Antidepressant-like effects of geniposide in chronic unpredictable mild stress-induced mice by regulating the circ_0008405/miR-25-3p/Gata2 and Oip5os1/miR-25-3p/Gata2 networks.

Evidence exists suggesting the anti-depressive activities of geniposide (GP), a major compound in Gardenia jasminoides Ellis. Accordingly, the present study attempts to explore the anti-depressive mechanism of GP in chronic unpredictable mild stress (CUMS)-induced depression-like behaviors of mice. CUMS-induced mice were given GP daily and subjected to behavioral tests to observe the effect of GP on the depression-like behaviors. It was noted that GP administration reduced depression-like behaviors in CUMS mice. Transcriptome sequencing was conducted in three control and three CUMS mice. Differentially expressed circRNAs, lncRNAs and mRNAs were then screened by bioinformatics analyses. Intersection analysis of the transcriptome sequencing results with the bioinformatics analysis results was followed to identify the candidate targets. We found that Gata2 alleviated depression-like behaviors via the metabolism- and synapse-related pathways. Gata2 was a target of miR-25-3p, which had binding sites to circ_0008405 and Oip5os1. circ_0008405 and Oip5os1 competitively bound to miR-25-3p to release the expression of Gata2. GP administration ameliorated depression-like behaviors in CUMS mice through regulation of the circ_0008405/miR-25-3p/Gata2 and Oip5os1/miR-25-3p/Gata2 crosstalk networks. Taken together, GP may exert a potential antidepressant-like effect on CUMS mice, which is ascribed to regulation of the circ_0008405/miR-25-3p/Gata2 and Oip5os1/miR-25-3p/Gata2 crosstalk networks.

Psychological Distress and Negative Emotions in Post-COVID Infection: A Comparative Study of the COVID and NO-COVID Young Patients.

According to the literature, mental health assumed urgent relevance, and several scholars are debating on the enduring of the neurological and psychiatric symptoms in post COVID patients. Our study aimed to investigate the emotional dimensions in young population to the COVID exposition: primary endpoint was to detect the psychological distress up to 3 months in post-COVID-19. A comparative study was conducted among young adults in Italy. We also assessed dysphoria, depression, anxiety, stress symptoms, pessimism, and positive personality traits. The participants were 140 Italian young aged 18-30 years (mean = 22.1, SD ± 2.65; 65.0% female). The sample was distinguished in two groups: COVID and NO-COVID groups. The results revealed that young who have been exposed to COVID-19 infection evidenced emotional vulnerability by higher psychological distress (depression, anxiety, stress), dysphoria signs (irritability, discontent, interpersonal resentment, and feelings of renunciation/surrender) then No COVID-19 infection young. Furthermore, COVID patients showed higher negative emotions about the expected life, uncertain for future, and loss of motivation (characterized no desires) than NO-COVID infection. In conclusion, the vulnerability of young exposed to COVID infection even in mild severity should be considered as emerging unmet need of mental health recovering: urgent health policy actions to boost the psychological, biological and social strategic pillar for young generation.

Household secondary attack rate in mild COVID-19.

Background: The coronavirus disease 2019 (COVID-19) pandemic has reached a staggering number of almost 280 million cases worldwide, with over 5.4 million deaths as of 29 December 2021. A further understanding of the factors related to the household spread of the infection might help to bring about specific protocols to curb such transmission. Objective: This study aims to find the secondary attack rate (SAR) and factors affecting SAR among the households of mild COVID-19 cases. Methods: An observational study was designed where data of patients admitted at All India Institute of Medical Sciences, New Delhi due to mild COVID-19 were collected, and outcome was noted after the discharge of the patient. Index cases who were the first in the household to have a positive infection only were included. Based on these data, the overall household SAR, factors related to the index case and contacts that affected transmissibility were noted. Results: A total of 60 index cases having contacts with 184 household members were included in the present study. The household SAR was measured to be 41.85%. At least one positive case was present in 51.67% households. Children below 18 years old had lower odds of getting a secondary infection compared to adults and elderly [odds ratio (OR) = 0.46, 95%CI = 0.22-0.94, p = 0.0383). An exposure period of more than a week was significantly associated with a higher risk of infection (p = 0.029). The rate of transmissibility drastically declined with effective quarantine measures adopted by the index case (OR = 0.13, 95%CI = 0.06-0.26, p < 0.00001). Symptomatic index cases contributed more to the SAR than asymptomatic primaries (OR = 4.74, 95%CI = 1.03-21.82, P = 0.045). Healthcare worker index cases had lower rates of spread (OR = 0.29, 95%CI = 0.15-0.58, P = 0.0003). Conclusion: The high SAR shows the household is a potential high-risk unit for transmissibility of COVID-19. Proper quarantine measures of all those exposed to the index case can mitigate such spread and lead to reduction of risk of COVID-19 within a household.

Branch Retinal Vein Occlusion After COVID-19 Infection: A Case Report.

A 65-year-old male patient presented to the ED complaining of blurred vision in the left eye for the last three days. The patient had just recovered from COVID-19 infection and had a negative polymerase chain reaction (PCR) test two days after the initiation of symptoms. His family and medical history were clear. Ophthalmological examination and imaging revealed branch retinal vein occlusion (BRVO) with macular edema in the left eye, while the right eye was normal. The visual acuity was 6/6 in the right eye and 6/36 in the left eye. Laboratory tests, as well as the full cardiovascular and thrombophilia evaluation, were normal. Since the patient did not have known risk factors for BRVO, we hypothesize that it was related to COVID-19 infection. However, the causality between the two entities remains under investigation.

Surveillance of RNase P, PMMoV, and CrAssphage in wastewater as indicators of human fecal concentration across urban sewer neighborhoods, Kentucky.

Wastewater surveillance has been widely used as a supplemental method to track the community infection levels of severe acute respiratory syndrome coronavirus 2. A gap exists in standardized reporting for fecal indicator concentrations, which can be used to calibrate the primary outcome concentrations from wastewater monitoring for use in epidemiological models. To address this, measurements of fecal indicator concentration among wastewater samples collected from sewers and treatment centers in four counties of Kentucky (N = 650) were examined. Results from the untransformed wastewater data over 4 months of sampling indicated that the fecal indicator concentration of human ribonuclease P (RNase P) ranged from 5.1 × 101 to 1.15 × 106 copies/ml, pepper mild mottle virus (PMMoV) ranged from 7.23 × 103 to 3.53 × 107 copies/ml, and cross-assembly phage (CrAssphage) ranged from 9.69 × 103 to 1.85 × 108 copies/ml. The results showed both regional and temporal variability. If fecal indicators are used as normalization factors, knowing the daily sewer system flow of the sample location may matter more than rainfall. RNase P, while it may be suitable as an internal amplification and sample adequacy control, has less utility than PMMoV and CrAssphage as a fecal indicator in wastewater samples when working at different sizes of catchment area. The choice of fecal indicator will impact the results of surveillance studies using this indicator to represent fecal load. Our results contribute broadly to an applicable standard normalization factor and assist in interpreting wastewater data in epidemiological modeling and monitoring.

The Relationship between Handgrip Strength, Timed Up-and-Go, and Mild Cognitive Impairment in Older People during COVID-19 Pandemic Restrictions.

The COVID-19 lockdown restrictions affected physical performance and cognitive function in older people as they were confined to their homes. There is an association between physical and cognitive functions. Mild Cognitive Impairment (MCI) is a condition that risks progressing to dementia. This study aimed to identify the relationship between handgrip strength (HGS), Timed Up-and-Go (TUG), and MCI in older people during the COVID-19 pandemic restrictions. The cross-sectional study recruited 464 eligible participants for an interview and anthropometric measurement. The Montreal Cognitive Assessment-Basic (MoCA-B), HGS, and TUG were measured in addition to demographic and health characteristics. A total of 398 participants (85.8%) were found to have MCI when screened with the MoCA-B. Their mean age was 71.09 ± 5.81 years. Forward multiple regression analysis demonstrated that HGS (ß = 0.032, p < 0.001), education level (ß = 2.801, p < 0.001), TUG (ß = -0.022, p = 0.013), Thai Geriatric Depression Score, TGDS (ß = -0.248, p = 0.011), and age (ß = -1.677, p = 0.019) were associated with MCI. A decrease in HGS and an increased TUG might allow for the early detection of MCI and promote physical training in order to reduce the risk of MCI. Further studies can investigate multidomain indicators for MCI, for example, fine motor skills and pinch strength as components of the motor abilities.

Tumor microenvironment-responsive gold nanodendrites for nanoprobe-based single-cell Raman imaging and tumor-targeted chemo-photothermal therapy

Nanodendrite particles (NDs) with densely branched structures and biomimetic architectures have exhibited great promise in tumor therapy owing to their prolonged in vivo circulation time and exceptional photothermal efficiency. Nevertheless, traditional NDs are deficient in terms of specific surface modification and targeting tumors, which restricts their potential for broader clinical applications. Here, we developed coronavirus-like gold NDs through a seed-mediated approach and using silk fibroin (SF) as a capping agent. Our results demonstrate that these NDs have a favorable drug-loading capacity (∼65.25%) and light-triggered release characteristics of doxorubicin hydrochloride (DOX). Additionally, NDs functionalized with specific probes exhibited exceptional surface-enhanced Raman scattering (SERS) characteristics, enabling high-sensitivity Raman imaging of unstained single cells. Moreover, these NDs allowed for real-time monitoring of endocytic NDs for over 24 h. Furthermore, ND@DOX conjugated with tumor-targeting peptides exhibited mild hyperthermia, minimal cytotoxicity, and effective targeting towards cancer cells in vitro, as well as responsiveness to the tumor microenvironment (TME) in vivo. These unique properties led to the highest level of synergistic tumor-killing efficiency when stimulated by a near-infrared (NIR) laser at 808 nm. Therefore, our virus-like ND functionalized with SF presents a novel type of nanocarrier that exhibits significant potential for synergistic applications in precision medicine.

Plasma UCHL1, GFAP, Tau, and NfL Are Not Different in Young Healthy Persons With Mild COVID-19 Symptoms Early in the Pandemic: A Pilot Study.

Elevated levels of brain injury biomarkers have been found primarily in middle-aged or older persons experiencing moderate-to-severe COVID-19 symptoms. However, there is little research in young adults, and there is concern that COVID-19 causes brain injury even in the absence of moderate-to-severe symptoms. Therefore, the purpose of our study was to investigate whether neurofilament light (NfL), glial fibrillary acidic protein (GFAP), tau, or ubiquitin carboxyl-terminal esterase L1 (UCHL1) are elevated in the plasma of young adults with mild COVID-19 symptoms. Twelve participants diagnosed with COVID-19 had plasma collected 1, 2, 3, and 4 months after diagnosis to determine whether NfL, GFAP, tau, and UCHL1 concentrations increased over time or whether plasma concentrations were elevated compared with COVID-19-naïve participants. We also compared plasma NfL, GFAP, tau, and UCHL1 concentrations between sexes. Our results showed no difference between NfL, GFAP, tau, and UCHL1 concentrations in COVID-19-naïve participants and COVID-19-positive participants at any of the four time points (p = 0.771). Within the COVID-19-positive participants, UCHL1 levels were higher at month 3 after diagnosis compared to month 1 or month 2 (p = 0.027). Between sexes, females were found to have higher UCHL1 (p = 0.003) and NfL (p = 0.037) plasma concentrations compared to males, whereas males had higher plasma tau concentrations than females (p = 0.024). Based on our data, it appears that mild COVID-19 in young adults does not increase plasma NfL, GFAP, tau, or UCHL1.

Computerized Cognitive Testing in Long COVID Patients With Prolonged Symptoms of Brain Fog and Cognitive Impairment

Purpose: To identify cognitive impairments in patients (pts) with long COVID using the Cambridge Brain Sciences (CBS) computerized cognitive test (CCT) commonly used to evaluate cognitive function after concussions and traumatic brain injuries. Method(s): Retrospective review from May 2021-Sept 2022 of 16 (4 male, 12 female) patients with long COVID, ages 13- 66 (avg 46), with average of 10 months from COVID infection to time of evaluation. Cognitive (cog) performance and concussion profile symptom scores were assessed with CBS CCT and the Concussion Clinical Profiles screening tool (CP screen) respectively. Result(s): The total CP symptom score average was 34/89 (ranging 7-68) in the cohort. The predominant profile was cog fatigue scoring (1.8/3) on average. CBS CCT tested cog impairment (CI) and was divided into 5 categories (0-4): no CI, borderline (scores between the 21st-30th percentile), mild (1 test < / = 20th percentile), moderate (2-3 tests < / = 20th percentile), and severe CI (>3 tests,/520th percentile). Data showed 2/16 (13%) patients had no CI, 5/16 (31%) had borderline CI, 5/16 (31%) had mild CI, 3/16 (19%) had moderate CI, and 1/16 (6%) pts had severe CI. Although not significant, there was a positive correlation between CI and cog profile score (P = 0.3149) when performing a linear regression test. Deficits were most common in the CBS CTT composites of grammatical reasoning/verbal processing and attention, with 4/16 patients scoring < 20th percentile for each test. The lowest average percentile scores for the cohort were in visuospatial processing and verbal short-term memory. Conclusion(s): Most long COVID patients assessed with CCT demonstrated signs of CI, in particular in verbal processing and memory, followed by visual processing. In addition to the CCT results illustrating CI, the top CP profile of cognitive fatigue in this cohort suggests that the brain fog experienced by long COVID patients may be quantified. Significance: CCT may be a useful tool in assessing and quantifying those with Long COVID with chronic symptoms of cognitive fog, fatigue, or impairment. Targeted interventions aimed at specific deficits can aid in treatment and recovery.

Mild Androgen Insensitivity Syndrome presenting in male with infertility and sexual difficulties

Androgen insensitivity syndrome has a wide spectrum of presentations. It results from a mutation in androgen receptor (AR) gene. It ranges from mild androgen insensitivity syndrome (MAIS) which is the mildest form to complete androgen insensitivity syndrome (CAIS). In case of MAIS, the abnormality that can be observed appears to be male infertility and sexual difficulties including premature ejaculation and erectile dysfunction. In this case report, we discuss a case of MAIS in a 37-year-old male who presented with infertility, premature ejaculation, and secondary erectile dysfunction.Copyright © 2023, Ibn Sina Trust.

Memory B cell development after asymptomatic or mild symptomatic SARS-CoV-2 infection.

BACKGROUND: The development of memory B cells after asymptomatic SARS-CoV-2 infection is not well understood. METHODS: We compared Spike antibody titers, pseudovirus neutralizing antibody titers, and memory B cell responses among SARS-CoV-2 PCR positive Marine recruits who either reported asymptomatic or symptomatic infection. RESULTS: 36 asymptomatic participants exhibited similar Spike IgG titers, Spike IgA titers, and pseudovirus neutralization titers compared to 30 symptomatic participants. Pseudovirus neutralization and Spike IgG titers showed significant positive correlations with frequency of memory B cells. CONCLUSIONS: Among young adults, asymptomatic SARS-CoV-2 infection induced antibody and memory B cell responses comparable to mild symptomatic infection.

Adopting a Telemedicine Model of Asthma Care during the Covid-19 Pandemic

Purpose of study The IMPACT DC Asthma Clinic is an intervention program designed to transition children who are heavily dependent on the emergency department for episodic care to more effective longitudinal asthma care in their primary medical homes. We sought to study the implementation of a telemedicine model for IMPACT DC during the COVID-19 pandemic in order to address barriers to care. Methods used A telemedicine model of IMPACT DC was implemented using rapid-cycle improvements and process mapping. Measures for adoption of services including visit completion, show rates, primary language, and patient satisfaction were collected for six months. Healthcare utilization data for the six months prior to the IMPACT DC clinical intervention was collected. This data was compared to in- person clinic visits over the same six-month period the previous year. Summary of results 360 patients successfully completed a telemedicine visit between April 2020 and September 2020 with an average visit show rate of 52%. Primary language was English in 89%. These patients were most frequently classified as having mild-persistent asthma and were assessed as well-controlled. Satisfaction survey response rate was 33%;overall average satisfaction was high. In the comparison group, 701 patients successfully completed an in-person clinic visit between April 2019 and September 2019 with a visit show rate of 39%. Primary language was English in 84%. These patients were most frequently classified as having mild-persistent asthma, not well-controlled. Healthcare utilization data for both groups six months prior to their visit are displayed Conclusions The use of telemedicine provides IMPACT DC a feasible and adoptable model to continue caring for children with asthma, with overall high patient satisfaction. This model addresses access barriers during the pandemic, and promises to be an adjunctive tool for reaching families with low show rates and high healthcare utilization. (Table Presented).

Management of patients with cognitive impairment.

The management of patients with cognitive impairment (CI) is one of the urgent problems of modern medicine. Issues of diagnostics and therapy of patients with CI and their high mortality during the period of coronavirus infection are discussed. A wide prevalence of patients with mild CI (MCI), an important role of neuropsychological research in establishing CI, and frequent diagnosis of CI only at the stage of dementia were noted. In our country, CI is poorly diagnosed, the most common cause of CI in the elderly - Alzheimer's disease (AD) - is rarely established, patients are observed for a long time with a diagnosis of cerebrovascular disease (CVD). Some non-drug and drug methods can reduce the manifestations of CI, improve the quality of life of both the patients themselves and those around them. In severe CI, socio-psychological methods, stimulating patients to feasible household and social, physical and mental activity, and avoiding prolonged hospitalization are of primary importance. In addition to lifestyle changes, much attention in CI is given to the prevention of stroke, the treatment of arterial hypertension and diabetes mellitus. At the stage of dementia, cholinomimetic drugs (acetylcholinesterase inhibitors, donepezil, rivastigmine, galantamine) and the glutamate receptor blocker memantine are used. The use of choline alfoscerate in CI and the results of the multicenter, placebo-controlled ASCOMALVA study are discussed, in which, in patients with AD and CVD, the addition of choline alfoscerate to donepezil reduced the severity of CI, manifestations of depression, anxiety, and apathy. A new oral form of choline alfoscerate (Cerpechol) is reported that may improve patient compliance and be used in patients with swallowing disorders.Copyright © 2023 Ima-Press Publishing House.

SARS-CoV-2 susceptibility and COVID-19 illness course and outcome in people with pre-existing neurodegenerative disorders: systematic review with frequentist and Bayesian meta-analyses.

BACKGROUND: People with neurodegenerative disease and mild cognitive impairment (MCI) may have an elevated risk of acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and may be disproportionally affected by coronavirus disease 2019 (COVID-19) once infected. AIMS: To review all eligible studies and quantify the strength of associations between various pre-existing neurodegenerative disorders and both SARS-CoV-2 susceptibility and COVID-19 illness course and outcome. METHOD: Pre-registered systematic review with frequentist and Bayesian meta-analyses. Systematic searches were executed in PubMed, Web of Science and preprint servers. The final search date was 9 January 2023. Odds ratios (ORs) were used as measures of effect. RESULTS: In total, 136 primary studies (total sample size n = 97 643 494), reporting on 268 effect-size estimates, met the inclusion criteria. The odds for a positive SARS-CoV-2 test result were increased for people with pre-existing dementia (OR = 1.83, 95% CI 1.16-2.87), Alzheimer's disease (OR = 2.86, 95% CI 1.44-5.66) and Parkinson's disease (OR = 1.65, 95% CI 1.34-2.04). People with pre-existing dementia were more likely to experience a relatively severe COVID-19 course, once infected (OR = 1.43, 95% CI 1.00-2.03). People with pre-existing dementia or Alzheimer's disease were at increased risk for COVID-19-related hospital admission (pooled OR range: 1.60-3.72). Intensive care unit admission rates were relatively low for people with dementia (OR = 0.54, 95% CI 0.40-0.74). All neurodegenerative disorders, including MCI, were at higher risk for COVID-19-related mortality (pooled OR range: 1.56-2.27). CONCLUSIONS: Our findings confirm that, in general, people with neurodegenerative disease and MCI are at a disproportionally high risk of contracting COVID-19 and have a poor outcome once infected.

Bioinformatic assay reveal the potential mechanism of Guizhi-Shaoyao-Zhimu decoction against rheumatoid arthritis and mild-to-moderate COVID-19.

BACKGROUND AND OBJECTIVE: Patients with rheumatoid arthritis (RA) are more susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) than healthy population, but there is still no therapeutic strategy available for RA patients with corona virus disease 2019 (COVID-19). Guizhi-Shaoyao-Zhimu decoction (GSZD), Chinese ancient experience decoction, has a significant effect on the treatment of Rheumatism and gout. To prevent RA patients with mild-to-moderate COVID-19 from developing into severe COVID-19, this study explored the potential possibility and mechanism of GSZD in the treatment of this population. METHODS: In this study, we used bioinformatic approaches to explore common pharmacological targets and signaling pathways between RA and mild-to-moderate COVID-19, and to assess the potential mechanisms of in the treatment of patients with both diseases. Beside, molecular docking was used to explore the molecular interactions between GSZD and SARS-CoV-2 related proteins. RESULTS: Results showed that 1183 common targets were found in mild-to-moderate COVID-19 and RA, of which TNF was the most critical target. The crosstalk signaling pathways of the two diseases focused on innate immunity and T cells pathways. In addition, GSZD intervened in RA and mild-to-moderate COVID-19 mainly by regulating inflammation-related signaling pathways and oxidative stress. Twenty hub compounds in GSZD exhibited good binding potential to SARS-CoV-2 spike (S) protein, 3C-like protease (3CLpro), RNA-dependent RNA polymerase (RdRp), papain-like protease (PLpro) and human angiotensin-converting enzyme 2 (ACE2), thereby intervening in viral infection, replication and transcription. CONCLUSIONS: This finding provides a therapeutic option for RA patients against mild-to-moderate COVID-19, but further clinical validation is still needed.

Autoantibody-negative but probable pediatric autoimmune encephalitis following COVID-19 vaccination: A case report

Background: Large-scale vaccination against the novel coronavirus (COVID-19) occurred globally at an unprecedented pace. Sporadic cases of autoimmune encephalitis (AE) have been reported following COVID-19 vaccination, mainly in adults. Case report: A 14-year-old girl developed altered mental status and was brought to our emergency department because of a seizure 19 days after receiving the third dose of COVID-19 vaccination. She was treated with steroid pulse therapy and fully recovered. The diagnosis of probable autoantibody-negative AE was finally made. Conclusion(s): This case met the criteria for probable autoantibody-negative AE in children, as well as adults. Because of the temporal association and absence of another identifiable cause, her conditions may have been triggered by the COVID-19 vaccination. To our knowledge, this is the first published pediatric case of autoantibody-negative but probable AE following COVID-19 vaccination.Copyright © 2023 The Authors

Persistent allergic respiratory symptoms induced by food allergy: Report of two cases

Case report Dust is a known mixture and carrier of multiple allergens and an epidemiologic study demonstrated the presence of peanut proteins in school cafeterias and classrooms, suggesting that schools may play an important role in exposure to environmental food allergens. While inhalation of food allergens is a known trigger of IgE-mediate acute respiratory reaction as rhinitis and wheezing, little is known about persistent allergic asthma and/or rhinitis induced by chronic inhalation of food allergens. Here we report two cases of teenagers with nuts allergy presenting with persistent respiratory symptoms when exposed to closed and dusty environments. The first case concerns a 12-year-old boy allergic to walnut and hazelnut (specific IgE > 100 and 81.70 kU/l, respectively). For some years he has had a persistent mild asthma, frequent nasal occlusion and rhinorrhea, without any allergic sensitization to aeroallergens. Symptoms occurred exclusively during school period when he required maintenance therapy with inhaled and nasal steroids. He was asymptomatic and did not need any treatment during summer. During the lockdown period due to Covid-19 pandemic, he did not attend school for several months and he was able to discontinue inhaled corticosteroid therapy without recurrence of asthma and rhinitis symptoms. Asthma recurred after he returned to school, but with only mild intermittent symptoms, probably thanks to the use of masks and the frequent airing of the classrooms. On a single occasion he experienced nasal occlusion and rhinorrhea after that a parent had eaten hazelnut cream in the same room where he was. The second case deals with a 17-year-old boy with a history of several food allergies (milk, egg, wheat, banana, nuts, hazelnuts) and mild persistent asthma in absence of sensitization to aeroallergens. He successfully underwent oral desensitization for milk, egg and wheat in previous years. Asthma symptoms improved over the years together with progressive development of oral tolerance to food allergens for which oral immunotherapy had been done. On the other hand, he referred persistence of allergic rhinitis especially during the school year and his symptoms got worse in classroom. Exhaled nitric oxide was quite increased with evidence of eosinophils in nasal smears. In-vitro and in-vivo tests only detected food allergens sensitizations, in particolar to walnuts and hazelnuts (specific IgE were 61.00 and 55.50 kU/l respectively). These two clinical cases suggest that food allergens might be causative agents of allergic persistent asthma and/or rhinitis as aeroallergens do.

The impact of neurocognitive impairment on daily life functioning in older adults

The MMSE is one of the most widely used in-person cognitive screeners to assess global cognitive impairment (Folstein, 1975;Fong et al., 2009). The TICS, which is a cognitive screener that can be administered over the telephone, has been found to be highly correlated with the MMSE (Brandt et al., 1988). There is a lack of research comparing the MMSE and TICS ability to predict daily life functioning in older adults with varying degrees of cognitive abilities. Thus, this study examined the utility of the TICS-40 and MMSE to predict daily life functioning at different levels of cognitive impairment (mild cognitive impairment and dementia). Taken from the Aging, Demographics, and Memory Study (Plassman et al., 2007), a sample of 157 participants over the age of 70 with mild cognitive impairment or dementia were administered a battery of surveys and tests that included the MMSE, the TICS-40, the index of activities of daily living (ADLs), and the measure of instrumental activities of daily living (IADLs, Lawton & Brody, 1969). The TICS and MMSE similarly predicted daily life functioning in the total sample and MCI group (n = 133). The MMSE was a better predictor in the dementia group (n = 24) than in the MCI group. Higher scores on both screeners predicted problems with telephone use and medication management in the MCI group. In the dementia group, higher MMSE scores showed marginal support for fewer problems with telephone use and medication management, while higher TICS scores predicted fewer problems with medication management. Investing resources in the development and knowledge of cognitive screeners and procedures for remote administration would benefit older adults. Regularly screening older adults in their homes may lead to earlier detection of decline, better treatment, allocation of more appropriate resources, and improvement in quality of life for older adults who are unable to meet with clinicians in an in-person setting due to illness such as COVID-19, physical disability, or those living in rural areas.

Idiopathic anomalous congenital band causing small intestinal obstruction in a 5-month-old dog

A 5-month-old, intact male, yellow Labrador retriever was presented with a 24-hour history of anorexia and vomiting. Abdominal imaging revealed the presence of a mechanical obstruction in the jejunum and peritoneal effusion. Cytologic evaluation and culture of the effusion prior to surgery identified a suppurative exudate with bacteria consistent with septic peritonitis and suspected to be related to the intestinal lesion. An exploratory laparotomy was performed, and a segment of jejunum was circumferentially severely constricted by an off-white, fibrous band of tissue. Resection and anastomosis of the strangulated segment of jejunum and excision of the constricting band provided resolution of the clinical signs. The dog made a complete recovery. Histologic evaluation revealed the band to be composed of fibrovascular and smooth muscle tissue, consistent with an idiopathic anomalous congenital band. No other gastrointestinal lesions were observed, either grossly at surgery or histologically in the resected segment of intestine. To our knowledge, a similar structure has not been reported in the veterinary literature.Copyright © 2022 Canadian Veterinary Medical Association. All rights reserved.
