Hepatitis B Virus-Hepatitis D Virus mother-to-child co-transmission: A retrospective study in a developed country.

BACKGROUND & AIMS: Hepatitis B Virus (HBV) DNA during chronic infection can reach levels at which mother-to-child (MTC) transmission frequently occurs despite passive-active immunization of newborns. Hepatitis D Virus (HDV) RNA can reach high levels, we assessed HBV/HDV MTC co-transmission. METHODS: Monocentric retrospective study (registered in ClinicalTrials.gov (NCT02044055)), after informed consent in HBV/HDV co-infected women pregnant between 01/01/2004 and 01/01/2015 in Paris, France. The children were tested when 24 months of age or older. RESULTS: Twenty-two (3%) of 742 HBV infected women, HDV co-infected, gave birth to 54 children during the study period. HBV DNA was above 5 Log10 I.U/mL in 10 pregnancies previous any treatment, with HDV RNA of less than 2.3 Log10 I.U/mL. HDV RNA was above 5 Log10 I.U/mL in eight pregnancies previous any treatment, with HBV DNA of less than 1.5 Log10 I.U/mL. Inverse patterns of HBV DNA and HDV RNA were observed in 17 of 35 (49%) pregnancies: 13 (76%) received no HBV treatment; four (24%) were treated. HBV DNA was under 5 Log10 I.U/mL in 46 of the 50 assessed women (92%) at birth. Of the 36 assessed children, given passive-active immunization, 24 (66%) were protected, 10 (28%) were neither infected nor protected, one was chronically HBV infected, and one had a past HBV infection. HDV Ab was negative in the 36 children. CONCLUSIONS: These results suggest that HBV/HDV MTC co-transmission is exceptional. Studies are needed, mainly in developing countries.

Effect of body weight and composition on efavirenz, atazanavir or darunavir concentration.

BACKGROUND: To compare the steady state plasma concentrations (Css) of three antiretroviral drugs in both normal and overweight patients, and to determine the relationship between Css and fat mass (FM) or lean body mass. METHODS: Patients treated for more than 6 months once daily with one of the antiretroviral drugs: efavirenz (EFV) 600mg, atazanavir boosted with ritonavir (ATV-r) 300mg/100mg, or darunavir boosted with ritonavir (DRV-r) 800mg/100mg, combined with two nucleoside analogues, were enrolled prospectively. One at steady state, plasma samples for the assessment of drug concentration were taken and body composition was assessed by bioelectrical impedance. RESULTS: One hundred and thirty-nine patients were enrolled (46, 45 and 48 in the groups EFV, ATV-r and DRV-r respectively). Their mean age was 46.2±10.4 years, 58% were male, 55.4% were from Sub Sahara African (SSA); body mass index (BMI) was 25.4±4.4kg/m2. Mean drug plasma Css of the three drugs did not differ according to BMI group. DRV-r Css tended to be higher in patients with BMI≥25kg/m2 (2896.7±1689 versus 2091.9±1038, P=0.09) and was significantly correlated with FM (r=0.3, P=0.02). In subgroup analysis, the effect of FM on DRV-r Css was significant in patients from SSA (r=0.4, P=0.04). CONCLUSIONS: Css result from many factors and body composition has been shown to only weakly influence interindividual variability but should be investigated in morbidly obese patients treated with DRV-r.

Untreated highly viraemic pregnant women from Asia or sub-Saharan Africa often transmit hepatitis B virus despite serovaccination to newborns.

BACKGROUND & AIMS: Mother-to-child (MTC) hepatitis B virus (HBV) transmission has been mainly studied in Asia. The geographical origins of women and HBV genotypes differ in Europe. The aims were to determine the rate and risk factors of MTC HBV transmission from women with high HBV DNA loads in a maternity hospital in Paris, France. METHODS: Retrospective study of HIV-negative, HBs Ag-positive pregnant women with HBV DNA loads above 5 Log10 I.U/ml who were not given lamivudine or tenofovirDF during pregnancy between 2004 and 2011. RESULTS: Among 11 417 pregnant women, 437 (4%) showed a positive HBs Ag. Among these women, 52 had HBV DNA loads above 5 Log10 I.U/ml: 41, 10 and 1 born in Asia, sub-Saharan Africa and Europe respectively. Among the 52 women, 40 were eligible for the analysis: no antiviral therapy during pregnancy; children over 9 months old. Twenty-eight (70%) women were assessed, corresponding to 41 childbirths. Eleven children (27%) had positive HBs Ag, 14 (34%) had positive HBc and HBs Ab, 16 (39%) had positive HBs Ab only. The risk of having positive HBs Ag, according to maternal HBV DNA loads, was 14% for HBV DNA loads less or equal to 8 Log10 I.U/ml, 42% for HBV DNA loads over 8 Log10 I.U/ml, P = 0.04, but not related to the women's origin, HBV genotype. CONCLUSIONS: This study confirms that serovaccination does not fully protect newborns from MTC HBV transmission, when maternal HBV DNA loads exceed 5 Log10 I.U/ml, regardless of the women's origin or HBV genotype.

Methadone dose in heroin-dependent patients: role of clinical factors, comedications, genetic polymorphisms and enzyme activity.

AIMS: Methadone is characterized by wide intersubject variability regarding the dose needed to obtain full therapeutic response. We assessed the influence of sociodemographic, ethnic, clinical, metabolic and genotypic variables on methadone maintenance dose requirement in opioid-dependent responder patients. METHODS: Eighty-one stable patients (60 men and 21 women, 43.7 ± 8.1 years old, 63.1 ± 50.9 mg day(-1) methadone), divided into quartiles with respect to the median daily dose, were enrolled and underwent clinical examination, treatment history and determination of liver/intestinal cytochrome P450 (CYP) 3A4 activity measured by the midazolam test, R,S-methadone trough concentration and clinically significant polymorphisms of the OPRM1, DRD2, COMT, ABCB1, CYP2B6, CYP3A5, CYP2C19 and CYP2D6 genes. RESULTS: Methadone maintenance dose was correlated to the highest dose ever used (r(2) = 0.57, P < 0.0001). Fractioned methadone intake (odds ratio 4.87, 95% confidence interval 1.27-18.6, P = 0.02), bodyweight (odds ratio 1.57, 95% confidence interval 1.01-2.44, P = 0.04), history of cocaine dependence (80 vs. 44 mg day(-1) in never-addict patients, P = 0.005) and ethnicity (Asian > Caucasian > African, P = 0.04) were independently associated with high-dose methadone in multiple regression analysis. A modest correlation was observed between liver/intestinal CYP3A4 activity and methadone dose at steady state (Spearman rank correlation coefficient [rs ] = 0.21, P = 0.06) but not with highest dose ever used (rs = 0.15, P = 0.18) or dose-normalized R,S-methadone trough concentrations (rs = -0.05, P = 0.64). Concomitant CYP3A4 inhibitors only affected the relationship between methadone dose and R,S-methadone trough concentration. None of the genetic polymorphisms explored was predictive of the methadone maintenance dose. CONCLUSIONS: Methadone maintenance dose was predicted by sociodemographic and clinical variables rather than genetic polymorphisms or liver/intestinal CYP3A4 activity in stable patients.

[Use of oral drugs and short bowel syndrome: an analysis of practices]. / Utilisation des médicaments par voie orale et syndrome de grêle court : analyse des pratiques.

OBJECTIVE: To describe drug prescription patterns in patients with short bowel syndrome (SBS). METHODS: The drug prescriptions of patients suffering from SBS type 1 to 3 were compared. RESULTS: Seventy-nine percent of the drugs were prescribed by oral route, and this proportion was significantly higher in patients with type 3 compared to tose with type 1. Twenty-nine percent of prescriptions were dietary supplement-drugs, 14.3% were gastrointestinal drugs and 11.4% were cardiovascular drugs. Oral prescription medications for SBS concerned many drug categories. The number of gastrointestinal or dietary supplement drugs was comparable between the 3 types. Drug doses were not increased compared with the recommendations, except for gastrointestinal drugs. CONCLUSION: The oral administration is common and at usual dosage in patients with SBS despite a lack of studies on absorption that may help to individualize drug prescription.

Myofascial stiffness of plantar fascia and Achilles tendon in individuals with plantar fasciopathy: An observational cross-sectional study.

BACKGROUND: Assessment of myofascial tissue stiffness have a role in identifying physical impairments in plantar fasciopathy (PF). It is still unclear which specific functional and tissue differences exist between individuals with PF. AIM: To compare myofascial stiffness of plantar fascia, Achilles tendon, and triceps surae between symptomatic and asymptomatic limbs in individuals with PF and between individuals with and without PF. METHODS: Thirty nine individuals diagnosed with PF and individuals with no history of PF were recruited. Myofascial stiffness of the plantar fascia, Achilles tendon, and triceps surae, range of motion, and clinical tests were performed. Mean difference (MD) and 95% confidence interval (CI) were calculated. RESULTS: Individuals with PF showed lower mean stiffness in Achilles tendon insertion (MD = -1.00 N/mm; 95%CI: -1.80,-0.21) on the symptomatic limb compared to the corresponding symptomatic limb in control group, a lower mean stiffness in plantar fascia (MD = -0.16 N/mm; 95%CI: -0.30, -0.01) on the symptomatic limb compared to asymptomatic limb, and a lower mean stiffness in the region 3 cm above the Achilles tendon insertion (MD = -0.79; 95%CI: -1.59, -0.00) compared to control. Individuals with PF showed fewer repetitions in heel rise test (MD = -3.97 reps; 95%CI: -5.83, -2.12) and in the step-down test (MD = -5.23 reps; 95%CI: -7.02, -3.44) compared to control. CONCLUSIONS: Individuals with PF present reduced stiffness in Achilles tendon insertion and plantar fascia. The reduced stiffness was more evident in Achilles tendon in individuals with PF compared to individuals without PF. Individuals with PF showed lower performance in clinical tests.

Efficacy of early clinical evaluation in predicting direct home discharge of elderly patients after hospitalization in internal medicine.

OBJECTIVES: Early evaluation of direct home discharge (DHD) after hospitalization of elderly patients is important to organize discharge planning quickly. Many scores, scales, and indices have been developed to improve discharge planning. Is clinical judgment better than functional status, comorbidity, or cognitive function scales in predicting DHD of elderly patients after hospitalization? METHODS: Ninety-seven patients, aged 75 years or older, admitted from the emergency department to an internal medicine department in a French teaching hospital between December 1, 2006 and May 1, 2007, were enrolled prospectively in the study. Demographic, clinical, and laboratory characteristics and functional status, comorbidity, and cognitive function scales were determined. The primary outcome was the percentage of correct discharge prediction made by junior and senior doctors within the first 48 hours upon admission. Univariate analysis and logistic regression were assessed to determine predictive variables of patients' discharge. RESULTS: Junior and senior doctors obtained correct prediction in 74.2% and 73.2% of cases, respectively (P > 0.99). Activities of daily living, instrumental activities of daily living, and duration of hospitalization were predictive of DHD (95% confidence interval [CI] -6.1 to 0.2, P = 0.037; 95% CI -2.1 to 9.9, P = 0.003; 95% CI -3 to 9.1, P = 0.0001, respectively) in the univariate analysis. Instrumental activities of daily living was an independent predictive variable of patients' discharge in a logistic regression. No difference between clinical evaluation and the use of an independent predictive variable regarding the prediction of DHD was found. CONCLUSIONS: Early clinical evaluation is as effective as the use of functional status scales to predict DHD of hospitalized elderly patients.

Influence of knee flexion angle and age on triceps surae muscle activity during heel raises.

Triceps surae and Achilles tendon injuries are frequent in sports medicine, particularly in middle-aged adults. Muscle imbalances and weakness are suggested to be involved in the etiology of these conditions, with heel-raise testing often used to assess and treat triceps surae (TS) injuries. Although heel raises are recommended with the knee straight for gastrocnemius and bent for soleus (SOL), the extent of muscle selectivity in these positions is not clear. This study aimed to determine the influence of knee angle and age on TS muscle activity during heel raises. Forty-eight healthy men and women were recruited from a younger-aged (18-25 years) and middle-aged (35-45 years) population. All the subjects performed unilateral heel raises in 0° and 45° knee flexion (KF). Soleus, gastrocnemius medialis (GM) and gastrocnemius lateralis (GL) surface electromyography signals were processed to compute root-mean-square amplitudes, and data were analyzed using mixed-effects models and stepwise regression. The mean TS activity during heel raises was 23% of maximum voluntary isometric contraction when performed in 0° KF and 21% when in 45°. Amplitudes were significantly different between TS muscles (p < 0.001) and KF angles (p < 0.001), with a significant interaction (p < 0.001). However, the age of the population did not influence the results (p = 0.193). The findings demonstrate that SOL activity was 4% greater when tested in 45° compared with 0° KF and 5% lower in the GM and GL. The results are consistent with the recommended use of heel raises in select knee positions for assessing, training, and rehabilitating the SOL and gastrocnemius muscles; however, the 4-5% documented change in activity might not be enough to significantly influence clinical outcome measures or muscle-specific benefits. Contrary to expectations, TS activity did not distinguish between middle-aged and younger-aged adults, despite the higher injury prevalence in middle age.

Influence of knee flexion angle and age on triceps surae muscle fatigue during heel raises.

The triceps surae (TS) muscle-tendon unit is 1 of the most commonly injured in elite and recreational athletes, with a high prevalence in middle-aged adults. The performance of maximal numbers of unilateral heel raises is used to assess, train, and rehabilitate TS endurance and conventionally prescribed in 0° knee flexion (KF) for the gastrocnemius and 45° for the soleus (SOL). However, the extent of muscle selectivity conferred through the change in the knee angle is lacking for heel raises performed to volitional fatigue. This study investigated the influence of knee angle on TS muscle fatigue during heel raises and determined whether fatigue differed between middle-aged and younger-aged adults. Forty-eight healthy individuals aged 18-25 and 35-45 years performed maximal numbers of unilateral heel raises in 0° and 45° KF. Median frequencies and linear regression slopes were calculated from the SOL, gastrocnemius medialis (GM), and gastrocnemius lateralis (GL) surface electromyographic signals. Stepwise mixed-effect regressions were used for analysis. The subjects completed an average of 45 and 48 heel raises in 0° and 45° KF, respectively. The results indicated that the 3 muscles fatigued during testing as all median frequencies decreased, and regression slopes were negative. Consistent with muscle physiology and fiber typing, fatigue was greater in the GM and GL than in the SOL (p < 0.001). However, knee angle did not influence TS muscle fatigue parameters (p = 0.814), with similar SOL, GM, and GL fatigue in 0° and 45° KF. These findings are in contrast with the traditionally described clinical use of heel raises in select knee angles for the gastrocnemius and the SOL. Furthermore, no difference in TS fatigue between the 2 age groups was able to be determined, despite the reported higher prevalence of injury in middle-aged individuals.

Amoxicillin/clavulanic acid-warfarin drug interaction: a randomized controlled trial.

AIMS: To investigate whether an interaction exists between amoxicillin/clavulanic acid (amoxiclav) and warfarin in patients treated with stable oral anticoagulant therapy. METHODS: In a double-blind, cross-over, placebo-controlled study, 12 patients on stable warfarin therapy, received a 7 day amoxiclav regimen or placebo. RESULTS: The mean maximum increase in INR observed was 0.22 ± 0.3 with amoxiclav vs. 0.24 ± 0.6 with placebo (P=0.94). The day 7-day 1 factor II, R(-) and S(-) warfarin plasma concentrations were similar during the amoxiclav and placebo study periods (P=0.81, P=0.45, P=0.75, respectively). CONCLUSION: Amoxiclav did not modify anticoagulation in patients treated with stable warfarin therapy and without infection.

Interaction between acetaminophen and warfarin in adults receiving long-term oral anticoagulants: a randomized controlled trial.

PURPOSE: We investigated whether acetaminophen, given at 2 g/day and 3 g/day might potentiate the anticoagulant effect of warfarin. METHODS: Forty-five patients on stable warfarin therapy, enrolled in this prospective, randomized, parallel (three arms), placebo-controlled study, received a 10-day regimen of acetaminophen (2 g/day or 3 g/day) or placebo. RESULTS: The mean maximal INR increase was 0.70 ± 0.49 and 0.67 ± 0.62 in patients receiving acetaminophen at 2 g/day and 3 g/day, respectively (P=0.01 for the respective comparisons versus placebo). The INR increase became significant on day 3 and was independently and significantly predicted by a maximal decrease in factor II (R(2)=0.36, P<0.0001), factor VII (R (2)=0.46, P<0.0001) and a maximal increase in acetaminophen plasma concentrations (R(2)=0.563, P<0.0001). CONCLUSION: Acetaminophen, at 2 g/day or 3 g/day, enhanced the anticoagulant effect of warfarin in stable patients, thus requiring close INR monitoring in the clinical setting.

Pneumococcal vaccination coverage in France by general practitioners in adults with a high risk of pneumococcal disease.

Streptococcus pneumoniae, the main cause of community-acquired pneumonia (CAP), also leads to exacerbations, hospitalizations, and mortality in chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF). The risk of CAP is increased in patients with diabetes mellitus (DM), and the risk of invasive pneumococcal disease is increased in HIV-infected patients. Pneumococcal vaccination is recommended for these patients in France. The objective was a large survey of pneumococcal vaccination coverage (PVC) by general practitioners (GPs) in these patients in France. Diagnosis and treatment forms were extracted from the database of 2000 GPs. The GPs and population panels were representative of the metropolitan populations. The primary endpoint was the comparison of PVC in the adult patients diagnosed with COPD, CHF, DM, or HIV infection during the study (April 2013-April 2017) and the control (March 2012-March 2013) periods. Of the 17,865 and 4,690 patients identified, 756 (4%) and 267 (6%) were vaccinated, respectively. During the study period, the PVC was significantly higher (35/282, 12%) in HIV-infected patients and lower in patients with DM (95/5994, 2%) than in other patients. Even though French pneumococcal vaccine recommendations in adults were updated in 2013, the PVC did not increase according to the years of the study period and slightly increased according to time after diagnosis. S. pneumoniae is responsible only for some CAP and meningitis, and incomplete protection by vaccine, hesitancy from practitioners and patients, and the moving schedule of vaccination could explain the results. New tools and/or strategies must be implemented to increase PVC in France. Abbreviations: CAP: community-acquired pneumonia; COPD: chronic obstructive pulmonary diseases; CHF: congestive heart failure; DM: diabetes mellitus; IPD: invasive pneumococcal disease; HIV: human immunodeficiency virus; PVC: pneumococcal vaccination coverage; PCV7: 7-valent pneumococcal conjugate vaccine; PCV13: 13-valent pneumococcal conjugate vaccine; PPSV23: 23-valent pneumococcal polysaccharide vaccine; GPs: general practitioners; CLM: Cegedim Logiciels Médicaux; MLM: monLogicielMedical; ICD-10: International Classification of Diseases; CNIL: Commission nationale de l'informatique et des libertés; HPV: human papillomavirus; HBV: hepatitis B virus.

An expanding delivery model helps clinicians access the literature.

One of the biggest challenges clinicians face is keeping abreast of new information that affects the evaluation and treatment of their patients. The Journal of Orthopaedic & Sports Physical Therapy (JOSPT) was created in 1979 with this mandate in mind, using the established technology of the day: print on paper. A recent survey of JOSPT's readers confirms that the print version of the Journal remains valuable as a means of delivering this critical information. Yet the same survey demonstrates that the electronic distribution of searchable Journal articles, along with supplemental information such as videos and downloadable slides, is gaining increased attention and use. The website has become a cost- and time-effective and efficient means of acquiring this knowledge, regardless of the reader's location. This editorial provides an overview of some of the features JOSPT offers online.

Gefitinib-phenytoin interaction is not correlated with the C-erythromycin breath test in healthy male volunteers.

AIMS: We aimed to describe the pharmacokinetic interaction between phenytoin, a potent CYP3A4 and P-glycoprotein (P-gp) (ABCB1) inducer, and gefitinib, a CYP3A4, CYP2D6 and P-gp substrate. METHODS: An open-label, randomized, two-phase crossover study was conducted. Eighteen healthy male volunteers (nine homozygous CC and nine homozygous TT as determined by their ABCB1 C3435T polymorphism in exon 26) received a single oral dose of 250 mg gefitinib alone or after 5 days treatment with phenytoin (5 mg kg(-1) daily). Gefitinib plasma concentrations were determined by high-performance liquid chromatography. Hepatic CYP3A4 activity was evaluated by the (14)C-erythromycin breath test (ERMBT) and the ABCB1 and CYP2D6 genetic polymorphisms were determined by the TaqMan allelic discrimination assay and long polymerase chain reaction, respectively. RESULTS: Following treatment with phenytoin, mean gefitinib C(max) and AUC(0-infinity) decreased by 26 +/- 44% [95% confidence interval (CI) for the difference 5-48%, P= 0.005] and 47 +/- 26% (95% CI for the difference 34-60%, P= 0.001), respectively, and apparent oral clearance increased by 126 +/- 93% (95% CI for the difference 80-172%, P= 0.004). Concomitantly, phenytoin increased the mean ERMBT by 91 +/- 44% (95% CI 75-105%, P < 0.001) from baseline, but the extent of liver CYP3A4 induction was not correlated to the extent of interaction. Furthermore, this interaction was independent of ABCB1 genetic polymorphism. The CYP2D6 genotype was slightly but significantly related to gefitinib clearance (P= 0.04) during the control phase. CONCLUSIONS: The significant interaction between gefitinib and phenytoin was not correlated with the erythromycin breath test and was independent of ABCB1 polymorphism, but may involve presystemic CYP3A-mediated intestinal first-pass.

Déjà vu!

Interim Editor-in-Chief Guy G. Simoneau reflects on the Journal and its growth over the past 18 months. J Orthop Sports Phys Ther 2019;49(6):366. doi:10.2519/jospt.2019.0103.

Effects of seven potential probiotic strains on specific immune responses in healthy adults: a double-blind, randomized, controlled trial.

This pilot study investigated the immunomodulatory properties of seven probiotic strains. Eighty-three healthy volunteers aged 18-62 years consumed 2 x 10(10) CFU of bacteria or a placebo (maltodextrin) over 3 weeks (D0-D21). Subjects received an oral cholera vaccine at D7 and at D14; blood and saliva samples were collected at D0, D21 and D28. Serum samples were analyzed for specific IgA, IgG and IgM, and saliva samples were analyzed for specific IgA only, by ELISA. Statistical analyses were based on Wilcoxon's signed-rank test (intragroup analyses) and exact median t-test (intergroup analyses). Salivary analysis showed no difference in specific IgA concentrations between groups. Serum analysis indicated an effect of some of the tested strains on specific humoral responses. Between D0 and D21, IgG increased in two probiotic groups, for example, Bifidobacterium lactis Bl-04 and Lactobacillus acidophilus La-14, compared with controls (P=0.01). Trends toward significant changes in immunoglobulin serum concentrations compared with controls (P<0.1) were found for six out of the seven probiotic strains. In conclusion, some strains of probiotics demonstrated a faster immune response measured with serum immunoglobulin indicators, especially IgG, although overall vaccination was not influenced. Specific strains of probiotics may thus act as adjuvants to the humoral immune response following oral vaccination.

JOSPT's partnerships and enhancements for 2008.

Continued advances in communication technologies have made publishing an increasingly dynamic venture, offering authors and editors the ability to reach and interact with readers around the world in exciting and enlightening ways. Today's publications share information more quickly through diverse and sophisticated means. The new international partnerships and recent print and online enhancements described in this editorial reflect JOSPT's response to the technological possibilities now within our grasp. We believe that, ultimately, our expanding global audience and additional features will provide the profession as a whole with a better Journal.

The value of attending national and international conferences.

All physical therapists (academicians, researchers, and especially clinicians) are encouraged to take greater advantages of national and international conferences. While much can be learned by attending weekend courses with a specific clinical focus, national and international scientific meetings provide truly unique opportunities to learn about physical therapy practice from a perspective that no single weekend course can match.J Orthop Sports Phys Ther. 2008;38(9):527-528. doi:10.2519/jospt.2008.0111.

Who would you like to be when you grow up?

In February 2005, the Annals of Internal Medicine, a highly respected journal, published a systematic review of 59 manuscripts covering a total of 62 samples that reported on the relationship between medical knowledge/healthcare quality and years in practice/physician age. The implication of the data presented is that throughout their careers, physicians fail to upgrade their knowledge to keep pace with new information. I strongly believe that an important-if not the most important-component of continuing education relevant to clinical practice is accessing and reading the literature of this profession and related disciplines.
