The Effect of a Physical Activity Program on the Total Number of Primary Care Visits in Inactive Patients: A 15-Month Randomized Controlled Trial
Abstract
Background: Effective promotion of exercise could result in substantial savings in healthcare cost expenses in terms of
direct medical costs, such as the number of medical appointments. However, this is hampered by our limited knowledge of
how to achieve sustained increases in physical activity.
Objectives: To assess the effectiveness of a Primary Health Care (PHC) based physical activity program in reducing the total
number of visits to the healthcare center among inactive patients, over a 15-month period.
Research Design: Randomized controlled trial.
Subjects: Three hundred and sixty-two (n = 362) inactive patients suffering from at least one chronic condition were
included. One hundred and eighty-three patients (n = 183; mean (SD); 68.3 (8.8) years; 118 women) were randomly allocated
to the physical activity program (IG). One hundred and seventy-nine patients (n = 179; 67.2 (9.1) years; 106 women) were
allocated to the control group (CG). The IG went through a three-month standardized physical activity program led by
physical activity specialists and linked to community resources.
Measures: The total number of medical appointments to the PHC, during twelve months before and after the program, was
registered. Self-reported health status (SF-12 version 2) was assessed at baseline (month 0), at the end of the intervention
(month 3), and at 12 months follow-up after the end of the intervention (month 15).
Results: The IG had a significantly reduced number of visits during the 12 months after the intervention: 14.8 (8.5). The CG
remained about the same: 18.2 (11.1) (P = .002).
Conclusions: Our findings indicate that a 3-month physical activity program linked to community resources is a shortduration,
effective and sustainable intervention in inactive patients to decrease rates of PHC visits.

Histological and immunohistochemical features suggesting aetiological differences in lymph node and (muco)cutaneous feline tuberculosis lesions
Objectives To identify and describe histological and immunohistochemical criteria that may differentiate between skin and lymph node lesions associated with Mycobacterium (M.) bovis and M. microti in a diagnostic pathology setting.Materials and Methods<jats:p/>Archived skin and lymph node biopsies of tuberculous lesions were stained with haematoxylin and eosin, ZiehlâNeelsen and Masson's Trichrome. Immunohistochemistry was performed to detect the expression of calprotectin, CD3 and Pax5. Samples were scored for histological parameters (i.e. granulomas with central necrosis versus small granulomas without central necrosis, percentage necrosis and/or multinucleated giant cells), number of acidâfast bacilli (bacterial index) and lesion percentage of fibrosis and positive immunohistochemical staining.Results Twentyâtwo samples were examined (M. bovis n=11, M. microti n=11). When controlling for age, gender and tissue, feline M. bovisâassociated lesions more often featured large multiâlayered granulomas with central necrosis. Conversely, this presentation was infrequent in feline M. microtiâassociated lesions, where small granulomas without central necrosis predominated. The presence of an outer fibrous capsule was variable in both groups, as was the bacterial index. There were no differences in intralesional expression of immunohistochemical markers.Clinical Significance Differences in the histological appearance of skin and lymph node lesions may help to infer feline infection with either M. bovis or M. microti at an earlier stage when investigating these cases, informing clinicians of the potential zoonotic risk. Importantly, cases of tuberculosis can present with numerous acidâfast bacilli. This implies that a high bacterial index does not infer infection with nonâzoonotic nonâtuberculous mycobacteria
Impact of biological agents on postsurgical complications in inflammatory bowel disease: A multicentre study of Geteccu
Background: The impact of biologics on the risk of postoperative complications (PC) in inflammatory bowel disease (IBD) is still an ongoing debate. This lack of evidence is more relevant for ustekinumab and vedolizumab. Aims: To evaluate the impact of biologics on the risk of PC. Methods: A retrospective study was performed in 37 centres. Patients treated with biologics within 12 weeks before surgery were considered âexposedâ. The impact of the exposure on the risk of 30-day PC and the risk of infections was assessed by logistic regression and propensity score-matched analysis. Results: A total of 1535 surgeries were performed on 1370 patients. Of them, 711 surgeries were conducted in the exposed cohort (584 anti-TNF, 58 vedolizumab and 69 ustekinumab). In the multivariate analysis, male gender (OR: 1.5; 95% CI: 1.2â2.0), urgent surgery (OR: 1.6; 95% CI: 1.2â2.2), laparotomy approach (OR: 1.5; 95% CI: 1.1â1.9) and severe anaemia (OR: 1.8; 95% CI: 1.3â2.6) had higher risk of PC, while academic hospitals had significantly lower risk. Exposure to biologics (either anti-TNF, vedolizumab or ustekinumab) did not increase the risk of PC (OR: 1.2; 95% CI: 0.97â1.58), although it could be a risk factor for postoperative infections (OR 1.5; 95% CI: 1.03â2.27). Conclusions: Preoperative administration of biologics does not seem to be a risk factor for overall PC, although it may be so for postoperative infections
Early life risk factors and their cumulative effects as predictors of overweight in Spanish children
Objectives: To explore early life risk factors of overweight/obesity at age 6 years and their cumulative effects on overweight/obesity at ages 2, 4 and 6 years.
Methods: Altogether 1031 Spanish children were evaluated at birth and during a 6-year follow-up. Early life risk factors included: parental overweight/obesity, parental origin/ethnicity, maternal smoking during pregnancy, gestational weight gain, gestational age, birth weight, caesarean section, breastfeeding practices and rapid infant weight gain collected via hospital records. Cumulative effects were assessed by adding up those early risk factors that significantly increased the risk of overweight/obesity. We conducted binary logistic regression models.
Results: Rapid infant weight gain (OR 2.29, 99% CI 1.54â3.42), maternal overweight/obesity (OR 1.93, 99% CI 1.27â2.92), paternal overweight/obesity (OR 2.17, 99% CI 1.44â3.28), Latin American/Roma origin (OR 3.20, 99% CI 1.60â6.39) and smoking during pregnancy (OR 1.61, 99% CI 1.01â2.59) remained significant after adjusting for confounders. A higher number of early life risk factors accumulated was associated with overweight/obesity at age 6 years but not at age 2 and 4 years.
Conclusions: Rapid infant weight gain, parental overweight/obesity, maternal smoking and origin/ethnicity predict childhood overweight/obesity and present cumulative effects. Monitoring children with rapid weight gain and supporting a healthy parental weight are important for childhood obesity prevention
Testing the Efficacy of a Multi-Component DNA-Prime/DNA-Boost Vaccine against Trypanosoma cruzi Infection in Dogs
Immunization of dogs with DNA-prime/DNA-boost vaccine (TcVac1) enhanced the
Trypanosoma cruzi-specific type 1 antibody and
CD8+ T cell responses that resulted in an early control of
acute parasitemia and a moderate decline in pathological symptoms during chronic
phase. Further improvement of vaccine-induced immunity would be required to
achieve clinical and epidemiological benefits and prevent transmission of
parasites from vaccinated/infected dogs to triatomines
Studies of new Higgs boson interactions through nonresonant HH production in the bÂŻbγγ fnal state in pp collisions at âs = 13 TeV with the ATLAS detector
A search for nonresonant Higgs boson pair production in the b
¯bγγ fnal state
is performed using 140 fbâ1 of proton-proton collisions at a centre-of-mass energy of 13 TeV
recorded by the ATLAS detector at the CERN Large Hadron Collider. This analysis supersedes
and expands upon the previous nonresonant ATLAS results in this fnal state based on the
same data sample. The analysis strategy is optimised to probe anomalous values not only of
the Higgs (H) boson self-coupling modifer Îșλ but also of the quartic HHV V (V = W, Z)
coupling modifer Îș2V . No signifcant excess above the expected background from Standard
Model processes is observed. An observed upper limit ”HH < 4.0 is set at 95% confdence
level on the Higgs boson pair production cross-section normalised to its Standard Model
prediction. The 95% confdence intervals for the coupling modifers are â1.4 < Îșλ < 6.9 and
â0.5 < Îș2V < 2.7, assuming all other Higgs boson couplings except the one under study are
fxed to the Standard Model predictions. The results are interpreted in the Standard Model
efective feld theory and Higgs efective feld theory frameworks in terms of constraints on
the couplings of anomalous Higgs boson (self-)interactions
EPIdemiology of Surgery-Associated Acute Kidney Injury (EPIS-AKI) : Study protocol for a multicentre, observational trial
More than 300 million surgical procedures are performed each year. Acute kidney injury (AKI) is a common complication after major surgery and is associated with adverse short-term and long-term outcomes. However, there is a large variation in the incidence of reported AKI rates. The establishment of an accurate epidemiology of surgery-associated AKI is important for healthcare policy, quality initiatives, clinical trials, as well as for improving guidelines. The objective of the Epidemiology of Surgery-associated Acute Kidney Injury (EPIS-AKI) trial is to prospectively evaluate the epidemiology of AKI after major surgery using the latest Kidney Disease: Improving Global Outcomes (KDIGO) consensus definition of AKI. EPIS-AKI is an international prospective, observational, multicentre cohort study including 10 000 patients undergoing major surgery who are subsequently admitted to the ICU or a similar high dependency unit. The primary endpoint is the incidence of AKI within 72 hours after surgery according to the KDIGO criteria. Secondary endpoints include use of renal replacement therapy (RRT), mortality during ICU and hospital stay, length of ICU and hospital stay and major adverse kidney events (combined endpoint consisting of persistent renal dysfunction, RRT and mortality) at day 90. Further, we will evaluate preoperative and intraoperative risk factors affecting the incidence of postoperative AKI. In an add-on analysis, we will assess urinary biomarkers for early detection of AKI. EPIS-AKI has been approved by the leading Ethics Committee of the Medical Council North Rhine-Westphalia, of the Westphalian Wilhelms-University MĂŒnster and the corresponding Ethics Committee at each participating site. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and used to design further AKI-related trials. Trial registration number NCT04165369
Measurement of fiducial and differential W + W - production cross-sections at s = 13 TeV with the ATLAS detector
Abstract: A measurement of fiducial and differential cross-sections for W+W- production in protonâproton collisions at s=13 TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 36.1 fb-1 is presented. Events with one electron and one muon are selected, corresponding to the decay of the diboson system as WWâe±ΜΌâÎœ. To suppress top-quark background, events containing jets with a transverse momentum exceeding 35 GeV are not included in the measurement phase space. The fiducial cross-section, six differential distributions and the cross-section as a function of the jet-veto transverse momentum threshold are measured and compared with several theoretical predictions. Constraints on anomalous electroweak gauge boson self-interactions are also presented in the framework of a dimension-six effective field theory
Early Pleistocene faunivorous hominins were not kleptoparasitic, and this impacted the evolution of human anatomy and socio-ecology
Humans are unique in their diet, physiology and socio-reproductive behavior compared to other primates. They are also unique in the ubiquitous adaptation to all biomes and habitats. From an evolutionary perspective, these trends seem to have started about two million years ago, coinciding with the emergence of encephalization, the reduction of the dental apparatus, the adoption of a fully terrestrial lifestyle, resulting in the emergence of the modern anatomical bauplan, the focalization of certain activities in the landscape, the use of stone tools, and the exit from Africa. It is in this period that clear taphonomic evidence of a switch in diet with respect to Pliocene hominins occurred, with the adoption of carnivory. Until now, the degree of carnivorism in early humans remained controversial. A persistent hypothesis is that hominins acquired meat irregularly (potentially as fallback food) and opportunistically through klepto-foraging. Here, we test this hypothesis and show, in contrast, that the butchery practices of early Pleistocene hominins (unveiled through systematic study of the patterning and intensity of cut marks on their prey) could not have resulted from having frequent secondary access to carcasses. We provide evidence of hominin primary access to animal resources and emphasize the role that meat played in their diets, their ecology and their anatomical evolution, ultimately resulting in the ecologically unrestricted terrestrial adaptation of our species. This has major implications to the evolution of human physiology and potentially for the evolution of the human brain
