Autophagy, a self-defense mechanism, has been found to be associated with drug resistance in hepatocellular carcinoma (HCC). Our study was designed to investigate the role and related mechanisms of autophagy in matrine-induced apoptosis in hepatoma cells of HepG2 and Bel7402. Cell apoptosis was detected by flow cytometry analysis (Annexin V–FITC/PI double-staining assay), the activity and activating cleavages of caspase-3, -8, and -9. MTT assay and colony forming assay were used to assess the effect of matrine on growth and proliferation of HCC cells. Autophagic flux in HCC cells was analyzed using the expression of LC3BI/II and p62/SQSTM1, GFP-LC3 transfection, and transmission electron microscopy. Moreover, regarding to the associated mechanisms, the effects of matrine on the phosphoinositide 3-kinase/AKT/mTOR pathway and beclin-1 were studied. Our results showed that: (1) both autophagy and apoptosis could be induced by treatment with matrine; (2) using the autophagic inhibitor chloroquine and beclin-1 small-interfering RNA, cell apoptosis induced by matrine could be enhanced in a caspase-dependent manner; and (3) autophagy was induced via inhibition of PI3K/AKT/mTOR pathway and up-regulation of beclin-1. In conclusion, inhibition of autophagy could enhance matrine-induced apoptosis in human hepatoma cells.

Publisher: Institute of Electrical and Electronics Engineers (IEEE)This correspondence presents a new recursive formulation of Toom's algorithm that allows the generation of higher order (longer size) one-dimensional (1-D) convolution architectures from three lower order (shorter sizes) convolution architectures. Our methodology is based on manipulating tensor product forms so that they can be mapped directly into modular parallel architectures. The resulting convolution circuits have very simple modular structure and regular topology.

Inflammation is a natural clinical repair response of body’s immune system to protect its tissues from various noxious stimuli that continues to remodel throughout the lifecycle because of interactions between genes, lifestyles, and environments. There is a link between inflammation, elevated plasma homocysteine levels and cardiometabolic diseases. Multiple mechanisms have been proposed through which homocysteine can modulate the inflammatory response, though the exact mechanism is not clearly understood. The serum homocysteine concentration is considered as an independent risk factor for many disease conditions including cardiovascular diseases (CVD). Epidemiological evidence indicates that moderate consumption of anthocyanins is associated with reduced risk of atherosclerosis and cardiovascular diseases. However, a clear relationship between anthocyanin and homocysteine has not yet been developed. Anthocyanins are water soluble blue, red, and purple pigments, present in the vacuolar sap of the epidermal tissues of plant parts. As therapeutic agents, they are well-accepted in folk medicine worldwide and are linked to a myriad of health benefits. Anthocyanins impart an amazing role in lessening inflammation in body tissues. The molecular mechanisms involved in anti-inflammatory activities include inhibition of pro-inflammatory enzymes, such as cyclooxygenase-2, lipoxygenase and inducible nitric oxide (NO) synthase, inhibition of NF-kB and activating protein-1 (AP-1) and activation of phase II antioxidant detoxifying enzymes, mitogen-activated protein kinase (MAPK), protein kinase C and nuclear factor-erythroid 2-related factor 2. This chapter discusses the interrelationship between hyperhomocysteinemia, inflammation and anthocyanins, as well as the mechanisms of action and anti-inflammatory role of anthocyanins in the prevention of cardiometabolic diseases.

ObjectiveTo evaluate whether the clinical benefit and relapse rates in anti-muscle-specific kinase (MuSK) myasthenia gravis (MG) differ depending on the protocol of rituximab followed. MethodsThis retrospective multicentre study in patients with MuSK MG compared three rituximab protocols in terms of clinical status, relapse, changes in treatment, and adverse side effects. The primary effectiveness endpoint was clinical relapse requiring a further infusion of rituximab. Survival curves were estimated using Kaplan-Meier methods and survival analyses were undertaken using Cox proportional-hazards models. ResultsTwenty-five patients were included: 11 treated with protocol 4 + 2 (375 mg/m(2)/4 weeks, then monthly for 2 months), five treated with protocol 1 + 1 (two 1 g doses 2 weeks apart), and nine treated with protocol 4 (375 mg/m(2)/4 weeks). Mean follow-up was 5.0 years (SD 3.3). Relapse occurred in 18.2%, 80%, and 33.3%, and mean time to relapse was 3.5 (SD 1.5), 1.1 (SD 0.4), and 2.5 (SD 1.4) years, respectively. Based on Kaplan-Meier estimates, patients treated with protocol 4 + 2 had fewer and later relapses than patients treated with the other two protocols (log-rank test P = 0.0001). Patients treated with protocol 1 + 1 had a higher risk of relapse than patients treated with protocol 4 + 2 (HR 112.8, 95% CI, 5.7-2250.4, P = 0.002). Patients treated with protocol 4 showed a trend to a higher risk of relapse than those treated with protocol 4 + 2 (HR 9.2, 95% CI 0.9-91.8, P = 0.059). InterpretationThis study provides class IV evidence that the 4 + 2 rituximab protocol has a lower clinical relapse rate and produces a more durable response than the 1 + 1 and 4 protocols in patients with MuSK MG.

Publisher: Elsevier BVAbstractThere is now widespread acceptance of the universal coverage approach, presented in the 2010 World Health Report. There are more and more voices for the benefit of creating a single national risk pool. Now, a body of literature is emerging on institutional design and organizational practice for universal coverage, related to management of the three health-financing functions: collection, pooling and purchasing. While all countries can move towards universal coverage, lower-income countries face particular challenges, including scarce resources and limited capacity. Recently, the Lao PDR has been preparing options for moving to a single national health insurance scheme. The aim is to combine four different social health protection schemes into a national health insurance authority (NHIA) with a single national fund- and risk-pool. This paper investigates the main institutional and organizational challenges related to the creation of the NHIA. The paper uses a qualitative approach, drawing on the World Health Organization's institutional and Organizational Assessment for Improving and Strengthening health financing (OASIS) conceptual framework for data analysis. Data were collected from a review of key health financing policy documents and from 17 semi-structured key informant interviews. Policy makers and advisors are confronting issues related to institutional arrangements, funding sources for the authority and government support for subsidies to the demand-side health financing schemes. Compulsory membership is proposed, but the means for covering the informal sector have not been resolved. While unification of existing schemes may be the basis for creating a single risk pool, challenges related to administrative capacity and cross-subsidies remain. The example of Lao PDR illustrates the need to include consideration of national context, the sequencing of reforms and the time-scale appropriate for achieving universal coverage.

AbstractOnly a few studies have assessed the long-term duration of the humoral immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).In this nationwide longitudinal study from the Faroe Islands with close to full participation of all individuals on the Islands with PCR confirmed COVID-19 during the two waves of infections in the spring and autumn 2020 (n=172 & n=233), samples were drawn at three longitudinal time points (3, 7 and 12 months and 1, 3 and 7 months after disease onset, respectively).Serum was analyzed with a direct quantitative IgG antibody binding ELISA to detect anti–SARS-CoV-2 spike RBD antibodies and a commercially available qualitative sandwich RBD ELISA kit measuring total antibody binding.The seropositive rate in the convalescent individuals was above 95 % at all sampling time points for both assays. There was an overall decline in IgG titers over time in both waves (p < 0.001). Pairwise comparison showed that IgG declined significantly from the first sample until approximately 7 months in both waves (p < 0.001). After that, the antibody level still declined significantly (p < 0.001), but decelerated with an altered slope remaining fairly stable from 7 months to 12 months after infection. Interestingly, the IgG titers followed a U-shaped curve with higher antibody levels among the oldest (67+) and the youngest (0– 17) age groups compared to intermediate groups (p < 0.001).Our results indicate that COVID-19 convalescent individuals are likely to be protected from reinfection up to 12 months after symptom onset and maybe even longer. We believe our results can add to the understanding of natural immunity and the expected durability of SARS-CoV-2 vaccine immune responses.

Publisher: Cambridge University Press (CUP)Country: TurkeyAbstractObjectiveWhen patients feel spiritually supported by staff, we find increased use of hospice and reduced use of aggressive treatments at end of life, yet substantial barriers to staff spiritual care provision still exist. We aimed to study these barriers in a new cultural context and analyzed a new subgroup with “unrealized potential” for improved spiritual care provision: those who are positively inclined toward spiritual care yet do not themselves provide it.MethodWe distributed the Religion and Spirituality in Cancer Care Study via the Middle East Cancer Consortium to physicians and nurses caring for advanced cancer patients. Survey items included how often spiritual care should be provided, how often respondents themselves provide it, and perceived barriers to spiritual care provision.ResultWe had 770 respondents (40% physicians, 60% nurses) from 14 Middle Eastern countries. The results showed that 82% of respondents think staff should provide spiritual care at least occasionally, but 44% provide spiritual care less often than they think they should. In multivariable analysis of respondents who valued spiritual care yet did not themselves provide it to their most recent patients, predictors included low personal sense of being spiritual (p< 0.001) and not having received training (p= 0.02; only 22% received training). How “developed” a country is negatively predicted spiritual care provision (p< 0.001). Self-perceived barriers were quite similar across cultures.Significance of resultsDespite relatively high levels of spiritual care provision, we see a gap between desirability and actual provision. Seeing oneself as not spiritual or only slightly spiritual is a key factor demonstrably associated with not providing spiritual care. Efforts to increase spiritual care provision should target those in favor of spiritual care provision, promoting training that helps participants consider their own spirituality and the role that it plays in their personal and professional lives.

Publisher: Nagoya UniversityABSTRACT In Lao People’s Democratic Republic (Lao PDR), reports on disease frequency are very limited. This study aimed to report frequencies of the main cause of admission among inpatients of a tertiary general hospital (Mittaphab Hospital) in Vientiane. Subjects were inpatients who were admitted from January 3 to February 2 in 2017. The dataset were made as a pilot run to establish hospital statistics. The data on sex, age, address (province), dates of admission and discharge, and main diagnosis were collected from paper-based medical charts. International Classification of Diseases 10 was applied for classifying the main diagnosis. During the 1-month period, 1,201 inpatients (637 males and 564 females) were admitted, including 171 (14.2%) aged <20 years and 254 (21.1%) aged ≥60 years. About 20% patients were from outside of Vientiane. Among them, 67.5% (62.5% in males and 73.8% in females) were admitted within 7 days. The main causes with more than 10% in males were injury and poisoning S00-T98 (49.8%), while those in females were injury and poisoning S00-T98 (25.2%), pregnancy and childbirth O00-O99 (19.0%), and diseases of genitourinary system N00-N99 (13.7%). Injury and poisoning S00-T98 among inpatients aged <20 years was 81.8% in males and 59.0% in females. Among those aged 20–59 years, it was 49.9% and 22.4%, and among those aged ≥60 years it was 22.3% and 16.9%, respectively. This is the first report on the frequencies of main diseases among inpatients in Lao PDR. Injury was the first main cause of admission at the tertiary hospital.

Abstract Background Testing for HIV at birth has the potential to identify infants infected in utero, and allows for the possibility of beginning treatment immediately after birth; point of care (POC) testing allows rapid return of results and faster initiation on treatment for positive infants. Eswatini piloted birth testing in three public maternities for over 2 years. Methods In order to assess the acceptability of POC birth testing in the pilot sites in Eswatini, interviews were held with caregivers of HIV-exposed infants who were offered birth testing (N = 28), health care workers (N = 14), and policymakers (N = 10). Participants were purposively sampled. Interviews were held in English or SiSwati, and transcribed in English. Transcripts were coded by line, and content analysis and constant comparison were used to identify key themes for each respondent type. Results Responses were categorized into: knowledge, experience, opinions, barriers and challenges, facilitators, and suggestions to improve POC birth testing. Preliminary findings reveal that point of care birth testing has been very well received but challenges were raised. Most caregivers appreciated testing the newborns at birth and getting results quickly, since it reduced anxiety of waiting for several weeks. However, having a favorable experience with testing was linked to having supportive and informed family members and receiving a negative result. Caregivers did not fully understand the need for blood draws as opposed to tests with saliva, and expressed the fears of seeing their newborns in pain. They were specifically grateful for supportive nursing staff who respected their confidentiality. Health care workers expressed strong support for the program but commented on the high demand for testing, increased workload, difficulty with errors in the testing machine itself, and struggles to implement the program without sufficient staffing, especially on evenings and weekends when phlebotomists were not available. Policymakers noted that there have been challenges within the program of losing mothers to follow up after they leave hospital, and recommended stronger linkages to community groups. Conclusions There is strong support for scale-up of POC birth testing, but countries should consider ways to optimize staffing and manage demand.

The aim is to combine four different social health protection schemes into a national health insurance authority (NHIA) with a single national fund- and risk-pool. This paper investigates the main institutional and organizational challenges related to the creation of the NHIA. The paper uses a qualitative approach, drawing on the World Health Organization's institutional and Organizational Assessment for Improving and Strengthening health financing (OASIS) conceptual framework for data analysis. Data were collected from a review of key health financing policy documents and from 17 semi-structured key informant interviews. Policy makers and advisors are confronting issues related to institutional arrangements, funding sources for the authority and government support for subsidies to the demand-side health financing schemes. Compulsory membership is proposed, but the means for covering the informal sector have not been resolved. While unification of existing schemes may be the basis for creating a single risk pool, challenges related to administrative capacity and cross-subsidies remain. The example of Lao PDR illustrates the need to include consideration of national context, the sequencing of reforms and the time-scale appropriate for achieving universal coverage.

AbstractOnly a few studies have assessed the long-term duration of the humoral immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).In this nationwide longitudinal study from the Faroe Islands with close to full participation of all individuals on the Islands with PCR confirmed COVID-19 during the two waves of infections in the spring and autumn 2020 (n=172 & n=233), samples were drawn at three longitudinal time points (3, 7 and 12 months and 1, 3 and 7 months after disease onset, respectively).Serum was analyzed with a direct quantitative IgG antibody binding ELISA to detect anti–SARS-CoV-2 spike RBD antibodies and a commercially available qualitative sandwich RBD ELISA kit measuring total antibody binding.The seropositive rate in the convalescent individuals was above 95 % at all sampling time points for both assays. There was an overall decline in IgG titers over time in both waves (p < 0.001). Pairwise comparison showed that IgG declined significantly from the first sample until approximately 7 months in both waves (p < 0.001). After that, the antibody level still declined significantly (p < 0.001), but decelerated with an altered slope remaining fairly stable from 7 months to 12 months after infection. Interestingly, the IgG titers followed a U-shaped curve with higher antibody levels among the oldest (67+) and the youngest (0– 17) age groups compared to intermediate groups (p < 0.001).Our results indicate that COVID-19 convalescent individuals are likely to be protected from reinfection up to 12 months after symptom onset and maybe even longer. We believe our results can add to the understanding of natural immunity and the expected durability of SARS-CoV-2 vaccine immune responses.

Publisher: Cambridge University Press (CUP)Country: TurkeyAbstractObjectiveWhen patients feel spiritually supported by staff, we find increased use of hospice and reduced use of aggressive treatments at end of life, yet substantial barriers to staff spiritual care provision still exist. We aimed to study these barriers in a new cultural context and analyzed a new subgroup with “unrealized potential” for improved spiritual care provision: those who are positively inclined toward spiritual care yet do not themselves provide it.MethodWe distributed the Religion and Spirituality in Cancer Care Study via the Middle East Cancer Consortium to physicians and nurses caring for advanced cancer patients. Survey items included how often spiritual care should be provided, how often respondents themselves provide it, and perceived barriers to spiritual care provision.ResultWe had 770 respondents (40% physicians, 60% nurses) from 14 Middle Eastern countries. The results showed that 82% of respondents think staff should provide spiritual care at least occasionally, but 44% provide spiritual care less often than they think they should. In multivariable analysis of respondents who valued spiritual care yet did not themselves provide it to their most recent patients, predictors included low personal sense of being spiritual (p< 0.001) and not having received training (p= 0.02; only 22% received training). How “developed” a country is negatively predicted spiritual care provision (p< 0.001). Self-perceived barriers were quite similar across cultures.Significance of resultsDespite relatively high levels of spiritual care provision, we see a gap between desirability and actual provision. Seeing oneself as not spiritual or only slightly spiritual is a key factor demonstrably associated with not providing spiritual care. Efforts to increase spiritual care provision should target those in favor of spiritual care provision, promoting training that helps participants consider their own spirituality and the role that it plays in their personal and professional lives.

Publisher: Nagoya UniversityABSTRACT In Lao People’s Democratic Republic (Lao PDR), reports on disease frequency are very limited. This study aimed to report frequencies of the main cause of admission among inpatients of a tertiary general hospital (Mittaphab Hospital) in Vientiane. Subjects were inpatients who were admitted from January 3 to February 2 in 2017. The dataset were made as a pilot run to establish hospital statistics. The data on sex, age, address (province), dates of admission and discharge, and main diagnosis were collected from paper-based medical charts. International Classification of Diseases 10 was applied for classifying the main diagnosis. During the 1-month period, 1,201 inpatients (637 males and 564 females) were admitted, including 171 (14.2%) aged <20 years and 254 (21.1%) aged ≥60 years. About 20% patients were from outside of Vientiane. Among them, 67.5% (62.5% in males and 73.8% in females) were admitted within 7 days. The main causes with more than 10% in males were injury and poisoning S00-T98 (49.8%), while those in females were injury and poisoning S00-T98 (25.2%), pregnancy and childbirth O00-O99 (19.0%), and diseases of genitourinary system N00-N99 (13.7%). Injury and poisoning S00-T98 among inpatients aged <20 years was 81.8% in males and 59.0% in females. Among those aged 20–59 years, it was 49.9% and 22.4%, and among those aged ≥60 years it was 22.3% and 16.9%, respectively. This is the first report on the frequencies of main diseases among inpatients in Lao PDR. Injury was the first main cause of admission at the tertiary hospital.

Abstract Background Testing for HIV at birth has the potential to identify infants infected in utero, and allows for the possibility of beginning treatment immediately after birth; point of care (POC) testing allows rapid return of results and faster initiation on treatment for positive infants. Eswatini piloted birth testing in three public maternities for over 2 years. Methods In order to assess the acceptability of POC birth testing in the pilot sites in Eswatini, interviews were held with caregivers of HIV-exposed infants who were offered birth testing (N = 28), health care workers (N = 14), and policymakers (N = 10). Participants were purposively sampled. Interviews were held in English or SiSwati, and transcribed in English. Transcripts were coded by line, and content analysis and constant comparison were used to identify key themes for each respondent type. Results Responses were categorized into: knowledge, experience, opinions, barriers and challenges, facilitators, and suggestions to improve POC birth testing. Preliminary findings reveal that point of care birth testing has been very well received but challenges were raised. Most caregivers appreciated testing the newborns at birth and getting results quickly, since it reduced anxiety of waiting for several weeks. However, having a favorable experience with testing was linked to having supportive and informed family members and receiving a negative result. Caregivers did not fully understand the need for blood draws as opposed to tests with saliva, and expressed the fears of seeing their newborns in pain. They were specifically grateful for supportive nursing staff who respected their confidentiality. Health care workers expressed strong support for the program but commented on the high demand for testing, increased workload, difficulty with errors in the testing machine itself, and struggles to implement the program without sufficient staffing, especially on evenings and weekends when phlebotomists were not available. Policymakers noted that there have been challenges within the program of losing mothers to follow up after they leave hospital, and recommended stronger linkages to community groups. Conclusions There is strong support for scale-up of POC birth testing, but countries should consider ways to optimize staffing and manage demand.
