RESUMEN

OBJECTIVES: Despite the critical value of healthcare workers (HCWs) demonstrated during the COVID-19 pandemic, there remains a noted global surge in violence against this population. The present meta-analysis aimed to gather data on the prevalence of workplace violence (WPV) against HCWs and to determine if there is any difference based on gender. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: A thorough search of PubMed/MEDLINE, Lilacs, and Cochrane Collaboration databases was conducted from the start of the COVID-19 pandemic until March 8, 2023. Two authors independently carried out screening, data extraction, and quality assessment, followed by statistical analysis using random-effects meta-analysis and subgroup analysis to assess heterogeneity. RESULTS: We included 22 studies with 44,357 participants, of which 79.37% were women. The analysis revealed an overall prevalence of WPV similar in both women (51.86%, 95% confidence interval [CI]: 41.39-62.33) and men (51.45%, 95% CI: 40.95-61.95). There were considerable differences in gender-based WPV across geographic regions. Aggressions tend to be higher toward men in Asia (odds ratio [OR] 0.79, 95% CI 0.74-0.85, P < 0.001). Conversely, in Latin America, WPV prevalence was higher in women (OR 1.20, 95% CI 1.01-1.4, P = 0.035). HCWs from low- middle-income-level countries suffered a higher incidence of violence irrespective of gender compared with high- and upper-middle-income countries (72.36% vs 47.35%). CONCLUSIONS: Our data indicate that more than half of HCWs experienced WPV during the COVID-19 pandemic. In addition, women and HCWs in low-middle-income countries were notably vulnerable to WPV. A deeper understanding of the nuances behind violence against HCWs will help to facilitate tailored strategies for different demographical contexts. REGISTRATION: PROSPERO ID: CRD42023403970.

RESUMEN

Atrial fibrillation (AF) is the most commonly sustained arrhythmia, and patients with diabetes mellitus (DM) exhibit an increased incidence of AF. Besides DM, heart failure (HF) shares pathophysiological links with AF, mainly related to the pathological remodeling of hearts affected by structural disease. As in a vicious circle, AF may contribute to HF worsening and increased mortality in patients with structural heart diseases, and the outcome may be further impaired when concomitant DM is present. Although no data directly referring to DM patients with HF are available, indirect information can be drawn from large studies on patients with HF and AF. The present review discusses the outcome of AF ablation in patients with DM and HF, focusing on safety, efficacy, and most particularly on hard endpoints such as mortality and thromboembolic event incidence.

RESUMEN

Chemokines are chemotactic cytokines that are mainly involved in the migratory patterns of immune cells. Few studies have evaluated the levels of chemokines in children with acute bacterial infections. The aim of this study was to evaluate the serum levels of chemokines MCP-1, RANTES, MIG and IP-10 in children with sepsis, community-acquired pneumonia (CAP) and skin abscess. Serum levels of MCP-1, RANTES, MIG and IP-10 were measured in 37 children with sepsis, 27 children with CAP, 25 children with skin abscess and 20 controls with no signs of infection. Patients with sepsis, CAP and skin abscess had higher concentrations of RANTES compared to controls (P = 0.0057, P = 0.0004 and P = 0.0108, respectively). IP-10 values were higher in patients with sepsis compared to children with skin abscess (P = 0.0075). However, MCP-1 levels were lower in septic patients compared to controls (P = 0.0136). There was no difference on MIG concentrations between the groups. Our original findings observed that RANTES was consistently elevated in all types of infections suggesting this chemokine may play an important role in the pathogenesis of bacterial infection. Additionally, patients with sepsis had a unique pattern of response with high levels of IP-10 but low levels of MCP-1, which should be further explored as the markers of disease severity.

RESUMEN

BACKGROUND: The approval of 9-δ-tetrahydocannabinol and cannabidiol (THC:CBD) oromucosal spray (Sativex) for the management of treatment-resistant multiple sclerosis (MS) spasticity opened a new opportunity for many patients. The aim of our study was to describe Sativex effectiveness and adverse events profile in a large population of Italian patients with MS in the daily practice setting. METHODS: We collected data of all patients starting Sativex between January 2014 and February 2015 from the mandatory Italian medicines agency (AIFA) e-registry. Spasticity assessment by the 0-10 numerical rating scale (NRS) scale is available at baseline, after 1 month of treatment (trial period), and at 3 and 6 months. RESULTS: A total of 1615 patients were recruited from 30 MS centres across Italy. After one treatment month (trial period), we found 70.5% of patients reaching a ≥20% improvement (initial response, IR) and 28.2% who had already reached a ≥30% improvement (clinically relevant response, CRR), with a mean NRS score reduction of 22.6% (from 7.5 to 5.8). After a multivariate analysis, we found an increased probability to reach IR at the first month among patients with primary and secondary progressive MS, (n=1169, OR 1.4 95% CI 1.04 to 1.9, p=0.025) and among patients with >8 NRS score at baseline (OR 1.8 95% CI 1.3-2.4 p<0.001). During the 6 months observation period, 631(39.5%) patients discontinued treatment. The main reasons for discontinuation were lack of effectiveness (n=375, 26.2%) and/or adverse events (n=268, 18.7%). CONCLUSIONS: Sativex can be a useful and safe option for patients with MS with moderate to severe spasticity resistant to common antispastic drugs.

RESUMEN

BACKGROUND AND PURPOSE: Natalizumab discontinuation induces the recurrence of multiple sclerosis disease activity: currently no therapeutic approach has been found able to abolish disease reactivation. METHODS: The recurrence of disease activity after natalizumab discontinuation was retrospectively evaluated in 79 patients who had been treated with immunomodulating agents, other first-line therapies, fingolimod or not treated. RESULTS: No differences have been found in clinical or magnetic resonance imaging recurrence of disease activity amongst the groups. Interestingly, no disease reactivation was observed only in one patient treated for 6 months with monthly pulses of cyclophosphamide. CONCLUSION: Disease modifying treatment or 'no treatment' is unable to abolish disease activity reactivation after natalizumab discontinuation.

RESUMEN

A total of 1357 specimens of Alaska skate Bathyraja parmifera were collected in the eastern Bering Sea by fisheries observers and during scientific groundfish surveys from 2003 to 2005. Male and female gonads were examined for maturity stage and seasonal reproductive timing. Based on seasonal reproductive data, including the occurrence of egg cases, ovum size, ovum number, shell-gland width and gonado-somatic index, this species appears to reproduce continually throughout the year. Potential effects of maternal size upon the size and number of mature oocytes were also investigated, with total length having a significant, although weak, influence on both. Morphology of a single intersexual individual encountered during the collection period is also described.

RESUMEN

Bevacizumab has demonstrated activity in patients with recurrent glioblastoma. However, the impact of prognostic factors associated with recurrent glioblastoma treated with cytotoxic agents has not been determined in patients treated with bevacizumab. To analyze the prognostic factors and clinical benefits of bevacizumab and irinotecan treatment in patients with recurrent glioblastoma. This monocentric study retrospectively analyzed all patients with recurrent glioblastoma who were treated with at least one cycle of bevacizumab and irinotecan at our institution from April 2007 to May 2010. Multivariate analysis was used to analyze prognostic factors for overall survival (OS) from the initiation of bevacizumab administration. Among the 100 patients that were identified (M/F: 65/35), the median age was 57.9 years (range: 18-76). Karnofsky Performance Status (KPS) was <70 in 44 patients and ≥ 70 in 56 patients; 83 % of the patients were on steroids. The median tumor area was 2012 mm². The median progression free survival was 3.9 months (CI 95 %: 3.4-4.3). The median OS was 6.5 months (CI 95 %: 5.6-7.4). Multivariate analysis revealed that OS was affected by KPS (p = 0.024), but not by gender, age, steroid treatment, number of previous lines of treatment, tumor size, or time from initial diagnosis. KPS was improved in 30 patients, including 14/44 patients with an initial KPS <70. The median duration of maintained functional independence (KPS ≥ 70) was 3.75 months (CI 95 %: 2.9-4.6). The median OS from initial diagnosis was 18.9 months (CI 95 %: 17.5-20.3). In patients with recurrent glioblastoma treated with bevacizumab, KPS was revealed as the only factor to impact OS. The clinical benefits associated with this regimen appear valuable. A positive impact of bevacizumab administration on OS of patients with glioblastoma multiforme is suggested.

RESUMEN

Prior to 2009 dengue fever had not been reported in the Andaman and Nicobar archipelago. In 2009, a few patients with dengue fever-like illness were reported, some of whom tested positive for dengue antibodies. In 2010, 516 suspected cases were reported, including some with dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS); 80 (15·5%) were positive for dengue antibodies. DENV RNA was detected in five patients and PCR-based typing showed that three of these belonged to serotype 1 and two to serotype 2. This was confirmed by sequence typing. Two clones of dengue virus, one belonging to serotype 1 and the other to serotype 2 appeared to be circulating in Andaman. Emergence of severe diseases such as DHF and DSS might be due to recent introduction of a more virulent strain or because of the enhancing effect of sub-neutralizing levels of antibodies developed due to prior infections. There is a need to revise the vector-borne disease surveillance system in the islands.

RESUMEN

BACKGROUND AND OBJECTIVES: We describe the development of Preanestes@s, a web-based application for preoperative assessment, which incorporates PreQuest, a smart computer-based self-assessment questionnaire for the automated management of information. Preanestes@s potentially enables remote non-telephonic preoperative assessment. The main objective of this work was the identification of factors that independently predict adequate completion of PreQuest. As a secondary objective, we assessed patient experience using the application. MATERIAL AND METHODS: To assess the influence of patient conditions on PreQuest completion, our sample included 880 adult patients scheduled to undergo surgery at our institution between February 2020 and February 2021. We evaluated patient satisfaction and acceptability with the use of the application and PreQuest. RESULTS: A total of 573 participants (65.1%) successfully completed the PreQuest. Age below 65 years and higher educational attainment were identified as independent predictors for PreQuest completion (p = 0.04 and p = 0.001, respectively). Most (89.4%) participants agreed that Preanestes@s was intuitive and easy to use, with over 85% showing high levels of acceptance of PreQuest prototype's communication improvement and ease of use. The final version of Preanestes@s and PreQuest was evaluated by 218 participants, many of whom (>74%) affirmed its ease of use. CONCLUSIONS: The use of Preanestes@s for preoperative assessment is supported by high levels of satisfaction with the prototype and by an eQuest completion rate greater than 65% in a non-selective population. In our sample, younger age and higher education attainment predicted higher rates PreQuest completion. Trial registration number NCT04259268.

RESUMEN

AIMS: Recent data identified uric acid as an independent risk factor for cardiovascular disease. The aim of the present study was to assess the association between uric acid and endothelial dysfunction in 57 patients with Type 1 diabetes and 53 healthy control subjects. METHODS: Microvascular endothelial function was evaluated using laser Doppler perfusion monitoring coupled with pharmacological (iontophoretic administration of acetylcholine and sodium nitroprusside) and physiological (post-occlusive reactive hyperaemia and thermal hyperaemia) stimuli. RESULTS: Uric acid was higher in subjects without diabetes than in those with diabetes (P = 0.03). Microvascular vasodilator response to acetylcholine was significantly reduced in Type 1 diabetes (P = 0.002) and was correlated to disease duration (r = -0.3, P = 0.01), triglyceride (r = -0.37, P = 0.005), insulin dose (r = -0.28, P = 0.03), fasting plasma glucose levels (r = -0.3, P = 0.02), HbA(1c) (r = -0.34, P = 0.001) and uric acid (r = -0.3, P = 0.005). On stepwise multivariate analysis, age, HbA(1c) and uric acid were the most important independent variables that were associated with the endothelium-dependent response in Type 1 diabetes (P = 0.02). CONCLUSIONS: Glycaemic control and uric acid in the normal range were the most important contributing factors to the decreasing endothelium-dependent responses associated with Type 1 diabetes. Consequently, uric acid could be a new potential marker of microvascular endothelial dysfunction in these patients. Further studies are required to explore the clinical relevance of the relationship between uric acid levels, oxidative stress and endothelial dysfunction in patients with Type 1 diabetes, as well as whether treatment with uric acid-lowering drugs for slight elevations in uric acid would benefit these patients.

RESUMEN

The purpose of this study was to assess the effect of antenatal weight gain on baseline heart rate variability and incidence of hypotension in singleton parturients with a normal pre-pregnancy body mass index, presenting at term for elective caesarean section under spinal anaesthesia. Sixty-six parturients, of ASA physical status 1-2, were allocated to one of three groups according to their weight gain during pregnancy: < 11 kg; 11-16 kg; and > 16 kg. Mean (SD) approximate entropy of baseline heart rate was significantly higher in the < 11 kg group (0.27 (0.11)) compared with the 11-16 kg group (0.14 (0.08)) and the > 16 kg group (0.14 (0.07)) (both p < 0.001). The incidence of hypotension in the < 11 kg group (17/22; 77%) was significantly higher than in the 11-16 kg group (7/22; 32%) (p = 0.006) and the > 16 kg group (8/22; 36%) (p = 0.01). We conclude that weight gain < 11 kg during pregnancy is associated with increased baseline heart rate variability and a higher incidence of hypotension at the time of elective caesarean section under spinal anaesthesia.

RESUMEN

INTRODUCTION: Due to its high transmissibility, measures aimed at reducing the spread of SARS CoV2 have become mandatory. Different organizations have recommended performing polymerase chain reaction tests (PCR) as part of the preoperative screening of surgical patients. We aimed to determine the performance of PCR testing to detect asymptomatic carriers. METHODS: Observational study carried out at a tertiary care center. We compared the results of preoperative real-time reverse-transcription-PCR test (RT-PCR) performed on a cohort of patients pending surgery with the results we would have expected assuming the epidemiological data released by government offices. RESULTS: We registered no positives in the 2,722 preoperative RT-PCR tests performed in our health care area between epidemiological Weeks 18 to 21, meaning a cumulative incidence trending to zero. Assuming public epidemiological data, the probabilistic projection of potential asymptomatic individuals ranged from 0.27 × 10e-4 (according to official data of new cases diagnosed by PCR) to 4.69 × 10e-4 if we assumed cases confirmed by IgG test in our province. Assuming a RT-PCR sensitivity of 95%, to obtain a positive result we should perform 38,461 and 2,028 tests respectively. CONCLUSIONS: In scenarios of very low prevalence and despite high sensitivity scores, indiscriminate preoperative RT-PCR screening is of a questionable effectiveness for detecting asymptomatic carriers. Our findings evidence the difficulty of establishing reliable predictive models for the episodic and rapidly evolving incidence of infections such as has characterized the SARS CoV2 pandemic.

RESUMEN

Reduced sarcoplasmic calcium ATPase (SERCA2a) expression has been shown to play a significant role in the cardiac dysfunction in diabetic cardiomyopathy. The mechanism of SERCA2a repression is, however, not known. This study was designed to examine the effect of resveratrol (RSV), a potent activator of SIRT1, on cardiac function and SERCA2a expression in chronic type 1 diabetes. Adult male mice were injected with streptozotocin (STZ) and fed with either a regular diet or a diet enriched with RSV. STZ administration produced progressive decline in cardiac function, associated with markedly reduced SERCA2a and SIRT1 protein levels and increased collagen deposition; RSV treatment to these mice had a tremendous beneficial effect both in terms of improving SERCA2a expression and on cardiac function. In cultured cardiomyocytes, RSV restored SERCA2 promoter activity, which was otherwise highly repressed in high-glucose media. Protective effects of RSV were found to be dependent on its ability to activate Silent information regulator (SIRT) 1. In cardiomyocytes, overexpression of SIRT1 was found sufficient to activate SERCA2 promoter in a dose-dependent manner. In contrast, pretreatment of cardiomyocytes with SIRT1 antagonist, splitomycin, blocked these beneficial effects of RSV. In addition, SIRT1 knockout (+/-) mice were also found to be more sensitive to STZ-induced decline in SERCA2a mRNA. The data demonstrate that, in chronic diabetes, 1) the enzymatic activity of cardiac SIRT1 is reduced, which contributes to reduced expression of SERCA2a and 2) through activation of SIRT1, RSV enhances expression of SERCA2a and improves cardiac function.

RESUMEN

Sternal fractures are considered uncommon in pediatric patients. Classically, they have been described as fractures secondary to high-energy trauma that have a risk of associated lesions. OBJECTIVE: To describe the clinical and imaging features of sternal fractures in patients less than 18 years of age. MATERIAL AND METHODS: We retrospectively reviewed 79 pediatric patients diagnosed with sternal fractures after trauma. RESULTS: We found that 92.4% of the fractures were caused by low-energy trauma and that associated lesions were present in only 3 (4%) patients. CONCLUSION: Our results suggest that sternal fractures in children are often due to lesser trauma and that associated lesions are rare.

RESUMEN

AIM: The prevalence of cardiovascular autonomic neuropathy (CAN) in diabetes mellitus is well documented. However, the rate and predictors of both the development and progression of CAN have been less studied. Hereby, we assessed the rate and the major risk factors for CAN initiation and progression in a cohort of type 1 diabetic patients followed over a three-year period. METHODS: 175 type 1 diabetic patients (mean age: 50 ± 11 years; female/male: 76/99) with positive bedside screening for CAN were included and underwent 2 standardized autonomic testings using 4 standardized tests (deep breathing, Valsalva maneuver, 30/15 ratio, and changes in blood pressure during standing), separated by 3 ± 1 years. CAN staging was achieved according to the Toronto Consensus Panel on Diabetic Autonomic Neuropathy into 4 categories: absent, possible, confirmed, or severe CAN. RESULTS: Out of the 175 patients included, 31.4% were free of CAN, 34.2% had possible CAN, 24.6% had confirmed CAN, and 9.7% exhibited severe CAN at the first assessment. Among the 103 patients with nonsevere CAN at inclusion, forty-one (39.8%) had an increase of at least one category when reassessed and 62 (60.2%) remained stable. A bivariate analysis indicated that only BMI and exposure to selective serotonin reuptake inhibitors (SSRIs) were significantly different in both groups. A multivariate analysis indicated that lower BMI (OR: 0.15, CI 95%: 0.05-0.48, p = 0.003) and SSRI exposure (OR: 4.18, CI 95%: 1.03-16.97, p = 0.04) were the sole predictors of CAN deterioration. In the 55 patients negative for CAN at the first laboratory assessment, 12 became positive at the second assessment. CONCLUSION: No clear predictive factor for CAN onset was identified. However, once present, CAN progression was related to low BMI and SSRI exposure.

RESUMEN

Many deceased by neurologic criteria donors are administered inhalational agents during organ recovery surgery-a process that is characterised by warm and cold ischaemia followed by warm reperfusion. In certain settings, volatile anaesthetics (VA) are known to precondition organs to protect them from subsequent ischaemia-reperfusion injury. As such, we hypothesised that exposure to VA during organ procurement would improve post-graft survival. Lifebanc (organ procurement organisation [OPO] for NE Ohio) provided the investigators with a list of death by neurologic criteria organ donors cared for at three large tertiary hospitals in Cleveland between 2006 and 2016-details about the surgical recovery phase were extracted from the organ donors' medical records. De-identified data on graft survival were obtained from the United Network for Organ Sharing (UNOS). The collated data underwent comparative analysis based on whether or not VA were administered during procurement surgery. Records from 213 donors were obtained for analysis with 138 exposed and 75 not exposed. Demographics, medical histories, and organ procurement rates were similar between the two cohorts. For the primary endpoint, there were no significant differences observed in either early (30-day) or late (five-year) graft survival rates for kidney, liver, lung, or heart transplants. Our findings from this retrospective review of a relatively small cohort do not support the hypothesis that the use of VA during the surgical procurement phase improves graft survival. Reviews of larger datasets and/or a prospective study may be required to provide a definitive answer.

RESUMEN

BACKGROUND: Dimethyl-fumarate (DMF) demonstrated efficacy and safety in relapsing-remitting multiple sclerosis (MS) in randomized clinical trials. OBJECTIVES: To track and evaluate post-market DMF profile in real-world setting. MATERIALS AND METHODS: Patients receiving DMF referred to Italian MS centres were enrolled and prospectively followed, collecting demographic clinical and radiological data. RESULTS: Among the 735 included patients, 45.4% were naïve to disease-modifying therapies, 17.8% switched to DMF because of tolerance, 27.4% switched to DMF because of lack of efficacy, and 9.4% switched to DMF because of safety concerns. Median DMF exposure was 17 months (0-33). DMF reduced the annual relapse rate (ARR) by 63.2%. At 12 and 24 months, 85 and 76% of patients were relapse-free. NEDA-3 status after 12 months of DMF treatment was maintained by 47.5% of patients. 89 and 70% of patients at 12 and 24 months regularly continued DMF. Most frequent adverse events (AEs) were flushing (37.2%) and gastro-enteric AEs (31.1%). CONCLUSION: Our post-market study corroborated that DMF is a safe and effective drug. Additionally, the study suggested that naïve patients strongly benefit from DMF and that DMF improved ARR also in patients who were horizontally switched from injectable therapies due to tolerability and efficacy issues.
