RESUMEN

Coronavirus disease 2019 (Covid-19) active cases continue to demand the development of safe and effective treatments. This is the first clinical trial to evaluate the safety and efficacy of oral thymic peptides. ; We conducted a nonrandomized phase 2 trial with a historic control group to evaluate the safety and efficacy of a daily 250-mg oral dose of thymic peptides in the treatment of hospitalized Covid-19 patients. Comparisons based on standard care from registry data were performed after propensity score matching. The primary outcomes were survival, time to recovery, and number of participants with treatment-related adverse events or side effects by day 20. ; A total of 44 patients were analyzed in this study: 22 in the thymic peptide group and 22 in the standard care group. There were no deaths in the intervention group compared to 24% mortality in standard care by day 20 (log-rank P=0.02). Kaplan-Meier analysis showed a significantly shorter time to recovery by day 20 in the thymic peptide group than in the standard care group (median, 6 days vs. 12 days; hazard ratio for recovery, 2.75 [95% confidence interval, 1.34 to 5.62]; log-rank P=0.002). No side effects or adverse events were reported. ; In patients hospitalized with Covid-19, the use of thymic peptides resulted in no side effects, adverse events, or deaths by day 20. Compared with the registry data, a significantly shorter time to recovery and mortality reduction were measured.

RESUMEN

INTRODUCTION AND OBJECTIVES: Wheezing (RW) infants with a positive asthma predictive index (API+) have a lower lung function as measured by forced expiratory techniques. Tidal flow-volume loops (TFVL) are easy to perform in infants, and sedation is not necessary. MATERIALS AND METHODS: A total of 216 wheezing infants were successfully measured, and 183 of them were followed for over a year. TFVL loops were classified into one of three categories depending of their geometric shape (symmetric, convex, and concave). Respiratory rate (Rr), presence of API+, and the number of exacerbations during the following year were also recorded. RESULTS: Children with concave loops had more exacerbations in the following year (OR = 6.8 [IC95% 3.33;13.91]). Infants API + were also significantly more related to concave loops (OR = 10.02 [IC 95% 4.53; 22.15]). Rr was higher in infants with concave loops (44+/-15.5 vs. 36.6 +/-12.6; p < 0.01). CONCLUSION: Infants with a concave TFVL have a higher probability of experiencing exacerbations in the following year, and are at a higher risk of suffering asthma.

RESUMEN

The diagnosis of asthma is currently based on clinical history, physical examination and lung function, and to date, there are no accurate objective tests either to confirm the diagnosis or to discriminate between different types of asthma. This consensus exercise reviews the state of the art in asthma diagnosis to identify opportunities for future investment based on the likelihood of their successful development, potential for widespread adoption and their perceived impact on asthma patients. Using a two-stage e-Delphi process and a summarizing workshop, a group of European asthma experts including health professionals, researchers, people with asthma and industry representatives ranked the potential impact of research investment in each technique or tool for asthma diagnosis and monitoring. After a systematic review of the literature, 21 statements were extracted and were subject of the two-stage Delphi process. Eleven statements were scored 3 or more and were further discussed and ranked in a face-to-face workshop. The three most important diagnostic/predictive tools ranked were as follows: "New biological markers of asthma (eg genomics, proteomics and metabolomics) as a tool for diagnosis and/or monitoring," "Prediction of future asthma in preschool children with reasonable accuracy" and "Tools to measure volatile organic compounds (VOCs) in exhaled breath."

RESUMEN

High-fat diets (HFDs) are an acknowledged risk factor for male subfertility, but the underlying mechanisms remain unclear. In the present study we compared the effects of two HFDs with different ω6:ω3 ratios, one enriched with soy oil (SOD; ω6:ω3=9.62) and another enriched with sunflower oil (SFOD; ω6:ω3=51.55), with those of a commercial diet (CD; ω6:ω3=19.87), supplied from pregnancy to adulthood, on morphometric parameters and reproductive performance in adult male mice (recommended ω6:ω3 for rodents=1-6). Bodyweight was significantly higher in the SFOD than CD group, and relative testicular weight was significantly lower in the SFOD than the other two groups. SFOD altered sperm performance: it reduced sperm viability (mean±s.e.m.; 76.00±1.35% vs 82.50±1.45% and 80.63±1.00% in the SFOD vs CD and SOD groups respectively; P<0.05) and increased the percentage of immature spermatozoa (71.88±7.17% vs 51.38±5.87% and 48.00±5.72% in the SFOD vs CD and SOD groups respectively; P<0.05). The epididymal ω6:ω3 ratio was higher in the SFOD versus CD and SOD groups, whereas the unsaturation index was higher in the SOD and SFOD groups than in CD group. Sperm membrane integrity was diminished in both the SOD and SFOD groups, but there was no difference in sperm reactive oxygen species production in these two groups compared with the CD group. The fertilisation rate was lower in the SFOD compared with the CD and SOD groups. In conclusion, although both HFDs affected sperm quality, the fertilising ability was more altered by the excessive dietary ω6:ω3 ratio than by the net ω6 content.

RESUMEN

BACKGROUND: Our objective was to develop a prognostic stratification tool that enables patients with cancer and pulmonary embolism (PE), whether incidental or symptomatic, to be classified according to the risk of serious complications within 15 days. METHODS: The sample comprised cases from a national registry of pulmonary thromboembolism in patients with cancer (1075 patients from 14 Spanish centres). Diagnosis was incidental in 53.5% of the events in this registry. The Exhaustive CHAID analysis was applied with 10-fold cross-validation to predict development of serious complications following PE diagnosis. RESULTS: About 208 patients (19.3%, 95% confidence interval (CI), 17.1-21.8%) developed a serious complication after PE diagnosis. The 15-day mortality rate was 10.1%, (95% CI, 8.4-12.1%). The decision tree detected six explanatory covariates: Hestia-like clinical decision rule (any risk criterion present vs none), Eastern Cooperative Group performance scale (ECOG-PS; <2 vs ⩾2), O2 saturation (<90 vs ⩾90%), presence of PE-specific symptoms, tumour response (progression, unknown, or not evaluated vs others), and primary tumour resection. Three risk classes were created (low, intermediate, and high risk). The risk of serious complications within 15 days increases according to the group: 1.6, 9.4, 30.6%; P<0.0001. Fifteen-day mortality rates also rise progressively in low-, intermediate-, and high-risk patients: 0.3, 6.1, and 17.1%; P<0.0001. The cross-validated risk estimate is 0.191 (s.e.=0.012). The optimism-corrected area under the receiver operating characteristic curve is 0.779 (95% CI, 0.717-0.840). CONCLUSIONS: We have developed and internally validated a prognostic index to predict serious complications with the potential to impact decision-making in patients with cancer and PE.

RESUMEN

There is a dearth of data from Ecuador on the burden of life-threatening fungal disease entities; therefore, we estimated the burden of serious fungal infections in Ecuador based on the populations at risk and available epidemiological databases and publications. A full literature search was done to identify all epidemiology papers reporting fungal infection rates. WHO, ONU-AIDS, Index Mundi, Global Asthma Report, Globocan, and national data [Instituto Nacional de Estadística y Censos (INEC), Ministerio de Salud Pública (MSP), Sociedad de Lucha Contra el Cáncer (SOLCA), Instituto Nacional de Donación y Trasplante de Órganos, Tejidos y Células (INDOT)] were reviewed. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology by LIFE. Ecuador has a variety of climates from the cold of the Andes through temperate to humid hot weather at the coast and in the Amazon basin. Ecuador has a population of 15,223,680 people and an average life expectancy of 76 years. The median estimate of the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) population at risk for fungal disease (<200 CD4 cell counts) is ∼10,000, with a rate of 11.1% (1100) of histoplasma, 7% (700) of cryptococcal meningitis, and 11% (1070) of Pneumocystis pneumonia. The burden of candidemia is 1037. Recurrent Candida vaginitis (≥4 episodes per year) affects 307,593 women aged 15-50 years. Chronic pulmonary aspergillosis probably affects ∼476 patients following tuberculosis (TB). Invasive aspergillosis is estimated to affect 748 patients (∼5.5/100,000). In addition, allergic bronchopulmonary aspergillosis (ABPA) in asthma and severe asthma with fungal sensitization (SAFS) were estimated to affect 26,642 and 45,013 people, respectively. Our estimates indicate that 433,856 (3%) of the population in Ecuador is affected by serious fungal infection.

RESUMEN

BACKGROUND: This study aimed at estimating the efficiency of palivizumab in the prevention of Respiratory Syncytial Virus (RSV) infection and its sequelae in preterm infants (32day 1-35day 0weeks of gestational age -wGA-) in Spain. METHODS: A decision-tree model was developed to compare health benefits (Quality Adjusted Life Years-QALYs) and costs of palivizumab versus a non-prophylaxis strategy over 6 years. A hypothetical cohort of 1,000 preterm infants, 32day 1-35day 0 wGA (4.356 kg average weight) at the beginning of the prophylaxis (15 mg/kg of palivizumab; 3.88 average number of injections per RSV season) was analysed. The model considered the most recent evidence from Spanish observational and epidemiological studies on RSV infection: the FLIP II study provided hospital admission and Intensive Care Unit (ICU) admission rates; in-hospital mortality rate was drawn from an epidemiological study from 2004 to 2012; recurrent wheezing rates associated to RSV infection from SPRING study were adjusted by the evidence on the palivizumab effect from clinical trials. Quality of life baseline value, number of hospitalized infants and the presence of recurrent wheezing over time were granted to estimate QALYs. National Health Service and societal perspective (included also recurrent wheezing indirect cost) were analysed. Total costs (€, 2016) included pharmaceutical and administration costs, hospitalization costs and recurrent wheezing management annual costs. A discount rate of 3.0% was applied annually for both costs and health outcomes. RESULTS: Over 6 years, the base case analysis showed that palivizumab was associated to an increase of 0.0731 QALYs compared to non-prophylaxis. Total costs were estimated in €2,110.71 (palivizumab) and €671.68 (non-prophylaxis) from the National Health System (NHS) perspective, resulting in an incremental cost utility ratio (ICUR) of €19,697.69/QALYs gained (prophylaxis vs non-prophylaxis). Results derived from the risk-factors population subgroups analysed were in line with the total population results. From the societal perspective, the incremental cost associated to palivizumab decreased to an €1,253.14 (ICUR = €17,153.16€/QALYs gained for palivizumab vs non-prophylaxis). One-way and probabilistic sensitivity analyses confirmed the robustness of the model. CONCLUSIONS: The prophylaxis with palivizumab is efficient for preventing from RSV infections in preterm infants 32day 1-35day 0 wGA in Spain.

RESUMEN

OBJECTIVE: To compare clinical and sonographic features of benign, borderline, and malignant invasive mucinous ovarian tumors (MOTs). MATERIALS AND METHODS: Retrospective observational multicenter study comprising 365 women (mean age: 46.1 years) with a histologically confirmed benign, borderline or malignant invasive MOT. Clinical data (patient's age, patient's complaints), tumor markers (CA-125 and CA-1 9.9), and sonographic data (tumor size, bilaterality, morphology -unilocular, multilocular, unilocular-solid, multilocular-solid and solid-, and IOTA color score) were reviewed and compared among these three groups. Women with ultrasound evidence on intra-abdominal disease spread were excluded. RESULTS: Three hundred seventy-eight MOTs (14 women had bilateral lesions) were analyzed. Histologically, 287 tumors were benign, 51 were borderline, and 40 were malignant. No difference in patient's mean age was observed. Women with borderline or invasive tumors were less frequently asymptomatic. Tumors were larger in case of invasive lesions. Borderline and invasive tumors showed solid components and exhibited IOTA color score 3 or 4, more frequently than benign lesions (p < 0.001). However, the authors discovered that 16 out of 51 (31.4%) of borderline tumors and six out of 40 (15.0%) of invasive cancers had no solid components and a color score 1 or 2, and were considered as a benign lesion by the sonolo- gist. On the other hand, 96 out of 287 (33.4%) benign mucinous cystadenoma exhibited solid components and/or a color score of 3 or 4. CONCLUSIONS: In spite of statistical differences, the authors observed significant overlapping in ultrasound features among benign, borderline, and invasive ovarian mucinous tumors that renders a difficult accurate preoperative discrimination among these lesions.

RESUMEN

Chronic venous insufficiency of the lower limbs is very prevalent. In recent decades, Doppler ultrasound has become the method of choice to study this condition, and it is considered essential when surgery is indicated. This article aims to establish a method for the examination, including venous mapping and preoperative marking. To this end, we review the venous anatomy of the lower limbs and the pathophysiology of chronic venous insufficiency and explain the basic hemodynamic concepts and the terminology required to elaborate a radiological report that will enable appropriate treatment planning and communication with other specialists. We briefly explain the CHIVA (the acronym for the French term "cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire"=conservative hemodynamic treatment for chronic venous insufficiency) strategy, a minimally invasive surgical strategy that aims to restore correct venous hemodynamics without resecting the saphenous vein.

RESUMEN

Herpes simplex virus (HSV) hepatitis is a rare and serious complication in immunocompromised patients. We report the case of an HSV hepatitis occurring 4 years after lung transplantation in a cystic fibrosis patient. The presentation was nonspecific, mimicking acute cholecystitis; orogenital signs were absent. The diagnosis was made based on viral cultures performed during cholecystectomy and confirmed by blood quantitative polymerase chain reaction. Although the diagnosis and treatment were delayed, the patient fully recovered with acyclovir, reduced immunosuppression, and intravenous immunoglobulins. The diagnostic difficulties, prognostic factors, and treatments of this infection are discussed.

RESUMEN

BACKGROUND: Infections by respiratory syncytial virus (RSV) are more severe in patients with cystic fibrosis (CF), and many CF units use palivizumab as prophylaxis; however, information about palivizumab efficacy in CF patients is almost lacking. METHODS: A literature search up to December 2012 on the morbidity of RSV bronchiolitis in CF patients and on the safety and efficacy of palivizumab in those patients was performed. A random-effects meta-analysis was conducted for those studies meeting pre-specified search criteria. Historical controls were allowed. RESULTS: The number of patients who received palivizumab was 354 and the hospital admission rate was 0.018 (95% CI 0.0077-0.048). The corresponding number in the non-treated groups was 463 patients with an admission rate of 0.126 (95% CI 0.086-0.182) (Q=13.9; p<0.001). CONCLUSION: Palivizumab may have a role in the prevention of severe lower airway infection by RSV in CF patients.

RESUMEN

INTRODUCTION: Creatine supplementation has emerged as a promising non-pharmacological therapeutic strategy to counteract muscle dysfunction and low lean mass in a variety of conditions, including in pediatric and rheumatic diseases. The objective of this study was to examine the efficacy and safety of creatine supplementation in childhood systemic lupus erythematosus (C-SLE). METHODS: C-SLE patients with mild disease activity (n = 15) received placebo or creatine supplementation in a randomized fashion using a crossover, double-blind, repeated-measures design. The participants were assessed at baseline and after 12 weeks in each arm, interspersed by an eight-week washout period. The primary outcomes were muscle function, as assessed by a battery of tests including one-maximum repetition (1-RM) tests, the timed-up-and-go test, the timed-stands test, and the handgrip test. Secondary outcomes included body composition, biochemical markers of bone remodeling, aerobic conditioning, quality of life, and physical capacity. Possible differences in dietary intake were assessed by three 24-hour dietary recalls. Muscle phosphorylcreatine content was measured through phosphorus magnetic resonance spectroscopy (31 P-MRS). The safety of the intervention was assessed by laboratory parameters, and kidney function was measured by (51)Cr-EDTA clearance. Additionally, self-reported adverse events were recorded throughout the trial. RESULTS: Intramuscular phosphorylcreatine content was not significantly different between creatine and placebo before or after the intervention (creatine-Pre: 20.5 ± 2.6, Post: 20.4 ± 4.1, placebo-Pre: 19.8 ± 2.0; Post: 20.2 ± 3.2 mmol/kg wet muscle; p = 0.70 for interaction between conditions). In addition, probably as a consequence of the lack of change in intramuscular phosphorylcreatine content, there were no significant changes between placebo and creatine for any muscle function and aerobic conditioning parameters, lean mass, fat mass, bone mass, and quality of life scores (p > 0.05). The (51)Cr-EDTA clearance was not altered by creatine supplementation and no side effects were noticed. CONCLUSION: A 12-week creatine supplementation protocol at 0.1 g/kg/d is well tolerated and free of adverse effects but did not affect intramuscular phosphorylcreatine, muscle function, free-fat mass or quality of life in non-active C-SLE patients. TRIAL REGISTRATION: Clinicaltrials.gov number: NCT01217320.

RESUMEN

Leaf epicuticular waxes provide important anatomical and chemical defences against fungi that infect leaves. In this study we analysed the leaf wax composition of Eucalyptus grandis × Eucalyptus urophylla hybrids with contrasting susceptibilities to Teratosphaeria leaf blight (TLB) caused by Teratosphaeria destructans, one of the most important foliar diseases of Eucalyptus. The Eucalyptus cuticular wax was extracted from non-inoculated and inoculated genotypes with different levels of susceptibility to TLB and analysed by gas chromatography-mass spectrometry. The results showed that a triterpenoid, cycloartenol (CAS), was abundant in a resistant genotype and that hexanedioic acid content increased in the resistant genotypes in response to T. destructans infection. In contrast, palmitic acid was significantly more abundant in the inoculated highly susceptible genotype. In-vitro and in-planta T. destructans spore germination assays with pure compounds, showed that CAS and hexanedioic acid significantly inhibited spore germination. Application of these two compounds to the leaves of a susceptible host also significantly increased resistance to infection. In contrast, palmitic acid promoted spore germination and, when applied to the leaves of a resistant genotype, increased colonization by the pathogen. This is the first study providing insights into differences in the leaf wax composition of hosts with different levels of susceptibility to T. destructans. It also showed that leaf wax compounds can modulate spore germination and, ultimately, host resistance to infection.

RESUMEN

Leishmaniasis is a zoonotic disease caused by Leishmania spp., impacts multiple systems and organs. While hematological and biochemical profiles aren't definitive for diagnosis, recent studies have identified the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) as predictors of morbidity and mortality in critically ill human and dog patients. This study examined 100 dogs diagnosed with leishmaniasis, categorized by the International Renal Interest Society (IRIS) stages 1-4. Additionally, the dogs were divided based on whether they survived less or more than one year (L1Y and G1Y). Control group consisted of 43 dogs. The NLR increased as the disease progressed (IRIS 1-4), presenting statistically significant differences (P<0.05) when compared to the control group (2,37±2,08) IRIS 3 and 4 (4,59±13,39 and 6,99±12,86, respectively), and G1Y and L1Y (3,60±4,02 and 4,87±5,82, respectively). Significant changes in SII were only evident in short-term survivors (L1Y 951,93±1402) and advanced renal disease cases (IRIS 4 stage 1073,68±1901,09). Conversely, PLR remained largely unchanged. In conclusion, these results suggest that the neutrophil-to-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) may serve as potential markers for assessing disease progression and prognosis in dogs diagnosed with leishmaniasis.

RESUMEN

OBJECTIVES: The aim of this study was to study the association of adherence to the Mediterranean diet in early pregnancy maternal and the offspring's risk of gastroschisis. METHODS: Case-control study. We describe 11 cases of gastroschisis in the region of Murcia from 2007 to 2012 and 34 concurrent controls. At the time of diagnosis each of the cases completed a validated Food Frequency Questionnaire (FFQ) consisting of 98 items on the periconceptional diet. Confounding factors: smoking, exposure to cannabis / marihuana, age of the parents, BMI, income and educational level. We conducted a descriptive and multivariate logistic regression statistical analysis. RESULTS: Mothers of children with gastroschisis were younger (20.8 years, 95% CI 17.3 to 24.2) and their diet consisted of less caloric intake, saturated fat and monounsaturated fats and proteins than controls. The Odds Ratio (OR) in the multivariate model controlling for confounding factors: maternal age (year) 0.70 (95% CI 0.51 to 0.96), monounsaturated fatty acids (oleic acid, g) 0.79 (95% CI 0.65 to 0, 97) and vegetable intake (rations/week) 0.70 (95% CI 0.48 to 1.00). CONCLUSION: A maternal diet rich in oleic acid and vegetable products may prevent vascular risk of onphalomesenteric arteries reducing the risk of gastroschisis.

RESUMEN

The identity of Syllepte Hbner, 181921 is revised by designating a neotype from Neomabra Dognin, 1905, rev. syn., for the type species S. incomptalis Hbner, 181921 because the original type material is lost, and we consider it to be congeneric with Syllepte. We redescribe Syllepte based on S. incomptalis and S. nitidalis (Dognin, 1905), rev. comb., and place Syllepte in Agroterini Acloque, 1897, and consequently synonymize Syleptinae [sic] Swinhoe, 1900, syn. rev., with Agroterini. Pantographa Lederer, 1863 and Micromartinia Amsel, 1957 are redescribed, diagnosed, and restored to their status as valid genera, rev. stat., also in the tribe Agroterini. We designate lectotypes for Neomabra nitidalis Dognin, 1905, new lectotype, rev. comb., and Pantographa scripturalis (Guene, 1854), new lectotype, rev. stat., to stabilize the names of these species. Pantographa is compared to Haritalodes Warren, 1890. We newly combine Pantographa gorgonalis Druce, 1895, n. comb., rev. stat., and Pilocrocis cyrisalis (Druce, 1895), n. comb., with Micromartinia. One hundred and ninety-six species are listed that remain misplaced in the polyphyletic Syllepte and need further revision to determine their identity and proper generic placement.

RESUMEN

In this study the aim was to resolve the taxonomy of several species of Argyria Hübner (Pyraloidea, Crambinae) with previously unrecognised morphological variation. By analysing the DNA barcode (COI-5P) in numerous specimens, the aim was to reconstruct phylogenetic relationships between species, to provide better evidence for synonymies, and to circumscribe their geographical distribution. Using an innovative DNA hybridisation capture protocol, the DNA barcode of the lectotype of Argyrialacteella (Fabricius, 1794) was partially recovered for comparison with the 229 DNA barcode sequences of Argyria specimens available in the Barcode of Life Datasystems, and this firmly establishes the identity of the species. The same protocol was used for the following type specimens: the Argyriaabronalis (Walker, 1859) holotype, thus confirming the synonymy of this name with A.lacteella, the holotype of A.lusella (Zeller, 1863), syn. rev., the holotype of A.multifacta Dyar, 1914, syn. nov. newly synonymised with A.lacteella, and a specimen of Argyriadiplomochalis Dyar, 1913, collected in 1992. In addition, nine specimens of A.lacteella, A.diplomochalis, A.centrifugens Dyar, 1914 and A.gonogramma Dyar, 1915, from North to South America were sampled using classical COI amplification and Sanger sequencing. Argyriagonogramma Dyar, described from Bermuda, is the name to be applied to the more widespread North American species formerly identified as A.lacteella. Following morphological study of its holotype, Argyriavestalis Butler, 1878, syn. nov. is also synonymised with A.lacteella. The name A.pusillalis Hübner, 1818, is considered a nomen dubium associated with A.gonogramma. The adult morphology is diagnosed and illustrated, and distributions are plotted for A.lacteella, A.diplomochalis, A.centrifugens, and A.gonogramma based on slightly more than 800 specimens. For the first time, DNA barcode sequences are provided for the Antillean A.diplomochalis. This work provides a modified, improved protocol for the efficient hybrid capture enrichment of DNA barcodes from 18th and 19th century type specimens in order to solve taxonomic issues in Lepidoptera.

RESUMEN

For the first time, genera of leaf mining Tischeriidae of the global fauna are reviewed and four new genera are described: Coptotrichoides Dikus & Stonis, gen. nov., trophically associated with Sapindaceae from Central and South America; Rytietia Dikus, Xu & Dai, gen. nov., trophically associated with Annonaceae from East and South East Asia; Pafazaria Dikus & Stonis, gen. nov., trophically associated with Fabaceae and Malvaceae from East and South East Asia; and Gnathitischeria Dikus, gen. nov., trophically associated with Malvaceae and Asteraceae from Central America. In addition to the descriptions of new genera, all previously described genera (Coptotriche Walsingham, 1890; Dishkeya Stonis, 2020; Tischeria Zeller, 1839; Manitischeria Dikus & Stonis, 2021; Neotischeria Dikus & Stonis, 2021; Paratischeria Dikus & Stonis, 2017; and Astrotischeria Puplesis & Dikus, 2003) are characterized and a pictorial identification key for all 11 genera is provided. Morphological and biological characteristics of all genera are supplemented with some molecular data. We described 12 new species: South East Asian Coptotriche sapaensis Dikus & Stonis, sp. nov.; Central American Coptotrichoides sapindoidum Dikus & Stonis, sp. nov. and Tischeria neokristenseni Dikus & Stonis, sp. nov.; South East Asian Rytietia uncinata Dikus, Xu & Dai, sp. nov., East Asian R. chongyiensis Xu & Dai, sp. nov.; South East Asian Pafazaria capitata Dikus & Stonis, sp. nov. and P. faboidica Dikus & Stonis, sp. nov.; Central American Neotischeria antigua Dikus & Remeikis, sp. nov. and N. subantigua Dikus & Remeikis, sp. nov.; South American Astrotischeria incae Dikus & Stonis, sp. nov.; and Central American Gnathitischeria atitlani Dikus & Stonis, sp. nov. and G. arcana Dikus & Stonis, sp. nov. The taxonomic rank of the East Asian subspecies Tischeria decidua siorkionla Kozlov, 1986 is elevated to species rank: T. siorkionla Kozlov (stat. nov.). The male genitalia of holotypes, paratypes, lectotypes or paralectotypes, or non-type specimens of some little-known species are examined for the first time. We provide the first morphological documentation for the following: Tischeria ceanothi lectotype and paralectotype; T. immaculata (stat. restored) paratype; Coptotrichoides deliquescens (Meyrick) lectotype and paralectotype; lectotypes of Coptotriche aenea (Frey & Boll), Astrotischeria plagifera (Meyrick), A. helianthi (Frey & Boll), and A. ephaptis (Meyrick); Coptotriche berberella (De Prins) paratype; and the first photographic documentation of Tischeria lvoskyi Kozlov holotype. Some non-type specimens deposited at NHMUK, including a few previously neglected species, are also examined and documented, including the American Astrotischeria solidagonifoliella (Clemens) and A. omissa (Braun). Nine new combinations are provided: Coptotrichoides deliquescens (Meyrick, 1915), comb. nov.; C. singularis (Stonis & Dikus) comb. nov.; C. suprafasciata (Dikus & Stonis) comb. nov., C. serjaniphaga (Remeikis & Stonis) comb. nov.; C. braziliensis (Dikus & Stonis) comb. nov.; Pafazaria jingdongensis (Xu & Dai), comb. nov.; Neotischeria explosa (Braun) comb. nov.; N. pallidipennella (Braun) comb. nov.; and Astrotischeria heteroterae (Frey & Boll) comb. nov. The synonymization of Tischeria longeciliata Frey & Boll, 1878 with Astrotischeria helianthi (Frey & Boll, 1878) is confirmed. One new species group, the Tischeria ceanothi group, is established. We also report a new distribution record of T. dodonaea Stainton from the Caucasus, Armenia. Three tables and 569 figures of adult external morphology, male and female genitalia, leaf mines, and cladograms based on molecular characters are provided.

RESUMEN

In this study, we analyse the influence of nutrition during the early neonatal period on the development and prevention of atopic dermatitis (AD) in children with a history of very low birth weight (VLBW). A retrospective cohort study was performed of VLBW preterm infants to assess the risk of their developing AD during childhood, according to nutrition with breastmilk and/or probiotic supplementation during the neonatal period. The analysis focused on nutritional and early childhood follow-up data for 437 newborns, of whom 184 received probiotics up to 36 weeks postmenstrual age. AD was present in 23.5% of the study sample. Of the children who did not develop AD, 44.9% had received probiotics from birth to 36 weeks of gestational age. Therefore, the administration of probiotics to infants at less than 36 weeks postmenstrual age is associated with a protective effect against the development of AD (odds ratio (OR) 0.57; 95% confidence interval (CI) 0.34-0.93). Moreover, a protective interaction was observed between probiotic administration and breastmilk (OR 0.46; 95% CI 0.25-0.82). The adjusted data in the regression model allow us to observe a statistically significant association with the protective effect of Lacticaseibacillus rhamnosus with the development of AD at school age (OR 0.55; 95% CI 0.30-0.99). Probiotic supplementation in VLBW newborns is associated with a decreased risk of subsequent development of AD. Breastmilk strengthens the protective effect of probiotics against the development of AD.

RESUMEN

The use of DNA barcoding has revolutionised biodiversity science, but its application depends on the existence of comprehensive and reliable reference libraries. For many poorly known taxa, such reference sequences are missing even at higher-level taxonomic scales. We harvested the collections of the Smithsonian's National Museum of Natural History (USNM) to generate DNA barcoding sequences for genera of terrestrial arthropods previously not recorded in one or more major public sequence databases. Our workflow used a mix of Sanger and Next-Generation Sequencing (NGS) approaches to maximise sequence recovery while ensuring affordable cost. In total, COI sequences were obtained for 5,686 specimens belonging to 3,737 determined species in 3,886 genera and 205 families distributed in 137 countries. Success rates varied widely according to collection data and focal taxon. NGS helped recover sequences of specimens that failed a previous run of Sanger sequencing. Success rates and the optimal balance between Sanger and NGS are the most important drivers to maximise output and minimise cost in future projects. The corresponding sequence and taxonomic data can be accessed through the Barcode of Life Data System, GenBank, the Global Biodiversity Information Facility, the Global Genome Biodiversity Network Data Portal and the NMNH data portal.
