Abstract
OBJECTIVE Respiratory diseases present a challenge for the healthcare system due to their prevalence and clinical impact. The aim of this study was to explore the current situation of hospital pharmacy in the field of respiratory diseases. METHOD Observational, cross-sectional study, with a national scope, divided into 2 parts. In an initial phase, the activity and level of pharmaceutical care in respiratory diseases was evaluated through an online questionnaire using REDCap. The survey was addressed to department chiefs and consisted of 17 items, divided into 2 modules: general data and general activity. The second phase was open to hospital pharmacists, with the aim of exploring their opinion on care, training, and improvement needs. The number of items in this phase was 19, divided into 5 modules: general data, pharmaceutical care, competencies, training and degree of satisfaction. RESULTS In the first phase, 23 hospitals were included. Most of them (n=20) had a pharmacist in charge of respiratory diseases. However, a large proportion of them dedicated less than 40% of their working day to this activity. The pharmacist's activity occurred at the level of external patients (n=20), hospitalized patients (n=16), and secondarily in management (n=8). Integration is greater in pathologies such as asthma, IPF, pulmonary hypertension, and bronchiectasis. Participation in committees was present in 15 hospitals, with variability in pathologies and degree of involvement. In the second phase, 164 pharmacists participated, who considered pharmaceutical care in cystic fibrosis, asthma and lung transplant as a priority. Fifty-one percent considered integration to be adequate and 91% considered it necessary to implement prioritization criteria. Professional competencies ranged from 6.5-6.9 out of 10 points. Only 45% of participants had received specific training in the last four years, indicating greater priority for asthma, pulmonary hypertension and IPF. CONCLUSIONS Most centers have pharmacists specialized in respiratory diseases. However, there is room for improvement in terms of sub specialization, participation in multidisciplinary committees, implementation of prioritization criteria, diversification in pathologies treated, as well as greater specific training in this area.

Abstract
Most of the signs and symptoms of heart failure can be explained by fluid overload, which is also related to disease progression. Fluid overload is a complex phenomenon that extends beyond increased intravascular pressures and poses challenges for accurate diagnosis and effective treatment. Current recommendations advise a multiparametric approach, including clinical data (symptoms/signs), imaging tests, and biomarkers. This article proposes a practical therapeutic approach to managing hydrosaline overload in heart failure in both inpatient and outpatient settings. This document is an initiative of the Spanish Society of Internal Medicine (SEMI) in collaboration with the Spanish Society of Cardiology (SEC) and the Spanish Society of Nephrology (S.E.N.).

From micro to mesoscale: Understanding the influence of macroalgal communities on Ostreopsis Schmidt blooms. HARMFUL ALGAE 2024; 136:102650. [PMID: 38876526 DOI: 10.1016/j.hal.2024.102650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 05/08/2024] [Accepted: 05/19/2024] [Indexed: 06/16/2024]
Abstract
Harmful Algal Blooms (HABs) are increasing in temperate areas, and the growth rates of benthic harmful dinoflagellates may be favoured in the context of global climate change. Benthic dinoflagellates, including species belonging to the Ostreopsis Schmidt genus, are known to develop on the surface of macroalgae and different macroalgal morphotypes and communities could host higher or lower cell abundances. The physical structure of the macroalgal substrate at the small scale (cm, microhabitat scale) and the structural complexity of the macroalgal community at the medium scale (few m, mesohabitat scale) could play a relevant role in bloom facilitation: the hypothesis that Ostreopsis species could be associated with macroalgal turfs and shrubs, structurally less complex communities than canopy-forming macroalgae, is especially under discussion and, if confirmed, could link bloom occurrence to regime shifts in temperate ecosystems. The present study, performed in two locations of the Ligurian Sea (Rochambeau, France and Vernazzola, Italy) aimed at understanding marine vegetation's role at the micro and mesohabitat scales in controlling the distribution and abundance of Ostreopsis. The abundance of the microalgal cells was quantified at different spatial scales, from cm to a few m, on different macroalgal species and communities, including artificial substrates, to tease apart the micro and mesohabitat effects. The results obtained show a high spatio-temporal variability, potentially hiding habitat-related patterns. The substrate's preferences diminish when cell abundances are very high, as in the case of Rochambeau, while in presence of moderate cell abundances as in Vernazzola or the first phases of blooms, it is possible to appreciate differences in abundances among substrates (in our study, Dictyota fasciola (Roth) Lamouroux supporting higher abundances). Our results open new research topics such as the study of blooms at a larger scale (macrohabitat) and testing different sampling methods to standardise the cells' abundances independently on the substrate.

Abstract
The study of new indirect methods for mastitis detection is of great relevance both at the economic level of the farm and dairies, and in terms of consumer health, and animal welfare. These methods help us to monitor the disease and speed up the decision-making process on treatment of the affected animal and the destination of the milk. The main aim of this work was to study the effect of intramammary infection and other non-infectious factors on the activity of the enzyme N-acetyl-β-D-glucosaminidase (NAGase) in milk, in order to evaluate its use as an indicator for the early diagnosis of mastitis in sheep that could be less expensive, easier to measure and a better marker of inflammation or complementary to existing methods such as somatic cell count (SCC). Seven biweekly samplings were carried out, in which NAGase activity, SCC and milk were analyzed. Glands were classified according to their sanitary status based on the results of the SCC and bacteriological analysis. Non-infectious factors such as lactation stage, parity number and milking session had a statistically significant effect on NAGase values, finding the highest NAGase values at the onset and end of the study, in infectious mastitic glands of multiparous females and at morning milking. However, among the NAGase variation factors studied, the health status of the gland was the factor that caused the highest variation in enzyme levels, with infectious mastitic glands showing higher values than healthy glands. The predictive ability of NAGase was also studied by means of several logistic regression models, with the one that included NAGase together with lactation stage and parity obtaining the best results if sensitivity is to be prioritized, or the model that included NAGase, lactation stage, parity, milking and production if specificity is to be prioritized. From the results obtained, it can be concluded that the use of NAGase as an intramammary infection detection method in sheep can be useful when non-infectious factors that cause changes in the concentration of the enzyme are also considered.

Abstract
Abstract
Background and significance
Heart Failure (HF) is the leading cause of cardiovascular deaths and ∼50% of HF patients have HF with preserved ejection Fraction (HFpEF). HFpEF patients typically have co-morbidities such as atrial fibrillation (AF), diabetes, lung edema and hypertension. The latter is a predictor of mortality and is targeted to prolong survival given the lack of a direct therapy for HFpEF. To address this unmet public health problem, we investigate the therapeutic potential of the insulin-like hormone Relaxin (RLX) in a rat model of HFpEF that recapitulates most aspects of clinical HFpEF.
Methods
ZSF1 diabetic rats were placed on a high fat diet (HFD for 11-weeks) and echocardiograms were used to track HFpEF development. At week 20, osmotic mini-pumps were implanted to release vehicle (Na-acetate) or RLX (400μg/kg/day, 2-weeks). Hearts were then perfused with a voltage-sensitive dye (RH237) and a Ca2+ indicator (Rhod-2/AM) to optically map action potentials and Ca2+ transients and analyze arrhythmia phenotype. Left ventricular (LV) tissue sections were used for immune-fluorescence (IF) imaging for changes in fibrosis (collagen 1), connexin 43, Wnt1 and β-catenin in LV myocytes. Blood draws were taken to measure changes in serum NT-pro-ANP, ET-1 and RLX.
Results
ZSF1 rats on a HFD developed HFpEF with E/e' (an echo marker of diastolic dysfunction) decreasing to −24.4 from −17.9 MV (n=12) and was reversed to −18.6 MV by RLX (n=6, p<0.0001). In HFpEF rats that received the vehicle (n=6), a premature stimulus (S1-S2= 40 ms) elicited: a) no arrhythmia b) non-sustained AF or c) sustained AF, with (1/3 of rats in each group). RLX blocked sustained supraventricular (n=0/12) and n=4/12 had non-sustained AF. RLX improved conduction velocity (CV), at short cycle lengths (150 ms) from 0.74 to 0.9 m/s (n=4/group). IF indicated that RLX increased Cx43 (26.8±0.03%, p<0.0001, n=6), and β-catenin (52.8±0.05%, p<0.0001) at intercalated disks. RLX reduced collagen deposition in HFpEF rats (25±0.04%, p<0.04, back to normal) and caused a marked increase of cytosolic Wnt1 (47.3±0.06%, p<0.0001). IF data are given as mean ± SEM.
Conclusions
The ZSF1 diabetic rat on a high-fat diet recapitulates most of the phenotypes associated with human HFpEF, including atrial arrhythmias, fibrosis, and lung edema. RLX treatment post-development of HFpEF reversed the pro-arrhythmic phenotype, increased conduction velocity particularly at fast heart rates, reversed fibrosis, reduced NT-pro-ANP and ET-1 in male rats. Most intriguing, RLX treatment activated Wnt1 and β-catenin indicating that the beneficial actions of RLX occur via genomic remodeling of the heart.

Abstract
Leptospirosis is one of the most widely distributed zoonosis in the world. Bovine leptospirosis is a serious problem in bovine production, causing reproductive losses. The aim of this work was to compare recombinant LipL32 with sonicated antigen for detecting anti-Leptospira IgG antibodies in bovine serum using ELISA. The Microscopic Agglutination Test (MAT) is used as the gold standard. Sonicated antigen from cultures of Leptospira interrogans serogroup Icterohaemorrhagiae serovar copenhageni (strain M20) was used for the eELISA and rLipL32 for the rELISA. The performance of these assays was evaluated using serum samples from 166 bovines, 69 MAT positive and 97 MAT negative. At the optimal cut-off point recommended by the receiver operating characteristic (ROC) curve analysis, the sensitivity and specificity values were 98.6% and 97.9%, respectively, for eELISA, and 85.5% and 86.6% respectively, for rELISA. The value for the area under the ROC curve was 0.998 (0.994-1.0) (CI 95%) for eELISA and 0.929 (0.891-0.968) (CI 95%) for rELISA. The ROC curves for rLipL32 and sonicated antigen showed statistically significant differences (z = -3.826; p = 0.000). A three-way comparison showed statistically significant differences in the sensitivity and specificity of rELISA and eELISA. Our results showed that eELISA was more specific and sensitive than rELISA. The difference in performance (eELISA-rELISA) was 13.4% (4.03-23.28) (CI 95%) for sensitivity and 11.34 % (4.07-19.56) (CI 95%) for specificity. Our results show that the eELISA has a better diagnostic performance than rELISA for the detection of anti-Leptospira IgG antibodies in bovine serum.

Abstract
Corrugated cardboard has waved cores with small flutes that prevent the use of detailed numerical models of whole structures. Many homogenization methods in the literature overcome this drawback by defining equivalent homogeneous plates with the same mechanical behaviour at a macro-mechanical scale. However, few homogenization works have considered complete structures, focusing mainly on beams or plates. For the first time, this study explores the application of homogenization approaches to larger structures as an aid in their design process. We also considered triple-wall boards rather than single- and double-wall configurations commonly addressed in the literature. To this end, we adapted the homogenization methods proposed by Talbi and Duong to analyze thin-walled stools made of triple-wall corrugated cardboard. Using a progressive design process, we performed an efficient stool design by removing material zones with lower stresses, with 35% less material, 35% lower vertical deflections, and 66% lower stresses than the initial design. Unlike other corrugated cardboard stools, this design comprises just one folded piece instead of three, thus saving storage space. These results demonstrate the utility of homogenization techniques as an aid in the design process of whole structures made of corrugated cardboard. Further research will consider buckling analysis.

Abstract
Abstract
Background and Aims
Expanded hemodialysis (HDx) improves clearance of middle molecules as a target for uremia treatment. According to previously published results, high cut off filters have high enough clearance to allow diminishing of dialysate flow (Qd) without detrimental in HD adequacy outcomes with less water waste.
According to World Health Organization (WHO), globally, almost 800 million people lack access to safe water and 2.5 billion lack access to optimal sanitation. Is our duty to search for ways to avoid water waste.
Our aim is to describe the differences in water use between HDX patients receiving Qd 400 mL/min (Group 1) vs 500 ml/min (group 2) in HD patients from 10 renal clinics in Colombia as an alternative to reduce water waste in chronic HD as a strategy from Blue Planet Dialysis initiatives.
Method
We performed a Sub-analysis of CORHEX Study: We calculated water use at different Qd from our database: prospective, multicentre, observational cohort study of 992 adult patients undergoing chronic HD from 12 renal clinics in Colombia who were switched from high-flux HD to MCO therapy and observed for 12 months. All patients were prescribed with HDX three times a week for a minimum of 4 hours.
We analysed patients with weight lower than 70 Kg at different Qd prescriptions to calculate water use at different Qd prescriptions and performed a prediction analysis, adjusting to Qd 400 mL/min, the whole potential population with weight lower than 70 Kg.
Results
462 patients with weight lower than 70 Kg were analysed, 127 patients received Qd 400 mL/min.
When diminishing Qd from 500 to 400 mL/min, 24 litres were saved per session per patient without detriment of middle molecule clearance. There were no differences in adequacy HD parameters between Qd prescriptions (Table 1 and 2).
Conclusion
HDX allows lowering of Qd to 400 mL/min without harm for patients and with remarkable savings of potable water: 24 Litres were saved in each session per patient that can be translated in almost 3500 Litres of water each year by patient which is enough for one year for 47 adults. (Based on the WHO minimum for basic health protection of at least 20 L per person/day) (2).
We consider our results especially relevant since the World Health Organization estimates that within the next 5 years, over 50% of world population could reside in geographies lacking sufficient access to water.
We hope that our results from the Blue Planet dialysis research group, alongside with Dr. Agar`s and Dr. Barraclough`s green nephrology initiatives, can help educate the nephrology community on the ecological impact of dialysis and can present an innovative solution to offer HD therapy even in countries suffering from limited access to potable water.

Abstract
Abstract
Background and Aims
B cell targeting agent Rituximab has been proven to be effective and safe for the treatment of idiopathic membranous nephropathy (iMN) in previous studies with nearly 75% achievement of partial or complete remission of nephrotic syndrome. The aim of this study was to evaluate this treatment in a cohort of patients at Complejo Hospitalario de Navarra with relapsing disease.
Method
This is a retrospective, cross sectional study including 12 patients with membranous nephropathy diagnosed by means of a kidney biopsy. All of them were treated before with different immunosuppressive regimens and had a relapse at the time of the inclusion. All of them were treated with two iv infusions of Rituximab. In this study we report patient clinical and immunological baseline characteristics and treatment response at 12 months of follow up.
Results
Between 2015-20 a total of 12 patients (41,6% women and 58,3% men) were treated with two iv infusions of Rituximab with a total mean dose of 2gr. All of them diagnosed previously of iMN, and 10/12 were PLA2r positive. Baseline laboratory data showed serum creatinine levels 1,3±0,9 mg/dl, serum albumin 29±9 g/L, 24 hour- urinary protein excretion of 6,8±3,2 and serum PLA2R levels of 50,54±63,2 RU/ml. Either complete or partial response (CR and PR) were achieved in 83,3% of the cases, however only 3/12 (25%) patients had a complete response at 12 months follow up. All patients who responded had also a significative decrease PLA2r antibodies. Three of the patients who did a PR were treated with an incomplete dose of iv Rituximab (two infusions of 500mg).
Conclusion
Rituximab was effective in our cohort of patients with iMN with achievement of 83,3% response at 12 months of follow up, however only 25% of patients had complete response maybe due to incomplete dosing. Immunological response was seen in all patients. Still, a longer follow up of these patients is needed in order to evaluate Rituximab response.

Abstract
Background and Aims Clinical outcomes of Acute Kidney Injury (AKI) in ICU mainly depend on opportune preventive strategies. Thus, early identification of AKI is mandatory, and alternative diagnostic strategies become plausible: one of them, Renal Angina Index (RAI), described by Matsuura1, predicts the development of AKI KDIGO 2-3, at 7th day after admission to the intensive care unit according to a cut-off point >6 on a scale with a “creatinine score” (determined by the difference in serum creatinine between that at ICU admission and the first 24 hours in the ICU) and the impact of the patients medical history. 1Kidney Int Rep (2018) 3, 677-683. Our aim is to describe predictive capacity of the Renal Angina Index (RAI) in adult critical care patients in our population. Method We retrospectively selected from our Critical Care Nephrology database adult patients admitted in any of our hospital`s ICU between February to August 2020, excluding those at admission with diagnosis of AKI, serum creatinine > 2.5 mg/dl, or those receiving dialysis (acute or chronic) or kidney transplantation. We defined AKI according to KDIGO criteria. The RAI score was defined as the worst condition score multiplied by the creatinine score. The performance of the RAI score was assessed by Receiver Operating Characteristic (ROC) analysis power to detect a difference of 0.2 between the area under the curve (AUC), under the null hypothesis of AUC = 0.5 (no diagnostic accuracy). The optimal cut point was estimated with the Youden method. Results From 1204 new ICU patients, we included 372 patients (women 40.3%), with mean age 60.9 (18-98) (table 1). Main indication for ICU admission was medical conditions. Mean APACHE II was 22.9, hemodinamic support was required in 41,1% patients, mechanical ventilation in 58.6% patients and diabetes mellitus was present in 21.5% patients. AKI KDIGO 2-3 developed in 26.8% of patients. Mean creatinine at admission was statistically different in patients with AKI (CI 0.95 –0.51 - --0.15 mg/dl, p=0.0004). The requirement of hemodynamic (p = 0.003) and ventilatory support (p = 0.009), sepsis (p = 0.003), and COVID-19 (p = 0.03) were more frequent in patients who developed AKI. Renal replacement therapy was required in 39 (60%) of patients with severe AKI (incidence 10,5%). RAI cutt-off point determined by Youden method in the overall sample was 24, being significantly higher in patients who developed AKI (16.54 Vs 7.47, CI 0.95 –13.5--4.99, p <0.001).
A cut-off point of 24 was required for the Best predictive capacity for severe AKI, with sensitivity, specificity, positive and negative likelihood ratio of 34%, 94%, 5.5 and 0.7 respectively. Conclusion In our population, RAI score requires a cutoff point much higher than that originally described to predict the development of severe AKI. Losing its discriminatory capacity.

Abstract
Aspiration thrombectomy is one of the most effective systems for blood clot removal and vessel recanalization. We present the results of a study involving the modelling and extraction of blood clots in the arteries of the human body using the following computer tools: Bond-Graph methodology for the fluid domain and Multi-Body Simulation for the mechanical domain. The modelling for the mechanical domain focuses on the clot and the distal end section of an aspiration device. Our final model considers an elastic characterization of the blood clot with progressive detachment from the vessel wall. We conclude that the results of such modelling could potentially improve the effectiveness of blood clot removal by reducing the risk of clot fragmentation. Such modelling could also potentially provide an adjunct technique in improving recanalization of arteries over a range of given parameters (mechanical properties of the vessel, mechanical properties of the blood clot, blood clot length, suction pressure, catheter - clot distance, catheter shape, catheter diameter and vessel occlusion).

Abstract
Recent research into how the pulsation type affects goat milking concluded that alternate pulsation (AP) and simultaneous pulsation (SP) similarly affect the milking efficiency (milking duration and milking fractioning) and teat end condition after milking when both pulsations are employed in short-term experiments. However, the use of SP in high pipeline milking machines led to higher vacuum fluctuations, which, in the long term, may entail a potential risk factor for the mammary gland health status. The aim of this work was to study how AP and SP affect the milk yield, mammary gland health status, and milk composition of goats in the long term, during a complete lactation period, in a high pipeline milking machine. With this objective, 100 Murciano-Granadina goats with similar parturition dates (4 ± 1 postpartum weeks) were divided into 2 similar groups (50 goats per group) according their parity, milk yield, mammary gland health status, and milking duration (after a 15-d pre-experimental period). Throughout the experimental period (7 mo), one group was milked using SP and the other group using AP. Every month, samplings were carried out of the variables related to sanitary status of the mammary gland, milk fractioning, milking duration, average and maximum milk flows, milk composition, teat end status, vacuum fluctuations at the short milk tube during milking, and pulsation tests. Results showed that the use of SP in a high pipeline milking machine showed higher vacuum fluctuations without involving any difference in the other variables studied. We concluded that the use of AP in the milking of Murciano-Granadina goats offers little improvement of the milking performance and increases the investment required for installation and maintenance of the milking machines.

Abstract
We study quantum state transfer between two qubits coupled to a common quantum bus that is constituted by an ultrastrong coupled light-matter system. By tuning both qubit frequencies on resonance with a forbidden transition in the mediating system, we demonstrate a high-fidelity swap operation even though the quantum bus is thermally populated. We discuss a possible physical implementation in a realistic circuit QED scheme that leads to the multimode Dicke model. This proposal may have applications on hot quantum information processing within the context of ultrastrong coupling regime of light-matter interaction.

Abstract
OBJECTIVES To assess the role of day-care management of upper aerodigestive tract (UADT) panendoscopy and to study criteria for conventional hospital admission and reasons for conversion. PATIENTS AND METHODS Retrospective study, from January 2011 to May 2013. Inclusion criteria UADT panendoscopy for carcinoma assessment. Study variables, age, gender, tumor location, reason for panendoscopy, TNM stage, previous external radiotherapy, home-to-hospital distance and Apfel, Detsky and ASA scores. A day-care and a conventional admission group were compared using Fisher's test for ASA score, student's test for age and Pearson's chi2 test for the other variables. RESULTS Four hundred and thirty-six panendoscopies were performed: 252 in day-care, including 4 cases of conversion and 184 with conventional admission. There were no significant differences between groups for age, gender, tumor location, TNM stage, reason for panendoscopy, previous external radiotherapy, home-to-hospital distance or Apfel score. A significant difference was observed for ASA score (P<0.0001) and Detsky score (P=0.03). In 39% of cases, the reason for hospital admission without criteria defined by the French Society of Anesthesia and Intensive Care Medicine (SFAR) and French Health Authority (HAS) was the patient's refusal of day care. In 10% of conventional admissions, day-care was not implemented because of psychosocial factors. CONCLUSION Day-care management is appropriate for UADT panendoscopy in selected patients. The reasons for the high rate of patient refusal should be studied.

Abstract
BACKGROUND Rituximab (RTX) is increasingly used in the treatment of neuromyelitis optica spectrum disorder (NMO-SD). Administration regimen is not consensual as there is no reliable biomarker of RTX efficacy. In most cases, after induction, RTX is administered systematically every 6months. OBJECTIVE To assess efficacy and safety of a maintenance regimen based on CD19+ CD27+ memory B-cell (mBc) detection. METHODS We conducted a study in two French centers, including patients with NMO-SD who received an induction therapy with RTX. We compared the number of administered infusions, relapses and EDSS depending on two maintenance schemes (S1: administration of 1g RTX infusion every 6months or S2: a scheme based on regular mBc detection. 1g RTX was administered if mBc was >0.05%) RESULTS: 40 patients were included (mean age: 40.2years, F/M sex ratio: 5/1). Aquaporin-4 antibodies were positive in 75% patients. Under S1 regimen, all patients received 2 infusions per year, whereas under S2, they received 1.62 infusion per year. The mean interval between infusions under S2 was 7.4months, without decrease of clinical efficacy. CONCLUSION In our study, mBc-based administration of RTX allowed personalizing treatment administration and in several cases to lower the cumulative dose without loss of efficacy.

Abstract
Measuring the electrical conductivity (EC) of milk during milking has been extensively studied in cattle as a low-cost mastitis detection method that can be easily automated. The aim of this work was to study the effect of the health status of the glands and several noninfectious factors (lactation stage, milking session, and lactation number) that affect the use of EC measurement of milk to detect mastitis in dairy sheep livestock. Likewise, we studied the relation between EC and milk composition (macrocomposition and mineral content) and between EC and somatic cell count (SCC). Finally, we evaluated the use of EC thresholds as a mastitis detection method. To this end, we monitored the glandular milk EC throughout 2 consecutive lactations, during which 42 and 40 ewes were controlled, respectively. We carried out 7 biweekly checks, analyzing the EC, SCC, composition, and mineral content of glandular milk at morning and evening milkings. Before the morning milking, samples were aseptically collected for bacteriological analysis, and the results along with the SCC were used to classify the glands according to their sanitary status (healthy, latently infected, or infected). Lactation stage, parity, milking (morning or evening), health status, and the interactions of parity with health status, lactation stage with health status, and parity with lactation stage all had a significant effect on SCC and EC of the milk. The correlation between EC and SCC was only significant when all the data were analyzed jointly (r = 0.33) and for SCC ≥ 600.000 cells/mL (r = 0.25). The changes in milk composition, mainly in fat content, largely explained the variation in EC (R2 = 0.69). For the same EC threshold, the specificity and sensitivity varied depending on the parity or the milking, with the negative predictive value obtained being higher than the positive predictive value at all times. We concluded that developing methods of detecting mastitis in sheep by milk EC readings would require consideration of noninfectious factors that also affect the gauging of EC. One option to consider would be individualized daily monitoring of the glands, as demonstrated in other species such as cattle and goat.
