Published: April 2024

Background: Physiological 0.9% saline is commonly used as an irrigation fluid in modern arthroscopy. There is a growing body of evidence that a hyperosmolar saline solution has chondroprotective effects, especially if iatrogenic injury occurs. Purpose: To (1) corroborate the superiority of a hyperosmolar saline solution regarding chondrocyte survival after mechanical injury and (2) observe the modulatory response of articular cartilage to osmotic stress and injury. Study Design: Controlled laboratory study. Methods: Osteochondral explants were isolated from bovine stifle joints and exposed to either 0.9% saline (308 mOsm) or hyperosmolar saline (600 mOsm) and then damaged with a sharp dermatome blade to attain a confined full-thickness cartilage injury site, incubated in the same fluids for another 3 hours, and transferred to chondropermissive medium for further culture for 1 week. Chondrocyte survival was assessed by confocal imaging, while the cellular response was evaluated over 1 week by relative gene expression for apoptotic and inflammatory markers and mediator release into the medium. Results: The full-thickness cartilage cut resulted in a confined zone of cell death that mainly affected superficial zone chondrocytes. Injured samples that were exposed to hyperosmolar saline showed less expansion of cell death in both the axial ( P < .007) and the coronal ( P < .004) plane. There was no progression of cell death during the following week of culture. Histological assessment revealed an intact cartilage matrix and normal chondrocyte morphology. Inflammatory and proapoptotic genes were upregulated on the first days postexposure with a notable downregulation toward day 7. Mediator release into the medium was concentrated on day 3. Conclusion: This in vitro cartilage injury model provides further evidence for the chondroprotective effect of a hyperosmolar saline irrigation fluid, as well as novel data on the capability of articular cartilage to quickly regain joint homeostasis after osmotic stress and injury. Clinical Relevance: Raising the osmolarity of an irrigating solution may be a simple and safe strategy to protect articular cartilage during arthroscopic surgery.

Purpose This study evaluated the impact of obesity on cardiometabolic risk factors (CRF) interrelationships and predictive efficiency of CVD development in older African (AA) and European Americans (EA). Design A comparative research design evaluated CRF risk profile differences between participant groups. Setting Seven neighborhoods in a southern US city. Subjects A sample of 179 older AA (n = 128) and EA (n = 51) adults. Measures Non-fasting blood samples were evaluated for lipids and lipoproteins, glycosylated hemoglobin, systolic –(SBP) and diastolic blood pressure (DBP), body mass index (BMI), body fat percentage (BF%) and physical function. Analysis Data were analysis with descriptive statistics, t-tests, and correlations. Results AA were heavier than EA although all had above average age-appropriate fitness. Means and relationships between CRF and other variables were different ( P < .05) based on race. Both AA (41.3 + 5.8) and EA (38.6 + 6.4) BF% were CRF risks. Holding BMI constant, CRF were generally not related, and the relationships were different for AA and EA. AA had a range of 13.0 to 27.2% more favorable values for cholesterol, HDL-C, and triglyceride. EA had favorable A1c (EA 5.8 vs AA 6.2%) values. Conclusions A limitation of this report is the small sample size. Although further research is warranted, these findings suggest population specific CRF selections would improve CVD prediction in AA.

Published: April 2024

Context Incorporation of a palliative care approach is increasingly needed in primary care and nursing home care because most people with a life-limiting illness or frailty live there. Objectives To explore patients’ and relatives’ experiences of palliative care at home and in nursing homes. Methods Generic qualitative research in a purposive sample of patients with an estimated life expectancy of <1 year, receiving care at home or in a nursing home, and their relatives. Data is collected through semi-structured interviews and thematically analyzed by a multidisciplinary research team. Results Seven patients and five relatives participated. Three essential elements of palliative care and their contributing factors emerged: 1) be seen (personal attention, alignment to who the patient is as a person, and feeling connected) 2) information needs (illness trajectory and multidimensional symptoms and concerns, and 3) ensuring continuity (single point of contact, availability of HCPs, and coordination of care). Patients and relatives experienced loss of control and safety if these essentials were not met, which depended largely on the practices of the individual health care professional. Conclusion In both primary care and nursing home care, patients and relatives expressed the same essential elements of palliative care. They emphasized the importance of being recognized as a unique person beyond their patient status, receiving honest and clear information aligned with their preferences, and having care organized to ensure continuity. Adequate competence and skills are needed, together with a care organization that enables continuity to provide safe and person-centered care.
A seesaw of equilibrium, midwives’ experiences of infection prevention and control guideline adherence: A qualitative descriptive study
Authors: McCarthy Maura , Giltenane Martina , Doody Owen 
Published: April 2024

Background Infection prevention and control guidelines play a key role in preventing infections which can impact mothers and their newborn’s quality of life. Despite the presence of evidenced-based infection prevention and control guidelines, midwives’ adherence can be suboptimal internationally. The identification of facilitators and barriers to infection prevention and control guidelines can support practice and facilitate midwifery care. Aim To understand midwives’ experiences of the barriers and facilitators when adhering to infection prevention and control guidelines. Methods A qualitative descriptive study using semi-structured interviews with 10 midwives from February to March 2022. The interviews were audio recorded, transcribed verbatim, and analysed utilising Braun and Clarke’s thematic analysis framework involving the six steps of becoming familiar with the data, generating initial codes, generating themes, reviewing themes, defining and naming the themes, and presenting themes. Findings Two themes developed; seesaw for equilibrium and back to basics: learning on your feet. Midwives experienced conflicting emotional motivators in the need for professional integrity towards infection prevention and control guideline adherence. The work environment impacts on midwives’ ability to adhere to guidelines and communication and education have a vital role to play in infection prevention and control guideline adherence. Conclusions While midwives have a strong sense of protection of professional integrity, work conditions such as environment, organisational structures, and management systems affect midwives’ adherence to infection prevention and control guidelines. Effective education, training, and communication are required to promote infection prevention and control guideline adherence.

Published: April 2024

Background In 2020, as a result of evidence of demonstrated safety of an initial pilot program, our institution set out to implement a peripheral vasopressor infusion protocol. Objective To evaluate the use of peripheral lines for vasopressor administration to reduce placement of unnecessary central lines and central line days. Methods This is an Institutional Review Board approved, single center retrospective chart review conducted as pre/post-analysis. Our hospital is a quaternary care, level 1 trauma center in Hartford, Connecticut that serves 100,000-120,000 patients annually. Patients >18 years admitted to an intensive care unit (ICU) were included if meeting protocol specific inclusion criteria pertaining to moderate expected duration and dose of vasopressor. Patients were excluded if vasculature not supportive of placement of two peripheral intravenous (PIV) sites, PIV sites without brisk blood return, had a limb restriction, or metacarpal line. All analyses were conducted with SPSS v. 26 (IBM; Armonk, NY 2019), using an a priori alpha level of 0.05 such that all results yielding p < .05 were deemed statistically significant. Primary efficacy outcomes of this study are number of central lines placed and number of central line days. The primary safety outcome is the number of extravasation events attributed to peripheral administration of vasopressors. Results Overall, 146 patients avoided central line placement constituting a 58.4% ( p < .001) decrease in central line placement with peripheral vasopressor use. Out of 382 administrations there were a total of 14 extravasation events that occurred with peripheral vasopressor use in the post-intervention group. Implementation was associated with a statistically significant reduction in CLABSI occurrence. Conclusions The results of this analysis demonstrate that vasopressors can peripherally administered safely, when proximal to the antecubital fossa, at lower doses, and for short durations of infusion with minimal adverse events.

Background Assessing the use and effectiveness of complementary and integrative health (CIH) therapies via survey can be complicated given CIH therapies are used in various locations and formats, the dosing required to have an effect is unclear, the potential health and well-being outcomes are many, and describing CIH therapies can be challenging. Few surveys assessing CIH therapy use and effectiveness exist, and none sufficiently reflect these complexities. Objective In a large-scale Veterans Health Administration (VA) quality improvement effort, we developed the “Complementary and Integrative Health Therapy Patient Experience Survey”, a longitudinal, electronic patient self-administered survey to comprehensively assess CIH therapy use and outcomes. Methods We obtained guidance from the literature, subject matter experts, and Veteran patients who used CIH therapies in designing the survey. As a validity check, we completed cognitive testing and interviews with those patients. We conducted the survey (March 2021-April 2023), inviting 15,608 Veterans with chronic musculoskeletal pain with a recent CIH appointment or referral identified in VA electronic medical records (EMR) to participate. As a second validity check, we compared VA EMR data and patient self-reports of CIH therapy utilization a month after survey initiation and again at survey conclusion. Results The 64-item, electronic survey assesses CIH dosing (amount and timing), delivery format and location, provider location, and payor. It also assesses 7 patient-reported outcomes (pain, global mental health, global physical health, depression, quality of life, stress, and meaning/purpose in life), and 3 potential mediators (perceived health competency, healthcare engagement, and self-efficacy for managing diseases). The survey took 17 minutes on average to complete and had a baseline response rate of 45.3%. We found high degrees of concordance between self-reported and EMR data for all therapies except meditation. Conclusions Validly assessing patient-reported CIH therapy use and outcomes is complex, but possible.

Abstract
Background
Insecticide resistance (IR) is one of the major threats to malaria vector control programs in endemic countries. However, the mechanisms underlying IR are poorly understood. Thus, investigating gene expression patterns related to IR can offer important insights into the molecular basis of IR in mosquitoes. In this study, RNA-Seq was used to characterize gene expression in Anopheles gambiae surviving exposure to pyrethroids (deltamethrin, alphacypermethrin) and an organophosphate (pirimiphos-methyl).

Results
Larvae of An. gambiae s.s. collected from Bassila and Djougou in Benin were reared to adulthood and phenotyped for IR using a modified CDC intensity bottle bioassay. The results showed that mosquitoes from Djougou were more resistant to pyrethroids (5X deltamethrin: 51.7% mortality; 2X alphacypermethrin: 47.4%) than Bassila (1X deltamethrin: 70.7%; 1X alphacypermethrin: 77.7%), while the latter were more resistant to pirimiphos-methyl (1.5X: 48.3% in Bassila and 1X: 21.5% in Djougou). RNA-seq was then conducted on resistant mosquitoes, non-exposed mosquitoes from the same locations and the laboratory-susceptible An. gambiae s.s. Kisumu strain. The results showed overexpression of detoxification genes, including cytochrome P450s (CYP12F2, CYP12F3, CYP4H15, CYP4H17, CYP6Z3, CYP9K1, CYP4G16, and CYP4D17), carboxylesterase genes (COEJHE5E, COE22933) and glutathione S-transferases (GSTE2 and GSTMS3) in all three resistant mosquito groups analyzed. Genes encoding cuticular proteins (CPR130, CPR10, CPR15, CPR16, CPR127, CPAP3-C, CPAP3-B, and CPR76) were also overexpressed in all the resistant groups, indicating their potential role in cross resistance in An. gambiae. Salivary gland protein genes related to ‘salivary cysteine-rich peptide’ and ‘salivary secreted mucin 3’ were also over-expressed and shared across all resistant groups.

Conclusion
Our results suggest that in addition to metabolic enzymes, cuticular and salivary gland proteins could play an important role in cross-resistance to multiple classes of insecticides in Benin. These genes warrant further investigation to validate their functional role in An. gambiae resistance to insecticides.
Optimization of fermentation conditions and medium components for chrysomycin a production by Streptomyces sp. 891-B6

Published: April 2024

Abstract
Background
Chrysomycin A (CA) is a promising antibiotic for treatment of Gram-positive bacterial infections and cancers. In order to enhance CA yield, optimization of fermentation conditions and medium components was carried out on strain Streptomyces sp. 891-B6, an UV-induced mutant with improved CA titer compared with its wide-type marine strain 891.

Results
Using one-way experiment, the optimal fermentation conditions for CA production in 1-L shake flask were obtained as follows: 12 days of fermentation time, 5 days of seed age, 5% of inoculum volume ratio, 200 mL of loading volume and 6.5 of initial pH. By response surface methodology, the optimal medium components determined as glucose (39.283 g/L), corn starch (20.662 g/L), soybean meal (15.480 g/L) and CaCO3 (2.000 g/L).

Conclusion
Validation tests showed that the maximum yield of CA reached 1601.9 ± 56.7 mg/L, which was a 60% increase compared to the initial yield (952.3 ± 53.2 mg/L). These results provided an important basis for scale-up production of CA by strain 891-B6.
Comparative secretome analysis of Striga and Cuscuta species identifies candidate virulence factors for two evolutionarily independent parasitic plant lineages
Authors: Bradley James M. , Butlin Roger K. , Scholes Julie D. 
Published: April 2024

Abstract
Background
Many parasitic plants of the genera Striga and Cuscuta inflict huge agricultural damage worldwide. To form and maintain a connection with a host plant, parasitic plants deploy virulence factors (VFs) that interact with host biology. They possess a secretome that represents the complement of proteins secreted from cells and like other plant parasites such as fungi, bacteria or nematodes, some secreted proteins represent VFs crucial to successful host colonisation. Understanding the genome-wide complement of putative secreted proteins from parasitic plants, and their expression during host invasion, will advance understanding of virulence mechanisms used by parasitic plants to suppress/evade host immune responses and to establish and maintain a parasite-host interaction.

Results
We conducted a comparative analysis of the secretomes of root (Striga spp.) and shoot (Cuscuta spp.) parasitic plants, to enable prediction of candidate VFs. Using orthogroup clustering and protein domain analyses we identified gene families/functional annotations common to both Striga and Cuscuta species that were not present in their closest non-parasitic relatives (e.g. strictosidine synthase like enzymes), or specific to either the Striga or Cuscuta secretomes. For example, Striga secretomes were strongly associated with ‘PAR1’ protein domains. These were rare in the Cuscuta secretomes but an abundance of ‘GMC oxidoreductase’ domains were found, that were not present in the Striga secretomes. We then conducted transcriptional profiling of genes encoding putatively secreted proteins for the most agriculturally damaging root parasitic weed of cereals, S. hermonthica. A significant portion of the Striga-specific secretome set was differentially expressed during parasitism, which we probed further to identify genes following a ‘wave-like’ expression pattern peaking in the early penetration stage of infection. We identified 39 genes encoding putative VFs with functions such as cell wall modification, immune suppression, protease, kinase, or peroxidase activities, that are excellent candidates for future functional studies.

Conclusions
Our study represents a comprehensive secretome analysis among parasitic plants and revealed both similarities and differences in candidate VFs between Striga and Cuscuta species. This knowledge is crucial for the development of new management strategies and delaying the evolution of virulence in parasitic weeds.

Abstract
Background
There are only six past reports of super-refractory status epilepticus induced by spinal anesthesia. None of those patients have died. Only < 15 mg of bupivacaine was administered to all six of them and to our case. Pathophysiology ensuing such cases remains unclear.

Case presentation
A 27 year old gravida 2, para 1, mother at 37 weeks of gestation came to the operating theater for an elective cesarean section. She had no significant medical history other than controlled hypothyroidism and one episode of food allergy. Her current pregnancy was uneventful. Her American Society of Anesthesiologists (ASA) grade was 2. She underwent spinal anesthesia and adequate anesthesia was achieved. After 5–7 min she developed a progressive myoclonus. After delivery of a healthy baby, she developed generalized tonic clonic seizures that continued despite the induction of general anesthesia. She had rhabdomyolysis, one brief cardiac arrest and resuscitation, followed by stress cardiomyopathy and central hyperthermia. She died on day four. There were no significant macroscopic or histopathological changes in her brain that explain her super refractory status epilepticus. Heavy bupivacaine samples of the same batch used for this patient were analyzed by two specialized laboratories. National Medicines Quality Assurance Laboratory of Sri Lanka reported that samples failed to confirm United States Pharmacopeia (USP) dextrose specifications and passed other tests. Subsequently, Therapeutic Goods Administration of Australia reported that the drug passed all standard USP quality tests applied to it. Nonetheless, they have detected an unidentified impurity in the medicine.

Conclusions
After reviewing relevant literature, we believe that direct neurotoxicity by bupivacaine is the most probable cause of super-refractory status epilepticus. Super-refractory status epilepticus would have led to her other complications and death. We discuss probable patient factors that would have made her susceptible to neurotoxicity. The impurity in the drug detected by one laboratory also would have contributed to her status epilepticus. We propose several possible mechanisms that would have led to status epilepticus and her death. We discuss the factors that shall guide investigators on future such cases. We suggest ways to minimize similar future incidents. This is an idiosyncratic reaction as well.

IgG4-Related disease with diffuse myopericardial involvement- value of CMR: a case report and literature review of cardiac involvement
Authors: Houshmand Golnaz , Moosavi Najme-Sadat , Shahbazkhani Amirhossein , Pouraliakbar Hamidreza 
Published: April 2024

Abstract
Background
IgG4-related disease is a fibro-inflammatory disorder with an unknown etiology, which can affect multiple organ systems, including the cardiovascular system. While most reported cases of cardiovascular involvement are primarily associated with the aorta, there have been sporadic reports of isolated cardiac involvement.

Case presentation
This paper presents a documented case of IgG4-related systemic disease with symptoms indicative of restrictive cardiomyopathy. Subsequent Cardiac Magnetic Resonance imaging revealed diffuse myopericardial involvement, characterized by pericardial thickening and enhancement, accompanied by subepicardial and myocardial infiltration. Considering the rarity of cardiac involvement in our case, we conducted a thorough review of the existing literature pertaining to various patterns of cardiac involvement in IgG4-related disease, as well as the diagnostic modalities that can be employed for accurate identification and assessment.

Conclusions
This case report sheds light on the importance of recognizing and evaluating cardiac manifestations in IgG4-related systemic disease to facilitate timely diagnosis and appropriate management.
