Frailty Prevalence, Incidence, and Association with Incident Disability in the Italian Longitudinal Study on Aging

Introduction: Data on frailty frequency are heterogeneous and mostly based on cross-sectional studies. Little is known about frailty development and progression over time. Our aim was to conduct a systematic analysis of frailty prevalence and incidence in a large cohort of older adults and to evaluate the association with incident disability, in order to tackle the current paucity and fragmentation of longitudinal data on frailty. Methods: As secondary analysis of the Italian Longitudinal Study on Aging (ILSA) population-based cohort (n = 5,632, 65–84), frailty status was operationalized according to Fried criteria (n = 2,457). Weighted prevalence and incidence rates were calculated at each ILSA wave (T0 1992–1993, T1 1995–1996, T2 2000–2001). The association with incident disability in Activities of Daily Living (ADL) or Instrumental Activities of Daily Living (IADL) was investigated through Cox proportional hazard models, controlling for possible confounders. Results: Prevalence of frailty and pre-frailty at baseline (mean age 71.6 years; women 58.9%) were 4.0% (95% confidence interval [CI]: 3.4–4.6) and 44.6% (95% CI: 43.1–46.1), respectively. Incidence rates per 1,000 person-years for the T0–T1 interval were 7.3 (95% CI: 5.2–9.3) for frailty and 83.7 (95% CI: 73.6–93.8) for pre-frailty. Prevalence and incidence of frailty, and to a lesser degree of pre-frailty, were overall higher for women and increased with age, yet no increasing trend with advancing age was detected for pre-frailty incidence. Frailty incidence rates were significantly higher among pre-frail than non-frail individuals at follow-up entry. After full adjustment, being frail markedly increased the risk of incident disability in ADL (hazard ratio [HR] 3.58, 95% CI: 1.97–6.52) and IADL (HR 2.56, 95% CI: 1.58–4.16) over a 4-year period. Discussion/Conclusion: According to our findings, frailty is common among older people and is a strong and independent predictor of disability. Further research on factors and characteristics related to frailty progression, and especially remission, over time is crucial to calibrate effective public health preventive measures.

Effect of NPK and silicon fertilizer on growth, flowering, and nectar of Turnera ulmifolia L.

Turnera ulmifolia L. is a beneficial plant mostly planted in the oil palm plantation as it is easily adapting to a variety of environmental conditions, mainly to conserve beneficial insects. Nevertheless, the planted plants were left without proper maintenance and less study was conducted on biological control agent conservation. Thus, this study aimed to examine the effect of NPK, silicon fertilizer and their combination on the growth and development of T. ulmifolia. Treatments including T0 Control (No fertilization application), T1 (0.2 g NPK), T2 (0.2 g NPK+3.9 g silicon), T3 (0.2 g NPK+4.9 g silicon), T4 (3.9 g silicon) and T5 (4.9 g silicon) were applied 20 days after transplanting at monthly interval for three months. Results revealed the greatest height and number of branches were observed in T1. Overall, the chlorophyll content ranged between 27.92 to 31.18 SPAD values. All treatments gave the same effect on morphometric measurements on the first 30 days of observation. After 60 days, the greatest value for broad tube width and length was observed in T4 which differs significantly from other treatments. The application of fertilizer in T1, T2 and T3 showed 10-20% promotive effects over the control in the amount of nectar produced per flower. For all three observation periods, a similar trend was recorded for the total sugar concentration in flowers, where the mean total sugar content was between 1.37 and 1.61 mg per flower.

Performance, carcass and meat quality of broilers raised at a high stocking density and supplemented with encapsulated Cosmos caudatus K. leaf extract

The aim of this study was to determine the effect of supplementation of encapsulated Cosmos cau-datus K. leaf extract (ECLE) on performance, carcass and meat quality of broilers at high density pens. Three hundred and seventy broiler chicks were divided into 5 treatments and 5 replications. The treat-ment was conducted on days 15 to 42 in T0 group (10 chicks/m2 + basal feed), T1 (16 chicks/m2 + ba-sal feed), T2 (16 chicks/m2 + basal feed containing ECLE 0.5 g/kg feed), T3 (16 chicks/m2 + ECLE 1.0 g/kg feed), and T4 (16 head/m2 + ECLE 1.5 g/kg feed). ECLE reduced feed consumption, increased body weight gain, improved feed conversion ratio (FCR), increased the European Production Efficien-cy Factor (EPEF) and European Broiler Index (EBI) in T2 and T3 (P<0.05). Carcass weight and per-centage were increased in T3 and T4 (P<0.05). Breast percentage was higher (P<0.05) in T0, T1 and T2; wing and thigh percentages were higher (P<0.05) in T3 and T4; drumstick and giblet percentages were lower (P<0.05) in T3. Drumstick’s pH were higher (P<0.05) in T2, T3 and T4. Thigh fat de-creased (P<0.05) at T4. The redness (a*) in T3 and T4 were significantly better. Overall, at high densi-ty pens, ECLE at 0.5 g/kg feed enhanced broiler performance, carcass percentage, and breast meat quality.

How training loads in the preparation and competitive period affect the biochemical indicators of training stress in youth soccer players?

BackgroundPhysical fitness optimization and injury risk-reducing require extensive monitoring of training loads and athletes’ fatigue status. This study aimed to investigate the effect of a 6-month training program on the training-related stress indicators (creatine kinase – CK; cortisol – COR; serotonin – SER; brain-derived neurotrophic factor – BDNF) in youth soccer players.MethodsEighteen players (17.8 ± 0.9 years old, body height 181.6 ± 6.9 cm, training experience 9.7 ± 1.7 years) were blood-tested four times: at the start of the preparation period (T0), immediately following the preparation period (T1), mid-competitive period (T2), and at the end of the competitive period (T3). CK activity as well as concentrations of serum COR, SER and BDNF were determined. Training loads were recorded using a session rating of perceived exertion (sRPE).ResultsStatistical analyzes revealed significant effects for all biochemical parameters in relation to their time measurements (T0, T1, T2, T3). The statistical analyzes of sRPE and differences of biochemical parameters in their subsequent measurements (T0–T1, T1–T2, T2–T3) also demonstrated significant effects observed for all variables: sRPE (HKW = 13.189 (df = 2); p = 0.00), COR (HKW = 9.261 (df = 2); p = 0.01), CK (HKW = 12.492 (df = 2); p = 0.00), SER (HKW = 7.781 (df = 2); p = 0.02) and BDNF (HKW = 15.160 (df = 2); p < 0.001).DiscussionIn conclusion, it should be stated that the most demanding training loads applied in the preparation period (highest sRPE values) resulted in a significant increase in all analyzed biochemical training stress indicators. The reduction in the training loads during a competitive period and the addition of recovery training sessions resulted in a systematic decrease in the values of the measured biochemical indicators. The results of the study showed that both subjective and objective markers, including training loads, are useful in monitoring training stress in youth soccer players.

Electrophysiological evidence of the amodal representation of symmetry in extrastriate areas

Extrastriate visual areas are strongly activated by image symmetry. Less is known about symmetry representation at object-level rather than image-level. Here we investigated electrophysiological responses to symmetry, generated by amodal completion of partially-occluded polygon shapes. We used a similar paradigm in four experiments (N = 112). A fully-visible abstract shape (either symmetric or asymmetric) was presented for 250 ms (t0). A large rectangle covered it entirely for 250 ms (t1) and then moved to one side to reveal one half of the shape hidden behind (t2, 1000 ms). Note that at t2 no symmetry could be extracted from retinal image information. In half of the trials the shape was the same as previously presented, in the other trials it was replaced by a novel shape. Participants matched shapes similarity (Exp. 1 and Exp. 2), or their colour (Exp. 3) or the orientation of a triangle superimposed to the shapes (Exp. 4). The fully-visible shapes (t0–t1) elicited automatic symmetry-specific ERP responses in all experiments. Importantly, there was an exposure-dependent symmetry-response to the occluded shapes that were recognised as previously seen (t2). Exp. 2 and Exp.4 confirmed this second ERP (t2) did not reflect a reinforcement of a residual carry-over response from t0. We conclude that the extrastriate symmetry-network can achieve amodal representation of symmetry from occluded objects that have been previously experienced as wholes.

The granulation tissue preservation technique in regenerative periodontal surgery-a randomized controlled clinical trial.

ObjectivesTo investigate if the application of the granulation tissue preservation technique (GTPT) in regenerative therapy of infrabony periodontal defects results in more clinical attachment level (CAL) gain and more radiographic bone gain (RBG) than the conventional resective approach 12 months after surgery.Materials and methodsForty patients exhibiting at least one infrabony defect with a probing pocket depth (PPD) ≥6 mm and a radiographic infrabony component (INFRAX‐ray) ≥3 mm were randomly treated with the GTPT (test group) or the double‐flap approach with resection of the defect‐filling granulation tissue (control group). Enamel matrix derivatives were applied in both groups. Clinical and radiographic parameters were recorded at baseline (t0), 6 months (t1), and 12 months (t2) after surgery. The primary outcome variable was CAL gain between t0 and t2.ResultsWhen all patients were considered, ΔCALt0–t2 did not differ significantly between the two groups (p = .160). Significant PPD reduction (test group: 4.38 ± 1.36 mm; control group: 4.06 ± 2.38 mm), CAL gain (test group: 3.75 ± 1.24 mm; control group: 2.88 ± 2.09 mm), and RBG (test group: 3.06 ± 1.74 mm; control group: 3.27 ± 2.19 mm) were achieved at t2 in both groups. Using multivariate linear regression, PPDt0 and group were identified as variables with the greatest influence on ΔCALt0–t2. PPDt0 and INFRAX‐ray were identified as variables with the greatest influence on RBGt0–t2. Patients with a defect angle >22° showed significantly more CAL gain in the test group (t0–t1: 3.08 ± 1.38 mm; t0–t2: 3.62 ± 0.96 mm) than in the control group (t0–t1: 1.77 ± 1.54 mm; t0–t2: 2.18 ± 1.83 mm).ConclusionsRegarding all patients, the study failed to show significant differences between the test and control groups. However, the GTPT appears to lead to more CAL gain in noncontaining infrabony defects.

Cognitive Training via a Mobile Application to Reduce Obsessive-Compulsive-Related Distress and Cognitions During the COVID-19 Outbreaks: A Randomized Controlled Trial Using a Subclinical Cohort

Obsessive-compulsive disorder (OCD) is a persistent psychiatric disorder causing significant impairment in functioning. The COVID-19 pandemic has exacerbated OCD-related symptoms and interrupted access to treatment. Recent research suggests mHealth apps are promising tools for coping with OCD symptoms. This randomized controlled trial evaluated the effects of a CBT-based mobile application designed to reduce OCD symptoms and cognitions in community participants considered at high risk of developing OCD symptoms. Following initial screening (n = 924), fifty-five community participants scoring 2 standard deviations above the OCI-R mean were randomized into two groups. In the immediate-app use group (iApp; n = 25), participants started using the application at baseline (T0), 4 min a day, for 12 days (T0–T1). Participants in the delayed-app group (dApp; n = 20) started using the mobile application at T1 (crossover) and used the app for the following 12 consecutive days (T1–T2). Intention to treat analyses indicated that using the app for 12 consecutive days was associated with large effect-size reductions (Cohen’s d ranging from .87 to 2.73) in OCD symptoms and maladaptive cognitions in the iApp group (from T0 to T1) and dApp group (from T1 to T2). These reductions were maintained at follow-up. Our findings underscore the usefulness of brief, low-intensity, portable interventions in reducing OCD symptoms and cognitions during the pandemic.

Effects of Class II elastics during growth on the functional occlusal plane according to skeletal pattern and extraction vs nonextraction.

To investigate the effect of Class II intermaxillary elastics on the functional occlusal plane (FOP) of growing patients. A total of 50 participants aged 11 to 16 years were selected from a university clinic archive >1-year after treatment and after undergoing 6 months of Class II elastic wear, taking pretreatment (T0) and posttreatment (T1) lateral cephalometric radiographs, and consenting to participate at recall (T2). Participants were divided into 3 groups according to skeletal pattern or into 2 groups according to treatment with extraction (E) or nonextraction (NE). Angular changes of FOP relative to the Sella-Nasion (SN), mandibular plane (MP), and Frankfort horizontal (FH) were compared within and between groups. A statistically significant reduction of FOP-SN/FH, but not of FOP-MP, was found from T0-T1-T2 when all patients were grouped together. FOP-SN/MP/FH was significantly the largest in the patients with a hyperdivergent skeletal pattern, but lowest in the patients with a hypodivergent skeletal pattern at T0, T1, and T2 (P < .032). FOP-MP at T0-T2 was statistically larger in group E than in group NE (P < .02). No differences were found for FOP changes (change before treatment minus after treatment and change after treatment minus 1 year after treatment) between different skeletal patterns (P > .433) and treatment groups (P > .193). Use of Class II elastics during the growth period was not found to show adverse effects on FOP rotation. Neither skeletal pattern nor treatment modality differed in the response to Class II elastics with regard to FOP changes. Individual patient growth pattern must be taken into consideration when treatment planning the use of Class II elastics. Orthodontists should take into account individual skeletal and growth patterns while using Class II elastics.

Effect of a community-based lifestyle intervention programme on quality of life among German women

Abstract Background Quality of life is an important concept in the field of health, which can be influenced by various lifestyle factors. The objective was to test if a community-based lifestyle programme would beneficially affect the health-related quality of life of German women. Methods The controlled intervention study had a total duration of 24 months. Quality of life (EQ-5D-3L), anthropometrics, vital and blood parameters as well as diagnosed diseases and health economic parameters were collected at baseline (t0), after 10 weeks (t1) and after 6 months (t2). For the intervention group (n = 65) a 10-week intensive lifestyle programme followed by monthly alumni meetings were conducted. The intensive phase consisted of 14 consecutive seminars about a healthy lifestyle, which focused on a plant-based diet, physical activity, stress management and community support. The control group (n = 35) received no intervention. Results The first descriptive health profile results of the subgroup analysis showed that 59% women of the intervention group at t0 (t1: 37%; t2: 48%) and 60% of the control group at t0 (t1: 54%; t2: 49%) reported problems in at least one of the EQ-5D dimensions (mobility, selfcare, activities, pain, and anxiety). A significant difference in EQ VAS change between women in intervention (7,15 [95% CI 4,32; 9,98]; EQ VAS t0: 75,35 [SD 13,71]) and control group (-2,63 [95% CI -5,40; 0,15]; EQ VAS t0: 78,80 [SD 18,51]) from t0 to t1 was observed (p &amp;lt; 001; adjusted for baseline). No significant differences in mean EQ VAS change from t0 to t2 and in mean EQ-5D index change from t0 to t1 and t0 to t2 between the groups were observed (p &amp;gt; 0,05; adjusted for baseline). Conclusions The preliminary results suggest that the lifestyle intervention programme can have a positive short-time effect on some aspects of quality of life, such as the health profile and EQ VAS. However, the long-term results will be shown in the future. Key messages A healthy lifestyle can affect the quality of life in a positive way. The community-based lifestyle programme had a short-time influence on the descriptive health profile and EQ VAS of German women, whereby the EQ index didńt change significantly between the groups.

A Short Media Training Session Is Effective in Reinforcing Psychiatrists' Communication Skills About Suicide.

Because it has been associated with significant increases [through the Werther Effect (WE)] or decreases [through the Papageno Effect (PE)] of suicide rates, media coverage of suicide-related events is recognized as a prevention leverage. Unfortunately, the recommendations that the World Health Organization (WHO) has published to help journalists reporting on suicide remain poorly applied. The Mini Media Training (MMT) is a short media training session designed to increase psychiatrists’ ability to communicate about suicide during interviews. We aimed at assessing the effect of the MMT on psychiatrists’ ability to help journalists complying with the WHO recommendations. From June 2017 to December 2019, 173 physicians and residents in psychiatry were recruited during French national congresses. At baseline (T0) and 1 and 3 months later (T1), participants received the MMT, which consisted in a simulated interview where they we asked to answer a journalist about a mock suicide. Communication skills were measured with a score summing the number of delivered pieces of advice in relation to the WHO recommendations, with a maximum score of 33. A weighted score was also derived based on the degree of directivity needed for the participant to provide these items, again with a possible maximum of 33. A total of 132 psychiatrists participated in the study at T0 and T1. Both the weighted and unweighted score significantly increased from T0 to T1 (d = +2.08, p < 0.001, and d = +1.24, p < 0.001, respectively). Having a history of contacts with journalists, a short professional experience (<3 years) and prior knowledge of the WE, PE, and WHO recommendations were significantly associated with greater unweighted and weighted scores at baseline. The latter two variables also predicted greater T0–T1 improvement of the weighted score. These results suggest that the MMT could be effective for improving the ability of psychiatrists to guide journalists toward more responsible media coverage of suicide. As a short, easy to implement educational activity, the MMT could therefore be considered in association with other measures to help media professionals mitigating the WE and promoting the PE.

Clinical and morphological characteristic of kidney damage in HIV/HCV co-infected patients who did not receive antiretroviral therapy

In the era of antiretroviral therapy (ART), the development of chronic kidney disease in HIV-infected patients is a significant complication not directly related to acquired immunodeficiency syndrome (AIDS), the risk of which is increased with co-infection with hepatitis C virus (HCV). The pathogenetic pathways of the development of kidney tissue damage and the formation of a morphological substrate for each of the viruses are different, but the immune-mediated mechanisms are a common link for the development of immune complex diseases. We studied renal necropsy samples in 20 patients with HIV/HCV co-infection who did not receive ART, and the dependence of the identified morphological substrate on the level of CD4+ in the blood, to assess and predict their morphogenesis. We observed predominantly segmental mesangial proliferation with an expansion of the mesangial matrix and glomerular involvement ≥50 % in 15 (75 %) cases and glomerular involvement &lt;50 % in 3 (15 %) cases. Endocapillary proliferation (E), infiltration of glomeruli with monocytes, neutrophil leukocytes, segmental macrophages were found in 2 (10 %) cases with the involvement of ≥ 50 % of glomeruli, which was regarded as an exudative component of the inflammatory response. In all cases, sclerosis of capillary loops was verified, which was mainly accompanied by their collapse, thickening of the capillary walls, namely the basement membranes of capillaries and segmental sclerosis of capillary loops of the glo­meruli of varying severity. Initial interstitial stromal fibrosis was found in 5 (25 %) cases, degenerative changes in the convoluted tubules — in 9 (45 %), mainly with the T0–T1 level. Positive expression of IgA, IgM, IgG, and C3 complement fractions in the form of linear and granular deposits along the capillary endothelium was detected with an intensity of “+” to “++”. We compared the verified morphological pattern and the level of CD4+ in the blood and found that patients with deeper immunosuppression show fewer changes, mainly characterized as sclerotic. Moreover, with an increase in the level of CD4+, the morphological substrate is enriched with a proliferative component. Expression of immunoglobulins and components of the complement system in immonohistochemical assay, in particular in areas of sclerotic changes, verifies the presence of prolonged immune complex associated lesions. To determine the detailed morphogenesis, it is advisable to perform a further correlation analysis of the data obtained with the control.

Three-dimensional evaluation of long-term skeletal relapse following Le Fort I maxillary advancement surgery: a 2-year follow-up study

The aim of this study was to assess relapse following Le Fort I (LFI) maxillary advancement with superior or inferior repositioning at 2 years of follow-up. A total of 50 patients (26 female, 24 male; age range 15–56 years) with skeletal class II or III, who underwent bimaxillary surgery with LFI maxillary advancement in combination with either superior or inferior repositioning and also mandibular advancement/setback, were recruited. Preoperative (T0), immediate postoperative (T1), and 2-year postoperative (T2) cone beam computed tomography scans were acquired. Data were imported into a validated module to assess the skeletal movement (T0–T1) and relapse (T1–T2). Overall, the majority of the translational and rotational movements showed a relapse of <1 mm and <1°. Patients undergoing maxillary advancement with inferior repositioning in combination with mandibular advancement showed the highest amount of translational relapse in a superior (0.86 ± 0.85 mm, P < 0.0001) and posterior direction (−0.65 ± 1.11 mm, P < 0.0001). In relation to patients who received a bone graft, inferior repositioning with mandibular setback showed the highest maxillary relapse in a superior direction (1.20 ± 1.56 mm, P = 0.0719) with counterclockwise pitch rotation (2.15 ± 0.64°, P = 0.3759). Amongst the non-grafted procedures, superior repositioning with mandibular setback exhibited the highest relapse in a medial direction (1.38 ± 2.78 mm, P = 0.3981). Maxillary advancement was found to be a highly stable procedure with a lack of superoinferior stability in patients undergoing inferior repositioning.

A Randomized Controlled Trial Evaluating Integrative Psychotherapeutic Group Treatment Compared to Self-Help Groups in Functional Vertigo/Dizziness.

We tested the efficacy of an integrative psychotherapeutic group treatment (IPGT) in reducing vertigo/dizziness-related impairment along with depression, anxiety, and somatization by conducting a randomized controlled superiority trial comparing IPGT to self-help groups moderated by a clinical psychologist (SHG). Adult patients with functional vertigo and dizziness symptoms were randomly allocated to either the IPGT or SHG as active control group. Outcomes were assessed at baseline (t0), after treatment lasting 16 weeks (t1), and 12 months after treatment (t2). A total of 81 patients were assigned to IPGT and 78 patients were assigned to SHG. Vertigo-related impairment was reduced in both conditions (IPGT: t0–t1: d = 1.10, t0–t2: d = 1.06; SHG: t0–t1: d = 0.86, t0–t2: d = 1.29), showing the efficiency of both IPGT and SHG. Clinically relevant improvements were also obtained for depression in both groups. Linear mixed model analyses revealed no differences between groups for all outcomes (effect of group for the primary outcome: b = −1.15, SE = 2.13, t = −0.54, p = 0.59). Attrition rates were higher in SHG (52.6%) than in IPGT (28.4%). Both conditions improved primary and secondary outcomes while IPGT was better accepted by patients than SHG.

Phase-II study of toripalimab combined with neoadjuvant chemotherapy for the treatment of resectable esophageal squamous cell carcinoma.

e16029 Background: Compared with neoadjuvant chemotherapy alone，Neoadjuvant radiochemotherapy can significantly increase pCR rate in esophageal squamous cell carcinoma and improve patient overall survival. However, the addition of radiotherapy increases the risk of adverse reactions and surgery. Neoadjuvant radiochemotherapy is currently used in &lt; 5% of Chinese patients.The purpose of this phase II study is to assess the efficacy and safety of toripalimab combined with paclitaxel and cisplatin as neoadjuvant treatment for resectable locally advanced esophageal squamous cell carcinoma(clinical trial registration number: ChiCTR1900025318). Methods: Patients 18–75 years old with esophageal squamous cell carcinoma confirmed by endoscopic biopsy, assessed to be locally advanced esophageal squamous cell carcinoma (cT1–cT2, N+; cT3–cT4 a, any N), and expected to be resectable were given toripalimab (240 mg d1 + PTX 175 mg/m2 + PDD 75 mg/m2 q3w) before surgery for two treatment cycles, followed by efficacy assessment. A consultation meeting with thoracic surgeons was held to assess radical surgery for patients with resectable lesions 4–6 weeks after neoadjuvant therapy was completed. pCR and postoperative-stage statistical analysis were conducted based on postoperative pathology test results. These results were used to determine the efficacy and safety of PD-1 monoclonal antibody combined with chemotherapy as neoadjuvant therapy for locally advanced esophageal cancer. Results: By December 2020, 23 subjects were enrolled. Of the subjects, five withdrew without undergoing surgery (three subjects refused surgery and switched to radical radiochemotherapy, one subject progressed to PD after two cycles of neoadjuvant therapy and switched to palliative treatment, and one subject could not undergo surgery after neoadjuvant treatment and gave up the treatment) and 18 evaluable patients underwent surgery. The R0 resection rate was 100%, and T0–Tis 33.3% (6/18) achieved pCR. Among these patients, 61.1% (11/18) achieved T0–T1 after surgery, and 72.2% (13/18) achieved N0. Moreover, stage reduction effects were significant compared with preoperative TN staging. Common side-effects include nausea, vomiting, neutropenia, thrombocytopenia, rash, asthenia, constipation, and muscle soreness. Most adverse events were grades 1–2, and grades 3/4 adverse events include one case of grade 3 neutropenia and one case of grade 3 diarrhea (suspected immune-related colitis), which improved after symptomatic treatment. Conclusions: Toripalimab combined with the TP scheme showed preliminary efficacy and controllable safety in the treatment of resectable locally advanced esophageal squamous cell carcinoma and is worthy of further exploration.

Effects of prolonged interruption of rehabilitation routines in amyotrophic lateral sclerosis patients.

Patients with amyotrophic lateral sclerosis (ALS) experienced prolonged interruption of their rehabilitation palliative care routines due to restrictive COVID-19 pandemic public health measures. This study assesses the effects of before and after the lockdown on functionality rates and quality of life (QoL) in patients with ALS. A longitudinal observational study was conducted. Participants were assessed three times - early January (T0), before mandatory lockdown (T1), and during lockdown (T2) - using the ALS Functional Rating Scale-revised (ALSFRS-R), Fatigue Severity Scale (FSS), and the ALS-Specific Quality of Life-Short Form (ALSSQOL-SF). The paired-sample t-test and Wilcoxon signed-rank test were used. Thirty-two patients were included with a mean age of 56.9 (SD 14.2) years and mean symptoms onset of 27.1 (SD 14.3) months. ALSFRS-R mean scores decayed significantly over time when comparing T0-T1 (0.26 ± 0.38) and T1-T2 (1.36 ± 1.43) slopes (p < 0.001). Significant differences were observed between T1 and T2 for ALSSQOL-SF scores (115.31 ± 17.06 vs. 104.31 ± 20.65), especially in four specific domains, and FSS scores (34.06 ± 16.84 vs. 40.09 ± 17.63). Negative correlations between negative emotions and physical symptoms assessed by ALSSQOL-SF and FSS were found. Rehabilitation treatment routines in palliative care, such as physiotherapy and speech therapy, appear to mitigate the ALSFRS-R slope. Prolonged interruption of rehabilitation during the lockdown may have accelerated the functional decline in ALS patients' motor skills with as measured after 2 months by the ALSFRS-R in the limb and bulbar subscores, but not respiratory subscore. Other short-term effects, increased fatigue and negative impact on QoL, were also verified.

Levels of Apelin-12, AT1R, and AGT are correlated with degree of renal fibrosis in patients with immunoglobulin A nephropathy.

To explore the relationship between the degree of renal fibrosis in patients with immunoglobulin A nephropathy (IgAN) and their levels of Apelin-12, Average Optical Density of angiotensin II type 1 receptor (AODAT1R), and angiotensinogen (AGT). A total of 156 patients with IgAN diagnosed by renal biopsy in our hospital were selected and divided into a T0 group (54 cases), T1 group (49 cases) and T2 group (53 cases). The levels of Apelin-12, AT1R, and AGT were compared among the three groups, and the relationship between the above three indicators and degree of renal fibrosis was analyzed among patients with IgAN. The AODAT1R and AGT level in the T2 group and T1 groups were significantly higher than those of the T0 group, and the Apelin-12 level of patients in the T2 group and T1 groups were significantly lower than that in T0 group. Significances of the same trend were observed among all the above indicators between the T2 group and T1 group. ROC curves showed that when the cutoff value of Apelin-12 was 2.36 µg/L, the area under curve (AUC), sensitivity, and specificity of T0-T1T2 were 0.889, 92.00%, and 88.00%, respectively. When the cut-off value of AODAT1R was 0.065, the AUC, sensitivity, and specificity were 0.706, 76.00%, and 76.00%, respectively, and when the cut-off value of AGT was 47.26 ng/mL, the AUC, sensitivity, and specificity were 0.899, 84.00%, and 88.00%, respectively. When the cutoff value of Apelin-12 was 0.92 µg/L, the AUC, sensitivity, and specificity of T0T1-T2 were 0.819, 84.62%, and 87.50%, respectively, and when the cutoff value of AODAT1R was 0.079, the AUC, sensitivity, and specificity were 0.699, 76.92%, and 79.17%, respectively. When the cut-off value of AGT was 92.96 ng/mL, the AUC, sensitivity, and specificity were 0.893, 84.62%, and 91.67%, respectively. Apelin-12 decreased with disease progression, while AT1R and AGT increased. The changes of levels of Apelin-12, AT1R, and AGT have certain significance in judging the degree of renal fibrosis in patients with IgA nephropathy, and the change of level of AGT has the highest correlation with the degree of renal fibrosis.

The psychological impact of COVID-19 and lockdown measures among a sample of italian patients with eating disorders: A longitudinal study

IntroductionCOVID-19 pandemic and lockdown greatly impact on mental health, especially on individuals with pre-existing psychiatric conditions.ObjectivesTo explore the prevalence of specific psychiatric symptoms across a sample of patients with Eating Disorder (ED), compared to a group of healthy controls (HC), during the lockdown period in Italy, and to assess whether patients’ symptoms improved, persisted or worsened with the easing of the lockdown measures.MethodsStudy 1: 59 ED patients and 43 HC were recruited and completed, at the beginning of May 2020(t0), an online survey including: the Depression, Anxiety and Stress Scale – 21 items (DASS-21), the Impact of Event Scale-Revised (IES-R), the Perceived Stress Scale (PSS), and few ad-hoc questions extracted from the Eating Disorder Examination Questionnaire (EDE-Q). Study 2: 40 ED patients from Study 1 completed the same survey two months after t0 (t1).ResultsStudy 1: ED patients scored significantly higher than HC at the DASS-21 (Total Score and subscales), the IES-R (Total Score and subscales) and the PSS. Moreover, they showed higher distress specifically related to food and their body. Study 2: at t1, levels of stress, anxiety and depression were not different than at t0, but symptoms related to post-traumatic stress disorder (PTSD) improved, together with patients’ reported level of psychological wellbeing and specific ED symptomatology.ConclusionsDuring lockdown, ED patients presented significantly higher levels of stress, anxiety, depression, PTSD-related symptoms, and ED-related symptoms than HC. With the easing of lockdown, PTSD-related and ED-related symptoms ameliorated, but high levels of stress, anxiety and depression persisted.DisclosureNo significant relationships.

Diagnostic Performance of MRI for Esophageal Carcinoma: A Systematic Review and Meta-Analysis.

Background Although CT, endoscopic US, and PET are critical in determining the appropriate management of esophageal carcinoma (squamous cell carcinoma and adenocarcinoma), previous reports show that staging accuracy remains low, particularly for nodal involvement sensitivity. Purpose To perform a systematic review and meta-analysis to determine the diagnostic performance of MRI for multiple staging thresholds in patients with biopsy-proven esophageal carcinoma (differentiation of stage T0 disease from stage T1 or higher disease, differentiation of stage T2 or lower disease from stage T3 or higher disease, and differentiation of stage N0 disease from stage N1 or higher disease [where T refers to tumor stage and N refers to nodal stage]). Materials and Methods Studies of the diagnostic performance of MRI in determining the stage of esophageal carcinoma in patients before esophagectomy and pathologic staging between 2000 and 2019 were searched in PubMed, Scopus, Web of Science, and Cochrane Library by a librarian and radiation oncologist. Pooled diagnostic performance of MRI was calculated with a bivariate random effects model. Bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies (version 2) tool. Results Twenty studies with a total of 984 patients were included in the analysis. Pooled accuracy for stage T0 versus stage T1 or higher had a sensitivity of 92% (95% CI: 82, 96) and a specificity of 67% (95% CI: 51, 81). Pooled accuracy for stage T2 or lower versus stage T3 or higher had a sensitivity of 86% (95% CI: 76, 92) and a specificity of 86% (95% CI: 75, 93). Pooled accuracy for stage N0 versus stage N1 or higher had a sensitivity of 71% (95% CI: 60, 80) and a specificity of 72% (95% CI: 64, 79). The concern for applicability was low for the patient selection, index test, and reference test domains, except for 10% of studies (two of 20) that had unclear concern for patient selection applicability. Conclusion MRI has high sensitivity but low specificity for the detection of esophageal carcinoma, which shows promise for determining neoadjuvant therapy response and for detecting locally advanced disease for potential trimodality therapy. © RSNA, 2021 Online supplemental material is available for this article.

Serial Ultrasonographic and Real-Time Elastosonographic Assessment of the Ovine Common Calcaneal Tendon, after an Experimentally Induced Tendinopathy.

Real-time elastosonography (RTE) is a recently described, non-invasive, ultrasonographic technique developed to assess tissue elasticity. The main aim of this study was to investigate the ultrasonographic and elastosonographic appearance of the common calcaneal tendon (CCT) in an ovine model, and to monitor the progression of tendon healing after an experimentally-induced tendinopathy. Sound tendons were initially evaluated (T0) with a caliper and by a single operator with ultrasound. Ultrasonographic and elastosonographic images were then acquired. Subsequently, ultrasound-guided tendon lesions were induced by injecting 500 IU of Type IA collagenases proximally to the calcaneal tuberosity. Caliper measurement, ultrasonography and elastosonography were then repeated at 15 (T1), 30 (T2) and 60 (T3) days. Clinically measured width of the tendon, ultrasonographic thickness and width and percentage of hard (Elx-t%hrd) and soft (Elx-t%sft) tissue were recorded. Statistical analysis was performed on the data collected; statistical significance was set at p < 0.05. Intra-class correlation coefficient (ICC) revealed good (0.68) repeatability of elastosonographic evaluation of the CCT. The tendon width was significantly increased when comparing T0 with T1–2 and decreased when comparing T1–2 with T3. Ultrasound-assessed thickness was significantly increased between T0–T1 and decreased between T1-T2–3. Elx-t%hrd was significantly decreased at T1–2–3 and Elx-t%sft was significantly increased at T1–2–3. In conclusion, the ovine CCT is a highly stiff structure that undergoes a severe loss of stiffness during the healing process. Thickness and width of the tendon increased during the first 30 days and then reduced progressively along the subsequent 30 days. Ultrasonographic appearance of the tendon remained severely abnormal and the tendon showed severely reduced elastic proprieties 60 days after lesion induction.
