BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R package (BioTIMEr) to facilitate use of the database. Main Types of Variables Included The database is composed of one main data table containing the abundance records and 11 metadata tables. The data are organised in a hierarchy of scales where 11,989,233 records are nested in 1,603,067 sample events, from 553,253 sampling locations, which are nested in 708 studies. A study is defined as a sampling methodology applied to an assemblage for a minimum of 2 years. Spatial Location and Grain Sampling locations in BioTIME are distributed across the planet, including marine, terrestrial and freshwater realms. Spatial grain size and extent vary across studies depending on sampling methodology. We recommend gridding of sampling locations into areas of consistent size. Time Period and Grain The earliest time series in BioTIME start in 1874, and the most recent records are from 2023. Temporal grain and duration vary across studies. We recommend doing sample-level rarefaction to ensure consistent sampling effort through time before calculating any diversity metric. Major Taxa and Level of Measurement The database includes any eukaryotic taxa, with a combined total of 56,400 taxa. Software Format csv and. SQL

Cow's milk allergic children can present sensitisation to probiotics.

AIM: To evaluate sensitivity to different probiotics in children with cow's milk allergy. METHODS: Eighty-five patients (age range: 4 months -12 years) presenting atopic dermatitis (AD) were enrolled. Skin prick test (SPT) responses to three different probiotics preparations (Fiorilac, Dicoflor and Reuterin) were evaluated in addition to relevant food allergens. RESULTS: Thirty-nine patients out of 85 (45.8%) had a positive skin response to prick test for cow's milk (3 with reaction <3 mm). Of the thirty-six patients with a cow's milk weal reaction >3 mm, twenty-eight (77.8%) had a skin response to Fiorilac, four patients (11%) to Dicoflor and four (11%) to Reuterin. The proportion of SPT reaction to all the investigated probiotics preparations was significantly lower than cow's milk (r = 9.406; p = 0.002). A significantly higher sensitization was observed for Fiorilac versus Dicoflor (r = 30.916; p < 0.001) and versus Reuterin (r = 34.133; p < 0.001). CONCLUSION: Probiotic use in patients with cow's milk allergy has to be limited to products that do not contain milk. This should be clearly reported in the label. In selected patients, it is advisable to perform a screening SPT with the product to evaluate its potential contamination with milk

Anesthesia in children with asthma and rhinitis

The incidence of asthma is increasing worldwide, but morbidity and mortality are decreasing, because of improvements in medical care. Although the incidence of severe perioperative bronchospasm is relatively low in asthmatics undergoing anaesthesia, when it does occur it may be life-threatening. Preoperative assessment of asthma should include a specialized medical hystory and physical examination as well as pulmonary function testing. Potential trigger agents should be identified and avoided. In many asthmatic patients treatment with systemic corticosteroids and bronchodilators is indicated to prevent the inflammation and bronchocostriction associated with endotracheal intubation. Nonetheless, acute bronchospasm can still occur, especially at induction and emergence, and should be promptly and methodically managed

Clinical modifications induced by drugs during the perioperative period

Total intravenous anesthesia (TIVA) can be defined as a technique in which general anesthesia is induced and maintained using only intravenous agents. TIVA has become more popular in recent times because of the pharmacokinetic and pharmacodynamic properties of propofol, the availability of short acting synthetic opioids, and the development of delivery systems. Significant differences in anatomy and physiology in adults and children and special needs of younger patients have important consequences on many aspects of anesthesia. Airway and respiratory complications are the most common causes of morbidity during general anesthesia in children. Knowledge of the functional anatomy of airways in children forms the basis in the understanding of the pathological conditions that may occur

16 years follow-up evaluation of immediate vs delayed vs. combined hormonal therapy on fertility of patients with cryptorchidism. Results of a longitudinal cohort study

Background: To investigate in a longitudinal cohort study, the best treatment to preserve fertility in cryptorchid subjects. Patients treated with immediate hormonal vs. delayed vs. combined (hormone plus surgery) therapy consecutively enrolled during the period 1987–1997, were evaluated. Methods: Two hundred fifty-five subjects were enrolled and 192 patients completed the follow-upt. One hundred fifty-six patients and 36 out 192 had monolateral and bilateral cryptorchidism, respectively. Twenty-nine out of 192 were previously treated by surgery alone (Group A), 93/192 by hormone therapy alone (Group B), 51/192 received sequential combined hormone therapy plus surgery (Group C) whilst 19/192 refused any type of treatment (Group D). The other 63 patients were considered lost to follow-up. All the patients underwent medical consultation, scrotal ultrasound scan, sperm analysis and Inhibin B, Follicular Stimulating Hormone (FSH) and Testosterone (T) serum level determination. Results: Testicular volume was found decreased in the Group D patients whilst hormone serum levels were comparable in all groups. Statistically significant differences for sperm characteristics were found in patients treated with hormonal therapy alone or combined with surgery (Groups B and C). These two groups reported better semen quality than patients who received surgery alone or no treatment. No differences were observed between monolateral and bilateral cryptorchidism patients. Conclusions: Early prolonged hormonal therapy is advisable in all patients with cryptorchidism independently from the surgical option of promoting testicular descent to the scrotum. Hormonal therapy provides in our study better chance to obtain adequate sperm quality in adult life

Product innovation and informal market competition in sub-Saharan Africa

The interaction between formal and informal businesses continues to grow in African countries. Yet, competition from informal enterprises remains one of the top three obstacles formal businesses face in sub-Saharan Africa. This paper investigates the effect of informal competition on the performance of innovative products introduced by formal firms. We combine the World Bank's Enterprise Survey with the Innovation Follow-up Survey for five sub-Saharan African countries, and construct two indicators of informal competition, one regional (local)-specific and the other one industry-specific. We find that local informal competition has a robust negative effect on product innovation intensity of formal firms, while within industry informal competition enhances innovative sales. However, larger firms are less affected by local informal competition and actually get a boost in innovative sales from informal competition. We argue that local informal competition harms the performance of product innovation, but only for formal firms that lack strategic collaborative 'footholds' in the informal economy
