Sample size determination is essential for reliable hypothesis testing in clinical trials and should rely on adequate sample size calculations with alpha, beta, variance, and an effect size being the minimal clinically important difference (MCID). This facilitates interpretation of the clinical relevance of statistically significant results. No gold standard for MCIDs exists in postoperative pain research.

We searched Cochrane Central Register of Controlled Trials, MEDLINE, and Embase for English language articles on randomised trials investigating analgesic interventions after total hip or knee arthroplasty. Primary outcomes were the reported MCIDs for pain score and cumulated rescue opioid consumption. Secondary outcomes included reported sample size calculations and propensity to report statistical significance without reaching MCID. Trend analyses were conducted using statistical process control.

We included 570 trials. Median MCID for 0-24 h opioid consumption was 10 mg i.v.

On 30 January 2020, the World Health Organization (WHO) classified it as a pandemic. To examine the psychological effects on dental care providers in China in the midst of the COVID-19 outbreak and factors closely associated with those effects, we conducted a cross-sectional study online with 4 widely used self-administered questionnaires the Patient Health Questionnaire-9, the General Anxiety Disorder-7, the Perceived Stress Scale-10, and the Acute Stress Disorder Scale. Univariate and multivariate analyses were performed to evaluate the variables that potentially affected the mental health of emergency dental care providers. As a result, 969 out of 1035 questionnaires were included in the analysis, with 642 respondents reporting more than 1 symptom (66.3%). The symptom of perceived stress was reported by the largest proportion of the respondents (66.2%, n = 641), and anxiety the least (7.1%, n = 69). After adjustment for confounders, it was found that dental practitioners with preexisting physical health conditions were at higher risk of depression (odds ratio [OR], 1.972; 95% CI, 1.128-3.448; P = .017), and perceived stress (odds ratio, 2.397 95% CI, 1.283-4.478; P = .006). Additionally, feelings of fear, helplessness, or terror resulting from the possibility of contracting COVID-19 were significantly associated with the prevalence of all the 4 psychological symptoms observed (P less then .05). In the present study, we found that dental care providers suffered psychological depression, stress, anxiety, and posttraumatic stress disorder (PTSD) during COVID-19, which indicates the importance of psychological support at times of major epidemic outbreaks.

School-based interventions can establish positive behaviours that reduce the likelihood of oral diseases later in life. The Brush Day & Night (BDN) programme is a 21-day school-based educational programme to promote good oral health behaviours. This study aims to evaluate the effect of the BDN programme on oral health knowledge and behaviour outcomes in children after the intervention as compared to a control group over 24 weeks.

This was a superiority cluster randomised trial of children aged 6-12 years from Indonesia (N = 2021) and Nigeria (N = 750). All children were provided with toothpaste and a toothbrush, and the intervention groups (N = 1107 and 439, respectively) received the 21-day BDN programme. Children were followed up at Weeks 3, 8, and 24 after the programme start date and completed a questionnaire addressing the objectives at all timepoints. Improvement in oral health knowledge and behaviour was calculated based on the percentage of positive change in answers and analysed based on a conditional logistic approach for each evaluation timepoint, compared with control, with a 95% CI.

After 24 weeks, Indonesian children following the BDN programme presented with a 30% and 60% additional probability, respectively, of adequate timing of toothbrushing and of being aware of the importance of adequate toothbrushing frequency compared with control. In Nigeria, after 24 weeks, children following the BDN programme had a 92% and 73% higher probability of adequate toothbrushing frequency and of using fluoride toothpaste, respectively, compared with control.

The BDN programme is effective at improving children's knowledge and behaviour compared with a control population.

Poor oral hygiene can have an adverse effect on quality of life. School-based interventions can establish positive behaviours that reduce the likelihood of dental caries later in life. The Brush Day & Night programme aims to encourage good oral health behaviour and improve oral health and quality-of-life outcomes. In this article, we report the effect of the programme on well-being and oral hygiene measured by plaque levels at 3, 8, and 24 weeks and dental caries at 24 weeks after programme start date.

This was a superiority cluster randomised trial of children 6-12 years of age from Indonesia (N = 2021) and Nigeria (N = 2104). All children were provided with toothpaste and a toothbrush. Children in the intervention group received the 21-day Brush Day & Night programme, whereas those in the control group did not. Children completed a questionnaire addressing the objectives at all time points. Their oral hygiene was assessed using the Oral Hygiene Index-Simplified (OHI-S). link2 Additionally, at baseline and 24 weeks their caries status was recorded using the decayed, missing, and filled teeth (DMFT) index.

In Indonesia, after participation in the programme children demonstrated a 45% increased probability of no worsening in the occurrence of decayed, missing, or filled teeth. In Nigeria, children had a 71% higher probability of having confidence in their smile and the proportion of children with good oral hygiene doubled from 40% to 80% at 24 weeks.

The Brush Day & Night programme was successful in improving well-being and oral hygiene in children in Nigeria and reduced the likelihood of worsening in the occurrence of decayed, missing, or filled teeth in children in Indonesia.

Colon cancer in children and young adults is rare. We sought to compare outcomes and survival between patients ≤and>25 years of age with colon cancer.

Using the National Cancer Database, patients with colon cancer between 2004 and 2016 were identified. We included patients with histological codes consistent with invasive colon adenocarcinoma and excluded those missing data about treatment. Post-surgical outcomes and survival were compared.

Of 531,462 patients meeting criteria, 947 were ≤25 years. Patients ≤25 had more advanced disease (stage III44.4%vs33.4%, stage IV27.5%vs.15.3%) and higher rates of total colectomy (8.9%vs.2.7%) and proctocolectomy (5.0%vs.0.0%) than those >25 years. Stage for stage, 5-year survival was higher in patients ≤25 than those >25years. On multivariate regression, age was not associated with increased risk of mortality while male sex and uninsured status were.

Despite presenting with more advanced disease, patients ≤25 years with colon cancer had better survival than those >25 years.

25 years.Due to the degradation and loss of its natural habitat, the presence of capybaras in urban environments and crop areas has been frequently reported in various regions of Brazil. link3 The objective of this study was to identify the parasitic fauna of free-living capybaras in two impacted biomes of the northeastern region (Atlantic Forest and Caatinga), as well as to evaluate the impact of parasitism on the health of these rodents. For this, ticks, fecal and blood samples (for hematology and serum biochemistry evaluation) were collected from 23 free-ranging capybaras from four areas of Atlantic Forest (areas 1, 2 and 3) and Caatinga (area 4) biomes. Of the 23 animals with parasites, 73.9% (17/23) were parasitized simultaneously by gastrointestinal parasites (GIP) (Strongylida, Strongyloides chapini, Capillaria sp., Trematoda and Eimeria sp.) and Amblyomma ticks (larvae of Amblyomma sp. - areas 1, 2, and 3; Amblyomma dubitatum - areas 1 and 2; A. sculptum - areas 3 and 4), while 26.1% (6/23) were parasitized exclusivresence of A. sculptum evidences the need for studies about the infection by Rickettsia on capybaras and their ticks, to provide data on the potential risk of occurrence of Brazilian Spotted Fever in Pernambuco state, within a One Health perspective.Toxoplasma gondii, an obligatory intracellular protozoan parasite infecting warm-blooded animals, can cause toxoplasmosis, a major zoonosis. A male neutered, domestic cat was referred to the Hebrew University Veterinary Teaching Hospital due to dyspnea after long term treatment with cyclosporine for obsessive self-grooming and pruritis. After thorough diagnostics, including non - invasive imaging, broncho-alveolar lavage, blood serology, hematology and biochemistry, and evaluation of the aspirated fluid components, a severe pneumonia and abdominal effusion were detected with observation of free tachyzoites under light microscopy from lavage fluids. PCR and DNA sequencing of broncho-alveolar lavage was positive for T. gondii. Despite aggressive treatment with antibiotics, oxygen supplementation and T. gondii specific antimicrobials, the cat died. It is suggested that potential candidates for cyclosporine be screened for T. gondii antibodies, kept entirely indoors and not fed uncooked meat in order to prevent exposure to T. gondii infection.Feline heartworm disease is a vector-borne parasitical disease caused by Dirofilaria immitis. Heartworm infection in dogs is prevalent in the Mediterranean countries. Information about the geographical distribution and epidemiological features of D. immitis infection in cats is scarce, particularly in urban stray cats that live within endemic regions for canine heartworm disease. The aim of the current study was to determine the seroprevalence of antigen and antibodies to D. immitis in feral cats in Zaragoza city, an endemic region of Spain. For this purpose, blood samples were examined for microfilariae using a direct blood smear technique and the modified Knott test. Two serological techniques for anti-D. immitis antibody detection (Solo Step® FH and in-house ELISA) and three different commercial antigen tests (DiroChek®, MegaELISA® DIRO Antigen and FASTest® HW) were performed. Blood samples from 250 stray cats were tested 61 cats (24.40%) tested positive by the in-house ELISA, and 9 cats gave positive (3.6%) results with Solo Step® FH. The global seroprevalence of D. immitis in the feline population of the studied area of Zaragoza was 25.20% (63/250) including Solo Step® FH result and in-house ELISA. The blood exam for all samples was negative when evaluating for microfilariae and not a single cat was positive for antigen testing. This study demonstrates the presence of D. immitis infection in Zaragoza city. Veterinarians working in endemic areas should be aware of this infection in cats at risk and their susceptibility.
