S before treatment began. However, significantly lower levels of dropout were observed among those who made it to session 9 (end of the spirituality module). An inability to maintain contact with participants was the most cited reason for dropout within records, and structural reasons (e.g., moving away) were commonly cited among participants who were successfully followed-up with. Discussion: Future work may identify whether family functioning or the quality of familial relationships may predict familial involvement and, consequently, treatment attendance.

Patient-Centered Outcomes Following Prone Lateral Single-Position Approach to Same-Day Circumferential Spine Surgery.

STUDY DESIGN: Retrospective study. OBJECTIVE: Evaluate surgical characteristics and postoperative 2-year results of the PL approach to spinal fusion. SUMMARY OF BACKGROUND DATA: Prone-lateral(PL) single positioning has recently gained popularity in spine surgery due to lower blood loss and operative time but has yet to be examined for other notable outcomes, including realignment and patient-reported measures. MATERIALS AND METHODS: We included circumferential spine fusion patients with a minimum one-year follow-up. Patients were stratified into groups based on undergoing PL approach versus same-day staged (Staged). Mean comparison tests identified differences in baseline parameters. Multivariable logistic regression, controlling for age, levels fused, and Charlson Comorbidity Index were used to determine the influence of the approach on complication rates, radiographic and patient-reported outcomes up to two years. RESULTS: One hundred twenty-two patients were included of which 72(59%) were same-day staged and 50(41%) were PL. PL patients were older with lower body mass index (both P <0.05). Patients undergoing PL procedures had lower estimated blood loss and operative time (both P <0.001), along with fewer osteotomies (63% vs. 91%, P <0.001). This translated to a shorter length of stay (3.8 d vs. 4.9, P =0.041). PL procedures demonstrated better correction in both PT (4.0 vs. -0.2, P =0.033 and pelvic incidence and lumbar lordosis (-3.7 vs. 3.1, P =0.012). PL procedures were more likely to improve in GAP relative pelvic version (OR: 2.3, [1.5-8.8]; P =0.003]. PL patients suffered lesser complications during the perioperative period and greater improvement in NRS-Back (-6.0 vs. -3.3, P =0.031), with less reoperations (0.0% vs. 4.8%, P =0.040) by two years. CONCLUSIONS: Patients undergoing PL single-position procedures received less invasive procedures with better correction of pelvic compensation, as well as earlier discharge. The prone lateral cohort also demonstrated greater clinical improvement and a lower rate of reoperations by two years following spinal corrective surgery. LEVEL OF EVIDENCE: Level-III.

The Importance of Incorporating Proportional Alignment in Adult Cervical Deformity Corrections Relative to Regional and Global Alignment: Steps Toward Development of a Cervical-Specific Score.

STUDY DESIGN/SETTING: Retrospective single-center study. BACKGROUND: The global alignment and proportion score is widely used in adult spinal deformity surgery. However, it is not specific to the parameters used in adult cervical deformity (ACD). PURPOSE: Create a cervicothoracic alignment and proportion (CAP) score in patients with operative ACD. METHODS: Patients with ACD with 2-year data were included. Parameters consisted of relative McGregor's Slope [RMGS = (MGS × 1.5)/0.9], relative cervical lordosis [RCL = CL - thoracic kyphosis (TK)], Cervical Lordosis Distribution Index (CLDI = C2 - Apex × 100/C2 - T2), relative pelvic version (RPV = sacral slope - pelvic incidence × 0.59 + 9), and a frailty factor (greater than 0.33). Cutoff points were chosen where the cross-tabulation of parameter subgroups reached a maximal rate of meeting the Optimal Outcome. The optimal outcome was defined as meeting Good Clinical Outcome criteria without the occurrence of distal junctional failure (DJF) or reoperation. CAP was scored between 0 and 13 and categorized accordingly: ≤3 (proportioned), 4-6 (moderately disproportioned), >6 (severely disproportioned). Multivariable logistic regression analysis determined the relationship between CAP categories, overall score, and development of distal junctional kyphosis (DJK), DJF, reoperation, and Optimal Outcome by 2 years. RESULTS: One hundred five patients with operative ACD were included. Assessment of the 3-month CAP score found a mean of 5.2/13 possible points. 22.7% of patients were proportioned, 49.5% moderately disproportioned, and 27.8% severely disproportioned. DJK occurred in 34.5% and DJF in 8.7%, 20.0% underwent reoperation, and 55.7% achieved Optimal Outcome. Patients severely disproportioned in CAP had higher odds of DJK [OR: 6.0 (2.1-17.7); P =0.001], DJF [OR: 9.7 (1.8-51.8); P =0.008], reoperation [OR: 3.3 (1.9-10.6); P =0.011], and lower odds of meeting the optimal outcome [OR: 0.3 (0.1-0.7); P =0.007] by 2 years, while proportioned patients suffered zero occurrences of DJK or DJF. CONCLUSION: The regional alignment and proportion score is a method of analyzing the cervical spine relative to global alignment and demonstrates the importance of maintaining horizontal gaze, while also matching overall cervical and thoracolumbar alignment to limit complications and maximize clinical improvement.

Factors Influencing Maintenance of Alignment and Functional Improvement Following Adult Spinal Deformity Surgery: A 3-Year Outcome Analysis.

STUDY DESIGN: This was a retrospective review. OBJECTIVE: To assess the factors contributing to durability of surgical results following adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND: Factors contributing to the long-term sustainability of ASD correction are currently undefined. MATERIALS AND METHODS: Operative ASD patients with preoperatively (baseline) and 3-year postoperatively radiographic/health-related quality of life data were included. At 1 and 3 years postoperatively, a favorable outcome was defined as meeting at least three of four criteria: (1) no proximal junctional failure or mechanical failure with reoperation, (2) best clinical outcome (BCO) for Scoliosis Research Society (SRS) (≥4.5) or Oswestry Disability Index (ODI) (<15), (3) improving in at least one SRS-Schwab modifier, and (4) not worsening in any SRS-Schwab modifier. A robust surgical result was defined as having a favorable outcome at both 1 and 3 years. Predictors of robust outcomes were identified using multivariable regression analysis with conditional inference tree for continuous variables. RESULTS: We included 157 ASD patients in this analysis. At 1 year postoperatively, 62 patients (39.5%) met the BCO definition for ODI and 33 (21.0%) met the BCO for SRS. At 3 years, 58 patients (36.9%) had BCO for ODI and 29 (18.5%) for SRS. Ninety-five patients (60.5%) were identified as having a favorable outcome at 1 year postoperatively. At 3 years, 85 patients (54.1%) had a favorable outcome. Seventy-eight patients (49.7%) met criteria for a durable surgical result. Multivariable adjusted analysis identified the following independent predictors of surgical durability: surgical invasiveness >65, being fused to S1/pelvis, baseline to 6-week pelvic incidence and lumbar lordosis difference >13.9°, and having a proportional Global Alignment and Proportion score at 6 weeks. CONCLUSIONS: Nearly 50% of the ASD cohort demonstrated good surgical durability, with favorable radiographic alignment and functional status maintained up to 3 years. Surgical durability was more likely in patients whose reconstruction was fused to the pelvis and addressed lumbopelvic mismatch with adequate surgical invasiveness to achieve full alignment correction.

A 4-session written emotional disclosure intervention lowers 6-month sympathoadrenal urinary output in persons living with HIV.

OBJECTIVE: We previously reported that a brief guided written emotional disclosure (WED) intervention resulted in significant reductions in post-traumatic stress disorder (PTSD) symptomology in women, but not men, living with HIV. Levels of 24-hour urinary output of epinephrine (E) and norepinephrine (NE) are shown to be elevated in persons diagnosed with PTSD. The current study tested whether there was an effect for the 4-week WED intervention on 6-month change in urinary E and NE output amongst persons living with HIV. METHOD: Fourteen women and 11 men living with HIV randomized to four 30-min expressive writing sessions of either trauma writing or daily events writing in the parent trial were included based upon collection of urine specimens at baseline, 1-, and 6-months after the intervention. Total volume (µg) and concentration (µg/ml) of urinary E and NE were derived from the specimens as study outcomes. RESULTS: Four repeated measures analyses of covariance (ANCOVA) were performed to evaluate study outcomes using trauma- versus daily-writing as the between-subject factors and collection time point as the within-subject factor, controlling for age and sex. A group x time interaction was observed wherein the trauma writing treatment group showed a significantly greater decrease in total urinary output, F(2, 46) = 4.03, p = .03, and concentration, F(2, 46) = 4.74, p = .01 of epinepherine. Post-hoc analyses revealed the interaction effect for the total, F(2, 22) = 4.82, p = .03, and concentration, F(2, 22) = 7.57, p = .005, of urinary E output over 6-months was significant for women. Interactions were not observed in urinary NE output. CONCLUSIONS: Significant reductions in the total output and concentration of urinary E were found up to 6-months following initiation of a 4-session guided written emotional disclosure intervention. Profiles of sympathoadrenal activity and response to expressive writing differ between men and women living with HIV. Futher research is need to characterize the putative pathways linking sympathoadrenal response to upstream neurobiological function and downstream inflammatory-immune status in women living with HIV and PTSD.

COVID-19 booster dose acceptance, hesitancy and concerns among the elderly population: A cross-sectional study.

INTRODUCTION: The COVID-19 pandemic that originated in Wuhan, China in December 2019 results in respiratory and gastrointestinal infections. Elderly patients are at high risk. Preventive measures like avoiding contact with COVID-19 patients and wearing N95 masks can contribute to reducing the risk of infection, but vaccination remains crucial. METHODOLOGY: A cross-sectional survey-based study was conducted among the elderly population (≥ 50 years) in Pakistan. A 16-items questionnaire explored the socio-demographic profile of the participants, including questions about their age, gender, etc. The other sections included questions regarding vaccine registration, vaccine acceptance, and hesitation and fears towards vaccines. The items were developed to collect the data on the basis of the Likert scale. RESULTS: There was a total of 3059 respondents. The majority of the participants (n = 2726, 89.1%) were aged below 70 years, while 10.9% (n = 333) were aged above 70 years. Many participants (47.1%) expressed their concerns about the efficacy of COVID-19 vaccine booster dose. Despite their willingness to vaccinate with the cOVID-19 vaccine, 24.7% female participants expressed concerns related to the safety of the vaccine. Among all the respondents, 23.1% participants had no concerns about the cOVID-19 vaccine booster dose. The study identified a reluctance and lack of confidence in the efficiency of the COVID-19 booster dose. CONCLUSIONS: The alarming situation is rigidity towards vaccination among the elderly population. Necessary measures must be taken by the health department of Pakistan to manage this reluctant behavior and increase confidence on the efficiency of the COVID-19 booster dose.

Cardiovascular sex-differences: insights via physiology-based modeling and potential for noninvasive sensing via ballistocardiography.

In this study, anatomical and functional differences between men and women in their cardiovascular systems and how these differences manifest in blood circulation are theoretically and experimentally investigated. A validated mathematical model of the cardiovascular system is used as a virtual laboratory to simulate and compare multiple scenarios where parameters associated with sex differences are varied. Cardiovascular model parameters related with women's faster heart rate, stronger ventricular contractility, and smaller blood vessels are used as inputs to quantify the impact (i) on the distribution of blood volume through the cardiovascular system, (ii) on the cardiovascular indexes describing the coupling between ventricles and arteries, and (iii) on the ballistocardiogram (BCG) signal. The model-predicted outputs are found to be consistent with published clinical data. Model simulations suggest that the balance between the contractile function of the left ventricle and the load opposed by the arterial circulation attains similar levels in females and males, but is achieved through different combinations of factors. Additionally, we examine the potential of using the BCG waveform, which is directly related to cardiovascular volumes, as a noninvasive method for monitoring cardiovascular function. Our findings provide valuable insights into the underlying mechanisms of cardiovascular sex differences and may help facilitate the development of effective noninvasive cardiovascular monitoring methods for early diagnosis and prevention of cardiovascular disease in both women and men.

Simultaneous adsorption of methylene blue and amoxicillin by starch-impregnated MgAl layered double hydroxide: Parametric optimization, isothermal studies and thermo-kinetic analysis.

Textile and pharmaceutical effluents contain significant amounts of dyes and antibiotics, which pose a serious threat to the ecosystem when discharged directly. Therefore, they should be treated by facile treatment techniques using low-cost materials. Layered double hydroxide (LDH) and its hybrids have emerged as robust and economic adsorbents for water treatment. Herein, magnesium/aluminum LDH and its starch-based composite were synthesized by a co-precipitation technique. The physicochemical features of the developed adsorbents were thoroughly characterized using various analytical tools. The developed materials were tested for the eradication of methylene blue (MB) and amoxicillin (AMX) in batch mode adsorption by varying operating conditions. Adsorption performance depends on the solution's pH. Under optimum adsorption conditions of pH 11, adsorbent dosage of 50 mg/L, and treatment time of 120 min, starch-impregnated MgAl-LDH exhibited maximum MB and AMX adsorption capacities of 114.94 and 48.08 mg/g, respectively. The adsorption mechanism states that hydrogen bonds and weak van der Waals forces are responsible for the removal of pollutants by the developed materials. Moreover, equilibrium and kinetic studies revealed that the removal of dye and antibiotic followed the Freundlich and Langmuir models with the pseudo-second-order reaction kinetics, respectively. The spent adsorbents were regenerated using 0.1 M HCl (for MB) and methanol (for AMX) eluent, and reusability studies ensured that the developed adsorbents retained their performance for up to four consecutive adsorption/desorption cycles. MgAl-LDH and its starch-based hybrid could thus be used to effectively remove organic contaminants from wastewater streams on a commercial scale.

Frequency of Private Prayer Predicts Survival Over 6 Years in a Nationwide U.S. Sample of Individuals with a Chronic Illness.

Prayer is central to religious/spiritual life, and there are many claims for its effectiveness. However, few studies have examined whether frequency of prayer predicts survival in people with a chronic illness. This study follows a nationwide United States sample of people with a chronic illness (N = 1931) from 2014 to 2020. Those who prayed on a daily basis or more were significantly more likely to survive over 6 years (Hazard Ratio = 1.48; 95% Confidence Intervals: 1.08-2.03) compared with those who prayed less often, after controlling for biomedical variables (age, medical symptoms), sociodemographics (sex, race, and education), psychosocial variables (depression, social support), and health behaviors (alcohol use, smoking, exercise, and body mass index/weight).

Participatory action research to co-design a culturally appropriate COVID-19 risk communication and community engagement strategy in rural Pakistan.

Background: Community engagement has shown to be fundamental component of the response to previous disease outbreaks. This study aimed co-design and implement a culturally appropriate COVID-19 risk communication and community engagement strategy with a resource-poor rural community in Northwest Pakistan. Methods: Participatory Action Research (PAR) was conducted from January 2021 to March 2022. Five PAR meetings took place with community members (n = 30) to: (1) explore how the COVID-19 pandemic impacted on the community; (2) identify challenges to limit the spread of the virus; (3) identify and implement solutions to these challenges; and (4) highlight the enablers, challenges and knowledge of the cultural context needed to optimize safety during emergencies. Focus group discussions (N = 6) with community members not involved in the PAR meetings (N = 50) and children of the community (N = 26) were conducted following the PAR meetings. Thematic analysis of the PAR and focus group data was conducted. Results: Delivery of messages on how to keep families safe, provision of personal protective equipment and improved water systems were part of the strategies taken by the community to create awareness and reduce the spread of COVID-19. Nine themes were identified: Attitudes to the pandemic: From skepticism to acceptance, Changing attitudes about vaccination: rumors and trust, COVID-19 and Faith, Social impact of the pandemic, Access to water, Resource mobilization: personal protective equipment, Spaces where collaborative effort can bring to solutions, Agents of change, and Empowerment of women. Discussion: The participatory approach of this research allowed understanding of the challenges faced by the community to engage in behavior change strategies to reduce the spread of COVID-19 and enabled the community to find sustainable solutions. Engagement with the community empowered men and women to be agents of change and promoted necessary precautionary actions to reduce the risk of infection within their community. Conclusion: Participatory approach highlighted the importance of engaging with and integrating to local culture and values to overcome challenges such as gender imbalance and distrust. Findings of this study are relevant to others working in diverse cultural settings in similar crises events regardless of particular cultural variations.

Natural history of adult spinal deformity: how do patients with suboptimal surgical outcomes fare relative to nonoperative counterparts?

OBJECTIVE: Management of adult spinal deformity (ASD) has increasingly favored operative intervention; however, the incidence of complications and reoperations is high, and patients may fail to achieve idealized postsurgical results. This study compared health-related quality of life (HRQOL) metrics between patients with suboptimal surgical outcomes and those who underwent nonoperative management as a proxy for the natural history (NH) of ASD. METHODS: ASD patients with 2-year data were included. Patients who were offered surgery but declined were considered nonoperative (i.e., NH) patients. Operative patients with suboptimal outcome (SOp)-defined as any reoperation, major complication, or ≥ 2 severe Scoliosis Research Society (SRS)-Schwab modifiers at follow-up-were selected for comparison. Propensity score matching (PSM) on the basis of baseline age, deformity, SRS-22 Total, and Charlson Comorbidity Index score was used to match the groups. ANCOVA and stepwise logistic regression analysis were used to assess outcomes between groups at 2 years. RESULTS: In total, 441 patients were included (267 SOp and 174 NH patients). After PSM, 142 patients remained (71 SOp 71 and 71 NH patients). At baseline, the SOp and NH groups had similar demographic characteristics, HRQOL, and deformity (all p > 0.05). At 2 years, ANCOVA determined that NH patients had worse deformity as measured with sagittal vertical axis (36.7 mm vs 21.3 mm, p = 0.025), mismatch between pelvic incidence and lumbar lordosis (11.9° vs 2.9°, p < 0.001), and pelvic tilt (PT) (23.1° vs 20.7°, p = 0.019). The adjusted regression analysis found that SOp patients had higher odds of reaching the minimal clinically important differences in Oswestry Disability Index score (OR [95% CI] 4.5 [1.7-11.5], p = 0.002), SRS-22 Activity (OR [95% CI] 3.2 [1.5-6.8], p = 0.002), SRS-22 Pain (OR [95% CI] 2.8 [1.4-5.9], p = 0.005), and SRS-22 Total (OR [95% CI] 11.0 [3.5-34.4], p < 0.001). CONCLUSIONS: Operative patients with SOp still experience greater improvements in deformity and HRQOL relative to the progressive radiographic and functional deterioration associated with the NH of ASD. The NH of nonoperative management should be accounted for when weighing the risks and benefits of operative intervention for ASD.

Long-term Morbidity in Patients After Surgical Correction of Adult Spinal Deformity: Results From a Cohort With Minimum 5-year Follow-up.

STUDY DESIGN: Retrospective. OBJECTIVE: The objective of this study is to describe the rate of postoperative morbidity before and after two-year (2Y) follow-up for patients undergoing surgical correction of adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA: Advances in modern surgical techniques for deformity surgery have shown promising short-term clinical results. However, the permanence of radiographic correction, mechanical complications, and revision surgery in ASD surgery remains a clinical challenge. Little information exists on the incidence of long-term morbidity beyond the acute postoperative window. METHODS: ASD patients with complete baseline and five-year (5Y) health-related quality of life and radiographic data were included. The rates of adverse events, including proximal junctional kyphosis (PJK), proximal junctional failure (PJF), and reoperations up to 5Y were documented. Primary and revision surgeries were compared. We used logistic regression analysis to adjust for demographic and surgical confounders. RESULTS: Of 118 patients eligible for 5Y follow-up, 99(83.9%) had complete follow-up data. The majority were female (83%), mean age 54.1 years and 10.4 levels fused and 14 undergoing three-column osteotomy. Thirty-three patients had a prior fusion and 66 were primary cases. By 5Y postop, the cohort had an adverse event rate of 70.7% with 25 (25.3%) sustaining a major complication and 26 (26.3%) receiving reoperation. Thirty-eight (38.4%) developed PJK by 5Y and 3 (4.0%) developed PJF. The cohort had a significantly higher rate of complications (63.6% vs. 19.2%), PJK (34.3% vs. 4.0%), and reoperations (21.2% vs. 5.1%) before 2Y, all P <0.01. The most common complications beyond 2Y were mechanical complications. CONCLUSIONS: Although the incidence of adverse events was high before 2Y, there was a substantial reduction in longer follow-up indicating complications after 2Y are less common. Complications beyond 2Y consisted mostly of mechanical issues.
