Complex left appendage morphology is associated with Embolic Stroke of Undetermined Source.

INTRODUCTION: Variations in the left atrial appendage (LAA) morphology are associated with different embolic risk in patients with atrial fibrillation (AF). Data are scarce regarding the association between LAA morphology and Embolic stroke of undetermined source (ESUS). PATIENTS AND METHODS: Using cardiac computed tomography (CCT) scans, LAA morphology was categorized as either chicken wing (CW), cactus, windsock, or cauliflower. Furthermore, we examined the presence of large secondary lobes arising from the main lobe, considering their existence as indicative of a complex LAA morphology. LAA morphologies were compared between ESUS (n = 134) and AF patients (n = 120); and between ESUS patients with (n = 24) and without (n = 110) subsequent AF diagnosis during long-term follow-up. RESULTS: ESUS patients had a significantly higher prevalence of cauliflower morphology compared to AF group (52% vs 34%, respectively, p = 0.01); however, no significant difference was found between the groups when categorizing LAA morphology to either CW or non-CW. ESUS patients had significantly higher prevalence of large secondary lobes compared with AF patients (50% vs 29%, respectively, p = 0.001). When comparing ESUS patients with and without AF diagnosis during follow-up (20-48 months of follow-up, median 31 months), there were no significant differences in the prevalence of the "classical" morphologies, but large secondary lobes were significantly more prevalent among those without subsequent AF diagnosis. CONCLUSION: ESUS patients have a high prevalence of complex LAA morphology, which might be associated with an increased risk for thrombus formation even in the absence of AF.

Prevalence and Mortality Rates of Acute Kidney Injury among Critically Ill Patients: A Retrospective Study.

Acute kidney injury (AKI) poses a significant challenge in critically ill patients. To determine the prevalence, risk factors, and mortality rate of AKI among nonsurgical critically ill patients in Jordan University Hospital, we conducted a retrospective study using a consecutive sampling method, including 457 nonsurgical critically ill patients admitted to the medical intensive care unit (MICU) from January to June 2021. The mean age was 63.8 ± 18 years, with 196 (42.8%) developing AKI during their stay in the MICU. Among AKI nonsurgical patients, pulmonary diseases (n = 52; 34.5%) emerged as the primary cause for admission, exhibiting the highest prevalence, followed by sepsis (n = 40; 20.4%). Furthermore, we found that older age (adjusted OR (AOR): 1.04; 95% confidence interval (CI): 1.04-1.06; p = 0.003), preadmission use of diuretics (AOR: 2.12; 95% CI: 1.06-4.25; p = 0.03), use of ventilators (2.19; 95% CI: 1.12-2.29; p = 0.02), and vasopressor use during MICU stay (AOR: 4.25; 95% CI: 2.1308.47; p = 0.001) were observed to have higher mortality rates. Prior utilization of statins before admission exhibited a significant association with reduced mortality rate (AOR: 0.42; 95% CI: 0.2-0.85; p = 0.02). Finally, AKI was associated with a higher mortality rate during MICU stay (AOR: 2.44; 95% CI: 1.07-5.56; p = 0.03). The prevalence of AKI among nonsurgical patients during MICU stay is higher than what has been reported previously in the literature, which highlights the nuanced importance of identifying more factors contributing to AKI in developing countries, and hence providing preventive measures and adhering to global strategies are recommended.

Relationship between tinnitus and headache in Riyadh, Saudi Arabia.

Objective: Our aim was to estimate prevalence rates of different headache forms among tinnitus patients in Arabia, to investigate whether there is a relationship between tinnitus laterality and headache laterality in patients with unilateral tinnitus and unilateral headache, to explore the relationship between tinnitus and headache over time, and to know the effect of headache pain medications in tinnitus in Riyadh, Saudi Arabia. Method: The study is a quantitative observational cross-sectional study with a convenient sample by data from patients with tinnitus. The participants received a self-administrated electronic questionnaire measuring demographics, prevalence of an associated headache, and the relationship between tinnitus and headache. Results: A total of 226 patients enrolled themselves into the study, and all of them came from the capital city Riyadh of Saudi Arabia. 58% were females, and the remainder of them were males. Females reported significantly more ear tinnitus than males, and patients aged 51 years or older were significantly less inclined to report ear tinnitus compared to those younger; however, those aged 20-31 years were found to be significantly more inclined to report ear tinnitus. There was a statistically significant association between patients experiencing headaches and those experiencing ear tinnitus. Surprisingly, patients who take medications of any type to alleviate their headaches were significantly less inclined to report ear tinnitus than those who do not take medications. However, patients with ear tinnitus experienced longer headache duration in years than those who had no history of tinnitus. Moreover, those people who experienced right-sided tinnitus tended to report significantly more right-sided headaches, and the same goes for left-sided headaches. Conclusion: Our results showed that there is a relationship between headaches and tinnitus. Painkillers also showed a protective effect against tinnitus. High awareness about the relationship between headaches and tinnitus among physicians and patients may lead to early recognition and lead to early implementation of primary prevention, which is the cornerstone of family medicine practice, and treatment without referring to other specialties. However, the pathophysiology is still not clear. Further studies should be performed to know the pathophysiology.

Improving awareness of kidney function through electronic urine output monitoring: a comparative study.

BACKGROUND: The current classification for acute kidney injury (AKI) according to the Kidney Disease: Improving Global Outcomes (KDIGO) criteria integrates both serum creatinine (SCr) and urine output (UO). Most reports on AKI claim to use KDIGO guidelines but fail to include the UO criterion. It has been shown that patients who had intensive UO monitoring, with or without AKI, had significantly less cumulative fluid volume and fluid overload, reduced vasopressor use, and improved 30-day mortality. We examined whether real-time monitoring of this simple, sensitive, and easy-to-use biomarker in the ICU led to more appropriate intervention by healthcare providers and better outcomes.  METHODS: RenalSense Clarity RMS Consoles were installed in the General ICU at the Hadassah Medical Center, Israel, from December 2019 to November 2020. The Clarity RMS system continuously and electronically monitors UO in real-time. 100 patients were randomly selected from this period as the study group (UOelec) and compared to a matched control group (UOmanual) from the same period two years earlier. To test whether there was an association between oliguric hours and fluid treatment in each group, the correlation was calculated and analyzed for each of the different UO monitoring methods. RESULTS: Therapeutic intervention: The correlation of the sum of all oliguric hours on Day 1 and 2 with the sum of any therapeutic intervention (fluid bolus or furosemide) showed a significant correlation for the study group UOelec (P = 0.017). The matched control group UOmanual showed no such correlation (P = 0.932). Length of Stay (LOS): Median LOS [IQR] in the ICU of UOelec versus UOmanual was 69.46 [44.7, 125.9] hours and 116.5 [62.46, 281.3] hours, respectively (P = 0.0002). CONCLUSIONS: The results of our study strongly suggest that ICU patients had more meaningful and better medical intervention, and improved outcomes, with electronic UO monitoring than with manual monitoring.

Seclusion: A Patient Perspective.

The appropriate treatment of mentally unwell, aggressive patients has challenged psychiatry for centuries. Seclusion is practiced worldwide, but concerns remain regarding its appropriateness and lack of alternatives. Patients generally report seclusion as a negative experience, though there is a paucity of literature exploring this in detail. This investigation was a service evaluation appraising inpatients' perspective of processes occurring before (information, communication), during (review, care), and after (debrief, reflection) seclusion in a psychiatric intensive care unit (PICU). In this phenomenological study, qualitative data were gathered using a questionnaire in a structured interview. All patients had been nursed in seclusion during admission to a male PICU at South London and the Maudsley NHS Foundation Trust. Ten patients were interviewed over 4 months. The central theme was perceived lack of communication in the patient-professional relationship, which manifested itself as (i) violence against patients, (ii) lack of psychological support, and (iii) the need for alternatives. Such feedback from patients queries whether national guidelines are appropriate and/or being adhered to. Healthcare practitioners have a responsibility to challenge accepted practice to continually improve the standard of patient-centred care. Utilising patient perspectives can be a powerful driver of change towards more humane treatment of vulnerable patients.

Adverse effects of phytoestrogens on reproductive health: a report of three cases.

BACKGROUND: Phytoestrogens have been thought to have favorable effects on women's health and perhaps in offsetting cancers. The possible adverse effects of phytoestrogens have not been evaluated. CASES: Abnormal uterine bleeding with endometrial pathology in three women was found to be related to a high intake of soy products. The first woman had postmenopausal bleeding with uterine polyp, proliferative endometrium and a growing leiomyoma. The second woman presented with severe dysmenorrhea, abnormal uterine bleeding, endometriosis and uterine leiomyoma not responding to treatment. The third woman with severe dysmenorrhea, abnormal uterine bleeding, endometriosis and uterine leiomyomata presented with secondary infertility. All three women improved after withdrawal of soy from their diet. CONCLUSION: Additional information on phytoestrogens is necessary to ascertain their safety before they can be routinely used as supplements.

Bisphosphonates and osteonecrosis of the jaw: a retrospective study.

OBJECTIVE: To assess the prevalence of osteonecrosis of the jaw (ONJ) in patients receiving bisphosphonate therapy and in those who were bisphosphonate naïve. METHODS: We undertook a retrospective review of medical records of patients at the New York Harbor Health Care System from 1999 through 2004. Charts were selected for review if patients had a Current Procedural Terminology (CPT) code suggestive of ONJ or if they had ever received bisphosphonate therapy. RESULTS: Among 1,951 medical records reviewed, we identified 2 patients with ONJ who had received bisphosphonates and 2 patients with ONJ who were bisphosphonate naïve. Both patients treated with bisphosphonates had multiple myeloma and were receiving monthly infusions. They had initially received pamidronate before treatment was changed to zoledronic acid. In each case, ONJ was precipitated by a routine dental extraction. The prevalence of ONJ in our patient population receiving intravenously administered bisphosphonates was 1 in 71.5. Of the 2 cases of ONJ in bisphosphonate-naïve patients, osteoradionecrosis was clearly incriminated in 1 patient and potentially the causative factor in the other patient as well. No patients receiving orally administered bisphosphonates had ONJ, nor did this complication occur in any patients receiving parenteral bisphosphonate therapy for disorders such as osteoporosis or Paget's disease of bone. CONCLUSION: Bisphosphonates remain an important option for management of metabolic bone disease and complications of malignant disease. The overall prevalence of ONJ in patients receiving bisphosphonates seems to be very low; however, patients receiving intense parenteral therapy for an underlying malignant condition appear to have a uniquely elevated risk for the development of this complication. A causal relationship between bisphosphonates and ONJ remains to be proved and merits further investigation.
