Acute kidney injury: the experience of a tertiary center of Pediatric Nephrology / Insuficiência renal aguda: experiência de um centro terciário de Nefrologia Pediátrica

ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5-15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25-75) urinary protein-to-creatinine ratio 0.30 (0.27-0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25-75) GFR 75 (62-83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.

RESUMO Introdução: Insuficiência renal aguda (IRA) é uma deterioração abrupta da função renal. A incidência de IRA pediátrica está aumentando em todo o mundo, em ambientes críticos e não críticos. Nosso objetivo foi caracterizar apresentação, etiologia, evolução e desfechos da IRA em pacientes pediátricos internados em um centro de atendimento terciário. Métodos: Realizamos estudo retrospectivo observacional de centro único de pacientes com idade entre 29 dias a 17 anos e 365 dias internados em nossa Unidade de Nefrologia Pediátrica, de janeiro de 2012 a dezembro de 2021, com diagnóstico de IRA. A gravidade da IRA foi categorizada de acordo com os critérios do Kidney Disease Improving Global Outcomes (KDIGO). Os desfechos considerados foram óbito ou sequelas (proteinúria, hipertensão ou alterações na função renal em avaliações de acompanhamento de 3 a 6 meses). Resultados: Incluímos 46 pacientes com idade mediana de 13,0 (3,5-15,5) anos. Cerca de metade (n = 24; 52,2%) apresentou um fator de risco identificável para o desenvolvimento de IRA. Treze pacientes (28,3%) eram anúricos; todos foram classificados como IRA KDIGO 3 (p < 0,001). Quase um quarto (n = 10; 21,7%) dos pacientes necessitaram de terapia renal substitutiva. Aproximadamente 60% (n = 26) apresentou pelo menos uma sequela, sendo proteinúria a mais comum (n = 15; 38,5%; mediana (P25-75) da relação proteína/creatinina urinária 0,30 (0,27-0,44) mg/mg), seguida de taxa de filtração glomerular (TFG) reduzida (n = 11; 27,5%; mediana (P25-75) da TFG 75 (62-83) mL/min/1,73 m2). Conclusões: A IRA pediátrica está associada à morbidade substancial, com potencial para desenvolvimento de proteinúria e comprometimento da função renal e impacto relevante no prognóstico de longo prazo.

Bone aluminum accumulation in the current era / Acúmulo de alumínio no tecido ósseo na era atual

In the last few years, evidence from the Brazilian Registry of Bone Biopsy (REBRABO) has pointed out a high incidence of aluminum (Al) accumulation in the bones of patients with CKD under dialysis. This surprising finding does not appear to be merely a passive metal accumulation, as prospective data from REBRABO suggest that the presence of Al in bone may be independently associated with major adverse cardiovascular events. This information contrasts with the perception of epidemiologic control of this condition around the world. In this opinion paper, we discussed why the diagnosis of Al accumulation in bone is not reported in other parts of the world. We also discuss a range of possibilities to understand why bone Al accumulation still occurs, not as a classical syndrome with systemic signs of intoxication, as occurred it has in the past.

Nos últimos anos, evidências do Registro Brasileiro de Biópsia óssea (REBRABO) apontaram uma alta incidência de intoxicação por alumínio (Al) no tecido ósseo de pacientes com DRC em diálise. Essa surpreendente informação parece representar não apenas um acúmulo passivo deste metal, visto que dados prospectivos do REBRABO sugerem que a presença de Al no tecido ósseo pode estar independentemente relacionada a eventos cardiovasculares adversos maiores. Essas informações contrastam com a percepção mundial do controle epidemiológico dessa condição. Neste artigo de opinião, discutimos por que o diagnóstico de acúmulo ósseo de Al não é relatado em outras partes do mundo, e também discutimos uma gama de possibilidades para entender por que nós acreditamos que o acúmulo de Al no tecido ósseo ainda ocorre, não como se apresentava no passado, ou seja, como uma síndrome com sinais e sintomas sistêmicos de intoxicação.

Pregnancy Outcomes Among Teenagers at a National Referral Hospital in Uganda.

Introduction: Teenage pregnancy is a global public health challenge, and it is a major contributor to the high maternal and neonatal morbidity and mortality rates reported in sub-Saharan Africa and Uganda. However, there is a paucity of data regarding pregnancy outcomes and their associated factors among teenagers in Uganda. The purpose of this study was to determine the prevalence and factors associated with pregnancy outcomes among teenagers who delivered at a National Referral Hospital in Kampala, Uganda. Materials and Methods: This cross-sectional study was conducted among teenage mothers who delivered at a National Referral Hospital in Kampala, Uganda. Consecutive participant recruitment was done for those who fulfilled the eligibility criteria. The outcomes of interest included adverse maternal outcome with obstructed labor being used as a proxy and adverse fetal outcomes with birth asphyxia used as a proxy. Logistic regression analysis was used to determine the association between independent and dependent variables with a 5% level of statistical significance (α = 0.05). Results: Teenage pregnancy was associated with adverse maternal outcomes which included obstructed labor (18%) and preterm labor (5.5%). There were no maternal deaths during the study period. Adverse fetal outcomes observed in this study population included low birth weight (83%), birth asphyxia (18%), and stillbirth (4%). The only factor associated with adverse maternal outcome was gestational age where teenage mothers had 4 times likelihood of delivering before 37 weeks. Relatedly, teenage mothers had an 81% chance of having a preterm birth. Conclusion: Teenage pregnancy was generally not associated with adverse maternal or fetal outcomes except for preterm birth. The reasons for adverse pregnancy outcomes may reflect a combination of gynecological and biological immaturity, as well as adverse socioeconomic pressures.

Disease-specific health-related quality of life trajectories up to 15 years after curative treatment for esophageal cancer-a prospective cohort study.

BACKGROUND: The presence of distinct long-term disease-specific HRQL trajectories after curative treatment for esophageal cancer and factors associated with such trajectories are unclear. MATERIALS AND METHODS: This population-based and longitudinal cohort study included 425 esophageal cancer patients who underwent curative treatment, including esophagectomy, in Sweden in 2001-2005 and were followed up until 2020, that is, 15-year follow-up. The outcomes were 10 disease-specific HRQL symptoms, measured by the well-validated EORTC QLQ-OES18 questionnaire at 6 months (n = 402 patients), and 3 (n = 178), 5 (n = 141), 10 (n = 92), and 15 years (n = 52) after treatment. HRQL symptoms were examined for distinct trajectories by growth mixture models. Weighted logistic regression models provided odds ratios (OR) with 95% confidence intervals (95% CI) for nine factors in relation to HRQL trajectories: age, sex, education, proxy baseline HRQL, comorbidity, tumor histology, chemo(radio)therapy, pathological tumor stage, and postoperative complications. RESULTS: Distinct HRQL trajectories were identified for each of the 10 disease-specific symptoms. HRQL trajectories with more symptoms tended to persist or alleviate over time, while trajectories with fewer symptoms were more stable. Eating difficulty had three trajectories: persistently less, persistently moderate, and persistently more symptoms. The OR of having a persistently more eating difficulty trajectory was decreased for adenocarcinoma histology (OR = 0.44, 95% CI 0.21-0.95), and increased for pathological tumor stage III-IV (OR = 2.19, 95% CI 0.99-4.82) and 30-day postoperative complications (OR = 2.54, 95% CI 1.26-5.12). CONCLUSION: Distinct trajectories with long-term persistent or deteriorating disease-specific HRQL symptoms were identified after esophageal cancer treatment. Tumor histology, tumor stage, and postoperative complications may facilitate detection of high-risk patients for unwanted trajectories.

Associations of overweight/obesity with patient-reported outcome measures after oblique lumbar interbody fusion.

Background: Oblique lateral interbody fusion (OLIF) combined with transpedicular screw fixation has been practiced for degenerative spinal diseases of elderly patients for years. However, overweight patients have been shown to have longer operative times and more complications from surgery. The effect on clinical outcome is still uncertified. The objective of this study was to determine is overweight a risk factor to clinical outcome of OLIF combined with transpedicular screw fixation technique. Material and methods: A retrospective study in patients submitted to OLIF combined with transpedicular screw fixation from January 2018 to August 2019 was conducted. VAS score, ODI score and EQ5D were measured before the operation and one year after the operation. Results: A total of 111 patients were included with 48 patients in the non-obese group and 55 patients in the overweight/obese group. There was no significant difference between the two groups in gender, age, smoking history, hypertension, chronic kidney disease and diabetes mellitus. Overweight/obese group has higher BMI (28.4 vs. 22.7, p < 0.001) than non-obese group. There was no difference between the two groups in pre-operative VAS score, ODI score and EQ5D score. However, the healthy weight group improved much more than the overweight score in VAS score, ODI score and EQ5D score. Conclusion: The overweight/obese patient group had clinical outcomes worse than the non-obese group in terms of pain relief and life functions.

Impact of Latency Variations on the Predictive Value of Facial Nerve Proximal-to-Distal Amplitude Ratio during Vestibular Schwannoma Surgery.

Introduction This study highlights the relation between compound muscle action potential (CMAP) latency variations and the predictive value of facial nerve (FN) proximal-to-distal (P/D) amplitude ratio measured at the end of vestibular schwannoma resection. Methods Forty-eight patients underwent FN stimulation at the brainstem (proximal) and internal acoustic meatus (distal) using a current intensity of 2 mA. The proximal latency and the P/D amplitude ratio were assessed. House-Brackmann grades I & II indicated good FN function, and grades III to VI were considered fair/poor function. A P/D amplitude ratio > 0.6 was used as a cutoff to indicate a good FN function, while a ratio of ≤ 0.6 indicated a fair/poor FN function. Results The P/D amplitude ratio was measured for all patients, and the calculated sensitivity (SE), specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) were 85.2, 85.7, 88.5, and 81.8%, respectively. The CMAPs from the mentalis muscle were then classified based on their proximal latency into group I (< 6 ms), group II (6-8 ms), and group III (> 8 ms). The SE, SP, PPV, and NPV became 90.5, 90.9, 95, and 83.3%, respectively, in group II. In group I, SE and NPV increased, whereas SP and PPV decreased. While in group III, SP and PPV increased, whereas SE and NPV decreased. Conclusion At a latency between 6 and 8 ms, the P/D amplitude ratio was predictive of outcomes with high SE and SP. When latency was < 6 ms or > 8 ms, the same predictive ability was not observed. Knowing the strengths and limitations is important for understanding the predictive value of the P/D amplitude ratio.

Evaluating Laparoscopic Sleeve Gastrectomy for Morbid Obesity: A Prospective Follow-Up Study.

Background Laparoscopic sleeve gastrectomy (LSG) has become a primary option within bariatric surgery (BS), exhibiting favorable outcomes in terms of weight reduction and improvement of associated health conditions. This study was conducted to assess the outcomes of LSG in morbid obesity (MO) in terms of weight reduction and improvement of comorbidities. Materials and methods A prospective follow-up study was conducted from January 2021 to January 2023 at the Department of Surgery, 7 Air Force Hospital, Kanpur. The study was approved by the institutional ethical committee with protocol no. IEC/612/2020, including 25 patients diagnosed with MO (BMI >40kg/m2) who underwent LSG. Patients were followed up at 1, 3, 6, and 12 months after surgery to track improvements in comorbidities and weight loss. Pre- and post-operative photos were taken, and any complications during the follow-up period were noted. Results Most participants in the study were middle-aged individuals, and 84% of the cohort had common comorbidities such as hypertension (HTN) and diabetes mellitus (DM). LSG led to significant and sustained weight loss, with patients achieving an average reduction of 31.56 kg by the 12th month following the surgery. Moreover, substantial improvements in comorbidities, particularly HTN (76.9%) and DM (80%), were observed. However, not all comorbidities exhibited similar rates of recovery, highlighting the need for tailored management strategies. Using a correlation test, no significant correlation was found between the percentage over ideal body weight (IBW) and the reduction in excess weight, as indicated by a p-value exceeding 0.05. Conclusion LSG is an effective treatment for severe obesity, delivering significant weight loss and notable improvements in metabolic health and overall quality of life.

Long-term Outcomes of Adjunctive Lung Resection for Nontuberculous Mycobacteria Pulmonary Disease.

Background: Adjunctive lung resection is recommended for select patients with nontuberculous mycobacteria (NTM) pulmonary disease (PD). However, data are limited on long-term recurrence rates in patients infected with major pathogens, including Mycobacterium avium complex (MAC) and Mycobacterium abscessus (MABC). Methods: In this prospective observational study, we retrospectively analyzed data from 125 patients with MAC-PD (n = 90) or MABC-PD (n = 35) who underwent adjunctive lung resection. We evaluated microbiological response, postoperative complications, recurrence, and all-cause mortality over a median 80-month follow-up. Results: Persistent culture positivity (64%) was the most common indication for surgery, followed by hemoptysis, recurrent pneumonia, or radiologic deterioration. Postoperative complications occurred in 18 (14%) patients, with no surgery-related deaths. Treatment outcomes did not significantly differ between the MAC- and MABC-PD groups. Cure with culture conversion was achieved in 112 (90%) patients. Recurrence occurred in 37 (33%) of 112 patients, of which 18 (49%) cases were attributed to reinfection by different NTM species or subspecies. The MAC group had higher recurrence rates than the MABC group (Kaplan-Meier curve, log-rank test, P = .043) and was significantly associated with recurrence in the multivariable analysis (adjusted hazard ratio, 2.71; 95% CI, 1.23-5.99). However, mortality was higher in the MABC-PD group than the MAC-PD group (7/35 vs 4/90, P = .006). Conclusions: Adjunctive lung resection with antibiotics helps to reduce bacterial burden and manage symptoms in patients with NTM-PD. However, it does not prevent recurrence, which is mostly caused by reinfection.

Postoperative recovery after suspension suture placement at the site of esophagojejunal anastomosis after total gastrectomy: Comparison of two surgical techniques.

BACKGROUND: Despite improvements, survival rates for gastric cancer remain low, even in developed countries, confirming the role of primary and secondary prevention. OBJECTIVE: This study aims to demonstrate the role of additional suspension sutures on the esophagojejunal anastomosis (EJA) to strengthen the anastomosis, i.e., relieve the mechanical suture. METHODS: A retrospective cohort study was conducted from 2011 to 2022 at the Clinic for Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina. The experimental group consisted of patients placed with a suspension suture at the esophagojejunal anastomosis (EJA) site after total gastrectomy. The control group was patients without a suspension suture. The clinical and laboratory parameters available from the medical history were analyzed, X-ray passage, surgical complications, non-surgical complications, the length of hospitalization, the postoperative course, time of onset of postoperative complications, postoperative radiological follow-up and endoscopic postoperative follow-up were then analyzed. RESULTS: A total of 212 patients were included in the study: 87 in the experimental group with suspension sutures on the EJA and 125 in the control group without suspension sutures on the EJA. The two cohorts did not differ in other clinicopathologic parameters except perineural invasion, which was more prevalent in the control group. Patients in both groups were anemic and elevated values of C reactive protein (CRP) and decreased levels of proteins, albumin and globulin, with no significant difference between the two groups. The most common general complication was pleural effusion (28%), followed by pneumonia (∼22%). The most common complication in the experimental group was an intraabdominal abscess, while in the control group, it was a surgical wound infection. CONCLUSION: Our study did not show a statistically significant difference between the two analyzed EJA techniques created with a circular stapler, when it comes to postoperative course and outcome in patients with gastric cancer.

4 Domain Sports PROM in Spanish: Cross-cultural adaptation in the Chilean population and reliability analysis.

Background Patient-Reported Outcome Measures (PROMs) are tools of increasing interest in the sports population. The purpose of this study was to perform the cross-cultural adaptation and reliability analysis of the 4 Domain Sports Patient-Reported Outcome Measure (4 DSP) into Spanish. Methods A six-stage cross-cultural adaptation protocol was executed to obtain the Spanish version of the 4 DSP (S-4DSP). Subsequently, the questionnaire was administered to a population of 108 postoperative athletes with ACL (Anterior Cruciate Ligament) injuries. The questionnaire was administered again after 30 days. Acceptability, floor and ceiling effects, internal consistency (Cronbach's alpha), and reproducibility (Intraclass Correlation) were evaluated. Results The S-4DSP was fully completed by 108 participants (mean age 34 ± 10.75, 26% women), achieving 100% acceptability. No floor effect was detected. The statistical analysis yielded a global Cronbach's alpha for the questionnaire of 0.65, and domain-specific alphas of 0.88, 0.72, 0.27, and 0.68 for the first, second, third, and fourth domains, respectively. The Intraclass Correlation test reached a maximum of 0.94 and a minimum of 0.48 for the first and fifth questions, respectively. Conclusions The S-4DSP is a reliable and useful tool for evaluating Spanish-speaking athletes after ACL reconstruction.

Linking Patient-Reported Outcome Measure (PROM) Scores to Adverse Event Data to Gain Insight in Overestimation of Postoperative PROM Improvement after Total Hip Arthroplasty and Total Knee Arthroplasty Due to Selective Non-Response.

BACKGROUND: To gain insight into how clinically relevant improvement in Patient-Reported Outcome Measure (PROM) scores after Total Hip (THA) and Total Knee Arthroplasty (TKA) may be under- or overestimated, we compared PROM respondents and non-respondents on their adverse event rates and assessed whether adverse event occurrence was associated with clinically relevant PROM improvement from those without adverse events. METHODS: All primary THAs and TKAs performed in 19 Dutch hospitals between January 2017 and December 2019 were included. The Hip disability and Osteoarthritis Outcome Score-Physical function Short form (HOOS-PS) and Knee injury and Osteoarthritis Outcome Score-Physical function Short form (KOOS-PS) were used to assess the physical function after THA and TKA, respectively. Adverse events included 1-year revision, 30-day readmission, 30-day complications, and long (i.e., > 75th percentile) length-of-stay (LOS). A clinically relevant improvement was defined as at least a 10-point decrease in HOOS-PS and 9 points in KOOS-PS scores. Associations between adverse events and clinically relevant HOOS-PS and KOOS-PS improvement were assessed using binary logistic regression models adjusted for patient characteristics and clustering of patients within hospitals. RESULTS: There were 20,338 THA and 18,082 TKA procedures included. Adverse events mostly occurred more frequently in HOOS-PS and KOOS-PS non-respondents than in respondents. The THA patients experiencing revision, complications, or long LOS were less likely to experience clinically relevant HOOS-PS improvements (odds ratios of 0.11 [0.06 to 0.20], 0.44 [0.30 to 0.63], and 0.66 [0.50 to 0.88], respectively). The TKA patients experiencing revision or long LOS were less likely to experience clinically relevant KOOS-PS improvements (odds ratios of 0.26 [0.12 to 0.55] and 0.63 [0.50 to 0.80], respectively). CONCLUSION: Clinically-relevant HOOS-PS and KOOS-PS improvements are likely overestimated, as non-respondents had higher adverse event rates which were associated with lower likelihood to achieve clinically-relevant HOOS-PS and KOOS-PS improvements.

COVID-19 in patients with haematologic malignancies: effect of RNAemia on clinical outcome in vaccinated patients.

OBJECTIVES: Patients with haematologic malignancies (HM) COVID-19 have more severe disease, with increased risk of mortality. Therefore, this study aimed to evaluate the effect of SARS-CoV-2 RNAemia and the specific humoral immune responses on the clinical outcomes of patients with HM and COVID-19. METHODS: Interferon-α/γ (IFN-α/IFN-γ) serum levels, neutralizing antibodies (NAb), and RNAemia at COVID-19 diagnosis, and persistent RNAemia during the follow-up were evaluated. RESULTS: Overall, 63 (58.9%) out of 107 patients had RNAemia, which was persistent in 26 (41.3%) patients. RNAemia at diagnosis and persistent RNAemia were associated with the need for high-flow nasal oxygen therapy during admission. Persistent RNAemia, age >70 years, and CURB-65 score ≥2 in patients with pneumonia were associated with increased 90-day mortality (p = 0.009, p = 0.030, and p = 0.001, respectively). The 90-day overall survival was lower (p = 0.006) in patients with persistent RNAemia. In addition, dexamethasone administration was associated with a COVID-19 episode with persistent RNAemia. CONCLUSIONS: Our results suggest that in patients with HM, RNAemia at the time of COVID-19 diagnosis and during the follow-up can be used to stratify patients with HM according to their clinical evolution and to guide clinical decisions tailored to the specific needs of each patient.

Chronic endometritis - a constantly discussed issue in infertile women.

OBJECTIVE: A review of current knowledge on the pathophysiology, diagnostic and treatment options for chronic endometritis in infertile women. METHODS AND RESULTS: One of the major causes of failed in vitro fertilization (IVF) is undiagnosed intrauterine pathologies, including chronic inflammation of the uterine mucosa - chronic endometritis. However, some authors relativize the negative impact of chronic endometritis on reproductive outcomes. The etiopathogenesis of chronic endometritis is due to qualitative and quantitative changes in the endometrial microbiome with abnormal multiplication of microorganisms naturally occurring in the uterine cavity or vagina. There is no uniform consensus on the most common pathogen causing chronic endometritis. It is characterized by infiltration of plasma cells into the endometrial stroma outside the menstrual cycle, accompanied by hyperaemia and endometrial oedema. Clinical symptoms are very mild or absent. The diagnosis of chronic endometritis is often difficult because there is no specific clinical or laboratory diagnostic method. The following investigative options are commonly used for the diagnosis of chronic endometritis: diagnostic hysteroscopy, histopathological examination of the endometrium including CD 138 immunohistochemistry and culture from the uterine cavity. However, standardised international hysteroscopic and histopathological criteria for accurate diagnosis of chronic endometritis are still lacking. Empirically administered antibiotic therapy improves the success rate of pregnancy and delivery of a viable foetus in infertile patients with proven chronic endometritis. In addition to reviewing the current knowledge of chronic endometritis, this article discusses the importance of hysteroscopy in the diagnostic process. CONCLUSION: Chronic endometritis is often a clinically silent disease with negative impact on reproduction in infertile women. Although there are still many unresolved issues, the introduction of hysteroscopy into the diagnostic process is important for clinical practice; however, hysteroscopy even in combination with histological examination of the endometrium, often does not allow an unequivocal diagnosis of chronic endometritis. Further prospective randomised studies in a selected group of women with proven chronic endometritis and repeated failure to implant proven euploid embryos should refine this knowledge.

Molecular biomarkers in classic Hodgkin lymphoma.

Classic Hodgkin lymphoma is a unique B-cell derived malignancy featuring rare malignant Hodgkin and Reed Sternberg (HRS) cells that are embedded in a quantitively dominant tumor microenvironment (TME). Treatment of classic Hodgkin lymphoma has significantly evolved in the past decade with improving treatment outcomes for newly diagnosed patients and the minority of patients suffering from disease progression. However, the burden of toxicity and treatment-related long-term sequelae remains high in a typically young patient population. This highlights the need for better molecular biomarkers aiding in risk-adapted treatment strategies and predicting response to an increasing number of available treatments that now prominently involve multiple immunotherapy options. Here, we review modern molecular biomarker approaches that reflect both the biology of the malignant HRS cells and cellular components in the TME, while holding the promise to improve diagnostic frameworks for clinical decision-making and be feasible in clinical trials and routine practice. In particular, technical advances in sequencing and analytic pipelines using liquid biopsies, as well as deep phenotypic characterization of tissue architecture at single-cell resolution, have emerged as the new frontier of biomarker development awaiting further validation and implementation in routine diagnostic procedures.

Performance of HAS-BLED and DOAC scores to predict major bleeding events in atrial fibrillation patients treated with direct oral anticoagulants: A report from a prospective European observational registry.

BACKGROUND: The DOAC score has been recently proposed for bleeding risk stratification of patients with atrial fibrillation treated with direct oral anticoagulants (DOAC). OBJECTIVE: To compare the performance of HAS-BLED and DOAC score in predicting major bleeding events in a contemporary cohort of European AF patients treated with DOAC. METHODS: We included patients derived from a prospective observational registry of European AF patients. HAS-BLED and DOAC scores were calculated as per the original schemes. Our primary endpoint was major bleeding events. Receiver operating characteristic (ROC) curves were used to compare the predictive ability of the scores. RESULTS: A total of 2834 AF patients (median age [IQR] 69 [62-77] years; 39.6 % female) treated with DOAC were included in the analysis. According to the HAS-BLED score, 577 patients (20.4 %) were categorized as very low risk of bleeding, as compared to 1276 (45.0 %) according to DOAC score. A total of 55 major bleeding events occurred with an overall incidence of 1.04 per 100 patient-years. Both scores showed only a modest ability for the prediction of bleeding events (HAS-BLED area under the curve [AUC], 0.65, 95 % confidence interval [CI] 0.55-0.70; DOAC score AUC 0.62, 95 % CI 0.59-0.71, p for difference = 0.332]. At calibration analysis, the DOAC score showed modest calibration, especially for patients at high risk, when compared to HAS-BLED. CONCLUSION: In a contemporary cohort of DOAC-treated AF patients, both HAS-BLED and DOAC scores only modestly predicted the occurrence of major bleeding events. Our results do not support the preferential use of DOAC score over HAS-BLED.

Comparative sensitivity of early cystic fibrosis lung disease detection tools in school aged children.

BACKGROUND: Effective detection of early lung disease in cystic fibrosis (CF) is critical to understanding early pathogenesis and evaluating early intervention strategies. We aimed to compare ability of several proposed sensitive functional tools to detect early CF lung disease as defined by CT structural disease in school aged children. METHODS: 50 CF subjects (mean±SD 11.2 ± 3.5y, range 5-18y) with early lung disease (FEV1≥70 % predicted: 95.7 ± 11.8 %) performed spirometry, Multiple breath washout (MBW, including trapped gas assessment), oscillometry, cardiopulmonary exercise testing (CPET) and simultaneous spirometer-directed low-dose CT imaging. CT data were analysed using well-evaluated fully quantitative software for bronchiectasis and air trapping (AT). RESULTS: CT bronchiectasis and AT occurred in 24 % and 58 % of patients, respectively. Of the functional tools, MBW detected the highest rates of abnormality: Scond 82 %, MBWTG RV 78 %, LCI 74 %, MBWTG IC 68 % and Sacin 51 %. CPET VO2peak detected slightly higher rates of abnormality (9 %) than spirometry-based FEV1 (2 %). For oscillometry AX (14 %) performed better than Rrs (2 %) whereas Xrs and R5-19 failed to detect any abnormality. LCI and Scond correlated with bronchiectasis (r = 0.55-0.64, p < 0.001) and AT (r = 0.73-0.74, p < 0.001). MBW-assessed trapped gas was detectable in 92 % of subjects and concordant with CT-assessed AT in 74 %. CONCLUSIONS: Significant structural and functional deficits occur in early CF lung disease, as detected by CT and MBW. For MBW, additional utility, beyond that offered by LCI, was suggested for Scond and MBW-assessed gas trapping. Our study reinforces the complementary nature of these tools and the limited utility of conventional oscillometry and CPET in this setting.

Endoscopic Evacuation of Acute Subdural Hematomas: A New Selection Criterion.

Introduction Acute subdural hematomas (ASDHs) have a high mortality rate and unfavorable outcomes especially in the elderly population even after surgery is performed. The conventional recommended surgeries by the Brain Trauma Foundation in 2006 were craniotomies or craniectomies for ASDH. As the world population ages, and endoscopic techniques improve, endoscopic surgery should be utilized to improve the outcomes in elderly patients with ASDH. Materials and Methods This was a single-center retrospective report on our series of six patients that underwent endoscopic ASDH evacuation (EASE). Demographic data, the contralateral global cortical atrophy (GCA) score, evacuation rates, and outcomes were analyzed. Results All patients' symptoms and Glasgow Coma Scale improved or were similar after EASE with no complications. Good outcome was seen in 4 (66.7%) patients. Patients with poor outcome had initial low Glasgow Coma Scale scores on admission. The higher the contralateral GCA score, the higher the evacuation rate ( r = 0.825, p ≤ 0.043). All the patients had a GCA score of ≥7. Conclusion EASE is at least not inferior to craniotomy for the elderly population in terms of functional outcome for now. Using the contralateral GCA score may help identify suitable patients for this technique instead of just using a cut-off age as a criteria.

Intracranial pressure monitoring for severe traumatic brain injury: A retrospective study of 273 consecutive patients.

Background: Intracranial pressure (ICP) monitoring is essential in severe traumatic brain injury (sTBI) cases; yet, the frequency of high ICP occurrences remains debated. This study presents a 9-year analysis of ICP monitoring using intraventricular catheters among sTBI patients. Methods: A retrospective review of 1760 sTBI patients (Glasgow Coma Score <9) admitted between January 2011 and December 2019 was conducted. Of these, 280 patients meeting monitoring criteria were included based on Brain Trauma Foundation (BTF) Guidelines. ICP was monitored using intraventricular catheters through right frontal burr holes. Initial ICP readings were recorded intraoperatively, followed by continuous monitoring. Patients with ICP >20 mmHg for 10-15 min during 72 h were categorized with high ICP. Data collected included demographics, computed tomography (CT) findings, intra- and post-operative ICP, and complications. Results: Of 273 patients, 228 were male and 45 females, aged 18-80 (71.30% aged 18-45). Traffic accidents were the primary cause (90.48%). Fifty-two-point seventy-five percent experienced high ICP, correlating significantly with subdural hematoma (P < 0.001), intraventricular hemorrhage (P < 0.013), and compressed basal cisterns (P = 0.046) on initial CT. Twenty patients (7.3%) developed meningitis. Lower mortality rates and improved outcomes were observed in the low ICP group across discharge 3-and 6-month follow-ups. Conclusion: Adherence to BTF guidelines yielded a 52.75% high ICP rate. Significant correlations were found between high ICP and specific CT abnormalities. This study underscores the benefits of ICP monitoring in selected sTBI cases, suggesting a need to review criteria for initiating monitoring protocols.

The Role of Pharmacogenomics Studies for Precision Medicine Among Ethiopian Patients and Their Clinical Implications: A Scoping Review.

Background: Pharmacogenomics research is currently revolutionizing treatment optimization by discovering molecular markers. Medicines are the cornerstone of treatment for both acute and chronic diseases. Pharmacogenomics associated treatment response varies from 20% to 95%, resulting in from lack of efficacy to serious toxicity. Pharmacogenomics has emerged as a useful tool for therapy optimization and plays a bigger role in clinical care going forward. However, in Africa, in particular in Ethiopia, such studies are scanty and not generalizing. Therefore, the objective of this review was to outline such studies, generating comprehensive evidence and identify studied variants' association with treatment responses in Ethiopian patients. Methods: The Joanna Briggs Institute's updated 2020 methodological guidelines for conducting and guidance for scoping reviews were used. We meticulously adhered to the systemic review reporting items checklist and scoping review meta-analyses extension. Results: Two hundred twenty-nine possibly relevant studies were searched. These include: 64, 54, 21, 48 and 42 from PubMed, Scopus, Google Scholar, EMBASE, and manual search, respectively. Seventy-seven duplicate studies were removed. Thirty-nine papers were rejected with justification, whereas 58 studies were qualified for full-text screening. Finally 19 studies were examined. The primary pharmacogene that was found to have a significant influence on the pharmacokinetics of efavirenz was CYP2B6. Drug-induced liver injury has frequently identified toxicity among studied medications. Conclusion and Future Perspectives: Pharmacogenomics studies in Ethiopian populations are less abundant. The studies conducted focused on infectious diseases, specifically on HAART commonly efavirenz and backbone first-line anti-tuberculosis drugs. There is a high need for further pharmacogenomics research to verify the discrepancies among the studies and for guiding precision medicine. Systematic review and meta-analysis are also recommended for pooled effects of different parameters in pharmacogenomics studies.
