Leveraging a Joint learning Model to Extract Mixture Symptom Mentions from Traditional Chinese Medicine Clinical Notes.

This paper addresses the mixture symptom mention problem which appears in the structuring of Traditional Chinese Medicine (TCM). We accomplished this by disassembling mixture symptom mentions with entity relation extraction. Over 2,200 clinical notes were annotated to construct the training set. Then, an end-to-end joint learning model was established to extract the entity relations. A joint model leveraging a multihead mechanism was proposed to deal with the problem of relation overlapping. A pretrained transformer encoder was adopted to capture context information. Compared with the entity extraction pipeline, the constructed joint learning model was superior in recall, precision, and F1 measures, at 0.822, 0.825, and 0.818, respectively, 14% higher than the baseline model. The joint learning model could automatically extract features without any extra natural language processing tools. This is efficient in the disassembling of mixture symptom mentions. Furthermore, this superior performance at identifying overlapping relations could benefit the reassembling of separated symptom entities downstream.

Efficacy and Safety of Light Therapy as a Home Treatment for Motor and Non-Motor Symptoms of Parkinson Disease: A Meta-Analysis.

BACKGROUND Non-visual effects of the retina have been increasingly confirmed in developing Parkinson disease (PD). Light therapy (LT) has been proven to be an effective non-pharmacotherapy for improving the prognosis of PD, but the pathway of action is unclear, and there is a lack of a unified and standardized LT regimen. We aimed to evaluate the efficacy and safety of various LT measures in improving motor and non-motor symptoms in patients with idiopathic PD via a meta-analysis. MATERIAL AND METHODS CENTRAL, EMBASE, CINAHL, PEDro, and PubMed were searched for randomized controlled trials (RCTs) investigating the efficacy of LT for PD. Cochrane's Risk of bias tool and the GRADE approach were used to assess evidence quality. A meta-analysis and subgroup analyses evaluated the differences in efficacy produced by the different LT protocols. Trial sequential analysis (TSA) verified the analyses outcome and quantified the statistical relevance of the data.[color=#0e101a] [/color] RESULTS Patients receiving LT had significantly better scores for motor function (MD=-4.68, 95% Cl -8.25 to -1.12, P=0.01) compared with the control group exposed to dim-red light. In addition, in terms of non-motor symptoms, depression (SMD=-0.27, 95% Cl -0.52 to -0.02, P=0.04) and sleep disturbance-related scores (MD=3.45, 95% Cl 0.12 to 6.78, P=0.04) similarly showed significant optimization after receiving LT. CONCLUSIONS The results of this meta-analysis show strong evidence that LT has significant efficacy on motor and non-motor function in PD patients.

Favorable outcomes with reduced steroid use in juvenile dermatomyositis.

BACKGROUND: High-intensity glucocorticoid regimens are commonly used to induce and maintain remission in Juvenile Dermatomyositis but are associated with several adverse side-effects. Evidence-based treatment guidelines from North American and European pediatric rheumatology research societies both advocate induction with intravenous pulse steroids followed by high dose oral steroids (2 mg/kg/day), which are then tapered. This study reports the time to disease control with reduced glucocorticoid dosing. METHODS: We retrospectively reviewed the records at a single tertiary-care children's hospital of patients diagnosed with Juvenile Dermatomyositis between 2000 and 2014 who had a minimum of 2 years of follow-up. The primary outcome measure was time to control of muscle and skin disease. Additional outcome measures included glucocorticoid dosing, effect of treatment on height, frequency of calcinosis, and complications from treatment. RESULTS: Of the 69 patients followed during the study period, 31 fulfilled inclusion criteria. Median length of follow-up was 4.58 years, (IQR 3-7.5). Myositis control was achieved in a median of 7.1 months (IQR 0.9-63.4). Cutaneous disease control was achieved in a median of 16.7 months (IQR 4.3-89.5). The median starting dose of glucocorticoids was 0.85 mg/kg/day, (IQR 0.5-1.74). The median duration of steroid treatment was 9.1 months, (IQR 4.7-17.4), while the median duration of any pharmacotherapy was 29.2 months (IQR 10.4 to 121.3). Sustained disease control off medications was achieved in 21/31 (68%) patients by the end of review. Persistent calcinosis was identified in only one patient (3%). CONCLUSION: Current accepted treatment paradigms for Juvenile Dermatomyositis include oral glucocorticoids beginning at 2 mg/kg/day and reduced over a prolonged time period. However, our results suggest that treatment using reduced doses and duration with early use of steroid-sparing agents is comparably effective in achieving favorable outcomes in Juvenile Dermatomyositis.

Efficacy and safety of ReDuNing injection as a treatment for COVID-19 and its inhibitory effect against SARS-CoV-2.

BACKGROUND: Although the rapid emergence of coronavirus disease 2019 (COVID-19) poses a considerable threat to global public health, no specific treatment is available for COVID-19. ReDuNing injection (RDN) is a traditional Chinese medicine known to exert antibacterial, antiviral, antipyretic, and anti-inflammatory effects. In addition, RDN has been recommended in the diagnosis and treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated pneumonia by the National Health Council and the National Administration of Chinese Medicine. However, there is no information regarding its efficacy against COVID-19. AIM OF STUDY: This study was designed to determine the clinical efficacy of RDN in patients with COVID-19 and characterize its antiviral activity against SARS-CoV-2 in vitro. MATERIALS AND METHODS: A total of 50 adults with COVID-19 were included in this study, and the primary endpoint was recovery from clinical symptoms following 14 days of treatment. General improvements were defined as the disappearance of the major symptoms of infection including fever, fatigue, and cough. The secondary endpoints included the proportion of patients who achieved clinical symptom amelioration on days 7 and 10, time to clinical recovery, time to a negative nucleic acid test result, duration of hospitalization, and time to defervescence. Plaque reduction and cytopathic effect assays were also performed in vitro, and reverse-transcription quantitative PCR was performed to evaluate the expression of inflammatory cytokines (TNF-α, IP-10, MCP-1, IL-6, IFN-α, IFN-γ, IL-2 and CCL-5) during SARS-CoV-2 infection. RESULTS: The RDN group exhibited a shorter median time for the resolution of clinical symptoms (120 vs. 220 h, P < 0.0001), less time to a negative PCR test result (215 vs. 310 h, P = 0.0017), shorter hospitalization (14.8 vs. 18.5 days, P = 0.0002), and lower timeframe for defervescence (24.5 vs. 75 h, P = 0.0001) than the control group. In addition, time to improved imaging was also shorter in the RDN group than in the control group (6 vs.8.9 days, P = 0.0273); symptom resolution rates were higher in the RDN group than in the control group at 7 (96.30% vs. 39.13%, P < 0.0001) and 10 days (96.30% vs. 56.52%, P = 0.0008). No allergic reactions or anaphylactic responses were reported in this trial. RDN markedly inhibited SARS-CoV-2 proliferation and viral plaque formation in vitro. In addition, RDN significantly reduced inflammatory cytokine production in infected cells. CONCLUSIONS: RDN relieves clinical symptoms in patients with COVID-19 and reduces SARS-CoV-2 infection by regulating inflammatory cytokine-related disorders, suggestion that this medication might be a safe and effective treatment for COVID-19.

Real-world Compliance With Percutaneous Tibial Nerve Stimulation Maintenance Therapy in an American Population.

OBJECTIVE: To evaluate percutaneous tibial nerve stimulation (PTNS) maintenance therapy dropout rates and identify factors associated with compliance in an American population. METHODS: We retrospectively queried our PTNS database for patients from 2014-2019. Demographic, relevant clinical, and visit data were collected. Maintenance therapy was patient-driven and frequency of sessions was tapered based on symptomology. Upon completion of 12 initial sessions, we assessed dropout from maintenance at 3, 6, 9, and 12 months. Multiple variables were tested for correlation with dropout in patients continuing maintenance therapy for 1 year vs those who dropped out. RESULTS: One hundred and sixty-three PTNS patients were identified, of which 104 completed initial therapy and 81 proceeded with maintenance therapy. At 3, 6, 9, and 12 months, maintenance continuation rates were 77.8% (63/81), 58.0% (47/81), 45.6% (37/81), and 39.5% (32/41), respectively. Primary reasons for dropout were worsening of urinary symptoms/lack of efficacy (n = 21), time commitment (n = 9), loss of insurance (n = 5), medical comorbidities (n = 4), request for alternative OAB treatment (n = 2), and unknown (n = 8). On both univariate and multivariate analysis, perceived symptom improvement (P<.01; HR = 0.02, P< .01) was associated with continuing maintenance therapy. On only univariate analysis, neurological history (P = .02) and multiple sclerosis history (0.02) were associated with continuing therapy. CONCLUSION: Only 39.5% of patients continue to undergo maintenance PTNS therapy after 1 year. Future studies are required to understand and ameliorate factors for low compliance in PTNS maintenance therapy.

[Caring for the caregiver: The emotional impact of the coronavirus epidemic on nurses and other health professionals]. / Cuidar al que cuida: el impacto emocional de la epidemia de coronavirus en las enfermeras y otros profesionales de la salud.

The health crisis caused by the COVID-19 virus pandemic has once again highlighted the role of health professionals as a key element for their containment, who suffer from high tension marked by healthcare pressure and the lack of means of protection. Given this tension, it is relevant to analyze the emotional impact on health professionals of the coronavirus pandemic and the coping resources to reduce or mitigate this impact. Stress, sleep disorders and depressive symptoms stand out. Some strategies are recommended that have been used by professionals who have previously been under pressure from COVID-19 and have been helpful to them. Finally, some recommendations whose efficacy is known for managing emotional impact are pointed out.

Effects of Automatic Abdominal Massage Device in Treatment of Chronic Constipation Patients: A Prospective Study.

BACKGROUND AND AIM: Manual abdominal massage has been shown to effectively treat slow-transit constipation, but it is labor-intensive. To offer an alternative treatment option for constipation, the Bamk-001 automatic abdominal massage device was developed. The aim of this study was to assess the effect of the Bamk-001 device on symptom profiles and colon transit time (CTT) in patients with chronic constipation. METHODS: Thirty-seven patients with chronic functional constipation diagnosed using the Rome IV criteria were enrolled prospectively from December 2018 to February 2019. All patients received device-assisted automatic abdominal massage for 15 min twice daily, once in the morning before breakfast and once at night, for 14 days. CTT was measured before and at the end of the study period. Slow-transit constipation and very-slow-transit constipation were defined as CTT ≥ 48 h and ≥ 72 h, respectively. Patients' symptom profiles regarding overall defecation satisfaction and device-related adverse events were analyzed. RESULTS: Among the 37 patients, the mean age was 40.1 ± 11.8, and 5.4% (n = 2) were men. The Bamk-001 device significantly improved CTT from 54.0 (33.6-75.6) to 28.8 (18.0-52.8) h (p = 0.001) in patients with chronic constipation. In subgroup analysis, CTT improved significantly from 54.0 (33.6-75.6) to 28.8 (18.0-52.8) h (p = 0.003) and from 88.2 (74.4-124.8) to 45.6 (27.3-74.1) h (p = 0.005) in the slow-transit and very-slow-transit constipation groups, respectively (p = 0.001). Moreover, all patient symptoms were alleviated after treatment. No serious adverse events were reported. CONCLUSION: The Bamk-001 automatic abdominal massage device showed significant care efficacy, including the improvement in CTT and symptom profiles in patients with slow-transit constipation. The use of an automatic abdominal massage device as an adjunct in the management of constipation is a potentially beneficial intervention for patients with slow-transit constipation.

Formulation, Standardization, and a Preliminary Before-After Clinical Trial on Effect of a Traditional Herbal Formula (Maqliasa) on Manifestations of Ulcerative Colitis.

BACKGROUND: Ulcerative Colitis (UC) is a chronic condition that represents a group of intestinal disorders causing prolonged inflammation of the digestive tract. Nowadays, efforts to investigate new remedies have led to a committed movement toward the integration of traditional and complementary medicine into mainstream medicine. In Traditional Persian Medicine (TPM), Maqliasa is one of the most frequent gastrointestinal prescriptions which is claimed to be effective in both remission and recurrent phases of UC. OBJECTIVE: The aim of this pilot study was to examine the effect of Maqliasa on UC symptoms. METHODS: Through a non-randomized before-after uncontrolled clinical trial, 13 outpatients with active UC were enrolled in the study. They continued their conventional drug regimens plus Maqliasa capsules (2 capsules t.i.d.) for 28 days. Three visits were arranged for each patient- the first admission, day 14th admission and day 28th admission. The patients were evaluated by Lichtiger Colitis Activity Index. Wilcoxon signed-rank test was used for statistical analysis. RESULTS: The Lichtiger colitis activity index improved in the study group was compared to the corresponding baseline values: baseline score: 7.8 ± 0.5; after two weeks: 5.9 ± 0.6 (P=0.002); after four weeks: 3.6 ± 0.5 (P=0.001). CONCLUSIONS: This study showed the promising effect of Maqliasa in the treatment of active UC. However, due to some of the limitations of the study, conducting future high-quality randomized clinical trials would be crucial.

Use Characteristics and Triage Acuity of a Digital Symptom Checker in a Large Integrated Health System: Population-Based Descriptive Study.

BACKGROUND: Pressure on the US health care system has been increasing due to a combination of aging populations, rising health care expenditures, and most recently, the COVID-19 pandemic. Responses to this pressure are hindered in part by reliance on a limited supply of highly trained health care professionals, creating a need for scalable technological solutions. Digital symptom checkers are artificial intelligence-supported software tools that use a conversational "chatbot" format to support rapid diagnosis and consistent triage. The COVID-19 pandemic has brought new attention to these tools due to the need to avoid face-to-face contact and preserve urgent care capacity. However, evidence-based deployment of these chatbots requires an understanding of user demographics and associated triage recommendations generated by a large general population. OBJECTIVE: In this study, we evaluate the user demographics and levels of triage acuity provided by a symptom checker chatbot deployed in partnership with a large integrated health system in the United States. METHODS: This population-based descriptive study included all web-based symptom assessments completed on the website and patient portal of the Sutter Health system (24 hospitals in Northern California) from April 24, 2019, to February 1, 2020. User demographics were compared to relevant US Census population data. RESULTS: A total of 26,646 symptom assessments were completed during the study period. Most assessments (17,816/26,646, 66.9%) were completed by female users. The mean user age was 34.3 years (SD 14.4 years), compared to a median age of 37.3 years of the general population. The most common initial symptom was abdominal pain (2060/26,646, 7.7%). A substantial number of assessments (12,357/26,646, 46.4%) were completed outside of typical physician office hours. Most users were advised to seek medical care on the same day (7299/26,646, 27.4%) or within 2-3 days (6301/26,646, 23.6%). Over a quarter of the assessments indicated a high degree of urgency (7723/26,646, 29.0%). CONCLUSIONS: Users of the symptom checker chatbot were broadly representative of our patient population, although they skewed toward younger and female users. The triage recommendations were comparable to those of nurse-staffed telephone triage lines. Although the emergence of COVID-19 has increased the interest in remote medical assessment tools, it is important to take an evidence-based approach to their deployment.

Effect of an oral preparation containing hyaluronic acid, chondroitin sulfate, hydrolyzed collagen type II and hydrolyzed keratin on synovial fluid features and clinical indices in knee osteoarthritis. A pilot study.

The aim of this study was to evaluate the effect of an oral preparation containing a naturally occurring matrix of hydrolyzed collagen type II, chondroitin sulfate (CS), and hyaluronic acid (HA), and bioactive oligopeptides of natural hydrolyzed keratin (K) in patients affected by knee OA through the evaluation of synovial fluid (SF) and clinical changes before and after treatment. Thirty patients with knee OA and swollen joint were included in the study and submitted to arthrocentesis. Patients were randomized in two groups: 1) the treatment group (N.15) took a dietary supplement containing 120 mg HA, 240 mg CS and 300 mg K once a day for 4 weeks; 2) the control group (N.15) was only submitted to arthrocentesis. Patient symptoms were evaluated at the beginning and at the end of the study by the WOMAC self-assessment questionnaire, the Lequesne algofunctional index, and the VAS forms. SF changes were evaluated by measuring local inflammatory indices, cytokines IL-1ß, IL-8, IL-6, IL-10 and GM-CSF. The group of patients treated with the oral supplement showed an improvement in the clinical indices WOMAC (p<0.01), Lequesne (p=0.014) and VAS pain (p<0.01). On the contrary, no significant changes were found in the control group. The SF collected from the treated group showed a reduction of IL-8 (p=0.015), IL-6 and IL-10 levels, while no changes in cytokines were observed in the control group. This pilot study suggests that an oral administration of a preparation containing a combination of HA, CS and K can improve some clinical parameters and affect cytokine concentrations in SF in patients with knee OA.

Evaluation of a National Comprehensive Cancer Network Guidelines-Based Decision Support Tool in Patients With Non-Small Cell Lung Cancer: A Nonrandomized Clinical Trial.

Importance: The association of guideline-based decision support with the quality of care in patients with non-small cell lung cancer (NSCLC) is not known. Objective: To evaluate the association of exposure to the National Comprehensive Cancer Center (NCCN) guidelines with guideline-concordant care and patients' decisional conflict. Design, Setting, and Participants: A nonrandomized clinical trial, conducted at a tertiary care academic institution, enrolled patients from February 23, 2015, to September 28, 2017. Data analysis was conducted from July 19, 2019, to April 22, 2020. A cohort of 76 patients with NSCLC seen at diagnosis or disease progression and a retrospective cohort of 157 patients treated before the trial were included. Adherence to 6 NCCN recommendations were evaluated: (1) smoking cessation counseling, (2) adjuvant chemotherapy for patients with stage IB to IIB NSCLC after surgery, (3) pathologic mediastinal staging in patients with stage III NSCLC before surgery, (4) pathologic mediastinal staging in patients with stage III NSCLC before nonsurgical treatment, (5) definitive chemoradiotherapy for patients with stage III NSCLC not having surgery, and (6) molecular testing for epidermal growth factor receptor and anaplastic lymphoma kinase alterations for patients with stage IV NSCLC. Subgroup analysis was conducted to compare the rates of guideline concordance between the prospective and retrospective cohorts. Secondary end points included decisional conflict and satisfaction. Interventions: An online tool customizing the NCCN guidelines to patients' clinical and pathologic features was used during consultation, facilitated by a trained coordinator. Main Outcomes and Measures: Concordance of practice with 6 NCCN treatment recommendations on NSCLC and patients' decisional conflict. Results: Of the 76 patients with NSCLC, 44 were men (57.9%), median age at diagnosis was 68 years (interquartile range [IQR], 41-87 years), and 59 patients (77.6%) had adenocarcinoma. In the retrospective cohort, 91 of 157 patients (58.0%) were men, median age at diagnosis was 66 years (IQR, 61-65 years), and 105 patients (66.9%) had adenocarcinoma. After the intervention, patients received more smoking cessation counseling (4 of 5 [80.0%] vs 1 of 24 [4.2%], P < .001) and less adjuvant chemotherapy (0 of 7 vs 7 of 11 [63.6%]; P = .012). There was no significant change in mutation testing of non-squamous cell stage IV disease (20 of 20 [100%] vs 48 of 57 [84.2%]; P = .10). There was no significant change in pathologic mediastinal staging or initial chemoradiotherapy for patients with stage III disease. After consultation with the tool, decisional conflict scores improved by a median of 20 points (IQR, 3-34; P < .001). Conclusions and Relevance: The findings of this study suggest that exposure to the NCCN guidelines is associated with increased guideline-concordant care for 2 of 6 preselected recommendations and improvement in decisional conflict. Trial Registration: ClinicalTrials.gov Identifier: NCT03982459.

Variation Between Multidisciplinary Tumor Boards in Clinical Staging and Treatment Recommendations for Patients With Locally Advanced Non-small Cell Lung Cancer.

BACKGROUND: Accurate diagnosis and staging are crucial to ensure uniform allocation to the optimal treatment methods for non-small cell lung cancer (NSCLC) patients, but may differ among multidisciplinary tumor boards (MDTs). Discordance between clinical and pathologic TNM stage is particularly important for patients with locally advanced NSCLC (stage IIIA) because it may influence their chance of allocation to curative-intent treatment. We therefore aimed to study agreement on staging and treatment to gain insight into MDT decision-making. RESEARCH QUESTION: What is the level of agreement on clinical staging and treatment recommendations among MDTs in stage IIIA NSCLC patients? STUDY DESIGN AND METHODS: Eleven MDTs each evaluated the same 10 pathologic stage IIIA NSCLC patients in their weekly meeting (n = 110). Patients were selected purposively for their challenging nature. All MDTs received exactly the same clinical information and images per patient. We tested agreement in cT stage, cN stage, cM stage (TNM 8th edition), and treatment proposal among MDTs using Randolph's free-marginal multirater kappa. RESULTS: Considerable variation among the MDTs was seen in T staging (κ, 0.55 [95% CI, 0.34-0.75]), N staging (κ, 0.59 [95% CI, 0.35-0.83]), overall TNM staging (κ, 0.53 [95% CI, 0.35-0.72]), and treatment recommendations (κ, 0.44 [95% CI, 0.32-0.56]). Most variation in T stage was seen in patients with suspicion of invasion of surrounding structures, which influenced such treatment recommendations as induction therapy and type. For N stage, distinction between N1 and N2 disease was an important source of discordance among MDTs. Variation occurred between 2 patients even regarding M stage. A wide range of additional diagnostics was proposed by the MDTs. INTERPRETATION: This study demonstrated high variation in staging and treatment of patients with stage IIIA NSCLC among MDTs in different hospitals. Although some variation may be unavoidable in these challenging patients, we should strive for more uniformity.

Assessing the depth of language processing in patients with disorders of consciousness.

Assessing residual consciousness and cognitive abilities in unresponsive patients is a major clinical concern and a challenge for cognitive neuroscience. Although neuroimaging studies have demonstrated a potential for informing diagnosis and prognosis in unresponsive patients, these methods involve sophisticated brain imaging technologies, which limit their clinical application. In this study, we adopted a new language paradigm that elicited rhythmic brain responses tracking the single-word, phrase and sentence rhythms in speech, to examine whether bedside electroencephalography (EEG) recordings can help inform diagnosis and prognosis. EEG-derived neural signals, including both speech-tracking responses and temporal dynamics of global brain states, were associated with behavioral diagnosis of consciousness. Crucially, multiple EEG measures in the language paradigm were robust to predict future outcomes in individual patients. Thus, EEG-based language assessment provides a new and reliable approach to objectively characterize and predict states of consciousness and to longitudinally track individual patients' language processing abilities at the bedside.

A Randomized Internet-Based Pilot Feasibility and Planning Study of Cherry Extract and Diet Modification in Gout.

OBJECTIVE: The aim of this study was to conduct a 9-month pilot Internet randomized controlled trial (RCT) of cherry extract and diet modification in gout to assess the feasibility of an Internet study and obtain effect estimates. METHODS: After providing online informed consent in response to Internet advertisements and social media or clinic flyers, 84 people with physician-confirmed gout were randomized to either cherry extract 3,600 mg/d (n = 41) or dietitian-assisted diet modification for gout (n = 43). All study outcomes were collected via Internet and phone calls. The primary objective was the feasibility of an Internet study, and secondary objectives were to obtain effect estimates for gout flares, functional ability assessed with the Health Assessment Questionnaire (HAQ), and adverse events (AEs) for future trials. RESULTS: Of the 84 people randomized, overall completion rates were more than 80% for most study procedures up to 6 months and similar for the 2 active comparators. Improvements were seen in gout flares and HAQ scores in cherry extract and diet modification groups at 9 months compared with baseline: gout flares per month, 0.22 versus 0.36 (p = 0.049) and 0.28 versus 0.31 (p = 0.76); proportion with any gout flare, 56% versus 98% (p < 0.0001) and 65% versus 98% (p = 0.0002); and mean ± standard deviation HAQ score, 0.28 ± 0.54 versus 0.55 ± 0.68 (p = 0.001) and 0.23 ± 0.40 versus 0.48 ± 0.61 (p = 0.06), respectively. Any AEs and gastrointestinal symptoms/AEs at 9 months in cherry extract and diet modification groups were 3% versus 0% and 28% versus 27%, respectively. CONCLUSIONS: An Internet gout RCT is feasible for nonpharmacological gout treatments. A hypothesis-testing, large Internet RCT of cherry extract versus placebo is needed.

Clinical features and multidisciplinary treatment outcome of COVID-19 pneumonia: A report of three cases.

The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic threatening global public health. In the current paper, we describe our successful treatment of three COVID-19 pneumonia patients cases including severe cases and cases with mortality risk factors. One 32-year-old male COVID-19 patient was diagnosed with severe COVID-19 pneumonia and moderate ARDS. The second COVID-19 pneumonia patient had a history of diabetes and chronic bronchitis. The third case of COVID-19 pneumonia was an 82-year old female patient. All three cases had severe COVID pneumonia and therefore were aggressively managed with a multidisciplinary and personalized therapeutic approach that included nutritional support, antiviral pharmacotherapy, active control of comorbidities, prevention of complication development and psychological intervention. Our experience highlights the importance of the use of a multidisciplinary therapeutic approach that tailors to the specific condition of the patient in achieving a favorable clinical outcome.

Efficacy of Lactobacillus paracasei HA-196 and Bifidobacterium longum R0175 in Alleviating Symptoms of Irritable Bowel Syndrome (IBS): A Randomized, Placebo-Controlled Study.

Specific probiotic strains can alleviate the gastrointestinal (GI) symptoms and psychiatric comorbidities of irritable bowel syndrome (IBS). In this randomized, double-blind, placebo-controlled study, the efficacy of Lactobacillus paracasei HA-196 (L. paracasei) and Bifidobacterium longum R0175 (B. longum) in reducing the GI and psychological symptoms of IBS was evaluated in 251 adults with either constipation (IBS-C), diarrhea (IBS-D), or mixed-pattern (IBS-M). Following a 2-week run-in period, participants were randomized to one of three interventions: L. paracasei (n = 84), B. longum (n = 83) or placebo (n = 81). IBS symptoms, stool frequency and consistency and quality of life were assessed by questionnaires. The differences from baseline in the severity of IBS symptoms at 4 and 8 weeks were similar between groups. Participants in this study were classified, after randomization, into subtypes according to Rome III. Within the L. paracasei group, complete spontaneous and spontaneous bowel movement frequency increased in participants with IBS-C (n = 10) after 8 weeks of supplementation (both p < 0.05) and decreased in participants with IBS-D (n = 10, p = 0.013). Both L. paracasei and B. longum supplementation improved the quality of life in emotional well-being and social functioning compared with baseline (all p < 0.05). In conclusion, L. paracasei and B. longum may reduce GI symptom severity and improve the psychological well-being of individuals with certain IBS subtypes.
