Bacterial Contamination of Donor Blood Units in a Ghanaian Blood Bank: A Critical Concern for Transfusion Safety

Abstract Introduction/Objective Background: Blood transfusions, while life-saving, pose a significant risk to patient safety, with transfusion-associated bacterial sepsis emerging as a persistent and potentially fatal threat. The prevalence and severity of bacterial contamination in donor blood units necessitate regular surveillance to ensure safe and effective transfusion therapy. Aim This study aimed to identify and assess the susceptibility of bacterial isolates in whole blood donor units at the blood bank of Cape Coast Teaching Hospital in the Central Region of Ghana. Methods/Case Report Method(s): One hundred and three (103) units of stored whole blood units, declared safe for transfusion (testing negative for HIV I&II, HBsAg, HCV, and syphilis), were inoculated into Brain Heart Infusion Broth and incubated for 24 hours. The inoculated broths were then cultured on MacConkey agar (MAC), Chocolate agar (CHOC), and Blood agar. Gram-negative and Gram-positive isolates were identified using standard biochemical tests. Antimicrobial susceptibility testing was performed using the disc diffusion method. Results (if a Case Study enter NA) Results: Of the 103 donor blood units tested, 33 (32.03%) were found to have bacterial isolates. Gram-positive organisms accounted for 67.14% of the isolates, including Coagulase negative Staphylococcus, Bacillus spp, and S. aureus. Gram-negative bacteria constituted 32.86% of the isolates, with Citrobacter freundii, Serratia marcescens, E. coli, and Providencia stuartii identified. Notably, 62.9% of the bacterial isolates were skin commensals, while 25.7% were of enteric origin and 11.4% were of nosocomial origin. Resistance to commonly used antibiotics varied among isolates, with Coagulase-negative Staphylococcus exhibiting resistance to amoxicillin (92.86%) and erythromycin (76.19%), while Citrobacter freundii showed resistance to levofloxacin (75.00%) and ofloxacin (75.00%). Conclusion Conclusion(s): The high incidence of bacterial contamination in donor blood units highlights the need for improved phlebotomy procedures and decontamination practices at blood banks in Ghana to reduce the risk of sepsis in transfusion recipients. Furthermore, this study provides valuable information regarding antibiotic resistance patterns in bacterial isolates, emphasizing the importance of antibiotic stewardship in Ghana. In conclusion, this study underscores the urgency of addressing bacterial contamination in donor blood units in Ghanaian blood banks to enhance transfusion safety.

Study of placenta histopathology in low birth weight deliveries: A prospective cross-sectional study at Nobel Medical College Teaching Hospital

Background: Placenta is the most important organ that represents the status of the mother and fetus. Its examination on gross and microscopy can reveal varied pregnancy-related diseases, decreasing future adverse pregnancy outcomes. This study aims to examine the placenta histopathologically among low birth weight pregnancies. Materials and methods: A prospective case-control study was conducted in the Department of Pathology over one year. The placenta of low birth weight (weight < 2.5 kg) term pregnancies were histopathologically examined. The maternal demographics, co-morbidity, gravida, and hemoglobin levels were recorded. Descriptive statistics, and student t-test or Chi-square test were used for two-group analysis. Results: Thirty-two consecutive patients enrolled in each group. A significant proportion of the patients in the study group were anemic (9.2 vs. 11.5 gm/dl; p=0.03). Pregnancy-induced hypertension rate was significantly higher in the study group (31% vs. 9%; p = 0.042). Gross observations in low birth weight pregnancies were sub-chorionic fibrin deposition (75%), calcification (37%) and infarction (31%). On microscopy, chorionic vessel thrombosis was significantly higher in the study group (56% vs. 6%; p= 0.003). Furthermore, chorioamnionitis (34%) and placental floor infarction (12%) were also observed in a significantly higher number of placentas in the study group. Conclusions: Anemia and pregnancy-induced hypertension are important associated factors for low birth weight pregnancies. Pathological examinations reveal higher fibrin deposition, infarction, calcification, sub-chronic vessel thrombosis, and chorioamnionitis in low birth weight placenta.

Coordination in Dynamic Teams: Investigating a Learning–Productivity Trade-Off

The rapid growth in the use of teams and multiple team membership has led more organizations to structure work around dynamic teams, characterized by short lifespans and fluid membership boundaries. This approach to organizing work makes it difficult for teams to work efficiently or to support the learning and growth of members. Given the importance of productivity and learning, we ask how these processes can be supported in dynamic teams. We do so in a randomized controlled field experiment conducted with 91 teams in a teaching hospital, a context in which physician trainees must learn while providing patient care in dynamic teams of care providers. We randomly assigned physician teams, or “core” teams, to launch their work with an intervention focused either on internal coordination among the core team members or on external coordination with a changing cast of external contributors such as nurses and specialists. We measured resulting levels of internal and external coordination over teams’ week-long lifespans and observed that external coordination was associated with improved team efficiency, whereas internal coordination was associated with improved individual learning. Post hoc exploratory analysis suggested that individual learning was highest when teams achieved high levels of both internal and external coordination, and it was positively correlated with improvement in the team’s patients’ average length of hospital stay. We discuss the implications of the demonstrated causal effects of team launches, along with our exploratory findings, for the management of dynamic teams and the opportunities to mitigate potential trade-offs between learning and productivity.

Influence of Interpretation on Patient-Healthcare Provider Communication and Management of Chronic Conditions in Kenya: A Case of JOOTRH Hospital Kisumu

The Ministry of Health in Kenya projects that deaths from chronic conditions will increase by 65% by 2030. To efficiently manage chronic illnesses, effective communication between patients and healthcare providers is of crucial importance. However, studies have shown that many patients lack knowledge about their conditions and the treatment processes. This study investigated the experiences of patients and caregivers while communicating with healthcare-providers on management of chronic conditions. The study was undertaken at the Jaramogi Oginga Odinga Teaching and Referral Hospital (JOOTRH) in Kisumu County, Kenya. It adopted the relativist-interpretivist paradigm and qualitative approach to generate and analyze data. Purposive and snowball sampling techniques were used to identify 10 patients and 5 caregivers who were drawn from patient support groups at the hospital. 10 healthcare providers were sampled. Data was generated through in-depth interviews and focus group discussions which were transcribed and analyzed using a thematic approach. Study findings indicate that healthcare providers were knowledgeable and believed that patients needed to be given relevant information. English was the main language used by health providers, which often created a language barrier among patients and caregivers who did not understand the language. This created opportunities for misinformation when interpreters were used. The hospital lacked trained interpreters, hence caregivers and hospital staff acted as interpreters. This was found to affect patients’ privacy and disclosure, especially where the patient did not want their health information to be accessed by a third party. Patients felt the information they received to be inadequate.

Comparison between early and late weight bearing after anterior cruciate ligament reconstruction surgery.

The anterior cruciate ligament (ACL) is a strip of dense connective tissue that runs from the femur to the tibia with a relatively poor blood supply. It prevents the femoral condyles from rolling posteriorly. ACL is commonly injured in any knee trauma, ranging from a little sprain to a total rupture. The arthroscope is the gold standard approach for identifying ACL tears, which may be treated conservatively or surgically. To assess the efficiency of immediate and delayed weight bearing after arthroscopic ACL reconstruction. Cohort longitudinal study carried through 6years from 2017 to 2023 et al.-kindy Teaching, Ulamaa, and Almuktar hospitals 186 patients, the patients were divided randomly into 2 groups, group A (n = 93) with immediate (after 10days) weight bearing and group B (n = 93) with delayed (after 1month) weight bearing following ACL reconstruction. any patients with chondral lesions, aged less than 19 or more than 40years, knee osteoarthritis, ligament damage, and deformity in lower extremities were excluded. Patients from both groups A and B had complete ACL tears and underwent arthroscopic ACL reconstruction follow-up for 6months duration regarding stiffness, infection, giving up pain, swelling, and quadriceps muscle atrophy. In group A, there were 93 patients,70 male and 23 female, and meniscal injury was 89 patients. While in group B (93 patients) 57 male and 36 female, meniscal injury in group B was 91. There is a statistically significant difference regarding knee swelling. (80.6% in group A, and 10.8% in group B), and knee pain in which (79.6% in group A patients and only 7.5% in group B). There is no significant value between the two groups about the knee getting given up, infection, stiffness, and quadriceps muscle atrophy. Delay weight bearing after ACL reconstruction makes the patients less prone to knee pain and effusion but more prone to quadriceps muscle atrophy.

Posterior uveal biopsy and the trans-scleral Essen forceps biopsy technique.

Differentiating neoplastic and non-neoplastic uveal tumours can present a diagnostic challenge; intra-ocular biopsy may be necessary. The novel trans-scleral Essen Forceps biopsy (TSEB) technique can improve diagnostic yield compared to fine needle aspiration biopsy (FNAB). We present a case demonstrating the technique and its added value. We also review the success rate of TSEB performed at two tertiary eye centres. Retrospective case report and consecutive case series from August 2021 to March 2023. Inclusion criteria were patients who underwent TSEB of posterior uveal lesions from Moorfields Eye Hospital and Sheffield Teaching Hospitals in the United Kingdom. The outcomes were biopsy success rate and complication rate RESULTS: Eleven biopsies met the inclusion criteria. Eight (73%) were successful, which comprised six uveal melanomas, one melanocytoma and one extranodal marginal zone (ENMZ) lymphoma. One TSEB did not yield tissue for histological examination because of perioperative sample handling. Two (18%) biopsies were histologically inconclusive; both were treated as uveal melanoma on clinical grounds or repeat biopsy. The only complication was vitreous loss and retinal hole without retinal detachment in one eye with a very posterior, shallow choroidal lesion. TSEB is an effective alternative to established biopsy techniques, yielding larger tissue samples than FNAB with intact tissue architecture. We recommend adding TSEB to the armamentarium of the ocular oncologist.

Chromobacterium violaceum: An incidental finding in a neonate.

Chromobacterium violaceum is a gram-negative saprophytic bacterium causing human infection in tropical and subtropical countries. Such infections are uncommon but cause high mortality when the bacterium enters the bloodstream through an open wound. We present a case of C. violaceum infection isolated from a blood culture sample in a neonate identified at a tertiary care teaching hospital in North East Uttar Pradesh. Timely diagnosis by microbiological methods and antimicrobial treatment led to a successful cure for this life-threatening infection. Thus, such bacteria should be included in the routine spectrum for differential diagnosis of sepsis, to provide a chance of cure.

Association between patient-reported frailty and nonhome discharge among older patients with acute stroke: A prospective study.

To investigate the association between prestroke frailty and nonhome discharge, prolonged length of stay as well as functional outcomes. Prospective observational study. Single urban teaching hospital in Guangzhou, China. Consecutive sample of 271 older patients admitted with acute stroke. N/A. A five-item FRAIL scale (0∼5 points) and the stroke severity at onset were measured. The primary outcome of interest was nonhome discharge, with secondary outcomes including prolonged length of stay and worse short-term prognosis. Multivariable logistic regression adjusting for confounding factors was used to determine the association between patient-reported frailty and nonhome discharge, prolonged length of stay, worse short-term prognosis. The population had a median age of 68 [interquartile range (IQR), 64∼74)]years, with 50 individuals (18.5%) identified as frail. After adjusting for age, sex, Barthel index, National Institutes of Health Stroke Scale, and Mini-Mental Status Exam score at admission, patients with self-reported frailty were significantly likely to experience nonhome discharge (Odds Ratio [OR] = 4.788; 95% confidence interval [CI] = 1.272∼18.017; p = .021), prolonged length of stay (OR = 4.76; 95% CI = 1.80∼12.56; p = .002), mRS scores at 30 days (OR = 6.72;95% CI = 1.79∼25.20; p = .005) and three months postdischarge and three-month (OR = 8.94; 95% CI = 2.10∼38.08; p = .003). In older adults with stroke, frailty is associated with nonhome discharge, prolonged length of stay, and worse short-term prognosis, regardless of the stroke severity, cognition, and Barthel index score at admission. FRAIL scale can be used as a practical screening tool in acute care setting by multidisciplinary team in supporting discharge process.

Tuberculosis-related deaths at a tertiary hospital in Zambia: Insights into the prevalence and associated factors.

Tuberculosis (TB) mortality remains a significant public health concern globally. This study aimed to determine the prevalence of tuberculosis-related deaths and associated factors among patients at Livingstone University Teaching Hospital (LUTH) Chest Clinic, Zambia. We conducted a retrospective cross-sectional study among 694 individuals (507 adult and 187 children) diagnosed with drug susceptible TB disease between January 1, 2021, and December 31, 2022. Demographic and clinical information were collected from medical records using a data collection form. Multivariable logistic regression was used to determine factors associated with TB-related death. Statistical significance was set at p < 0.05. STATA version 15 was used for all data analysis. The prevalence of TB-related death among adults (above 19 years old) was 18.4% (n = 93) whereas that in children (below 19 years old) was 7.0% (n = 187). Living with HIV (AOR 1.75, 95% CI 1.00-3.08, p = 0.049) was positively associated with TB-related death among the adult patients while being on a family based direct observation therapy (DOT) plan was negatively associated with TB-related death both among adults and among children, (AOR 0.24, 95% CI 0.13-0.45, p <0.001) and (AOR 0.2, 95% CI 0.03-0.99, p = 0.039) respectively. This study found a high TB-related mortality rate, both among adults and children, exceeding the national target of 5% and it was significantly associated with HIV status and DOT plan. There is therefore a need to enhance strategies aimed at reducing TB-related deaths, especially among those living with HIV.

The safety and efficacy of miniaturized percutaneous nephrolithotomy in children.

To assess the use of miniaturized percutaneous nephrolithotomy (mini-PCNL) for renal stones in children, as well as its safety and efficacy. Seventy-seven patients with more than 15mm renal stones whose age was less than 15 years were enrolled in this prospective case-controlled study at Al-Ramadi Teaching Hospital, Ar Razi Private Hospital, and Ghazi Al-Hariri Hospital for Surgical Specialties,Anbar and Baghdad, Iraq. The study was conducted from January 2020 to January 2024. The group mentioned above served as group A, and it was compared to the control group (group B), which consisted of 70 adult patients aged 18-60 years. Patients in both groups underwent mini-PCNL. Gender, stone size and location, time of operation, stone-free rate, hemoglobin drop, need for blood transfusion, postoperative fever, associated visceral injury, and need for further interventions such as extracorporeal shock wave lithotripsy or flexible ureteroscopy (ESWL or FURS) were compared in both groups. The age of patients in group A ranged from 8 months to 15 years with a mean (4.30 ± 3.16), while in group B ranged from 18 to 60 years with a mean (36.3 ± 12.0), p-value 0.001. There were no statistically significant differences regarding gender distribution, stone size, and location, p-value > 0.05. The stone-free rate was 87.01% for group A and 88.57% for group B, with no statistical difference, p-value 0.773. Hemoglobin drop was 1.096 ± 0.412 for group A and 1.195 ± 0.110 for group B, p-value 0.046. Blood transfusion was needed in one case in each group with no statistical difference, p-value 0.946. The need for ESWL was 3 cases in group A, and 2 cases in group B, with no statistical difference between the two groups, p-value 0.729. The need for FURS was 4 cases in group A and 3 cases in group B, p-value 0.796. Operative time was 30 to 125min in group A and 34 to 129min in group B, p-value 0.941. Postoperative fever was seen in 23 cases in group A and 21 cases in group B, p-value 0.986. Minor liver injury was seen was seen in one case in each group. The use of mini-PCNL for treating renal stones in children is safe and effective as it is associated with a relatively low rate of significant complications and achieves a high stone-free rate.

Pulmonary Embolism Management Audit and Machine Learning Analysis of Delayed Anticoagulation in a Swiss Teaching Hospital.

Background/Objectives: Diagnosing acute pulmonary embolism (PE) is challenging due to its wide range of symptoms and numerous differential diagnoses. Medical professionals must balance performing all essential examinations and avoiding unnecessary testing. This study aimed to retrospectively audit the diagnosis and treatment of acute PE at a Swiss public teaching hospital to determine the adherence to current guidelines and to identify the factors associated with the delayed initiation of anticoagulation in PE patients. Methods: In this retrospective observational cohort study, we included all adult patients hospitalized with PE at the Cantonal Hospital Baselland (KSBL) between November 2018 and October 2020, where the diagnosis was made within the first twelve hours of their arrival to the emergency department (ED). LASSO regression was employed to identify clinical characteristics associated with delayed anticoagulation initiation. Results: A total of 197 patients were included (mean age: 70 years, 54% female). The audit revealed that diagnostic workup was conducted according to guidelines in 57% of cases. Often, D-dimer levels were measured although not strictly necessary (70%). Pretest probability was assessed and documented using the Wells or Geneva score in only 3% of patients, and risk assessment via the Pulmonary Embolism Severity Index (PESI) score was documented in 21% of patients. The median time from ED arrival to CT scan was 120 min (IQR 89.5-210.5), and the median time to anticoagulation initiation was 193 min (IQR 145-277). Factors identified by LASSO associated with delayed anticoagulation included prolonged time from ED arrival to CT scan, the presence of distended jugular veins on examination, ED arrival in the morning, and presenting symptoms of weakness or tiredness. Complementary leg ultrasound was performed in 57% of patients, with 38% of these cases lacking prior clinical examination for deep vein thrombosis. The duration of the anticoagulation treatment was not specified in the discharge report for 17% of patients. A medical follow-up after discharge was recommended in 75% of the patients. Conclusions: In conclusion, while the management of PE at the KSBL generally adheres to high standards, there are areas for improvement, particularly in the morning performance, the use of a pretest probability assessment, D-dimer measurement, risk assessment via the PESI score, the performance of complementary leg ultrasounds, clarification of the anticoagulation duration, and follow-up management.

Eighteen-year trends in the rates of intra-operative cardiac arrest and associated mortality at a public university hospital in Brazil.

Intra-operative cardiac arrest is a rare but life-threatening event. Over the past two decades, various initiatives have improved the care of patients undergoing surgery at our quaternary teaching hospital in Brazil. We aimed to evaluate the epidemiology of intra-operative cardiac arrest and associated 30-day mortality over an 18-year period. A secondary aim was to identify associated risk factors. We conducted a retrospective observational study using data collected from 1 January 2005 to 31 December 2022. Factors associated with cardiac arrest and mortality were identified using multivariable logistic regression analysis. Among the 154,178 cases, the overall rates of intra-operative cardiac arrest (n = 297) and associated 30-day mortality (n = 248) were 19.3 (95%CI (16.6-21.9)) and 16.1 (95% CI 13.9-18.3) per 10,000 anaesthetics, respectively. These decreased over time (2005-2010 vs. 2017-2022) from 26.3 (95%CI 21.0-31.6) to 15.4 (95%CI 12.0-18.7) per 10,000 anaesthetics, and from 23.4 (95%CI 18.8-28.1) to 13.7 (95%CI 10.8-16.7) per 10,000 anaesthetics, respectively. Factors associated with intra-operative cardiac arrest included children aged < 1 year (adjusted OR (95%CI) 3.51 (1.87-6.57)); ASA physical status 3-5 (adjusted OR (95%CI) 13.85 (8.86-21.65)); emergency surgery (adjusted OR (95%CI) 10.06 (7.85-12.89)); general anaesthesia (adjusted OR (95%CI) 8.79 (4.60-19.64)); surgical procedure involving multiple specialities (adjusted OR (95%CI) 9.13 (4.24-19.64)); cardiac surgery (adjusted OR (95%CI) 7.69 (5.05-11.71)); vascular surgery (adjusted OR (95%CI) 6.21 (4.05-9.51)); and gastrointestinal surgery (adjusted OR (95%CI) 2.98 (1.91-4.65)). We have shown an important reduction in intra-operative cardiac arrest and associated 30-day mortality over an 18-year period. Identification of relative risk factors associated with intra-operative cardiac arrest can be used to improve the safety and quality of patient care, especially in a resource-limited setting.

Traumatic and Non-traumatic Radiculomedullary Compressions: A Comparative Analysis.

Background Radiculomedullary lesions represent a significant public health issue, with their epidemiological, clinical, and therapeutic characteristics varying depending on whether they are of traumatic or non-traumatic origin. The aim of this study was to compare clinical, therapeutic, and postoperative aspects between traumatic radiculomedullary lesions (TRML) and non-traumatic radiculomedullary lesions (NTRML). Methods This was a prospective cohort study conducted from 2020 to 2023 involving patients suffering from radiculomedullary lesions operated at the Department of Neurosurgery, University Teaching Hospital of Kinshasa. In addition to socio-demographic characteristics, the two patient groups - traumatic and non-traumatic - were compared based on clinical, therapeutic, and postoperative aspects using the American Spinal Injury Association (ASIA)and Spinal Cord Independence Measures (SCIM III) scores. Results We included 153 patients, with 73 traumatic cases (47.7%) and 80 non-traumatic cases (52.3%). TRMLs were predominantly caused by road traffic accidents (34%) and falls (11%), while NTRMLs were mainly due to disc herniations (22.2%) and tuberculosis (13.7%). The mean age for TRMLs was 35.4 ±12.8 years with a sex ratio of 3.5, compared to 50.7±15.9 years and a sex ratio of 1.1 for NTRMLs. TRMLs were more frequently located in the cervical region (32.8%) and the thoracolumbar junction (40%), whereas NTRMLs predominantly affected the thoracic (22.5%) and lumbar (63.7%) regions. Patients with NTRMLs had more incomplete lesions (98.7%) and better SCIM III scores at admission compared to TRMLs (p ˂ 0.001). TRMLs had more complete deficits 42 (57.3%) vs 1 (1.3%). Both groups significantly improved their ASIA and SCIM III scores postoperatively (p ˂ 0.001) but in a similar manner (Diff-in-diff: ASIA, p=0.955; SCIM, p=0.967). TRMLs developed more complications than NTRMLs (p˂0,001). Only five patients (11.6%) with ASIA A progressed to higher grades, and all remained dependent (SCIM III score ˂50). The average hospital stay was 89.2 ±74.2 days for TRMLs and 57.5±52.9 days for NTRMLs (p˂0.001). Conclusion This study revealed that TRMLs frequently affect young male individuals and are often located in the cervical region and thoracolumbar junction. In contrast, NTRMLs affect older individuals without gender preference and are usually found in the thoracic and lumbar regions. TRMLs often lead to complete deficits, pressure sores, urinary infections, and longer hospital stays compared to NTRMLs. Both patient groups showed significant postoperative improvement with no significant difference between them. However, patients with complete deficits showed less improvement in both groups.

Adequate Completion of Radiology Request Forms: A Clinical Audit at Managil Teaching Hospital in Sudan

Introduction: Clinical auditing is one method for improving the quality of patient care, including the completion of a request form. Radiology request forms are critical tools for communicating between the referring clinician and the radiologist/radiographer. Objectives: To evaluate the radiology request form and improve the request form content and design at Managil Teaching Hospital, Sudan. Methods: A two-cycle clinical audit methodology at radiology department - Managil Teaching Hospital. A total of 100 request forms were collected, with 50 forms acquired for each cycle. These forms were then compared to the standard structured form provided by the Royal College of Radiologists (RCR). In a second cycle, a pre-made request form was used. The data were inputted into Microsoft Excel 2016 and subsequently analysed. The obtained results were then compared to the RCR Standard. Results: A notable enhancement was noted in various aspects, such as the inclusion of the patient's age in the request forms. In the first cycle, the age was only recorded in 13% of the forms, however in the second cycle, it was recorded in 92% of the forms. Conclusion: A significant proportion of radiology request forms are incomplete but after the 2nd cycle of the audit there was massive improvement regarding adequate filling of the radiology request forms. which will aid in effectively diagnosing patients.

Antibiotic Resistance Pattern of Pathogens Isolated from Pediatric Patients during and after the COVID-19 Pandemic.

Background/Objectives: The present study aims to highlight the possible significant changes due to the COVID-19 pandemic in the resistance of pathogens involved in cases of pediatric infections. Methods: This study included children hospitalized in the Pediatric Intensive Care Unit, Surgery and Pediatrics from a tertiary teaching hospital, during and after the COVID-19 period (2020-2023). Results: The research included 845 samples collected during 2020-2023, from 685 pediatric patients. A total of 937 bacterial isolates were obtained, of which 509 isolates (54.32%) were Gram-negative bacteria. Around 30% of all the pathogens were multidrug-resistant (MDR), with a statistically significant increase post-pandemic, in the case of the MDR Escherichia coli strains (p < 0.05). A very high percentage of MDR Acinetobacter spp. isolates was found, with an important, but not statistically significant, increase in the post-pandemic period. The highest percentage of the MDR Gram-positive pathogens was registered in the case of S. aureus strains (31.80%). Over 20% of the Coagulase-negative Staphylococci (CoNS) strains isolated between 2020 and 2023 were MDR, with an important increase in the post-COVID-19 period. The proportion of carbapenem-resistant Gram-negative pathogens significantly decreased in the post-COVID-19 period compared with the COVID-19 period (p < 0.05), especially in the case of the Klebsiella spp. strains. Conclusions: Our findings revealed the increase in the post-COVID-19 period of the prevalence of MDR strains of Acinetobacter spp., CoNS, and Escherichia coli isolated in pediatric patient samples and a significant decline in the trend of the carbapenem-resistant Gram-negative pathogens, which may be due to the testing rate and to the specific pathology of the pediatric patients hospitalized in the two periods.

Attitudes, knowledge, and related factors on paediatric dental radiography among parents of children aged less than 13 years attended a tertiary care public dental hospital.

Dental radiography is an essential diagnostic tool in paediatric dentistry. To explore attitudes, knowledge, and related factors of paediatric dental radiography among parents who attended the radiology department of a premier public dental hospital. The study was conducted at the National Dental Hospital (Teaching) Sri Lanka among 124 parents whose children (<13-years) underwent dental radiographic examination. Data on sociodemographic characteristics, radiographic investigations, and parental knowledge and attitudes on paediatric dental radiography were collected using an interviewer-administered questionnaire. Data were entered and analyzed using the SPSS-21 statistical software package. The mean score (95% CI) of parental attitudes and knowledge on paediatric dental radiography were 17.55 (17.64-18.45) on a scale from 7 to 35 and 3.73 (3.34-4.13) on a scale from -7 to +7, respectively. Significant differences in parental knowledge were evident by child's age (p = 0.046), ethnicity (p = 0.035), and parental attitudes (p = 0.024). Binary logistic regression analysis revealed a significant independent association between parental attitudes with parental knowledge: OR (95% CI) = 2.413 (1.098-5.302) (p = 0.028). Parents demonstrated less favorable attitudes but sufficient knowledge on many aspects of paediatric dental radiography. Therefore, interventions are needed to improve parental attitudes on paediatric dental radiography especially by providing child-friendly services.

Skin injury: Associations with variables related to perfusion and pressure.

Skin injuries are a major healthcare problem that are not well understood or prevented in the critically ill, suggesting that underappreciated variables are contributing. This pilot study tested the hypothesis that perfusion-related factors contribute to skin injuries diagnosed as hospital-acquired pressure injuries (HAPIs). A total of 533 adult patients were followed over 2574 critical care days (mean age 62.4, standard deviation (SD) 14.3 years, mean body mass index 30.4 (SD 7.4) kg/m2, 36.4% female). This was a secondary analysis of prospective, non-randomised clinical data from an intensive care unit at a large urban teaching hospital. Factors related to perfusion, specifically two or more infusions of vasopressors/inotropes, temporary mechanical circulatory support (MCS), extracorporeal membrane oxygenation, and durable MCS, were analysed to determine whether they were more strongly associated with HAPIs than immobility due to prolonged mechanical ventilation (>72 h) or operating room time (>6 h). Patients diagnosed with a HAPI had a statistically significant higher risk of being exposed to variables related to perfusion and immobility (P < 0.05 for each variable). Perfusion-related variables, except durable MCS, had a larger effect on skin breakdown (number needed to harm (NNH) 4-10) than immobility-associated variables (NNH 12-17). The finding that perfusion-related variables predicted HAPIs may warrant consideration of alternative diagnoses, such as skin failure due to impaired perfusion as a pathophysiological process that occurs concurrently with multisystem organ failure. Differentiation of skin injuries primarily from circulatory malfunction, rather than external pressure, may guide the development of more effective treatment and prevention protocols. This pilot study suggests that the contribution of perfusion to skin injuries should be explored further.

Characterizing the Patterns of Cervical Cancer Symptom Recognition, Symptom Response, and Associated Factors Among Patients Treated in a Teaching Hospital in Ghana.

Cervical cancer is a major global health issue and ranks as the second leading cause of cancer-related deaths among women in Ghana. This study aimed to explore and characterize the patterns of symptom recognition associated with cervical cancer and the symptom responses among women in Ghana. A descriptive qualitative design utilizing 20 individual semistructured interview sessions was used. The study was conducted in one of Ghana's major cancer treatment centers. Data were collected using face-to-face interviews. The data were analyzed using NVivo 12 and presented as themes and subthemes. Data analysis revealed 2 main themes: barriers to symptom recognition and response and facilitators of early symptom recognition and symptom response. Barriers included deficient knowledge about cervical symptoms, spiritual attributions of symptoms, preference for herbal remedies for symptoms, misdiagnosis, and seeking help through multiple facility visits. Facilitating factors of symptom response include perceived severity/identification of additional symptoms, quick referrals with some navigation within the healthcare system, and advice from women's microcommunity. The study emphasizes the need for continuous educational efforts on cervical cancer and its symptoms. Healthcare providers, patients, and the public have a part to play in the awareness and early detection of cervical cancer. Initiatives that educate women about the early symptoms of cervical cancer and the importance of screening can help with early recognition. Educating communities about cervical cancer empowers individuals to take charge of their health and encourages supportive environments for women to seek care.
