The experience of the rigid lockdown in the dental emergency room and urgency care during COVID-19 pandemic: a transnational multicenter observational study.

OBJECTIVE: The COVID-19 pandemic had a major impact on our lives all over the world. Changes have occurred in daily life as well as in all medical services. The aim of the present study was to evaluate the emergency accesses in four universities' emergency services during the lockdown period from March to June 2020 during the COVID-19 pandemic. SUBJECTS AND METHODS: A cross-sectional study was carried out on 44,787 patients to evaluate the emergency services of university centers. The medical data of Medical Emergency Service Data (MESD) were assessed by five independent operators considering the epidemiological findings for statistics methods. RESULTS: A lower level of emergency access was reported in March-July compared to the pre-COVID period. The epidemiological data confirmed that female pathologies were more frequent compared to male patients. A fluctuation for almost all urgent healthcare centers was detected, showing one/two peaks per year during the years 2017-2019. The COVID-19 pandemic period did not influence the variety of pathology detected. CONCLUSIONS: After the lockdown period, the emergency services slowly increased in cases. The pre-COVID period showed an overlapping of the most frequent pathologies compared to the post-COVID period: periodontitis (Bari and Tirana), dental fractures (Bari and Bucharest), odontogenic abscess (Bari, Cluj and Tirana).

Autologous tooth for bone regeneration: dimensional examination of Tooth Transformer® granules.

OBJECTIVE: Since 1967, when the osteoinduction properties of autogenous demineralized dentin matrix were discovered, autologous tooth grafts have been advocated as a viable option to autologous or heterologous bone graft. Tooth graft materials may be extracted from the patient's whole tooth using a granulating device. The aim of this study was to examine the size of granules obtained by the Tooth Transformer (TT)® device, using a laser instrument with high precision. MATERIALS AND METHODS: The TT® device can obtain bone graft material in a short period from an extracted tooth. The resulting material can act as an osteoconductive scaffold, providing a mineral substrate during resorption, including platelet growth factors and morphogenetic proteins. Different studies have investigated the dimension and behavior of various graft material particles, since the size of the grafted particles may play a role in osteogenesis and bone regeneration. RESULTS: Different dimensions of granules are available: small (< 400 µm), medium (400 µm-1,000 µm) and large (1,000 µm-2,000 µm). From 4.03 µm to 100 µm the percentage of granules was 14.52 ± 1.93%. A larger part of the granules was up to 100 µm, while 85.47 ± 1.93% of the granules were from 100 µm to 1,000 µm. CONCLUSIONS: 85% of the granules produced were in accordance with the dimensions suggested in the literature.

Soft tissue regeneration in animal models using grafts from adipose mesenchymal stem cells and peripheral blood fibrin gel.

OBJECTIVE: Our study aimed to evaluate the effect of soft tissue regeneration in nude mice using grafts made from the combination of adipocytes from fat tissue mesenchymal stem cells and fibrin gel from peripheral blood. MATERIALS AND METHODS: Mesenchymal stem cells were isolated from adipose tissue and identified according to ISCT criteria. The scaffold used was fibrin obtained from peripheral blood. The grafts in this study were generated by transferring mesenchymal stem cells onto a fibrin scaffold. Two types of grafts, the research sample (fibrin scaffold containing adipocytes differentiated from mesenchymal stem cells) and the control sample (fibrin scaffold only), were grafted under the dorsal skin of the same mouse. After each research period, samples were collected and evaluated by histological methods to observe the existence and growth of cells inside the grafts. RESULTS: The results showed that the study group's graft integrated better within the tissue when compared with the control group. In addition, the grafts in the study group showed the presence of cells with characteristic morphology of adipocytes one week after transplantation. In contrast, control samples showed dimorphous shapes and features mainly composed of non-homogenous fragments. CONCLUSIONS: These initial conclusions might be considered a first step in generating safe bio-compatible engineered grafts specifically usable in post-traumatic tissue regeneration procedures.

Outcomes of endoscopic full thickness resection in the colon rectum at an Italian tertiary center.

PURPOSE: Endoscopic full-thickness resection (EFTR) is an innovative technique for the treatment of colonic lesions not feasible by conventional endoscopic resection. Here, we aimed to evaluate the efficacy and safety of a Full-Thickness Resection Device (FTRD) for colonic lesions in a high-volume tertiary referral center. METHODS: A review of a prospectively collected database on patients that underwent EFTR with FTRD for colonic lesions from June 2016 to January 2021 at our institution was performed. Data regarding the clinical history, previous endoscopic treatments, pathological examination, technical and histological success, and follow-up were evaluated. RESULTS: Thirty-five patients (26 males, median age 69 years) underwent FTRD for colonic lesion. Eighteen lesions were in the left colon, three in the transverse, and 12 in the right colon. The median size of the lesions was 13 (range 10-40) mm. Resection was technically successful in 94% of patients. The mean hospital stay was 3.2 (SD ± 1.2) days. Adverse events were reported in four cases (11.4%). Histological complete resection (R0) was achieved in 93.9% of cases. Endoscopic follow-up was available in 96.8% of patients, at a median duration of 14.6 months (3-46 months). Recurrence was observed in 19.4% of cases at a median time of 3 months (3-7 months). Five patients had multiple FTRD performed, with R0 resection in three cases. In this subset, adverse events were observed in 40% of cases. CONCLUSIONS: FTRD is safe and feasible for standard indication. The non-negligible rate of recurrence observed suggests the need for close endoscopic follow-up in these patients. Multiple EFTR could help achieve complete resection in selected cases; however, in this setting, a higher risk of adverse events was observed.

Non-thyroidal illness syndrome in chronic diseases: role of irisin as modulator of antioxidants.

OBJECTIVE: Non-thyroidal-illness syndrome (NTIS) refers to condition found in chronic diseases that is an adaptive mechanism. However, oxidative stress is related to NTIS in a vicious circle, due to deiodinases alteration and negative effects of low T3 on antioxidant levels or activity. Muscle is one of the main targets of thyroid hormones and it can secrete a myokine named irisin, which is able to induce the browning of white adipose tissue, energy expenditure and protect against insulin resistance. Inconclusive data have been reported about irisin role in chronic diseases. Moreover, no correlation with antioxidants has been investigated. Therefore, we performed a case-control study with the primary endpoint to evaluate irisin levels in two models of NTIS, such as chronic heart failure (CHF) and chronic kidney disease (CKD) during haemodialytic treatment. The secondary endpoint was the correlation with total antioxidant capacity (TAC) to establish a possible role of irisin in the modulation of antioxidant systems. PATIENTS AND METHODS: Three groups of subjects were enrolled. Group A included CHF patients (n=18; aged 70.22 ± 2.78 ys; BMI ± 27.75 ± 1.28 kg/m2); Group B included CKD patients (n=29; aged 67.03 ± 2.64; BMI 24.53 ± 1.01); finally, 11 normal subjects (Group C) have been enrolled as controls. Irisin has been evaluated by ELISA method and Total Antioxidant Capacity (TAC) by spectrophotometric method. RESULTS: Irisin was significantly higher in Group B vs. A and C groups (Mean ± SEM: 20.18 ± 0.61 ng/ml vs. 2.77 ± 0.77 and 13.06 ± 0.56, respectively; p<0.05); a significant correlation between irisin and TAC was observed in group B. CONCLUSIONS: These preliminary data suggest a possible role of irisin in the modulation of antioxidants in two chronic syndromes with low T3 (i.e., CHF and CKD) with differential pattern in these two models studied. Further insights are needed to confirm this pilot study, which could be the basis for a longitudinal investigation, to assess a prognostic role of irisin with possible therapeutic implications.

High-performance Fe(Se,Te) films on chemical CeO2-based buffer layers.

The fabrication of a Fe-based coated conductor (CC) becomes possible when Fe(Se,Te) is grown as an epitaxial film on a metallic oriented substrate. Thanks to the material's low structural anisotropy, less strict requirements on the template microstructure allow for the design of a simplified CC architecture with respect to the REBCO multi-layered layout. This design, though, still requires a buffer layer to promote the oriented growth of the superconducting film and avoid diffusion from the metallic template. In this work, Fe(Se,Te) films are grown on chemically-deposited, CeO2-based buffer layers via pulsed laser deposition, and excellent properties are obtained when a Fe(Se,Te) seed layer is used. Among all the employed characterization techniques, transmission electron microscopy proved essential to determine the actual effect of the seed layer on the final film properties. Also, systematic investigation of the full current transport properties J(θ, H, T) is carried out: Fe(Se,Te) samples are obtained with sharp superconducting transitions around 16 K and critical current densities exceeding 1 MA cm-2 at 4.2 K in self-field. The in-field and angular behavior of the sample are in line with data from the literature. These results are the demonstration of the feasibility of a Fe-based CC, with all the relative advantages concerning process simplification and cost reduction.

Increased levels of plasma neudesin in adult growth hormone deficiency and their relationship with plasma liver-expressed antimicrobial peptide-2 levels: a cross-sectional study.

PURPOSE: Adult growth hormone deficiency (aGHD) is characterized by an altered metabolic profile and increased cardiovascular risk. Neudesin is a newly discovered protein mainly secreted from adipose tissue and brain, under evaluation for its possible activity as a negative regulator of energy expenditure. Liver-expressed antimicrobial peptide (LEAP)-2 is a competitive antagonist of ghrelin on its receptor. An observational cross-sectional study was performed to test the hypothesis that plasma neudesin levels may be modified in aGHD. Given the role played in the energy balance, any possible relationships between neudesin, LEAP-2 and metabolic and anthropometric parameters were evaluated. SUBJECTS AND METHODS: Thirty-eight patients were included: 18 aGHD patients (7 females and 11 males, aged 59.7 ± 2.6 years, BMI 30.2 ± 2.2 kg/m2); 20 healthy controls (12 females and 8 males, aged 47.1 ± 2.5 years, BMI 24.1 ± 0.9 kg/m2). All patients were evaluated for glucose, insulin, HOMA and QUICKI index, total/LDL/HDL cholesterol, triglycerides, uric acid, and IGF-1. Plasma neudesin, LEAP-2, and ghrelin were measured by ELISA. Fat mass was evaluated by DEXA. RESULTS: Neudesin levels were significantly higher in aGHD versus controls. We confirmed the finding of significantly lower ghrelin levels and significantly higher LEAP-2/ghrelin ratio in aGHD patients and found a significant direct correlation between neudesin and LEAP-2 levels. A significant direct correlation between neudesin and fat mass percentage was found in the whole population. CONCLUSION: These results suggest the onset of adaptive responses to an altered metabolic picture in aGHD. The changes in two distinct pathways that modulate food intake and the still limited knowledge about neudesin suggest future developments in this field.

Exploring the Role of Traumatic Event Exposure in Tobacco Dependence Treatment Outcomes Among African Americans.

African Americans are more likely to die from tobacco-related diseases and less likely to quit smoking than their white counterparts. Evidence of greater prevalence of posttraumatic stress disorder (PTSD) among African Americans underscores the importance of studying the effects of traumatic event exposure on tobacco dependence treatment outcomes in this group. In this secondary analysis of data from a previously completed randomized control trial, we examined the effects of traumatic event exposure (e.g., serious accident) on tobacco dependence treatment outcomes, as well its moderating effects on the effectiveness of an adapted smoking cessation treatment, in a sample (n = 169) of African American smokers in New York City. Traumatic event exposure did not have a significant impact on tobacco treatment outcomes and did not moderate the relationship between treatment type and outcomes in this sample. While results may be driven by unique sample characteristics, they may also indicate that an average level of traumatic event exposure does not significantly impact tobacco treatment outcomes among African Americans. Future research should examine the effects of higher levels of traumatic event exposure on treatment outcomes, as well as investigating the factors underlying trauma-exposed individuals' difficulties with reducing/quitting smoking in a larger, more diverse African American sample.

Evaluation of immunoglobulins subclasses and free-light chains in non-obese patients with polycystic ovary syndrome and correlations with hormonal and metabolic parameters: preliminary data.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism and hyperinsulinemia that contribute to create a state of chronic low-grade inflammation. We performed an observational case-control study to investigate inflammatory and immunological parameters, such as IgG subclasses and free light chains (FLCs) and hemolytic complement activity (CH50) in non-obese PCOS, evaluating their relations with metabolic and hormonal parameters. PATIENTS AND METHODS: 36 subjects were studied: 16 PCOS patients (mean±SEM 27.13±1.82 age; BMI 24.1±0.9 kg/m2); 20 controls (aged 26.05±0.73; BMI 20.8 ± 0.4 kg/m2). The blood sample was collected for metabolic and hormonal parameters, IgG subclasses, k and λ FLCs, CH50. Hormones were measured by immunochemiluminometric assays; metabolic parameters by enzymatic assays; subclasses of IgG, FLCs, and CH50 were evaluated by the turbidimetric method. RESULTS: PCOS patients showed vs. controls lower IgG1, IgG2, IgG3 (mean±SEM 3.76±0.29 g/l, 2.63±0.20, 0.62±0.06, 0.34±0.08 vs. 6.49±0.35, 4.28±0.25, 0.84±0.07, 0.33±0.04, respectively) and higher levels of FLCs (k 12.22±0.71 vs. 6.03±0.30, λ 10.10±0.79 vs. 8.04±0.48 g/l) and CH50 (48.64±2.65 vs. 36.51±1.38 U/ml); we found correlation between IgG2 and free-testosterone (r=0.72, p=0.005) and CH50 and vitamin D (r=0.54, p=0.04); an inverse correlation was found between IgG1 and, respectively, ACTH (r=-0.57, p=0.02) and cortisol (r=0.78, p=0.001) in PCOS. CONCLUSIONS: In the complex scenario of low-grade inflammation in non-obese PCOS, we showed lower levels of main subclasses of IgG and higher CH50 levels, suggesting the involvement of other mechanisms other than the "classical" pathway of complement activation; FLCs could be attractive to monitor inflammation degree, disease activity and influence on hormonal status.

Regular football training down-regulates miR-1303 muscle expression in veterans.

PURPOSE: Regular exercise affects the expression of several genes, proteins and microRNAs (miRNAs) in time- and intensity-dependent manner promoting longevity. We previously identified from GeneChip Array analysis several differentially expressed genes and miRNAs in muscle from veteran football players (VPG) compared to active untrained elderly subjects (CG); here we focussed on miRNA-1303 (miR-1303). The aims of the present research were: to analyse the effects of football training on the expression of miR-1303 and to identify its putative target involved in the longevity pathways in skeletal muscle from VPG compared to CG. METHODS: RNA samples from 12 VPG and 12 CG muscle biopsies were used to validate miR-1303 expression. Crossing four different bioinformatic algorithms, we identified 16 putative targets of miR-1303; from these, BAG-2, KLHL7 and KBTBD6 were chosen for further validation by Western blot analysis in LHCN-M2 human myoblasts transiently transfected with miR-1303. RESULTS: Football training down-regulates miR-1303 expression in muscle from VPG compared to CG and the expression of BAG-2, a chaperon protein involved in the autophagy pathway, inversely correlated to overexpression of miR-1303 in a time-dependent manner, indicating that it is a miR-1303 potential target. CONCLUSIONS: This is the first report, to our knowledge, describing miR-1303 regulation in skeletal muscle by football training and the identification of a target protein, BAG-2, involved in the autophagy pathway. This result contributes to the enlargement of knowledge on the molecular mechanisms linking football training, autophagy and longevity.

Evaluation of Kisspeptin levels in prepubertal obese and overweight children: sexual dimorphism and modulation of antioxidant levels.

OBJECTIVE: Kisspeptin, neuropeptide involved in puberty beginning and regulation of pituitary-gonadal axis, has been shown to stimulate antioxidant defenses in murine models. Its levels are greater in females than males and also in obese prepubertal girls. Therefore, our aim was to evaluate sex-related differences in prepubertal obese patients and the relationships of Kisspeptin with metabolic/hormonal parameters. PATIENTS AND METHODS: We studied Kisspeptin concentrations in 54 children (22 males and 32 females, Tanner stage 1), 5-12 ys, classified according to Cole's criteria into 17 overweight and 37 obese; 25 normal-weight children, aged 6-12 years, were studied as controls. We evaluated metabolic (glucose and insulin levels after oral glucose load, total- LDL- HDL-cholesterol, triglycerides, uric acid) and hormonal (fT3, fT4, TSH, IGF-1, leptin) parameters. Moreover, total antioxidant capacity (TAC) was evaluated by spectrophotometric method, using the system H202-metmyoglobin-ABTS. Kisspeptin levels were measured by RIA. RESULTS: We did not find significant differences between obese and normal-weight children, but obese males presented significantly lower levels than females. Kisspeptin did not correlate with BMI, HOMA-IR, Insulin peak levels and TAC; a significant correlation was found between Kisspeptin and fT3 (r2=0.25; p=0.003) in the obese group; leptin levels, significantly greater in obese vs. overweight and control children, significantly correlated with TAC (r2=0.39; p=0.03). CONCLUSIONS: These data suggest that both hormones could modulate antioxidants, Kisspeptin indirectly via influence on thyroid hormones, and Leptin by a direct effect. This mechanism seems to be sex-related, not attributable to peripheral steroid levels. Further studies can clarify the complex interrelationship between central and peripheral Kisspeptin secretion and oxidative stress in children obesity.

Fe(II) interaction with cement phases: Method development, wet chemical studies and X-ray absorption spectroscopy.

Fe(II) interaction with cement phases was studied by means of co-precipitation and sorption experiments in combination with X-ray absorption fine structure (XAFS) spectroscopy. Oxidation of Fe(II) was fast in alkaline conditions and therefore, a methodology was developed which allowed Fe(II) to be stabilised in the sorption experiments and to prepare samples for spectroscopy. X-ray diffraction (XRD) of the co-precipitation samples showed uptake of a small portion of Fe(II) by calcium-silicate-hydrates (C-S-H) in the interlayer indicated by an increase in the interlayer spacing. Fe(II) incorporation by AFm phases was not indicated. Wet chemical experiments using 55Fe radiotracer revealed linear sorption of Fe(II) irrespective of the Ca/Si ratio of C-S-H and equilibrium pH. The Kd values for Fe(II) sorption on C-S-H are more than three orders of magnitude lower as compared to Fe(III), while they are comparable to those of other bivalent metal cations. XAFS spectroscopy showed Fe(II) binding by C-S-H in an octahedral coordination environment. The large number of neighbouring atoms rules out the formation of a single surface-bound Fe(II) species. Instead the data suggest presence of Fe(II) in a structurally bound entity. The data from XRD and XAFS spectroscopy suggests the presence of both surface- and interlayer-bound Fe(II) species.

A French National Study on Gastropleural and Gastrobronchial Fistulas After Bariatric Surgery: the Impact of Therapeutic Strategy on Healing.

PURPOSE: Gastropleural and gastrobronchial fistulas (GPF/GBFs) are serious but rare complications after bariatric surgery whose management is not consensual. The aim was to establish a cohort and evaluate different clinical presentations and therapeutic options. MATERIALS AND METHODS: A multicenter and retrospective study analyzing GPF/GBFs after bariatric surgery in France between 2007 and 2018, via a questionnaire sent to digestive and thoracic surgery departments. RESULTS: The study included 24 patients from 9 surgical departments after initial bariatric surgery (21 sleeve gastrectomies; 3 gastric bypass) for morbid obesity (mean BMI = 42 ± 8 kg/m2). The GPF/GBFs occurred, on average, 124 days after bariatric surgery, complicating an initial post-operative gastric fistula (POGF) in 66% of cases. Endoscopic digestive treatment was performed in 79% of cases (n = 19) associated in 25% of cases (n = 6) with thoracic endoscopy. Surgical treatment was performed in 83% of cases (n = 20): thoracic surgery (n = 5), digestive surgery (n = 8), and combined surgery (n = 7). No patient died. Overall morbidity was 42%. The overall success rate of the initial and secondary strategies was 58.5% and 90%, respectively. The average healing time was approximately 7 months. Patients who had undergone thoracic surgery (n = 12) had more initial management failures (n = 9/12) than patients who had not (n = 3/12), p = 0.001. CONCLUSION: Complex and life-threatening fistulas that are revealed late require a multidisciplinary strategy. Thoracic surgery should be reserved once the abdominal leak heals; otherwise, it is associated with a higher risk of failure.

Recurrent hepatocellular carcinoma and non-classic adreno-genital syndrome.

OBJECTIVE: Hepatocellular carcinoma (HCC) is one of the most common fatal cancer in the world and androgens are among the possible etiological factors. Congenital adrenal hyperplasia (CAH) is a group of inherited diseases caused by enzyme failure in the steroid biosynthesis of the adrenal cortex, resulting in an augmented 17-hydroxyprogesterone, androstenedione and testosterone production. While the occurrence of testicular adrenal rest tumors and adrenocortical tumors in congenital adrenal hyperplasia is well described in the literature, no data on HCC occurrence are available. CASE PRESENTATION: A 35-years-old Italian man of Caucasian origin, affected by non-classic CAH due to partial 21-hydroxylase deficiency came to observation for revaluation of his adrenal picture. Besides common hormonal and biochemical analysis, an abdomen Magnetic Resonance Imaging was performed, resulting in an 18 mm large nodular lesion between liver segments VII and VIII. Radiological reports matched with an increased serum α-fetoprotein level. A surgical removal of the lesion was performed. After that, several recurrences of the lesion, which was consequently treated by radiofrequency ablation, occurred. Every recurrence was accompanied by an increase in testosterone and steroid hormone binding globulin serum levels. CONCLUSIONS: Our report suggests the need for screening of liver lesions in males affected by this syndrome.

Pigmented purpuric dermatosis in children: a retrospective cohort with emphasis on treatment and outcomes.

BACKGROUND: Data regarding the course and treatment of pigmented purpuric dermatoses (PPD) in the paediatric population are limited. Although treatments for pigmented purpura are not well established, vitamin C and rutoside have been reported to be an effective treatment option and are widely utilized. OBJECTIVE: To assess the clinical course and utility of vitamin C and rutoside in paediatric patients with PPD treated at Ann & Robert H. Lurie Children's Hospital of Chicago between 2008 and 2018. METHODS: A retrospective review of all children with PPD managed at our hospital between 2008 and 2018 was performed. Additional follow-up was obtained via telephone interviews. RESULTS: A total of 101 patients met inclusion criteria. The female: male ratio was 1.3 : 1, and the median age at diagnosis was 8.8 years (IQR, 5.7-12.9). Median follow-up was 7.13 months (IQR, 3-17.4). The most common PPD subtypes were lichen aureus (43%) and Schamberg (34%). Fifty-three (52%) patients had evaluable follow-up documentation via their medical record or phone questionnaire. Twenty-eight patients were treated with vitamin C or rutoside or combination therapy. Twenty-five patients received no treatment. Clearance of the rash was noted in 24 (45.3%) patients overall, including 10 (42%) patients in the treated group and 14 (58%) patients in the untreated group. Recurrence was noted in seven (13.2%) patients. Treatment with vitamin C and/or rutoside was well tolerated without side effects. None of the patients were subsequently diagnosed with vasculitis, coagulopathy or cutaneous T-cell lymphoma. CONCLUSION: Pigmented purpuric dermatosis in children is a benign disorder with high rates of complete resolution. Treatment with vitamin C and rutoside is well tolerated, but in this cohort, there did not appear to be an advantage over watchful waiting without therapy.

Development of a validated short-form of the Childhood Atopic Dermatitis Impact Scale, the CADIS-SF15.

BACKGROUND: The Childhood Atopic Dermatitis Impact Scale (CADIS) with 45 items may be burdensome to complete. We therefore aimed to develop a CADIS short-form. METHODS: Parents of 300 children completed the prototype CADIS. Exploratory factor analysis was conducted on the 45-item CADIS version. The most representative items were chosen. Confirmatory factor analysis was used to confirm the a priori factor structure. Content validity was assessed in a focus group of patients, parents, clinicians, methodologists and industry delegates. Internal consistency, 48-h test-retest reliability, construct validity and responsiveness of the newly developed short-form were assessed. RESULTS: A total of 270 families provided data at baseline, 34 after 48 h and 228 after 4 weeks. Fourteen items of three different factors fulfilled the proposed eligibility criteria and were included in the draft short-form. After the content validity rating, one item relating to the child's sleep was added to further improve content validity. The confirmatory factor analyses showed good model fit, and a 15-item short-form was initiated, the CADIS-SF15. The total scale and the three domains showed good internal consistency and test-retest reliability. The correlation between SCORAD and other subjective measures was consistent with our hypotheses. Differences in scores between mild, moderate and severe AD patients were significant, and the CADIS-SF15 was able to detect changes in 'improving' patients over time. CONCLUSION: The CADIS-SF15 with 15 items in three domains is an internally consistent, reliable, valid, responsive and brief measure of QoL in children affected with AD and their parents. Further evaluation of clinical applicability is required.

Hormonal deficiencies in heart failure with preserved ejection fraction: prevalence and impact on diastolic dysfunction: a pilot study.

OBJECTIVE: In heart failure with reduced ejection fraction, catabolic mechanisms have a strong negative impact on mortality and morbidity. The relationship between anabolic hormonal deficiency, thyroid function, and heart failure with preserved ejection fraction (HFpEF) has still been poorly investigated. Therefore, we aimed to define the multi-hormonal deficiency prevalence in HFpEF patients and the relationships between hormonal deficiency and echocardiographic indexes. PATIENTS AND METHODS: Plasma levels of N-terminal pro-brain natriuretic peptide, fasting glucose, thyroid-stimulating hormone, free triiodothyronine (T3), free thyroxine, insulin-like growth factor-1, dehydroepiandrosterone-sulfate (DHEA-S), total testosterone (only in male subjects) in 40 patients with HFpEF were evaluated. An echocardiographic evaluation was performed. RESULTS: One (2.5%) patient (2.5%) had no hormonal deficiencies; 8 (20%) patients had deficits of one hormone, 18 patients (45%) of two axes, 12 patients (30%) of three axes, and one patient (2.5%) of all four axes. Among them, 97.5% had DHEA-S deficiency, 67.5% IGF-1 deficiency, 37% testosterone deficiency, 22.5% a "Low T3 syndrome", and 20% subclinical hypothyroidism. Patients with IGF-1 deficit showed higher left atrial volume values, systolic pulmonary artery pressure (SPAP), tricuspid peak velocity (TPV), and lower tricuspid annular plane systolic excursion (TAPSE) and TAPSE/SPAP ratio values. Patients with testosterone deficiency had higher SPAP and TPV. Patients with low T3 syndrome had higher value of right ventricular mid cavity diameter. Hormonal dysfunction was independent from the presence of comorbidities and no difference between male and female subjects was noted. CONCLUSIONS: Multi-hormonal deficiencies are associated with right ventricular dysfunction and diastolic dysfunction in patients with HFpEF.

Goni Moreno progressive preoperative pneumoperitoneum for giant hernias: a monocentric retrospective study of 162 patients.

INTRODUCTION: Goni Moreno's procedure was described 60 years ago as a solution for giant hernias repair through the creation of a progressive preoperative pneumoperitoneum (PPP). The main objective of the present study is to assess its effectiveness in terms of primary fascial closures. The secondary objectives of this study are to explore the morbidity and mortality associated with Moreno's procedure using 40 years of data from a large cohort of patients. MATERIALS AND METHODS: This is a retrospective study of all patients who underwent PPP procedures between October 1974 and January 2019 at the digestive surgery unit at Grenoble University Hospital, France. Data were reviewed to assess the preoperative demographic characteristics of the patients, procedure, postoperative course, complication following Clavien-Dindo classification and 30-day outcomes. RESULTS: 162 procedures were attempted. The mean age of patients was 57.8 years. 83 patients had a history of chronic respiratory disease (51.2%). The mean BMI was 33.2 kg/m2, and 52 patients were obese (32.1%) Half of the patients were classified as ASA score III. Success rate of fascial closures was 95.7%. The global rate of complication during the insufflation period and after surgical repair of the hernia was 51.8% (n = 84). Among these, only 16.7% (n = 27) were major according to the Clavien-Dindo classification. The global mortality rate was 3.1%. CONCLUSION: Goni Moreno PPP is an effective procedure that allows a high rate of fascial closure. The population of patients requiring such procedures presents a high-risk profile for complications regarding demographics and associated diseases.

Evaluation of responsiveness and estimation of smallest detectable change and minimal important change scores for the Childhood Atopic Dermatitis Impact Scale.

BACKGROUND: The Childhood Atopic Dermatitis Impact Scale (CADIS) is an instrument to measure quality of life in young children affected by atopic dermatitis, and their parents. OBJECTIVES: To evaluate the responsiveness (sensitivity to change), smallest detectable change (SDC) and minimal important change (MIC) of the CADIS. METHODS: Parents and primary caregivers of 300 young children completed the CADIS and a global rating of their child's skin condition at baseline and a 4-week follow-up. Kruskal-Wallis tests, Wilcoxon tests and effect sizes were used to assess responsiveness. The SDC can be seen as a change beyond measurement error. Anchor-based and distribution-based methods, and an integration of both methods were used to estimate the MIC. RESULTS: In total, 270 families provided data at baseline and 228 at follow-up. The CADIS total change score and most of the domain scores had moderate-to-strong correlations with the skin change score. Patients were grouped according to the skin change score, which served as an anchor. Children whose parents noted an improvement of the skin showed lower CADIS scores at follow-up (P < 0·001). For the SDC we obtained score changes of 1·34 points on the total score and < 1·0 points on each domain score. All detected MIC values passed the SDC cut-off. CONCLUSIONS: The CADIS is sensitive to change towards improvement of quality of life. A change > 12% on the total score or each domain score very likely represents a clinically important change. What's already known about this topic? Atopic dermatitis reduces the quality of life of affected children and their parents. The Childhood Atopic Dermatitis Impact Scale (CADIS) has been evaluated and translated into two further languages. What does this study add? Further validation of the responsiveness of the CADIS, and whether it is sensitive to change in patients whose condition had changed. Calculation of the smallest detectable change. What are the clinical implications of this work? Estimation of the minimal important change in CADIS provides benchmarks for clinical practice.
