ABSTRACT

BACKGROUND: Elderly patients with chronic diseases are very vulnerable during the transition from hospital to home and have a high need for transitional care. The quality of transitional care is closely related to patient health outcomes. Using appropriate scales to evaluate the quality of transitional care is important for efforts aimed at improving it. The study aimed to analyze the consistency between the Chinese version of the Partners at Care Transitions Measure (PACT-M) and the Care Transition Measure (CTM) in assessing the quality of transition care in elderly patients with chronic diseases. METHODS: This is a cross-sectional study, we used a convenience sampling method to investigate patients with chronic diseases aged ≧ 65 years who were about to be discharged from the three affiliated hospitals of Zhengzhou University in Henan Province, from August 2021 to May 2022. The sample consisted of 196 elderly patients with chronic diseases. Data were collected using a demographic survey, PACT-M, and CTM. We used EpiData 3.1 software for systematic logical error checking, SPSS 21.0 to analyze the data, and the Bland-Altman analysis to analyze the consistency of the two scales. RESULTS: The mean total scores for PACT-M and CTM were 65.52 ± 6.23 and 52.07 ± 7.26, respectively. The 95% confidence interval (CI) for the mean difference and ratios were (-31.52, 4.61) and (0.85, 1.72), with 3.57% and 5.10% of the points outside the 95% CI limits, separately. CONCLUSIONS: The difference analysis of Bland-Altman showed a good consistency of the two scales, while the rate analysis did not meet the a priori definition of good consistency, but it is very close to 5%. Therefore, the consistency of the two scales in assessing the quality of transitional care for elderly patients with chronic diseases needs to be further validated.

ABSTRACT

BACKGROUND: Post-traumatic hydrocephalus (PTH) is a complication of traumatic brain injury (TBI) that requires treatment and postoperative care. The shunt is one of the main treatments for PTH, which presents with dysfunction and infection. Considering brain injury, hydrocephalus shunt malfunction, and infection, family caregivers need to be responsible for caring for PTH patients, recognizing shunt malfunction and infection, and managing those patients accordingly from hospital to home. Understanding the experiences and needs of caregivers is beneficial for knowing their competency and quality of health care, ameliorating and ensuring future transition care. The study aimed to explore the feelings, experiences, and needs of family caregivers when caring for patients with TBI, PTH and shunts. METHODS: This was exploratory research of a purposive sample of 12 family caregivers of adult patients with TBI, PTH and shunts in five neurosurgery departments at a general hospital in Zhengzhou, Henan Province, China, using a semi-structured interview method. Data were collected from October 2021 to March 2022 before being analyzed by content analysis methods. RESULTS: Caregivers required professional and social knowledge and support in the areas of TBI, PTH and shunts, caregiving interventions, psychological care needs, and health insurance, just as caregivers do, but unlike other general caregivers, care for patients with TBI, PTH, and shunt is fraught with uncertainty and the need to manage shunt setting, and caregivers often experience 'complex emotional reaction' during the transitional period, where care needs and complex emotions may lead to a lack of caregiver confidence, which in turn may affect caregiving behaviors, and experiences that affect care may be mediated through caregiving confidence. The perceived availability of resources, particularly those that are still available to them when they return home, has a significant impact on participants' emotional response and sense of confidence. CONCLUSIONS: The emotional response and the impact of stressor caregivers after TBI, PTH, and shunt was important, and sometimes confidence in care appeared to be an intermediate and useful factor that needed to be considered as health professionals prepared to develop care resources on how to manage and empower patients with TBI, PTH, and shunt. Meanwhile, there may be gaps and inequities in supportive care for patients diagnosed with TBI, PTH, and shunt in China.

ABSTRACT

Allergic airway diseases, with incidence augmenting visibly as industrial development and environmental degradation, are characterized by sneezing, itching, wheezing, chest tightness, airway obstruction, and hyperresponsiveness. Current medical modalities attempt to combat these symptoms mostly by small molecule chemotherapeutants, such as corticosteroids, antihistamines, etc., via intranasal approach which is one of the most noninvasive, rapid-absorbed, and patient-friendly routes. Nevertheless, inherent defects for irritation to respiratory mucosa, drug inactivation and degradation, and rapid drug dispersal to off-target sites are inevitable. Lately, intratracheal micro/nano therapeutic systems are emerging as innovative alternatives for airway allergy interventions. This overview introduces several potential application directions of mic/nano-platform in the treatment of airway allergic diseases, including carriers, therapeutic agents, and immunomodulators. The improvement of the existing drug therapy of respiratory allergy management by micro/nano-platform is described in detail. The challenges of the micro/nano-platform nasal approach in the treatment of airway allergy are summarized and the development of micro/nano-platform is also prospected. Although still a burgeoning area, micro/nano therapeutic systems are gradually turning to be realistic orientations as crucial future alternative therapeutic options in allergic airway inflammation interventions.

ABSTRACT

BACKGROUND: The Partners at Care Transitions Measure (PACT-M) is a measure that assesses the quality and safety of care during the transition from hospital to home from the patient's perspective. The aim of this study was to examine the psychometric properties of the Chinese version of the PACT-M in Mainland China. METHODS: This was a cross-sectional study. A convenience sample of patients was recruited from three tertiary hospitals affiliated with Zhengzhou University, China. A total of 402 participants were interviewed before discharge, and 306 participants were interviewed one month after discharge from hospital to home using the Chinese version of the PACT-M. The statistical methods used in this study include the critical ratio value, item total correlation, test-retest, Cronbach's alpha, confirmatory factor analysis and exploratory factor analysis. RESULTS: The Chinese version of the PACT-M consists of PACT-M1 and PACT-M2, both of which have two dimensions, the number of items in both parts are consistent with the original English language version. The Cronbach's alpha values of the PACT-M1 and PACT-M2 were 0.802 and 0.741, and the test-retest reliability values were 0.885 and 0.837. The item content validity index and scale content validity index values of the PACT-M1 and PACT-M2 were all 1.0. CONCLUSION: The Chinese version of the PACT-M shows acceptable validity and reliability and can be used to assess the quality and safety of transitional care from hospital to home from the patient's perspective in mainland China.

ABSTRACT

Allergy, IgE-mediated inflammatory disorders including allergic rhinitis, asthma, and conjunctivitis, affects billions of people worldwide. Conventional means of allergy management include allergen avoidance, pharmacotherapy, and emerging therapies. Among them, chemotherapeutant intake via oral, intravenous, and intranasal routes is always the most common mean. Although current pharmacotherapy exhibit splendid anti-allergic effects, short in situ retention, low bioavailability, and systemic side effects are inevitable. Nowadays, nanoplatforms have provided alternative therapeutic options to obviate the existing weakness via enhancing the solubility of hydrophobic therapeutic agents, achieving in situ drug accumulation, exhibiting controlled and long-time drug release at lesion areas, and providing multi-functional therapeutic strategies. Herein, we highlight the clinical therapeutic strategies and deal with characteristics of the nanoplatform design in allergy interventions via intratracheal, gastrointestinal, intravenous, and ocular paths. The promising therapeutic utilization in a variety of allergic disorders is discussed, and recent perspectives on the feasible advances of nanoplatforms in allergy management are also exploited.

ABSTRACT

Liposomes (LPs), a delivery vehicle for stabilizing drugs, the characteristics of being easy to aggregate and fuse limit its application. Polymer coating is a promising way to tackle these issues. In this study, the potential of carboxymethyl chitosan (CMCS) and quaternary ammonium chitosan (TMC)-coated liposomes (CMCS/TMC-LPs) for improving the oral delivery capacity of curcumin (CUR) was explored. CMCS/TMC-LPs were prepared by electrostatic adsorption in a layer-by-layer manner. CMCS/TMC-LPs were spherical and had not obvious change in particle size and morphology after storage at 4 °C for 7 and 14 days. CMCS/TMC-LPs possessed favorable gastric acid tolerance (the cumulative drug release rate <10%) due to stable structure. The hemolysis test and Cell Counting Kit-8 (CCK8) assay appeared satisfactory biocompatibility of CMCS/TMC-LPs. The pharmacokinetics exhibited that oral absolute bioavailability of CUR loaded CMCS/TMC-LPs was about 38%, which was around 6 folds and 3 folds higher than CUR loaded LPs and CUR loaded TMC-LPs, respectively. The in vivo experiments showed that CMCS/TMC-LPs could prolong the retention time of CUR in systemic circulation and generate high level of CUR in liver, spleen and lung. Thus, CMCS/TMC-LPs may be a promising carrier for improving the efficacy and safety of orally administered drugs.

ABSTRACT

Opiates such as morphine exhibit analgesic effect in various pain models, but repeated and chronic morphine administration may develop resistance to antinociception. The purinergic signaling system is involved in the mechanisms of pain modulation and morphine tolerance. This study aimed to determine whether the P2X7 receptor in the ventrolateral midbrain periaqueductal gray (vlPAG) is involved in morphine tolerance. Development of tolerance to the antinociceptive effect of morphine was induced in normal adult male Sprague-Dawley (SD) rats through subcutaneous injection of morphine (10mg/kg). The analgesic effect of morphine (5mg/kg, i.p.) was assessed by measuring mechanical withdrawal thresholds (MWTs) in rats with an electronic von Frey anesthesiometer. The expression levels and distribution of the P2X7 receptor in the vlPAG was evaluated through Western blot analysis and immunohistochemistry. The acute effects of intra-vlPAG injection of the selective P2X7 receptor agonist Bz-ATP, the selective P2X7 receptor antagonist A-740003, or antisense oligodeoxynucleotide (AS ODN) targeting the P2X7 receptor on morphine-treated rats were also observed. Results demonstrated that repeated morphine administration decreased the mechanical pain thresholds. By contrast, the expression of the P2X7 receptor protein was up-regulated in the vlPAG in morphine tolerant rats. The percent changes in MWT were markedly but only transiently attenuated by intra-vlPAG injection of Bz-ATP (9nmol/0.3µL) but elevated by A-740003 at doses of 10 and 100nmol/0.3µL. AS ODN (15nmol/0.3µL) against the P2X7 receptor reduced the development of chronic morphine tolerance in rats. These results suggest that the development of antinociceptive tolerance to morphine is partially mediated by activating the vlPAG P2X7 receptors. The present data also suggest that the P2X7 receptors may be a therapeutic target for improving the analgesic effect of morphine in treatments of pain when morphine tolerance occurs.
