Antiparasitic Agents

Background: COVID-19 has emerged as a pandemic that spread throughout the world in less than 6 months, leaving hundred thousand deaths behind. Surprisingly, old drug arsenal has now been applied as an option of treatment. Objective: The aim of this article was to accomplish a literature review concerning the antiparasitic chloroquine, ivermectin, nitazoxanide; as well as glucocorticoids as possible therapeutic agents to be applied in patients with COVID-19 in Brazilian hospitals. Methodology: clinical evidence of COVID-infected patients and literature consultation have been used for the construction of this article. On line searches and gray literature have also been consulted, whose database include PUBMED Central, BVS/BIREME, Web of Science, Science Direct, Higher Level Personnel Improvement Coordinator (CAPES), Periodic Door (Portal de Periódicos da CAPES, The Cochrane Library and PROSPERO). Results: chloroquine, ivermectin and nitazoxanide present antiviral characteristics to support their usage in phase 1 of COVID-19 symptoms. Glucocorticoids such as methylprednisolone and dexamethasone seem to be more efficient in patients with pulmonary symptoms such as those in phase 2B and 3. Conclusion: According to the articles raised in this review, antiparasitic agents are promising for patients with COVID-19 in the very beginning of the symptoms. Methylprednisolone and dexamethasone are best indicated for hospitalized patients with pulmonary commitment.

Background: COVID-19 has emerged worldwide in less than 6 months, leaving millions of deaths behind. While scientist search for new drugs, an old arsenal has been proposed as a form of treatment. Objective: This article was designed as a literature review, scrutinizing antiparasitic chloroquine, ivermectin, nitazoxanide; and also glucocorticoids, as candidates to be applied in patients with COVID-19 in some Brazilian hospitals. Methodology: clinical evidence of COVID-infected patients and literature consultation have been accomplished for the construction of this article. On line searches and gray literature have also been consulted, whose database include PUBMED Central, BVS/BIREME, Web of Science, Science Direct, Higher Level Personnel Improvement Coordinator (CAPES), Periodic Door (Portal de Periódicos da CAPES, The Cochrane Library and PROSPERO). Results: chloroquine, ivermectin and nitazoxanide do present antiviral characteristics to support their usage in phase 1 of COVID-19 symptoms. Glucocorticoids, especially methylprednisolone and dexamethasone, seem to be efficient in patients with pulmonary symptoms, such as those present in phase 2B and 3 of the disease. Conclusion: After analyzing the literature, antiparasitic agents constitute a promising approach for patients with COVID-19. However, their usage seems to be efficient in the very beginning of the symptoms. Methylprednisolone and dexamethasone are best indicated for hospitalized patients with pulmonary commitment.

Aim: to research through literature review, the mechanisms involved in the establishment of root resorptions. Mediators such as interleukins, prostaglandins, nitric oxide and systemic calcium available were studied in this review. Methods: On line searches were accomplished by scrutinizing the database available from PUBMED Central, BVS/BIREME. Web of Science, Science Direct, Periodic Portal from CAPES, as well as The Cochrane Library and PROSPERO were also used. The inclusion criteria were articles that described osteoclastic activity involving the hard dental tissues (cement, dentin and enamel). The search acquired 35 articles and excluded other 30. The articles acquired ranged from 1976 up to 2017. Results: the results showed that the combination of the immunologic mediators researched above will be the determinant factors on the establishment of root resorptions. Conclusions: Prostaglandins, Interleukins as well as the systemic calcium available are some of the most important factors for the establishment of root resorptions. Their final outcome, however, depends directly on the quality of injury inflicted over the group of teeth, or single tooth, involved.

Aim: this article describes the use of chloroquine as an antimalarial agent with potential antivirotic indications for COVID-19 infections. Methods: On line searches and gray literature have been used in the construction of this articles, whose database include PUBMED Central, BVS/BIREME, Web of Science, Science Direct, Higher Level Personnel Improvement Coordinator (CAPES), Periodic Door (Portal de Periódicos da CAPES, The Cochrane Library and PROSPERO). Results: chloroquine and hydroxychloroquine has shown appropriate clinical reports when associated with the antibiotic Azithromycin. It has been authorized for the clinical treatment of grave acute forms of COVID infections by countries like Brazil and USA. Conclusions: Chloroquine seems to have potential antivirotic properties that may be useful in the treatment of the grave acute forms of COVID-19 associated with Azithromycin. Nevertheless, Its indication must include ECG monitoring due to the risk of cardiac QT prolongation able to cause sudden deaths.

: In recent years, there has been an increasing interest in understanding the mysterious functions of nitric oxide (NO) and how this pleiotropic signaling molecule contributes to tumorigenesis. This review attempts to expose and discuss the information available on the immunomodulatory role of NO in cancer and recent approaches to the role of NO donors in the area of immunotherapy. To address the goal, the following databases were searched to identify relevant literature concerning empirical evidence: The Cochrane Library, Pubmed, Medline, EMBASE from 1980 through March 2020. Valuable attempts have been made to develop distinctive NO-based cancer therapy. Although the data do not allow generalization, the evidence seems to indicate that low / moderate levels may favor tumorigenesis while higher levels would exert anti-tumor effects. In this sense, the use of NO donors could have an important therapeutic potential within immunotherapy, although there are still no clinical trials. The emerging understanding of NO-regulated immune responses in cancer may help unravel the recent features of this “double-edged sword” in cancer physiological and pathologic processes and its potential use as a therapeutic agent for cancer treatment. In short, in this review, we discuss the complex cellular mechanism in which NO, as a pleiotropic signaling molecule, participates in cancer pathophysiology. We also debate the dual role of NO in cancer and tumor progression, and clinical approaches for inducible nitric oxide synthase (iNOS) based therapy against cancer.

Abstract Background Treatments for joint pain and dysfunction focus on restoration of joint motion, improvement in pain and a return to the previous level of the patient's daily activity. Therapeutic ultrasound is a noninvasive modality widely utilized in the management of musculoskeletal disorders. The objective of this systematic review was to evaluate the effectiveness of therapeutic ultrasound in the management of patients with knee, shoulder and hip pain. Methods Using PRISMA guidelines, a search of the PubMed, CENTRAL (The Cochrane Library), Web of Science and Scopus databases was performed to retrieve randomized controlled trials (RCTs) that evaluated therapeutic ultrasound (continuous and pulsed) in patients with chronic knee, shoulder and hip pain. Results The search strategy identified 8 trials for knee, 7 trials for shoulder and 0 trials for hip that met the criteria for inclusion. All 8 trials showed improvement in knee pain, and of these studies 3 showed statistical significance improvement for therapeutic ultrasound versus the comparator. For shoulder pain, all 7 trials showed reduction in pain, but should be noted that 4 of studies demonstrated that therapeutic ultrasound is inferior to the comparator modality, Conclusion Therapeutic ultrasound is frequently used in the treatment of knee, shoulder and hip pain and is often combined with other physiotherapeutic modalities. The literature on knee arthritis is most robust, with some evidence supporting therapeutic ultrasound, though the delivery method of ultrasound (pulsed vs continuous) is controversial. As a monotherapy, ultrasound treatment may not have a significant impact on functional improvement but can be a reasonable adjunct to consider with other common modalities. In all three pain syndromes, especially for hip pain, further trials are needed to define the true effect of low-intensity ultrasound therapy knee, shoulder and hip pain. No conclusive recommendations may be made for optimal settings or session duration.

Background: The role of perioperative antibiotics in cleft palate remains a topic of debate. Advocates stress their importance in preventing local and systemic infections and decreasing the incidence of oronasal fistula formation. However, few studies to date have directly evaluated the role of antibiotics and other antimicrobial measures in cleft palate surgery. Objective: The aim of this review is to evaluate the evidence surrounding the use of perioperative antibiotics and other antimicrobial interventions in cleft palate surgery. Additionally, we review the literature on the oral flora unique to the cleft palate patient population. Methods: This was accomplished utilizing PubMed, Medline, and the Cochrane Library with MeSH and generic terms. Articles were selected based on predefined inclusion and exclusion criteria. Results: This review highlights the lack of higher level evidence on perioperative antibiotic use and other antimicrobial interventions in cleft palatoplasty and calls for further research on the matter. Conclusions: The literature appears to support the use of preoperative antibiotics for cleft palatoplasty, but the benefits of prolonged postoperative antibiotic use remain questionable.

Pulp Revascularization

Background: Endodontic Regenerative Procedures, especially pulp revascularization therapy, have become a real option for the treatment for immature permanent teeth with open apices. This sort of approach has saved many teeth that otherwise would have been extracted. The technique is simple and effective, and can be accomplished by any odontologist. Objective: This article aimed to make a literature review to give support for a case report of an Endodontic Regenerative Procedure of a twelve-year-old male patient with immature open apice of tooth 21. Methodology: Articles were researched concerning pulp revascularization to reach root end formation. On line searches were accomplished, whose database include BVS/BIREME, Web of Science, PUBMED Central, Science Direct, Higher Level Personnel Improvement Coordinator (CAPES), The Cochrane Library, and PROSPERO). Results: the articles researched showed that Endodontic Regenerative Procedures are efficient in stimulating root end formation. The case report described matched the results offered by the articles, showing an immature open apice tooth that had its root end completely formed after pulp revascularization therapy. Conclusion: Pulp revascularization therapy is an efficient and practical treatment for immature teeth with open apices.

Migraine is a common and disabling neurological condition with a complex etiology. Recent advances in the understanding of the gut microbiome have shown the role of gut micro-organisms in disease outcomes for distant organs—including the brain. Interventions targeting the gut microbiome have been shown to be effective in multiple neurological diagnoses, but there is little research into the role of the microbiome in migraine. This systematic review seeks to assess the current research landscape of randomized placebo controlled trials utilizing probiotic interventions as migraine prophylaxis. Searches were conducted of scientific databases including PubMed, MEDLINE, and the Cochrane Library, following PRISMA guidelines. Of 68 screened studies, 2 were eligible for analysis. Due to methodological differences, meta-analysis was not possible. Qualitative comparison of the studies demonstrated a dichotomy of results—one trial reported no significant change in migraine frequency and intensity, while the second trial reported highly significant improvements. No clear ‘gold standard’ currently exists for microbiome research, let alone for migraine-related microbiome research. The heterogeneity of outcome measures used in the two trials included in this systematic review shows the need for a standardization of outcome measures, therefore a series of recommendations for future probiotic–migraine research are included.

Purpose Dyspnea is one of the most distressing symptoms experienced by terminally ill cancer patients. This study aimed to evaluate the role of interventions for the palliation of dyspnea. Methods We conducted a systematic review of randomized controlled trials assessing all pharmacologic and nonpharmacologic interventions for dyspnea palliation in cancer patients, and searched the Cochrane Library, MEDLINE, conference proceedings, and references. Two reviewers independently appraised the quality of trials and extracted data. Results Our search yielded 18 trials. Fourteen evaluated pharmacologic interventions: seven assessing opioids (a total of 256 patients), five assessing oxygen (137 patients), one assessing helium-enriched air, and one assessing furosemide. Four trials evaluated nonpharmacologic interventions (403 patients). The administration of subcutaneous morphine resulted in a significant reduction in dyspnea Visual Analog Scale (VAS) compared with placebo. No difference was observed in dyspnea VAS score when nebulized morphine was compared with subcutaneous morphine, although patients preferred the nebulized route. The addition of benzodiazepines to morphine was significantly more effective than morphine alone, without additional adverse effects. Oxygen was not superior to air for alleviating dyspnea, except for patients with hypoxemia. Nursing-led interventions improved breathlessness. Acupuncture was not beneficial. Conclusion Our review supports the use of opioids for dyspnea relief in cancer patients. The use of supplemental oxygen to alleviate dyspnea can be recommended only in patients with hypoxemia. Nursing-led nonpharmacologic interventions seem valuable. Only a few studies addressing this question were performed. Thus, further studies evaluating interventions for alleviating dyspnea are warranted.

Abstract Background Neonatal hyperbilirubinemia (NNH) is a common disease in newborns. This research study aimed to assess the associations between uridine diphospho-glucuronate-glucuronosyltransferase 1A1 (UGT1A1, c.-3279 T > G) polymorphisms and NNH risk. Methods We searched PubMed, the Cochrane Library, and the Embase electronic databases. All published eligible studies before July 1, 2019, were searched for this meta-analysis. Results We identified 7 independent studies including 1560 cases. The data showed that in the general population, compared with the GT + GG vs TT and GG vs TT, c.-3279 T > G (rs4124874) was significantly related to a higher NNH risk (GG vs TT: OR = 1.865, 95% CI: 1.031–3.373, P = 0.039; GT + GG vs TT: OR = 1.331, 95% CI: 1.055–1.679, P = 0.016). Although not statistically significant, the data showed that c.3279 T > G had a tendency to be associated with NNH under the allele model and GG vs GT + TT in the overall population (G vs T: OR = 1.288, 95% CI: 0.982–1.689, P = 0.067; GG vs TT + GT: OR = 1.583, 95% CI: 0.947–2.647, P = 0.080). Conclusion The UGT1A1 gene c.-3279 T > G (rs4124874) polymorphism increased susceptibility to NNH, especially for the comparison of GT + GG vs TT and GG vs TT. In the future, we can use homozygous state of the UGT1A1 gene c.-3279 T > G (rs4124874) polymorphism for the diagnosis and screening of molecular biomarkers in NNH patients.
