This study aims to explore how artificial intelligence can help ease the burden on caregivers, filling a gap in current research and healthcare practices due to the growing challenge of an aging population and increased reliance on informal caregivers. We conducted a search with Google Scholar, PubMed, Scopus, IEEE Xplore, and Web of Science, focusing on AI and caregiving. Our inclusion criteria were studies where AI supports informal caregivers, excluding those solely for data collection. Adhering to PRISMA 2020 guidelines, we eliminated duplicates and screened for relevance. From 947 initially identified articles, 10 met our criteria, focusing on AI’s role in aiding informal caregivers. These studies, conducted between 2012 and 2023, were globally distributed, with 80% employing machine learning. Validation methods varied, with Hold-Out being the most frequent. Metrics across studies revealed accuracies ranging from 71.60% to 99.33%. Specific methods, like SCUT in conjunction with NNs and LibSVM, showcased accuracy between 93.42% and 95.36% as well as F-measures spanning 93.30% to 95.41%. AUC values indicated model performance variability, ranging from 0.50 to 0.85 in select models. Our review highlights AI’s role in aiding informal caregivers, showing promising results despite different approaches. AI tools provide smart, adaptive support, improving caregivers’ effectiveness and well-being.

Anticoagulants - therapeutic use
2016
Cardiovascular disease (CVD) is a systemic process involving multiple vascular beds and includes coronary heart disease (CHD), ischemic cerebrovascular disease (ICVD), and peripheral arterial disease (PAD). All these manifestations are associated with an increased risk of subsequent myocardial infarction, stroke, and death. Guideline-directed medical therapy is recommended for all patients with CVD. In a cohort of US veterans, we identified 1,242,015 patients with CVD receiving care in 130 Veterans Affairs facilities from October 1, 2013 to September 30, 2014. CVD included diagnoses of CHD, PAD, or ICVD. We assessed the frequency of risk factor optimization and the use of guideline-directed medical therapy in patients with CHD, PAD alone, ICVD alone, and PAD + ICVD groups. A composite of 4 measures (blood pressure <140/90 mm Hg, A1c <7% in diabetics, statin use, and antiplatelet use in eligible patients), termed optimal medical therapy (OMT) was compared among groups. Multivariate logistic regression was performed with CHD as the referent category. CHD comprised 989,380 (79.7%), PAD alone 70,404 (5.7%), ICVD alone 163,730 (13.2%), and PAD + ICVD 18,501 (1.5%) of the cohort. Overall, only 36% received OMT with adjusted odds ratios of 0.54 (95% CI 0.53 to 0.55), 0.77 (0.76 to 0.78), and 0.97 (0.94 to 1.00) for patients with PAD alone, ICVD alone, and PAD + ICVD, respectively, compared with patients with CHD. In conclusion, OMT was low in all groups. Patients with PAD alone and ICVD alone were less likely to receive OMT than those with CHD and PAD + ICVD.

Nimodipine, an L-type cerebroselective calcium channel antagonist, is the only drug approved by the US Food and Drug Administration for the neuroprotection of patients with aneurysmal subarachnoid hemorrhage (aSAH). Four randomized, placebo-controlled trials of nimodipine demonstrated clinical improvement over placebo; however, these occurred before precision medicine with pharmacogenomics was readily available. The standard enteral dose of nimodipine recommended after aSAH is 60 mg every 4 h. However, up to 78% of patients with aSAH develop systemic arterial hypotension after taking the drug at the recommended dose, which could theoretically limit its neuroprotective role and worsen cerebral perfusion pressure and cerebral blood flow, particularly when concomitant vasospasm is present. We investigated the association between nimodipine dose changes and clinical outcomes in a consecutive series of 150 patients (mean age, 56 years; 70.7% women) with acute aSAH. We describe the pharmacogenomic relationship of nimodipine dose reduction with clinical outcomes. These results have major implications for future individualized dosing of nimodipine in the era of precision medicine.

Process Assessment (Health Care)
2016
In 2011, our institution developed a venous thromboembolism (VTE) prophylaxis order set to monitor prophylaxis management through physician-generated risk assessment orders. Prophylaxis rates obtained using the risk assessment orders were falsely low compared with chart review. Our goal was to redesign the order set to increase the percentage of VTE risk assessments ordered, both to improve care and to better reflect performance.

Veterans Health Administration.
Patients admitted to acute care and intensive care medical units.
Process analysis was used to identify systems failures limiting use of the original order set. The order set was redesigned using a human factors approach.
VTE risk assessment orders.
The order set was redesigned to reduce complexity and improve integration into provider workflow. The rate of risk assessment orders placed within 24 h increased from 48.6 to 80.4% (P < 0.001). There was no difference in the actual use of prophylaxis. However, for patients on prophylaxis, the rates of having a documented 'moderate' or 'high' risk assessment within 24 h increased from 66.7 to 95.7% (P < 0.001).
Using human factor principles to redesign an order set led to a significant increase in the percentage of patients with a risk assessment order placed within 24 h of admission. Although the risk assessments using the redesigned order set better reflected physician performance, it remained an imperfect measure for VTE prophylaxis. New technology used to measure human performance must be evaluated following implementation to assess accuracy.

Angiotensin-Converting Enzyme Inhibitors - therapeutic use
2012
Hypertension is a common disorder linked to increases in cardiovascular mortality and morbidity. Effective treatment decreases this excess mortality. Therapy with a single antihypertensive agent fails to achieve blood pressure goals in up to 75 % of patients. Compared to monotherapy, combination antihypertensive therapy, especially with fixed-dose (single pill) formulations, may more effectively control blood pressure and improve medication persistence while decreasing adverse effects, healthcare costs, and physician therapeutic inertia. Certain combinations, such as a calcium channel blocker and angiotensin converting enzyme inhibitor, have been associated with similar or fewer adverse effects and better outcomes than other combinations. In contrast, other combinations such as thiazide diuretics and β-blockers may cause more adverse effects than monotherapy. When choosing a thiazide diuretic, chlorthalidone is preferable to hydrochlorothiazide, given better efficacy and cardiovascular outcomes. Initial combination antihypertensive therapy may benefit patients with stage I or II hypertension and more widespread use should be encouraged.

On examination, temperature was 39.1°C, and heart rate was 109 beats per minute with normal blood pressure. Risk factors include immunocompromised state, diabetes and cirrhosis.1 Infection may be contracted by consuming undercooked seafood or swimming in contaminated sea water.2 Acute tonsillitis caused by V. vulnificus is rare, with no reported cases in the literature. V. vulnificus is usually susceptible to tetracyclines alone, but adding a cephalosporin is associated with better therapeutic response.3 Learning points V.vulnificus tonsillitis is rare and can lead to septicaemia in susceptible patients.

Abstract
Diffuse alveolar hemorrhage (DAH) is a rare, but potentially fatal, complication of antiphospholipid syndrome, and may present with acute and fulminant symptoms. We report a case of DAH presenting as sudden onset dyspnea in a gentleman with known antiphospholipid syndrome. Chest computed tomography angiography with pulmonary embolism protocol showed right lower lobe segmental filling defects, upper-lobe predominant diffuse ground-glass opacities, and centrilobular nodules bilaterally. The presence of DAH can be confirmed by bronchoalveolar lavage with serial aliquots, but this procedure typically does not elucidate the specific etiology for the hemorrhage. The treatment for patients with severe disease typically consists of a combination of immunosuppressive medications in the form of high-dose intravenous glucocorticoids plus rituximab, cyclophosphamide or mycophenolate; and/or plasma exchange. This case both provides an example of high-quality diagnostic imaging of diffuse alveolar hemorrhage as well as demonstrates the clinical and image-based improvement after treatment.

Use of Novel Strategies to Develop Guidelines for Management of Pyogenic Osteomyelitis in Adults
2022
Traditional approaches to practice guidelines frequently result in dissociation between strength of recommendation and quality of evidence.
To construct a clinical guideline for pyogenic osteomyelitis management, with a new standard of evidence to resolve the gap between strength of recommendation and quality of evidence, through the use of a novel open access approach utilizing social media tools.
This consensus statement and systematic review study used a novel approach from the WikiGuidelines Group, an open access collaborative research project, to construct clinical guidelines for pyogenic osteomyelitis. In June 2021 and February 2022, authors recruited via social media conducted multiple PubMed literature searches, including all years and languages, regarding osteomyelitis management; criteria for article quality and inclusion were specified in the group's charter. The GRADE system for evaluating evidence was not used based on previously published concerns regarding the potential dissociation between strength of recommendation and quality of evidence. Instead, the charter required that clear recommendations be made only when reproducible, prospective, controlled studies provided hypothesis-confirming evidence. In the absence of such data, clinical reviews were drafted to discuss pros and cons of care choices. Both clear recommendations and clinical reviews were planned with the intention to be regularly updated as new data become available.
Sixty-three participants with diverse expertise from 8 countries developed the group's charter and its first guideline on pyogenic osteomyelitis. These participants included both nonacademic and academic physicians and pharmacists specializing in general internal medicine or hospital medicine, infectious diseases, orthopedic surgery, pharmacology, and medical microbiology. Of the 7 questions addressed in the guideline, 2 clear recommendations were offered for the use of oral antibiotic therapy and the duration of therapy. In addition, 5 clinical reviews were authored addressing diagnosis, approaches to osteomyelitis underlying a pressure ulcer, timing for the administration of empirical therapy, specific antimicrobial options (including empirical regimens, use of antimicrobials targeting resistant pathogens, the role of bone penetration, and the use of rifampin as adjunctive therapy), and the role of biomarkers and imaging to assess responses to therapy.
The WikiGuidelines approach offers a novel methodology for clinical guideline development that precludes recommendations based on low-quality data or opinion. The primary limitation is the need for more rigorous clinical investigations, enabling additional clear recommendations for clinical questions currently unresolved by high-quality data.
