Patient Attitudes toward Gestational Weight Gain and Exercise during Pregnancy.

Body mass index (BMI) and gestational weight gain (GWG) are important factors for neonatal and maternal health. Exercise helps women moderate their BMI and GWG, and provides health benefits to mother and child. This survey study assessed patients' perceptions of counseling they received during pregnancy, their sources of information about GWG, and their attitudes toward exercise during pregnancy. We distributed an anonymous survey to 200 pregnant women over the age of 18 at a tertiary care center in Danville, Pennsylvania. Survey questions included demographics, discussions with medical providers regarding GWG and exercise, and their exercise habits before and during pregnancy. 182 women (91%) responded. Most reported their provider discussed weight and diet (78.8%), expected GWG (81.6%), and exercise during pregnancy (79.8%); however, 28% of obese women and 25% of women who did not plan to exercise during pregnancy reported not receiving exercise counseling. Approximately 20% of women did not plan to exercise during pregnancy. Women decreased the number of days per week they exercised (40.6% with 3 or more days prepregnancy versus 30.7% during pregnancy, P = 0.002). Some patients who did not exercise prior to pregnancy (12%) expressed interest in a personal training session. Among women in the eight month or later, 42.4% were above GWG recommendations. Our study found barriers to adequate activity during pregnancy; 20% of pregnant women not receiving/remembering counseling regarding exercise. Interest in personal training from patients that did not exercise suggests they would benefit from increased efforts to encourage physical activity. Exercise and GWG counseling based in medical science as well as patient psychological needs will help efforts to reduce GWG and improve pregnancy outcomes.

Prevention of preterm birth with pessary in singletons (PoPPS): randomized controlled trial.

OBJECTIVE: To determine if pessary use prevents preterm birth (PTB) in women with singleton pregnancy, with short cervical length (CL) measured on transvaginal sonography (TVS) and without prior spontaneous PTB (sPTB). METHODS: This was an open-label multicenter randomized trial of asymptomatic women presenting at 18 + 0 to 23 + 6 weeks' gestation with a singleton pregnancy, CL ≤ 25 mm on TVS and no prior sPTB. sPTB included those with spontaneous onset of labor and those with rupture of membranes prior to labor. Subjects were randomized to receive either a Bioteque cup pessary or no pessary. Pessaries were inserted by trained maternal-fetal medicine staff. Vaginal progesterone was recommended to women with CL ≤ 20 mm. The primary outcome was PTB < 37 weeks. A sample size of 121 women in each group (n = 242) was needed to detect a reduction in the primary outcome from 30% in the no-pessary group to 15% in the pessary group. The trial was stopped early before complete enrollment. RESULTS: Between 17 March 2014 and 29 July 2016, 17 383 women underwent CL measurement on TVS. Of these, 422 (2.4%) had CL ≤ 25 mm and 391 (92.7%) met the full eligibility criteria, of which 122 (31.2%) agreed to randomization. Sixty-one (50%) women were randomized to the pessary group and 61 (50%) to the no-pessary group. Baseline characteristics were similar between the groups. There were no significant differences between the pessary and no-pessary groups in the rate of PTB < 37 weeks (43% vs 40%; relative risk 1.09; 95% CI, 0.71-1.68) or in secondary outcomes, such as rate of PTB < 34 weeks, rate of PTB < 28 weeks, gestational age at delivery, birth weight and rate of composite adverse neonatal outcome. CONCLUSIONS: Cervical pessary use was not associated with prevention of PTB in women with a singleton pregnancy, short CL on TVS and no prior sPTB in this small, underpowered randomized controlled trial.

The value of open lung biopsy in immunocompetent patients with community-acquired pneumonia requiring hospitalization.

OBJECTIVE: To determine the role of open lung biopsy in immunocompetent patients with community-acquired pneumonia who require hospitalization. DESIGN: A group of 1,118 patients with severe community-acquired pneumonia that required hospitalization were enrolled in the study. Of the patients, 26 underwent open lung biopsy. Another 18 of these patients were immunocompromised and were excluded from this segment of the study. SETTING: Tertiary care 800-bed hospital from November 1981 to May 1989. RESULTS: Progressive diffuse pulmonary infiltrates and negative conventional cultures were the indications for biopsy in most of these patients. Eighteen (69 percent) were immunocompromised. The eight immunocompetent patients underwent a retrospective review of their course in hospital. Three patients died. The diagnostic yield from open lung biopsy was 25 percent. A specific histologic diagnosis was made in one patient--lipoid pneumonia. The pulmonary histologic finding were nonspecific in the remaining patients, but in four, in combination with the clinical data, gave useful information and resulted in therapy change. Culture of a pulmonary tissue yielded cytomegalovirus in one other patient. Serologic testing had a low yield in this group with three patients having a positive result. CONCLUSIONS: Open lung biopsy is rarely necessary in immunocompetent patients with community-acquired pneumonia. In a small group of patients where it is necessary, however, both positive and negative results are important in directing therapy.

Delayed sequelae of pulmonary barotrauma.

Progression of cystic changes in the lung, with development of pneumothoraces long after withdrawal of ventilatory support, was observed in two patients who recovered from adult respiratory distress syndrome. On pathologic examination both pleural and parenchymal cysts were confirmed.

The radiographic features of epidemic and sporadic Q fever pneumonia.

Radiographic dissimilarities exist between the chest radiographs of patients with epidemic and sporadically-occurring Q fever pneumonia. Chest radiographs of 25 patients with Q fever pneumonia were retrospectively assessed, and demonstrated previously unreported differences between these two broad groups. Differing strains of Coxiella burnetii, or varying doses of the pathogen, are postulated as the pathogenetic mechanisms for the observed discrepant findings.

Pneumonia in renal transplant patients.

Between January 1976 and March 1982, 28 episodes of pneumonia occurred in 26 renal transplant patients. The overall mortality rate was 46%. Of the 16 patients with nosocomial pneumonia 9 (56%) died, whereas of the 12 patients with community-acquired pneumonia 4 (33%) died. In all 9 cases of unknown cause the response to empiric treatment was prompt, whereas in 4 of the 10 cases of monomicrobial pneumonia and 8 of the 9 cases of polymicrobial pneumonia the patient died. Cytomegalovirus was the sole cause of the pneumonia in two patients and a contributing cause, along with aerobic gram-negative bacteria, in another five, four of whom also had a fungal infection. Two patients, both of whom survived, had nosocomial Legionnaires' disease.

Radiographic analysis of the course of Legionella pneumonia.

The radiographic findings in the acute phase of Legionella pneumonia are generally non-specific and have been previously documented. A retrospective assessment of 12 patients with this bacterial pneumonia revealed that resolution of the radiographic findings was prolonged in five. The predominant feature in such patients is the transient finding of interstitial consolidation following the air-space consolidation, not unlike that of Mycoplasma or viral pneumonia. Eventual return to normal was evident in three patients and residual parenchymal fibrosis was noted in two patients.

Cryptogenic fibrosing alveolitis.

Clinical, radiographic, and histologic data, together with pulmonary function features, in eleven patients with cryptogenic fibrosing alveolitis, are described in the following study. All these patients presented with a history of exertional dyspnea. Eight of the eleven had radiographic evidence of pleural involvement as manifested by blunting of one or both costophrenic angles. A restrictive defect was present in eight patients, all of whom had x-ray changes showing diffuse involvement. One of the patients presented showed marked improvement in all parameters including a repeat lung biopsy. Immunofluorescent studies of the lung biopsies from six patients revealed no evidence of immunologic damage. Based upon the histologic pattern of pulmonary reaction in the biopsies and the intervals between the onset of symptoms and the time of biopsy, a tenative scheme of temporal evolution of this disease is presented. Lung injury may lead either directly to diffuse interstitial pulmonary fibrosis (DIPF) or lungs may react to injury by an initial alveolar, mural or mixed pattern, all of which might ultimately progress to DIPF. An initial alveolar or mural pattern might change to a mixed pattern.
