Relationship among Milk Conductivity, Production Traits, and Somatic Cell Score in the Italian Mediterranean Buffalo

The measurement of milk electrical conductivity (EC) is a relatively simple and inexpensive technique that has been evaluated as a routine method for the diagnosis of mastitis in dairy farms. The aim of this study was to obtain further knowledge on relationships between EC, production traits and somatic cell count (SCC) in Italian Mediterranean Buffalo. The original dataset included 5411 records collected from 808 buffalo cows. Two mixed models were used to evaluate both the effect of EC on MY, PP and FP and EC at test-day, and the effect of EC on somatic cell score (SCS) by using five different parameters (EC_param), namely: EC collected at the official milk recording test day (EC_day0), EC collected 3 days before official milk recording (EC_day3), and three statistics calculated from EC collected 1, 3 and 5 days before each test-day, respectively. All effects included in the model were significant for all traits, with the only exception of the effect of EC nested within parity for FP. The relationship between EC and SCS was always positive, but of different magnitude according to the parity. The regression of EC on SCS at test-day using different EC parameters was always significant except when the regression parameter was the slope obtained from a linear regression of EC collected over the 5-day period. Moreover, in order to evaluate how well the different models fit the data, three parameters were used: the Average Information Criteria (AIC), the marginal R2 and the conditional R2. According to AIC and to both the Marginal and Conditional R2, the best results were obtained when the regression parameter was the mean EC estimated over the 5-day period

A family nurse-led intervention for reducing health services’ utilization in individuals with chronic diseases : The ADVICE pilot study

Objectives Intensive health services’ utilization is common in older individuals affected by chronic diseases. This study assessed whether a structured family nurse-led educational intervention would be effective in reducing health services’ use (readmissions and/or emergency service access) among older people affected by chronic conditions. Methods This is a non-randomized before-after pilot study. A sample of 78 patients was recruited from two general practices in Italy and 70 among them were followed for 8 months. Standard home care was provided during the first four months’ period (months 1–4), followed by the educational intervention until the end of the study (months 5–8). The intervention, based on the teach-back method, consisted of by-weekly 60-min home sessions targeting aspects of the disease and its treatment, potential complications, medication adherence, and health behaviours. Rates of health services’ use were collected immediately before (T0), and after the interventions (T1). Differences in utilization rates were examined by the McNemar’s test. Potential factors associated with the risk of health services’ use were explored with a Cox proportional hazard regression model. Results The sample (n = 78) was predominantly female (n = 50, 64.1%), and had a mean age of 76.2 (SD = 4.8) years. Diabetes mellitus was the most frequent disease (n = 27, 34.6%). McNemar’s test indicated a significant reduction in health services’ use at T1 (McNemar χ2 = 28.03, P < 0.001). Cox regressions indicated that time and patient education, as well as their interaction, were the only variables positively associated with the probability of health services’ use. Conclusion A teach-back intervention led by a family nurse practitioner has the potential to reduce health services’ use in older patients with chronic diseases

Efficacy and Safety of Neem Oil for the Topical Treatment of Bloodsucking Lice Linognathus stenopsis in Goats under Field Conditions

: The aim of the present study was to evaluate the efficacy and safety of neem oil on caprine pediculosis and on kids' growth performances. The neem (Azadirachta indica) belongs to the Meliaceae family, and in Eastern countries it is mainly considered for the insecticidal activities of the kernel oil. The neem seeds contain bioactive principles, such as azadirachtin A, salannin, nimbin, and nimbolide. The trial was carried out on 24 kids, 120 days old, maintained in open yards. Animals were divided in 4 homogeneous groups (n = 6 animals/group) based on age, louse count, body condition score (BCS) and live body weight: Control Group (C, saline NaCl, 0.9%), Neem Group 1 (NO-100, 100 mL of neem oil per 10 kg), Neem Group 2 (NO-200, 200 mL/10 kg), Neem Group 3 (NO-300, 300 mL/10 kg). The treatments were performed by spraying the insecticide on the goat's body. The study lasted 56 days, and weekly, the kids underwent louse count, BCS and body weight determination, and FAMACHA score. Data were analyzed by ANOVA for repeated measures. The species of lice identified was Linognathus stenopsis. Kids belonging to NO-200 and NO-300 showed a stronger reduction of louse count throughout the study (>95%). The daily weight gain recorded was significantly higher (p < 0.05) in NO-300 than C. No differences were found for BCS and FAMACHA scores. The results of this trial showed that the administration of neem oil to control caprine pediculosis caused by sucking lice represents an alternative to synthetic compounds

PLURIPARIDADE NAS ÉGUAS: RELAÇÃO COM CARACTERÍSTICAS MATERNAS, PLACENTÁRIAS E NEONATAIS

A placenta é o órgão de ligação entre a égua e o potro e é um dos principais responsáveis pelo desenvolvimento fetal e pelas características morfométricas do neonato. Essa função se torna cada vez mais importante porque os estudos indicam que as características físicas dos potros predizem o seu desenvolvimento na vida adulta. Desta forma, o objetivo do presente estudo foi correlacionar número de partos (1-5) e características maternas de éguas com as características placentárias e o tamanho do potro. As éguas foram categorizadas em grupos de acordo com o número de partos sendo G1: 1 parto (n=4); G2: 2 partos (n=6); G3: 3 partos (n=7); G4: 4 partos (n=5); e G5: 5 partos (n=3). Como principais resultados obtidos, o perímetro torácico e o peso da égua pré- e pós-parto influenciaram positivamente peso (p=0,004/ R= 0,51; p=0,002/ R= 0,55; p=0,01/ R= 0,43), altura (p=0,0005/ R= 0,60; p=0,001/ R= 0,57; p=0,005/ R= 0,50) e perímetro torácico (p=0,0001/ R= 0,65; p?0,0001/ R= 0,71; p=0,0002/ R= 0,64) dos potros ao nascimento. Éguas com maior peso corporal no pré-parto apresentaram maior peso placentário (p=0,01/R= 0,45) e pariram potros mais pesados (p=0,003/ R= 0,52) com maior perímetro torácico (p=0,01/ R= 0,45). Os neonatos de éguas do G4 foram os mais pesados, indicando que provavelmente o maior tamanho uterino em éguas pluríparas permita uma maior cobertura placentária, maior área de contato materno fetal e provavelmente maior aporte de nutrientes ao feto.

The developmental effects of media-ideal internalization and self-objectification processes on adolescents’ negative body-feelings, dietary restraint, and binge eating

Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., “internalizers” and “self-objectifiers”), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one’s body from an external observer’s standpoint (or self-objectification), which then predicted later negative emotional experiences related to one’s body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents’ feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed

Acute Delta Hepatitis in Italy spanning three decades (1991–2019): Evidence for the effectiveness of the hepatitis B vaccination campaign

Updated incidence data of acute Delta virus hepatitis (HDV) are lacking worldwide. Our aim was to evaluate incidence of and risk factors for acute HDV in Italy after the introduction of the compulsory vaccination against hepatitis B virus (HBV) in 1991. Data were obtained from the National Surveillance System of acute viral hepatitis (SEIEVA). Independent predictors of HDV were assessed by logistic-regression analysis. The incidence of acute HDV per 1-million population declined from 3.2 cases in 1987 to 0.04 in 2019, parallel to that of acute HBV per 100,000 from 10.0 to 0.39 cases during the same period. The median age of cases increased from 27 years in the decade 1991-1999 to 44 years in the decade 2010-2019 (p &lt; .001). Over the same period, the male/female ratio decreased from 3.8 to 2.1, the proportion of coinfections increased from 55% to 75% (p = .003) and that of HBsAg positive acute hepatitis tested for by IgM anti-HDV linearly decreased from 50.1% to 34.1% (p &lt; .001). People born abroad accounted for 24.6% of cases in 2004-2010 and 32.1% in 2011-2019. In the period 2010-2019, risky sexual behaviour (O.R. 4.2; 95%CI: 1.4-12.8) was the sole independent predictor of acute HDV; conversely intravenous drug use was no longer associated (O.R. 1.25; 95%CI: 0.15-10.22) with this. In conclusion, HBV vaccination was an effective measure to control acute HDV. Intravenous drug use is no longer an efficient mode of HDV spread. Testing for IgM-anti HDV is a grey area requiring alert. Acute HDV in foreigners should be monitored in the years to come

Investigation of Climate Effects on the Physiological Parameters of Dairy Livestock (Cow vs. Buffalo)

Nowadays climate change is affecting the planet’s biodiversity, and livestock practices must adapt themselves to improve production without affecting animal welfare. This work investigates the influence that some climatic parameters such as Environment Temperature, Relative Humidity, Thermal excursion and Temperature–Humidity Index (THI), can have on milk quantity and quality in two different dairy species (buffaloes and cows) raised on the same farm. A further aim was to understand if THI threshold used for cows could also be used for buffaloes. The climatic parameters were recorded daily through a meteorological station located inside the farm. Milk quantity (converted into ECM) and quality (Fat Percentage—FP; Protein Percentage—PP; Somatic Cell Count—SCC) were measured. Data were analyzed with Spearman’s correlation index, separately for buffaloes and cows. The results indicate a greater sensitivity of cows to heat stress and a strong negative correlation of the ECM with meteorological data (p < 0.01). The results of this study may stimulate the use of integrated technologies (sensors, software) in the dairy sector, since the IoT (sensors, software) helps to enhance animal well-being and to optimize process costs, with a precision livestock farming approach

Editorial: Influence of diet and maternal environment on neuropsychological development early in life

The prenatal and perinatal environment, along with the eating habits of early life, may shape the neuropsychological developmental trajectories of infants and future adolescents (1). Epidemiology shows that the number of people worldwide featuring neurodevelopmental disorders (NDDs), which include ADHD, autism, learning disabilities, intellectual disabilities, and behavioral disorders, has increased over the past decade (2). Taking action on modifiable factors could have far-reaching effects on public health practice and policy development. Data from a recent meta-analysis (3) found a median prevalence per 1,000 people for any NDD of 7.6 (95%CI 7.5–7.7), 11.3 (11.7–12.0) for neurological disorders, and 3.2 (95%CI 3.1–3.3) for mental conditions such as ADHD. In this context, this Research Topic aimed to add knowledge to the understanding of the composite network of direct and indirect environmental effects on the neuropsychological health of children and adolescents. The baseline assumption is that different and complex environmental dimensions, including maternal environment, physical and chemical environment (e.g., from exposure to specific pollutants to exposure to multiple and possibly interacting substances) (4–6), socioeconomic environment (e.g., education, social support, stress, work environment, and access to health care), and living environment (e.g., maternal and fetal diet, housing conditions, green space, and exposure to noise and light) (1, 7) are among the modifiable factors within the exposome still under study
