Adequacy of antenatal care and its relationship with low birth weight in Botucatu, São Paulo, Brazil: a case-control study

Background: Birth weight reflects gestational conditions and development during the fetal period. Low birth weight (LBW) may be associated with antenatal care (ANC) adequacy and quality. the purpose of this study was to analyze ANC adequacy and its relationship with LBW in the Unified Health System in Brazil.Methods: A case-control study was conducted in Botucatu, São Paulo, Brazil, 2004 to 2008. Data were collected from secondary sources (the Live Birth Certificate), and primary sources (the official medical records of pregnant women). the study population consisted of two groups, each with 860 newborns. the case group comprised newborns weighing less than 2,500 grams, while the control group comprised live newborns weighing greater than or equal to 2,500 grams. Adequacy of ANC was evaluated according to three measurements: 1. Adequacy of the number of ANC visits adjusted to gestational age; 2. Modified Kessner Index; and 3. Adequacy of ANC laboratory studies and exams summary measure according to parameters defined by the Ministry of Health in the Program for Prenatal and Birth Care Humanization.Results: Analyses revealed that LBW was associated with the number of ANC visits adjusted to gestational age (OR = 1.78, 95% CI 1.32-2.34) and the ANC laboratory studies and exams summary measure (OR = 4.13, 95% CI 1.36-12.51). According to the modified Kessner Index, 64.4% of antenatal visits in the LBW group were adequate, with no differences between groups.Conclusions: Our data corroborate the association between inadequate number of ANC visits, laboratory studies and exams, and increased risk of LBW newborns. No association was found between the modified Kessner Index as a measure of adequacy of ANC and LBW. This finding reveals the low indices of coverage for basic actions already well regulated in the Health System in Brazil. Despite the association found in the study, we cannot conclude that LBW would be prevented only by an adequate ANC, as LBW is associated with factors of complex and multifactorial etiology. the results could be used to plan monitoring measures and evaluate programs of health care assistance during pregnancy, at delivery and to newborns, focusing on reduced LBW rates.Dean's Office for Research Projects, (PROPE)UNESP - Paulista State UniversityUNESP, Paulista State Univ, Botucatu Med Sch, Dept Pediat, Botucatu, SP, BrazilUniversidade Federal de São Paulo, UNIFESP, Dept Pediat, São Paulo, BrazilUNESP, Paulista State Univ, Inst Biosci, Dept Biostat, Botucatu, SP, BrazilUniversidade Federal de São Paulo, UNIFESP, Dept Pediat, São Paulo, BrazilWeb of Scienc

Whole-genome sequencing enables molecular characterization of non-clonal group 258 high-risk clones (ST13, ST17, ST147 and ST307) among Carbapenem-resistant Klebsiella pneumoniae from a tertiary university hospital centre in Portugal

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).The carbapenem-resistant Enterobacterales (CRE) strains have been identified by the World Health Organization as critical priority pathogens in research and development of diagnostics, treatments, and vaccines. However, recent molecular information about carbapenem-resistant K. pneumoniae (CRK) epidemiology in Portugal is still scarce. Thus, this study aimed to provide the molecular epidemiology, resistome, and virulome of CRK clinical strains recovered from a tertiary care hospital centre (2019–2021) using polymerase chain reaction (PCR) and the advanced molecular technique whole-genome sequencing (WGS). PCR amplification of carbapenemase genes was performed in 437 carbapenem-resistant K. pneumoniae strains. The most frequent carbapenemases were: KPC-3 (42%), followed by OXA-181 (20%), GES-5 (0.2%), and NDM-1 (0.2%). Additionally, 10 strains (2%) coproduced KPC-3 and OXA-181, and 1 strain coproduced KPC-3 and OXA-48 (0.2%). The genomic population structure of 68 strains characterized by WGS demonstrated the ongoing dissemination of four main high-risk clones: ST13, ST17, ST147, and ST307, while no clones belonging to the European predominant clonal groups (CG15 and CG258) were found. Moreover, we describe one K. pneumoniae ST39-KL62 that coproduced the NDM-1 carbapenemase and the extended-spectrum beta-lactamase CTX-M-15, and one K. pneumoniae ST29-KL54 GES-5 and BEL-1 coproducer. Furthermore, a high prevalence of iron siderophores were present in all CRK strains, with several strains presenting both colibactin and the hypermucoviscosity phenotype. Thus, the data presented here highlight an uncommon molecular epidemiology pattern in Portugal when compared with most European countries, further supporting the emergence and dissemination of nonclonal group 258 hypervirulent multidrug high-risk clones and the need to promote in-depth hospital molecular surveillance studies.This research was partially funded by Fundação para a Ciência e a Tecnologia (FCT), under grant numbers UIDB/04295/2020 and UIDP/04295/2020.

First description of Ceftazidime/Avibactam resistance in an ST13 KPC-70-producing Klebsiella pneumoniae strain from Portugal

© 2022 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).The combination of ceftazidime/avibactam (CZA) is a novel β-lactam/β-lactamase inhibitor with activity against Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacterales. Emerging cases caused by CZA-resistant strains that produce variants of KPC genes have already been reported worldwide. However, to the best of our knowledge, no CZA-resistant strains were reported in Portugal. In September 2019, a K. pneumoniae CZA-resistant strain was collected from ascitic fluid at a surgery ward of a tertiary University Hospital Center in Lisboa, Portugal. The strain was resistant to ceftazidime/avibactam, as well as to ceftazidime, cefoxitin, gentamicin, amoxicillin/clavulanic acid, and ertapenem, being susceptible to imipenem and tigecycline. A hypermucoviscosity phenotype was confirmed by string test. Whole-genome sequencing (WGS) analysis revealed the presence of an ST13 KPC70-producing K. pneumoniae, a KPC-3 variant, differing in two amino-acid substitutions (D179Y and T263A). The D179Y mutation in the KPC Ω-loop region is the most common amino-acid substitution in KPC-2 and KPC-3, further leading to CZA resistance. The second mutation causes a KPC-70 variant in which threonine replaces alanine (T263A). The CZA-resistant strain showed the capsular locus KL3 and antigen locus O1v2. Other important virulence factors were identified: fimbrial adhesins type 1 and type 3, as well as the cluster of iron uptake systems aerobactin, enterobactin, salmochelin, and yersiniabactin included in integrative conjugative element 10 (ICEKp10) with the genotoxin colibactin cluster. Herein, we report the molecular characterization of the first hypervirulent CZA-resistant ST13 KPC-70-producing K. pneumoniae strain in Portugal. The emergence of CZA-resistant strains might pose a serious threat to public health and suggests an urgent need for enhanced clinical awareness and epidemiologic surveillance.This research was partially funded by the Fundação para a Ciência e a Tecnologia (FCT), grant number UIDB/04295/2020 and UIDP/04295/2020.

Patient experience in home respiratory therapies : where we are and where to go

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/).The increasing number of patients receiving home respiratory therapy (HRT) is imposing a major impact on routine clinical care and healthcare system sustainability. The current challenge is to continue to guarantee access to HRT while maintaining the quality of care. The patient experience is a cornerstone of high-quality healthcare and an emergent area of clinical research. This review approaches the assessment of the patient experience in the context of HRT while highlighting the European contribution to this body of knowledge. This review demonstrates that research in this area is still limited, with no example of a prescription model that incorporates the patient experience as an outcome and no specific patient-reported experience measures (PREMs) available. This work also shows that Europe is leading the research on HRT provision. The development of a specific PREM and the integration of PREMs into the assessment of prescription models should be clinical research priorities in the next several years.C.J. has a post-doctoral grant (SFRH/BPD/115169/2016) funded by Fundação para a Ciência e a Tecnologia (FCT), co-financed by the European Social Fund (POCH) and Portuguese national funds from MCTES (Ministério da Ciência, Tecnologia e Ensino Superior).info:eu-repo/semantics/publishedVersio

Enhance access to pulmonary rehabilitation with a structured and personalized home-based program—reabilitAR: protocol for real-world setting

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).Home-based models represent one of the solutions to respond to the poor accessibility of pulmonary rehabilitation (PR) services in patients with chronic respiratory disease (CRD). The main goal of this protocol is to present the implementation of the first nationwide home-based PR program—reabilitAR—in Portugal and the strategies to assess its benefits in patients with CRD. The program consists of 2 phases: a 12-week intensive phase and a 40-week maintenance phase (total: 52 weeks, 1 year). The intervention in both phases is composed of presential home visits and phone-call follow ups, including exercise training and the self-management educational program Living Well with COPD. Dyspnea, impact of the disease, emotional status, and level of dyspnea during activities of daily living are used as patient-reported outcomes measures. A one-minute sit-to-stand test is used as a functional outcome, and the number of steps as a measure of physical activity. To ensure safety, fall risk and the cognitive function are assessed. Data are collected at baseline, at 12 weeks, at 26 weeks and at 52 weeks. This is the first nationwide protocol on enhancing access to PR, providing appropriate responses to CRD patients’ needs through a structured and personalized home-based program in Portugal.info:eu-repo/semantics/publishedVersio

A qualitative study of patient and carer experiences with home respiratory therapies: long-term oxygen therapy and home mechanical ventilation

© 2021 Sociedade Portuguesa de Pneumologia. Published by Elsevier España, S.L.U. This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/)Studies exploring the experience of patients receiving home respiratory therapies (HRT), such as long-term oxygen therapy (LTOT) and home mechanical ventilation (HMV), are still limited. This study focused on patients' and carers' experience with LTOT and HMV. An exploratory, cross-sectional qualitative study, using semi-structured focus groups, was carried out with 18 patients receiving HRT (median 71y, 78% male, 56% on both LTOT and HMV) and 6 carers (median age 67y, 67% female). Three focus groups were conducted in three regions of Portugal. Thematic analysis was performed by two independent researchers. Patients' and carers' experience was reflected in seven major topics, linked to specific time points and settings of the treatment: Initial symptoms/circumstances (n = 41), Prescription (n = 232), Implementation (n = 184), Carer involvement (n = 34), Quality of life impact (n = 301), Health care support/navigability (n = 173) and Suggestions (n = 14). Our findings demonstrate a general good perception of the HRT by patients and carers recognizing a significative quality of life impact improvement, while identifying specific points where improvements in healthcare are needed, particularly about navigability issues, articulation between the hospital, primary care and homecare teams, especially regardingprescriptionrenewal. This knowledge is crucial to promote a long-term HRT adherence and to optimize HRT delivery in line with patients' experience, needs, and values. Moreover, these key points can inform the development of a specific patient-reported experience measure (PREM) for patients on HRT, which is not currently available, and foster a more integrated respiratory care model.info:eu-repo/semantics/publishedVersio

The Portuguese model of home respiratory care: healthcare professionals’ perspective

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).Patients' and carers' views regarding the Portuguese model of home respiratory care were recently described, yet the complementary perspective of healthcare professionals (HCPs) is still to be investigated. Thus, this study explored HCPs experience in the management of patients needing home respiratory therapies (HRT), and their perspective about the Portuguese model. A phenomenological descriptive study, using focus groups, was carried out with 28 HCPs (median 42 y, 68% female) with distinct backgrounds (57% pulmonologists, 29% clinical physiologists, 7% physiotherapists, 7% nurses). Three focus groups were conducted in three regions of Portugal. Thematic analysis was performed by two independent researchers. HCPs have in general a positive view about the organization of the Portuguese model of home respiratory care, which was revealed in four major topics: Prescription (number of references, n = 171), Implementation and maintenance (n = 162), Carer involvement (n = 65) and Quality of healthcare (n = 247). Improvements needed were related to patients' late referral, HRT prescription (usability of the medical electronic prescription system and renewals burden), patients' education, access to hospital care team, lack of multidisciplinary work and articulation between hospital, primary and home care teams. This study describes the perspective of HCPs about the Portuguese model of home respiratory care and identifies specific points where improvements and reflections are needed. This knowledge may be useful to decision makers improve the current healthcare model.info:eu-repo/semantics/publishedVersio

Guidelines for the Detection of Babesia and Theileria Parasites.

The genera Babesia and Theileria (phylum Apicomplexa, order Piroplasmida) are mainly transmitted by Ixodid ticks in which the sexual part of their life cycle followed by sporogony takes place. They include protozoan parasites that infect erythrocytes of a variety of vertebrate hosts, including domestic and wild animals, with some Babesia spp. also infecting humans. Babesia sporozoites transmitted in the tick's saliva during the bloodmeal directly infect erythrocytes, where they asexually multiply to produce pear-shaped merozoites in the process of merogony; whereas a pre-erythrocytic schizogonic life stage in leukocytes is found in Theileria and precedes merogony in the erythrocytes. The wide spectrum of Babesia and Theileria species and their dissimilar characteristics with relation to disease severity, transmission, epidemiology, and drug susceptibility stress the importance of accurate detection of babesiosis and theileriosis and their causative agents. These guidelines review the main methods currently used for the detection of Babesia and Theileria spp. for diagnostic purposes as well as epidemiological studies involving their vertebrate hosts and arthropod vectors. Serological methods were not included once they did not indicate current infection but rather exposure.Peer reviewe
