RESUMEN

Background: Although many studies worldwide have reported on violence against health care workers, there is a lack of homogeneous data for understanding the current state of the issue. Conducting a global survey required a robust team organisation structure, unique dissemination strategies, and continual networking to maintain and propagate the pool of survey collaborators and responders. Here we aimed to describe the strategies that helped us carry out a global survey-based study, the lessons learned, and provide a practical roadmap for future large-scale cross-sectional studies. Methods: We conducted this cross-sectional survey-based study from 6 June to 9 August 2022, basing it on the 'Hub and Spoke' model, with a single core team and subgroups in different regions managed by country leads. The key steps included team organisation, strategy formulation for survey dissemination and data collection, social media launch, and conducting a post-survey analysis amongst the collaborators. The core team convened weekly via video conference to discuss the modus operandi. The language barrier was managed through audio translation or by shifting to 'an interviewer-administered' questionnaire. Results: The core team included 11 members from seven countries, followed by 28 country leads from 110 countries. We also gathered 80 regional collaborators who provided feedback and spread the message. The Violence Study of Healthcare Workers and Systems (ViSHWaS) returned 5500 responses globally. Guiding principles garnered through this collaborative project include focusing on effective team organisation, ensuring external validation of survey tool, personalised communication, global networking, timely communication for maintaining momentum, and addressing regional limitations. The post-survey analysis showed that WhatsApp messaging was the most common modality used for survey dissemination, followed by in-person meetings and text messaging. We noted that the successful techniques were direct communication with respondents, regular progress updates, responsiveness to regional and country lead needs, and timely troubleshooting. The most common barriers for the respondents were limitations in language proficiency, technical fallouts, lack of compliance with, and difficulty understanding the questionnaire. Conclusions: In this global survey-based study of more than 5500 responses from over 110 countries, we noted valuable lessons in team management, survey dissemination, and addressing barriers to collaborative research.

RESUMEN

IMPORTANCE: The scientific community debates Generative Pre-trained Transformer (GPT)-3.5's article quality, authorship merit, originality, and ethical use in scientific writing. OBJECTIVES: Assess GPT-3.5's ability to craft the background section of critical care clinical research questions compared to medical researchers with H-indices of 22 and 13. DESIGN: Observational cross-sectional study. SETTING: Researchers from 20 countries from six continents evaluated the backgrounds. PARTICIPANTS: Researchers with a Scopus index greater than 1 were included. MAIN OUTCOMES AND MEASURES: In this study, we generated a background section of a critical care clinical research question on "acute kidney injury in sepsis" using three different methods: researcher with H-index greater than 20, researcher with H-index greater than 10, and GPT-3.5. The three background sections were presented in a blinded survey to researchers with an H-index range between 1 and 96. First, the researchers evaluated the main components of the background using a 5-point Likert scale. Second, they were asked to identify which background was written by humans only or with large language model-generated tools. RESULTS: A total of 80 researchers completed the survey. The median H-index was 3 (interquartile range, 1-7.25) and most (36%) researchers were from the Critical Care specialty. When compared with researchers with an H-index of 22 and 13, GPT-3.5 was marked high on the Likert scale ranking on main background components (median 4.5 vs. 3.82 vs. 3.6 vs. 4.5, respectively; p < 0.001). The sensitivity and specificity to detect researchers writing versus GPT-3.5 writing were poor, 22.4% and 57.6%, respectively. CONCLUSIONS AND RELEVANCE: GPT-3.5 could create background research content indistinguishable from the writing of a medical researcher. It was marked higher compared with medical researchers with an H-index of 22 and 13 in writing the background section of a critical care clinical research question.

RESUMEN

In this research paper, a novel process was developed for reactive printing of cotton fabric, with the objective of producing a high-quality printed fabric that is sustainable, eco-friendly, and low-cost which will ultimately reduce the impact of climate change. The study incorporated substituted tamarind polysaccharide (STP) obtained from agricultural waste, trichloro-ethanoic acid (TCEA), and polyethylene glycol (PEG-400) in the reactive printing paste. Tamarind starch was extracted from the seeds having 72 % yield, and substitution was performed to use it as a thickener in the printing paste. The conventional printing system was formulated with sodium alginate, urea, and sodium bicarbonate at dose levels of 2 %, 15 %, and 2.5 %, respectively, while the modified recipe was formulated with STP and TCEA at 5 % and 3 % dose levels, respectively along with varying doses of PEG-400 (0 %, 1 %, and 2 %) in novel prints. Various factors such as shade comparison, penetration, staining on the white ground, washing, rubbing, light and perspiration fastness, sharpness of edges, and fabric hardness were evaluated for all the recipes. The study demonstrated that the optimal outcomes were obtained with a 2 % PEG-400 dose level. This study represents a significant contribution to sustainable textile production, as tamarind agriculture waste was used as a raw material, which is an environmentally friendly alternative of sodium alginate that reduces the wastewater load. Additionally, PEG-400 was utilized as a nitrogen-free solubilizing moisture management substitution of urea for printing, while TCEA dissociated at high temperature to make alkaline pH during curing of the printed fabric to replace sodium bicarbonate. This research is a novel contribution to the printing industry, as these three constituents have not been previously used together other than this research group, in the history of reactive printing.

RESUMEN

OBJECTIVE: To provide insights into the nature, risk factors, impact and existing measures for reporting and preventing violence in the healthcare system. The under-reporting of violence against healthcare workers (HCWs) globally highlights the need for increased public awareness and education. METHODS: The Violence Study of Healthcare Workers and Systems study used a survey questionnaire created using Research Electronic Data Capture (REDCap) forms and distributed from 6 June to 9 August 2022. Logistic regression analysis evaluated violence predictors, including gender, age, years of experience, institution type, respondent profession and night shift frequency. A χ2 test was performed to determine the association between gender and different violence forms. RESULTS: A total of 5405 responses from 79 countries were analysed. India, the USA and Venezuela were the top three contributors. Female respondents comprised 53%. The majority (45%) fell within the 26-35 age group. Medical students (21%), consultants (20%), residents/fellows (15%) and nurses (10%) constituted highest responders. Nearly 55% HCWs reported firsthand violence experience, and 16% reported violence against their colleagues. Perpetrators were identified as patients or family members in over 50% of cases, while supervisor-incited violence accounted for 16%. Around 80% stated that violence incidence either remained constant or increased during the COVID-19 pandemic. Among HCWs who experienced violence, 55% felt less motivated or more dissatisfied with their jobs afterward, and 25% expressed willingness to quit. Univariate analysis revealed that HCWs aged 26-65 years, nurses, physicians, ancillary staff, those working in public settings, with >1 year of experience, and frequent night shift workers were at significantly higher risk of experiencing violence. These results remained significant in multivariate analysis, except for the 55-65 age group, which lost statistical significance. CONCLUSION: This global cross-sectional study highlights that a majority of HCWs have experienced violence, and the incidence either increased or remained the same during the COVID-19 pandemic. This has resulted in decreased job satisfaction.

RESUMEN

Lynch syndrome, an autosomal dominant genetic disorder, increases the risk of certain cancers, notably colorectal cancer. Early genetic testing and surveillance can significantly reduce associated morbidity and mortality. However, young patients face significant challenges navigating the healthcare system, with the psychological impact often neglected. Coping with the hereditary condition and elevated cancer risk can lead to distress, anxiety, and depression. Healthcare providers tend to focus on physical aspects, disregarding psychological well-being, leading to reduced treatment compliance and satisfaction. This case highlights the need for multidisciplinary teams and mental health support, emphasizing patient-centered care and support systems within the healthcare system.

RESUMEN

Fournier gangrene (FG) is a rare but rapidly progressing disease with a higher mortality rate in women as compared to men. This study aims to perform a literature review about FG in females and associated mortality and morbidity. We searched databases including MEDLINE (Ovid), the National Library of Medicine (Medical Subject Headings (MeSH)), the Cochrane Database of Systematic Reviews (Wiley), as well as Embase (Ovid), Scopus, and Global Index Medicus (WHO), and reviewed literature from 2002 to 2022 and selected 22 studies that met our study's inclusion criteria, which included 134 female patients with a mean age of 55±6 years. The perineal abscess was a more common nidus (n=41, 35%; 95%CI 23-39%) than vulvar pathology (n=29, 22%; 95%CI 15-30%). The most common initial presentation was cellulitis (n=62, 46%; 95%CI 38-55%), followed by perineal pain (n=54, 40%; 95%CI 32-50%), fever (n=47, 35%; 95%CI 27-43%), and septic shock (n=38, 28%; 95%CI 21-37%). Escherichia coli was the most frequently identified bacteria (n=48, 36%; 95%CI 28-46%). All patients had treatment with a mean of three (SD 2) debridement and those with negative pressure dressings received fewer debridements than those who received a conventional dressing. However, of those who had surgical intervention, 28 (20%; 95%CI 14-29%) patients underwent diversion colostomy. General surgeons performed 78% (n=104) of cases out of which 20% (n=20) were consulted by obstetrician-gynecologists, 14% (n=18) were treated by urologists, and only 8% (n=10) by plastic surgeons. The mean length of stay in the hospital was 24±11 days, and the gross mortality rate was 27 (20%; 95%CI 14-28%). In conclusion, while females have a low incidence rate of FG, they carry a higher mortality rate. Lack of cardinal signs and delayed presentation to the hospital from the onset of symptoms are some possible causes for the increased mortality rate along with the disease process being under-recognized in women. A high index of clinical suspicion is essential to avoid delay in the definitive management coupled with an early surgical consult and establishing a common general care pathway could minimize mortality and morbidity.

RESUMEN

The global demand for good quality food is going to be increased gradually. Mushrooms are broadly used as healthy nutritious meals. The nutritional values of extracts from four distinct Pleurotus species-Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus sapidus, and Pleurotus columbinus-were determined in the current study. Firstly, proximate analysis of selected Pleurotus species was performed followed by the Bradford assay to analyze the protein spectrophotometrically; high-performance liquid chromatography (HPLC) was performed for sugar determination while GC-MS was done to determine fatty acids on organic extracts of selected mushrooms. Descriptive statistics were used to calculate the percentages while significance was determined by SPSS statistics. The results depicted that fat, protein, ash, fiber, energy contents, and total carbohydrate were in the range of 0.64-2.02%, 16.07-25.15%, 2.1-9.14%, 6.21-54.12%, 342.20-394.30 kcal/100 g, and 65.66-82.47%, respectively. The protein's maximum concentration was observed in P. ostreatus followed by P. columbinus>P. sajor-caju>P. sapidus, sequentially. Various sugars may or may not be present in selected Pleurotus spps. Among the fatty acids, the prevalence of UFA was more than that of saturated fatty acids among all selected mushrooms. From this study, it is concluded that all four Pleurotus spps. have excellent nutritional composition and can be used as valuable food and a great source of biochemical compounds.

RESUMEN

Idiopathic hypertrophic cranial pachymeningitis (IHCP) is a rare chronic inflammatory disease characterized by diffuse thickening of the dura mater. Although IHCP mostly presents as a diffuse lesion, it may also occur as focal tumour-like lesions. Here we present the first reported case of IHCP associated with a Chiari type I malformation (CMI). A 65-year-old man presented with a one-year history of chronic headache and vertigo exacerbated by standing and neck flexion. The neurological examination was unremarkable except for tongue wasting and fasciculations. MRI demonstrated features of CMI and findings suggestive of IHCP. Posterior fossa decompression resulted in significant symptomatic improvement and the diagnosis of IHCP was confirmed on histopathology. Though there is no consensus about the management of IHCP in this case, we advocate surgical decompression with prolonged steroid therapy.

RESUMEN

Local transanal excision of early rectal carcinoma is an appealing treatment because of its low morbidity rates and better functional results than radical resection. However, this treatment approach is controversial due to its association with local recurrence when compared to the latter. This review aims to compare the local recurrence and mortality rates of local vs. radical excision in patients with T1N0M0 rectal carcinoma, based on data in the literature in the last 20 years. A PubMed, Cochrane, and Google Scholar search of published literature in the last 20 years was performed. A total of 12 studies were identified. Three were prospective, one was a population-based propensity matching study, one was a nationwide cohort study, one was a meta-analysis, and the remaining studies were retrospective/observational. The mean local recurrence rate within five years from the studies selected for local excision (LE: 12.8%) was nearly double that of radical excision (RAD: 5.0%). The five-year mean survival rate for both LE and RAD groups from the studies selected was 86%, which was equal for both groups. The main predictors of poor outcomes were older age and the presence of two or more comorbid conditions. There is a consensus amongst studies that LE is associated with inferior oncological outcomes such as postoperative complications and recurrence when compared to RAD. The higher local recurrence rates in LE are attributed to occult lymph node disease and inadequate adjunctive therapy due to suboptimal staging. There is no difference in the five-year survival rate when compared to RAD. A longer follow-up period is needed to determine whether the survival rates diverge after five years.

RESUMEN

BACKGROUND: Pancreatic cancer (PC) has the worst survival of all periampullary cancers. This may relate to histopathological differences between pancreatic cancers and other periampullary cancers. Our aim was to examine the distribution and histopathologic features of pancreatic, ampullary, biliary and duodenal cancers resected with a pancreaticoduodenectomy (PD) and to examine local trends of periampullary cancers resected with a PD. METHODS: A retrospective review of PD between January 2000 and December 2012 at a public metropolitan database was performed. The institutional ethics committee approved this study. RESULTS: There were 142 PDs during the study period, of which 70 cases were pre-2010 and 72 post-2010, corresponding to a recent increase in the number of cases. Of the 142 cases, 116 were for periampullary cancers. There were also proportionately more PD for PC (26/60, 43% pre-2010 vs 39/56, 70% post-2010, P = 0.005). There were 65/116 (56%) pancreatic, 29/116 (25%), ampullary, 17/116 (15%) biliary and 5/116 (4%) duodenal cancers. Nodal involvement occurred more frequently in PC (78%) compared to ampullary (59%), biliary (47%) and duodenal cancers (20%), P = 0.002. Perineural invasion was also more frequent in PC (74%) compared to ampullary (34%), biliary (59%) and duodenal cancers (20%), P = 0.002. Microvascular invasion was seen in 57% pancreatic, 38% ampullary, 41% biliary and 20% duodenal cancers, P = 0.222. Overall, clear margins (R0) were achieved in fewer PC 41/65 (63%) compared to ampullary 27/29 (93%; P = 0.003) and biliary cancers 16/17 (94%; P = 0.014). CONCLUSIONS: This study highlights that almost half of PD was performed for cancers other than PC, mainly ampullary and biliary cancers. The volume of PD has increased in recent years with an increased proportion being for PC. PC had higher rates of nodal and perineural invasion compared to ampullary, biliary and duodenal cancers.

RESUMEN

BACKGROUND: Patients with stroke symptoms but negative diffusion-weighted imaging (DWI) might have transient ischemic attacks (TIA) or stroke mimics. Brain DWI is important for the diagnosis of cerebral infarction but it is not available before thrombolysis for most patients to avoid treatment delay. This study aimed to evaluate the safety of IV thrombolysis in patients with a negative post-treatment DWI for cerebral infarction. METHODS: We conducted a retrospective study of 89 patients treated with IV recombinant tissue plasminogen activator (rt-PA) within 4.5 h after stroke symptom onset. The patients were identified in our acute stroke registry from January 2009 to September 2010. Information on patients' demographics, clinical characteristics, neuroimaging, treatment complications, and outcomes was obtained and analyzed. RESULTS: Out of 89 patients, 23 patients (26%) had a negative DWI on follow-up stroke imaging. Fourteen patients had a TIA and nine patients had a stroke mimic, including Todd's paralysis, complicated migraine, and somatoform disorder. We found significant differences between patients with a positive and a negative DWI in mean age (62 years vs. 52 years; P < 0.01) and median admission NIH stroke scale score (11 points versus 6 points; P < 0.001). Among patients with a positive DWI, four patients had a symptomatic intracerebral hemorrhage (ICH). No patients with a negative DWI had symptomatic or asymptomatic ICH. CONCLUSIONS: Our results suggest that the administration of IV rt-PA within the first 4.5 h of symptom onset in patients with suspected ischemic stroke is safe even when post-treatment DWI does not demonstrate cerebral infarction.
