RESUMEN
The emergence of conjugated polymers (CPs) has provided a pathway to attain smart multifunctional conjugated polymer nanoparticles (CPNs) with enhanced properties and diverse applications. CPNs based on π-extended CPs exhibit high fluorescence brightness, low cytotoxicity, excellent photostability, reactive oxygen species (ROS) generation ability, high photothermal conversion efficiency (PCE), etc. which endorse them as an excellent theranostic tool. Furthermore, the unique light-harvesting and energy transfer properties of CPNs enables their transformation into smart functional nanohybrids with augmented performance. Owing to such numerous features, simple preparation method and an easy separation process, the CPNs and their hybrids have been constantly rising as a frontrunner in the domain of medicine and much work has been done in the respective research area. This review summarizes the recent progress that has been made in the field of CPNs for biological and biomedical applications with special emphasis on biosensing, imaging, and theranostics. Following an introduction into the field, a first large section provides overview of the conventional as well as recently established synthetic methods for various types of CPNs. Then, the CPNs-based fluorometric assays for biomolecules based on different detection strategies have been described. Later on, examples of CPNs-based probes for imaging, both in vitro and in vivo using cancer cells and animal models have been explored. The next section highlighted the vital theranostic applications of CPNs and corresponding nanohybrids, mainly via imaging-guided photodynamic therapy (PDT), photothermal therapy (PTT) and drug delivery. The last section summarizes the current challenges and gives an outlook on the potential future trends on CPNs as advanced healthcare material.

Globally, the treelines at higher elevations in mountains are reported to be advancing up-slope in response to recent climate warming. However, little is known about the treeline advancement in the Himalaya due to paucity of baseline vegetation data with which to compare, thus making their assessment and monitoring challenging. To fill this knowledge gap, the present study documented floristic and functional diversity of two treeline ecotone sites in Kashmir Himalaya. At each site, we conducted field sampling by laying five 20-m2 plots, with one at the highest limit (T0 plot), two plots below and two above the treeline and two nested subplots of 5-m2 for shrubs and five 1-m2 for herbs in each plot. We recorded 97 plant species belonging to 33 families from the two sites. We observed a considerable difference in species composition and distribution along the treeline ecotone. Majority of the species reported were perennial herbs. We observed a significant association of growth forms with the particular plots along the treeline ecotone. At both the sites, we recorded highest species richness at the T0 plot which was correlated well with the functional traits, thus indicating convergence of floristic and functional diversity at this transition zone. Interestingly, the T0 plot at both the sites showed maximum overlap of species with the plots above and below the treeline. In an era of climate warming, our study provides crucial baseline data that will facilitate assessment and monitoring of the Himalayan treelines.

Abstract: Cardiovascular diseases (CVDs) are leading causes of death in the world, owing to noticeable incidence and mortality. Traditional Chinese Medicine (TCM) SINI Decoction (SND) is used to prevent and treat CVDs, which has attracted extensive attention for its moderate and little side effects. However, the involved molecular mechanisms are exceedingly complicated and remain unclear. Systems pharmacology, as a novel approach that integrates systems biology and pharmacology plays a significant role in investigating the molecular mechanism of TCM. In systems pharmacology approach, we use to systematically uncover the mechanisms of action in Chinese medicinal formula SND as an effective treatment for CVDs, which mainly includes:1) molecular database building; 2) ADME evaluation; 3) target-fishing 4) network construction and analysis. The results show that 78 underlying valid ingredients and their corresponding 71 direct targets of SND were obtained. And SND take part in cardiomyocyte protection, blood pressure regulation, and lipid regulation module in treatment of CVDs by cooperative way. Systems pharmacology as an emerging field that investigates the molecular mechanisms of TCM through pharmacokinetic evaluation target prediction, and pathway analysis, which will facilitate the development of traditional Chinese herbs in modern medicine.

World Health Organization (WHO) recommends integration of mental health services into primary health services; however attitude of primary health care workers is one barrier to this. A cross sectional survey using the Community Attitudes towards Mental Illness (CAMI) was done. One hundred and twenty primary care workers were randomly selected from three local government areas. Descriptive and inferential statistics were used in analyses. The results showed that most primary health care workers hold a benevolent (mean = 2.47, SD = 0.52) attitude towards the mentally ill. Workers with 10 years or more experience tend to have less authoritarian (t = 3.19, p = 0.01) and less social restrictive (t = 3.90, p = 0.01) attitudes towards the mentally ill. There were no significant differences in attitude by gender, marital status, or designation of health care workers. The study showed that primary care workers have attitudes similar to that seen in the general population.

The IFNL4 gene is negatively associated with spontaneous and treatment-induced clearance of hepatitis C virus infection. The activity of IFNλ4 has an important causal role in the pathogenesis, but the molecular details are not fully understood. One possible reason for the detrimental effect of IFNλ4 could be a tissue-specific regulation of an unknown subset of genes. To address both tissue and subtype specificity in the interferon response, we treated primary human hepatocytes and airway epithelial cells with IFNα, IFNλ3 or IFNλ4 and assessed interferon mediated gene regulation using transcriptome sequencing. Our data show a surprisingly similar response to all three subtypes of interferon. We also addressed the tissue specificity of the response, and identified a subset of tissue-specific genes. However, the interferon response is robust in both tissues with the majority of the identified genes being regulated in hepatocytes as well as airway epithelial cells. Thus we provide an in-depth analysis of the liver interferon response seen over an array of interferon subtypes and compare it to the response in the lung epithelium.

AIM: Few studies have examined the relationship of individual periodontal parameters with individual systemic biomarkers. This study assessed the possible association between specific clinical parameters of periodontitis and systemic biomarkers of coronary heart disease risk in coronary heart disease patients with periodontitis. MATERIALS AND METHODS: Angiographically proven coronary heart disease patients with periodontitis (n = 317), aged >30 years and without other systemic illness were examined. Periodontal clinical parameters of bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) and systemic levels of high-sensitivity C-reactive protein (CRP), fibrinogen (FIB) and white blood cells (WBC) were noted and analyzed to identify associations through linear and stepwise multiple regression analyses. RESULTS: Unadjusted linear regression showed significant associations between periodontal and systemic parameters; the strongest association (r = 0.629; p < 0.001) was found between BOP and CRP levels, the periodontal and systemic inflammation marker, respectively. Stepwise regression analysis models revealed that BOP was a predictor of systemic CRP levels (p < 0.0001). BOP was the only periodontal parameter significantly associated with each systemic parameter (CRP, FIB, and WBC). CONCLUSION: In coronary heart disease patients with periodontitis, BOP is strongly associated with systemic CRP levels; this association possibly reflects the potential significance of the local periodontal inflammatory burden for systemic inflammation.

INTRODUCTION: Abdominal wall reconstruction (AWR) is an emerging subspecialty within general surgery. The practice of multidisciplinary team (MDT) meetings to aid decision making and improve patient care has been demonstrated, with widespread acceptance. This study presents our initial experience of over 150 cases of complex hernia patients discussed in a newly established MDT setting. METHODS: From February 2020 to July 2022 (30-month period), abdominal wall MDTs were held bimonthly. Key stakeholders included upper and lower gastrointestinal surgeons, a gastrointestinal specialist radiologist, a plastic surgeon, a high-risk anaesthetist and two junior doctors integrated into the AWR clinical team. Meetings were held online, where patient history, past medical and surgical history, hernia characteristics and up-to-date computed tomography scans were discussed. RESULTS: Some 156 patients were discussed over 18 meetings within the above period. Ninety-five (61%) patients were recommended for surgery, and 61 (39%) patients were recommended for conservative management or referred elsewhere. Seventy-eight (82%) patients were directly waitlisted, whereas seventeen (18%) required preoperative optimisation: three (18%) for smoking cessation, eleven (65%) for weight-loss management and three (18%) for specialist diabetic assessment and management. In total, 92 (59%) patients (including operative and nonoperative management) have been discharged to primary care. DISCUSSION: A multidisciplinary forum for complex abdominal wall patients is a safe process that facilitates decision making, promotes education and improves patient care. As the AWR subspecialty evolves, our view is that the "complex hernia MDT" will become commonplace. We present our experience and share advice for others planning to establish an AWR centre.

The precise and effective detection of neurotransmitters (NTs) is crucial for clinical investigation of neuronal processes, and timely monitoring of NT-related chronic diseases. However, sensitive detection of specific NT with unprecedented selectivity is highly challenging due to similarities in chemical and electronic structures of various interfering neurochemicals. Herein, an anionic conjugated polyelectrolyte Poly[(9,9-bis(4'-sulfonatobutyl)fluorene-co-alt-1,4-phenylene) sodium], PFPS was rationally designed and synthesized for amplified detection and point-of-care (PoC) determination of monoamine neurotransmitter, serotonin (5-Hydroxy tryptamine or 5-HT, also diagnostic biomarker of carcinoid tumor) in human blood plasma. The PFPS displayed a remarkable sensing response with an exceptionally high fluorescence quenching constant of 1.14×105â M-1 and an ultralow detection limit of 0.67â µM or 0.142â ppm, much below the clinical range. Furthermore, a smartphone-enabled portable platform was constructed for real-time onsite detection of 5-HT by quantification of visual fluorescence response of PFPS into RGB values using a color recognizer android application. The smartphone platform could be readily applied for convenient, non-invasive PoC testing of 5-HT levels in complex biological fluids accurately and is expected to revolutionize clinical diagnosis and personalized health care devices.
RESUMEN
The present study aimed to investigate the morphological features, phytochemicals, phenolic content, and antioxidant activity in different parts of Lagotis cashmeriana. The morphological features depicted that the plant is 7.9 ± 1.699 cm tall with flowers arranged into an inflorescence. The length of inflorescence was 2.597 ± 0.796 cm. Basal leaves were measuring 2.99 ± 0.58 cm. Besides, the number of basal leaves and inflorescence ranged from 4-9 and 0-4 respectively. Methanolic extract of leaves displayed the highest phenolic content (169.5 µg/mL of GAE), followed by inflorescences (157 µg/mL of GAE). Among aqueous extracts, leaves displayed the highest phenolic content (88.38 µg/mL of GAE), followed by inflorescences (76.95 µg/mL of GAE). The results of antioxidant study revealed that the methanolic extracts of leaves possessed the highest antioxidant potential (180.76 µg/mL of AAE). Interestingly, for each extract, there was a positive correlation between the phenolic content and the antioxidant activity.
RESUMEN
INTRODUCTION: Redeployment of orthopaedic consultants to a minor injuries unit (MIU) during the COVID-19 pandemic provided a unique opportunity to assess the impact of early senior specialist input on patient management. METHODS: Patient demographics, diagnosis, location of injury and disposal method were compared between three 7-day periods: during the April 2020 COVID-19 lockdown (period A), one month prior to period A (period B) and one year prior to period A (period C). Orthopaedic consultants staffed the MIU during period A, and emergency nurse practitioners staffed the MIU during periods B and C. RESULTS: Period A witnessed higher injury severity either due to modified activities or altered healthcare-seeking behaviour during lockdown. For fractures, compared with periods B and C, period A saw a lower rate of referral to fracture clinic (41% vs 100% vs 86%, p<0.001) and higher rate of discharge (38% vs 0% vs 9%, p<0.001). The median time to fracture clinic was also longer (15 days vs 6 days vs 10 days, p<0.001), indicating earlier institution of definitive care. There were no other significant differences between periods with radiology alerts and complaints received remaining largely unchanged. CONCLUSION: Early senior orthopaedic input in the patient journey from MIU had clear benefits, this being most true for fracture diagnoses. Earlier definitive management planning was observed as lower rates of fracture clinic referral, higher rates of discharge and deferred first fracture clinic reviews. This study highlights the benefits of greater partnership between MIU and orthopaedics. As the pandemic subsides and redeployed staff return to normal duties, a modification of this model could be utilised to ensure this partnership is sustainable.

BACKGROUND: Treatment for people with kidney disease is often associated with complicated combinations of medicines. Logistical challenges with traditiona paper-based prescribing means that these patients are particularly susceptible to medication-relation errors and harm. AIM: To improve the quality of care that people with kidney disease receive across Wales through a Value-Based digital transformation programme. SETTING: Renal units within the National Welsh Renal Clinical Network (WRCN). DEVELOPMENT: A novel Electronic Prescribing & Medicines Administration (EPMA) system, integrated into a patient care record and linked to a patient portal was developed in South West Wales (SWW) region of the WRCN, enabled by the Welsh Government (WG) Efficiency Through Technology Fund. National upscale was enabled through the WG Transformation Fund. IMPLEMENTATION: EPMA was designed and rolled out initially in SWW region of the WRCN (2018). A dedicated delivery team used the blueprint to finalise and implement a strategy for successful national roll-out eventually across all Wales (completed 2021). EVALUATION: A multi-factorial approach was employed, as both the technology itself and the healthcare system within which it would be introduced, were complex. Continuous cycles of action research involving informal and formal qualitative interviews with service-users ensured that EPMA was accessible and optimally engaging to all target stakeholders (patients and staff). Results confirmed that EPMA was successful in improving the quality of care that people with kidney disease receive across Wales, contributed to Value-Based outcomes, and put people who deliver and access care at the heart of transformation. CONCLUSION: Key findings of this study align directly with the national design principles to drive change and transformation, put forward by the WG in their plan for Health and Social Care: prevention and early intervention; safety; independence; voice; seamless care.

The structure and distribution patterns of Himalayan vegetation are poorly explored, and research on species composition along the elevation gradient in these mountain ranges is still deficient. The current study was undertaken to analyze the variation and pattern of plant species composition along a vertical gradient in northwestern Himalaya, India. A total of 18 sites were selected along an elevation gradient ranging from 2200 to 3900 m asl positioned at an interval of 100 m. The Renyi diversity profile, non-metric multidimensional scaling based on the Bray-Curtis dissimilarity metric and beta diversity components among the elevation belts were calculated. Furthermore, to study the influence of altitude on species richness and diversity, a generalized additive model was created. Two hundred and ten plant species representing 66 families and 147 genera were recorded. The Renyi diversity profiles show that the lower and mid-altitudes had rich species diversity. The results of the non-metric multidimensional scaling analysis show a considerable variation in the total plant species composition among the studied elevation belts. The observed multiple-site Sorensen dissimilarity index across the studied elevation belts was very high. The contribution of species replacement or the turnover component to the observed dissimilarity was much higher than the nestedness component. Furthermore, the herbaceous and tree richness showed a significant decrease with increase in elevation; however, the richness of shrubs showed a bimodal pattern. The present study increases our understanding of the trends and patterns of species richness along the vertical gradient in the Himalayan region.
RESUMEN
Strategic Environmental Assessment (SEA) is a proactive and collaborative method for environmental management designed to integrate environmental considerations into decision-making; and it is good for Sierra Leone. To understand whether SEA would be useful in the context of Sierra Leone, the authors interviewed 64 out of 78 experts face to face from March to July 2019. In addition, government policies and regulatory documents on environmental management and sustainable development, published articles served as secondary sources of data. Data were analyzed using descriptive statistics. These Sierra Leonean experts agreed that SEA would be useful for integration and achievement of improved sustainable urban planning strategies. However, the barriers identified to integrating SEA include: not addressing environmental issues during the preparation of policies and programs, insufficient political will, the absence of clear objectives, targets, principles and approaches, overlapping mandates among environmental institutions, and inadequate institutional coordination and non-integrated development framework as barriers to integrating SEA into their work. The study shows that SEA has the potential to have a positive impact on environmental concerns in decision-making, but it would need to be supported by stronger political will, legal frameworks, and improved technical guidance from the policy perspective. Moreover, we propose a conceptual framework for the inclusion of SEA into the urban planning process in Sierra Leone.

In an age of anthropocene, shifting plant phenology is one of the most striking biological indicators of global environmental change. Majority of the studies reporting shifts in plant phenology are available from the North America and Europe and largely scarce from the developing world, including the Himalaya; and studies integrating multiple methodological approaches to investigate the climate-driven phenological shifts are too rare. Here, we report the shifts in spring flowering phenology of model plant species, Sternbergia vernalis in response to the changing climate in Kashmir Himalaya, by integrating decadal field observational records with long-term herbarium and dated-photograph data, and supported with experimental evidences. Our results revealed a significant increasing trend of 0.038, 0.016 and 0.023 °C/year in the annual mean maximum temperature (Tmax), mean minimum temperature (Tmin) and diurnal temperature range (DTR) respectively; but an insignificant decreasing trend in annual precipitation of -1.24 mm/year over the last four decades (1980-2019) in this Himalayan region. The flowering phenology of S. vernalis has significantly advanced by 11.8 days/°C and 27.8 days/°C increase in Tmax and Tmin respectively, indicating that the climate warming has led to substantial shifts in flowering phenology of the model plant species. We also observed a strong association of seasonal Tmax (December-February) and DTR on the early onset of spring flowering, however precipitation had no significant effect on the timing of flowering. The greenhouse experiment results further supported a significant effect of temperature in triggering the phenological shifts, wherein the model plant grown under different temperature treatments flowered 9-20 days earlier compared to the control. Our study showcases the integrated use of multiple methodological approaches for unravelling the long-term phenological shifts in response to climate change, and contributes in filling the knowledge gaps in the phenological research from the developing world in general and the Himalaya in particular.

BACKGROUND: The link between measures of adiposity and prevalent screen-detected diabetes (SDM) in Africa has been less well investigated. We assessed and compared the strength of association and discriminatory capability of measures of adiposity including body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-hip-ratio (WHR) and waist-height-ratio (WHtR) for prevalent SDM risk in a sub-Saharan African population. METHODS: Participants were 8663 adults free of diagnosed type 2 diabetes, who took part in the nationally representative Cameroon Burden of Diabetes (CAMBoD) 2006 survey. Logistic regression models were used to compute the odd ratio (OR) and 95% confidence interval (95%CI) for a standard deviation (SD) higher level of BMI (7.3), WC (12.5), HC (11.7), WHR (0.19) and WHtR (0.08) with prevalent SDM risk. Assessment and comparison of discrimination used C-statistic and relative integrated discrimination improvement (RIDI, %). RESULTS: The adjusted OR and 95%CI for prevalent SDM with each SD higher adipometric variable were: 1.05 (0.98-1.13) for BMI, 1.30 (1.16-1.46) for WC, 1.18 (1.05-1.34) for HC, 1.05 (1.00-1.16) for WHR and 1.26 (1.11-1.39) for WHtR. C-statistic comparisons and RIDI analyses showed a trend toward a significant superiority of WC over other adipometric variables in multivariable models. Combining adiposity variables did not improve discrimination beyond multivariable models with WC alone. CONCLUSION: WC was the best predictors and to some extent WHtR of prevalent SDM in this population, while BMI and WHR were less effective.

A water-soluble cationic conjugated polyelectrolyte (CPE), poly(1,4-bis(6-(1-methylimidazolium)-hexyloxy)-benzene bromide) (PMI) displays extraordinary stability over the full pH range of 1-14 as well as in seawater, brine, urine, and other solutions and carries out efficient detection, discrimination, and removal of moderately dissimilar anionic surfactants (viz., sodium dodecyl benzenesulfonate (SDBS) and sodium dodecyl sulfate (SDS)) at very low levels (31.7 and 17.3 parts per billion (ppb), respectively). PMI formed stable hydrogels in the presence of SDS that remained unaffected by strong acids/bases, heating, ultrasonication, or exposure to light, whereas SDBS formed precipitate with PMI as a result of its different interpolymer cofacial arrangement via Columbic attraction. The complex-forming ability of PMI with SDS and SDBS facilitated their elimination from water or drug-doped urine samples without the use of any organic solvent, chromatographic technique, or solid support. This protocol, the first of its kind for the removal of anionic surfactants at very low concentrations from any type of solution and competitive environments, demonstrates an original application using a CPE. The surfactant-free sample solutions could be precisely analyzed for the presence of illicit drugs by any standard methods. Using PMI, a newly developed CPE, a rapid and practical method for the efficient detection, discrimination, and removal of SDS and SDBS at ppb levels from water and urine, under harsh conditions, and in natural chemical environments is demonstrated.

We evaluated perceptions and experiences of bearing sons and daughters among 42 women in Punjab, Pakistan, with special emphasis on son preference, changes in women's status within the marital family and resulting health effects. Data were collected through repeated, in-depth interviews in Urdu or Punjabi in an urban area in Lahore and a village 40 km. outside of Lahore. For triangulation purposes, four focus group discussions were performed with additional women, as well as in-depth interviews with eight mothers-in-law, three traditional practitioners and three medical practitioners. In general, these women felt that they had limited control over their lives, and this was exemplified by early marriages, high expectations on newly wed women to conceive and poor access to contraceptives. Women frequently expressed a strong preference for sons, mostly for economic reasons, reflecting women's subordinate position in society and the low economic value placed on women's work. Mothers of sons mainly discussed health problems during pregnancy and health effects of repeated childbearing. Mothers of daughters and women without children spoke of harassment in the family as well as in society. The results should be of importance in the public health planning in Pakistan as well as for those engaged in women's health issues internationally.

We studied women's beliefs and experiences of health and health care among 42 women in an urban slum area in Lahore and a village 40 km outside of Lahore. Data were collected through repeated, in-depth interviews in Urdu or Punjabi totalling 200 hours. For triangulation purposes, four focus group discussions with additional women were performed, as well as in-depth interviews with eight mothers-in-law, three traditional practitioners and three medical practitioners. The women's images of health reflected expectations on the women in society. Women from the village and women from the lowest socioeconomic stratum (SES) spoke of health in terms of physical strength; women from the city and women from low SES spoke of health in terms of mental strength; and women from medium SES discussed it in terms of cultural competence. Overall, health had a very low priority in these women's lives. Two health problems were reported by all women: mental tension leading to headache and white vaginal discharge leading to body pains and fatigue. These health problems were seen as part of womanhood; if treatment was sought, it was often from traditional healers. Village women had a flexible, pragmatic attitude toward health care resources and used all types until treated. Their relation to the doctor was specific; they were mostly concerned with the medical treatment. In contrast, city women chose health care providers depending on type of illness, and being met with respect was for them of equal concern. Childbearing experiences influenced the perceptions of health and health care. Mothers of daughters were seen to both need and deserve less food, health care and attention. These mothers were less vocal about health complaints. Women without children spoke of health in terms of physical strength. These women may have less access to health care because children cannot be used as an "excuse", and because they are not worth spending resources on.
