Review
Diabetes mellitus (DM) is a chronic metabolic disorder in which blood glucose level raises that can result in severe complications. However, the incidence increased mostly by obesity, pregnancy, persistent corpus luteum, and diestrus phase in humans and animals. This review has focused on addressing the possible understanding and pathogenesis of spontaneous DM in canine, feline, and few wild animals. Furthermore, pancreatic associated disorders, diabetic ketoacidosis, hormonal and drug interaction with diabetes, and herbal remedies associated with DM are elucidated. Bibliographic search for the present review was done using PubMed, Scopus, and Google Scholar for articles on concurrent DM in small and wild animals. Persistent corpus luteal and pseudopregnancy in female dogs generate gestational DM (GDM). GDM can also be caused by extensive use of drugs/hormones such as glucocorticosteroids. Although many similarities are present between diabetic cats and diabetic humans which present islet amyloidosis, there was a progressive loss of β- and α-cells and the normal number of δ-cells. The most prominent similarity is the occurrence of islet amyloidosis in all cases of diabetic cat and over 90% of human non-insulin dependent DM Type-2. Acute pancreatic necrosis (APN) occurs due to predisposing factors such as insulin antagonism, insulin resistance, alteration in glucose tolerance, obesity, hyperadrenocorticism, and persistent usage of glucocorticoids, as these play a vital role in the progression of APN. To manage such conditions, it is important to deal with the etiological agent, risk factors, diagnosis of diabetes, and hormonal and drug interaction along with its termination with suitable therapy (herbal) protocols. It should be noted that the protocols used for the diagnosis and treatment of human DM are not appropriate for animals. Further investigations regarding diabetic conditions of pets and wild animals are required, which will benefit the health status of all animals health worldwide.

BACKGROUND
There is a dearth of literature on pseudopregnancy in the bitch, with only a few treatment-based studies published since the 1990s. Pseudopregnancy may be under-recognised in bitches and may account for a proportion of behavioural cases seen in veterinary practices including aggression. Little is known about commonly used treatments for overtly pseudopregnant bitches and it is possible that current regimes may not be prescribed for a sufficient duration to control any clinical signs including, physical and behavioural changes. To investigate current trends in diagnosis and treatment of canine pseudopregnancy, a postal survey was sent to 2000 randomly selected veterinary surgeons in UK veterinary practices. The questionnaire queried how often vets recognise cases of pseudopregnancy in spayed and entire bitches, which physical or behavioural signs are commonly recognised for diagnosis, and which management or treatment protocols are used.
RESULTS
The response rate was 19.8% (397/2000). Ninety-six percent of veterinary surgeons reported seeing pseudopregnant bitches showing behavioural changes without any physical changes within the last 12 months. Of those behavioural changes, collecting and mothering objects was the most frequently reported behavioural sign (96%). Ninety-seven percent of vets had seen aggression in pseudopregnant bitches. Nevertheless, only 52% of vets routinely asked owners about behavioural changes during consultations. Forty-nine percent of respondents reported seeing pseudopregnancy in spayed bitches. The most commonly reported physical sign was enlarged mammary glands and/or milk production (89%). Treatment options varied (surgical, medical or none) and depended on duration and severity of physical and behavioural signs, owners' preference, cost, concurrent disease, drug availability and previous history.
CONCLUSIONS
This is the largest epidemiological study of canine pseudopregnancy in the UK. The prevalence and severity of clinical signs in dogs with pseudopregnancy are variable and possibly under-estimated. Dogs with overt pseudopregnancy experience diverse physical and behavioural changes and information on standard treatment protocols are lacking. Although, progress on our understanding of diagnosis and treatment of pseudopregnancy in spayed and entire bitches has been made, further studies are warranted.

Pregnancy determination is difficult in the giant panda (Ailuropoda melanolecua), representing a challenge for ex situ conservation efforts. Research in other species experiencing pseudopregnancy indicates that urinary/fecal concentrations of 13,14, dihydro-15-keto-prostaglandin F2α (PGFM) can accurately determine pregnancy status. Our objective was to determine if urinary PGFM concentrations are associated with pregnancy status in the giant panda. Urinary PGFM concentrations were measured in female giant pandas (n = 4) throughout gestation (n = 6) and pseudopregnancy (n = 4) using a commercial enzyme immunoassay. Regardless of pregnancy status, PGFM excretion followed a predictable pattern: 1) baseline concentrations for 11-19 weeks following ovulation; 2) a modest, initial peak 14-36 days after the start of the secondary urinary progestagen rise; 3) a subsequent period of relatively low concentrations; and 4) a large, terminal peak at the end of the luteal phase. Pregnant profiles were distinguished by an earlier initial peak (P = 0.024), higher inter-peak concentrations (P < 0.001), and a larger terminal peak (P = 0.003) compared to pseudopregnancy profiles. Parturition occurred 23 to 25 days from the initial PGFM surge and within 24 hours of the start of the terminal increase. These pattern differences indicate that urinary PGFM monitoring can be used to predict pregnancy status and time parturition in the giant panda. Furthermore, this is the only species known to exhibit a significant PGFM increase during pseudopregnancy, suggesting a unique physiological mechanism for regulating the end of the luteal phase in the giant panda.

Per DSM-V, pseudocyesis is included under the category "other specified somatic symptom and related disorder" and is defined as a false belief of being pregnant that is associated with objective signs and reported symptoms of pregnancy. The male counterpart of pseudocyesis is Couvade syndrome, also called "sympathetic pregnancy" where a man experiences symptoms of pregnancy when his female partner is pregnant. There are extensive reports on pseudocyesis and Couvade syndrome in psychiatric literature but none with features of both, in a single case. Here we present a unique case of a fifty-eight-year-old mother who presented with symptoms of concomitant pseudocyesis and Couvade syndrome concurrently when her daughter was pregnant. This case report discusses the epidemiology, course of symptoms and common comorbidities associated with this interesting diagnosis.

Comparative Study
OBJECTIVES
The aim of the study was to assess the occurrence of symptoms associated with the Couvade syndrome in two groups of men of Polish and Finnish nationality, and to perform a comparative analysis.
MATERIAL AND METHODS
The study was conducted in two groups of men (expectant fathers): 51 Poles and 40 Finns using a self-constructed questionnaire prepared in Polish and English languages. The statistical analysis was performed in Micro-soft Office Excel 2010 and Statistica 12. The Pearson's test was calculated, and the statistical significance level was p < 0.05.
RESULTS
The most common physical symptoms reported by the Polish men were weight gain (78%) and gastric disorders (80%), whereas the Finns most frequently declared weight gain (60%). As for emotional symptoms, mood swings (p = 0.0001) and sleep disorders (p = 0.00004) were significantly more common in the Poles, whilst the Finns experienced frustration (p = 0.0403) and nervousness (p = 0.01579) significantly more frequently. The Finnish respondents more often used profes-sional forms of preparation for childbirth and parenthood (p = 0.00229).
CONCLUSIONS
Psychosomatic symptoms of the Couvade syndrome are significantly more common in Polish than in Finnish expectant fathers. Compared with Polish fathers, Finns significantly more frequently attend ante-natal classes. Ante-natal care should encompass education of men as they do experience the symptoms of the Couvade syndrome during their wives'/partners' pregnancies.

Until recently, the main selection focus in UK dairy goats has been on milk yield. To develop a selection index suitably weighted for a variety of traits, it is important to understand the genetic relationships between production, health and fertility traits. This study focussed on three aspects of reproduction that are of interest to goat breeders. (1) Out of season (OOS) kidding ability: goats are highly seasonal breeders so achieving consistent, year-round dairy production presents a challenge. It may be possible to select for extended or shifted breeding cycles, however, there are no published studies on the genetic basis of seasonal kidding ability, and a genetic correlation with milk production in dairy goats; (2) age at first kidding (AFK): a reduced AFK offers the opportunity for more rapid genetic improvement, as well as reducing the amount of time and resources required to raise the animals to producing age; (3) pseudopregnancy (PPG): as it is difficult to diagnose pregnancy within 30 days of mating, high herd levels of PPG could add a significant delay in breeding replacement animals, or commencing a new lactation. Using records from 9546 goats, the objective of this study was to investigate the genetic relationships between the reproductive traits described above, and the production traits 520-day milk yield (MY520), lifetime milk yield (MYLife) and lifetime number of days in milk (DIMLife). The 'out of season' phenotype was defined as week of kidding relative to the 4 weeks of the year where the highest average number of births occur. Incidences of PPG that occurred during the first lactation were used as cases, while goats with none were assigned as controls. Relevant fixed and random effects were fitted in the models. In line with other reproduction traits, heritability estimates were low ranging from 0.08 to 0.11. A negative genetic correlation was found between AFK and MY520 (-0.22±0.10), whereas a positive genetic correlation was found between PPG and DIMLife (0.58±0.11). Pseudopregnancy and OOS were positively genetically correlated (0.36±0.15). All other genetic correlations were very low. The results of this study indicate that selection for the reproductive traits analysed is feasible, without adversely affecting MYLife.

BACKGROUND
In the domestic dog, corpora lutea (CL) are the only source of progesterone (P4), both in pregnant and non-pregnant cycles because there is no placental steroidogenesis. The absence of an endogenous luteolysin in absence of pregnancy results in long-lasting physiological pseudopregnancy, strongly contrasting with the acute luteolysis observed prepartum. The underlying biological mechanisms and the involvement of P4 signalling remain, however, not fully understood. Therefore, here, next-generation sequencing (RNA-Seq) was performed on CL from the late luteal phase and compared with normally luteolyzing CL collected at the prepartum P4 decrease.
RESULTS
The contrast "luteal regression over luteolysis" yielded 1595 differentially expressed genes (DEG). The CL in late luteal regression were predominantly associated with functional terms linked to extracellular matrix (p = 5.52e-05). Other terms related to transcriptional activity (p = 2.45e-04), and steroid hormone signalling (p = 2.29e-04), which were more highly represented in late regression than during luteolysis. The prepartum luteolysis was associated with immune inflammatory responses (p = 2.87e-14), including acute-phase reaction (p = 4.10e-06). Immune system-related events were also more highly represented in CL derived from normal luteolysis (p = 7.02e-04), compared with those from dogs in which luteolysis was induced with an antigestagen (1480 DEG in total). Additionally, the withdrawal of P4 at mid-gestation resulted in 92 DEG; over-represented terms enriched in antigestagen-treated dogs were related to the inflammatory response (p = 0.005) or response to IL1 (p = 7.29e-05). Terms related to proliferation, e.g., centrosome organization (p = 0.002) and steroid metabolic processes (p = 0.001), prevailed at mid-gestation. Thereby, our results revealed the nature of luteotropic effects of P4 within canine CL. It appears that, even though they result in diminished steroidogenic output, the effect of antigestagens is more related to the withdrawal of P4 support than to the PGF2alpha-related inflammatory reaction observed at physiological parturition.
CONCLUSIONS
We report the differential gene expression associated with maintenance and cessation of luteal function in pregnant and non-pregnant dogs. Based on the differentially expressed genes, we indicate functional pathways and gene networks that are potentially involved in the underlying endocrine and molecular mechanisms. This study establishes future research directions that may be helpful in understanding some of the clinical conditions, such as luteal insufficiency, associated with negative pregnancy outcome in dogs.

The two terms, pseudocyesis and delusion of pregnancy, were frequently used for pseudopregnancy. Delusion of pregnancy is a special form of hypochondriacal/somatic delusion reported in various psychiatric and organic disorders. The origin of the delusion of pregnancy in schizophrenia has often been explained by psycho-analytic interpretations attributing wish fulfilling, protective role to false beliefs, and mother establishes an undisturbed union with her fetus during pregnancy, which eliminate loneliness and helplessness. The current case is a 49-year-old married female with an illness of total duration of 10 years. Initial symptoms were delusion of infidelity and persecution and 2 and 3 person auditory hallucination; however, the patient started reporting around 2 years back that she was pregnant and there were three female children inside her abdominal cavity rather than in uterus. She was firm on this belief and was not convinced by family members even giving evidence contrary to her belief like showing ultrasonography report. She firmly believed that these are gift of God, and they are special children who would be delivered through special procedure. Blood investigation revealed raised prolactin level, blood sugar and ultra sonography suggestive of cholelithisis. Patient's psychiatric symptoms including delusion of pregnancy were significantly improved with treatment, and medical and surgical comorbidities were managed with appropriate consultations.

Octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) are used as intermediates or monomers in the synthesis of silicon-based polymers for industrial or consumer applications. D4 and D5 may remain as residual monomer in these polymers at less than 1000ppm and may therefore be present as a minor impurity in consumer products. For D5, in addition to the manufacture of polymers, its uses include intentional addition to consumer products, personal care products and some dry- cleaning solvents. Two-year rodent chronic bioassays were conducted with both substances and borderline increases in the incidence of uterine tumors were observed, specifically, benign uterine adenoma with D4 and adenocarcinoma with D5. The effects profile and induction of uterine tumors share some similarity with that seen with chronic exposure to dopamine agonists. The current study investigated the potential for D4 and D5 to elicit dopamine agonist-like effects on estrous cyclicity. Separate groups of reproductively senescent female Fischer 344 rats (F344) were exposed via vapor inhalation to D4 (700ppm, 9.3mg/L) or D5 (160ppm, 2.1mg/L) or to a diet containing 0.0045, 0.045, or 4.5ppm pergolide mesylate (PM), a potent dopamine agonist used here as a reference substance, from 11 through 24 months of age. The primary focus was to characterize the effects of D4 and D5 exposure on estrous cyclicity relative to that observed with PM. As a monitoring effort, circulating endogenous estradiol, progesterone, prolactin and corticosterone levels were evaluated monthly. A blood sample from each rat was obtained via tail vein in the afternoon after the daily inhalation exposure period once every 4 weeks. Histomorphologic examination of the major organs including the reproductive tract was conducted on all animals at study termination. This study has shown that chronic exposure to D4 and D5 can affect cyclicity in the reproductively senescent F344 rat. For each substance the effect on cyclicity involved reduction in the incidence of pseudopregnancy with a shift toward cycles more typical of younger animals. D4 and D5 induced an increase in estrous cycle repetition whereas D4 also increased the incidence of extended estrus. These shifts resulted in animals entering proestrus/estrus significantly more times over the duration of the study than seen in the control group. Similar effects were observed with the reference substance, PM. However, distinct differences in the timing and magnitude of the effects on the estrous cycle and impact on prolactin, progesterone, estradiol, and corticosterone suggest that D4 and D5 are not classical dopamine agonists even though a similar increased incidence of proestrus/estrus was also observed with PM. These results may prove important with respect to understanding D4- and D5-induced uterine tumor response in the F344 rat, given the relationship between increased incidence of uterine endometrium stimulation by endogenous estrogen as a consequence of extended or more frequent proestrus/estrus, uterine tumor risk, and questions of relevance to humans. Recent publications have summarized the existing data on D4 and D5, with emphasis on exploring the biological relevance of the uterine tumors (Klaunig et al., 2016a,b; Franzen et al., 2017; Dekant and Klaunig, 2016; Dekant et al., 2017). The authors concluded that although the mode of action has not yet been fully established, the data, including the findings from this study, indicate that the D4- and D5-induced uterine tumors observed in the rodent chronic bioassays have no relevance for human risk characterization based not only on the distinct species differences in regulation of the reproductive systems, but also the high exposure levels and duration required for expression in rats.
