One-year follow-up of immediate postpartum contraceptive implant insertion in adolescents.

PURPOSE: Our study aimed to evaluate the acceptability, adverse effects and continuation rates among adolescents who accepted the etonogestrel (ENG) subdermal implant and compared to adolescents who chose other methods during the immediate postpartum period before hospital discharge, with one year follow-up up. MATERIALS AND METHODS: We conducted a cohort non-randomised study at the Women's Hospital, University of Campinas. All women up to 19 years of age, who gave birth at the hospital between July 2019 and April 2020, were invited to participate and were offered the ENG-implant or the routine contraceptive methods. They were followed for one year postpartum. RESULTS: We included 100 teenagers and 72 accepted the ENG-implant. Students are more likely to accept the ENG-implant than non-students (PR: 1.25 [95%CI 0.99-1.59]). Up to one year of follow-up, survival analysis showed that the time of adherence to the method was longer for the ENG-implant users (p = 0.0049). More than 90% of the adolescents were satisfied with the implant; however, five requested early removal due to menstrual irregularity and local discomfort. CONCLUSION: Provision ENG-implant for adolescents in the immediate postpartum demonstrated high acceptance and ensured effective contraception. After one year, most of them were satisfied, with a high continuation rate and without unplanned pregnancies.

Standard reference values for the shock index during pregnancy.

OBJECTIVE: To assess variation in the shock index (SI; heart rate divided by systolic blood pressure) during pregnancy. METHODS: In a retrospective cohort study, data were assessed from the medical records of women with low-risk pregnancies who attended a primary healthcare unit for prenatal care in Campinas, Brazil, between January 2012 and December 2013. The means, standard deviations, and percentiles of SI values were calculated for different pregnancy lengths, stratified by body mass index (BMI) and maternal age. RESULTS: In total, 192 pregnant women with 1097 measurements were included. The mean SI values ranged from 0.756 ± 0.127 at 12 weeks or fewer to 0.831 ± 0.144 at 28-32 weeks. There was an increase in values in the second trimester and beginning of the third, followed by a decrease at term. The percentile distribution ranged from 0.522 (2.5th percentile) to 1.190 (97.5th percentile). SI values showed a trend toward lower values with increasing BMI. Regression analysis showed that BMI was the factor that most influenced the data. CONCLUSION: Reference ranges were established for SI values, which showed small variations throughout pregnancy and slightly higher values than the general population.

Longitudinal reference intervals for Doppler velocimetric parameters of the fetal renal artery correlated with amniotic fluid index among low-risk pregnancies.

OBJECTIVE: To establish longitudinal reference intervals for pulsatility index (PI) and systolic velocity (SV) of the fetal renal artery, and to evaluate their correlation with the amniotic fluid index (AFI). METHODS: A prospective longitudinal study was conducted among women with low-risk pregnancies who attended outpatient clinics at the University of Campinas Medical School, Brazil, at 16-19 weeks of pregnancy between April 1, 2008, and March 31, 2010. Doppler velocimetric measurements of the fetal renal artery and assessments of the AFI were undertaken at 4-week intervals to 36 weeks, and every 2 weeks thereafter until delivery. RESULTS: A total of 63 women were enrolled. The PI of the fetal renal artery showed little variation during pregnancy, whereas SV values increased to 36-37 weeks of pregnancy and decreased thereafter. No correlations were found between the AFI and the fetal renal artery Doppler velocimetric parameters (P>0.05 for all). The intraclass correlation coefficients for intra-observer and inter-observer variability indicated good reproducibility of SV, but the reproducibility of PI was lower. CONCLUSIONS: The AFI did not correlate with fetal renal artery Doppler velocimetric measures among low-risk pregnancies. However, investigations are needed among high-risk pregnancies.

Reference values for Doppler velocimetry of the ophthalmic and central retinal arteries in low-risk pregnancy.

OBJECTIVE: To establish reference values for Doppler velocimetry of the ophthalmic artery (OA) and the central retinal artery (CRA) in low-risk pregnancy. METHOD: Between January 2008 and March 2009, 63 low-risk pregnant women underwent an ultrasound scan every 2 weeks at the Women's Hospital, Campinas, Brazil, to determine the resistance index (RI), pulsatility index (PI), and peak systolic velocity of both arteries, in addition to the flow velocity of the second peak and peak ratio (PR) of the OA. For analysis, linear regression was used with mixed models for longitudinal data, coefficient of determination, and estimates of the 5th and 95th percentiles for each parameter at each gestational age. Intra- and inter-observer variability was evaluated via the intraclass correlation coefficient. RESULTS: There was a trend of a reduction with gestational age in PI and RI of the OA, and PI of the CRA, but not in PR of the OA; and the respective reference values were established. Intra- and inter-observer variability was considered satisfactory. CONCLUSION: Unilateral assessment of the orbital Doppler velocimetry is feasible. Establishment of reference values showed a negative correlation between gestational age and PI and RI of the OA, and PI of the CRA. The method demonstrated satisfactory reproducibility.

Factors associated with the prevalence of periodontal disease in low-risk pregnant women.

OBJECTIVE: To evaluate the prevalence of periodontal disease (PD) among Brazilian low-risk pregnant women and its association with sociodemographic factors, habits and oral hygiene. METHOD: This cross-sectional study included 334 low-risk pregnant women divided in groups with or without PD. Indexes of plaque and gingival bleeding on probing, probing pocket depth, clinical attachment level and gingival recession were evaluated at one periodontal examination below 32 weeks of gestation. Independent variables were: age, race/color, schooling, marital status, parity, gestational age, smoking habit, alcohol and drugs consumption, use of medication, presence of any systemic diseases and BMI (body mass index). Statistical analyses provided prevalence ratios and their respective 95%CI and also a multivariate analysis. RESULTS: The prevalence of PD was 47% and significantly associated with higher gestational age (PR 1.40; 1.01-1.94 for 17-24 weeks and PR 1.52; 1.10-2.08 for 25-32 weeks), maternal age 25-29 years, obesity (PR 1.65; 1.02-2.68) and the presence of gingival bleeding on probing (OR(adj) 2.01, 95%CI 1.41-2.88). Poor oral hygiene was associated with PD by the mean values of plaque and bleeding on probing indexes significantly greater in PD group. CONCLUSIONS: The prevalence of PD is high and associated with gingival bleeding on probing, more advanced gestational age and obesity. A program of oral health care should be included in prenatal care for early pregnancy, especially for low-income populations.

Mother-to-child transmission of human immunodeficiency virus in aten years period.

OBJECTIVES: to evaluate mother-to-child transmission (MTCT) rates and related factors in HIV-infected pregnant women from a tertiary hospital between 2000 and 2009. SUBJECTS AND METHOD: cohort of 452 HIV-infected pregnant women and their newborns. Data was collected from recorded files and undiagnosed children were enrolled for investigation. STATISTICAL ANALYSIS: qui-square test, Fisher exact test, Student t test, Mann-Whitney test, ANOVA, risk ratio and confidence intervals. RESULTS: MTCT occurred in 3.74%. The study population displayed a mean age of 27 years; 86.5% were found to have acquired HIV through sexual contact; 55% were aware of the diagnosis prior to the pregnancy; 62% were not using HAART. Mean CD4 cell-count was 474 cells/ml and 70.3% had undetectable viral loads in the third trimester. HAART included nevirapine in 35% of cases and protease inhibitors in 55%; Zidovudine monotherapy was used in 7.3%. Mean gestational age at delivery was 37.2 weeks and in 92% by caesarian section; 97.2% received intravenous zidovudine. Use of AZT to newborn occurred in 100% of them. Factors identified as associated to MTCT were: low CD4 cell counts, elevated viral loads, maternal AIDS, shorter periods receiving HAART, other conditions (anemia, IUGR (intra uterine growth restriction), oligohydramnium), coinfecctions (CMV and toxoplasmosis) and the occurrence of labor. Use of HAART for longer periods, caesarian and oral zidovudine for the newborns were associated with a decreased risk. Poor adhesion to treatment was present in 13 of the 15 cases of transmission; in 7, coinfecctions were diagnosed (CMV and toxoplasmosis). CONCLUSION: Use of HAART and caesarian delivery are protective factors for mother-to-child transmission of HIV. Maternal coinfecctions and other conditions were risk factors for MTCT.

Perinatal outcomes associated with low birth weight in a historical cohort.

OBJECTIVE: To identify perinatal outcomes associated with low birth weight (LBW). METHODS: A retrospective cohort study in a tertiary maternity hospital. Analysis of the database on 43,499 liveborn infants delivered between 1986 and 2004 with low (n = 6,477) and normal (n = 37,467) birth weight. Outcomes associated with LBW were identified through crude and adjusted risk ratio (RR) and 95%CI with bivariate and multivariate analysis. The main outcomes were: onset of labor, mode of delivery, indication for cesarean section; amniotic fluid, fetal heart rate pattern, Apgar score, somatic gestational age, gender and congenital malformation. RESULTS: LBW infants showed more frequently signs of perinatal compromise such as abnormal amniotic fluid volume (especially olygohydramnios), nonreassuring patterns of fetal heart rate, malformation, lower Apgar scores and lower gestational age at birth. They were associated with a greater risk of labor induction and cesarean delivery, but lower risk of forceps. CONCLUSION: There was a clear association between LBW and unfavorable perinatal outcomes.

Quality of life and menopausal and sexual symptoms in gynecologic cancer survivors: a cohort study.

OBJECTIVES: The aims of this study were to investigate the frequency of menopausal and sexual symptoms and the proportion of sexually active women and to assess and identify quality of life (QOL) predictors in gynecologic cancer survivors. METHODS: A prospective case series following a cohort of women under radiation therapy was conducted, including 107 women (aged 21-75 y) with gynecologic cancer (cervical or endometrial cancer) who underwent pelvic radiotherapy in the Radiotherapy Division of the Women's Integral Healthcare Center at the Universidade Estadual de Campinas. Adverse effects of radiotherapy were evaluated using the Common Terminology Criteria Adverse Event Scale. QOL was measured using the abbreviated version of the World Health Organization's Quality of Life instrument before radiotherapy (T0) and at 4 months (T1), 1 year (T2), and 3 years (T3) after radiotherapy. QOL scores were assessed over time using the Wilcoxon signed-rank test. Multiple linear regression analysis was used to identify QOL predictors. RESULTS: A decrease in the frequency of vaginal dryness (26.7% in T0 vs 8.3% in T3; P < 0.01) and an increase in the proportion of sexually active women (21.5% in T0 vs 44.2% in T3; P < 0.01) were observed. A significant increase in QOL scores was observed in the psychological domain and general health and overall QOL. Dyspareunia negatively affected the physical (P < 0.01), psychological (P < 0.01), and social relationship domains (P < 0.01); overall QOL (P = 0.01); and general health (P = 0.04). Family income was positively related to environment domain (P < 0.01), overall QOL (P = 0.04), and general health (P < 0.01). CONCLUSIONS: Data derived from this study indicated that gynecologic cancer survivors had a lower frequency of vaginal dryness and a higher proportion of these women were sexually active 3 years after completion of radiotherapy. Furthermore, QOL improved and dyspareunia negatively affected various QOL dimensions.

Knowledge about osteoporosis in postmenopausal women undergoing antiresorptive treatment.

UNLABELLED: A good understanding and knowledge of osteoporosis is a prerequisite for the success of preventive measures as well as treatment adherence. OBJECTIVE: To assess knowledge about osteoporosis in postmenopausal women with osteoporosis or osteopenia undergoing antiresorptive treatment. SUBJECTS AND METHODS: A cross-sectional study was based on a sample of 232 postmenopausal women with osteopenia or osteoporosis diagnosed by bone density studies and seen at the Menopause Outpatient Clinic at Caism/Unicamp. Women's knowledge of osteoporosis was assessed by means of the OPQ (Osteoporosis questionnaire), a 20-item questionnaire about osteoporosis in areas of general information, risk factors, consequences and treatment. RESULTS: The average age of the women was 61.6 years (±8.2 years) and the average time since menopause was 16.8 years. The average knowledge score obtained by the OPQ was 3.78. The average score for correct answers was 9.8 points, while the average score for incorrect answers was 6 points and 'don't know' answers was 4.1 points. Bivariate analysis showed the variables most closely associated with greater knowledge: education (p<0.01), reading (p<0.02), socioeconomic status (p<0.03), means of acquiring osteoporosis medication (p<0.02), and absence of comorbidities (p<0.04). On multiple regression analysis, the factors which remained associated with better knowledge were higher education, higher socioeconomic status scores and absence of comorbidities. CONCLUSION: Knowledge of osteoporosis in postmenopausal women diagnosed with the disease was limited. Level of education was a strong predictor of knowledge.

Periodontal disease and some adverse perinatal outcomes in a cohort of low risk pregnant women.

OBJECTIVE: To evaluate the association of periodontal disease (PD) in pregnancy with some adverse perinatal outcomes. METHOD: This cohort study included 327 pregnant women divided in groups with or without PD. Indexes of plaque and gingival bleeding on probing, probing pocket depth, clinical attachment level and gingival recession were evaluated at one periodontal examination below 32 weeks of gestation. The rates of preterm birth (PTB), low birth weight (LBW), small for gestational age (SGA) neonates and prelabor rupture of membranes (PROM) were evaluated using Risk Ratios (95%CI) and Population Attributable Risk Fractions. RESULTS: PD was associated with a higher risk of PTB (RRadj. 3.47 95%CI 1.62-7.43), LBW (RRadj. 2.93 95%CI 1.36-6.34) and PROM (RRadj. 2.48 95%CI 1.35-4.56), but not with SGA neonates (RR 2.38 95%CI 0.93 - 6.10). CONCLUSIONS: PD was a risk factor for PT, LBW and PROM among Brazilian low risk pregnant women.

Accuracy of white blood cell count, C-reactive protein, interleukin-6 and tumor necrosis factor alpha for diagnosing late neonatal sepsis.

OBJECTIVE: To evaluate the diagnostic value for late neonatal sepsis of white blood cell count (WBC) and assays for C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha), in isolation and in conjunction. METHODS: This was a diagnostic test validation study. Chemiluminescence was used to assay CRP, IL-6 and TNF-alpha at the time of clinical suspicion and again after 24 and 48 hours, whereas the WBC was performed only once, at the time of suspicion. Patients were classified into three groups based on clinical progress and culture results: confirmed sepsis (CS), probable sepsis (PS), and not infected (NI). Statistical analysis was performed using the Wilcoxon and chi-square tests and Friedman analysis of variance; cutoffs were defined by plotting receiver operator characteristic curves. RESULTS: The total study sample comprised 82 children, 42 of whom were classed as CS, 16 as PS and 24 as NI. At all three test times, the medians for CRP and IL-6 were significantly more elevated in the CS and PS groups, while the medians for TNF-alpha were abnormal only in the CS group. The CRP test had elevated indices of diagnostic utility at all three test times, better accuracy than the WBC and similar accuracy to the first IL-6 and TNF-alpha assays. There was no statistical difference between the cytokines, nor between them and the WBC. Combining tests did not increase diagnostic power, with the exception of the combination of WBC with CRP2 and when the sequential CRP assays were combined. CONCLUSIONS: Both CRP and WBC were useful for the diagnosis of late neonatal sepsis and comparable with IL-6 and TNF-alpha. Accuracy increased when CRP and WBC were combined and when sequential CRP assay results were used.

Acurácia diagnóstica do leucograma, proteína C-reativa, interleucina-6 e fator de necrose tumoral-alfa na sepse neonatal tardia / Accuracy of white blood cell count, C-reactive protein, interleukin-6 and tumor necrosis factor alpha for diagnosing late neonatal sepsis

OBJETIVO: Avaliar o valor do leucograma, proteína C-reativa (PCR), interleucina-6 (IL-6) e do fator de necrose tumoral-alfa (TNF-α), isoladamente e em conjunto, na detecção da sepse neonatal tardia. MÉTODOS: Estudo de validação diagnóstica. A PCR, IL-6 e TNF-α foram dosados por quimioluminescência à suspeita clínica, 24 e 48 horas depois, e o leucograma unicamente à suspeita. De acordo com evolução clínica e resultados de culturas, três grupos foram definidos: sepse comprovada (SC), sepse provável (SP) e não infectados (NI). Os testes estatísticos utilizados foram os de Wilcoxon, qui-quadrado e análise de variância de Friedman e os limites de corte foram obtidos pela construção da curva ROC. RESULTADOS: Estudaram-se 82 crianças, sendo 42 no grupo SC, 16 no SP e 24 NI. Nos três momentos, as medianas da PCR e da IL-6 mostraram-se significativamente mais elevadas nos grupos SC e SP, e as do TNF-α alteraram-se apenas no grupo SC. Os índices diagnósticos da PCR foram elevados nos três momentos e com acurácia superior a do leucograma e semelhante a da IL-6 e a do TNF-α em suas primeiras medidas. Entre as citocinas, não houve diferença estatística entre elas, nem em relação ao leucograma. A associação dos testes não aumentou a capacidade diagnóstica, exceto na combinação entre leucograma e PCR2 e na dosagem seriada de PCR. CONCLUSÕES: A PCR e o leucograma mostram-se úteis no diagnóstico de sepse neonatal tardia e comparáveis à IL-6 e ao TNF-α. A acurácia aumentou com a associação PCR-leucograma e a dosagem seriada da PCR.

The associations between inter-pregnancy interval and maternal and neonatal outcomes in Brazil.

OBJECTIVES: Global estimates of maternal and perinatal mortality have remained unchanged over the past 20 years, and strategies are being sought to decrease the occurrence of maternal and perinatal death. The objective of this study was to evaluate the association between inter-pregnancy interval and the occurrence of adverse maternal and perinatal outcomes. DESIGN AND SETTING: Cross-sectional study of the obstetrical and perinatal records in an intra-hospital obstetrics database between 1986 and 2000 at a tertiary maternity hospital in Brazil. PARTICIPANTS: A total of 14,930 records of parous women who delivered singleton infants. MAIN OUTCOME MEASURES: Crude and adjusted odds ratio estimates of gestational outcome according to inter-pregnancy intervals. RESULTS: During the period of the study, 34.6% of records referred to women with an inter-pregnancy interval <18 months. After the adjustment performed for 11 confounding factors and assuming an inter-pregnancy interval of 18-23 months as reference, short intervals (<6 months) were observed to be associated with a greater risk of low birth weight (odds ratio: 1.74; 95% confidence interval: 1.18-2.55), and preterm birth (1.56; 1.01-2.46). On the other hand, long intervals were significantly associated with fewer C-sections (0.69; 0.56-0.82), and a greater risk of premature rupture of membranes (PROM) (1.57; 1.20-2.06) and low birth weight (1.46; 1.03-2.06). CONCLUSIONS: Short inter-pregnancy intervals are associated with a higher risk of low birth weight and preterm birth, while long intervals are associated with a higher risk of PROM, low birth weight and a lower risk of C-section.

Chronic periodontitis and pre-term labour in Brazilian pregnant women: an association to be analysed.

AIM: To investigate the association between chronic periodontitis (CP) and pre-maturity in a group of Brazilian pregnant women from the State of São Paulo. MATERIALS AND METHODS: One hundred and twenty-four women were investigated consecutively in a cross-sectional study, between December 2003 and May 2005. Sixty-eight women had pre-term labour (PTL) and 56 had term labour. A periodontal examination was carried out to identify the presence of CP. Statistical analysis used the Fisher's exact test or chi(2) for the discrete variables and the Mann-Whitney test for the non-parametric variables. Odds ratio (OR) was calculated with a 95% confidence interval (CI), to evaluate the relation between CP and pre-maturity. RESULTS: Periodontal indicators, such as clinical attachment loss (p<0.0001) and bleeding on probing (p=0.012), were observed more in the PTL group. The presence of CP increased the risk for PTL (OR: 4.7, 95% CI: 1.9-11.9), pre-term birth (PTB; OR: 4.9, 95% CI: 1.9-12.8) and low birth weight (<2500 g; OR: 4.2, 95% CI: 1.3-13.3). The pregnant women with PTL presented low levels of schooling (p=0.029) and the lowest number of pre-natal appointments (p=0.0001) when compared with those with term labour. CONCLUSION: CP is strongly associated with PTL, PTB and low birth weight in a group of Brazilian pregnant women. These data point to the necessity of regularly investigating CP during pregnancy.

Management of stress urinary incontinence with surface electromyography-assisted biofeedback in women of reproductive age.

BACKGROUND AND PURPOSE: Although surgery has been widely accepted as the treatment of choice for stress urinary incontinence (SUI), there has recently been an increased interest in the conservative management of this condition. The aims of this study were to test the ability of a biofeedback-assisted pelvic-floor muscle exercise (PFME) program to affect symptoms of SUI in premenopausal women and to evaluate a training program that might lead to successful outcomes in a relatively limited number of sessions. SUBJECTS: Twenty-six women with SUI were treated with PFME with surface electromyography (sEMG)-assisted biofeedback. All participants were of reproductive age and were treated individually for 12 sessions. METHODS: results were evaluated with a 7-day voiding diary, a 1-hour pad test, pelvic-floor muscle strength measurements, sEMG amplitudes, a leakage index, and a quality-of-life questionnaire. These variables were compared before and after the intervention. RESULTS: The frequency of urine loss, the occurrence of nocturia, and the number of pads required decreased significantly after the intervention. Objective cure was found in 61.5% of women. There was a significant improvement in the quality of life, in pelvic-floor muscle strength, and in the sEMG amplitudes of all contractions throughout the intervention. DISCUSSION AND CONCLUSION: A relatively short-term intervention of PFME with sEMG-assisted biofeedback appeared to be helpful in relieving symptoms of SUI in premenopausal women and represents a reasonable conservative management option.

Human papillomavirus (HPV) infections as risk factors for cytological and histological abnormalities in baseline PAP smear-negative women followed-up for 2 years in the LAMS study.

OBJECTIVE: To assess the role of HPV as determinant of the incident cytological abnormalities (SIL) and cervical lesions (CIN) during a 24-month follow-up of baseline PAP smear-negative subgroup of women included in the Latin American Screening study (LAMS). STUDY DESIGN: A group of 365 women with normal Pap smear and negative or positive high-risk Hybrid Capture II test were prospectively followed-up for 24 months at Campinas and São Paulo (Brazil). The incidence rate (IR) and risk ratio (RR and 95% CI) of developing cytological or histological abnormality during the follow-up was calculated for HPV-negative and HPV-positive women. RESULTS: During the 12-month follow-up, women HPV-positive at baseline had developed a significantly higher rate of incident LSIL (IR=3.5%, RR=1.4; 95% CI 1.1-1.7) and HSIL (IR=0.7%, RR=1.5; 95% CI 1.4-1.7) abnormality. For HSIL, the IR increased to 2.1% and the RR increased to 1.7 (95% CI 1.5-1.9) among those followed for 24 months. Similarly, women with positive HPV tests were at a higher risk of developing CIN 2-3 (IR=2.6%, RR=1.5; 95% CI 1.4-1.6) during the first 12 months of follow-up, and for those followed for 24 months, this RR increased further to 1.7 (95% CI 1.5-1.9) although the IR was 0.7%. CONCLUSIONS: Oncogenic HPV infections comprise a significant risk factor for incident cervical abnormalities, and HPV test is a useful adjunct to cytology in detecting the high-risk patients among baseline PAP smear-negative women.

The attitude of gynecologists in São Paulo, Brazil 3 years after the Women's Health Initiative study.

OBJECTIVE: The objective of this study was to evaluate gynecologists' knowledge of the WHI study, and its repercussions on their attitudes and practice 3 years after publication. DESIGN: A self-administered, anonymous questionnaire containing 19 questions was sent to 6000 gynecologists, members of the São Paulo Society of Obstetrics and Gynecology. RESULTS: The response rate was 24.2% (1453 completed questionnaires) with a sample error of 2.23% and confidence level of 95%. Although 95.9% of the respondents were aware of the WHI study, only 24.4% knew of all the other studies mentioned (HERS I, HERS II and Million Women Study). Although 84.6% stated that the results of the WHI study could not be extrapolated to other forms of HT, 23.1% and 25.2%, respectively, stopped prescribing CEE or MPA, 63.7% decreased the dose, 55.2% opted for drugs such as bisphosphonates, tibolone and SERMS, and 46.3% began to prescribe tranquilizers, isoflavone and other natural medications. Moreover, 59.2% agreed that HT should be used for only 4-5 years. Prescriptions decreased significantly for all indications (p<0.0001). The principal reason for physicians to discontinue HT in a patient was increased risk of breast cancer (62.3%), whereas, according to the physicians, the most important factor for the patients was fear of HT (80.3%). CONCLUSION: A high percentage of gynecologists in this study knew of the WHI study and followed its recommendations concerning cardiovascular prevention; consequently they changed their management of the treatment of postmenopausal women by restricting indications for HT and decreasing its duration of use and dose.
