Intersectionality and challenges in support for chest-feeding transgender men. / Desafios para o suporte à amamentação em homens transgêneros sob à luz da interseccionalidade.

This article tried, from an intersectional standpoint, to grasp the challenges experienced by health professionals and service users of human milk banks in provision of care for transgender men chestfeeding. This exploratory, descriptive qualitative study drew on interviews of six human milk bank staff, who had previously assisted trans men in relation to chestfeeding and two bisexual trans men, who chestfed. The data was treated by thematic analysis, supported by Atlas.ti software, version 9.0. Lacunas in the educational, institutional and management spheres, associated with personal and social issues, reproduce a pre-conceived normative model and disregard the special demands of providing chestfeeding care for the trans population. Cisheteronormativity and "professional supremacy" operate in personal, social and institutional respects to segregate transgender men in lactation support services. Intersectional analysis of these challenges affords an overall view of segregative factors and enables public policies to be introduced to promote social justice.

Toothpaste containing TiF4 and chitosan against erosive tooth wear in situ.

OBJECTIVE: This study compared the protective effect of an experimental TiF4/Chitosan toothpaste with a commercial toothpaste on the prevention of erosive tooth wear (ETW) in situ. METHODS: Fifteen subjects took part in this crossover and double-blind study, in which they wore a palatal appliance containing 4 bovine enamel and 4 dentin in 3 phases (5 days each). Half of the samples were subjected to erosive challenges (90 s in 0.1 % citric acid, pH 2.5, 4 times/day), and the other half to erosive plus abrasive challenges (15 s plus 45 s of contact, 2 times/day). The phases corresponded to the application of the different toothpastes: 1) TiF4 (1400 ppm F-) plus Chitosan, 2) Elmex®, Erosion Protection (1400 ppm F-, Chitosan), and 3) Placebo (negative control). Tooth wear was measured using contact profilometry (µm) and submitted to two-way RM ANOVA/Tukey test (p < 0.05). RESULTS: No significant differences were detected between the experimental and commercial toothpastes, regardless of the challenge on both tissues. Both significantly reduce ETW compared to negative control (p < 0.0006). Tooth wear was increased by brushing only on eroded enamel (p < 0.01), but not on dentin (p = 0.6085). TiF4/Chitosan [erosion 2.98 ± 1.12 µm vs. erosion and abrasion 3.12 ± 1.33 µm] and Elmex® toothpastes [erosion 2.35 ± 0.93 µm vs. erosion and abrasion 2.98 ± 1.0 µm] minimized the impact of brushing compared to placebo on enamel [erosion 4.62 ± 1.48 µm vs. erosion and abrasion 5.15 ± 1.50 µm]. CONCLUSIONS: TiF4 plus chitosan toothpastes showed to be effective in minimizing the ETW as the commercial toothpaste is in situ. CLINICAL RELEVANCE: The experimental toothpaste has similar effect against ETW compared to the commercial toothpaste. Considering the increased ETW prevalence worldwide, this result supports clinical trials and a possible application of this experimental anti-erosive toothpaste in the future.

Antimicrobial and antibiofilm activity of highly soluble polypyrrole against methicillin-resistant Staphylococcus aureus.

AIMS: The purpose was to evaluate the antimicrobial activity of highly soluble polypyrrole (Hs-PPy), alone or combined with oxacillin, as well as its antibiofilm potential against methicillin-resistant Staphylococcus aureus strains. Furthermore, the in silico inhibitory mechanism in efflux pumps was also investigated. METHODS AND RESULTS: Ten clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA) and two reference strains were used. Antimicrobial activity was determined by broth microdilution, and the combination effect with oxacillin was evaluated by the checkerboard assay. The biofilm formation capacity of MRSA and the interference of Hs-PPy were evaluated. The inhibitory action of Hs-PPy on the efflux pump was evaluated in silico through molecular docking. Hs-PPy showed activity against the isolates, with inhibitory action between 62.5 and 125 µg ml-1 and bactericidal action at 62.5 µg ml-1, as well as synergism in association with oxacillin. The isolates ranged from moderate to strong biofilm producers, and Hs-PPy interfered with the formation of this structure, but not with mature biofilm. There was no in silico interaction with the efflux protein EmrD, the closest homolog to NorA. CONCLUSIONS: Hs-PPy interferes with biofilm formation by MRSA, has synergistic potential, and is an efflux pump inhibitor.

Optimizing the management of thyroid specimens to efficiently generate whole slide images for diagnosis.

Transition from optical to digital observation requires an additional procedure in the pathology laboratory, the scanning of glass slides, leading to increased time and digital archive consumption. Thyroid surgical samples often carry the need to collect several tissue fragments that generate many slides to be scanned. This study evaluated the impact of using different inking colours for the surgical margin, section thickness, and glass slide type, in the consumption of time and archive. The series comprehended 40 nodules from 30 patients, including 34 benign nodules in follicular nodular disease, 1 NIFTP, and 5 papillary carcinomas. In 12 nodules, the dominant pattern was microfollicular/solid and in 28 it was macrofollicular. Scanning times/mm2 were longer in red-inked fragments in comparison to green (p = 0.04) and black ones (p = 0.024), and in blue-inked in comparison to green ones (p = 0.043). File sizes/mm2 were larger in red-inked fragments in comparison to green (p = 0.008) and black ones (p = 0.002). The dominant pattern microfollicular/solid was associated with bigger file size/mm2 in comparison with the macrofollicular one (p < 0.001). All scanner outputs increase significantly with the thickness of the section. All scanning outputs increase with the usage of adhesive glass slides in comparison to non-adhesive ones. Small interventions in thyroid sample management that can help optimizing the digital workflow include to prefer black and green inking colours for the surgical margins and 2 µm section in non-adhesive glass slides for increased efficiency.

Synergism between molecules derived from Garcinia brasiliensis and antimicrobial drugs on field isolates of Mycoplasma hyopneumoniae.

Mycoplasma hyopneumoniae (M. hyopneumoniae) is one of the smallest free-living bacteria found in nature; it has an extremely small genome and lacks a cell wall. It is the main etiological agent of porcine enzootic pneumonia (EP), a chronic respiratory disease with worldwide distribution that causes significant losses in swine production. Due to the great economic impact caused by EP, new strategies for treating and controlling this agent are researched. The objective of this study was to verify the anti-M. hyopneumoniae activity of compounds derived from Garcinia brasiliensis and the synergism with the main antimicrobials used in the treatment of EP; this is the first study assessing the synergism between bioactive molecules and antimicrobial compounds in vitro against isolates of M. hyopneumoniae. The minimum inhibitory concentrations (MICs) of the antimicrobials tiamulin, valnemulin, and enrofloxacin, as well as the bioactive compounds guttiferone-A (Gut-A), 7-epiculsone (7-Epic), copper 7-epiculsone (7-Epic-Cu), and benzophenone, were determined. Subsequently, the interactions of antibiotics with the compounds were evaluated using the checkerboard method. Three field M. hyopneumoniae isolates were used, and the J strain was used as a control. The MIC values of the antimicrobials compared to the field isolates were equal to and lower than those of the reference strain J. Among the compounds used, 7-Epic-Cu showed the lowest MIC value. Synergistic association was observed for Gut-A with tiamulin and valnemulin, whereas 7-Epic and 7-Epic-Cu showed synergistic action with enrofloxacin. No synergistic effect was observed for benzophenone. Despite being an initial study, the results suggest that these combinations hold promise for the treatment of infections caused by M. hyopneumoniae.

METHOD: Interpretative analysis, based on the assumptions of the Grounded Theory and Symbolic Interactionism. For data collection, Culture Circles were conducted with 18 adolescents from October 2020 to August 2021. RESULTS: The theoretical archetype is structured based on the recognition of vulnerable youth context, and the development of potential through collective relations built by dialogue, trust, shared knowledge construction, and the use of technologies. FINAL CONSIDERATIONS: The theoretical structure on literacy practices committed to empowerment through the understanding of adolescents runs through the framework of a substantive theory that culminates in a perspective of agency and recognition of their needs.

Effective Postoperative Pain Management in Thoracic Outlet Syndrome Surgery: The Role of the Erector Spinae Plane Block.

Thoracic outlet syndrome (TOS) often necessitates surgical intervention to alleviate neurovascular bundle compression, which can result in severe postoperative pain. The myriad of surgical techniques available for TOS treatment, the intricate involvement of diverse sensory pathways, and the limited literature on effective analgesic methods for these specific cases underscore the need for successful approaches. This report introduces an efficacious multimodal analgesic strategy that incorporates the erector spinae plane (ESP) block to enhance postoperative pain management after a supraclavicular surgical approach. By combining this fascial block with a comprehensive rationale for its implementation, this case offers valuable insights into improving the postoperative care of TOS patients, ultimately aiming to enhance their comfort and recovery.

Multidrug Efflux System-mediated resistance in Staphylococcus aureus under a One Health approach.

The aim of the study was to track the spread of antimicrobial resistance among the different sectors of One Health through the detection of Multidrug-Efflux-System in multidrug-resistant Staphylococcus aureus isolates. Multidrug-resistant (MDR) and methicillin-resistant (MRSA) S. aureus isolates were selected: 25 of human, one of animal and eight of food origin. The efflux system genes norA, norB, norC, LmrS, tet38 and msrA were screened by PCR. The activity of the efflux systems was determined by the minimum inhibitory concentration (MIC) of tetracycline and ciprofloxacin in the presence and absence of CCCP and in the quantification of ethidium bromide efflux. Furthermore, biofilm formation was determined in the presence and absence of the CCCP. The molecular epidemiology of the isolates was traced with the aid of PFGE. The gene norC was the most prevalent, detected in all isolates and msrA was the least prevalent, detected in only two isolates from humans. There was no difference in the MICs of tetracycline and ciprofloxacin in the presence of CCCP, but 55.9% of isolates showed ethidium bromide efflux. The presence of CCCP decreased the biofilm formation. Regarding the molecular epidemiology, in three clusters was a mixture of the isolates from different origins. Therefore, S. aureus MDR with active multidrug efflux systems are circulating between One Health domains and it is necessary to consider strategies to decrease this circulation in order to prevent the dissemination of resistance mediated by MES.

Demonstrating the interference of tissue processing in the evaluation of tissue biomarkers: The case of PD-L1.

The immunohistochemical (IHC) expression of PD-L1 in cancer models is used as a predictive biomarker of response to immunotherapy. We aimed to evaluate the impact of the usage of 3 different tissue processors in the IHC expression of PD-L1 antibody clones: 22C3 and SP142. Three different topographies of samples (n = 73) were selected at the macroscopy room: 39 uterine leiomyomas, 17 placentas and 17 palatine tonsils. Three fragments were collected from each sample and were inked with a specific color that represented their separate processing in a different tissue processor (A, B or C). During embedding, the 3 fragments with distinct processing were ensemble in the same cassette for sectioning of 3 slides/each: hematoxylin-eosin, 22C3 PDL1 IHC staining and SP142 PD-L1 IHC staining, that were blindly observed by 2 pathologists under digital environment. All but one set of 3 fragments were considered adequate for observation even in the presence of artifacts associated with processing issues that were recorded as high as 50.7 % for processor C. The occurrence of background non-specific staining and the presence of false positive results appear to be unrelated with the PD-L1 clone or the type of tissue processing. 22C3 PD-L1 was more frequently considered adequate for evaluation than SP142 PD-L1 that, in 29.2 % of WSIs (after tissue processor C) were considered not adequate for observation due to lack of the typical pattern of expression. Similarly, the intensity of PD-L1 staining was significantly decreased in fragments processed by C (both PD-L1 clones) in tonsil and placenta specimens, and by A (both clones) in comparison with those processed by B. This study demonstrates the need to standardize the tissue processing in pathology to cope with the growing needs of precision medicine quantifications and the production of high-quality material necessary for computational pathology usage.

Background and surrounding colors affect the color blending of a single-shade composite.

This study evaluated the background and effect of surrounding colors on the color blending of a single-shade composite used in a thin layer. Disc-shaped specimens (1.0 mm thickness) were built with the Vittra APS Unique composite surrounded (dual specimens) or not surrounded (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens were also built with only control composites. The specimen color was measured against white and black backgrounds with a spectrophotometer (CIELAB system). The whiteness index for dentistry (WID) was calculated for simple specimens. Differences (ΔE00) in color and translucency parameters (ΔTP00) between the simple/dual specimens and the controls were calculated. The translucency adjustment potential (TAP) and color adjustment potential (CAP) were estimated based on the ratios between data from simple and dual specimens. The Vittra APS Unique composite showed higher WID values than the controls. No differences between ΔTP00_SIMPLE and ΔTP00_DUAL were observed for any of the shades. The composite shade did not affect TAP values. The lowest values of ΔE00_SIMPLE and ΔE00_DUAL were observed for shade A1 regardless of the background color. For the white background, ΔE00_SIMPLE values did not differ from those of ΔE00_DUAL for all shades. Only A1 showed ΔE00_DUAL values lower than ΔE00_SIMPLE when the black background was used. The highest modulus of CAP (negative values for the white background) was observed when shade A1 surrounded the Vittra APS Unique composite. The color blending ability of the single-shade resin composite used in a thin layer was affected by both the surrounding shade and background color.

Factors associated with covid-19 deaths in the city of Recife, Pernambuco, Brazil, 2020: a cross-sectional study with "Notifique Aqui" system data.

OBJECTIVE: to analyze the clinical conditions and sociodemographic characteristics associated with covid-19 deaths in the first year of the pandemic in the city of Recife, Pernambuco, Brazil, 2020. METHODS: this was a cross-sectional study with covid-19-induced severe acute respiratory syndrome cases recorded in 2020 via the "Notifique Aqui" (Report Here) electronic system of the Pernambuco Center for Strategic Information on Health Surveillance. Association between death and sociodemographic and clinical variables was analyzed. Prevalence ratios (PR) with 95% confidence intervals (95%CI) were calculated using adjusted Poisson regression. RESULTS: the prevalence of death was 28.4% (2,833 cases; 95%CI 27.51;29.28). The associated factors were male sex (PR = 1.05; 95%CI 1.01;1.08), age ≥ 60 years (PR = 0.76; 95%CI 0.72;0.79), dyspnea (PR = 1.06; 95%CI 1.02;1.10), respiratory distress (PR = 1.06; 95%CI 1.03;1.09), oxygen saturation < 95% (PR = 1.08; 95%CI 1.04;1.11) and chronic diseases. CONCLUSION: covid-19 deaths were more prevalent among male, older adults, and people with pre-existing health problems, these being priority groups for combating the pandemic.

Effects of surrounding and underlying shades on the color adjustment potential of a single-shade composite used in a thin layer.

Objectives: This study aimed to evaluate the surrounding and underlying shades' effect on the color adjustment potential (CAP) of a single-shade composite used in a thin layer. Materials and Methods: Cylinder specimens (1.0 mm thick) were built with the Vittra APS Unique composite, surrounded (dual specimens) or not (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens were also built only with the control composites. Each specimen's color was measured against white and black backgrounds or the simple control specimens with a spectrophotometer (CIELAB system). The whiteness index for dentistry (WID) and translucency parameters (TP00) were calculated for simple specimens. Differences (ΔE00) in color between the simple/dual specimens and the controls were calculated. The CAP was calculated based on the ratios between data from simple and dual specimens. Results: The Vittra APS Unique composite showed higher WID and TP00 values than the controls. The highest values of ΔE00 were observed among simple specimens. The color measurements of Vittra APS Unique (simple or dual) against the control specimens presented the lowest color differences. Only surrounding the single-shade composite with a shaded composite barely impacted the ΔE00. The highest CAP values were obtained using a shaded composite under simple or dual specimens. Conclusions: The CAP of Vittra APS Unique was strongly affected by the underlying shade, while surrounding this composite with a shaded one barely affected its color adjustment.

COMT rs4818 less common allele is associated with psychological and psychiatric worse indicators in a cohort of individuals born with cleft lip and palate.

OBJECTIVE: Individuals born with cleft lip and palate may face difficulties in speech function, nutrition, facial aesthetics, and long-term care. These difficulties may increase the risk of psychological and psychiatric diseases. This work aimed to test if the variant allele of COMT was carried more frequently among individuals that have psychological and psychiatric outcomes within a cohort of patients born with cleft lip and palate. METHOD: DNA extraction from saliva of two hundred and fifteen individuals born with cleft lip with and/or palate and genotyping was performed, and the frequency of COMT rs4818 alleles was determined. The domain 'Psychological Function' of Cleft-Q™ was used to generate scores for analysis. The scores were computed, and differences in genotype or allele frequencies between individuals with psychological function scores 60 or above and 59 or below were compared. The history of psychiatric illness (family history of psychiatric disease or self-reported psychiatric illness) was registered. RESULTS: Genotype and allele frequencies were compared between individuals with and without a family history of psychiatric illness. Individuals with lower Psychological Function (Cleft-Q™) scores were more likely to be GG (P = .04) or carriers of allele G (P < .001). The reported psychiatric illness and positive family history of psychiatric illness were compared to COMT rs4818 allele and genotype frequencies of individuals without these indicators, and individuals with psychiatric illness and positive family history of psychiatric illness were more likely to carry allele G (P = .03 and P = .008, respectively). CONCLUSION: The study confirms previously suggested role of COMT rs4818 in psychiatric and psychological outcomes in a distinct cohort of patients born with cleft lip and palate.

Background and surrounding colors affect the color blending of a single-shade composite

Abstract This study evaluated the background and effect of surrounding colors on the color blending of a single-shade composite used in a thin layer. Disc-shaped specimens (1.0 mm thickness) were built with the Vittra APS Unique composite surrounded (dual specimens) or not surrounded (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens were also built with only control composites. The specimen color was measured against white and black backgrounds with a spectrophotometer (CIELAB system). The whiteness index for dentistry (WID) was calculated for simple specimens. Differences (ΔE00) in color and translucency parameters (ΔTP00) between the simple/dual specimens and the controls were calculated. The translucency adjustment potential (TAP) and color adjustment potential (CAP) were estimated based on the ratios between data from simple and dual specimens. The Vittra APS Unique composite showed higher WID values than the controls. No differences between ΔTP00_SIMPLE and ΔTP00_DUAL were observed for any of the shades. The composite shade did not affect TAP values. The lowest values of ΔE00_SIMPLE and ΔE00_DUAL were observed for shade A1 regardless of the background color. For the white background, ΔE00_SIMPLE values did not differ from those of ΔE00_DUAL for all shades. Only A1 showed ΔE00_DUAL values lower than ΔE00_SIMPLE when the black background was used. The highest modulus of CAP (negative values for the white background) was observed when shade A1 surrounded the Vittra APS Unique composite. The color blending ability of the single-shade resin composite used in a thin layer was affected by both the surrounding shade and background color.

Abstract Objective To validate the Youth Empowerment Through Health Education Scale (EJEduS) content and appearance after an educational intervention. Methods This is a methodological study carried out through EJEduS assessment by relevance, clarity and pertinence criteria by experts in the subject as well as by school adolescents and from a quilombola community. The analysis was performed using the Content Validity Coefficient and Content Validity Index, in addition to calculating the Gwet AC2 to verify inter- and intra-expert agreement. Results Of the initial 50 items on the scale, 18 needed to be reformulated and 11 were excluded after consensus discussion with adolescents. The intra-expert agreement was almost perfect for the three criteria: relevance (Gwet: 0.894; 95%CI 0.825-0.919), clarity (Gwet: 0.848; 95%CI 0.816-0.879) and pertinence (Gwet: 0.896; 95%CI 0.870-0.923). In the intra-adolescent agreement analysis, an almost perfect agreement was observed (Gwet: 0.96; 95%CI 0.917-1), with acceptable agreement rates of Content Validity Coefficient and Content Validity Index, both with 0.91. Conclusion The scale presented satisfactory Content Validity Indexes and appearance to measure youth empowerment through health education.

Youth empowerment in health: a theoretical structure of literacy practices / Empoderamiento de los jóvenes en salud: una estructura teórica de las prácticas de alfabetización / Empoderamento juvenil em saúde: uma estrutura teórica das práticas de letramento

ABSTRACT Objective: To develop a theoretical structure on literacy practices committed to health empowerment, based on the understanding of school adolescents and members of a Quilombola community in the State of Pernambuco, Brazil. Method: Interpretative analysis, based on the assumptions of the Grounded Theory and Symbolic Interactionism. For data collection, Culture Circles were conducted with 18 adolescents from October 2020 to August 2021. Results: The theoretical archetype is structured based on the recognition of vulnerable youth context, and the development of potential through collective relations built by dialogue, trust, shared knowledge construction, and the use of technologies. Final considerations: The theoretical structure on literacy practices committed to empowerment through the understanding of adolescents runs through the framework of a substantive theory that culminates in a perspective of agency and recognition of their needs.

Fatores associados ao óbito por covid-19 em Recife, Pernambuco, 2020: estudo transversal com dados do sistema "Notifique Aqui" / Factores asociados a la muerte por covid-19 en la ciudad de Recife, Pernambuco, Brasil, 2020: un estudio transversal con datos del sistema "Notifique Aqui" / Factors associated with covid-19 deaths in the city of Recife, Pernambuco, Brazil, 2020: a cross-sectional study with "Notifique Aqui" system data

Objetivo: analisar condições clínicas e características sociodemográficas associadas ao óbito por covid-19 no primeiro ano da pandemia em Recife, Pernambuco, Brasil, 2020. Métodos: estudo transversal, sobre casos de síndrome respiratória aguda grave por covid-19 registrados no Centro de Informações Estratégicas de Vigilância em Saúde de Pernambuco, via sistema eletrônico "Notifique Aqui"; analisou-se a associação do óbito com variáveis sociodemográficas e clínicas; razões de prevalências (RP) com intervalos de confiança de 95% (IC95%) foram calculadas por regressão de Poisson ajustada. Resultados: prevalência do óbito de 28,4% (2.833 casos; IC95% 27,51;29,28); sexo masculino (RP = 1,05; IC95% 1,01;1,08), idade ≥ 60 anos (RP = 0,76; IC95% 0,72;0,79), dispneia (RP = 1,06; IC95% 1,02;1,10), desconforto respiratório (RP = 1,06; IC95% 1,03;1,09), saturação de oxigênio < 95% (RP = 1,08; IC95% 1,04;1,11) e doenças crônicas revelaram-se fatores associados. Conclusão: o óbito por covid-19 foi mais prevalente entre sexo masculino, idosos, pessoas com problemas de saúde preexistentes - grupos prioritários no enfrentamento à pandemia.

Objetivo: analizar las condiciones clínicas y características sociodemográficas asociadas a la muerte por covid-19 en el primer año de la pandemia en la ciudad de Recife. Métodos: estudio transversal con casos de síndrome respiratorio agudo severo por covid-19 registrados en 2020 a través del sistema electrónico "Notifique Aquí" del Centro de Información Estratégica de Vigilancia en Salud de Pernambuco. Se analizó la asociación entre la muerte y variables sociodemográficas y clínicas.

Sexo masculino (CP = 1,05; IC95% 1,01;1,08), edad ≥60 años (CP = 0,76; IC95% 0,72;0,79), disnea (CP = 1,06; IC95% 1,02;1,10), dificultad respiratoria (CP = 1,06; IC95% 1,03;1,09) y saturación de oxígeno < 95% (CP = 1,08; IC95% 1,04;1,11) y enfermedades crónicas fueron factores asociados. Conclusión: la muerte por covid-19 fue más prevalente entre hombres, ancianos y personas con problemas de salud preexistentes, grupos prioritarios en el enfrentamiento a la pandemia.

Objective: to analyze the clinical conditions and sociodemographic characteristics associated with covid-19 deaths in the first year of the pandemic in the city of Recife, Pernambuco, Brazil, 2020. Methods: this was a cross-sectional study with covid-19-induced severe acute respiratory syndrome cases recorded in 2020 via the "Notifique Aqui" (Report Here) electronic system of the Pernambuco Center for Strategic Information on Health Surveillance. Association between death and sociodemographic and clinical variables was analyzed. Prevalence ratios (PR) with 95% confidence intervals (95%CI) were calculated using adjusted Poisson regression. Results: the prevalence of death was 28.4% (2,833 cases; 95%CI 27.51;29.28). The associated factors were male sex (PR = 1.05; 95%CI 1.01;1.08), age ≥ 60 years (PR = 0.76; 95%CI 0.72;0.79), dyspnea (PR = 1.06; 95%CI 1.02;1.10), respiratory distress (PR = 1.06; 95%CI 1.03;1.09), oxygen saturation < 95% (PR = 1.08; 95%CI 1.04;1.11) and chronic diseases. Conclusion: covid-19 deaths were more prevalent among male, older adults, and people with pre-existing health problems, these being priority groups for combating the pandemic.
