Uso y complicaciones del cateterismo urinario en salas de cuidados moderados de un hospital universitario

Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.

Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.

Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.

Intraoperative Challenge: Managing Venous Air Embolism During Sitting Craniotomy.

Venous air embolism (VAE) represents a rare yet potentially life-threatening complication encountered during neurosurgical procedures, particularly craniotomy. Here, we present a case of a 30-year-old male undergoing excision of a cerebellar abscess who developed VAE midway through the procedure. Immediate recognition and intervention were paramount in managing the embolism effectively, ensuring a favorable surgical outcome. Vigilant monitoring, prompt cessation of the procedure, and implementation of preventive measures such as oxygen therapy and venous air aspiration were pivotal in mitigating the embolism's effects. This study underscores the critical importance of intraoperative vigilance, preparedness, and multidisciplinary teamwork in addressing rare but potentially catastrophic complications during neurosurgical interventions.

Long-term retention and survival of cemented implant-supported zirconia and metal-ceramic single crowns: A retrospective study.

OBJECTIVES: To evaluate the effect of different cement types on the incidence of failure and loss of retention of zirconia and metal-ceramic single crowns (SCs) cemented on implant abutments. METHODS: We placed 567 implant-supported SCs in 358 patients and retrospectively evaluated long-term retention for up to 12.8 years. The frameworks were made from metal alloy (n = 307) or zirconia (n = 260). SCs were cemented with permanent (glass-ionomer cement; n = 376) or semipermanent cement (zinc oxide non-eugenol cement; n = 191) on standardized (n = 446) or customized (n = 121) abutments. Kaplan-Meier curves were used to calculate the incidence of decementation. Differences between survival curves were assessed with log-rank tests. Cox-regression analysis was performed to evaluate multiple risk factors. RESULTS: Of the 567 SCs, 22 failed because of technical complications and four because of implant loss. Loss of retention was observed in 50 SCs. Analysis revealed a 7% probability of loss of retention for zirconia and 16% for metal-ceramic SCs after 10 years (p = .011). After 5 years, loss of retention was higher for standardized abutments than for customized abutments (p = .014). The probability of loss of retention was higher with semipermanent than with permanent cement (p = .001). Cox-regression analysis revealed semipermanent cement as the only significant risk factor for SC failure (p = .026). CONCLUSIONS: In contrast to semipermanent cement, permanent cement provides acceptable long-term retention of cemented implant-supported SCs. These possible positive effects of customized abutments have to be controlled with larger sample sizes.

Cardiovascular complications during delivery hospitalizations in inflammatory bowel disease patients.

BACKGROUND: The relationship between inflammatory bowel disease (IBD) and cardiovascular outcomes among pregnant women has yet to be thoroughly investigated. Our aim is to assess the odds of cardiovascular disease and cardiac arrhythmias during hospital admissions for delivery and identify contributing factors associated with cardiovascular complications in pregnant women with IBD. METHODS: We performed a retrospective analysis of data from the National Inpatient Sample, obtained from delivery admissions of pregnant women with and without IBD, identified via International Classification of Diseases codes, from 2009 to 2019. Using a regression model, we compared the odds of cardiovascular complications between these two groups, adjusting for traditional cardiovascular risk factors as confounding variables. RESULTS: Our study included 71,361 pregnancies with IBD and 41,117,443 pregnancies without this condition. The incidence of IBD in pregnancy rose near three-fold increase over the decade. In comparison to pregnancies without IBD, those involving pregnant patients with IBD exhibited an increased likelihood of encountering cardiovascular complications, with an adjusted odds ratio (AOR) of 1.37 (95% CI, 1.29-1.46). This heightened risk encompasses a range of conditions, including peripartum cardiomyopathy (AOR, 9.45; 95% CI, 3.86-23.15), cardiac arrhythmias (AOR, 2.03; 95% CI, 1.59-2.60), and hypertensive disorders of pregnancy (AOR, 1.51; 95% CI, 1.37-1.66), notably preeclampsia, eclampsia, and the syndrome of hemolysis, elevated liver enzymes, and low platelet count (HELLP syndrome). Pregnancies with IBD were also associated with three-fold higher odds of venous thromboembolism (AOR, 3.91; 95% CI, 1.45-10.48). CONCLUSIONS: Pregnant patients with IBD had an increased odds of cardiovascular complications during delivery admissions, independent of traditional cardiovascular risk factors. Further research is needed to elucidate the underlying mechanisms and develop targeted prevention strategies for this high-risk population.

Beyond the revised atlanta classification: a comprehensive review of the imaging assessment of acute pancreatitis and its complications.

While the Revised Atlanta Classification outlines the primary complications of acute pancreatitis, it is crucial to recognize additional factors that contribute to morbidity and mortality associated with acute pancreatitis. In this review, we discuss the imaging-based classification and staging of acute pancreatitis as described by the Revised Atlanta Classification, but also provide a comprehensive understanding of the pancreatic anatomy and its relation to surrounding structures, which is essential for imaging-based assessment of both acute pancreatitis and its complications. We further extend the discussion beyond common complications such as pseudocysts and walled-off necrosis to include lesser-known but significant complications such as peripancreatic infection, disconnected ductal disconnection syndrome, thrombosis, hemorrhage, and gastrointestinal complications. Additionally, illustrative examples are presented to highlight relevant points pertaining to real-life imaging assessment of acute pancreatitis and its complications.

Genetic Correlation of HBB, HFE and HAMP Genes to Endocrinal Complications in Egyptian Beta Thalassemia Major Patients.

Iron loading is regarded as the primary cause of endocrine abnormalities in thalassemia major patients. Thus, the purpose of the current research was to explore the impact of thalassemia genotypes, hepcidin antimicrobial peptide (HAMP) and hereditary hemochromatosis (HFE) gene variants, and hepcidin expression on serum ferritin and endocrinal complications in thalassemia patients. The study comprised fifty beta-thalassemia cases and fifty age- and sex-matched controls. Genotyping of the Beta-globin gene (HBB), HAMP, and exon 2 of the HFE gene was performed using Sanger sequencing. C282Y (c.845G > A) variant of the HFE gene was determined by PCR-RFLP. Hepcidin mRNA expression was assessed by qRT-PCR. Biochemical and hormonal studies were done for all patients. Hypogonadism and short stature were found in 56% and 20% of the investigated cases, respectively. Molecular studies reported a statistically higher frequency of the HAMP variant c.-582A > G in thalassemic patients than controls. Significant downregulation of hepcidin expression was found in cases compared to healthy subjects that was significantly associated with short stature. Considering the thalassemia alleles, the IVSI.1G > A (ß0) allele was statistically related to hypogonadism. Our results proposed that thalassemia genotypes and downregulated hepcidin expression were the potential risk factors for endocrinopathies in our cases. We also demonstrated an increased incidence of the HAMP promoter variant c.- 582A > G that might have a role in the pathogenesis of iron overload in thalassemic cases. Significant downregulation of hepcidin expression, that contributes to increased iron burden, could be used as a future therapeutic target in these patients.

Effect of perinatal consumption of low-calorie sweetener on maternal health: A systematic review and meta-analysis.

BACKGROUND AND AIMS: Evidence regarding perinatal low-calorie (or artificial) sweetener (LCS) consumption and its effect on maternal health outcomes is limited and inconclusive. The primary outcomes of our systematic review and meta-analysis were the effect of preconception and pregnancy LCS exposure on reproductive and pregnancy outcomes. Secondary outcomes included long-term maternal health. METHODS: A systematic search of electronic databases, including PubMed, Embase, CINAHL, the Cochrane Library, Scopus, Web of Science, PsycINFO, ProQuest Health and Medical, ClinicalTrials.gov and Google Scholar, was conducted up to 20 November 2023. Primary studies, including clinical trials, cohort studies, case-control studies, which reported any LCS consumption during perinatal period and pregnancy and maternal health outcomes were eligible. A random effects model with restricted maximum likelihood estimation was used for the meta-analysis. We appraised the quality of the included studies using the National Institute of Health study quality appraisal tool and the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation tool. RESULTS: A total of 19 eligible studies with 203,706 participants were included. LCS consumption during pregnancy was associated with 11% increased risk of preterm birth (RR = 1.11, 95% CI: 1.07-1.16, I2 = 0.01%) and 42% increased risk of gestational diabetes (RR = 1.42, 95% CI: 0.98-2.04, I2 = 67.60%) compared with no consumption, however, the effect size for gestational diabetes was not precise as the 95% CI indicated that the effect estimate could range from 2% lower risk to 204% (or 2.04 times) higher risk. We found no association between LCS consumption during pregnancy and gestational weight gain (standardized mean difference (SMD) = 0.04; 95% CI: -0.17 - 0.24, I2 = 41.31%) or gestational age at birth (SMD = 0.00; 95% CI: -0.13 - 0.14, I2 = 80.13%). The effect of LCS consumption on reproductive treatment outcomes were inconsistent. CONCLUSIONS: Based on the evidence available, LCS consumption in pregnancy was associated with increased risk of preterm birth and gestational diabetes. Robust research, such as well-designed randomized trials and large prospective cohort studies, is required to confirm the causal effect of LCS consumption during perinatal period on adverse maternal health outcomes.

Stratifying risk of failure to achieve textbook outcomes among patients undergoing hepatectomy for hepatocellular carcinoma: A multicenter score validation study.

BACKGROUND AND AIMS: The concept of textbook outcomes (TOs) has gained increased attention as a critical metric to assess the quality and success of outcomes following complex surgery. A simple yet effective scoring system was developed and validated to predict risk of not achieving textbook outcomes (non-TOs) following hepatectomy for hepatocellular carcinoma (HCC). METHODS: Using a multicenter prospectively collected database, risk factors associated with non-TO among patients who underwent hepatectomy for HCC were identified. A predictive scoring system based on factors identified from multivariate regression analysis was used to risk stratify patients relative to non-TO. The score was developed using 70 % of the overall cohort and validated in the remaining 30 %. RESULTS: Among 3681 patients, 1458 (39.6 %) failied to experience a TO. Based on the derivation cohort, obesity, American Society of Anaesthesiologists score(ASA score), Child-Pugh grade, tumor size, and extent of hepatectomy were identified as independent predictors of non-TO. The scoring system ranged from 0 to 10 points. Patients were categorized into low (0-3 points), intermediate (4-6 points), and high risk (7-10 points) of non-TO. In the validation cohort, the predicted risk of developing non-TOs was 39.0 %, which closely matched the observed risk of 39.9 %. There were no differences among the predicted and observed risks within the different risk categories. CONCLUSIONS: A novel scoring system was able to predict risk of non-TO accurately following hepatectomy for HCC. The score may enable early identification of individuals at risk of adverse outcomes and inform surgical decision-making, and quality improvement initiatives.

Measuring the impact of specific surgical complications after ovarian cancer cytoreductive surgery on short-term outcomes.

OBJECTIVE: We sought to measure the impact of specific peri-operative complications after primary cytoreductive surgery on relevant patient outcomes and use of resources. METHODS: A cohort of patients with advanced ovarian cancer who underwent primary cytoreductive surgery at two institutions (2006-2016) were studied. Specific known complications ('exposures') within 30 days of surgery were evaluated to determine the impact on outcomes. Exposures included bowel leak, superficial surgical site infection, deep surgical site infection, venous thromboembolic event, and cardiac event. Outcomes were prolonged lengths of stay, readmission or non-home discharge, reoperation, organ failure, delay to adjuvant chemotherapy, and 90-day mortality. Population attributable risk (PAR) was used to estimate the proportion of adverse outcomes that could be prevented by elimination of a causal exposure and considers both the strength of the association and the prevalence of the complication; adjusted PARs (aPAR) were calculated using adjusted relative risks (aRR) adjusted for stage (IIIC vs IV) and American Society of Anesthesiology score (<3 vs ≥3). RESULTS: A cohort of 892 patients was included. Each of the evaluated exposures had an impact on readmission/non-home discharge (aPAR range 5.3 to 13.5). A venous thromboembolic event was significantly associated with 90-day mortality (aRR=2.9 (95% CI 1.3 to 6.7); aPAR=8.6 (95% CI -1.8 to 19.1)) and organ failure (aRR=4.7 (95% CI 2.3 to 9.5); aPAR=13.9 (95% CI 2.8 to 25.1)). Similarly, a cardiac event was most strongly associated with organ failure and was very impactful (aPAR=19.0 (95% CI 6.8 to 31.1)).Bowel leak was a major contributor to poor outcome, including reoperation (aPAR=45.5 (95% CI 34.3 to 56.6)), organ failure (aPAR=13.6 (95% CI 2.6 to 24.6)), readmission/non-home discharge (aPAR=5.3 (95% CI 1.6 to 9.0)), delay to adjuvant chemotherapy (aPAR=5.9 (95% CI 2.3 to 9.4)), and prolonged lengths of stay (aPAR=13.0 (95% CI 9.1 to 16.9)). CONCLUSION: Going beyond reporting complications using common scales to measure their genuine impact provides important information for providers, patients, and payers. We report that less frequent exposures, including a venous thromboembolic event, cardiac events, and bowel leaks, have a high impact on patients and use of resources.

A comparative cohort study of surgical approaches for adult spinal deformity at a minimum 2-year follow-up.

STUDY DESIGN: This study was a retrospective multi-center comparative cohort study. MATERIALS AND METHODS: A retrospective institutional database of operative adult spinal deformity patients was utilized. All fusions > 5 vertebral levels and including the sacrum/pelvis were eligible for inclusion. Revisions, 3 column osteotomies, and patients with < 2-year clinical follow-up were excluded. Patients were separated into 3 groups based on surgical approach: 1) posterior spinal fusion without interbody (PSF), 2) PSF with interbody (PSF-IB), and 3) anteroposterior (AP) fusion (anterior lumbar interbody fusion or lateral lumbar interbody fusion with posterior screw fixation). Intraoperative, radiographic, and clinical outcomes, as well as complications, were compared between groups with ANOVA and χ2 tests. RESULTS: One-hundred and thirty-eight patients were included for study (PSF, n = 37; PSF-IB, n = 44; AP, n = 57). Intraoperatively, estimated blood loss was similar between groups (p = 0.171). However, the AP group had longer operative times (547.5 min) compared to PSF (385.1) and PSF-IB (370.7) (p < 0.001). Additionally, fusion length was shorter in PSF-IB (11.4) compared to AP (13.6) and PSF (12.9) (p = 0.004). There were no differences between the groups in terms of change in alignment from preoperative to 2 years postoperative. There were no differences in clinical outcomes. While postoperative complications were largely similar between groups, operative complications were higher in the AP group (31.6%) compared to the PSF (5.4%) and PSF-IB (9.1) groups (p < 0.001). CONCLUSION: While there were differences in intraoperative outcomes (operative time and fusion length), there were no differences in postoperative clinical or radiographic outcomes. AP fusion was associated with a higher rate of operative complications.

Clinical-laboratory characteristics predictive of COVID-19 severity: a prospective hospital cohort, in Pernambuco, Northeast Brazil.

OBJECTIVE: To describe the clinical-laboratory profile and analyze the factors associated with the severity of COVID-19. METHODS: A prospective cohort study involving patients with COVID-19 admitted to a tertiary hospital in Recife, Brazil. All cases were confirmed by RT-PCR and classified according to severity criteria. A descriptive statistical analysis of the population's characteristics was conducted. Risk factors associated with the outcome of the case according to severity were analyzed by calculating the odds ratio (OR) using the general equation estimation (GEE) model. RESULTS: Among the 75 cases included, 64% were female, and 62.7% were aged 65 years or older. The median length of stay was 9 days (6 - 14). Hypertension (65.3%) and Diabetes Mellitus (36%) were the most frequent comorbidities. Severe forms of COVID-19 constituted 41.3% of the sample. The factors associated with severity were a history of asthma (OR=4.58, 95%CI:1.13 - 18.7), report of anorexia (OR=1, 12, 95%CI:1.01-1.24), and laboratory changes that included elevated platelets (OR=1.00, 95% CI:1.00-1.01), elevated D'Dimer (OR=1, 26, 95% CI:1.04-1.52), elevated aspartate aminotransferase (OR=1.00, 95% CI:1.00-1.01), and gamma-glutamyl transferase (OR=1.22, IC95 %:0.98-1.51), hypernatremia (OR=1.31, 95%CI:1.12-1.52), and hyperkalemia (OR=1.21, 95% CI:1.04-1.41). CONCLUSION: Multisystemic involvement with a tendency for thrombophilia, electrolyte disturbances, and hepatic aggression, reflected by laboratory changes, were factors associated with the severity of COVID-19.

Retrospective analysis of the effects of impacted third molar on hematologic patients undergoing hematopoietic stem cell transplantation.

Objective: This study aimed to investigate the incidence, treatment status, and impact position of impacted third molars (ITM) and their effects on patients undergoing hematopoietic stem cell transplantation (HSCT). Methods: A retrospective analysis was conducted on the medical records of 454 patients who underwent HSCT, out of which 188 patients had ITM. The presence of ITM and its association with transplant-related infections and complications were recorded and analyzed. Results: Patients with ITM were significantly younger. The number of mandibular ITM was notably higher than maxillary ones, and the risk of pericoronitis in mandibular ITM was significantly higher than in maxillary ones. Out of 311 ITM in 188 patients, 25 were extracted before transplantation. The proportion of extraction and treatment for ITM with pericoronitis or caries was significantly higher than that for ITM without such problems. Moreover, patients with a history of pre-transplant pericoronitis had a significantly higher probability of developing tooth-related complications during transplantation, caused by pericoronitis in ITM compared to patients without a history of pericoronitis. Conclusion: Pre-transplant examination and treatment of ITM are essential, especially in cases with a history of pericoronitis. Oral intervention can significantly reduce the occurrence of tooth-related complications related to ITM during transplantation.

Clinicopathological study of otomycosis in a tertiary hospital in South-west Nigeria.

Background: Otomycosis is common in environments with hot, humid weather, and it may be challenging to manage. Objectives: To profile common clinical presentations, the pathogenic fungi, the treatment modalities with responses, and explore clinical factors associated with having positive fungal culture in Otomycosis. Methods: Retrospective review of patients with Otomycosis. Demographic and clinical parameters, otoscopic findings and mycological study results were recorded. The treatment modalities used and treatment response were summarized. Comparative statistical analyses of associated factors to positive fungal culture were performed with Chi square test, and Student's t-test, using SPSS version 22.0. Results: Total of 71 patients with M: F=1:1.8, mean age 38.5±19.8 years. Average duration of symptoms was 5.4 ±4.6 weeks; common presenting complaint was itchy ear (33.8%). Majority of patients (85.9%) had unilateral ear involvement, 50.0% applied ototopic medications before presentation, 8.5% had multiple co-morbidities. 20 patients had positive fungal culture results; common fungal isolate was Aspergillus niger 9 (45.0%).Clinical factors associated with positive culture of fungus were age, non-previous use of ototopic drugs, and presence of co-morbidity. The most common treatment was local ear debridement and use of topical antifungal creams. Majority (91.5%) of the patients responded with resolution of fungal infection. Complications rate was 8.4%. Conclusions: Otomycosis commonly present with itchy ears, the pathogenic fungi commonly being Aspergillus species. The factors associated with positive fungal culture were age, non-usage of ototopic agents and presence of co-morbidity. Treatment modality used was local debridement and topical antifungal agents, which produced favourable response in most patients.

Curosurf surfactant application on preterm babies with respiratory complications-health-economic benefits.

Background: The implementation of surfactant for respiratory syndrome approbates the therapy as a revolutionary method in intensive neonatal therapy and respiratory resuscitation. It is important to investigate the costs of this treatment. Objective: The aim of the study is to analyze the data by the application of the surfactant Curosurf to preterm babies with respiratory complications and describe the treatment costs, healthcare resource utilization and evaluate economic benefits of surfactant use in the treatment of neonates with respiratory distress syndrome (RDS) and hyaline-membrane disease (HDM). Methods: A retrospective survey was performed covering 167 babies based on respiratory complications due to preterm birth and the necessity to apply a surfactant therapy. A documentary method was implemented and for each patient, an individual research protocol was filled out - a questionnaire created specifically for the purposes of the study. Results and discussion: An analysis of the data from the application of CUROSURF was made and the obtained therapeutic results were compared to expenditures for the therapy, short-term therapeutic effect, benefits and consequences of the therapy of preterm newborns with respiratory complications. The application of CUROSURF to babies with RDS resulted in the realization of net savings due to the elimination of the necessity of conducting several diagnostic and therapeutic procedures as well as their duration reduction of hospital stay, thus defining its health-economic benefits. Conclusions: The models of evaluation of cost effectiveness reveal that the medicinal product is expensive but effective from the aspect of short-term therapeutic results.

Evaluation of demographic/clinical features and hemorrhagic complications in patients with ischemic stroke who underwent reperfusion therapy.

The relationship between demographic/clinical characteristics, clinical outcomes and the development of hemorrhagic complications in patients with ischemic stroke who underwent reperfusion therapy has not been studied sufficiently. We have aimed to compare genders and age groups in terms of clinical features and outcome; and types of reperfusion treatments and clinical features regarding the development of hemorrhagic complications in patients with ischemic stroke who underwent recombinant tissue plasminogen activator (rtPA) and/or thrombectomy. Patients with acute ischemic stroke undergoing rtPA and/or thrombectomy were divided into six age groups. Parameters including hemorrhagic complications, anticoagulant and antiaggregant use, hyperlipidemia, smoking status, biochemical parameters, and comorbidities were documented. National Institutes of Health Stroke Scale (NIHSS) scores, modified Rankin Score (mRS) and Glasgow Coma Scale scores were recorded. Etiological classification of stroke was done. These parameters were compared in terms of age groups, genders, and hemorrhagic complications. Significant differences were found between age groups concerning hypertension, coronary artery disease, smoking status, and antiaggregant use. Rate of hemorrhagic complications in rtPA group was significantly lower when compared with other treatment groups. Hemorrhagic complications developed mostly in the rtPA+thrombectomy group. Among the patients who developed hemorrhagic complications, NIHSS scores on admission were found to be significantly lower in men than women. Admission, discharge, and 3rd month mRS values in men were significantly lower than those of women. Knowing demographic and clinical features of patients that may have an impact on the clinical course of ischemic stroke managed with reperfusion therapy will be useful in predicting the hemorrhagic complications and clinical outcomes.

Lissencephaly and Advanced-Stage Congenital Cytomegalovirus Infection in a Neonate.

This case report investigates the management of a 24-week-old neonate with congenital cytomegalovirus (CMV) infection and its sequelae, including severe intrauterine growth restriction, thrombocytopenia, and brain anomalies, ultimately progressing to lissencephaly. The diagnostic challenges included delayed clinical suspicion of congenital CMV, which was not identified until after delivery through CMV DNA polymerase chain reaction, and differentiating its symptoms from other potential causes of the neonate's condition. Aggressive interventions included antibiotics, antiviral therapy with ganciclovir, and supportive measures such as intubation, CPR, respiratory support, blood transfusions, and management of coagulopathy. Despite these efforts, the patient deteriorated due to progressive hypoperfusion, hypoxemic cardiorespiratory failure, and disseminated intravascular coagulopathy. Due to the poor prognosis and extent of multiorgan damage, support was withdrawn per parental consent. This case highlights the complications encountered when managing an advanced-stage neonatal CMV infection and emphasizes the importance of a multidisciplinary and holistic approach to guide diagnosis and treatment.

Transcranial Doppler in the Detection of Cerebral Vasospasm After Subarachnoid Hemorrhage.

Background Transcranial Doppler (TCD) is a simple, noninvasive, nonionizing, portable technique but not widely practiced to detect cerebral vasospasm after subarachnoid hemorrhage (SAH). Objective The aim of this study was to assess the performance of TCD in the detection of cerebral vasospasm in patients with SAH considering CT angiography (CTA) as a gold standard. Methods and material This cross-sectional study included 50 patients with acute SAH admitted to the National Institute of Neurosciences & Hospital (NINS & H), Dhaka, Bangladesh, from February to June 2021. The neurological status, severity of SAH, and initial CT findings were recorded. All patients were screened for cerebral vasospasm with TCD on the 4th, 7th, 10th, and 14th days after the event. Screening of cerebral vasospasm by CTA was done on the 14th day of the event or earlier if TCD suggested vasospasm. Results The mean age of the participants was 51.4 ±13.4 years (mean ± SD), and females were predominant (N=29, 58%). CTA detected cerebral vasospasm in 18 (36%) participants, but TCD could detect it in only 13 (26%) cases. Among the participants who had no vasospasm by CTA, all but one were also found to have no vasospasm by TCD. The agreement between TCD and CTA in detecting cerebral vasospasm was significant (p<0.001, κ=0.726). TCD shows good specificity (96.9%) and positive predictive value (92.8%), but sensitivity (72.2%) and negative predictive value (81.6%) were comparatively lower. Overall, the diagnostic accuracy of TCD in detecting cerebral vasospasm was 88%. Conclusions Although compared to CTA, TCD is a highly specific but less sensitive tool in detecting vasospasm, TCD remains a reliable screening tool for detecting vasospasm following SAH.

The influence of osteoporosis on mechanical complications in lumbar fusion surgery: a systematic review.

Background: Adults undergoing spine surgery often have underlying osteoporosis, which may be a risk factor for postoperative complications. Although these associations have been described, osteoporosis remains profoundly underdiagnosed and undertreated in the spine surgery population. A thorough, comprehensive systematic review summarizing the relationships between bone mineral density (BMD) and specific complications of lumbar fusion surgery could be a valuable resource for raising awareness and supporting clinical practice changes. Methods: PubMed, Embase, and Web of Science databases were searched for original clinical research articles reporting on BMD, or surrogate measure, as a predictor of complications in adults undergoing elective lumbar fusion for degenerative disease or deformity. Endpoints included cage subsidence, screw loosening, pseudarthrosis, vertebral fracture, junctional complications, and reoperation. Results: A total of 71 studies comprising 12,278 patients were included. Overall, considerable heterogeneity in study populations, methods of bone health assessment, and definition and evaluation of clinical endpoints precluded meta-analysis. Nevertheless, low BMD was associated with higher rates of implant failures like cage subsidence and screw loosening, which were often diagnosed with concomitant pseudarthrosis. Osteoporosis was also a significant risk factor for proximal junctional kyphosis, particularly due to fracture. Many studies found surgical site-specific BMD to best predict focal complications. Functional outcomes were inconsistently addressed. Conclusions: Our findings suggest osteoporosis is a significant risk factor for mechanical complications of lumbar fusion. These results emphasize the importance of preoperative osteoporosis screening, which allows for medical and surgical optimization of high-risk patients. This review also highlights current practical challenges facing bone health evaluation in patients undergoing elective surgery. Future prospective studies using standardized methods are necessary to strengthen existing evidence, identify optimal predictive thresholds, and establish specialty-specific practice guidelines. In the meantime, an awareness of the surgical implications of osteoporosis and utility of preoperative screening can provide for more informed, effective patient care.

Multiple myeloma and infections in the era of novel treatment modalities.

Infections are major cause of morbidity and mortality in patients with multiple myeloma. Current treatment landscape of newly-diagnosed multiple myeloma includes different classes of drugs, such as proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies, all of which are characterized by specific risk and pattern of infectious complications. Additionally, autologous and allogeneic hematopoietic cell transplantation, widely used in the treatment of multiple myeloma, are complex procedures, carrying a significant risk of complications, and mainly infections. Finally, novel treatment modalities such as bispecific T-cell engagers and chimeric antigen receptor T-lymphocytes have been changing the paradigm of myeloma treatment in relapsed-refractory setting. These agents due to unique mechanism of action carry distinct pattern of infectious complications. In this review, an attempt has been made to summarize the incidence, risk factors, and patterns of infections during different stages of myeloma treatment including novel treatment modalities, and to provide evidence underlying the current concept of infectious disease prophylaxis in this category of patients.
