RESUMEN

Sleep is an important part of health, and when you go to sleep, how long you sleep, and how well you sleep all have a big impact on your health. Sleep may be required for regulating the body's metabolism, feelings, function, memory storage, brain recovery, and learning. Because of how important these processes are, sleep should be seen as just as important to health as what you eat and how much you exercise. Adults' sleep generally gets shorter and less restful, their sleep starts later and is more broken up, they have more sleep problems, and their rest-activity rhythms get weaker. In addition to receiving enough sleep (quality), healthy sleep habits also include maintaining a consistent sleep schedule. Ninety male college students with varying sleep schedules were analyzed for their physical and emotional well-being. By using factor analysis to categorize individuals' sleeping patterns across three dimensions regularity, quality, and quantity. We were able to develop sleep-habit measures. Clustering identified four distinct patterns of sleep behavior: good sleep was defined by regular, high-quality sleep despite being of comparatively brief duration; long sleep was predictable, fairly lengthy, but of minimal quality; short sleep was of excellent quality despite being short and irregular; and poor sleep was erratic, low-quality, and relatively long. The excellent sleepers also had reduced diastolic and systolic and a smaller means waist measurement. In addition, the poor sleepers had the lowest average MCS scores of all of the study groups. Poor sleepers also had the lowest mean scores on the Subjective Depression Scale (SDS). Issues involving glucose or lipid absorption were also more common in the short-term and long poor-sleep categories. Without restful sleep and a regular bedtime routine, it is impossible to maintain excellent mental and physical wellness, even if time and sleep are maintained constantly. Therefore, to produce suitable sleep recommendations for enhanced mental and physical health, we evaluated not only the quantity of sleep but also its consistency and high quality.

RESUMEN

Listeria Monocytogenes is transmitted via ingestion of contaminated food products and can cause invasive disease in susceptible hosts. Risk factors include immunocompromise; pregnancy; being elderly; and new-born. Listeriosis is uncommon but can occur in immunocompetent individuals and has a high mortality rate. We report a case of a 62-year-old female with no obvious risk factors who presented with atypical meningism. The patient was subsequently diagnosed with listeria meningitis and made a good recovery. The patient was a gardener regularly handling soil and ingested vegetables from her allotment patch; this case is reported to highlight less common risk factors and atypical ways in which listeria may present to the acute medical take.

RESUMEN

The term microbiome describes the assortment of microbes that dwell in and on a person's body, particularly in the gut, comprising fungi, bacteria, infectious agents and additional microbes. According to research, numerous elements of human well-being, such as digestion, immunological response and psychological well-being, have been linked to the microbiome. Preserving human wellness requires knowledge of the microbiome's stability and how it reacts to perturbations. According to preliminary research, adults' microbial ecosystems are considered stable with no signs of significant disturbances. This stability is not preserved by inertia and the system's interaction with restorative forces keeps the processes stable. Short antibiotic doses can result in quick and substantial microbiome alterations. However, there is confirmation that the taxonomic structure of the microbiome has at least recovered after such disruptions. The effect of antibiotics is individualized and can be altered by earlier exposure to a similar drug, which is a crucial aspect to remember. These results suggest that the individual's microbiome has adaptable qualities. Examining the microbiome's reactions to perturbations might be helpful in the prediction of potential instabilities and illness by revealing important features of function, microbial connections, and important species in the native microbiota. This information can benefit the management of the individual microbial community and the promotion of better health conditions.

RESUMEN

Infectious illnesses are predicted to experience a range of intricate responses from climate change, with some likely to rise, others to fall and many expected to undergo changes in prevalence. The study uses extensive data on global temperature variations and infectious illness transmission in people and animals. We now know a lot more about how the temperature changes across the world and whether or not the spread of infectious diseases impacts people as well as animals. Three primary topics of research are investigated in this paper: improving mechanical disease modelling, investigating the role of environmental variation in sickness dynamics, and understanding the consequences of temperature imbalances between parasites and hosts. By incorporating the latest data stemming from these advancements into weather-disease models and bridging critical knowledge gaps, enhancing our ability to forecast the probable effect of rising temperatures on the prevalence of diseases among both human and animal communities is possible. Through the establishment of important information gaps and the incorporation of new findings into models of climate-disease relationships, it will be possible to predict the effects of changes in climatic averages, variations and extremes on people and wildlife health.

RESUMEN

Drugs called glucocorticoids (GC) are often prescribed for both inpatient and outpatient settings. They are often used to treat a number of disorders due to their anti-inflammatory activity. Long-term use of GCs, especially long-term high-dose administrations, may result in a variety of negative effects. In Hilla City, Babylon Governorate of Iraq, Merjan Teaching Hospital, Al-Hilla Teaching Hospital's Joint Enology Clinic, and Al-Imam Al-Sadiq Hospital, were the sites of this case-control research, which was carried out. There were 100 total participants in this trial, of whom 50 were patients with osteoporosis (OP). The ages of the patients and the control collection were. They were chosen since their gender and ages matched. The findings show extensively senior level of parathyroid hormone (PTH) in OP patients when compared to the control group, whereas calcium (Ca) level into the patient group significantly lowered during association toward the manage set. In summary, there is a positive correlation between PTH and the condition of bone mineralization. In those who use GCs for a long time, PTH may be used as a prognostic marker to predict when bone mineral abnormalities would develop.

RESUMEN

Both perineural and intravenous dexamethasone and dexmedetomidine are used as local anaesthetic adjuncts to enhance peripheral nerve block characteristics. However, the effects of dexamethasone and dexmedetomidine based on their administration routes have not been directly compared, and the relative extent to which each adjunct prolongs sensory blockade remains unclear. This network meta-analysis sought to compare and rank the effects of perineural and intravenous dexamethasone and dexmedetomidine as supraclavicular block adjuncts. We sought randomised trials investigating the effects of adding perineural and intravenous dexamethasone or dexmedetomidine to long-acting local anaesthetics on supraclavicular block characteristics, including time to block onset and durations of sensory, motor and analgesic blockade. Data were compared and ranked according to relative effectiveness for each outcome. Our primary outcome was sensory block duration, with a 2-h difference considered clinically important. We performed a frequentist analysis, using the GRADE framework to appraise evidence. One-hundred trials (5728 patients) were included. Expressed as mean (95%CI), the control group (local anaesthetic alone) had a duration of sensory block of 401 (366-435) min, motor block duration of 369 (330-408) min and analgesic duration of 435 (386-483) min. Compared with control, sensory block was prolonged most by intravenous dexamethasone [mean difference (95%CI) 477 (160-795) min], followed by perineural dexamethasone [411 (343-480) min] and perineural dexmedetomidine [284 (235-333) min]. Motor block was prolonged most by perineural dexamethasone [mean difference (95%CI) 294 (236-352) min], followed by intravenous dexamethasone [289 (129-448)min] and perineural dexmedetomidine [258 (212-304)min]. Analgesic duration was prolonged most by perineural dexamethasone [mean difference (95%CI) 518 (448-589) min], followed by intravenous dexamethasone [478 (277-679) min] and perineural dexmedetomidine [318 (266-371) min]. Intravenous dexmedetomidine did not prolong sensory, motor or analgesic block durations. No major network inconsistencies were found. The quality of evidence for intravenous dexamethasone, perineural dexamethasone and perineural dexmedetomidine for prolongation of supraclavicular sensory block duration was 'low', 'very low' and 'low', respectively. Regardless of route, dexamethasone as an adjunct prolonged the durations of sensory and analgesic blockade to a greater extent than dexmedetomidine. Differences in block characteristics between perineural and intravenous dexamethasone were not clinically important. Intravenous dexmedetomidine did not affect block characteristics.

RESUMEN

AIM: To examine the performance of "appropriate" versus "inappropriate" computed tomography (CT) and to examine whether physicians who practise in a rural hospital in NSW Australia, achieved imaging appropriateness in their ordering of diagnostic CT examinations. MATERIALS AND METHODS: An audit of the electronic medical records of medical ward inpatients (during the 2016/2017 financial year) was carried out. De-identified data were extracted for all patients who had undergone diagnostic CT while on admission. Using the SPSS analytical software, chi-square tests for independence were conducted to check for difference between appropriate and inappropriate CT imaging. RESULTS: Of all the CT procedures, 92% were found to be appropriate. Appropriate CT confirmed the provisional diagnosis in more instances than inappropriate CT (132 versus three). This observed difference was significant with a small size effect (chi-squared [1, n=362]=8.58, p=0.003, φ=0.16). Similarly, appropriate CT significantly facilitated a change in the proposed direction of care (140 versus 40) (chi-squared [1, n=362]=7.75, p=0.005, φ=0.16). In addition, appropriate CT which confirmed diagnosis, resulted in a change in the proposed direction of care as opposed to inappropriate CT (115 versus one; chi-squared [1, n=362]=8.11, p=0.004, Cramer's V=0.24). CONCLUSION: Specialist physicians who practise in a rural hospital setting achieved CT appropriateness. Appropriate CT is beneficial to patient care. Adhering to recommended imaging guidelines is essential for achieving imaging appropriateness.

RESUMEN

OBJECTIVES: Historically, arthroplasty in systemic lupus erythematosus (SLE) patients has been less successful than for patients with osteoarthritis (OA). It is not known if SLE remains an independent risk factor for poor arthroplasty outcomes or if other factors, such as avascular necrosis (AVN), continue to play a role. METHODS: A case-control study using data from a single-institution arthroplasty registry compared SLE total hip arthroplasty (THA) and total knee arthroplasty (TKA) with OA controls matched by age, gender and presence of AVN. Baseline, two-year administrative and self-report data, and diagnosis leading to arthroplasty were evaluated. RESULTS: A total of 54 primary SLE THA and 45 primary SLE TKA were identified from May 2007 through June 2011. AVN was present in 32% of SLE THA and no TKA. SLE THA had worse preoperative WOMAC pain (42.5 vs. 52.7; p = 0.01) and function (38.8 vs. 48.0; p = 0.05) compared with OA. However, at two years there was no difference in WOMAC pain (91.1 vs. 92.1; p = 0.77) or WOMAC function (86.4 vs. 90.8; p = 0.28). SLE TKA were similar to OA in both preoperative pain (42.6 vs. 48.4; p = 0.14) and function (42.1 vs. 46.8; p = 0.30) and two-year pain (85.7 vs. 88.6; p = 0.50) and function (83.7 vs. 85.1; p = 0.23). Compared to OA, SLE THA and TKA patients had more renal failure (14% vs. 1%; p = 0.007) and hypertension (52% vs. 29%; p = 0.009). In a multivariate linear regression, SLE was not predictive of either poor pain or poor function. CONCLUSIONS: While SLE patients have more comorbidities than OA, and SLE THA have worse preoperative pain and function compared with OA controls, SLE was not an independent risk factor for poor short-term pain or function after either hip or knee arthroplasty.

RESUMEN

Irisin, a newly discovered, PGC-1α dependent myokine, has recently been shown to increase in circulation in response to sprint exercise. This study examined the effect of prolonged exercise on irisin concentrations in young men (n=7) as well as in young women (n=5) during different stages of the menstrual cycle. Seven young men completed 90 min of treadmill exercise at 60% of VO2max and a resting control trial. Five women completed the same exercise protocol in two different trials: during the early follicular phase and mid-luteal phase of the menstrual cycle. Blood samples were collected and analyzed for irisin concentrations immediately before exercise, at 54 and 90 min of exercise, and at 20 min of recovery (R20). Findings revealed that by 54 min of a 90 min treadmill exercise protocol at 60% of VO2max, irisin concentrations significantly increased 20.4% in young men and 20.3% as well as 24.6% in young women during the early follicular and mid-luteal phases of the menstrual cycle, respectively. However, by 90 min of exercise as well as R20, irisin concentrations were no longer elevated. Stage of the menstrual cycle did not affect responses in young women. Findings indicate that prolonged aerobic exercise produces a transient increase in irisin concentrations during the first hour of exercise for both genders and suggest that this form of moderate exercise may be helpful in improving fat metabolism.

RESUMEN

Introduction: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term. Materials and methods: This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray's test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up. Results: The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups. Conclusion: AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair.

RESUMEN

We explored pancreatic neuroendocrine tumors (PanNETs) associated with tuberous sclerosis complex (TSC) to determine their incidence in the TSC population; define their clinical, radiological, and pathological characteristics; and investigate their association with underlying genotypes. Retrospectively reviewed abdominal imaging of 219 patients with TSC, evaluating the incidence, size, and architecture of pancreatic lesions. Pathology records at Massachusetts General Hospital (MGH) were reviewed for all PanNET diagnoses in patients with TSC. Literature was reviewed for TSC-related PanNET cases. Nine patients with TSC were found to have a pancreatic lesion(s) on abdominal imaging and six patients have been diagnosed with a PanNET by pathology at MGH. Twelve cases of TSC-associated PanNETs have been reported in the literature. Of these 18 PanNET cases, one third were cystic, and the average age at resection was 26 years. Germline TSC2 mutations were found in all patients for whom genetic data were available (n = 3). We did not identify pancreatic angiomyolipomas in this series. Our results suggest that PanNETs are the most common pancreatic lesion in patients with TSC. Focal pancreatic mass lesions, solid or cystic, in patients with TSC should be considered possible PanNETs, and resection of the lesion may be clinically indicated.

RESUMEN

Pheochromocytomas and paragangliomas are rare neuroendocrine catecholamine producing tumors with varied clinical presentations, biochemistries and genetic makeup. These features outline the complexity and the difficulties in studying and understanding the oncogenesis of these tumors. The study of families with genetically inherited mutations in pheochromocytoma susceptibility genes has greatly enhanced our understanding of the pathophysiology and mechanisms of oncogenesis of the disease, and consequently changed our clinical approach. Several molecular pathways and mutations in their important regulatory proteins have been identified. Such mutations are responsible for the dysregulation of metabolic pathways involved in oxygen and nutrient sensing, apoptosis regulation, cell proliferation, migration and invasion. The knowledge derived from the study of these pathways will be fundamental in the future clinical management of these patients. As a rare disease that often masks its clinical presentation, the diagnosis is frequently missed and a high level of suspicion is required. Management of this disease requires a multidisciplinary team approach and will be discussed along with advances in its treatment.

RESUMEN

The response surface method was applied in this study to improve cellulase production from oil palm empty fruit bunch (OPEFB) by Botryosphaeria rhodina. An experimental design based on a two-level factorial was employed to screen the significant environmental factors for cellulase production. The locally isolated fungus Botryosphaeria rhodina was cultivated on OPEFB under solid-state fermentation (SSF). From the analysis of variance (ANOVA), the initial moisture content, amount of substrate, and initial pH of nutrient supplied in the SSF system significantly influenced cellulase production. Then the optimization of the variables was done using the response surface method according to central composite design (CCD). Botryosphaeria rhodina exhibited its best performance with a high predicted value of FPase enzyme production (17.95 U/g) when the initial moisture content was at 24.32%, initial pH of nutrient was 5.96, and 3.98 g of substrate was present. The statistical optimization from actual experiment resulted in a significant increment of FPase production from 3.26 to 17.91 U/g (5.49-fold). High cellulase production at low moisture content is a very rare condition for fungi cultured in solid-state fermentation.

RESUMEN

OBJECTIVES: Management of labor analgesia and post-cesarean delivery pain is challenging in the patient taking buprenorphine as opioid addiction maintenance therapy. We observed whether substituting clonidine for fentanyl in an epidural solution would provide adequate analgesia for labor and after cesarean delivery. METHODS: We substituted our standard 2 µg/mL fentanyl in 0.0625% bupivacaine epidural solution with 2 µg/mL clonidine in 0.0625% bupivacaine, or 1.2 µg/mL clonidine in 0.1% bupivacaine, for labor and post-cesarean analgesia in parturients on buprenorphine therapy. All cesarean deliveries were performed with a combined spinal-epidural technique and the catheters maintained for immediate postoperative analgesia using an epidural infusion. Catheters were discontinued the next day and patients were then managed with other analgesics based on obstetric preference. We recorded pain scores during labor and in the immediate post-surgical period; and supplemental medications given after epidural catheter removal. RESULTS: Fourteen patients were included in the study, of whom seven presented in spontaneous labor and seven had elective cesarean delivery. All laboring patients achieved good analgesia, and five of seven avoided supplemental opioid use in the postpartum phase. Of the postsurgical patients, six of seven had pain scores less than 5/10 at epidural catheter removal and three of seven avoided supplemental opioids postoperatively. CONCLUSIONS: The combination of clonidine and bupivacaine appears effective in parturients on buprenorphine therapy for opioid addiction maintenance. As study numbers were small and several factors were not examined, further confirmatory research is needed, including to determine the ideal dose of epidural clonidine in this setting.

RESUMEN

Diagnostic ultrasound has been clinically used for decades. More recently, high intensity focused ultrasound (HIFU) has been developed for therapeutic use as a non-invasive technique for tissue ablation. HIFU is also being investigated for advanced applications at the cellular level. Under guidance by magnetic resonance or ultrasound imaging, HIFU can achieve precise biological effects in tissue with a high safety profile. In this article, we discuss the basic principles, advantages and limitations of HIFU. We will also address the food and drug administration (FDA) approved clinical applications in the United States and highlight active HIFU research with promising clinical outcomes.

RESUMEN

To investigate the relationship between adrenal cell function and gap junction expression, a bovine adrenal cell line (SBAC) was studied. Western blot and immunocytochemical techniques were used to demonstrate gap junction expression in SBAC cell populations. Cells expressed alpha1 (connexin 43) gap junction protein at points of cell-to-cell contact. Gap junction number and size increased in populations treated with ACTH (40 mU/ml) or dibutyryl cAMP (DbcAMP, 1.0 mM). Treatment with either ACTH or DbcAMP increased steroid production and cAMP levels. SBAC cell number, however, decreased in ACTH- or DbcAMP-treated populations. The number of cells increased in cultures transfected with alpha1-antisense complementary DNA. Neither ACTH nor DbcAMP treatment decreased cell number or increased steroidogenesis in alpha1-antisense complementary DNA-transfected cell populations. However, cell populations in which gap junctions were inhibited retained the capacity to increase cAMP production in response to ACTH (40 mU/ml) treatment. Hormone-stimulated gapjunction expression and cell communication may represent an important factor in adrenal gland function and control of proliferation.

RESUMEN

Azole phenoxy hydroxyureas are a new class of 5-lipoxygenase (5-LO) inhibitors. Structure-activity relationship studies have demonstrated that electronegative substituents on the 2-phenyl portion of the oxazole tail increased the ex vivo potency of these inhibitors. Similar substitutions on the thiazole analogs had only minor contribution to the ex vivo activity. The trifluoromethyl-substituted oxazole 24 was the best compound of the oxazole series in both the ex vivo (6 h pretreated rats) and in vivo (3 h pretreated rats) RPAR assay with ED50 values of approximately 1 and 3.6 mg/kg, respectively, but was weakly active in the allergic guinea pig assay. Oxazole 50 was equally active in both the RPAR and guinea pig in vivo models and was similar to zileuton. The unsubstituted thiazole 52 was the best compound of the thiazole series, by inhibiting the leukotriene B4 biosynthesis in the RPAR assay (3 h pretreated rats) by 99%, at an oral dose of 10 mg/kg, and the bronchoconstriction in the allergic guinea pig by 50%, at an intravenous dose of 10 mg/kg. Oxazole 24 demonstrated high and selective 5-LO inhibitory activity in the in vitro assays, with IC50 values ranging from 0.08 microM in mouse macrophages to 0.8 microM in human peripheral monocytes to 1.2 microM in human whole blood. This activity was selective for 5-LO, as concentrations up to 15 microM in mouse macrophages did not affect prostaglandin formation. Oxazole 59 was the most active inhibitor in the human monocyte assay with an IC50 value of 7 nM.

RESUMEN

The syntheses of analogues of pemedolac (cis-1-ethyl-1,3,4,9-tetrahydro-4-(phenylmethyl)pyrano[3,4-b]indol e-1-acetic acid), a potent analgesic, are described. They were tested for analgesic and antiinflammatory effects in vivo and for inhibition of prostaglandin production in vitro. Analysis of structure-activity relationships shows that analgesic activity in this series is associated with 1S-cis stereochemistry, the presence of a pi-system (allyl or benzyl) at position 4, and a log P value greater than 4.0.

RESUMEN

The syntheses of five metabolites of the antiinflammatory drug etodolac (1,8-diethyl-1,3,4,9-tetrahydropyrano-[3,4-b]indole-1-acetic acid) are described, viz. 6-hydroxyetodolac, N-methyletodolac, 4-ureidoetodolac, 8-(1'-hydroxy)etodolac, and 4-oxoetodolac. These syntheses were used to confirm the identities of the metabolites. The metabolites themselves, as well as the previously reported metabolite 7-hydroxyetodolac, were tested in a rat adjuvant edema model and in vitro for their capacity to block prostaglandin production in chondrocyte cells. All either were inactive or possessed only marginal activity. The isolation of N-methyletodolac and 4-oxoetodolac from human and rat urine, respectively, is also described.
