Prevalence and influencing factors of social alienation among elderly patients undergoing radical prostatectomy for prostate cancer

Abstract Objectives This study aims to not only investigate the prevalence of social alienation among elderly patients undergoing radical prostatectomy for prostate cancer but also identify the contributing factors. Materials and methods A total of 245 elderly patients diagnosed with prostate cancer and undergoing radical prostatectomy at a tertiary care general hospital in Jinan were included in this study. To assess the patients, several questionnaires were used. These included the General Situation Questionnaire, General Alienation Scale, Social Impact Scale, Modified Memorial Anxiety Scale for Prostate Cancer, and Perceived Social Support Scale. Pearson correlation analysis was conducted to examine the relationships between variables, whereas multiple linear regression was used to identify the factors influencing social alienation among patients who underwent radical prostatectomy. Results Patients who underwent radical prostatectomy had a mean total score of 44.13 ± 7.24 on the Social Alienation Scale. The results of the Pearson correlation analysis indicated that social alienation showed an inverse association with social support (r = −0.627, p < 0.05) and positive associations with age, disease stigma, and anxiety (r = 0.325, 0.575, 0.421, all p’s < 0.01) among patients who underwent radical prostatectomy. The findings from multiple linear regression analysis demonstrated that educational level, age, urinary incontinence, disease stigma, anxiety, and social support significantly influenced social alienation among elderly patients who underwent radical prostatectomy (p < 0.05). Conclusions Elderly patients who undergo radical prostatectomy often experience social alienation. This study found that social alienation was associated with factors such as educational level, age, urinary incontinence, social support, anxiety, and disease stigma. Consequently, healthcare providers should actively monitor the degree of social alienation in elderly patients after radical prostatectomy and provide suitable psychological care to facilitate positive social reintegration and alleviate their feelings of social alienation.

Carbapenemase Genes, Virulence Genes, and Molecular Epidemiology of Carbapenem-Resistant Klebsiella pneumoniae Derived From Bloodstream Infections

To investigate the clinical characteristics and molecular epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) isolated from patients with bloodstream infections in a large tertiary-care general hospital in Southwest China. A total of 131 strains of non-repeating CRKP were collected from the blood cultures of patients who had bloodstream infections in 2015-2019. The strains were identified by VITEK-2, a fully automated microbial analyzer, and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. The minimum inhibitory concentration (MIC) was determined by microbroth dilution method. The common carbapenemase resistant genes and virulence factors were identified by PCR. Homology analysis was performed by multilocus sequencing typing. Whole genome sequencing was performed to analyze the genomic characteristics of CRKP without carbapenemase. The 131 strains of CRKP showed resistance to common antibiotics, except for polymyxin B (1.6% resistance rate) and tigacycline (8.0% resistance rate). A total of 105 (80.2%) CRKP strains carried the Klebsiella pneumoniae carbapenemase (KPC) resistance gene, 15 (11.4%) strains carried the New Delhi Metallo-β-lactamase (NDM) gene, and 4 (3.1%) isolates carried both KPC and NDM genes. Sequence typing (ST) 11 (74.0%) was the dominant sequence type. High detection rates for mrkD (96.2%), fimH (98.5%), entB (100%), and other virulence genes were reported. One hypervirulent CRKP strain was detected. The seven strains of CRKP that did not produce carbapenemase were shown to carry ESBL or AmpC genes and had anomalies in membrane porins OMPK35 and OMPK36, according to whole genome sequencing. In a large-scale tertiary-care general hospital, CRKP mainly carries the KPC gene, has a high drug resistance rate to a variety of antibiotics, and possesses multiple virulence genes. Attention should be paid to CRKP strains with high virulence.

Psychological Well-Being of Nurses with One to Five Years of Clinical Experience.

Nurses are required to fulfill many roles, including expertise, communication, and leadership and are psychologically vulnerable due to lack of manpower, emotional labor, and shift work. Among them, it is necessary to understand the psychological well-being of new nurses and junior nurses who have a high early resignation rate. The purpose of this study was to investigate psychological well-being of nurses and compare psychological well-being of nurses from the first to the fifth years of clinical experience. Cross-sectional comparative design and purposive sampling method were used. Data were collected from 148 nurses with one to five years of experience working in tertiary care general hospitals. On November 11, 2021, an online link for the structured questionnaire was sent to the group social networking service accounts for nurses. Psychological well-being was assessed using a Korean version of the Scales of Psychological Well-being including autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance. The average psychological well-being of nurses was 194.11, with significant differences depending on years of clinical experience (p = .006, F = 3.82) and satisfaction with nursing (p < .001, F = 13.12). It was lowest at 180.08 in the first year, gradually improving, but falling again from the fourth year. Among five subfactors except positive relations with others (p = .389), psychological well-being was related to clinical experiences years using satisfaction with nursing and religion as covariates. This study that compared psychological well-being from the first to the fifth year according to clinical experience revealed the need for optimized intervention for each year. Nursing managers can improve the psychological well-being of nurses through active and appropriate intervention according to the passage of nursing experience.

Evaluation of the use of antibiotics using the anatomical therapeutic chemical/defined daily dose and Gyssens methods in pneumonia patients at a tertiary care general hospital in Medan

Background: The impact of irrational antibiotic usage in pneumonia patients is an increase in resistance, an increase in drug side effects, and a failure of therapy that causes patients' health to deteriorate, lowering their quality of life and raising their treatment costs. The primary objective of this study is to assess the extent to which antibiotics are being used rationally in the inpatient facility of a private tertiary care hospital located in Medan. Methods: The present study employs an observational design with a prospective cross-sectional approach, carried out within the timeframe of September to November 2022. The evaluation of antibiotic utilization was conducted utilizing the anatomical therapeutic chemical (ATC)/defined daily dose (DDD) methodology and the Gyssens methodology. Results: The findings of the study indicate that a significant proportion of individuals diagnosed with pneumonia fell between the age range of 46 to 55 years, comprising 23.4% of the overall patient population. Moreover, the male gender was found to be the most prevalent, accounting for 55.81% of the 278 patients who satisfied the inclusion criteria. The findings from the evaluation of antibiotic utilization, employing the ATC classification system and DDD methodology, yielded a rate of 145.72 DDD per 100 days of care. Ceftriaxone exhibited the highest value, reaching 87.59 DDD/100 days of treatment. The evaluation of the Gyssens approach yielded a total of 254 patients who were administered antibiotics in an appropriate manner (category 0), while 24 patients were found to have received unsuitable antibiotics (categories I-VI). Conclusions: Based on the findings of this study, it can be inferred that the utilization of antibiotics within the hospital under investigation remains inadequate in terms of both quantity and quality.

Tele-Mentored Handheld Ultrasound System for General Practitioners: A Prospective, Descriptive Study in Remote and Rural Communities.

Rural general practitioners (GPs) have insufficient diagnostic information to deal with complex clinical scenarios due to the inequality in medical imaging resources in rural and remote communities. The objective of this study is to explore the value of a tele-mentored handheld ultrasound (tele-HHUS) system, allowing GPs to provide ultrasound (US) services in rural and remote communities. Overall, 708 patients underwent tele-HHUS examination between March and October 2021 and March and April 2022 across thirteen primary hospitals and two tertiary-care general hospitals. All US examinations were guided and supervised remotely in real time by US experts more than 300 km away using the tele-HHUS system. The following details were recorded: location of tele-HHUS scanning, primary complaints, clinical diagnosis, and US findings. The recommendations (referral or follow-up) based on clinical experience alone were compared with those based on clinical experience with tele-HHUS information. Tele-HHUS examinations were performed both in hospital settings (90.6%, 642/708) and out of hospital settings (9.4%, 66/708). Leaving aside routine physical examinations, flank pain (14.2%, 91/642) was the most common complaint in inpatients, while chest distress (12.1%, 8/66) and flank discomfort (12.1%, 8/66) were the most common complaints in out-of-hospital settings. Additionally, the referral rate increased from 5.9% to 8.3% (kappa = 0.202; p = 0.000). The tele-HHUS system can help rural GPs perform HHUS successfully in remote and rural communities. This novel mobile telemedicine model is valuable in resource-limited areas.

Current Status of and Barriers to the Implementation of Enhanced Recovery After Surgery in 77 Tertiary Hospitals

To investigate the status of and obstacles to the implementation of enhanced recovery after surgery (ERAS) in tertiary-care general hospitals in China. Questionnaire on the Current Status of and Barriers to the Implementation of ERAS in Tertiary-Care Hospitals, a self-developed questionnaire, was used to conduct a survey of 77 tertiary hospitals from 21 provinces across China between May 2022 and June 2022. The participating hospitals were selected by convenience sampling. The questionnaire on the current implementation status of ERAS was mainly focused on the departments involved and the ERAS programs implemented, incorporating a total of 25 items of three dimensions, preoperative, intraoperative, and postoperative. The answer to each question consisted of 5 options from "never" to "always", which corresponded to 1 to 5 points on the scoring scale, with the higher scores indicating better implementation of the program concerned. In the questionnaire on barriers to ERAS implementation and recommendations, 10 items of two dimensions, including hospital management, and patient and caregiver, were concerned with the barriers to implementation. The answer to each question consisted of 5 options from "disagree" to "strongly agree", which corresponded to 1 to 5 points on the scoring scale, with the higher scores indicating the greater importance of the barriers. ERAS programs were implemented in 73 (94.8%) hospitals. The best-implemented items were preoperative education (4.73±0.51), prevention and treatment of deep vein thrombosis (4.55±0.71), and postoperative follow-up (4.40±0.81). The items of poor implementation status were preoperative prehabilitation (2.71±1.40), preoperative oral carbohydrate drinks (3.03±1.49), and early ambulation after surgeries (3.04±1.22). The main obstacles to ERAS implementation included a lack of effective incentive systems, poor motivation among the medical and nursing staffs (3.21±0.93), a lack of disease-specific clinical implementation pathways (3.16±1.06), and a lack of experience in multidisciplinary teamwork (2.98±1.17). There is a high rate of ERAS implementation in tertiary general hospitals in China, but clinical implementation and dissemination are still confronted with many obstacles.

Socio-demographic correlates and psychosocial stressors among suicide attempters attending a tertiary care general hospital

Abstract Introduction: Suicide is a rapidly growing and critical public health concern in India and around the world. Interpersonal, social, familial, psychological along with genetic vulnerabilities were important risk factors for suicidal attempts. Methods: This was a hospital-based cross-sectional study done at King George Hospital, Visakhapatnam. All the suicide attempters admitted to the General Medicine department were evaluated at the psychiatric department. A total of 117 patients were included in our study with convenient sampling. Beck’s suicide intent scale, Presumptive stressful life event scale, and semi-structured proforma for socio-demographic and clinical variables were used to assess the study participants. Results: Financial struggles (19.6%) and conflict with family members (14.5%) were the stressful life events among most of the suicide attempts. Most of the study sample used pesticide consumption (20.5%) as the commonest mode of suicidal attempt. The majority of the suicide attempters (53%) had medium suicidal intent. There was a significant association between marriage and stressful life event score (p=0.001). The use of pesticides was significantly higher among men than women (p=0.002) and the use of household agents was significantly high among women than men (p=0.013). Conclusion: Psychosocial stressors also play an important role in attempting suicide and hence to prevent suicidal attempts, there is a need for the development of innovative strategies to decrease the stigma, to improve coping skills and to promote help-seeking from mental health services.

Benzodiazepine-Receptor Agonist Utilization in Outpatients with Anxiety Disorder: A Retrospective Study Based on Electronic Healthcare Data from a Large General Tertiary Hospital.

Benzodiazepine-receptor agonists (BZRAs), including benzodiazepines (BZDs) and drugs related to BZDs (Z-drugs), are commonly used for anxiety, but often have side effects. We retrospectively investigated the utilization and prescription characteristics of BZRAs for patients with anxiety disorders in a large tertiary care general hospital between 2018 and 2021, based on electronic healthcare records. We also examined the pattern of simultaneous consumption of multiple BZRA drugs, and the diseases coexisting with anxiety that are associated with this. The numbers of patients and BZRA prescriptions increased over the 4 years. Moreover, 7195 prescriptions from 694 patients contained two or more BZRAs, of which 78.08% contained both BZDs and Z-drugs, 19.78% contained multiple BZDs, and 2.14% contained multiple Z-drugs. For anxiety patients with concomitant Alzheimer's disease or Parkinson's disease, and dyslipidemia, they were more likely to consume multiple BZRAs simultaneously, whereas patients with concomitant insomnia, depression, hypertension, diabetes, or tumors were less likely to consume multiple BZRAs (all p < 0.05). Furthermore, older patients who consume multiple BZRAs simultaneously may have higher probabilities of long-term drug use. Better interventions supporting standardized BZD utilization may be needed to minimize the side effects of inappropriate BZRA administration.

Determinants of Treatment Outcome, Follow-Up, and Abstinence Rates Among Patients With Alcohol Use Disorder: A Prospective Study.

Background The treatment of alcohol use problems needs to have a multidimensional approach for early recovery and better outcome. Objective The study aimed to study the socio-demographic, clinical, and psychological factors associated with the three-month clinical outcomes among patients with alcohol use disorder treated in a tertiary care general hospital psychiatric unit in southern India. Methods This is a prospective three-month follow-up study. Patients fulfilling the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria for alcohol use disorder were selected for the study. The baseline severity of alcohol use was assessed by the Severity of Alcohol Dependence Questionnaire, alcohol craving by Alcohol Craving Questionnaire (ACQ), impulsivity by Barratt Impulsiveness Scale, anxiety and depression by Hospital Anxiety and Depression Scale and personality traits by Personality inventory for DSM-5. Craving was assessed at 2, 4, 8 and 12 weeks post-discharge. Results A total of 110 patients participated in the study. After 3 months of follow-up, 75.5% of the patients remained abstinent throughout the follow-up period. The sample was divided into two groups based on the abstinent status at 12 weeks. Both the abstinent and relapsed users were compared based on socio-demographic, marital, family, illness-related, alcohol-usage, and psychological characteristics, the baseline and follow-up craving indices. There were no statistically significant differences between the two groups based on socio-demographic characteristics. Compared to the relapsed group, the abstinent individuals displayed increased adherence to follow-up visits and attended more frequent individual therapy sessions, however, there were no significant differences between the two groups in the number of group therapy sessions attended.Also, the abstinent group demonstrated lower subjective craving at both the baselineand during follow-up. The relapsed users had reported a significantly greater proportion of history of suicide in the family. Further correlational analyses were done to find the direction of associations between psychological characteristics and alcohol-usage characteristics. High attentional impulsivityand motor impulsivitywere associated with early age of first use. High attentional impulsivity, motor impulsivityand impulsive planningwere associated with early age of dependence. Early age of dependence was associated with increased levels of antagonism and psychoticism. Younger onset of alcohol use was associated with increased levels of craving at baseline. The baseline alcohol use severity and the baseline craving towards alcohol were positively correlated with follow-up craving indices as per ACQ and craving index (CI) scales. Conclusion The patients who were abstinent displayed reduced subjective craving towards alcohol at baseline and were more adherent in attending individual and group therapy sessions. Among the relapsed users, most relapsed before four weeks and had a family history of alcohol dependence, family history of psychosis, and suicide, which is indicative of high genetic loading of substance abuse leading to early initiation and early onset of alcohol dependence. The effects of genetic loading could be possibly mediated by traits of high impulsivity, psychoticism, and antagonism.

Disability in Patients With Bipolar Disorder in Full or Partial Remission: A Cross-Sectional Study.

Objective: To evaluate the level of disability and identify an association between sociodemographic and clinical variables and disability in patients with bipolar disorder (BD). Methods: This cross-sectional study was conducted in a tertiary care general hospital psychiatric unit with 100 patients with BD in partial or full remission (DSM-IV-TR criteria) from January 2017 to March 2018. Patients were assessed using a semistructured proforma, the Mini-International Neuropsychiatric Interview 5.0–Hindi version, the Hamilton Depression Rating Scale (HDRS) or the Young Mania Rating Scale (YMRS), and the Indian Disability Evaluation and Assessment Scale (IDEAS). Results: All patients with BD had at least mild disability. The mean ± SD IDEAS global score was 5.1 ± 2.59. Of the sample, 66% and 34% had mild or moderate, disability, respectively. The global score of disability was associated with the number of episodes, number of manic episodes, frequency of episodes in the past year, YMRS and HDRS scores, partial remission, and hospitalization. Categories of disability were associated with the type of last episode, type of remission, and treatment setting. Conclusions: Patients with BD had at least a mild level of disability even during remission. Disability worsened with the increasing number, frequency, and severity of episodes; number of manic episodes; partial remission; and hospitalization.

Public-Private Partnership (PPP) Model of Psychiatry Day Care Center in India: Its Challenges and Opportunities-A 2-Year Experience.

Background Most patients admitted in day care center are suffering from schizophrenia who do not recover fully due to nagging negative symptoms and cognitive deficits which linger and persist making the patients unfit and unacceptable for employment. But regular employment can help in recovery. In this way, day care centers would help in recovery of patients and hence the need for these kinds of centers. In India, day care centers are in infancy stage and to a larger extent are inadequately used. There is no data available from psychiatry day care center run as public–private partnership (PPP) project in a tertiary care general hospital psychiatry unit (GHPU). This model is first of its kind in India. Here, we narrate experiences gained in last 2 years. Objectives This article narrates the challenges and opportunities in a psychiatry day care center in PPP model. Materials and Methodology It a cross-sectional study. Description of day care center: Day care center was started as PPP model called Manasadhara model in the state of Karnataka, first of its kind in India.Recruitment Patients currently asymptomatic are recruited into the center after initial interview/assessment of patients and family members from the in-charge psychiatrist after obtaining informed consent. Statistical Analysis Data are analyzed using mean and median mode. A p -value of < 0.05 was considered significant. Appropriate statistical methods were applied. Results Total number of patients recruited in the study were 33 ( n = 33). Mean age of the patients was 34.5 (7.4) years. Majority (51.52%) of patients were in the age group of between 26 and 35 years. Majority (51.52%) of patients' age of onset of illness fell between 21 and 30 years, and 63.64% of patients' duration of illness ranged between 11 and 15 years.Conclusion Running a day care center in PPP model that too in a GHPU set up is difficult. Skills in which patients need to be trained should be decided based on patients' profile and cultural basis of the place. Common problems faced were poor placements, transportation, financial difficulties, and poor funding.

Profiles of the Patients and Their Referral Patterns Visiting the Psychiatry Clinic of a General Hospital Setting Located in a Mental Health Resource Deficient Region of India: A Retrospective Observational Study.

Objectives Treatment for mental health problems is determined by cultural, health infrastructure, and illness-related factors. Literature is sparse from India, particularly from the mental health resources-deficient regions of the country such as central India. Therefore, the current study is aimed at assessing the profile of the patients visiting the psychiatry outpatient facility (OPF) of a tertiary-care general hospital setting (GHS), their referral patterns, and their determinants. Materials and Methods A retrospective chart review of the newly registered individuals (October 2019 to March 2020) in the psychiatry OPF of the GHS from Central India was used in the study. Data (sociodemographic profiles, illness characteristics, and referral patterns) were extracted as per the standard guidelines. Statistical Analysis Descriptive statistics were used to represent sociodemographic, illness-, and past treatment-related characteristics of the participants. Chi-squared test was used to compare the referral characteristics of the two groups (self-referred patients vs. those referred by others, dependent variable) with regard to characteristics of the patients (independent variables). Results A total of 418 individuals were registered in the clinic. Most individuals suffered from the neurotic, stress-related, and somatoform group of disorders ( n = 231, 39.5%). More than halves were self-referred; most were referred from the internal medicine and allied departments. Being male, having at least graduate degree (χ 2 df(1) = 4.25 to 6.79, p < 0.05), suffering from organic mental-, psychotic-, and recurrent affective-disorders, and positive family history (χ 2 df(1) = 4.91 to 21.76, p < 0.05 to <0.001) along with first treatment attempt or previous treatment from the traditional healers, and absence of co-occurring medical illness were associated with self-referral (vs. referred by others) (χ 2 df(1) = 4.64 to 17.6, p < 0.05 to <0.001). Conclusions GHS has a characteristic referral pattern. The referral patterns of the patients for various psychiatric problems are determined by their sociodemographic, illness, and cultural characteristics; particularly, poor mental health literacy (among the patients-caregivers), stigma related to mental disorders, and unavailability of the mental health services act as major determinants. Sensitizing the patients-caregivers and health-care professionals concerning this could facilitate an early engagement with the psychiatric treatment. Future research needs to explore this phenomenon in greater detail, maybe by qualitative methods.

The Effect of Clinical Nurses' Critical Thinking Disposition and Communication Ability on Patient Safety Competency

Purpose: This study was conducted to identify the influence of critical thinking disposition and communication ability on patient safety competence among clinical nurses. Methods: A cross-sectional descriptive study was conducted using a self-reported questionnaire. In total, 139 nurses were recruited from a tertiary care hospital and general hospital in Gyeonggi Province. Data were collected from March 5, 2019 to March 29, 2019 and analyzed using descriptive statistics, independent t-test, one-way analysis of variance, the Scheffé test, Pearson’ correlation coefficients, and hierarchical multiple regression with SPSS version 25.0. Results: The item mean score for patient safety competence was 3.83±0.40 (range, 1~5). Clinical nurses who were female, older, had higher education, and had more clinical experiences showed higher patient safety competence. Hierarchical multiple regression analysis showed that healthy skepticism and objectivity (as subscales of clinical thinking disposition) and communication ability explained 28% and 3% of variance in patient safety competence; the model predicted approximately 38% of the variance in patient safety competence (F=6.69, p&lt;.001). Conclusion: Clinical nurses’ patient safety competence was associated with healthy skepticism and objectivity, among the subscales of clinical thinking disposition, and communication ability. These were also found to be the major factors that influenced patient safety competence. Thus, it is necessary to develop educational programs to improve clinical nurses’ critical thinking disposition and communication skills.

Prevalence and clinical presentation of adenoid hypertrophy among children attending at pediatric outpatient department of a tertiary care general hospital of Dhaka

Background: Adenoid hypertrophy (AH) and it consequences are common in the entire childhood period. This study was aimed to estimate the prevalence, to enumerate the presence of risk factors and pattern of presentations of AH among children attending at pediatric outpatient department.&#x0D; Methods: This cross-sectional study was conducted at the general pediatric outpatient department (OPD) of BIRDEM General Hospital-2 (Women and Children), Dhaka from January 2017 to December 2020. All the children aged 1-18 years attending the OPD who had known risk factors or sign-symptoms of AH were underwent a lateral nasopharyngeal x-ray to confirm the presence of enlarged adenoid. Those children who had enlarged adenoid were analyzed in this study.&#x0D; Results: A total of 20234 children attended the general pediatric OPD during the study period, of them, 463 had evidences of enlarged adenoid on lateral nasopharyngeal x-ray, giving a prevalence of 2.3%. The mean age of presentation was 100.6±58 months. Among the AH cases 86% had allergic sensitivity to house dust, 60% had allergic rhinitis, 55.5% had history of recurrent tonsillitis and 55.3% children were exposed to cigarette smoke especially at home. Most common presentation of AH was mouth breathing especially during sleep time (90.5%). Other common presenting features were nasal obstruction (83.6%), nasal discharge (73%), drooling of saliva (72.4%), daytime somnolence (65.2%) and snoring during sleep (61.8%). According to our study AH may be asymptomatic in 5% cases. However, it may be presented with complications such as OSA (obstructive sleep apnea) (26.6%), adenoid facies (13.8%) and otitis media with effusion with or without hearing impairment (12.5%). Eighty two (17.7%) need referral to ENT OPD for adenoidectomy. Most common indication for adenoidectomy was obstructive sleep apnea (41.5%).&#x0D; Conclusion: Prevalence of adenoid hypertrophy among children attending at pediatric outpatient department was 2.3%, of them 17.7% had indication for adenoidectomy. Allergic sensitivity to house dust was the most common risk factors. Most common two clinical presentations were mouth breathing and nasal obstruction and most common complication was obstructive sleep apnea.&#x0D; BIRDEM Med J 2022; 12(2): 111-116

Epidemiology and outcomes of ventilator-associated events in critically ill children: Evaluation of three different definitions.

Ventilator-associated pneumonia (VAP) is one of the most common healthcare-associated infections in pediatric intensive care units (PICUs), but its definite diagnosis remains controversial. The CDC Ventilator-Associated Event (VAE) module (validated in adults) constitutes a new approach for VAP surveillance. We described epidemiological characteristics of PICU VAE cases, investigated possible risk factors, and evaluated 3 different sets of diagnostic VAE criteria. This study was conducted in a PICU in a tertiary-care general hospital in northern Greece during 2017-2019. The study included patients aged 35 days-16 years who received mechanical ventilation. From medical records, we retrieved epidemiological data, clinical data, and laboratory characteristics as well as ventilator settings for our analysis. We assessed "oxygen deterioration" for the tier 1 CDC VAE module using 3 sets of diagnostic criteria: (1) CDC adult VAE criteria [increase of daily minimum fraction of inspired oxygen (FiO2) ≥ 0.2 or positive end expiratory pressure (PEEP) ≥ 3 cmH2O for 2 days], (2) the US pediatric VAE criteria [increase of FiO2 ≥ 0.25 or mean airway pressure (MAP) ≥ 4 cmH2O for 2 days], and (3) the European pediatric VAE criteria (increase of FiO2 ≥ 0.2 or PEEP ≥ 2 cmH2O for 1 day or increase of FiO2 ≥ 0.15 and PEEP ≥ 1 cm H2O for 1 day). Among 326 children admitted to the PICU, 301 received mechanical ventilation. The incidence rate according to the CDC adult VAE criteria was 4.7 per 1,000 ventilator days. For the US pediatric VAE criteria the incidence rate was 6 per 1,000 ventilator days. For the European pediatric VAE criteria the incidence rate was 9.7 per 1,000 ventilator days. These results revealed statistically significant correlation of all 3 algorithms with adverse outcomes, including mortality. All VAE algorithms were associated with higher mortality rates. Our findings highlight the need for a unified pediatric VAE definition to improve preventive strategies.

Factors associated with multidrug-resistant bacteria in healthcare-associated infections: a pediatric intensive care unit case-control study.

ABSTRACTObjective To investigate the prevalence of factors related to healthcare-associated infections, caused by multidrug-resistant bacteria, in a pediatric intensive care unit.Methods A retrospective case-control study conducted from January 1, 2007 to December 31, 2018, in São Paulo (SP), Brazil. The study was carried out at the pediatric intensive care unit of a high-complexity, tertiary care general hospital. The study included patients aged 1 month to 19 years, admitted to the pediatric intensive care unit, diagnosed as healthcare-associated infections.Results There was significant evidence of infection by multidrug-resistant bacteria associated with immunosuppressed patients (p<0.001), in whom the likelihood of multidrug-resistant bacteria infection was estimated to be nine-fold higher than among non-immunosuppressed patients (OR 8.97; 95%CI 2.69-29.94). In the analysis of multiple logistic regression model, we observed that immunosuppressed patients had an 8.5-fold higher chance of multidrug-resistant bacteria infection when compared to non-immunosuppressed patients (OR 8.48; 95%CI 2.54-28.35; p=0.001). There is evidence of association between the Case Group and presence of Gram-positive (p=0.007), coagulase-negative Staphylococcus (p<0.001), and Gram-negative (p=0.041) microorganisms.Conclusion The immunocompromised-state variable is a factor related to healthcare-associated infections caused by multidrug-resistant bacteria, and the Case Group presented higher proportions of Gram-positive microorganisms and coagulase-negative Staphylococcus.

Examining pulmonary TB patient management and healthcare workers exposures in two public tertiary care hospitals, Bangladesh.

Implementation of tuberculosis (TB) infection prevention and control (IPC) guidelines in public tertiary care general hospitals remain challenging due to limited evidence of pulmonary TB (PTB) patients' duration of hospital stay and management. To fill this evidence gap, this study examined adult PTB patient management, healthcare workers' (HCWs) exposures and IPC practices in two public tertiary care hospitals in Bangladesh.Between December 2017 and September 2019, a multidisciplinary team conducted structured observations, a hospital record review, and in-depth interviews with hospital staff from four adult medicine wards.Over 20 months, we identified 1,200 presumptive TB patients through the hospital record review, of whom 263 were confirmed PTB patients who stayed in the hospital, a median of 4.7 days without TB treatment and possibly contaminated the inpatients wards. Over 141 observation hours, we found a median of 3.35 occupants present per 10 m2 of floor space and recorded a total of 17,085 coughs and 316 sneezes: a median of 3.9 coughs or sneezes per 10 m2 per hour per ward. Only 8.4% of coughs and 21% of sneezes were covered by cloths, paper, tissues, or by hand. The HCWs reportedly could not isolate the TB patients due to limited resources and space and could not provide them with a mask. Further, patients and HCWs did not wear any respirators.The study identified that most TB patients stayed in the hospitals untreated for some duration of time. These PTB patients frequently coughed and sneezed without any facial protection that potentially contaminated the ward environment and put everyone, including the HCWs, at risk of TB infection. Interventions that target TB patients screening on admission, isolation of presumptive TB patients, respiratory hygiene, and HCWs' use of personal protective equipment need to be enhanced and evaluated for acceptability, practicality and scale-up.

Causes and Diagnostic Usefulness of Tryptase Measurements for Anaphylaxis in a Korean Tertiary Care General Hospital.

The causes of anaphylaxis in a general hospital may differ from those occurring in a community setting. Underlying diseases in admitted patients and vague presenting symptoms can make the diagnosis of anaphylaxis difficult. Serum tryptase measurements may provide valuable evidence for diagnosing anaphylaxis in admitted patients. This study was designed as a retrospective study of 53 patients with an anaphylaxis episode at a Korean tertiary care general hospital. Tryptase levels were measured at baseline and different time points from the onset of anaphylaxis. Drugs (42 cases; 79.2%) and foods (10 cases; 18.9%) were the most common causes of anaphylaxis. In drug-induced anaphylaxis, antibiotics (24.5%), anticancer medications, which included monoclonal antibodies (22.6%), and contrast agents (11.3%) were the most frequent causes. The muscle relaxant eperisone (5.7%), neuromuscular blocking agent rocuronium (5.7%), and its antagonist sugammadex (3.8%) were other frequent triggering agents. Wheat-dependent exercise-induced anaphylaxis was the most common entity in food-induced anaphylaxis. Tryptase concentrations were higher in patients with higher grades of anaphylaxis, as well as in accidental anaphylaxis, compared to meticulously provoked anaphylaxis. Overall diagnostic sensitivity was higher for tryptase algorithm criteria (≥[1.2×baseline+2] µg/L: 71.4%) than for abnormal tryptase level criteria (≥11.4 µg/L: 52.8%). The triggers of anaphylaxis in a Korean tertiary care hospital were diverse, including beta-lactam antibiotics, anticancer medications, contrast medias, eperisone, nonsteroidal anti-inflammatory drugs, rocuronium, sugammadex, and wheat. Tryptase measurements provided valuable evidence for diagnosis, and the sensitivity of algorithm criteria was superior to that of the abnormal value criteria.

Development and Validation of a Scale to Measure Anxiety Specific to Pregnancy During the COVID-19 Pandemic: The Antenatal COVID-19 Anxiety Scale.

Objective: In the context of the coronavirus disease 2019 (COVID-19) pandemic, anxiety during pregnancy should be assessed from a composite context of anxiety/fear of COVID-19 infection and pregnancy-specific anxiety. The objective of this study was to develop and validate a scale that measures anxiety related to situations specific to pregnancy during the COVID-19 pandemic-the Antenatal COVID-19 Anxiety (AnCAn) Scale.Methods: Items were generated based on a literature review and focused group discussions. Face and content validation was completed. Data were collected from 557 pregnant women attending antenatal clinics of 5 tertiary care general hospitals in India. An exploratory factor analysis was conducted to measure structural validity and to identify latent factors. Screening accuracy was assessed using scores on the 7-item Generalized Anxiety Disorder scale. Data were collected between July and October 2020.Results: The principal component analysis showed that the 12 items of the scale significantly loaded onto 2 latent factors, with Eigen values of 6.575 and 1.213, respectively. Factor solution showed that 6 items correlated with each of the 2 factors. Both sensitivity and specificity of AnCAn total and subscores were > 70%.Conclusions: We conclude that the AnCAn Scale holds good psychometric properties, and it identifies and distinguishes 2 latent factors: (1) anxiety related to acquiring infection and (2) anxiety related to spreading infection and social role obligations, which are compositely related to anxiety specific to COVID-19 and pregnancy.

Machine learning method intervention: Determine proper screening tests for vestibular disorders

ObjectiveTo evaluate the performance of different vestibular indicators in disease classification based on machine learning method. MethodsThis study use retrospective analysis of the vertigo outpatient database from a tertiary care general hospital. 1491 patients with definite clinical diagnoses were enrolled in this study. Spontaneous nystagmus, head-shaking nystagmus, positional nystagmus, unilateral weakness in caloric test, and gain and saccade in video head impulse test (vHIT) were recorded as variables. Diagnoses were mainly reorganized as acute vestibular syndrome, episodic vestibular syndrome, and chronic vestibular syndrome. The trained random forest model was applied based on exploratory data analysis results. ResultsRandom forest accuracies on acute, episodic, and chronic vestibular syndrome are 90%, 81.74%, and 91.3%, respectively. The most important features in acute vestibular syndrome are spontaneous nystagmus, and vHIT variables. In episodic vestibular syndrome, unilateral weakness in caloric test, gain and saccades on lateral semicircular canal are the top three parameters. Lateral vHIT gain, head-shaking nystagmus, and unilateral weakness in caloric test are the main parameters on chronic vestibular syndrome. In acute vestibular syndrome, spontaneous nystagmus and vHIT make major contributions in vestibular disorders distinction. When the disease course prolongation, unilateral weakness and head-shaking nystagmus become increasingly important. ConclusionFast clinical test sets including spontaneous nystagmus, head shaking nystagmus, and vHIT should be the first consideration in screening vestibular disorders.
