The impact and effect of emotional resilience on performance: an overview for surgeons and other healthcare professionals

Medicine and surgery can be demanding professions with high levels of burnout, but few healthcare professionals are given training or education in the management of stress, and the ability of individuals to cope with work and other pressures is often taken for granted. Emotional resilience - the ability to recover from a stressful event, whether at work or at home - is influenced by factors that are both within and outside our control. In this review, we provide an overview of emotional resilience for surgeons and other healthcare professionals, and focus on the factors that can be modulated to help us cope with difficult or complex situations. We also discuss the importance of teamwork and camaraderie, which can easily be forgotten in busy working practice. A greater awareness and understanding of emotional resilience and ways to cope with stress and pressure at work are essential if we are to look after ourselves better, improve the work of our teams, and provide the best care for our patients.

Management of fetal alloimmune thrombocytopenia-a less invasive option?

Fetal alloimmune thrombocytopenia (FAITP) is a condition associated with significant infant morbidity and mortality. We report on the West of Scotland experience of 30 pregnancies complicated by FAITP over a 17-year period (1982-98). Management options included serial cordocentesis together with platelet transfusion, and maternal intravenous gammaglobulin (IVIgG) therapy. Of those pregnancies managed by serial cordocentesis all had poor outcomes. Weekly IVIgG was administered to the remaining pregnancies, all of which had a good outcome although four infants were thrombocytopenic at birth. None of these cases had previously been complicated by intracranial haemorrhage. In the milder end of the spectrum of FAITP we would suggest that IVIgG is an alternative treatment option.

The cost-effectiveness of outpatient (at home) cervical ripening with isosorbide mononitrate prior to induction of labour

OBJECTIVES

To assess the cost-effectiveness of outpatient (at home) cervical ripening with isosorbide mononitrate (IMN) prior to induction of labour.

DESIGN

Economic evaluation was conducted alongside a randomised placebo controlled trial (the IMOP trial).

SETTING

Large UK maternity hospital.

POPULATION

A total of 350 nulliparous women with a singleton pregnancy, cephalic presentation > or = 37 weeks gestation, requiring cervical ripening prior to induction of labour.

INTERVENTIONS

Isosorbide mononitrate (n = 177) or placebo (n = 173) self-administered vaginally at home at 48, 32 and 16 hours prior to the scheduled time of admission for induction.

RESULTS

Mean health service costs between the period of randomisation and discharge for mother and infant were 1254.86 pound sterling in the IMN group and 1242.88 pound sterling in the placebo group, generating a mean cost difference of 11.98 pound sterling (bootstrap mean cost difference 12.86 pound sterling; 95%CI: -106.79 pound sterling, 129.39 pound sterling) that was not statistically significant (P = 0.842). The incremental cost per hour prevented from hospital admission to delivery was 7.53 pound sterling. At the notional willingness to pay threshold of 100 pound sterling per hour prevented from hospital admission to delivery, the probability that IMN is cost-effective was estimated at 0.67. This translated into a mean net monetary benefit of 98.13 pound sterling for each woman given IMN.

CONCLUSIONS

Although the probability that IMN is cost-effective approaches 0.7 at seemingly low willingness to pay thresholds for an hour prevented from hospital admission to delivery, our results should be viewed in the light of the clinical findings from the IMOP trial.

CMV Infection In Multiple Pregnancy — The Unpredictability Of Infectivity And Affectivity

Congenital CMV infections are the commonest congenitally transmitted infections affecting 0.5 to 2 % of all live births around the globe.1 Here we report a case of congenital CMV infection in a woman with a triplet pregnancy with variable outcomes in all three fetuses.

Heparin-induced thrombocytopenia: recent experience in a large teaching hospital

BACKGROUND

Heparin-induced thrombocytopenia (HIT) is a potentially serious adverse reaction caused by platelet-activating antibodies.

AIM

To describe experience with HIT.

METHODS

Twenty-two patients identified by laboratory records of heparin-associated antibodies with a 50% or greater decrease in platelet count were reviewed in our 600-bed metropolitan teaching hospital from 1999 to April 2005.

RESULTS

There was an increase in the frequency of HIT diagnosed during the review period, which was associated with a rise in the number of requests for HIT antibodies. Thrombotic complications were identified in 14 of 22 patients with HIT. Mean age was 65 years, and 11 patients were men. Seven patients died and HIT was considered contributory in four. One patient required mid-forearm amputation. Unfractionated heparin was used in all cases and five patients also received enoxaparin. Mean time to HIT screen, reflecting when the diagnosis was first suspected, was 14 days. Platelet nadir ranged from 6 x 10(9)/L to 88 x 10(9)/L, with a percentage drop in platelet count of 67-96%. Alternative anticoagulation (danaparoid) was not used in three patients, two of whom died.

CONCLUSIONS

HIT is a potentially life-threatening complication of heparin therapy, associated with a fall in platelet count and a high incidence of thromboembolic complications. It is most frequently seen using unfractionated heparin therapy. The increase in frequency of HIT diagnosed in our hospital appears to be associated with a greater awareness of the entity, although detection is often delayed. Platelet count should be monitored in patients on heparin and the presence of antiplatelet antibodies determined if HIT is suspected. Treatment involves both discontinuation of heparin and the use of an alternative anticoagulant such as danaparoid because of the persisting risk of thrombosis.

Prediction of preterm delivery in twin pregnancy: a prospective, observational study of cervical length and fetal fibronectin testing

OBJECTIVE

To evaluate prospectively cervical length measurements and fetal fibronectin detection as predictors of spontaneous preterm delivery in an unselected population of twin pregnancies.

METHODS

Transvaginal ultrasound assessments of cervical length were performed serially at 18, 24, 28 and 32 weeks' gestation. Receiver-operating characteristic curves were generated at each time point to determine the optimal cut-off for cervical length and rate of change in cervical length in the prediction of preterm delivery (< 35 weeks). A bedside assay for the detection of fetal fibronectin in the maternal vaginal secretions was performed prior to cervical length measurements from 24 weeks. Likelihood ratios (LRs) were used to assess the performance of each test.

RESULTS

The spontaneous preterm delivery rate was 16.5% in 91 studied twin pregnancies. A cervical length </= 25 mm at 18 weeks (LR+ 9.7, sensitivity 14.3%) and </= 22 mm at 24 weeks (LR+ 9.6, sensitivity 28.6%) were the best predictors of preterm delivery. A shortening of cervical length >/= 2.5 mm per week between 18 and 28 weeks' gestation also predicted preterm delivery (LR+ 10.8, sensitivity 16.7%). There was no relationship between the detection of fetal fibronectin and preterm delivery.

CONCLUSIONS

This study confirms the value of transvaginal ultrasound assessment of cervical length as a predictor of preterm delivery in twin pregnancies. However, the poor sensitivity of this test makes it unsuitable as a single predictor of preterm delivery. Fetal fibronectin testing does not identify twin pregnancies destined to deliver prematurely.

An audit of neonatal respiratory morbidity following elective caesarean section at term

Studies have suggested that a reduction in neonatal respiratory morbidity may be achieved by delaying elective caesarean section until 39 weeks gestation. In 1997 staff at the Glasgow Royal Maternity Hospital were concerned at the level of neonatal respiratory morbidity following elective caesarean section.

AIMS

To determine the extent of neonatal respiratory morbidity following elective caesarean section at term. Then to present the findings, make recommendations and perform a repeat analysis.

METHODS

A retrospective analysis of all elective caesarean sections at term between October 1996 and October 1997 was performed. Labour ward, operating theatre and SCBU records were examined, followed by maternal and infant case note review. The gestational age at the time of caesarean section and any neonatal respiratory morbidity was recorded. The results were subsequently presented at a perinatal morbidity meeting and a recommendation made to delay elective sections until 39 weeks gestation. The audit was repeated between June 1999 and June 2000.

RESULTS

The first cycle of the audit showed significantly lower rates of neonatal admissions with advancing gestation (p < 0.001). There was also a reduction in the number of infants requiring oxygen (p = 0.001), the number of infants requiring intensive care admission (p = 0.001) and ventilation (p = 0.003) with advancing gestation. In the second cycle of the audit there was a significant decrease in the number of elective caesarean sections performed prior to 39 weeks gestation (51% vs. 26%) (p < 0.0001). There were fewer neonatal admissions with respiratory morbidity between the two phases of the audit (26/292 vs. 18/327) (RR = 0.62, 95% CI 0.34-1.1). There was also a reduction in the number of infants requiring oxygen (RR = 0.5, 95% CI 0.23-1.06) the number of infants requiring intensive care admission (RR = 0.45, 95% CI 0.15-1.29) and the number of infants requiring ventilation (RR = 0.38, 95% CI 0.1-1.47).

CONCLUSION

A reduction in neonatal respiratory morbidity can be achieved by delaying elective caesarean section until 39 weeks gestation.

Vaginal application of the nitric oxide donor isosorbide mononitrate for preinduction cervical ripening: a randomized controlled trial to determine effects on maternal and fetal hemodynamics

OBJECTIVE

Our aim was to assess the effects of vaginally administered isosorbide mononitrate (a nitric oxide donor) on maternal and fetal hemodynamics in pregnant women at term.

STUDY DESIGN

We conducted a randomized controlled trial. Women were randomly selected to receive vaginally administered isosorbide mononitrate, 20 mg (n = 13) or 40 mg (n = 11), or to undergo a vaginal examination only (n = 12). Maternal pulse, blood pressure, and fetal heart rate were recorded at baseline and then every 30 minutes until 360 minutes. Umbilical artery resistance index and pulsatility index measurements were performed at 0, 180, and 330 minutes.

RESULTS

Maternal pulse rate was greater after the administration of isosorbide mononitrate, 20 or 40 mg, compared with the pulse rate in the vaginal examination-only group (greatest difference in means, 21 beats/min; P <.01). Maternal systolic and diastolic blood pressures were greater in the 20-mg and 40-mg isosorbide mononitrate groups than in the vaginal examination-only group (greatest difference in mean systolic and diastolic blood pressure, 15 and 16 mm Hg, respectively; P <.02 and P <.001, respectively). Fetal heart rate was greater in the 40-mg isosorbide mononitrate group than in either the 20-mg isosorbide mononitrate group or the vaginal examination-only group (difference in mean, 15 beats/min; P <.05). No woman required treatment for maternal or fetal tachycardia or maternal hypotension. Neither dose of isosorbide mononitrate had a significant effect on umbilical artery resistance or pulsatility index.

CONCLUSIONS

Vaginal administration of 20 or 40 mg isosorbide mononitrate to pregnant women at term has an effect on both maternal and fetal hemodynamics, but this effect is not clinically significant.

Differential distribution of endothelin receptor subtypes in placentae from normal and growth-restricted pregnancies

The endothelins (ETs) are potent vasoconstrictor peptides that bind to two distinct receptors, ETA and ETB. This study compares the localization of ETA and ETB receptors in placentae complicated by intrauterine growth retardation (IUGR) and abnormal umbilical Doppler waveform, gestationally matched controls, fetuses that were small for gestational age (SGA), and normal term placentae. Quantitative autoradiography was performed using ETA and ETB subtype-selective ligands. Both ETA and ETB receptors were expressed in the human placenta. Gestational and fetal size effects on the receptor density within stem villi were found, but no effect of abnormal placental blood flow could be demonstrated. A distinct spatial distribution of receptor subtypes within the placenta was observed. Smooth muscle cells expressed both receptors with ETA expression predominant in the proximal regions of the villous tree and ETB abundant in the periphery and decidua. Both receptors were also expressed at lower density on paravascular stromal cells in stem villi. Although these data do not demonstrate aberrant localization of ET receptors in IUGR and SGA placentae, the spatially distinct distribution of ET receptors in the human placenta suggests that ETs play a role in modulation of placental blood flow.

A review of caesarean sections at 30 weeks gestation or less in the west of Scotland 1988-1989

A retrospective study was carried out of caesarean sections at 30 completed weeks of gestation or less between 1/1/88 and 31/12/89 in Glasgow and The West of Scotland. One hundred and thirty-three caesarean sections were carried out resulting in 150 babies. Fifteen (11.3%) of these were classical sections. There were 30 neonatal deaths. The perinatal mortality rate was 170 per 1000. Survival was related to increasing gestation from 27 weeks onwards and also to birthweight from 900 grams onwards. In-utero transfers fared badly with seven out of 21 babies (33%) failing to survive beyond the neonatal period. Although survival continues to improve in newborns, the use of caesarean section should still be viewed with caution as the benefits in the very premature situation with regard to infant survival may be outweighed by the increased maternal morbidity both in the present pregnancy and future pregnancies.

Patterns of blood-brain barrier breakdown in inflammatory demyelination

The evolution of the changes in the blood-brain barrier (BBB) in chronic relapsing experimental allergic encephalomyelitis (CREAE), a model of immune-mediated demyelination, has been studied by magnetic resonance imaging (MRI); gadolinium-DTPA (Gd-DTPA) was used to detect BBB breakdown by both quantitative and qualitative techniques. Animals with acute EAE were examined for comparison. In animals with CREAE an approximately linear relationship was found between the mean number of lesions enhancing with Gd-DTPA seen per MRI slice and the severity of clinical disability at relapse. In addition, a direct relationship was seen between the duration of clinical relapse and the duration of enhancement with Gd-DTPA for lesions associated with the relapse. Lesions studied in animals having entered a progressive phase of disease showed the most sustained BBB breakdown. These observations suggest that BBB breakdown is important in the development of clinical signs in inflammatory demyelination. In CREAE, areas of focal enhancement with Gd-DTPA could usually be clearly defined at a time of clinical relapse. In slices free of focal lesions, no abnormal Gd-DTPA leakage could be detected using a quantitative method. In contrast, in acute EAE no focal lesions were visible, but significant leakage was detected by measurement. No change was found in T2 relaxation times in CREAE or acute EAE. The pattern of BBB breakdown in inflammatory demyelination evolves from a diffuse shortlived disturbance in acute EAE to a more focal and prolonged breakdown in animals with chronic relapsing and progressive disease. The broad similarities in the pattern of BBB breakdown seen in CREAE and multiple sclerosis support the hypothesis that the initial vascular changes in the human disease are due to inflammation which could be mediated immunologically.

Audit of medical response to antenatal booking history

A retrospective review of 600 obstetric case-notes, covering the years 1978 to 1984, was performed independently by two assessors. The medical response to 22 risk factors, recorded at booking by the midwife, was assessed. The medical staff recognized 69% of the risk factors recorded at booking and responded appropriately to 82% of these. The standard of care improved over the period studied. The accuracy of our conclusions was greatly enhanced by carrying out each assessment in duplicate with arbitration by a third assessor when necessary, and it is proposed that all audits of medical practice should themselves be audited in this way.

Infiltrating angiolipoma or intramuscular hemangioma? A report of five cases

We report five cases of tumors composed primarily of angiomatous and adipose tissue occurring within skeletal muscle in relatively young individuals. Pain is frequently the presenting symptom. The tumors have been described in the literature as angiolipomas, infiltrating angiolipomas, and intramuscular hemangiomas. A discussion of the use of these terms is included. It is our conclusion the term "intramuscular hemangioma" is most appropriate for these lesions.

Primary adenovillous carcinoma of the bladder

Two cases of primary adenovillous carcinoma of the bladder are presented: one in a normally placed bladder and the other in an exstrophied bladder. The close association of these 2 neoplasms with coexistent cystitis glandularis would seem to support the possible precancerous nature of the latter entity. The remarkable similarity of these neoplasms to villous adenocarcinomas of the rectum is also described, a finding which may reflect the close embryologic origin of the rectum and bladder neck. A brief review of the classification of vesical adenocarcinomas is also given.
