Point prevalence of antibiotic usage in major referral hospital in Turkey.

INTRODUCTION: The most important and undesirable consequence of inappropriate antibiotic use is the spread of antibiotic resistance, increased adverse effects, increased mortality and healthcare costs. We aimed to assess antibiotic usage characteristics in inpatient setting in our center. MATERIALS AND METHODS: A one-day, single center point-prevalence study was carried out on June 9th 2021, in Ankara City Hospital in Turkey. Data of antibiotic consumption, appropriateness of usage and predictors of inappropriate use in adult patients were evaluated. RESULTS: Out of 2640 adult patients, 893 (33.8%) were receiving at least one antibiotic. A total of 1212 antibiotic prescriptions with an average of 1.44±0.64 were found. Antibiotics were most commonly used for therapeutic purpose (84.7%), followed by surgical prophylaxis (11.6%). Majority of therapeutically used antibiotics were empirical (67.9%). Infectious diseases consultation was present in 68.3% with a compliance rate of 95.7%. Rate of inappropriate use was 20%. The most frequent cause of inappropriateness was unnecessary use (52.5%). Most commonly and most inappropriately used antibiotics were carbapenems (17.5%) and first generation cephalosporins (38.7%), respectively. Most of the inappropriateness observed in first-generation cephalosporins was due to inappropriate longer surgical prophylaxis. While age is an independent risk factor for inappropriate antibiotic use (p = 0.042), COVID-19 unit admission, use for therapeutic purpose and infectious diseases consultation were protective factors (p<0.001, p<0.001, p<0.001). CONCLUSION: Rate of inappropriate use was low, but inappropriate surgical prophylaxis remains an important problem in surgical units. There is a considerable need to implement an antimicrobial stewardship program that focuses on surgical prophylaxis practices.

The utility of systemic immune-inflammation index and systemic immune-response index in the prediction of adverse outcomes in pregnant women with coronavirus disease 2019: Analysis of 2649 cases.

AIM: To investigate the association of systemic immune-inflammation index (SII) and systemic immune-response index (SIRI) with adverse perinatal outcomes in pregnant women with coronavirus disease 2019 (COVID-19). METHODS: The cases were divided into (1) the Mild-moderate COVID-19 group (n = 2437) and (2) the Severe-critical COVID-19 group (n = 212). Clinical characteristics, perinatal outcomes, SII (neutrophilXplatelet/lymphocyte), and SIRI (neutrophilXmonocyte/lymphocyte) were compared between the groups. Afterward, SII and SIRI values were compared between subgroups based on pregnancy complications, neonatal intensive care unit (NICU) admission, and maternal mortality. A receiver operator characteristic analysis was performed for the determination of optimal cutoff values for SII and SIRI in the prediction of COVID-19 severity, pregnancy complications, NICU admission, and maternal mortality. RESULTS: Both SII and SIRI were significantly higher in complicated cases (p < 0.05). Cutoff values in the prediction of severe-critical COVID-19 were 1309.8 for SII, and 2.3 for SIRI. For pregnancy complications, optimal cutoff values were 973.2 and 1.6. Cutoff values of 1045.4 and 1.8 were calculated for the prediction of NICU admission. Finally, cut-off values of 1224.2 and 2.4 were found in the prediction of maternal mortality. CONCLUSION: SII and SIRI might be used in combination with other clinical findings in the prediction of poor perinatal outcomes.

An evaluation of the results of convalescent plasma therapy applied to pregnant women diagnosed as COVID-19- positive in a pandemic center: A prospective cohort study.

BACKGROUND: Convalescent plasma (CP) might be an additional treatment modality in COVID-19. The aim of this study was to compare CP-related clinical characteristics and perinatal outcomes in pregnant women with mild or moderate-severe COVID-19. METHODS: This prospective cohort study included 36 pregnant women (12 mild and 24 moderate-severe), who underwent CP therapy. The CP obtained from recently recovered donors was transfused to patients together with maximum supportive care and antiviral agents. The groups were then compared in respect of clinical characteristics, laboratory parameters, obstetric complications, and neonatal outcomes. RESULTS: Significant differences were determined between the groups in respect of systemic corticosteroids in COVID-19 treatment (41.7%, 87.5%, p = 0.004), oxygen (O2) support (0%, 91.7%, p < 0.001), chest imaging (41.7%, 58.3%, p = 0.02), intensive care unit admission (0%, 20.8%, p = 0.03) and length of hospitalization (5.5 versus 9.5 days, p < 0.001). The O2 saturation levels before and after administration of CP were significantly lower in the moderate-severe COVID-19 group (p < 0.05). The O2 therapy time before and after administration of CP and total O2 therapy time were significantly lower in the mild COVID-19 group (p < 0.05). Platelet, plateletcrit and lymphocyte counts were significantly higher in both the mild and moderate-severe COVID-19 groups after treatment compared to the pretreatment values (p < 0.05). DISCUSSION: Although data on the results of CP treatment in pregnant women are somewhat limited, it has been suggested that early CP treatment may be associated with improvements in laboratory and ventilatory parameters in pregnant women with mild and moderate-severe COVID-19. Nevertheless, there is a need for further, randomized controlled studies on this subject with the inclusion of greater numbers of patients.

The Association of Serum Electrolytes with Disease Severity and Obstetric Complications in Pregnant Women with COVID-19: a Prospective Cohort Study from a Tertiary Reference Center.

Introduction To evaluate the association of serum electrolytes with disease severity and obstetric complications in pregnant women with Coronavirus disease 2019 (COVID-19). Materials and Methods This prospective cohort study was conducted on pregnant women with confirmed COVID-19. Study population was divided into two groups: 1) Mild COVID-19 group (n = 811) and 2) Moderate/severe COVID-19 group (n = 52). Demographic features, clinical characteristics, obstetric complications, and serum electrolytes were compared between the groups. Afterward, a correlation analysis was performed to investigate the association between serum electrolyte disturbances with COVID-19 severity and obstetric complications. Results Highest serum sodium, hypernatremia, potassium replacement, hypopotassemia, hyperchloremia, initial serum magnesium, hypermagnesemia, and hypocalcemia were significantly higher in the moderate/severe COVID-19 group. The lowest serum sodium, lowest serum potassium, and initial serum calcium were significantly higher in the mild COVID-19 group (p < 0.05). Statistically significant positive weak correlations were found between hypernatremia, hypopotassemia, hyperchloremia, hypermagnesemia, hypocalcemia and COVID-19 severity (r values were 0.27, 0.20, 0.12, 0.18 and 0.12, p values were < 0.001, < 0.001, 0.02, 0.03 and 0.03, respectively). Furthermore, statistically significant positive weak correlations were found between hypopotassemia, hypochloremia, hypermagnesemia, and obstetric complications (r values were 0.10, 0.10, and 0.28, p values were 0.004, 0.03, and 0.001, respectively). A statistically significant negative weak correlation was found between hypomagnesemia and obstetric complications (r = - 0.23 and p = 0.01, respectively). Conclusion Electrolyte disturbances in pregnant women with COVID-19 seem to be associated with disease severity and obstetric complications.

Experience of a tertiary pandemic centre on the labour and delivery of 337 pregnant women with COVID-19: a prospective cohort study from Turkey.

The aim of the present study is to share the experience of a tertiary reference pandemic centre on the labour and delivery of pregnant women with coronavirus disease 2019 (COVID-19). This prospective cohort study was conducted on pregnant women with COVID-19 (n = 337). Patients were divided into two groups based on their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) positivity (n = 103 positive and n = 234 negative) during the delivery. Thereafter, clinical characteristics and perinatal outcomes were compared between the groups. Moreover, delivery characteristics and clinical features were compared between primary caesarean section (n = 117) and normal spontaneous vaginal delivery cases (n = 100). Labour induction was performed in 16% of cases with a failure rate of 35%. Caesarean rate was 70% and the most common indication was worsening in maternal condition. Significant, positive and moderate correlations were observed between COVID-19 severity at admission (r = 0.422, p<.001), radiologic findings consistent with COVID-19 (r = 0.400, p<.001), the necessity for oxygen support during the delivery (r = 0.406, p<.001) and postpartum worsening in maternal condition. A significant, positive weak correlation was found between caesarean delivery and postpartum worsening in maternal condition (r = 0.176, p<.001). COVID-19 seems to be associated with increased rates of obstetric complications and caesarean delivery.Impact StatementWhat is already known on this subject? Increased rates of foetal distress and caesarean section were reported in pregnant women with COVID-19. Appropriate management of labour and delivery in infected pregnant women is crucial to obtain favourable perinatal outcomes.What do the results of this study add? COVID-19 seems to be associated with increased rates of obstetric complications and caesarean delivery. PCR positive group had significantly higher primary and prelabor caesarean delivery rates. Severe/critic COVID-19 infection rate was significantly higher in the primary caesarean group. Significant, positive and moderate correlations were observed between COVID-19 severity at admission, radiologic findings consistent with COVID-19, the necessity for oxygen support during the delivery and postpartum worsening in maternal condition. A significant, positive weak correlation was found between caesarean delivery and postpartum worsening in maternal condition.What are the implications of these findings for clinical practice and/or further research? Management and delivery of pregnant women with COVID-19 should be individualised. The findings of the present study may lead to the establishment of future obstetric protocols in this special population.

Comparison of clinical features and perinatal outcomes between pre-variant and post-variant periods in pregnant women with SARS-CoV-2: analysis of 1935 cases.

PURPOSE: To compare the clinical features and perinatal outcomes of pregnant women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the pre-variant and post-variant periods. METHODS: This prospective cohort study includes pregnant women with SARS-CoV-2 who were followed-up at Ankara City Hospital between 11, March 2020 and 15, September 2021. Demographic features, clinical characteristics and pregnancy outcomes were compared between the pre-variant (n = 1416) and post-variant (n = 519) groups. RESULTS: The rates of severe and critical cases significantly increased in the post-variant group (9.7% vs 2%, p < 0.001). The rates of respiratory support (26.8% vs 7.3%, p < 0.001), ICU admission (12.9% vs 1.8%, p < 0.001) and maternal mortality (2.9% vs 0.4%, p < 0.001) were significantly higher in the post-variant group. A significant increase was observed for pregnancy complications in the post-variant group (45.6% vs 18.8%, p = 0.007). The rates of preterm delivery (26.4% vs 4.4%, p < 0.001) and NICU admission (34% vs 18.8%, p < 0.001) were significantly higher in the post-variant group. Positive, weak, statistically significant correlations were observed between the post-variant period, disease severity and maternal mortality (r = 0.19, r = 0.12 and p < 0.001). CONCLUSION: Post-variant COVID-19 period was associated with a severe course of the disease and increased rates of adverse obstetric outcomes in pregnant patients.

Management of pregnant women with COVID-19: A tertiary pandemic center experience on 1416 cases.

The aim of this study is to share the comprehensive experience of a tertiary pandemic center on pregnant women with COVID-19 and to compare clinical outcomes between pregnancy trimesters. The present prospective cohort study consisted of pregnant women with COVID-19 who were followed up at Ankara City Hospital between March 11, 2020 and February 20, 2021. Clinical characteristics and perinatal outcomes were compared between the pregnancy trimesters. A total of 1416 pregnant women (1400 singletons and 16 twins) with COVID-19 were evaluated. Twenty-six (1.8%) patients were admitted to the intensive care unit (ICU) and maternal mortality was observed in six (0.4%) cases. Pregnancy complications were present in 227 (16.1%) cases and preterm labor was the most common one (n = 42, 2.9%). There were 311, 433, and 672 patients in the first, second, and third trimesters of pregnancy, respectively. Rates of mild and severe/critic COVID-19 were highest in the first and second trimesters, respectively. The hospitalization rate was highest in the third trimester. Pregnancy complications, maternal mortality, and NICU admission rates were similar between the groups. The course of the disease and obstetric outcomes may be different among pregnancy trimesters. A worse course of the disease may be observed even in pregnant women without any coexisting health problems.

Can Anakinra and corticosteroid treatment be an effective option in pregnant women with severe Covid-19?

Anakinra, which is an Interleukin-1 (IL-1) receptor antagonist with the advancing disease process, has started to be considered as an alternative treatment for Covid-19 patients with cytokine storms. We evaluated the effect of corticosteroids and IL-1 receptor blockage with anakinra on pregnant patients with Covid-19 at high risk for respiratory distress, ongoing fever, deterioration in their general condition and consequently maternal and fetal complications. Fourteen pregnant women who received anakinra (median dosage: 400 mg) and corticosteroid (methylprednisolone-median dosage: 80 mg) treatment were evaluated retrospectively. Patients were assessed according to the World Health Organization (WHO) scale. The mortality rate of the cohort was 7.1%, the median hospitalization period of the patients was 15 days and 2 patients had premature births. Covid-19 was found to have a similar spectrum of symptoms in pregnant and non-pregnant women, such as dyspnea, cough and fever. Our study was the first to analyze the combined treatment of corticosteroid and anakinra in pregnant patients with pneumonia from Covid-19 based on the WHO scoring system. Due to the obscurity in the treatment process in pregnant patients, studies are ongoing on managing Covid-19 infection in these patients. We presume that the early use of anakinra and corticosteroid treatments in patients severely infected with Covid-19 may have positive effects on disease progression and survival.

Perinatology clinic in the coronavirus disease-2019 pandemic: what harms, often teaches.

BACKGROUND: Compartmental models simplify the mathematical modeling of infectious diseases based on reported cases. In the absence of precautions, personal protective equipment, quarantine and social distancing, a Susceptible-Exposed-Infectious-Recovered (SuEIR) model with Unscented Kalman Filter for coronavirus disease-19 (COVID-19) Forecasts in Turkey has revealed 174 641 infected people on August 15, 2020, whilst the reported case was 12 216. Through numerical experiments, the effects of quarantine, social distancing, and COVID-19 testing on the dynamics of the outbreak varies. We herein present the documentation of the work in a perinatology clinic during COVID-19 pandemic to find the reflection in a pandemic hospital as even in the pandemic, pregnancy complications and fetal diagnosis/therapy are time-sensitive and cannot be delayed. During the prevention of the horizontal transmission to the health-care workers (HCWs), testing all pregnant women with nasopharyngeal/oropharyngeal swabs for severe acute respiratory syndrome coronavirus (SARS-COV-2) undergoing birth, ultrasound examinations, invasive procedures appear to be the gold standard so that appropriate precautions can be taken if the screen is positive. Though it is logical, it may be incompatible with a busy obstetric practise as a pending polymerase chain reaction (PCR) result should never delay any emergent procedure. OBJECTIVE: We aim to describe the development of COVID-19 disease of 408 HCW out of 1462 by the exposure to pregnant women while providing obstetric care in a single tertiary perinatology unit under strict clinical triage, recommended precautions and wearing personal protective equipment and compare the maternal and perinatal outcome with those of the preceding three months. STUDY DESIGN: A prospective cohort study involving the pregnant women and the HCW with positive PCR for SARS-COV-2 were carried out to correlate with the horizontal transmission while documenting the perinatal work. RESULTS: 25 HCW, including nurses/midwives: 11, doctors: 7 and health technicians: 3 and support staff: 4 developed positive PCR for SARS-COV-2 while providing healthcare to 162 cases: mild-moderate (n = 146), severe (n = 12) and critical (n = 1) and asymptomatic (n = 3) in obstetric population. 22 out of 25 HCW were working in the perinatology unit. COVID-19 clinic was asymptomatic (n = 8), mild-moderate (13) or severe (n = 2) in HCW. However, "Exposed" group in the SuEIR model, both the pregnant women and the HCW that have already been infected and have not been tested, which have been also capable of infecting the "Susceptible" group could not be determined. Some of the HCW and the pregnant women in the "Exposed" group were tested and transferred to the "Infectious" group (which were reported to be PCR positive), while the rest of them who recovered, transitted to the so-called "Unreported Recovered" group. The ratio of the women with severe pre-eclampsia admitted to intensive care unit increased significantly during the lockdown (p = .01). CONCLUSIONS: In a nonstop pandemic perinatology clinic, exposure to 162 PCR positive pregnant women may be correlated with a 5.4% (22/408) documented horizontal transmission in the frontline HCW despite clinical triage and personal protective equipment.

The effect of real-time polymerase chain reaction cycle threshold values on perinatal outcomes of pregnant women with COVID-19.

OBJECTIVE: To evaluate the effect of cycle threshold (Ct) values on the pregnancy outcomes of women with coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: This prospective cohort study was conducted on pregnant women with COVID-19. A real-time polymerase chain reaction (RT-PCR) assay of a nasopharyngeal and oropharyngeal specimen was used for the diagnosis. Initial Ct values for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR tests were recorded. 22.9 was the 50th percentile Ct value of the study population. The study population was divided into two groups based on their Ct values: (1) Cases with Higher Ct values (Ct > 22.9)(n = 50) and (2) Cases with lower Ct values (Ct ≤ 22.9)(n = 55). Demographic features, clinical characteristics, disease progression, laboratory test results and pregnancy outcomes were compared between the groups. A receiver operating characteristic (ROC) curve was used to assess the performance of Ct values in predicting obstetric complications. RESULTS: Obstetric complication rate was significantly higher in cases with lower Ct values (p < .001). A significantly lower lymphocyte count together with higher ESR, procalcitonin and IL-6 values were observed in the cases with lower Ct values (p > .05). Additionally, a significantly higher NICU admission rate and longer hospital stays were present in the cases with lower Ct values (p > .05). The value in ROC curves with the best balance of sensitivity/specificity was 22.5 (85.7% sensitivity, 63.6% specificity). CONCLUSION: Lower Ct values may be associated with an increased rate of obstetric complications in pregnant women with COVID-19. Physicians should be cautious in the management of cases with Ct levels below 22.5.

Updated experience of a tertiary pandemic center on 533 pregnant women with COVID-19 infection: A prospective cohort study from Turkey.

OBJECTIVE: To investigate the clinical course and impact of coronavirus disease 2019 (COVID-19) infection on pregnant women. METHODS: A prospective cohort study was conducted on pregnant women with confirmed COVID-19 infection. Demographic features, clinical characteristics, and perinatal outcomes were prospectively evaluated. RESULTS: Of the 533 cases, 161 (30.2%) had co-morbidities and 165 (30.9%) were asymptomatic. Cough (n = 178, 33.4%) and myalgia (n = 168, 31.5%) were the leading symptoms. In total, 261 patients (48.9%) received COVID-19 therapy, 509 (95.5%) had mild disease, 7 (1.3%) were admitted to the intensive care unit (ICU), and invasive mechanical ventilation was necessary in 2 (0.4%) patients. Maternal mortality was observed in 2 (0.4%) cases. Of the patients, 297 (55.7%) were hospitalized, 39 (7.3%) had suspicious radiologic imaging findings, 66 (12.4) had pregnancy complications (preterm delivery [n =22, 4.1%] and miscarriage [n =12, 2.2%] were the most common pregnancy complications), 131 births occurred, and the cesarean section rate was 66.4%. All neonates were negative for COVID-19. The rate of admission to the neonatal ICU was 9.9%. One specimen of breast milk was positive for the infection. CONCLUSION: The course of COVID-19 was mild in the majority of cases. However, increased rates of pregnancy complications and cesarean delivery were observed.

The rate of SARS-CoV-2 positivity in asymptomatic pregnant women admitted to hospital for delivery: Experience of a pandemic center in Turkey.

OBJECTIVE: To investigate the rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positivity in asymptomatic pregnant women admitted to hospital for delivery in a Turkish pandemic center. STUDY DESIGN: This prospective cohort study was conducted in Ankara City Hospital between April, 15, 2020 and June, 5, 2020. A total of 206 asymptomatic pregnant women (103 low-risk pregnant women without any defined risk factor and 103 high-risk pregnant women) were screened for SARS-CoV-2 positivity upon admission to hospital for delivery. Detection of SARS-CoV2 in nasopharyngeal and oropharyngeal samples was performed by Real Time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) method targeting RdRp (RNA dependent RNA polymerase) gene. Two groups were compared in terms of demographic features, clinical characteristics and SARS-CoV-2 positivity. RESULTS: Three of the 206 pregnant women participating in the study had positive RT-PCR tests (1.4 %) and all positive cases were in the high-risk pregnancy group. Although, one case in the high-risk pregnancy group had developed symptoms highly suspicious for COVID-19, two repeated RT-PCR tests were negative. SARS-CoV-2 RT-PCR positivity rate was significantly higher in the high-risk pregnancy group (2.9 % vs 0%, p = 0.04). CONCLUSION: Healthcare professionals should be cautious in the labor and delivery of high-risk pregnant women during the pandemic period and universal testing for COVID-19 may be considered in selected populations.

A pandemic center's experience of managing pregnant women with COVID-19 infection in Turkey: A prospective cohort study.

OBJECTIVE: To evaluate the course and effect of coronavirus disease 2019 (COVID-19) on pregnant women followed up in a Turkish institution. METHODS: A prospective, single tertiary pandemic center cohort study was conducted on pregnant women with confirmed or suspected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Positive diagnosis was made on a real-time polymerase chain reaction (RT-PCR) assay of a nasopharyngeal and oropharyngeal specimen. Demographic features, clinical characteristics, and maternal and perinatal outcomes were evaluated. RESULTS: SARS-CoV-2 was suspected in 100 pregnant women. Of them, 29 had the diagnosis confirmed by RT-PCR. Eight of the remaining 71 cases had clinical findings highly suspicious for COVID-19. Ten (34.5%) of the confirmed cases had co-morbidities. Cough (58.6%) and myalgia (51.7%) were the leading symptoms. COVID-19 therapy was given to 10 (34.5%) patients. There were no admissions to the intensive care unit. Pregnancy complications were present in 7 (24.1%) patients. Half of the births (5/10) were cesarean deliveries. None of the neonates were positive for SARS-CoV-2. Samples of breastmilk were also negative for the virus. Three neonates were admitted to the neonatal intensive care unit. CONCLUSION: The clinical course of COVID 19 during pregnancy appears to be mild in the present study.

Influenza infections in the 2014-2015 season and pregnancy outcomes.

INTRODUCTION: The most recent influenza season saw a prominent infectious burden over a period of six months in the Turkish capital, reminding observers of the pandemic in 2009 year. The aim of the present study was to investigate the consequences of seasonal outbreaks in pregnant women during the 2014-2015 influenza season. METHODOLOGY: Forty-seven pregnant female patients with symptoms of influenza-like illness who were admitted to tertiary perinatal care center in Ankara, Tukrey, between October 2014 and May 2015 were included in this case-control study. The subtype determination of influenza was performed with real-time reverse transcriptase-polymerase chain reaction (RT-PCR) testing. Clinical observations and pregnancy outcomes were compared with respect to subtypes. RESULTS: Classifications were available for 35 patients, of whom 12 were determined to have influenza A infection, while 10 had influenza B infection. The remaining 13 patients were influenza-negative. Eight of the 22 (36.4%) influenza-positive patients delivered their babies in the preterm period (< 37 weeks). The corresponding rate was 8.3% (1/12) in the influenza-negative group. This difference was not statistically significant (p = 0.077). CONCLUSIONS: Preterm deliveries in pregnant women did not differ significantly among influenza-postive and influenza-negative pregnant women in non-vaccinated study population. Further studies with larger sample sizes may provide more supporting results.

Pandemic influenza H1N1 2009 virus infection in pregnancy in Turkey.

OBJECTIVES: To describe the clinical characteristics of the pregnant women who were hospitalized in a tertiary referral hospital with pandemic influenza H1N1 2009 virus infection and neonatal outcomes from October 2009 to December 2009 during which the pandemic influenza cases peaked in Turkey. MATERIALS AND METHODS: Twenty-five pregnant women who were hospitalized with influenza-like illness and who had laboratory confirmation for pandemic influenza H1N1 virus infection were evaluated prospectively. RESULTS: Of the 25 patients, 4 (16%) were in the first trimester, 8 (32%) were in the second trimester, and 13 (52%) were in the third trimester. The median time from the onset of symptoms to the initiation of antiviral therapy was 1 day (range 1-9 days). Nineteen (76%) patients received oseltamivir treatment. It took 1.6 days on the average for the fever defervescence after the initiation of treatment or hospitalization. Of the 14 patients who underwent chest radiography, three had findings consistent with pneumonia. The mean duration of hospitalization was 4.8 days. Four women (16%) were admitted to an intensive care unit, but there were no maternal or neonatal deaths in this series. At the time of their H1N1 hospitalization, seven women delivered by cesarean at 33-40 weeks gestation, two vaginally at 38 weeks gestation, and two had an abortion at 10 weeks and 16 weeks of gestation, respectively. None of the infants had any evidence of influenza infection. CONCLUSION: Pregnant women are at increased risk for complications from pandemic influenza H1N1 virus infection. Timely medical attention with early recourse to antiviral therapy is associated with a better outcome in H1N1-affected pregnant women.

Asymptomatic bacteriuria and antibacterial susceptibility patterns in an obstetric population.

Introduction. Asymptomatic bacteriuria (ASB), occurring in 2-11% of pregnancies, is a major predisposition to the development of pyelonephritis, which is associated with obstetrical complications, such as preterm labor and low birth weight infants. The aim of this study was to determine the prevalence of ASB, the antibacterial susceptibilities of the isolated microorganisms and the associated risk factors in an outpatient clinical setting in Zekai Tahir Burak Women's Health Education and Research Hospital in Ankara, Turkey. Material and Methods. Between December 2009 and May 2010, pregnant women admitted to the antenatal outpatient clinic were included in this study. The results of a complete urine analysis, midstream urine culture and antibacterial susceptibility were evaluated. Results. Of the 2011 pregnant women included, 171 had ASB (8.5%). E. coli was the most frequently isolated microorganism (76.6%), followed by Klebsiella pneumonia (14.6%). Both microorganisms were highly sensitive to fosfomycin, sensivity being 99.2% for E. coli and 88% for Klebsiella pneumonia. Conclusions. In this certain geographical region, we found E. coli as the most common causative agent of ASB in the obstetric population and it is very sensitive to fosfomycin. We recommend fosfomycin for ASB in pregnant women due to its high sensitivity, ease of administration and safety for use in pregnancy.

Dealing with pandemic influenza A during postpartum and early neonatal period in a busy family-centered neonatal intensive care unit.

Although most infections with the current pandemic H1N1 virus have been self-limited, the risk of influenza complications is higher in some subpopulations. Pregnant women had an increased risk of influenza complications in two past epidemics (1918-1919 and 1957-1958). Since neonates do not have a well-developed immune system, they are also vulnerable to viral infections and its complications. This article reports the interventions and health care planning strategies for pandemic influenza A, and its seasonal results in a tertiary perinatal care center with annually 20,000 deliveries.
