There is a clear clinical overlap between fibromyalgia, myalgic encephalomyelitis, and post-COVID 19 condition. Chronic fatigue, cognitive impairment, and widespread pain characterize these 3 syndromes. A steady line of investigation posits fibromyalgia as stress-evoked sympathetically maintained neuropathic pain syndrome and places dorsal root ganglia dysregulation with the ensuing small fiber neuropathy at the epicenter of fibromyalgia pathogenesis. This article discusses emerging evidence suggesting that similar mechanism may operate in post-COVID 19 condition.

The effects of inoculations with a N 2 -fixing cyanobacterium ( Anabaena cylindrica ) on nutrient and microbial dynamics of an arable Mollisol were studied under simulated high intensity rainfall. Inoculated and non-inoculated pots (controls) were incubated for 14 days and then subjected to three rain events in 1 week, followed by three weekly events for a total of six events. Soil samples at three depth layers (0–1, 5–6, and 10–11 cm) were taken at four time points: 1 day after inoculation, 14 days after inoculation, after rain 1, and after rain 6. Soil chlorophyll a (Chl a ), soluble fractions of N (SolN) and organic C (SolC), microbial biomass C (MBC) and N (MBN), microbial activity (FDA hydrolysis), and soil respiration (CO 2 efflux) were determined. Results revealed depth-related changes in Chl a , SolC, SolN, MBC, MBN, and FDA hydrolysis with greater effects at the surface layer (0–1 cm). Soil respiration varied with soil moisture and increased in inoculated treatments. After all rain simulations (49 days after inoculation), higher SolC, MBC, MBN, and FDA hydrolysis in surface soil of inoculated treatments indicated positive changes that persisted after consecutive rains. These findings suggest that cyanobacterial soil amendments might enhance soil quality and resiliency in agricultural soils exposed to high intensity rainfall.

Inflammation occurs in the initial stage of arterial atherosclerosis and serves as the first step in thrombus generation, with elevated inflammatory markers predicting myocardial infarction in coronary artery disease patients. Inflammation is known to alter the course of multiple diseases and can thus, also impact recovery post-treatment and surgical outcomes. Yet, there is a paucity of data regarding the relationship between inflammatory biomarkers and arterial thrombotic potential in peripheral artery disease (PAD) patients post-revascularization. Our pilot study attempts to fill this gap by evaluating if the expression of inflammatory biomarkers in PAD patients correlates with the incidence of thrombotic events post-revascularization. Plasma samples were prospectively collected from PAD patients who underwent revascularization from 2021 to 2023 at monthly time points for 6 months from the procedure. Patients were followed for a total of 6 months post-procedure and those who experienced thrombotic events were identified. Nine patients with thrombotic events and 16 with non-thrombotic events along with 5 healthy volunteers were analyzed. Plasma samples were analyzed for the following pro-inflammatory markers: IL-1β (Interleukin-1 beta), IL-6, and TNF- (Tumor Necrosis Factor - alpha), GM-CSF (Granulocyte-Macrophage Colony-Stimulating Factor), IFNγ (Interferon-gamma), IL-8, MCP-1 (Monocyte Chemoattractant Protein-1). The Kruskal-Wallis test was performed to compare bio-inflammatory marker levels between groups. A total of 303 patients were enrolled, of which 59 had thrombotic events. There were no differences between medications or disease burden between groups. Levels of circulating IL-6 and TNF- were significantly higher in the thrombosis cohort compared to the non-thrombosis cohort (55 vs. 38, < 0.02) and (159 vs. 110, < 0.02) respectively. Although there was a trend toward significance for IL-1β between the thrombotic cohort and non-thrombotic cohort, it did not reach statistical significance (18 vs. 11.5, = NS). There was no difference observed in aspirin's ability to dampen the inflammatory response between the two groups as all patients were on aspirin between the groups evaluated. Pro-inflammatory markers IL-6 and TNF- are significantly increased in patients, 1 month prior to an arterial thrombotic event, as compared to patients without thrombotic events. These biomarkers could predict impending thrombosis in patients with PAD post-revascularization.

Cyanobacteria are promising platforms for improving soil structure and fertility in the challenge of preserving and enhancing the soil resource and limiting environmental impacts of agriculture. To advance applications in agricultural settings, further understanding is needed on different soils and agroecological regions. This study aimed to evaluate the effects of inoculating an arable Mollisol from the U.S. Upper Midwest with the dinitrogen (N2)-fixing cyanobacterium Anabaena cylindrica. Three laboratory experiments were conducted to examine (1) soil structure and nutrient dynamics, (2) soil loss and soil and water nutrient levels after high intensity rain simulations, and (3) soil mineralization of cyanobacterial biomass. The first experiment showed that inoculation increased the water stability of macroaggregates (3–5 and 5–9 mm) after 6 weeks of incubation and increased soil soluble organic carbon (C), nitrogen (N), available phosphorus (P), and decreased C:N ratio. Rain simulations indicated that inoculation significantly decreased soil loss by runoff in one of eight rain events, with no other differences between treatments, although differences within treatments occurred with time. Soil inoculation led to increased soluble nutrient levels in runoff water, with highest nutrient mobilization in the first rain events. Finally, soil mineralization of cyanobacterial biomass indicated a gradual release of plant available N and P. These results confirm that soil cyanobacterial inoculations can increase aggregate stability, enhance resistance to water erosion and provide plant available nutrients, benefiting soil fertility. The study supports the advancement of cyanobacteria-based applications to reduce our reliance on chemical fertilizers and promote sustainability and resiliency in agriculture.

Plant–herbivore interactions are often mediated by plant microorganisms, and the “defensive mutualism” of epichloid fungal endophytes of grasses is an example. These endophytes synthesize bioactive alkaloids that generally have detrimental effects on the performance of insect herbivores, but the underlying mechanisms are not well understood. Our objective was to determine whether changes in the physiology and/or behavior of aphids explain the changes in performance of insects feeding on endophytic plants. We studied the interaction between the aphid Rhopalosiphum padi and the annual ryegrass Lolium multiflorum symbiotic (E+) or not symbiotic (E–) with the fungus Epichloë occultans that can synthesize loline alkaloids. We hypothesized that aphids feeding on E+ plants have higher energetic demands for detoxification of fungal alkaloids, thereby negatively impacting the individual performance, population growth, and structure. Aphids growing on E+ plants had lower values in morphometric and functional variables of individual performance, displayed lower birth rate, smaller population size, and dramatic structural changes. However, aphids exhibited lower values of standard metabolic rate (SMR) on E+ plants, which suggests no high costs of detoxification. Behavioral variables during the first 8 h of feeding showed that aphids did not change the phloem sap ingestion with the presence of fungal endophytes. We hypothesize that aphids may maintain phloem sap ingestion according to their fungal alkaloid tolerance capacity. In other words, when alkaloid concentrations overcome tolerance threshold, ingestion of phloem should decrease, which may explain the observed lower values of SMR in E+ feeding aphids.

Emotional disorders (ED) such as anxiety, depression and somatization are extremely prevalent disorders that can affect an individual’s quality of life and functionality. Primary Health Care (PHC) is the first place to identify most patients with these conditions. Mental health services in the Dominican Republic, as well as in Latin America and the Caribbean in general, are unable to provide appropriate care for most people with mental disorders. Using evidence-based treatment protocols is also crucial to make progress in helping people with ED. The PsicAP project is a group intervention that uses a transdiagnostic approach and is grounded in cognitive-behavioral techniques. The program is implemented in 7 group sessions, each lasting for one and a half hours. The program has been shown to be effective in reducing clinical symptoms, dysfunction, and in improving quality of life. It is also a non-time-intensive, low-cost treatment that is helpful for addressing EDs in a PHC context. The objective is to bring psychological treatments into PHC facilities of Dominican Republic, making them more accessible for a larger amount of the population.

Glutathione (GSH) plays an important role in protecting cells against oxidative damage. ABCC1 protein transports GSH. Although this protein is largely studied in cancer, due to multidrug resistance phenotype, its role in the tubular cells of the kidney is unknown. The goal of this study was to find out whether ABCC1 has a role in protecting cells from the distal nephron against the stress caused by high medullar osmolality. MA104 cells were treated with high concentrations of sodium chloride, urea, or both to raise the osmolality of the culture medium. Cell viability was accessed by MTT and trypan blue assays. ABCC1 expression and extrusion of carboxi-fluorescein (CF), a fluorescent ABCC1 substrate, were measured by flow cytometry. Incubation of MA104 cells in a high sodium concentration medium resulted in changes in cell granularity and altered expression and activity of ABCC1. Urea did not alter ABCC1 expression or activity, but reversed the observed NaCl effects. High sodium concentrations also had a negative effect on cell viability and urea also protected cells against this effect. Our findings demonstrate that ABCC1 plays a significant role in the protection of kidney epithelial cells against the stress caused by high sodium environment present in renal medulla.

Clinical Case A 67-year-old male presented to the Emergency Department with watery diarrhea of 2 days’ duration with intermittent rectal bleeding without fever, vomiting, or abdominal pain. Discussion The presence of heterotopic gastric mucosa in the colon is a rare finding of unclear pathogenesis probably related to a developmental error in gastric positioning and migration along the early embryonic life [1]. [...]gastric metaplasia is usually of pyloric type and arises in a chronic inflammatory background by reprogramming differentiation of reserve cells in the colonic crypts; therefore, the structure of normal gastric mucosa is not present [1, 2].

Background: Cancer patients frequently use complementary and alternative medicine (CAM), and spirituality has been associated with CAM use among patients. We evaluated how oncologists’ spirituality and religiosity are associated with personal use and patient recommendations for CAM. Methods: A survey was mailed to 1000 medical oncologists in the United States. The questionnaire asked about oncologists’ approaches to CAM use by patients, focusing on the use of herbs and supplement (HS), and about religiosity and spirituality. Results: Of 937 deliverable questionnaires, 392 were returned (response rate 42%). Respondents were mostly men (71%) and Caucasian (76%), with a median age of 48. Approximately 16% reported no religion, 19% Jewish, 24% Catholic, 28% Christian, and 13% other religions. Eighteen percent reported attending religious services at least once a week, including 15% who attend several times per week. Twenty-eight percent reported high theological pluralism (skepticism regarding whether one religion is comprehensively and uniquely true); 58% described themselves as moderately or very spiritual. Self-reported spirituality and religious service attendance were associated with using CAM personally and recommending HS to patients. In multivariate analyses, moderate-high spirituality and attending religious services less than monthly was positively associated with personal use of CAM: odds ratio (OR) = 3.10 (confidence interval [CI] = 1.5-6.5) and OR = 3.04 (CI = 1.5-6.6), respectively. Physicians with moderate to high spirituality were more likely to report recommending CAM in general (OR = 3.07, CI = 1.3-7.1), but less likely to report recommending HS (OR = 0.33, CI = 0.14-0.75). Conclusion: Self-reported spirituality is a significant factor among US oncologists’ decision to use CAM and recommend CAM to patients.

Myzus persicae Sulzer, like almost all aphids, associates with the endosymbiotic bacterium, Buchnera aphidicola. Although the accepted function of B. aphidicola is to complete the aphid diet with nutrients such as essential amino acids and vitamins, there is evidence that the bacteria may participate in the plant–insect interaction. Moreover, bacterial proteins with potential effector action on the metabolism of the host plant have been identified in the saliva of M. persicae. However, the possible involvement of B. aphidicola in relation to host plant acceptance by aphids needs further investigation. The aim of this study was to evaluate the effect that the disruption of the B. aphidicola–M. persicae symbiosis has on aphid feeding behaviour and on the expression of aphid salivary genes. The antibiotic rifampicin was administrated to adult aphids through artificial diets to disrupt the bacterial primary endosymbionts. Comparisons were made with control aphids, feeding from diet without rifampicin, as well as normal aphids fed on radish plants. Differences were found in the feeding behaviour of aposymbiotic aphids, which had delayed host acceptance and problems during stylet penetration into host plants. It was also found that B. aphidicola disruption down-regulated the expression of the Mp63 salivary protein gene. Together, these results indicate that B. aphidicola plays a role in plant–aphid interactions. The validity of the use of artificial diets in plant–aphid studies is also discussed.
