Vaginal aerobic bacteria of healthy bitches and those with fertility problems

The most common problems in veterinary practice in bitches are bacterial infections of the reproductive tract associated with fertility problems. Research to determine the correlation between the health status of female dogs and bacterial flora of the genital tract has been ongoing for years, but the results obtained by different authors are often contradictory, and do not always concern breeding bitches. Our study identified the most common aerobic bacteria in the genital tract of numerous breeding bitches population. A total of 275 breeding dogs in anestrous phase of the estrous cycle were included in this study. 198 were qualified to the first group with no genital tract infections and no reproductive disorders. 68 bitches were qualified to the second group with complications such as: infertility, abortion, foetus resorptions and newborn mortality. The type of bacterial isolates was almost the same in the healthy bitches and the group with fertility problems. The most common bacteria obtained from the vaginal tract of the tested dogs were Streptococcus spp., Staphylococcus spp., Mycoplasma canis and Escherichia coli. There were no significant differences in bacterial prevalence in the group with reproductive problems versus healthy dogs; however, we found a statistically significant difference between both groups when the numbers of bacterial strains were compared. The number of one-strain bitches was statistically higher in the problematic group than in the non-problematic one. Bacterial culturing of vaginal swab specimens from breeding bitches without clinical signs of genital disease is of little value. Furthermore, it should always be preceded by an examination (clinical, cytological or vaginoscopy etc.). The request or requirement to perform vaginal cultures that is made by some breeders, while common, is not diagnostic for any pathologic condition and the results of these cultures should never be used to determine if antibiotic therapy is indicated.

Perceptions of the COVID-19 Pandemic among Women with Infertility: Correlations with Dispositional Optimism

People who are more optimistic may experience better psychological health during stressful times. The present study examined the perceptions and emotions surrounding the COVID-19 pandemic among American women who were experiencing fertility problems. We tested if dispositional optimism in these women was associated with less negative perceptions and emotions. We conducted a cross-sectional survey of patients from a single private infertility and reproductive clinic in an urban area in the Midwest, United States. Women, age 18 or older, primarily White and educated, who presented for an appointment to the clinic were invited to participate in an email-based survey. Respondents (N = 304) reported their perceived impact of the COVID-19 pandemic on fertility treatment, emotions associated with this impact, and perceived stress and depressive symptoms. They also completed measures of dispositional optimism and expectations for a future pregnancy. Findings indicated that women perceived an overall negative impact of the pandemic on their treatment plans, which was associated with more negative emotions, lower expectations of future pregnancy, and greater stress and depressive symptoms during the pandemic. However, further correlational analyses revealed that being higher in trait optimism was associated with perceiving a less negative impact of the pandemic, experiencing fewer negative emotions, and less overall stress and depressive symptoms. Although women with fertility problems have perceived the pandemic as negative and disruptive, those who are higher in optimism may be less affected.

Fertility Problems and Parenting Daily Hassles in Childhood: A 7-year Longitudinal Study of Adoptive Parents

Fertility problems are known to exert a negative impact on psychological health. Meanwhile, individuals with fertility challenges often view adoption as a positive healing experience. Yet, a dearth of work has examined the long-term impact that fertility problems have on adoptive parents and their childrearing stress. Here, we investigated how fertility problems related to parenting daily hassle (PDH) trajectories among adoptive mothers and fathers in the Early Growth and Development Study (N = 333). When adopted children were 9 months old, adoptive parents reported whether they had fertility problems prior to their decision to adopt and rated their PDH frequency and intensity on six occasions over the next 7 years. Multilevel models revealed inverse U-shaped curves for PDH among both fertile and infertile parents, such that PDH increased from child age 9 months until about 5 to 6 years and decreased thereafter. Mothers with fertility problems exhibited a steeper PDH incline from 9 months to the peak at child age 5 to 6, but also incurred a swifter subsequent decline. There were no significant differences in fathers' PDH trajectories based on fertility problems. We discuss why fertility problems appear to impact PDH trajectories for mothers rather than fathers.

Molecular characterization of small supernumerary marker chromosomes derived from chromosome 14/22 detected in adult women with fertility problems: Three case reports and literature review

RATIONALE

Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes, which can be detected in patients with developmental retardation, infertile problems, and prenatal fetus. We report 3 adult female with fertility problems carrying sSMC(14/22) and aim to explore the correlation between sSMC(14/22) and fertility problems in women.

PATIENT CONCERNS

Three Chinese female patients were referred for infertility consultation in our hospital.

DIAGNOSES

The karyotype of these 3 patients were 47, XX, +mar. The chromosome microarray analysis (CMA) detected various chromosomal duplications and deletions in the 3 cases: a 0.49Mb gain of 5q32 for case 1; a 0.54Mb gain of 14q32.33 and a 1.83Mb gain of 16p11.2 for case 2; a 0.37Mb loss of 13q21.2q21.31 and a 0.12Mb gain of Xp11.2 for case 3. Fluorescence in situ hybridization (FISH) using the specific probes for chromosomes 13/21, 14/22, and 15 was applied to identify the origination of these sSMC, which were all finally identified as sSMC(14/22).

INTERVENTIONS

Case 1 underwent the artificial reproductive technology to get her offspring and finally delivered a healthy male infant at 39 weeks. Case 2 did not plan to choose in vitro fertilization (IVF) to get offspring. Case 3 refused to do assisted reproductive technology.

OUTCOMES

The genotype-phenotype correlation of sSMC(14/22) remain unclear. However, the existence of sSMC(14/22) might negatively affect the fertility ability in sSMC female carriers.

LESSONS

The combined application of traditional banding technique and molecular cytogenetic techniques can better identify more details of sSMC. For sSMC carriers with fertility problems, they could get their offsprings through assisted reproductive technologies after comprehensive fertility assessment.

Isolation of Tetracycline-Resistant Chlamydia suis from a Pig Herd Affected by Reproductive Disorders and Conjunctivitis

Due to various challenges in diagnosing chlamydiosis in pigs, antibiotic treatment is usually performed before any molecular or antibiotic susceptibility testing. This could increase the occurrence of tetracycline-resistant Chlamydia (C.) suis isolates in the affected pig population and potentiate the reoccurrence of clinical signs. Here, we present a case of an Austrian pig farm, where tetracycline resistant and sensitive C. suis isolates were isolated from four finishers with conjunctivitis. On herd-level, 10% of the finishers suffered from severe conjunctivitis and sows showed a high percentage of irregular return to estrus. Subsequent treatment of whole-herd using oxytetracycline led to a significant reduction of clinical signs. Retrospective antibiotic susceptibility testing revealed tetracycline resistance and decreased susceptibility to doxycycline in half of the ocular C. suis isolates, and all isolates were able to partially recover following a single-dose tetracycline treatment in vitro. These findings were later confirmed in vivo, when all former clinical signs recurred three months later. This case report raises awareness of tetracycline resistance in C. suis and emphasizes the importance of preventative selection of tetracycline resistant C. suis isolates.

Medicinal Plants Used for Treating Reproductive Health Care Problems in Cameroon, Central Africa1

Medicinal Plants Used for Treating Reproductive Health Care Problems in Cameroon, Central Africa. Approximately 80% of the African population uses traditional plants to deal with health problems, basically because of their easy accessibility and affordability. This study was carried out to document indigenous knowledge of medicinal plants used by traditional healers and elders in the treatment of reproductive health care in the Bamboutos Division of the West Region in Cameroon, Central Africa. The research methods used included semi-structured interviews and participative field observations. For the interviews, 70 knowledgeable respondents (40 traditional healers and 30 elders) were selected via purposive sampling. Voucher specimens were collected with the help of respondents, processed into the Cameroon National Herbarium in Yaoundé following standard methods, identified with the help of pertinent floras and taxonomic experts, and submitted to Department of Botany at the University of Dschang. Descriptive statistics were used to analyze and summarize ethnobotanical information obtained. Informant consensus factors (ICF) were used to elucidate the agreement among informants on the species to be used in the treatment within a category of illness. The results showed that a total of 70 plant species from 37 families (mostly of the Asteraceae [8 species], Euphorbiaceae [7], and Acanthaceae and Bignoniaceae [4 each]) are used in the treatment of 27 reproductive ailments, with the highest number of species (37) being used against venereal diseases, followed by female (29) and male infertility (21), respectively. Leaves (47.3%) were the most commonly harvested plant parts and the most common growth forms harvested were the herbs (45.7%), followed by shrubs (30%). Sixty percent of plant material was obtained from the wild ecosystems. Herbal remedies were mostly prepared in the form of decoction (66.2%) and were taken mainly orally. Informant consensus about usages of medicinal plants ranged from 0.5 to 1.0 with an average value of 0.91. It can be concluded that medicinal plants have played and will continue to play major roles in the management of reproductive healthcare in the study area.

Fertility problems and risk of gestational diabetes mellitus: a nationwide cohort study

OBJECTIVE

To determine whether women with a history of fertility problems have a higher risk of gestational diabetes mellitus (GDM) than women without a history of fertility problems after adjustment for maternal factors.

DESIGN

Nationwide population-based cohort study.

SETTING

Not applicable.

PATIENT(S)

All live and stillbirths during 2004-2010 among women with fertility problems (n = 49,616) and women without fertility problems (n = 323,061) were identified by linkage between the Danish Medical Birth Registry and the Danish Infertility Cohort. Information on GDM was obtained from the Danish National Patient Registry.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Odds ratios and 95% confidence intervals for the association between fertility problems and risk of GDM after adjustment for potentially confounding factors, including maternal age, prepregnancy BMI, parity, parental history of diabetes, level of education, and smoking during pregnancy.

RESULT(S)

In total, 7,433 (2%) pregnant women received a diagnosis of GDM. Multivariate analysis showed that pregnant women with a history of fertility problems had a statistically significantly higher risk of GDM than pregnant women without fertility problems. In stratified analyses, the association between fertility problems and risk of GDM attenuated with increasing age and was more pronounced among primiparous women and women with polycystic ovary syndrome.

CONCLUSION(S)

Our findings suggest that pregnant women with a history of fertility problems are at increased risk of GDM.
