ABSTRACT

BACKGROUND: The neuropathological confirmation serves as the gold standard for diagnosing Alzheimer’s disease (AD), but it is usually not available to the living individuals. In addition, the gold standard for diagnosing Mild Cognitive Impairment (MCI) remains unclear yet. Neuropsychological testing, such as the Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE) and Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-cog), is commonly used tests in identifying AD and MCI, offering convenience, affordability, non-invasiveness, and accessibility in clinical settings. We aimed to accurately evaluate the discriminative ability of the three tests administrated at the same visit simultaneously in detecting AD and MCI due to AD in the absence of a gold standard.

METHODS: A total of 1289 participants aged over 65 were included from the baseline visits of Alzheimer’s disease Neuroimaging Initiative. Bayesian latent class models, accounting for conditional dependence between MoCA and MMSE, were conducted to assess the diagnostic accuracy of the three tests for detecting AD and MCI.

RESULTS: In detecting AD, the ADAS-cog had the highest Youden’s Index (0.829), followed by the MoCA(0.813) and MMSE(0.796). The ADAS-cog and MoCA showed similar sensitivity (0.922 vs 0.912) and specificity (0.907 vs 0.901), while the MMSE had lower sensitivity (0.874) and higher specificity (0.922). For MCI detection, the ADAS-cog had the highest Youden’s Index (0.704) compared to the MoCA (0.614) and MMSE (0.478). The ADAS-cog exhibited the highest sensitivity, closely followed by the MoCA and MMSE (0.869 vs 0.845 vs 0.757), and the ADAS-cog also had good specificity (0.835 vs 0.769 vs 0.721). The estimated true prevalence of AD among individuals aged over 65 was 20.0%, and the estimated true prevalence of MCI due to AD was 24.8%.

CONCLUSIONS: The findings suggest that the ADAS-cog and MoCA are reliable tools for detecting AD and MCI, while the MMSE may be less sensitive in detecting these conditions. A large underdiagnosis of the MCI and Alzheimer’s population still remains in clinical screening.

ABSTRACT

BACKGROUND: The Community Paramedicine at Home (CP@home) program is a health promotion program where community paramedics conduct risk assessments with frequent 9-1-1 callers in their homes, with a goal of reducing the frequency of 9-1-1 calls in this vulnerable population. The effectiveness of the CP@home program was investigated through a community-based RCT conducted in four regions in Ontario, Canada. The purpose of this current recruitment study is to examine the challenges met when recruiting for a community randomized control trial on high frequency 9-1-1 callers.

METHODS: Eligible participants were recruited from one of four regions participating in the CP@home program and were randomly assigned to an intervention group (n = 1142) or control group (n = 1142). Data were collected during the recruitment process from the administrative database of the four paramedic services. Whether they live alone, their parental ethnicity, age, reason for calling 9-1-1, reason for not participating, contact method, and whether they were successfully contacted were recorded. Statistical significance was calculated using the Chi-Squared Test and Fisher’s Exact Test to evaluate the effectiveness of the recruitment methods used to enroll eligible participants in the CP@home Program.

RESULTS: Of the people who were contacted, 48.0% answered their phone when called and 53.9% answered their door when a home visit was attempted. In Total, 110 (33.1%) of people where a contact attempt was successful participated in the CP@home program. Most participants were over the age of 65, even though people as young as 18 were contacted. Older adults who called 9-1-1 for a lift assist were more likely to participate, compared to any other individual reason recorded, and were most often recruited through a home visit.

CONCLUSIONS: This recruitment analysis successfully describes the challenges experienced by researchers when recruiting frequent 9-1-1 callers, which are considered a hard-to-reach population. The differences in age, contact method, and reason for calling 9-1-1 amongst people contacted and participants should be considered when recruiting this population for future research.

ABSTRACT

BACKGROUND: In Kalhbaum’s first characterization of catatonia, the emotional symptoms, such as decreased or restricted expression of feelings and emotions, which is described as blunted affect, are related to the motor symptoms. In later years, the affective domain was excluded from the concept of catatonia and was not included among the diagnostic criteria in the various Diagnostic Statistical Manual (DSM) versions. In recent times, some authors have proposed the proposition of reevaluating the notion of catatonia through the reintroduction of the affective domain. The objective of this study was to examine the correlation between catatonic-like behavior (CLB), such as emotional withdrawal, blunted affect, and psychomotor slowing, and inflammatory markers, namely the neutrophil/lymphocytes ratio (NLR) and lymphocytes/monocytes ratio (LMR), in individuals diagnosed with schizophrenia.

METHOD: A sample of 25 patients with schizophrenia (10 females, 15 males) was recruited, and the Brief Psychiatric Rating Scale (BPRS) was used to assess the severity of emotional withdrawal, blunted affect, and psychomotor slowing.

FINDINGS: The correlation analysis (Spearman ρ) revealed a robust direct association between blunted affect and psychomotor slowing (ρ = 0.79, P = 0.001), and a significant direct correlation between CLB (emotional withdrawal, ρ = 0.51, P = 0.05; blunted affect ρ = 0.58, P = 0.05; motor retardation, ρ = 0.56, P = 0.05) and LMR (ρ = 0.53, P = 0.05). In addition, patients with a duration of illness (DOI) older than five years had a higher presence of CLB and a higher LMR than patients with a more recent diagnosis of the disease. Likely, patients with positive symptoms and in the prodromal and active stages of the disease have a different immune profile than patients in the residual stage and with a predominance of negative symptoms.

CONCLUSIONS: Psychomotor slowing and blunted affect are two significantly related features, representing the two-faced Janus of immobility. Furthermore, aggregating them in CLB is more predominant the longer the duration of schizophrenia and is associated with different a specific pattern of immune activation.

ABSTRACT

BACKGROUND: The aim of the scoping review was to identify and synthesize the available literature concerning the relationship between the status of refugees, migrants, and internally displaced persons (IDPs) and Early Childhood Caries (ECC) as it relates to the United Nation’s Sustainable Development Goal 16 (SDG 16).

METHODS: Data regarding the links between the status of refugees, migrants, and internally displaced persons (IDPs) and Early Childhood Caries (ECC), and the associations between ECC and maternal and child exposure to physical and sexual abuse, insecurity, crime, exploitation, torture, and displacement were extracted. The search was carried out in January 2023 across three databases (PubMed, Web of Science, and Scopus). Only publications in English with accessible full texts were included. Descriptive statistics were utilized to summarize the categories of the retrieved papers, and graphical representation was employed for visualization purposes. The relationships between the publications and each of the 10 targets of Sustainable Development Goal 16 (SDG 16) were also assessed.

RESULTS: Forty-five studies were reviewed. Most studies (42.2%) originated from the Americas Regions, while no studies were identified from the Africa Region. A significant portion (46.7%) of the papers focused on abuse, violence, and neglect as risk factors for ECC. Migrants, refugees, and IDPs were the most investigated populations (44.4%). Only one study specifically focused on IDPs and migrants respectively. The prevalence of untreated caries was higher among migrants, refugees, and IDPs compared to the host community, ECC was more prevalent among children who experienced abuse, neglect, or were in protective care. The was no clear direction on the associations between ECC and intimate partner violence, adverse childhood experiences, and wars. In terms of the SDGs, the reviewed publications addressed four targets (SDG16.1, SDG16.2, SDG16.3, and SDG16.5) out of the ten targets outlined in SDG 16.

CONCLUSION: There is available evidence regarding the connections between ECC and war, refugees, migration, violence, and neglect, as outlined in SDG 16. Future studies are needed to investigate how forced movements directly affects ECC status, how disruptions of peace and stability is a risk factor for ECC, and the associations between ECC and other indicators related to SDG 16 targets.

ABSTRACT

BACKGROUND: The variabilities in design and material of scan bodies have a major role in the positional transfer accuracy of implants. The purpose of this invitro study was to compare the 3D transfer accuracy (trueness and precision) of titanium base (TB) abutment position provided by 2 different scan bodies: one-piece scan body (SB) in comparison to two-piece healing abutment and scan peg (HA-SP).

METHODS: A maxillary model with a dummy implant in the 2nd premolar (Proactive Tapered Implant; Neoss) was 3D printed and TB (Ti Neolink Mono; Neoss) was tightened on the implant and scanned by using a laboratory scanner (inEos X5; Dentsply Sirona) (reference scan). An SB (Elos Medtech) and an HA-SP (Neoss) were subsequently connected to the implant and were scanned 10 times each by using the same scanner (test scans). All the scans were exported as STL files and imported into CAD software where the TBs were formed. Test scans were superimposed on reference scans for transfer accuracy analysis using 3D metrology software (GOM Inspect; GOM GmbH) in terms of angular deviation in vertical and horizontal directions, linear deviation in each XYZ axis of TBs and total linear deviation in all axes. Statistical analysis was done using independent sample t test. When Levene’s test for equality of variances was significant, Welch’s t-test was used. (P value < 0.05) RESULTS: Significant differences were found amongst the tested groups in both angular and linear deviation in terms of trueness with less deviation values for the SB group (P < 0.001). For the precision, significant differences were found amongst the tested groups in angular deviation in vertical direction with less deviation value for the SB group compared to HA-SP group (P < 0.001). However, no significant difference was found between the tested groups regarding the angular deviation in horizontal direction (P = 1.000). Moreover, significant differences were found amongst the tested groups in linear deviations with less linear deviations in XYZ axes for SB compared to HA-SP group (P = 0.020, < 0.001, = 0.010 respectively).

CONCLUSIONS: SB showed less angular and linear deviation values in the 3D positional transfer of TB than HA-SP indicating higher degree of accuracy of SB.

ABSTRACT

BACKGROUND: A meta-analysis has compared the pregnancy outcomes between women with and without RA, while the effect of disease severity on pregnancy outcomes within women with RA has not been explored. Therefore, we performed a systematic review and meta-analysis to assess the association between disease activity of RA and pregnancy outcomes.

METHODS: Four English databases (Pubmed, Embase, Cochrane Library, and Web of Science) and three Chinese databases (China National Knowledge Infrastructure [CNKI], VIP, and Wan Fang) was searched for eligible studies up to August 13, 2023. Cochran’s Q test and the I² statistic were used to assess the heterogeneity of the included studies. The odds ratio (OR) (for counting data) and weighted mean difference (WMD) (for measurement data) were calculated with 95% confidence intervals (95%CIs) using random-effect model (I² ≥ 50%) or fixed-effect model (I² < 50%). Subgroup analysis based on study design and regions was used to explore the sources of heterogeneity. Sensitivity analysis was performed for all outcomes and the publication bias was assessed using Begg’s test.

RESULTS: A total of 41 eligible articles were finally included. RA women had higher odds to suffer from preeclampsia, gestational diabetes, spontaneous abortion, and cesarean delivery (all P < 0.05). The infants born from RA mother showed the higher risk of stillbirth, SGA, LBW, congenital abnormalities, diabetes type 1, and asthma (all P < 0.05). The high disease activity of RA was significantly associated with the higher risk of cesarean delivery (OR: 2.29, 95%CI: 1.02-5.15) and premature delivery (OR: 5.61, 95%CI: 2.20-14.30).

CONCLUSIONS: High disease activity of RA was associated with the high risk of adverse pregnancy outcomes, suggesting that it was important to control disease for RA women with high disease activity who prepared for pregnancy.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the effect of secondhand smoke on dental caries and gingival health among schoolchildren in Damascus, Syria.

MATERIALS AND METHODS: This was a cross-sectional study. It was carried out at government schools in Damascus, Syria. This study included healthy children aged 10 to 13 years old. Schoolchildren were interviewed to answer the researcher-administered questionnaire to obtain answers regarding demographic information and family smoking behavior. A dental examination was performed by a dentist, and the number of decayed (D), missing (M), and filled (F) permanent teeth (DMFT) was scored based on the World Health Organization (WHO) 1997. A gingival examination was performed using the modified gingival index (MGI) and Silness-Leo plaque index (PI) to assess gingival inflammation and plaque accumulation, respectively.

RESULTS: A total of 284 schoolchildren participated. More than half (61.26%) of them were exposed to secondhand smoke (SHS), and about half of them (52.11%) resided in a house with at least one cigarette smoked in a day. About one-third of the passive smokers (33.30%) had poor plaque control, with a statistically significant difference from non-passive smokers (p < 0.05). The multivariate regression model showed that the number of smokers at home was significantly associated with the DMFT score, dental plaque accumulation, and gingival inflammation (p < 0.1). However, the number of cigarettes smoked at home in a day was not a predictor for dental caries and gingival status (p = 1.000).

CONCLUSIONS: Within the limitations of this study, the number of smokers at home appears to have more adverse effects on children’s oral health compared to the quantity of smoke inhaled. In addition, SHSe was associated with more dental plaque accumulation among schoolchildren.

ABSTRACT

Females demonstrate greater fatigue resistance during a range of exercise modalities; however, this may be confounded by the lower mechanical work completed. Accordingly, this study examined the sex-specific peripheral and central fatigue mechanisms during repeated all-out cycling and whether they are affected by total mechanical work performed. 26 healthy young adults (12 females) performed 10 × 10 s all-out cycling interspersed by 30 s passive recovery. Metabolic responses, peripheral and central fatigue was quantified via changes in pre- to post-exercise blood lactate, potentiated quadriceps twitch force (and contractile properties) evoked via supramaximal electrical stimulation of the femoral nerve, and voluntary activation of the knee extensors, respectively. During exercise, mechanical work, vastus lateralis muscle activation (via surface electromyography, EMG) and deoxygenation (via near-infrared spectroscopy) were recorded. Sex comparison analyses were performed before and after statistically controlling for total mechanical work (via ANCOVA). Mechanical work and muscle activation plateaued at similar sprint repetition (sprint 5) and voluntary activation change (pre vs. post) was similar between the sexes. Females, however, showed lower percent work decrement (i.e., fatigability; P = 0.037) and peripheral responses as evident by lower reductions in quadriceps twitch force (P < 0.001), and muscle deoxygenation (P = 0.001). Adjusting for total mechanical work did not change these sex comparison results. We show that females’ greater fatigue resistance during repeated all-out cycling may not be attributed to the greater total mechanical work performed but could be mediated by lower peripheral fatigue in the knee extensor muscles.

ABSTRACT

OBJECTIVE: Ophthalmia neonatorum (ON) is a conjunctivitis occurring in neonates and can be caused by multiple bacterial pathogens. The risk of invasive bacterial infection (IBI) in neonates with ON is poorly known. Our objectives were to document the association of ON with IBI in term neonates and to investigate practice variation.

METHODS: This was a retrospective observational study of all neonates who presented to a single emergency department (ED) between January 2018 and December 2019. Participants were all children with a final diagnosis of ON according to the treating physician as registered in the ED computerized database. Newborns with craniofacial malformations and premature infants were excluded. The primary outcome was IBI as defined by growth of any bacterial pathogen in the blood or cerebrospinal fluid. Perinatal risk factors, ED visit details (symptoms on presentation, management, and treatment plan) as well as complications (ocular morbidity, death, and unscheduled return visits) were collected. Data were analyzed using descriptive statistics.

RESULTS: Fifty-two term neonates were included. There were no cases of IBI associated with ON (0%; 95% confidence interval [CI], 0%-6.9%). Six ocular bacterial infections were identified, one of which was Chlamydia trachomatis. Although there were no IBIs, ocular complications, deaths, or unscheduled return visits to the ED, there was a wide variation in physician’s management of ON. Physicians ordered investigations in 49% (95% CI, 34%-62%) of neonates, prescribed antibiotics to 87% (95% CI, 74%-94%), and involved specialists in 39% (95% CI, 27%-52%) of cases.

CONCLUSIONS: Emergency department presentations of term neonates with ON are associated with a low risk of IBI. A better understanding of the current practice variation is needed to inform clinical guidelines for the management of neonates with ON presenting to the ED.
