Navigating Human Epidermal Growth Factor Receptor 2 (HER2) Conversion: Insights From Recurrent Breast Cancer.

Recurrent breast cancer presents clinical challenges due to its dynamic nature. Turning human epidermal growth factor receptor 2 (HER2) status from negative to positive upon recurrence is a rare but clinically significant phenomenon that can impact treatment decisions. We present the case of a 63-year-old female initially diagnosed with stage IIIA breast cancer, characterized as HER2-negative. However, upon recurrence eight years later, the patient exhibited HER2 conversion, indicating a positive status. Subsequent treatment adjustments were made based on this new HER2-positive status, leading to complete remission. HER2 conversion underscores the dynamic nature of tumor biology in recurrent breast cancer. This case highlights the importance of re-biopsy for accurate biomarker assessment and the necessity of personalized treatment strategies based on current molecular profiles. Understanding and recognizing HER2 conversion in recurrent breast cancer is crucial for optimizing patient outcomes and guiding clinical management decisions. Further research is warranted to elucidate the frequency and clinical implications of HER2 conversion in recurrent breast cancer.

This editorial highlights the intricate relationship between the dream worlds created in sleep and the virtual landscapes we explore in Minecraft, highlighting how both territories are constructed from the building blocks of our subconscious mind. It emphasizes the role of dreams as simulators for real-life events, particularly in mitigating potential risks, much like Minecraft allows players to engage in risk-free exploration and problem-solving within its pixelated universe. In addition, this editorial aims to illuminate the functions of dreams in memory consolidation, emotional processing, and brain development while showcasing the importance of creativity and imagination in enhancing our mental health and understanding of reality.

Outcome of creating clustering nursing care and healing environment on premature infants' behavioural outcomes.

We conducted a quasi-experimental study in two neonatal intensive care units (NICUs) from January to July 2021, focusing on the effects of clustering nursing care and creating a healing environment on premature infants' behavioural outcomes. The study included 106 infants, with 53 in both the study and control groups. Significant improvements were observed in organisation state/sleep and responsiveness/interaction domains in the study group, along with shorter hospital stays and greater weight gain on discharge. These findings highlight the positive impact of targeted interventions on premature infants' developmental outcomes, emphasising the need for comprehensive care strategies in NICU settings.

Machine learning insights on intensive care unit-acquired weakness.

Intensive care unit-acquired weakness (ICU-AW) significantly hampers patient recovery and increases morbidity. With the absence of established preventive strategies, this study utilizes advanced machine learning methodologies to unearth key predictors of ICU-AW. Employing a sophisticated multilayer perceptron neural network, the research methodically assesses the predictive power for ICU-AW, pinpointing the length of ICU stay and duration of mechanical ventilation as pivotal risk factors. The findings advocate for minimizing these elements as a preventive approach, offering a novel perspective on combating ICU-AW. This research illuminates critical risk factors and lays the groundwork for future explorations into effective prevention and intervention strategies.

The Pleural Origin of Retiform Hemangioendothelioma: An Unusual Origin of a Rare Diagnosis.

Introduction: Vascular malignancies are categorized into benign hemangiomas, malignant angiosarcomas, and tumors of intermediate malignancy. Retiform hemangioendothelioma (RH) is one of the rare diagnoses belonging to the class of intermediate malignancies that was initially diagnosed. Case Presentation: In this case report, we have reported a rare case of RH, a locally aggressive, vascular tumor of malignant potential presenting at an unusual site. The most observed locations of this soft tissue tumor are skin and subcutaneous tissues of extremities; however, this case of RH was observed in an unusual site called pleura, which is a rare occurrence related to this tumor. The presence of cell surface markers like CD31 and ERG of vascular and endothelial origin and the presence of hobnail appearance of endothelial channels on the biopsy profile supported the vascular origin of the tumor; the clinical features and imaging studies further confirmed the diagnosis of RH. Conclusion: In this case report, a rare case of RH with an unusual site of origin was highlighted. RH is a vascular neoplasm; commonly observed sites of this vascular tumor were skin and subcutaneous tissue of the extremities; however, in this case, the site was unusually different, which was the pleura of the left lung.

Health education intervention and its impact on patients with unilateral vestibular dysfunction: An information-motivation-behavioral model approach.

Unilateral vestibular dysfunction is a one-sided impairment of vestibular function in one ear. Incorporating health education in treatment and rehabilitation plans can improve vestibular function, keep negative emotions at bay, and reduce the extent of the condition. This letter investigates the impact of the information-motivation-behavioral skills model as a medium for health education on patient outcomes. While offering encouraging observations, there are certain limitations, such as the study's retrospective design, small sample size, use of subjective measures, and lack of longer follow-ups that challenge the cogency of the study. The study is a step toward transforming vestibular dysfunction treatment through health education.

Intravenous iron therapy for heart failure and iron deficiency: An updated meta-analysis of randomized clinical trials.

Heart failure (HF) patients frequently exhibit iron deficiency, which is associated with a poor prognosis. Although various trials have been conducted, it is uncertain if intravenous (IV) iron replenishment improves clinical outcomes in HF patients with iron deficiency. A comprehensive literature search was conducted using PubMed/MEDLINE, Embase, and the Cochrane Library from inception till 15 September 2023 to retrieve randomized controlled trials (RCTs) that compared IV iron therapy with placebo or standard of care in patients with HF and iron deficiency. Clinical outcomes were assessed by generating forest plots using the random-effects model and pooling odds ratios (ORs) or weighted mean differences (WMDs). Fourteen RCTs with 6651 patients were included. IV iron therapy showed a significantly reduced incidence of the composite of first heart failure hospitalization (HHF) or cardiovascular (CV) mortality as compared with the control group (OR = 0.73, 95% CI: 0.58 to 0.92). The IV iron therapy resulted in a trend towards lower CV mortality (OR = 0.88, 95% CI: 0.76 to 1.01), 1-year all-cause mortality (OR = 0.85, 95% CI: 0.71 to 1.02), and first HHF (OR = 0.73, 95% CI: 0.51 to 1.05), and an improved left ventricular ejection fraction (LVEF) (MD = 4.54, 95% CI: -0.13 to 9.21). Meta-regression showed a significant inverse moderating effect of baseline LVEF on the first HHF or CV death. In patients with HF and iron deficiency, IV iron therapy reduced the incidence of composite of first HHF or CV mortality. There was a trend of lower overall CV and 1-year all-cause mortality, first HHF, and improved LVEF with IV iron therapy.

Chronic Myeloid Leukemia in Adolescents and Young Adults: Clinicopathological Variables and Outcomes.

INTRODUCTION: Adolescents and young adults (AYAs) diagnosed with chronic myeloid leukemia (CML) constitute a significant demographic group, particularly in regions with youthful populations like Qatar. Despite the global median age of CML diagnosis being 65 years, Qatar's age distribution reflects a younger cohort. This study investigates whether AYAs with CML exhibit distinct clinicopathological characteristics or outcomes compared to older age groups. METHODS: A total of 224 CML patients were enrolled, including 114 AYAs (defined as ages 15 through 39). Demographic and clinical parameters, including gender, BMI, BCR-ABL1 transcript type, white blood cell (WBC) count, hemoglobin level, platelet count, and spleen size, were compared between AYAs and older patients. Prognostic scoring systems (Sokal, Hasford, EUTOS, and ELTS) and molecular response rates (MMR and DMR) were also evaluated. RESULTS: AYAs demonstrated higher WBC counts at diagnosis (median 142.3 vs. 120; p = 0.037) and lower hemoglobin levels (10.5 vs. 11.40; p = 0.004) compared to older patients. Spleen size was significantly larger in AYAs (18.8 vs. 15.5; p = 0.001). While AYAs showed better prognostic scores by Sokal and Hasford criteria, EUTOS and ELTS scores indicated comparable risk stratification. However, AYAs exhibited lower rates of MMR (56.7% vs. 73.4%; p = 0.016) and achieved MMR at a slower pace (median time 130 vs. 103 months; p = 0.064). Similarly, the percentage of DMR was lower in AYAs (37.1% vs. 46.8%; p = 0.175). CONCLUSION: Despite their younger age, AYAs with CML displayed poorer prognoses compared to older patients. These findings underscore the importance of tailored management strategies for AYAs with CML to optimize outcomes in this distinct patient population.

Optical coherence tomography-guided vs. intravascular ultrasound-guided percutaneous coronary intervention: a systematic review and meta-analysis of randomized controlled trials.

Background: Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) are superior to coronary angiography for guiding percutaneous coronary intervention (PCI). However, whether one technique is superior to the other is inconclusive. Methods: We searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov from inception to November 2023 for randomized controlled trials (RCTs) comparing OCT and IVUS in patients undergoing PCI. RevMan 5.4 was used to pool outcomes with risk ratio (RR) as the effect measure. Results: Six RCTs (4,402 patients) were included in this meta-analysis. There was no significant difference between the OCT- and IVUS-guided PCI groups in the risk of major adverse cardiovascular events (RR 0.87, 95% CI: 0.65, 1.16; I2 = 0%) and cardiac mortality (RR 0.73, 95% CI: 0.24, 2.21; I2 = 0%). The results were consistent across the subgroups of the presence or absence of left main disease (P interaction >0.1). There were no significant differences between OCT and IVUS in the risk of target lesion revascularization (RR 0.78, 95% CI: 0.47, 1.30; I2 = 0%), target vessel revascularization (RR 1.06, 95% CI: 0.69, 1.62; I2 = 0%), target-vessel myocardial infarction (RR 0.79, 95% CI: 0.40, 1.53; I2 = 0%), stent thrombosis (RR 0.59, 95% CI: 0.12, 2.97; I2 = 0%), and all-cause mortality (RR 1.01, 95% CI: 0.53, 1.90; I2 = 0%). Conclusions: Our meta-analysis demonstrated similar clinical outcomes in OCT- and IVUS-guided PCI. New large-scale multicenter RCTs with long-term follow-up are required to confirm or refute our findings and provide more reliable results. Systematic Review Registration: PROSPERO, identifier, CRD42023486933.

Prognostic role of suPAR in acute pancreatitis: A protocol for systematic review.

BACKGROUND: Acute pancreatitis (AP) is a common emergency condition with high morbidity, mortality, and socio-economic impact. Soluble urokinase plasminogen activator receptor (suPAR) is a potential biomarker for AP prognosis. This study systematically reviews the literature on suPAR's prognostic roles in assessing AP severity, organ failure, mortality, and other pathological markers. METHODS: A comprehensive search of 5 databases up to March 19, 2023, was conducted, selecting cohort studies that examined suPAR's relationship with AP outcomes. Outcome variables included AP severity, organ failure, mortality, hospital stay length, and suPAR's association with other inflammatory markers. Our paper has been registered on Prospero (ID: CRD42023410628). RESULTS: Nine prospective observational studies with 1033 AP patients were included. Seven of eight studies found suPAR significantly elevated in severe acute pancreatitis (P < .05). Four studies showed suPAR effectively predicted organ failure risk, and 4 studies concluded suPAR significantly predicted mortality (P < .05). The review had no high-risk studies, enhancing credibility. CONCLUSION: suPAR is a valuable prognostic marker in AP, significantly predicting severity, organ failure, hospital stay length, and mortality. Further large-scale studies are needed to explore suPAR's role in other clinical outcomes related to AP disease course, to establish it as a mainstay of AP prognosis.

Revolutionizing disease diagnosis and management: Open-access magnetic resonance imaging datasets a challenge for artificial intelligence driven liver iron quantification.

Artificial intelligence (AI), particularly machine learning (ML) and deep learning (DL) techniques, such as convolutional neural networks (CNNs), have emerged as transformative technologies with vast potential in healthcare. Body iron load is usually assessed using slightly invasive blood tests (serum ferritin, serum iron, and serum transferrin). Serum ferritin is widely used to assess body iron and drive medical management; however, it is an acute phase reactant protein offering wrong interpretation in the setting of inflammation and distressed patients. Magnetic resonance imaging is a non-invasive technique that can be used to assess liver iron. The ML and DL algorithms can be used to enhance the detection of minor changes. However, a lack of open-access datasets may delay the advancement of medical research in this field. In this letter, we highlight the importance of standardized datasets for advancing AI and CNNs in medical imaging. Despite the current limitations, embracing AI and CNNs holds promise in revolutionizing disease diagnosis and treatment.

Metabolic dynamics in chronic gastritis: Examining urinary profiles post Helicobacter pylori eradication.

Chronic gastritis is the persistent and insidious inflammation of the gastric lining. Helicobacter pylori (H. pylori) has been identified as the most common cause of chronic gastritis and consequently elimination of H. pylori can lead to its cure. This editorial explores the use of urinary metabolic profiles before and after eradication to identify biomarkers that can aid in prognosis and treatment. Despite providing promising insights, there are limitations such as a small sample size (17 patients), a narrow treatment period of 2 wk, and treatment heterogeneity, which raise concerns. Nevertheless, these findings have opened a gateway to enhancing the treatment and prognosis of chronic gastritis through urinary metabolomics.

Using primary healthcare facilities and patients' expectations about triage system: Patients' perspective from multisite Jordanian hospitals.

BACKGROUND: Using primary healthcare facilities can decrease the tension and workload in emergency departments (EDs). This study aim to examine the patient's use of primary healthcare facilities before EDs visits and their expectations about the triage. METHODS: A cross-sectional design was utilized in at various EDs in different hospitals. A convenience sample of 726 patients were enrolled and completed a self-administrated questionnaire. RESULTS: The mean age of the participants was 38.1 (SD = 12.9). Most participants (68.2 %) did not have primary care physicians and did not want to know how long other patients waited (61.4 %). There are significant relationships between participants' desired to know how long other patients have been waiting and their age (X2 = 4.02, P < .05), education level (X2 = 13.5, P < .001), and current job (X2 = 9.90, p < .05). Also, periodic updates from EDs staff about the delays were significantly related to participants' age (X2 = 3.29), current job (X2 = 28.4), marital status (X2 = 8.93), and residency place (X2 = 9.94). CONCLUSION: Educating patients about the triage system and the importance of using primary healthcare facilities is recommended to reduce ED waiting times and overload.

Autism Spectrum Disorder in a Single Family: A Case Series of Three Siblings.

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with a rising prevalence worldwide. While genetic factors are significantly associated with the disorder, environmental factors are often speculated to contribute to its onset. The Middle East, exhibiting higher rates of ASD, also sees frequent consanguineous marriages, necessitating focused studies on potential etiological factors in the region. We report a unique case of a family with three children diagnosed with ASD. The parents, aged between 35 and 39 years at the birth of their first child, have no notable familial history of neurodevelopmental disorders. Interestingly, while both parents and two of the children had normal chromosomal patterns, one child displayed chromosomal abnormalities. This discrepancy raises questions about the interplay between genetics and external factors in the manifestation of ASD. The family's medical history, combined with the regional context of high ASD prevalence and consanguineous marriages, provides a compelling backdrop for the study. The presence of chromosomal abnormalities in only one child, despite no detectable genetic irregularities in parents or siblings, underscores the potential influence of environmental factors in the development of ASD. This case accentuates the importance of conducting in-depth genetic and environmental studies to unravel the intricate etiological web surrounding ASD in the Middle East.

Bouveret's syndrome: A rare case of gallstone causing gastric outlet obstruction.

Key Clinical Message: The case highlights the importance of decisive action in addressing large gallstones causing gastric outlet obstruction. The chosen single-stage surgical approach reflects the need to manage both obstruction and the gallstone simultaneously. Abstract: Bouveret's syndrome is a rare cause of gastric outlet obstruction secondary to gallstones entering the enteric system through an acquired cholecystoduodenal fistula. Here, we present the case of an 85-year-old female who presented to our emergency department with gastric outlet obstruction secondary to a large gallstone in the third part of the duodenum. Abdominal X-ray did not demonstrate air-fluid levels but revealed a dilated gastric shadow, suggesting gastric outlet obstruction. EGD showed a dilated stomach and a hard, golf ball-sized gallstone in the duodenum. CT scan showed a distended stomach with a large gallstone obstructing the DJ junction and air in the biliary tree. Findings were suggestive of perforation of the gallbladder with stone impaction in the duodenojejunal (DJ) junction. The patient was managed surgically with a one-stage procedure comprising enterotomy, fistula closure, and cholecystectomy. Although Bouveret's syndrome is rare, it is important for practicing surgeons to have a high index of suspicion for this condition due to the high mortality associated with it.

Diagnosis and Management Approaches for Cerebellar Hydatid Cysts: A Systematic Review of Cases.

Cerebellar hydatid cysts are uncommon lesions, with limited cases reported in the literature. This systematic review aimed to summarize current diagnostic and management approaches, given the low suspicion index of hydatid cysts in the cerebellum. The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under registration number CRD42023437853. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-P) reporting guidelines. Two independent researchers searched PubMed, Scopus, and Google Scholar databases on June 27, 2023. We included 15 studies published between 1965 and 2022, comprising 12 case reports and three case series. A pooled analysis of reported cases (nine females and seven males) with cerebellar hydatid cysts revealed a mean age of 24 ± 20 years. Most of the cases were reported in Turkish hospitals (n = 8). The prominent signs and symptoms observed were headaches (10, 62.5%), ataxic gait (9, 56.25%), and visual disturbances (9, 56.25%). The time from symptom onset to hospital visit varied, with most patients seeking medical attention within the first three months. The left cerebellar hemisphere was the most common location of the cysts (6, 37.5%), and compression of the fourth ventricle was frequently observed. Computed tomography (CT) and magnetic resonance imaging (MRI) were the primary diagnostic tools used in three-fourths of cases, and surgical intervention was the primary treatment approach. Albendazole and praziquantel were commonly prescribed postoperatively, and two patients underwent preoperative needle decompression. This systematic review contributes to a better understanding of cerebellar hydatid cysts and guides future research and clinical management of this entity.

Stroke in Qatar: a decade of insights from a national registry.

BACKGROUND: Stroke is a major cause of death and disability worldwide and presents a significant burden on healthcare systems. This retrospective study aims to analyze the characteristics and outcomes of stroke patients admitted to Hamad General Hospital (HGH) stroke service in Qatar from January 2014 to July 2022. METHODS: The medical records of 15,859 patients admitted during the study period were analyzed. The data collected included patient demographics, stroke types, admission location, procedures performed, mortality rates, and other clinical characteristics. RESULTS: Of the total cohort, 70.9% were diagnosed with a stroke, and 29.1% were diagnosed with stroke mimics. Of the stroke patients, 85.3% had an ischemic stroke, and 14.7% had a hemorrhagic stroke. Male patients below 65 years old (80.2%) and of South Asian ethnicity (44.6%) were the most affected. The mortality rate was 4.6%, significantly higher for hemorrhagic stroke than ischemic stroke (12.6% vs. 3.2%). Female patients had a higher stroke-related mortality rate than male patients (6.8% vs. 4%). The thrombolysis rate was 9.5%, and the thrombectomy rate was 3.4% of the ischemic stroke cohort. The mean door-to-needle time for thrombolysis was 61.2 minutes, and the mean door-to-groin time for thrombectomy was 170 minutes. Stroke outcomes were good, with 59.3% of patients having favorable outcomes upon discharge (mRS ≤2), which improved to 68.2% 90 days after discharge. CONCLUSION: This study provides valuable insights into stroke characteristics and outcomes in Qatar. The findings suggest that stroke mortality rates are low, and favorable long-term disability outcomes are achievable. However, the study identified a higher stroke-related mortality rate among female patients and areas for improvement in thrombolysis and thrombectomy time.

Herpes simplex viral encephalitis with acute memory impairment and low cellular cerebrospinal fluid: A case report with systematic review literature.

Herpes simplex encephalitis (HSVE) is a potentially fatal infectious central nervous system (CNS) disorder. Thus, early detection is critical in determining the case's fate. Clinical history and examination, brain computed tomography, dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), and lumbar puncture have been used to establish a diagnosis. This report describes a case of HSVE with hypocellular cerebrospinal fluid (CSF) and an uncommon form of memory impairment. However, MRI results were consistent with HSVE, and CSF PCR tested positive for HSV-1 DNA that responded to treatment. We routinely advise patients to begin antiviral therapy as soon as possible to avoid complications.
