ABSTRACT

INTRODUCTION: The diagnosis of acute myocardial infarction is based on ECG abnormalities besides to chest pain and dyspnea. It is caused by myocardial hypoperfusion, in most patients due to severe coronary artery narrowing or occlusion, but it can also occur without visible coronary artery changes. The non-ST-elevation form (NSTEMI) is usually associated with less complaints compared to the ST-elevation form (STEMI), the ECG changes are not so typical, so its recognition is more difficult in the early stage. Possibility of myocardial cell damage reduction is the restoration of perfusion with coronary intervention.

OBJECTIVE: To investigate how much time elapses in acute NSTEMI from the onset of the complaint to the opening of the coronary vasodilator balloon.

METHOD: From 3733 acute coronary interventions performed in NSTEMI between 01. 01. 2016 and 12. 31. 2020, in 1376 patients who underwent percutaneous intervention for the first time, the onset of the complaints, the date of the first medical contact and opening of the balloon, as well as the 30-day or 1-year mortality were known. The median values of the time differences and the mortality data were compared with the similar data of 1718 STEMI patients of this period. The median times were given in hours:minutes, incidence in percent, a two-sample t-test was calculated for the comparison of mortality data.

RESULTS: In NSTEMI, the median time between the first medical contact (5:35 vs. 2:05 h:min) and PTCA balloon opening (18:12 vs. 4:05 h:min) was longer compared to the onset of the complaint as in STEMI. Within 2 hours, 21.3% of NSTEMI patients reached the first medical contact and 1.2% had the PTCA balloon opened, in STEMI this ratios were 48.7% and 11.7%. Within 4 hours, these were in NSTEMI 36.3% and 6.1%, in STEMI 64.1% and 46.8%. The 30-day mortality rate in NSTEMI was lower than in STEMI (5.9% vs. 7.9%, p = 0.03), the 1-year rate was higher (16.1% vs. 12.5%, p = 0.004). In 554 primarily admitted patients who met the study criteria, the median P-B time intervals were shorter (10:55 h:min), the mortality data showed a mild but statistically insignificant difference (5.6% at 30 days, 13.9% at 1 year).

CONCLUSION: Based on the 1-year mortality data, NSTEMI cannot be considered less harmful compared to STEMI. After the onset of hypoperfusion, myocardium necrosis proportional to the elapsed time increases the likelihood of subsequent heart failure. For this reason, it seems advisable for patients to reach the intervention center earlier than at present due to the invasive diagnostic and therapeutic options. Orv Hetil. 2023; 164(47): 1865-1870.

ABSTRACT

The aim of this study was to determine the cost-effectiveness of remote patient monitoring (RPM) with First Nations peoples living with diabetes. This study was set at the Goondir Health Service (GHS), an Aboriginal and Torres Strait Islander Community-Controlled Health in South-West Queensland. Electronic medical records and RPM data were provided by the GHS. Clinical effectiveness was determined by comparing mean HbA1c before and after enrolment in the RPM service. Our analysis found no statistically significant effect between the mean HbA1c before and after enrolment, so this analysis focused on net-benefit and return on investment for costs from the perspective of the GHS. The 6-month RPM service for 84 clients cost AUD $67,841 to cover RPM equipment, ongoing technology costs, and a dedicated Virtual Care Manager, equating to $808 per client. There were 199 additional client-clinician interactions in the period after enrolment resulting in an additional $4797 revenue for the GHS. Therefore, the program cost the GHS $63,044 to deliver, representing a return on investment of around 7 cents for every dollar they spent. Whilst the diabetes RPM service was equally effective as usual care and resulted in increased interactions with clients, the cost for the service was substantially more than the additional revenue generated from increased interactions. This evidence highlights the need for alternative funding models for RPM services and demonstrates the need to focus future research on long-term clinical effects and the extra-clinical benefits resulting from services of this type.

ABSTRACT

BACKGROUND: The success of assisted pregnancy relies heavily on the effectiveness of the embryo transfer process. Currently, embryo transfer is typically conducted with the assistance of abdominal ultrasound.

OBJECTIVE: The primary aim of this study was to evaluate the influence of targeted nursing interventions on the embryo transfer procedure, its impact on pregnancy outcomes, and the level of patient comfort concerning bladder management throughout the procedure.

METHODS: A total of 247 patients who underwent embryo transfer at the Reproductive Center of Peking University People’s Hospital from December 2019 to August 2020 were included in this study. These patients were categorized into two groups: the control group (n= 124) and the experimental group (n= 123). Within the control group, patients received conventional preoperative education, whereas those within the experimental group were subjected to targeted nursing interventions. Furthermore, patients in the experimental group were furnished with explicit instructions pertaining to the volume and timing of water intake. Multiple factors were assessed in this study, encompassing bladder filling, the quality of uterine imaging, the utilization of assistive devices during the surgical procedure, and pregnancy outcomes. Additionally, a post-operative questionnaire was administered to both groups to gauge their comfort levels regarding urinary retention.

RESULTS: Following the targeted nursing intervention, ultrasound scans indicated an increase in bladder depth (5.91 ± 1.76 vs. 5.40 ± 1.61, P= 0.02), resulting in clearer endometrial imaging (96.74% vs. 88.71%, P= 0.02). Additionally, the experimental group reported significantly higher levels of comfort with urine retention (P= 0.01) compared to the control group, and these differences held statistical significance. Furthermore, the pregnancy rate in the experimental group was greater than that in the control group (52.85% vs. 50.8%, P> 0.05).

CONCLUSION: Based on the premise that pregnancy rates remain unaffected, the implementation of targeted nursing care has the potential to augment bladder filling, enhance the quality of endometrial imaging, reduce the requirement for instrument-assisted embryo transfers, and notably enhance the comfort of patients in relation to urine retention.

ABSTRACT

PURPOSE: Over a 10-year time frame, this study aimed to evaluate diagnosis, treatment, and referral trends for adolescent runners seeking care for running-related injuries (RRIs) at a clinic that specializes in running medicine.

METHODS: This study was a retrospective chart review of 392 adolescent runners (2,326 encounters) who sought care for RRIs between the years 2011 and 2021. Descriptive statistics were used to summarize clinical assessments, referrals, assistive devices, and medications prescribed or administered overall and by injury type. Chi-square analyses were used to compare proportions of services rendered across the 10-year time frame.

RESULTS: Patients most frequently received manual evaluations or special tests during clinic visits. Most visits resulted in at least one referral (91%), primarily for physical therapy or gait-training. Assistive devices and medications/supplements were offered at only 18% of patient visits. The majority of assessments (X2 = 69.7, p = 0.002), treatments (X2: 23.6-43.8, p: < 0.001-0.003), and referrals (X2 = 132, p < 0.001) were for shin injuries. Larger proportions of nutrition assessments (X2 = 40.7, p < 0.001), interventions (X2 = 26.8, p = 0.003), and referrals (X2 = 27.5, p = 0.002) were performed in or after the year 2015.

CONCLUSION: Clinic visits for shin injuries required the most clinical resources per episode of care. There were observed shifts in clinical assessment and treatment approaches to include more expanded nutritional and physiologic considerations.

ABSTRACT

BACKGROUND: Timely communication is essential in attaining maternal satisfaction, developing an excellent physician-patient rapport, and increasing trust. This study reports a significant improvement in maternal communication rates through the quality improvement method.

METHODS: An educational module was developed, and NICU staff was presented with the slides, followed by a performance questionnaire to demonstrate understanding. The first phase was completed by obtaining feedback from mothers through a questionnaire. The first plan-do-study-act (PDSA) cycle, carried out for eight weeks looking at the rates of the maternal update provided within an hour of admission of their neonates to the NICU, was followed by the second PDSA cycle, carried out for ten weeks. The improvement was calculated using conventional statistics and a statistical process control chart.

RESULTS: During the first phase of the study, thirty-six percent of the mothers were updated within an hour of admission of their neonates to the NICU. During the first PDSA cycle, we did not notice a special cause variation or process change. A significant shift, eight consecutive points above the mean, was noted on the control chart during PDSA cycle 2. The mean±SD of the weekly update rate increased significantly during PDSA cycle 2 (76.8±11) compared to PDSA cycle 1 (47.5±14), p-value = 0.0002.

CONCLUSION: We improved the maternal update rates through the educational module following the QI improvement model using the PDSA cycles.

ABSTRACT

BACKGROUND: Alzheimer’s disease (AD) is a debilitating condition that is widely known to adversely affect gray matter (GM) and white matter (WM) tracts within the brain. Recently, precision medicine has shown promise in alleviating the clinical and gross morphological trajectories of patients with AD. However, regional morphological changes have not yet been adequately characterized.

OBJECTIVE: Investigate regional morphological responses to a precision medicine-guided intervention with regards to white and gray matter in AD and mild cognitive impairment (MCI).

METHODS: Clinical and neuroimaging data were compiled over a 9-month period from 25 individuals who were diagnosed with AD or MCI receiving individualized treatment plans. Structural T1-weighted MRI scans underwent segmentation and volumetric quantifications via Neuroreader. Longitudinal changes were calculated via annualized percent change of WM or GM ratios.

RESULTS: Montreal Cognitive Assessment scores (p < 0.001) and various domains of the Computerized Neurocognitive Screening Vital Signs significantly improved from baseline to 9-month follow-up. There was regional variability in WM and GM atrophy or hypertrophy, but none of these observed changes were statistically significant after correction for multiple comparisons.

ABSTRACT

BACKGROUND: Epidemiological studies showed that COVID-19 increases risk of Alzheimer’s disease (AD). However, it remains unknown if there is a potential genetic predispositional effect.

OBJECTIVE: To examine potential effects of genetic susceptibility of COVID-19 on the risk and progression of AD, we performed a non-overlapping 2-sample Mendelian randomization (MR) study using summary statistics from genome-wide association studies (GWAS).

METHODS: Two-sample Mendelian randomization (MR) analysis of over 2.6 million subjects was used to examine whether genetic susceptibility of COVID-19 is not associated with the risk of AD, cortical amyloid burden, hippocampal volume, or AD progression score. Additionally, a validation analysis was performed on a combined sample size of 536,190 participants.

RESULTS: We show that the AD risk was not associated with genetic susceptibility of COVID-19 risk (OR = 0.98, 95% CI 0.81-1.19) and COVID-19 severity (COVID-19 hospitalization: OR = 0.98, 95% CI 0.9-1.07, and critical COVID-19: OR = 0.98, 95% CI 0.92-1.03). Genetic predisposition to COVID-19 is not associated with AD progression as measured by hippocampal volume, cortical amyloid beta load, and AD progression score. These findings were replicated in a set of 536,190 participants. Consistent results were obtained across models based on different GWAS summary statistics, MR estimators and COVID-19 definitions.

CONCLUSIONS: Our findings indicated that the genetic susceptibility of COVID-19 is not associated with the risk and progression of AD.

ABSTRACT

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) are present in most people with dementia (PwD), including Alzheimer’s disease. There is consensus that non-pharmacological therapies represent the first line of treatment to address BPSD.

OBJECTIVE: We explore the efficacy of the use of a rocking chair (Nordic Sensi® Chair, NSC) in the treatment of BPSD in nursing home residents with moderate and severe dementia.

METHODS: We carried out a 16-week randomized, single-blind, controlled, clinical trial with PwD admitted to nursing homes. Participants were assigned to a treatment group (n = 40) that received three times a week one session per day of 20 minutes in the NSC and a control group (n = 37). The Neuropsychiatric Inventory-Nursing Home (NPI-NH) was used as primary efficacy outcome. Occupational distress for the staff was evaluated using the NPI-NH Occupational Disruptiveness subscale (NPI-NH-OD). Statistical analyses were conducted by means of a Mixed Effects Model Analysis.

RESULTS: Treatment with the NSC was associated with a beneficial effect in most of BPSD, as reflected by differences between the treatment and control group on the NPI-NH total score (mean change score -18.87±5.56 versus -1.74±0.67, p = 0.004), agitation (mean change score -2.32±2.02 versus -0.78±1.44, p = 0.003) and irritability (mean change score -3.35±2.93 versus -1.42±1.31, p = 0.004). The NPI-NH-OD total score also improved the most in the treatment group (mean change score -9.67±7.67 versus -7.66±6.08, p = 0.003).

CONCLUSIONS: The reduction in overall BPSD along with decreased caregiver occupational disruptiveness represent encouraging findings, adding to the potential of nonpharmacological interventions for nursing home residents living with dementia.

ABSTRACT

BACKGROUND: The Cogstate Brief Battery (CBB) is a computerized cognitive test battery used commonly to identify cognitive deficits related to Alzheimer’s disease (AD). However, AD and normative samples used to understand the sensitivity of the CBB to AD in the clinic have been limited, as have the outcome measures studied.

OBJECTIVE: This study investigated the sensitivity of CBB outcomes, including potential composite scores, to cognitive impairment in mild cognitive impairment (MCI) and dementia due to AD, in carefully selected samples.

METHODS: Samples consisted of 4,871 cognitively unimpaired adults and 184 adults who met clinical criteria for MCI (Clinical Dementia Rating (CDR) = 0.5) or dementia (CDR > 0.5) due to AD and CBB naive. Speed and accuracy measures from each test were examined, and theoretically- and statistically-derived composites were created. Sensitivity and specificity of classification of cognitive impairment were compared between outcomes.

RESULTS: Individual CBB measures of learning and working memory showed high discriminability for AD-related cognitive impairment for CDR 0.5 (AUCs ∼ 0.79-0.88), and CDR > 0.5 (AUCs ∼ 0.89-0.96) groups. Discrimination ability for theoretically derived CBB composite measures was high, particularly for the Learning and Working Memory (LWM) composite (CDR 0.5 AUC = 0.90, CDR > 0.5 AUC = 0.97). As expected, statistically optimized linear composite measures showed strong discrimination abilities albeit similar to the LWM composite.

CONCLUSIONS: In older adults, the CBB is effective for discriminating cognitive impairment due to MCI or AD-dementia from unimpaired cognition with the LWM composite providing the strongest sensitivity.

ABSTRACT

OBJECTIVE: To explore the discriminatory diagnostic value of multimodal ultrasound(US) combined with blood cell analysis(BCA) for Granulomatous Lobular Mastitis (GLM) and Invasive Ductal Carcinoma(IDC) of the breast.

METHODS: A total of 157 breast disease patients were collected and divided into two groups based on postoperative pathological results: the GLM group(57 cases with 57 lesions) and the IDC group(100 cases with 100 lesions). Differences in multimodal ultrasound features and the presence of BCA were compared between the two groups. The receiver operating characteristic(ROC) curve was used to calculate the optimal cutoff values, sensitivity, specificity, 95% confidence interval(CI), and the area under the curve(AUC) for patient age, lesion size, lesion resistive index(RI), and white blood cell(WBC) count in BCA. Sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy, and AUC were calculated for different diagnostic methods.

RESULTS: There were statistically significant differences(P < 0.05) observed between GIM and IDC patients in terms of age, breast pain, the factors in Conventional US(lesion size, RI, nipple delineation, solitary/multiple lesions, margin, liquefaction area, growth direction, microcalcifications, posterior echogenicity and abnormal axillary lymph nodes), the factors in CEUS(contrast agent enhancement intensity, enhancement pattern, enhancement range, and crab-like enhancement) and the factors in BCA(white blood cells, neutrophils, lymphocytes and monocytes). ROC curve analysis results showed that the optimal cutoff values for distinguishing GLM from IDC were 40.5 years for age, 7.15 cm for lesion size, 0.655 for lesion RI, and 10.525*109/L for white blood cells. The diagnostic accuracy of conventional US combined with CEUS(US-CEUS) was the highest(97.45%). The diagnostic performance AUCs for US-CEUS, CEUS, and US were 0.965, 0.921 and 0.832, respectively.

CONCLUSION: Multifactorial analysis of multimodal ultrasound features and BCA had high clinical application value in the differential diagnosis of GLM and IDC.
