ABSTRACT
Radiotherapy is an important treatment of gynecological tumors. Although novel techniques or measures in recemy years have improved the tumor control rate and reduced radiation toxicity, radiation toxicity remains a major problem due to the location of some key organs adjacent to the tumor. A new material-hydrogel, as an organ spacer, provides a new method to reduce the radiotherapy toxicity. In this article, the application of hydrogel as an organ spacer in brachytherapy for gynecological tumors was reviewed from the aspects of hydrogel characteristics, suitable population, mode of injection, interval distance and dose effect, clinical benefits and cost effectiveness, etc.
ABSTRACT
Radiotherapy is a primary method for treating tumors. However, since surrounding healthy tissues may also receive a certain dose of irradiation during the radiotherapy, they may suffer from radiation-induced damage, which is even serious for certain patients. Injectable hydrogels are expected to achieve the spacing between target areas and their surrounding tissues during radiotherapy, thus increasing the dose to the target areas while reducing the risk of radiation-induced damage to surrounding healthy tissues and organs. Accordingly, the quality of life of the patients can be improved. Therefore, applying injectable hydrogels serves as a potential strategy for reducing the adverse reactions associated with radiotherapy. This paper reviews the latest research progress in the spacing and protection of hydrogels in radiotherapy for different tumors.
ABSTRACT
Objective:To explore the consistency of MRI fast field echo resembling a CT using restricted echo-spacing (FRACTURE) and CT in the evaluation of knee and ankle bone changes.Methods:From November 2020 to November 2021, seventeen patients who underwent CT and MRI FRACTURE examinations of knee joint or ankle joint in the First Affiliated Hospital of Dalian Medical University were retrospectively collected, including 14 patients with knee joint examinations and 3 patients with ankle joint examinations. According to the number of joint components, 80 components were included, including 14 for femur and patella, 17 for tibia and fibula, and 3 for talus, scaphoid, medial cuneiform, medial cuneiform, lateral cuneiform and calcaneus, respectively. The fracture, hyperosteogeny, and bone destruction of the joint bones were evaluated by two observers using CT and FRACTURE images, respectively. Kappa test was used to analyze the consistency of CT and FRACTURE images between observers in the evaluation of joint bone lesions.Results:The Kappa values (95%CI) of the consistency evaluation of fracture, hyperosteogeny, and bone destruction by CT and FRACTURE images were 0.925 (0.823-1.027), 0.905 (0.799-1.011) and 0.895(0.752-1.038) respectively for observer 1, and were 0.963 (0.892-1.034), 0.933 (0.843-1.023) and 0.886 (0.731-1.041) respectively for observer 2. The Kappa values (95%CI) of the consistency evaluation of fracture, hyperosteogeny, and bone destruction by observers 1 and 2 via CT images were 1.000 (1.000-1.000), 0.937(0.851-1.023) and 0.945 (0.839-1.051) respectively, and that by FRACTURE images were 0.962 (0.888-1.036), 0.966 (0.899-1.033) and 0.836 (0.656-1.016) respectively.Conclusion:For the evaluation of fracture, hyperosteogeny, and bone destruction of knee joint and ankle joint, MRI FRACTURE sequence is highly consistent with CT.
ABSTRACT
Background: Overpopulation in a community or a country reflects high fertility desires of its citizens. A country can only progress meaningfully if its resources and amenities can provide for all its citizens. Objectives: To examine the childbearing practices of antenatal attendees at the Niger Delta University Teaching Hospital, Okolobiri, Nigeria and whether there is any suggestion of fertility decline or transition. Materials and Methods: A cross-sectional study of two hundred and fifty-two women who had antenatal care in the hospital during the study period. Data was collected using a structured self-administered questionnaire with a reliability coefficient of 0.85. Data collected were analysed using IBM SPSS Statistics version 25. Statistical significance was a p-value <0.05. Results: The mean age of the respondents was 30.5 ± 5.9 years. More than half (53.6%) had tertiary education and 39.3% had secondary education. Only 29.4% were housewives/unemployed. The median parity was 2 and 229 women accounted for previous deliveries of 596 babies. The median desired total number of children was 4 (range 1 to 8). More than half (56.3%) did not believe in spacing after the first child. Seventy-six (30.2%) had no knowledge of modern contraceptives. There was a significant relationship (p - 0.018) between child sex preference and number of births. Conclusion: With a current median parity of two children/woman and desired total number of children of a median of four children/woman, the childbearing practices of the population studied may not result in a fertility rate far below the Nigeria national average of 5.3 children per woman. Nevertheless, a study to derive the total fertility rate in the study population is necessary to determine whether or not there is ongoing fertility transition.

Background: The use of family planning (FP) methods and stockouts of contraceptives are major challenges to the FP program in Sub-Saharan Africa. This study assessed the level of stockouts of contraceptives in Nigerian health facilities. This survey was carried out in 767 health facilities offering FP services across all six geopolitical zones of Nigeria. Materials and Methods: This was a cross-sectional study involving a quantitative technique. Data were collected from 116 private and 651 public health facilities in Nigeria. A structured questionnaire was used to collect data from the facilities, and a physical inventory was taken. Data were analyzed using IBM-SPSS, version 25.0. Results: The stockout rate in the last 3 months was 63.8% in private and 47.5% in public health facilities (P = 0.001), whereas stockouts on the visit day were 63.8% in private and 51.0% in public facilities (P = 0.011). On the day of the visit, the stockout rate in private health facilities ranged from 9.3% to 26.5%, whereas it ranged from 5.3% to 24.2% in public health facilities. The main causes of stockouts of some contraceptives are low/no demand and a lack of supply. Conclusions: This study found a high level of stockouts of FP services in private and public health facilities, but higher in private facilities. Both the poor supply and low demand for FP services in Nigeria require the attention of policymakers and health officials.
ABSTRACT
An experiment was conducted into the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka from October 2019 to March 2020 this study the effect of macronutrients combination and plant spacing on growth and yield of black cumin (Nigella sativa L.). Black cumin variety BARI Kalozira-1 was used as planting material in this study. The experiment consisted of two factors: Factor-A: macro nutrient combinations (4 levels): T1= N0P0K0 kg ha-1 (control), T2= N90P50K40 kg ha-1, T3= N135P75K60 kg ha-1; Factor-B: plant spacing (3 levels): S1= 20 cm × 10 cm, S2= 20 cm × 15 cm and S3= 20 cm × 20 cm. The experiment was laid out in a randomized complete block design with factorial with three replications. Data on different growth, yield and yield contributing parameter of black cumin were recorded and significant variation was observed from different treatments. In case of nutrient combinations, the tallest plant (54.86 cm) was observed from T3 (N135P75K60 kg ha-1) treatment. The maximum primary branch plant-1 (8.62) and secondary branch plant-1 (12.18), flower plant-1 (22.20), capsules plant-1 (19.69) and 1000 seed weight (2.99 g) was observed from T2 (N90P50K40 kg ha-1) treatment. The highest seed yield ha-1 (1.18 t) was observed from T2 (N90P50K40 kg ha-1) treatment. In case of plant spacing the tallest plant (48.34 cm) was observed from S1 (20 cm × 10 cm) treatment. The maximum primary branch plant-1 (7.80) and secondary branch plant-1 (11.23) flower plant-1 (20.26), capsules plant-1 (18.81), 1000 seed weight (2.99 g) were observed from S3 (20 cm × 20 cm) treatment. The highest seed yield ha-1 (1.09 t) was recorded from S1 (20 cm × 10 cm) treatment. It can be concluded that, sowing of black cumin providing 90 kg N, 50 kg P and 40 kg K nutrient combination with 20 cm × 10 cm plant spacing was recorded to be more suitable practice for getting higher amount and quality of seed yield of black cumin.
ABSTRACT
Soccer field grass can be compared to highly sensitive crops regarding water deficit and must be irrigated throughout the year to provide decent conditions for use. For this, efficient irrigation systems are necessary to save water and energy, and this is possible, provided that they are evaluated. Therefore, this paper evaluated the water distribution uniformity, by different methodologies, for an irrigation system installed in a grass soccer field. Also, the influences of multiple spacings between sprinklers and meteorological factors on the final results were assessed. The irrigation system had Falcon 6504 sprinklers, operating at the pressure of 320 kPa. Six field essays were conducted considering overlaying water depths originated from the same irrigation system considering spacings between sprinklers varying from 6 m x 6 m, 6 m x 9 m, 9 m x 9 m, 9 m x 12 m, 12 m x 12 m, 12 m x 15 m, 15 m x 15 m, 15 m x 18 m, 18 m x 18 m, 18 m x 21 m, 21 m x 21 m, 21 m x 24 m, 24 m x 24 m, 24 m x 27 m, 27 m x 27 m, 27 m x 30 m and 30 m x 30 m. The uniformity coefficients used were: Christiansen uniformity coefficient (CU), distribution uniformity coefficient (DU), absolute uniformity coefficient (UA), statistical uniformity coefficient (US), Hart uniformity coefficient (UH) and HSPA standard efficiency (UHSPA). Meteorological data were obtained during the essays. Wind speed caused reduction in the length of the water jet applied by the sprinkler and also caused a bigger effect on the water distribution uniformity. Both CU and UH showed higher values compared to the other coefficients. The increase in the spacing between the sprinklers resulted in reduced water distribution coefficients. To comply with technical and economic criteria, an arrangement of 12 m x 15 m between the Falcon 6504 sprinklers, operating at a 320 kPa pressure, is recommended.

Optimum planting arrangement is an important attribute for efficient utilization of available resources and to obtain high yield of cotton. Application of plant growth promoter and retardant on cotton in improved planting density are the innovative techniques in the establishment of more productive cotton crop. Therefore, we planned a field study to assess the role of bio-stimulant and growth retardant in the resource utilization efficiency of cotton cultivars planted under variable row spacing at Agronomic Research Area Bahauddin Zakariya University and Usmania Agricultural Farm Shujabad during Kharif 2012. Experimental treatments consisted of cotton genotypes viz. CIM-573 and CIM-598, cultivated under conventional (75 cm), medium (50 cm) and ultra-narrow row spacing (25 cm) with foliar spray of bio-stimulant (moringa leaf extract) and growth retardant (mepiquate chloride), either sole or in combination, keeping distilled water as a control. Exogenously applied MLE alone and MLE + MC significantly enhanced the number of squares, flowers and green bolls per plant leading to higher cotton seed and lint yield of CIM 598 cultivar cultivated under conventional row spacing. While application of MC alone and MLE + MC produced maximum micronaire value, fiber strength and fiber uniformity ratio of CIM 573 cultivar cultivated under conventional row spacing. The results suggested that application of MLE is a possible approach to enhance the cotton productivity and the use of MC to enhance the fiber quality attributes under conventional row spacing.

Portanto, foi planejado um estudo de campo para avaliar o papel de um bioestimulante e um regulador de crescimento na eficiência da utilização de recursos de cultivares de algodão plantadas com espaçamento variável entre linhas na Área de Pesquisa Agronômica Universidade Bahauddin Zakariya e Usmania Agricultural Farm Shujabad durante Kharif 2012. Os tratamentos experimentais consistiram em genótipos de algodão viz. CIM-573 e CIM-598, cultivadas sob espaçamento convencional (75 cm), médio (50 cm) e ultraestreito (25 cm) e pulverização foliar de bioestimulante (extrato de folha de moringa) e regulador de crescimento (cloreto de mepiquato)), sozinho ou combinado, mantendo a água destilada como controle. O MLE aplicado exogenamente sozinho e o MLE + MC aumentaram significativamente o número de quadrados, flores e cápsulas verdes por planta, levando a um maior rendimento de sementes e fibra de algodão da cultivar CIM 598 cultivada sob espaçamento convencional entre fileiras. Enquanto a aplicação de MC sozinho e MLE + MC produziu valor máximo de micronaire, resistência da fibra e razão de uniformidade da fibra da cultivar CIM 573 cultivada sob espaçamento convencional entre linhas. Os resultados sugeriram que a aplicação do MLE é uma abordagem possível para aumentar a produtividade do algodão e o uso de MC para aprimorar os atributos de qualidade da fibra no espaçamento convencional entre linhas.

ABSTRACT
ABSTRACT@#Currently dental implant treatment become popular. More clinicians are being presented with the opportunity to perform implant services in their own practice. The use of one-piece implant can be considered as treatment for the replacement of missing tooth in the areas of limited tooth-to-tooth spacing and would bring less trauma for the soft tissue. A 52-year-old female patient presented with difficulty in mastication due to the loss of teeth of 35 region with limitation mesio distal space. Radiology examination did not reveal any radiolucencies in 35 region. Radiograph revealed sufficient bone height from crestal to the floor of the mandible. A one-piece implant was placed in the 35 region. The present case used an endosteal implant, one stage surgery, and delayed loading. Restoration with porcelain fused to the metal crown had been delivered three months after the one-piece implant placement. The result of this treatment indicated that one-piece implant could be considered as an effective therapy choice for replacement of missing tooth in order to rehabilitate the masticatory function.

Transcranial direct current stimulation (tDCS) is a brain stimulation intervention technique, which has the problem of different criteria for the selection of stimulation parameters. In this study, a four-layer real head model was constructed. Based on this model, the changes of the electric field distribution in the brain with the current intensity, electrode shape, electrode area and electrode spacing were analyzed by using finite element simulation technology, and then the optimal scheme of electrical stimulation parameters was discussed. The results showed that the effective stimulation region decreased and the focusing ability increased with the increase of current intensity. The normal current density of the quadrilateral electrode was obviously larger than that of the circular electrode, which indicated that the quadrilateral electrode was more conducive to current stimulation of neurons. Moreover, the effective stimulation region of the quadrilateral electrode was more concentrated and the focusing ability was stronger. The focusing ability decreased with the increase of electrode area. Specifically, the focusing tended to increase first and then decrease with the increase of electrode spacing and the optimal electrode spacing was 64.0-67.2 mm. These results could provide some basis for the selection of electrical stimulation parameters.

Brazil is a major soybean production country and cultivate yearly more than 36 million hectares. Several factors have been reported reducing soybean production and occurrence of diseases is one of the most important. Some diseases such as the pod and stem blight (Diaporthe phaseolorum var. sojae) can limit soybean yield by shortening plant cycle and reducing seed quality. Field experiments were conducted aiming to evaluate the effect of row spacing, soybean cultivar and fungicide application on the incidence of pod and stem blight on soybean. The trial was carried out twice, with planting date at 11/15/2012 and 12/15/2012, in Planaltina-DF, Brazil. Treatments were arranged in a split-split plot scheme obeying the randomized block design. The factors evaluated were row spacing (42, 60 and 75 cm), soybean cultivars ("Syn1180RR" and "Syn1080RR") and spray or not the fungicide Boscalid (500 g a.i./ha) at R1 and R3 soybean growth stages. Disease incidence was assessed on stems at the harvest time and on seeds after harvest and yield was estimated. Results obtained show that broader row spacing increased disease incidence on stems and seed, cultivar "Syn1180RR" was more susceptible than "Syn1080RR" and fungicide application reduced disease incidence. Pod and stem blight significantly reduced soybean yield.
O Brasil é um dos principais países produtores de soja e cultiva anualmente mais de 36 milhões de hectares. Diversos fatores têm sido relatados reduzindo a produção de soja e a ocorrência de doenças está entre os mais importantes. Algumas doenças como a seca da haste e da vagem (Diaporthe phaseolorum var. sojae) podem reduzir a produtividade pelo encurtamento do ciclo e redução na qualidade da semente. Experimentos de campo foram conduzidos com o objetivo de avaliar o efeito do espaçamento entre linhas, cultivares e aplicação de fungicida sobre a incidência da seca da haste e da vagem na soja. O experimento foi conduzido duas vezes, com semeadura da soja em 15/11/2012 e 15/12/2012, em Planaltina-DF, Brasil. Os tratamentos seguiram o esquema de parcelas sub-sub-divididas no delineamento de blocos ao acaso. Os fatores avaliados foram espaçamento entre linhas (42, 60 e 75 cm), cultivares de soja ("Syn1180RR" e "Syn1080RR") e aplicação ou não do fungicida Boscalida nos estádios R1 e R3 da soja. A incidência da doença em hastes e sementes e a produtividade da soja foram mensurados. Os resultados obtidos mostram que espaçamentos mais amplos favorecem maior incidência da doença em hastes e sementes, a cultivar "Syn1180RR" é mais suscetível do que a "Syn1080RR" e a aplicação de fungicida reduz a incidência da doença. A seca da haste e da vagem reduz significativamente a produtividade da soja

Background: Overpopulation is a major problem in 21st century India. 2012 census shows birth rate of 20.97/1000 people and death rate of 7.48/1000 people. Fertility rate in 2019 was 2.28 children per women. Many states implemented 2 child norms. Purpose of study is to understand the number of children preferred.Methods: A Cross sectional study was done amongst 200 primigravida women who attended antenatal clinic at SMC, Shimoga. A predesigned and pretested standard Questionnaire was used to know the number of children preferred, KAP about birth spacing, contraceptive use and unsafe abortions using objective questions.Results: Most women preferred 2 child norms across most subclasses. Most Muslims (85.7%) preferred ?3 children. Though 100% were aware of family planning, only 46% chose to space their next pregnancy. 56.5% were in support of 2-child norm. Family pressure plays crucial role in 83.5% cases and 65.5% still opted sterilization as the first choice for contraception.Conclusions: India with high population density is staring at demographic disaster due to limited life resources. Right attitude towards birth spacing, contraceptive use, avoidance unwanted pregnancies and unsafe abortions is needed. Better female literacy, societal awareness and good medical facility at last mile is crucial. Male partner's involvement in every step is vital.
ABSTRACT
O objetivo do presente estudo foi avaliar os efeitos da implantação de pastagem de sorgo forrageiro com diferentes arranjos populacionais no comportamento animal e na estrutura do pasto e de suas relações. Os tratamentos foram a combinação de dois espaçamentos entrelinhas e duas densidades de sementes ha-1, sendo 22 ou 44cm entrelinhas e 12 ou 24kg de sementes ha-1. Foram utilizadas 36 novilhas, com idade e peso corporal inicial de 15 meses e 262kg, respectivamente. Os tratamentos E44D24 e E22D12 apresentaram maior tempo de pastejo (469,33 e 467,78 minutos, respectivamente). Os animais do tratamento E44D24 apresentaram menor taxa de bocado (23,99 bocados minuto-1) em relação ao tratamento E22D24 (32,45 bocados minuto-1). Os animais do tratamento E44D12 apresentaram maior número de estações alimentares minuto-1 (9,21) e maior taxa de deslocamento (11,76 passos minuto-1). O espaçamento entrelinhas de plantio de 22cm aumenta o número de bocados estação-1. O aumento na densidade de sementes (24kg ha-1) e a utilização de maiores espaçamentos entrelinhas de plantio aumentam a densidade de folhas nos estratos inferior (0-30cm) e superior (acima de 60cm) do pasto. Os tratamentos E44D12 e E22D24 apresentaram maiores quantidades de colmos no estrato superior do pasto.(AU)
The objective of the study was to evaluate the effects of sorghum pasture implantation with different population arrangements in animal behavior and pasture structure and their relationships. The treatments were the combination of two row lines and two seeds per hectare densities, 22 or 44cm between rows and 12 or 24kg ha -1 of seed. 36 heifers at 15 months of age and 262kg body weight were used. The E44D24 and E22D12 treatments showed higher time of grazing (469.33 and 467.78 minutes, respectively). The animals in E44D24 treatment had lower bit rate (23.99 bites minute -1 ) compared to treatment with E22D24, a higher bit rate (32.45 bits min -1 ). The animals in E44D12 treatment presented the largest number of stations minute -1 (9.21) and higher displacement rate (11.76 steps min -1 ). The row spacing of 22cm increases the number of bits station -1 . The increase in seed density and the use of larger planting row spacing's increase the leaf density of the lower (0-30cm) and higher stratum (above 60cm) of pasture. The E44D12 and E22D24 treatment have higher amounts of stems in the upper stratum of the pasture.(AU)

Background: The decline in fertility rate based on the National Health Profile is attributed to the choice of permanent sterilisation as the preferred method of contraception among Indian women. The uptake of spacing methods has declined over the years in many parts of India related to low awareness about options other than sterilisation. Hence understanding the needs, beliefs and barriers of women regarding contraceptive use can identify the factors behind their choice of contraceptive methods. This study aims to explore the needs, beliefs and barriers of women in using different methods of contraception in a low-resource area of urban Vellore, Tamil Nadu.Methods: A qualitative study was conducted in three underserved areas of urban Vellore served by the secondary care hospital of a private academic institution. A descriptive qualitative method was chosen. Focus group discussion was carried out among study participants. Thematic analysis was used to analyse data.Results: The need for contraceptive use was felt after completing the families determining the type of method chosen. Fear of impending side-effects of commonly available spacing methods of contraception limited their use. The results highlight the forceful use of intra-uterine device among study participants reflecting the incentive-based family planning services implemented in most Indian states.Conclusions: Our study reinforces that neither the availability of contraceptives nor forceful implementation of policies will increase the utilisation of contraceptives. There is a need for community-based education on the indications, types and side-effects of reversible methods of contraception.
ABSTRACT
Background: India is going to be highest populous country within less than a decade. To stabilize population growth as well as to reduce maternal mortality and morbidity resulting from unwanted pregnancy, greater utilization of the spacing methods is essential. In spite of several decades of effort the popularity of Cu-T among the Indian woman is not high. Aim of the study was to find out the profile of the Cu-T acceptor after medical termination of pregnancy (MTP).Methods: It was a retrospective study. Socio-demographic data of the woman accepting Cu-IUCD after MTP was collected from family planning operation theatre record book.Results: The majority of the participants were from rural area. The mean age of the acceptor was 27.28±4.78. The maximum number of woman was para two 74 (44.3%). The number of woman with LCB 2 years or less than 2 years was 96 (57.5%) and that of woman with LCB more than two years was 71 (42.5%).Conclusions: A significant number of woman use Cu-T after a long gap of two years after last child birth. Woman found to be inclined to use Cu-T after having at least one male child.
ABSTRACT
Background: Still many Indian states observe low spaced births and high fertility above replacement level; mostly contributed by disadvantaged society. Factors influencing are entrenched in ignorance, male child desire and traditional culture to some extent.
ABSTRACT
Background: Unmet need for family planning refers to the percentage of fecund women of reproductive age either married or in union, women who either wish to postpone the next birth (spacers) or who wish to stop child bearing (limiters) but are not using a contraceptive method. This clearly indicates a gap between a woman’s reproductive intention and current contraceptive behaviour. The objectives of the present study was to determine the prevalence of unmet need for family planning, to assess the association between socio-demographic characteristics and unmet need of family planning, to identify the reasons for unmet need.Methods: It was a cross-sectional study conducted from June to August 2018 in Ankuli (UHTC). A total of 188 ever married women in the reproductive age group were selected by simple random sampling.Results: Out of 188 women, 41 (21.8%) had no need for contraception and needs for family planning of 78 (41.5%) women had been met. The prevalence of unmet need for family planning was 36.7% consists of 24 (12.8%) spacing need and 45 (23.9%) limiting need. It was found that age, education of women, age at marriage, number of living children, contraceptive knowledge and inter-spousal communication were significantly associated with unmet need for family planning. The most common reason for not using any contraceptive method was fear of side effects (40.6%).Conclusions: The unmet need for family planning was high and in order to reduce the gap, the program should address the above reasons.
ABSTRACT
RESUMEN ANTECEDENTES: El período intergenésico es importante para la planificación de embarazos subsecuentes a partos, cesáreas y abortos. Actualmente existe falta de consenso en cuanto a las definiciones e importancia clínica de la duración del periodo intergenésico; por lo que se realiza esta revisión de la literatura para definir conceptos. MÉTODO: Se realizó una búsqueda bibliográfica en Pubmed y Medline, con periodo de búsqueda del 19992017, con el propósito de identificar publicaciones de relevancia relacionadas a periodo intergenésico. RESULTADOS: Entre los artículos seleccionados, se incluyeron de tipo revisión, originales y guías de práctica clínica. Se considera periodo intergenésico aquel que se encuentra entre la fecha del último evento obstétrico y el inicio del siguiente embarazo. Se sugiere como tiempo recomendado de espera para iniciar un siguiente embarazo mínimo 18 meses (Periodo intergenésico corto, PIC) y no más de 60 meses (Periodo intergenésico largo, PIL), para reducir el riesgo de eventos adversos maternos, perinatales y neonatales. Se debe enfatizar que aunque la dehiscencia de histerorrafia es una grave complicación del PIC menor a 6 meses posterior a una cesárea, no es su única complicación. De igual manera es importante tomar en cuenta el PIL durante la evaluación obstétrica, debido a su asociación con preeclampsia. CONCLUSIONES: Es relevante conocer la terminología adecuada en período intergenésico para evitar complicaciones asociadas a PIC como a PIL. Existe necesidad de estudios clínicos sobre período intergenésico que permitan conocer más consecuencias a corto y largo plazo en nuestra población y tomar medidas para mejorar el desenlace materno-fetal.
ABSTRACT BACKGROUND: Interpregnancy interval is a topic of importance when planning new pregnancies after previous vaginal delivery, cesarean section or abortion. There is currently a lack of consensus in terms of definitions and the clinical importance of interpregnancy interval length, which is the reason to perform a literature review to clarify concepts. METHODS: Published papers from 1999 to 2017 from PubMed/MEDLINE were searched with the purpose of identifying those related to interpregnancy interval. Review articles, original papers, and clinical guidelines in relation to short and long interpregnancy interval were considered. RESULTS: Interpregnancy interval is defined as the period between the last obstetric event and the beginning of the next pregnancy (last menstrual period). Recommended time to initiate the next pregnancy must be at least 18 months (short interpregnancy interval, SII) and no more than 60 months (long interpregnancy interval, LII) to reduce the risk of adverse maternal, perinatal and neonatal outcomes. It is important to emphasize that even though uterine scar dehiscence is a serious complication of SII less than 6 months after a cesarean section, it is not the only complication. It is important to consider LII during obstetric evaluation, due to its association with preeclampsia. CONCLUSION: It is clinically relevant to know the correct definitions of SII and LII to avoid their complications. There is also a need for clinical trials about interpregnancy interval within our population in order to better understand the consequences of SII and LII, thus taking the necessary measures to improve maternal and fetal outcomes.
