En conclusión, los talleres lúdicos ayudan a mejorar el aprendizaje de los estudiantes y al mismo tiempo promover habilidades positivas como el respeto, solidaridad, y empatía por sus paresThe main objective of this research entitled Playful workshop for socio- emotional development in 4-year-old children from a private institution in Trujillo, 2023 was to determine how the playful workshop influences socio-emotional development in 4-year-old children from a private institution in Trujillo 2023, so we propose to provide significant experiences in the development of playful activities that facilitate the child's socio-emotional development, being an applied research with a pre-experimental design. The census population consists of 23 4-year-old children. Likewise, an assessment scale was used as an instrument, this instrument has a total of 20 items and was validated through expert judgment, achieving a high level of reliability of .896 through Cronbach's Alpha. Subsequently, the pre-test and post-test were applied after applying the direct experiences as a strategy and the results were validated through the ""Student's t"". When performing the t-test, to make the comparison of samples of the scientific thinking variable, the scores obtained from the posttest and pretest, a significance less than 0.05 (Sig=0.000) was obtained, therefore, we can affirm that there are statistically significant differences. The results conclude that 5 year-olds have a high level in socio-emotional development with a score of 82.6%, the good level with 13.0% and in the regular level 4.3% and in the deficient level with 0.0. In conclusion, playful workshops help to improve students' learning and at the same time promote positive skills such as respect, solidarity, and empathy for their peersTesi

Pediatric visceral leishmaniasis in Western Sicily, Italy: a retrospective analysis of 111 cases

The clinical and epidemiological characteristics of 111 consecutive cases of visceral leishmaniasis identified from 1980 to 2000 in a Sicilian pediatric hospital were analyzed retrospectively. The mean age of the patients was 1.7 years. All children were HIV negative, but 15% were severely malnourished. Fever and splenomegaly were present in all cases and hepatomegaly in 101 (90.1%) cases. Thrombocytopenia and anemia were both observed in 78 (70.2%) cases and leukopenia in 47 (42.3%) cases. A bone marrow aspirate was obtained in all cases; Leishmania amastigotes were detected in 89 (80.2%) cases. Initial treatment consisted of meglumine antimoniate in 99 (89.2%) patients and amphotericin B in 12 (10.8%) patients. Only two children treated with meglumine antimoniate relapsed. The findings highlight the differences between the cases of visceral leishmaniasis observed in the Mediterranean basin and those observed in other regions. The use of the term "Mediterranean visceral leishmaniasis", rather than the term "kala-azar", is proposed for cases observed in the Mediterranean are

Treatment of human brucellosis with rifampin plus minocycline

In order to evaluate the efficacy and tolerability of a high intravenous dose of rifampin plus oral minocycline (administered daily for 3 weeks) for the treatment of acute brucellosis, we retrospectively reviewed the outcome of 239 consecutive patients (135 adults and 104 children) diagnosed and treated over a 17-year period in Italy. The combination used resulted in 100% response and a relapse rate lower than 2%. Fifty-two (30 adults and 22 children) (29.8%) complained of mild adverse effects including an increase in aspartate aminotransferase (>250 IU) observed in 12 cases and considered related to rifampin and in 11 cases a reversible hyperpigmentation of the tongue attributed to minocycline. A randomized prospective comparative study should be performed to confirm our encouraging result

Spatial Concentration Profiles for the Catalytic Partial Oxidation of Jet Fuel Surrogates in a Rh/Al₂O₃ Coated Monolith

The catalytic partial oxidation (CPOX) of several hydrocarbon mixtures, containing n-dodecane (DD), 1,2,4-trimethylbenzene (TMB), and benzothiophene (BT) as a sulfur compound was studied over a Rh/Al2O3 honeycomb catalyst. The in-situ sampling technique SpaciPro was used in this study to investigate the complex reaction system which consisted of total and partial oxidation, steam reforming, and the water gas shift reaction. The mixtures of 83 vol % DD, 17 vol % TMB with and without addition of the sulfur compound BT, as well as the pure hydrocarbons were studied at a molar C/O-ratio of 0.75. The spatially resolved concentration and temperature profiles inside a central channel of the catalyst revealed three reaction zones: an oxidation zone, an oxy-reforming zone, and a reforming zone. Hydrogen formation starts in the oxy-reforming zone, not directly at the catalyst inlet, contrary to methane CPOX on Rh. In the reforming zone, in which steam reforming is the predominant reaction, even small amounts of sulfur (10 mg S in 1 kg fuel) block active sites

Recent transmission clustering of HIV-1 C and CRF17_BF strains characterized by NNRTI-related mutations among newly diagnosed men in central Italy

Increased evidence of relevant HIV-1 epidemic transmission in European countries is being reported, with an increased circulation of non-B-subtypes. Here, we present two recent HIV-1 non-B transmission clusters characterized by NNRTI-related amino-acidic mutations among newly diagnosed HIV-1 infected men, living in Rome (Central-Italy)

Polymerase chain reaction in the diagnosis and prognosis of Mediterranean visceral leishmaniasis in immunocompetent children

OBJECTIVE: To assess the usefulness of a polymerase chain reaction (PCR) assay amplifying the small subunit rRNA coding region of Leishmania species performed on peripheral blood (PB) and bone marrow (BM) aspirates for the diagnosis and follow-up of visceral leishmaniasis (VL) in children living in the Mediterranean basin. DESIGN: A prospective study was conducted on children consecutively hospitalized over a 1-year period at our Infectious Diseases Department in Sicily (Italy) presenting with fever, hepatosplenomegaly, and/or pancytopenia and a positive Leishmania serology (> or =1:40). RESULTS: Among the 14 patients hospitalized with signs and symptoms suggestive of the disease and a positive serology, we identified 10 cases of Mediterranean VL. PCR performed on PB and BM aspirates was positive in all cases and concordant with microscopy and/or culture performed on BM. Leishmania DNA was cleared from PB a median of 6 days after the start of treatment; during follow-up (median: 9 months; range: 6-12 months) 1 child relapsed. In this case, BM PCR remained positive with rapid reappearance of a positive signal also in PB. CONCLUSIONS: PB PCR allows a rapid and noninvasive parasitologic diagnosis of Mediterranean VL among immunocompetent children and is at least as sensitive as a diagnosis made on the basis of BM aspirates. The lack of disappearance from BM and the reappearance of positive PCR on PB is predictive of clinical relapse. Qualitative and semiquantitative PCR may be the standard method for monitoring response to therapy in immunocompetent childre

Clinical use of polymerase chain reaction performed on peripheral blood and bone marrow samples for the diagnosis and monitoring of visceral leishmaniasis in HIV-infected and HIV-uninfected patients: a single-center, 8-year experience in Italy and review of the literature

Background. To overcome some of the limitations of conventional microbiologic techniques, polymerase chain reaction (PCR)–based assays are proposed as useful tools for the diagnosis of visceral leishmaniasis. Patients and methods. A comparative study using conventional microbiologic techniques (i.e., serologic testing, microscopic examination, and culture) and a Leishmania species–specific PCR assay, using peripheral blood and bone marrow aspirate samples as templates, was conducted during an 8-year period. The study cohort consisted of 594 Italian immunocompetent (adult and pediatric) and immunocompromised (adult) patients experiencing febrile syndromes associated with hematologic alterations and/or hepatosplenomegaly. Identification of the infecting protozoa at the species level was directly obtained by PCR of peripheral blood samples, followed by restriction fragment–length polymorphism analysis of the amplified products, and the results were compared with those of isoenzyme typing of Leishmania species strains from patients, which were isolated in vitro. Results. Sixty-eight patients (11.4%) had a confirmed diagnosis of visceral leishmaniasis. Eleven cases were observed in human immunodeficiency virus (HIV)–uninfected adults, 20 cases were observed in HIV-infected adults, and the remaining 37 cases were diagnosed in HIV-uninfected children. In the diagnosis of primary visceral leishmaniasis, the sensitivities of the Leishmania species–specific PCR were 95.7% for bone marrow aspirate samples and 98.5% for peripheral blood samples versus sensitivities of 76.2%, 85.5%, and 90.2% for bone marrow aspirate isolation, serologic testing, and microscopic examination of bone marrow biopsy specimens, respectively. None of 229 healthy blood donors or 25 patients with imported malaria who were used as negative control subjects had PCR results positive for Leishmania species in peripheral blood samples (i.e., specificity of Leishmania species– specific PCR, 100%). PCR and restriction fragment–length polymorphism analysis for Leishmania species identification revealed 100% concordance with isoenzyme typing in the 19 patients for whom the latter data were available. Conclusions. PCR assay is a highly sensitive and specific tool for the diagnosis of visceral leishmaniasis in both immunocompetent and immunocompromised patients and can be reliably used for rapid parasite identification at the species level

A 6 day course of liposomal amphotericin B in the treatment of infantile visceral leishmaniasis: the Italian experience

OBJECTIVES: To evaluate in a retrospective analysis the efficacy and safety of a 6 day course of liposomal amphotericin B (L-AmB) in infantile cases of Mediterranean visceral leishmaniasis (VL) diagnosed over a 10 year period in Italy. PATIENTS AND METHODS: Patients included were diagnosed as having VL consecutively admitted from December 1992 to December 2001 at four main referral children's hospitals in Italy and treated with six intravenous doses of 3 mg/kg L-AmB given on days 1-5 and 10 (a total dose of 18 mg/kg). Demographic data, nutritional status, underlying diseases, clinical and laboratory findings, and therapy outcome were considered. RESULTS: A total of 164 HIV-negative children (median age 1.6 years; range 4 months to 14 years) were enrolled. All patients were initially cured by the given treatment, and did not present adverse events related to drug infusion. Seven patients (4.3%) had a clinical and parasitological relapse 3-15 months after therapy. All relapses were successfully retreated with 3 mg/kg L-AmB for 10 consecutive days (a total dose of 30 mg/kg). CONCLUSIONS: This study highlights the efficacy (>95%) and safety of the six dose L-AmB regimen and validates it as a first-line treatment for Mediterranean VL in children

Evaluation of HIV-1 integrase resistance emergence and evolution in patients treated with integrase inhibitors.

Abstract Objectives We evaluated the emergence of mutations associated to integrase strand transfer inhibitors (INSTI) resistance (INSTI-RMs) and the integrase evolution in HIV-1 infected patients treated with this drug class. Methods Emergence of INSTI-RMs and integrase evolution (estimated as genetic distance between integrase sequences under-INSTI and before-INSTI treatment) were evaluated in 107 INSTI-naive patients (19 drug-naive and 88 drug-experienced) with two plasma genotypic resistance tests available: one before and one under INSTI treatment. A logistic regression analysis was performed to evaluate factors associated with the integrase evolution under INSTI treatment. Results Patients were mainly infected by B subtype (72.0%). 87 patients were treated with raltegravir, 13 with dolutegravir and 7 with elvitegravir. Before INSTI treatment, one patient harboured the major INSTI-RM R263 K, and three patients the accessory INSTI-RMs T97A. Under INSTI treatment, the emergence of ≥1 INSTI-RM was found in 39 (36.4%) patients. The major INSTI-RMs which emerged more frequently were: N155H (17.8%), G140S (8.4%), Y143R (7.5%), Q148H (6.5%), Y143C (4.7%). Concerning integrase evolution, a higher genetic distance was found in patients with ≥1 INSTI-RM compared to those without emergence of resistance (0.024 [0.012-0.036] vs. 0.015 [0.009-0.024], p = 0.018). This higher integrase evolution was significantly associated with a longer duration of HIV-1 infection, a higher number of past regimens and non-B subtypes. Conclusions Our findings confirmed that in INSTI-naive patients, major INSTI-RMs occur very rarely. Under INSTI treatment, selection of drug-resistance follows the typical drug-resistance pathways; a higher evolution characterizes integrase sequences developing drug-resistance compared to those without any resistance
