BackgroundAlthough there are public policies for eradicating congenital syphilis, they do not seem to be a routine in most health services. The objective of this study was to evaluate the management of sexual partners of pregnant women with syphilis in primary health care in northeastern Brazil.MethodsThis is a qualitative assessment carried out from February to October 2014 in the city of Fortaleza, Ceará, northeastern region of Brazil, through the observation of six primary health care centers and interviews with 21 professionals, six coordinators, nine women diagnosed with syphilis during antenatal care and four sexual partners. The data were submitted to thematic content analysis.ResultsImportant flaws were identified at the primary health centers studied regarding the management of syphilis during pregnancy. Accessing testing and treatment is difficult, and there are no standardized strategies to notify the partner. The responsibility for notifying them is transferred to the women, and counseling does not offer proper guidance nor sufficient emotional support to help them.ConclusionThe management of pregnant women and their sexual partners in our region does not comply with global recommendations. Professional qualification, sensitization, and standardization of health professionals’ conduct are necessary. Offering support to health professionals on their clinical practices by means of a supervision process may contribute to the adoption of the recommended guidelines and to the promotion of care based on privacy, respect, confidentiality of information, and awareness of the problems faced by women as a result of syphilis diagnosis.Electronic supplementary materialThe online version of this article (10.1186/s12913-019-3910-y) contains supplementary material, which is available to authorized users.

Previous work has shown that intraperitoneal administration of riparin III (ripIII) reduces immobility time in the forced swimming test (FST), which suggests potential antidepressant activity. As the mechanism of action is not completely understood, this study is aimed at investigating the antidepressant-like action of ripIII. Following intraperitoneal administration of ripIII at doses of 25 and 50 mg/kg, there were decreases in the immobility time in the FST and tail suspension test without accompanying changes in ambulation (data not shown). The pretreatment of mice with sulpiride (50 mg/kg, i.p.), prazosin (1 mg/kg, i.p.), yohimbine (1 mg/kg, i.p.), and p-chlorophenylalanine (PCPA, 100 mg/kg, i.p. for, four consecutive days) significantly prevented the anti-immobility effect of ripIII in the FST. On the other hand, the anti-immobility effect of ripIII (50 mg/kg, v.o.) was not altered by pretreatment of mice with SCH23390 (15 μg/kg, i.p.) Furthermore, ripIII potentiated the sleeping latency and sleeping time of the pentobarbital-induced sleeping time test and also potentiated apomorphine (16 mg/kg, i.p.)-induced hypothermia in mice. In conclusion, the present study provides evidence that the antidepressant-like effect of ripIII is dependent on its interaction with the serotonergic, noradrenergic (α₁- and α₂- receptors), and dopaminergic (dopamine D₂ receptors) systems.

The results of this work contribute information regarding the antinociceptive properties of CAT on acute pain and show that, at least in part, TRPV1, TRPM8, ASIC, glutamate receptors, PKC and PKA participate in CAT's antinociceptive mechanism.

Riparin II (RipII), an alkamide isolated from the green fruit of Aniba riparia, was tested in the various animal models of inflammation to investigate its anti-inflammatory activity. Male Wistar rats (180-240g) were treated with RipII by gavage at doses 25 or 50mg/kg, before initiating the inflammatory responses. The tests used were paw edema induced by carrageenan, dextran, histamine or serotonin; peritonitis induced by carrageenan and fMLP, as well as the measurement of MPO activity, TNF-α and Il-1β amount in the peritoneal fluid. In the animal models of carrageenan and dextran-induced paw edema, the animals treated with RipII showed lower edema than those of the control group. Treatment with RipII also reduced the paw edema induced by histamine but not serotonin. In the carrageenan-induced peritonitis model, treatment with RipII reduced leukocyte migration, the MPO activity and the amount of TNF-α and IL-1β in the peritoneal fluid. In summary, these results indicate that RipII has an anti-inflammatory activity in chemical models of acute inflammation. RipII might be directly or indirectly inhibiting the activity, production or release of pro-inflammatory mediators involved in the generation of the pain associated with inflammation.
