An evaluation of a Stenotrophomonas maltophilia outbreak due to commercial arterial blood gas collection kit.

BACKGROUND: Stenotrophomonas maltophilia is a gram-negative bacterium that can cause hospital infections and outbreaks within hospitals. This study aimed to evaluate an outbreak of Stenotrophomonas maltophilia, caused by ready-to-use commercial syringes containing liquid lithium and heparin for arterial blood gas collection in a university hospital. METHODS: Upon detecting an increase in Stenotrophomonas maltophilia growth in blood cultures between 15.09.2021 and 19.11.2021, an outbreak analysis and a case-control study (52 patients for the case group, 56 patients for the control group) were performed considering risk factors for bacteremia. Samples from possible foci for bacteremia were also cultured. Growing bacteria were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The genetic linkage and clonal relationship isolates were investigated with pulsed-field gel electrophoresis (PFGE) in the reference laboratory. RESULTS: In the case-control study, the odds ratio for the central venous catheter [3.38 (95% confidence interval [CI]: 1.444, 8.705 ; p = 0.006)], for surgery [3.387 (95% confidence interval [CI]: 1.370, 8.373 ; p = 0.008)] and for arterial blood gas collection history [18.584 (95% confidence interval [CI]:4.086, 84.197; p < 0.001)] were identified as significant risk factors. Stenotrophomonas maltophilia growth was found in ready-to-use commercial syringes used for arterial blood gas collection. Molecular analysis showed that the growths in the samples taken from commercial syringes and the growths from blood cultures were the same. It was decided that the epidemic occurred because the method for sterilization of heparinized liquid preparations were not suitable. After discontinuing the use of the kits with this lot number, the outbreak was brought under control. CONCLUSIONS: According to our results, disposable or sterile medical equipment should be included as a risk factor in outbreak analyses. The method by which injectors containing liquids, such as heparin, are sterilized should be reviewed. Our study also revealed the importance of the cooperation of the infection control team with the microbiology laboratory.

Concomitant human papillomavirus (HPV) vaccination and screening for elimination of HPV and cervical cancer.

HPV vaccination with concomitant HPV-based screening of young women has been proposed for faster cervical cancer elimination. We describe the baseline results of a population-based trial of this strategy to reduce the incidence of HPV. All 89,547 women born 1994-1999 and resident in the capital region of Sweden were personally invited to concomitant HPV vaccination and HPV screening with 26,125 women (29.2%) enrolled between 2021-05-03 and 2022-12-31. Baseline HPV genotyping of cervical samples from the study participants finds, compared to pre-vaccination prevalences, a strong decline of HPV16 and 18 in birth cohorts previously offered vaccination, some decline for cross-protected HPV types but no decline for HPV types not targeted by vaccines. Our dynamic transmission modelling predicts that the trial could reduce the incidence of high-risk HPV infections among the 1994-1998 cohorts by 62-64% in 3 years. Baseline results are prevalences of HPV infection, validated transmission model projections, and power estimates for evaluating HPV incidence reductions at follow-up (+/-0.1% with 99.9% confidence). In conclusion, concomitant HPV vaccination and HPV screening appears to be a realistic option for faster cervical cancer elimination.

Surveillance of carbapenem-resistant Klebsiella pneumoniae and Escherichia coli in perianal swab samples.

Our study aimed to detect carbapenem-resistant Klebsiella pneumoniae (CRKP) and/or carbapenem-resistant Escherichia coli in perianal swab samples, exploring their link to bloodstream infections (BSIs) in a tertiary-care university hospital. CRKP-related BSIs ranged from 3.7% to 9.58%, emphasizing the need to understand local risk factors for effective infection control.

Treatment initiation rates of patients with positive anti-hepatitis C virus results in tertiary hospitals in Turkey.

INTRODUCTION: The aim of this national, multicenter, cross-sectional, retrospective chart review study was to determine the proportion of patients in Turkey who received hepatitis C virus (HCV) treatment after receiving positive anti-HCV results during HCV screening. METHODOLOGY: Data related to patients' demographics, laboratory results, time interval from obtaining a positive anti-HCV result to treatment initiation, specialty of the physician requesting anti-HCV screening, and type of hospital were analyzed. RESULTS: Among 1,000 patients who received a positive anti-HCV result, 50.3% were male and 78.5% were screened for HCV-RNA. Among HCV-RNA screened patients, 54.8% (n = 430) had a positive result. Among patients who tested positive for HCV-RNA, 72.8% received HCV treatment in line with their positive anti-HCV results. The median time from obtaining a positive anti-HCV result to initiation of HCV treatment was 91.0 days (interquartile range 42.0 to 178.5). Non-surgical branches requested HCV-RNA testing more frequently than surgical branches (p < 0.001). The rate of access to HCV treatment was higher among patients screened in university hospitals than among patients screened in training and research hospitals (p < 0.001). CONCLUSIONS: Our results indicate a higher rate of treatment initiation among patients with HCV infection than is described in the published literature. Furthermore, the time from screening to treatment initiation was considerably shorter compared with other international studies. However, since HCV-RNA testing was not requested in a significant portion of patients with a positive anti-HCV test result, there might be a large patient population with HCV who do not receive treatment.

Suicide Probability Among Patients With Schizophrenia and Bipolar Disorder.

PURPOSE: To evaluate the possibility of suicide and related factors among individuals with schizophrenia and bipolar disorder (BD). METHOD: Data were collected for 270 individuals registered in a community mental health center using the Suicide Probability Scale (SPS). Subsequently, t test and multiple linear regression analyses were conducted on independent samples. RESULTS: There was no statistically significant difference found between mean SPS scores of participants with schizophrenia and BD. However, hostility subscale mean scores of participants with schizophrenia were higher than those of participants with BD, and the difference was statistically significant. Sex, family history of mental illness, need for help with medication, suicidal ideation in the past 10 days, and number of suicide attempts were important predictors of suicide probability. CONCLUSION: Individuals with schizophrenia and BD and in remission should be evaluated periodically for the possibility of suicide.

Human papillomavirus negative high grade cervical lesions and cancers: Suggested guidance for HPV testing quality assurance.

BACKGROUND: Some high-grade cervical lesions and cervical cancers (HSIL+) test negative for human papillomavirus (HPV). The HPV-negative fraction varies between 0.03 % and 15 % between different laboratories. Monitoring and extended re-analysis of HPV-negative HSIL+ could thus be helpful to monitor performance of HPV testing services. We aimed to a) provide a real-life example of a quality assurance (QA) program based on re-analysis of HPV-negative HSIL+ and b) develop international guidance for QA of HPV testing services based on standardized identification of apparently HPV-negative HSIL+ and extended re-analysis, either by the primary laboratory or by a national HPV reference laboratory (NRL). METHODS: There were 116 initially HPV-negative cervical specimens (31 histopathology specimens and 85 liquid-based cytology samples) sent to the Swedish HPV Reference Laboratory for re-testing. Based on the results, an international QA guidance was developed through an iterative consensus process. RESULT: Standard PCR testing detected HPV in 55.2 % (64/116) of initially "HPV-negative" samples. Whole genome sequencing of PCR-negative samples identified HPV in an additional 7 samples (overall 61.2 % HPV positivity). Reasons for failure to detect HPV in an HSIL+ lesion are listed and guidance to identify cases for extended re-testing, including which information should be included when referring samples to an NRL are presented. CONCLUSION: Monitoring the proportion of and reasons for failure to detect HPV in HSIL+ will help support high performance and quality improvement of HPV testing services. We encourage implementation of QA strategies based on re-analysis of "HPV negative" HSIL+ samples.

Analysis of dementia research trends in nursing using text mining approach.

This research aimed to analyze dementia research trends in nursing using a text mining approach. In this study, text mining approach was used to analyze the studies on dementia in the field of nursing around the world. In this study, summaries of all available publications in English between the years 1990-2023 were extracted from the database and transferred to an Excel table by using the 'Nursing' AND 'Dementia' query from the Thomson Reuters-ISI Web of Science database. According to the results of this research, a total of 21 concept groups were identified, four of which were the most important. It was determined that the most frequently used word in all of the studies obtained from the database was 'cost'. In this direction, scientific research on dementia in the field of nursing can be planned by evaluating the most frequently used concepts.

The effect of position change and abdominal massage on anxiety, pain and distension after colonoscopy: A randomized clinical trial.

CONTEXT: Pain, abdominal distention, and anxiety are major risk factors encountered after colonoscopy. Complementary and alternative treatments, such as abdominal massage and position change, are used to reduce the associated risk factors. OBJECTIVE: To determine the effect of position change and abdominal massage on anxiety, pain, and distension after colonoscopy. DESIGN: A randomized three-group experimental trial. SETTING AND PARTICIPANTS: This study was conducted with 123 patients who underwent colonoscopy at the endoscopy unit of a hospital located in western Turkey. METHODS: Three groups were formed: two interventional (abdominal massage and position change) and one control, each including 41 patients. Data were gathered using a personal information form, pre- and post-colonoscopy measurement form, the Visual Analog Scale (VAS), and the Spielberger State-Trait Anxiety Inventory. Pain and comfort levels, abdominal circumference values, and vital signs of the patients were measured at four evaluation times. RESULTS: In the abdominal massage group, the VAS pain scores and abdominal circumference measurements decreased the most and the VAS comfort scores increased the most 15 min after the patients were taken to the recovery room (p<0.05). Furthermore, bowel sounds were heard, and bloating was relieved in all patients in both intervention groups 15 min after they were taken to the recovery room. CONCLUSIONS: Abdominal massage and position change can be considered effective interventions for relieving bloating and facilitating flatulence after colonoscopy. Moreover, abdominal massage can be a powerful method for reducing pain and abdominal circumference and increasing patient comfort.

First international proficiency study on human papillomavirus testing in cervical cancer screening.

BACKGROUND: Although cervical screening using Human Papillomavirus (HPV) testing is globally recommended public health policy, there has been no international proficiency studies specifically targeting HPV testing for cervical screening. OBJECTIVE: To obtain the first global overview of the current proficiency of HPV testing services for cervical cancer screening. STUDY DESIGN: A coded proficiency panel of 12 samples containing HPV types 16, 18, 31, 33, 45, 52, 58 or 35/39/51/56/59/68 in human DNA in varying amounts as well as control. Datasets detecting at least a) 10 International Units (IU) of HPV16 and 18, b) 1000 IU of HPV types 31, 33, 45, 52, 58 and c) having no false positives were considered proficient. RESULTS: In total, 84 laboratories worldwide submitted 158 datasets (some laboratories used >1 HPV testing platform). Of those, 122 (77%) were 100% proficient. Only 14/158 datasets (9%) contained false positive results. Comparison of results with assays approved by the Food and Drug Administration (FDA) suggest that future proficiency requirements should also accommodate assays detecting only 100 IU of HPV16/18. A pool of low oncogenicity HPV types that contributed very little to sensitivity, but adversely affected specificity, was detectable by most datasets. CONCLUSION: Internationally recognized proficiency studies of HPV screening, traceable to international standards, provided an overview of current testing performance. There was a high level of proficiency in terms of sensitivity and few false positives, but specificity was not optimal and further research on optimal specificity of HPV screening tests may be warranted.

Developing the better and effective nursing education for improving transcultural nursing skills cultural competence and cultural sensitivity assessment tool (BENEFITS-CCCSAT).

BACKGROUND: A clear need for the development of new comprehensive, reliable, sensitive and valid measurement tools to adequately asses the cultural competence and cultural sensitivity of nursing students exists. This study aimed to develop a new measurement tool to assess the nursing students' cultural competence and sensitivity. METHODS: This cross-sectional, instrument development study's first phase included postgraduate nursing students (n = 60) for the piloting study, and the second one included undergraduate nursing students (n = 459) for the main survey. This study used two data collection forms: The Student Descriptive Information Form and the Better and Effective Nursing Education for Improving Transcultural Nursing Skills Cultural Competence and Cultural Sensitivity Assessment Tool (BENEFITS-CCCSAT) draft. The content validity index was calculated using the Davis method. Cronbach's α coefficient and the item total correlation were calculated during the reliability analysis. The Kaiser-Meyer-Olkin (KMO) coefficient test, Bartlett significance test, and explanatory factor analysis (EFA) were used to evaluate the validity of the assessment tool. RESULTS: Scale validity and reliability analyses showed that the BENEFITS-CCCSAT included 26 items and five sub-dimensions: respect for cultural diversity; culturally sensitive communication; achieving cultural competence; challenges and barriers in providing culturally competent care; and perceived meaning of cultural care. CONCLUSION: The BENEFITS-CCCSAT appears to be a valid and reliable instrument for measuring the cultural sensitivity and cultural competence of nursing students. This can be of great use, especially before attending clinical areas, and can offer both students and faculty reliable information to promote reflective and critical thinking, especially in areas where improvement is needed.

Assessment of Human Papillomavirus Non-16/18, Type-Specific Risk for Cervical Intraepithelial Neoplasia Grade 3 or Worse Among Women With Cervical Atypical Glandular Cells.

OBJECTIVE: To evaluate the risk for cervical intraepithelial neoplasia grade 3 (CIN 3) or worse (including adenocarcinoma in situ [AIS] and invasive cervical cancer) associated with non-16/18 human papillomavirus (HPV) types (other HPV) among women with atypical glandular cells (AGC) in cervical cytology. METHODS: This population-based cohort study evaluates the risk of CIN 3 or worse associated with other HPV types. Human papillomavirus genotyping was performed on Pap tests collected in Sweden from 341 women with AGC that were positive for other HPV types from February 17, 2014, to December 31, 2018. The women were followed for histopathologic outcomes using comprehensive registry linkages until December 31, 2019. Cumulative incidence proportions of CIN 3 or worse by specific HPV type were calculated using 1-minus Kaplan-Meier function. Hazard ratios (HRs) for CIN 3 or worse were generated using multivariate Cox regression. RESULTS: Of 341 women, 134 (39.3%) had CIN 3-AIS, but there were only five (1.5%) women in the cohort with invasive cervical cancer. Human papillomavirus 45 preceded 80.0% of invasive cervical cancer cases. Among women positive for HPV33, 82.9% (95% CI 58.0-97.3%) had CIN 3 or worse during follow-up. Positivity for HPV31 conferred the highest HR for CIN 3 or worse relative to other types, both in primary cytology and primary HPV screening (HR 2.71, 95% CI 1.47-5.00 and HR 3.41, 95% CI 1.95-5.96, respectively). CONCLUSION: Among non-16/18 HPV types in AGC, HPV31 and 33 had the highest risk for CIN 3 or worse, whereas most of the women with invasive cancer were positive for HPV45. Extended HPV genotyping may be helpful for the management of AGC.

Accumulation of tissue-resident natural killer cells, innate lymphoid cells, and CD8+ T cells towards the center of human lung tumors.

Lung cancer is a leading cause of cancer-related death worldwide. Despite recent advances in tissue immunology, little is known about the spatial distribution of tissue-resident lymphocyte subsets in lung tumors. Using high-parameter flow cytometry, we identified an accumulation of tissue-resident lymphocytes including tissue-resident NK (trNK) cells and CD8+ tissue-resident memory T (TRM) cells toward the center of human non-small cell lung carcinomas (NSCLC). Chemokine receptor expression patterns indicated different modes of tumor-infiltration and/or residency between trNK cells and CD8+ TRM cells. In contrast to CD8+ TRM cells, trNK cells and ILCs generally expressed low levels of immune checkpoint receptors independent of location in the tumor. Additionally, granzyme expression in trNK cells and CD8+ TRM cells was highest in the tumor center, and intratumoral CD49a+CD16- NK cells were functional and responded stronger to target cell stimulation than their CD49a- counterparts, indicating functional relevance of trNK cells in lung tumors. In summary, the present spatial mapping of lymphocyte subsets in human NSCLC provides novel insights into the composition and functionality of tissue-resident immune cells, suggesting a role for trNK cells and CD8+ TRM cells in lung tumors and their potential relevance for future therapeutic approaches.

Effects of COVID-19 pandemic on healthcare-associated infections, antibiotic resistance and consumption rates in intensive care units.

Purpose: This paper aimed to evaluate the effects of the COVID-19 pandemic on healthcare-associated infections (HAIs), antibiotic resistance and consumption rates in intensive care units (ICUs) of a tertiary care university hospital. Patients and Methods: Between 1 January 2018 and 31 December 2021, adult patients diagnosed with HAIs in ICUs were investigated retrospectively. Patients were divided into pre-pandemic (2018-2019) and pandemic periods (2020-2021). Antibiotic consumption index was calculated via using the formula of (total dose (grams)/defined daily dose (DDD) x total patient days) x1000. A p value below 0.05 was accepted as statistically significant. Results: The incidence of HAIs (per 1000 patient days) in the ICU of COVID-19 patients was 16.59, while it was 13.42 in the other ICUs during the pandemic period (p=0.107). The bloodstream infection (BSI) incidence was 3.32 in the pre-pandemic period and 5.41 in the pandemic period in ICUs other than the ICU of COVID-19 patients (p<0.001). In the pandemic period, the BSI incidence rate was significantly higher in the ICU of COVID-19 patients than in the other ICUs (14.26 vs 5.41, p<0.001). Central venous catheter bloodstream infections incidence rate was 4.72 in the pre-pandemic and 7.52 in the pandemic period in ICUs other than the ICU of COVID-19 patients (p=0.0019). During the pandemic period, the bacteraemia episode rates of Acinetobacter baumannii (5.375 vs 0.984, p<0.001), Enterococcus spp. (1.635 vs 0.268, p<0.001) and Stenotrophomonas maltophilia (3.038 vs 1.297, p=0.0086) in the ICU of COVID-19 patients were significantly found higher than others. The extended-spectrum beta-lactamase (ESBL) positivity rates for Klebsiella pneumoniae and Escherichia coli were 61% and 42% in the pre-pandemic period; 73% and 69% in the pandemic period in ICUs other than the ICU of COVID-19 patients (p>0.05). In the pandemic period, the ESBL positivity rates for K. pneumoniae and E. coli were 83% and 100% in the ICU of COVID-19 patients, respectively. Meropenem (p<0.001), teicoplanin (p<0.001) and ceftriaxone (p<0.001) consumptions were increased while ciprofloxacin (p=0.003) consumption was decreased in all ICUs after the pre-pandemic period. Conclusions: BSI and CVCBSI incidence rates were significantly increased in all ICUs after the COVID-19 pandemic in our hospital. Bacteraemia episode rates of A. baumannii, Enterococcus spp. and S. maltophilia in ICU of COVID-19 patients were significantly found higher than others. In addition, meropenem, teicoplanin and ceftriaxone consumptions were increased in all ICUs after the COVID-19 pandemic.

Spiritual Well-Being and Psychological Well-Being Among Hemodialysis Patients in Turkey: A Descriptive and Correlational Study.

This study aimed to determine the psychological and spiritual well-being of hemodialysis patients in Turkey. This descriptive and correlational study included 86 hemodialysis patients. Data were collected using the Spiritual Well-Being Scale and Psychological Well-Being Scale. There was a positive correlation between spiritual and psychological well-being (r = 0.315, p = 0.003). Psychological well-being and age explained 39% of total variance (F = 7.593, p = 0.001). In conclusion, there should be provided individualized spiritual care and counseling to improve the psychological well-being of hemodialysis patients.

We present a 57-year-old male diagnosed with systemic HGA and lung involvement, who had lived in Benin. A possible tick bite had been reported in his history. There was a dramatic response to treatment.

Determination of Health Anxiety and Resilience Levels in Patients with Fibromyalgia Syndrome and Rheumatoid Arthritis During SARS-CoV-2 Pandemic: A Case-Control Study.

Background: Fibromyalgia Syndrome and Rheumatoid Arthritis are chronic diseases associated with pain. These diseases reduce the patient's quality of life and cause psychological problems. The study aimed to determine health anxiety and resilience levels in patients with fibromyalgia syndrome and rheumatoid arthritis during the severe acute respiratory syndrome coronavirus 2 pandemic. Methods: This case-control study conducted in Central Anatolia Region, Turkey, included 180 participants (60 patients with fibromyalgia syndrome, 60 patients with rheumatoid arthritis, and 60 healthy subjects). Data were collected using the Brief Resilience Scale and Health Anxiety Scale. Pain intensity was assessed using the Visual Analog Scale. Results: Resilience was significantly higher in healthy controls than in the fibromyalgia syndrome and rheumatoid arthritis groups (P < .001). Resilience was also higher in the rheumatoid arthritis group than fibromyalgia syndrome (P < .001) group. Hypersensitivity to somatic symptoms and anxiety, negative results of diseases, and total scores of Health Anxiety Scale were significantly higher in the fibromyalgia syndrome and rheumatoid arthritis groups than healthy controls (P < .001). Also, Health Anxiety Scale scores in the fibromyalgia syndrome group were higher than the rheumatoid arthritis group (P < .001). There was a very strong and negative correlation between the participants' resilience and health anxiety levels (r = -0.818, P < .001). The most important predictors of resilience were hypersensitivity to somatic symptoms and anxiety (r = -0.335, P < .001), the group (r = 0.302, P = .003), the pain intensity (r = -0.169, P = .043), and the negative consequences of the disease (r = -.149, P = .038). The hypersensitivity to somatic symptoms and anxiety, the Visual Analog Scale, and the negative consequences of the disease were negatively correlated with resilience. But there was a positive correlation between fibromyalgia syndrome and rheumatoid arthritis groups and resilience. Conclusions: Patients with fibromyalgia syndrome and rheumatoid arthritis have low resilience and high health anxiety. The interventions should be planned to increase resilience and decrease the health anxiety of patients with fibromyalgia syndrome and rheumatoid arthritis.
