RESUMO

PURPOSE: The aim of this study is to investigate the extent to which organizational justice (OJ) mediates between responsible leadership (RL) and employee turnover intention (TI). DESIGN/METHODOLOGY/APPROACH: Both online and offline questionnaire was used to collect the data from 387 Indian health-care employees, and the data were analyzed using partial least squares structural equation modeling (PLS-SEM) with the help of SmartPLS 4. FINDINGS: The study's findings demonstrated a significant positive association between RL and OJ and a negative association between OJ and employee TI. Furthermore, results also confirmed the mediating role of OJ between RI and TI. RESEARCH LIMITATIONS/IMPLICATIONS: The generalizability of the study's data collection is limited because it is based on the responses of Indian health-care sector employees to an online and offline survey. The authors propose that the health-care sector uses RL as an approach that takes a broad view of the parties with a stake and focuses on creating fairness in acts and justice at the workplace to address the major issue of employee turnover. ORIGINALITY/VALUE: This study expanded on previous research by demonstrating that the influence of responsible leadership on employee TI is mediated by OJ in the context of India's health-care sector. It also contributes to the literature regarding RI, OJ and TI. The study also enriched the body of knowledge about using the PLS-SEM approach to predict employee TI.

RESUMO

Rickettsia prowazekii is an intracellular, obligate, gram-negative coccobacillus responsible for epidemic typhus. Usually, the infected body louse or its excrement when rubbed into the skin abrasions transmits the disease. The infection with R. prowazekii causes the highest death rate (> 20% without antibiotic treatment and now 1-7%), followed by epidemic typhus, which often manifests in unsanitary conditions (up to 15-30%). Conventionally, vaccine design has required pathogen growth and both assays (in vivo and in vitro), which are costly and time-consuming. However, advancements in bioinformatics and computational biology have accelerated the development of effective vaccine designs, reducing the need for traditional, time-consuming laboratory experiments. Subtractive genomics and reverse vaccinology have become prominent computational methods for vaccine model construction. Therefore, the RefSeq sequence of Rickettsia prowazekii (strain Madrid E) (Proteome ID: UP000002480) was subjected to subtractive genomic analysis, including factors such as non-similarity to host proteome, essentiality, subcellular localization, antigenicity, non-allergenicity, and stability. Based on these parameters, the vaccine design process selected specific proteins such as outer membrane protein R (O05971_RICPR PETR; OmpR). Eventually, the OmpR was subjected to a reverse vaccinology approach that included molecular docking, immunological simulation, and the discovery of B-cell epitopes and MHC-I and MHC-II epitopes. Consequently, a chimeric or multi-epitope-based vaccine was proposed by selecting the V11 vaccine and its 3D structure modeling along with molecular docking against TLR and HLA protein, in silico simulation, and vector designing. The obtained results from this investigation resulted in a new perception of inhibitory ways against Rickettsia prowazekii by instigating novel immunogenic targets. To further assess the efficacy and protective ability of the newly designed V11 vaccine against Rickettsia prowazekii infections, additional evaluation such as in vitro or in vivo immunoassays is recommended.

RESUMO

Delirium, a common and serious disorder in older hospitalized patients, remains underrecognized. While several delirium predictive models have been developed, only a handful have focused on electronic health record (EHR) data. This prospective cohort study of older inpatients (≥65 years old) aimed to determine if variables within our health system's EHR could be used to identify delirium among hospitalized patients at the bedside. Trained researchers screened daily for delirium using the 3-minute diagnostic Confusion Assessment Method (3D-CAM). Patient demographic and clinical variables were extracted from the EHR. Among 408 participants, mean age was 75 years, 60.8% were female, and 82.6% were Black. Overall rate of delirium was 16.7%. Patients with delirium were older and more likely to have an infection diagnosis, prior dementia, higher Charlson comorbidity severity of illness score, lower Braden Scale score, and higher Morse Fall Scale score in the EHR (P<0.01 for all). On multivariable analysis, a prior diagnosis of dementia (odds ratio: 5.0, 95% CI: 2.5-10.3) and a Braden score of <18 (odds ratio: 2.8, 95% CI: 1.5-5.1) remained significantly associated with delirium among hospitalized patients. Further research in the development of an automated delirium prediction model is needed.

RESUMO

Plants generally secrete secondary metabolites in response to stress. These secondary metabolites are very useful for humankind as they possess a wide range of therapeutic activities. Secondary metabolites produced by plants include alkaloids, flavonoids, terpenoids, and steroids. Flavonoids are one of the classes of secondary metabolites of plants found mainly in edible plant parts such as fruits, vegetables, stems, grains, and bark. They are synthesized by the phenylpropanoid pathway. Flavonoids possess antibacterial, antiviral, antioxidant, anti-inflammatory, antimutagenic, and anticarcinogenic properties. Due to their various therapeutic applications, various pharmaceutical companies have exploited different plants for the production of flavonoids. To overcome this situation, various biotechnological strategies have been incorporated to improve the production of different types of flavonoids. In this review, we have highlighted the various types of flavonoids, their biosynthesis, properties, and different strategies to enhance the production of flavonoids.

RESUMO

Environment contamination is a colossal worriment across the world, owing to its detrimental and negative impact on health and ecological systems. Dyes are one of the synthetic organic chemicals that are utilised in a variety of fields, including textiles. As a result, throughout one's production and subsequently in fibre colouring, these are becoming frequent industry-contributed contaminants. Increasing globalisation of international market has presented a problem to textile sector in terms of consistency and production. Textile processors' primary concern, as the highly competitive environment and environmental standards grow more severe is about being mindful of the grade of goods and even non-toxicity of their production processes. There seems to be an immediate necessity to look for methods and technologies which are useful in removing dye colours. Even though each has benefits and weaknesses, many physical, chemical, and biological approaches were explored and used with the application being dependent on the effluent properties, technical feasibility, and cost. Several remediation technologies are already developed, but they seem to be ineffective at removing dyes completely. There is a fast growth of nanoparticles applications in the past few years which has opened up newer, innovating, highly efficient, and low-cost dyes remediation systems. Nanomaterials with large surface areas change surface characteristics and distinctive electron conducting capabilities which make them ideal candidate for the treatment of wastewater that contains dyes. In this review, we have highlighted not only the role of nanotechnology in dye remediation processes but also different types of nanomaterials that can be used for the remediation of dyes.

RESUMO

OBJECTIVE: The study aimed to assess the prevalence of newly prescribed antipsychotic/benzodiazepine medication, as well as 30-day readmissions, among Hospital Elder Life Program (HELP)-enrolled patients. DESIGN: Retrospective case-control study. SETTING: HELP intervention took place in eight hospital units. The standard care group was selected from eight additional hospital units. PARTICIPANTS: Hospitalized patients, aged 65 years and older, enrolled in HELP during between January 1, 2017 to December 31, 2018 were included in the HELP cohort. Patients hospitalized in eight additional units during the same time frame were part of the standard care group. MEASUREMENTS: Antipsychotic/benzodiazepine medications were pulled from the electronic health record. History of chronic mental illnesses were classified by ICD10 codes. Basic descriptive statistics were used to analyze patient characteristics and comorbidities. Chi-squared and t-tests were performed to detect statistical differences as appropriate. RESULTS: There were 1411 patients in the HELP group and 10,807 patients in the standard care group. The HELP group was likely to be older, female and to have a shorten length of stay (all p ≤ 0.02). Our study demonstrated that approximately 8.9% (n = 125) of patients enrolled in HELP received an order for antipsychotics during their hospital admission, while 31.5% (n = 3400) from the standard care group (p < 0.001). The difference in benzodiazepine prescription in patients enrolled in HELP was also less when comparing the two groups (22.8% HELP vs 25.6% standard care; p = 0.02). CONCLUSIONS: Patients enrolled in the HELP group were less likely to receive a prescription for antipsychotics or benzodiazepines. The majority of patients enrolled in HELP were discharged to a more independent environment (home or assisted living) and there was a relatively low 30-day readmission rate among HELP patients.

RESUMO

Quantitative descriptions of the morphology and structure of peripheral nerves is central in the development of bioelectronic devices interfacing the nerves. While histological procedures and microscopy techniques yield high-resolution detailed images of individual axons, automated methods to extract relevant information at the single-axon level are not widely available. We implemented a segmentation algorithm that allows for subsequent feature extraction in immunohistochemistry (IHC) images of peripheral nerves at the single fiber scale. These features include short and long cross-sectional diameters, area, perimeter, thickness of surrounding myelin and polar coordinates of single axons within a nerve or nerve fascicle. We evaluated the performance of our algorithm using manually annotated IHC images of 27 fascicles of the swine cervical vagus; the accuracy of single-axon detection was 82%, and of the classification of fiber myelination was 89%.

RESUMO

For physiological and biochemical studies, it is considered essential to have knowledge about the accumulation of mineral elements in plants and their distribution in different parts of the fruit and these data being essential for geographical origins of different food commodities. In the age of food industry globalization, the origin of food is essential to know for human health protection, to stimulate fine agronomic actions and to bar the use of toxic materials to stimulate plant's growth. This research work was formulated to assess the essential trace and toxic elements in Guar (Cyamopsis tetragonoloba) and guar gum cultivated in semi-arid regions of Sindh, Pakistan. For pretreatment of the guar samples, microwave-assisted acid digestion procedure (MAD) was developed for the elemental analysis in the guar samples. The validity of designed method was checked by using certified reference samples of BCR 189 whole meal flour. The digested specimens were analyzed by flame and graphite furnace atomic absorption spectrophotometry. The concentration of essential trace and toxic elements was found to be within the international level. In addition, human health Risk assessment was accessed by measuring daily intake of all understudy minerals, which was within permissible exposure limit set by USEPA & Health Canada. The Target Hazard Quotient (THQs) of guar and its gum were generally less than 1, as per USEPA; owing to these facts, food grade guar gum can be produced from guar cultivated in Thar, Pakistan.

RESUMO

BACKGROUND: Each hospital day of delirium incurs greater healthcare costs, higher levels of care, greater staff burden, and higher complication rates. Accordingly, administrators are incentivized to identify models of care that reduce delirium rates and associated costs. PURPOSE: We present a systematic review and meta-analysis of delirium prevention models of care. DATA SOURCES: Ovid MEDLINE, CINAHL, Cochrane Database of Systematic Reviews, EMBASE, and PsycINFO. STUDY SELECTION: Eligible models of care were defined as provider-oriented interventions involving revision of professional roles, multidisciplinary teams, and service integration. Included studies implemented multidomain, multicomponent interventions, used a validated delirium instrument, and enrolled a control group to evaluate efficacy or effectiveness. DATA EXTRACTION: We extracted data on study design; Population, model of care, outcomes, and results. DATA SYNTHESIS: A total of 15 studies were included. All but two studies reported reduction in delirium or its duration, and 11 studies reported statistically significant improvements. Using random effects models, the pooled odds ratios of delirium incidence were 0.56 (95% CI: 0.37-0.85) from three randomized controlled trials, 0.63 (95% CI 0.37-1.07) from four pre-post intervention studies, and 0.79 (95% CI: 0.46-1.37) from three additional nonrandomized studies. CONCLUSIONS: Several models of care can prevent delirium. In general, higher quality studies were more likely to demonstrate statistical significance of an effect. The diverse models of care included here explored interventions adapted to specific care settings, especially by addressing setting-specific delirium risk factors. These care models illustrate a range of promising strategies that deserve growing recognition, refinement, and implementation.

RESUMO

OBJECTIVE: A short pre-hospital delay, from the onset of symptoms to rapid initiation of reperfusion therapy, is a crucial factor in determining prognosis of myocardial infarction (MI). The purpose of this study was to evaluate symptoms and presentation delay times in MI patients with and without diabetes. METHODS: This cross-sectional study was conducted in 3 tertiary care hospitals of Pakistan over a period of 6 months. The study sample consisted of 280 consenting individuals diagnosed with ST-elevation MI (STEMI) or Non-ST elevation MI (NSTEMI), out of which 130 were diabetic and 150 were non-diabetic. Data was collected using a standardized questionnaire, investigating MI symptoms along with causes and duration of pre-hospital delay within 72hours of admission. RESULTS: No significant difference was found in the intensity of chest pain between diabetics and non-diabetics. Atypical symptoms of MI such as anxiety (p<0.001), cold sweats (p=0.034) and epigastric pain (p=0.017) were more frequently reported in diabetics. MI patients with diabetes had a significantly longer presentation delay time with 75% of the patients presenting after elapse of 3h. Only a few patients reported to the hospital within an hour of onset of symptoms (n=23, 8.2%), out of which majority were non-diabetics (n=18). A majority of patients (n=146, 52%) in both groups did not use emergency medical services. CONCLUSION: This study provides an incentive for further research, aiming to reduce pre hospital delay along with investigating the effectiveness of emergency medical services.

RESUMO

Donors after brain death (DBD) have been the major source of organ donation due to good perfusion of the organs. However, owing to the mismatch in demand and supply of the organ donors and recipients, donors after circulatory death (DCDDs) has increased recently all over the world. Kidneys, liver, and lungs are being used for transplantation from DCDDs. Recently, heart transplantation from DCDDs has been started, which is under the firestorm of scrutiny by the ethicists. The ethical dilemma revolves around the question whether the donors are actually dead when they are declared dead by cardiocirculatory death criteria for organ procurement. The subsequent literature review addresses all the perspectives by differentiating between the donation methods known as DBDs and DCDDs, explaining the implications of the dead-donor rule on the organ donation pool, and categorizing the determinants of death leading to separation of the arguments under the two methods of donations.

RESUMO

Delirium (acute confusion) is a serious, common health condition, and it predicts poor outcomes, including greater rates of mortality, institutionalization, prolonged hospitalization, and cognitive impairment. Expedient diagnosis and management are critical to address modifiable delirium causes and improve both quality of care and outcomes. Moreover, more than a third of delirium is preventable. Despite the clear significance of delirium and our increasingly sophisticated understanding of the condition, the gap between evidence and practice persists. The authors provide an educational review of 10 prevalent misconceptions of delirium pertaining to recognition, etiology, natural history, and best management. The authors respond to each with best evidence. Several themes emerge, chief among which is that casual observation is seldom sufficient to detect delirium. Use of open-ended questions, regular neurocognitive testing, and validated delirium screening instruments will aid in accurately identifying cases of delirium. Delirium is typically multifactorial, with several physiological and/or pharmacological contributors. Because of its multidetermined nature and its relationship with cognitive vulnerability, delirium can persist for days to months after acute causes have resolved. Furthermore, patients often have long-term cognitive impairment after delirium rather than returning to their predelirium cognitive baseline. Finally, nonpharmacological management of delirium is first-line, both for prevention and treatment. Psychotropic drugs such as neuroleptics are not recommended for routine use in delirium. They are best reserved for treating dangerous or distressing symptoms, including severe agitation, psychosis, or emotional lability. Challenging these 10 misconceptions stands to improve patient care, quality of life, and clinical outcomes substantially.

RESUMO

PURPOSE: The purpose of this systematic review is to summarize the reported risk prediction models and identify the most prevalent factors for incident delirium in older inpatient populations (age ≥ 65 years). In the future, these risk factors could be used to develop a delirium risk prediction model in the electronic health record that can be used by the Hospital Elder Life Program to reduce the incidence of delirium. METHODS: A medical librarian customized and conducted a search strategy for all published articles on delirium prediction models using an array of electronic databases and specific inclusion and exclusion criteria. Then, a geriatrician and two research associates assessed the quality of the selected studies using the Newcastle-Ottawa Scale (NOS). RESULTS: A total of 4,351 articles were identified from initial literature search. After review, data were extracted from 12 studies. The quality of these studies was assessed using NOS and ranged from 4 to 8. The most common risk factors reported were dementia, decreased functional status, high blood urea nitrogen-to-creatinine ratio, infection and severe illness. CONCLUSIONS: The most prevalent factors associated with incidence of delirium in hospitalized older patients identified by this systematic review could be used to develop an electronic health record-generated risk prediction model to identify inpatients at risk of developing delirium.

RESUMO

INTRODUCTION: Health care workers need to consider the culture and ethnic preferences prevalent in the Hmong community in order to provide optimal care. We describe an older Hmong man to illustrate the challenges faced and competencies needed by primary care. CASE PRESENTATION: An 80-year-old non-English speaking Hmong man with diabetes, nerve sheath tumor, and hypertension presented to the outpatient clinic with his grandson complaining of sleep problems. He had had 2 vivid recurring dreams during the previous few months. Memory assessment was significant for dementia. DISCUSSION: This case addresses the complexity in taking care of a non-English speaking Hmong older man who has memory loss, trauma in adulthood, multiple caregivers, and sleep problems. CONCLUSIONS: A careful history from patient and family to get to know their cultural preferences and attitudes was helpful. Identification of the primary caregiver was critical in providing care.

RESUMO

Background. We present a rare case of bilateral moyamoya disease presenting as multiple strokes and neurological deficits, treated with the neurosurgical procedure, encephaloduroarteriosynangiosis (EDAS), in a 2-year-old male Pakistani minor. A positive outcome was achieved and the patient recovered fully. Case Summary. Our patient presented with a history of seizures and multiple episodes of hemiparesis (on and off weakness) at the age of 2 years. He had a delayed speech development and could not speak more than a few words. He had a slight slurring of speech too. He was diagnosed with bilateral moyamoya disease on Computed Tomography Angiography (CTA). Bilateral EDAS was done in the same year, after which his symptoms improved and patient had moderate functional recovery. Conclusion. A rare disease, moyamoya has been left unexplored in Pakistan; physicians and surgeons when dealing with cases in the pediatric population presenting with symptoms of stroke, signs of generalized weakness, and seizures should consider moyamoya disease as a possibility. Furthermore, this case demonstrates the effectiveness of EDAS procedure for the treatment of moyamoya disease.
