ABSTRACT

BACKGROUND: Nurses play a vital role in providing round-the-clock care to patients, but the challenges associated with working night shifts can have significant implications for their well-being and quality of life.

METHODS: This cross-sectional study aimed to investigate the impact of night shift stress and sleep disturbance on the quality of life among nurses working in Palestine Red Crescent Society and Al-Ahli Hospital. Convenience sampling was used to recruit 189 full-time registered nurses with at least one year of job experience. The participants completed a questionnaire assessing night shift stress, sleep disturbance, and quality of life. Descriptive statistics, correlation analysis, and path analysis were conducted to analyze the data.

RESULTS: The results reveal that quality of life has positive and low relationship with both night shift stress and sleep disturbances. Results also reveal that night shift stress had a direct negative impact on the quality of life of nurses. Sleep disturbance was found to mediate the relationship between night shift stress and quality of life, indicating that higher levels of night shift stress were associated with increased sleep disturbance, which, in turn, led to poorer quality of life outcomes.

CONCLUSION: These findings highlight the importance of addressing night shift stress and sleep disturbance among nurses to enhance their well-being and improve the quality of care provided to patients. In conclusion, this study contributes to the existing literature by demonstrating the detrimental effects of night shift stress and sleep disturbance on the quality of life of nurses. It emphasizes the importance of implementing interventions and creating supportive work environments that address the unique challenges faced by nurses working night shifts.

ABSTRACT

OBJECTIVE: To investigate whether prenatal fibrinogen (FIB) or other related factors could be utilized to evaluate the risk of postpartum hemorrhage (PPH).

METHODS: A retrospective study was conducted in a database from January 2015 to December 2019. A total of 128 patients were enrolled and evaluated with FIB, in which 55 patients were assigned to low FIB and 73 in normal FIB.

RESULTS: According to the volume of blood loss, the mean of the low FIB group (<4 g/L) was markedly higher than that of the normal FIB group (≥4 g/L). Prenatal FIB was negatively correlated with PPH volume. The receiver operating characteristic (ROC) curve results indicated that the value of prenatal FIB was 0.701 to predict refractory PPH.

CONCLUSIONS: Prenatal FIB was significantly related to thrombin time (TT), which may be an independent factor to predict the coagulation state of prenatal pregnancy.

ABSTRACT

BACKGROUND: Pericardial effusion (PE) is a rare yet an important cause of child mortality due to collection of excess fluid in pericardial space. The study aimed to describe the PE profile in the national cardiac referral hospital, Addis Ababa, Ethiopia.

METHODS: The study employed cross-sectional study design for a 7-year review of childhood PE in Tikur Anbessa Specialized Hospital. Descriptive and analytic statistics were applied.

RESULTS: There were 17,386 pediatric emergency/ER admissions during the study period, and PE contributed to 0.47% of ER admissions. From 71 included subjects, 59% (42) were males with mean age of 7.8 ± 3.3 years. Cough or shortness of breath,73.2% (52) and fever or fast breathing, 26.7% (19), were the common presenting symptoms. The median duration of an illness before presentation was 14days (IQR: 8-20). The etiologies for pericardial effusion were infective (culture positive-23.9%, culture negative-43.6%, tuberculous-4.2%), hypothyroidism (4.2%), inflammatory (12.7%), malignancy (7%) or secondary to chronic kidney disease (1. 4%). Staphylococcus aureus was the most common isolated bacteria on blood culture, 12.7% (9) while the rest were pseudomonas, 7% (5) and klebsiella, 4.2% (3). Mild, moderate and severe pericardial effusion was documented in 22.5% (16), 46.5% (33), and 31% (22) of study subjects, respectively. Pericardial tamponade was reported in 50.7% (36) of subjects. Pericardial drainage procedure (pericardiocentesis, window or pericardiotomy) was performed for 52.1% (37) PE cases. The case fatality of PE was 12.7% (9). Pericardial drainage procedure was inversely related to mortality, adjusted odds ratio 0.11(0.01-0.99), p 0.049).

CONCLUSION: PE contributed to 0.47% of ER admissions. The commonest PE presentation was respiratory symptoms of around two weeks duration. Purulent pericarditis of staphylococcal etiology was the commonest cause of PE and the case fatality rate was 12.7%. Pericardial drainage procedures contributed to reduction in mortality. All PE cases should be assessed for pericardial drainage procedure to avoid mortality.

ABSTRACT

BACKGROUND: Intestinal parasitic infections can harm health by causing malnutrition, anemia, impaired growth and cognitive development, and alterations in microbiota composition and immune responses. Therefore, it is crucial to examine stool samples to diagnose parasitic infections. However, the traditional microscopic detection method is time-consuming, labor-intensive, and dependent on the expertise and training of microscopists. Hence, there is a need for a low-complexity, high-throughput, and cost-effective alternative to labor-intensive microscopic examinations.

METHODS: This study aimed to compare the performance of a fully automatic digital feces analyzer, Orienter Model FA280 (People’s Republic of China) with that of the formalin-ethyl acetate concentration technique (FECT). We assessed and compared the agreement between the FA280 and the FECT for parasite detection and species identification in stool samples. The first part of the study analyzed 200 fresh stool samples for parasite detection using the FECT and FA280. With the FA280, the automatic feces analyzer performed the testing, and the digital microscope images were uploaded and automatically evaluated using an artificial intelligence (AI) program. Additionally, a skilled medical technologist conducted a user audit of the FA280 findings. The second set of samples comprised 800 preserved stool samples (preserved in 10% formalin). These samples were examined for parasites using the FECT and FA280 with a user audit.

RESULTS: For the first set of stool samples, there was no statistically significant difference in the pairwise agreements between the FECT and the FA280 with a user audit (exact binomial test, P = 1). However, there were statistically significant differences between the pairwise agreements for the FECT and the FA280 with the AI report (McNemar’s test, P < 0.001). The agreement for the species identification of parasites between the FA280 with AI report and FECT showed fair agreement (overall agreement = 75.5%, kappa [κ] = 0.367, 95% CI 0.248-0.486). On the other hand, the user audit for the FA280 and FECT showed perfect agreement (overall agreement = 100%, κ = 1.00, 95% CI 1.00-1.00). For the second set of samples, the FECT detected significantly more positive samples for parasites than the FA280 with a user audit (McNemar’s test, P < 0.001). The disparity in results may be attributed to the FECT using significantly larger stool samples than those used by the FA280. The larger sample size used by the FECT potentially contributed to the higher parasite detection rate. Regarding species identification, there was strong agreement between the FECT and the FA280 with a user audit for helminths (κ = 0.857, 95% CI 0.82-0.894). Similarly, there was perfect agreement for the species identification of protozoa between the FECT and the FA280 with user audit (κ = 1.00, 95% CI 1.00-1.00).

CONCLUSIONS: Although the FA280 has advantages in terms of simplicity, shorter performance time, and reduced contamination in the laboratory, there are some limitations to consider. These include a higher cost per sample testing and a lower sensitivity compared to the FECT. However, the FA280 enables rapid, convenient, and safe stool examination of parasitic infections.

ABSTRACT

BACKGROUND: Prolonged prehospital time is a major global problem in the emergency medical system (EMS). Although factors related to prolonged on-scene times (OSTs) have been reported in patients with trauma and critical medical conditions, those in patients with minor diseases or injuries remain unclear. We examined factors associated with prolonged OSTs in patients with minor diseases or injuries.

METHODS: This population-based observational study used the ambulance transportation and request call record databases of the Higashihiroshima Fire Department, Japan, between January 1, 2016, and December 31, 2022. The participants were patients with minor diseases or injuries during the study period. We performed a multivariable logistic regression analysis with robust error variance to examine the association between patient age, sex, severity, accident type, date and time of ambulance call, and the coronavirus disease 2019 (COVID-19) pandemic with prolonged OSTs. Prolonged OST was defined as ≥ 30 min from the ambulance arrival at the scene to departure.

RESULTS: Of the 60,309 people transported by ambulance during the study period, 20,069 with minor diseases or injuries were included in the analysis. A total of 1,241 patients (6.2%) experienced prolonged OSTs. Fire accidents (adjusted odds ratio [aOR]: 7.77, 95% confidence interval [CI]: 3.82-15.79), natural disasters (aOR: 28.52, 95% CI: 2.09-389.76), motor vehicle accidents (aOR: 1.63, 95% CI: 1.30-2.06), assaults (aOR: 2.91, 95% CI: 1.86-4.53), self-injuries (aOR: 5.60, 95% CI: 3.37-9.32), number of hospital inquiries ≥ 4 (aOR: 77.34, 95% CI: 53.55-111.69), and the COVID-19 pandemic (aOR: 2.01, 95% CI: 1.62-2.50) were associated with prolonged OSTs. Moreover, older and female patients had prolonged OSTs (aOR: 1.18, 95% CI: 1.01-1.36 and aOR: 1.12, 95% CI: 1.08-1.18, respectively).

CONCLUSIONS: Older age, female sex, fire accidents, natural disasters, motor vehicle accidents, assaults, self-injuries, number of hospital inquiries ≥ 4, and the COVID-19 pandemic influenced prolonged OSTs among patients with minor diseases or injuries. To improve community EMS, we should reconsider how to intervene with potentially modifiable factors, such as EMS personnel performance, the impact of the presence of allied services, hospital patient acceptance systems, and cooperation between general emergency and psychiatric hospitals.

ABSTRACT

OBJECTIVES: Studies have demonstrated that high-speed jaw-opening exercises are effective in improving swallowing function. However, there has been no objective tool available for monitoring jaw-opening pace. This study aimed to develop an objective tool for monitoring and validating jaw-opening pace and compare it between young and old ages from different age groups.

MATERIALS AND METHODS: A load cell plug-in jaw pad connected to an automatic recording and analysis system was used to record jaw-opening motions for offline analysis. We recruited 58 healthy volunteers from different age groups (20-39 y/o; 40-59y/o; 60-79y/o). During a 2-min recording session, each participant was instructed to fully open and close their jaw as quickly as possible while wearing a sensor. Bland-Altman plot, paired t-test and Pearson’s correlation test were used to compare the number of jaw-opening motions between manual counting and automatic software analysis. The number of jaw-opening motions during the 2-min recording was compared between the three age groups.

RESULTS: Automated analysis of jaw-opening pace was efficient and equally comparable with the traditional manual counting method across the three age groups. A declining trend in jaw-opening pace among the old age group was found but with no statistically significant difference.

CONCLUSIONS: A jaw-opening motion monitoring tool with reliable automatic pace analysis software was validated in young and old ages. The jaw-opening pace demonstrated a tendency to decline with age.

CLINICAL RELEVANCE: This monitoring tool can also be used to provide visual feedback during jaw-opening motion training in pace control.

ABSTRACT

PURPOSE: To predict recurrence and progression in non-muscle-invasive bladder cancer (NMIBC) patients receiving bacillus Calmette-Guérin (BCG), we evaluated circulating basophils as a biomarker that could be detected from the complete blood count.

PATIENTS AND METHODS: We use a pooled cohort of patients from the Centre Hospitalier Universitaire de Québec-Université Laval (2016-2020) and the Vancouver General Hospital (2010-2018) where a complete blood count was available before transurethral resection of bladder tumor (TURBT) of a high-grade NMIBC and subsequent BCG. Descriptive statistics described the cohort based on the dichotomous presence or absence of basophils on the complete blood count. Kaplan-Meier estimates and a log-rank test compared recurrence-free survival (RFS) and progression-free survival (PFS), with multivariable cox regression analysis used to estimate proportional hazard ratios.

RESULTS: The study cohort included 261 patients, with a median follow-up of 31.5 months (interquartile range 18.1-45.0 months). The median age was 74.0 years and 16.8% were female. Circulating basophils were detectable in 49 (18.9%) patients. Both RFS and PFS were significantly lower in patients with detectable basophils. Multivariable analysis demonstrated detectable basophils were an independent predictor of both recurrence (HR = 1.85; 95% confidence interval [CI] 1.20-2.85; P = .01) and progression (HR = 2.29; 95% CI 1.14-4.60; P = .02).

CONCLUSION: Our results confirm that baseline levels of circulating basophils are an immunological biomarker to predict recurrence and progression of NMIBC.

ABSTRACT

INTRODUCTION: Prostate Specific Membrane Antigen (PSMA)-targeted radionucleotide therapy has been shown to cause dry mouth, but the oral manifestations of PSMA-targeted immunotherapy have not been extensively studied. The aim of this study was to describe and quantify the oral manifestations of PSMA-targeted immunotherapies (bispecific antibodies or Chimeric Antigen Receptor T cell therapies) in the management of metastatic castration resistant prostate cancer.

PATIENTS AND METHODS: We performed a retrospective analysis of the oral toxicities of PSMA-targeted immunotherapies of the patients seen at a single institution’s cancer center between 2020 and 2023. Descriptive statistics were used to summarize the data.

RESULTS: In a total of 19 patients treated with PSMA-targeted immunotherapies between 2020 and 2023, 9 patients (47%) experienced the following oral toxicities: xerostomia (n = 6; 32%), mucositis (n = 2; 10%), dysgeusia, dry throat and teeth sensitivity in (n = 1 each; 5%), respectively. Oral infections, such as candidiasis and herpes simplex, were not observed in any patients. Mucositis was managed with salt rinses and resolved within few months from onset. Xerostomia persisted in all the patients (median: 306 days, range: 98-484 days) among those who reported dry mouth at the time of data collection, despite treatment with salivary stimulants (n = 5; 83%). Dysgeusia was also persistent, although it was not specifically treated.

CONCLUSIONS: Patients treated with PSMA-targeted immunotherapies for prostate cancer can present with various short-term and long-term off-tumor on-target oral toxicities including xerostomia and dysgeusia that may affect quality of life. This study serves as a foundation to future prospective studies with a larger sample size and also helps oncologists managing prostate cancer patients with targeted immunotherapies to familiarize common oral toxicities. Furthermore, we emphasize the importance of oral medicine consultation for a comprehensive oral examination and management of oral complications.

ABSTRACT

INTRODUCTION: Controversy exists regarding potential increased toxic effects in patients with cosmetic implant-based augmentation (CIBA) who receive radiation therapy. We evaluated acute and chronic toxic effects associated with radiation therapy in women with prior CIBA treated with whole-breast irradiation (WBI) as part of breast conserving therapy (BCT) and compared these results against a cohort of patients without prior breast augmentation who received similar therapy.

METHODS: A retrospective review was performed to identify patients with a prior history of CIBA who subsequently underwent BCT with WBI. The control group consisted of consecutively treated patients without prior CIBA who also underwent BCT with WBI. Analyses included a comparison of baseline and treatment-associated factors between the augmentation and control groups, evaluation of toxic effects between both groups, and multivariable analysis of factors associated with the receipt of additional surgery following radiation.

RESULTS: Thirty-six patients with prior CIBA and 135 consecutively treated patients without CIBA were identified. Patients with prior CIBA were treated from 2006 through 2019, and patients without CIBA were treated from 2016 through 2019, though treatment characteristics and median follow-up time were similar between the two groups. Patients with prior CIBA were significantly less likely to experience acute moist desquamation (0% vs. 18%; P = .005). There were otherwise no statistically significant differences in acute (≤ 6 months) or chronic (> 6 months) toxic effects between the two groups. Rates of excellent/good chronic cosmetic outcome were 89% for the CIBA group and 97% in the control group (P = .094). On multivariable analysis, patients without prior CIBA (OR = 0.04; CI = 0.01-0.13; P < .001) and patients treated with moderately hypofractionated irradiation (OR = 0.08; CI = 0.02-0.23; P < .001) were significantly less likely to undergo additional surgery following receipt of WBI. Two patients experienced implant loss following radiation therapy.

CONCLUSIONS: WBI as part of BCT in patients with prior implant-based breast augmentation appears safe and is associated with favorable cosmetic outcomes. There was an increased need for additional surgery in patients with prior CIBA, but rates of acute and chronic toxic effects appeared similar to those in nonaugmented patients.

ABSTRACT

BACKGROUND: With the emergence of many novel therapies, the treatment decisions for multiple myeloma (MM) are increasingly guided by concerns of quality of life, achievement of cancer-free remission, living a longer overall survival, and a relentless search for a cure; however, the impact of various decision-making factors on patients’ actual therapy choices and the patients’ desire for cure and survival is mainly unknown. The lack of a valid and reliable measure for uncovering patients’ preferences for cure and survival makes it more challenging to put this factor into the actual treatment decision equation.

PURPOSE: This study examined the psychometric properties of the Values and Preferences Elicitation Questionnaire-Cure and Survival Preference Scale (VPEQ-CSPS) instrument.

METHODS: The VPEQ-CSPS instrument was deployed using an anonymous Qualtrics online survey to patients diagnosed with MM within the network of International Myeloma Foundation online patient support groups across the United States. One hundred seventy-four (N = 174) valid responses were obtained and used to examine the validity and reliability of the VPEQ-CSPS.

RESULTS: Exploratory factor analysis (EFA) revealed a Kaiser-Meyer-Olkin value of 0.72 indicating excellent sample adequacy. A statistically significant Bartlett’s test of sphericity (P < .001) indicated significant correlations among the variables of the dataset to conduct the EFA. The internal consistency coefficients indicated adequate reliability of the instrument with Cronbach’s alpha value at 0.80. The EFA and parallel analysis revealed the 5-item VPEQ-CSPS as a valid and reliable unidimensional scale that can be used by oncology clinicians to elicit their patient’s preferences for cure and survival. This new instrument has the potential to contribute to the achievement of shared decision-making for myeloma treatment decisions.
