Three New Isoprenylated Flavones from Artocarpus chama Stem and Their Bioactivities

Phytochemical investigation of Artocarpus chama stem was performed by chromatographic techniques, resulting from the isolation and structure elucidation of three new compounds, namely 3′-farnesyl-apigenin (1), 3-(hydroxyprenyl) isoetin (2), and 3-prenyl-5,7,2′,5′-tetrahydroxy-4′-methoxyflavone (3), and five known compounds, namely homoeriodictyol (4), isocycloartobilo-xanthone (5), artocarpanone (6), naringenin (7), and artocarpin (8). From the screening result, A. chama extract showed a potent tyrosinase inhibitory effect. Ihe isolated compounds 1, 4 and 6 also exhibited tyrosinase inhibition with IC50 of 135.70, 52.18, and 38.78 µg/mL, respectively. Moreover, compounds 3, 4, 5, 6, and 8 showed strong activity against Staphylococcus epidermidis, S. aureus, methicillin-resistant S. aureus, and Cutibacterium acnes. This study is the first report on phytochemical investigation with new compounds and biological activities of A. chama. Skin infection can cause dark spots or hyperpigmentation. The isolated compounds that showed both anityrosinase and antimicrobial activities will be further studied in in vivo and clinical trials in order to develop treatment for hyperpigmentation, which is caused by infectious diseases by microorganisms.

Pulmonary tuberculosis among prisoners in Southern Thailand: prevalence and its association with imprisonment status

Purpose This study aims to measure the prevalence of pulmonary tuberculosis (PTB), its association with imprisonment status and to document the treatment success rate (TSR) among prisoners in Songkhla province, Southern Thailand. Design/methodology/approach A retrospective cross-sectional study was conducted in five prisons in Songkhla province, including all prisoners in the fiscal of year 2019, who had an annual chest radiography (CXR) screening result. Information of prisoners who had been imprisoned from 1 October 2018 to 30 September 2019, were reviewed for PTB diagnosis. Imprisonment status and other associated factors with PTB were analyzed using multiple logistic regression. Findings The prevalence of PTB was 2.72%. Prisoners having new or transfer-in status were more likely to have PTB. Those aged 40–80 years, who had smoked for ten years or more, or who were underweight, had higher odds of having PTB. TSR among prisoners with PTB in this study was 94.9%. Originality/value The prevalence of PTB among prisoners having annual CXR screening was high. Detection of PTB was higher among new or transfer-in prisoners; therefore, the CXR for PTB screening before admission to prison should be performed to prevent transmission to other prisoners.

↵​A Copro-parasitological Surveillance on Diverse Captive Wild Avian Species

Background: Infections with gastrointestinal parasites are widespread and a major health issue for captive birds. Despite the significance being well known, not much studies have been conducted on its prevalence especially in captive avians in a zoo setup. The present study aims at determining the prevalence of parasites in captive birds of different orders maintained at Bannerghatta Biological Park, Bengaluru, Karnataka. Methods: In this investigation, a survey through fecal sample examination was conducted to assess the parasitic infection in captive birds belonging to 6 different biological orders e.g. Casuariiformes, Anseriformes, Galliformes, Pelecaniformes, Psittaciformes {Emu (Dromaius novaehollandiae), Duck (Anas platyrhynchos), Peafowl (Pavo cristatus), red jungle fowl (Gallus gallus), grey pelican, (Pelecanus philippensis), purple heron (Ardea purpurea), silver pheasant (Lophura nycthemera), macaw (Ara ararauna), parakeet (Psittacula eupatsia)} and Ciconiiformes maintained at Bannerghatta Biological Park, Bengaluru, Karnataka. A total of 106 fecal samples from apparently healthy birds including 7 samples from emu, 3 ducks, 12 peafowls, 8 red jungle fowls, 24 grey pelicans, 1 purple heron, 13 silver pheasants, 8 macaws, 26 parakeets and 4 Indian open-billed storks were collected during 2015-2016 and were screened for parasitic eggs/oocysts. Result: The screening result could detect ova of 2 (28.57%) Eimeria oocyst in emu, 3 (100%) Eimeria oocyst in duck, 7 (58.33%) Capillaria sp., 3 (25%) Eimeria oocyst, 2 (16.66%) Ascardia galli, 2 (16.66%) Raillietina echinobothrida, 1 (8.33%) Tetrameres sp. in peafowls, 3 (37.5%) Ascardia galli, 1 (12.5%) Eimeria oocyst in red jungle fowls, 5 (20.83%) Ascardia galli in grey pelican, 1 (100%) trematode ova in purple heron, 3 (23.07%) Raillietina sp., 2 (15.38%) Eimeria ocyst in silver pheasant, 2 (25%) Ascaris sp. in macaw, 12 (46.15%) Ascaris sp., 3 (11.53%) Eimeria oocyst in parakeet and 4 (100%) Tetrameres sp. in Indian open-billed storks.

Process evaluation of co-designed interventions to improve communication of positive newborn bloodspot screening results

ObjectiveTo implement and evaluate co-designed interventions to improve communication of positive newborn bloodspot screening results and make recommendations for future research and practice.DesignA process evaluation underpinned by Normalisation Process Theory.SettingThree National Health Service provider organisations in England.ParticipantsTwenty-four healthcare professionals (7 newborn screening laboratory staff and 24 clinicians) and 18 parents were interviewed.InterventionsThree co-designed interventions were implemented in practice: standardised laboratory proformas, communication checklists and an email/letter template.Primary outcome measuresAcceptability and feasibility of the co-designed interventions.ResultsAuditing the implementation of these interventions revealed between 58%–76% of the items on the laboratory proforma and 43%–80% of items on the communication checklists were completed. Interviews with healthcare professionals who had used the interventions in practice provided positive feedback in relation to the purpose of the interventions and the ease of completion both of which were viewed as enhancing communication of positive newborn bloodspot screening results. Interviews with parents highlighted the perceived benefit of the co-designed interventions in terms of consistency, pacing and tailoring of information as well as providing reliable information to families following communication of the positive newborn bloodspot screening result. The process evaluation illuminated organisational and contextual barriers during implementation of the co-designed interventions in practice.ConclusionVariations in communication practices for positive newborn bloodspot screening results continue to exist. The co-designed interventions could help to standardise communication of positive newborn screening results from laboratories to clinicians and from clinicians to parents which in turn could improve parents’ experience of receiving a positive newborn bloodspot screening result. Implementation highlighted some organisational and contextual barriers to effective adoption of the co-designed interventions in practice.Trial registration numberISRCTN15330120.

Oropharyngeal Dysphagia After Hospitalization for COVID-19 Disease: Our Screening Results

A high percentage of patients suffered symptoms also after recovery from the Coronavirus Disease—2019 (COVID-19) infection. It is not well clear what are the specific long-term sequelae (complications and symptoms). During the acute phase the patients may develop a multi-organ system pathology including aerodigestive tract. As the pathophysiology of COVID-19 emerges, the aim of our study was to describe the prevalence of oropharyngeal dysphagia after COVID-19 disease. From March to July 2020 we enrolled patients recovered from SARS-CoV-2 infection who had been previously hospitalized for the disease. They were screened for dysphagia by mean of the Eating Assessment Tool-10 (EAT-10). The cases with EAT-10 score > 3 were graded for the aspiration risk by applying the Gugging Swallowing Screen (GUSS) and were submitted to the Swal-QoL questionnaire. The cases with a GUSS score > 19 were subjected to FEES. 8/117 (7%) patients had positive screening result. 4/8 (50%) revealed an abnormal health related quality of life in oropharyngeal dysphagia with a mean Swal-QoL score of 69.73. The most affected domain was the “time of meals” (mean score 65) following by the “sleep” (mean score 66) and “eating desire” (mean score 72). 1/8 cases showed increased risk for aspiration and did not showed endoscopic signs of oropharyngeal dysphagia. Our results showed that the prevalence of upper dysphagia after hospitalization for SARS-CoV-2 is not anecdotal and that probably this long-lasting sequela has a psychogenic etiology.

Short and long-term psychosocial consequences of participating in a colorectal cancer screening programme: a matched longitudinal study

ObjectivesTo investigate the psychosocial consequences of receiving a false-positive (no abnormalities) result or being diagnosed with polyps compared with receiving a negative result in a colorectal cancer (CRC) screening programme.Design and settingThis was a longitudinal study nested in the roll-out of the Danish CRC screening programme that targets all individuals aged 50–74 years.ParticipantsIn the inclusion period (April–September 2017), all positive screenees (n=1854) were consecutively enrolled and matched 2:1:1 on sex, age (±2 years), municipality and screening date with negative screenees (n=933) and individuals not yet invited to screening (n=933).Questionnaires were sent by mail to all eligible participants in Region Zealand, Denmark, after the screening result, 2 months and 12 months after the final result.Positive screenees who did not receive the follow-up procedure were excluded.Main outcome measuresThe primary outcomes were psychosocial consequences. Outcomes were measured with the CRC screening-specific questionnaire Consequences of screening in CRC with 11 outcomes after the screening result and with 21 outcomes at the two later assessments.ResultsAfter receiving the screening result, individuals with no abnormalities, low-risk and medium-risk and high-risk polyps scored significantly worse on 8 of 11 outcomes compared with the negative screenee group. At the 12-month follow-up, the differences were still significant in 8 of 21 outcomes (no abnormalities), 4 of 21 outcomes (low-risk polyps) and 10 of 21 outcomes (medium-risk and high-risk polyps). The negative screenee group and the group not yet invited to screening differed psychosocially on 5 of 11 outcomes after the screening result, but on none of the 21 outcomes at the 2 months and 12 months follow-up.ConclusionsThe study showed that there are both short-term and long-term psychosocial consequences associated with receiving a no abnormalities result or being diagnosed with polyps. The consequences were worst for individuals diagnosed with medium-risk and high-risk polyps.
