Integrating prenatal-postnatal smoking interventions into usual care in a health maintenance organization.

Consistent with the increasing national emphasis on providing health promotion in clinical care settings, Stop Smoking for OuR Kids (STORK), a research-derived, prenatal-postnatal smoking cessation intervention, was implemented throughout prenatal clinics, inpatient postpartum services, and pediatric clinics of Kaiser Permanente Northwest. Process data collected during the project rollout and maintenance to monitor the clinical practices of clinicians and staff members, patient responses to the intervention, and penetration of the intervention into the health maintenance organization priority population of prenatal smokers high-lighted barriers to intervention delivery. These barriers fell into three categories related to the smoking intervention design, clinicians and staff members, and the organization. By monitoring the intervention implementation process, such problems were identified early. This allowed for implementing strategies to overcome many of these barriers and to assess their effectiveness. Keys to implementation success included simplifying the intervention activities, considering stakeholder needs, and providing tangible organizational resources and goals.

Changing nursing practice through research utilization: consistent support for breastfeeding mothers.

This research utilization project was designed to increase staff nurse support for four early postpartum breastfeeding practices: initiation in the delivery room, high frequency feedings, unlimited suckling time, and no supplementation. Research links these practices with lower neonatal bilirubin values and an earlier onset of lactation. An organizational approach to research utilization was taken to encourage nurses to support mothers in the desired breastfeeding practices. A before and after design was used to evaluate the extent to which the intended patient outcomes were achieved with the practice changes. The percent of infants having bilirubin tests decreased significantly. No significant differences were observed in mean bilirubin levels, incidence of hyperbilirubinemia, or lactation onset. The project promoted state-of-the-science nursing care and helped our nurses become more adept in using research to guide practice.

The influence of health care on contraceptive acceptance in rural Mexico.

This paper offers two types of evidence in support of the idea that family planning services are most expediently provided as an integral part of the health and medical organization for maternity care. First, prenatal care and medical attention at delivery are found to be closely associated with postpartum contraceptive acceptance in a 1981 survey of family planning in rural Mexico. Second, interviews of a sample of doctors, nurses, and auxiliaries who provide maternal health services to the rural population reveal that these practitioners favor long birth intervals and small completed families, that they recommend the use of modern contraceptive methods including female sterilization, and that those in the employ of public institutions are motivated to recruit acceptors of these methods. The main impediment to contraceptive acceptance in this context is believed to be fear of side effects and permanent health consequences rather than the desire for additional children.

A reappraisal of the need for autologous blood donation in the obstetric patient.

There has been recent interest in autologous blood donation in obstetric patients, but little attention has been paid to whether such programs are needed or whether the patients that will require transfusion can be accurately predicted. At the University of California San Diego Medical Center from July 1 to Dec. 31, 1988, there were 2265 deliveries; 13 women (0.57%) received blood transfusions. Traditionally accepted risk factors were identified in 251 patients, with only four (1.6%) requiring transfusion. Among the 150 patients delivered by repeat cesarean section, only one (0.7%) required blood. one of 27 (3.7%) multiple gestations, two of eight (25%) patients with placenta previa, and none of the 66 grandmultiparous women had transfusions. These data suggest that autologous blood donation may not be beneficial or cost effective when the low frequency of blood transfusions in this high-risk obstetric population and the difficulty in accurately predicting those likely to require transfusions are considered.

Two evaluations of combined mother-infant versus separate postnatal nursing care.

Combined mother-infant postnatal nursing care was compared with traditional, separate postpartum and newborn care in two studies. In Study I, self-administered questionnaires were completed by 408 mothers and 63 staff nurses. Data were collected both before and after mother-infant care was implemented. Benefits of the new system included increased maternal competence and satisfaction with parent education, parent-infant contact, and the nurse-client relationship, increased staff satisfaction, with no increase in operational cost. There were no breastfeeding differences, but ways to improve duration were implied by reasons for stopping. These findings were replicated in a separate setting with similar sample sizes. However, in the latter case, low staff ratios appeared to limit the benefits of mother-infant care to multiparas rather than primiparas.

Incidence of premature estrus in lactating dairy cows and conception rates to standing estrus or fixed-time inseminations after synchronization using GnRH and PGF(2alpha).

Fixed-time AI (TAI) after GnRH-PGF(2alpha)-GnRH treatment is a method to achieve pregnancies in dairy herds without estrous detection. However, cows that fail to respond to the initial GnRH may have compromised TAI conception rates due to asynchronous ovarian response. This study documented the percentage of GnRH-treated Holstein cows (n=345) in two herds that displayed estrus at an inopportune time for optimum TAI conception rate (< or =48h post-PGF(2alpha); premature estrus (PE)) and compared conception rates of two TAI protocols in cows that did not display PE. At biweekly herd health exams, cows diagnosed as not pregnant to a previous AI and cows >80 days postpartum with no AI were treated with 100 microg GnRH (day -7) and 25mg PGF(2alpha) (day 0). Cows detected in PE by twice-daily visual observation from day -7 to day 2 were bred by AI 8-12h later. Cows not detected in PE were randomly assigned by parity, body condition score, and postpartum interval to receive either: (1) 100microg GnRH at 48h after PGF(2alpha) and TAI 16 to 18h later (Ovsynch); or (2) TAI at 72h post-PGF(2alpha) and a concurrent 100 microg GnRH injection to those cows not detected in estrus between 48 and 72h post-PGF(2alpha) (modified Ovsynch (MOV)). All hormone injections were im. Twenty percent (68/345) of the cows were detected in estrus before 48 after PGF(2alpha), of which 5% (17/345) were detected in estrus before PGF(2alpha) (< or =day 0). Herd influenced the percentage of cows in the PE group (herd A versus herd B; 25% versus 14%; P<0.05). Conception rates were not affected by treatment (PE versus Ovsynch versus MOV; 32% (21/65) versus 30% (37/125) versus 32% (47/145); P>0.10). However, within MOV-treated cows, conception rates were greater (P<0.05) in cows detected in estrus (46% (23/50)) compared with cows not detected in estrus (25% (24/95)). In conclusion, 20% of GnRH-treated cows displayed PE and necessitates estrous detection during this period if maximal pregnancy rates are to be achieved. Although additional estrous detection is required compared to Ovsynch, reduced cow handling and hormone usage, efficient use of expensive semen through greater conception rates in cows detected in estrus, and comparable TAI conception rates, suggests the MOV protocol may be a cost effective alternative to Ovsynch in many dairy herd reproductive management programs.

Reducing maternal smoking and relapse: long-term evaluation of a pediatric intervention.

BACKGROUND: Pediatric well-care visits provide a clinical opportunity to counsel new mothers about their smoking and the deleterious effects of environmental tobacco smoke (ETS) on infant health. METHODS: Forty-nine Oregon pediatric offices enrolled 2,901 women who were currently smoking or had quit for pregnancy, using a brief survey at the newborn's first office visit. Randomly assigned offices provided advice and materials to mothers at each well-care visit during the first 6 months postpartum to promote quitting or relapse prevention. RESULTS: The intervention reduced smoking (5.9% vs 2.7%) and relapse (55% vs 45%) at 6-month follow-up, but logistic regression analysis at 12 months revealed no significant treatment effect. The intervention had a positive effect on secondary outcome variables, such as readiness to quit and attitude toward and knowledge of ETS. Multiple logistic regression analysis indicated that husband/partner smoking was the strongest predictor of maternal quitting or relapse. CONCLUSIONS: A pediatric office-based intervention can significantly affect smoking and relapse prevention for mothers of newborns, but the effect decreases with time. Consistent prompting of the provider to give brief advice and materials at well-care visits could provide a low-cost intervention to reduce infant ETS exposure.

Synchronizing estrus and(or) ovulation in beef cows after combinations of GnRH, norgestomet, and prostaglandin F2alpha with or without timed insemination.

Three experiments were conducted to induce estrus and(or) ovulation in 1,590 suckled beef cows at the beginning of a spring breeding season. In Exp. 1, 890 cows at three locations were allotted to three treatments: 1) GnRH on d -7 + prostaglandin F2alpha (PGF2alpha) on d 0 (Select Synch); 2) GnRH on d -7 + PGF2alpha on d 0 (first day of the breeding season) plus a norgestomet implant (NORG) between d -7 and 0 (Select Synch + NORG); or 3) two injections of PGF2alpha given 14 d apart (2xPGF2alpha). More (P < 0.05) cycling cows were detected to have been in estrus after both treatments that included GnRH, whereas, among noncycling cows, the addition of norgestomet further increased (P < 0.05) the proportion in estrus. Pregnancy rates were greater (P < 0.01) among noncycling cows after treatments that included GnRH. For cows that calved >60 d before the onset of the breeding season, conception rates were greater (P < 0.01) than those that calved < or =60 d regardless of treatment, whereas days postpartum had no effect on rates of detected estrus. When body condition scores were < or =4 compared with >4, rates of detected estrus (P < 0.05) and conception (P = 0.07) were increased. In Exp. 2, 164 cows were treated with the Select Synch + NORG treatment and were inseminated either after estrus or at 16 h after a second GnRH injection (given 48 h after PGF2alpha). Conception and pregnancy rates tended (P = 0.08) to be or were less (P < 0.05), respectively, for noncycling cows inseminated by appointment, but pregnancy rates exceeded 53% in both protocols. In Exp. 3, 536 cows at three locations were treated with the Select Synch protocol as in Exp. 1 and inseminated either: 1) after detected estrus (Select Synch); 2) at 54 h after PGF2alpha when a second GnRH injection also was administered (Cosynch); or 3) after detected estrus until 54 h, or in the absence of estrus, at 54 h plus a second GnRH injection (Select Synch + Cosynch). Conception rates were reduced (P < 0.01) in cows that were inseminated by appointment. An interaction of AI protocol and cycling status occurred (P = 0.05) for pregnancy rates with differing results for cycling and noncycling cows. Across experiments, variable proportions of cows at various locations (21 to 78%) were cycling before the breeding season. With the GnRH or GnRH + NORG treatments, ovulation was induced in some noncycling cows. Conception rates were normal and pregnancy rates were greater than those after a PGF2alpha program, particularly when inseminations occurred after detected estrus.

Evaluation of a new Swedish protocol for alloimmunization screening during pregnancy.

Screening protocols for alloimmunization during pregnancy usually make a difference between primi- and multigravidae as well as between Rh(D) negative and Rh(D) positive pregnant women. We have evaluated a new screening program including antibody tests at 25 and 35 gestational weeks only, for all, and regardless of Rh(D) group. During the time period 1983-89, 78,300 consecutive pregnancies were tested. Red cell antibody immunizations were detected in 287 (0.37%) pregnancies subdivided into fourteen different red cell IgG antibody specificities. Significant antibody titers (defined as IAT or enzyme titers > or = 8) were observed in 225 pregnancies, where 127 (56%) were previously unknown. A majority (63%) of the new immunizations occurred among the Rh(D) positive pregnant women. All newborns that needed phototherapy or exchange transfusion due to alloimmunization were recognized at the time of delivery. We conclude that antibody screening tests at 25 and 35 gestational weeks for both Rh(D) negative and positive pregnant women is sufficient, effective and a safe procedure for the fetus as well as for the mother.

Does parental breastfeeding knowledge increase breastfeeding rates?

OBJECTIVE: Although improving mothers' knowledge about breastfeeding can increase rates and duration of breastfeeding, little is known about the influence of fathers' knowledge. The purpose of this study was to assess the knowledge of mothers and fathers about breastfeeding before and after receiving postpartum advice and its relationship to the frequency of breastfeeding. METHODS: A clinical trial was performed with mothers and fathers of normal children born at the Hospital de Clínicas de Porto Alegre, Brazil, between July 1994 and March 1995. The study intervention consisted of postpartum advice supplied by means of a video film discussing basic topics of breastfeeding, an explanatory leaflet, and open discussion after viewing the video. The first 208 couples comprised the control group, the next 197 comprised experimental group 1, and the remaining 196 comprised experimental group 2. Immediately after delivery, mothers and fathers in the three groups answered a test on breastfeeding knowledge; they completed the same test at the end of the first month. All families received home visits at the end of the first, second, fourth, and sixth months, or until breastfeeding ceased. Logistic regression was used to evaluate the association between the mothers' and fathers' knowledge and frequency of breastfeeding. RESULTS: Postpartum advice increased the breastfeeding knowledge of mothers and fathers. The mothers with the highest level of knowledge had a 6.5 times higher chance of exclusively breastfeeding at the end of the third month, and 1.97 times higher chance of continuing breastfeeding to the end of the sixth month compared with other mothers. The fathers' knowledge also significantly influenced breastfeeding rates. The children whose fathers knew more had a 1.76 higher chance of being exclusively breastfed at the end of the first month, and 1.91 higher chance of receiving maternal milk at the end of the third month. CONCLUSION: A simple, inexpensive strategy can increase the level of breastfeeding knowledge of mothers and fathers and, consequently, have a positive impact on the frequency of breastfeeding.

The effect of long-term calcium supplementation on indices of iron, zinc and magnesium status in lactating Gambian women.

The effect of long-term supplementation with CaCO3 on indices of Fe, Zn and Mg status was investigated in a randomized, double-blind intervention study of sixty lactating Gambian women. The supplement contained 1000 mg Ca and was consumed between meals 5 d/week, for 1 year starting 1.5 weeks postpartum. Compliance was 100%. Plasma ferritin concentration, plasma Zn concentration and urinary Mg output were measured before, during and after supplementation at 1.5, 13, 52 and 78 weeks postpartum. No significant differences in mineral status were observed at any time between women in the supplement and placebo groups. Analysis of the longitudinal data series showed that plasma ferritin and Mg excretion were characteristic of the individual (P < 0.001). Within individuals, ferritin concentration was higher at 1.5 weeks postpartum than later in lactation (P = 0.002). Plasma Zn concentration was lower at 1.5 weeks postpartum than at other times (P < 0.001), an effect which disappeared after albumin correction. Low plasma concentrations of ferritin and Zn indicated that the Gambian women were at high risk of Fe and Zn deficiency. Measurements of alpha 1-antichymotrypsin suggested that the results were not confounded by acute-phase responses. The results of the present study indicate that 1000 mg Ca as CaCO3 given between meals does not deleteriously affect plasma ferritin and Zn concentrations or urinary Mg excretion in women who are at risk of Fe and Zn deficiency.

From the field: a maternal-child health nursing competence validation model.

This group of Vermont community health nurses from different agencies collaborated to develop a competence validation framework for maternal and child health nursing in the practice areas of perinatal client teaching, breastfeeding, and prenatal, postpartum, and newborn nursing care. The framework is based on the work of Benner, using the "competent" level of nursing practice, and delineates three parameters of competence: technical skills, interpersonal skills, and critical thinking skills. Learning resource materials, including newborn and maternal assessment guidelines, were developed for each competence area. The four competence validation tools were successfully tested for validity and reliability as well as efficiency and effectiveness by nurses in all 13 home health agencies and 12 public health district offices in Vermont. This system of competence validation is now used to support a consistently high quality of care for all recipients of Vermont's Healthy Babies, Kids, and Families services, and is available for use in other care settings.

Management of the dry cow in control of peripartum disease and mastitis.

The dry period has great implications on overall health and productivity in the subsequent lactation. Many anatomic, physiologic, and immunolgic changes are occurring for both the cow and the mammary gland during this time. These changes need to be understood and taken into consideration when assessing and implementing health management programs that involve this crucial time period. Specifically, nutritional and immunologic requirements of the individual cow need to be considered. The occurrence of many peripartum diseases is significantly influenced through nutritional and metabolic parameters that can be strongly influenced, controlled, and monitored in the dry period. From an udder-health perspective, the goal of the dry period can be met by recommending administration of DCT to all quarters of all cows at the end of lactation. As research continues to explore and define shortcomings of this approach and as scrutiny of the prophylactic use of antibiotics increases, however, novel approaches to preventing and eliminating IMI may become more readily available. These approaches offer new methods to improve upon and redefine what should be realistic goals of the dry period and afford an opportunity for continued improvement of udder health in today's dairy herds.

Internal medical residents' ability to diagnose and characterize major depression.

The purpose of this study was to assess medical residents' knowledge of symptom criteria and subtypes of major depressive episode and their accuracy in diagnosing major depressive disorders and classifying episode severity and subtype according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Thirty-five third-year internal medicine residents completed a self-administered, written instrument containing 2 open-ended questions and 21 hypothetical scenarios. The sensitivity for recognizing major depressive disorder was 64%, and the specificity was 69%. The sensitivity for classifying severity was 86% for mild, 66% for moderate, 71% for severe, and 66% for severe with psychosis. Misclassification of severity was most commonly to a less severe class. For scenarios with a diagnosable subtype of a major depressive disorder, the sensitivity for classification was 34% for atypical, 51% for catatonic, 74% for melancholic, 100% for postpartum, and 94% for seasonal depression. When asked to enumerate the criteria symptoms for depression, 80% or more of the residents listed sad mood, loss of interest, weight change, and sleep disturbances; 14 to 21 (40%-60%) listed thoughts of death and worthlessness; other criteria were listed by 7 to 11 (20%-31%). When asked to list the episode subtypes, none was listed by more than 3 (9%) residents, although 13 (37%) residents volunteered psychotic as a subtype. Residents frequently failed to recognize the presence or absence of major depressive disorder and often misclassified episode severity and subtype on scenarios. Few could spontaneously list the episode subtypes. Methods must be developed to improve the recognition and classification of major depressive episodes to better direct treatment.

Antepartum and early postpartum predictors of type 2 diabetes development in women with gestational diabetes mellitus.

OBJECTIVES: This study aimed at identifying ante-partum and early post-partum (one year) clinical and metabolic characteristics capable of predicting the future development of type 2 diabetes in pregnant women of Mediterranea area affected by gestational diabetes mellitus (GDM). MATERIAL AND METHODS: Seventy GDM patients were evaluated: mean age during pregnancy, plasma glucose levels under OGTT (100 gr. glucose), fasting, 1-h post-prandial plasma glucose levels, HbA(1c) at the third trimester, gestational week of GDM diagnosis, insulin therapy, and weight gain were all taken into consideration. Some maternal risk factors such as pre-pregnancy BMI, and maternal and fetal outcome of index pregnancy were also assessed. One year after delivery in the same patients, BMI, fasting and 1-h post-prandial plasma glucose, plasma glucose and insulinemia under OGTT (75 gr. glucose) were measured. We focused our attention on women who presented type 2 diabetes 5 years after pregnancy or IGT and those who, one year after pregnancy, were normal. RESULTS: Five years after pregnancy 49 women were normal, 5 had developed type 1 diabetes and were not considered, 6 had developed IGT, and 10 type 2 diabetes. Analysis of variables during pregnancy showed that those variables predicting type 2 diabetes were pre-pregnancy BMI, gestational week of diagnosis, need for insulin therapy, obesity, and plasma glucose at 60' OGTT. Analysis of variables evaluated one year after pregnancy showed that BMI, fasting and post-prandial plasma glucose, plasma glucose at each point of the OGTT, and plasma insulin at 30' OGTT were predictive of the development of type 2 diabetes. Furthermore, age, post-partum fasting plasma glucose, and plasma glucose under OGTT post-partum were predictive of the development of IGT. Our data show for the first time that, also in a Caucasian Mediterranean population, markers of the future development of diabetes do exist, as reported in literature. They also stress the importance of correct identification of GDM patients, in order to screen those at greater risk of developing diabetes, for whom it is imperative to set up prevention programs.

China: lowering maternal mortality in Miyun County, Beijing.

In Miyun County in China the medical authorities registered an elevated maternal mortality ratio which needed to be verified in order to design corrective changes. A decision was taken in 1988 to start a project of pilot interventions in the organization of maternal health services and access for obstetric emergencies. A control and pilot area were chosen in order to test the validity of the interventions. The reduction in maternal mortality from the main complications (postpartum haemorrhage and eclampsia) was impressive and no more maternal deaths were registered in the pilot area with reference to these causes. The overall maternal mortality ratio per 100,000 live births dropped by more than 75% in the pilot area throughout the three-year implementation period. It was therefore shown that the synergistic effect of additional training of medical workers and traditional birth attendants, improved health education, the provision of easier access to emergency care services, the establishment of obstetric rescue teams at the county level, generally improved MCH services, and strengthened management capacity for high risk pregnancies were the most appropriate interventions to lower maternal mortality.

Back school programs. The pregnant patient and her partner.

We believe that couples contemplating pregnancy should consider it to be a 12-month experience, taking 3 months prior to conception to change diets, lifestyles, and exercise routines, so as to maximize overall health. We encourage expectant parents to use the information and approach presented in back school in purchasing car seats and other equipment for child care activities. The Alexander Technique approach to posture and body mechanics can be a powerful adjunct to back school. It is being taught privately, in clinical settings, and in universities throughout the United States. Benefits range from relieving neck and back pain to improving body mechanics in child care activities. This approach to working with the mind and body as a whole enables patients to further help themselves without having to depend on long-term therapy in the reduction of overall musculoskeletal problems. Health care practitioners, working as a team, have an important role to play in the prevention and control of back pain in expectant women and their partners. Patient education, in individual or group form, can help to prepare patients and their partners to handle the stresses and strains of pregnancy, birth, and child care activities.

[Treatment of chronic bovine endometritis and factors for treatment success].

In a controlled field trial, 178 dairy cows with chronic endometritis and at least 21 days in lactation were randomly assigned to four different treatment groups: prostaglandin F2alpha intramuscularly (PG, 5 mg dinoprost (5 ml Dinolytic), n = 51), intrauterine antibiotics (AB; 400 mg ampicillin + 800 oxacillin (20 ml Totocillin), n = 49), intrauterine antiseptics (AS; 100 ml 4% Lotagen, n = 50); control (C, no initial treatment, n = 28). Before treatment, uterine swabs for bacteriologic examination and blood samples for determination of serum progesterone concentrations were collected. Two weeks following the first treatment, cows were reexamined. In case no clinical cure was diagnosed, treatment was repeated and control cows were treated for the first time with one of the three treatments mentioned above. The four treatment groups did not differ with respect to the clinical cure or reproductive performance. Therefore, factors that might have an influence on clinical cure and fertility were evaluated. With increasing duration of lactation, the clinical cure after a single treatment increased significantly over all treatment groups from 59.5% (treatment before day 42 postpartum) to 79.6% (treatment following day 42 postpartum) (P < 0.05). Within the PG group, a statistically significantly higher cure rate after a single treatment and first service conception rate and a lower pregnancy index were obtained when the treatment was performed following day 42 postpartum (P < 0.05). This was not the case in the other treatment groups. A retarded involution of the uterus based on the size had a negative effect on clinical cure over all groups (first treatment clinical cure: 68.2% (small uteri) vs 44.4% (large uteri); P < 0.05). Within groups, this effect was also detected, but only as a trend (P > 0.05). Isolation of Arcanobacterium (A.) pyogenes negatively influenced first treatment clinical cure over all treatment groups (79.0% vs 31.5%) and within treatment groups (P < 0.05). In the AB group, the pregnancy index, days open and the interval from first insemination to conception increased compared with the other treatment groups, when A. pyogenes was detected. Isolation of unspecific bacteria and the presence or absence of a corpus luteum only had minor effects over all and within the PG, AS and C group. Within the AB group, presence of luteal tissue was connected with a higher pregnancy index and increased days open and interval from first insemination to conception (P < 0.05). A multivariate analysis revealed that the presence of A. pyogenes and no initial treatment (control group) had a statistically significant independent and negative influence on the first treatment clinical cure. Ill-smelling vaginal discharge and no treatment had a negative independent effect on first service conception rate. Furthermore, days open were negatively influenced by the interval from calving to first examination and the presence of ill-smelling vaginal discharge. In conclusion, under the conditions of this field study, it seems preferrable to treat chronic endometritis. However, under the condition of a herd health program with continuous observation of sick and healthy animals, a wait-and-see attitude might also be justified.
