Effects of epidural analgesia on labor length, instrumental delivery, and neonatal short-term outcome

Purpose

We aimed to clarify whether the short-term adverse neonatal outcomes associated with epidural analgesia are due to the epidural analgesia itself or to the instrumental delivery.

Methods

A retrospective case–control study was conducted to evaluate the relationship between epidural analgesia, labor length, and perinatal outcomes. A total of 350 pregnant women at term who delivered under epidural analgesia (cases) were compared with 1400 patients without epidural analgesia (controls).

Results

Vacuum extraction (6.5 vs. 2.9 %) and cesarean section (19.9 vs. 11.1 %) were more frequently performed in the cases than controls (p < 0.001). Using a Kaplan–Meier algorithm, it was determined that the mean lengths of the 1st and 2nd stages of labor and the overall durations of labor and delivery were significantly longer in cases compared with controls. A Cox regression analysis showed that the longer labor remained even after adjustment for parity. The neonatal variables stratified by mode of delivery were not different in cases and controls, except for a slightly lower umbilical arterial pH in spontaneous delivery for the cases group. However, the Apgar scores and umbilical arterial pH were significantly lower in the neonates delivered by vacuum extraction compared with those in the neonates delivered by spontaneous delivery or cesarean section, regardless of whether epidural analgesia was performed. A multivariable analysis showed that vacuum extraction much more consistently affected the arterial pH than the analgesia itself (the β coefficients were ?0.036 for epidural analgesia vs. ?0.050 for vacuum extraction).

Conclusion

Epidural analgesia was associated with slowly progressing labor, thus resulting in an increased rate of instrumental delivery. This instrumental delivery appears to adversely affect the neonatal outcomes more strongly than the analgesia itself.     

Left ventricular geometry correlates with early repolarization pattern in adolescent athletes

Some forms of early ECG repolarization QRS pattern (ERp) with J‐point elevation of 0.1 mV in two contiguous inferior and/or lateral leads with or without ST‐elevation are potentially associated with a higher arrhythmic risk in adults. We assessed the prevalence of ERp among non‐professional adolescent athletes and correlated it with age, sex, ethnicity, and structural and electric cardiac parameters. We retrospectively analyzed 414 ECGs obtained from young athletes referred to our center from 2006 to 2017. We found ERp in 22% of cases. In the ERp group, we found a greater percentage of black athletes, a higher systolic blood pressure, and lower heart rate (HR) compared with the group without ERp. This pattern was less frequent in female athletes. In athletes with ERp, the occurrence of ventricular ectopic beats was less frequent and QRS‐duration was shorter. They also exhibited greater (a) ECG‐based left ventricular hypertrophy (LVH), (b) left ventricular mass, and (c) relative wall thickness (RWT), suggesting a tendency to concentric geometry. At logistic regression analysis, we found that HR (OR 0.98 [0.96‐0.99] P = .013), QRS‐duration (OR 0.96 [0.94‐0.99], P = .003), LVH (OR 1.09 [1.05‐1.12], P < .001), and RWT (OR 1.08 [1.01‐1.16] P = .032) were significant predictors of ERp incidence. ERp is quite common in adolescent athletes and correlates with concentric LV remodeling. Specific clinical and ECG‐findings related to training such as lower HR, LVH, and QRS‐duration are also predictors of ERp. In adolescent non‐professional athletes, ERp is a benign finding associated with some structural and electric cardiac modifications induced by training.

Same strategy for pitfalls of radiotherapy in different anatomical districts

Oral mucositis (OM) and radiodermatitis (RD) are serious side effects of radiotherapy (RT), often leading to its suspension, need for analgesics, and enteral/parenteral nutrition. Laser therapy is becoming a recommended treatment option. This prospective study aimed at demonstrating the beneficial effect of class IV laser therapy (HPLT) on RT-induced OM, an off-label use of HPLT to treat RD in breast cancer patients. Fifty-three cancer patients, during/after RT and/or chemotherapy (CT), affected by OM, were treated with HPLT during four consecutive days (970?±?15 nm, 5 W (50 %), 35–6000 Hz, 240 s). Assessment of OM (Grading Objective Scale, WHO-SCALE), pain (visual analogue scale, VAS), functional ability, subjective parameters, and site/severity of OM were recorded over time. Similarly, 27 breast cancer patients affected by RD were treated by HPLT and monitored over time for grade, discomfort, itching, and bleeding. Progressive improvement of WHO-SCALE from day 7 on, and of VAS from day 2 on (p?<?0.000) was registered. All patients’ functional capacity improved on day 4 (p?<?0.05). All subjective parameters improved on day 14 (p?<?0.001) except for voice, which improved on day 21 (p?<?0.000). Ulcerations’ dimension and erythema’s severity significantly decreased in all sites examined (p?<?0.05). Similarly, HPLT proved to be beneficial in managing RD for all the parameters considered (p?<?0.002). Regardless of OM grade/site and of kind/site of tumor, HPLT proved to be effective in healing OM as well as RD. In both cases, effective treatment can improve life quality through a safe, easy, innovative approach. Therefore, HPLT may become an integral part of everyday practice in the management of RT adverse effects.     

Long-term outcome and need of re-operation in gastro-esophageal reflux surgery in children

Background

Fundoplication is considered a mainstay in the treatment of gastro-esophageal reflux. However, the literature reports significant recurrences and limited data on long-term outcome.

Aims

To evaluate our long-term outcomes of antireflux surgery in children and to assess the results of redo surgery.

Methods

We retrospectively analyzed all patients who underwent Nissen fundoplication in 8 consecutive years. Reiterative surgery was indicated only in case of symptoms and anatomical alterations. A follow-up study was carried out to analyzed outcome and patients’ Visick score assessed parents’ perspective.

Results

Overall 162 children were included for 179 procedures in total. Median age at first intervention was 43 months. Comorbidities were 119 (73 %), particularly neurological impairments (73 %). Redo surgery is equal to 14 % (25/179). Comorbidities were risk factors to Nissen failure (p = 0.04), especially children suffering neurological impairment with seizures (p = 0.034). Follow-up datasets were obtained for 111/162 = 69 % (median time: 51 months). Parents’ perspectives were excellent or good in 85 %.

Conclusions

A significant positive impact of redo Nissen intervention on the patient’s outcome was highlighted; antireflux surgery is useful and advantageous in children and their caregivers. Children with neurological impairment affected by seizures represent significant risk factors.

     

Ability of herpes simplex virus vectors to boost immune responses to DNA vectors and to protect against challenge by simian immunodeficiency virus

The immunogenicity and protective capacity of replication-defective herpes simplex virus (HSV) vector-based vaccines were examined in rhesus macaques. Three macaques were inoculated with recombinant HSV vectors expressing Gag, Env, and a Tat-Rev-Nef fusion protein of simian immunodeficiency virus (SIV). Three other macaques were primed with recombinant DNA vectors expressing Gag, Env, and a Pol-Tat-Nef-Vif fusion protein prior to boosting with the HSV vectors. Robust anti-Gag and anti-Env cellular responses were detected in all six macaques. Following intravenous challenge with wild-type, cloned SIV239, peak and 12-week plasma viremia levels were significantly lower in vaccinated compared to control macaques. Plasma SIV RNA in vaccinated macaques was inversely correlated with anti-Rev ELISPOT responses on the day of challenge (P value<0.05), anti-Tat ELISPOT responses at 2 weeks post challenge (P value <0.05) and peak neutralizing antibody titers pre-challenge (P value 0.06). These findings support continued study of recombinant herpesviruses as a vaccine approach for AIDS.
