Inappropriate laboratory test utilization in outpatient tertiary care: Implications for value-based healthcare.

OBJECTIVES: To assess the rate of inappropriate repetition of laboratory testing and estimate the cost of such testing for thyroid stimulating hormone (TSH), total cholesterol, vitamin D, and vitamin B12 tests. METHODS: A retrospective cohort study was carried out in the Family Medicine and Polyclinic Department at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia. Clinical and laboratory data were collected between 2018-2021 for the 4 laboratory tests. The inappropriate repetition of tests was defined according to international guidelines and the costs were calculated using the hospital prices. RESULTS: A total of 109,929 laboratory tests carried out on 23,280 patients were included in this study. The percentage of inappropriate tests, as per the study criteria, was estimated to be 6.1% of all repeated tests. Additionally, the estimated total cost wasted amounted to 2,364,410 Saudi Riyals. Age exhibited a weak positive correlation with the total number of inappropriate tests (r=0.196, p=0.001). Furthermore, significant differences were observed in the medians of the total number of inappropriate tests among genders and nationalities (p<0.001). CONCLUSION: The study identified significantly high rates of inadequate repetitions of frequently requested laboratory tests. Urgent action is therefore crucial to overcoming such an issue.

Variations in Hospital Admissions of Non-Communicable Disease Patients Before and During The COVID-19 Pandemic (A Tertiary Care Setting, January 2018-June 2021).

BACKGROUND: This study aimed to analyze the variations (if any) in hospital admissions of patients with any of the five common non-communicable diseases (NCDs), based on secondary analysis of electronic health records of patients admitted to Hacettepe University Hospitals at least once, from January 1, 2018 through June 15, 2021. DESIGN: Data were recruited from hospital's electronic health records on patients with diagnoses of ischemic heart disease, hypertension, diabetes, cancer, and chronic obstructive pulmonary disease, using relevant ICD-10 codes. RESULTS: Compared to the corresponding time span in the pre-pandemic period, the number of hospital admissions of patients with selected five NCDs significantly decreased during the pandemic, with an official start in Turkey on March 11, 2020. Number of total-, out-patient-, and in-patient admissions of NCD patients were significantly lower in the pandemic period compared to the expected values in time series analysis, controlling for patient characteristics, and seasonality. CONCLUSIONS: Study findings suggest that there has been a prominent impediment in NCD patients' access to, and/or use of health care services over the pandemic, which might evolve to higher admission rates, severity and fatality of such patients in the upcoming years. Further studies are warranted for confirmation of our findings in other care settings, with individual-based data on care compensation through settings other than regular admission sites (if any), and/or the reasons for under-use of services.

Odontologia hospitalar: uma análise crítica sobre a inserção do cirurgião dentista na atenção terciária no estado do Rio Grande do Sul, Brasil / Hospital dentistry: a critical analysis of the role of the dental surgeon in tertiary care in the state of Rio Grande do Sul, Brazil

Objetivo: analisar a inserção do cirurgião dentista na atenção terciária no estado do Rio Grande do Sul, Brasil. Método: estudo descritivo ecológico, com uso de dados secundários registrados pelo Cadastro Nacional de Estabelecimentos de Saúde no ano de 2023. A coleta de dados foi realizada em duas etapas. Na primeira etapa também foram coletados os dados do CNES referentes à presença do cirurgião dentista, tipo de vínculo contratual e especialidades ofertadas pelos serviços. Já na segunda etapa os dados coletados foram referentes aos indicadores sociodemográficos dos profissionais com habilitação em odontologia hospitalar utilizando as informações disponibilizadas pelo Sistema WSCFO do Conselho Federal de Odontologia. A análise dos dados foi realizada com o suporte do software TabWin, versão 3.6, e do software estatístico R v. 4.2.3. Os dados foram analisados por meio de análise descritiva. Resultados: apenas 6,11% das instituições são certificadas e consideradas Hospitais de Ensino. A maioria dos estabelecimentos (87,14%) oferece atendimento pelo SUS. Quanto à presença de cirurgiões dentistas nos estabelecimentos, 64,63% dos estabelecimentos relataram tê-los, enquanto 35,37% não possuem esse profissional em sua equipe. Neste estudo, constatamos que uma correlação positiva do cirurgião dentista com o número de leitos de UTI adulto e ao maior porte do hospital. Conclusão: observa-se que ainda há necessidade de estruturação da atenção terciária no Estado do Rio Grande do Sul, no que se refere à odontologia hospitalar. Há poucos os cirurgiões dentistas com uma carga horária dedicada exclusivamente ao atendimento hospitalar clínico a beira leito.(AU)

Objective: To analyze the inclusion of dental surgeons in tertiary care in the state of Rio Grande do Sul, Brazil. Method: a descriptive ecological study using secondary data recorded by the National Register of Health Establishments in 2023. Data was collected in two stages. In the first stage, data was also collected from the CNES regarding the presence of a dental surgeon, the type of contractual relationship and the specialties offered by the services. In the second stage, data was collected on the sociodemographic indicators of professionals qualified in hospital dentistry using the information provided by the WSCFO System of the Federal Council of Dentistry. The data was analyzed using TabWin software, version 3.6, and R v. 4.2.3 statistical software. The data was analyzed using descriptive analysis. Results: only 6.11% of institutions are certified and considered Teaching Hospitals. The majority of establishments (87.14%) provide care through the SUS. As for the presence of dental surgeons in the establishments, 64.63% of the establishments reported having them, while 35.37% did not have this professional on their team. In this study, we found a positive correlation between the number of adult ICU beds and the size of the hospital. Conclusion: There is still a need to structure tertiary care in the state of Rio Grande do Sul, in terms of hospital dentistry. There are few dental surgeons with a workload dedicated exclusively to bedside clinical hospital care.(AU)

High SARS-CoV-2 Prevalence among Healthcare Workers in Cochabamba, Bolivia.

Healthcare workers (HCWs) are at increased risk of SARS-CoV-2 infection. The aim of the study was to estimate the SARS-CoV-2 seroprevalence among HCWs in Cochabamba, Bolivia and to determine the potential risk factors. In January 2021, a cross-sectional SARS-CoV-2 seroprevalence study was conducted in 783 volunteer clinical and non-clinical HCWs in tertiary care facilities. It was based on IgG detection using ELISA, chemiluminiscence, and seroneutralisation tests from dried blood spots. Analysis revealed a high seroprevalence (43.4%) of SARS-CoV-2 IgG antibodies. The combination of anosmia and ageusia (OR: 68.11; 95%-CI 24.83-186.80) was predictive of seropositivity. Belonging to the cleaning staff (OR: 1.94; 95%-CI 1.09-3.45), having more than two children in the same house (OR: 1.74; 95%-CI 1.12-2.71), and having been in contact with a close relative with COVID-19 (OR: 3.53; 95%-CI 2.24-5.58) were identified as risk factors for seropositivity in a multivariate analysis. A total of 47.5% of participants had received medication for COVID-19 treatment or prevention, and only ~50% of symptomatic subjects accessed PCR or antigenic testing. This study confirms a massive SARS-CoV-2 attack rate among HCWs in Cochabamba by the end of January 2021. The main risk factors identified are having a low-skilled job, living with children, and having been in contact with an infected relative in the household.

Diagnostic value of different interleukins and procalcitonin in critically ill patients admitted with suspected sepsis.

BACKGROUND: : Many biomarkers have now been studied such as C-reactive Protein (CRP), procalcitonin (PCT), etc., and are widely used for the diagnosis of sepsis in clinical practice which may determine the appropriate antibiotic treatment. A flowcytometric cytokine bead array (CBA) assay has now been used to determine multiple interleukins (IL), simultaneously. The aim of this study was to determine the cytokine (IL2, IL4, IL6, IL10, TNFα, INFγ, and IL17) profiles of interleukins in plasma of sepsis patients by using multiplex Flowcytometric CBA array assay. MATERIALS AND METHOD: s: A total of 99 consecutive patients admitted with the suspected sepsis were studied. PCT concentrations were measured by using the enzyme-linked fluorescent immunoassay (ELFA) technique and flow cytometry-based BD™ CBA Cytokine Kit was used to evaluate levels of 7 cytokines [IL-2, IL-4, IL-6, IL-10, Tumour Necrosis Factor (TNF), Interferon- γ (IFN-γ), and IL-17A]. RESULTS: Microbiologically defined infection (MDI) demonstrated a positive culture report in 79/99 (79.7%) of patients. The IL6 [1873.7 (4-5000)] and IL10 [(154.7 (0-1764)] levels were significantly higher in septic patients than those in the negative MDI IL6 [901 (4-5000)] and IL10 [110.4 (4-1372)] levels. The AUROC value of IL6 [0.66 (0.53-0.79)] was found to be the highest among all followed by IL10 [0.65 (0.51-0.79)], IFNγ [0.63 (0.51-0.77)], PCT [0.61 (0.48-0.75)], and TNFα [0.55 (0.42-0.69)]. CONCLUSION: Our study suggests that that IL6 is substantially more economical and can reduce the investigation cost to half as compared with the procalcitonin assay.

The Impact of the COVID-19 Pandemic on the Workload, Case Mix and hospital Resources at a Tertiary Vascular Unit.

BACKGROUND: The aim of this study was to examine the COVID-19 pandemic and its associated impact on the provision of vascular services, and the pattern of presentation and practice in a tertiary referral vascular unit. METHODS: This is a retrospective observational study from a prospectively maintained data-base comparing two time frames, Period 1(15th March-30th May 2019-P1) and Period 2(15th March-30th May 2020-P2)All the patients who presented for a vascular review in the 2 timeframes were included. Metrics of service and patient care episodes were collected and compared including, the number of emergency referrals, patient encounters, consultations, emergency admissions and interventions. Impact on key hospital resources such as critical care and imaging facilities during the two time periods were also examined. RESULTS: There was an absolute reduction of 44% in the number of patients who required urgent or emergency treatment from P1 to P2 (141 vs 79). We noted a non-significant trend towards an increase in the proportion of patients presenting with Chronic Limb Threatening Ischaemia (CLTI) Rutherford 5&6 (P=0.09) as well as a reduction in the proportion of admissions related to Aortic Aneurysm (P=0.21). There was a significant absolute reduction of 77% in all vascular interventions from P1 to P2 with the greatest reductions noted in Carotid (P=0.02), Deep Venous (P=0.003) and Aortic interventions (P=0.016). The number of lower limb interventions also decreased though there was a significant increase as a relative proportion of all vascular interventions in P2 (P=0.001). There was an absolute reduction in the number of scans performed for vascular pathology; Duplex scans reduced by 86%(P<0.002), CT scans by 68%(P<0.003) and MRIs by 74%(P<0.009). CONCLUSION: We report a decrease in urgent and emergency vascular presentations, admissions and interventions. The reduction in patients presenting with lower limb pathology was not as significant as other vascular conditions, resulting in a significant rise in interventions for CLTI and DFI as a proportion of all vascular interventions. These observations will help guide the provision of vascular services during future pandemics.

Emergency general surgery transfer to lower acuity facility: The role of right-sizing care in emergency general surgery regionalization.

BACKGROUND: Regionalization of emergency general surgery (EGS) has primarily focused on expediting care of high acuity patients through interfacility transfers. In contrast, triaging low-risk patients to a nondesignated trauma facility has not been evaluated. This study evaluates a 16-month experience of a five-surgeon team triaging EGS patients at a tertiary care, Level I trauma center (TC) to an affiliated community hospital 1.3 miles away. METHODS: All EGS patients who presented to the Level I TC emergency department from January 2020 to April 2021 were analyzed. Patients were screened by EGS surgeons covering both facilities for transfer appropriateness including hemodynamics, resource need, and comorbidities. Patients were retrospectively evaluated for disposition, diagnosis, comorbidities, length of stay, surgical intervention, and 30-day mortality and readmission. RESULTS: Of 987 patients reviewed, 31.5% were transferred to the affiliated community hospital, 16.1% were discharged home from the emergency department, and 52.4% were admitted to the Level I TC. Common diagnoses were biliary disease (16.8%), bowel obstruction (15.7%), and appendicitis (14.3%). Compared with Level I TC admissions, Charlson Comorbidity Index was lower (1.89 vs. 4.45, p < 0.001) and length of stay was shorter (2.23 days vs. 5.49 days, p < 0.001) for transfers. Transfers had a higher rate of surgery (67.5% vs. 50.1%, p < 0.001) and lower readmission and mortality (8.4% vs. 15.3%, p = 0.004; 0.6% vs. 5.0%, p < 0.001). Reasons not to transfer were emergency evaluation, comorbidity burden, operating room availability, and established care. No transfers required transfer back to higher care (under-triage). Bed days saved at the Level I TC were 693 (591 inpatients). Total operating room minutes saved were 24,008 (16,919, between 7:00 am and 5:00 pm). CONCLUSION: Transfer of appropriate patients maintains high quality care and outcomes, while improving operating room and bed capacity and resource utilization at a tertiary care, Level I TC. Emergency general surgery regionalization should consider triage of both high-risk and low-risk patients. LEVEL OF EVIDENCE: Prospective comparative cohort study, Level II.

The clinical significance of staphylococcus pettenkoferi: a retrospective review at a tertiary care medical center.

Staphylococcus pettenkoferi is a recently described coagulase-negative staphylococcal pathogen. We retrospectively reviewed 25 cases in which S. pettenkoferi was identified in routine cultures (12 blood, 13 other). Most were found with commensal flora and considered clinically insignificant, but its significance was uncertain in two cases from non-healing, deep foot wounds.

The Demographics of Patients Presenting for Laryngological Care at an Academic Medical Center.

OBJECTIVES/HYPOTHESIS: Few studies address the demographics/epidemiology/socioeconomic status of patients presenting to a laryngologist at a tertiary care center for treatment. To identify any possible disparities in voice, airway, and swallowing care, we sought to analyze the aforementioned data for new patients presenting to the voice center at an academic medical center. METHODS: This is a retrospective cohort study of prospectively collected data from an institutional database of 4,623 new adult patients presenting for laryngological care at a tertiary care, academic medical center from 2015 to 2020. Demographic data were analyzed. RESULTS: Of 4,623 patients, 62.8% were female and 37.2% were male with ages ranging from 19 to 99 years (Avg 59.51, standard deviation 15.83). Patients were 81.8% white, 13% black, and 5.2% other, compared with 56.3% white, 34.8% black, 20% other in the local municipality from US Census Data. Payer mix included 46.98% Medicare, 42.59% commercial insurance, 3.22% Medicaid, 5.19% other, and 2.01% uninsured/self-insured. Patient demographics based on primary diagnosis codes were also examined. A majority of patients presented with voice-related complaints. CONCLUSIONS: Understanding the demographics of those with laryngological disorders will help to develop targeted interventions and effective outreach programs for underrepresented patient populations. Future multicenter studies could provide further insight into the distribution of healthcare disparities in laryngology. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:626-632, 2022.

Outcomes among children and adults at risk of severe dengue in Sri Lanka: Opportunity for outpatient case management in countries with high disease burden.

BACKGROUND: Healthcare systems in dengue-endemic countries are often overburdened due to the high number of patients hospitalized according to dengue management guidelines. We systematically evaluated clinical outcomes in a large cohort of patients hospitalized with acute dengue to support triaging of patients to ambulatory versus inpatient management in the future. METHODS/PRINCIPAL FINDINGS: From June 2017- December 2018, we conducted surveillance among children and adults with fever within the prior 7 days who were hospitalized at the largest tertiary-care (1,800 bed) hospital in the Southern Province, Sri Lanka. Patients who developed platelet count ≤100,000/µL (threshold for hospital admission in Sri Lanka) and who met at least two clinical criteria consistent with dengue were eligible for enrollment. We confirmed acute dengue by testing sera collected at enrollment for dengue NS1 antigen or IgM antibodies. We defined primary outcomes as per the 1997 and 2009 World Health Organization (WHO) classification criteria: dengue hemorrhagic fever (DHF; WHO 1997), dengue shock syndrome (DSS; WHO 1997), and severe dengue (WHO 2009). Overall, 1064 patients were confirmed as having acute dengue: 318 (17.4%) by NS1 rapid antigen testing and 746 (40.7%) by IgM antibody testing. Of these 1064 patients, 994 (93.4%) were adults ≥18 years and 704 (66.2%) were male. The majority (56, 80%) of children and more than half of adults (544, 54.7%) developed DHF during hospitalization, while 6 (8.6%) children and 22 (2.2%) adults developed DSS. Overall, 10 (14.3%) children and 113 (11.4%) adults developed severe dengue. A total of 2 (0.2%) patients died during hospitalization. CONCLUSIONS: One-half of patients hospitalized with acute dengue progressed to develop DHF and a very small number developed DSS or severe dengue. Developing an algorithm for triaging patients to ambulatory versus inpatient management should be the future goal to optimize utilization of healthcare resources in dengue-endemic countries.

Effect of the COVID-19 Pandemic Preparation and Response on Essential Health Services in Primary and Tertiary Healthcare Settings of Amhara Region, Ethiopia.

Countries like Ethiopia have had to make difficult decisions to balance between the demands of the COVID-19 pandemic and maintaining the essential health service delivery. We assessed the effect of preventive COVID-19 measures on essential healthcare services in selected health facilities of Ethiopia. In a comparative cross-sectional study, we analyzed and compared data from seven health facilities over two periods: the pre-COVID-19 period before the first reported COVID-19 case in the country and during the COVID-19 period. Data were summarized using descriptive statistics and the independent t test. During the COVID-19 period the average number of monthly patient visits in the emergency department, pediatrics outpatient, and adult outpatient dropped by 27%, 30%, and 27%, respectively compared with the pre-COVID-19 period. Family planning; institutional delivery; childhood immunization; antenatal care-, hypertension- and diabetic patient follow-up, did not vary significantly between pre-COVID-19 and during COVID-19. Moreover, the monthly average number of tuberculosis (TB) and HIV patients who visited health facilities for drug refill and clinical evaluation did not vary significantly during the two periods. In conclusion, the study highlights that the effect of public restrictions to mitigate the COVID-19 pandemic on essential care systems should be considered.

One-Year Outcomes after Ledipasvir/Sofosbuvir Treatment of Chronic Hepatitis C in Teenagers with and without Significant Liver Fibrosis-A Case Series Report.

One-year outcomes after therapy with ledipasvir/sofosbuvir (LDV/SOF) in children with chronic hepatitis C (CHC) presenting with and without significant liver fibrosis were analyzed. We included patients aged 12-17 years treated with LDV/SOF, presenting with significant fibrosis (F ≥ 2 on the METAVIR scale) in transient elastography (TE) at the baseline and we compared the outcomes with that of patients without fibrosis. Patients were followed every 4 weeks during the treatment, at the end of the therapy, at week 12 posttreatment, and one year after the end of treatment. Liver fibrosis was established using noninvasive methods: TE, aspartate transaminase-to-platelet ratio index (APRI), and Fibrosis-4 index (FIB-4). There were four patients with significant fibrosis at baseline: one with a fibrosis score of F2 on the METAVIR scale, and three with cirrhosis (F4) at baseline. One year after the end of treatment, the hepatitis C viral load was undetectable in three of them. One patient was lost to follow-up after week 4. In two out of the four patients, a significant improvement and regression of liver fibrosis was observed (from stage F4 and F2 to F0-F1 on the METAVIR scale). In one patient, the liver stiffness measurement median increased 12 weeks after the end of the treatment and then decreased, but still correlated with stage F4. An improvement in the APRI was observed in all patients. In four patients without fibrosis, the treatment was effective and no progression of fibrosis was observed. A one-year observation of teenagers with CHC and significant fibrosis treated with LDV/SOF revealed that regression of liver fibrosis is possible, but not certain. Further observations in larger groups of patients are necessary to find predictors of liver fibrosis regression.

The Limitations of Cytomegalovirus DNA Detection in Cerebrospinal Fluid of Newborn Infants With Congenital CMV Infection: A Tertiary Care Neonatal Center Experience.

BACKGROUND: Congenital cytomegalovirus (cCMV) infection of the central nervous system (CNS) can cause ventriculomegaly, gliosis, calcifications and cortical defects. Detection of CMV DNA in cerebrospinal fluid by PCR (CSF-CMV-PCR) is a marker of CNS involvement. OBJECTIVE: To evaluate a diagnostic value of the positive CSF-CMV-PCR in cCMV. METHODS: Analysis of clinical, laboratory, neuroimaging and single-nucleotide polymorphisms (SNPs) data according to the results of CSF-CMV-PCR were performed in infants with cCMV. RESULTS: A total of 168 infants were included; 145 (86.3%) had negative and 23 (13.7%) had positive CSF-CMV-PCR results. Associations between the positive CSF-CMV-PCR results and prematurity (odds ratio [OR] = 3.24; 95% confidence interval [CI]: 1.30-8.07), microcephaly (OR = 5.67; 95% CI: 2.08-15.41), seizures (OR = 4.15; 95% CI: 1.10-15.67), sensorineural hearing loss (OR = 6.6; 95% CI: 2.49-17.46), splenomegaly (OR = 8.13; 95% CI: 3.12-21.16), hepatitis (OR = 10.51; 95% CI: 3.31-33.35), petechiae (OR = 10.21; 95% CI: 3.78-27.57) and heterozygous T/C genotype at TLR4rs4986791 (OR = 7.88; 95% CI: 1.55-40.12) were observed. When using a multivariate logistic regression analysis, only the presence of severe sensorineural hearing loss (OR = 7.18; 95% CI: 1.75-29.34, P = 0.006), cystic lesions on MRI (OR 5.29; 95% CI: 1.31-21.36, P = 0.02), and calcifications on MRI (OR = 7.19; 95% CI: 1.67-30.97, P = 0.008) remained as the significant independent predictors of the positive CSF-CMV-PCR results. CONCLUSIONS: The detection of CMV DNA in CSF is associated with a higher rate of CNS damage including abnormal MRI neuroimaging and severe hearing loss. Therefore, detection of CMV DNA in CSF may be considered as a marker of severe CNS injury in cCMV infection. However, the very low prevalence of the positive CSF-CMV-PCR results, even in infants with proven CNS involvement, may imply its limited role in clinical practice.

Absence of Case of Mucormycosis (March 2020-May 2021) under strict protocol driven management care in a COVID-19 specific tertiary care intensive care unit.

AIMS: With a sudden increase in cases of mucormycosis seen in Covid -19 patients, we conducted a retrospective analysis of all admitted patients in a tertiary care covid-19 hospital looking at incidence of mucormycosis. METHODS: Intensive care unit daily rounds data stored in an electronic format was retrieved by one of the consultants, looking for incidence of mucormycosis, diabetes mellitus, adherence to protocol for steroid use, glycemic control and use of monoclonal antibodies. Also, patients follow up data base of post covid Outpatients Department was searched for cases of mucormycosis. RESULTS: A total of 5248 patients were admitted between March 2020 to May 2021, of which 1027 were in ICU and 4221 in wards. Of the 1027 patients admitted in Intensive care unit, 915 received steroids and 417 had diabetes as existing co-morbidity. No case of mucormycosis was reported during the stay in the hospital and during immediate outpatient department follow up. The low dose steroids were administered as per state government protocol for treating COVID 19, a nurse driven strict glycemic control regime (blood glucose level was maintained between 140 and 180 mg/dl through the admission in ICU and was achieved consistently in 842 (82%) patients, followed along with minimal use of other immunomodulatory like monoclonal antibodies. CONCLUSION: A strict adherence to protocol of low dose steroids coupled with strict glycemic control helped in eliminating the risk and incidence of mucormycosis in a tertiary care dedicated covid-19 hospital.

Coping with COVID: Developing a Rapid-cycle Frontline Quality-improvement Process to Support Employee Well-being and Drive Institutional Responsiveness in a Tertiary Care Faith-based Hospital in Rural Kenya.

The coronavirus disease 2019 (COVID-19) pandemic has demanded rapid institutional responses to meet the needs of patients and employees in the face of a serious new disease. To support the well-being of frontline staff, a series of debriefing sessions was used to drive a rapid-cycle quality-improvement process. The goals were to confidentially determine personal coping strategies used by staff, provide an opportunity for staff cross-learning, identify what staff needed most, and provide a real-time feedback loop for decision-makers to create rapid changes to support staff safety and coping. Data were collected via sticky notes on flip charts to protect confidentiality. Management reviewed the data daily. Institutional responses to problems identified during debrief sessions were tracked, visualized, addressed, and shared with staff. More than 10% of staff participated over a 2-week period. Feedback influenced institutional decisions to improve staff schedules, transportation, and COVID-19 training.

Diagnosis and management of acute appendicitis in 21 pediatric hematology and oncology patients at a tertiary care cancer center.

Acute appendicitis is a rare gastrointestinal complication of anti-cancer chemotherapy and hematopoietic stem cell transplantation. Among a cohort of 2341 hemato-oncologic patients at a pediatric tertiary care cancer center, we identified 21 patients (0.9%) with 23 episodes of acute appendicitis, based on pathological imaging of the appendix and clinical findings. Median age at diagnosis was 10.21 years. Types of underlying disease included acute leukemias (n = 15), solid tumors (n = 4), and aplastic anemia (n = 2). Clinical symptoms seen in > 1 case were recorded for all 23 episodes as follows: abdominal pain, n = 22; abdominal tenderness, n = 4; fever, n = 7; nausea, n = 2; emesis; n = 2; diarrhea, n = 5; and constipation, n = 2. Median leukocyte count at diagnosis was 0.5 × 109/L, with a median of 0.1 × 109/L for the absolute neutrophil count (ANC). All patients received broad-spectrum antibiotics and 18/23 (78%) patients underwent uneventful appendectomy after a median of 5 days and with a median ANC of 0.7 × 109/L. Median duration until continuation of chemotherapy was 17 days for the 20 cases of appendicitis occurring during the patients' disease course. Overall, 5/21 (19%) patients died including one related to the appendicitis itself which progressed to a typhlitis and was due to a fungal infection. The other fatalities were transplant- (n = 2) and leukemia-related (n = 2). Acute appendicitis is a rare and usually not life-threatening event in pediatric hemato-oncologic patients, which, if managed by prompt administration of broad-spectrum antibiotics (and antimycotics), can be safely followed by an elective (delayed) appendectomy, even before complete recovery of the neutrophils is achieved.

Assessment of the Implementation of Pharmacogenomic Testing in a Pediatric Tertiary Care Setting.

Importance: Pharmacogenomic (PGx) testing provides preemptive pharmacotherapeutic guidance regarding the lack of therapeutic benefit or adverse drug reactions of PGx targeted drugs. Pharmacogenomic information is of particular value among children with complex medical conditions who receive multiple medications and are at higher risk of developing adverse drug reactions. Objectives: To assess the implementation outcomes of a PGx testing program comprising both a point-of-care model that examined targeted drugs and a preemptive model informed by whole-genome sequencing that evaluated a broad range of drugs for potential therapy among children in a pediatric tertiary care setting. Design, Setting, and Participants: This cohort study was conducted at The Hospital for Sick Children in Toronto, Ontario, from January 2017 to September 2020. Pharmacogenomic analyses were performed among 172 children who were categorized into 2 groups: a point-of-care cohort and a preemptive cohort. The point-of-care cohort comprised 57 patients referred to the consultation clinic for planned therapy with PGx targeted drugs and/or for adverse drug reactions, including lack of therapeutic benefit, after the receipt of current or past medications. The preemptive cohort comprised 115 patients who received exploratory whole-genome sequencing-guided PGx testing for their heart conditions from the cardiac genome clinic at the Ted Rogers Centre for Heart Research. Exposures: Patients received PGx analysis of whole-genome sequencing data and/or multiplex genotyping of 6 pharmacogenes (CYP2C19, CYP2C9, CYP2D6, CYP3A5, VKORC1, and TPMT) that have established PGx clinical guidelines. Main Outcomes and Measures: The number of patients for whom PGx test results warranted deviation from standard dosing regimens. Results: A total of 172 children (mean [SD] age, 8.5 [5.6] years; 108 boys [62.8%]) were enrolled in the study. In the point-of-care cohort, a median of 2 target genes (range, 1-5 genes) were investigated per individual, with CYP2C19 being the most frequently examined; genotypes in 21 of 57 children (36.8%) were incompatible with standard treatment regimens. As expected from population allelic frequencies, among the 115 children in the whole-genome sequencing-guided preemptive cohort, 92 children (80.0%) were recommended to receive nonstandard treatment regimens for potential drug therapies based on their 6-gene pharmacogenetic profile. Conclusions and Relevance: In this cohort study, among both the point-of-care and preemptive cohorts, the multiplex PGx testing program provided dosing recommendations that deviated from standard regimens at an overall rate that was similar to the population frequencies of relevant variants.

Treatment Outcome of Children with Retinoblastoma in a Tertiary Care Referral Hospital in Indonesia.

Background: Although survival rates for retinoblastoma (RB) are over 95% in high-income countries, its high mortality rate in low and middle-income countries remains a great concern. Few studies investigated treatment outcome and factors contributing to RB survival in these latter settings. Aims of this study are to determine treatment outcome of Indonesian children diagnosed with RB and to explore factors predictive of treatment outcome. Methods: This study was a retrospective medical records review combined with an illustrative case report. Children newly diagnosed with RB between January 2011 and December 2016 at a tertiary care referral hospital in Indonesia were included. A home visit was conducted to perform an in-depth interview with a mother of two children affected by RB. Results: Of all 61 children with RB, 39% abandoned treatment, 21% died, 20% had progressive or relapsed disease and 20% event-free survival. Progressive or relapsed disease was more common in older (≥ 2 years at diagnosis, 29%) than young (<2 years at diagnosis, 0%) children (P=0.012). Event-free survival estimate at 5 years was higher in young (42%) than older (6%) children (P=0.045). Odds-ratio for event-free survival was 6.9 (95% CI: 1.747 ­ 27.328, P=0.006) for young versus older children. Other clinical and socio-demographic characteristics had no significant correlation with treatment outcome or event-free survival. The case report elucidated conditions and obstacles that Indonesian families face when their children are diagnosed with RB. Conclusion: Survival of children with RB in Indonesia is much lower compared to high-income and many other low and middle-income countries. Abandonment of treatment is the most common cause of treatment failure. Older age at diagnosis is associated with more progressive or relapsed disease and worse survival. Interventions to improve general public and health-care providers' awareness, early detection and treatment adherence are required.

Metabolic syndrome and its related biochemical derangements in breast cancer patients who received neoadjuvant chemotherapy: A study from a tertiary care oncology centre from Puducherry, South India.

BACKGROUND AND AIMS: Comparison of the existence of metabolic syndrome, its components and their related biochemical complications between newly diagnosed and treated breast cancer patients. METHODS: Forty newly diagnosed untreated breast cancer patients and forty breast cancer patients who had received 7 cycles of neoadjuvant chemotherapy were recruited as group 1 and group 2 respectively. Height, weight, blood pressure, hormonal status, and tumor size were noted. The fasting blood glucose and lipid profile were estimated in AU 5811 Beckman coulter Clinical chemistry analyzer. Fasting insulin was estimated using Beckman Coulter access immunoassay system (UnicelDxI600). HbA1c assay was carried out in HPLC based ion exchange chromatography (Tosoh automated glycohemoglobin analyzer G8. Homeostasis Model Assessment 2-IR (HOMA 2-IR), HOMA-% B and HOMA-% S were calculated using an online calculator HOMA CALCULATOR [Oxford University]. Serum hsCRP and MDA were estimated by ELISA. FRAP assay was carried out manually to measure antioxidant status. RESULTS: The existence of metabolic syndrome as well as type 2 diabetes was higher in the treated group when compared to the untreated patients. However, there were no significant differences in the indices of glucose homeostasis, low grade inflammation, oxidative stress and individual components of metabolic syndrome between the two groups. The triple negative patients were more prone to develop metabolic syndrome when compared to the triple positive patients. CONCLUSION: Suitable therapeutic approaches may be planned out to address the metabolic syndrome and its related complications among breast cancer patients especially during the course of treatment.

SARS-CoV-2 seroprevalence in healthcare workers in a tertiary healthcare network in Victoria, Australia.

BACKGROUND: Healthcare workers (HCW) are exposed to an increased risk of COVID-19 through direct contact with patients and patient environments. We calculated the; seroprevalence of SARS-CoV-2 in HCW at Eastern Health, a tertiary healthcare network in Victoria, and assessed associations with demographics, work location and role. METHODS: A cross-sectional cohort study of HCW at Eastern Health was conducted. Serum was analysed for the presence of antibodies to SARS-CoV-2, and all participants completed; an online survey collecting information on demographics, place of work, role, and exposures; to COVID-19. Seroprevalence was calculated as the proportion participants with SARS-CoV-2; antibodies out of all tested individuals. RESULTS: The crude seroprevalence of SARS-CoV-2 antibodies in this study was 2.17% (16/736). Thirteen of the 16 (81.2%) positive cases had previously been diagnosed with COVID-19 by PCR: the seroprevalence in the group not previously diagnosed with COVID by PCR was 0.42% (3/720). Having direct contact with COVID-19 patients did not increase the likelihood of having positive serology. A prior history of symptoms consistent with COVID-19 was associated with a higher likelihood of having positive serology (OR 17.2, p = 0.006, 95%CI: 2.25-131.55). CONCLUSION: Our calculated seroprevalence of 2.17% is higher than estimated in the general Australian population, but lower than that reported in HCW internationally. The; majority of those with positive serology in our study had previously been diagnosed with COVID-19 by PCR based testing. Seropositivity was not associated with interaction with COVID-19 positive patients, highlighting effective infection prevention and control practices within the workplace.
