AbstractDespite the clinical benefit associated with gilteritinib in relapsed/refractory acute myeloid leukemia (AML), most patients eventually develop resistance through unknown mechanisms. To delineate the mechanistic basis of resistance to gilteritinib, we performed targeted sequencing and scRNASeq on primary FLT3-ITD-mutated AML samples. Co-occurring mutations in RAS pathway genes were the most common genetic abnormalities, and unresponsiveness to gilteritinib was associated with increased expression of bone marrow-derived hematopoietic cytokines and chemokines. In particular, we found elevated expression of the TEK-family kinase, BMX, in gilteritinib-unresponsive patients pre- and post-treatment. BMX contributed to gilteritinib resistance in FLT3-mutant cell lines in a hypoxia-dependent manner by promoting pSTAT5 signaling, and these phenotypes could be reversed with pharmacological inhibition and genetic knockout. We also observed that inhibition of BMX in primary FLT3-mutated AML samples decreased chemokine secretion and enhanced the activity of gilteritinib. Collectively, these findings indicate a crucial role for microenvironment-mediated factors modulated by BMX in the escape from targeted therapy and have implications for the development of novel therapeutic interventions to restore sensitivity to gilteritinib.

BackgroundIdiopathic pleuroparenchymal fibroelastosis (iPPFE) is a rare interstitial lung disease characterised by predominant upper-lobe fibrosis involving the pleura and subpleural lung parenchyma. Despite its poor prognosis, there is no consensus on prognostic determinants of iPPFE to date. Because volume loss in the upper lobe is a distinct feature of iPPFE, we hypothesised that the lung volume of the bilateral upper lobes (upper-lobe volume) accurately indicates disease severity and mortality risk in iPPFE patients.MethodsThis retrospective study assessed two cohorts of 132 patients with iPPFE (69 in Hamamatsu cohort; 63 in Seirei cohort) and 45 controls. Each lobe volume was quantitatively measured using three-dimensional computed tomography at the time of iPPFE diagnosis and standardised using predicted forced vital capacity.ResultsThe standardised upper-lobe volume in iPPFE patients was less than half that of controls, whereas the lower-lobe volume did not decrease. iPPFE patients with lower standardised upper-lobe volume had significantly shorter survival rates than those with higher volume (median survival: 6.08versus2.48 years, p<0.001). In multivariate analysis, the lower standardised upper-lobe volume was significantly associated with increased mortality adjusting for age, sex and forced vital capacity (HR 0.939). A composite scoring model, including age, sex and standardised upper-lobe volume, better predicted risk of death than the gender-age-physiology model.ConclusionAssessment of upper-lobe volume provides useful information for managing iPPFE by evaluating disease severity and mortality risk in clinical practice.

Abstract
Purpose
A multidisciplinary approach is essential for trauma patients’ treatment, particularly for cases with open lower extremity fractures, which are considered major traumas requiring a comprehensive approach. Recently, the social demand for severe-trauma centers has increased. This study analyzed the clinical impact of establishing a trauma center for the treatment of open lower extremity fractures.

Methods
A retrospective chart review was conducted for trauma patients admitted to our hospital. Patients were classified into two groups: before (January 2014–December 2015, 178 patients) and after establishment of a Level-1 trauma center (January 2017–December 2018, 125 patients). We included patients with open fracture below the knee level and Gustilo type II/III, but excluded those with life-threatening trauma that affected the treatment choice.

Results
Total 273 patient were included in this study, initial infection was significantly more common and external fixator application significantly less in post-center establishment group. The time to emergency operation decreased significantly from 13.89 ± 17.48 to 11.65 ± 19.33 h post-center setup. By multivariate analysis, the decreased primary amputation and increased limb salvage was attributed to establishment of the trauma center.

Conclusion
With the establishment of the Level-1 trauma center, limbs of patients with open lower extremity fractures could be salvaged, and the need for primary amputation was decreased. Early control of initial open wound infection and minimizing external fixator use allowed early soft tissue reconstruction. The existence of the center ensured a shorter interval to emergency operation and facilitated interdepartmental cooperation, which promoted active limb salvage and contributed to patients’ quality of life.

Abstract
Background
Thyroid dysfunction has been reported in severe liver diseases. The aim of this study was to analyze the impact of serum thyroid-stimulation hormone (TSH) levels on the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF).

Methods
This retrospective cohort study included 1,862 patients with HBV-related ACLF. Risk factors associated with 30-day and 90-day survival, hazard ratios (HRs), and 95% confidence intervals (CIs) for TSH were estimated using Cox proportional hazards regression. The Area Under the ROC curve (AUROC) analysis was carried out, and the cut-off values were calculated. After grouping by the cut-off value, survival was compared between the groups using the log-rank test. This study data is from the “Survival Cohort Study (SCS)”, which has been registered at ClinicalTrials.gov (NCT03992898).

Results
Multivariate analysis indicated that an elevated TSH level was a highly significant predictor for 30-day survival (HR = 0.743, 95% CI: 0.629–0.878, P < 0.001) and 90-day survival (HR = 0.807, 95% CI: 0.717–0.909, P < 0.001). The AUROC of TSH level for 30-day and 90-day mortality were 0.655 and 0.620, respectively, with the same best cut-off values of 0.261 µIU/mL. Log-rank test showed that the group with higher TSH level had higher 30-day (78.5%, 95% CI: 76.1%-80.9% vs. 56.9%, 95% CI: 53.4%-60.4%; P < 0.001) and 90-day survival rate (61.5%, 95% CI: 58.6%-64.4% vs. 42.8%, 95% CI: 39.3%-46.3%; P < 0.001). Similar findings were observed in subgroups analysis. After adjusting for age and other risk factors, the higher level of TSH remained associated with 30-day survival (HR = 0.602, 95% CI: 0.502–0.721, P < 0.001) and 90-day survival (HR = 0.704, 95% CI, 0.609–0.814, P < 0.001).

Conclusions
Serum TSH level significantly correlate with HBV-related ACLF patients’ survival and may be of value for predicting 30-day and 90-day survival of patients with HBV-related ACLF.

Published: July 2022

Abstract
Background
Very few studies have compared the effects and side effects of vancomycin and teicoplanin in patients with methicillin-resistant Staphylococcus aureus pneumonia. This study aimed to compare the efficacy and safety of vancomycin and teicoplanin in patients with methicillin-resistant Staphylococcus aureus pneumonia.

Methods
This study examined 116 patients with methicillin-resistant Staphylococcus aureus pneumonia who met the inclusion criteria and were treated with either vancomycin (n = 54) or teicoplanin (n = 62). The primary (i.e., clinical failure during treatment) and secondary outcomes (i.e., mortality rates, discontinuation of study drugs due to treatment failure, side effects, and clinical cure) were evaluated.

Results
The vancomycin group presented lower clinical failure rates (25.9% vs. 61.3%, p < 0.001), discontinuation due to treatment failure (22.2% vs. 41.9%, p = 0.024), and mortality rates (3.7% vs 19.4%, p = 0.010). The Cox proportional hazard model revealed that teicoplanin was a significant clinical failure predictor compared with vancomycin (adjusted odds ratio, 2.198; 95% confidence interval 1.163–4.154). The rates of drug change due to side effects were higher in the vancomycin group than in the teicoplanin group (24.1% vs. 1.6%, p < 0.001).

Conclusions
Vancomycin presented favorable treatment outcomes and more side effects compared with teicoplanin, which suggests that clinicians would need to consider the efficacy and potential side effects of these drugs before prescription.

Abstract
Background
There is a four-fold risk for hepatitis B infection among healthcare workers compared to the general population. Due to limited access to diagnosis and treatment of hepatitis B in many resource-constrained settings, there is a real risk that only few healthcare workers with viral hepatitis may get screened or diagnosed and treated. Studies on hepatitis B vaccination among healthcare workers in developing countries are sparse and this bodes ill for intervention and support. The aim of the study was to estimate the prevalence and explored the associated factors that predicted the uptake of the required, full dosage of hepatitis B vaccination among healthcare workers (HCWs) in five developing countries using nationally representative data.

Methods
We used recent datasets from the Demographic and Health Surveys Program’s Service Provision Assessment Survey. Descriptive summary statistics and logistic regressions were used to produce the results. Statistical significance was pegged at p < 0.05.

Results
The proportion of HCWs who received the required doses of hepatitis B vaccine in Afghanistan, Haiti, Malawi, Nepal, and Senegal were 69.1%, 11.3%, 15.4%, 46.5%, and 17.6%, respectively. Gender, occupational qualification, and years of education were significant correlates of receiving the required doses of hepatitis B among HCWs.

Conclusions
Given the increased risk of hepatitis B infection among healthcare workers, policymakers in developing countries should intensify education campaigns among HCWs and, perhaps, must take it a step further by making hepatitis B vaccination compulsory and a key requirement for employment, especially among those workers who regularly encounter bodily fluids of patients.
Risk factors for mortality in kidney transplant recipients with COVID‐19: a single centre experience and case–control study

Published: July 2022

Abstract
Background
COVID-19 infection is considered to cause high mortality in kidney transplant recipients (KTR). Old age, comorbidities and acute kidney injury are known risk factors for increased mortality in KTR. Nevertheless, mortality rates have varied across different regions. Differences in age, comorbidities and varying standards of care across geographies may explain some variations. However, it is still unclear whether post-transplant duration, induction therapy, antirejection therapy and co-infections contribute to increased mortality in KTR with COVID-19. The present study assessed risk factors in a large cohort from India.

Methods
A matched case–control study was performed to analyze risk factors for death in KTR (N = 218) diagnosed with COVID-19 between April 2020 to July 2021 at the study centre. Cases were KTR who died (non-survivors, N = 30), whereas those who survived were taken as controls (survivors, N = 188).

Results
A high death-to-case ratio of 13.8% was observed amongst study group KTR infected with COVID-19. There was a high incidence (12.4%) of co-infections, with cytomegalovirus being the most common co-infection among non-survivors. Diarrhea, co-infection, high oxygen requirement, and need for mechanical ventilation were significantly associated with mortality on regression analyses. Antirejection therapy, lymphopenia and requirement for renal replacement therapy were associated with worse outcomes.

Conclusions
The mortality was much higher in KTR who required mechanical ventilation and had co-infections. Mortality did not vary with the type of transplant, post-transplant duration and usage of depletion induction therapy. An aggressive approach has to be taken for an early diagnosis and therapeutic intervention of associated infections.

Published: July 2022

AbstractBackgroundPage kidney (PK) is the occurrence of kidney hypoperfusion and ischemia due to pressure on the kidney by a subcapsular hematoma (SH), a mass, or fluid collection. SH after renal transplantation may result in kidney ischemia and graft loss.Case presentationWe present a rare case of early spontaneous SH in an allograft kidney that led to a decrease in renal function. A 56-year-old male patient underwent deceased donor kidney transplantation. After declamping, appropriate renal perfusion and immediate diuresis were observed, with no evidence of SH. However, his urinary output abruptly decreased 6 h postoperatively. Abdominal ultrasonography showed 28 mm deep SH on transplant and the resistive index (RI) increased to 0.98–1 and diastolic flow reversal was observed. Surgical interventions were performed 2 days after transplantation, following a further decrease in urinary output. Serum creatinine decreased to 2.2 mg/dL, urinary output increased to an average of 200 cc per hour and the RI value was decreased to 0.7 on POD 7.ConclusionIn patients with abrupt decreased renal function after transplantation, SH should be suspected and the presence of PK should be determined using Doppler USG. In these cases, surgical intervention may avoid allograft dysfunction.

AbstractBackgroundRecombinant human granulocyte colony-stimulating factor (rhG-CSF) reduces neutropenia events and is widely used in cancer patients receiving chemotherapy. However, the effects of rhG-CSF on distant organ metastasis (DOM) in non-small-cell lung cancer (NSCLC) patients following postoperative chemotherapy are not clear.MethodsA retrospective cohort study was performed on NSCLC patients who underwent complete surgical resection and postoperative systemic chemotherapy at The First Affiliated Hospital of Nanchang University between 1 January 2012 and 31 December 2017. The effect of rhG-CSF on DOM was assessed with other confounding factors using Cox regression analyses.ResultsWe identified 307 NSCLC patients who received postoperative systemic chemotherapy (n = 246 in the rhG-CSF group,n = 61 in the No rhG-CSF group). The incidence of DOM in postoperative NSCLC patients with rhG-CSF treatment was observably higher than in patients without rhG-CSF treatment (48.3% vs. 27.9%,p < 0.05). Univariate regression analysis revealed that rhG-CSF and pathological stage were independent risk factors for metastasis-free survival (MFS) (p < 0.05). RhG-CSF users had a higher risk of DOM (adjusted HR: 2.33, 95% CI: 1.31–4.15) than nonusers of rhG-CSF. The association between rhG-CSF and the risk of DOM was significant only in patients presenting with myelosuppression (HR: 3.34, 95% CI: 1.86–6.02) and not in patients without myelosuppression (HR: 0.71, 95% CI: 0.17–2.94, Interactionp-value< 0.01). The risk increased with higher dose density of rhG-CSF compared to rhG-CSF versus no users (pfor trend< 0.001).ConclusionThese analyses indicate that rhG-CSF use is related to DOM following postoperative chemotherapy in NSCLC.

Published: July 2022

Abstract
Background
Despite global interventions to prevent and control diarrhea, it still remains a public health problem leading to childhood morbidity and mortality majorly in developing countries. In Uganda, diarrhea is amongst the five leading causes of under-five mortality, contributing to more than 140,000 deaths every year and this accounts for 7.1% of all under-five mortalities in Uganda. Efforts to prevent and lower diarrheal diseases need to be informed by data on determinants of diarrhea. The study assessed factors associated with diarrheal diseases among children below five years in selected slum settlements in Entebbe municipality, Wakiso District, Uganda.

Methods
The study employed a cross-sectional study design covering 384 randomly selected households having children < 5 years old in the study area using quantitative research methods. Data was collected using close-ended questionnaires and diarrhea disease history was captured for the last month before the survey. Bivariate and multivariate logistic regression analyses were used to identify the risk factors associated with childhood diarrhea considering a 95% confidence level.

Results
The prevalence of Diarrhea disease in children among the selected slum settlements in Entebbe municipality was found to be at 62.4%. Access to water from a protected water source (deep well and borehole), presence of a vent in toilets, age, and child birth weight were found to be significantly associated with diarrheal diseases among children below five years in the selected slum settlements in Entebbe municipality.

Conclusion
The prevalence of childhood diarrhea among children < 5 years of age in selected slums of Entebbe municipality was found high. Use of water from a protected source, presence of a vent in toilets, age, child birth and weight were identified as predictors of diarrhea occurrence. These findings imply that community health education is urgently needed for fighting childhood diarrhea in the study area to eliminate the predisposing factors to diarrhea.

Abstract
Background
Early essential newborn care has been implemented in countries regardless high or low neonatal mortality. This study aims to investigate the current practice of skin-to-skin contact (SSC) and its effect on exclusive breastfeeding during the hospital stay.

Methods
This is a cross-sectional study of 1812 Vietnamese mothers in multicenter. A questionnaire answered by the mothers was used to assess the duration of both SSC and breastfeeding practices. Multivariable logistic regression was used to identify a dose–response relationship between early SSC and prevalence of exclusive breastfeeding in hospital.

Results
There were 88.7% of mothers experiencing SSC with their infants right after birth and the highest prevalence of SSC was found in district hospitals. Among those experiencing SSC, 18.8% of the infants received more than 90 min of SSC and completed the first breastfeeding during SSC time. Prevalence of exclusive breastfeeding during maternity hospital stay was 46.7%. We found a significant dose–response relation between the duration of SSC and exclusive breastfeeding in hospital. Compared with infants without SSC, the prevalence of exclusive breastfeeding was higher in infants who experienced SSC for 15–90 min (adjusted odds ratio [aOR], 95% confidence interval [95%-CI]: 2.62 [1.61–4.27]) and more than 90 min (aOR [95%-CI]: 5.98 [3.48–10.28]). Completed first breastfeeding during SSC time (aOR [95%-CI]: 4.24 [3.28–5.47]) and being born in district hospitals (aOR [95%-CI]: 2.35 [1.79–3.09]) were associated with increased prevalence of exclusive breastfeeding during hospital stay. On the other hand, mother education level as high school/intermediate (aOR [95%-CI]: 0.58 [0.42–0.82]) and place of residence classified as rural decreased odds of exclusive breastfeeding in hospital (aOR [95%-CI]: 0.78 [0.61–0.99]).

Conclusion
Our results demonstrate a strong dose–response relationship between duration of SSC and exclusive breastfeeding in hospital. Interventions that support exclusive breastfeeding during hospital stay, especially achieving prolonged uninterrupted SSC, could improve the duration of breastfeeding.
Multisystem inflammatory syndrome in a neonate with severe hemophilia - a diagnostic challenge in COVID times: a case report
Authors: Arun Sumitha , Cherian Taliya Grace , Philip Chepsy 
Published: July 2022

Abstract
Background
Multisystem Inflammatory Syndrome in Neonates (MIS-N) can occur following antenatal COVID- 19 infection in the mother. Here we report a rare case of a neonate with Hemophilia A and MIS-N.

Case presentation
A 2-day-old baby presented with an intramuscular hematoma, neonatal seizures, and isolated activated partial thromboplastin time (APTT) prolongation. The neurosonogram showed a subdural hematoma. A diagnosis of Hemophilia A was made and was confirmed by factor 8 assay and genetic analysis. Supportive measures and Factor 8 replacement was initiated. A rising trend of inflammatory markers and an ongoing need for mechanical ventilation were noted. As there was a history of COVID-19 in the mother in the third trimester, MIS-N was diagnosed. The baby was treated with intravenous immunoglobulin (IVIG) and steroids, and there was an improvement in the clinical and laboratory markers. However, the baby developed seizures on day 16. There was an increase in the subdural hemorrhage and a further rise in inflammatory markers. A craniostomy and hematoma evacuation was done and the baby improved.

Conclusion
The concurrent occurrence of hemophilia A with intracranial bleed, and MIS-N in a neonate is a diagnostic challenge. It is important to have a high index of suspicion to ensure timely diagnosis and treatment of MIS-N in this pandemic era.
